Qualitative evaluation of postdoctoral trainee and faculty advisor experiences within a research-intensive school of pharmacy.

BACKGROUND: Postdoctoral trainees play a vital role in securing grant funding, building alliances, and mentoring graduate students under the guidance of a mentor who can help develop their intellectual independence. However, the experiences of postdoctoral trainees, particularly within health professions schools, is largely unexplored. The purpose of this study was to investigate the experiences of postdoctoral trainees and faculty advisors at a public four-year school of pharmacy and identify areas of opportunity to improve postdoctoral training. METHODS: Focus groups and interviews were conducted to elicit participants' experiences, perceptions, and suggestions for improvement. Stakeholder groups included postdoctoral trainees and faculty who serve as postdoctoral advisors. Thematic coding was used to identify semantic themes, and summaries of participant perceptions were generated. Results were mapped to the identity-trajectory framework. RESULTS: Participants described various experiences related to intellectual growth, networking opportunities, and institutional support. In addition, participant agency was critical for developing career goals and navigating transitions. COVID-19 introduced unique challenges associated with transitioning to remote work and managing goals/motivation. Areas of opportunity were identified, such as improving infrastructure, enhancing mentoring, and enhancing communication. CONCLUSION: Postdoctoral trainees play a critical role in the success of academic institutions. Scholarly endeavors that explore postdoctoral experiences, specifically those utilizing qualitative methods, can help pharmacy education better understand and meet the needs of postdoctoral trainees and faculty advisors. This study provides insight into the experiences of postdoctoral scholars and provides evidence for improving these training programs in schools of pharmacy.

Population Pharmacokinetics of Morphine in Patients With Nonalcoholic Steatohepatitis (NASH) and Healthy Adults.

Altered expression and function of transporters in nonalcoholic steatohepatitis (NASH) patients may affect the pharmacokinetics (PK), efficacy, and safety of substrate drugs. A population pharmacokinetic (PopPK) analysis was performed to assess differences in morphine and morphine-3-glucuronide (M3G) disposition in NASH and healthy subjects. A total of 315 serum and 42 urine samples from 21 subjects (14 healthy; 7 NASH) were analyzed using NONMEM. Morphine and M3G PK were described by three- and one-compartment models, respectively. After accounting for the effect of total body weight on all clearance and volume of distribution parameters using an allometric scaling approach, NASH severity score (NASF; combination of fibrosis and nonalcoholic fatty liver disease activity scores) was the most significant predictor of differences in M3G exposure. The model predicted a linear decrease in the clearance of M3G with increasing NASF scores on a natural logarithmic scale. These results may provide some insight into the potential effect of NASH on the disposition of hepatic transporter substrates.
