Association Between Colorectal Cancer Screening and Survival in Patients Older Than 70 Years: Results of A National Multicenter Retrospective Study

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background Colorectal cancer screening mainly targets a population between 50 and 70 years of age; however, it is inconsistently implemented in people over 70. The aim of this study was to analyze the association between colorectal cancer (CRC) screening, postoperative mortality, and perioperative and oncologic outcomes in a large population ...

Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach

open access: yesThe Journal of Wildlife Management, EarlyView.
We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

Deep learning of wrist accelerometry from UK Biobank data identifies early movement signatures of knee osteoarthritis up to 5 years before diagnosis

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study aims to test whether week‐long wrist accelerometry combined with deep learning can (i) distinguish healthy individuals from people with knee osteoarthritis (KOA), (ii) separate prodromal KOA from established KOA, and (iii) identify individuals who will receive a KOA diagnosis within 5 years.

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

open access: yesMacromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.
