Jackson SL , Woodruff RC , Nagavedu K , Fearrington J , Rolka DB , Twentyman E , Carton TW , Puro J , Denson JL , Kappelman MD , Paranjape A , Thacker D , Weiner MG , Goodman AB , Lekiachvili A , Boehmer TK , Block JP . J Am Heart Assoc 2023 12 (21) e030240 Background Hypertension and diabetes are associated with increased COVID-19 severity. The association between level of control of these conditions and COVID-19 severity is less well understood. Methods and Results This retrospective cohort study identified adults with COVID-19, March 2020 to February 2022, in 43 US health systems in the National Patient-Centered Clinical Research Network. Hypertension control was categorized as blood pressure (BP) <130/80, 130 to 139/80 to 89, 140 to 159/90 to 99, or ≥160/100 mm Hg, and diabetes control as glycated hemoglobin <7%, 7% to <9%, ≥9%. Adjusted, pooled logistic regression assessed associations between hypertension and diabetes control and severe COVID-19 outcomes. Among 1 494 837 adults with COVID-19, 43% had hypertension and 12% had diabetes. Among patients with hypertension, the highest baseline BP was associated with greater odds of hospitalization (adjusted odds ratio [aOR], 1.30 [95% CI, 1.23-1.37] for BP ≥160/100 versus BP <130/80), critical care (aOR, 1.30 [95% CI, 1.21-1.40]), and mechanical ventilation (aOR, 1.32 [95% CI, 1.17-1.50]) but not mortality (aOR, 1.08 [95% CI, 0.98-1.12]). Among patients with diabetes, the highest glycated hemoglobin was associated with greater odds of hospitalization (aOR, 1.61 [95% CI, 1.47-1.76] for glycated hemoglobin ≥9% versus <7%), critical care (aOR, 1.42 [95% CI, 1.31-1.54]), mechanical ventilation (aOR, 1.12 [95% CI, 1.02-1.23]), and mortality (aOR, 1.18 [95% CI, 1.09-1.27]). Black and Hispanic adults were more likely than White adults to experience severe COVID-19 outcomes, independent of comorbidity score and control of hypertension or diabetes. Conclusions Among 1.5 million patients with COVID-19, higher BP and glycated hemoglobin were associated with more severe COVID-19 outcomes. Findings suggest that adults with poorest control of hypertension or diabetes might benefit from efforts to prevent and initiate early treatment of COVID-19. |
The associations of income and Black-White racial segregation with HIV outcomes among adults aged 18 years-United States and Puerto Rico, 2019
Gant Z , Dailey A , Hu X , Song W , Beer L , Johnson Lyons S , Denson DJ , Satcher Johnson A . PLoS One 2023 18 (9) e0291304 OBJECTIVE(S): To examine associations between Index of Concentration at the Extremes (ICE) measures for economic and racial segregation and HIV outcomes in the United States (U.S.) and Puerto Rico. METHODS: County-level HIV testing data from CDC's National HIV Prevention Program Monitoring and Evaluation and census tract-level HIV diagnoses, linkage to HIV medical care, and viral suppression data from the National HIV Surveillance System were used. Three ICE measures of spatial polarization were obtained from the U.S. Census Bureau's American Community Survey: ICEincome (income segregation), ICErace (Black-White racial segregation), and ICEincome+race (Black-White racialized economic segregation). Rate ratios (RRs) for HIV diagnoses and prevalence ratios (PRs) for HIV testing, linkage to care within 1 month of diagnosis, and viral suppression within 6 months of diagnosis were estimated with 95% confidence intervals (CIs) to examine changes across ICE quintiles using the most privileged communities (Quintile 5, Q5) as the reference group. RESULTS: PRs and RRs showed a higher likelihood of testing and adverse HIV outcomes among persons residing in Q1 (least privileged) communities compared with Q5 (most privileged) across ICE measures. For HIV testing percentages and diagnosis rates, across quintiles, PRs and RRs were consistently greatest for ICErace. For linkage to care and viral suppression, PRs were consistently lower for ICEincome+race. CONCLUSIONS: We found that poor HIV outcomes and disparities were associated with income, racial, and economic segregation as measured by ICE. These ICE measures contribute to poor HIV outcomes and disparities by unfairly concentrating certain groups (i.e., Black persons) in highly segregated and deprived communities that experience a lack of access to quality, affordable health care. Expanded efforts are needed to address the social/economic barriers that impede access to HIV care among Black persons. Increased partnerships between government agencies and the private sector are needed to change policies that promote and sustain racial and income segregation. |

Pediatr Res 2023 BACKGROUND: To characterize neurodevelopmental abnormalities in children up to 36 months of age with congenital Zika virus exposure. METHODS: From the U.S. Zika Pregnancy and Infant Registry, a national surveillance system to monitor pregnancies with laboratory evidence of Zika virus infection, pregnancy outcomes and presence of Zika associated birth defects (ZBD) were reported among infants with available information. Neurologic sequelae and developmental delay were reported among children with ≥1 follow-up exam after 14 days of age or with ≥1 visit with development reported, respectively. RESULTS: Among 2248 infants, 10.1% were born preterm, and 10.5% were small-for-gestational age. Overall, 122 (5.4%) had any ZBD; 91.8% of infants had brain abnormalities or microcephaly, 23.0% had eye abnormalities, and 14.8% had both. Of 1881 children ≥1 follow-up exam reported, neurologic sequelae were more common among children with ZBD (44.6%) vs. without ZBD (1.5%). Of children with ≥1 visit with development reported, 46.8% (51/109) of children with ZBD and 7.4% (129/1739) of children without ZBD had confirmed or possible developmental delay. CONCLUSION: Understanding the prevalence of developmental delays and healthcare needs of children with congenital Zika virus exposure can inform health systems and planning to ensure services are available for affected families. IMPACT: We characterize pregnancy and infant outcomes and describe neurodevelopmental abnormalities up to 36 months of age by presence of Zika associated birth defects (ZBD). Neurologic sequelae and developmental delays were common among children with ZBD. Children with ZBD had increased frequency of neurologic sequelae and developmental delay compared to children without ZBD. Longitudinal follow-up of infants with Zika virus exposure in utero is important to characterize neurodevelopmental delay not apparent in early infancy, but logistically challenging in surveillance models. |
Using the Index of Concentration at the Extremes to Evaluate Associations of Income and Black-White Racial Segregation with HIV Outcomes Among Adults Aged >=18 Years - United States and Puerto Rico, 2019 (preprint)
Gant Z , Dailey A , Hu X , Song W , Beer L , Lyons SJ , Denson DJ , Johnson AS . medRxiv 2023 28 Objective(s): To examine associations between Index of Concentration at the Extremes (ICE) measures for economic and racial segregation and HIV outcomes in the United States (U.S.) and Puerto Rico.

