Breast and cervical cancer screenings: A systematic economic review of patient navigation services
Chattopadhyay SK , Pillai A , Reynolds J , Jacob V , Ekwueme D , Peng Y , Cuellar AE . Am J Prev Med 2024 INTRODUCTION: This paper examined the economic evidence of patient navigation services to increase breast and cervical cancer screenings among historically disadvantaged racial and ethnic populations and people with lower incomes. METHODS: The literature search strategy for this systematic review included English-language studies conducted in high-income countries that were published from database inception to December 2022. Studies on patients with existing cancer or without healthcare system involvement were excluded. Analysis was completed in January 2023. All monetary values reported are in 2022 U.S. dollars. RESULTS: The search yielded 3 breast cancer, 2 cervical cancer, and 2 multiple cancer studies that combined breast and cervical cancer with other cancer screenings. For breast cancer screening, the intervention cost per patient ranged from $109 to $10,245. Two studies reported $154 and $740 as intervention cost per additional person screened. Changes in healthcare cost per person from 2 studies were $202 and $2,437. Two studies reported cost per quality-adjusted life year (QALY) gained of $3,852 and $39,159 while one study reported cost per life year (LY) gained of $22,889. For cervical cancer, two studies reported intervention cost per person ($103 and $794) and per additional person screened ($56 and $533) with one study reporting a cost per QALY gained ($924). DISCUSSION: All estimates of cost per QALY/LY saved for breast cancer screening were below a conservative threshold of $50,000 indicating that patient navigation services for breast cancer screening were cost-effective. There is limited evidence to determine cost-effectiveness of patient navigation services for cervical cancer screening. |
Clinical outcomes from the Alaska Native Tribal Health Consortium Colorectal Cancer Control Program: 2009-2015
Nash SH , Verhage E , Flanagan C , Haverkamp D , Roik E , Zimpelman G , Redwood D . Int J Environ Res Public Health 2024 21 (5) The Alaska Native Tribal Health Consortium (ANTHC) participated in the United States Centers for Disease Control and Prevention Colorectal Cancer Control Program (CRCCP) from 2009 to 2015. We conducted a descriptive evaluation of ANTHC CRCCP demographics, quality measures, and clinical outcomes, including screening methods employed within the program and screening outcomes. There were 6981 program screenings completed, with the majority (81.3%) of people screened in the 50-75 year age group. Colonoscopy was the primary screening test used, accounting for 6704 (96.9%) of the screening tests. Quality of colonoscopy was high: adequate bowel preparation was reported in 98.2% of colonoscopies, cecal intubation rate was 98.9%, and the adenoma detection rate was 38.9%. A high proportion (58.9%) of colonoscopies had an initial finding of polyps or lesions suspicious for cancer; 41.2% of all colonoscopies had histological confirmation of either adenomatous polyps (40.6%) or cancer (0.5%). The ANTHC CRCCP successfully increased CRC screening among American Indian and Alaska Native peoples living in Alaska; this was achieved primarily through high-quality colonoscopy metrics. These data support a continued focus by the Alaska Native Tribal Health Consortium and its tribal health partners on increasing CRC screening and reducing cancer mortality among Alaska Native peoples. |
Weighted breaths: Exploring biologic and non-biologic therapies for co-existing asthma and obesity
Pilkington AW , Buragamadagu B , Johnston RA . Curr Allergy Asthma Rep 2024 PURPOSE OF REVIEW: To discuss the effectiveness of biologics, some of which comprise the newest class of asthma controller medications, and non-biologics in the treatment of asthma co-existing with obesity. RECENT FINDINGS: Our review of recent preliminary and published data from clinical trials revealed that obese asthmatics respond favorably to dupilumab, mepolizumab, omalizumab, and tezepelumab, which are biologics currently indicated as add-on maintenance therapy for severe asthma. Furthermore, clinical trials are ongoing to assess the efficacy of non-biologics in the treatment of obese asthma, including a glucagon-like peptide-1 receptor agonist, a Janus kinase inhibitor, and probiotics. Although many biologics presently indicated as add-on maintenance therapy for severe asthma exhibit efficacy in obese asthmatics, other phenotypes of asthma co-existing with obesity may be refractory to these medications. Thus, to improve quality of life and asthma control, it is imperative to identify therapeutic options for all existing phenotypes of obese asthma. |
Increasing the writing capacity and dissemination of evaluation findings among US public health practitioners funded to improve cardiovascular health
Scott A , Bostic M , Sreedhara M , McAtee J , Minaya-Junca J , Vaughan M . J Public Health Manag Pract 2024 30 S6-s14 CONTEXT: Contributing to the evidence base, by disseminating findings through written products such as journal articles, is a core competency for public health practitioners. Disseminating practice-based evidence that supports improving cardiovascular health is necessary for filling literature gaps, generating health policies and laws, and translating evidence-based strategies into practice. However, a gap exists in the dissemination of practice-based evidence in public health. Public health practitioners face various dissemination barriers (eg, lack of time and resources, staff turnover) which, more recently, were compounded by the COVID-19 pandemic. PROGRAM: The Centers for Disease Control and Prevention's Division for Heart Disease and Stroke Prevention (DHDSP) partnered with the National Network of Public Health Institutes to implement a multimodal approach to build writing capacity among recipients funded by three DHDSP cooperative agreements. This project aimed to enhance public health practitioners' capacity to translate and disseminate their evaluation findings. IMPLEMENTATION: Internal evaluation technical assistance expertise and external subject matter experts helped to implement this project and to develop tailored multimodal capacity-building activities. These activities included online peer-to-peer discussion posts, virtual writing workshops, resource documents, one-to-one writing coaching sessions, an online toolkit, and a supplemental issue in a peer-reviewed journal. EVALUATION: Findings from an informal process evaluation demonstrate positive results. Most participants were engaged and satisfied with the project's activities. Across eight workshops, participants reported increased knowledge (≥94%) and enhanced confidence in writing (≥98%). The majority of participants (83%) reported that disseminating evaluation findings improved program implementation. Notably, 30 abstracts were submitted for a journal supplement and 23 articles were submitted for consideration. DISCUSSION: This multimodal approach serves as a promising model that enhances public health practitioners' capacity to disseminate evaluation findings during times of evolving health needs. |
Should we be testing for Mycoplasma genitalium on initial presentation? Trends in persistent/recurrent urethritis among men presenting for care in STD clinics, 2015-2019, STD Surveillance Network (SSuN)
Llata E , Tromble E , Schumacher C , Huspeni D , Asbel L , Pathela P , Kohn R , Kerani RP , Barbee L , Bachmann L . Sex Transm Dis 2024 51 (7) 493-498 BACKGROUND: Mycoplasma genitalium is a major contributor to persistent/recurrent urethritis cases. However, there are limited published studies on recent trends of persistent/recurrent urethritis. METHODS: A retrospective analysis was conducted of men presenting with symptomatic urethritis in 16 sexually transmitted disease (STD) clinics from 2015 to 2019. Poisson regression was used to assess trends in the annual proportions of urethritis episodes with follow-up (FU) characterized with persistent/recurrent urethritis symptoms. Results were also stratified by results of chlamydia (CT) and gonorrhea (NG) testing and treatment prescribed. RESULTS: There were 99,897 urethritis episodes, from 67,546 unique men. The proportion of episodes with persistent/recurrent symptomatic FU visits increased 50.8% over a 4-year period (annual percentage change [APC], 11.3%; 95% confidence interval [CI], 6.5-16.3). Similar trends were observed in nonchlamydial nongonococcal urethritis episodes (APC, 12.7%; 95% CI, 6.8-18.9) but increases among those positive for NG (APC, 12.1%; 95% CI, -2.3 to -28.5) or for CT (APC, 7.3%; 95% CI, -6.7 to 23.5) were not statistically significant. Among episodes who received azithromycin as first-line treatment, increases in the proportion of persistent/recurrent FU visits were observed (APC, 12.6%; 95% CI, 8.6-16.7). For episodes where first-line treatment was doxycycline, no significant increases were detected (APC, 4.3%; 95% CI, -0.3 to 9.2). CONCLUSIONS: We found an increase in the proportion of urethritis episodes with persistent or recurrent symptoms over time. Given these observed trends in episodes negative for NG or CT, an etiology not detectable by routine diagnostics was a likely factor in increased persistence, suggesting patients with urethritis may benefit from diagnostic testing for M. genitalium during an initial symptomatic presentation. |
STI and HIV testing and diagnosis among 15-44 years old patients with and without opioid use disorder
Patel CG , DePadilla L , Cuffe KM , Tao G , Gift T . Sex Transm Dis 2024 51 (7) 472-479 BACKGROUND: The association between illicit opioid use and prescription opioid misuse and sexually transmitted infections (STIs) has not been examined recently. Our study aimed to explore differences in STI/HIV care, and delivery of recommended testing and diagnoses among patients with and without opioid use disorder (OUD). METHODS: Using 2019 MarketScan commercial claims data, we identified 15- to 44-year-old male and female patients, to assess the percentages of STI/HIV diagnoses (using International Classification of Diseases, Tenth Revision, Clinical Modification ) and screening (using Current Procedure Terminology codes) among patients with or without OUD diagnoses codes. We further assessed STI/HIV testing and diagnoses by demographic factors. RESULTS: We identified 24,724 patients with OUD codes among 7.31 million patients. Both STI/HIV testing and diagnoses were significantly ( P < 0.05) higher among patients with OUD codes versus without: testing percentages were 16.81% versus 12.93% for chlamydia, 22.31% versus 16.62% for gonorrhea, 15.26% versus 7.61% for syphilis, and 18.18% versus 7.60% for HIV; diagnoses were 0.80% versus 0.35% for chlamydia, 0.30% versus 0.11% for gonorrhea, 0.23% versus 0.07% for syphilis, and 0.74% versus 0.33% for HIV. Similarly, among 0.53 million 15- to 24-year-old females who received services suggestive of sexual activity, chlamydia testing was significantly ( P < 0.05) higher among patients with OUD codes versus without (59.78% vs. 55.66%). CONCLUSIONS: Patients with OUD codes have higher percentages of STI/HIV testing and diagnoses codes compared with those without OUD codes. Clinicians may want to consider a comprehensive multidisciplinary (OUD and STI prevention) approach in patient care and provide recommended STI/HIV screening among patients with OUD if not performed. |

