Distinguishing benign and malignant myxoid soft tissue tumors: Performance of radiomics vs. radiologists.

Introduction: Benign and malignant myxoid soft tissue tumors have shared clinical, imaging, and histologic features that can make diagnosis challenging. The purpose of this study is comparison of the diagnostic performance of a radiomic based machine learning (ML) model to musculoskeletal radiologists.

Methods: Manual segmentation of 90 myxoid soft tissue tumors (45 myxomas and 45 myxofibrosarcomas) was performed on axial T1, and T2FS or STIR magnetic resonance imaging sequences.

Health and well-being needs of Indigenous adolescents: a protocol for a scoping review of qualitative studies.

Introduction: Improving the health of Indigenous adolescents is central to addressing the health inequities faced by Indigenous peoples. To achieve this, it is critical to understand what is needed from the perspectives of Indigenous adolescents themselves. There have been many qualitative studies that capture the perspectives of Indigenous young people, but synthesis of these has been limited to date.

In search of respect and continuity of care: Hungarian women's experiences with midwifery-led, community birth.

Introduction: To describe and compare intervention rates and experiences of respectful care when Hungarian women opt to give birth in the community.

Methods: We conducted a cross-sectional online survey (N = 1257) in 2014. We calculated descriptive statistics comparing obstetric procedure rates, respectful care indicators, and autonomy (MADM scale) across four models of care (public insurance; chosen doctor or chosen midwife in the public system; private midwife-led community birth).

It's all about connection: Determinants of social support and the influence on HIV treatment interruptions among people living with HIV in British Columbia, Canada.

Background: Social support has previously been found to be associated with improved health outcomes of individuals managing chronic illnesses, including amongst people living with HIV (PLWH). For women and people who use injection drugs who continue to experience treatment disparities in comparison to other PLWH, social support may have potential in facilitating better treatment engagement and retention. In this analysis, we examined determinants of social support as measured by the Medical Outcomes Study - Social Support Survey (MOS-SSS) scale, and quantified the relationship between MOS-SSS and HIV treatment interruptions (TIs) among PLWH in British Columbia, Canada.

Structural racism and violence: Routine healthcare access in a cohort of marginalized Indigenous women and Two-Spirit Peoples during the COVID-19 Pandemic.

Objectives: Historical and ongoing colonial violence, racism, discrimination, criminalization, and intergenerational trauma continues to impact the health of Indigenous women (cisgender and transgender) and Two-Spirit Peoples. Previous and ongoing work clearly articulate the deeply harmful roles of colonialism and racism in continuing to systemically exclude Indigenous Peoples from accessing equitable and culturally safe healthcare. While the COVID-19 pandemic has amplified structural inequities, little attention has been paid to how the pandemic impacts healthcare access for Indigenous women and Two-Spirit Peoples living in urban settings.

"They Give you a bus Ticket and They Kick you Loose": A Qualitative Analysis of Post-Release Experiences among Recently Incarcerated Women Living with HIV in Metro Vancouver, Canada.

To explore the transition from correctional facilities to community among women living with HIV in Vancouver, Canada, we interviewed 19 recently incarcerated women and 6 service providers. Findings highlighted heightened risk of violence at release, a lack of immediate supports, challenges accessing safe housing and addictions treatment, and interruptions in HIV treatment and care. In the face of structural barriers, women blamed themselves for not being able to break the cycle of incarceration.

A qualitative exploration of Indigenous patients' experiences of racism and perspectives on improving cultural safety within health care.

Background: In Canada, Indigenous Peoples continue to experience persistent health inequities, resulting in disproportionately poorer health outcomes compared with non-Indigenous Canadians. This study engaged Indigenous patients accessing health care in Vancouver, Canada, about their experiences of racism and improving cultural safety within health care.

Methods: A research team consisting of Indigenous and non-Indigenous researchers committed to employing a Two-Eyed Seeing approach and conducting culturally safe research hosted 2 sharing circles in May 2019 with Indigenous people recruited from urban health care settings.

