Obesity, defined as a body mass index (BMI) ≥ 30, is an established risk factor for breast cancer among women in the general population after menopause. Whether elevated BMI with germline mutation BRCA1 or BRCA2 less clear because of inconsistent findings from epidemiological studies and lack mechanistic this population. Here, we show that DNA damage normal epithelia carrying BRCA positively correlated biomarkers metabolic dysfunction. In addition, RNA sequencing showed obesity-associated...

One of the main challenges in drug development for rare diseases is selecting appropriate primary endpoints pivotal studies. Although many can effectively reflect clinical benefit, their sensitivity often varies, making it difficult to determine required sample size study design and interpret final results, which may be underpowered some or all endpoints. This complexity further compounded when there a desire support regulatory claims multiple dose regimens due issues multiplicity...

ABSTRACT Background Point-of-care ultrasound is an emerging technology in critical care medicine. Despite requirements for medicine fellowship programs to demonstrate knowledge and competency point-of-care ultrasound, tools guide competency-based training are lacking. Objective We describe the development validity arguments of a assessment tool ultrasound. Methods A modified Delphi method was used develop behaviorally anchored checklists 2 applications: “Perform deep venous thrombosis study...

Reconstruction of the stage II adult-acquired flatfoot deformity (AAFD) often requires use multiple osteotomies and soft tissue procedures that may not heal well in older patients. The purpose our study was to determine whether patients than 65 years with AAFD had inferior clinical outcomes or an increased number subsequent surgical after reconstruction when compared younger patients.One-hundred forty consecutive feet (70 right, 70 left) 137 were divided into 3 groups based on age: 45...

Abstract Purpose: We evaluated the prognostic and predictive value of circulating tumor cells (CTCs) hormone receptor–positive (HR+) metastatic breast cancer (MBC) patients randomized to letrozole alone or plus bevacizumab in first-line setting (CALGB 40503). Experimental Design: Blood samples were collected at pretreatment three additional time points during therapy. The presence ≥5 CTCs per 7.5 mL blood was considered CTC positive. Association with progression-free survival (PFS) overall...

1010 Background: Stromal tumor infiltrating lymphocyte (sTIL) quantity is prognostic in primary breast cancer, yet MBC characterized by lower sTILs. No study has definitively evaluated the association of sTIL with survival outcome metastatic (met) setting without checkpoint blockade. CALGB (Alliance) 40502 was a randomized phase 3 trial 799 pts receiving first-line chemotherapy, comparing paclitaxel, nab-paclitaxel or ixabepilone bevacizumab. We hypothesized that sTILs associated MBC....

Category: Ankle Arthritis Introduction/Purpose: Peripheral vascular disease (PVD) is often cited as a contraindication for total ankle replacement (TAR); however, there are no studies looking at its impact on postoperative complications. The primary purpose of our study was to identify whether preoperative PVD increased the rate infection, irrigation and debridement, or failure implant in patients undergoing arthroplasty using large dataset.

Patient-provider communication factors have been found to affect differences between of total knee arthroplasty. Patients with limited health literacy ask fewer questions spend less time their surgeons, perceive themselves a more passive decision-making role in hand surgery clinic visits. Understanding how...
