Enhancing Culturally Responsive Practice in a District: Engaging Families through Culturally Responsive Practice
Thesis advisor: Martin ScanlanAs the populations of public schools in the United States grow increasingly more diverse, it is critical for district and school leaders to understand how educators make sense of their responsibility to improve outcomes for historically marginalized students. Culturally responsive practice (CRP) is a framework of beliefs and practices to enhance these students’ success. Additionally, it is well established that family engagement in schools also supports student achievement. This qualitative case study explores the intersection of CRP and family engagement by focusing on two research questions: (1) How do educators understand CRP in efforts to engage families of marginalized students and (2) How do educators enact that understanding in practice? It is part of a larger case study examining understanding and enactment of CRP in a diverse Massachusetts school district. Along with Mapp’s (2013) Dual Capacity Building Framework of family engagement, I apply Maitlis’ (2005) organizational sensemaking theory to data collected from semi-structured interviews, document review and an online survey. Findings reveal that educators understood CRP in regards to family engagement as the need to know students and families and recognize differences in their cultures. Also, educator understanding emanates from both personal and professional experiences including learning from colleagues, students and families. However, educators lack a common definition or understanding of CRP in regards to family engagement. Consequently, family engagement practices vary and tend to be more traditional versus reflective of CRP. This study revealed the need for stronger district direction and support for CRP and family engagement.Thesis (EdD) — Boston College, 2020.Submitted to: Boston College.

Dysregulation of metabolic-associated pathways in muscle of breast cancer patients: preclinical evaluation of interleukin-15 targeting fatigue
Background Breast cancer patients report a perception of increased muscle fatigue, which can persist following surgery and standardized therapies. In a clinical experiment, we tested the hypothesis that pathways regulating skeletal muscle fatigue are down-regulated in skeletal muscle of breast cancer patients and that different muscle gene expression patterns exist between breast tumour subtypes. In a preclinical study, we tested the hypothesis that mammary tumour growth in mice induces skeletal muscle fatigue and that overexpression of the cytokine interleukin-15 (IL-15) can attenuate mammary tumourinduced muscle fatigue. Methods Early stage non-metastatic female breast cancer patients (n = 14) and female non-cancer patients (n = 6) provided a muscle biopsy of the pectoralis major muscle during mastectomy, lumpectomy, or breast reconstruction surgeries. The breast cancer patients were diagnosed with either luminal (ER+ /PR+ , n = 6), triple positive (ER+ /PR+ /Her2/neu+ , n = 5), or triple negative (ER/PR/Her2/neu, n = 3) breast tumours and were being treated with curative intent either with neoadjuvant chemotherapy followed by surgery or surgery followed by standard post-operative therapy. Biopsies were used for RNA-sequencing to compare the skeletal muscle gene expression patterns between breast cancer patients and non-cancer patients. The C57BL/6 mouse syngeneic mammary tumour cell line, E0771, was used to induce mammary tumours in immunocompetent mice, and isometric muscle contractile properties and fatigue properties were analysed following 4 weeks of tumour growth. Results RNA-sequencing and subsequent bioinformatics analyses revealed a dysregulation of canonical pathways involved in oxidative phosphorylation, mitochondrial dysfunction, peroxisome proliferator-activated receptor signalling and activation, and IL-15 signalling and production. In a preclinical mouse model of breast cancer, the rate of muscle fatigue was greater in mice exposed to mammary tumour growth for 4 weeks, and this greater muscle fatigue was attenuated in transgenic mice that overexpressed the cytokine IL-15. Conclusions Our data identify novel genes and pathways dysregulated in the muscles of breast cancer patients with early stage non-metastatic disease, with particularly aberrant expression among genes that would predispose these patients to greater muscle fatigue. Furthermore, we demonstrate that IL-15 overexpression can attenuate muscle fatigue associated with mammary tumour growth in a preclinical mouse model of breast cancer. Therefore, we propose that skeletal muscle fatigue is an inherent consequence of breast tumour growth, and this greater fatigue can be targeted therapeutically
Global health learning outcomes in pharmacy students completing international advanced pharmacy practice experiences
© 2020, American Association of Colleges of Pharmacy. All rights reserved. Objective. To examine the global health learning outcomes of Doctor of Pharmacy (PharmD) students from three US schools who participated in international advanced pharmacy practice experiences (APPEs). Methods. A mixed-methods, prospective study was used to assess fourth-year PharmD students at three US pharmacy schools who participated in an international APPE during the 2017-2018 academic year and a matched cohort (control group) of PharmD students who did not participate in an international APPE. To evaluate students’ self-perceived growth in the Consortium of Universities for Global Health (CUGH) competencies, all students completed a 13-item retrospective pre-post instrument using a five-point Likert scale. The students who had completed an international APPE were invited to participate in a focus group (N522). Paired and independent t tests and multiple linear regression were used to analyze data. Qualitative open-ended questions and focus group data were mapped to knowledge, skills, and attitudes themes. Results. The students who completed an international APPE (N581) showed significantly more growth in CUGH competencies than students who did not (mean improvement in total score of 10.3 [7.0] vs 2.4 [6.0]). International APPE participation was the only significant predictor of growth in CUGH competencies. The international APPE students reported improvements in cultural awareness and appreciation, communication skills, problem-solving skills, adaptability, self-awareness, personal and professional outlook, and global health perspective. Conclusion. Pharmacy students’ participation in international APPEs led to significant improvement in all CUGH competencies. The CUGH competency framework appears to be a suitable instrument to assess pharmacy students’ global health learning outcomes
