J Food Prot 2024 100413 In 2022, the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), U.S. state and local partners, the Public Health Agency of Canada (PHAC), and the Canadian Food Inspection Agency (CFIA), conducted a bi-national sample-initiated retrospective outbreak investigation (SIROI) of Listeria monocytogenes illnesses linked to enoki mushrooms. The FDA and CDC investigated the first known L. monocytogenes outbreak linked to enoki mushrooms from 2016-2020, making the 2022 outbreak the second time this pathogen-commodity pair was investigated by FDA and CDC. The 2022 outbreak included six ill people, all of whom were hospitalized. Epidemiologic, laboratory, and traceback evidence led to multiple public health actions, including voluntary recalls by firms, public communications about the outbreak, and FDA's country-wide Import Alert for enoki mushrooms from China. This SIROI illustrates the importance of surveillance sampling, national and international coordination of efforts, and rapid information sharing to identify and stop foodborne outbreaks on a global scale. To reduce the risk of listeriosis illnesses linked to contaminated enoki mushrooms, public health and regulatory agencies in the United States and Canada remain committed to conducting comprehensive surveillance for Listeria in foods and in people, efficiently investigating identified outbreaks, and implementing control measures to potentially minimize the impact of future outbreaks. |
Associations between health-related social needs and cardiovascular health among US adults
Zhang Z , Jackson SL , Thompson-Paul AM , Yin X , Merritt RK , Coronado F . J Am Heart Assoc 2024 e035863 BACKGROUND: Unfavorable health-related social needs (HRSNs) have the potential to worsen health and well-being and drive health disparities. Its associations with cardiovascular health (CVH), assessed by Life's Essential 8, have not been comprehensively examined among US adults. METHODS AND RESULTS: We used the National Health and Nutrition Examination Survey 2011 to March 2020 data for adults aged ≥20 years. We grouped Life's Essential 8 scores as low (0-49), moderate (50-79), and high (80-100) CVH. We identified 8 unfavorable HRSNs and assigned a value of 1 for the unfavorable status of each. The number of unfavorable HRSNs was summed and ranged from 0 to 8, with higher numbers indicating more unfavorable HRSNs. We used multivariable linear and multinomial logistic regression to examine the association between HRSNs and CVH. A total of 14 947 participants were included (n=7340 male [49.3%]; mean [SE] age, 46.4 [0.35] years). A higher number of unfavorable HRSNs were associated with worse CVH: comparing adults with unfavorable HRSNs of 1-2, 3-4, and ≥5 to those with none, the fully adjusted prevalence ratios (95% CI) for low CVH were 1.42 (1.17-1.73), 2.11 (1.69-2.63), and 2.42 (1.90-3.08), respectively. The corresponding prevalence ratios (95% CI) for high CVH were 0.77 (0.68-0.87), 0.58 (0.49-0.67), and 0.46 (0.38-0.55). The associations were consistent across subgroups and in sensitivity analyses. CONCLUSIONS: There was a graded association between unfavorable HRSNs and a higher prevalence of low CVH or lower prevalence of high CVH. Public health interventions targeting HRSNs might reduce health disparities and promote CVH. |

Knight D , Monger M , Phillips K , Antar A , Baral S , Stockman JK , Nunn A , Chan P , Mayer K , Mena L , Kershaw T , Willie TC . Womens Health (Lond) 2024 20 17455057241296905 BACKGROUND: Stigma and lack of social support are barriers to HIV prevention, especially among cisgender Black women in the United States. While HIV pre-exposure prophylaxis (PrEP) can decrease HIV transmission, PrEP initiation and adherence remains low among Black women, especially in the U.S. South. OBJECTIVES: The purpose of this study was to characterize experiences with stigma and social support among PrEP-naïve and PrEP-experienced Black cisgender women in Mississippi. DESIGN: Qualitative study in which semi-structured interviews and focus groups were conducted. METHODS: We purposively recruited PrEP-naïve cisgender Black women who met PrEP indications to participate in focus groups and all PrEP-experienced cisgender Black women at a sexual health clinic in Jackson, Mississippi to participate in one-on-one semi-structured interviews. Inductive thematic analysis was used to analyze focus group and interview transcripts. RESULTS: A total of 37 PrEP-naïve Black cisgender women participated across 6 focus groups and 8 PrEP-experienced cisgender Black women completed semi-structured interviews. Four themes were identified: (1) the intersection of gendered racism, discrimination, and HIV stigma, (2) enacted and anticipated PrEP stigma, (3) stigma mitigation strategies and PrEP adherence, and (4) social support's role in PrEP initiation and adherence. PrEP-naïve and -experienced Black women discussed the negative consequence that sexual stigmatization and gendered racism has on HIV testing. PrEP-naïve Black women discussed how HIV stigma decreases PrEP initiation. Conversely, PrEP-experienced Black women were able to identify strategies they utilized to mitigate stigma. PrEP-experienced Black women discussed how differing levels of social support impact their PrEP use. CONCLUSION: Improving social support and stigma mitigation strategies could help improve PrEP initiation and adherence among cisgender Black women at-risk of acquiring HIV in the U.S. South. Educating communities on PrEP, and training providers on stigma-mitigating strategies when serving Black women in the U.S. South who are seeking HIV prevention is paramount. | PrEP initiation and adherence among Black cisgender women in Mississippi: The role of HIV and PrEP stigma and social supportWhy was the study done?Stigma and lack of social support have been demonstrated as barriers to HIV prevention, especially among cisgender Black women in the United States (U.S.). While HIV pre-exposure prophylaxis (PrEP), a HIV prevention medication, has the ability to decrease HIV transmission, rates of starting PrEP remain low among Black women, especially in the U.S. South. Improving PrEP programs for US Black women calls for understanding how stigma and social support impact PrEP use among Black women.What did the researchers do?We recruited cisgender Black women who was eligible for PrEP but have never taken PrEP (PrEP-naïve) to participate in focus groups and cisgender Black women who have taken PrEP (PrEP-experienced) to participate in one-on-one in-depth interviews from healthcare clinics in Jackson, Mississippi. Inductive thematic analysis was used to analyze focus group and interview transcripts.What did the researchers find?A total of 37 Black cisgender women across six groups participated in focus groups and eight cisgender Black women were interviewed. PrEP-naïve women reported: · HIV stigma in the community, which can lead to anticipated PrEP stigma · Experiencing sex-based sexual stigmatization at provider’s offices when seeking HIV testing PrEP-experienced Black women reported: Experiencing stigma when disclosing their PrEP use, such as their family and friends thinking that the woman and/or her partner is living with HIV. PrEP-experienced Black women who were in serodifferent partnership and had others in their network who knew about PrEP received support to take PrEP.What do the findings mean?Improving social support and stigma mitigation strategies could help improve PrEP initiation and adherence among cisgender Black women at-risk of acquiring HIV in the U.S. South. This includes educating communities on HIV and PrEP, and training providers on stigma-mitigating strategies when serving Black women in the U.S. South. | eng |
JYNNEOS vaccine safety surveillance in the vaccine safety datalink during the 2022 mpox outbreak in the United States
