Deconditioning in quiescent Crohn's Disease patients with heightened fatigue perception.

Background & Objective: IBD fatigue aetiology is poorly understood. This study quantified body composition and physical function alongside proton magnetic resonance imaging (1H MRI) and spectroscopy (31P MRS) measures of organ structure and function in quiescent Crohn's Disease patients (CD) and healthy volunteers (HV), to identify a physiological basis for IBD fatigue.

Methods: Body composition was determined using DEXA and 1H MRI.

Pectin-Cellulose Nanofiber Composites: Biodegradable Materials for Modified Atmosphere Packaging.

Pectin blended with cellulose nanofiber (CNF) sourced from wood pulp has excellent potential for modified atmosphere packaging (MAP), as demonstrated with refrigerated or sliced fruits enclosed in parchment coated with pectin-CNF composites. Addition of sodium borate (NaB) augments the antioxidant capacity of the composite, most likely through the generation of unsaturated pectic acid units. Packaging materials coated with pectin-CNF-NaB composites demonstrate better humidity regulation in refrigerated spaces over a 3-week period relative to uncoated controls (50% less variation), with improved preservation of strawberries as well as a reduction in the oxidative browning of sliced apples.

Neuropathological and cerebrospinal fluid correlates of choroid plexus inflammation in progressive multiple sclerosis.

Among the intrathecal inflammatory niches where compartmentalized inflammation persists and plays a pivotal role in progressive multiple sclerosis (MS), choroid plexus (CP) has recently received renewed attention. To better characterize the neuropathological/molecular correlates of CP in progressive MS and its potential link with other brain inflammatory compartments, such as perivascular spaces and leptomeninges, the levels, composition and phenotype of CP immune infiltration in lateral ventricles of the hippocampus were examined in 40 post-mortem pathologically confirmed MS and 10 healthy donors, using immunochemistry/immunofluorescence and in-situ sequencing. Significant inflammation was detected in the CP of 21 out of the 40 MS cases (52%).

Intraoperative Parathyroid Hormone Kinetics are Variable: An In-Vivo Analysis.

Objectives: Intraoperative parathyroid hormone (IOPTH) monitoring has become routine in parathyroid surgery to facilitate less invasive techniques to treat hyperparathyroidism. Despite this, little is known about in vivo IOPTH kinetics, which can greatly affect the reliability of its interpretation.

Methods: A prospective cohort of patients undergoing routine parathyroidectomy was studied.
