Objectives. HIV preexposure prophylaxis (PrEP) use has increased since its US Food and Drug Administration approval in 2012. Our objective was to describe trends in PrEP use by US women. Methods. Using national pharmacy and HIV surveillance data, we calculated the PrEP-to-diagnosis ratio (PDR), a measure of PrEP prescriptions each year compared with HIV diagnoses the previous year, for women from 2017 to 2023. We also calculated PDRs in 2023 for the 20 counties with the highest numbers of diagnosed HIV infections among women and reviewed reports of public health activities conducted by recipients of Centers for Disease Control and Prevention HIV prevention funding. Results. The PDR for women was 1.5 in 2017, and it increased to 5.8 by 2023. In the 20 counties with the highest number of diagnosed HIV infections among women, PDRs ranged from 2.2 to 16.9. Counties with the highest PDRs conducted PrEP activities designed for women. Conclusions. PrEP is a highly effective HIV prevention intervention that can empower women to protect their health, but its use has been low. Public health and clinical interventions designed for women can increase their PrEP use and support ending the US HIV epidemic. (Am J Public Health.

Transgender youth are disproportionately affected by HIV, particularly minoritized youth in the US south. To understand HIV service use among transgender youth, we interviewed 25 young racial and ethnic minority clients of four southern community-based HIV service organizations (CBOs), and CBO staff (n = 12), about service access and use. Participants were assigned male at birth and identified as female (n = 8), transgender (n = 11) or gender-fluid or nonbinary (n = 6). The majority were Black/African American or mixed race; four were Hispanic or Latino/a. Most were unemployed; nearly half were unstably housed or homeless during the prior year. Four service types were each used by approximately two-thirds of participants: counseling/support, HIV/STD testing/education, pre-exposure prophylaxis education/prescriptions, and transgender-related medical services (primarily hormone provision). Just over a quarter used social services (e.g., housing, employment). Key facilitators to service use included a non-stigmatizing CBO atmosphere, and easy and convenient access. Poor access (e.g., inconvenient hours, location), lack of transportation or parking, social service needs, and lack of money were barriers. Qualitative reports highlighted unmet social service needs, particularly housing, especially for those without HIV. To reduce disparities, HIV prevention for racial and ethnic minoritized transgender youth should simultaneously address hormone provision, HIV risk reduction and social service needs.

Compared with traditional measures of scientific impact, the CDC Science Impact Framework more broadly, directly, and quickly assesses impact of public health science. For 20 CDC-funded HIV prevention projects that were conducted during 2018-2022, health departments documented impact, based on CDC Science Impact Framework domains: Disseminating Science, Creating Awareness, Catalyzing Action, Effecting Change, and Shaping the Future. Health departments reported 282 impacts: the most common were new partnerships (n = 17, Catalyzing Action), capacity building (n = 16, Effecting Change), new projects or initiatives begun (n = 15, Shaping the Future), new collaborations (n = 14, Catalyzing Action), improved program (n = 13, Shaping the Future), new guidelines or practices (n = 13, Effecting Change), and informed persons affected by work (n = 13, Creating Awareness). Health departments documented substantial impact with a simple, timely, and broad approach. Demonstrating impact is important for community-based organizations, funders, and others interested in public health and helps them better understand the value of public health.

OBJECTIVE: This study was undertaken to estimate incidence of rare epilepsies and compare with literature. METHODS: We used electronic health record text search to identify children with 28 rare epilepsies in New York City (2010-2014). We estimated cumulative incidence and compared with literature. RESULTS: Eight of 28 rare epilepsies had five or more prior estimates, and our measurements were within the published range for all. The most common were infantile epileptic spasms syndrome (1 in 2920 live births), Lennox-Gastaut syndrome (1 in 9690), and seizures associated with tuberous sclerosis complex (1 in 14 300). Fifteen of 28 had fewer than five prior estimates, and of these, we provided additional estimates for early infantile developmental and epileptic encephalopathy (1 in 32 700), epilepsy with myoclonic-atonic seizures (1 in 34 100), Sturge-Weber syndrome plus seizures/epilepsy (1 in 40 900), epilepsy in infancy with migrating focal seizures (1 in 54 500), Aicardi syndrome plus seizures/epilepsy (1 in 71 600), hypothalamic hamartoma with seizures (1 in 225 000), and Rasmussen syndrome (1 in 450 000). Five of 28 rare epilepsies had no prior estimates, and of these, we provided a new estimate for developmental/epileptic encephalopathy with spike-and-wave activation in sleep and/or continuous spikes and waves during sleep (1 in 34 100). Data were limited for the remaining 12 rare epilepsies, which were all genetic epilepsies, including PCDH19, CDKL5, Alpers disease, SCN8A, KCNQ2, SCN2A, GLUT1 deficiency, Phelan-McDermid syndrome, myoclonic epilepsy with ragged-red fibers, dup15q syndrome, ring chromosome 14, and ring chromosome 20. SIGNIFICANCE: We estimated the incidence of rare epilepsies using population-based electronic health record data and literature review. More research is needed to better estimate the incidence of genetic epilepsies with nonspecific clinical features. Electronic health records may be a valuable data source for studying rare epilepsies and other rare diseases, particularly as genetic testing becomes more widely adopted.