Global health learning outcomes by country location and duration for international experiences
© 2020 American Association of Colleges of Pharmacy. Objective. To determine the impact of country income classification and experience duration on learning outcomes for student pharmacists participating in international advanced pharmacy practice experiences (APPEs). Methods. A mixed-methods, longitudinal study evaluated 81 fourth-year student pharmacists participating in an international APPE through one of three US universities. A pre-post survey was administered to evaluate students’ self-perceived growth across 13 competencies established by the Consortium of Universities for Global Health (CUGH). The survey included four additional open-ended questions. Student pharmacists were also invited to participate in a focus group. Paired and independent t tests and multiple linear regression were conducted. Qualitative survey and focus group data underwent a two-cycle, open-coding process using conventional content analysis. Results. Students who completed their APPE in a low-to middle-income country had greater growth in all CUGH competency statements compared to those who completed their APPE in a high-income country. Completing the APPE in a low-to middle-income country and prior travel for non-vacation purposes were significant predictors of student growth. Students who went to a low-to middle-income country demonstrated increased cultural sensitivity, more patient-centered care, and skill development, while students who went to a high-income country displayed increased knowledge regarding differ-ences in health care system components, pharmacy practice, pharmacy education, and an appreciation for alternative patient care approaches. Conclusion. Learning outcomes differed between students who completed an APPE in a high-income rather than a low-to middle-income country, with both types of locations providing valuable educational opportunities and professional and personal development
The Role of Preoperative Bilateral Breast Magnetic Resonance Imaging in Patient Selection for Partial Breast Irradiation in Ductal Carcinoma In Situ
Purpose. Women with ductal carcinoma in situ (DCIS) are often candidates for breast-conserving therapy, and one option for radiation treatment is partial breast irradiation (PBI). This study evaluates the use of preoperative breast magnetic resonance imaging (MRI) for PBI selection in DCIS patients. Methods. Between 2002 and 2009, 136 women with newly diagnosed DCIS underwent a preoperative bilateral breast MRI at Mayo Clinic in Florida. One hundred seventeen women were deemed eligible for PBI by the NSABP B-39 (National Surgical Adjuvant Breast and Bowel Project, Protocol B-39) inclusion criteria using physical examination, mammogram, and/or ultrasound. MRIs were reviewed for their impact on patient eligibility, and findings were pathologically confirmed. Results. Of the 117 patients, 23 (20%) were found ineligible because of pathologically proven MRI findings. MRI detected additional ipsilateral breast cancer in 21 (18%) patients. Of these women, 15 (13%) had more extensive disease than originally noted before MRI, and 6 (5%) had multicentric disease in the ipsilateral breast. In addition, contralateral breast cancer was detected in 4 (4%). Conclusions. Preoperative breast MRI altered the PBI recommendations for 20% of women. Bilateral breast MRI should be an integral part of the preoperative evaluation of all patients with DCIS being considered for PBI
Ex Vivo treatment of coronary artery endothelial cells with serum post-exercise training offers limited protection against in vitro exposure to FEC-T chemotherapy
Background: Chemotherapy treatment for breast cancer associates with well-documented cardiovascular detriments. Exercise has shown promise as a potentially protective intervention against cardiac toxicity. However, there is a paucity of evidence for the benefits of exercise on the vasculature. Objectives: This study aimed to determine the effects of chemotherapy on the vascular endothelium; and if there are protective effects of serological alterations elicited by an exercise training intervention. Methods and Results: 15 women participated in a 12-week home-based exercise intervention consisting of three high-intensity interval sessions per week. Human coronary artery endothelial cells (HCAEC) were exposed to physiological concentrations of 5-fluorouracil, epirubicin, cyclophosphamide (FEC) and docetaxel to determine a dose-response. Twenty-4 hours prior to FEC and docetaxel exposure, HCAECs were preconditioned with serum collected pre- and post-training. Annexin V binding and cleaved caspase-3 were assessed using flow cytometry and wound repair by scratch assays. Chemotherapy exposure increased HCAEC Annexin V binding, cleaved caspase-3 expression in a dose-dependent manner; and inhibited wound repair. Compared to pre-training serum, conditioning HCAECs with post-training serum, reduced Annexin V binding (42% vs. 30%, p = 0.01) when exposed to FEC. For docetaxel, there were no within-group differences (pre-vs post-exercise) for Annexin V binding or cleaved caspase-3 expression. There was a protective effect of post-training serum on wound repair for 5-flurouracil (p = 0.03) only. Conclusion: FEC-T chemotherapy drugs cause significant damage and dysfunction of endothelial cells. Preconditioning with serum collected after an exercise training intervention, elicited some protection against the usual toxicity of FEC-T, when compared to control serum
