Recombinational exchange of M-fibril and T-pilus genes generates extensive cell surface diversity in the global group A Streptococcus population
Bessen DE , Beall BW , Hayes A , Huang W , DiChiara JM , Velusamy S , Tettelin H , Jolley KA , Fallon JT , Chochua S , Alobaidallah MSA , Higgs C , Barnett TC , Steemson JT , Proft T , Davies MR . mBio 2024 e0069324 Among genes present in all group A streptococci (GAS), those encoding M-fibril and T-pilus proteins display the highest levels of sequence diversity, giving rise to the two primary serological typing schemes historically used to define strain. A new genotyping scheme for the pilin adhesin and backbone genes is developed and, when combined with emm typing, provides an account of the global GAS strain population. Cluster analysis based on nucleotide sequence similarity assigns most T-serotypes to discrete pilin backbone sequence clusters, yet the established T-types correspond to only half the clusters. The major pilin adhesin and backbone sequence clusters yield 98 unique combinations, defined as "pilin types." Numerous horizontal transfer events that involve pilin or emm genes generate extensive antigenic and functional diversity on the bacterial cell surface and lead to the emergence of new strains. Inferred pilin genotypes applied to a meta-analysis of global population-based collections of pharyngitis and impetigo isolates reveal highly significant associations between pilin genotypes and GAS infection at distinct ecological niches, consistent with a role for pilin gene products in adaptive evolution. Integration of emm and pilin typing into open-access online tools (pubmlst.org) ensures broad utility for end-users wanting to determine the architecture of M-fibril and T-pilus genes from genome assemblies.IMPORTANCEPrecision in defining the variant forms of infectious agents is critical to understanding their population biology and the epidemiology of associated diseases. Group A Streptococcus (GAS) is a global pathogen that causes a wide range of diseases and displays a highly diverse cell surface due to the antigenic heterogeneity of M-fibril and T-pilus proteins which also act as virulence factors of varied functions. emm genotyping is well-established and highly utilized, but there is no counterpart for pilin genes. A global GAS collection provides the basis for a comprehensive pilin typing scheme, and online tools for determining emm and pilin genotypes are developed. Application of these tools reveals the expansion of structural-functional diversity among GAS via horizontal gene transfer, as evidenced by unique combinations of surface protein genes. Pilin and emm genotype correlations with superficial throat vs skin infection provide new insights on the molecular determinants underlying key ecological and epidemiological trends. |
Changes in self-measured blood pressure monitoring use in 14 states from 2019 to 2021 - Impact of the COVID-19 pandemic
Fang J , Zhou W , Hayes DK , Wall HK , Wozniak G , Chung A , Loustalot F . Am J Hypertens 2024 BACKGROUND: Self-measured blood pressure monitoring (SMBP) is an important out-of-office resource that is effective in improving hypertension control. Changes in SMBP use during the COVID-19 pandemic have not been described previously. METHODS: Behavioral Risk Factor Surveillance System (BRFSS) data were used to quantify changes in SMBP use between 2019 (prior COVID-19 pandemic) and 2021 (during COVID-19 pandemic). Fourteen states administered the SMBP module in both years. All data were self-reported from adults who participated the BRFSS survey. We assessed receipt of SMBP recommendation from healthcare professional and actual use of SMBP among those with hypertension (n=68,820). Among those who used SMBP, we assessed SMBP use at home and sharing BP readings electronically with healthcare professional. RESULTS: Among adults with hypertension, there was no significant changes between 2019 and 2021 in those reporting SMBP use (57.0% vs. 55.7%) or receiving recommendation from healthcare professional to use SMBP (66.4% vs. 66.8%). However, among those who used SMBP, there were significant increases in use at home (87.7% vs 93.5%) and sharing BP readings electronically (8.6% vs 13.1%) from 2019 to 2021. Differences were noted by demographic characteristics and residence state. CONCLUSION: Receiving a recommendation from healthcare provider to use SMBP and actual use did not differ before and during the COVID-19 pandemic. However, among those who used SMBP, home use and sharing BP readings electronically with healthcare professional increased significantly, although overall sharing remained low (13.1%). Maximizing advances in virtual connections between clinical and community settings should be leveraged for improved hypertension management. |

Xie O , Morris JM , Hayes AJ , Towers RJ , Jespersen MG , Lees JA , Ben Zakour NL , Berking O , Baines SL , Carter GP , Tonkin-Hill G , Schrieber L , McIntyre L , Lacey JA , James TB , Sriprakash KS , Beatson SA , Hasegawa T , Giffard P , Steer AC , Batzloff MR , Beall BW , Pinho MD , Ramirez M , Bessen DE , Dougan G , Bentley SD , Walker MJ , Currie BJ , Tong SYC , McMillan DJ , Davies MR . Nat Commun 2024 15 (1) 2286 Streptococcus dysgalactiae subsp. equisimilis (SDSE) is an emerging cause of human infection with invasive disease incidence and clinical manifestations comparable to the closely related species, Streptococcus pyogenes. Through systematic genomic analyses of 501 disseminated SDSE strains, we demonstrate extensive overlap between the genomes of SDSE and S. pyogenes. More than 75% of core genes are shared between the two species with one third demonstrating evidence of cross-species recombination. Twenty-five percent of mobile genetic element (MGE) clusters and 16 of 55 SDSE MGE insertion regions were shared across species. Assessing potential cross-protection from leading S. pyogenes vaccine candidates on SDSE, 12/34 preclinical vaccine antigen genes were shown to be present in >99% of isolates of both species. Relevant to possible vaccine evasion, six vaccine candidate genes demonstrated evidence of inter-species recombination. These findings demonstrate previously unappreciated levels of genomic overlap between these closely related pathogens with implications for streptococcal pathobiology, disease surveillance and prevention. |
Prevalence of self-reported hypertension and antihypertensive medication use among adults - United States, 2017-2021
Sekkarie A , Fang J , Hayes D , Loustalot F . MMWR Morb Mortal Wkly Rep 2024 73 (9) 191-198 Hypertension, or high blood pressure, is a major risk factor for heart disease and stroke. It increases with age and is highest among non-Hispanic Black or African American persons, men, persons aged ≥65 years, those of lower socioeconomic status, and those who live in the southern United States. Hypertension affects approximately one half of U.S. adults, and approximately one quarter of those persons have their blood pressure under control. Reducing population-level hypertension prevalence and improving control is a national priority. In 2017, updated guidelines for high blood pressure in adults recommended lowering the blood pressure threshold for diagnosis of hypertension. Analysis of data from the Behavioral Risk Factor Surveillance System found that age-standardized, self-reported diagnosed hypertension was approximately 30% during 2017-2021, with persistent differences by age, sex, race and ethnicity, level of education, and state of residence. During this period, the age-standardized prevalence of antihypertensive medication use among persons with hypertension increased by 3.1 percentage points, from 59.8% to 62.9% (p<0.001). Increases in antihypertensive medication use were observed in most sociodemographic groups and in many states. Assessing current trends in hypertension diagnosis and treatment can help guide the development of policies and implementation of interventions to reduce this important risk factor for cardiovascular disease and can aid in addressing health disparities. |