The first coronavirus, avian infectious bronchitis virus, was discovered in 1937 by Fred Beaudette and Charles Hudson. In 1967, June Almeida and David Tyrrell performed electron microscopy on specimens from cultures of viruses known to cause colds in humans and identified particles that resembled avian infectious bronchitis virus. Almeida coined the term “coronavirus,” from the Latin corona (“crown”), because the glycoprotein spikes of these viruses created an image similar to a solar corona (Figure).

Coronavirus virions are spherical or variable in shape and composed of an outer layer of lipid covered with a crown of club-shaped peplomers or spikes. Within each spike is a helical single-stranded RNA-containing structural protein. Although the term corona was first used in English in the 1500s, it was borrowed directly from the Latin word for “crown.” Corona is derived from the Ancient Greek κορώνη (korōnè), meaning “garland” or “wreath,” coming from a proto-Indo-European root, sker- or ker-, meaning “to turn” or “to bend.” | | In the 1967 initial description of an electron microscopic image of a human common cold virus, June Almeida (née Hart) and David Tyrrell described the surface of coronavirus particles as being “covered with a distinct layer of projections roughly 200Ǻ [20 nm] long….[with] a narrow stalk just in the limit of resolution of the microscope and a ‘head’ roughly 100Ǻ across”. In micrographs, the club-shaped spikes that stud the surface of coronaviruses are glycoproteins that give the appearance of a radiate crown.

In May 2022, CDC began an investigation of a possible increase in pediatric intracranial infections, particularly those caused by Streptococcus bacteria, during the preceding year (1). January 2016–May 2022 data from a large, geographically diverse network of children's hospitals showed altered patterns in pediatric intracranial infections after the onset of the COVID-19 pandemic (1). In this update, extended hospitalization data through March 2023 from 37 hospitals in 19 states and the District of Columbia showed a higher-than-expected number of pediatric intracranial infections beginning in August 2021, with a large peak during winter 2022–2023. Pediatric intracranial infections are recognized as a severe complication of viral respiratory infection and sinusitis (2), and the winter 2022–2023 peak coincided with spikes in respiratory virus circulation*,† (3,4). Even during this peak, intracranial infections remained rare. CDC continues to track trends in pediatric intracranial infections and recommends that all persons aged ≤18 years remain current with recommended vaccinations, including influenza and COVID-19.§

BACKGROUND: Sero-surveillance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can reveal trends and differences in subgroups and capture undetected or unreported infections that are not included in case-based surveillance systems. METHODS: Cross-sectional, convenience samples of remnant sera from clinical laboratories from 51 U.S. jurisdictions were assayed for infection-induced SARS-CoV-2 antibodies biweekly from October 25, 2020, to July 11, 2021, and monthly from September 6, 2021, to February 26, 2022. Test results were analyzed for trends in infection-induced, nucleocapsid-protein seroprevalence using mixed effects models that adjusted for demographic variables and assay type. FINDINGS: Analyses of 1,469,792 serum specimens revealed U.S. infection-induced SARS-CoV-2 seroprevalence increased from 8.0% (95% confidence interval (CI): 7.9%-8.1%) in November 2020 to 58.2% (CI: 57.4%-58.9%) in February 2022. The U.S. ratio of the change in estimated seroprevalence to the change in reported case prevalence was 2.8 (CI: 2.8-2.9) during winter 2020-2021, 2.3 (CI: 2.0-2.5) during summer 2021, and 3.1 (CI: 3.0-3.3) during winter 2021-2022. Change in seroprevalence to change in case prevalence ratios ranged from 2.6 (CI: 2.3-2.8) to 3.5 (CI: 3.3-3.7) by region in winter 2021-2022. INTERPRETATION: Ratios of the change in seroprevalence to the change in case prevalence suggest a high proportion of infections were not detected by case-based surveillance during periods of increased transmission. The largest increases in the seroprevalence to case prevalence ratios coincided with the spread of the B.1.1.529 (Omicron) variant and with increased accessibility of home testing. Ratios varied by region and season with the highest ratios in the midwestern and southern United States during winter 2021-2022. Our results demonstrate that reported case counts did not fully capture differing underlying infection rates and demonstrate the value of sero-surveillance in understanding the full burden of infection. Levels of infection-induced antibody seroprevalence, particularly spikes during periods of increased transmission, are important to contextualize vaccine effectiveness data as the susceptibility to infection of the U.S. population changes. FUNDING: This work was supported by the Centers for Disease Control and Prevention, Atlanta, Georgia.

