PRELIMINARY IMPACT OF SUPPORTIVE HOUSING ON HOSPITAL UTILIZATION FOR INDIVIDUALS EXPERIENCING HOMELESSNESS.

Housing instability has been shown to negatively impact physical and mental health, with a corresponding increase in health care utilization. In 2019, through a Maryland Medicaid 1115 Health Choice Waiver, 10 Baltimore city hospitals joined with the city of Baltimore and the local nonprofit Health Care for the Homeless to support an innovative program that provides permanent housing and wraparound services to individuals at risk of homelessness. Here, we describe the inception of the program and its subsequent expansion with the investment of the city hospitals. Participants in the program experienced a 48% reduction in all hospital visits and a 51% reduction in emergency department visits in the 12 months following their receipt of housing compared to the 12 months before enrollment. These data suggest the potential health benefits of housing and supportive services as an intervention.

Community-Academic Partnerships for Health Research: An Iterative and Transparent Process of Patient Engagement Before the Research Begins.

Background: The root causes of coronavirus disease 2019 (COVID-19) disparities include longstanding systemic racial bias in economic advancement and care delivery, discrimination, lack of access, and social determinants of health. To address these causes, research institutions and health care systems must shift their lens from one that focuses solely on changing behaviors among underserved and vulnerable populations to one that is inward facing. Methods: We worked with a community advisory board and an African American church that has partnered on research for more than a decade to identify community norms, needs, and key resources needed for establishing community-academic partnerships for COVID-19 testing. Participants were purposefully sampled with equal representation from 3 groups: (1) church members and leaders, (2) academic or organization researchers with experience in community-engaged research, and (3) community members with experience participating in community-engaged research. Participants engaged in a hands-on exercise in the church basement as part of a town hall-style meeting. Results: Active discussion led to the identification of business model components salient to COVID-19 testing in an underserved Baltimore community, predominantly made up of African Americans. Our discussion identified key partners, activities, resources, costs, value propositions, community relationships, community groups, communication channels, and outputs for community buy-in. Conclusion: Developing the business case for mutual trustworthiness to be better prepared for future pandemics and public health crises may foster more sustainable community-academic partnerships. Using a Business Model Canvas, we delineate the major components, activities, and value propositions that are needed to achieve authentic community-academic partnerships to advance health equity.

Hospital-to-Home-Health Transition Quality (H3TQ) Index: Further Evidence on its Validity and Recommendations for Implementation.

BACKGROUND: We developed the Hospital-to-Home-Health Transition Quality (H3TQ) Index for skilled home healthcare (HH) agencies to identify threats to safe, high-quality care transitions in real time. OBJECTIVE: Assess the validity of H3TQ in a large sample across diverse communities. RESEARCH DESIGN: A survey of recently hospitalized older adults referred for skilled HH services and their HH provider at two large HH agencies in Baltimore, MD, and New York, NY. SUBJECTS: There were five hundred eighty-seven participants (309 older adults, 141 informal caregivers, and 137 HH providers). Older adults, caregivers, and HH providers rated 747 unique transitions. Of these, 403 were rated by both the older adult/caregiver and their HH provider, whereas the remaining transitions were rated by either party. MEASURES: Construct, concurrent, and predictive validity were assessed via the overall H3TQ rating, correlation with the care transition measure (CTM), and the Medicare Outcome and Assessment Information Set (OASIS). RESULTS: Proportion of transitions with quality issues as identified by HH providers and older adults/caregivers, respectively; Baltimore 55%, 35%; NYC 43%, 32%. Older adults/caregivers across sites rated their transitions as higher quality than did providers (P<0.05). H3TQ summed scores showed construct validity with the CTM-3 and concurrent validity with OASIS measures. Summed H3TQ scores were not significantly correlated with 30-day ED visits or rehospitalization. CONCLUSIONS: The H3TQ identifies care transition quality issues in real-time and demonstrated construct and concurrent validity, but not predictive validity. Findings demonstrate value in collecting multiple perspectives to evaluate care transition quality. Implementing the H3TQ could help identify transition-quality intervention opportunities for HH patients.