Prevalence and structural correlates of HIV and STI testing among a community-based cohort of women sex workers in Vancouver Canada.

Background: In light of the stark inequities in HIV and sexually transmitted infections (STIs) experienced by women sex workers, empirical evidence is needed to inform accessible and sex worker-friendly models of voluntary, confidential and non-coercive HIV and STI testing. We evaluated the prevalence and structural correlates of HIV/STI testing in the last 6 months in a large, community-based cohort of women sex workers in Vancouver, Canada.

Methods: Data were drawn from an open community-based open cohort of women sex workers (January 2010-August 2021) working across diverse street, indoor, and online environments in Vancouver, Canada.

Interest in using buprenorphine-naloxone among a prospective cohort of street-involved young people in Vancouver, Canada.

Introduction: Limited research examines buprenorphine-naloxone interest among adolescents and young adults (AYA). This longitudinal study examined factors associated with initial buprenorphine-naloxone interest and the time to a positive change in buprenorphine-naloxone interest or enrollment, in addition to identifying reasons for buprenorphine-naloxone disinterest.

Methods: The study derived data from a cohort of street-involved AYA in Vancouver, Canada between December 2014 and June 2018.

Interest in receiving psychedelic-assisted therapy among marginalized women: Implications and findings from a community-based study in Canada.

Background: Psychedelic-assisted therapies are receiving mounting attention for their therapeutic potential. However, little is known about interest among women who experience elevated risk of mental health and substance use disorders. This study examined interest in receiving psychedelic-assisted therapy and socio-structural factors associated with interest among marginalized women.

Prevalence and Social-Structural Correlates of Gender-Based Violence Against Women Living With HIV in Metro Vancouver, Canada.

Violence experienced by cisgender (cis) and gender minority women living with HIV is known to be high. More work is needed to better understand how to support women living with HIV who have experienced violence. The objectives of this study are therefore to identify the prevalence and correlates of violence by any perpetrator among women living with HIV in a Canadian setting.

BARRIERS TO GOVERNMENTAL INCOME SUPPORTS FOR SEX WORKERS DURING COVID-19: RESULTS OF A COMMUNITY-BASED COHORT IN METRO VANCOUVER.

The COVID-19 pandemic has brought into stark focus the economic inequities faced by precarious, criminalized and racialized workers. Sex workers have been historically excluded from structural supports due to criminalization and occupational stigma. Given emerging concerns regarding sex workers' inequitable access to COVID-19 income supports in Canada and elsewhere, our objective was to identify prevalence and correlates of accessing emergency income supports among women sex workers in Vancouver, Canada.

Violence, policing, and systemic racism as structural barriers to substance use treatment amongst women sex workers who use drugs: Findings of a community-based cohort in Vancouver, Canada (2010-2019).

Background: Despite a high prevalence of substance use among women sex workers (SWs), rigorous social epidemiologic data on substance use treatment experiences among SWs remains limited. Given these gaps and the disproportionate burden of criminalization borne by Indigenous SWs, we evaluated (1) structural correlates of unsuccessful attempts to access substance use treatment; and (2) the interaction between policing and Indigenous ancestry on unsuccessful attempts to access treatment among SWs who use drugs.

Methods: Prospective data were from an open community-based cohort of women SWs (2010-2019) in Vancouver, Canada.

Estimating the Practice-Level and National Cost Burden of Treatment-Related Prior Authorization for Academic Radiation Oncology Practices.

Purpose: Prior authorization (PA) imposes significant time burdens on radiation oncology practices, but its financial impact has not been characterized. We used time-driven activity-based costing (TDABC) to assess the cost burden of treatment-related PA events at an academic radiation oncology practice. We then estimated annual costs for an academic practice and academic practices nationally.

Frequency, topic, and preferences: Tracking student engagement with several modalities of student-instructor contact in a first-year course.

Meaningful student-instructor interactions during an undergraduate degree course can have important effects on student learning. The format by which those interactions are made possible can vary greatly. We investigated the preferred modality of contact and students' reasons for contact across several modalities in a first-year biology course.