Critical elements of community engagement to address disparities and related social determinants of health: The CDC Community Approaches to Reducing STDs (CARS) initiative
Rhodes SD , Daniel-Ulloa J , Wright SS , Mann-Jackson L , Johnson DB , Hayes NA , Valentine JA . Sex Transm Dis 2021 48 (1) 49-55 BACKGROUND: Community Approaches to Reducing Sexually Transmitted Disease (CARS), a unique initiative of the US Centers for Disease Control and Prevention, promotes the use of community engagement to increase sexually transmitted disease (STD) prevention, screening, and treatment and to address locally prioritized STD-related social determinants of health within communities experiencing STD disparities, including youth, persons of color, and sexual and gender minorities. We sought to identify elements of community engagement as applied within CARS. METHODS AND MATERIALS: Between 2011 and 2018, we collected and analyzed archival and in-depth interview data to identify and explore community engagement across 8 CARS sites. Five to 13 interview participants (mean, 7) at each site were interviewed annually. Participants included project staff and leadership, community members, and representatives from local community organizations (e.g., health departments; lesbian, gay, bisexual, transgender, and queer-serving organizations; faith organizations; businesses; and HIV-service organizations) and universities. Data were analyzed using constant comparison, an approach to grounded theory development. RESULTS: Twelve critical elements of community engagement emerged, including commitment to engagement, partner flexibility, talented and trusted leadership, participation of diverse sectors, establishment of vision and mission, open communication, reducing power differentials, working through conflict, identifying and leveraging resources, and building a shared history. CONCLUSIONS: This study expands the community engagement literature within STD prevention, screening, and treatment by elucidating some of the critical elements of the approach and provides guidance for practitioners, researchers, and their partners as they develop, implement, and evaluate strategies to reduce STD disparities. |

Barriers and facilitators to HIV service access among Hispanic/Latino gay, bisexual, and other men who have sex with men in metropolitan Atlanta-a qualitative analysis
Hassan R , Saldana CS , Garlow EW , Gutierrez M , Hershow RB , Elimam D , Adame JF , Andía JF , Padilla M , Gonzalez Jimenez N , Freeman D , Johnson EN , Reed K , Holland DP , Orozco H , Pedraza G , Hayes C , Philpott DC , Curran KG , Wortley P , Agnew-Brune C , Gettings JR . J Urban Health 2023 100 (6) 1193-1201 Hispanic/Latino persons are disproportionately impacted by HIV in the US, and HIV diagnoses among Hispanic/Latino men in Georgia have increased over the past decade, particularly in metropolitan Atlanta. In 2022, the Georgia Department of Public Health detected five clusters of rapid HIV transmission centered among Hispanic/Latino gay, bisexual, and other men who have sex with men (HLMSM) in metropolitan Atlanta. We conducted in-depth interviews with 65 service providers and 29 HLMSM to identify barriers and facilitators to HIV service access for HLMSM. Interviews were audio recorded, transcribed, and translated, if needed. Initial data analyses were conducted rapidly in the field to inform public health actions. We then conducted additional analyses including line-by-line coding of the interview transcripts using a thematic analytic approach. We identified four main themes. First, inequity in language access was a predominant barrier. Second, multiple social and structural barriers existed. Third, HLMSM encountered intersectional stigma. Finally, the HLMSM community is characterized by its diversity, and there is not a one-size-fits-all approach to providing appropriate care to this population. The collection of qualitative data during an HIV cluster investigation allowed us to quickly identity barriers experienced by HLMSM when accessing HIV and other medical care, to optimize public health response and action. Well-designed program evaluation and implementation research may help elucidate specific strategies and tools to reduce health disparities, ensure equitable service access for HLMSM, and reduce HIV transmission in this population. |
Hypertension prevalence and control among U.S. Women of reproductive age
Weng X , Woodruff RC , Park S , Thompson-Paul AM , He S , Hayes D , Kuklina E , Therrien NL , Jackson SL . Am J Prev Med 2023 INTRODUCTION: Hypertension is a risk factor for cardiovascular disease, a leading cause of death among women of reproductive age (WRA, women aged 18-44 years). This study estimated hypertension prevalence and control among WRA at the national and state levels using electronic health record (EHR) data. METHODS: Non-pregnant WRA were included in this cross-sectional study using 2019 IQVIA™ Ambulatory Electronic Medical Records - US national data (analyzed in 2023). Suspected hypertension was identified using any of these criteria: ≥1 hypertension diagnosis code, ≥2 blood pressure (BP) readings ≥140/90 mmHg on separate days, or ≥1 antihypertensive medication. Among WRA with hypertension, the latest BP in 2019 was used to identify hypertension control (BP <140/90 mmHg). Estimates were age standardized and stratified by race or Hispanic ethnicity, region, and states with sufficient data. Tukey tests compared estimates by race or Hispanic ethnicity, region, and comorbidities. RESULTS: Among 2,125,084 WRA (62.1% White, 8.8% Black, and 29.1% other [including Hispanic, Asian, other, or unknown]) with a mean age of 31.7 years, hypertension prevalence was 14.5%. Of those with hypertension, 71.9% had controlled BP. Black WRA had a higher hypertension prevalence (22.3% vs. 14.4%, p<0.05) but lower control (60.6% vs. 73.9%, p<0.05) than White WRA. State-level hypertension prevalence ranged from 13.7% (Massachusetts) to 36% (Alabama), and control ranged from 82.9% (Kansas) to 59.2% (the District of Columbia). CONCLUSIONS: This study provides the first state-level estimates of hypertension control among WRA. EHR data complements traditional hypertension surveillance data and provides further information for efforts to prevent and manage hypertension among WRA. |
Risk factors for heat-related illness resulting in death or hospitalization in the oil and gas extraction industry
Lin NW , Ramirez-Cardenas A , Wingate KC , King BS , Scott K , Hagan-Hayes K . J Occup Environ Hyg 2023 1-14 Many oil and gas extraction (OGE) activities occur in high heat environments, resulting in significant risk of heat-related illness among outdoor workers in this industry. This report highlights cases of occupational heat-related illness that resulted in death and identifies common risk factors for heat-related fatalities and hospitalizations among OGE workers. Two databases maintained by the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) were reviewed to identify heat-related fatalities, hospitalizations, and associated risk factors among OGE workers. Nine fatalities and associated risk factors were identified during 2014-2019 from NIOSH's Fatalities in Oil and Gas Extraction (FOG) Database. Risk factors identified included those commonly associated with heat-related fatalities: new workers not acclimatized to heat, inadequate heat stress training, and underlying hypertension or cardiovascular disease. Of particular note, substance use was identified as a significant risk factor as more than half of the fatalities included a positive post-mortem test for amphetamines or methamphetamines. Fifty heat-related hospitalizations were identified from OSHA's Severe Injury Report Database during January 2015-May 2021. Heat stress has been and will continue to be an important cause of fatality and adverse health effects in OGE as hot outdoor working conditions become more common and extreme. More emphasis on heat stress training, acclimatization regimens, medical screening, and implementation of workplace supportive recovery programs may reduce heat-related fatalities and injuries in this industry. |
Population-level viremia predicts HIV incidence at the community level across the Universal Testing and Treatment Trials in eastern and southern Africa