Duffy J , Yih WK , Walton K , DeSilva MB , Glanz JM , Hambidge SJ , Jackson LA , Klein NP , Lewin BJ , Naleway AL , Sundaram ME , Maro JC , Weintraub E . Infection 2024 BACKGROUND: The JYNNEOS vaccine (two doses given 28 days apart) was recommended in the United States for people at high risk of exposure to monkeypox virus during the 2022 mpox outbreak. Our objective was to assess the safety of JYNNEOS using two complementary epidemiologic methods. METHODS: This observational cohort included patients of eight large integrated healthcare organizations who received JYNNEOS. Adverse events were identified using ICD-10 coded diagnoses assigned to medical visits. The first analysis used standardized incidence ratios (SIR) to compare the observed incidence of ten prespecified adverse events of special interest (AESI) during the 28 days after receipt of each dose of JYNNEOS to the expected incidence adjusted for several risk factors. The second analysis used tree-based data mining to identify temporal clustering of cases for more than 60,000 diagnoses and diagnosis groups within 70-days after JYNNEOS dose 1 administration. RESULTS: The SIR analysis included 53,583 adults who received JYNNEOS dose 1 and 38,206 who received dose 2. Males received 92% of the doses. There were no statistically significant elevated SIRs for any of the ten AESI. The tree-based data mining analysis included 36,912 vaccinees. Analysis of diagnoses in inpatient, emergency department, and outpatient settings identified statistically significant clusters of visits for rash and unspecified adverse effects. CONCLUSIONS: No new or unexpected safety concerns were identified. AESI did not occur more frequently than expected by chance alone. Non-serious medically attended adverse events, such as rash, have been previously reported and occurred infrequently. |
Transgender Latinas' perspectives on HIV PrEP uptake, condom use, and medically supervised gender-affirming hormone therapy: Insights from ChiCAS Qualitative Interviews
Smart BD , Alonzo J , Mann-Jackson L , Aviles LR , Tanner AE , Galindo CA , Bessler PA , Courtenay-Quirk C , Garcia M , Aguilar-Palma SK , Reboussin BA , Rhodes SD . AIDS Educ Prev 2024 36 (5) 369-386 There is a dearth of HIV prevention behavioral interventions for transgender Latinas, despite this population's HIV risk. ChiCAS (Chicas Creando Acceso a la Salud) is an intervention to increase PrEP, condom, and gender-affirming hormone therapy (GAHT) use among transgender Latinas. To inform future work, semistructured interviews were conducted postintervention with 28 ChiCAS participants. Thematic analysis with inductive coding was used. Six themes emerged: (1) health-related priorities include sexual health and avoiding discrimination; (2) safe and collaborative community is of high importance; (3) interactive education with time for sharing stories and discussion was valued; (4) PrEP uptake was facilitated through awareness and health care navigation; (5) accessing GAHT depends on cost, clinic location, and individual goals; (6) ChiCAS could be improved with more PrEP/GAHT details and social connection. Interventions with goals similar to those of ChiCAS should prioritize building community, PrEP and GAHT education tailored to participants' needs, and emphasize health care options available locally. |
Antihypertensive medication adherence and medical costs, health care use, and labor productivity among people with hypertension
Lee JS , Segura Escano R , Therrien NL , Kumar A , Bhatt A , Pollack LM , Jackson SL , Luo F . J Am Heart Assoc 2024 13 (21) e037357 BACKGROUND: Hypertension affects nearly half of US adults yet remains inadequately controlled in over three-quarters of these cases. This study aimed to assess the association between adherence to antihypertensive medications and total medical costs, health care use, and productivity-related outcomes. METHODS AND RESULTS: We conducted cross-sectional analyses using MarketScan databases, which included individuals aged 18 to 64 years with noncapitated health insurance plans in 2019. Adherence was defined as ≥80% medication possession ratio for prescribed antihypertensive medications. We used a generalized linear model to estimate total medical costs, a negative binomial model to estimate health care use (emergency department visits and inpatient admissions), an exponential hurdle model to estimate productivity-related outcomes (number of sick absences, short-term disability, long-term disability), and a 2-part model to estimate productivity-related costs in 2019 US dollars. All models were adjusted for age, sex, urbanicity, census region, and comorbidities. We reported average marginal effects for outcomes related to antihypertensive medication adherence. Among 379 503 individuals with hypertension in 2019, 54.4% adhered to antihypertensives. Per person, antihypertensive medication adherence was associated with $1441 lower total medical costs, $11 lower sick absence costs, $291 lower short-term disability costs, and $69 lower long-term disability costs. Per 1000 individuals, medication adherence was associated with lower health care use, including 200 fewer emergency department visits and 90 fewer inpatient admissions, and productivity-related outcomes, including 20 fewer sick absence days and 442 fewer short-term disability days. CONCLUSIONS: Adherence to antihypertensives was consistently associated with lower total medical costs, reduced health care use, and improved productivity-related outcomes. |

Masters TL , Toney NC , Ewing TO , McAllister G , Mathis MH , Grigg C , Magill SS , Jackson KA , Byram R , See I , Salfinger M , Barter D , Johnston H , Lynfield R , Vagnone PS , Tourdot L , Anderson BJ , Dumyati G , Pierce R , Lutgring JD , Gargis A , McKay S . J Infect Dis 2024 BACKGROUND: Nontuberculous mycobacteria (NTM) cause pulmonary and extrapulmonary infections. Although isolation of NTM from clinical specimens has increased nationally, few studies delineated the molecular characteristics of extrapulmonary NTM. METHODS: Extrapulmonary isolates were collected by four Emerging Infections Program sites from October 2019 to March 2020 and underwent laboratory characterization, including matrix-assisted laser desorption ionization-time of flight mass spectrometry, Sanger DNA sequencing, and whole genome sequencing. Bioinformatics analyses were employed to identify species, sequence types (STs), antimicrobial resistance (AR), and virulence genes; isolates were further characterized by phylogenetic analyses. RESULTS: Among 45 isolates, the predominant species were Mycobacterium avium (n=20, 44%), Mycobacterium chelonae (n=7, 16%), and Mycobacterium fortuitum (n=6, 13%). The collection represented 31 STs across 10 species; the most common ST was ST11 (M. avium, n=7). Mycobacterium fortuitum and Mycobacterium abscessus isolates harbored multiple genes conferring resistance to aminoglycosides, beta-lactams, and macrolides. No known AR mutations were detected in rpoB, 16S, or 23S rRNAs. Slow-growing NTM species harbored multiple virulence genes including type-VII secretion components, adhesion factors, and phospholipase C. CONCLUSION: Continued active laboratory- and population-based surveillance will further inform the prevalence of NTM species and STs, monitor emerging clones, and allow AR characterization. |
Blood pressure cuff sizes for pregnant women in the United States: Findings from the National Health and Nutrition Examination Survey