Physics-Based Modelling and Simulation of Multibeam Echosounder Perception for Autonomous Underwater Manipulation.

One of the key distinguishing aspects of underwater manipulation tasks is the perception challenges of the ocean environment, including turbidity, backscatter, and lighting effects. Consequently, underwater perception often relies on sonar-based measurements to estimate the vehicle's state and surroundings, either standalone or in concert with other sensing modalities, to support the perception necessary to plan and control manipulation tasks. Simulation of the multibeam echosounder, while not a substitute for in-water testing, is a critical capability for developing manipulation strategies in the complex and variable ocean environment.

Health consequences of child removal among Indigenous and non-Indigenous sex workers: Examining trajectories, mechanisms and resiliencies.

The child protection system can be a highly consequential institution for mothers who are sex workers, yet scant attention has been paid to the health consequences of its policies on this population. Drawing on 31 in-depth, semi-structured interviews with 19 Indigenous and 12 non-Indigenous sex workers in Vancouver, Canada, and using the stress process model and the concept of slow violence, this study proposes a typology of four trajectories through which child removal by this system shaped sex workers' health. Results suggest that child removal has health consequences beyond the conventionally thought of mechanism of mental distress and related health sequelae, to additionally alter women's social conditions, which also carried risks for health.

Ancient DNA analysis of archaeological specimens extends Chinook salmon's known historic range to San Francisco Bay's tributaries and southernmost watershed.

Understanding a species' historic range guides contemporary management and habitat restoration. Chinook salmon (Oncorhynchus tshawytscha) are an important commercial and recreational gamefish, but nine Chinook subspecies are federally threatened or endangered due to anthropogenic impacts. Several San Francisco Bay Area streams and rivers currently host spawning Chinook populations, but government agencies consider these non-native hatchery strays.

Underreporting of Violence to Police among Women Sex Workers in Canada: Amplified Inequities for Im/migrant and In-Call Workers Prior to and Following End-Demand Legislation.

Sex workers globally face high levels of violence. In Canada, im/migrant sex workers who work in indoor venues may be uniquely targeted by police due to immigration policies, racialized policing, and the conflation of trafficking and sex work. In 2014, Canada passed end-demand legislation that purportedly encourages sex workers to report violence to police; however, little research has evaluated its impact.

Overdose among mothers: The association between child removal and unintentional drug overdose in a longitudinal cohort of marginalised women in Canada.

Background: Accidental overdose is a major public health concern in North America with research primarily focused on cisgender men. Little is known about the burden of overdose among marginalised women, particularly in the context of child custody loss. This study aims to examine the prevalence of overdose and the association with child removal in a cohort of marginalised women.

Radiation Therapy Adherence Among Patients Experiencing Homelessness.

Purpose: Radiation therapy is a valuable, yet time- and resource-intense therapy. Patients experiencing homelessness (PEH) face many barriers related to the timely receipt of radiation therapy. Owing to a paucity of data regarding cancer treatment and homelessness, clinicians have a limited evidence base when recommending therapy to PEH.

Ancient Beringian paleodiets revealed through multiproxy stable isotope analyses.

The earliest Native Americans have often been portrayed as either megafaunal specialists or generalist foragers, but this debate cannot be resolved by studying the faunal record alone. Stable isotope analysis directly reveals the foods consumed by individuals. We present multi-tissue isotope analyses of two Ancient Beringian infants from the Upward Sun River site (USR), Alaska (~11,500 years ago).

Subduing the influence of PCR inhibitors on amplifying aged, degraded, and low copy number DNA: PCR enhancer cocktail-p and rescue PCR.

PCR inhibitors are a formidable problem to the study of aged, degraded, and/or low copy number DNA. As a result, there is a need to find alternate methods that ameliorate the efficacy of PCR. In this study, we attempted to use genetic methods to identify the species of salmonid (Oncorhynchus spp.
