Incidence and risk factors of omicron variant SARS-CoV-2 breakthrough infection among vaccinated and boosted individuals.

Background: SARS-CoV-2 vaccines have been shown to be safe and effective against infection and severe COVID-19 disease worldwide. Certain co-morbid conditions cause immune dysfunction and may reduce immune response to vaccination. In contrast, those with co-morbidities may practice infection prevention strategies. Thus, the real-world clinical impact of co-morbidities on SARS-CoV-2 infection in the recent post-vaccination period is not well established. We performed this study to understand the epidemiology of Omicron breakthrough infection and evaluate associations with number of comorbidities in a vaccinated and boosted population. Methods and Findings: We performed a retrospective clinical cohort study utilizing the Northwestern Medicine Enterprise Data Warehouse. Our study population was identified as fully vaccinated adults with at least one booster. The primary risk factor of interest was the number of co-morbidities. Our primary outcome was incidence and time to first positive SARS-CoV-2 molecular test in the Omicron predominant era. We performed multivariable analyses stratified by calendar time using Cox modeling to determine hazard of SARS-CoV-2. In total, 133,191 patients were analyzed. Having 3+ comorbidities was associated with increased hazard for breakthrough (HR=1.2 CI 1.2-1.6). During the second half of the study, having 2 comorbidities (HR= 1.1 95% CI 1.02-1.2) and having 3+ comorbidities (HR 1.7, 95% CI 1.5-1.9) were associated with increased hazard for Omicron breakthrough. Older age was associated with decreased hazard in the first 6 months of follow-up. Interaction terms for calendar time indicated significant changes in hazard for many factors between the first and second halves of the follow-up period. Conclusions: Omicron breakthrough is common with significantly higher risk for our most vulnerable patients with multiple co-morbidities. Age related behavioral factors play an important role in breakthrough infection with the highest incidence among young adults. Our findings reflect real-world differences in immunity and exposure risk behaviors for populations vulnerable to COVID-19.

Nutritional needs, resources, and barriers among unhoused adults cared for by a street medicine organization in Chicago, Illinois: a cross-sectional study.

BACKGROUND: Those experiencing houselessness rely on obtaining food from community organizers and donations. Simultaneously, the houseless face disproportionally high rates of medical conditions that may be affected by diet including diabetes, hypertension, and hyperlipidemia. There is limited literature on the resources and barriers of the houseless community regarding optimal nutrition from an actionable perspective. Further, less data is available on how street medicine organizations may best impact the nutrition of the unhoused they serve. Elucidating this information will inform how organizational efforts may best support the nutrition of the houseless community. METHODS: In partnership with the medical student-run organization, Chicago Street Medicine, at Northwestern University Feinberg School of Medicine, twenty adults experiencing houselessness in Chicago, Illinois participated in the cross-sectional study. A 10-item survey was verbally administered to characterize the participants' daily food intake, food sources, barriers, resources, and nutritional preferences and needs. All data was directly transcribed into REDCap. Descriptive statistics were generated. RESULTS: Individuals consumed a median of 2 snacks and meals per day (IQR: 1-3). No participant consumed adequate servings of every food group, with only one participant meeting the dietary intake requirements for one food group. Participants most often received their food from donations (n = 15), purchasing themselves (n = 11), food pantries (n = 4), and shelters (n = 3). Eleven of nineteen participants endorsed dental concerns as a major barrier to consuming certain foods. Twelve participants had access to a can opener and twelve could heat their meals on a stove or microwave. Seven had access to kitchen facilities where they may prepare a meal. Approximately half of participants had been counseled by a physician to maintain a particular diet, with most related to reducing sugar intake. CONCLUSION: Most houseless participants were unable to acquire a balanced diet and often relied on organizational efforts to eat. Organizations should consider the chronic health conditions, dentition needs, and physical resources and barriers to optimal nutrition when obtaining food to distribute to the unhoused.

Multidisciplinary providers' perspectives on engaging young black, gay, bisexual and other men who have sex with men living with HIV in mental health care services.

Young Black gay, bisexual, and other men who have sex with men (YB-GBMSM) living with HIV are at high risk for psychological stressors and comorbidities. We sought to gain the perspectives of multidisciplinary providers (including HIV care, mental health care, and social service providers) on their experiences with engaging YB-GBMSM in mental health care within comprehensive HIV primary care centers that included both types of services on-site. We conducted qualitative in-depth interviews with fifteen providers in two clinics, and analyzed the qualitative data using a thematic analysis approach. Our participants described high levels of need for mental health services among YB-GBMSM living with HIV, due to psychological challenges related to living with HIV as well as other frequently occurring life stressors. At the same time, barriers to accessing these services were identified, with mental health stigma, under-recognition of symptoms and confidentiality concerns being the most commonly cited. Strategies to improve mental health service uptake in light of these needs and barriers were discussed, including re-framing of mental health services, addressing logistical barriers, and utilization of a biopsychosocial perspective.

Preferences of Young Black Gay, Bisexual, and Other Men Who Have Sex with Men Regarding Integration of HIV and Mental Health Care Services.

