Simulation Training of Endoscopy Staff to Improve Patient Experience in Colonoscopy

ABSTRACT: Some patients experience a degree of pain and discomfort during endoscopic examination of the large bowel. Sedatives and analgesics may be administered in low doses. Excessive dosage or intense pain may lead to hypotension and impaired level of consciousness. The purpose of the present study was to determine if simulation training of endoscopy staff in preventing pain and handling acute complications through effective teamwork could improve the quality of colonoscopy from the patients’ perspective.

Project description:Abstract Objective: Osteoarthritis (OA) is accompanied by severe and debilitating pain that current analgesics are unable to fully alleviate. A multitude of signaling molecules, pathways, and cells have been identified as regulators of OA pain. Fatty acid binding protein 5 (FABP5) regulates pain in other disease states and we hypothesized that it is involved in the regulation of OA pain. Design: This was a combined clinical and pre-clinical study. Human synovial and osteochondral tissues collected during total knee arthroplasty were subjected to immunohistochemical analyses to identify the spatial expression patterns of FAB5, COX1, COX2, and macrophages. In addition, synovial specimens were cultured the presence and absence of SBFI-103, a selective FABP5 inhibitor, and cytokines and chemokines levels were measured. The rat monoiodoacetate (MIA) model of OA was then enlisted to evaluate the efficacy of SBFI-103 in alleviating OA pain. Finally, RNAseq was performed to identify alterations in synovial gene expression in vehicle and SBFI-103 treated MIA rats. Results: FABP5 expression was present in clinical OA tissues, with higher expression seen higher grade OA and no apparent differences between genders. Furthermore, FABP5 staining colocalized with CD14+ cells, indicating a macrophage origin of FABP5. Synovial specimens secreted CCL2, IL6, IL8, CXCL1, MIF, and Serpin E1 in vitro and treatment with SBFI-103 attenuated CCL2, IL6, IL8, and CXCL1, but not MIF and Serpin E1. Twenty-eight days after MIA injection, rats exhibited histological joint degradation and significant incapacitance. Ketoprofen treatment partially reduced incapacitance and naproxen had no effect; however, SBFI-103 showed a dose dependent alleviation of incapacitance that was independent of cannabinoid or PPARα receptor activity. RNAseq analyses identified differential expression of >6,000 transcripts compared to contralateral controls in vehicle treated rats and only 513 after SBFI-103 treatment. Notably, CCL2, CCL7, CCL9, and CXCL1were upregulated in vehicle treated rats, but not those treated with SBFI-103, and this was confirmed with qPCR. Conclusions: Our results show that FABP5 is upregulated in clinical and preclinical OA tissues and that its inhibition lowers pronociceptive signaling and reduces OA pain, indicating that FABP5 inhibitors may constitute a novel class of analgesics to treat OA.
