Neighborhoods, Networks, and HIV Care Among Men Who Have Sex With Men: Proposal for a Longitudinal Study.

Background: The majority of people living with HIV in the United States are men who have sex with men (MSM), with race- and ethnicity-based disparities in HIV rates and care continuum. In order to uncover the neighborhood- and network-involved pathways that produce HIV care outcome disparities, systematic, theory-based investigation of the specific and intersecting neighborhood and social network characteristics that relate to the HIV care continuum must be engaged.

Objective: Using socioecological and intersectional conceptual frameworks, we aim to identify individual-, neighborhood-, and network-level characteristics associated with HIV care continuum outcomes (viral suppression, retention in care, and antiretroviral adherence) among MSM living with HIV in New York City.

Patterns and Factors Associated With Alcohol Misuse Among Young Black Men Who Have Sex With Men in New York City.

Alcohol misuse is a significant health concern among gay, bisexual, same-gender-loving, and other men who have sex with men (MSM). Yet, little is known about the severity and predictors of alcohol misuse among self-reported young Black MSM. This study aimed to identify patterns of and factors associated with alcohol misuse in a sample of young Black MSM living in New York City.

Demographic differences in the cascade of care for unhealthy alcohol use: A cross-sectional analysis of data from the 2015-2019 National Survey on Drug Use and Health.

Background: The screening, brief intervention, and referral to treatment (SBIRT) model is recommended by the U.S. Preventive Services Task Force to improve recognition of and intervention for unhealthy alcohol use.

Correlates of concordance between self-reported and lab-confirmed viral load among Black and Latine men who have sex with men (BLMSM) living with HIV in New York City.

Sustained viral suppression is one of the four strategies in the U.S. Department of Health and Human Services' (HHS) plan to end the HIV epidemic in the United States.

Dual IL-6 and CTLA-4 blockade regresses pancreatic tumors in a T cell- and CXCR3-dependent manner.

This study aimed to enhance antitumor immune responses to pancreatic cancer via Ab-based blockade of IL-6 and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4). Mice bearing s.c.

Daily cannabis use, cannabis use disorder, and any medical cannabis use among US adults: Associations within racial, ethnic, and sexual minoritized identities in a changing policy context.

Differences in cannabis use patterns among racial, ethnic and sexual minoritized identity subgroups have been attributed to marginalized identity stressors. However, associations at the intersection of these minoritized identities remain underexplored in a changing medical cannabis law (MCL) context. We estimated medical cannabis and daily cannabis use, and cannabis use disorder (CUD) by intersecting racial, ethnic and sexual minoritized identity subgroups.

Medical and Non-Medical Opioid Use at the Intersection of Gender and Sexual Identity: Associations with State Medical Cannabis Law Status in a U.S. National Sample of Adults.

At the structural level, medical cannabis laws (MCLs) have been negatively associated with opioid prescribing practices, and sexual minority adults report disproportionately high non-medical prescription opioid use. We examined medical/non-medical prescription opioid use by intersecting sexual identity and gender and explored associations with MCLs using the 2015-2017 National Survey on Drug Use and Health, which captured sexual identity and MCL state residence for adults 18 + years (N = 126,463). Survey-weighted gender-stratified multinomial logistic models estimated adjusted relative risk ratios (aRRR) of medical vs.

Medical, Nonmedical, and Illegal Stimulant Use by Sexual Identity and Gender.

Introduction: Major knowledge gaps regarding medical and nonmedical prescription stimulant use and illegal stimulant use (i.e., cocaine/crack/methamphetamine) by sexual identity and gender have implications for individuals' health and well-being.

Medical cannabis laws and medical and non-medical prescription stimulant use among a nationally representative sample of US Adults: Examining the role of sexual identity and gender.