SARS-CoV-2 incidence, seroprevalence, and antibody dynamics in a rural, population-based cohort: March 2020 - July 2022
Petrie JG , Pattinson D , King JP , Neumann G , Guan L , Jester P , Rolfes MA , Meece JK , Kieke BA , Belongia EA , Kawaoka Y , Nguyen HQ . Am J Epidemiol 2024 Studies of SARS-CoV-2 incidence are important for response to continued transmission and future pandemics. We followed a rural community cohort with broad age representation with active surveillance for SARS-CoV-2 identification from November 2020 through July 2022. Participants provided serum specimens at regular intervals and following SARS-CoV-2 infection or vaccination. We estimated the incidence of SARS-CoV-2 infection identified by study RT-PCR, electronic health record documentation or self-report of a positive test, or serology. We also estimated the seroprevalence of SARS-CoV-2 spike and nucleocapsid antibodies measured by ELISA. Overall, 65% of the cohort had ≥1 SARS-CoV-2 infection by July 2022, and 19% of those with primary infection were reinfected. Infection and vaccination contributed to high seroprevalence, 98% (95% CI: 95%, 99%) of participants were spike or nucleocapsid seropositive at the end of follow-up. Among those seropositive, 82% were vaccinated. Participants were more likely to be seropositive to spike than nucleocapsid following infection. Infection among seropositive individuals could be identified by increases in nucleocapsid, but not spike, ELISA optical density values. Nucleocapsid antibodies waned more quickly after infection than spike antibodies. High levels of SARS-CoV-2 population immunity, as found in this study, are leading to changing epidemiology necessitating ongoing surveillance and policy evaluation. |