Larmarange J , Bachanas P , Skalland T , Balzer LB , Iwuji C , Floyd S , Mills LA , Pillay D , Havlir D , Kamya MR , Ayles H , Wirth K , Dabis F , Hayes R , Petersen M . PLOS Glob Public Health 2023 3 (7) e0002157 Universal HIV testing and treatment (UTT) strategies aim to optimize population-level benefits of antiretroviral treatment. Between 2012 and 2018, four large community randomized trials were conducted in eastern and southern Africa. While their results were broadly consistent showing decreased population-level viremia reduces HIV incidence, it remains unclear how much HIV incidence can be reduced by increasing suppression among people living with HIV (PLHIV). We conducted a pooled analysis across the four UTT trials. Leveraging data from 105 communities in five countries, we evaluated the linear relationship between i) population-level viremia (prevalence of non-suppression-defined as plasma HIV RNA >500 or >400 copies/mL-among all adults, irrespective of HIV status) and HIV incidence; and ii) prevalence of non-suppression among PLHIV and HIV incidence, using parametric g-computation. HIV prevalence, measured in 257 929 persons, varied from 2 to 41% across the communities; prevalence of non-suppression among PLHIV, measured in 31 377 persons, from 3 to 70%; population-level viremia, derived from HIV prevalence and non-suppression, from < 1% to 25%; and HIV incidence, measured over 345 844 person-years (PY), from 0.03/100PY to 3.46/100PY. Decreases in population-level viremia were strongly associated with decreased HIV incidence in all trials (between 0.45/100PY and 1.88/100PY decline in HIV incidence per 10 percentage points decline in viremia). Decreases in non-suppression among PLHIV were also associated with decreased HIV incidence in all trials (between 0.06/100PY and 0.17/100PY decline in HIV incidence per 10 percentage points decline in non-suppression). Our results support both the utility of population-level viremia as a predictor of incidence, and thus a tool for targeting prevention interventions, and the ability of UTT approaches to reduce HIV incidence by increasing viral suppression. Implementation of universal HIV testing approaches, coupled with interventions to leverage linkage to treatment, adapted to local contexts, can reduce HIV acquisition at population level. |

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.

Modifications to student quarantine policies in K-12 schools implementing multiple COVID-19 prevention strategies restores in-person education without increasing SARS-CoV-2 transmission risk, January-March 2021 (preprint)
Dawson P , Worrell MC , Malone S , Fritz SA , McLaughlin HP , Montgomery BK , Boyle M , Gomel A , Hayes S , Maricque B , Lai AM , Neidich JA , Tinker SC , Lee JS , Tong S , Orscheln RC , Charney R , Rebmann T , Mooney J , Rains C , Yoon N , Petit M , Towns K , Goddard C , Schmidt S , Barrios LC , Neatherlin JC , Salzer JS , Newland JG . medRxiv 2022 21 Objective: To determine whether modified K-12 student quarantine policies that allow some students to continue in-person education during their quarantine period increase schoolwide SARS-CoV-2 transmission risk following the increase in cases in winter 2020-2021. Method(s): We conducted a prospective cohort study of COVID-19 cases and exposures among students and staff (n=65,621) in 103 Missouri public schools. Participants were offered free, saliva-based RT-PCR testing. An adjusted Cox regression model compared hazard rates of school-based SARS-CoV-2 infections between schools with a modified versus standard quarantine policy. Result(s): From January-March 2021, a projected 23 (1%) school-based transmission events occurred among 1,636 school close contacts. There was no difference in the adjusted hazard rates of school-based SARS-CoV-2 infections between schools with a modified versus standard quarantine policy (hazard ratio=1.00; 95% confidence interval: 0.97-1.03). Discussion(s): School-based SARS-CoV-2 transmission was rare in 103 K-12 schools implementing multiple COVID-19 prevention strategies. Modified student quarantine policies were not associated with increased school incidence of COVID-19. Modifications to student quarantine policies may be a useful strategy for K-12 schools to safely reduce disruptions to in-person education during times of increased COVID-19 community incidence.

Timing of outpatient postpartum care utilization among women with chronic hypertension and hypertensive disorders of pregnancy
Aqua JK , Ford ND , Pollack LM , Lee JS , Kuklina EV , Hayes DK , Vaughan AS , Coronado F . Am J Obstet Gynecol MFM 2023 5 (9) 101051 BACKGROUND: The postpartum period represents an opportunity to assess the cardiovascular health of women who experience chronic hypertension or hypertensive disorders of pregnancy. OBJECTIVES: To determine whether women with chronic hypertension or hypertensive disorders of pregnancy access outpatient postpartum care more quickly compared to women with no hypertension. STUDY DESIGN: We used data from the Merative MarketScan® Commercial Claims and Encounters Database. We included 275,937 commercially insured women aged 12-55 years who had a live birth or stillbirth delivery hospitalization between 2017-2018 and continuous insurance enrollment from 3 months before the estimated start of pregnancy to 6 months after delivery discharge. Using International Classification of Diseases 10th Revision Clinical Modification codes, we identified hypertensive disorders of pregnancy from inpatient or outpatient claims from 20 weeks gestation through delivery hospitalization and identified chronic hypertension from inpatient or outpatient claims from the beginning of the continuous enrollment period through delivery hospitalization. Distributions of time-to-event survival curves (time-to-first outpatient postpartum visit with a women's health, primary care, or cardiology provider) were compared between the hypertension types using Kaplan-Meier estimators and log rank tests. We used Cox proportional hazards models to estimate adjusted hazard ratios (aHR) and 95% confidence intervals (CI). Time points of interest (3, 6, and 12 weeks) were evaluated per clinical postpartum care guidelines. RESULTS: Among commercially insured women, the prevalences of hypertensive disorders of pregnancy, chronic hypertension, and no documented hypertension were 11.7%, 3.4%, and 84.8%, respectively. The proportions of women with a visit within 3 weeks of delivery discharge were 28.5%, 26.4%, and 16.0% for hypertensive disorders of pregnancy, chronic, and no documented hypertension, respectively. By 12 weeks, the proportions increased to 62.4%, 64.5%, and 54.2%, respectively. Kaplan-Meier analyses indicated significant differences in utilization by hypertension type and interaction between hypertension type and time before and after 6 weeks. In adjusted Cox proportional hazards models, the utilization rate before 6 weeks among women with hypertensive disorders of pregnancy was 1.42 times the rate for women with no documented hypertension [aHR=1.42, 95% CI (1.39-1.45)]. Women with chronic hypertension also had higher utilization rates compared to women with no documented hypertension before 6 weeks [aHR=1.28, 95% CI: (1.24-1.33)]. Only chronic hypertension was significantly associated with utilization compared to the no documented hypertension group after 6 weeks [aHR=1.09, 95% CI: (1.03-1.14)]. CONCLUSIONS: In the 6 weeks following delivery discharge, women with hypertensive disorders of pregnancy and chronic hypertension attended outpatient postpartum care visits sooner than women with no documented hypertension. However, after 6 weeks this difference extended only to women with chronic hypertension. Overall, postpartum care utilization remained around 50-60% by 12 weeks in all groups. Addressing barriers to postpartum care attendance can ensure timely care for women at high risk for cardiovascular disease. |
Public Health Response to Clusters of Rapid HIV Transmission Among Hispanic or Latino Gay, Bisexual, and Other Men Who Have Sex with Men - Metropolitan Atlanta, Georgia, 2021-2022.