Shahi S , Streeter TE , Wall HK , Zhou W , Kuklina EV , Jackson SL . Am J Hypertens 2024 BACKGROUND: The use of correctly-sized blood pressure (BP) cuffs is important to ensure accurate measurement and effective management of hypertension. The goals of this study were to determine the proportions of pregnant women that would require small, adult, large, and extra-large (XL) cuff sizes, and to examine the demographic characteristics associated with need for a large or XL cuff. METHODS: This cross-sectional study analyzed 1,176 pregnant women (≥18 years) included in the National Health and Nutrition Examination Survey (NHANES) 1999-2006 cycles. Recommended BP cuff sizes, based on American Heart Association recommendations, were categorized by mid-arm circumference: small adult (≤26 cm), adult (>26 to ≤34 cm), large (>34 to ≤44 cm), and extra-large (XL) (>44 cm). RESULTS: Among US pregnant women, recommended cuff sizes were: 17.9% small adult, 57.0% adult, and 25.1% for large or XL. About 38.5% of non-Hispanic Black, 21.6% of Mexican American and 21.0% of non-Hispanic White pregnant women required a large or XL cuff. About 81.8% of women in the highest quartile for BMI required large or XL cuffs, which was significantly higher than women in other quartiles. CONCLUSION: Roughly one out of every four pregnant women required large or XL BP cuffs. The requirement for large or XL cuffs was highest among non-Hispanic Black women and women with the highest BMI. For pregnant women, measuring the arm circumference and selecting an appropriately-sized cuff is important to facilitate accurate blood pressure monitoring and hypertension management. |
Rat-tail models for studying hand-arm vibration syndrome: A comparison between living and cadaver rat tails
Warren CM , Xu XS , Jackson M , McKinney WG , Wu JZ , Welcome DE , Waugh S , Chapman P , Sinsel EW , Service S , Krajnak K , Dong RG . Vib 2024 7 (3) 722-737 Over-exposure of the hand-arm system to intense vibration and force over time may cause degeneration of the vascular, neurological, and musculoskeletal systems in the fingers. A novel animal model using rat tails has been developed to understand the health effects on human fingers exposed to vibration and force when operating powered hand tools or workpieces. The biodynamic responses, such as vibration stress, strain, and power absorption density, of the rat tails can be used to help evaluate the health effects related to vibration and force and to establish a dose-effect relationship. While the biodynamic responses of cadaver rat tails have been investigated, the objective of the current study was to determine whether the biodynamic responses of living rat tails are different from those of cadaver rat tails, and whether the biodynamic responses of both living and cadaver tails change with exposure duration. To make direct comparisons, the responses of both cadaver and living rat tails were examined on four different testing stations. The transfer function of each tail under a given contact force (2 N) was measured at each frequency in the one-third octave bands from 20 to 1000 Hz, and used to calculate the mechanical system parameters of the tails. The transfer functions were also measured at different exposure durations to determine the time dependency of the response. Differences were observed in the vibration biodynamic responses between living and cadaver tails, but the general trends were similar. The biodynamic responses of both cadaver and living rat tails varied with exposure duration. © 2024 by the authors. |
Cardiovascular disease mortality trends, 2010-2022: An update with final data
Woodruff RC , Tong X , Loustalot F , Khan SS , Shah NS , Jackson SL , Vaughan AS . Am J Prev Med 2024 INTRODUCTION: Age-adjusted mortality rates (AAMR) for cardiovascular diseases (CVD) increased in 2020 and 2021, and provisional data indicated an increase in 2022, resulting in substantial excess CVD deaths during the COVID-19 pandemic. Updated estimates using final data for 2022 are needed. METHODS: The National Vital Statistics System's final Multiple Cause of Death files were analyzed in 2024 to calculate AAMR from 2010 to 2022 and excess deaths from 2020 to 2022 for US adults aged ≥35 years, with CVD as the underlying cause of death. RESULTS: The CVD AAMR among adults aged ≥35 years in 2022 was 434.6 deaths per 100,000 (95% CI: 433.8, 435.5), which was lower than in 2021 (451.8 deaths per 100,000; 95% CI: 450.9, 452.7). The most recent year with a similarly high CVD AAMR as in 2022 was 2012 (434.7 deaths per 100,000 population, 95% CI: 433.8, 435.7). The CVD AAMR for 2022 calculated using provisional data over-estimated the AAMR calculated using final data by 4.6% (95% CI: 4.3%, 4.9%) or 19.9 (95% CI: 18.6, 21.2) deaths per 100,000 population. From 2020 to 2022, an estimated 190,661 (95% CI: 158,139, 223,325) excess CVD deaths occurred. CONCLUSIONS: In 2022, the CVD AAMR among adults aged ≥35 years did not increase, but rather declined from a peak in 2021, signaling improvements in adverse mortality trends that began in 2020, amid the COVID-19 pandemic. However, the 2022 CVD AAMR remains higher than observed before the COVID-19 pandemic, indicating an ongoing need for cardiovascular disease prevention, detection, and management. |

Jackson BD , Miernyk K , Steinberg J , Beaudry J , Christensen L , Chukwuma U , Clichee D , Damon S , Farrenkopf BA , Hurley C , Luna J , Simons B , Singleton R , Thomas M , VanDeRiet D , Weatherholtz R , Zeger S , Zylstra S , Keck J , Hammitt LL . Pediatrics 2024 OBJECTIVES: American Indian and Alaska Native (AI/AN) infants historically experienced a disproportionate burden of invasive Haemophilus influenzae type b (Hib) disease, especially early in life. PedvaxHIB vaccine is preferentially recommended for AI/AN infants because it elicits protective antibody levels postdose 1. Vaxelis, a hexavalent vaccine that contains the same Hib conjugate as PedvaxHIB but at lower concentration, is recommended for US children, but postdose 1 Hib immunogenicity data are needed to inform whether a preferential recommendation should be made for AI/AN infants. METHODS: We conducted a phase IV randomized, open-label, noninferiority trial comparing postdose 1 immunogenicity of Vaxelis to PedvaxHIB in AI/AN infants. Participants were randomized to receive a primary series of PedvaxHIB or Vaxelis. Serum samples collected 30 days postdose 1 were tested for anti-Hib immunoglobulin G antibody by enzyme-linked immunosorbent assay. The anti-Hib immunoglobulin G geometric mean concentration (GMC) ratio (Vaxelis/PedvaxHIB) was estimated by constrained longitudinal data analysis. Noninferiority was defined a priori as the lower bound of the 95% confidence interval (CI) of the GMC ratio ≥0.67. RESULTS: A total of 327 of the 333 infants enrolled in the study were included in the per-protocol analysis. The postdose 1 anti-Hib GMC was 0.41 µg/mL (95% CI 0.33-0.52) in the Vaxelis group (n = 152) and 0.39 µg/mL (95% CI 0.31-0.50) in the PedvaxHIB group (n = 146). The constrained longitudinal data analysis GMC ratio was 1.03 (95% CI 0.76-1.39). CONCLUSIONS: Postdose 1 immunogenicity of Vaxelis was noninferior to PedvaxHIB. Our findings support the use of Vaxelis in AI/AN children, a population with elevated risk of Hib disease. |
Hypertension-associated expenditures among privately insured US adults in 2021
