Naloxone protection, social support, network characteristics, and overdose experiences among a cohort of people who use illicit opioids in New York City
Bennett, Alex S; Scheidell, Joy; Bowles, Jeanette M; Khan, Maria; Roth, Alexis; Hoff, Lee; Marini, Christina; Elliott, Luther
BACKGROUND:Despite increased availability of take-home naloxone, many people who use opioids do so in unprotected contexts, with no other person who might administer naloxone present, increasing the likelihood that an overdose will result in death. Thus, there is a social nature to being "protected" from overdose mortality, which highlights the importance of identifying background factors that promote access to protective social networks among people who use opioids. METHODS:We used respondent-driven sampling to recruit adults residing in New York City who reported recent (past 3-day) nonmedical opioid use (n = 575). Participants completed a baseline assessment that included past 30-day measures of substance use, overdose experiences, and number of "protected" opioid use events, defined as involving naloxone and the presence of another person who could administer it, as well as measures of network characteristics and social support. We used modified Poisson regression with robust variance to estimate unadjusted and adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs). RESULTS:66% of participants had ever been trained to administer naloxone, 18% had used it in the past three months, and 32% had experienced a recent overdose (past 30 days). During recent opioid use events, 64% reported never having naloxone and a person to administer present. This was more common among those: aged ≥ 50 years (PR: 1.18 (CI 1.03, 1.34); who identified as non-Hispanic Black (PR: 1.27 (CI 1.05, 1.53); experienced higher levels of stigma consciousness (PR: 1.13 (CI 1.00, 1.28); and with small social networks (< 5 persons) (APR: 1.14 (CI 0.98, 1.31). Having a recent overdose experience was associated with severe opioid use disorder (PR: 2.45 (CI 1.49, 4.04), suicidality (PR: 1.72 (CI 1.19, 2.49), depression (PR: 1.54 (CI 1.20, 1.98) and positive urinalysis result for benzodiazepines (PR: 1.56 (CI 1.23, 1.96), but not with network size. CONCLUSIONS:Results show considerable gaps in naloxone protection among people who use opioids, with more vulnerable and historically disadvantaged subpopulations less likely to be protected. Larger social networks of people who use opioids may be an important resource to curtail overdose mortality, but more effort is needed to harness the protective aspects of social networks.

The stigma system: How sociopolitical domination, scapegoating, and stigma shape public health
Friedman, Samuel R; Williams, Leslie D; Guarino, Honoria; Mateu-Gelabert, Pedro; Krawczyk, Noa; Hamilton, Leah; Walters, Suzan M; Ezell, Jerel M; Khan, Maria; Di Iorio, Jorgelina; Yang, Lawrence H; Earnshaw, Valerie A
Stigma is a fundamental driver of adverse health outcomes. Although stigma is often studied at the individual level to focus on how stigma influences the mental and physical health of the stigmatized, considerable research has shown that stigma is multilevel and structural. This paper proposes a theoretical approach that synthesizes the literature on stigma with the literature on scapegoating and divide-and-rule as strategies that the wealthy and powerful use to maintain their power and wealth; the literatures on racial, gender, and other subordination; the literature on ideology and organization in sociopolitical systems; and the literature on resistance and rebellion against stigma, oppression and other forms of subordination. we develop a model of the "stigma system" as a dialectic of interacting and conflicting structures and processes. Understanding this system can help public health reorient stigma interventions to address the sources of stigma as well as the individual problems that stigma creates. On a broader level, this model can help those opposing stigma and its effects to develop alliances and strategies with which to oppose stigma and the processes that create it.

Integrating Screening and Treatment of Unhealthy Alcohol Use and Depression with Screening and Treatment of Anxiety, Pain, and Other Substance Use Among People with HIV and Other High-Risk Persons
Caniglia, Ellen C; Khan, Maria; Ban, Kaoon; Braithwaite, R Scott
We review and synthesize results from a series of analyses estimating the benefit of screening for unhealthy alcohol use, depression, and tobacco to detect individuals at heightened risk for co-occurring anxiety, pain, depression, unhealthy alcohol use, and other substance use among people with HIV and HIV-uninfected individuals in the Veterans Aging Cohort Study. We also examine the potential impact of reducing unhealthy alcohol use and depressive symptoms on the incidence of co-occurring conditions. We found that screening for alcohol and depression may help identify co-occurring symptoms of anxiety, depression, and pain interference, treating unhealthy alcohol use may improve co-occurring pain interference and substance use, and improving depressive symptoms may improve co-occurring anxiety, pain interference, and smoking. We propose that an integrated approach to screening and treatment for unhealthy alcohol use, depression, anxiety, pain, and other substance use may facilitate diagnostic assessment and treatment of these conditions, improving morbidity and mortality.