Factors and Perceptions Associated with Post-Pandemic Food Sourcing and Dietary Patterns among Urban Corner Store Customers in Baltimore, Maryland.

OBJECTIVE: Diet-related disease is rising, disproportionately affecting minority communities in which small food retail stores swamp supermarkets. Barriers to healthy food access were exacerbated by the pandemic. We examined the following: (1) individual- and household-level factors in a sample of Baltimore community members who regularly shop at corner stores and (2) how these factors are associated with indicators of dietary quality. DESIGN: Cross-sectional data were collected using an online survey to capture sociodemographics, anthropometrics, and food sourcing, spending, and consumption patterns. Concurrent quantitative and qualitative analyses were conducted in Stata 18 and ATLAS.ti. SETTING: This study was set in Baltimore, Maryland, USA. PARTICIPANTS: The participants included adults (n = 127) living or working in Baltimore who identified as regular customers of their neighborhood corner store. RESULTS: The respondents were majority Black and low-income, with a high prevalence of food insecurity (62.2%) and overweight/obesity (66.9%). Most (82.76%) shopped in their neighborhood corner store weekly. One-third (33.4%) of beverage calories were attributed to sugar-sweetened beverages, and few met the recommended servings for fruits and vegetables or fiber (27.2% and 10.4%, respectively). Being Black and not owning a home were associated with lower beverage and fiber intake, and not owning a home was also associated with lower fruit and vegetable intake. Food insecurity was associated with higher beverage intake, while WIC enrollment was associated with higher fruit and vegetable and fiber intakes. Open-ended responses contextualized post-pandemic food sourcing and consumption in this setting. CONCLUSIONS: This paper helps characterize the consumers of a complex urban food system. The findings will inform future strategies for consumer-engaged improvement of local food environments.

Academic Medical Centers and Federally Qualified Health Centers: Collaboration for the Care of Underserved Communities.

Academic Medical Centers (AMCs) and Federally Qualified Health Centers (FQHCs) are similarly tasked with managing the health of their local community, yet they each face unique challenges in their ability to do so. Integrating AMCs and FQHCs into novel care delivery models can leverage both organizations strengths, providing care in a comprehensive and sustainable fashion. Johns Hopkins Medicine (JHM) implemented this model with a large East Baltimore medical center, creating an AMC-FQHC collaboration focused on providing care to the East Baltimore patient population. This system provided various improvements in care delivery, including increased staffing, new wraparound services, improved access to funding dollars, and decreased out of pocket costs for patients qualifying for financial assistance. The academic missions of research and training were preserved, serving as the primary continuity clinic for several residency programs and as a community site for research. These changes resulted in more robust care for patients while improving the financial standing of the clinic. Through AMC and FQHC partnership, progress can be made toward providing holistic and financially sustainable primary care services in underserved areas while preserving the tripartite mission of academic medicine, with significant pedagogical and research opportunities.

Design of a Mobile App Interface That Engages Community Members in a Food System Pilot Study.

Supermarkets are scarce in many under-resourced urban communities, and small independently owned retail stores often carry few fresh or healthy items. The Baltimore Urban food Distribution (BUD) mobile application (app) was previously developed to address supply-side challenges in moving healthy foods from local suppliers to retailers. In-app opportunities for consumers to indicate demand for these foods are crucial, but remain absent. We sought to understand community members' perspectives on the overall role, function and features of a proposed consumer-engagement module (BUDConnect) to expand the BUD app. A series of initial high-fidelity wireframe mockups were developed based on formative research. In-depth interviews (n = 20) were conducted and thematically analyzed using ATLAS.ti Web. Participants revealed a desire for real-time crowd-sourced information to navigate their food environments safely and effectively, functionality to help build community and social networks among store owners and their customers, opportunities to share positive reviews and ratings of store quality and offerings, and interoperability with existing apps. Rewards and referral systems resulting in the discounted purchasing of promoted healthy items were suggested to increase adoption and sustained app use. Wireframe mockups were further refined for future development and integration into the BUD app, the program and policy implications of which are discussed.