Optimization of mental health service use is critical to HIV care engagement among young Black gay, bisexual, and other men who have sex with men (YB-GBMSM). Clinic-level interventions to integrate HIV and mental health services have been proposed; however, patient perspectives on such care models are often lacking. We conducted a mixed-methods study consisting of surveys (N = 100) and qualitative in-depth interviews (n = 15) with YB-GBMSM recruited from two Ryan White-funded HIV clinics in Atlanta, Georgia. Most participants (70%) agreed that integration of HIV and mental health services was beneficial to them. Thirty-six percent (36%) desired a higher level of integration than what they perceived was currently available in their clinic setting, 51% believed their clinic was already optimally integrated, and 13% preferred less integration. In the qualitative interviews, participants discussed their support for potential integration strategies such as training HIV providers to prescribe antidepressants, closer in-clinic proximity of HIV and mental health providers, and use of patient navigators to help patients access mental health care and remind them of appointments. Perceived benefits of care integration included easier access to mental health services, enhanced overall well-being, and improved HIV care engagement. In summary, YB-GBMSM were supportive of integrating HIV and mental health services, with varying individual preferences regarding the degree and operationalization of this integration. Improving integration of mental health and HIV services, and tailoring modes of service delivery to individual preferences, has the potential to improve both general well-being and HIV care engagement in this high priority population.

Burden and Correlates of Mental Health Symptoms Among Young Black Gay, Bisexual, and Other Men Who Have Sex with Men Engaged in HIV Care in Atlanta.

Mental health comorbidities are prevalent among young Black gay, bisexual, and other men who have sex with men (YB-GBMSM) living with HIV and can adversely impact HIV-related outcomes. We conducted a cross-sectional survey study with 100 YB-GBMSM recruited from two HIV care centers in Atlanta, and constructed multivariable logistic and linear regression models to examine correlates of depression, anxiety, trauma symptoms, and general well-being. In adjusted models, full-time employment was associated with fewer depressive symptoms, while HIV stigma and substance use were associated with higher levels of depressive symptoms. Younger age and full-time employment were negatively associated with severe anxiety, while HIV stigma was positively associated with severe anxiety and trauma symptoms. Trust in physicians, lower HIV stigma, full-time employment, and lack of substance use were associated with higher average general well-being scores. In conclusion, we found high frequency of depressive, anxiety, and trauma-related symptoms among this sample of YB-GBMSM living with HIV. Unemployment, substance use, and HIV stigma emerged as particularly salient correlates of psychological morbidity, suggesting a need for structural and community-level interventions to address mental health in this population.

Exploring influences on methamphetamine use among Black gay, bisexual and other men who have sex with men in Atlanta: A focus group study.

BACKGROUND: Methamphetamine use is a contributor to HIV risk and poor health outcomes among gay, bisexual and other men who have sex with men (GBMSM). There is a paucity of research examining methamphetamine use and its social context specifically among Black GBMSM. We therefore sought to: (1) describe trends in methamphetamine use among Black GBMSM in Atlanta, Georgia, and (2) examine the risk environment (micro-, meso­ and macro-level factors operating in the political, social, physical, economic, and healthcare environments) that might elevate risk for methamphetamine use in this population. METHODS: We conducted a qualitative study consisting of eight focus groups with 54 key informants between December 2019 and March 2020. Participants represented community-based and healthcare organizations that work closely with Black GBMSM. Our thematic analysis included an iterative, team coding approach combining deductive and inductive elements. RESULTS: Participants unanimously agreed that methamphetamine use was increasingly prevalent among Black GBMSM in Atlanta, with many describing a historical arc in which methamphetamine use - previously associated with predominantly white, affluent GBMSM - was now common among younger, lower socioeconomic status Black GBMSM. At the micro-level, participants described contributors to increasing methamphetamine use including use as a sex drug, and the interrelated burdens of stress and mental illness, housing instability, geographic mobility and poverty. At the meso­level, participants described virtual and physical sex scenes including use of geosocial networking apps that facilitated the spread of methamphetamine use in the Black GBMSM community. At the macro-level, participants described how policies prioritizing other concerns (e.g., HIV, opioids) seemed to limit resources available for methamphetamine prevention and treatment programming. CONCLUSION: Multi-level environmental influences are working together to elevate risk for methamphetamine use among Black GBMSM in Atlanta, with potential to adversely impact health and well-being and undermine HIV prevention and treatment efforts.

Mental Health Service Utilization Among Young Black Gay, Bisexual, and Other Men Who Have Sex with Men in HIV Care: A Retrospective Cohort Study.

Young Black gay, bisexual, and other men who have sex with men (YB-GBMSM) face multiple psychosocial stressors, and are disproportionately impacted by HIV. Mental health care engagement is a promising avenue for addressing these disparities. To date, rates of mental health service utilization have not been examined specifically in this population. We conducted a retrospective cohort study among YB-GBMSM receiving care in a Ryan White-funded HIV care center that includes co-located HIV and mental health services. Of 435 unique YB-GBMSM patients, mental health concerns were identified in n = 191 (43.9%). Depressive symptoms were the most common concerns identified, followed by substance use, anxiety, and trauma. Among patients with identified mental health concerns who were not previously in mental health care, 79.1% were referred to mental health care, 56.3% set an appointment with a mental health provider, 40.5% were linked to mental health care (attended an initial visit), and 19.6% remained engaged in mental health care. Younger YB-GBMSM (age 18-24 years), who received care in a more integrated pediatric/adolescent part of the center, were more likely to have an appointment set once a concern was identified (χ2 = 7.17; p = 0.007). Even in a setting with co-located HIV and mental health care services, we found significant gaps in engagement at each stage of a newly described mental health care continuum. Implications for intervention at the provider and systems levels are discussed.