Kumar A , He S , Pollack LM , Lee JS , Imoisili O , Wang Y , Kompaniyets L , Luo F , Jackson SL . Hypertension 2024 BACKGROUND: There are no recent estimates for hypertension-associated medical expenditures. This study aims to estimate hypertension-associated incremental medical expenditures among privately insured US adults. METHODS: We conducted a retrospective cohort study using IQVIA's Ambulatory Electronic Medical Records-US data set linked with PharMetrics Plus claims data. Among privately insured adults aged 18 to 64 years, hypertension was identified as having ≥1 diagnosis code or ≥2 blood pressure measurements of ≥140/90 mm Hg, or ≥1 antihypertensive medication in 2021. Annual total expenditures (in 2021 $US) were estimated using a generalized linear model with gamma distribution and log-link function adjusting for demographic characteristics and cooccurring conditions. Out-of-pocket expenditures were estimated using a 2-part model that included logistic and generalized linear model regression. Overlap propensity score weights from logistic regression were used to obtain a balanced sample on hypertension status. RESULTS: Among the 393 018 adults, 156 556 (40%) were identified with hypertension. Compared with individuals without hypertension, those with hypertension had $2926 (95% CI, $2681-$3170) higher total expenditures and $328 (95% CI, $300-$355) higher out-of-pocket expenditures. Adults with hypertension had higher total inpatient ($3272 [95% CI, $1458-$5086]) and outpatient ($2189 [95% CI, $2009-$2369]) expenditures when compared with those without hypertension. Hypertension-associated incremental total expenditures were higher for women ($3242 [95% CI, $2915-$3569]) than for men ($2521 [95% CI, $2139-$2904]). CONCLUSIONS: Among privately insured US adults, hypertension was associated with higher medical expenditures, including higher inpatient and out-of-pocket expenditures. These findings may help assess the economic value of interventions effective in preventing hypertension. |
Alzheimer's disease and related dementia diagnoses among American Indian and Alaska Native adults aged ≥45 years, Indian Health Service System, 2016-2020
Apostolou A , Kennedy JL , Person MK , Jackson EMJ , Finke B , McGuire LC , Matthews KA . J Am Geriatr Soc 2024 BACKGROUND: Alzheimer's disease is the most common type of dementia and is responsible for up to 80% of dementia diagnoses and is the sixth leading cause of death in the United States. An estimated 38,000 American Indian/Alaska Native (AI/AN) people aged ≥65 years were living with Alzheimer's disease and related dementias (ADRD) in 2020, a number expected to double by 2030 and quadruple by 2050. Administrative healthcare data from the Indian Health Service (IHS) were used to estimate ADRD among AI/AN populations. METHODS: Administrative IHS healthcare data from federal fiscal years 2016 to 2020 from the IHS National Data Warehouse were used to calculate the count and rate per 100,000 AI/AN adults aged ≥45 years with at least one ADRD diagnosis code on their medical record. RESULTS: This study identified 12,877 AI/AN adults aged ≥45 years with an ADRD diagnosis code, with an overall rate of 514 per 100,000. Of those, 1856 people were aged 45-64. Females were 1.2 times (95% confidence interval: 1.1-1.2) more likely than males to have a medical visit with an ADRD diagnosis code. CONCLUSIONS: Many AI/AN people with ADRD rely on IHS, tribal, and urban Indian health programs. The high burden of ADRD in AI/AN populations aged 45-64 utilizing IHS health services highlights the need for implementation of ADRD risk reduction strategies and assessment and diagnosis of ADRD in younger AI/AN populations. This study provides a baseline to assess future progress for efforts addressing ADRD in AI/AN communities. |
Impact of state telehealth parity laws for private payers on hypertension medication adherence before and during the COVID-19 pandemic
Zhang D , Lee JS , Popoola A , Lee S , Jackson SL , Pollack LM , Dong X , Therrien NL , Luo F . Circ Cardiovasc Qual Outcomes 2024 e010739 BACKGROUND: Telehealth has emerged as an effective tool for managing common chronic conditions such as hypertension, especially during the COVID-19 pandemic. However, the impact of state telehealth payment and coverage parity laws on hypertension medication adherence remains uncertain. METHODS: Data from the 2016 to 2021 Merative MarketScan Commercial Claims and Encounters Database were used to construct the study cohort, which included nonpregnant individuals aged 25 to 64 years with hypertension. We coded telehealth parity laws related to hypertension management in all 50 US states and the District of Columbia, distinguishing between payment and coverage parity laws. The primary outcomes were measures of antihypertension medication adherence: the average medication possession ratio; medication adherence (medication possession ratio ≥80%); and average number of days of drug supply. We used a generalized difference-in-differences design to examine the impact of these laws. RESULTS: Among 353 220 individuals (mean [SD] age, 49.5 (7.1) years; female, 45.55%), states with payment parity laws were significantly linked to increased average medication possession ratio by 0.43 percentage point (95% CI, 0.07-0.79), and an increase of 0.46 percentage point (95% CI, 0.06-0.92) in the probability of medication adherence. Payment parity laws also led to an average increase of 2.14 days (95% CI, 0.11-4.17) in prescription supply, after controlling for state-fixed effects, year-fixed effects, individual sociodemographic characteristics and state time-varying covariates including unemployment rates, gross domestic product per capita, and poverty rates. In contrast, coverage parity laws were associated with a 2.13-day increase (95% CI, 0.19-4.07) in days of prescription supply but did not significantly increase the average medication possession ratio or probability of medication adherence. CONCLUSIONS: State telehealth payment parity laws were significantly associated with greater medication adherence, whereas coverage parity laws were not. With the increasing adoption of telehealth parity laws across states, these findings may support policymakers in understanding potential implications on management of hypertension. |
Systemic and immunotoxicity induced by topical application of perfluoroheptane sulfonic acid (PFHpS) or perfluorooctane sulfonic acid (PFOS) in a murine model
Weatherly LM , Shane HL , Jackson LG , Lukomska E , Baur R , Cooper MP , Anderson SE . J Immunotoxicol 2024 21 (1) 2371868 Per- and polyfluoroalkyl substances (PFAS) are a large group of synthetic surfactants of over 12,000 compounds that are incorporated into numerous products for their chemical and physical properties. Studies have associated PFAS with adverse health effects. Although there is a high potential for dermal exposure, these studies are lacking. The present study evaluated the systemic and immunotoxicity of subchronic 28- or 10-days of dermal exposure, respectively, to PFHpS (0.3125-2.5% or 7.82-62.5 mg/kg/dose) or PFOS (0.5% or 12.5 mg/kg/dose) in a murine model. Elevated levels of PFHpS were detected in the serum and urine, suggesting that absorption is occurring through the dermal route. PFHpS induced significantly increased relative liver weight, significantly decreased relative spleen and thymus weight, altered serum chemistries, and altered histopathology. Additionally, PFHpS significantly reduced the humoral immune response and altered immune subsets in the spleen, suggesting immunosuppression. Gene expression changes were observed in the liver, skin, and spleen of genes involved in fatty acid metabolism, necrosis, and inflammation. Immune-cell phenotyping identified significant decreases in B-cells and CD11b(+) monocyte and/or macrophages in the spleen along with decreases in eosinophils and dendritic cells in the skin. These findings support PFHpS absorption through the skin leading to liver damage and immune suppression. |
Pediatric lipid screening prevalence using nationwide electronic medical records
