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. |
Changes in vaccine hesitancy among parents of children aged 6 months - 17 Years, National Immunization Surveys, 2019-2022
Vashist K , Yankey D , Elam-Evans LD , Mu Y , Valier MR , Pingali C , Hill HA , Santibanez TA , Singleton JA . Vaccine 2024 BACKGROUND: Vaccine hesitancy (VH) has been a major contributor to large outbreaks of vaccine-preventable diseases globally, including in the United States. METHODS: Data from the 2019-2022 National Immunization Surveys were analyzed to assess parental hesitancy toward routine vaccination of their children aged 6 months -17 years. Joinpoint regression was employed to investigate trends in VH from 2019 to 2022 nationally overall and among socio-demographic subgroups. Using logistic regression, the difference between the prevalence of VH before and after the authorization of the COVID-19 vaccine for children aged 6 months-4 years, 5-11 years, and 12-17 years was computed. Both unadjusted and adjusted estimates were reported. VH was also compared within each socio-demographic subgroup with a reference level, at two-time points- before and after the authorization of the COVID-19 vaccine for each age group. RESULTS: Overall, VH remained around 19.0 % from Q2 2019 to Q3 2022. Parents of non-Hispanic Black children had the largest average quarterly decrease in VH (β = -0.55; p < 0.05 by test for trend). After the authorization of the COVID-19 vaccine for children aged 6 months to 4 years, the adjusted percentage of children having parents that reported VH decreased by 2.2 (95 % CI: -3.9, -0.6) percentage points (pp) from 21.6 % to 19.4 %. Conversely, for children aged 5-11 years, VH increased by 1.2 (95 % CI: 0.2, 2.3) pp, from 19.8 % to 21.0 %. VH among parents of non-Hispanic Black children decreased after the authorization of the COVID-19 vaccine for adolescents aged 12-17 years but remained significantly higher compared to parents of non-Hispanic White children before and after authorization of the COVID-19 vaccine for all age groups. DISCUSSION: About 1 in 5 children had parents reporting VH from 2019 to 2022. Parental VH increased after the authorization of the COVID-19 vaccine for children aged 5-11 years and declined for children aged 6 months-4 years. |
Lower total cholesterol and triglyceride levels in ankylosing spondylitis than non-inflammatory rheumatic disease controls in a 1978-98 study: a potential effect of increased physical energetics in manual occupations in the pre-2000 chronologic era
Masi AT , Mohan PC , Murugan T , Evans CR , Ryan MJ , Brezka ML , Hanna V , Cooper GR , Aldag JC . Clin Exp Rheumatol 2024 OBJECTIVES: No article on serum lipids in ankylosing spondylitis (AS) and control subjects has been reported from USA. The primary aim of this study was to determine if any difference occurred in serum lipid levels in AS and control rheumatic disorders in two time periods, 1978-98 and 2000-10. The secondary aim was to investigate variables associated with lipid levels and if a difference was found between AS and control disorders. METHODS: The AS patients were compared to non-inflammatory rheumatic disorders (NIRDs) in 1978-98 and 2000-10 surveys and to rheumatoid arthritis (RA) in the 2000-10 survey. Patients were matched within 5 years of age, sex, and clinic or hospital source. RESULTS: In the 1978-98 survey, entry mean (SEM) serum cholesterol level [mg/dL] was highly (p<0.001) significantly lower in 69 AS [179.0 (4.8)] than 69 matched NIRD controls [208.0 (5.6)]. In 29 pairs of AS and NIRD subjects having manual labour occupations, mean (SEM) cholesterol level was additionally lower in AS [156.7 (5.9)] and higher in 29 NIRD controls [213.3 (8.6)] (p<0.001). In manual labour workers, mean (SEM) serum triglyceride was significantly lower (p=0.004) in 15 AS [110.3 (14.1)] than 14 NIRD controls [185.2 (19.3)]. In the 2000-10 survey, no lipid difference was found between AS vs. NIRD control patients. CONCLUSIONS: In the 1978-98 survey, AS had significantly lower mean serum cholesterol and triglyceride levels than NIRD control patients. Associated manual labour occupations may have significantly contributed to results, possibly related to increased energy expenditures from physical activity in the pre-2000 era. |

Gussin GM , McKinnell JA , Singh RD , Miller LG , Kleinman K , Saavedra R , Tjoa T , Gohil SK , Catuna TD , Heim LT , Chang J , Estevez M , He J , O'Donnell K , Zahn M , Lee E , Berman C , Nguyen J , Agrawal S , Ashbaugh I , Nedelcu C , Robinson PA , Tam S , Park S , Evans KD , Shimabukuro JA , Lee BY , Fonda E , Jernigan JA , Slayton RB , Stone ND , Janssen L , Weinstein RA , Hayden MK , Lin MY , Peterson EM , Bittencourt CE , Huang SS . Jama 2024 IMPORTANCE: Infections due to multidrug-resistant organisms (MDROs) are associated with increased morbidity, mortality, length of hospitalization, and health care costs. Regional interventions may be advantageous in mitigating MDROs and associated infections. OBJECTIVE: To evaluate whether implementation of a decolonization collaborative is associated with reduced regional MDRO prevalence, incident clinical cultures, infection-related hospitalizations, costs, and deaths. DESIGN, SETTING, AND PARTICIPANTS: This quality improvement study was conducted from July 1, 2017, to July 31, 2019, across 35 health care facilities in Orange County, California. EXPOSURES: Chlorhexidine bathing and nasal iodophor antisepsis for residents in long-term care and hospitalized patients in contact precautions (CP). MAIN OUTCOMES AND MEASURES: Baseline and end of intervention MDRO point prevalence among participating facilities; incident MDRO (nonscreening) clinical cultures among participating and nonparticipating facilities; and infection-related hospitalizations and associated costs and deaths among residents in participating and nonparticipating nursing homes (NHs). RESULTS: Thirty-five facilities (16 hospitals, 16 NHs, 3 long-term acute care hospitals [LTACHs]) adopted the intervention. Comparing decolonization with baseline periods among participating facilities, the mean (SD) MDRO prevalence decreased from 63.9% (12.2%) to 49.9% (11.3%) among NHs, from 80.0% (7.2%) to 53.3% (13.3%) among LTACHs (odds ratio [OR] for