De Schacht C , Lucas C , Paulo P , Naftal Fernando A , Ernesto Chinai J , Silva WP , Amane G , Sultane T , Honwana N , Malimane I , Couto A , Yu Z , Wester CW . PLoS One 2024 19 (6) e0305391 BACKGROUND: In 2021, Mozambique initiated community-based oral HIV self-testing (HIVST) to increase testing access and uptake among priority groups, including adult males, adolescents, and young adults. Within an HIVST pilot project, we conducted a performance evaluation assessing participants' ability to successfully conduct HIVST procedures and interpret results. METHODS: A cross-sectional study was performed between February-March 2021 among employees, students (18-24 years of age), and community members, using convenience sampling, in two rural districts of Zambézia Province, Mozambique. We quantified how well untrained users performed procedures for the oral HIVST (Oraquick®) through direct observation using a structured checklist, from which we calculated an HIVST usability index (scores ranging 0-100%). Additionally, participants interpreted three previously processed anonymous HIVST results. False reactive and false non-reactive interpretation results were presented as proportions. Bivariate analysis was conducted using Chi-square and Fisher exact tests. RESULTS: A total of 312 persons participated (131[42%] community members, 71[23%] students, 110[35%] employees); 239 (77%) were male; the mean age was 28 years (standard deviation 10). Average usability index scores were 80% among employees, 86% among students, and 77% among community members. Main procedural errors observed included "incorrect tube positioning" (49%), "incorrect specimen collection" (43%), and "improper waiting time for result interpretation" (42%). From the presented anonymous HIVST results, 75% (n = 234) correctly interpreted all three results, while 9 (3%) of study participants failed to correctly interpret any results. Overall, 36 (12%) gave a false non-reactive result interpretation, 21 (7%) a false reactive result interpretation, and 14 (4%) gave both false non-reactive and false reactive result interpretations. Community members generally had lower performance. CONCLUSIONS: Despite some observed testing procedural errors, most users could successfully perform an HIVST. Educational sessions at strategic places (e.g., schools, workplaces), and support via social media and hotlines, may improve HIVST performance quality, reducing the risk of incorrect interpretation. |
Loss to follow-up among people living with HIV on tuberculosis preventive treatment at four regional referral hospitals, Uganda, 2019–2021
Juniour Nsubuga E , Lukoye D , Kabwama SN , Martha Migamba S , Komakech A , Sarah E , Nampeera R , Nakazzi R , Magona Nerima S , Kirabo J , Bulage L , Kwesiga B , Riolexus Ario A . J Clin Tuberc Other Microbact Dis 2024 36 Introduction: Tuberculosis (TB) remains the leading cause of death among people living with HIV (PLHIV). TB preventive treatment (TPT) can prevent active TB infection in PLHIV for several years after it is completed. During 2019–2021, the six-month course of TPT (using isoniazid) was the most readily available in Uganda; however, program data indicated a TPT program loss to follow-up (LTFU) rate of 12 % during this period. We evaluated factors associated with TPT LTFU among PLHIV in four regional referral hospitals (RRHs) in Uganda from 2019 to 2021. Methods: We abstracted program data from TPT registers on patient LTFU at Masaka, Mbale, Mubende, and Jinja RRHs. Additional data collected included client demographics, duration on HIV antiretroviral therapy (ART), year of TPT initiation, adherence, and point of entry. LTFU was defined as the failure to finish six consecutive months of isoniazid without stopping for more than two months at a time. We conducted bivariate analysis using the chi-square test for independence. Variables with p < 0.05 in bivariate analysis were included in a logistic regression model to establish independent factors associated with LTFU. Results: Overall, 24,206 clients were started on TPT in the four RRHs. Their median age was 40 years (range, 1–90 years), and 15,962 (66 %) were female. A total of 22,260 (92 %) had TPT adherence >95 %. Independent factors associated with LTFU included being on ART for <3 months (AOR: 3.1, 95 % CI: 2.1–4.5) and 20–24 years (AOR: 4.7, 95 % CI: 1.9–12) or 25–29 years (AOR: 3.3, 95 % CI: 1.3–8.2) compared to 15–19 years. Conclusions: PLHIV just starting ART and young adults had higher odds of being LTFU from TPT during 2019–2021 in the four RRHs. Close follow-up of PLHIV aged 20–29 years and those newly initiated on ART could improve TPT completion. © 2024 The Author(s) |
Recent use of consumer and personal care products and exposures to select endocrine disrupting chemicals among urban children with asthma
Fandiño-Del-Rio M , Matsui EC , Calafat AM , Koehl R , Botelho JC , Woo H , Boyle M , Hansel NN , McCormack M , Quirós-Alcalá L . J Expo Sci Environ Epidemiol 2024 BACKGROUND: Emerging studies suggest that endocrine disrupting chemicals (EDCs) in personal care and other consumer products are linked with various adverse health effects, including respiratory and reproductive effects. Despite Black persons using more personal care products than other demographic groups and having a high asthma burden, little is known regarding their consumer product use patterns and associated EDC exposures. OBJECTIVE: To examine the association between recent exposure to select EDCs with specific consumer products and behaviors in a cohort of 110 predominantly Black children with asthma, ages 8-17 years, living in Baltimore City, Maryland. METHODS: We quantified concentrations of bisphenol A (BPA), bisphenol S (BPS), bisphenol F, two dichlorophenols, four parabens, triclosan, benzophenone-3, and triclocarban in spot urine samples. Questionnaires were used to capture recent (last 24-h) consumer product use and behaviors. Associations between EDCs and consumer product uses/behaviors were assessed using multivariable linear regression, adjusting for age, gender, race/ethnicity, and caregiver income level. Effect estimates were expressed as geometric mean ratios of biomarker concentrations of product-users vs non-users. RESULTS: Increased concentrations to select EDCs were associated with recent use of air freshener (ratios; BPA: 1.9, 95%CI 1.4-2; BPS 1.7, 95%CI 1-2.97; propyl paraben: 3.0, 95%CI 1.6-5.6), scented candles (methyl paraben: 2.6, 95%CI 1.1-6.1), and scented carpet powder (2,5-dichlorophenol: 2.8, 95%CI 1.2-6.3). Additionally, consuming canned food was associated with some increased biomarker concentrations (ratios: BPA: 1.7, 95%CI 1.2-2.4; BPS: 2.1, 95% CI: 1.2-3.6). SIGNIFICANCE: These findings add to the body of evidence suggesting that recent use of select consumer products in Black children contributes to exposure of chemicals of concern and could potentially inform exposure mitigation interventions. Findings have broad potential health implications for pediatric populations and Black children who may face exposure and health disparities. IMPACT: Little is known about how children's personal care product use and consumer behaviors affect their exposures to endocrine disrupting chemicals (EDCs). This is particularly true for Black children who often experience a disparate exposure burden to many EDCs. This is a significant knowledge gap among children that are uniquely vulnerable to EDCs as they undergo critical windows of growth and development. Our findings show associations between consumer products and EDC exposures in predominantly Black children in low-income settings. Identifying EDC exposure determinants has broad health implications as many of these chemicals have been associated with adverse health risks. |
Serum dioxin levels in a subset of participants of the East Palestine, Ohio train derailment health tracking study
Haynes EN , Eskenazi B , Hilbert TJ , Brancato C , Holland N , Kim C , Calafat AM , Jones R , Davis M , Birnbaum LS , Sjodin A . Environ Sci Techno Lett 2024 A February 3, 2023 train derailment and subsequent burn released hazardous chemicals into East Palestine, Ohio. One potential exposure was polychlorinated dibenzo-p-dioxins, dibenzofurans, and coplanar polychlorinated biphenyls (cPCBs), collectively referred to as dioxins. Many studies have linked dioxins to numerous health effects. A pilot study was conducted July 17-18, 2023 to assess residents’ serum dioxin levels. Eighteen persons who were White, nonsmokers with a mean age of 55, and 56% female, provided serum for analysis. Measurement of 20 dioxins, furans, and cPCBs congeners was conducted using gas chromatography, isotope dilution, and high-resolution mass spectrometry. A toxic equivalency (TEQ) value for each participant was calculated by multiplying the reported concentration of each congener by its toxic equivalency factor and summing the results. TEQs were compared to 2011-2012 National Health and Nutrition Examination Survey (NHANES) data by race/ethnicity, sex, and age group. All participants had serum TEQ values either below or within the range of NHANES values. Mean TEQ values were lower in younger age groups; we observed no sex-specific differences. These pilot data demonstrate that although dioxins may have formed during the derailment, exposures to participants did not increase their TEQ values compared with 2011-2012 NHANES. © 2024 American Chemical Society. |
Maternal periconceptional exposure to drinking water disinfection by-products and neural tube defects in offspring
Kancherla V , Rhoads A , Conway KM , Suhl J , Langlois PH , Hoyt AT , Shaw GM , Evans SP , Moore CA , Luben TJ , Michalski A , Feldkamp ML , Romitti PA . Birth Defects Res 2024 116 (6) e2370 BACKGROUND: Associations between maternal periconceptional exposure to disinfection by-products (DBPs) in drinking water and neural tube defects (NTDs) in offspring are inconclusive, limited in part by exposure misclassification. METHODS: Maternal interview reports of drinking water sources and consumption from the National Birth Defects Prevention Study were linked with DBP concentrations in public water system monitoring data for case children with an NTD and control children delivered during 2000-2005. DBPs analyzed were total trihalomethanes, the five most common haloacetic acids combined, and individual species. Associations were estimated for all NTDs combined and selected subtypes (spina bifida, anencephaly) with maternal periconceptional exposure to DBPs in public water systems and with average daily periconceptional ingestion of DBPs accounting for individual-level consumption and filtration information. Mixed effects logistic regression models with maternal race/ethnicity and educational attainment at delivery as fixed effects and study site as a random intercept were applied. RESULTS: Overall, 111 case and 649 control children were eligible for analyses. Adjusted odds ratios for maternal exposure to DBPs in public water systems ranged from 0.8-1.5 for all NTDs combined, 0.6-2.0 for spina bifida, and 0.7-1.9 for anencephaly; respective ranges for average daily maternal ingestion of DBPs were 0.7-1.1, 0.5-1.5, and 0.6-1.8. Several positive estimates (≥1.2) were observed, but all confidence intervals included the null. CONCLUSIONS: Using community- and individual-level data from a large, US, population-based, case-control study, we observed statistically nonsignificant associations between maternal periconceptional exposure to total and individual DBP species in drinking water and NTDs and subtypes. |
Using wastewater surveillance for mpox as a complement to traditional case-based reporting - Chicago, March-June 2023

Environ Int 2024 190 108749 The Chicago Department of Public Health tested wastewater samples for the presence of Monkeypox Virus (MPXV) from March 13 through June 26, 2023. There were persistent detections prior to reported cases. This indicated the baseline levels of MPXV prevalence might warrant routine monitoring. Detections in areas without corresponding reported clinical cases might highlight areas where cases are being under-reported by traditional surveillance. |
The 2018-2019 FoodNet Population Survey: A tool to estimate risks and behaviors associated with enteric infections
Devine CJ , Molinari NA , Shah HJ , Blackstock AJ , Geissler A , Marder EP , Payne DC . Am J Epidemiol 2024 The FoodNet Population Survey is a periodic survey of randomly selected residents in 10 US sites on exposures and behaviors that may be associated with acute diarrheal infections and the health care sought for those infections. This survey is used to estimate the true disease burden of enteric illness in the United States and to estimate rates of exposure to potential sources of illness. Unlike previous FoodNet Population Surveys, this cycle used multiple sampling frames and administration modes, including cell phone and web-based questionnaires, that allowed for additional question topics and a larger sample size. It also oversampled children to increase representation of this population. Analytic modeling adjusted for mode effects when estimating the prevalence estimates of exposures and behaviors. This report describes the design, methodology, challenges, and descriptive results from the 2018-19 FoodNet Population Survey. |

Multiple imputation of race and Hispanic ethnicity in national surveillance data for chlamydia, gonorrhea, and syphilis
Pondo T , Torrone E , Pagaoa M . Sex Transm Dis 2024 BACKGROUND: Disease burden of sexually transmitted infections such as chlamydia, gonorrhea, and syphilis is often compared across age categories, sex categories, and race and ethnicity categories. Missing data may prevent researchers from accurately characterizing health disparities between populations. This article describes the methods used to impute race and Hispanic ethnicity in a large national surveillance data set. METHODS: All US cases of chlamydia, gonorrhea, and syphilis (excluding congenital syphilis) reported through the National Notifiable Diseases Surveillance System (NNDSS) from the year 2019 were included in the analyses. We used fully conditional specification to impute missing race and Hispanic ethnicity data. After imputation, reported case rates were calculated, by disease, for each race and Hispanic ethnicity category using Vintage 2019 Population and Housing Unit Estimates from the US Census. We then used case counts from subsets that contained only complete race and Hispanic ethnicity information to investigate if the confidence intervals from the multiply imputed data included the observed number of cases in each race and Hispanic ethnicity category. RESULTS: Among the 2,553,038 cases reported in 2019, race and Hispanic ethnicity were multiply imputed for 9% of syphilis cases, 22% of gonorrhea cases and 33% of chlamydia cases. In the subset analyses, every non-zero rate of reported cases was contained within the confidence intervals that were calculated from multiply imputed data. CONCLUSIONS: Confidence intervals that account for the uncertainty of the predictions are an advantage of multiple imputation over complete-case analysis because a realistic variance estimate allows for valid hypothesis testing results. |
Fungal infections and social determinants of health: Using data to identify disparities
Williams SL , Benedict K , Toda M . Curr Fungal Infect Rep 2024 18(2) 88-94 Purpose of Review: Fungal diseases disproportionately affect certain demographic populations, but few studies have thoroughly investigated the drivers of those disparities. We summarize data sources that can be considered to explore potential associations between fungal diseases and social determinants of health in the United States. Recent Findings: Sociodemographic disparities are apparent in fungal diseases, and social determinants of health (e.g., income, living conditions, and healthcare access) may be associated with increased risk of infection, severe disease, and poor health outcomes. Summary: Numerous data sources are available in the United States to analyze the potential association between fungal diseases and underlying social determinants of health. Each source has benefits and limitations that should be considered in the development of analysis plans. Inherent challenges to all fungal disease data (e.g., underdiagnosis, underreporting, and inability to detect people who do not seek medical care) should be noted and accounted for in interpretation of results.

