The Hispanic Paradox in endometrial cancer: A National Cancer Database study.

OBJECTIVE: To compare the overall survival of non-Hispanic white and Hispanic women with endometrial cancer. METHODS: We performed an observational retrospective cohort study of Hispanic and non-Hispanic women with endometrial cancer from the 2004-2014 National Cancer Database. Baseline characteristics were compared with the Chi-squared test for categorical variables or the Mann-Whitney U test for ordinal or continuous variables. The Kaplan-Meier method was used to estimate unadjusted survival times, which were compared with the log-rank test. Missing data was imputed using multiple imputation with chained equations. A multivariable parametric accelerated failure time model for survival was used. Sensitivity analyses were performed using matched cohort analyses of the overall cohort, and of subgroups based on stage or type. RESULTS: 112,574 non-Hispanic and 6313 Hispanic women met inclusion criteria. Five-year survival was slightly higher for Hispanic women (83.1% (82.1-84.3%) versus 81.4% (81.2-81.7%), P=0.002). Hispanic women were younger, treated at lower volume hospitals, and more often diagnosed with a type II histology and stage II-IV disease compared to non-Hispanic women (all P<0.001). With multivariable adjustment for measured confounders, Hispanic women lived 8% longer than non-Hispanic women (time-ratio (95% CI) 1.08 (1.02-1.14), P=0.01). When bias-reducing matched cohort analyses were used for sensitivity analyses, Hispanic women did not have significantly different survival than non-Hispanic women. CONCLUSION: Hispanic ethnicity was not associated with a clinically meaningful difference in survival among women with endometrial cancer.

COVID-19 Vaccine intent in appalachian patients with multiple sclerosis.

BACKGROUND: Rural people with Multiple Sclerosis (PwMS) face distinctive challenges in the COVID-19 pandemic. The purpose of this study was to determine the COVID-19 vaccine intent and factors associated with vaccine hesitancy among Appalachian adults with MS. METHOD: We conducted a cross sectional phone and in-person survey of PwMS in a large academic center in West Virginia (WV) from February to May 2021. The study sample consists of 306 adult participants. RESULTS: Among the 306 participants, 104 (33.99%) indicated vaccine hesitancy. Statistically significant factors (p<0.05) associated with vaccine hesitancy compared to those who received or intend to get vaccinated included concerns about vaccine safety, vaccine causing MS relapse, vaccine making MS medication ineffective, vaccine causing other diseases, getting the COVID-19 infection, vaccine fast approval, vaccine ingredients, how well the vaccine works, and its side-effects. Additional factors included prior bad experiences with other vaccines, history of not getting the flu vaccine, and lack of consultation about COVID-19 vaccine with healthcare providers. CONCLUSIONS: Vaccine hesitancy among Appalachian adult PwMS is higher compared to PwMS in the larger United States. Vaccine hesitancy is especially higher among those who are female, younger than 50 years old, and residing in rural areas. Concerns about vaccine safety, perception of infection risks, past vaccine behaviors and consultation with healthcare providers are important factors associated with vaccine intent. Factors influencing vaccine hesitancy in Appalachian PwMS are largely consistent with the general public, however, concerns for interaction between the vaccine and MS are specific to this population and thus could be the focus of further vaccine effort.
