Objective. To develop and implement a multimodal structured approach to intentional interprofessional experiential education at a non-academic community hospital, and to evaluate students' perceptions of the program. Methods. A multimodal structured approach to intentional interprofessional experiential education was designed that consisted of medical and pharmacy students participating together in daily prerounds, daily teaching rounds, and once or twice weekly lunch-and-learn sessions at a non-academic community hospital. Pre-and post-experience surveys were administered to assess students' perceptions of physician and pharmacist collaboration in interprofessional education (IPE). The survey instrument included the Student Perceptions of Physician-Pharmacist Interprofessional Clinical Education, Version 2 (SPICE-2) survey. Results. Thirty-nine students, including 18 fourth-year student pharmacists from Mercer University College of Pharmacy and 21 third-year medical students from three medical schools in the Caribbean, provided informed consent and were enrolled in the eight-month study. Students' perceptions of items related to the Interprofessional Education Collaborative (IPEC) competencies, including values/ethics for interprofessional practice, roles/responsibilities, and teams and teamwork, significantly improved from the pre-to the post-experience survey. Conclusion.A multimodal structured approach to intentional interprofessional experiential education had positive effects on students' perceptions of interprofessional clinical education targeting key components of the (IPEC) competencies. This approach may be a useful tool for implementing intentional IPE in the experiential setting.

Leukemias are considered malignant clonal disorders arising from the accumulation of mutations in hematopoietic cells; the majority of these mutations are thought to be acquired somatically. Measurement of mutation frequency (Mf) at the hypoxanthine phosphoribosyltransferase (HPRT) locus has been developed as a method for estimating genomic instability. We investigated the Mf in 16 leukemic cell lines to determine whether these cell lines showed evidence of genomic instability. Although some leukemic cell lines had markedly elevated Mfs, the Mfs at the HPRT locus in leukemic cell lines were not always higher than those of B-lymphoblastoid cell lines and T lymphocytes from normal individuals. We were able to identify the HPRT mutation for 159 of 160 individual HPRT mutants. The HPRT mutations were characterized at a molecular level and classified as either gross chromosomal rearrangements (GCRs) or point mutations, such as single-nucleotide substitutions, insertions, or deletions. With rare exceptions, individual leukemic cell lines showed either point mutations or GCR, but not both. Of note, all the cell lines that primarily showed point mutations are known to be defective in mismatch repair machinery.