HIV Diagnosis and the Clinical Course of COVID-19 Among Patients Seeking Care Within the New York City Public Hospital System During the Initial Pandemic Peak
Kaplan-Lewis, Emma; Banga, Jaspreet; Khan, Maria; Casey, Eunice; Mazumdar, Medha; Bratu, Simona; Abdallah, Marie; Pitts, Robert; Leider, Jason; Hennessey, Karen; Cohen, Gabriel M; Cleland, Charles M; Salama, Carlos
Reports conflict on how HIV infection influences the clinical course of COVID-19. The New York City (NYC) public hospital system provides care for over 14,000 people with HIV, was central in responding to the COVID-19 pandemic, and is therefore in a unique position to evaluate the intersection of these concurrent infections. Retrospective chart review of patients presenting to NYC Health and Hospitals (NYC H+H) diagnosed with COVID-19 infection from March 1, 2020, through April 28, 2020, compared people living with HIV (PLWH) and a propensity-matched (PM) control group of patients without HIV to evaluate associations between HIV status and COVID-19 outcomes. Two hundred thirty-four PLWH presented for COVID-19 testing and 110 (47%) were diagnosed with COVID-19. Among 17,413 patients with COVID-19 and without HIV, 1:n nearest neighbor propensity score matching identified 194 patients matched on age, sex, race, and any comorbidity. In the sample with COVID-19 (N = 304), PLWH (9.1%) had lower rates of mortality than controls [19.1%; PM odds ratio (PM-OR): 0.41, 95% confidence interval (CI): 0.19-0.86]. Among hospitalized COVID-19 patients (N = 179), HIV infection was associated with lower rates of mechanical ventilation (PM-OR: 0.31, 95% CI: 0.11-0.84) and mortality (PM-OR: 0.40, 95% CI: 0. 17-0.95). In the extended pandemic period through April 2021, aggregate data by HIV status suggested elevated hospitalization and mortality rates in PLWH versus people without HIV. These results suggest that the direct biological impacts of the HIV virus do not negatively influence COVID-19-related outcomes when controlling for comorbidity and demographic variables.

Pre-Exposure Prophylaxis (PrEP) Awareness Among Black Men Who Have Sex with Men with a History of Criminal Justice Involvement in Six U.S. Cities: Findings from the HPTN 061 Study
Feelemyer, Jonathan P; Khan, Maria R; Dyer, Typhanye V; Turpin, Rodman E; Hucks-Ortiz, Christopher; Cleland, Charles M; Scheidell, Joy D; Hoff, Lee; Mayer, Kenneth H; Brewer, Russell A
Transition from detention to the community for Black men who have sex with men with criminal justice involvement (BMSM-CJI) represents a particularly vulnerable period for HIV acquisition and transmission. We examined levels of HIV PrEP awareness among BMSM-CJI. PrEP awareness among BMSM-CJI was low (7.9%) with evidence of lower awareness levels among those with STI. There was evidence that HIV testing history was associated with higher PrEP awareness. Study findings highlight needs for further assessment of PrEP knowledge among BMSM-CJI. The strong association between HIV testing and PrEP awareness underscores an opportunity to integrate PrEP education within HIV/STI testing services.

Characterisation of social support following incarceration among black sexual minority men and transgender women in the HPTN 061 cohort study
Scheidell, Joy D; Dyer, Typhanye V; Hucks-Ortiz, Christopher; Abrams, Jasmyn; Mazumdar, Medha; Cleland, Charles; Irvine, Natalia; Turpin, Rodman E; Severe, MacRegga; Mayer, Kenneth; Khan, Maria
OBJECTIVE:To examine longitudinal associations between recent incarceration and subsequent social support among black sexual minority men and transgender women, and whether associations differed between those who did and did not have support prior to incarceration. DESIGN:A secondary analysis in 2020 of data from the HIV Prevention Trials Network 061, a cohort study of black sexual minority men and transgender women recruited in 2009-2010 and followed for 12 months. SETTING:Six US cities (Atlanta, Boston, Los Angeles, New York City, San Francisco and Washington DC). PARTICIPANTS:Individuals ≥18 years of age who identified as black, reported being male or assigned male at birth, reported ≥1 unprotected anal intercourse event with a male partner in the past 6 months, and reported on incarceration at the 6-month follow-up visit. EXPOSURE:Having spent ≥1 night in jail/prison in the past 6 months reported at the 6-month follow-up visit. OUTCOME:Social support measured using a six-item scale assessing frequency of emotional/informational, affectionate and tangible support (range 6-30); and dichotomous indicators of low support for each item (ie, receiving that form of support none/little of the time). RESULTS:Among participants who returned for the 6-month visit (N=1169), 14% had experienced incarceration in the past 6 months. Mean support score was 20.9; 18.9 among those with recent incarceration versus 21.2 among those without. Recent incarceration predicted lower support (adjusted β -2.40, 95% CI -3.94 to -0.85). Those recently incarcerated had increased risk of lacking emotional/informational (eg, no one to talk to adjusted risk ratio (aRR) 1.55, 95% CI 1.13 to 2.13) and affectionate (aRR 1.51, 95% CI 1.11 to 2.04) but not tangible support. Effects appeared somewhat stronger among those who had support at baseline. CONCLUSIONS:Incarceration may reduce support on re-entry among black sexual minority men and transgender women, populations unequally targeted for incarceration and at risk for low support.

