Background: People who use substances (PWUS) encounter significant barriers to accessing care for their complex health needs. As a result, emergency departments (EDs) often become the first point of healthcare access for many PWUS and are a crucial setting for the study of health inequities. This study aimed to understand the ED healthcare experiences of PWUS with the intent of informing ways of improving the delivery of equitable care. Methods: This qualitative study was part of a larger cross-sectional, mixed-methods study that examined ED experiences among diverse underserved and equity-deserving groups (EDGs) within Kingston, Ontario, Canada. Participants shared and self-interpreted a story about a memorable ED or UCC visit within the preceding 24 months. Data from participants who self-identified as having substance use experiences was analyzed through inductive thematic analysis. Results: Of the 1973 unique participants who completed the survey, 246 participants self-identified as PWUS and were included in the analysis. Most participants were < 45 years of age (61%), male (53%), and white/European (57%). 45% identified as a person with a disability and 39% frequently struggled to make ends meet. Themes were determined at the patient, provider, and system levels. Patient: history of substance use and experience of intersectionality negatively influenced participants' anticipation and perception of care. Provider: negative experiences were linked to assumption making, feelings of stigma and discrimination, and negative perceptions of provider care. Whereas positive experiences were linked to positive perceptions of provider care. System: timeliness of care and the perception of inadequate mental health resources negatively impacted participants' care experience. Overall, these themes shaped participants' trust of ED staff, their desire to seek care, and their perception of the care quality received. Conclusions: PWUS face significant challenges when seeking care in the ED. Given that EDs are a main site of healthcare utilization, there is an urgent need to better support staff in the ED to improve care experiences among PWUS. Based on the findings, three recommendations are proposed: (1) Integration of an equity-oriented approach into the ED, (2) Widespread training on substance use, and (3) Investment in expert resources and services to support PWUS.

Background: Evidence exists showing that various aspects of diet are implicated in the etiology of prostate cancer, although results across studies remain inconsistent. Methods: We examined the ability of the dietary inflammatory index (DII) to predict prostate cancer in a case-control study conducted in Kingston, Ontario, Canada, between 1997 and 1999. The study included 72 cases of incident primary prostate cancer patients and 302 controls of urology clinic patients who had prostate conditions other than prostate cancer. The DII was computed based on intake of 18 nutrients assessed using a 67-item food frequency questionnaire. Univariate and multivariate logistic regression models were used to estimate odds ratios (ORs). Results: Men with higher DII scores were at increased risk of prostate cancer using DII score fit both as a continuous [OR = 1.58, 95% confidence interval (CI) 1.05–2.38] and categorical variable [compared to men in the lowest DII quartile, men in the highest quartile were at elevated risk (OR = 3.50, 95% CI 1.25–9.80; ptrend = 0.02)]. There was no significant heterogeneity by weight status, but stronger association was observed in men with body mass index >25 kg/m2 versus <25 kg/m2. Conclusion: These findings suggest that a proinflammatory diet, as indicated by increasing DII score, is a risk factor for prostate cancer. [ABSTRACT FROM AUTHOR]