Thompson-Paul AM , Kraus EM , Porter RM , Pierce SL , Kompaniyets L , Sekkarie A , Goodman AB , Jackson SL . JAMA Netw Open 2024 7 (7) e2421724 IMPORTANCE: Universal screening to identify unfavorable lipid levels is recommended for US children aged 9 to 11 years and adolescents aged 17 to 21 years (hereafter, young adults); however, screening benefits in these individuals have been questioned. Current use of lipid screening and prevalence of elevated lipid measurements among US youths is not well understood. OBJECTIVE: To investigate the prevalence of ambulatory pediatric lipid screening and elevated or abnormal lipid measurements among US screened youths by patient characteristic and test type. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used data from the IQVIA Ambulatory Electronic Medical Record database and included youths aged 9 to 21 years with 1 or more valid measurement of height and weight during the observation period (2018-2021). Body mass index (BMI) was calculated and categorized using standard pediatric BMI percentiles (9-19 years) and adult BMI categories (≥20 years). The data were analyzed from October 6, 2022, to January 18, 2023. MAIN OUTCOMES AND MEASURES: Lipid measurements were defined as abnormal if 1 or more of the following test results was identified: total cholesterol (≥200 mg/dL), low-density lipoprotein cholesterol (≥130 mg/dL), very low-density lipoprotein cholesterol (≥31 mg/dL), non-high-density lipoprotein cholesterol (≥145 mg/dL), and triglycerides (≥100 mg/dL for children aged 9 years or ≥130 mg/dL for patients aged 10-21 years). After adjustment for age group, sex, race and ethnicity, and BMI category, adjusted prevalence ratios (aPRs) and 95% CIs were calculated. RESULTS: Among 3 226 002 youths (23.9% aged 9-11 years, 34.8% aged 12-16 years, and 41.3% aged 17-21 years; 1 723 292 females [53.4%]; 60.0% White patients, 9.5% Black patients, and 2.4% Asian patients), 11.3% had 1 or more documented lipid screening tests. The frequency of lipid screening increased by age group (9-11 years, 9.0%; 12-16 years, 11.1%; 17-21 years, 12.9%) and BMI category (range, 9.2% [healthy weight] to 21.9% [severe obesity]). Among those screened, 30.2% had abnormal lipid levels. Compared with youths with a healthy weight, prevalence of an abnormal result was higher among those with overweight (aPR, 1.58; 95% CI, 1.56-1.61), moderate obesity (aPR, 2.16; 95% CI, 2.14-2.19), and severe obesity (aPR, 2.53; 95% CI, 2.50-2.57). CONCLUSIONS AND RELEVANCE: In this cross-sectional study of prevalence of lipid screening among US youths aged 9 to 21 years, approximately 1 in 10 were screened. Among them, abnormal lipid levels were identified in 1 in 3 youths overall and 1 in 2 youths with severe obesity. Health care professionals should consider implementing lipid screening among children aged 9 to 11 years, young adults aged 17 to 21 years, and all youths at high cardiovascular risk. |

Prev Chronic Dis 2024 21 E49 BACKGROUND: Data modernization efforts to strengthen surveillance capacity could help assess trends in use of preventive services and diagnoses of new chronic disease during the COVID-19 pandemic, which broadly disrupted health care access. METHODS: This cross-sectional study examined electronic health record data from US adults aged 21 to 79 years in a large national research network (PCORnet), to describe use of 8 preventive health services (N = 30,783,825 patients) and new diagnoses of 9 chronic diseases (N = 31,588,222 patients) during 2018 through 2022. Joinpoint regression assessed significant trends, and health debt was calculated comparing 2020 through 2022 volume to prepandemic (2018 and 2019) levels. RESULTS: From 2018 to 2022, use of some preventive services increased (hemoglobin A(1c) and lung computed tomography, both P < .05), others remained consistent (lipid testing, wellness visits, mammograms, Papanicolaou tests or human papillomavirus tests, stool-based screening), and colonoscopies or sigmoidoscopies declined (P < .01). Annual new chronic disease diagnoses were mostly stable (6% hypertension; 4% to 5% cholesterol; 4% diabetes; 1% colonic adenoma; 0.1% colorectal cancer; among women, 0.5% breast cancer), although some declined (lung cancer, cervical intraepithelial neoplasia or carcinoma in situ, cervical cancer, all P < .05). The pandemic resulted in health debt, because use of most preventive services and new diagnoses of chronic disease were less than expected during 2020; these partially rebounded in subsequent years. Colorectal screening and colonic adenoma detection by age group aligned with screening recommendation age changes during this period. CONCLUSION: Among over 30 million patients receiving care during 2018 through 2022, use of preventive services and new diagnoses of chronic disease declined in 2020 and then rebounded, with some remaining health debt. These data highlight opportunities to augment traditional surveillance with EHR-based data. |

Kharbanda EO , DeSilva MB , Lipkind HS , Romitti PA , Zhu J , Vesco KK , Boyce TG , Daley MF , Fuller CC , Getahun D , Jackson LA , Williams JTB , Zerbo O , Weintraub ES , Vazquez-Benitez G . JAMA Pediatr 2024 IMPORTANCE: COVID-19 vaccination is recommended throughout pregnancy to prevent pregnancy complications and adverse birth outcomes associated with COVID-19 disease. To date, data on birth defects after first-trimester vaccination are limited. OBJECTIVE: To evaluate the associated risks for selected major structural birth defects among live-born infants after first-trimester receipt of a messenger RNA (mRNA) COVID-19 vaccine. DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective cohort study of singleton pregnancies with estimated last menstrual period (LMP) between September 13, 2020, and April 3, 2021, and ending in live birth from March 5, 2021, to January 25, 2022. Included were data from 8 health systems in California, Oregon, Washington, Colorado, Minnesota, and Wisconsin in the Vaccine Safety Datalink. EXPOSURES: Receipt of 1 or 2 mRNA COVID-19 vaccine doses in the first trimester, as part of the primary series. MAIN OUTCOMES AND MEASURES: Selected major structural birth defects among live-born infants, identified from electronic health data using validated algorithms, with neural tube defects confirmed via medical record review. RESULTS: Among 42 156 eligible pregnancies (mean [SD] maternal age, 30.9 [5.0] years) 7632 (18.1%) received an mRNA COVID-19 vaccine in the first trimester. Of 34 524 pregnancies without a first-trimester COVID-19 vaccination, 2045 (5.9%) were vaccinated before pregnancy, 13 494 (39.1%) during the second or third trimester, and 18 985 (55.0%) were unvaccinated before or during pregnancy. Compared with pregnant people unvaccinated in the first trimester, those vaccinated in the first trimester were older (mean [SD] age, 32.3 [4.5] years vs 30.6 [5.1] years) and differed by LMP date. After applying stabilized inverse probability weighting, differences in baseline characteristics between vaccinated and unvaccinated pregnant persons in the first trimester were negligible (standardized mean difference <0.20). Selected major structural birth defects occurred in 113 infants (1.48%) after first-trimester mRNA COVID-19 vaccination and in 488 infants (1.41%) without first-trimester vaccine exposure; the adjusted prevalence ratio was 1.02 (95% CI, 0.78-1.33). In secondary analyses, with major structural birth defect outcomes grouped by organ system, no significant differences between infants vaccinated or unvaccinated in the first trimester were identified. CONCLUSIONS AND RELEVANCE: In this multisite cohort study, among live-born infants, first-trimester mRNA COVID-19 vaccine exposure was not associated with an increased risk for selected major structural birth defects. |
Validation of Multi-state EHR-Based Network for Disease Surveillance (MENDS) Data and implications for improving data quality and representativeness
