Post-operative Fluid Restriction to Prevent Delayed Hyponatremia after Endoscopic Transsphenoidal Surgery.

Background: Readmission following endoscopic endonasal transsphenoidal surgery (EETS) for pituitary neuroendocrine tumor (PitNET) and other sellar pathology is most commonly due to delayed hyponatremia. Studies suggest post-operative fluid restriction (FR) reduces delayed hyponatremia. We present a prospective randomized controlled study evaluating post-EETS FR.

Diagnosis of prosthetic vascular graft infection using the management aortic graft infection collaboration (MAGIC) criteria.

BackgroundVascular graft infection (VGI) is a devastating complication that necessitates immediate diagnosis to reduce morbidity and mortality. In 2016, The Management of Aortic Graft Infection Collaboration (MAGIC) proposed a diagnostic algorithm for identifying aortic graft infection which uses clinical, radiological, and laboratory findings to determine risk. The purpose of this study was to retrospectively validate the MAGIC criteria for VGI diagnosis and potentially broaden its application.

Patterning Functional Proteins in Ultrabithorax-Based Materials.

The ability to add bioactivities, such as cell signaling or ligand recognition, to biomaterials has generated the potential to include multiple bioactivities into a single material. In some cases, it is desirable to localize these activities to different areas of the biomaterial, creating functional patterns. While photolithography and 3D printing have been effective techniques for patterning functions in many materials, patterning remains a challenge in materials composed of protein, in part due to how these materials are artificially assembled.

Analysis of twelve human milk oligosaccharides over fifteen months post-partum in human milk from Chinese mothers.

Human milk Oligosaccharides (HMOs) are a major component in human milk and recognized to play an important role in modulating gut microbiota, intestinal cell response, and the development of the brain and immune system. While HMOs levels from Chinese mothers across different regions of China have been reported, data from Hebei are lacking. Twelve HMOs were measured from a cross-section of Hebei Han mothers over a 15-month lactation period.