To better understand utilization of HIV prevention, care, and treatment services by young men who have sex with men (YMSM) and young transgender persons (YTG), of Black race or Hispanic/Latino/Latina ethnicity in the U.S. South, we conducted semi-structured interviews with 127 clients at one of four community based organizations (CBOs) in Miami, Atlanta, New Orleans/Baton Rouge, or Columbia, South Carolina. Across sites, the service that most commonly drew respondents into the CBO was HIV and STD testing. Other services commonly used included HIV/STI treatment, counseling services/support groups, and PrEP services. Social/organizational/structural facilitators of service utilization include the welcoming climate/culture of the CBOs, ease of access to the services, and transportation services to reach the CBOs. Suggested service enhancements include broader range of comprehensive, navigational-type services beyond HIV testing and service co-location. Research on how to reduce stigma in the surrounding communities may help reduce health disparities experienced by these populations.

CONTEXT: Mask mandates are one form of nonpharmaceutical intervention that has been utilized to combat the spread of SARS-CoV2, the virus that causes COVID-19. OBJECTIVE: This study examines the association between state-issued mask mandates and changes in county-level and hospital referral region (HRR)-level COVID-19 hospitalizations across the United States. DESIGN: Difference-in-difference and event study models were estimated to examine the association between state-issued mask mandates and COVID-19 hospitalization outcomes. PARTICIPANTS: All analyses were conducted with US county-level data. INTERVENTIONS: State-issued mask mandates. County-level data on the mandates were collected from executive orders identified on state government Web sites from April 1, 2020, to December 31, 2020. MAIN OUTCOME MEASURES: Daily county-level (and HRR-level) estimates of inpatient beds occupied by patients with confirmed or suspected COVID-19 were collected by the US Department of Health and Human Services. RESULTS: The state issuing of mask mandates was associated with an average of 3.6 fewer daily COVID-19 hospitalizations per 100 000 people (P < .05) and a 1.2-percentage-point decrease in the percentage of county beds occupied with COVID-19 patients (P < .05) within 70 days of taking effect. Event study results suggest that this association increased the longer mask mandates were in effect. In addition, the results were robust to analyses conducted at the HRR level. CONCLUSIONS: This study demonstrated that state-issued mask mandates were associated with reduction in COVID-19 hospitalizations across the United States during the earlier portion of the pandemic. As new variants of the virus cause spikes in COVID-19 cases, reimposing mask mandates in indoor and congested public areas, as part of a layered approach to community mitigation, may reduce the spread of COVID-19 and lessen the burden on our health care system.

Rotavirus live-attenuated vaccines, both mono- and pentavalent, generate broadly heterotypic protection. B-cells isolated from adults encode neutralizing antibodies, some with affinity for VP5*, that afford broad protection in mice. We have mapped the epitope of one such antibody by determining the high-resolution cryo-EM structure of its antigen-binding fragment (Fab) bound to the virion of a candidate vaccine strain, CDC-9. The Fab contacts both the distal end of a VP5* β-barrel domain and the two VP8* lectin-like domains at the tip of a projecting spike. Its interactions with VP8* do not impinge on the likely receptor-binding site, suggesting that the mechanism of neutralization is at a step subsequent to initial attachment. We also examined structures of CDC-9 virions from two different stages of serial passaging. Nearly all the VP4 (cleaved to VP8*/VP5*) spikes on particles from the earlier passage (wild-type isolate) had transitioned from the "upright" conformation present on fully infectious virions to the "reversed" conformation that is probably the end state of membrane insertion, unable to mediate penetration, consistent with the very low in vitro infectivity of the wild-type isolate. About half the VP4 spikes were upright on particles from the later passage, which had recovered substantial in vitro infectivity but had acquired an attenuated phenotype in neonatal rats. A mutation in VP4 that occurred during passaging appears to stabilize the interface at the apex of the spike and could account for the greater stability of the upright spikes on the late-passage, attenuated isolate. IMPORTANCE Rotavirus live-attenuated vaccines generate broadly heterotypic protection, and B-cells isolated from adults encode antibodies that are broadly protective in mice. Determining the structural and mechanistic basis of broad protection can contribute to understanding the current limitations of vaccine efficacy in developing countries. The structure of an attenuated human rotavirus isolate (CDC-9) bound with the Fab fragment of a broadly heterotypic protective antibody shows that protection is probably due to inhibition of the conformational transition in the viral spike protein (VP4) critical for viral penetration, rather than to inhibition of receptor binding. A comparison of structures of CDC-9 virus particles at two stages of serial passaging supports a proposed mechanism for initial steps in rotavirus membrane penetration.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are environmental contaminants that have received significant public attention. PFAS are a large group of human-made chemicals that have been used in industry and consumer products worldwide since the 1950s. Human exposure to PFAS is a growing public health concern. Studies suggest that exposure to PFAS may increase the risk of some cancers and have negative health impacts on the endocrine, metabolic, and immune systems. Federal and state health partners are investigating the exposure to and possible health effects associated with PFAS. Government agencies can observe social media discourse on PFAS to better understand public concerns and develop targeted communication and outreach efforts. OBJECTIVE: The primary objective of this study is to understand how social media is used to share, disseminate, and engage in public discussions of PFAS-related information in the United States. METHODS: We investigated PFAS-related content across 2 social media platforms between May 1, 2017, and April 30, 2019, to identify how social media is used in the United States to seek and disseminate PFAS-related information. Our key variable of interest was posts that mentioned "PFAS," "PFOA," "PFOS," and their hashtag variations across social media platforms. Additional variables included post type, time, PFAS event, and geographic location. We examined term use and post type differences across platforms. We used descriptive statistics and regression analysis to assess the incidence of PFAS discussions and to identify the date, event, and geographic patterns. We qualitatively analyzed social media content to determine the most prevalent themes discussed on social media platforms. RESULTS: Our analysis revealed that Twitter had a significantly greater volume of PFAS-related posts compared with Reddit (98,264 vs 3126 posts). PFAS-related social media posts increased by 670% over 2 years, indicating a marked increase in social media users' interest in and awareness of PFAS. Active engagement varied across platforms, with Reddit posts demonstrating more in-depth discussions compared with passive likes and reposts among Twitter users. Spikes in PFAS discussions were evident and connected to the discovery of contamination events, media coverage, and scientific publications. Thematic analysis revealed that social media users see PFAS as a significant public health concern and seek a trusted source of information about PFAS-related public health efforts. CONCLUSIONS: The analysis identified a prevalent theme-on social media, PFAS are perceived as an immediate public health concern, which demonstrates a growing sense of urgency to understand this emerging contaminant and its potential health impacts. Government agencies can continue using social media research to better understand the changing community sentiment on PFAS and disseminate targeted information and then use social media as a forum for dispelling misinformation, communicating scientific findings, and providing resources for relevant public health services.