Background: Medical marijuana laws (MMLs) can impact marijuana and opioid use, but the relationship between MMLs and other drugs, such as prescription stimulants, remains unexamined. Because lesbian, gay and bisexual (LGB) individuals report higher levels of prescription stimulant use than heterosexuals, we explored the relationship between MMLs and past-year medical and non-medical stimulant use by sexual identity and gender.

Methods: We pooled 2015-2017 National Survey on Drug Use and Health data for adults (n = 126 463), and used survey-weighted multinomial logistic regression to estimate odds of past-year (a) medical prescription stimulant use, (b) non-medical prescription stimulant use and (c) non-medical versus medical stimulant use.

"It's Like Plan B but for HIV!" Design and Evaluation of a Media Campaign to Drive Demand for PEP.

Post-exposure Prophylaxis (PEP) is an effective yet underutilized HIV prevention tool. PEPTALK developed and evaluated a media campaign to drive demand for PEP among men who have sex with men (MSM) and transgender women (TW) living in high HIV prevalence areas in New York City. Formative qualitative research (38 in-depth interviews and five focus groups [N = 48]) with Black or African-American MSM or TW who reported condomless sex with a HIV-positive/unknown status man was conducted to inform campaign design.

SrmB Rescues Trapped Ribosome Assembly Intermediates.

RNA helicases play various roles in ribosome biogenesis depending on the ribosome assembly pathway and stress state of the cell. However, it is unclear how most RNA helicases interact with ribosome assembly intermediates or participate in other cell processes to regulate ribosome assembly. SrmB is a DEAD-box helicase that acts early in the ribosome assembly process, although very little is known about its mechanism of action.

Secure Sharing of mHealth Data Streams through Cryptographically-Enforced Access Control.

Owners of mobile-health apps and devices often want to share their mHealth data with others, such as physicians, therapists, coaches, and caregivers. For privacy reasons, however, they typically want to share a limited subset of their information with each recipient according to their preferences. In this paper, we introduce ShareHealth, a scalable, usable, and practical system that allows mHealth-data owners to specify access-control policies and to cryptographically enforce those policies so that only parties with the proper corresponding permissions are able to decrypt data.

State-level marijuana policies and marijuana use and marijuana use disorder among a nationally representative sample of adults in the United States, 2015-2017: Sexual identity and gender matter.

Background: Research demonstrates an association between state-level medical marijuana laws (MMLs) and increased marijuana use (MU) and MU disorder (MUD) among adults, but has yet to explore this association among lesbian, gay and bisexual (LGB) individuals, including gender differences.

Methods: We pooled the 2015-2017 National Survey on Drug Use and Health data for adults (n = 126,463) and used gender-stratified adjusted multivariable logistic regression to model the odds of past-year MU, past-year medical MU, daily/near-daily MU, and MUD; we also tested the interaction between MML state residence and sexual identity.

Results: Bisexual women had higher past-year MU (40% versus 10.

Using social network analysis to examine alcohol use among adults: A systematic review.

Background: Alcohol use and abuse constitute a major public health problem and identifying their determinants is a priority. Social network analysis can indicate how characteristics of social networks are related to individual health behaviors. A growing number of studies have used social network analysis to examine how social network characteristics influence adult alcohol consumption, but this literature has never been systematically reviewed and summarized.

Impact of a Community-level Intervention on HIV Stigma, Homophobia and HIV Testing in New York City: Results from Project CHHANGE.

Background: HIV stigma and homophobia are barriers to access to HIV prevention and treatment services. Project CHHANGE, Challenge HIV Stigma and Homophobia and Gain Empowerment, was a multicomponent intervention designed to reduce community-level HIV stigma and homophobia via workshops, space-based events and bus shelter ads delivered to community-based organizations and neighborhood residents in a high HIV prevalence, primarily African-American, Black and/or Afro-Caribbean, neighborhood in New York City (NYC).

Methods: Serial cross-sectional, street intercept surveys among residents of the invention neighborhood and matched control neighborhood were conducted before and after the intervention.

