RESUMO

OBJECTIVE: Design thinking is a creative problem-solving process used to better understand users' needs and experiences so that a product or service can be improved. Its emphasis on empathy, iterative prototyping, and participatory collaboration make it an ideal methodology for innovation in medical education. We apply this framework to the virtual rheumatology fellowship interview process so that interviews can become more applicant centered. METHODS: This educational quality improvement project uses a design-thinking framework to identify opportunities and challenges for rheumatology fellowship applicants. The investigators use the 5-step process (Empathize, Define, Ideate, Prototype, Test) and incorporate rapid qualitative analysis of semistructured interviews to innovate the interview experience. The iterative and collaborative nature of this process has empowered participants to codesign an applicant-centered interview experience. RESULTS: Interviews with fellowship applicants (n = 9), fellow physicians (n = 4), and faculty members (n = 3) identified three major dynamics of the interview process: (1) Is it a safe environment to ask questions? (2) How do I exchange information effectively? and (3) How do I fit all these data into the bigger picture? Creative brainstorming techniques at a series of three workshops yielded four prototypes emphasizing customization, hybridization, facilitation, and preparation. A finalized applicant-centered interview template was devised in preparation for the 2023-2024 application season. CONCLUSION: Design thinking has yielded insights into three important dynamics that drive applicant experiences. These insights allow for a redesign of processes so that virtual interviews can be more applicant centered. This framework allows for further iterations and modifications as the needs of applicants and programs evolve over time.

RESUMO

BACKGROUND: Several biologic mechanisms, including inflammation and immune changes, have been proposed to explain the role of obesity in prostate cancer (CaP) progression. Compared to men of a healthy weight, overweight and obese men are more likely to have CaP recurrence post-prostatectomy. Obesity is related to inflammation and immune dysregulation; thus, weight loss may be an avenue to reduce inflammation and reverse these immune processes. OBJECTIVES: This study explores the reversibility of the biological mechanisms through intentional weight loss using a comprehensive weight management program in men undergoing prostatectomy. Outcomes include blood and tissue biomarkers, microtumor environment gene expression, inflammation markers and Dietary Inflammatory Index (DII) scores. METHODS: Twenty overweight men undergoing prostatectomy participated in this study. Fifteen men chose the intervention and 5 men chose the nonintervention group. The intervention consisted of a comprehensive weight loss program prior to prostatectomy and a weight maintenance program following surgery. Prostate tissue samples were obtained from diagnostic biopsies before the intervention and prostatectomy samples after weight loss. Blood samples and diet records were collected at baseline, pre-surgery after weight loss and at study end after weight maintenance. Immunohistochemistry and NanoString analysis were used to analyze the tissue samples. Flow cytometry was used to assess circulating immune markers. Inflammation markers were measured using Luminex panels. RESULTS: The intervention group lost >5% body weight prior to surgery. DII scores improved during the weight loss intervention from baseline to pre-surgery (P = 0.002); and between group differences were significant (P = 0.02). DII scores were not associated with IL-6 nor hsCRP. In the intervention, CXCL12, CXCR7, and CXCR4 (C-X-C motif chemokine ligand/receptor) and Ki67 expression decreased in the prostate tissue from biopsy to surgery (P = 0.06), yet plasma CXCL12 increased during the same timeframe (P = 0.009). The downregulation of several genes (FDR<0.001) was observed in the intervention compared to the non-intervention. Changes in immune cells were not significant in either group. CONCLUSION: This feasibility study demonstrates that in overweight men with localized CaP, weight loss alters blood, and tissue biomarkers, as well as tumor gene expression. More research is needed to determine the biological and clinical significance of these findings.
