A qualitative exploration of harm reduction in practice by street-based peer outreach workers.

BACKGROUND: Despite the widespread use of the phrase "harm reduction" and the proliferation of programs based on its principles during the current opioid epidemic, what it means in practice is not universally agreed upon. Harm reduction strategies have expanded from syringe and needle exchange programs that emerged in the mid-1980s primarily in response to the HIV epidemic, to include medication for opioid use disorder, supervised consumption rooms, naloxone distribution, and drug checking technologies such as fentanyl test strips. Harm reduction can often be in tension with abstinence and recovery models to address substance use, and people who use drugs may also hold competing views of what harm reduction means in practice. Street-based outreach workers are increasingly incorporated into harm reduction programs as part of efforts to engage with people more fully in various stages of drug use and nonuse. METHOD: This paper explores how peer outreach workers, called "members," in a street-based naloxone distribution program define and practice harm reduction. We interviewed 15 members of a street-based harm reduction organization in an urban center characterized by an enduring opioid epidemic. Inductive data analysis explored harm reduction as both a set of principles and a set of practices to understand how frontline providers define and enact them. RESULTS: Analysis revealed that when members talked about their work, they often conceptualized harm reduction as a collection of ways members and others can "save lives" and support people who use drugs. They also framed harm reduction as part of a "path toward recovery." This path was complicated and nonlinear but pursued a common goal of life without drug use and its residual effects. These findings suggest the need to develop harm reduction programs that incorporate both harm reduction and recovery to best meet the needs of people who use drugs and align with the value systems of implementers.

Onward transmission of measles virus among vaccinated cases in a large community outbreak in Auckland, New Zealand, 2019.

BACKGROUND: Isolation of cases and quarantining of non-immune contacts are the mainstay of measles outbreak management in elimination settings. Serology testing of exposed contacts may not be feasible in large outbreaks; therefore, vaccination history is used as a proxy for determining immunity to measles and thus prevention of onward virus transmission. This study sought to investigate the risk of measles virus transmission from individuals with a history of one or two doses of measles-containing vaccine (MCV). METHODS:  Retrospective analysis of data from measles cases reported to Auckland Regional Public Health Service during the 2019 Auckland region measles outbreak. Vaccination history was verified using patient records and the New Zealand National Immunisation Register. Onward transmission was determined through case interviews and assessment of exposed contacts. RESULTS:  1451 measles cases were assessed as eligible for vaccination at the time of measles outbreak. Of these, 1015 (70.0%) were unvaccinated, 220 (15.2%) had unknown vaccination status, 139 (9.6%) had received only one dose of MCV and 77 (5.3%) had received two doses of the vaccine. Compared to unvaccinated cases, the odds of onward transmission were lower among those with one dose only (OR 0.41, 95% CI: 0.20-0.75) or two doses of MCV (OR 0.44, 95% CI: 0.17-0.95). Median time since vaccination was longer among those with onward transmission compared to those without onward transmission for one and two doses of the vaccine, suggesting a potential effect of waning immunity among this cohort. CONCLUSION:  These findings support the hypothesis that measles cases with a history of prior vaccination are less likely to transmit the virus to others compared to unvaccinated cases. Such information can be used to support decisions around quarantine requirements for vaccinated contacts in future measles outbreaks.

Augmented Reality in Interventional Radiology: Transforming Training Paradigms.

The ascent of medical technology places augmented reality (AR) at the forefront of potential advancements in interventional radiology (IR) training. This review delves into the symbiotic relationship between AR and conventional IR training, casting light on the opportunities and hurdles intrinsic to this integration. A targeted literature review was conducted using the databases PubMed, Cochrane Library, and Embase. Search terms included ((("Augmented Reality" OR "Virtual Reality")) AND ((Education OR Training))) AND (("Interventional Radiology")). Ten studies identified using the comprehensive inclusion criteria helped scrutinize the use of AR in IR training. Key outcomes include improved procedural accuracy, reduced training duration, and heightened trainee confidence. However, it also identifies limitations such as small sample sizes, reliance on simulation environments, and technological constraints in AR implementation. Despite these challenges, the review underscored the transformative potential of AR in IR education, suggesting its capacity to revolutionize training methodologies. However, it also calls for continued technological development and empirical research to address current challenges and fully leverage AR's capabilities in medical education.

Conflict of interest: the importance of potential.

The UK Medical Research Council (MRC) takes the issue of conflict of interest very seriously. The overall aim is to preserve a climate in which personal and organisational innovation can flourish while ensuring that potential conflicts are disclosed and identified and conflicts are either avoided or managed with integrity. The approach needs to encompass the MRC's various responsibilities and the levels at which conflicts might arise: MRC staff (scientists and administrators); the governing Council; research Boards and committees; external peer-reviewers; and applicants for funding. To achieve its goals, the MRC has issued practical guidance on various aspects of conflict of interest. For the future, the MRC has identified the continuing commercialisation of science and the increasing involvement of lay people in scientific decision-making as special challenges in this area.