Individuals with specimen Ct<30 were more likely to report symptoms but were not different from individuals with high Ct value specimens by other clinical and testing data. |
Changes in spina bifida lesion level after folic acid fortification in the US
Mai CT , Evans J , Alverson CJ , Yue X , Flood T , Arnold K , Nestoridi E , Denson L , Adisa O , Moore CA , Nance A , Zielke K , Rice S , Shan X , Dean JH , Ethen M , Hansen B , Isenburg J , Kirby RS . Obstet Gynecol Surv 2023 78 (4) 189-191 following which a substantial decline in neural tube defects at birth occurred. Studies also have suggested that lesion levels in cases of spina bifida are directly affected by folic acid fortification. Locations of such lesions contribute to outcome and prognosis of the condition. When compared with sacral and lower lumbar lesions, the greatest risks of disability and mortality are associated with cervical, thoracic, and high lumbar lesions. Individuals with thoracic or high lumbar lesions require a wheelchair and orthosis in adulthood for ambulation 70% to 99% of the time. As lesion levels therefore determine function and overall quality of life, assessment of whether folic acid fortification significantly impacts lesion levels is important. This study aimed to examine patterns of lesion levels in spina bifida following mandatory folic acid fortification in the United States. | | A call was issued by the National Birth Defects Prevention Network for State Birth Defects Programs' spina bifida lesion data before and after fortification mandate. To be eligible, programs needed to provide verbatim medical record text descriptions of spina bifida diagnoses. The 6 participating programs were from the states of Arizona, California (covering 8 counties), Oklahoma, South Carolina, Utah, and metropolitan Atlanta (Georgia). Birth years examined included the prefortification years of 1992–1996 and the postfortification period of 1999–2016. Central processing and analysis occurred as each program provided case-level data (deidentified) based on the exclusion/inclusion criteria to the Centers for Disease Control and Prevention. Medical and record text description of the spina bifida diagnosis and codes were the basis of case information, using the International Classification of Diseases, Ninth Edition, Clinical Modification or the Centers for Disease Control and Prevention and Prevention/British Pediatric Association coding system. Types of spina bifida included in the study were spinal rachischisis, myelomeningocele/meningomyelocele, meningocele, and spina bifida not otherwise specified. Cases excluded were cranial lesions, lipomyelomeningocele/lipomeningomyelocele, dysraphism related to split cord malformations, and spina bifida occulta. | | Lesion-level information was provided based on the highest lesion using nonradiographic clinical assessment. Classification of severe upper-level lesions included cervical or thoracic lesion-level cases, whereas lower-level lesions included cases with lumbar or sacral. The study defined open lesion as leaking spinal fluid or membrane covered only, whereas closed lesions were defined as having intact-skin covering and lacking fluid leakage. Spina bifida cases were considered isolated when no other anomalies related to the primary cause of abnormal neural tube closure were present (nor were secondary to the neurologic complications caused by it). Examining associations between fortification period and the outcomes (lesion level and spina bifida) occurred using the generalized estimating approach to logistic (case severity analyses) and log-linear (PR analyses) regression, which accounted for clustering of cases by state. | | From a total of 7,816,062 live births, 2593 cases of spina bifida met the case inclusion criteria. Overall, 573 cases were included in the prefortification period (birth prevalence of 4.07 per 10,000 live births), and 2020 cases were included in the postfortification period (birth prevalence of 3.15 per 10,000 live births). Overall, 80.2% of cases resulted in live births, and most cases of spina bifida involved lower-level lesions (81.3%). Most lesions were lumbar, and the proportions prefortification and postfortification were 61.4% and 72.0%, respectively, with a higher proportion of lumbar lesions seen in the postfortification period. The odds of upper-level to lower-level lesions decreased by 70% after fortification. The spina bifida live birth prevalence decreased significantly and remained consistently low throughout the early, mid, and recent postfortification periods. The study found a 72% decrease overall in prevalence of severe, upper-level lesions following mandatory folic acid fortification in the United States. | | The limitations of the study include the shortcomings of relying on diagnostic codes, the difficulty of coding lesion level using the International Classification of Diseases, Ninth Edition, Clinical Modification coding scheme, the lack of recorded functional outcome for children in medical records (indirect indicators of severity), the lack of preconception and prenatal folic acid data, and the possible variation of case ascertainment within programs contributing studies. A major study strength is its potential to address additional important questions regarding epidemiology and spina bifida. The classification of spinal defects is complex, and this study adds to the limited distribution data that exist for prefortification and postfortification subtypes. | | The study concluded that the overall prevalence of severe upper-level lesions in spina bifida cases experienced a steep reduction following mandatory folic acid fortification institution within the United States, whereas no change in the prevalence of less severe lower-level lesions took place. Additional examinations are warranted to better understand the magnitude and mechanism of spina bifida severity in relation to folic acid intake. |
A cross-sectional analysis of psychosocial and structural barriers and facilitators associated with PrEP use among a sample of transgender women in Chicago, IL
Kuhns LM , Perloff J , Johnson AK , Paul JL , Pleasant K , Evans K , Denson DJ , Gelaude DJ , Bessler PA , Diskin R , Cervantes M , Garofalo R , Hotton AL . AIDS Res Ther 2023 20 (1) 24 BACKGROUND: Expanding pre-exposure prophylaxis (PrEP) among transgender women in the United States is an important strategy to meet national HIV prevention goals, however self-reported use of PrEP is low in this group. METHODS: This study reports the findings of a cross-sectional analysis of the relationship of barriers as well as facilitators to recent PrEP use among transgender women enrolled in an evaluation of the TransLife Care project (Chicago, Illinois), a structural intervention designed to meet basic needs. We computed multivariable prevalence ratios for barriers, facilitators and recent PrEP use, controlling for demographics. RESULTS: Findings suggest that psychosocial and structural barriers, including moderate/high alcohol use, stimulant use, and history of incarceration were all positively associated with recent PrEP use among urban transgender women. In addition, a psychosocial facilitator, gender affirmation, was positively associated with recent PrEP use, while, while collective self-esteem, a was negatively associated with it. Finally, common indications for PrEP have high sensitivity, but low specificity and predictive value for identifying those on PrEP. CONCLUSION: We conclude that despite a large gap in PrEP use among those with indications, individuals experiencing psychosocial and structural barriers are more likely to use PrEP, and facilitators, such as psychological sense of affirmed gender may support its use.