NHs and LTACHs, 0.48; 95% CI, 0.40-0.57), and from 64.1% (8.5%) to 55.4% (13.8%) (OR, 0.75; 95% CI, 0.60-0.93) among hospitalized patients in CP. When comparing decolonization with baseline among NHs, the mean (SD) monthly incident MDRO clinical cultures changed from 2.7 (1.9) to 1.7 (1.1) among participating NHs, from 1.7 (1.4) to 1.5 (1.1) among nonparticipating NHs (group × period interaction reduction, 30.4%; 95% CI, 16.4%-42.1%), from 25.5 (18.6) to 25.0 (15.9) among participating hospitals, from 12.5 (10.1) to 14.3 (10.2) among nonparticipating hospitals (group × period interaction reduction, 12.9%; 95% CI, 3.3%-21.5%), and from 14.8 (8.6) to 8.2 (6.1) among LTACHs (all facilities participating; 22.5% reduction; 95% CI, 4.4%-37.1%). For NHs, the rate of infection-related hospitalizations per 1000 resident-days changed from 2.31 during baseline to 1.94 during intervention among participating NHs, and from 1.90 to 2.03 among nonparticipating NHs (group × period interaction reduction, 26.7%; 95% CI, 19.0%-34.5%). Associated hospitalization costs per 1000 resident-days changed from $64 651 to $55 149 among participating NHs and from $55 151 to $59 327 among nonparticipating NHs (group × period interaction reduction, 26.8%; 95% CI, 26.7%-26.9%). Associated hospitalization deaths per 1000 resident-days changed from 0.29 to 0.25 among participating NHs and from 0.23 to 0.24 among nonparticipating NHs (group × period interaction reduction, 23.7%; 95% CI, 4.5%-43.0%). CONCLUSIONS AND RELEVANCE: A regional collaborative involving universal decolonization in long-term care facilities and targeted decolonization among hospital patients in CP was associated with lower MDRO carriage, infections, hospitalizations, costs, and deaths. |
Investigation of an mpox outbreak affecting many vaccinated persons in Chicago, IL-March 2023-June 2023
Faherty EAG , Holly T , Ogale YP , Spencer H , Becht AM , Crisler G , Wasz M , Stonehouse P , Barbian HJ , Zelinski C , Kittner A , Foulkes D , Anderson KW , Evans T , Nicolae L , Staton A , Hardnett C , Townsend MB , Carson WC , Panayampalli SS , Hutson CL , Gigante CM , Quilter LAS , Gorman S , Borah B , Black SR , Pacilli M , Kern D , Kerins J , McCollum AM , Rao AK , Tabidze I . Clin Infect Dis 2024 BACKGROUND: After months of few mpox cases, an increased number of cases were reported in Chicago during May 2023; predominantly among fully vaccinated patients. We investigated the outbreak scope, differences between vaccinated and unvaccinated patients, and hypotheses for monkeypox virus (MPXV) infection after vaccination. METHODS: We interviewed patients and reviewed medical records to assess demographic, behavioral, and clinical characteristics, mpox vaccine status, and vaccine administration routes. We evaluated serum antibody levels after infection and compared patient viral genomes with MPXV sequences in available databases. We discussed potential vaccine compromise with partners who manufactured, handled, and administered vaccine associated with breakthrough infections. RESULTS: During March 18-June 27, 2023, we identified 49 mpox cases; 57% of these mpox patients were fully vaccinated (FV). FV patients received both JYNNEOS doses subcutaneously (57%), intradermally (7%), or via heterologous administration (36%). FV patients had more median sex partners (3, IQR=1-4) versus not fully vaccinated (NFV) patients (1, IQR=1-2). Thirty-six of 37 sequenced specimens belonged to lineage B.1.20 of clade IIb MPXV, which did not demonstrate any amino acid changes relative to B.1, the predominant lineage from May 2022. Vaccinated patients demonstrated expected humoral antibody responses; none were hospitalized. No vaccine storage excursions were identified. Approximately 63% of people at risk for mpox in Chicago were FV during this period. CONCLUSIONS: Our investigation indicated cases were likely due to frequent behaviors associated with mpox transmission, even with relatively high vaccine effectiveness and vaccine coverage. Cases after vaccination might occur in similar populations. |
Factors associated with the awareness of and willingness to use HIV pre-exposure prophylaxis among gay, bisexual, and other men who have sex with men, Baltimore, MD, 2017-2019
King H , Thornton N , Evans KN , Tadfor Y , German D , Flynn C , Jennings J , Fields EL . J Racial Ethn Health Disparities 2024 Pre-exposure prophylaxis (PrEP) is an effective tool in protecting persons from acquiring HIV infection through sex or injection drug use. However, awareness and willingness to use PrEP among Black gay, bisexual, and other men who have sex with men (BMSM) remain suboptimal compared to White MSM (WMSM) in the United States. Our aims were to (1) assess the factors associated with PrEP awareness and willingness to use PrEP among MSM and (2) compare the PrEP perceptions among BMSM versus non-Black MSM. Data were drawn from two cross-sectional behavioral surveys in Baltimore, MD: Behavioral Surveillance Research (BESURE) conducted in 2017, and Safe Spaces 4 Sexual Health (SS4SH), conducted in 2018 and 2019. Descriptive statistics were used to summarize the study population. We used Poisson regression models to identify variables associated with awareness of PrEP and willingness to use PrEP. PrEP perceptions were assessed via 13 items scored on a 5-point Likert scale. Finally, we conducted a post-hoc exploratory bivariate analysis of the relationship between PrEP perception and willingness to use PrEP, stratified by race/ethnicity. A total of 261 MSM participated in this study. Many of the participants were aware of PrEP (75.1%). Factors associated with greater PrEP awareness included having greater than a high school education (aRR 1.22, 95% CI 1.04, 1.43); and earning more than $25,000 annually (aRR 1.24, 95% CI 1.08, 1.42). Participants who had received money in exchange for sex one or more times were less likely to be aware of PrEP (aRR 0.59, 95% CI 0.36, 0.95). More than half of the participants were willing to use PrEP (55.3%). In bivariate and multivariable analyses, demographic or behavioral characteristics were not significantly associated with willingness to use PrEP. Higher agreement with the following statements was associated with lower willingness to use