Saldana C , Philpott DC , Mauck DE , Hershow RB , Garlow E , Gettings J , Freeman D , France AM , Johnson EN , Ajmal A , Elimam D , Reed K , Sulka A , Adame JF , Andía JF , Gutierrez M , Padilla M , Jimenez NG , Hayes C , McClung RP , Cantos VD , Holland DP , Scott JY , Oster AM , Curran KG , Hassan R , Wortley P . MMWR Morb Mortal Wkly Rep 2023 72 (10) 261-264 During February 2021-June 2022, the Georgia Department of Public Health (GDPH) detected five clusters of rapid HIV transmission concentrated among Hispanic or Latino (Hispanic) gay, bisexual, and other men who have sex with men (MSM) in metropolitan Atlanta. The clusters were detected through routine analysis of HIV-1 nucleotide sequence data obtained through public health surveillance (1,2). Beginning in spring 2021, GDPH partnered with health districts with jurisdiction in four metropolitan Atlanta counties (Cobb, DeKalb, Fulton, and Gwinnett) and CDC to investigate factors contributing to HIV spread, epidemiologic characteristics, and transmission patterns. Activities included review of surveillance and partner services interview data,(†) medical chart reviews, and qualitative interviews with service providers and Hispanic MSM community members. By June 2022, these clusters included 75 persons, including 56% who identified as Hispanic, 96% who reported male sex at birth, 81% who reported male-to-male sexual contact, and 84% of whom resided in the four metropolitan Atlanta counties. Qualitative interviews identified barriers to accessing HIV prevention and care services, including language barriers, immigration- and deportation-related concerns, and cultural norms regarding sexuality-related stigma. GDPH and the health districts expanded coordination, initiated culturally concordant HIV prevention marketing and educational activities, developed partnerships with organizations serving Hispanic communities to enhance outreach and services, and obtained funding for a bilingual patient navigation program with academic partners to provide staff members to help persons overcome barriers and understand the health care system. HIV molecular cluster detection can identify rapid HIV transmission among sexual networks involving ethnic and sexual minority groups, draw attention to the needs of affected populations, and advance health equity through tailored responses that address those needs. |
HIV prevention services for Hispanic/Latino persons in THRIVE, 2015-2020
Bonacci RA , Tanner MR , Zhu W , Hayes T , Dominguez KL , Iqbal K , Wiener J , Drezner K , Jennings JM , Tsoi B , Wendell D , Hoover KW . Am J Prev Med 2023 65 (2) 213-220 INTRODUCTION: Hispanic/Latino men who have sex with men (MSM) and transgender women (TGW) are disproportionately affected by HIV in the U.S. This study evaluated HIV prevention services and outcomes among Hispanic/Latino MSM and TGW in the targeted highly effective interventions to reduce the HIV epidemic (THRIVE) demonstration project and consider lessons learned. METHODS: The authors described the THRIVE demonstration project services provided to Hispanic/Latino MSM and TGW in 7 U.S. jurisdictions from 2015 to 2020. HIV prevention service outcomes were compared between 1 site with (2,147 total participants) and 6 sites without (1,129 total participants) Hispanic/Latino-oriented pre-exposure prophylaxis clinical services, and Poisson regression was used to estimate the adjusted RR between sites and pre-exposure prophylaxis outcomes. Analyses were conducted from 2021 to 2022. RESULTS: The THRIVE demonstration project served 2,898 and 378 Hispanic/Latino MSM and TGW, respectively, with 2,519 MSM (87%) and 320 TGW (85%) receiving ≥1 HIV screening test. Among 2,002 MSM and 178 TGW eligible for pre-exposure prophylaxis, 1,011 (50%) MSM and 98 (55%) TGW received pre-exposure prophylaxis prescriptions, respectively. MSM and TGW were each 2.0 times more likely to be linked to pre-exposure prophylaxis (95% CI=1.4, 2.9 and 95% CI=1.2, 3.6, respectively) and 1.6 and 2.1 times more likely to be prescribed pre-exposure prophylaxis (95% CI=1.1, 2.2 and 95% CI=1.1, 4.1), respectively, at the site providing Hispanic/Latino-oriented pre-exposure prophylaxis clinical services than at other sites and adjusted for age group. CONCLUSIONS: The THRIVE demonstration project delivered comprehensive HIV prevention services to Hispanic/Latino MSM and TGW. Hispanic/Latino-oriented clinical settings may improve HIV prevention service delivery to persons in Hispanic/Latino communities. |
Less than ideal cardiovascular health among adults is associated with experiencing adverse childhood events: BRFSS 2019
Hayes DK , Wiltz JL , Fang J , Loustalot F . Prev Med 2023 169 107457 Ideal cardiovascular health (CVH) is associated with a lower risk of heart disease and stroke while adverse childhood events (ACEs) are related to health behaviors (e.g., smoking, unhealthy diet) and conditions (e.g., hypertension, diabetes) associated with CVH. Data from the 2019 Behavioral Risk Factor Surveillance System was used to explore ACEs and CVH among 86,584 adults ≥18 years from 20 states. CVH was defined as poor (0-2), intermediate (3-5), and ideal (6-7) from summation of survey indicators (normal weight, healthy diet, adequate physical activity, not smoking, no hypertension, no high cholesterol, and no diabetes). ACEs was summed by number (0,1, 2, 3, and ≥4). A generalized logit model estimated associations between poor and intermediate CVH (ideal as referent) and ACEs accounting for age, race/ethnicity, sex, education, and health care coverage. Overall, 16.7% (95% Confidence Interval[CI]:16.3-17.1) had poor, 72.4% (95%CI:71.9-72.9) had intermediate, and 10.9% (95%CI:10.5-11.3) had ideal CVH. Zero ACEs were reported for 37.0% (95%CI:36.4-37.6), 22.5% (95%CI:22.0-23.0) reported 1, 12.7% (95%CI:12.3-13.1) reported 2, 8.5% (95%CI:8.2-8.9) reported 3, and 19.3% (95%CI:18.8-19.8) reported ≥4 ACEs. Those with 1 (Adjusted Odds Ratio [AOR] = 1.27;95%CI = 1.11-1.46), 2 (AOR = 1.63;95%CI:1.36-1.96), 3 (AOR = 2.01;95%CI:1.66-2.44), and ≥ 4 (AOR = 2.47;95%CI:2.11-2.89) ACEs were more likely to report poor (vs. ideal) CVH compared to those with 0 ACEs. Those who reported 2 (AOR = 1.28;95%CI = 1.08-1.51), 3 (AOR = 1.48;95%CI:1.25-1.75), and ≥ 4 (AOR = 1.59;95%CI:1.38-1.83) ACEs were more likely to report intermediate (vs. ideal) CVH compared to those with 0 ACEs. Preventing and mitigating the harms of ACEs and addressing barriers to ideal CVH, particularly social and structural determinants, may improve health. |
Achieving the UNAIDS 90-90-90 targets: a comparative analysis of four large community randomised trials delivering universal testing and treatment to reduce HIV transmission in sub-Saharan Africa