Jackson SL , Block JP , Rolka DB , Pavkov ME , Chevinsky JR , Lekiachvili A , Carton TW , Thacker D , Denson JL , Paranjape A , Kappelman MD , Boehmer TK , Twentyman E . AJPM Focus 2022 1 (1) 100012 INTRODUCTION: Hypertension and diabetes are associated with increased COVID-19 severity, yet less is known about COVID-19 outcomes across levels of disease control for these conditions. METHODS: All adults aged 20 years with COVID-19 between March 1, 2020 and March 15, 2021 in 42 healthcare systems in National Patient-Centered Clinical Research Network were identified. RESULTS: Among 656,049 adults with COVID-19, 41% had hypertension, and 13% had diabetes. Of patients with classifiable hypertension, 35% had blood pressure <130/80 mmHg, 40% had blood pressure of 130139/8089 mmHg, 21% had blood pressure of 140159/9099 mmHg, and 6% had blood pressure 160/100 mmHg. Severe COVID-19 outcomes were more prevalent among those with blood pressure of 160/100 than among those with blood pressure of 130-139/80-89, including hospitalization (23.7% [95% CI=23.0, 24.4] vs 11.7% [95% CI=11.5, 11.9]), receipt of critical care (5.5% [95% CI=5.0, 5.8] vs 2.4% [95% CI=2.3, 2.5]), receipt of mechanical ventilation (3.0% [95% CI=2.7, 3.3] vs 1.2% [95% CI=1.1, 1.3]), and 60-day mortality (4.6% [95% CI=4.2, 4.9] vs 1.8% [95% CI=1.7, 1.9]). Of patients with classifiable diabetes, 44% had HbA1c <7%, 35% had HbA1c 7% to <9%, and 21% had HbA1c 9%. Hospitalization prevalence was 31.3% (95% CI=30.7, 31.9) among those with HbA1c <7% vs 40.2% (95% CI=39.4, 41.1) among those with HbA1c 9%; other outcomes did not differ substantially by HbA1c. CONCLUSIONS: These findings highlight the importance of appropriate management of hypertension and diabetes, including during public health emergencies such as the COVID-19 pandemic. |
A health equity approach for implementation of JYNNEOS vaccination at large, community-based LGBTQIA+ events - Georgia, August 27-September 5, 2022
Millman AJ , Denson DJ , Allen ML , Malone JA , Daskalakis DC , Durrence D , Rustin RC , Toomey KE . MMWR Morb Mortal Wkly Rep 2022 71 (43) 1382-1883 Gay, bisexual, and other men who have sex with men (MSM) have been disproportionately affected during the 2022 U.S. monkeypox outbreak, with Black or African American (Black) MSM being the most affected demographic group (1). As of September 28, 2022, Georgia had reported 1,784 monkeypox cases; 98% of which occurred in males and 77% among Black persons (2). As of September 13, 2022, 60% of reported cases were among persons with HIV infection, and 50% of persons with monkeypox had a sexually transmitted infection within the past year (3). Because of racial disparities in the incidence of monkeypox cases and a large proportion of cases among MSM in Georgia, early vaccination beginning in July focused on improving equitable access by establishing new and leveraging existing partnerships with community-based organizations that serve affected populations, including persons with HIV infection. Despite these efforts, disparities persisted because of high demand and limited vaccine supply. The Georgia Department of Public Health (DPH) requested CDC support for a vaccine pilot and received an additional allocation of 5,500 doses of JYNNEOS vaccine for administration at events leading up to and throughout a Black gay Pride festival in Atlanta, a multiday event held Labor Day weekend (September 2-5, 2022). The event celebrates lesbian, gay, bisexual, transgender, queer or questioning, intersex, asexual, and other (LGBTQIA+) communities of color and hosts more than 125,000 attendees each year. Before the festival (as of August 24), 17,546 persons had been vaccinated in Georgia, of whom 96% were male, 34% aged 25-36 years, 44% Black, and 8% Hispanic or Latino (Hispanic) (4). |
Racial and Ethnic Disparities in Outpatient Treatment of COVID-19 - United States, January-July 2022.