A six-year follow-up of bloodstream infections in hemodialysis facilities in the United States, National Healthcare Safety Network, 2020
Keenan J , Barbre KA , Dollard P , Hoxworth T , Qureshi I , Dunham L , O'Leary E , Nuwoaty SA , Bagchi S , Edwards J , Lu M , Benin A , Bell J . Clin J Am Soc Nephrol 2024 METHODS: Outpatient hemodialysis facilities report BSI events to NHSN. Pooled mean rates with 95% CI were calculated overall and for each type of vascular access (arteriovenous (AV) fistula, AV graft, or a central venous catheter (CVC)). Standardized infection ratios were calculated as observed BSI events divided by the predicted number of events based on national aggregate data. Median facility-level standardized infection ratios and 95% confidence intervals (CIs) were stratified by state and US territory. RESULTS: During 2020, 7,183 outpatient hemodialysis facilities reported data for 5,235,234 patient months with 15,181 BSI events. Pooled mean rates per 100 person-months were 0.29 (95% CI, 0.29-0.30) overall, 0.80 (95% CI, 0.78-0.82) for CVC, 0.12 (95% CI, 0.12-0.12) for AV fistula, 0.21 (95% CI, 0.20-0.22) for AV graft, and 0.28 (95% CI, 0.19-0.40) for other access types. The national standardized infection ratio was 0.40 (95% CI, 0.39-0.41). South Dakota had a standardized infection ratio significantly higher than one (1.34; 95% CI, 1.11 - 1.62). Fifty-one of 54 states and territories had BSI standardized infection ratio significantly lower than one. CONCLUSIONS: In 2020, the median standardized infection ratio for BSI in US outpatient hemodialysis facilities was lower than predicted overall and in almost all states and territories.

Johnston C , Scheele S , Bachmann L , Boily MC , Chaiyakunapruk N , Deal C , Delany-Moretlwe S , Lee S , Looker K , Marshall C , Mello MB , Ndowa F , Gottlieb S . Vaccine 2024 Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) are chronic, highly prevalent viral infections that cause significant morbidity around the world. HSV-2 is sexually transmitted and is the leading cause of genital ulcer disease (GUD). It also increases the risk of HIV acquisition, fueling the HIV epidemic. HSV-1 is typically acquired in childhood through nonsexual contact and contributes to oral and ocular disease, but it can also be sexually transmitted to cause GUD. Both HSV-1 and HSV-2 cause neonatal herpes and neurologic disease. Given the ubiquitous nature of HSV-1 and HSV-2 infections and the limited existing prevention and control measures, vaccination would be the most efficient strategy to reduce the global burden of morbidity related to HSV infection. Vaccine strategies include prophylactic vaccination, which would prevent infection among susceptible persons and would likely be given to adolescents, and therapeutic vaccinations, which would be given to people with symptomatic genital HSV-2 infection. This document discusses the vaccine value profile of both types of vaccines. This ‘Vaccine Value Profile’ (VVP) for HSV is intended to provide a high-level, holistic assessment of the information and data that are currently available to inform the potential public health, economic and societal value of pipeline vaccines and vaccine-like products. This VVP was developed by subject matter experts from academia, non-profit organizations, government agencies and multi-lateral organizations. All contributors have extensive expertise on various elements of the HSV VVP and collectively aimed to identify current research and knowledge gaps. The VVP was developed using only existing and publicly available information. © 2024 The Authors |

Vaccine 2024 Community engagement is vital to the development of people-centered, successful vaccination programs. The diverse Vaccination Acceptance Research Network (VARN) community brings together interdisciplinary professionals from across the immunization ecosystem who play a crucial role in vaccination acceptance, demand, and delivery. Over the course of the VARN2023 conference, researchers and practitioners alike shared ideas and experiences focused on strategies and approaches to building trust between communities and health systems to increase equity in vaccination. Health professionals and community members must have equal value in the design and delivery of community-centered immunization services, while key vaccination decision-makers must also consider community experiences, concerns, and expertise in program design and policymaking. Therefore, strategies for community engagement and cultivating trust with communities are crucial for the success of any immunization program. Furthermore, health workers need additional skills, support, and resources to effectively communicate complex information about immunization, including effective strategies for countering misinformation. This article summarizes three skills-building sessions offered at the VARN2023 conference, focused on human-centered design, motivational interviewing, and engaging with journalists to leverage the voices of communities. These sessions offered practical, evidence-based tools for use across geographic and social settings that can be used by practitioners, researchers, and other stakeholders to increase vaccination demand and uptake in their communities. |

Vaccine 2024 BACKGROUND: The rVSVΔG-ZEBOV-GP Ebola vaccine (rVSV-ZEBOV) has been used in response to Ebola disease outbreaks caused by Ebola virus (EBOV). Understanding Ebola knowledge, attitudes, and practices (KAP) and the long-term immune response following rVSV-ZEBOV are critical to inform recommendations on future use. METHODS: We administered surveys and collected blood samples from healthcare workers (HCWs) from seven Ugandan healthcare facilities. Questionnaires collected information on demographic characteristics and KAP related to Ebola and vaccination. IgG ELISA, virus neutralization, and interferon gamma ELISpot measured immunological responses against EBOV glycoprotein (GP). RESULTS: Overall, 37 % (210/565) of HCWs reported receiving any Ebola vaccination. Knowledge that rVSV-ZEBOV only protects against EBOV was low among vaccinated (32 %; 62/192) and unvaccinated (7 %; 14/200) HCWs. Most vaccinated (91 %; 192/210) and unvaccinated (92 %; 326/355) HCWs wanted to receive a booster or initial dose of rVSV-ZEBOV, respectively. Median time from rVSV-ZEBOV vaccination to sample collection was 37.7 months (IQR: 30.5, 38.3). IgG antibodies against EBOV GP were detected in 95 % (61/64) of HCWs with vaccination cards and in 84 % (162/194) of HCWs who reported receiving a vaccination. Geometric mean titer among seropositive vaccinees was 0.066 IU/mL (95 % CI: 0.058-0.076). CONCLUSION: As Uganda has experienced outbreaks of Sudan virus and Bundibugyo virus, for which rVSV-ZEBOV does not protect against, our findings underscore the importance of continued education and risk communication to HCWs on Ebola and other viral hemorrhagic fevers. IgG antibodies against EBOV GP were detected in most vaccinated HCWs in Uganda 2─4 years after vaccination; however, the duration and correlates of protection warrant further investigation. |
Migration from Epi Info to District Health Information Software 2 for Vaccine-Preventable Disease Surveillance - World Health Organization African Region, 2019-2023