Hohman KH , Klompas M , Zambarano B , Wall HK , Jackson SL , Kraus EM . Prev Chronic Dis 2024 21 E43 INTRODUCTION: Surveillance modernization efforts emphasize the potential use of electronic health record (EHR) data to inform public health surveillance and prevention. However, EHR data streams vary widely in their completeness, accuracy, and representativeness. METHODS: We developed a validation process for the Multi-State EHR-Based Network for Disease Surveillance (MENDS) pilot project to identify and resolve data quality issues that could affect chronic disease prevalence estimates. We examined MENDS validation processes from December 2020 through August 2023 across 5 data-contributing organizations and outlined steps to resolve data quality issues. RESULTS: We identified gaps in the EHR databases of data contributors and in the processes to extract, map, integrate, and analyze their EHR data. Examples of source-data problems included missing data on race and ethnicity and zip codes. Examples of data processing problems included duplicate or missing patient records, lower-than-expected volumes of data, use of multiple fields for a single data type, and implausible values. CONCLUSION: Validation protocols identified critical errors in both EHR source data and in the processes used to transform these data for analysis. Our experience highlights the value and importance of data validation to improve data quality and the accuracy of surveillance estimates that use EHR data. The validation process and lessons learned can be applied broadly to other EHR-based surveillance efforts. |

Hechter RC , Qian L , Liu IA , Sy LS , Ryan DS , Xu S , Williams JTB , Klein NP , Kaiser RM , Liles EG , Glanz JM , Jackson LA , Sundaram ME , Weintraub ES , Tseng HF . JAMA Netw Open 2024 7 (6) e2415220 IMPORTANCE: People with HIV (PWH) may be at increased risk for severe outcomes with COVID-19 illness compared with people without HIV. Little is known about COVID-19 vaccination coverage and factors associated with primary series completion among PWH. OBJECTIVES: To evaluate COVID-19 vaccination coverage among PWH and examine sociodemographic, clinical, and community-level factors associated with completion of the primary series and an additional primary dose. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study used electronic health record data to assess COVID-19 vaccination information from December 14, 2020, through April 30, 2022, from 8 health care organizations of the Vaccine Safety Datalink project in the US. Participants were adults diagnosed with HIV on or before December 14, 2020, enrolled in a participating site. MAIN OUTCOMES AND MEASURES: The percentage of PWH with at least 1 dose of COVID-19 vaccine and PWH who completed the COVID-19 vaccine primary series by December 31, 2021, and an additional primary dose by April 30, 2022. Rate ratios (RR) and 95% CIs were estimated using Poisson regression models for factors associated with completing the COVID-19 vaccine primary series and receiving an additional primary dose. RESULTS: Among 22 058 adult PWH (mean [SD] age, 52.1 [13.3] years; 88.8% male), 90.5% completed the primary series by December 31, 2021. Among 18 374 eligible PWH who completed the primary series by August 12, 2021, 15 982 (87.0%) received an additional primary dose, and 4318 (23.5%) received a booster dose by April 30, 2022. Receipt of influenza vaccines in the last 2 years was associated with completion of the primary series (RR, 1.17; 95% CI, 1.15-1.20) and an additional primary dose (RR, 1.61; 95% CI, 1.54-1.69). PWH with uncontrolled viremia (HIV viral load ≥200 copies/mL) (eg, RR, 0.90 [95% CI, 0.85-0.95] for viral load 200-10 000 copies/mL vs undetected or <200 copies/mL for completing the primary series) and Medicaid insurance (eg, RR, 0.89 [95% CI, 0.87-0.90] for completing the primary series) were less likely to be fully vaccinated. By contrast, greater outpatient utilization (eg, RR, 1.07 [95% CI, 1.05-1.09] for ≥7 vs 0 visits for primary series completion) and residence in counties with higher COVID-19 vaccine coverage (eg, RR, 1.06 [95% CI, 1.03-1.08] for fourth vs first quartiles for primary series completion) were associated with primary series and additional dose completion (RRs ranging from 1.01 to 1.21). CONCLUSIONS AND RELEVANCE: Findings from this cohort study suggest that, while COVID-19 vaccination coverage was high among PWH, outreach efforts should focus on those who did not complete vaccine series and those who have uncontrolled viremia. |
MENDS-on-FHIR: leveraging the OMOP common data model and FHIR standards for national chronic disease surveillance
Essaid S , Andre J , Brooks IM , Hohman KH , Hull M , Jackson SL , Kahn MG , Kraus EM , Mandadi N , Martinez AK , Mui JY , Zambarano B , Soares A . JAMIA Open 2024 7 (2) ooae045 OBJECTIVES: The Multi-State EHR-Based Network for Disease Surveillance (MENDS) is a population-based chronic disease surveillance distributed data network that uses institution-specific extraction-transformation-load (ETL) routines. MENDS-on-FHIR examined using Health Language Seven's Fast Healthcare Interoperability Resources (HL7(®) FHIR(®)) and US Core Implementation Guide (US Core IG) compliant resources derived from the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) to create a standards-based ETL pipeline. MATERIALS AND METHODS: The input data source was a research data warehouse containing clinical and administrative data in OMOP CDM Version 5.3 format. OMOP-to-FHIR transformations, using a unique JavaScript Object Notation (JSON)-to-JSON transformation language called Whistle, created FHIR R4 V4.0.1/US Core IG V4.0.0 conformant resources that were stored in a local FHIR server. A REST-based Bulk FHIR $export request extracted FHIR resources to populate a local MENDS database. RESULTS: Eleven OMOP tables were used to create 10 FHIR/US Core compliant resource types. A total of 1.13 trillion resources were extracted and inserted into the MENDS repository. A very low rate of non-compliant resources was observed. DISCUSSION: OMOP-to-FHIR transformation results passed validation with less than a 1% non-compliance rate. These standards-compliant FHIR resources provided standardized data elements required by the MENDS surveillance use case. The Bulk FHIR application programming interface (API) enabled population-level data exchange using interoperable FHIR resources. The OMOP-to-FHIR transformation pipeline creates a FHIR interface for accessing OMOP data. CONCLUSION: MENDS-on-FHIR successfully replaced custom ETL with standards-based interoperable FHIR resources using Bulk FHIR. The OMOP-to-FHIR transformations provide an alternative mechanism for sharing OMOP data. |
The role of stigma and resilience in healthcare engagement among transgender latinas in the U.S. South: Baseline findings from the ChiCAS Study
Goldenberg T , Tanner AE , McGuire T , Alonzo J , Mann-Jackson L , Refugio Aviles L , Galindo CA , Bessler PA , Courtenay-Quirk C , Garcia M , Reboussin BA , Rhodes SD . J Immigr Minor Health 2024 Research demonstrates that stigma and resilience influence transgender peoples' healthcare use. Less is known about transgender Latinas in the U.S. South who face multilevel barriers to healthcare access. We used baseline data from the ChiCAS intervention study. Using logistic regression, we examined how stigma (perceived discrimination related to gender identity, race/ethnicity, sexual behavior and perceived documentation status and internalized transphobia), and resilience (ethnic group pride and social support) are associated with two healthcare outcomes (use of routine medical care and medically supervised gender-affirming hormones). We also explored barriers to accessing both types of care. After removing 13 participants with missing data, our sample size was 131 transgender Latinas in the U.S. South. Most participants (74.8%, n = 98) received routine medical care in the past year and 57.3% (n = 75) had ever received medically supervised gender-affirming hormones. Reports of discrimination were highest for gender identity and documentation status. Race/ethnicity-based discrimination was positively associated with accessing routine medical care in the past year (OR = 1.94, p = 0.048). Having more social support was positively associated with care (routine care: OR = 3.48, p = 0.002 and gender-affirming hormones: OR = 2.33, p = 0.003). The most commonly reported barriers to accessing both types of care included cost, insurance, and not knowing where to go. Findings highlight the importance of social support for healthcare use among transgender Latinas. Social support may be especially important when considering the unique experiences of discrimination faced by transgender Latinas in the U.S. South. |

