The Use of the Perioperative Nutrition Score in Postoperative Pediatric Inflammatory Bowel Disease Patients.

Background And Objectives: Preoperative malnutrition is associated with increased postoperative morbidity. The perioperative nutrition score (PONS) was developed to identify patients at risk of malnutrition. We sought to assess the correlation between preoperative PONS and postoperative outcomes in pediatric inflammatory bowel disease (IBD) patients.

The Y plane is a reliable CT-based reference for glenoid component positioning in shoulder arthroplasty.

Purpose: To determine the reliability of anatomic references for mediolateral component positioning in shoulder arthroplasty.

Materials And Methods: The computed tomography scans of 86 shoulders free of arthritic or anatomic deformities were studied. Two surgeons independently digitized a series of points, including the intersection of the 3 bone branches of the scapular spine (Y), the center of the glenoid surface (G), the most medial point of the scapula (MS), the cortical convergence (CC) of the anterior and posterior margins of the glenoid, the base of the coracoid (BC), the anterior (HA) and posterior (HP) margins of the subchondral bone.

Cellular interactions with polystyrene nanoplastics-The role of particle size and protein corona.

Plastic waste is ubiquitously spread across the world and its smaller analogs-microplastics and nanoplastics-raise particular health concerns. While biological impacts of microplastics and nanoplastics have been actively studied, the chemical and biological bases for the adverse effects are sought after. This work explores contributory factors by combining results from in vitro and model mammalian membrane experimentation to assess the outcome of cell/nanoplastic interactions in molecular detail, inspecting the individual contribution of nanoplastics and different types of protein coronae.

Prenatal exposure to ambient air pollutants and early infant growth and adiposity in the Southern California Mother's Milk Study.

Background: Prior epidemiological and animal work has linked in utero exposure to ambient air pollutants (AAP) with accelerated postnatal weight gain, which is predictive of increased cardiometabolic risk factors in childhood and adolescence. However, few studies have assessed changes in infant body composition or multiple pollutant exposures. Therefore, the objective of this study was to examine relationships between prenatal residential AAP exposure with infant growth and adiposity.

Recent developments in sustainably sourced protein-based biomaterials.

Research into the development of sustainable biomaterials is increasing in both interest and global importance due to the increasing demand for materials with decreased environmental impact. This research field utilises natural, renewable resources to develop innovative biomaterials. The development of sustainable biomaterials encompasses the entire material life cycle, from desirable traits, and environmental impact from production through to recycling or disposal.