MMWR Morb Mortal Wkly Rep 2024 73 (23) 529-533 High-quality vaccine-preventable disease (VPD) surveillance data are critical for timely outbreak detection and response. In 2019, the World Health Organization (WHO) African Regional Office (AFRO) began transitioning from Epi Info, a free, CDC-developed statistical software package with limited capability to integrate with other information systems, affecting reporting timeliness and data use, to District Health Information Software 2 (DHIS2). DHIS2 is a free and open-source software platform for electronic aggregate Integrated Disease Surveillance and Response (IDSR) and case-based surveillance reporting. A national-level reporting system, which provided countries with the option to adopt this new system, was introduced. Regionally, the Epi Info database will be replaced with a DHIS2 regional data platform. This report describes the phased implementation from 2019 to the present. Phase one (2019-2021) involved developing IDSR aggregate and case-based surveillance packages, including pilots in the countries of Mali, Rwanda, and Togo. Phase two (2022) expanded national-level implementation to 27 countries and established the WHO AFRO DHIS2 regional data platform. Phase three (from 2023 to the present) activities have been building local capacity and support for country reporting to the regional platform. By February 2024, eight of 47 AFRO countries had adopted both the aggregate IDSR and case-based surveillance packages, and two had successfully transferred VPD surveillance data to the AFRO regional platform. Challenges included limited human and financial resources, the need to establish data-sharing and governance agreements, technical support for data transfer, and building local capacity to report to the regional platform. Despite these challenges, the transition to DHIS2 will support efficient data transmission to strengthen VPD detection, response, and public health emergencies through improved system integration and interoperability. |
Validation of Multi-state EHR-Based Network for Disease Surveillance (MENDS) Data and implications for improving data quality and representativeness
Hohman KH , Klompas M , Zambarano B , Wall HK , Jackson SL , Kraus EM . Prev Chronic Dis 2024 21 E43 INTRODUCTION: Surveillance modernization efforts emphasize the potential use of electronic health record (EHR) data to inform public health surveillance and prevention. However, EHR data streams vary widely in their completeness, accuracy, and representativeness. METHODS: We developed a validation process for the Multi-State EHR-Based Network for Disease Surveillance (MENDS) pilot project to identify and resolve data quality issues that could affect chronic disease prevalence estimates. We examined MENDS validation processes from December 2020 through August 2023 across 5 data-contributing organizations and outlined steps to resolve data quality issues. RESULTS: We identified gaps in the EHR databases of data contributors and in the processes to extract, map, integrate, and analyze their EHR data. Examples of source-data problems included missing data on race and ethnicity and zip codes. Examples of data processing problems included duplicate or missing patient records, lower-than-expected volumes of data, use of multiple fields for a single data type, and implausible values. CONCLUSION: Validation protocols identified critical errors in both EHR source data and in the processes used to transform these data for analysis. Our experience highlights the value and importance of data validation to improve data quality and the accuracy of surveillance estimates that use EHR data. The validation process and lessons learned can be applied broadly to other EHR-based surveillance efforts. |

Firearm storage behaviors - Behavioral Risk Factor Surveillance System, eight states, 2021-2022
Friar NW , Merrill-Francis M , Parker EM , Siordia C , Simon TR . MMWR Morb Mortal Wkly Rep 2024 73 (23) 523-528 Secure firearm storage might help reduce access by children and other unauthorized users and the related risk for injury or death. Information about state-specific prevalence of firearm storage practices can be used to develop secure storage messages and programs; however, such information is often unavailable. Data from the Behavioral Risk Factor Surveillance System, by respondent characteristics, were used to estimate prevalence of keeping firearms in or around the home and related storage practices for eight states that administered the firearm safety module in 2021 or 2022. Overall, 18.4% (California) to 50.6% (Alaska) of respondents reported that a firearm was kept in or around their home. Among those with a firearm in or around the home, 19.5% (Minnesota) to 43.8% (North Carolina) reported that a firearm was stored loaded. Across all eight states, approximately one half of those with a loaded firearm stored at least one loaded firearm unlocked. Among respondents with a child and a loaded firearm in the home, 25.2% (Ohio) to 41.4% (Alaska) reported that a loaded firearm was stored unlocked. Variability in firearm storage practices highlights the importance of local data and suggests opportunities to tailor prevention efforts to specific population groups to reduce risk for firearm handling by children without adult supervision, and other unauthorized persons. |
A pilot study of the outcomes of human trafficking survivors assessment with girls who have experienced commercial sexual exploitation
Helpingstine C , Kenny MC , Rubiales R . Eval Program Plann 2024 106 102462 PURPOSE: This study utilized the Outcome of Human Trafficking Survivors (OHTS) to monitor the progress of female victims of CSE over a year while they were enrolled in a comprehensive treatment program. METHODS: Sixty-seven girls (M age 17.70 years) who were identified as confirmed victims of CSE (46 %) or at risk for CSE (54 %) and presented for treatment were administered the OHTS upon intake into the program and again at 90 day intervals resulting in four data points. Ratings were provided by staff members who interact with the member in each area assessed. A repeated-measures ANOVA was conducted comparing mean outcome differences across all four timepoints. RESULTS: Results indicate that significant changes were found in the area of Housing and Education, with gains in Education over time. For this sample, Parenting and Immigration were domains of less relevance and data was not consistently obtained in these areas. Other categories assessed by the OHTS did not demonstrate significant changes over time. CONCLUSION: The OHTS can be used to track progress of clients enrolled in treatment programming, but the goals of the program should align with the categories that are assessed in the OHTS. Repeated administration may be difficult due to high dropout rates in treatment and there may be rater bias. |
Comparison of SARS-CoV-2 seroprevalence estimates between commercial lab serum specimens and blood donor specimens, United States, September-December 2021
Kao SZ , Nycz E , Benoit TJ , Clarke KEN , Jones JM . Microbiol Spectr 2024 e0012324 We estimated monthly cross-sectional seroprevalence rates of anti-nucleocapsid (anti-N) and anti-spike (anti-S) antibodies to severe acute respiratory syndrome coronavirus 2 in two U.S. nationwide studies. The nationwide blood donor seroprevalence (NBDS) study included specimens from blood donors, while the nationwide commercial laboratory seroprevalence (NCLS) study included residual serum specimens tested in commercial laboratories for reasons unrelated to the assessment of coronavirus disease 2019 infection. In September-December 2021, specimens collected from both nationwide studies were tested for anti-N antibodies. In September-October 2021, specimens from both studies within a five-state area were tested for anti-S antibodies. We used raking methods to adjust all seroprevalence estimates by the population distribution of key demographics in included states. Seroprevalence estimates of each antibody type were compared across the two studies for specimens drawn in the same U.S. states during the same time period. Our analysis revealed that over a 4-month period, national NCLS monthly anti-N estimates were 0.5-1.9 percentage points higher than NBDS estimates. In contrast, across five states during a 2-month period, NBDS anti-S estimates were 7.6 and 8.2 percentage points higher than NCLS estimates. The observed differences in seroprevalence estimates between the NBDS and NCLS studies may be attributed to variations in the characteristics of the study sample populations, particularly with respect to health status, health behaviors, and vaccination status. These differences should be considered in the interpretation of seroprevalence study results based on blood donors or commercial lab residual specimens. IMPORTANCE: This study was the first systematic comparison between two nationwide severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) studies which estimated seroprevalence, or the proportion of the population with antibodies to the virus, using differing convenience sample populations. One study tested blood donor specimens; the other study tested specimens left over from clinical blood tests. The seroprevalence of anti-nucleocapsid and anti-spike antibodies was compared in the same states during the same months with statistical adjustments based on state demographics. Similar anti-nucleocapsid antibody seroprevalence estimates produced by two independent studies using differing convenience samples build confidence in the generalizability of their anti-nucleocapsid findings. Due to high blood donor vaccine rates, blood donor SARS-CoV-2 anti-spike antibody estimates might overestimate general population seroprevalence, an important consideration for interpreting national seroprevalence study results. Furthermore, because laboratory residuals and blood donations are two common sources of specimens for seroprevalence studies, study findings may be informative for other respiratory virus seroepidemiology studies. |

