The Conscientious Use of Images Illustrating Diversity in Medical Education Marketing.

An institution's marketing materials are an important part of presenting its culture. In 2018, communication professionals in the Office of Faculty Affairs, Professional Development, and Diversity at the Indiana University School of Medicine recognized after reviewing the literature that using images illustrating diversity in marketing materials may have unintended negative consequences and could potentially reflect poorly on the institution. Representations of diversity that are discordant with the actual demographics of an institution can create distrust among faculty, students, and staff who discover an institution is not as diverse or supportive of diversity as their marketing materials suggest. If institutions adopt an aspirational approach to images and depict more diversity than actual demographics reflect, the authors of this Perspective recommend that they both develop marketing materials that present a widely diverse selection of images and demonstrate transparency in their communication strategies.To improve their promotional materials, the authors conducted an analysis of their institution's strategy for selecting images for these materials, identified institutional goals related to the strategic use of images, created training materials for staff, and drafted a public-facing statement about diversity in images. These measures are a significant step forward in cultivating the ethical use of images illustrating diversity. In the future, institutions should highlight their approaches to using images to portray diversity, as well as photograph and document a wide range of events that represent diverse topics and individuals. When these images are used for marketing purposes, it is also important to ensure that they are used in an appropriate context and not selected with the single goal of presenting diversity. Future research should focus on how underrepresented students and faculty interpret the use of diverse images in marketing, as well as their preferences for the use of their own images in marketing materials portraying diversity.

Exposure of LS-180 cells to drugs of diverse physicochemical and therapeutic properties up-regulates P-glycoprotein expression and activity.

PURPOSE: Drug transporters are increasingly recognized as important determinants of variability in drug disposition and therapeutic response, both in pre-clinical and clinical stages of drug development process. The role P-glycoprotein (P-gp) plays in drug interactions via its inhibition is well established. However, much less knowledge is available about drugs effect on P-gp up-regulation. The objective of this work was to in vitro investigate and rank commonly used drugs according to their potencies to up-regulate P-gp activity utilizing the same experimental conditions. METHODS: The in vitro potencies of several drugs of diverse physicochemical and therapeutic properties including rifampicin, dexamethasone, caffeine, verapamil, pentylenetetrazole, hyperforin, and ß-estradiol over broad concentration range to up-regulate P-gp expression and activity were examined. For dose-response studies, LS-180 cells were treated with different concentrations of the selected drugs followed by P-gp protein and gene expressions analyses. P-gp functionality was determined by uptake studies with rhodamine 123 as a P-gp substrate, followed by Emax/EC50 evaluation. RESULTS: The results demonstrated a dose-dependent increase in P-gp expression and activity following treatments. At 50 uM concentration (hyperforin, 0.1 uM), examined drugs increased P-gp protein and gene expressions by up to 5.5 and 6.2-fold, respectively, while enhanced P-gp activity by 1.8-4-fold. The rank order of these drugs potencies to up-regulate P-gp activity was as following: hyperforin >>> dexamethasone ~ beta-estradiol > caffeine > rifampicin ~ pentylenetetrazole > verapamil. CONCLUSIONS: These drugs have the potential to be involved in drug interactions when administered with other drugs that are P-gp substrates. Further studies are needed to in vivo evaluate these drugs and verify the consequences of such induction on P-gp activity for in vitro-in vivo correlation purposes.

The role of family therapy in mediating adverse effects of excessive and inconsolable neonatal crying on the family system.

Prolonged and inconsolable new infant crying is 1 of the most challenging tasks for parental caregivers to ameliorate and manage. As parent(s) attempt to meet the stressors associated with this situation, multiple subsystems within the family may be adversely affected. Lasting interactional difficulties often result, interfering with the healthy development of parent-child and parent-parent dyads. This article examines these risks to the family system, suggests an important role for intervention by family practitioners, and presents recommendations for intervention by clinicians.