Griffin I , Berry I , Navarra T , Priyamvada L , Carson WC , Noiman A , Jackson DA , Waltenburg MA , Still W , Lujan L , Beverly J , Willut C , Lee M , Mangla A , Shelus V , Hutson CL , Townsend MB , Satheshkumar PS . Vaccine 2024 We assessed early antibody responses after two doses of JYNNEOS (IMVANEX) mpox vaccine in the District of Columbia (D.C.) in persons at high risk for mpox without characteristic lesions or rash. Participants with PCR mpox negative specimens (oral swab, blood, and/or rectal swab) on the day of receipt of the first vaccine dose and who provided a baseline (day 0) serum sample and at least one serum sample at ∼28, ∼42-56 days, or 180 days post vaccination were included in this analysis. Orthopoxvirus (OPXV)-specific IgG and IgM ELISAs and neutralizing antibody titers were performed, and longitudinal serologic responses were examined. Based on participants' IgG and IgM antibody levels at baseline, they were categorized as naïve or non-naïve. Linear mixed effects regression models were conducted to determine if IgG antibody response over time varied by age, sex, HIV status, and route of administration for both naïve and non-naïve participants. Among both naïve and non-naïve participants IgG seropositivity rates increased until day 42-56, with 89.4 % of naïve and 92.1 % of non-naïve participants having detectable IgG antibodies. The proportion of naive participants with detectable IgG antibodies declined by day 180 (67.7 %) but remained high among non-naïve participants (94.4 %). Neutralizing antibody titers displayed a similar pattern, increasing initially post vaccination but declining by day 180 among naïve participants. There were no significant serologic response differences by age, sex, or HIV status. Serologic response did vary by route of vaccine administration, with those receiving a combination of intradermal and subcutaneous doses displaying significantly higher IgG values than those receiving both doses intradermally. These analyses provide initial insights into the immunogenicity of a two-dose JYNNEOS PEP regimen in individuals at high risk of mpox exposure in the United States. |
Long-term cardiovascular disease outcomes in non-hospitalized medicare beneficiaries diagnosed with COVID-19: Population-based matched cohort study
Yang Q , Chang A , Tong X , Jackson SL , Merritt RK . PLoS One 2024 19 (5) e0302593 BACKGROUND: SARS-CoV2, the virus that causes coronavirus disease 2019 (COVID-19), can affect multiple human organs structurally and functionally, including the cardiovascular system and brain. Many studies focused on the acute effects of COVID-19 on risk of cardiovascular disease (CVD) and stroke especially among hospitalized patients with limited follow-up time. This study examined long-term mortality, hospitalization, CVD and stroke outcomes after non-hospitalized COVID-19 among Medicare fee-for-service (FFS) beneficiaries in the United States. METHODS: This retrospective matched cohort study included 944,371 FFS beneficiaries aged ≥66 years diagnosed with non-hospitalized COVID-19 from April 1, 2020, to April 30, 2021, and followed-up to May 31, 2022, and 944,371 propensity score matched FFS beneficiaries without COVID-19. Primary outcomes were all-cause mortality, hospitalization, and incidence of 15 CVD and stroke. Because most outcomes violated the proportional hazards assumption, we used restricted cubic splines to model non-proportional hazards in Cox models and presented time-varying hazard ratios (HRs) and Bonferroni corrected 95% confidence intervals (CI). RESULTS: The mean age was 75.3 years; 58.0% women and 82.6% non-Hispanic White. The median follow-up was 18.5 months (interquartile range 16.5 to 20.5). COVID-19 showed initial stronger effects on all-cause mortality, hospitalization and 12 incident CVD outcomes with adjusted HRs in 0-3 months ranging from 1.05 (95% CI 1.01-1.09) for mortality to 2.55 (2.26-2.87) for pulmonary embolism. The effects of COVID-19 on outcomes reduced significantly after 3-month follow-up. Risk of mortality, acute myocardial infarction, cardiomyopathy, deep vein thrombosis, and pulmonary embolism returned to baseline after 6-month follow-up. Patterns of initial stronger effects of COVID-19 were largely consistent across age groups, sex, and race/ethnicity. CONCLUSIONS: Our results showed a consistent time-varying effects of COVID-19 on mortality, hospitalization, and incident CVD among non-hospitalized COVID-19 survivors. |
Continuous quality evaluation of the Asanté rapid test for recent infection for robust kit lot quality verification
Zheng A , Detorio M , Dobbs T , Shanmugam V , Tan X , Vuong J , Domaoal RA , Lee K , Williams L , Jackson K , Parekh B , Yufenyuy EL . PLOS Glob Public Health 2024 4 (5) e0003195 The Sedia Biosciences Asanté rapid test for recent infection (RTRI) can identify HIV infections and characterize HIV-1 as recent or long-term infection via the positive verification (V) line and long-term line (LT) line, respectively. Tracking with Recency Assays to Control the Epidemic (TRACE) program uses RTRI assays. Successful implementation of TRACE requires high-quality test performance. The goal of this study is to evaluate the additional quality practices established for new kit lots prior to field use. Asanté lot quality control data from the manufacturer is reviewed by the Centers for Disease Control and Prevention International Laboratory Branch (CDC-ILB) in the Division of Global HIV and TB using. If a lot passes manufacturer quality control and CDC-ILB review, test kits are sent to CDC-ILB for further evaluation. Evaluation by CDC includes inter-rater reliability and linear regressions comparing the V and LT lines against reference data as well as V and LT line data between testers. A Bland-Altman analysis was conducted to assess bias and systematic error. Overall, CDC-ILB passed 29 (91%) out of 32 Sedia Biosciences Asanté kit lots that initially passed manufacturing quality control from July 2017 to May 2020. Regression analyses demonstrate that test kits are performing as expected with consistent R2≥0.92 for both V and LT lines. On average, inter-rater reliability kappa was 0.9, indicating a strong level of agreement. Bland-Altman analyses demonstrate high agreement with little to no systematic error and bias. Ongoing evaluation of new RTRI kit lots is important to ensure high quality test performance. Rejecting 9% of kit lots highlight the importance of continuing to work with manufacturers to ensure consistent kit production and quality assurance (QA) activities. Investing in effective QA measures, conducting both pre- and post-market performance data reviews, could help improve RTRI accuracy and outcomes in similar testing programs. |
Modifications to sexual behaviors associated with Mpox (monkeypox) virus transmission among persons presenting for Mpox vaccination, Washington, D.C., August-October, 2022