Association of substance use disorders and drug overdose with adverse COVID-19 outcomes in New York City: January-October 2020
Allen, Bennett; El Shahawy, Omar; Rogers, Erin S; Hochman, Sarah; Khan, Maria R; Krawczyk, Noa
BACKGROUND:Evidence suggests that individuals with history of substance use disorder (SUD) are at increased risk of COVID-19, but little is known about relationships between SUDs, overdose and COVID-19 severity and mortality. This study investigated risks of severe COVID-19 among patients with SUDs. METHODS:We conducted a retrospective review of data from a hospital system in New York City. Patient records from 1 January to 26 October 2020 were included. We assessed positive COVID-19 tests, hospitalizations, intensive care unit (ICU) admissions and death. Descriptive statistics and bivariable analyses compared the prevalence of COVID-19 by baseline characteristics. Logistic regression estimated unadjusted and sex-, age-, race- and comorbidity-adjusted odds ratios (AORs) for associations between SUD history, overdose history and outcomes. RESULTS:Of patients tested for COVID-19 (n = 188 653), 2.7% (n = 5107) had any history of SUD. Associations with hospitalization [AORs (95% confidence interval)] ranged from 1.78 (0.85-3.74) for cocaine use disorder (COUD) to 6.68 (4.33-10.33) for alcohol use disorder. Associations with ICU admission ranged from 0.57 (0.17-1.93) for COUD to 5.00 (3.02-8.30) for overdose. Associations with death ranged from 0.64 (0.14-2.84) for COUD to 3.03 (1.70-5.43) for overdose. DISCUSSION/CONCLUSIONS:Patients with histories of SUD and drug overdose may be at elevated risk of adverse COVID-19 outcomes.

Brief original report: Does smoking status provide information relevant to screening for other substance use among US adults?
Khan, Maria R; Ban, Kaoon; Caniglia, Ellen C; Edelman, Jennifer E; Gaither, Julie; Crystal, Stephen; Chichetto, Natalie E; Young, Kailyn E; Tate, Janet; Justice, Amy C; Braithwaite, R Scott
We assessed whether tobacco screening provides clinically meaningful information about other substance use, including alcohol and other drug use, potentially facilitating targeting of screening for substance use. Using data from the Veterans Aging Cohort Study survey sample (VACS; NÂ =Â 7510), we calculated test performance characteristics of tobacco use screening results for identification of other substance use including sensitivity, specificity, positive-likelihood-ratio (+LRÂ =Â [sensitivity/(1-specificity)]: increase in odds of substance use informed by a positive tobacco screen), and negative-likelihood-ratio (-LR: [(1-sensitivity)/specificity]: reduction in odds of substance use informed by a negative tobacco screen). The sample was 95% male, 75% minority, and 43% were current and 33% were former smokers. Never smoking, versus any history, indicated an approximate four-fold decrease in the odds of injection drug use (-LRÂ =Â 0.26), an approximate 2.5-fold decrease in crack/cocaine (-LRÂ =Â 0.35) and unhealthy alcohol use (-LRÂ =Â 0.40), an approximate two-fold decrease in marijuana (-LRÂ =Â 0.51) and illicit opioid use (-LRÂ =Â 0.48), and an approximate 30% decrease in non-crack/cocaine stimulant use (-LRÂ =Â 0.75). Never smoking yielded more information than current non-smoking (never/former smoking). Positive results on tobacco screening were less informative than negative results; current smoking, versus former/never smoking, provided more information than lifetime smoking and was associated with a 40% increase in the odds of non-crack/cocaine stimulant use (+LRÂ =Â 1.40) and opioid use (+LRÂ =Â 1.44), 50% increase in marijuana use (+LRÂ =Â 1.52) and injection drug use (+LRÂ =Â 1.55), and an 80-90% increase in crack/cocaine use (+LRÂ =Â 1.93) and unhealthy alcohol use (+LRÂ =Â 1.75). When comprehensive screening for substance use is not possible, tobacco screening may inform decisions about targeting substance use screening.
