Contribution of Nuclear Fragmentation to Dose and RBE in Carbon-Ion Radiotherapy.

Variable relative biological effectiveness (RBE) of carbon radiotherapy may be calculated using several models, including the microdosimetric kinetic model (MKM), stochastic MKM (SMKM), repair-misrepair-fixation (RMF) model, and local effect model I (LEM), which have not been thoroughly compared. In this work, we compared how these four models handle carbon beam fragmentation, providing insight into where model differences arise. Monoenergetic and spread-out Bragg peak carbon beams incident on a water phantom were simulated using Monte Carlo.

Sociodemographic inequities in overall survival among younger and older women with cervical cancer.

Purpose:  Older Black women and women living in areas of low socioeconomic status (SES) diagnosed with cervical cancer (CC) have worse overall survival (OS). The objective was to investigate associations between OS and race/ethnicity and sociodemographic factors in younger (21-64 years) and older women (≥ 65 years) diagnosed with CC using Surveillance, Epidemiology, and End Results Program data.

Methods:  This retrospective, population-based cohort study included 39,000 women ≥ 21 years diagnosed with CC diagnosed between 2006 and 2020.

U.S. national trends in cervical cancer screening by sexual orientation and race/ethnicity in cisgender women.

Introduction: Changes in up-to-date cervical cancer screening (CCS) over time by sexual orientation and race/ethnicity were estimated to identify trends in screening disparities.

Methods: This 2024 retrospective, cross-sectional analysis of National Health Interview Survey data (years 2013, 2015, 2019 and 2021) included 40,818 cisgender women aged 21-65 without hysterectomy. Joinpoint analysis was performed to calculate the annual percent change (APC) of up-to-date CCS from 2013 to 2021.

Ethnic enclaves, neighborhood socioeconomic status, and obesity among Hispanic women in Chicago: a latent profile analysis approach.

Purpose: The prevalence of obesity, a crucial risk factor for breast cancer, is markedly higher among Hispanic women. The interaction between ethnic enclaves and neighborhood socioeconomic status (SES) as a determinant of this disparity warrants further research. We aimed to identify neighborhood profiles based on ethnic enclaves and socioeconomic status to evaluate the association with obesity among Hispanic women in the metropolitan Chicago region.
