Association of Race, Ethnicity, Language, and Insurance with Time to Treatment Initiation Among Women with Breast Cancer at an Urban, Academic, Safety-Net Hospital.

Introduction: Initial treatment for nonmetastatic breast cancer is resection or neoadjuvant systemic therapy, depending on tumor biology and patient factors. Delays in treatment have been shown to impact survival and quality of life. Little has been published on the performance of safety-net hospitals in delivering timely care for all patients.

Association of Race, Ethnicity, Insurance, and Language and Rate of Breast-Conserving Therapy Among Women With Nonmetastatic Breast Cancer at an Urban, Safety-Net Hospital.

Introduction: Breast-conserving therapy (BCT), specifically breast-conserving surgery (BCS) and adjuvant radiation, provides an equivalent alternative to mastectomy for eligible patients. However, previous studies have shown that BCT is underused in the United States, particularly among marginalized demographic groups. In this study, we examine the association between race, ethnicity, insurance, and language and rate of BCS among patients treated at an academic, safety-net hospital.

Mitigating disparities in breast cancer treatment at an academic safety-net hospital.

Purpose: Among women with non-metastatic breast cancer, marked disparities in stage at presentation, receipt of guideline-concordant treatment and stage-specific survival have been shown in national cohorts based on race, ethnicity, insurance and language. Little is published on the performance of safety-net hospitals to achieve equitable care. We evaluate differences in treatment and survival by race, ethnicity, language and insurance status among women with non-metastatic invasive breast cancer at a single, urban academic safety-net hospital.

Impact of Race, Ethnicity, Primary Language, and Insurance on Reconstruction after Mastectomy for Patients with Breast Cancer at an Urban, Academic Safety-Net Hospital.

Background: Disparities in breast reconstruction have been observed in national cohorts and single-institution studies based on race, ethnicity, insurance, and language. However, little is known regarding whether safety-net hospitals deliver more or less equitable breast reconstruction care in comparison with national cohorts.

Study Design: We performed a retrospective study of patients with either invasive breast cancer or ductal carcinoma in situ diagnosed and treated at our institution (January 1, 2009, to December 31, 2014).

Superconducting aluminum heat switch with 3 nΩ equivalent resistance.

Superconducting heat switches with extremely low normal state resistances are needed for constructing continuous nuclear demagnetization refrigerators with high cooling power. Aluminum is a suitable superconductor for the heat switch because of its high Debye temperature and its commercial availability in high purity. We have constructed a high quality Al heat switch whose design is significantly different than that of previous heat switches.