PrEP: "Having to take a pill every day is difficult" (RR 0.89, 95% CI 0.82-0.97) and, "I am concerned about the side effects of PrEP" (RR 0.89, 95% CI 0.82-0.96), and "PrEP is for people who have riskier sex lives than I do" (RR 0.86, 95% CI 0.78-0.95). Conversely, higher willingness to use PrEP was associated with comfortable having sex without a condom (RR 1.11, 95% CI 1.02-1.21), less anxious about sex (RR 1.12, 95% CI 1.02-1.24), and my friends think that I should take PrEP (RR 1.19, 95% CI 1.07-1.32). We found BMSM compared to non-Black MSM had higher mean scores related to taking a daily pill (p = 0.041), concerns about side effects (p = 0.012), concerns about people thinking they had HIV (p = 0.001), concerns about the financial costs of PrEP (p = 0.038) and caution when dealing with healthcare organizations/medical mistrust (p = 0.019). Perceptions with a statistically significant lower score among BMSM versus non-Black MSM included statements such as, comfortable having sex without a condom (p = 0.003) and less anxious about sex (p < 0.001). We conclude HIV prevention strategies, programs, and interventions should be cognizant of PrEP perceptions that facilitate or hinder PrEP uptake in Baltimore City, MD. |

Changes in the seroprevalence of tick-borne rickettsia and ehrlichia among soldiers-Fort Liberty, North Carolina, 1991-2019
Rockwell EM , Abernathy HA , Evans LM , Bhowmik R , Giandomenico DA , Salzer JS , Maldonado CJ , Choi YS , Boyce RM . J Infect Dis 2024 We obtained samples from the Department of Defense Serum Repository from soldiers who were stationed at Fort Liberty, North Carolina, between 1991 and 2019 to assess temporal trends in tick-borne rickettsiosis and ehrlichiosis. Serological evidence of infection was common, with nearly 1 in 5 (18.9%) demonstrating antibodies. We observed significant decreases in Rickettsia seroprevalence (adjusted odds ratio [aOR], 0.42 [95% CI, .27-.65], P = .0001) while over the same period Ehrlichia seroprevalence, albeit less common, nearly doubled (aOR, 3.61 [95% CI, 1.10-13.99], P = .048). The increase in Ehrlichia seroprevalence likely reflects increased transmission resulting from the expanding geographic range of the lone star tick. |
Using trust-based philanthropy with community-based organizations during the COVID-19 pandemic
Powell Rachel , Evans Dorothy , Bednar Hailey , Oladipupo Brittany , Sidibe Turquoise . Journal of Philanthropy and Marketing 2023 n/a e1786 Abstract Community-based organizations (CBOs) fill a critical role in acting as public health partners and trusted resources for their communities, especially in an emergency. The CDC Foundation, an independent, nonprofit organization, used trust-based philanthropy to manage more than 110 COVID-19 grants focused on equitable vaccine information, outreach, and access. The CDC Foundation team uses a trust-based philanthropy paradigm by applying five out of six of the grantmaking practices: do the homework; simplify and streamline paperwork; be transparent and responsive; solicit and act on feedback; and offer support beyond the check. By applying trust-based philanthropy practices, the CDC Foundation is empowering CBOs through flexible grant management and more equitable power dynamics as grantee and grantor. This has been essential to CBOs in their efforts of tackling health inequities during the COVID-19 pandemic and improving community resilience. Lessons learned will inform future collaborations with CBOs where the power dynamics are shared. |
The medications for opioid use disorder study: Methods and initial outcomes from an 18-month study of patients in treatment for opioid use disorder
Dever JA , Hertz MF , Dunlap LJ , Richardson JS , Wolicki SB , Biggers BB , Edlund MJ , Bohm MK , Turcios D , Jiang X , Zhou H , Evans ME , Guy GP Jr . Public Health Rep 2024 333549231222479 OBJECTIVE: Opioid use disorder (OUD) affects approximately 5.6 million people in the United States annually, yet rates of the use of effective medication for OUD (MOUD) treatment are low. We conducted an observational cohort study from August 2017 through May 2021, the MOUD Study, to better understand treatment engagement and factors that may influence treatment experiences and outcomes. In this article, we describe the study design, data collected, and treatment outcomes. METHODS: We recruited adult patients receiving OUD treatment at US outpatient facilities for the MOUD Study. We collected patient-level data at 5 time points (baseline to 18 months) via self-administered questionnaires and health record data. We collected facility-level data via questionnaires administered to facility directors at 2 time points. Across 16 states, 62 OUD treatment facilities participated, and 1974 patients enrolled in the study. We summarized descriptive data on the characteristics of patients and OUD treatment facilities and selected treatment outcomes. RESULTS: Approximately half of the 62 facilities were private, nonprofit organizations; 62% focused primarily on substance use treatment; and 20% also offered mental health services. Most participants were receiving methadone (61%) or buprenorphine (32%) and were predominately non-Hispanic White (68%), aged 25-44 years (62%), and female (54%). Compared with patient-reported estimates at baseline, 18-month estimates suggested that rates of abstinence increased (55% to 77%), and rates of opioid-related overdoses (7% to 2%), emergency department visits (9% to 4%), and arrests (15% to 7%) decreased. CONCLUSIONS: Our results demonstrated the benefits of treatment retention not only on abstinence from opioid use but also on other quality-of-life metrics, with data collected during an extended period. The MOUD Study produced rich, multilevel data that can lay the foundation for an evidence base to inform OUD treatment and support improvement of care and patient outcomes. |
Estimating county-level vaccination coverage using small area estimation with the National Immunization Survey-Child