Colocating Syringe Services, COVID-19 Vaccination, And Infectious Disease Testing: Baltimore's Experience.

People who inject drugs face many challenges that contribute to poor health outcomes, including drug overdose, HIV, and hepatitis C infections. These conditions require high-quality prevention and treatment services. Syringe services programs are evidence-based harm reduction programs, and they have established track records with people who inject drugs, earning them deep trust within this population. In Baltimore, Maryland, although many syringe support services were limited during the COVID-19 pandemic, the health department's syringe services programs remained operational, allowing for the continuation of harm reduction services, including naloxone distribution. This evaluation describes a collaborative effort to colocate infectious disease testing and COVID-19 vaccination with a syringe services program. Our evaluation demonstrated that colocation of important services with trusted community partners can facilitate engagement and is essential for service uptake. Maintaining adequate and consistent funding for these services is central to program success. Colocation of other services within syringe services programs, such as medications for opioid use disorder, wound care, and infectious disease treatment, would further expand health care access for people who inject drugs.

Protocol for the Support Application for Food PAntrieS trial: design, implementation, and evaluation plan for a digital application to promote healthy food access and support food pantry operations.

Introduction: Food-insecure households commonly rely on food pantries to supplement their nutritional needs, a challenge that was underscored during the COVID-19 pandemic. Food pantries, and the food banks that supply them, face common challenges in meeting variable client volume and dietary needs under normal and emergency (e.g., pandemic, natural disaster) conditions. A scalable digital strategy that has the capacity to streamline the emergency food distribution system, while promoting healthy food options, managing volunteer recruitment and training, and connecting to emergency management systems in times of need, is urgently required. To address this gap, we are developing a working mobile application (app) called the Support Application for Food PAntrieS (SAFPAS) and will evaluate its feasibility and impact on food pantry staff preparedness, stocking, and client uptake of healthful foods and beverages in two urban United States settings. Methods: This paper describes the protocol for a randomized controlled trial of the SAFPAS mobile application. We will conduct formative research in Baltimore, Maryland and Detroit, Michigan to develop and refine the SAFPAS app and increase scalability potential to other urban settings. Then we will test the app in 20 food pantries in Baltimore randomized to intervention or comparison. The impact of the app will be evaluated at several levels of the emergency food system, including food pantry clients (n = 360), food pantry staff and volunteers (n = 100), food pantry stock, and city agencies such as the local food bank and Office of Emergency Management. The primary outcome of the SAFPAS trial is to improve the healthfulness of the foods received by food pantry clients, measured using the Food Assessment Scoring Tool (FAST). Post-trial, we will conduct additional formative research in Detroit to prepare the app for scale-up. Discussion: We anticipate that SAFPAS will improve alignment in the supply and demand for healthy foods among food pantry clients, food pantries, and city agencies which supply food in Baltimore. Real-time, bidirectional communication between entities across the system allows for increased situational awareness at all levels during normal and emergency operations. By conducting formative research in Detroit, we hope to increase the scalability of the SAFPAS app to additional settings nationwide.

A Multicomponent Intervention (POSSIBLE) to Improve Perceived Risk for HIV Among Black Sexual Minority Men: Feasibility and Preliminary Effectiveness Pilot Study.

