Substantial evidence supports that delay of surgery after breast cancer diagnosis is associated with increased mortality risk, leading to the introduction of a new Commission on Cancer quality measure for receipt of surgery within 60 days of diagnosis for non-neoadjuvant patients. Breast cancer subtype is a critical prognostic factor and determines treatment options; however, it remains unknown whether surgical delay-associated breast cancer-specific mortality (BCSM) risk differs by subtype. This retrospective cohort study aimed to assess whether the impact of delayed surgery on survival varies by subtype (hormone [HR] + /HER2 -, HR -/HER2 -, and HER2 +) in patients with loco-regional breast cancer who received surgery as their first treatment between 2010 and 2017 using the SEER-Medicare database.

Methods: In this study, the co-expressed genes of COPD and T2DM in Gene Expression Omnibus database were identified by bioinformatics method, and the functional enrichment analysis was performed.
Objective: Piglet diarrhea poses a serious threat to piglet health and the livestock economy, and is one of the most pressing problems in animal husbandry. This study aims to investigate the genetic factors involved in piglet diarrhea and to identify key genes that regulate this condition.
Methods: We screened 600 diarrheal piglets based on unique diarrhea scores for resequencing and conducted a genome-wide association study (GWAS).
Background: The role of adult adiposity in young-onset breast cancer (YOBC) subtype risk is not well understood.
Methods: In this population-based case (n = 1812)-control (n = 1,381) study of invasive YOBC (ages <50 years), cases were identified from the Los Angeles County and Metropolitan Detroit Surveillance, Epidemiology, and End Results registries, 2010 to 2015. Area-based, frequency-matched controls were sampled from the 2010 Census.