Seeskin ZH , Ganesh N , Maitra P , Herman P , Wolter KM , Copeland KR , English N , Chen MP , Singleton JA , Santibanez TA , Yankey D , Elam-Evans LD , Sterrett N , Smith CS , Gipson K , Meador S . Vaccine 2023 The National Immunization Survey-Child (NIS-Child) provides annual vaccination coverage estimates in the United States for children aged 19 through 35 months, nationally, for each state, and for select local areas and territories. There is a need for vaccination coverage estimates for smaller geographic areas to support local authority planning and identify counties with potentially low vaccination coverage for possible further intervention. We describe small area estimation methods using 2008-2018 NIS-Child data to generate county-level estimates for children up to two years of age born 2007-2011 and 2012-2016. We applied an empirical best linear unbiased prediction method to combine direct estimates of vaccination coverage with model-based prediction using county-level predictors regarding health and demographic characteristics. We review the predictors commonly selected for the small area models and note multiple predictors related to barriers to vaccination. |
Prevalence and mean number of teeth with amalgam and nonamalgam restorations, United States, 2015 through 2018
Beltrán-Aguilar ED , Thornton-Evans G , Wei L , Bernal J . J Am Dent Assoc 2023 154 (5) 417-426 BACKGROUND: Amalgam has been used for more than 150 years as a safe and reliable restorative material. The authors described the occurrence of amalgam and nonamalgam restorations in the United States in primary and permanent teeth across age groups and according to sociodemographic characteristics. METHODS: The authors used clinical examination data from the National Health and Nutrition Examination Survey 2015-2018 for participants 2 years and older (n = 17,040). The authors estimated the prevalence and mean number of amalgam and nonamalgam restorations in primary and permanent teeth according to age groups (2-5 years, 6-11 years, 12-15 years, 16-19 years, 20-39 years, 40-59 years, 60-79 years, and ≥ 80 years), race and ethnicity, federal poverty guideline, education, and pregnancy status. RESULTS: The prevalence of amalgam restorations ranged from 4% through 69%. Overall, amalgam restorations were more prevalent in children and adolescents from racial and ethnic minority groups and families at lower poverty levels and with lower education. The mean number of teeth with nonamalgam restorations was higher than those with amalgam restorations in primary teeth of children aged 6 through 11 years, permanent teeth of those 12 through 15 years and 20 through 39 years, and women aged 20 through 49 years, regardless of pregnancy status. The mean number of amalgam restorations was higher than that for nonamalgam restorations in older age groups. CONCLUSIONS: Nonamalgam restorations were the most common in the primary teeth of children older than 5 years and in the permanent teeth of adults younger than 40 years. Amalgam restorations were more common in older adults. Amalgam and nonamalgam restorations were equally common in children younger than 5 years. PRACTICAL IMPLICATIONS: The study findings suggest a shift from amalgam to alternative restorative materials in the United States. |
Advancing data capacity for economic outcomes in patient-centered outcomes research: Challenges and opportunities
Timbie JW , Reynolds KA , Evans EL , Brown DS , Cohen JW , Darien G , DeVoe JE , Grosse SD , Holve E , Meltzer DO , Merritt JG , Neumann PJ , Yabroff KR , Smith SR . Med Care 2023 61 S161-s165 The economic impacts of health care treatments and services on individuals and their families are central to many decisions people make about the use of health care. However, without the high-quality data needed to generate evidence on the clinical effectiveness and economic impacts of an intervention, decision-makers are generally limited in their ability to make informed health care decisions that reflect patient values and preferences. The importance of evidence on economic impacts, including nonmedical costs and work-related impacts, was recognized in the reauthorization of the Patient-centered Outcomes Research Trust Fund,1 which added economic outcomes to the range of outcomes that should be considered as part of patient-centered outcomes research (PCOR). |
Vaccination coverage by age 24 months among children born in 2019 and 2020 - National Immunization Survey-Child, United States, 2020-2022
Hill HA , Yankey D , Elam-Evans LD , Chen M , Singleton JA . MMWR Morb Mortal Wkly Rep 2023 72 (44) 1190-1196 National Immunization Survey-Child data collected in 2022 were combined with data from previous years to assemble birth cohorts and assess coverage with routine vaccines by age 24 months by birth cohort. Overall, vaccination coverage was similar among children born during 2019-2020 compared with children born during 2017-2018, except that coverage with both the birth dose of hepatitis B vaccine and ≥1 dose of hepatitis A vaccine increased. Coverage was generally higher among non-Hispanic White (White) children (2-21 percentage points higher than coverage for non-Hispanic Black or African American, Hispanic or Latino, and non-Hispanic American Indian/Alaska Native [AI/AN] children), children living at or above poverty (3.5-22 percentage points higher than coverage for children living below the federal poverty level), privately insured children (2.4-38 percentage points higher than coverage for children with Medicaid, other insurance, or no insurance), and children in urban areas (3-16.5 percentage points higher than coverage for children living in rural areas). Coverage with the full series of Haemophilus influenzae type b conjugate vaccine was lower among AI/AN children compared with White children. Trends in vaccination coverage disparities across categories of race and ethnicity, health insurance status, poverty status, and urbanicity were evaluated for the 2016-2020 birth cohorts. Fewer than 5% of 168 trends examined were statistically significant, including six increases (widening of the coverage gap) and one decrease (narrowing of the gap). Analyses revealed a widening of the gap between children living at or above the poverty level (higher coverage) and those living below poverty (lower coverage), for several vaccines. Socioeconomic, demographic, and geographic disparities in vaccination coverage persist; addressing them is important to ensure protection for all children against vaccine-preventable disease. |