Sabapathy K , Balzer L , Larmarange J , Block L , Floyd S , Iwuji C , Wirth K , Ayles H , Fidler S , Kamya M , Petersen M , Havlir D , Dabis F , Moore J , Hayes R . BMC Public Health 2022 22 (1) 2333 BACKGROUND: Four large community-randomized trials examining universal testing and treatment (UTT) to reduce HIV transmission were conducted between 2012-2018 in Botswana, Kenya, Uganda, Zambia and South Africa. In 2014, the UNAIDS 90-90-90 targets were adopted as a useful metric to monitor coverage. We systematically review the approaches used by the trials to measure intervention delivery, and estimate coverage against the 90-90-90 targets. We aim to provide in-depth understanding of the background contexts and complexities that affect estimation of population-level coverage related to the 90-90-90 targets. METHODS: Estimates were based predominantly on "process" data obtained during delivery of the interventions which included a combination of home-based and community-based services. Cascade coverage data included routine electronic health records, self-reported data, survey data, and active ascertainment of HIV viral load measurements in the field. RESULTS: The estimated total adult populations of trial intervention communities included in this study ranged from 4,290 (TasP) to 142,250 (Zambian PopART Arm-B). The estimated total numbers of PLHIV ranged from 1,283 (TasP) to 20,541 (Zambian PopART Arm-B). By the end of intervention delivery, the first-90 target (knowledge of HIV status among all PLHIV) was met by all the trials (89.2%-94.0%). Three of the four trials also achieved the second- and third-90 targets, and viral suppression in BCPP and SEARCH exceeded the UNAIDS target of 73%, while viral suppression in the Zambian PopART Arm-A and B communities was within a small margin (~3%) of the target. CONCLUSIONS: All four UTT trials aimed to implement wide-scale testing and treatment for HIV prevention at population level and showed substantial increases in testing and treatment for HIV in the intervention communities. This study has not uncovered any one estimation approach which is superior, rather that several approaches are available and researchers or policy makers seeking to measure coverage should reflect on background contexts and complexities that affect estimation of population-level coverage in their specific settings. All four trials surpassed UNAIDS targets for universal testing in their intervention communities ahead of the 2020 milestone. All but one of the trials also achieved the 90-90 targets for treatment and viral suppression. UTT is a realistic option to achieve 95-95-95 by 2030 and fast-track the end of the HIV epidemic. |
HIV pre-exposure prophylaxis services for black and hispanic or latino gay, bisexual, and other men who have sex with men and transgender women in THRIVE, 2015-2020

J Acquir Immune Defic Syndr 2022 92 (4) 286-292 BACKGROUND: AND SETTING: From 2015-2020 the THRIVE project supported seven U.S. health departments to improve HIV prevention services for Black or African American (Black) and Hispanic or Latino gay, bisexual, and other men who have sex with men (GBM) and transgender women (TGW). METHODS: We described services provided in the THRIVE PrEP continuum. Using Poisson regression models we estimated associations between race or ethnicity and age and PrEP screening, linkage, and prescription. We examined associations between co-location of services and PrEP linkage and prescription for two sites. RESULTS: THRIVE served 12,972 GBM without HIV; 37% of PrEP-eligible GBM were prescribed PrEP. THRIVE served 1,185 TGW without HIV; 45% of PrEP-eligible TGW were prescribed PrEP. Black and Hispanic or Latino GBM were 29% (RR=0.71, 95% CI 0.66-0.77) and 19% (RR=0.81, 95% CI 0.75-0.87) less likely, respectively, to be prescribed PrEP than White GBM. GBM 18-24 years and ≥55 years were 19% (RR=0.81, 95% CI 0.75-0.87) and 22% (RR=0.78, 95% CI 0.67-0.9) less likely, respectively, to be prescribed PrEP compared to those 35-44 years. Co-located services were associated with a 54% (RR = 1.54, 95% CI 1.44-1.64) and a 31% (RR = 1.31, 95% CI: 1.19-1.43) greater likelihood of PrEP linkage and prescription respectively compared to services at different locations. CONCLUSIONS: THRIVE provided PrEP to higher proportions of PrEP-eligible persons than current national estimates, however PrEP use disparities persist. Co-location of services may be a useful component of jurisdictional strategies to increase PrEP coverage. |
Strategies to increase the intention to get vaccinated against COVID-19: Findings from a nationally representative survey of US adults, October 2020 to October 2021.
Naeim A , Guerin RJ , Baxter-King R , Okun AH , Wenger N , Sepucha K , Stanton AL , Rudkin A , Holliday D , Rossell Hayes A , Vavreck L . Vaccine 2022 40 (52) 7571-7578 OBJECTIVES: We examined COVID-19 vaccination status, intention, and hesitancy and the effects of five strategies to increase the willingness of unvaccinated adults (≥18 years) to get a COVID vaccine. METHODS: Online surveys were conducted between October 1-17, 2020 (N = 14,946), December 4-16, 2020 (N = 15,229), April 8-22, 2021 (N = 14,557), June 17-July 6, 2021 (N = 30,857), and September 3-October 4, 2021 (N = 33,088) with an internet-based, non-probability opt-in sample of U.S. adults matching demographic quotas. Respondents were asked about current COVID-19 vaccination status, intention and hesitancy to get vaccinated, and reasons for vaccine hesitancy. Unvaccinated respondents were assigned to treatment groups to test the effect of five strategies (endorsements, changing social restrictions, financial incentives, vaccine requirements for certain activities, and vaccine requirements for work). Chi-square tests of independence were performed to detect differences in the response distributions. RESULTS: Willingness to be vaccinated (defined as being vaccinated or planning to be) increased over time from 47.6 % in October 2020 to 81.1 % in October 2021. By October 2021, across most demographic groups, over 75 % of survey respondents had been or planned to be vaccinated. In terms of strategies: (1) endorsements had no positive effect, (2) relaxing the need for masks and social distancing increased Intention to Get Vaccinated (IGV) by 6.4 % (p < 0.01), (3) offering financial incentives increased the IGV between 12.3 and 18.9 % (p <.001), (4) vaccine requirements for attending sporting events or traveling increased IGV by 7.8 % and 9.1 %, respectively (p = 0.02), and vaccine requirement for work increased IGV by 35.4 %. The leading causes (not mutually exclusive) for hesitancy were concerns regarding vaccine safety (52.5 %) or side effects (51.6 %), trust in the government's motives (41.0 %), and concerns about vaccine effectiveness (37.6 %). CONCLUSIONS: These findings suggest that multiple strategies may be effective and needed to increase COVID-19 vaccination among hesitant adults during the pandemic. |
Modifications to student quarantine policies in K-12 schools implementing multiple COVID-19 prevention strategies restores in-person education without increasing SARS-CoV-2 transmission risk, January-March 2021.