Boehmer TK , Koumans EH , Skillen EL , Kappelman MD , Carton TW , Patel A , August EM , Bernstein R , Denson JL , Draper C , Gundlapalli AV , Paranjape A , Puro J , Rao P , Siegel DA , Trick WE , Walker CL , Block JP . MMWR Morb Mortal Wkly Rep 2022 71 (43) 1359-1365 In December 2021 and early 2022, four medications received emergency use authorization (EUA) by the Food and Drug Administration for outpatient treatment of mild-to-moderate COVID-19 in patients who are at high risk for progressing to severe disease; these included nirmatrelvir/ritonavir (Paxlovid) and molnupiravir (Lagevrio) (both oral antivirals), expanded use of remdesivir (Veklury; an intraveneous antiviral), and bebtelovimab (a monoclonal antibody [mAb]).* Reports have documented disparities in mAb treatment by race and ethnicity (1) and in oral antiviral treatment by zip code-level social vulnerability (2); however, limited data are available on racial and ethnic disparities in oral antiviral treatment.(†) Using electronic health record (EHR) data from 692,570 COVID-19 patients aged ≥20 years who sought medical care during January-July 2022, treatment with Paxlovid, Lagevrio, Veklury, and mAbs was assessed by race and ethnicity, overall and among high-risk patient groups. During 2022, the percentage of COVID-19 patients seeking medical care who were treated with Paxlovid increased from 0.6% in January to 20.2% in April and 34.3% in July; the other three medications were used less frequently (0.7%-5.0% in July). During April-July 2022, when Paxlovid use was highest, compared with White patients, Black or African American (Black) patients were prescribed Paxlovid 35.8% less often, multiple or other race patients 24.9% less often, American Indian or Alaska Native and Native Hawaiian or other Pacific Islander (AIAN/NHOPI) patients 23.1% less often, and Asian patients 19.4% less often; Hispanic patients were prescribed Paxlovid 29.9% less often than non-Hispanic patients. Racial and ethnic disparities in Paxlovid treatment were generally somewhat higher among patients at high risk for severe COVID-19, including those aged ≥50 years and those who were immunocompromised. The expansion of programs focused on equitable awareness of and access to outpatient COVID-19 treatments, as well as COVID-19 vaccination, including updated bivalent booster doses, can help protect persons most at risk for severe illness and facilitate equitable health outcomes. |
Clusters of rapid HIV transmission among gay, bisexual, and other men who have sex with men - United States, 2018-2021
Perez SM , Panneer N , France AM , Carnes N , Curran KG , Denson DJ , Oster AM . MMWR Morb Mortal Wkly Rep 2022 71 (38) 1201-1206 Gay, bisexual, and other men who have sex with men (MSM) accounted for 68% of new HIV diagnoses in the United States in 2020* (1). Despite advances in treatment and prevention, HIV transmission among MSM continues, in part because of stigma and barriers to accessing prevention and treatment services (2). HIV cluster detection and response, a core strategy of the Ending the HIV Epidemic in the United States initiative,() is an important tool for early identification and response to rapid HIV transmission, including among MSM. To better understand rapid HIV transmission among this population, CDC characterized large HIV molecular clusters detected using analysis of HIV-1 nucleotide sequence data from the National HIV Surveillance System (NHSS).() Among 38 such clusters first detected during 2018-2019 that had grown to include more than 25 persons by December 2021, 29 occurred primarily among MSM. Clusters primarily among MSM occurred in all geographic regions, and 97% involved multiple states. Clusters were heterogeneous in age, gender identity, and race and ethnicity and had rapid growth rates (median=nine persons added per year). The overall transmission rate at cluster detection was 22 transmission events per 100 person-years, more than six times that of previously estimated national transmission rates (3). Most clusters of rapid HIV transmission occur among MSM. Swift response to reach diverse persons and communities with early, tailored, and focused interventions is essential to reducing HIV transmission (4). |

Birth Defects Res 2022 114 (14) 805-811 During the Centers for Disease Control and Prevention's Zika Virus Response, birth defects surveillance programs adapted to monitor birth defects potentially related to Zika virus (ZIKV) infection during pregnancy. Pregnancy outcomes occurring during January 2016 to June 2017 in 22 U.S. states and territories were used to estimate the prevalence of those brain and eye defects potentially related to ZIKV. Jurisdictions were divided into three groups: areas with widespread ZIKV transmission, areas with limited local ZIKV transmission, and areas without local ZIKV transmission. Prevalence estimates for selected brain and eye defects and microcephaly per 10,000 live births were estimated. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated using Poisson regression for areas with widespread and limited ZIKV transmission compared with areas without local ZIKV transmission. Defects with significantly higher prevalence in areas of widespread transmission were pooled, and PRs were calculated by quarter, comparing subsequent quarters to the first quarter (January-March 2016). Nine defects had significantly higher prevalence in areas of widespread transmission. The highest PRs were seen in intracranial calcifications (PR = 12.6, 95% CI [7.4, 21.3]), chorioretinal abnormalities (12.5 [7.1, 22.3]), brainstem abnormalities (9.3 [4.7, 18.4]), and cerebral/cortical atrophy (6.7 [4.2, 10.8]). The PR of the nine pooled defects was significantly higher in three quarters in areas with widespread transmission. The largest difference in prevalence was observed for defects consistently reported in infants with congenital ZIKV infection. Birth defects surveillance programs could consider monitoring a subset of birth defects potentially related to ZIKV in pregnancy. |
"We in this fight together": HIV treatment and prevention among couples of HIV-discordant Black and Latino men who have sex with men
Denson DJ , Gelaude D , Schoua-Glusberg A . J Prev Health Promot 2022 1 HIV-positive Black and Latino men who have sex with men (MSM) have substantial challenges accessing and engaging in HIV care. Findings presented here are an analysis of 14 HIV-discordant couples (N = 28) from Atlanta, GA; Baltimore, MD; Chicago, IL; Los Angeles, CA; and Washington, DC. One-hour in-depth interviews were conducted. Interviews were analyzed using a qualitative content analysis approach. Most couples reported relationship fears associated with delayed disclosure, HIV care engagement instigated by the HIV-uninfected partner, and varying knowledge and concern about the impacts of HIV infection and risk reduction. Findings suggest an opportunity to jointly educate and treat MSM of color in HIV-discordant relationships to improve engagement in ART and PrEP care and adherence. |
Implementing the COVID-19 Rapid Community Assessment on Vaccine Confidence: Lessons Learned from Alabama and Georgia.
Kobau R , Carry M , Rubenstein BL , Denson D , Uribe C , Zajac J , Kidder DP , Peacock G , Abad N . Public Health Rep 2022 137 (5) 333549221112610 Engaging communities is a key strategy to increase COVID-19 vaccination. The Centers for Disease Control and Prevention (CDC) COVID-19 Vaccine Confidence Rapid Community Assessment Guide was developed for community partners to obtain insights about barriers to COVID-19 vaccine uptake and to engage community partners in designing interventions to build vaccine confidence. In spring 2021, 3 CDC teams were deployed to Alabama and Georgia to conduct a rapid community assessment in selected jurisdictions. Data collection included interviews, listening sessions, observations, and street intercept surveys. We identified 3 facilitators and barriers to vaccine uptake: (1) planning and coordination, (2) capacity and implementation, and (3) attitudes and beliefs. We found that the use of the rapid community assessment in Alabama and Georgia was feasible to implement, useful in eliciting unique community concerns and dispelling assumptions, and useful in informing intervention strategies. Our results underscore the importance of community engagement in COVID-19 mitigation strategies. |

J Pediatr 2022 249 59-66 e1 OBJECTIVE: To assess whether the severity of cases of spina bifida changed after mandatory folic acid fortification in the United States. STUDY DESIGN: Six active population-based birth defects programs provided data on cases of spina bifida for 1992-1996 (pre-fortification) and 1999-2016 (post-fortification); programs contributed varying years of data. Case information included both medical record verbatim text description of the spina bifida diagnosis and spina bifida codes (International Classification of Diseases, Clinical Modification, or a modified birth defects surveillance coding system). Comparing pre- with post-fortification periods, adjusted odds ratios (aOR) for case severity [upper-level (cervical, thoracic) to lower-level (lumbar, sacral) lesion cases] and prevalence ratios (PR) were estimated. RESULTS: A total of 2,593 cases of spina bifida (7,816,062 live births) met inclusion criteria, with 573 and 2,020 cases from the pre- and post-fortification periods respectively. Case severity decreased 70% (aOR: 0.30; 95% confidence interval [CI] 0.26, 0.35) between the fortification periods. The decrease was most pronounced for non-Hispanic white mothers. Overall spina bifida prevalence declined 23% (PR=0.77, 95% CI=0.71, 0.85), with similar reduction seen across early, mid, and recent post-fortification periods. A statistically significant decrease in upper-level lesions occurred in the post-fortification compared with pre-fortification periods (PR=0.28, 95% CI=0.22, 0.34), while prevalence of lower-level lesions remained relatively similar (PR: 0.94, 95% CI: 0.84, 1.05). CONCLUSIONS: Severity of cases of spina bifida decreased after mandatory folic acid fortification in the United States. Further examination is warranted to understand better the potential effect of folic acid on spina bifida severity. |
Racial and Ethnic Disparities in Receipt of Medications for Treatment of COVID-19 - United States, March 2020-August 2021.