There is a dearth of research on the intersection of incarceration and psychological distress among men who have sex with men including African American (AAMSM) and Latino MSM (LMSM), populations which bear a large burden of HIV in the U.S. Recent incarceration is an important context to examine psychological distress given the critical implications it has on health outcomes. Using baseline data from the Latino and African American Men's Project (LAAMP), a multi-site randomized HIV behavioral intervention trial, this paper examined the association between previous incarceration within the past three months (i.e., recent incarceration) and psychological distress in the past four weeks, assessed by the Kessler Psychological Distress Scale (K10). Among 1482 AAMSM and LMSM (AAMSM: 911, LMSM: 571), we found 768 (52%) were previously incarcerated, but not in past three months and 138 (9.3%) had been recently incarcerated. After adjusting for race, education, access to resources, current living arrangement, HIV status, and substance use, participants who had been recently incarcerated were more likely to have mild psychological distress i.e., K10 score 20-24 (aRRR:1.43, 95% CI 1.20, 1.71) or severe psychological distress, i.e., K10 score > 30 (aRRR: 1.89, 95% CI 1.22, 2.93) in the past four weeks than those never incarcerated and those previously incarcerated, but not in past three months. Our findings have implications for mental health and HIV prevention services for AAMSM and LMSM with previous incarceration within the past three months.

Efforts to combat the coronavirus disease (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have placed a renewed focus on the use of transmission electron microscopy for identifying coronavirus in tissues. In attempts to attribute pathology of COVID-19 patients directly to tissue damage caused by SARS-CoV-2, investigators have inaccurately reported subcellular structures, including coated vesicles, multivesicular bodies, and vesiculating rough endoplasmic reticulum, as coronavirus particles. We describe morphologic features of coronavirus that distinguish it from subcellular structures, including particle size range (60-140 nm), intracellular particle location within membrane-bound vacuoles, and a nucleocapsid appearing in cross section as dense dots (6-12 nm) within the particles. In addition, although the characteristic spikes of coronaviruses may be visible on the virus surface, especially on extracellular particles, they are less evident in thin sections than in negative stain preparations.

Objectives. To report trends in sexual violence (SV) emergency department (ED) visits in the United States.Methods. We analyzed monthly changes in SV rates (per 100 000 ED visits) from January 2017 to December 2019 using Centers for Disease Control and Prevention's National Syndromic Surveillance Program data. We stratified the data by sex and age groups.Results. There were 196 948 SV-related ED visits from January 2017 to December 2019. Females had higher rates of SV-related ED visits than males. Across the entire time period, females aged 50 to 59 years showed the highest increase (57.33%) in SV-related ED visits, when stratified by sex and age group. In all strata examined, SV-related ED visits displayed positive trends from January 2017 to December 2019; 10 out of the 24 observed positive trends were statistically significant increases. We also observed seasonal trends with spikes in SV-related ED visits during warmer months and declines during colder months, particularly in ages 0 to 9 years and 10 to 19 years.Conclusions. We identified several significant increases in SV-related ED visits from January 2017 to December 2019. Syndromic surveillance offers near-real-time surveillance of ED visits and can aid in the prevention of SV. (Am J Public Health.

We used Google search data from January 1, 2014 to January 1, 2019 to explore public awareness of pre-exposure prophylaxis (PrEP) and HIV testing in the United States. Using two search strings, one for PrEP and one for HIV testing, we compared search volume to state HIV prevalence and new HIV diagnoses. We also used Google News to identify news events related to short-term spikes in search volume. Controlling for poverty, education, and internet access, a one-unit increase in a state's HIV prevalence rate was associated with a 3% increase in PrEP search volume (aPR = 1.03 [1.034, 1.037], P < 0.0001) and HIV testing search volume (aPR = 1.03 [1.030, 1.032], P < 0.0001). Short-term search volume spikes also coincided with celebrity news and pharmaceutical company advertising. We demonstrate that search engine data can be a powerful tool for understanding HIV knowledge-seeking and can provide key insight to the events that drive public interest about HIV online.