Dawson P , Worrell MC , Malone S , Fritz SA , McLaughlin HP , Montgomery BK , Boyle M , Gomel A , Hayes S , Maricque B , Lai AM , Neidich JA , Tinker SC , Lee JS , Tong S , Orscheln RC , Charney R , Rebmann T , Mooney J , Rains C , Yoon N , Petit M , Towns K , Goddard C , Schmidt S , Barrios LC , Neatherlin JC , Salzer JS , Newland JG . PLoS One 2022 17 (10) e0266292 OBJECTIVE: To determine whether modified K-12 student quarantine policies that allow some students to continue in-person education during their quarantine period increase schoolwide SARS-CoV-2 transmission risk following the increase in cases in winter 2020-2021. METHODS: We conducted a prospective cohort study of COVID-19 cases and close contacts among students and staff (n = 65,621) in 103 Missouri public schools. Participants were offered free, saliva-based RT-PCR testing. The projected number of school-based transmission events among untested close contacts was extrapolated from the percentage of events detected among tested asymptomatic close contacts and summed with the number of detected events for a projected total. An adjusted Cox regression model compared hazard rates of school-based SARS-CoV-2 infections between schools with a modified versus standard quarantine policy. RESULTS: From January-March 2021, a projected 23 (1%) school-based transmission events occurred among 1,636 school close contacts. There was no difference in the adjusted hazard rates of school-based SARS-CoV-2 infections between schools with a modified versus standard quarantine policy (hazard ratio = 1.00; 95% confidence interval: 0.97-1.03). DISCUSSION: School-based SARS-CoV-2 transmission was rare in 103 K-12 schools implementing multiple COVID-19 prevention strategies. Modified student quarantine policies were not associated with increased school incidence of COVID-19. Modifications to student quarantine policies may be a useful strategy for K-12 schools to safely reduce disruptions to in-person education during times of increased COVID-19 community incidence. |
Cost-effectiveness of pharmacologic treatment options for women with endocrine-refractory or triple-negative metastatic breast cancer
Wheeler SB , Rotter J , Gogate A , Reeder-Hayes KE , Drier SW , Ekwueme DU , Fairley TL , Rocque GB , Trogdon JG . J Clin Oncol 2022 41 (1) Jco2102473 PURPOSE: Treatments for endocrine-refractory or triple-negative metastatic breast cancer (mBC) are modestly effective at prolonging life and improving quality of life but can be extremely expensive. Given these tradeoffs in quality of life and cost, the optimal choice of treatment sequencing is unclear. Cost-effectiveness analysis can explicitly quantify such tradeoffs, enabling more informed decision making. Our objective was to estimate the societal cost-effectiveness of different therapeutic alternatives in the first- to third-line sequences of single-agent chemotherapy regimens among patients with endocrine-refractory or triple-negative mBC. METHODS: Using three dynamic microsimulation models of 10,000 patients each, three cohorts were simulated, based upon prior chemotherapy exposure: (1) unexposed to either taxane or anthracycline, (2) taxane- and anthracycline-exposed, and (3) taxane-exposed/anthracycline-naive. We focused on the following single-agent chemotherapy regimens as reasonable and commonly used options in the first three lines of therapy for each cohort, based upon feedback from oncologists treating endocrine-refractory or triple-negative mBC: (1) for taxane- and anthracycline-unexposed patients, paclitaxel, capecitabine (CAPE), or pegylated liposomal doxorubicin; (2) for taxane- and anthracycline-exposed patients, Eribulin, CAPE, or carboplatin; and (3) for taxane-exposed/anthracycline-naive patients, pegylated liposomal doxorubicin, CAPE, or Eribulin. RESULTS: In each cohort, accumulated quality-adjusted life-years were similar between regimens, but total societal costs varied considerably. Sequences beginning first-line treatment with paclitaxel, carboplatin, and CAPE, respectively, for cohorts 1, 2, and 3, had lower costs and similar or slightly better outcomes compared with alternative options. CONCLUSION: In this setting where multiple single-agent chemotherapy options are recommended by clinical guidelines and share similar survival and adverse event trajectories, treatment sequencing approaches that minimize costs early may improve the value of care. |
Clinician knowledge and practices related to a patient history of hypertensive disorders of pregnancy
Ford ND , Robbins CL , Nandi N , Hayes DK , Loustalot F , Kuklina E , Ko JY . Obstet Gynecol 2022 139 (5) 898-906 OBJECTIVE: To describe clinician screening practices for prior hypertensive disorders of pregnancy, knowledge of future risks associated with hypertensive disorders of pregnancy, barriers and facilitators to referrals for cardiovascular disease risk evaluation in women with prior hypertensive disorders of pregnancy, and variation by clinician- and practice-level characteristics. METHODS: We used data from Fall DocStyles 2020, a cross-sectional, web-based panel survey of currently practicing U.S. clinicians. Of 2,231 primary care physicians, obstetrician-gynecologists (ob-gyns), nurse practitioners, and physician assistants invited to participate, 67.3% (n=1,502) completed the survey. We calculated the prevalence of screening, knowledge of future risks, and barriers and facilitators to referrals, and assessed differences by clinician type using 2 tests. We evaluated associations between clinician- and practice-level characteristics and not screening using a multivariable log-binomial model. RESULTS: Overall, 73.6% of clinicians screened patients for a history of hypertensive disorders of pregnancy; ob-gyns reported the highest rate of screening (94.8%). Overall, 24.8% of clinicians correctly identified all cardiovascular risks associated with hypertensive disorders of pregnancy listed in the survey. Lack of patient follow-through (51.5%) and patient refusal (33.6%) were the most frequently cited barriers to referral. More referral options (42.9%), patient education materials (36.2%), and professional guidelines (34.1%) were the most frequently cited resources needed to facilitate referrals. In the multivariable model, primary care physicians and nurse practitioners, as well as physician assistants, were more likely than ob-gyns to report not screening (adjusted prevalence ratio 5.54, 95% CI 3.24-9.50, and adjusted prevalence ratio 7.42, 95% CI 4.27-12.88, respectively). Clinicians seeing fewer than 80 patients per week (adjusted prevalence ratio 1.81, 95% CI 1.43-2.28) were more likely to not screen relative to those seeing 110 or more patients per week. CONCLUSION: Three quarters of clinicians reported screening for a history of hypertensive disorders of pregnancy; however, only one out of four clinicians correctly identified all of the cardiovascular risks associated with hypertensive disorders of pregnancy listed in the survey. |
Prevalence, treatment, and control of hypertension among US women of reproductive age by race/hispanic origin
