Street-involved youth who use drugs (YWUD) face an elevated risk of HIV acquisition and represent a key population for HIV prevention initiatives, including pre-exposure prophylaxis (PrEP). However, little is known regarding the acceptability and feasibility of PrEP uptake and adherence among this multiply-marginalized population. Semi-structured qualitative interviews were conducted with 24 street-involved YWUD (ages 17-24) to examine their perspectives toward PrEP; youth were recruited through a longitudinal prospective cohort study in Vancouver, Canada. Youth reported high levels of ambivalence toward PrEP despite engagement in HIV-related risk behaviors. This ambivalence was driven by misperceptions regarding HIV transmission, including stigmatizing associations between HIV transmission and personal hygiene. Such misperceptions led participants to enact strategies that were ineffective in preventing HIV transmission. Participants contested their inclusion as a "key population" for PrEP, which limited their enthusiasm for PrEP uptake and adherence. Participants also highlighted that wider social-structural inequities (e.g., housing vulnerability, poverty) that produced HIV-related risks were likely to undermine sustained PrEP use. Findings demonstrate the need for tailored implementation strategies to increase PrEP acceptability, including targeted education and anti-stigma interventions to increase awareness about HIV transmission. Interventions should also target structural inequities in order to fully address HIV risk and PrEP ambivalence.

NUT carcinoma is a rare, aggressive cancer defined by rearrangements of the NUTM1 gene. No routinely effective treatments of NUT carcinoma exist, despite harboring a targetable oncoprotein, most commonly BRD4-NUT. The vast majority of cases are fatal. Poor awareness of the disease is a major obstacle to progress in the treatment of NUT carcinoma. While the incidence likely exceeds that of Ewing sarcoma, and BRD4-NUT heralded the bromodomain and extra-terminal domain (BET) inhibitor class of selective epigenetic modulators, NUT carcinoma is incorrectly perceived as "impossibly rare," and therefore receives comparatively little private or governmental funding or prioritization by pharma. To raise awareness, propagate scientific knowledge, and initiate a consensus on standard and targeted treatment of NUT carcinoma, we held the First International Symposium on NUT Carcinoma on March 3, 2021. This virtual event had more than eighty attendees from the Americas, Europe, Asia, and Australia. Patients with NUT carcinoma and family members were represented and shared perspectives. Broadly, the four areas discussed by experts in the field included (1) the biology of NUT carcinoma; (2) standard approaches to the treatment of NUT carcinoma; (3) results of clinical trials using BET inhibitors; and (4) future directions, including novel BET bromodomain inhibitors, combinatorial approaches, and immunotherapy. It was concluded that standard chemotherapeutic approaches and first-generation BET bromodomain inhibitors, the latter complicated by a narrow therapeutic window, are only modestly effective in a minority of cases. Nonetheless, emerging second-generation targeted inhibitors, novel rational synergistic combinations, and the incorporation of immuno-oncology approaches hold promise to improve the prognosis of this disease.