We read with interest the Correspondence by Zsuzsanna Varga and colleagues1 on the possible infection of endothelial cells by SARS-CoV-2 using electron microscopic (EM) images as evidence. However, we believe the EM images in the Correspondence do not show coronavirus particles but instead show cross-sections of the rough endoplasmic reticulum (RER). These spherical structures are surrounded by dark dots, which might have been interpreted as spikes on coronavirus particles but are instead ribosomes. The purported particles are free within the cytoplasm, whereas within a coronavirus-infected cell, accumulations of virus particles would be found in membrane-bound areas in the cisternae of the RER–Golgi area, where the spikes would be located on the inside of the cisternal space.2 In addition, cross-sections through the viral nucleocapsid are not seen in the interior of these structures as would be found with coronavirus particles (figure ).

BACKGROUND: Despite WHO advocating for an integrated approach to antenatal care (ANC), testing coverage for conditions other than HIV remains low and women are referred to distant laboratories for testing. Using point-of-care tests (POCTs) at peripheral dispensaries could improve access to testing and timely treatment. However, the effect of providing additional services on nurse workload and client wait times are unknown. We use discrete-event simulation (DES) modelling to understand the effect of providing four point-of-care tests for ANC on nurse utilization and wait times for women seeking maternal and child health (MCH) services. METHODS: We collected detailed time-motion data over 20 days from one high volume dispensary in western Kenya during the 8-month implementation period (2014-2015) of the intervention. We constructed a simulation model using empirical arrival distributions, activity durations and client pathways of women seeking MCH services. We removed the intervention from the model to obtain wait times, length-of-stay and nurse utilization rates for the baseline scenario where only HIV testing was offered for ANC. Additionally, we modelled a scenario where nurse consultations were set to have minimum durations for sufficient delivery of all WHO-recommended services. RESULTS: A total of 183 women visited the dispensary for MCH services and 14 of these women received point-of-care testing (POCT). The mean difference in total waiting time was 2 min (95%CI: < 1-4 min, p = 0.026) for MCH women when integrated POCT was given, and 9 min (95%CI: 4-14 min, p < 0.001) when integrated POCT with adequate ANC consult times was given compared to the baseline scenario. Mean length-of-stay increased by 2 min (95%CI: < 1-4 min, p = 0.015) with integrated POCT and by 16 min (95%CI: 10-21 min, p < 0.001) with integrated POCT and adequate consult times compared to the baseline scenario. The two nurses' overall daily utilization in the scenario with sufficient minimum consult durations were 72 and 75%. CONCLUSION: The intervention had a modest overall impact on wait times and length-of-stay for women seeking MCH services while ensuring pregnant women received essential diagnostic testing. Nurse utilization rates fluctuated among days: nurses experienced spikes in workload on some days but were under-utilized on the majority of days. Overall, our model suggests there was sufficient time to deliver all WHO's required ANC activities and offer integrated testing for ANC first and re-visits with the current number of healthcare staff. Further investigations on improving healthcare worker, availability, performance and quality of care are needed. Delivering four point-of-care tests together for ANC at dispensary level would be a low burden strategy to improve ANC.

Disclosure of same-sex behavior to health care providers (HCPs) by men who have sex with men (MSM) has been argued to be an important aspect of HIV prevention. However, Black MSM are less likely to disclose compared to white MSM. This analysis of data collected in the United States from 2006-2009 identified individual and social network characteristics of Black MSM (n = 226) that are associated with disclosure that may be leveraged to increase disclosure. Over two-thirds (68.1%) of the sample had ever disclosed to HCPs. Part-time employment (AOR = 0.32, 95% CI = 0.11-0.95), bisexual identity (AOR = 0.29, 95% CI = 0.12-0.70), and meeting criteria for alcohol use disorders (AOR = 0.32, 95% CI = 0.14-0.75) were negatively associated with disclosure. Disclosers were more likely to self-report being HIV-positive (AOR = 4.47, 95% CI = 1.54-12.98), having more frequent network socialization (AOR = 2.15, 95% CI = 1.24-3.73), and having a social network where all members knew the participant had sex with men (AOR = 4.94, 95% CI = 2.06-11.86). These associations were not moderated by self-reported HIV status. Future interventions to help MSM identify social network members to safely disclose their same-sex behavior may also help disclosure of same-sex behavior to HCPs among Black MSM.