BACKGROUND: Increased pre-exposure prophylaxis (PrEP) use is urgently needed to substantially decrease HIV incidence among Black sexual minority men. Low perceived risk for HIV (PRH) is a key unaddressed PrEP barrier for Black sexual minority men. Peers and smartphone apps are popular intervention tools to promote community health behaviors, but few studies have used these together in a multicomponent strategy. Therefore, we designed a multicomponent intervention called POSSIBLE that used an existing smartphone app called PrEPme (Emocha Mobile Health, Inc) and a peer change agent (PCA) to increase PRH as a gateway to PrEP. OBJECTIVE: This paper aims to describe the feasibility and preliminary impact of POSSIBLE on PRH and willingness to accept a PrEP referral among Black sexual minority men. METHODS: POSSIBLE was a theoretically guided, single-group, 2-session pilot study conducted among Black sexual minority men from Baltimore, Maryland between 2019 and 2021 (N=69). POSSIBLE integrated a PCA and the PrEPme app that allows users to self-monitor sexual risk behaviors and chat with the in-app community health worker to obtain PrEP service information. PRH was assessed using the 8-item PRH scale before and after baseline and follow-up study visits. At the end of each study visit, the PCA referred interested individuals to the community health worker to learn more about PrEP service options. RESULTS: The average age of participants was 32.5 (SD 8.1, range 19-62) years. In total, 55 (80%) participants were retained for follow-up at month 1. After baseline sessions, 29 (42%) participants were willing to be referred to PrEP services, 20 (69%) of those confirmed scheduled appointments with PrEP care teams. There were no statistically significant differences in PRH between baseline and follow-up visits (t122=-1.36; P=.17). CONCLUSIONS: We observed no statistically significant improvement in PRH between baseline and month 1. However, given the high retention rate and acceptability, POSSIBLE may be feasible to implement. Future research should test a statistically powered peer-based approach on PrEP initiation among Black sexual minority men.

PREVALENCE OF OCULAR ABNORMALITIES AND NORMAL DIAGNOSTIC PARAMETERS IN TWO GROUPS OF PANAMANIAN GOLDEN FROGS (ATELOPUS ZETEKI).

Panamanian golden frog (PGF) (Atelopus zeteki) is a critically endangered species. The Maryland Zoo in Baltimore houses two groups of PGF originating from distinct geographic locations as an assurance colony, with the goal of upholding genetics for future release of individuals back to their native environment. The purpose of this cross-sectional study was to characterize the prevalence of ocular abnormalities in these two zoo-housed populations of PGF as well as to establish normal parameters for selected diagnostic tests in these groups. Twenty-five females and 25 males were randomly selected from each group (100 PGF; 200 eyes in total) to undergo ocular examination using slit lamp biomicroscopy and direct ophthalmoscopy. Endodontic absorbent paper point test (EAPPT) and intraocular pressure (IOP) and Rose Bengal stain diagnostic tests were also performed. Reference ranges for tear production (EAPPT, 0.5-3 mm/min) and IOP (14-26 mmHg) were calculated in the nondiseased PGF eyes (n = 160 eyes). Rose Bengal stain uptake was negative on all eyes. In total, 40 eyes of 30 PGF were found to have some form of ocular abnormality (28% of PGF, 20% of eyes). The most frequently observed ocular abnormalities were cataract (9% of PGF, 6% of eyes) and keratitis (nonlipid keratopathy; 10% of PGF, 5.5% of eyes). There was no significant difference in overall ocular abnormality prevalence between the two groups studied (P = 0.37) or between the sexes (P = 0.76). The median age of an eye with cataract and keratitis (nonlipid keratopathy) was 10.35 and 7.7 yr, respectively. Ocular abnormalities are common in these two populations of PGF. Documentation of these ocular abnormalities and establishment of diagnostic reference ranges have not previously been published and may be important for maintaining the health of this endangered species.

Longitudinal decline in peak V̇o2 with aging in a healthy population is associated with a reduction in peripheral oxygen utilization but not in cardiac output.