Ford ND , Robbins CL , Hayes DK , Ko JY , Loustalot F . Am J Hypertens 2022 35 (8) 723-730 BACKGROUND: To explore the prevalence, pharmacologic treatment, and control of hypertension among US non-pregnant women of reproductive age by race/Hispanic origin to identify potential gaps in care. METHODS: We pooled data from the 2011 to March 2020 (pre-pandemic) National Health and Nutrition Examination Survey cycles. Our analytic sample included 4,590 non-pregnant women aged 20-44 years who had at least one examiner-measured blood pressure (BP) value. We estimated prevalences and 95% CIs of hypertension, pharmacologic treatment, and control based on the 2003 Joint Committee on High Blood Pressure (JNC 7) and the 2017 American College of Cardiology and the American Heart Association (ACC/AHA) guidelines. We evaluated differences by race/Hispanic origin using Rao-Scott chi-square tests. RESULTS: Applying ACC/AHA guidelines, hypertension prevalence ranged from 14.0% (95% CI: 12.0, 15.9) among Hispanic women to 30.9% (95% CI: 27.8, 34.0) among Non-Hispanic Black women. Among women with hypertension, non-Hispanic Black women had the highest eligibility for pharmacological treatment (65.5%, 95% CI: 60.4, 70.5); current use was highest among White women (61.8%, 95% CI: 53.8, 69.9). BP control ranged from 5.2% (95% CI: 1.1, 9.3) among women of Another or Multiple non-Hispanic races to 18.6% (95% CI: 12.1, 25.0) among Hispanic women. CONCLUSIONS: These findings highlight the importance of monitoring hypertension, pharmacologic treatment, and control by race/Hispanic origin and addressing barriers to equitable hypertension care among women of reproductive age. |
Hypertensive disorders in pregnancy and mortality at delivery hospitalization - United States, 2017-2019
Ford ND , Cox S , Ko JY , Ouyang L , Romero L , Colarusso T , Ferre CD , Kroelinger CD , Hayes DK , Barfield WD . MMWR Morb Mortal Wkly Rep 2022 71 (17) 585-591 Hypertensive disorders in pregnancy (HDPs), defined as prepregnancy (chronic) or pregnancy-associated hypertension, are common pregnancy complications in the United States.* HDPs are strongly associated with severe maternal complications, such as heart attack and stroke (1), and are a leading cause of pregnancy-related death in the United States.(†) CDC analyzed nationally representative data from the National Inpatient Sample to calculate the annual prevalence of HDP among delivery hospitalizations and by maternal characteristics, and the percentage of in-hospital deaths with an HDP diagnosis code documented. During 2017-2019, the prevalence of HDP among delivery hospitalizations increased from 13.3% to 15.9%. The prevalence of pregnancy-associated hypertension increased from 10.8% in 2017 to 13.0% in 2019, while the prevalence of chronic hypertension increased from 2.0% to 2.3%. Prevalence of HDP was highest among delivery hospitalizations of non-Hispanic Black or African American (Black) women, non-Hispanic American Indian and Alaska Native (AI/AN) women, and women aged ≥35 years, residing in zip codes in the lowest median household income quartile, or delivering in hospitals in the South or the Midwest Census regions. Among deaths that occurred during delivery hospitalization, 31.6% had any HDP documented. Clinical guidance for reducing complications from HDP focuses on prompt identification and preventing progression to severe maternal complications through timely treatment (1). Recommendations for identifying and monitoring pregnant persons with hypertension include measuring blood pressure throughout pregnancy,(§) including self-monitoring. Severe complications and mortality from HDP are preventable with equitable implementation of strategies to identify and monitor persons with HDP (1) and quality improvement initiatives to improve prompt treatment and increase awareness of urgent maternal warning signs (2). |
Clinical Practice Changes in Monitoring Hypertension early in the COVID-19 Pandemic.
Robbins CL , Ford ND , Hayes DK , Ko JY , Kuklina E , Cox S , Ferre C , Loustalot F . Am J Hypertens 2022 35 (7) 596-600 BACKGROUND: Clinical practices can use telemedicine and other strategies (e.g., self-measured blood pressure [SMBP]) for remote monitoring of hypertension to promote control while decreasing risk of exposure to SARS-CoV-2, the virus that causes COVID-19. METHODS: The DocStyles survey collected data from primary care providers (PCPs), obstetricians-gynecologists (OB/GYNs), and nurse practitioners/physician assistants (NP/PAs) in fall 2020 (n=1,502). We investigated clinical practice changes for monitoring hypertension that were implemented early in the COVID-19 pandemic and examined differences by clinician and practice characteristics (p<0.05). RESULTS: Overall, 369 (24.6%) of clinicians reported their clinical practices made no changes in monitoring hypertension early in the pandemic, 884 (58.9%) advised patients to monitor blood pressure at home or a pharmacy, 699 (46.5%) implemented or increased use of telemedicine for blood pressure monitoring visits, and 545 (36.3%) reduced the frequency of office visits for blood pressure monitoring. Compared with NP/PAs, PCPs were more likely to advise SMBP monitoring (adjusted prevalence ratios (aPR) 1.28, 95% confidence intervals (CI) 1.11-1.47), implement or increase use of telemedicine (aPR 1.23, 95% CI 1.04-1.46) and reduce the frequency of office visits (aPR 1.37, 95% CI 1.11-1.70) for blood pressure monitoring, and less likely to report making no practice changes (aPR 0.63, 95% CI 0.51-0.77). CONCLUSIONS: We noted variation in clinical practice changes by clinician type and practice characteristics. Clinical practices may need additional support and resources to fully maximize telemedicine and other strategies for remote monitoring of hypertension during pandemics and other emergencies that can disrupt routine health care. |
Blood pressure control among non-Hispanic Black adults is lower than non-Hispanic White adults despite similar treatment with anti-hypertensive medication: NHANES 2013-2018
Hayes DK , Jackson SL , Li Y , Wozniak G , Tsipas S , Hong Y , Thompson-Paul AM , Wall HK , Gillespie C , Egan BM , Ritchey MD , Loustalot F . Am J Hypertens 2022 35 (6) 514-525 BACKGROUND: Controlled blood pressure can prevent or reduce adverse health outcomes. Social and structural determinants may contribute to the disparity that despite equivalent proportions on anti-hypertensive medication, non-Hispanic Black (Black) adults have lower blood pressure control and more cardiovascular events than non-Hispanic White (White) adults. METHODS: Data from 2013-2018 National Health and Nutrition Examination Survey were pooled to assess control among Black and White adults by anti-hypertensive medication use and selected characteristics using the 2017 American College of Cardiology/American Heart Association (ACC/AHA) Blood Pressure Guideline definition (systolic blood pressure <130mm Hg and diastolic blood pressure <80mm Hg) among 4,739 adults. RESULTS: Among those treated with anti-hypertensive medication, an estimated 34.9% of Black and 45.0% of White adults had controlled blood pressure. Control was lower for Black and White adults among most subgroups of age, sex, education, insurance status, usual source of care, and poverty-income ratio. Black adults had higher use of diuretics (28.5%--Black adults vs. 23.5%--White adults) and calcium channel blockers (24.2%--Black adults vs. 14.7%--White adults) compared to White adults. Control among Black adults was lower than White adults across all medication classes including diuretics (36.1%--Black adults vs. 47.3%--White adults), calcium channel blockers (30.2%--Black adults vs. 40.1%--White adults), and number of medication classes used. CONCLUSIONS: Sub-optimal blood pressure control rates and disparities warrant increased efforts to improve control, which could include addressing social and structural determinants along with emphasizing implementation of the 2017 ACC/AHA Blood Pressure Guideline into clinical practice. |
COVID-19 Vaccine Provider Access and Vaccination Coverage Among Children Aged 5-11 Years - United States, November 2021-January 2022.