OBJECTIVE:: The Care and Prevention in the United States (CAPUS) Demonstration Project was a 4-year (2012-2016) cross-agency demonstration project that aimed to reduce HIV/AIDS-related morbidity and mortality among racial/ethnic minority groups in 8 states (Georgia, Illinois, Louisiana, Mississippi, Missouri, North Carolina, Tennessee, and Virginia). Its goals were to increase the identification of undiagnosed HIV infections and optimize the linkage to, reengagement with, and retention in care and prevention services for people with HIV (PWH). We present descriptive findings to answer selected cross-site process and short-term outcome monitoring and evaluation questions. METHODS:: We answered a set of monitoring and evaluation questions by using data submitted by grantees. We used a descriptive qualitative method to identify key themes of activities implemented and summarized quantitative data to describe program outputs and outcomes. RESULTS:: Of 155 343 total HIV tests conducted by all grantees, 558 (0.36%) tests identified people with newly diagnosed HIV infection. Of 4952 PWH who were presumptively not in care, 1811 (36.6%) were confirmed as not in care through Data to Care programs. Navigation and other linkage, retention, and reengagement programs reached 10 382 people and linked to or reengaged with care 5425 of 7017 (77.3%) PWH who were never in care or who had dropped out of care. Programs offered capacity-building trainings to providers to improve cultural competency, developed social marketing and social media campaigns to destigmatize HIV testing and care, and expanded access to support services, such as transitional housing and vocational training. CONCLUSIONS:: CAPUS grantees substantially expanded their capacity to deliver HIV-related services and reach racial/ethnic minority groups at risk for or living with HIV infection. Our findings demonstrate the feasibility of implementing novel and integrated programs that address social and structural barriers to HIV care and prevention.

Major advances have been made in reducing HIV-related morbidity and mortality since the first infections were reported in the United States more than 36 years ago.1,2 However, racial/ethnic minority populations are disproportionately affected.3,4 The Care and Prevention in the United States (CAPUS) Demonstration Project (hereinafter, CAPUS; 2012-2016) aimed to reduce HIV-related morbidity, mortality, and health disparities among these priority populations in 8 states: Georgia, Illinois, Louisiana, Mississippi, Missouri, North Carolina, Tennessee, and Virginia.5 State health departments collectively received $42.8 million through the US Department of Health and Human Services Secretary’s Minority AIDS Initiative Fund6 to expand and improve HIV testing capacity and optimize linkage to, retention in, and reengagement with care and prevention services for people with HIV (PWH).5 Eligibility for funding was based on the high HIV disease burden among racial/ethnic minority populations, the disproportionate rate of AIDS diagnoses and associated mortality, and the pervasive effect of social and structural determinants of health within a jurisdiction.

BACKGROUND: Although head trauma-related deaths, hospitalizations, and emergency department visits are well characterized, few studies describe pediatric patients presenting outside of emergency departments. We compared the epidemiology and extent of healthcare-seeking pediatric (0-17 years) patients presenting in outpatient settings with those of patients seeking nonhospitalized emergency department care. METHODS: We used MarketScan Medicaid and commercial claims, 2004-2013, to identify patients managed in two outpatient settings (physician's offices/clinics, urgent care) and the emergency department. We then examined differences in demographic and injury-specific factors, Centers for Disease Control and Prevention-defined head trauma diagnoses, the extent of and reasons for post-index visit ambulatory care use within 30/90/180 days, and annual and monthly variations in head trauma trends. Outpatient incidence rates in 2013 provided estimates of the nationwide US outpatient burden. RESULTS: A total of 1,683,097 index visits were included, representing a nationwide burden in 2013 of 844,660 outpatient cases, a number that encompassed 51% of healthcare-seeking head trauma that year and that substantially increased in magnitude from 2004 to 2013. Two-thirds (68%) were managed in outpatient settings. While demographic distributions varied with index-visit location, injury-specific factors were comparable. Seasonal spikes appeared to coincide with school sports. CONCLUSIONS: There is an urgent need to better understand the natural history of head trauma in the >800,000 pediatric patients presenting each year for outpatient care. These outpatient injuries, which are more than double the number of head trauma cases recorded in the hospital-affiliated settings, illustrate the potential importance of expanding inclusion criteria in surveillance and prevention efforts designed to address this critical issue.

Despite the high HIV incidence and prevalence among black men who have sex with men (BMSM), little research has examined partner characteristics, partner seeking venue, sexual position, substance use, and sexual risk behavior at the sex event-level among BMSM. Using the baseline data from a multi-site study of 807 BMSM stratified by their HIV status, the goal of this study was to conduct a detailed event-level analysis of 1577 male anal sex events to assess the factors associated with condomless anal intercourse (CLAI) with a HIV-discordant or HIV status-unknown partner. We found CLAI with an HIV-discordant or unknown HIV status partner among HIV-negative BMSM was negatively associated with having sex with a main partner, and was positively associated with taking both receptive and insertive sexual positions during sex. As compared to a sex partner met at bar, night club or dance club, HIV-positive BMSM were less likely to engage in CLAI with HIV-discordant and unknown HIV status partner met at party or friend's house or at community organizations. HIV-positive BMSM had lower odds of engaging in CLAI with HIV-discordant and unknown HIV status partner if they had insertive sexual position or both receptive and insertive sexual positions. These results underscore the importance of delineating unique sex event-level factors associated with sexual risk behavior depending on individuals' HIV status. Our findings suggest event-level partner characteristics, sexual position, and partner seeking venues may contribute to disparities in HIV incidence.