Wiltz JL , Feehan AK , Molinari NM , Ladva CN , Truman BI , Hall J , Block JP , Rasmussen SA , Denson JL , Trick WE , Weiner MG , Koumans E , Gundlapalli A , Carton TW , Boehmer TK . MMWR Morb Mortal Wkly Rep 2022 71 (3) 96-102 The COVID-19 pandemic has magnified longstanding health care and social inequities, resulting in disproportionately high COVID-19-associated illness and death among members of racial and ethnic minority groups (1). Equitable use of effective medications (2) could reduce disparities in these severe outcomes (3). Monoclonal antibody (mAb) therapies against SARS-CoV-2, the virus that causes COVID-19, initially received Emergency Use Authorization (EUA) from the Food and Drug Administration (FDA) in November 2020. mAbs are typically administered in an outpatient setting via intravenous infusion or subcutaneous injection and can prevent progression of COVID-19 if given after a positive SARS-CoV-2 test result or for postexposure prophylaxis in patients at high risk for severe illness.(†) Dexamethasone, a commonly used steroid, and remdesivir, an antiviral drug that received EUA from FDA in May 2020, are used in inpatient settings and help prevent COVID-19 progression(§) (2). No large-scale studies have yet examined the use of mAb by race and ethnicity. Using COVID-19 patient electronic health record data from 41 U.S. health care systems that participated in the PCORnet, the National Patient-Centered Clinical Research Network,(¶) this study assessed receipt of medications for COVID-19 treatment by race (White, Black, Asian, and Other races [including American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, and multiple or Other races]) and ethnicity (Hispanic or non-Hispanic). Relative disparities in mAb** treatment among all patients(††) (805,276) with a positive SARS-CoV-2 test result and in dexamethasone and remdesivir treatment among inpatients(§§) (120,204) with a positive SARS-CoV-2 test result were calculated. Among all patients with positive SARS-CoV-2 test results, the overall use of mAb was infrequent, with mean monthly use at 4% or less for all racial and ethnic groups. Hispanic patients received mAb 58% less often than did non-Hispanic patients, and Black, Asian, or Other race patients received mAb 22%, 48%, and 47% less often, respectively, than did White patients during November 2020-August 2021. Among inpatients, disparities were different and of lesser magnitude: Hispanic inpatients received dexamethasone 6% less often than did non-Hispanic inpatients, and Black inpatients received remdesivir 9% more often than did White inpatients. Vaccines and preventive measures are the best defense against infection; use of COVID-19 medications postexposure or postinfection can reduce morbidity and mortality and relieve strain on hospitals but are not a substitute for COVID-19 vaccination. Public health policies and programs centered around the specific needs of communities can promote health equity (4). Equitable receipt of outpatient treatments, such as mAb and antiviral medications, and implementation of prevention practices are essential to reducing existing racial and ethnic inequities in severe COVID-19-associated illness and death. |

MMWR Morb Mortal Wkly Rep 2022 71 (3) 73-79 Zika virus infection during pregnancy can cause serious birth defects of the brain and eyes, including intracranial calcifications, cerebral or cortical atrophy, chorioretinal abnormalities, and optic nerve abnormalities (1,2). The frequency of these Zika-associated brain and eye defects, based on data from the U.S. Zika Pregnancy and Infant Registry (USZPIR), has been previously reported in aggregate (3,4). This report describes the frequency of individual Zika-associated brain and eye defects among infants from pregnancies with laboratory evidence of confirmed or possible Zika virus infection. Among 6,799 live-born infants in USZPIR born during December 1, 2015-March 31, 2018, 4.6% had any Zika-associated birth defect; in a subgroup of pregnancies with a positive nucleic acid amplification test (NAAT) for Zika virus infection, the percentage was 6.1% of live-born infants. The brain and eye defects most frequently reported included microcephaly, corpus callosum abnormalities, intracranial calcification, abnormal cortical gyral patterns, ventriculomegaly, cerebral or cortical atrophy, chorioretinal abnormalities, and optic nerve abnormalities. Among infants with any Zika-associated birth defect, one third had more than one defect reported. Certain brain and eye defects in an infant might prompt suspicion of prenatal Zika virus infection. These findings can help target surveillance efforts to the most common brain and eye defects associated with Zika virus infection during pregnancy should a Zika virus outbreak reemerge, and might provide a signal to the reemergence of Zika virus, particularly in geographic regions without ongoing comprehensive Zika virus surveillance. |
"Why You Putting This Drug in Your Body to Fight off Something that You Don't Have" Perceptions about PrEP Use among Black and Latino Men Who Have Sex with Men in the U.S. South
Gelaude D , Denson D . J Homosex 2021 70 (5) 1-17 PrEP use has steadily increased since its introduction, yet uptake remains slow among MSM of color in the U.S. South. Findings presented are from a qualitative study conducted in 2016 exploring factors related to remaining HIV negative among Black (n = 99) and Latino (n = 51) MSM in Atlanta, Baton Rouge, New Orleans, Jackson, and Miami. One-hour in-depth interviews were analyzed using a qualitative content analysis approach. MSM perceived PrEP as providing relief from fear and as an insurance policy against HIV infection but were likely to consider themselves at low risk for HIV. Identified factors influencing PrEP use included side effects, medical mistrust, and stigma. Cost and access were not seen as major barriers. Findings suggest MSM of color in the South may view PrEP as too risky for their HIV prevention needs. PrEP providers can address medical mistrust, discuss side effects, and emphasize positive aspects of PrEP use to increase uptake. (150 words). |
Pulmonary delivery of the broad-spectrum matrix metalloproteinase inhibitor marimastat diminishes multiwalled carbon nanotube-induced circulating bioactivity without reducing pulmonary inflammation
