Background and Objectives: Cancer as the second leading cause of death in the United States poses a huge healthcare burden. Barriers to access to advanced therapies influence the outcome of cancer treatment. In this study, we examined whether insurance types affect the quality of cancer clinical care regarding access to an important monoclonal antibody, ramucirumab. Materials and Methods: Data for 13,340 cancer patients with Purchased or Medicaid insurance from the All of Us Database were collected for this study. The Chi-square test of proportions was employed to determine the significance of patient cohort characteristics and ramucirumab usage between Purchased and Medicaid insurance groups. The independent t-test was utilized to assess the influences of other determinants on insurance types. Results: Cancer patients who are African American, with lower socioeconomic status, or with lower educational attainment are more likely to be insured by Medicaid. Analysis of survey questions demonstrated the relationship between income and education level with insurance type as Medicaid cancer patients were less likely to receive primary care and specialist physician access and more likely to request lower cost medications. In addition, those with Medicaid insurance were identified to have poorer access to expensive therapeutics like ramucirumab compared to those with Purchased insurance. Conclusions: The inequities of the US healthcare system are observed for cancer patient care; access to physicians and therapeutics are highly varied and dependent on insurance types. Socioeconomic status determines insurance type, which unfortunately generates a significant impact on cancer treatment and disease outcome.

In 2020, it is estimated that 7.8% of all live births in the United States were complicated with gestational diabetes, with around 10% of all pregnancies in North America involving gestational diabetes. GDM’s prevalence has been increasing over time, likely due to the population’s rising BMI and increasing maternal age. GDM has been long associated with increased complications in pregnancy, from preeclampsia and macrosomia in the short-term, to long term ramifications including the development of type 2 diabetes mellitus, cardiovascular disease, and potential effects on the offspring, including obesity, insulin resistance, hypertension, and increased risk of autism. Additionally, as the field of epigenetics continuously grows, we are able to further elucidate epigenetic mechanisms at play in the development of GDM and how these changes may affect the offspring. In this narrative review, we have compiled recent and relative clinical studies that highlight the role epigenetics may play in the development and perpetuation of GDM, as well as its possible effects on the offspring.