Yersinia pestis is the causative agent of plague, and is considered a category A priority pathogen due to its potential for high transmissibility and the significant morbidity and mortality it causes in humans. Y. pestis is endemic to the Western United States and much of the world, necessitating programs to monitor for this pathogen on the landscape. Elevated human risk of plague infection has been spatially correlated with spikes in seropositive wildlife numbers, particularly rodent-eating carnivores which are frequently in contact with the enzootic hosts and the associated arthropod vectors of Y. pestis In this study, we describe a semi-automated bead-based flow cytometric assay developed for plague monitoring in wildlife called the F1-Luminex Plague Assay (F1-LPA). Based upon Luminex/Bio-Plex technology, the F1-LPA targets serological responses to the F1 capsular antigen of Y. pestis and was optimized to analyze antibodies eluted from wildlife blood samples preserved on Nobuto filter paper strips. In comparative evaluations using wildlife samples with passive hemagglutination, the gold standard tool for wildlife plague serodiagnosis, the F1-LPA demonstrated as much as 64x improvement in analytical sensitivity to F1-specific IgG detection, and allowed for unambiguous classification of IgG status. The functionality of the F1-LPA was demonstrated for coyotes and other canids, which are the primary sentinels in wildlife plague monitoring, as well as felids and raccoons. Additionally, assay formats that do not require species-specific immunological reagents, which are not routinely available for several wildlife species used in plague monitoring, were determined to be functional in the F1-LPA.

Gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV. MSM comprise roughly 2% of the US population, yet approximately two-thirds of new HIV infections are among MSM (Centers for Disease Control and Prevention, 2016). Additionally, significant racial and ethnic disparities exist with respect to HIV transmission among MSM. Based on the current HIV diagnoses rates in the US, about 1 in 2 African American men who have sex with men (AAMSM), 1 in 4 Latino MSM (LMSM) and 1 in 11 white MSM will be diagnosed with HIV during their lifetime (Center for Disease Control and Prevention (CDC), 2016a). In general, substance-using MSM are among the groups with the greatest risk for HIV infection (Centers for Disease Control and Prevention, 2011; Margolis, Joseph, Hirshfield, et al., 2014; Pines, Gorbach, Weiss, et al., 2014; Plankey, Ostrow, Stall, et al., 2007); nearly a third of incident HIV infections among MSM may be associated with non-injection drug use (Mansergh et al., 2008; Van Tieu & Koblin, 2009). Substance-using sexual minorities are more likely to underutilize substance use treatment (McCabe, Bostwick, Hughes, West, & Boyd, 2010) and may be an HIV transmission bridge to non-drug-using populations (Lambert et al., 2011). | With respect to alcohol use, high rates of both alcohol consumption and binge drinking have been documented among MSM populations (Finlayson et al., 2011). Additionally, previous studies have found associations between heavy drinking, as define as having 6 or more drinks on one occasion or 4 or more drinks daily, and HIV risk behaviors among MSM, such as condomless anal intercourse and greater number of sexual patterns (Colfax et al., 2004; Greenwood et al., 2001; Koblin et al., 2003a; Woolf & Maisto, 2009). Previous studies also suggest that many substance-using MSM populations engage in use of multiple substances, often concomitantly (Santos et al., 2013). There also may be a dose response with number and frequency of substances used with respect to condomless anal sex among HIV negative MSM (Santos et al., 2013). However, patterns of substance-use vary across racial and ethnic MSM populations, e.g. African American substance-using MSM being more likely to use crack/cocaine relative to other substance-using MSM populations (Goldstein, Burstyn, LeVasseur, & Welles, 2016; Halkitis & Jerome, 2008; Hatfield, Horvath, Jacoby, & Simon Rosser, 2009; Mimiaga, Reisner, Fontaine, et al., 2010; Paul, Boylan, Gregorich, Ayala, & Choi, 2014). Thus, it is important to better understand patterns of concomitant substance-use, e.g. methamphetamine, crack/cocaine and alcohol, across specific sociodemographic categories among MSM populations (Santos et al., 2013). Sociodemographic characteristics which may be particularly relevant for specific MSM populations include poverty and history of incarceration. For example, pronounced racial disparities have been found between AAMSM and other MSM populations with respect to structural barriers, such as low income, unemployment and incarceration, associated with HIV infection (Millet, Peterson, Flores, Hart, et al., 2012). Additionally, a recent study conducted by Rutledge et al, found a high proportion of MSM reporting both a history of incarceration and substance use. This study found rates of incarceration highest among men who classified themselves as “down-low”, e.g. endorsing secrecy about same-sex sexual behavior, promting the authors to posit that this population may engage in trading sex for money more often and thus increase their risk for incarceration (Rutledge, Jemmott, O'Leary, & Icard, 2016).

