The impact of neoadjuvant therapy in patients with left-sided resectable pancreatic cancer: an international multicenter study.

Purpose: To assess the association between neoadjuvant therapy and overall survival (OS) in patients with left-sided resectable pancreatic cancer (RPC) compared to upfront surgery.

Background: Left-sided pancreatic cancer is associated with worse OS compared to right-sided pancreatic cancer. Although neoadjuvant therapy is currently seen as not effective in patients with RPC, current randomized trials included mostly patients with right-sided RPC.

Is the use of abduction pillows crucial for post-operative rehabilitation following reverse total shoulder arthroplasty?

Background: Surgeons often use abduction pillows after reverse total shoulder arthroplasty (rTSA), but evidence for their benefits is limited. This study compares outcomes for patients using a sling with or without an abduction pillow post-operatively.

Methods: A retrospective review was conducted on patients undergoing primary rTSA.

Cultural Heterogeneity in Americans' Definitions of Racism, Sexism, and Classism: Results from a Mixed-Methods Study.

This sequential mixed-methods study examines how Americans ascribe meanings to the concepts , , and . We first conduct interviews ( = 40) using a symbolic boundaries elicitation approach, gathering examples of scenarios that do and do not "count" as racism, sexism, and classism. We then use these examples as vignettes in a nationally representative survey experiment ( = 2,000).

Coronal plane deformity in total knee arthroplasty is associated with increased operative time and disposition to skilled nursing facility.

Purpose: Studies demonstrate similar long-term Total Knee Arthroplasty (TKA) outcomes in patients with significant versus minimal preoperative coronal plane deformity. Limited short-term outcomes data, which determine costs of care, exist.

Methods: We retrospectively explored the impact of preoperative coronal plane deformity on operative time, length of stay (LOS), and discharge to skilled nursing facility (SNF) in TKA.

GaAs Solar Cells Grown Directly on V-Groove Si Substrates.

The direct epitaxial growth of high-quality III-V semiconductors on Si is a challenging materials science problem with a number of applications in optoelectronic devices, such as solar cells and on-chip lasers. We report the reduction of dislocation density in GaAs solar cells grown directly on nanopatterned V-groove Si substrates by metal-organic vapor-phase epitaxy. Starting from a template of GaP on V-groove Si, we achieved a low threading dislocation density (TDD) of 3 × 10 cm in the GaAs by performing thermal cycle annealing of the GaAs followed by growth of InGaAs dislocation filter layers.