Young TL , Mostovenko E , Denson JL , Begay JG , Lucas SN , Herbert G , Zychowski K , Hunter R , Salazar R , Wang T , Fraser K , Erdely A , Ottens AK , Campen MJ . Part Fibre Toxicol 2021 18 (1) 34 BACKGROUND: Multiwalled carbon nanotubes (MWCNT) are an increasingly utilized engineered nanomaterial that pose the potential for significant risk of exposure-related health outcomes. The mechanism(s) underlying MWCNT-induced toxicity to extrapulmonary sites are still being defined. MWCNT-induced serum-borne bioactivity appears to dysregulate systemic endothelial cell function. The serum compositional changes after MWCNT exposure have been identified as a surge of fragmented endogenous peptides, likely derived from matrix metalloproteinase (MMP) activity. In the present study, we utilize a broad-spectrum MMP inhibitor, Marimastat, along with a previously described oropharyngeal aspiration model of MWCNT administration to investigate the role of MMPs in MWCNT-derived serum peptide generation and endothelial bioactivity. RESULTS: C57BL/6 mice were treated with Marimastat or vehicle by oropharyngeal aspiration 1 h prior to MWCNT treatment. Pulmonary neutrophil infiltration and total bronchoalveolar lavage fluid protein increased independent of MMP blockade. The lung cytokine profile similarly increased following MWCNT exposure for major inflammatory markers (IL-1β, IL-6, and TNF-α), with minimal impact from MMP inhibition. However, serum peptidomic analysis revealed differential peptide compositional profiles, with MMP blockade abrogating MWCNT-derived serum peptide fragments. The serum, in turn, exhibited differential potency in terms of inflammatory bioactivity when incubated with primary murine cerebrovascular endothelial cells. Serum from MWCNT-treated mice led to inflammatory responses in endothelial cells that were significantly blunted with serum from Marimastat-treated mice. CONCLUSIONS: Thus, MWCNT exposure induced pulmonary inflammation that was largely independent of MMP activity but generated circulating bioactive peptides through predominantly MMP-dependent pathways. This MWCNT-induced lung-derived bioactivity caused pathological consequences of endothelial inflammation and barrier disruption. |
Evaluating Locally Developed Interventions to Promote PrEP Among Racially/Ethnically Diverse Transgender Women in the United States: A Unique CDC Initiative.

AIDS Educ Prev 2021 33 (4) 345-360 In the United States, transgender women are disproportionately affected by HIV. However, few evidence-based prevention interventions exist for this key population. We describe two promising, locally developed interventions that are currently being implemented and evaluated through the Centers for Disease Control and Prevention Combination HIV Prevention for Transgender Women Project: (a) ChiCAS, designed to promote the uptake of pre-exposure prophylaxis (PrEP), condom use, and medically supervised hormone therapy among Spanish-speaking transgender Latinas, and (b) TransLife Care, designed to address the structural drivers of HIV risk through access to housing, employment, legal services, and medical services, including HIV preventive care (e.g., PrEP use) among racially/ethnically diverse urban transgender women. If the evaluation trials determine that these interventions are effective, they will be among the first such interventions for use with transgender women incorporating PrEP, thereby contributing to the evidence-based resources that may be used to reduce HIV risk among this population. |
Improving HIV medical care engagement by attending to status disclosure and social support
Carnes NA , Carey JW , Gelaude DJ , Denson DJ , Bessler PA . AIDS Care 2020 33 (1) 1-7 Expeditious linkage and consistent engagement in medical care is important for people with HIV's (PWH) health. One theory on fostering linkage and engagement involves HIV status disclosure to mobilize social support. To assess disclosure and social support's association with linkage and engagement, we conducted a qualitative study sampling black and Latino men who have sex with men (MSM of color) in the U.S. Participants' narratives presented mixed results. For instance, several participants who reported delaying, inconsistent access, or detachment from care also reported disclosing for support purposes, yet sporadic engagement suggests that their disclosure or any subsequent social support have not assisted. The findings contribute to the literature that questions disclosure and social support's influence on care engagement, especially when decontextualized from circumstances and intentions. Our findings suggest the mechanics of disclosure and social support require planned implementation if intending to affect outcomes, especially among MSM of color. From the findings, we explore steps that may bolster interventions seeking to anchor medical care engagement. |

MMWR Morb Mortal Wkly Rep 2020 69 (3) 67-71 Zika virus infection during pregnancy can cause congenital brain and eye abnormalities and is associated with neurodevelopmental abnormalities (1-3). In areas of the United States that experienced local Zika virus transmission, the prevalence of birth defects potentially related to Zika virus infection during pregnancy increased in the second half of 2016 compared with the first half (4). To update the previous report, CDC analyzed population-based surveillance data from 22 states and territories to estimate the prevalence of birth defects potentially related to Zika virus infection, regardless of laboratory evidence of or exposure to Zika virus, among pregnancies completed during January 1, 2016-June 30, 2017. Jurisdictions were categorized as those 1) with widespread local transmission of Zika virus; 2) with limited local transmission of Zika virus; and 3) without local transmission of Zika virus. Among 2,004,630 live births, 3,359 infants and fetuses with birth defects potentially related to Zika virus infection during pregnancy were identified (1.7 per 1,000 live births, 95% confidence interval [CI] = 1.6-1.7). In areas with widespread local Zika virus transmission, the prevalence of birth defects potentially related to Zika virus infection during pregnancy was significantly higher during the quarters comprising July 2016-March 2017 (July-September 2016 = 3.0; October-December 2016 = 4.0; and January-March 2017 = 5.6 per 1,000 live births) compared with the reference period (January-March 2016) (1.3 per 1,000). These findings suggest a fourfold increase (prevalence ratio [PR] = 4.1, 95% CI = 2.1-8.4) in birth defects potentially related to Zika virus in widespread local transmission areas during January-March 2017 compared with that during January-March 2016, with the highest prevalence (7.0 per 1,000 live births) in February 2017. Population-based birth defects surveillance is critical for identifying infants and fetuses with birth defects potentially related to Zika virus regardless of whether Zika virus testing was conducted, especially given the high prevalence of asymptomatic disease. These data can be used to inform follow-up care and services as well as strengthen surveillance. |