Kim C , Yee R , Bhatkoti R , Carranza D , Henderson D , Kuwabara SA , Trinidad JP , Radesky S , Cohen A , Vogt TM , Smith Z , Duggar C , Chatham-Stephens K , Ottis C , Rand K , Lim T , Jackson AF , Richardson D , Jaffe A , Lubitz R , Hayes R , Zouela A , Kotulich DL , Kelleher PN , Guo A , Pillai SK , Patel A . MMWR Morb Mortal Wkly Rep 2022 71 (10) 378-383 On October 29, 2021, the Pfizer-BioNTech pediatric COVID-19 vaccine received Emergency Use Authorization for children aged 5-11 years in the United States.() For a successful immunization program, both access to and uptake of the vaccine are needed. Fifteen million doses were initially made available to pediatric providers to ensure the broadest possible access for the estimated 28 million eligible children aged 5-11 years, especially those in high social vulnerability index (SVI)() communities. Initial supply was strategically distributed to maximize vaccination opportunities for U.S. children aged 5-11 years. COVID-19 vaccination coverage among persons aged 12-17 years has lagged (1), and vaccine confidence has been identified as a concern among parents and caregivers (2). Therefore, COVID-19 provider access and early vaccination coverage among children aged 5-11 years in high and low SVI communities were examined during November 1, 2021-January 18, 2022. As of November 29, 2021 (4 weeks after program launch), 38,732 providers were enrolled, and 92% of U.S. children aged 5-11 years lived within 5 miles of an active provider. As of January 18, 2022 (11 weeks after program launch), 39,786 providers had administered 13.3 million doses. First dose coverage at 4 weeks after launch was 15.0% (10.5% and 17.5% in high and low SVI areas, respectively; rate ratio [RR]=0.68; 95% CI=0.60-0.78), and at 11 weeks was 27.7% (21.2% and 29.0% in high and low SVI areas, respectively; RR=0.76; 95% CI=0.68-0.84). Overall series completion at 11 weeks after launch was 19.1% (13.7% and 21.7% in high and low SVI areas, respectively; RR=0.67; 95% CI=0.58-0.77). Pharmacies administered 46.4% of doses to this age group, including 48.7% of doses in high SVI areas and 44.4% in low SVI areas. Although COVID-19 vaccination coverage rates were low, particularly in high SVI areas, first dose coverage improved over time. Additional outreach is critical, especially in high SVI areas, to improve vaccine confidence and increase coverage rates among children aged 5-11 years. |

Chest 2022 162 (1) 256-264 BACKGROUND: In 2019, the United States experienced a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI). More than half of these patients required admission to an intensive care unit (ICU). METHODS: To synthesize information critical to pulmonary/critical care specialists in the care of patients with EVALI, we examined data available from patients hospitalized with EVALI between August 2019 and January 2020; reviewed the clinical course and critical care experience with those patients admitted to the ICU; and compiled opinion of national experts. RESULTS: Of the 2,708 confirmed or probable EVALI patients requiring hospitalization as of January 21, 2020, 1,604 (59.2%) had data available on ICU admission; of these, 705 (44.0%) were admitted to the ICU and are included in this analysis. The majority of ICU patients required respiratory support (88.5%), and in severe cases required intubation (36.1%), or extracorporeal membrane oxygenation (ECMO) (6.7%). The majority (93.0%) of these ICU patients survived to discharge. Review of the clinical course and expert opinion provided insight into: imaging; considerations for bronchoscopy; medical treatment, including use of empiric antibiotics, antivirals, and corticosteroids; respiratory support, including considerations for intubation, positioning maneuvers, and ECMO; and patient outcomes. CONCLUSIONS: Review of the clinical course of EVALI patients requiring ICU admission and compilation of expert opinion provided critical insight into pulmonary/critical care-specific considerations for this patient population. As a large proportion of patients hospitalized with EVALI required ICU admission, it is important to remain prepared to care for patients with EVALI. |

Neuroepidemiology 2021 55 (3) 1-10 INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a fatal, neuromuscular disease with no cure. ALS incidence rates have not been assessed specifically in Ohio, yet the state contains both metropolitan and rural areas with a variety of environmental factors that could contribute to disease etiology. We report the incidence of ALS in Ohio residents diagnosed from October 2016 through September 2018. METHODS: We engaged practitioners from 9 Ohio sites to identify newly diagnosed ALS patients and to complete case report forms with demographic and clinical information. ALS was diagnosed according to the Awaji criteria and classified as either definite, probable, or possible. We developed a method to estimate missing cases using a Poisson regression model to impute cases in counties with evidence of undercounting. RESULTS: We identified 333 newly diagnosed ALS patients residing in Ohio during the 2-year index period and found incidence rates varied in the 88 state counties. After incorporating the estimated 27% of missing cases, the corrected crude annual incidence was 1.96/100,000 person-years, and the age- and gender-standardized incidence was 1.71/100,000 person-years (standardized to the 2010 US census). DISCUSSION/CONCLUSION: The estimated Ohio incidence of ALS is overall similar to that reported in other states in the USA. This study reveals a geospatial variation in incidence within the state, and areas with higher rates warrant future investigation. |
Estimating and Characterizing COVID-19 Deaths, Puerto Rico, March-July 2020.

Public Health Rep 2021 136 (3) 354-360 OBJECTIVES: Using the Council of State and Territorial Epidemiologists (CSTE) classification guidelines, we characterized coronavirus disease 2019 (COVID-19)-associated confirmed and probable deaths in Puerto Rico during March-July 2020. We also estimated the total number of possible deaths due to COVID-19 in Puerto Rico during the same period. METHODS: We described data on COVID-19-associated mortality, in which the lower bound was the sum of confirmed and probable COVID-19 deaths and the upper bound was excess mortality, estimated as the difference between observed deaths and average expected deaths. We obtained data from the Puerto Rico Department of Health COVID-19 Mortality Surveillance System, the Centers for Disease Control and Prevention's National Electronic Disease Surveillance System Base System, and the National Center for Health Statistics. RESULTS: During March-July 2020, 225 COVID-19-associated deaths were identified in Puerto Rico (119 confirmed deaths and 106 probable deaths). The median age of decedents was 73 (interquartile range, 59-83); 60 (26.7%) deaths occurred in the Metropolitana region, and 140 (62.2%) deaths occurred among men. Of the 225 decedents, 180 (83.6%) had been hospitalized and 93 (41.3%) had required mechanical ventilation. Influenza and pneumonia (48.0%), sepsis (28.9%), and respiratory failure (27.1%) were the most common conditions contributing to COVID-19 deaths based on death certificates. Based on excess mortality calculations, as many as 638 COVID-19-associated deaths could have occurred during the study period, up to 413 more COVID-19-associated deaths than originally reported. CONCLUSIONS: Including probable deaths per the CSTE guidelines and monitoring all-cause excess mortality can lead to a better estimation of COVID-19-associated deaths and serve as a model to enhance mortality surveillance in other US jurisdictions. |