Aging is associated with a significant decline in aerobic capacity assessed by maximal exercise oxygen consumption (V̇o2max). The relative contributions of the specific V̇o2 components driving this decline, namely cardiac output (CO) and arteriovenous oxygen difference (A - V)O2, remain unclear. We examined this issue by analyzing data from 99 community-dwelling participants (baseline age: 21-96 yr old; average follow-up: 12.6 yr old) from the Baltimore Longitudinal Study of Aging, free of clinical cardiovascular disease. V̇o2peak, a surrogate of V̇o2max, was used to assess aerobic capacity during upright cycle ergometry. Peak exercise left ventricular volumes, heart rate, and CO were estimated using repeated gated cardiac blood pool scans. The Fick equation was used to calculate (A - V)O2diff,peak from COpeak and V̇o2peak. In unadjusted models, V̇o2peak, (A - V)O2diff,peak, and COpeak declined longitudinally over time at steady rates with advancing age. In multiple linear regression models adjusting for baseline values and peak workload, however, steeper declines in V̇o2peak and (A - V)O2diff,peak were observed with advanced entry age but not in COpeak. The association between the declines in V̇o2peak and (A - V)O2diff,peak was stronger among those ≥50 yr old compared with their younger counterparts, but the difference between the two age groups did not reach statistical significance. These findings suggest that age-associated impairment of peripheral oxygen utilization during maximal exercise poses a stronger limitation on peak V̇o2 than that of CO. Future studies examining interventions targeting the structure and function of peripheral muscles and their vasculature to mitigate age-associated declines in (A - V)O2diff are warranted.NEW & NOTEWORTHY The age-associated decline in aerobic exercise performance over an average of 13 yr in community-dwelling healthy individuals is more closely associated with decreased peripheral oxygen utilization rather than decreased cardiac output. This association was more evident in older than younger individuals. These findings suggest that future studies with larger samples examine whether these associations vary across the age range and whether the decline in cardiac output plays a greater role earlier in life. In addition, studies focused on determinants of peripheral oxygen uptake by exercising muscle may guide the selection of preventive strategies designed to maintain physical fitness with advancing age.

Recent use of consumer and personal care products and exposures to select endocrine disrupting chemicals among urban children with asthma.

BACKGROUND: Emerging studies suggest that endocrine disrupting chemicals (EDCs) in personal care and other consumer products are linked with various adverse health effects, including respiratory and reproductive effects. Despite Black persons using more personal care products than other demographic groups and having a high asthma burden, little is known regarding their consumer product use patterns and associated EDC exposures. OBJECTIVE: To examine the association between recent exposure to select EDCs with specific consumer products and behaviors in a cohort of 110 predominantly Black children with asthma, ages 8-17 years, living in Baltimore City, Maryland. METHODS: We quantified concentrations of bisphenol A (BPA), bisphenol S (BPS), bisphenol F, two dichlorophenols, four parabens, triclosan, benzophenone-3, and triclocarban in spot urine samples. Questionnaires were used to capture recent (last 24-h) consumer product use and behaviors. Associations between EDCs and consumer product uses/behaviors were assessed using multivariable linear regression, adjusting for age, gender, race/ethnicity, and caregiver income level. Effect estimates were expressed as geometric mean ratios of biomarker concentrations of product-users vs non-users. RESULTS: Increased concentrations to select EDCs were associated with recent use of air freshener (ratios; BPA: 1.9, 95%CI 1.4-2; BPS 1.7, 95%CI 1-2.97; propyl paraben: 3.0, 95%CI 1.6-5.6), scented candles (methyl paraben: 2.6, 95%CI 1.1-6.1), and scented carpet powder (2,5-dichlorophenol: 2.8, 95%CI 1.2-6.3). Additionally, consuming canned food was associated with some increased biomarker concentrations (ratios: BPA: 1.7, 95%CI 1.2-2.4; BPS: 2.1, 95% CI: 1.2-3.6). SIGNIFICANCE: These findings add to the body of evidence suggesting that recent use of select consumer products in Black children contributes to exposure of chemicals of concern and could potentially inform exposure mitigation interventions. Findings have broad potential health implications for pediatric populations and Black children who may face exposure and health disparities. IMPACT: Little is known about how children's personal care product use and consumer behaviors affect their exposures to endocrine disrupting chemicals (EDCs). This is particularly true for Black children who often experience a disparate exposure burden to many EDCs. This is a significant knowledge gap among children that are uniquely vulnerable to EDCs as they undergo critical windows of growth and development. Our findings show associations between consumer products and EDC exposures in predominantly Black children in low-income settings. Identifying EDC exposure determinants has broad health implications as many of these chemicals have been associated with adverse health risks.