Open Biol 2024 14 (6) 230363 We present a novel small molecule antiviral chemotype that was identified by an unconventional cell-free protein synthesis and assembly-based phenotypic screen for modulation of viral capsid assembly. Activity of PAV-431, a representative compound from the series, has been validated against infectious viruses in multiple cell culture models for all six families of viruses causing most respiratory diseases in humans. In animals, this chemotype has been demonstrated efficacious for porcine epidemic diarrhoea virus (a coronavirus) and respiratory syncytial virus (a paramyxovirus). PAV-431 is shown to bind to the protein 14-3-3, a known allosteric modulator. However, it only appears to target the small subset of 14-3-3 which is present in a dynamic multi-protein complex whose components include proteins implicated in viral life cycles and in innate immunity. The composition of this target multi-protein complex appears to be modified upon viral infection and largely restored by PAV-431 treatment. An advanced analog, PAV-104, is shown to be selective for the virally modified target, thereby avoiding host toxicity. Our findings suggest a new paradigm for understanding, and drugging, the host-virus interface, which leads to a new clinical therapeutic strategy for treatment of respiratory viral disease. |
Longitudinal viral load outcomes of adults with HIV after detectable viremia on tenofovir, lamivudine, and dolutegravir
Sodeke O , Milligan K , Ezeuko I , Oladipo A , Emeh A , Bashorun A , Orisawayi O , Danjuma S , Onotu D , Boyd AM , Abutu A , Chun H , Vallabhaneni S . Aids 2024 BACKGROUND: :To inform optimal management of HIV viremia on TLD, we examined viral load (VL) outcomes of a large cohort of adult PLHIV on TLD in Nigeria. METHODS: :We conducted a retrospective study of adult PLHIV who had ≥1 VL after initiating TLD during January 2017-February 2023. VLs were categorized as undetectable (≤50 copies/mL), low low-level viremia (LLV, 51-199 copies/mL), high LLV (200-999 copies/mL), virologic nonsuppression (VLNS, ≥1000 copies/mL), and virologic failure (VF, ≥2 consecutive VLNS results). Among patients with ≥2 VLs on TLD, we described how viremia changed over time and examined virologic outcomes after VF. We identified predictors of subsequent VLNS using mixed-effects logistic regression and conducted planned contrasts between levels of VL result and regimen types. RESULTS: :Analysis of 82,984 VL pairs from 47,531 patients demonstrated viral resuppression to ≤50 copies/mL at follow-up VL in 66.7% of those with initial low LLV, 59.1% of those with initial high LLV, and 48.9% of those with initial VLNS. Of 662 patients with a follow-up VL after VF, 94.6% stayed on TLD; of which 57.8% (359/621) were undetectable at next VL without regimen change. Previous low LLV (aOR 1.74, 1.56-1.93), high LLV (aOR 2.35, 2.08-2.65), and VLNS (aOR 6.45, 5.81-7.16) were associated with increasingly higher odds of subsequent VLNS, whereas a previously undetectable VL (aOR 1.08, 0.99-1.71) on TLD was not. CONCLUSIONS: :Despite increased odds of subsequent VLNS, most PLHIV with detectable viremia on TLD, including those with VF, will resuppress to an undetectable VL without a regimen change. |
"Your child should not return": Preschool expulsion among children with attention-deficit/hyperactivity disorder as an early indicator of later risks
Claussen AH , Wolicki SB , Danielson ML , Hutchins HJ . J Dev Behav Pediatr 2024 OBJECTIVE: Young children with attention-deficit/hyperactivity disorder (ADHD) can have challenging behaviors putting them at risk for preschool expulsion and for adverse outcomes across child development, health, and education. We examined the association of preschool expulsion with ADHD symptoms, diagnosis, treatment, and functioning among children with ADHD. METHODS: Using the cross-sectional National Survey of the Diagnosis and Treatment of ADHD and Tourette Syndrome on 2947 children aged 5 to 17 years ever diagnosed with ADHD, parents reported on preschool expulsion, ADHD symptoms, diagnosis, treatment, and functioning. Weighted analyses included calculations of estimated means, prevalence, and prevalence ratios. RESULTS: Preschool expulsion was experienced by 4.4% of children ever diagnosed with ADHD (girls: 1.5%; boys: 5.7%). Children with preschool expulsion had lower mean ages at first concern about ADHD symptoms, ADHD diagnosis, and initiation of ADHD medication and had higher prevalence of severe ADHD symptoms and other mental, behavioral, or developmental disorders. A history of preschool expulsion was associated with difficulties with overall school performance, organized activities, writing, handwriting, and the parent-child relationship, but not with math, reading, or peer or sibling relationships. Children with preschool expulsion more often received school supports, behavioral classroom management, peer intervention, and social skills training. CONCLUSION: Among children ever diagnosed with ADHD, history of preschool expulsion was associated with more severe ADHD symptoms, other disorders, earlier diagnosis and medication initiation, and academic and social impairment. Health care providers can use preschool expulsion as an indicator of risk for children with ADHD and connect families to effective treatments. |
Dolutegravir- versus efavirenz-based treatment in pregnancy: Impact on red blood cell folate concentrations in pregnant women and their infants

J Infect Dis 2024 In IMPAACT 2010/VESTED, pregnant women were randomized to initiate dolutegravir (DTG)+emtricitabine (FTC)/tenofovir alafenamide (TAF), DTG+FTC/tenofovir disoproxil fumarate (TDF), or efavirenz (EFV)/FTC/TDF. We assessed red blood cell folate concentrations (RBC-folate) at maternal study entry and delivery, and infant birth. RBC-folate outcomes were: 1) maternal change entry to delivery (trajectory), 2) infant, 3) ratio of infant-to-maternal delivery. Generalized estimating equation models for each log(folate) outcome were fit to estimate adjusted geometric mean ratio (Adj-GMR)/GMR trajectories (Adj-GMRT) of each arm comparison in 340 mothers and 310 infants. Overall, 90% of mothers received folic acid supplements and 78% lived in Africa. At entry, median maternal age was 25 years, gestational age was 22 weeks, CD4 count was 482 cells/mm3 and log10HIV RNA was 3 copies/mL. Entry RBC-folate was similar across arms. Adj-GMRT of maternal folate was 3% higher in the DTG+FTC/TAF versus EFV/FTC/TDF arm (1.03, 95%CI 1.00, 1.06). The DTG+FTC/TAF arm had an 8% lower infant-maternal folate ratio (0.92, 95%CI 0.78, 1.09) versus EFV/FTC/TDF. Results are consistent with no clinically meaningful differences between arms for all RBC-folate outcomes and they suggest that cellular uptake of folate and folate transport to the infant do not differ in pregnant women starting DTG- vs. EFV-based ART. |
Antenatal care services in Benin and Tanzania 2021/2022: an equity analysis study

BMJ Public Health 2024 2 (1) INTRODUCTION: Antenatal care (ANC) interventions improve maternal and neonatal outcomes. However, access to ANC may be inequitable due to sociocultural, monetary and time factors. Examining drivers of ANC disparities may identify those amenable to policy change. METHODS: We conducted an ANC services equity analysis in selected public facilities in Geita, Tanzania, where most services are free to the end-user, and Atlantique, Benin, where every visit incurs user fees. Data on total ANC contacts, quality of care (QoC) indicators and wait times were collected from representative household surveys in the catchment of 40 clinics per country and were analysed by education and wealth. We used indices of inequality, concentration indices and Oaxaca-Blinder decompositions to determine the distribution, direction and magnitude of inequalities and their contributing factors. We assessed out-of-pocket expenses and the benefit incidence of government funding. RESULTS: ANC clients in both countries received less than the recommended minimum ANC contacts: 3.41 (95% CI 3.36 to 3.41) in Atlantique and 3.33 (95% CI 3.27 to 3.39) in Geita. Wealthier individuals had more ANC contacts than poorer ones at every education level in both countries; the wealthiest and most educated had two visits more than the poorest, least educated. In Atlantique, ANC attendees receive similar QoC regardless of socioeconomic status. In Geita, there are wide disparities in QoC received by education or wealth. In Atlantique, out-of-pocket expenses for the lowest wealth quintile are 2.7% of annual income compared with 0.8% for the highest, with user fees being the primary expense. In Geita, the values are 3.1% and 0.5%, respectively; transportation is the main expense. CONCLUSIONS: Inequalities in total ANC visits favouring wealthier, more educated individuals were apparent in both countries. In Atlantique, reduction of user-fees could improve ANC access. In Geita, training and equipping healthcare staff could improve QoC. Community health services could mitigate access barriers. |
Association between low maternal serum aflatoxin B1 exposure and adverse pregnancy outcomes in Mombasa, Kenya, 2017-2019: A nested matched case-control study