Importance of public and private partnership supporting data disaggregation to measure racial, sexual orientation, and gender identity disparities in COVID-19
Powell R , Parker B , Moore M , Xiong T , Evans D , Sidibe T . Health Secur 2023 21 S35-s41 The COVID-19 pandemic has exposed shortcomings in the US public health data system infrastructure, including incomplete or disparate processes related to data collection, management, sharing, and analysis. Public health data modernization is critical to ensure health equity is at the core of preparedness and response efforts and policies that prioritize equitable responses to health emergencies. To address the inequitable uptake and distribution of COVID-19 vaccinations in communities most disproportionately impacted by the pandemic, the CDC Foundation's Response Crisis and Preparedness Unit began partnering with community-based organizations in March 2021 to provide education and outreach and facilitate access to vaccines. These organizations engaged with partners and communities to address vaccine-related concerns, develop innovative and culturally appropriate communication strategies, and promote timely vaccination. Two grantees, Out Boulder County in Colorado and the Coalition of Asian American Leaders in Minnesota, experienced issues related to public health data collection standards and practices for COVID-19. Data collection tools often lack the appropriate or necessary demographic variables or level of disaggregation needed to be able to assess prioritization and disparities within racial and ethnic groups and across sexual orientation and gender identity categories. In this case study, both grantee organizations document their experiences, challenges, and strategies to overcome barriers to implementing their projects resulting from a lack of meaningful data. These examples identify inequities and systems-level changes related to data collection and surveillance, and they provide recommendations and lessons learned to improve data surveillance for more equitable public health responses. |
A population-based study of the utility of screening for tics and the relative contribution of tics and psychiatric comorbidity to academic and social impairment in adolescents
Smith JN , Owens JS , Evans SW , Bitsko RH , Holbrook JR . Evid Based Pract Child Adolesc Ment Health 2023 This study examined the performance of a brief screening tool for tics in adolescents. Academic and social impairment in students by tic screen status and emotional/behavioral problem status were examined. Data were collected as part of an epidemiologic study, the Project to Learn about Youth–Mental Health. Participants were 2,312 secondary school students at the Ohio site (47.4% female; 94.4% non-Hispanic white) and their teachers. Students completed 6 items from the Motor tic, Obsessions and compulsions, Vocal tic Evaluation Survey (MOVES-6) and the Strengths and Difficulties Questionnaire (SDQ). Teachers completed the Proxy Report Questionnaire for tics and SDQ. Based on responses to the MOVES-6, 11.1% of students screened positive for tics. Internal consistency was adequate (α = 0.76); inter-rater consistency between teachers and students was low (0.03). Based on student self-report, those who screened positive for tics self-reported more academic and social impairment than students who screened negative for tics; teacher-report of impairment was similar between those with a positive or negative tic screen. Students who screened positive for tics and reported internalizing difficulties reported more academic and social impairment than students with only a positive tic screen. Teachers perceived those screening positive for tics and externalizing difficulties as the most socially impaired. In conclusion, a positive self-reported tic screen was associated with self-reported academic and social impairment.

N Engl J Med 2023 389 (19) 1766-1777 BACKGROUND: Nursing home residents are at high risk for infection, hospitalization, and colonization with multidrug-resistant organisms. METHODS: We performed a cluster-randomized trial of universal decolonization as compared with routine-care bathing in nursing homes. The trial included an 18-month baseline period and an 18-month intervention period. Decolonization entailed the use of chlorhexidine for all routine bathing and showering and administration of nasal povidone-iodine twice daily for the first 5 days after admission and then twice daily for 5 days every other week. The primary outcome was transfer to a hospital due to infection. The secondary outcome was transfer to a hospital for any reason. An intention-to-treat (as-assigned) difference-in-differences analysis was performed for each outcome with the use of generalized linear mixed models to compare the intervention period with the baseline period across trial groups. RESULTS: Data were obtained from 28 nursing homes with a total of 28,956 residents. Among the transfers to a hospital in the routine-care group, 62.2% (the mean across facilities) were due to infection during the baseline period and 62.6% were due to infection during the intervention period (risk ratio, 1.00; 95% confidence interval [CI], 0.96 to 1.04). The corresponding values in the decolonization group were 62.9% and 52.2% (risk ratio, 0.83; 95% CI, 0.79 to 0.88), for a difference in risk ratio, as compared with routine care, of 16.6% (95% CI, 11.0 to 21.8; P<0.001). Among the discharges from the nursing home in the routine-care group, transfer to a hospital for any reason accounted for 36.6% during the baseline period and for 39.2% during the intervention period (risk ratio, 1.08; 95% CI, 1.04 to 1.12). The corresponding values in the decolonization group were 35.5% and 32.4% (risk ratio, 0.92; 95% CI, 0.88 to 0.96), for a difference in risk ratio, as compared with routine care, of 14.6% (95% CI, 9.7 to 19.2). The number needed to treat was 9.7 to prevent one infection-related hospitalization and 8.9 to prevent one hospitalization for any reason. CONCLUSIONS: In nursing homes, universal decolonization with chlorhexidine and nasal iodophor led to a significantly lower risk of transfer to a hospital due to infection than routine care.

