Clinical Outcomes After Intramedullary Nailing of Intraarticular Distal Tibial Fractures: A Retrospective Review.

Unlabelled: The objective of this study was to evaluate the clinical and functional outcomes of intra-articular distal tibial fractures after intramedullary nail (IMN) and independent fixation compared with extra-articular fracture controls.

Methods: A retrospective chart review of distal tibial fractures treated with IMN was performed. Clinical outcomes were compared between fractures with and without intra-articular involvement.

Acute Presentation of a Pseudoaneurysm After a Proximal Humerus Shaft Fracture: A Case Report.

Case: A 69-year-old woman presented with a brachial artery pseudoaneurysm causing median, ulnar, and radial nerve compressive neuropathies 8 weeks after a proximal humerus shaft fracture treated with intramedullary nailing. She underwent a brachial artery bypass with a reverse cephalic vein interposition graft and neurolysis after decompression of a large pseudoaneurysm. Postoperatively, the patient had a normal vascular examination with recovering neurological function.

A Comparison of 30-Day Perioperative Complications for Open Operative Care of Distal Upper-Extremity Fractures Treated by Orthopedic Versus Plastic Surgeons: A Study of the National Surgical Quality Improvement (NSQIP) Database.

Purpose: To determine whether surgeon specialty affects complications after open operative care of distal upper-extremity fractures.

Methods: We performed a retrospective cross-sectional study using the American College of Surgeons National Surgical Quality Improvement Database from 2005 to 2016. Patients were included if they received open operative treatment by an orthopedic or a plastic surgeon for distal radius/ulna, carpal, metacarpal, or phalangeal fracture.

Acid-enhanced conformation changes of yeast cytochrome c coated onto gold nanoparticles, a FT-IR spectroscopic analysis.

Under conditions with or without linker molecules, the effects of acidic pH on the conformation of yeast iso-1-cytochrome c coated onto gold nanoparticles (AuNPs) in correlation with color changes of a Cyt c-coated AuNPs solution/suspension were examined by Fourier transform infrared (FT-IR) spectroscopy and correlated to color change. The results of detailed secondary structural analysis revealed that although the color changes coincide with acid-induced conformational changes in Cyt c coated onto AuNPs, the pH-related conformational unfolding of Cyt c coated onto AuNPs differed dramatically from that of its counterpart in solution. For Cyt c free in solution, the acid-induced unfolding did not occur until the pH was below 3.

Development and analysis of an instrument to assess student understanding of GOB chemistry knowledge relevant to clinical nursing practice.

The General, Organic, and Biological Chemistry Knowledge Assessment (GOB-CKA) is a multiple-choice instrument designed to assess students' understanding of the chemistry topics deemed important to clinical nursing practice. This manuscript describes the development process of the individual items along with a psychometric evaluation of the final version of the items and instrument. In developing items for the GOB-CKA, essential topics were identified through a series of expert interviews (with practicing nurses, nurse educators, and GOB chemistry instructors) and confirmed through a national survey.