Matern Child Nutr 2024 e13688 We examined the association between serum aflatoxin B1-lysine adduct (AFB1-lys) levels in pregnant women and adverse pregnancy outcomes (low birthweight, miscarriage and stillbirth) through a nested matched case-control study of pregnant women enroled at ≤28 weeks' gestation in Mombasa, Kenya, from 2017 to 2019. Cases comprised women with an adverse birth outcome, defined as either delivery of a singleton infant weighing <2500 g, or a miscarriage, or a stillbirth, while controls were women who delivered a singleton live infant with a birthweight of ≥2500 g. Cases were matched to controls at a ratio of 1:2 based on maternal age at enrolment, gestational age at enrolment and study site. The primary exposure was serum AFB1-lys. The study included 125 cases and 250 controls. The median gestation age when serum samples were collected was 23.0 weeks (interquartile range [IQR]: 18.1-26.0) and 23.5 (IQR: 18.1-26.5) among cases and controls, respectively. Of the 375 tested sera, 145 (38.7%) had detectable serum AFB1-lys: 36.0% in cases and 40.0% in controls. AFB1-lys adduct levels were not associated with adverse birth outcomes on multivariable analysis. Mid-upper arm circumference was associated with a 6% lower odds of adverse birth outcome for every unit increase (p = 0.023). Two-fifths of pregnant women had detectable levels of aflatoxin midway through pregnancy. However, we did not detect an association with adverse pregnancy outcomes, likely because of low serum AFB1-lys levels and low power, restricting meaningful comparison. More research is needed to understand the public health risk of aflatoxin in pregnant women to unborn children. |
Child age at time of first maternal concern and time to services among children with autism spectrum disorder
Van Dyke J , Rosenberg SA , Crume T , Reyes N , Alexander AA , Barger B , Fitzgerald R , Hightshoe K , Moody EJ , Pazol K , Rosenberg CR , Rubenstein E , Wiggins L , DiGuiseppi C . J Dev Behav Pediatr 2024 OBJECTIVE: Early treatment of autism spectrum disorder (ASD) can improve developmental outcomes. Children with ASD from minority families often receive services later. We explored factors related to child's age at time of mother's first concerns about child's development and subsequent time to service initiation among children with ASD. METHODS: Analysis included 759 preschool-age children classified with ASD based on comprehensive evaluations. Factors associated with retrospectively reported child age at time of first maternal concern and subsequent time to service initiation were investigated using multiple linear regression and Cox proportional hazards. RESULTS: Earlier maternal concern was associated with multiparity, ≥1 child chronic condition, externalizing behaviors, and younger gestational age, but not race/ethnicity. Time to service initiation was longer for children of non-Latino Black or other than Black or White race and higher developmental level and shorter for children with ≥1 chronic condition and older child age at first maternal concern. CONCLUSION: Parity, gestational age, and child health and behavior were associated with child age at first maternal concern. Knowledge of child development in multiparous mothers may allow them to recognize potential concerns earlier, suggesting that first time parents may benefit from enhanced education about normal development. Race/ethnicity was not associated with child's age when mothers recognized potential developmental problems; hence, it is unlikely that awareness of ASD symptoms causes racial/ethnic disparities in initiation of services. Delays in time to service initiation among children from racial/ethnic minority groups highlight the need to improve their access to services as soon as developmental concerns are recognized. |
Women in coal mining-radiographic findings of women participants in the Coal Workers' Health Surveillance Program 1970-2022
Hall NB , Myers NT , Reynolds LE , Blackley DJ , Laney AS . J Womens Health (Larchmt) 2024 Objective: To describe the work experience and respiratory health of women coal miners in the United States using Coal Workers' Health Surveillance Program (CWHSP) data. Methods: Analysis included CWHSP participants with self-reported sex of female between January 1, 1970, and December 31, 2022, and examined radiographic surveillance, demographics, and job history. National Institute for Occupational Safety and Health-certified physicians classified chest radiographs. Results: Among 8,182 women participants, most worked <10 years and a majority reported working in non-dusty jobs. Among 3,392 with ≥1 year of coal mining tenure, 18 (0.5%) had evidence of pneumoconiosis, with no cases of progressive massive fibrosis. Conclusion: Women coal miners participating in the CWSHP had short mining careers and low pneumoconiosis prevalence. Few worked in the most dusty jobs, indicating limited exposure to coal mine dust. This underscores the need to explore women's roles in mining, and for improved gender-specific employment reporting. Such changes can enhance health and work conditions for women in male-dominated industries. |
Impact of malaria diagnostic choice on monitoring of Plasmodium falciparum prevalence estimates in the Democratic Republic of the Congo and relevance to control programs in high-burden countries

PLOS Glob Public Health 2023 3 (7) e0001375 Malaria programs rely upon a variety of diagnostic assays, including rapid diagnostic tests (RDTs), microscopy, polymerase chain reaction (PCR), and bead-based immunoassays (BBA), to monitor malaria prevalence and support control and elimination efforts. Data comparing these assays are limited, especially from high-burden countries like the Democratic Republic of the Congo (DRC). Using cross-sectional and routine data, we compared diagnostic performance and Plasmodium falciparum prevalence estimates across health areas of varying transmission intensity to illustrate the relevance of assay performance to malaria control programs. Data and samples were collected between March-June 2018 during a cross-sectional household survey across three health areas with low, moderate, and high transmission intensities within Kinshasa Province, DRC. Samples from 1,431 participants were evaluated using RDT, microscopy, PCR, and BBA. P. falciparum parasite prevalence varied between diagnostic methods across all health areas, with the highest prevalence estimates observed in Bu (57.4-72.4% across assays), followed by Kimpoko (32.6-53.2%), and Voix du Peuple (3.1-8.4%). Using latent class analysis to compare these diagnostic methods against an "alloyed gold standard," the most sensitive diagnostic method was BBA in Bu (high prevalence) and Voix du Peuple (low prevalence), while PCR diagnosis was most sensitive in Kimpoko (moderate prevalence). RDTs were consistently the most specific diagnostic method in all health areas. Among 9.0 million people residing in Kinshasa Province in 2018, the estimated P. falciparum prevalence by microscopy, PCR, and BBA were nearly double that of RDT. Comparison of malaria RDT, microscopy, PCR, and BBA results confirmed differences in sensitivity and specificity that varied by endemicity, with PCR and BBA performing best for detecting any P. falciparum infection. Prevalence estimates varied widely depending on assay type for parasite detection. Inherent differences in assay performance should be carefully considered when using community survey and surveillance data to guide policy decisions. |

