ABSTRACT
BACKGROUND: Approximately 7% of all reported tuberculosis (TB) cases each year are recurrent, occurring among people who have had TB in the recent or distant past. TB recurrence is particularly common in India, which has the largest TB burden worldwide. Although patients recently treated for TB are at high risk of developing TB again, evidence around effective active case finding (ACF) strategies in this population is scarce. We will conduct a hybrid type I effectiveness-implementation non-inferiority randomized trial to compare the effectiveness, cost-effectiveness, and feasibility of two ACF strategies among individuals who have completed TB treatment and their household contacts (HHCs). METHODS: We will enroll 1076 adults (≥ 18 years) who have completed TB treatment at a public TB unit (TU) in Pune, India, along with their HHCs (averaging two per patient, n = 2152). Participants will undergo symptom-based ACF by existing healthcare workers (HCWs) at 6-month intervals and will be randomized to either home-based ACF (HACF) or telephonic ACF (TACF). Symptomatic participants will undergo microbiologic testing through the program. Asymptomatic HHCs will be referred for TB preventive treatment (TPT) per national guidelines. The primary outcome is rate per 100 person-years of people diagnosed with new or recurrent TB by study arm, within 12 months following treatment completion. The secondary outcome is proportion of HHCs < 6 years, by study arm, initiated on TPT after ruling out TB disease. Study staff will collect socio-demographic and clinical data to identify risk factors for TB recurrence and will measure post-TB lung impairment. In both arms, an 18-month "mop-up" visit will be conducted to ascertain outcomes. We will use the RE-AIM framework to characterize implementation processes and explore acceptability through in-depth interviews with index patients, HHCs and HCWs (n = 100). Cost-effectiveness will be assessed by calculating the incremental cost per TB case detected within 12 months and projected for disability-adjusted life years averted based on modeled estimates of morbidity, mortality, and time with infectious TB. DISCUSSION: This novel trial will guide India's scale-up of post-treatment ACF and provide an evidence base for designing strategies to detect recurrent and new TB in other high burden settings.

BACKGROUND: Communities of color have been disproportionately impacted by COVID-19. We explored barriers and facilitators to COVID-19 vaccine uptake among African American, Latinx, and African immigrant communities in Washington, DC. METHODS: A total of 76 individuals participated in qualitative interviews and focus groups, and 208 individuals from communities of color participated in an online crowdsourcing contest. RESULTS: Findings documented a lack of sufficient, accurate information about COVID-19 vaccines and questions about the science. African American and African immigrant participants spoke about the deeply rooted historical underpinnings to their community's vaccine hesitancy, citing the prior and ongoing mistreatment of people of color by the medical community. Latinx and African immigrant participants highlighted how limited accessibility played an important role in the slow uptake of COVID-19 vaccines in their communities. Connectedness and solidarity were found to be key assets that can be drawn upon through community-driven responses to address social-structural challenges to COVID-19 related vaccine uptake. CONCLUSIONS: The historic and ongoing socio-economic context and realities of communities of color must be understood and respected to inform community-based health communication messaging to support vaccine equity for COVID-19 and other infectious diseases.
ABSTRACT
Given the need to increase COVID-19 vaccine uptake among US young adults, we examined the extent of COVID-19 vaccine hesitancy in this population and related factors. We analyzed Fall 2020 survey data from 2,453 young adults (ages 18-34) across 6 US metropolitan statistical areas (MSAs; Meanage = 24.67; 55.8% female; 5.4% Black, 12.7% Asian, 11.1% Hispanic; 75.5% college degree or higher). Multivariable linear regression examined correlates of COVID-19 vaccine hesitancy (index score of willingness and likelihood of being vaccinated), including sociopolitical factors (MSA, political orientation, COVID-related news exposure), COVID-19 symptoms and testing, mental health (e.g., COVID-related stress), and sociodemographics. 45.3% were "extremely willing" to get the vaccine (19.8% very, 14.2% somewhat, 3.7% don't know, 7.0% a little, 10.1% not at all); 40.2% were "extremely likely" to get vaccinated (22.1% very, 14.2% somewhat, 5.2% don't know, 7.9% a little, 10.3% not at all). Greater vaccine hesitancy was significantly related to living in specific MSAs (i.e., Atlanta, Oklahoma City, San Diego, Seattle vs. Minneapolis or Boston), identifying as Republican or "no lean" (vs. Democrat), and reporting less COVID-related news exposure and less COVID-related stress, as well as identifying as older, female, Black or other race, having less (vs. greater) than a college education, being married/cohabitating, and having children in the home. Interventions to improve COVID-19 vaccine uptake among hesitant young adults should include communication that address concerns, particularly among women, minority groups, and those from certain geographic regions and/or differing political orientations, and require identifying communication channels that appeal to these groups.
ABSTRACT
BACKGROUND: The COVID-19 pandemic and its associated socioeconomic disruptions have disproportionally affected marginalized populations, including people living with HIV. Little is known about how the pandemic has affected populations experiencing multiple forms of stigma, discrimination, and violence, such as female sex workers (FSW) living with HIV. METHODS: We conducted a cross-sectional survey between August and December 2020 among 187 FSW living with HIV in the Dominican Republic to examine the impact of COVID-19. Using multivariable logistic regression, we examined associations between COVID-19-related financial concerns, mental health, substance use, and partner abuse on engagement in HIV care and antiretroviral therapy adherence. We conducted mediation analysis to assess whether mental health challenges mediated the impact of partner abuse or substance use on HIV outcomes. RESULTS: Most participants reported no income (72%) or a substantial decline in income (25%) since the COVID-19 pandemic. Approximately one-third of the participants (34%) reported COVID-19 had an impact on their HIV care and treatment. Greater COVID-19 financial concerns (adjusted odds ratio [aOR] = 1.14, 95% CI: 1.02 to 1.27), mental health challenges (aOR = 1.38, 95% CI: 1.06 to 1.79), and partner emotional abuse (aOR = 2.62, 95% CI: 1.01 to 6.79) were associated with higher odds of negatively affected HIV care, respectively. The relationship between increased emotional partner abuse and negatively affected HIV care was mediated by greater COVID-19-related mental health challenges. CONCLUSIONS: FSW living with HIV in the Dominican Republic have been significantly affected by the COVID-19 pandemic. Targeted interventions that address structural (financial security and partner abuse) and psychosocial (mental health) factors are needed to sustain HIV outcomes and well-being.
