Medication use and mammographic breast density.

Purpose: A dense breast on mammogram is a strong risk factor for breast cancer. Identifying factors that reduce mammographic breast density could thus provide insight into breast cancer prevention. Due to the limited number of studies and conflicting findings, we investigated the associations of medication use (specifically statins, aspirin, and ibuprofen) with mammographic breast density.

Factors Associated With Participation in Rheumatic Disease-Related Research Among Underrepresented Populations: A Qualitative Systematic Review.

Objective: Nonwhite racial/ethnic groups remain underrepresented in rheumatic disease-related research, despite being disproportionately affected by these disorders. Our objective was to systematically review the literature regarding underrepresented patients' perceptions of participation in rheumatic disease research and to develop strategies to improve diversity.

Methods: A systematic search of Embase, PubMed/Medline, PsycINFO, and Cochrane was performed through October 2018.
