Few medical students are exposed to evidence-based, multidisciplinary oncology care, and few studies in oncology education reflect consolidated pre-clinical curricula. We developed a four-week curriculum, "Frontiers in Neoplasia," for fourth-year medical students, which included didactic lectures, interactive site visits, and team-based simulations of tumor boards and clinical trial design. A mixed methods approach was utilized to investigate the course's impact on students' understanding and interest in oncology, involving pre- and post-course responses to Likert-scale and open-ended questions.

Sensory disabilities have been identified as significant risk factors for dementia but underlying molecular mechanisms are unknown. In different Drosophila models with loss of sensory input, we observe non-autonomous induction of the integrated stress response (ISR) deep in the brain, as indicated by eIF2α phosphorylation-dependent elevated levels of the ISR effectors ATF4 and XRP1. Unlike during canonical ISR, however, the ATF4 and XRP1 transcription factors are enriched in cytosolic granules that are positive for RNA and the stress granule markers Caprin, FMR1, and p62, and are reversible upon restoration of vision for blind flies.

Colorectal cancer (CRC) is the third most common cancer among men and women combined, and the second leading cause of cancer death in the US. The revised USPSTF CRC screening recommendations increased CRC screening needs across health systems, which may create particular challenges for community health centers (CHCs) given their resource constraints. The objective of our study is to assess CRC screening rates across 10 CHCs in Massachusetts and estimate the additional increase in the number of average-risk screening-eligible individuals after the revision in guidelines.

December 2024

Karsh Division of Gastroenterology and Hepatology, Comprehensive Transplant Center, Samuel Oschin Comprehensive Cancer Institute, Cedars-Sinai Medical Center, Los Angeles, California, USA.

Hepatocellular carcinoma (HCC) is a major global burden, ranking as the third leading cause of cancer-related mortality. HCC due to chronic hepatitis B virus (HBV) or C virus (HCV) infection has decreased due to universal vaccination for HBV and effective antiviral therapy for both HBV and HCV, but HCC related to metabolic dysfunction associated steatotic liver disease (MASLD) and alcohol-associated liver disease (ALD) is increasing. Biannual liver ultrasonography and serum α-fetoprotein are the primary surveillance tools for early HCC detection among high-risk patients (e.
