This paper provides a review of different dietary and exercise effects on the pathogenic gut microbiota and their metabolites associated with GPCRs in orthopaedic diseases. RESULTS: Generally, metabolites produced by gut microbiota contribute to the maintenance of bone health by activating the corresponding GPCRs, which are involved in bone metabolism, regulation of immune response, and maintenance of gut flora homeostasis. Exercise and diet can influence gut microbiota, and an imbalance in gut microbiota homeostasis can trigger a series of adverse immune and metabolic responses by affecting GPCR function, ultimately leading to the onset and progression of various orthopaedic diseases. Understanding these relationships is crucial for elucidating the pathogenesis of orthopaedic diseases and developing personalised probiotic-based therapeutic strategies. In the future, we should further explore how to prevent and treat orthopaedic diseases through GPCR-based modulation of gut microbes and their interactions.

Repeated small bowel resections can lead to the development of short bowel syndrome (SBS). It is estimated that 65-75% of CD patients are malnourished. This retrospective observational study was conducted in a Polish reference centre for home parenteral nutrition (HPN). The aim of the study was to investigate the nutritional status and characteristics of patients with CD referred to HPN and to analyse the course of their HPN treatment. <b>Methods</b>: The study group consisted of all adult patients (N = 46) with CD who qualified for HPN between November 2004 and April 2022. <b>Results</b>: The most common indication for HPN was SBS (n = 27; 58.70%), followed by ineffective gastrointestinal nutrition causing progressive malnutrition (N = 9; 19.57%), fistulas (N = 6; 13.04%), and short bowel syndrome and fistulas (N = 4; 8.70%).

Altogether, 684 child-parent pairs from the intervention group were included. Parents were required to use the mobile app to learn health knowledge, monitor children's diet and exercise behaviors, manage children's weight, and received the assessment results.