Copen CE , Delaney KP , Agnew-Brune C , Berry I , Griffin I , Hassan R , Oakley LP , Wondmeneh S , Rhodes T , Gillani S , Lee M , Ashley P , Willut C , Mangla AT , Waltenburg MA , Jackson DA . Sex Transm Dis 2024 51 (1) 54-60 BACKGROUND: Over 30,000 mpox cases were reported during the 2022 mpox outbreak with many cases occurring among gay, bisexual and other men who have sex with men (MSM). Decreases in U.S. mpox cases were likely accelerated by a combination of vaccination and modifications to sexual behaviors associated with mpox virus transmission. We assessed reports of sexual behavior change among participants receiving mpox vaccination in Washington, DC. METHODS: During August to October 2022, 711 adults aged ≥18 years receiving mpox vaccination at two public health clinics in Washington, DC completed a self-administered questionnaire that asked whether sexual behaviors changed since learning about mpox. We calculated the frequency and percentages of participants reporting an increase, decrease, or no change in 4 of these behaviors by demographic, clinical, and behavioral characteristics with 95% confidence intervals. RESULTS: Overall, between 46% and 61% of participants reported a decrease in sexual behaviors associated with mpox virus transmission, 39% to 54% reported no change in these behaviors, and <1% reported an increase. Approximately 61% reported decreases in one-time sexual encounters (95% confidence interval [CI], 56.8%-64.7%), 54.3% reduced numbers of sex partners (95% CI, 50.4%-58.0%), 53.4% decreased sex via a dating app or sex venue (95% CI, 49.7%-58.0%), and 45.6% reported less group sex (95% CI, 40.4%-50.9%). Reported decreases in these behaviors were higher for MSM than women; in non-Hispanic Black than non-Hispanic White participants; and in participants with human immunodeficiency virus than participants without human immunodeficiency virus. CONCLUSIONS: Most participants receiving mpox vaccination reported decreasing sexual behaviors associated with mpox virus transmission, including groups disproportionately affected by the outbreak. |
Mpox knowledge, attitudes, & practices among persons presenting for JYNNEOS vaccination - District of Columbia, August-October 2022
Hassan R , Wondmeneh S , Gonzalez Jimenez N , Chapman K , Mangla A , Ashley P , Willut C , Lee M , Rhodes T , Gillani S , Copen C , Jackson DA , Waltenburg M , Delaney KP , Miles G , Agnew-Brune C , Oakley LP . Sex Transm Dis 2024 51 (1) 47-53 BACKGROUND: More than 30,000 mpox cases have been confirmed in the United States since May 2022. Mpox cases have disproportionally occurred among adult gay, bisexual, and other men who have sex with men; transgender persons; and Black and Hispanic/Latino persons. We examined knowledge, attitudes, and practices regarding mpox vaccination among adults presenting for vaccination to inform prevention efforts. METHODS: We collected mixed-methods data from a convenience sample of adults presenting for JYNNEOS vaccination at 3 DC Health mpox vaccine clinics during August-October 2022. Survey and interview topics included knowledge about mpox symptoms and vaccine protection, beliefs about vaccine access, and trusted sources of information. RESULTS: In total, 352 participants completed self-administered surveys and 62 participants completed an in-depth interview. Three main themes emerged from survey and interview data. First, most participants had a general understanding about mpox, but gaps remained in comprehensive understanding about mpox symptoms, modes of transmission, vaccine protection, personal risk, and vaccine dosing strategies. Second, participants had high trust in public health agencies. Third, participants wanted more equitable and less stigmatizing access to mpox vaccine services. CONCLUSIONS: Nonstigmatizing, inclusive, and clear communication from trusted sources, including public health agencies, is needed to address mpox knowledge gaps and increase vaccine access and uptake in affected communities. Mpox outreach efforts should continue innovative approaches, including person-level risk assessment tools, to address community needs. |
County-level cardiac rehabilitation and broadband availability: Opportunities for hybrid care in the United States
DeLara DL , Pollack LM , Wall HK , Chang A , Schieb L , Matthews K , Stolp H , Pack QR , Casper M , Jackson SL . J Cardiopulm Rehabil Prev 2024 PURPOSE: Cardiac rehabilitation (CR) improves patient outcomes and quality of life and can be provided virtually through hybrid CR. However, little is known about CR availability in conjunction with broadband access, a requirement for hybrid CR. This study examined the intersection of CR and broadband availability at the county level, nationwide. METHODS: Data were gathered and analyzed in 2022 from the 2019 American Community Survey, the Centers for Medicare & Medicaid Services, and the Federal Communications Commission. Spatially adaptive floating catchments were used to calculate county-level percent CR availability among Medicare fee-for-service beneficiaries. Counties were categorized: by CR availability, whether lowest (ie, CR deserts), medium, or highest; and by broadband availability, whether CR deserts with majority-available broadband, or dual deserts. Results were stratified by state. County-level characteristics were examined for statistical significance by CR availability category. RESULTS: Almost half of US adults (n = 116 325 976, 47.2%) lived in CR desert counties (1691 counties). Among adults in CR desert counties, 96.8% were in CR deserts with majority-available broadband (112 626 906). By state, the percentage of the adult population living in CR desert counties ranged from 3.2% (New Hampshire) to 100% (Hawaii and Washington, DC). Statistically significant differences in county CR availability existed by race/ethnicity, education, and income. CONCLUSIONS: Almost half of US adults live in CR deserts. Given that up to 97% of adults living in CR deserts may have broadband access, implementation of hybrid CR programs that include a telehealth component could expand CR availability to as many as 113 million US adults. |
Hypertension prevalence and control among people with and without HIV - United States, 2022
Weng X , Kompaniyets L , Buchacz K , Thompson-Paul AM , Woodruff RC , Hoover KW , Huang YA , Li J , Jackson SL . Am J Hypertens 2024 BACKGROUND: People with HIV (PWH) have higher rates of cardiovascular disease than people without HIV. However, limited information exists about hypertension prevalence and associated risk factors in PWH. METHODS: This cross-sectional study included adult patients in the 2022 IQVIATM Ambulatory Electronic Medical Record - US data. HIV was identified based on ≥2 HIV diagnosis codes or a positive HIV test. Hypertension was identified by diagnosis codes, ≥2 blood pressure (BP) readings ≥130/80 mmHg, or an antihypertensive medication prescription. Among those with hypertension, control was defined as most recent BP <130/80 mmHg. Logistic models using marginal standardization method were used to estimate adjusted prevalence ratios (aPR) of hypertension and hypertension control among all patients and PWH specifically, controlling for covariates. RESULTS: Of 7,533,379 patients, 19,102 (0.3%) had HIV. PWH had higher hypertension prevalence (66% vs 54%, aPR:1.14, 95% CI: 1.13-1.15) compared with people without HIV. Among persons with hypertension, PWH were more likely to have controlled hypertension (aPR: 1.10, 95% CI: 1.07-1.13) compared with people without HIV. Among PWH, those from the South were more likely to have hypertension (aPR: 1.07, 95% CI: 1.02-1.12) than PWH from the Northeast, while Black PWH were less likely to have controlled hypertension (aPR: 0.72, 95% CI: 0.67-0.77) than White PWH. CONCLUSIONS: PWH were more likely to have hypertension than people without HIV. Geographic and racial disparities in hypertension prevalence and control were observed among PWH. Optimal care for PWH includes comprehensive strategies to screen for, prevent, and manage hypertension. |
