Advancing Inclusive Research: Establishing Collaborative Strategies to Improve Diversity in Clinical Trials.

Well-characterized disparities in clinical research have disproportionately affected patients of color, particularly in underserved communities. To tackle these barriers, Genentech formed the External Council for Advancing Inclusive Research, a 14-person committee dedicated to developing strategies to increase clinical research participation. To help improve the recruitment and retention of patients of color, this article chronicles our efforts to tangibly address the clinical research barriers at the system, study, and patient levels over the last four years. These efforts are one of the initial steps to fully realize the promise of personalized health care and provide increased patient benefit at less cost to society. Instead of simply acknowledging the problem, here we illuminate the collaborative and multilevel strategies that have been effective in delivering meaningful progress for patients.

Preliminary Efficacy of a Recruitment Educational Strategy on Alzheimer's Disease Knowledge, Research Participation Attitudes, and Enrollment Among Hispanics.

INTRODUCTION: Hispanics remain underrepresented in dementia clinical research. This one-arm trial aimed to assess the preliminary efficacy of a culturally tailored recruitment educational strategy among Hispanic older adults on dementia knowledge, research participation attitudes, and enrollment. METHOD: The recruitment strategy included 6 one-session culturally tailored dementia education events at trusted community senior centers. Participants received a pre-post survey including a 5-point Likert-type scale and the Epidemiology/Etiology Disease Scale to assess dementia knowledge, and a 4-point Likert-type scale assessing research participation attitudes. We gave participants contact information slips to complete if interested in dementia research. We also tracked participants' enrollment into the National Alzheimer's Coordinating Center Cohort. RESULTS: Dementia knowledge increased 0.9 points (5-point Likert-type scale) and 2.2 points (epidemiology/etiology disease scale, p < .001). Interest in participating in dementia research increased from 61.7% to 80.9% (p = .039), 64.0% returned their contact information slips, and 41.1% successfully enrolled into the National Alzheimer's Coordinating Center Cohort. CONCLUSION: A recruitment strategy including culturally tailored dementia education improves dementia knowledge, research participation attitudes, and enrollment among Hispanic older adults.

Locomotion in elongate fishes: A contact sport.

Despite the physical differences between water and air, a number of fish lineages are known to make terrestrial excursions on land. Many of these fishes exhibit an elongate body plan. Elongation of the body can occur in several ways, the most common of which is increasing the number of vertebrae in one or both regions of the axial skeleton--precaudal and/or caudal. Elongate species are often found in three-dimensionally complex habitats. It has been hypothesized that elongate fishes use this structure to their locomotor advantage. In this study, we consider how elongation and differences in vertebral regionalization correspond with the use of wooden pegs, which are provided as analogs to vertically oriented substrate, structures that protrude above the ground. We compare aquatic and terrestrial locomotor behaviors of Polypterus senegalus, Erpetoichthys calabaricus, and Gymnallabes typus as they move through a peg array. When considering axial elongation we find that the highly elongate species, E. calabaricus and G. typus, contact more pegs but on average move slower in both environments than P. senegalus. When considering axial regionalization, we find that the precaudally elongate species, P. senegalus and E. calabaricus, differ in the patterns of peg contact between the two environments whereas the caudally elongate species, G. typus, exhibits similar peg contact between the two environments. Our study highlights the importance of incorporating body shape and vertebral regionalization to understand how elongate fishes move in water and on land.