"To me, everybody is infected": Understanding narratives about HIV risk among HIV-negative black men who have sex with men in the Deep South
Denson DJ , Gelaude D , Saul H , Schoua-Glusberg A , Randall LA , Kenward K , Gall E , Hickson D , Schamel J , Frew PM . J Homosex 2019 68 (6) 1-20 For black MSM living in the Deep South, the intersection of sexuality, race, and geography impacts HIV risk substantially. Between July and September 2016, we conducted a qualitative study among HIV-negative black MSM in five southern cities in the US with elevated HIV prevalence. Analysis included assessment of interrater reliability, cluster analysis, and descriptive statistics. We enrolled 99 black MSM (mean age: 33.6; SD = 12.8; range: 17-68 years). Four overarching themes emerged: harboring fear of HIV and the internalization of HIV stigma; scrutinizing potential partners to assess riskiness and HIV status; embracing distance and isolation from those perceived as a threat to HIV status; and exhibiting self-efficacy toward HIV prevention and utilizing risk reduction strategies. Future HIV prevention efforts may benefit by balancing risk and deficit based strategies with those that emphasize resilience, address disenfranchisement via structural interventions, and assess and treat inherent trauma(s). |
Barriers and facilitators for antiretroviral treatment adherence among HIV-positive African American and Latino men who have sex with men
Carey JW , Carnes N , Schoua-Glusberg A , Kenward K , Gelaude D , Denson DJ , Gall E , Randall LA , Frew PM . AIDS Educ Prev 2019 31 (4) 306-324 Some Black/African American and Hispanic/Latino men who have sex with men (MSM) living with HIV do not take antiretroviral therapy (ART). We conducted semistructured interviews with 84 adult, Black/African American and Hispanic/Latino MSM with HIV to understand ART barriers and facilitators. We used chi-square statistics to identify factors associated with ART use (p </= .05), and selected illustrative quotes. Over half (51.2%) said they followed their doctor's instructions; however, only 27.4% reported consistently taking ART. Some men delayed ART until overcoming diagnosis denial or becoming very sick. ART use was facilitated by encouragement from others, treatment plans, side effect management, lab test improvements, pill-taking reminders, and convenient care facilities that provide "one-stop shop" services. Men were more likely to take ART when having providers who communicated effectively and were perceived to treat them with respect. Healthcare personnel can use our findings to strengthen services for MSM of color. |
Changes in HIV preexposure prophylaxis awareness and use among men who have sex with men - 20 urban areas, 2014 and 2017
Finlayson T , Cha S , Xia M , Trujillo L , Denson D , Prejean J , Kanny D , Wejnert C . MMWR Morb Mortal Wkly Rep 2019 68 (27) 597-603 In February 2019, the U.S. Department of Health and Human Services proposed a strategic initiative to end the human immunodeficiency (HIV) epidemic in the United States by reducing new HIV infections by 90% during 2020-2030* (1). Phase 1 of the Ending the HIV Epidemic initiative focuses on Washington, DC; San Juan, Puerto Rico; and 48 counties where the majority of new diagnoses of HIV infection in 2016 and 2017 were concentrated and on seven states with a disproportionate occurrence of HIV in rural areas relative to other states.(dagger) One of the four pillars in the initiative is protecting persons at risk for HIV infection using proven, comprehensive prevention approaches and treatments, such as HIV preexposure prophylaxis (PrEP), which is the use of antiretroviral medications that have proven effective at preventing infection among persons at risk for acquiring HIV. In 2014, CDC released clinical PrEP guidelines to health care providers (2) and intensified efforts to raise awareness and increase the use of PrEP among persons at risk for infection, including gay, bisexual, and other men who have sex with men (MSM), a group that accounted for an estimated 68% of new HIV infections in 2016 (3). Data from CDC's National HIV Behavioral Surveillance (NHBS) were collected in 20 U.S. urban areas in 2014 and 2017, covering 26 of the geographic areas included in Phase I of the Ending the HIV Epidemic initiative, and were compared to assess changes in PrEP awareness and use among MSM. From 2014 to 2017, PrEP awareness increased by 50% overall, with >80% of MSM in 17 of the 20 urban areas reporting PrEP awareness in 2017. Among MSM with likely indications for PrEP (e.g., sexual risk behaviors or recent bacterial sexually transmitted infection [STI]), use of PrEP increased by approximately 500% from 6% to 35%, with significant increases observed in all urban areas and in almost all demographic subgroups. Despite this progress, PrEP use among MSM, especially among black and Hispanic MSM, remains low. Continued efforts to improve coverage are needed to reach the goal of 90% reduction in HIV incidence by 2030. In addition to developing new ways of connecting black and Hispanic MSM to health care providers through demonstration projects, CDC has developed resources and tools such as the Prescribe HIV Prevention program to enable health care providers to integrate PrEP into their clinical care.( section sign) By routinely testing their patients for HIV, assessing HIV-negative patients for risk behaviors, and prescribing PrEP as needed, health care providers can play a critical role in this effort. |
PrEP awareness in the context of HIV/AIDS conspiracy beliefs among black/African American and Hispanic/Latino MSM in three urban US cities
Olansky E , Mansergh G , Pitts N , Mimiaga MJ , Denson DJ , Landers S , Holman J , Herbst JH . J Homosex 2019 67 (6) 1-11 We examined HIV conspiracy beliefs and PrEP awareness in a convenience sample of minority MSM. Participants in three cities completed a behavioral self-assessment on sociodemographics, PrEP awareness, and HIV/AIDS conspiracy beliefs. HIV/AIDS conspiracy beliefs were more common among Black than Latino MSM (58% vs. 42%, p < .05), and among younger men than older men (age 18-29 (50%), 30-39 (22%), 40+ (28%); p < .05). PrEP awareness co-occurred with conspiracy belief less (37%) than with non-belief (63%, p < .05), persisting in multivariable regression (aOR = 0.52, 95% CI = 0.38-0.71). This relationship suggests that current HIV care and prevention messaging is either inaccessible or not credible to some minority subpopulations. |