Pruitt Evans S , Ailes EC , Kramer MR , Shumate CJ , Reefhuis J , Insaf TZ , Yazdy MM , Carmichael SL , Romitti PA , Feldkamp ML , Neo DT , Nembhard WN , Shaw GM , Palmi E , Gilboa SM . Epidemiology 2023 34 (6) 774-785 BACKGROUND: Individual measures of socioeconomic status (SES) have been associated with an increased risk of neural tube defects (NTDs); however, the association between neighborhood SES and NTD risk is unknown. Using data from the National Birth Defects Prevention Study (NBDPS) from 1997 to 2011, we investigated the association between measures of census tract SES and NTD risk. METHODS: The study population included 10,028 controls and 1829 NTD cases. We linked maternal addresses to census tract SES measures and used these measures to calculate the neighborhood deprivation index. We used generalized estimating equations to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) estimating the impact of quartiles of census tract deprivation on NTDs adjusting for maternal race-ethnicity, maternal education, and maternal age at delivery. RESULTS: Quartiles of higher neighborhood deprivation were associated with NTDs when compared with the least deprived quartile (Q2: aOR = 1.2; 95% CI = 1.0, 1.4; Q3: aOR = 1.3, 95% CI = 1.1, 1.5; Q4 (highest): aOR = 1.2; 95% CI = 1.0, 1.4). Results for spina bifida were similar; however, estimates for anencephaly and encephalocele were attenuated. Associations differed by maternal race-ethnicity. CONCLUSIONS: Our findings suggest that residing in a census tract with more socioeconomic deprivation is associated with an increased risk for NTDs, specifically spina bifida. |
Vaccination coverage among adolescents aged 13-17 years - National Immunization Survey-Teen, United States, 2022
Pingali C , Yankey D , Elam-Evans LD , Markowitz LE , Valier MR , Fredua B , Crowe SJ , DeSisto CL , Stokley S , Singleton JA . MMWR Morb Mortal Wkly Rep 2023 72 (34) 912-919 Three vaccines are routinely recommended for adolescents to prevent pertussis, meningococcal disease, and cancers caused by human papillomavirus (HPV). CDC analyzed data from the 2022 National Immunization Survey-Teen for 16,043 adolescents aged 13-17 years to assess vaccination coverage. Birth cohort analyses were conducted to assess trends in vaccination coverage by age 13 years (i.e., before the 13th birthday) and by age 14 years (i.e., before the 14th birthday) among adolescents who were due for routine vaccination before and during the COVID-19 pandemic. Cross-sectional analysis was used to assess coverage estimates among adolescents aged 13-17 years. In 2022, vaccination coverage by age 14 years among adolescents born in 2008 continued to lag that of earlier birth cohorts and varied by sociodemographic factors and access to health care compared with coverage among earlier birth cohorts. Vaccination coverage by age 13 years among adolescents born in 2009 was similar to coverage estimates obtained before the COVID-19 pandemic. Among all adolescents aged 13-17 years, 2022 vaccination coverage levels did not differ from 2021 levels; however, initiation of the HPV vaccination series decreased among those who were insured by Medicaid. Coverage with ≥1 dose of tetanus, diphtheria, and acellular pertussis vaccine and ≥1 dose meningococcal conjugate vaccine was high and stable (around 90%). Providers should review adolescent vaccination records, especially among those born in 2008 and those in populations eligible for the Vaccines for Children program, to ensure adolescents are up to date with all recommended vaccines. |
Survey of invasive mosquito surveillance and control capacity in Southeastern USA reveals training and resource needs

J Am Mosq Control Assoc 2023 39 (2) 108-121 Several invasive mosquito species that are nuisances or of medical and veterinary importance have been introduced into the Southeastern region of the USA, posing a threat to other species and the local ecosystems and/or increasing the risk of pathogen transmission to people, livestock, and domestic pets. Prompt and effective monitoring and control of invasive species is essential to prevent them from spreading and causing harmful effects. However, the capacity for invasive mosquito species surveillance is highly variable among mosquito control programs in the Southeast, depending on a combination of factors such as regional geography and climate, access to resources, and the ability to interact with other programs. To facilitate the development of invasive mosquito surveillance in the region, we, the Mosquito BEACONS (Biodiversity Enhancement and Control of Non-native Species) working group, conducted a survey on the capacities of various public health agencies and pest control agencies engaged in mosquito surveillance and control in seven Southeastern states (Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina). Ninety control programs completed the survey, representing an overall response rate of 25.8%. We report key findings from our survey, emphasizing the training and resource needs, and discuss their implications for future invasive mosquito surveillance and control capacity building. By increasing communication and collaboration opportunities (e.g., real-time sharing of collection records, coordinated multistate programs), the establishment of Mosquito BEACONS and the implementation of this survey can accelerate knowledge transfer and improve decision support capacity in response to or in preparation for invasive mosquito surveillance and can establish infrastructure that can be used to inform programs around the world. |
Addressing Personal Protective Equipment (PPE) Decontamination: Methylene Blue and Light Inactivates SARS-CoV-2 on N95 Respirators and Masks with Maintenance of Integrity and Fit (preprint)

These shortages underscore the urgent need for simple, efficient, and inexpensive methods to decontaminate SARS-CoV-2-exposed PPE enabling safe reuse of masks and respirators. Efficient decontamination must be available not only in low-resourced settings, but also in well-resourced settings affected by PPE shortages. Methylene blue (MB) photochemical treatment, hitherto with many clinical applications including those used to inactivate virus in plasma, presents a novel approach for widely applicable PPE decontamination. Dry heat (DH) treatment is another potential low-cost decontamination method.Methods MB and light (MBL) and DH treatments were used to inactivate coronavirus on respirator and mask material. We tested three N95 filtering facepiece respirators (FFRs), two medical masks (MMs), and one cloth community mask (CM). FFR/MM/CM materials were inoculated with SARS-CoV-2 (a Betacoronavirus), murine hepatitis virus (MHV) (a Betacoronavirus), or porcine respiratory coronavirus (PRCV) (an Alphacoronavirus), and treated with 10 µM MB followed by 50,000 lux of broad-spectrum light or 12,500 lux of red light for 30 minutes, or with 75°C DH for 60 minutes. In parallel, we tested respirator and mask integrity using several standard methods and compared to the FDA-authorized vaporized hydrogen peroxide plus ozone (VHP+O3) decontamination method. Intact FFRs/MMs/CM were subjected to five cycles of decontamination (5CD) to assess integrity using International Standardization Organization (ISO), American Society for Testing and Materials (ASTM) International, National Institute for Occupational Safety and Health (NIOSH), and Occupational Safety and Health Administration (OSHA) test methods.Findings Overall, MBL robustly and consistently inactivated all three coronaviruses with at least a 4-log reduction. DH yielded similar results, with the exception of MHV, which was only reduced by 2-log after treatment. FFR/MM integrity was maintained for 5 cycles of MBL or DH treatment, whereas one FFR failed after 5 cycles of VHP+O3. Baseline performance for the CM was variable, but reduction of integrity was minimal.Interpretation Methylene blue with light and DH treatment decontaminated masks and respirators by inactivating three tested coronaviruses without compromising integrity through 5CD. MBL decontamination of masks is effective, low-cost and does not require specialized equipment, making it applicable in all-resource settings. These attractive features support the utilization and continued development of this novel PPE decontamination method.Competing Interest StatementAuthors Thomas S.

