Navigation is a multifaceted task, which requires using a combination of strategies and cues from the environment. Navigation can be particularly challenging for individuals with impaired vision, because many informative cues are visual. As mobile computing technology rapidly advances, the range of potential approaches to assist visually impaired people with navigation is also broadening. For computer-based navigational aids, the way in which information is gathered, processed, and presented is key to success and represents a vast space of potential approaches. In an effort to improve understanding and provide guidance on this issue, we present the results of a phone survey about navigational aids from a sample of individuals with impaired vision. The survey assessed the usefulness of existing navigational aids (both low-tech and high-tech) for different aspects of navigation. With an emphasis on indoor wayfinding (orienting oneself and following a route in a building), we also collected responses about specific targets the survey participants search for while navigating, and strategies they commonly use. Our results indicate that indoor wayfinding is a relatively under-supported task during navigation despite rapid advances in technology. These results also provide insights for creating navigational aids that are designed more specifically for the current challenges individuals with impaired vision may experience during this task.

Background: Clinical practice guidelines (CPGs) are moving toward greater consideration of population-level differences, like health inequities, when creating management recommendations. CPGs have the potential to reduce or perpetuate health inequities. The intrinsic design factors of electronic interfaces that contain CPGs are known barriers to guideline use.

Peer support services for people living with HIV (PLHIV) serve varying functions and are a unique resource for support. Peer support programs are considered an important strategy for achieving better quality of life (QoL) for PLHIV and there has been substantial investment in provision of such programs. The present study asks whether being connected to other PLHIV is associated with better QoL for PLHIV in Australia and; whether involvement in formal peer support programs is associated with QoL among people newly diagnosed with HIV.

African, Caribbean, and Black (ACB) women are overrepresented among new HIV diagnoses due to social and structural factors. This study seeks to create, implement, and evaluate a community-based peer-led intervention to improve access to HIV prevention and care for ACB women in Canada. This multisite, five-year project, using community-based participatory research, implementation science and evaluation frameworks, will be implemented in five non-iterative phases.

Background: Many transgender women with HIV achieve suboptimal advancement through the HIV Care Continuum, including poor HIV health care usage, retention in HIV medical care, and rates of viral suppression. These issues are exacerbated by comorbid conditions, such as substance use disorder, which is also associated with reduced quality of life, increased overdose deaths, usage of high-cost health care services, engagement in a street economy, and cycles of incarceration. Thus, it is critical that efforts to End the HIV Epidemic include effective interventions to link and retain transgender women in HIV care through full viral suppression.