Population-based birth defects data in the United States, 2011-2015: A focus on eye and ear defects

Birth Defects Res 2018 110 (19) 1478-1486 BACKGROUND/OBJECTIVES: In this data brief, we examine major eye and ear anomalies (anophthalmia/microphthalmia, anotia/microtia, and congenital cataract) for a recent 5-year birth cohort using data from 30 population-based birth defects surveillance programs in the United States. METHODS: As a special call for data for the 2018 NBDPN Annual Report, state programs reported expanded data on eye/ear anomalies for birth years 2011-2015. We calculated the combined overall prevalence (per 10,000 live births) and 95% confidence intervals (CI), for the three anomalies as well as by maternal age, maternal race/ethnicity, infant sex, laterality, presence/absence of other major birth defects, and case ascertainment methodology utilized by the program (active vs. passive). RESULTS: The overall prevalence estimate (per 10,000 live births) was 1.5 (95% CI: 1.4-1.5) for anophthalmia/microphthalmia, 1.5 (95% CI: 1.4-1.6) for congenital cataract, and 1.8 (95% CI: 1.7-1.8) for anotia/microtia. Congenital cataract prevalence varied little by maternal race/ethnicity, infant sex, or case ascertainment methodology; prevalence differences were more apparent across strata for anophthalmia/microphthalmia and anotia/microtia. Prevalence among active vs. passive ascertainment programs was 50% higher for anophthalmia/microphthalmia (1.9 vs. 1.2) and two-fold higher for anotia/microtia (2.6 vs. 1.2). Anophthalmia/microphthalmia was more likely than other conditions to co-occur with other birth defects. All conditions were more frequent among older mothers (40+ years). CONCLUSIONS: This data brief provides recent prevalence estimates for anophthalmia/microphthalmia, congenital cataract, and anotia/microtia that address a data gap by examining pooled data from 30 population-based surveillance systems, covering a five-year birth cohort of about 12.4 million births. |
Barriers and facilitators for clinical care engagement among HIV-positive African American and Latino men who have sex with men
Carey JW , Carnes N , Schoua-Glusberg A , Kenward K , Gelaude D , Denson D , Gall E , Randall LA , Frew PM . AIDS Patient Care STDS 2018 32 (5) 191-201 Achieving optimal health among people living with HIV (PLWH) requires linkage to clinical care upon diagnosis, followed by ongoing engagement in HIV clinical care. A disproportionate number of black/African American and Hispanic/Latino men who have sex with men (MSM) living with HIV do not, however, achieve ongoing care. We conducted semistructured interviews in 2014 with 84 urban black/African American and Hispanic/Latino MSM living with HIV to understand their barriers and facilitators to engagement. We classified men as care-engaged or not at the time of the interview, and conducted content analysis of the interview transcripts to identify barriers and facilitators to engagement. Respondent mean age was 42.4 years (range, 20-59). Over half (59.5%, n = 50) were black/African American. Slightly more than a third (38.1%, n = 32) reported not being continuously care-engaged since diagnosis, and 17.9% (n = 15) delayed entry, although they have subsequently entered and remained in care. Sustained engagement began with overcoming denial after diagnosis and having treatment plans, as well as having conveniently located care facilities. Engagement also was facilitated by services tailored to meet multiple patient needs, effective patient-provider communication, and providers who show empathy and respect for their patients. Respondents were less likely to be care-engaged when these factors were absent. It can be difficult for racial and ethnic minority MSM living with HIV to begin and sustain care engagement. To optimize care engagement, our findings underscore the value of (1) convenient multipurpose HIV care facilities that meet patient needs; (2) excellent provider-patient communication that reinforces respect, trust, and HIV treatment literacy; and (3) assisting PLWH to create personalized treatment plans and overcome possible challenges such as diagnosis denial. |
A rapid review of eHealth interventions addressing the continuum of HIV care (2007-2017)
Henny KD , Wilkes AL , McDonald CM , Denson DJ , Neumann MS . AIDS Behav 2017 22 (1) 43-63 National HIV prevention goals call for interventions that address Continuum of HIV Care (CoC) for persons living with HIV. Electronic health (eHealth) can leverage technology to rapidly develop and disseminate such interventions. We conducted a qualitative review to synthesize (a) technology types, (b) CoC outcomes, (c) theoretical frameworks, and (d) behavior change mechanisms. This rapid review of eHealth, HIV-related articles (2007-2017) focused on technology-based interventions that reported CoC-related outcomes. Forty-five studies met inclusion criteria. Mobile texting was the most commonly reported technology (44.4%, k = 20). About 75% (k = 34) of studies showed proven or preliminary efficacy for improving CoC-related outcomes. Most studies (60%, k = 27) focused on medication adherence; 20% (k = 9) measured virologic suppression. Many eHealth interventions with preliminary or proven efficacy relied on mobile technology and integrated knowledge/cognition as behavior change mechanisms. This review identified gaps in development and application of eHealth interventions regarding CoC. |
The associations of resilience and HIV risk behaviors among black gay, bisexual, other men who have sex with men (MSM) in the Deep South: The MARI Study
McNair OS , Gipson JA , Denson D , Thompson DV , Sutton MY , Hickson DA . AIDS Behav 2017 22 (5) 1679-1687 Resilience is an understudied intrapersonal factor that may reduce HIV risk among men who have sex with men (MSM). Multivariable Poisson regression models were used to estimate the prevalence ratio (PR) of sexual risk behaviors, HIV prevalence, and history of sexually transmitted infections (STIs) with resilience scores in a population-based study among 364 black MSM in the Deep South. Participants with higher resilience scores had a lower prevalence of condomless anal sex with casual sexual partners in past 12 months (PR = 0.80, p value = 0.001) and during their last sexual encounter (PR = 0.81; p value = 0.009). Resilience was inversely associated with a lower prevalence of condomless anal sex with main sexual partners, participating in a sex party/orgy and having a STI in the past 12 months. Resilience may have a protective effect on HIV among black MSM, especially in the Deep South, and should be further explored in studies with prospective designs. |
