Attracting Medical Students to Family Medicine: An Historical View.

BACKGROUND AND OBJECTIVES: In 2018, the 25 x 2030 Collaborative was created. Its goal is to "increase the proportion of US medical school graduates who choose family medicine (FM) to 25% by 2030." The purpose of this study was to take a deeper look at the history of medical student interest in FM from the earliest data to the present, both after the match and those who are FM interns after July 1. METHODS: We used publicly available match data, primarily from the National Resident Matching Program website, a series of articles published for nearly 30 years in Family Medicine on match results, and the American Academy of Family Physicians website. RESULTS: The total number of FM residents is growing (4,493 matched in 2021). After the managed care era in the mid-1990s, there was a collapse in interest among allopathic graduates that bottomed out at 6.8% graduates matching in FM by 2009; this rate has only slowly increased to 8.1% in 2021. Interest has been essentially flat for the last 10 years, and is lower than the percentage match rate prior to the managed care era (9.9% to 14.0%). There was more variability among osteopathic students, but interest has never been greater than 23%. Including the allopathic and osteopathic students who join FM residencies after the match does not appreciably alter these results. CONCLUSIONS: The 25 x 30 Collaborative will likely fail to reach its goal.

Radiofrequency treatment alters cancer cell phenotype.

The importance of evaluating physical cues in cancer research is gradually being realized. Assessment of cancer cell physical appearance, or phenotype, may provide information on changes in cellular behavior, including migratory or communicative changes. These characteristics are intrinsically different between malignant and non-malignant cells and change in response to therapy or in the progression of the disease. Here, we report that pancreatic cancer cell phenotype was altered in response to a physical method for cancer therapy, a non-invasive radiofrequency (RF) treatment, which is currently being developed for human trials. We provide a battery of tests to explore these phenotype characteristics. Our data show that cell topography, morphology, motility, adhesion and division change as a result of the treatment. These may have consequences for tissue architecture, for diffusion of anti-cancer therapeutics and cancer cell susceptibility within the tumor. Clear phenotypical differences were observed between cancerous and normal cells in both their untreated states and in their response to RF therapy. We also report, for the first time, a transfer of microsized particles through tunneling nanotubes, which were produced by cancer cells in response to RF therapy. Additionally, we provide evidence that various sub-populations of cancer cells heterogeneously respond to RF treatment.