Black men who have sex with men (BMSM) are a population at the intersection of two minority statuses-racial minority and sexual minority. Membership in either group, compared to white or heterosexual group membership, may increase one's risk of negative childhood and adult experiences. Baseline data from an HIV intervention efficacy trial (the Black Men Evolving Study) were used to explore the prevalence of adverse childhood experiences (ACEs) among 536 BMSM and associations between ACEs and adult mental and physical health outcomes. Overall, the prevalence of ACEs was high among this sample of BMSM with almost 90% experiencing at least one ACE. Findings revealed that ACE score was significantly associated with adult mental health (AOR = 1.21, 95% CI [1.12, 1.30]), but not with adult physical health. All ACEs were significantly associated with mental health, but only physical neglect and household substance abuse were significantly associated with physical health (AOR = 1.69, 95% CI [1.02, 2.74] and AOR = 1.57, 95% CI [1.03, 2.40], respectively). The findings support the need for interventions targeting improved adult health outcomes, particularly for minority groups, to consider the impact of early adversity on health and wellness.

Young people (15-24 years) in the United States are disproportionately affected by infection with human immunodeficiency virus (HIV) and sexually transmitted diseases (STD). Shortfalls in HIV/STD-related knowledge, attitudes, beliefs, and behavioral intentions (KABI) likely contribute to this discrepancy. In this report we describe our experience developing a novel means of health communication combining entertainment-education theory and recent technological advances to create a HIV/STD-focused "motion comic." We also report the audience satisfaction and acceptance of the intervention. We used the Health Belief Model (HBM), entertainment-education (EE) principles, and the Sabido Method (SM) and conducted three rounds of focus groups to develop a 38-minute HIV/STD focused motion comic for young people between the ages 15 and 24 years. Participants indicated that motion comics were an acceptable method of delivering HIV/STD prevention messages. They also expressed satisfaction with motion comics plot, story settings, the tone of humor, and drama. Our results suggest that motion comics are a viable new method of delivering health communication messages about HIV/STD and other public health issues, and warrant further development and broader evaluation.

In the United States, young people (ages 15-24 years) are disproportionately affected by human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs), due at least in part to inadequate or incorrect HIV/STD-related knowledge, attitudes, beliefs, and behavioral intentions (KABI). Comic book narratives are a proven method of HIV/STD prevention communication to strengthen KABI for HIV/STD prevention. Motion comics, a new type of comic media, are an engaging and low-cost means of narrative storytelling. The objective of this study was to quantitatively evaluate the effectiveness of a pilot six-episode HIV/STD-focused motion comic series to improve HIV/STD-related KABI among young people. We assessed change in HIV/STD knowledge, HIV stigma, condom attitudes, HIV/STD testing attitudes, and behavioral intentions among 138 participants in 15 focus groups immediately before and after viewing the motion comic series. We used paired t-tests and indicators of overall improvement to assess differences between surveys. We found a significant decrease in HIV stigma (p < .001) and increases in both HIV knowledge (p = .002) and behavioral intentions to engage in safe sex (p < .001). In summary, this motion comic intervention improved HIV/STD-related KABI of young adult viewers by reducing HIV stigma and increasing behavioral intentions to engage in safer sex. Our results demonstrate the promise of this novel intervention and support its use to deliver health messages to young people.

Background: Identifying lung pathogens and acute spikes in lung counts remain a challenge in the treatment of patients with cystic fibrosis (CF). Bacteria from the deep lung may be sampled from aerosols produced during coughing. Methods: A new device was used to collect and measure bacteria levels from cough aerosols of patients with CF. Sputum and oral specimens were also collected and measured for comparison. Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, and Streptococcus mitis were detected in specimens using Real-Time Polymerase Chain Reaction (RT-PCR) molecular assays. Results: Twenty adult patients with CF and 10 healthy controls participated. CF related bacteria (CFRB) were detected in 13/20 (65%) cough specimens versus 15/15 (100%) sputum specimens. Commensal S. mitis was present in 0/17 (0%, p=0.0002) cough specimens and 13/14 (93%) sputum samples. In normal controls, no bacteria were collected in cough specimens but 4/10 (40%) oral specimens were positive for CFRB. Conclusions: Non-invasive cough aerosol collection may detect lower respiratory pathogens in CF patients, with similar specificity and sensitivity to rates detected by BAL, without contamination by oral CFRB or commensal bacteria.

We assessed associations of demographic, psychosocial, and substance use factors with seroadaptation strategies among 835 BMSM in four US cities. Seroadaptation strategies were practiced by 59.8 % of men, with 10.5 % practicing 100 % condom use, 26.5 % serosorting, 7.2 % condom serosorting, and 15.6 % seropositioning. In multivariable analyses, compared to men who used no seroadaptation strategies, serosorters were older, were less likely to be HIV infected, had fewer male sex partners, and had higher levels of social support and sexual self-efficacy. Condom serosorters had less psychological distress, were more likely to use methamphetamine, and had higher levels of sexual self-efficacy. Seropositioners were older, were less likely to be HIV infected, to have a main partner, and report alcohol/drug use with sex, while having higher levels of sexual self-efficacy. Seroadaptation practices among BMSM need to be considered to address perceived safer sex strategies and strengthen access to a broader reach of culturally-relevant prevention efforts.
