Establishing a baseline for multilingual capabilities of medical students at the Michigan State University College of Osteopathic Medicine.

CONTEXT: The language proficiencies of Michigan State University College of Osteopathic Medicine (MSUCOM) medical students are unknown. As of 2015, approximately 8% (or roughly 25 million) of the US population over the age of five were considered "limited English proficient". Research indicates, however, that it is valuable to patients to be able to communicate in their primary language with their primary care physician. If medical students' language proficiencies were known, the medical school curriculum could be adapted to leverage or enhance a student's language proficiencies, preparing students to serve in communities where their patients language proficiencies align. OBJECTIVES: The aim of this pilot study was to survey MSUCOM medical students in order to assess their language proficiencies with two goals in mind: first, to develop medical school curriculum that would leverage student's language proficiencies, and second, to encourage student placement within diverse communities throughout the state of Michigan where these physicians-in-training speak or understand the primary language of the local community to better serve patients. METHODS: For this cross-sectional descriptive pilot study, a short, author-created survey was sent to 1,226 osteopathic medical students (OMS-I to OMS-IV) at MSUCOM. Participants were asked questions pertaining to language proficiency, number of languages spoken, prior exposure to education abroad, and demographic information. All participant data were only reported in grouped, collective, de-identified terms. Descriptive statistical analyses (frequencies, percentages) were calculated utilizing SPSS Version 25 software. RESULTS: Over the course of several months, 698 (58.7%) current MSUCOM medical students participated in the study. Of those students, 382 (54.7%) responded that they were multilingual. The top three second languages reported spoken were: English 332 (47.6%), Spanish 169 (24.2%), and Arabic 64 (9.2%). In addition, 249 (37.2%) said they had prior exposure to education abroad, and 177 (26.4%) said they had lived in another country for more than 6 months. CONCLUSIONS: The majority, 382 (54.7%), of the MSUCOM students who participated in the survey have some degree of multilingual capabilities. The student population at MSUCOM may benefit from completing primary care rotations in diverse communities within the state of Michigan. Likewise, the communities throughout Michigan may benefit from having bilingual and multilingual medical students serve in their medical facilities. Further research on the efficacy of leveraging language skills in various communities, as well as broadening the population sample, is warranted to refine and validate the observed pilot study results.

Regulation of KRAS-PAK4 axis by microRNAs in cancer.

MicroRNAs (miRNAs), often aberrantly expressed in cancer, have been implicated in the regulation of a number of critical cell survival pathways including the genes in the Kras signaling. Kras mutations are observed in more than half of cancers and its inhibition has been the focus of intense research for the past 30 years. However, Kras itself has proven to be non-druggable due in part to the absence of binding pockets for small molecule drugs. These hurdles resulted in researchers shifting their focus on targeting proteins downstream to Kras pathways. P21 activated kinase 4 (PAK4) belongs to the family of serine/threonine kinases comprising of 6 isoforms (PAK 1-6) and is considered as a key effector of Rho family of GTPases downstream of RAS. PAK4 controls critical processes such as cellular motility, proliferation and survival. Recently a number of small molecule PAK4 antagonists have been investigated in preclinical and clinical setting; albeit without any success. Emerging evidence shows that PAK is tightly regulated by a number of miRNAs that are also recognized to promote hyper-activation of oncogenic Kras signaling. Therefore, the understanding of the role of miRNAs in the regulation of PAK4 is critical to the development of therapies against this important player in the Kras pathway. Through this review, we bring forward mechanistic insights on PAK4 regulation by aberrantly expressed miRNAs in cancer and its implications on Kras signaling. We anticipate that enhanced knowledge of the miRNA-PAK4 interaction network will allow the development of successful therapies targeting this critical protein to ultimately rein in Kras.
