Chronic pain and complex regional pain syndrome are associated with alterations to the intestinal microbiota in both humans and mice. An observational cross-sectional study.

Objective: This study aimed to evaluate pain metrics and gut microbiota differences from human subjects with complex regional pain syndrome (CRPS) compared to cohabitants (HHC) and non-cohabitating (biobank) controls. In addition, we aimed evaluate longitudinal changes of gut microbiota using a mouse model of acute and chronic CRPS.

Methods: In an observational, cross-sectional study, 25 patients with CRPS and 24 household controls (HHC) were recruited, completed pain questionnaires, and submitted stool samples.

A model of relationships of teammate relations, body image, and eating behaviors among athletes.

Recent studies have identified athletes to be at elevated risk for developing disordered eating habits. However, few studies have investigated the association between teammate interactions and athletes' relationships with food and their body. To address this gap, the current study examined a model in which teammate appearance pressures were associated with disordered eating behaviors and body image concerns among varsity and club athletes who competed in a variety of sports at a US university.

Antibiotic-associated neutropenia is marked by the depletion of intestinal and associated metabolites in pediatric patients.

Prolonged antibiotic exposure causes dangerous hematologic side effects, including neutropenia, in up to 34% of patients. Murine studies established a link between the intestinal microbiota and hematopoiesis. To identify factors that predispose to neutropenia in pediatric patients, we evaluated changes in microbiota-derived metabolites and intestinal microbiota composition after prolonged courses of antibiotics.