Survey of pain and stigma experiences in people diagnosed with mpox in Baltimore, Maryland during 2022 global outbreak.

A high prevalence of mpox in men who have sex with men and in people with HIV, plus visually striking and contagious lesions, have raised concerns for mpox stigma. 24 PCR-confirmed mpox patients were surveyed over the course of three months, utilizing an mpox stigma scale adapted from the HIV Stigma Scale plus assessment of pain, analgesic efficacy, and healthcare experiences. Participants were cis-male (100%), with male sexual partners (96%), mostly African-American (88%), and living with HIV (79%). Patients answered 4-16 of 24 (mean 10) stigma questions affirmatively, particularly related to negative effects of mpox on the LGBTQ community. 79% reported pain, most commonly of limbs and perianal area, with perianal pain being rated most severe. The most effective pain relief occurred with opioids (100% major relief, n = 2) and tecovirimat (63% major relief, 25% moderate, n = 16). Patients were satisfied with care provided at the studied clinics, but had negative experiences at all other mentioned sites.

The Quality of Menu Offerings in Independently Owned Restaurants in Baltimore, Maryland: Results from Mixed-Methods Formative Research for the FRESH Trial.

(1) Background: Independently owned restaurants (IORs) are prevalent in under-resourced racial and ethnic minority communities in the US and present a unique setting for public health nutrition interventions. (2) Methods: We conducted 14 in-depth interviews with IOR owners in Baltimore about their perceptions of healthy food, and customers' acceptance of healthier menus and cooking methods and concurrent observations of the availability of healthy options on their menus. Qualitative data were coded and analyzed using ATLAS.ti. Observations were analyzed with statistical analysis performed in R. (3) Results: Owners perceived non-fried options, lean proteins, and plant-based meals as healthy. While open to using healthier cooking fats, they had mixed feelings about reducing salt, adopting non-frying methods for cooking, and adding vegetables and whole grains to the menu, and were reluctant to reduce sugar in recipes and beverages. Only 17.5% of 1019 foods and 27.6% of 174 beverages in these IORs were healthy, with no significant differences in the healthfulness of restaurant offerings within low-healthy-food-access/low-income neighborhoods and those outside. (4) Conclusion: Healthy options are generally scarce in Baltimore's IORs. Insights from owners inform future interventions to tailor healthy menu offerings that are well-received by customers and feasible for implementation.

An evaluation of the impact of social and structural determinants of health on forgone care during the COVID-19 pandemic in Baltimore, Maryland.

Evidence suggests that reductions in healthcare utilization, including forgone care, during the COVID-19 pandemic may be contributing towards excess morbidity and mortality. The objective of this study was to describe individual and community-level correlates of forgone care during the COVID-19 pandemic. We conducted a cross-sectional, secondary data analysis of participants (n = 2,003) who reported needing healthcare in two population-representative surveys conducted in Baltimore, MD in 2021 and 2021-2022. Abstracted data included the experience of forgone care, socio-demographic data, comorbidities, financial strain, and community of residence. Participant's community of residence were linked with data acquired from the Baltimore Neighborhood Indicators Alliance relevant to healthcare access and utilization, including walkability and internet access, among others. The data were analyzed using weighted random effects logistic regression. Individual-level factors found to be associated with increased odds for forgone care included individuals age 35-49 (compared to 18-34), female sex, experiencing housing insecurity during the pandemic, and the presence of functional limitations and mental illness. Black/African American individuals were found to have reduced odds of forgone care, compared to any other race. No community-level factors were significant in the multilevel analyses. Moving forward, it will be critical that health systems identify ways to address any barriers to care that populations might be experiencing, such as the use of mobile health services or telemedicine platforms. Additionally, public health emergency preparedness planning efforts must account for the unique needs of communities during future crises, to ensure that their health needs can continue to be met. Finally, additional research is needed to better understand how healthcare access and utilization practices have changed during versus before the pandemic.