We investigated whether bacterial respiratory infections and viral load were associated with poor clinical outcome and host immune tone. We obtained bacterial and fungal culture data from 589 critically ill subjects with COVID-19 requiring mechanical ventilation. On a subset of the subjects that underwent bronchoscopy, we also quantified SARS-CoV-2 viral load, analyzed the microbiome of the lower airways by metagenome and metatranscriptome analyses and profiled the host immune response. We found that isolation of a hospital-acquired respiratory pathogen was not associated with fatal outcome. However, poor clinical outcome was associated with enrichment of the lower airway microbiota with an oral commensal ( Mycoplasma salivarium ), while high SARS-CoV-2 viral burden, poor anti-SARS-CoV-2 antibody response, together with a unique host transcriptome profile of the lower airways were most predictive of mortality. Collectively, these data support the hypothesis that 1) the extent of viral infectivity drives mortality in severe COVID-19, and therefore 2) clinical management strategies targeting viral replication and host responses to SARS-CoV-2 should be prioritized. |
Effectiveness of Influenza Vaccines in the HIVE household cohort over 8 years: is there evidence of indirect protection? (preprint)
Malosh RE , Petrie JG , Callear A , Truscon R , Johnson E , Evans R , Bazzi L , Cheng C , Thompson MS , Martin ET , Monto AS . medRxiv 2021 2021.02.16.21251827 Background The evidence that influenza vaccination programs regularly provide protection to unvaccinated individuals (i.e. indirect effects) of a community is lacking. We sought to determine the direct, indirect, and total effects of influenza vaccine in the Household Influenza Vaccine Evaluation (HIVE) cohort.Methods Using longitudinal data from the HIVE cohort from 2010-11 through 2017-18, we estimated direct, indirect, and total influenza vaccine effectiveness (VE) and the incidence rate ratio of influenza virus infection using adjusted mixed-effect Poisson regression models. Total effectiveness was determined through comparison of vaccinated members of full or partially vaccinated households to unvaccinated individuals in completely unvaccinated households.Results The pooled, direct VE against any influenza was 30.2% (14.0-43.4). Direct VE was higher for influenza A/H1N1 43.9% (3.9 to 63.5) and B 46.7% (17.2 to 57.5) than A/H3N2 31.7% (10.5 to 47.8); and was higher for young children 42.4% (10.1 to 63.0) than adults 18.6% (−6.3 to 37.7). Influenza incidence was highest in completely unvaccinated households (10.6 per 100 person-seasons) and lower at all other levels of household vaccine coverage. We found little evidence of indirect VE after adjusting for potential confounders. Total VET was 56.4% (30.1-72.9) in low coverage, 43.2% (19.5-59.9) in moderate coverage, and 33.0% (12.1 to 49.0) in fully vaccinated households.Conclusion Influenza vaccines may have a benefit above and beyond the direct effect but that effect in this study was small. While there may be exceptions, the goal of global vaccine recommendations should remain focused on provision of documented, direct protection to those vaccinated.Competing Interest StatementThe authors have declared no competing interest.Funding StatementThis work was funded by the National Institute of Allergy and Infectious Disease (R03AI137658).

We investigated self-reported mask use among subjects aged 18 years and older participating in the COVID-19 Community Research Partnership (CRP), a prospective longitudinal COVID-19 surveillance study in the mid-Atlantic and southeastern United States. We included those participants who completed >=5 daily surveys each month from December 1, 2020 through August 31, 2021. Mask use was defined as self-reported use of a face mask or face covering on every interaction with others outside the household within a distance of less than 6 feet. Participants were considered vaccinated if they reported receiving >=1 COVID-19 vaccine dose. Participants (n=17,522) were 91% non-Hispanic White, 68% female, median age 57 years, 26% healthcare workers, with 95% self-reported receiving >=1 COVID-19 vaccine dose through August; mean daily survey response was 85%. Mask use was higher among vaccinated than unvaccinated participants across the study period, regardless of the month of the first dose. Mask use remained relatively stable from December 2020 through April (range 71-80% unvaccinated; 86-93% vaccinated) and declined in both groups beginning in mid-May 2021 to 34% and 42% respectively in June 2021; mask use has increased again since July 2021. Mask use by all was lower during weekends and on Christmas and Easter, regardless of vaccination status. Independent predictors of higher mask use were vaccination, age >=65 years, female sex, racial or ethnic minority group, and healthcare worker occupation, whereas a history of self-reported prior COVID-19 illness was associated with lower use.

Factors Associated with Receipt and Parental Intent for COVID-19 Vaccination of Children Ages 5-11 years (preprint)
Santibanez TA , Lendon JP , Singleton JA , Black CL , Zhou T , Kriss JL , Jain A , Elam-Evans LD , Masters NB , Peacock G . medRxiv 2022 27 Background and Objectives COVID-19 vaccine was first recommended for children ages 5-11 years on November 2, 2021. This report describes COVID-19 vaccination coverage and parental intent to vaccinate their child ages 5-11 years, overall, by sociodemographic characteristics, and by social and behavioral drivers of vaccination, the fourth month after recommendation. Methods We analyzed data from 5,438 interviews conducted in February 2022 from the National Immunization Survey-Child COVID Module (NIS-CCM), a national random-digit-dial cellular telephone survey of households with children. Results 30.9% of children ages 5-11 were vaccinated with >=1 dose of COVID-19 vaccine, 35.2% were unvaccinated and the parent reported they probably or definitely would get the child vaccinated or were unsure, and 33.9% were unvaccinated and the parent probably or definitely would not get the child vaccinated. Vaccination coverage and parental intent differed by sociodemographic variables, including income, health insurance status, and rurality. Parental intent to vaccinate children also differed by ethnicity and race. Concern about the child getting COVID-19 and confidence in vaccine importance and safety were positively associated with vaccination receipt and intent to get the child vaccinated. Conclusions By the fourth month of the COVID-19 vaccination program for children ages 5-11 years, less than one-third were vaccinated, and coverage was lower for some sociodemographic subgroups. An additional one-third of children had a parent who was open to vaccinating the child. Efforts to address parental concerns regarding vaccine safety and to convey the importance of the vaccine might improve vaccination coverage.