Pre-pandemic landscape of the Oklahoma public health workforce: A case study from the Region 6 training needs assessment survey, 2019
Reinschmidt KM , Boyer S , Eberly K , Shorter CF , Dickens RD . J Public Health Manag Pract 2024 30 (4) E174-e183 CONTEXT: The COVID-19 pandemic highlighted the need for a well-trained public health workforce prior to the public health crisis. Public health training centers regularly assess workforce needs and their pre-pandemic data play vital roles in guiding public health workforce development beyond the crisis. PROGRAM: In 2019, Oklahoma partners of the Region 6 South Central Public Health Training Center (R6SCPHTC) co-conducted an online survey of the public health workforce located in the Health Resources & Services Administration Region 6. IMPLEMENTATION: Between March and April, the R6SCPHTC collected 503 surveys, including 201 surveys from Oklahoma. Questions inquired about demographic and workforce characteristics, work contexts, training needs and interests, training access and logistics, and knowledge of R6SCPHTC online resources. EVALUATION: Key findings included that two-thirds of the pre-pandemic Oklahoma public health workforce consisted of employees age 40 or older with few holding public health or medical degrees. The majority of respondents worked for health departments and Tribes, and almost half were frontline workers. Although at least half of the participants interested in training on public health activities and topics were familiar with them, confidence in their abilities related to these activities and topics was expressed by less than half. Qualitative data provided details on training needs addressed quantitatively and described new training areas. Survey participants expressed interest in diverse training delivery methods and technological devices. Most respondents were not familiar with the free trainings available through the R6SCPHTC. DISCUSSION: Similar to the regional and national public health workforce, Oklahoma's workforce needed training and support already before COVID-19. Time and resources need to be invested into the current and future workforce. While addressing priority public health skills and topics remains important, training on current and emerging topics is needed. Providing accessible trainings with expanded content will prepare Oklahoma's public health workforce for the future. |
Overdose, behavioral health services, and medications for opioid use disorder after a nonfatal overdose
Jones CM , Shoff C , Blanco C , Losby JL , Ling SM , Compton WM . JAMA Intern Med 2024 IMPORTANCE: Recognizing and providing services to individuals at highest risk for drug overdose are paramount to addressing the drug overdose crisis. OBJECTIVE: To examine receipt of medications for opioid use disorder (MOUD), naloxone, and behavioral health services in the 12 months after an index nonfatal drug overdose and the association between receipt of these interventions and fatal drug overdose. DESIGN, SETTING, AND PARTICIPANTS: This cohort study was conducted in the US from January 2020 to December 2021 using claims, demographic, mortality, and other data from the Centers for Medicare & Medicaid Services, the Centers for Disease Control and Prevention, and other sources. The cohort comprised Medicare fee-for-service beneficiaries aged 18 years or older with International Statistical Classification of Diseases, Tenth Revision, Clinical Modification codes for a nonfatal drug overdose. Data analysis was performed from February to November 2023. EXPOSURES: Demographic and clinical characteristics, substance use disorder, and psychiatric comorbidities. MAIN OUTCOMES AND MEASURES: Receipt of MOUD, naloxone, and behavioral health services as well as subsequent nonfatal and fatal drug overdoses. RESULTS: The cohort consisted of 136 762 Medicare beneficiaries (80 140 females [58.6%]; mean (SD) age of 68.2 [15.0] years) who experienced an index nonfatal drug overdose in 2020. The majority of individuals had Hispanic (5.8%), non-Hispanic Black (10.9%), and non-Hispanic White (78.8%) race and ethnicity and lived in metropolitan areas (78.9%). In the 12 months after their index nonfatal drug overdose, 23 815 beneficiaries (17.4%) experienced at least 1 subsequent nonfatal drug overdose and 1323 (1.0%) died of a fatal drug overdose. Opioids were involved in 72.2% of fatal drug overdoses. Among the cohort, 5556 (4.1%) received any MOUD and 8530 (6.2%) filled a naloxone prescription in the 12 months after the index nonfatal drug overdose. Filling a naloxone prescription (adjusted odds ratio [AOR], 0.70; 95% CI, 0.56-0.89), each percentage of days receiving methadone (AOR, 0.98; 95% CI, 0.98-0.99) or buprenorphine (AOR, 0.99; 95% CI, 0.98-0.99), and receiving behavioral health assessment or crisis services (AOR, 0.25; 95% CI, 0.22-0.28) were all associated with reduced adjusted odds of fatal drug overdose in the 12 months after the index nonfatal drug overdose. CONCLUSIONS AND RELEVANCE: This cohort study found that, despite their known association with reduced risk of a fatal drug overdose, only a small percentage of Medicare beneficiaries received MOUD or filled a naloxone prescription in the 12 months after a nonfatal drug overdose. Efforts to improve access to behavioral health services; MOUD; and overdose-prevention strategies, such as prescribing naloxone and linking individuals to community-based health care settings for ongoing care, are needed. |
Tobacco use among adults with disabilities in nine countries-Demographic and Health Survey, 2016-2021
Kress AC , Vashist A , Zhang QC , Dragicevic A , Njie GJ . PLOS Glob Public Health 2024 4 (6) e0003232 Few studies have investigated tobacco use among people with disabilities living in low- and middle-income countries (LMICs). We aimed to examine current tobacco use among men and women with disabilities using Demographic and Health Survey (DHS) data from 9 LMICs. We considered a respondent currently use tobacco products if they reported current use of any combustible/smoked tobacco products or smokeless tobacco products. We performed secondary analyses of DHS data from 2016-2021 collected in Haiti, Mali, Mauritania, Nigeria, Pakistan, Rwanda, South Africa, Timor-Leste, and Uganda. We examined marginal effects in logistic regression to calculate the adjusted prevalence and adjusted prevalence differences of tobacco use by disability status, controlling for selected sociodemographic characteristics. The adjusted prevalence of current use of tobacco products among women with a moderate/severe disability, mild disability, and no disability varied across countries, with medians of 1.9% (range = 0.1% [Mali] to 11.3% [Pakistan]), 3.2% (range = 0.9% [Nigeria] to 13.3% [South Africa]), and 2.3% (range = 0.5% [Nigeria] to 8.9% [South Africa]), respectively. For men with moderate/severe disability, the median adjusted prevalence for current use of tobacco products was 18.8% (range = 8.9% [Rwanda] to 55.0% [Timor-Leste]). The median prevalences of current use of tobacco products for men with mild disability and no disability were similar to those with moderate/severe disability, at 16.5% and 15.9%, respectively. Current tobacco product use among people with disabilities varied for countries included in our study; however, with few exceptions, current tobacco product use was similar across disability status groups. Additional research is warranted to determine whether our findings extend beyond the nine countries assessed here. It is important to consider the needs of people with disabilities in tobacco prevention, control, and cessation efforts so that this substantial population can benefit equitably from such programs, interventions, or policies. |
Exposure to anti- and pro-smoking messages among adults in China: Results from the Global Adult Tobacco Survey, 2018
Pei D , Popova L , Chowdhury P , Shi J , Njie G . PLoS One 2024 19 (6) e0304028 SIGNIFICANCE: For decades, tobacco advertisements and promotions have been common in mass media and public places in China. In 2015, China amended the Advertising Law to prohibit the distribution of tobacco advertising, while also initiating waves of tobacco control media campaigns. This study investigates the associations between exposure to anti- and pro-smoking messages, smoking status, and people's smoking-related beliefs and willingness to support tobacco control policies. METHODS: A secondary data analysis was performed with the 2018 Global Adult Tobacco Survey of 19,376 adults aged ≥15 years in China. Anti- and pro-smoking message exposures were measured as the sum of sources (media or places) where respondents have seen the messages. Multivariable logistic regression analyses were conducted to examine the relationships among smoking status, message exposure, and the outcome variables (health harm beliefs, support for increasing tax on cigarettes, support for using part of the increased tax on tobacco control) controlling for smoking status and demographic differences. RESULTS: Overall, 63.3% of the respondents reported being exposed to anti-smoking messages from at least 1 source, while 18.1% were exposed to pro-smoking messages from at least 1 source. Adults who currently, formerly, and never smoked differed in their beliefs about smoking and willingness to support tobacco control policies. Greater reported exposure to anti-smoking messages was positively associated with belief that smoking is harmful, support for increased cigarette tax, and support for using increased tax revenue for tobacco control measures. Meanwhile, greater reported exposure to pro-smoking messages was negatively related to willingness to support cigarette tax increases. CONCLUSIONS: While national and local tobacco control campaigns in China have reached a large proportion of the adult population, there is still room for improvement. China might consider expanding anti-tobacco campaigns, as reported exposure to these messages is associated with increased public awareness of the health hazards of smoking and support for increasing cigarette taxes. |

Wegman AD , Kalimuddin S , Marques ETA , Adams LE , Rothman AL , Gromowski GD , Wang TT , Weiskopf D , Hibberd ML , Alex Perkins T , Christofferson RC , Gunale B , Kulkarni PS , Rosas A , Macareo L , Yacoub S , Eong Ooi E , Paz-Bailey G , Thomas SJ , Waickman AT . Vaccine 2024 The first dengue "endgame" summit was held in Syracuse, NY over August 9 and 10, 2023. Organized and hosted by the Institute for Global Health and Translational Sciences at SUNY Upstate Medical University, the gathering brought together researchers, clinicians, drug and vaccine developers, government officials, and other key stakeholders in the dengue field for a highly collaborative and discussion-oriented event. The objective of the gathering was to discuss the current state of dengue around the world, what dengue "control" might look like, and what a potential roadmap might look like to achieve functional dengue control. Over the course of 7 sessions, speakers with a diverse array of expertise highlighted both current and historic challenges associated with dengue control, the state of dengue countermeasure development and deployment, as well as fundamental virologic, immunologic, and medical barriers to achieving dengue control. While sustained eradication of dengue was considered challenging, attendees were optimistic that significant reduction in the burden of dengue can be achieved by integration of vector control with effective application of therapeutics and vaccines. |
Detection of SARS-CoC-2 in a squirrel monkey (Saimiri sciureus): A One Health investigation and response
Yaglom HD , Roth A , Alvarez C , Corbus E , Ghai RR , Ferguson S , Ritter JM , Hecht G , Rekant S , Engelthaler DM , Venkat H , Tygielski S . J Zoo Wildl Med 2024 55 (2) 471-478 Through collaborative efforts, One Health partners have responded to outbreaks of COVID-19 among animals, including those in human care at zoos. Zoos have been faced with numerous challenges, including the susceptibility of many mammalian species, and therefore the need to heighten biosecurity measures rapidly. Robust One Health collaborations already exist in Arizona to address endemic and emerging zoonoses, but these have rarely included zoos. The pandemic shed light on this, and Arizona subsequently expanded its SARS-CoV-2 surveillance efforts to include zoo animals. Testing and epidemiologic support was provided to expedite the detection of and response to zoonotic SARS-CoV-2 infection in zoo animals, as well as to understand possible transmission events. Resulting from this program, SARS-CoV-2 was detected from a rectal swab collected from an 8-yr-old squirrel monkey (Saimiri sciureus) from a zoo in Southern Arizona. The animal had rapidly become ill with nonrespiratory symptoms and died in July 2022. Genomic sequencing from the swab revealed mutations consistent with the Omicron (BA.2) lineage. An epidemiologic investigation identified an animal caretaker in close proximity to the affected squirrel monkey who tested positive for COVID-19 the same day the squirrel monkey died. Critical One Health partners provided support to the zoo through engagement of local, state, and federal agencies. Necropsy and pathologic evaluation showed significant necrotizing colitis; the overall clinical and histopathological findings did not implicate SARS-CoV-2 infection alone as a causal or contributing factor in the squirrel monkey's illness and death. This report documents the first identification of SARS-CoV-2 in a squirrel monkey and highlights a successful and timely One Health investigation conducted through multisectoral collaboration. |
