ABSTRACT

Muscle diseases and aging are associated with impaired myogenic stem cell self-renewal and fewer proliferating progenitors (MPs). Importantly, distinct metabolic states induced by glycolysis or oxidative phosphorylation have been connected to MP proliferation and differentiation. However, how these energy-provisioning mechanisms cooperate remain obscure. Herein, we describe a mechanism by which mitochondrial-localized transcriptional co-repressor p107 regulates MP proliferation. We show p107 directly interacts with the mitochondrial DNA, repressing mitochondrial-encoded gene transcription. This reduces ATP production by limiting electron transport chain complex formation. ATP output, controlled by the mitochondrial function of p107, is directly associated with the cell cycle rate. Sirt1 activity, dependent on the cytoplasmic glycolysis product NAD+, directly interacts with p107, impeding its mitochondrial localization. The metabolic control of MP proliferation, driven by p107 mitochondrial function, establishes a cell cycle paradigm that might extend to other dividing cell types.

ABSTRACT

INTRODUCTION: Effective communication as part of an interprofessional team is a required standard of pharmacy education. The Situation, Background, Assessment, Recommendation (SBAR) communication technique is an evidence-based method shown to improve patient safety, and is embedded in some curricula of pharmacy and other health care professions. The aim of this study is to determine whether students can utilize the SBAR communication technique during an interprofessional skills assessment one year following initial instruction. METHODS: Students are initially trained on the SBAR technique in an interprofessional setting using the Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) method in the fall of the second professional year. One year later, students participated in a simulated interaction with a physician as part of the pulmonary module of the pharmacotherapeutics series. Faculty evaluators noted how many and which components of the SBAR technique students used during the interaction. The simulation was run for two academic years, results of which were compared. RESULTS: There was a significant difference in the number of students who used all four components of SBAR. A significant difference also existed between the use of the "situation" and "background" components. CONCLUSION: The TeamSTEPPS method appears to be an effective method to train students on the SBAR communication technique and results in long term retention. Pharmacy programs should consider the use of the TeamSTEPPS method early in their curricula.

ABSTRACT

Objective. To determine factors influencing Doctor of Pharmacy (PharmD) students' selection of advanced pharmacy practice experiences (APPEs) in one school of pharmacy. Methods. In their final year, PharmD students are required to complete a minimum of 1440 hours of experiential education, including ambulatory, community, inpatient general medicine, and hospital/health system APPEs, and elective APPEs. Third-year (P3) and fourth-year (P4) PharmD students were invited to complete an anonymous online survey to determine what factors impacted their decision process when selecting their required experiences. Students selected up to five factors that most influenced their selection of APPEs. Factors included areas of interest, size of institution, location, future employment, preceptor reputation, rotation hours, faculty rotation, non-faculty rotation, peer recommendation, cost/housing, level of difficulty, size of institution, and whether the site offered a residency program. Results. Of the 143 students enrolled, 100% responded to the survey. Students in both classes (71 P3 and 72 P4 students) selected location as the number one factor that influenced their decision when selecting required APPEs. Cost/housing was the second most important factor overall for P3 students, while peer recommendation was the second most important factor overall for P4 students. Conclusion. Location was the driving factor behind P3 and P4 pharmacy students' selection of APPE sites. Schools should consider establishing more APPE sites that offer housing to reduce cost. Further research into the factors that influence ranking on APPE electives is warranted.

ABSTRACT

Goodman and Gilman's The Pharmacological Basis of Therapeutics (GGPBT) has been a cornerstone in the education of pharmacists, physicians, and pharmacologists for decades. The objectives of this study were to describe and evaluate the 13th edition of GGPBT on bases including: (1) author characteristics; (2) recency of citations; (3) conflict of interest (CoI) disclosure; (4) expert evaluation of chapters. Contributors' (N = 115) sex, professional degrees, and presence of undisclosed potential CoI-as reported by the Center for Medicare and Medicaid's Open Payments (2013-2017)-were examined. The year of publication of citations was extracted relative to Katzung's Basic and Clinical Pharmacology (KatBCP), and DiPiro's Pharmacotherapy: A Pathophysiologic Approach (DiPPAPA). Content experts provided thorough chapter reviews. The percent of GGPBT contributors that were female (20.9%) was equivalent to those in KatBCP (17.0%). Citations in GGPBT (11.5 ± 0.2 years) were significantly older than those in KatBCP (10.4 ± 0.2) and DiPPAPA (9.1 ± 0.1, p < 0.0001). Contributors to GGPBT received USD 3 million in undisclosed remuneration (Maximum author = USD 743,718). In contrast, DiPPAPA made CoI information available. Reviewers noted several strengths but also some areas for improvement. GGPBT will continue to be an important component of the biomedical curriculum. Areas of improvement include a more diverse authorship, improved conflict of interest transparency, and a greater inclusion of more recent citations.
