Associations between breast radiation dermatitis and post-mastectomy pain syndrome in patients with breast cancer: A multicenter retrospective study.

Objective: This study explores the relationship between breast radiation dermatitis (BRD) and post-mastectomy pain syndrome (PMPS) among patients with breast cancer. Both BRD and PMPS significantly impact quality of life, yet their correlation and risk factors require further investigation.

Methods: We conducted a multicenter retrospective analysis of 784 patients with breast cancer who underwent postoperative radiotherapy between 2017 and 2023.

Ultrafast Charge-Discharge Capable and Long-Life Na Mn Zr V(PO ) /C Cathode Material for Advanced Sodium-Ion Batteries.

Na MnV(PO ) /C (NMVP) has been considered an attractive cathode for sodium-ion batteries with higher working voltage and lower cost than Na V (PO ) /C. However, the poor intrinsic electronic conductivity and Jahn-Teller distortion caused by Mn inhibit its practical application. In this work, the remarkable effects of Zr-substitution on prompting electronic and Na-ion conductivity and also structural stabilization are reported.
