Effect of neighborhood and individual-level socioeconomic factors on breast cancer screening adherence in a multi-ethnic study.

BACKGROUND: Although mammography can significantly reduce breast cancer mortality, many women do not receive their annual breast cancer screening. Differences in screening adherence exist by race/ethnicity, socioeconomic status (SES), and insurance status. However, more detailed investigations into the impact of neighborhood disadvantage and access to resources on screening adherence are lacking. METHODS: We comprehensively examined the effect of individual social, economic, and demographic factors (n = 34 variables), as well as neighborhood level SES (nSES) indicators (n = 10 variables) on breast cancer screening adherence across a multi-ethnic population (n = 472). In this cross-sectional study, participants were surveyed from 2017 to 2018. The data was analyzed using univariate regression and LASSO for variable reduction. Significant predictors were carried forward into final multivariable mixed-effect logistic regression models where odds ratios (OR), 95% confidence intervals and p-values were reported. RESULTS: Nineteen percent of participants were non-adherent to breast screening guidelines. Race/ethnicity was not associated with adherence; however, increasing age (OR = 0.97, 95%CI = 0.95-0.99, p = 0.01), renting a home (OR = 0.53, 95%CI = 0.30-0.94, p = 0.04), food insecurity (OR 0.46, 95%CI = 0.22-0.94, p = 0.01), and overcrowding (OR = 0.58, 95% CI = 0.32-0.94, p = 0.01) were significantly associated with lower breast cancer screening adherence. CONCLUSION: Socioeconomic indicators at the individual and neighborhood levels impact low breast cancer screening adherence and may help to inform future screening interventions.

'Who is going to put their life on the line for a dollar? That's crazy': community perspectives of financial compensation in clinical research.

BACKGROUND: Financial compensation of research participants has been standard practice for centuries, however, there is an ongoing debate among researchers and ethicists regarding the ethical nature of this practice. While these debates develop ethical arguments and theories, they fail to incorporate input from those most affected by financial compensation: potential research participants. METHODS: To identify attitudes surrounding clinical research, participants of a long-standing cohort completed a one-time interview. Open-ended questions stimulated a participant-driven discussion surrounding medical research. Following a grounded theory methodology, 58 semistructured interview transcripts were coded, focusing on attitudes surrounding financial compensation of research participants. RESULTS: Of the interviews coded, the majority of participants identified as Black/African American (n=44) and were women (n=40). Five major themes emerged. In support of financial compensation, participants felt that study participants should be compensated for time, effort and risk. However, participants were concerned that compensation may differentially impact low-income populations and entice them to hide potentially harmful side effects. Participants also mentioned that financial compensation may invalidate study results if participants knowingly provide false information to subvert inclusion/exclusion criteria. CONCLUSION: The emergence of both positive and negative themes reiterates the complicated issue of providing financial compensation for study participation. While compensation as a motivator for research participation raises ethical concerns, participants discussed weighing the benefits with the risks in order to make an informed decision. To avoid paternalistic behaviours, research staff must allow potential research participants to review the available information and make the decision that best reflects their wishes.

Staphylococcus aureus Nasal Carriage among Beefpacking Workers in a Midwestern United States Slaughterhouse.

Occupational contact with livestock is an established risk factor for exposure to livestock-associated methicillin-resistant Staphylococcus aureus (MRSA), particularly among industrial swine workers. While S. aureus is known to infect cattle, livestock-associated S. aureus carriage among workers in the beef production chain has received limited attention. Beefpacking workers, who slaughter, butcher and process cattle, have intensified exposure to potentially infectious animal materials and may be at risk of livestock-associated S. aureus exposure. We conducted a cross-sectional study of beefpacking workers (n = 137) at an industrial slaughterhouse in the Midwestern United States to evaluate prevalence and characteristics of S. aureus nasal colonization, specifically the absence of the scn gene to identify putative association with livestock, antibiotic susceptibility, presence of Panton-Valentin leukocidin (PVL) genes lukS-PV and lukF-PV, and spa type. Overall prevalence of S. aureus nasal carriage was 27.0%. No workers carried livestock-associated MRSA. Methicillin-sensitive S. aureus isolates (MSSA) recovered from five workers (3.6%) lacked the scn gene and were considered putative livestock-associated S. aureus (pLA-SA). Among pLA-SA isolates, spa types t338, t748, t1476 and t2379 were identified. To our knowledge, these spa types have not previously been identified as associated with livestock. Prevalence of human-adapted MRSA carriage in workers was 3.6%. MRSA isolates were identified as spa types t002, t008 and t024, and four of five MRSA isolates were PVL-positive. To date, this is the first study to indicate that industrial beefpacking workers in the United States may be exposed to livestock-associated S. aureus, notably MSSA, and to spa types not previously identified in livestock and livestock workers. Occupational exposure to livestock-associated S. aureus in the beef production chain requires further epidemiologic investigation.
