Household Conflict in the Time of Covid-19
Covid-19 Prevention Behaviors and Mistrust Among Black and Latino Public Housing Residents in NYC
Preventive measures against COVID-19 played a crucial role in mitigating transmission. Social and structural factors influence individuals’ trust in health care and engagement in health-promoting behaviors. This study investigates racial-ethnic differences in COVID-19 prevention behaviors and beliefs among public housing residents in the South Bronx, NYC. Data come from the Nurse-Community-Family Partnership study, a randomized controlled trial c…
Overdose education and naloxone distribution in jails
BACKGROUND: Opioid-related overdose is the leading cause of mortality among individuals recently released from incarceration in the U.S. Naloxone is an FDA-approved opioid antagonist medication designed to rapidly reverse opioid overdose. Despite evidence of its acceptability and effectiveness at reducing the risk of opioid overdose death after release from incarceration, only an estimated 25% of US jails provide naloxone upon release. This study…
A stakeholder-driven framework for measuring potential change in the health risks of people who inject drugs (PWID) during the Covid-19 pandemic
This measurement framework is intended to increase the quality and timeliness of research on the impacts of COVID-19 in the context of the current pandemic and future crises. Next steps include a ranking process to narrow the drivers of change in health risks to a concise set of indicators that adequately represent framework components, can be written as measurable indicators, and are quantifiable using existing data sources, as well as a publicl…

Explaining Racial/Ethnic Dietary Patterns in Relation to Type 2 Diabetes
Racial/ethnic disparities in dietary patterns are present in individuals without T2D, but differences are not statistically significant in those with undiagnosed or diagnosed T2D. Non-Hispanic Blacks without T2D received significantly lower HEI-2010 scores than non-Hispanic Whites. Further research is necessary to determine whether or not similarities in dietary intake across racial/ethnic groups with T2D will be reflected in diabetes-related hea…

Illicit drug use and HIV risk in the Dominican Republic
While the Caribbean has the second highest global human immunodeficiency virus (HIV) prevalence, insufficient attention has been paid to contributing factors of the region's elevated risk. Largely neglected is the potential role of drugs in shaping the Caribbean HIV/acquired immune deficiency syndrome epidemic. Caribbean studies have almost exclusively focused on drug transportation and seldom acknowledged local user economies and drug-related he…

HCV (Hepatitis C Virus) Pre-Test and Post-Test Counseling Services at Drug Treatment Programs
Although drug users are at risk for hepatitis C virus (HCV) infection, many clients in drug treatment programs remain uninformed about their HCV serostatus. Consistent with established Human immunodeficiency virus (HIV) testing and counseling guidelines, recommendations for HCV testing procedures include the delivery of prevention messages targeting all high-risk clients. However, little research has determined whether HCV testing in these progra…
Drug treatment programs' HCV service delivery to their HCV positive clients
Hepatitis C virus (HCV) infection is the most common blood-borne infectious disease among drug users in the US. Drug treatment programs are ideally situated to assist their clients to obtain HCV medical and support services. Using data collected from 233 drug free and methadone maintenance treatment programs (MMTPs) throughout the US, this article examines the range of HCV services that treatment programs provide to their HCV positive clients. Fi…
Staff Perspectives on Facilitating the Implementation of Hepatitis C Services at Drug Treatment Programs
Drug users are at risk of acquiring the hepatitis C virus (HCV). Although ancillary services available to clients at drug treatment programs are often limited, some of these programs are providing HCV services. Presenting qualitative data, the authors describe the HCV education and/or support services available at four drug treatment programs and examine staff and client perspectives on factors that facilitated the implementation of these service…
Increased Access to Unrestricted Pharmacy Sales of Syringes in Seattle–King County, Washington
We examined pharmacists’ attitudes and practices related to syringe sales to injection drug users before and after legal reform and local programming to enhance sterile syringe access. We replicated a 1996 study by conducting pharmacist phone surveys and syringe test-buys in randomly selected pharmacies. Test-buy success increased from 48% in 1996 to 65% in 2003 (P=.04). Pharmacists agreeing that syringes should be available to injection drug use…

Positive deviance control-case life history
We have identified strategies and tactics that some doubly-uninfected IDUs have developed to stay safe. Staying Safe methodology develops grounded hypotheses. These can be tested through cohort studies of incidence and prevention trials of hypothesis-based programs to help drug injectors make their injection and sexual careers safer for themselves and others. This positive deviance control-case life history method might be used to study avoiding …