Need for informed providers: exploring LA-PrEP access in focus groups with PrEP-indicated communities in Baltimore, Maryland.

BACKGROUND: The approval of long-acting pre-exposure prophylaxis PrEP (LA-PrEP) in the United States brings opportunities to overcome barriers of oral PrEP, particularly among sexual and gender minority communities who bear a higher HIV burden. Little is known about real-time decision-making among potential PrEP users of LA-PrEP post-licensure. METHODS: We held focus group discussions with people assigned male at birth who have sex with men in Baltimore, Maryland to explore decision-making, values, and priorities surrounding PrEP usage. A sexual and gender minority-affirming health center that provides PrEP services supported recruitment. Discussions included a pile-sorting activity and were audio-recorded. Recordings were transcribed and analyzed iteratively, combining an inductive and deductive approach. RESULTS: We held five focus groups from Jan-June 2023 with 23 participants (21 cisgender men who have sex with men, two transgender women who have sex with men; mean age 37). Among participants, 21 were on oral PrEP, one was on injectable PrEP, and one had never taken PrEP. Most had never heard about LA-PrEP. When making decisions about PrEP, participants particularly valued efficacy in preventing HIV, side effects, feeling a sense of security, and ease of use. Perceptions varied between whether oral or injectable PrEP was more convenient, but participants valued the new opportunity for a choice in modality. Factors influencing PrEP access included cost, individual awareness, provider awareness, and level of comfort in a healthcare environment. Participants emphasized how few providers are informed about PrEP, placing the burden of being informed about PrEP on them. Comfort and trust in a provider superseded proximity as considerations for if and where to access PrEP. CONCLUSIONS: There is still low awareness about LA-PrEP among sexual and gender minority communities; thus, healthcare providers have a critical role in influencing access to LA-PrEP. Despite this, providers are still vastly underinformed about PrEP and underprepared to support clients in contextualized ways. Clients are more likely to engage in care with affirming providers who offer non-judgmental conversations about sex and life experiences. Provider education in the United States is urgently needed to better support clients in choosing a PrEP modality that is right for them and supporting adherence for effective HIV prevention.

Structural and social changes due to the COVID-19 pandemic and their impact on engagement in substance use disorder treatment services: a qualitative study among people with a recent history of injection drug use in Baltimore, Maryland.

BACKGROUND: Substance use disorder treatment and recovery support services are critical for achieving and maintaining recovery. There are limited data on how structural and social changes due to the COVID-19 pandemic impacted individual-level experiences with substance use disorder treatment-related services among community-based samples of people who inject drugs. METHODS: People with a recent history of injection drug use who were enrolled in the community-based AIDS Linked to the IntraVenous Experience study in Baltimore, Maryland participated in a one-time, semi-structured interview between July 2021 and February 2022 about their experiences living through the COVID-19 pandemic (n = 28). An iterative inductive coding process was used to identify themes describing how structural and social changes due to the COVID-19 pandemic affected participants' experiences with substance use disorder treatment-related services. RESULTS: The median age of participants was 54 years (range = 24-73); 10 (36%) participants were female, 16 (57%) were non-Hispanic Black, and 8 (29%) were living with HIV. We identified several structural and social changes due the pandemic that acted as barriers and facilitators to individual-level engagement in treatment with medications for opioid use disorder (MOUD) and recovery support services (e.g., support group meetings). New take-home methadone flexibility policies temporarily facilitated engagement in MOUD treatment, but other pre-existing rigid policies and practices (e.g., zero-tolerance) were counteracting barriers. Changes in the illicit drug market were both a facilitator and barrier to MOUD treatment. Decreased availability and pandemic-related adaptations to in-person services were a barrier to recovery support services. While telehealth expansion facilitated engagement in recovery support group meetings for some participants, other participants faced digital and technological barriers. These changes in service provision also led to diminished perceived quality of both virtual and in-person recovery support group meetings. However, a facilitator of recovery support was increased accessibility of individual service providers (e.g., counselors and Sponsors). CONCLUSIONS: Structural and social changes across several socioecological levels created new barriers and facilitators of individual-level engagement in substance use disorder treatment-related services. Multilevel interventions are needed to improve access to and engagement in high-quality substance use disorder treatment and recovery support services among people who inject drugs.