Neighborhood and Network Characteristics and the HIV Care Continuum among Gay, Bisexual, and Other Men Who Have Sex with Men.

In order for treatment as prevention to work as a national strategy to contain the HIV/AIDS epidemic in the United States (US), the HIV care continuum must become more robust, retaining more individuals at each step. The majority of people living with HIV/AIDS (PLWHA) in the US are gay, bisexual, and other men who have sex with men (MSM). Within this population, there are distinct race- and ethnicity-based disparities in rates of HIV infection, engagement, and retention in HIV care, and viral suppression.

Medical marijuana laws and adolescent marijuana use in the United States: a systematic review and meta-analysis.

Aims: To conduct a systematic review and meta-analysis of studies in order to estimate the effect of US medical marijuana laws (MMLs) on past-month marijuana use prevalence among adolescents.

Methods: A total of 2999 papers from 17 literature sources were screened systematically. Eleven studies, developed from four ongoing large national surveys, were meta-analyzed.

Preferences for HIV test characteristics among young, Black Men Who Have Sex With Men (MSM) and transgender women: Implications for consistent HIV testing.

Background: Promoting consistent HIV testing is critical among young, Black Men Who Have Sex With Men (MSM) and transgender women who are overrepresented among new HIV cases in the United States. New HIV test options are available, including mobile unit testing, one-minute testing, at home or self-testing and couples HIV testing and counseling (CHTC). In the context of these newer options, the objective of this study was to explore whether and how preferences for specific characteristics of the tests acted as barriers to and/or facilitators of testing in general and consistent testing specifically among young Black MSM and transgender women aged 16 to 29.

Resolvins suppress tumor growth and enhance cancer therapy.

Cancer therapy reduces tumor burden by killing tumor cells, yet it simultaneously creates tumor cell debris that may stimulate inflammation and tumor growth. Thus, conventional cancer therapy is inherently a double-edged sword. In this study, we show that tumor cells killed by chemotherapy or targeted therapy ("tumor cell debris") stimulate primary tumor growth when coinjected with a subthreshold (nontumorigenic) inoculum of tumor cells by triggering macrophage proinflammatory cytokine release after phosphatidylserine exposure.

Neighborhood determinants of mood and anxiety disorders among men who have sex with men in New York City.

Purpose: We examined the relationship between economic, physical, and social characteristics of neighborhoods, where men who have sex with men (MSM) lived and socialized, and symptom scores of depression and generalized anxiety disorder (GAD).

Methods: Participants came from a cross-sectional study of a population-based sample of New York City MSM recruited in 2010-2012 (n = 1126). Archival and survey-based data were obtained on neighborhoods, where the men lived and where they socialized most often.

Developing a community-level anti-HIV/AIDS stigma and homophobia intervention in new York city: The project CHHANGE model.

HIV/AIDS stigma and homophobia are associated with significant negative health and social outcomes among people living with HIV/AIDS (PLWHA) and those at risk of infection. Interventions to decrease HIV stigma have focused on providing information and education, changing attitudes and values, and increasing contact with people living with HIV/AIDS (PLWHA), activities that act to reduce stereotyped beliefs and prejudice, as well as acts of discrimination. Most anti-homophobia interventions have focused on bullying reduction and have been implemented at the secondary and post-secondary education levels.

Associations Among Neighborhood Characteristics and Sexual Risk Behavior Among Black and White MSM Living in a Major Urban Area.

Identifying neighborhood characteristics associated with sexual HIV risk behavior among gay, bisexual and other men who have sex with men (MSM) living in urban areas may inform the development of policies and programs to reduce risk and subsequently HIV prevalence in urban areas. New York City M2M was a cross-sectional study designed to identify neighborhood-level characteristics associated with sexual risk behaviors among MSM living in New York City. This paper presents results of an analysis of neighborhood-level indicators of three distinct social theories of influence of the neighborhood environment on human behavior: physical disorder, social disorganization and social norms theories.
