Exploring the Experiences of African American Women in an Undergraduate Research Program Designed to Address the Underrepresentation of Women and Minorities in Neuroscience: A Qualitative Analysis

African American women compose a critical proportion of the potential science, technology, engineering, and mathematics (STEM) workforce of the future, yet are disproportionately represented and largely underutilized. While various programs and initiatives have been designed and implemented to target women and underrepresented minorities, the voices and experiences of African American women have been insufficiently heard or studied. This study investigates the experiences of four African American female students who participated in a 10-week undergraduate research experience (URE) program designed for the recruitment and retention of women and underrepresented minorities in STEM disciplines. Through autobiographical narratives and interviews participants shared how and in what ways the URE program influenced their career development (namely academic/career interests and choices), what they learned about their interests and choices, and what it means to them to be African American women pursuing science-related careers. Using a qualitative case study analysis, this study focuses on the unique stories of young African-American women participating in their own career development. Seven major themes emerged from the analysis of the data. Each of the participants initially entered the URE with an established interest in science, with an expressed desire for research experience, and with an interest in exploring career options in science. Through their involvement in the URE program, participants experienced a significant increase in self-knowledge and confidence, recognized the existence of social and/or science communities, and either discovered or clarified career interests and possibilities. All participants recognized value in their participation and expressed gratitude for having had the opportunity. Overall, the URE program provided a vital opportunity for participants to play an active role in their own career development. The results of this study emphasize the importance of and need to expand the URE as an avenue for career development and exploration in order to address the lack of such programming for African American women in STEM disciplines

Who Needs Microtubules? Myogenic Reorganization of MTOC, Golgi Complex and ER Exit Sites Persists Despite Lack of Normal Microtubule Tracks

A wave of structural reorganization involving centrosomes, microtubules, Golgi complex and ER exit sites takes place early during skeletal muscle differentiation and completely remodels the secretory pathway. The mechanism of these changes and their functional implications are still poorly understood, in large part because all changes occur seemingly simultaneously. In an effort to uncouple the reorganizations, we have used taxol, nocodazole, and the specific GSK3-β inhibitor DW12, to disrupt the dynamic microtubule network of differentiating cultures of the mouse skeletal muscle cell line C2. Despite strong effects on microtubules, cell shape and cell fusion, none of the treatments prevented early differentiation. Redistribution of centrosomal proteins, conditional on differentiation, was in fact increased by taxol and nocodazole and normal in DW12. Redistributions of Golgi complex and ER exit sites were incomplete but remained tightly linked under all circumstances, and conditional on centrosomal reorganization. We were therefore able to uncouple microtubule reorganization from the other events and to determine that centrosomal proteins lead the reorganization hierarchy. In addition, we have gained new insight into structural and functional aspects of the reorganization of microtubule nucleation during myogenesis

A Core Outcome Measurement Set for Pediatric Critical Care

Objectives: To identify a PICU Core Outcome Measurement Set (PICU COMS), a set of measures that can be used to evaluate the PICU Core Outcome Set (PICU COS) domains in PICU patients and their families. Design: A modified Delphi consensus process. Setting: Four webinars attended by PICU physicians and nurses, pediatric surgeons, rehabilitation physicians, and scientists with expertise in PICU clinical care or research (n = 35). Attendees were from eight countries and convened from the Pediatric Acute Lung Injury and Sepsis Investigators Pediatric Outcomes STudies after PICU Investigators and the Eunice Kennedy Shriver National Institute of Child Health and Human Development Collaborative Pediatric Critical Care Research Network PICU COS Investigators. Subjects: Measures to assess outcome domains of the PICU COS are as follows: cognitive, emotional, overall (including health-related quality of life), physical, and family health. Measures evaluating social health were also considered. Interventions: None. Measurements and Main Results: Measures were classified as general or additional based on generalizability across PICU populations, feasibility, and relevance to specific COS domains. Measures with high consensus, defined as 80% agreement for inclusion, were selected for the PICU COMS. Among 140 candidate measures, 24 were delineated as general (broadly applicable) and, of these, 10 achieved consensus for inclusion in the COMS (7 patient-oriented and 3 family-oriented). Six of the seven patient measures were applicable to the broadest range of patients, diagnoses, and developmental abilities. All were validated in pediatric populations and have normative pediatric data. Twenty additional measures focusing on specific populations or in-depth evaluation of a COS subdomain also met consensus for inclusion as COMS additional measures. Conclusions: The PICU COMS delineates measures to evaluate domains in the PICU COS and facilitates comparability across future research studies to characterize PICU survivorship and enable interventional studies to target long-term outcomes after critical illness.</p