Differences in Daily Physical Activity by Alzheimer's Risk Markers Among Older Adults.

BACKGROUND: Daily physical activity patterns differ by Alzheimer's disease (AD) status and might signal cognitive risk. It is critical to understand whether patterns are disrupted early in the AD pathological process. Yet, whether established AD risk markers (ß-amyloid [Aß] or apolipoprotein E-ε4 [APOE-ε4]) are associated with differences in objectively measured activity patterns among cognitively unimpaired older adults is unclear. METHODS: Wrist accelerometry, brain Aß (+/-), and APOE-ε4 genotype were collected in 106 (Aß) and 472 (APOE-ε4) participants (mean age 76 [standard deviation{SD}: 8.5) or 75 [SD: 9.2] years, 60% or 58% women) in the Baltimore Longitudinal Study of Aging. Adjusted linear and function-on-scalar regression models examined whether Aß or APOE-ε4 status was cross-sectionally associated with activity patterns (amount, variability, or fragmentation) overall and by time of day, respectively. Differences in activity patterns by combinations of Aß and APOE-ε4 status were descriptively examined (n = 105). RESULTS: There were no differences in any activity pattern by Aß or APOE-ε4 status overall. Aß+ was associated with lower total amount and lower within-day variability of physical activity overnight and early evening, and APOE-ε4 carriers had higher total amount of activity in the evening and lower within-day variability of activity in the morning. Diurnal curves of activity were blunted among those with Aß+ regardless of APOE-ε4 status, but only when including older adults with mild cognitive impairment/dementia. CONCLUSIONS: Aß+ in cognitively unimpaired older adults might manifest as lower amount and variability of daily physical activity, particularly during overnight/evening hours. Future research is needed to examine changes in activity patterns in larger samples and by other AD biomarkers.

Baltimore oral epidemiology, disease effects, and HIV evaluation study (BEEHIVE) study protocol: a prospective cohort study.

BACKGROUND: As antiretroviral therapy has become widely available and highly effective, HIV has evolved to a manageable, chronic disease. Despite this health advancement, people living with HIV (PLWH) are at an increased risk for age-related non-communicable diseases (NCDs) compared to HIV-uninfected individuals. Similarly, PLWH are at an increased risk for selected oral diseases. PLWH with a history of injecting drugs experience an even greater burden of disease than their counterparts. The overall objective of the Baltimore Oral Epidemiology, Disease Effects, and HIV Evaluation (BEEHIVE) study is to determine the combined effects of HIV infection and NCDs on oral health status. The specific aims of the study are to: (1) determine to what extent HIV status influences access to and utilization of oral health care services; (2) determine to what extent HIV status affects self-reported and clinical oral health status; (3) determine to what extent HIV status influences the progression of periodontitis; and (4) determine to what extent HIV status impacts the periodontitis-associated oral microbiome signature. METHODS: The BEEHIVE study uses a prospective cohort study design to collect data from participants at baseline and at a 24-month follow-up visit. Data are collected through questionnaire assessments, clinical examinations, and evaluation of oral microbiological samples to determine the drivers of oral disease among a high-risk population of PLWH with a history of injection drug use and prevalent comorbid NCDs. The established AIDS Linked to the Intravenous Experience (ALIVE) cohort serves as the source of participants for the BEEHIVE Study. DISCUSSION: Upon completion of the BEEHIVE study, the knowledge gained will be important in informing future clinical and preventive interventions that can be implemented into medical and dental practice to ultimately help eliminate long-standing oral health inequities that PLWH experience.