Are individual-level risk factors for gastroschisis modified by neighborhood-level socioeconomic factors
Neo DT , Martin CL , Carmichael SL , Gucsavas-Calikoglu M , Conway KM , Evans SP , Feldkamp ML , Gilboa SM , Insaf TZ , Musfee FI , Shaw GM , Shumate C , Werler MM , Olshan AF , Desrosiers TA . Birth Defects Res 2023 115 (15) 1438-1449 BACKGROUND: Two strong risk factors for gastroschisis are young maternal age (<20 years) and low/normal pre-pregnancy body mass index (BMI), yet the reasons remain unknown. We explored whether neighborhood-level socioeconomic position (nSEP) during pregnancy modified these associations. METHODS: We analyzed data from 1269 gastroschisis cases and 10,217 controls in the National Birth Defects Prevention Study (1997-2011). To characterize nSEP, we applied the neighborhood deprivation index and used generalized estimating equations to calculate odds ratios and relative excess risk due to interaction. RESULTS: Elevated odds of gastroschisis were consistently associated with young maternal age and low/normal BMI, regardless of nSEP. High-deprivation neighborhoods modified the association with young maternal age. Infants of young mothers in high-deprivation areas had lower odds of gastroschisis (adjusted odds ratio [aOR]: 3.1, 95% confidence interval [CI]: 2.6, 3.8) than young mothers in low-deprivation areas (aOR: 6.6; 95% CI: 4.6, 9.4). Mothers of low/normal BMI had approximately twice the odds of having an infant with gastroschisis compared to mothers with overweight/obese BMI, regardless of nSEP (aOR range: 1.5-2.3). CONCLUSION: Our findings suggest nSEP modified the association between gastroschisis and maternal age, but not BMI. Further research could clarify whether the modification is due to unidentified biologic and/or non-biologic factors. |
Poliovirus outbreak in New York State, August 2022: qualitative assessment of immediate public health responses and priorities for improving vaccine coverage
Kasstan B , Mounier-Jack S , Chantler T , Masters N , Flores SA , Stokley S , Meek H , Easton D , De Luna-Evans T , Souto M , Punjabi C , Ruppert PS , Rosenberg E , Routh J . Epidemiol Infect 2023 151 e120 In 2022, a case of paralysis was reported in an unvaccinated adult in Rockland County (RC), New York. Genetically linked detections of vaccine-derived poliovirus type 2 (VDPV2) were reported in multiple New York counties, England, Israel, and Canada. The aims of this qualitative study were to: i) review immediate public health responses in New York to assess the challenges in addressing gaps in vaccination coverage; ii) inform a longer-term strategy to improving vaccination coverage in under-vaccinated communities, and iii) collect data to support comparative evaluations of transnational poliovirus outbreaks. Twenty-three semi-structured interviews were conducted with public health professionals, healthcare professionals, and community partners. Results indicate that i) addressing suboptimal vaccination coverage in RC remains a significant challenge after recent disease outbreaks; ii) the poliovirus outbreak was not unexpected and effort should be invested to engage mothers, the key decision-makers on childhood vaccination; iii) healthcare providers (especially paediatricians) received technical support during the outbreak, and may require resources and guidance to effectively contribute to longer-term vaccine engagement strategies; vi) data systems strengthening is required to help track under-vaccinated children. Public health departments should prioritize long-term investments in appropriate communication strategies, countering misinformation, and promoting the importance of the routine immunization schedule. |
Disrupted routine medical visits in children and adolescents during the COVID-19 pandemic, January-June 2021
Badeh SM , Elam-Evans LD , Hill HA , Fredua B . AJPM Focus 2023 100119 INTRODUCTION: Recent studies have indicated the coronavirus disease 2019 (COVID-19) pandemic has disrupted routine vaccinations. This study describes the prevalence and characteristics of children and adolescents experiencing disrupted routine vaccination and other medical visits in the United States between January and June 2021. METHODS: The National Immunization Surveys were the source of data for this cross-sectional analysis (n= 86,893). Parents/guardians of children aged 6 months through 17 years were identified through random digit dialing of cellular phone numbers and interviewed. Disrupted visits were assessed by asking, "In the last two months, was a medical check-up, well child visit, or vaccination appointment for the child delayed, missed, or not scheduled for any reason?" Respondents answering yes were asked "Was it because of COVID-19?" Sociodemographic characteristics of children/adolescents with (1) COVID-19-related missed visits and (2) non-COVID-19-related missed visits were examined. Statistical differences within demographic subgroups were determined using t-tests, with p<0.05 considered statistically significant. Linear regression models were used to examine trends in disrupted visits over time. RESULTS: An estimated 7.9% of children/adolescents had a missed visit attributed to COVID-19; 5.2% had a missed visit that was not COVID-19-related. Among children/adolescents with a COVID-19-related missed visit, a higher percentage were of minority race or ethnicity, lived below the poverty level, had a mother without a college degree, and lived in the western United States. There was a significant decline in COVID-19-related missed visits over time. CONCLUSION: COVID-19 disrupted routine vaccination or other medical visits inequitably. Catch-up immunizations are essential for achieving adequate vaccination of all children/adolescents. |
ICTV virus taxonomy profile: Poxviridae 2023
McInnes CJ , Damon IK , Smith GL , McFadden G , Isaacs SN , Roper RL , Evans DH , Damaso CR , Carulei O , Wise LM , Lefkowitz EJ . J Gen Virol 2023 104 (5) Poxviridae is a family of enveloped, brick-shaped or ovoid viruses. The genome is a linear molecule of dsDNA (128-375 kbp) with covalently closed ends. The family includes the sub-families Entomopoxvirinae, whose members have been found in four orders of insects, and Chordopoxvirinae, whose members are found in mammals, birds, reptiles and fish. Poxviruses are important pathogens in various animals, including humans, and typically result in the formation of lesions, skin nodules, or disseminated rash. Infections can be fatal. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Poxviridae, which is available at ictv.global/report/poxviridae. |
