Among the articles reviewed, surgeons overall demonstrated insight into the benefits of palliative care but reported limited knowledge and comfort as well as a multitude of challenges to introducing palliative care to their patients. These findings indicate a need for wider implementation of strategies that allow optimal integration of palliative care with surgical decision making.
Background
Endoplasmic reticulum (ER) stress is an essential response of epithelial and immune cells to inflammation in Crohn’s disease. The presence and mechanisms that might regulate the ER stress response in subepithelial myofibroblasts (SEMFs) and its role in the development of fibrosis in patients with Crohn’s disease have not been examined.
Methods
Subepithelial myofibroblasts were isolated from the affected ileum and normal ileum of patients with each Montreal phenotype of Crohn’s disease and from normal ileum in non-Crohn’s subjects. Binding of GRP78 to latent TGF-β1 and its subcellular trafficking was examined using proximity ligation-hybridization assay (PLA). The effects of XBP1 and ATF6 on TGF-β1 expression were measured using DNA-ChIP and luciferase reporter assay. Endoplasmic reticulum stress components, TGF-β1, and collagen levels were analyzed in SEMF transfected with siRNA-mediated knockdown of DNMT1 and GRP78 or with DNMT1 inhibitor 5-Azacytidine or with overexpression of miR-199a-5p.
Results
In SEMF of strictured ileum from patients with B2 Crohn’s disease, expression of ER stress sensors increased significantly. Tunicamycin elicited time-dependent increase in GRP78 protein levels, direct interaction with latent TGF-β1, and activated TGF-β1 signaling. The TGFB1 DNA-binding activity of ATF-6α and XBP1 were significantly increased and elicited increased TGFB1 transcription in SEMF-isolated from affected ileum. The levels of ER stress components, TGF-β1, and collagen expression in SEMF were significantly decreased following knockdown of DNMT1 or GRP78 by 5-Azacytidine treatment or overexpression of miR-199a-5p.
Conclusions
Endoplasmic reticulum stress is present in SEMF of patients susceptible to fibrostenotic Crohn’s disease and can contribute to development of fibrosis. Targeting ER stress may represent a novel therapeutic target to prevent fibrosis in patients with fibrostenotic Crohn’s disease.
Background The COVID-19 pandemic resulted in a sudden increase in the need to effectively use telehealth in all realms of health care communication, including the delivery of bad news. Methods A single arm, unblinded, feasibility study was performed at a tertiary care center located in Central Virginia to explore the value and utility of providing a telehealth training program based on SPIKES to teach surgical residents and faculty best practice for disclosing difficult news via video-mediated communication (VMC). Surgical interns (categorical and preliminary), surgical residents, and surgical faculty from General, Neuro, Pediatric, Plastics, Oncology, Urology, and Vascular surgical specialties were recruited via email to voluntarily participate in a telehealth simulation-based workshop, with 33 surgical learners participating in the training and 28 completing evaluation surveys. Results Only six respondents (22%) indicated they had prior formal training on telehealth communication with patients or families, while 13 (46%) said they had prior experience giving bad news via telehealth. Comments about improving the training focused on providing more scenarios to practice and more time for feedback. Overall, 25 learners (86%) agreed the activity was a valuable learning experience and the majority (61%) of responses were positive for future use of telehealth for breaking bad news. Discussion Practicing communication skills with VMC was found to be valuable by surgical interns, residents, and faculty. Formal training should be provided for surgeons at every stage of training and practice to improve skill in the delivery of bad news to patients and their families.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
