Purpose: The aim of this study is to compare the detection ability of quality of life (QoL) changes and responsiveness of the KOrean QUality of life in Stomach cancer patients Study group (KOQUSS)-40 and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ). Materials and Methods: A multicenter prospective observational study was conducted to evaluate QoL changes after various gastrectomies between January 2021 and April 2022. Participants were instructed to complete the KOQUSS-40 and EORTC QLQ-C30/STO22 preoperatively and at 1, 3, 6, and 12 months postoperatively. QoL changes over time and QoL responsiveness were assessed for each questionnaire. Results: Data from 491 patients who underwent curative gastrectomy for gastric cancer at 22 institutions were analyzed. The summary scores of the KOQUSS-40 and EORTC QLQ-STO22 showed significant differences between the total and proximal gastrectomy groups (p=0.044 and p=0.038, respectively), but no difference was observed for the EORTC QLQ-C30. Dysphagia on the KOQUSS-40 was significantly different between the total and proximal gastrectomy groups (p=0.031); however, dysphagia on the EORTC QLQ-STO22 did not differ. The responsiveness of the KOQUSS-40 was similar to that of the EORTC QLQ in patients who experienced ≥ 10% body weight loss, but approximately 10% less in patients receiving adjuvant chemotherapy than the EORTC QLQ. Conclusion KOQUSS-40 has several advantages over EORTC QLQ-C30/STO22 when comparing QoL between the total and proximal gastrectomy groups. The findings provide information for researchers investigating the QoL of patients who have undergone curative gastrectomy for gastric cancer.

Background and Aims:Laparoscopic pancreaticoduodenectomy(LPD)has become a preferred approach for periampullary tumors,yet delayed gastric emptying(DGE)remains a frequent complication that hampers postoperative recovery.The nasojejunal feeding tube(NJT)is commonly used for early enteral nutrition,but its impact on DGE is controversial.This study aimed to evaluate whether intraoperative NJT placement increases the risk of DGE after LPD and to assess its influence on postoperative recovery outcomes.Methods:A retrospective cohort of 319 patients who underwent LPD at Provincial Hospital Affiliated to Shandong First Medical University from April 2017 to November 2023 was analyzed.Patients were divided into two groups based on intraoperative NJT placement(NJT group,n=200;non-NJT group,n=119).The incidence of DGE and postoperative outcomes were compared.Multivariate logistic regression and propensity score matching(PSM)were performed to identify independent risk factors for DGE.Results:The incidence of grade B/C DGE was significantly higher in the NJT group than in the non-NJT group(36.5%vs.21.8%,P=0.006).NJT placement was associated with longer postoperative hospital stay and higher hospitalization costs(both P<0.05).Multivariate analysis revealed intraoperative NJT placement(OR=1.960,95%CI=1.142-3.363,P=0.015)and intraoperative blood loss>400 mL(OR=1.921,95%CI=1.155-3.194,P=0.012)as independent risk factors for DGE.These findings were consistent after PSM.Conclusions:Prophylactic intraoperative NJT placement confers no additional benefit for postoperative recovery after LPD and is associated with a higher risk of DGE,prolonged hospitalization,and increased medical costs.Routine NJT placement should therefore be avoided,and individualized strategies should be adopted to minimize postoperative complications and enhance recovery.

Objective To investigate the effects of the culture supernatant of Faecalibacterium prausnitzii(F.prausnitzii)on intestinal barrier function and liver fibrosis progression in mice.Methods A total of 24 male C57BL/6 mice were randomly assigned to three groups:normal control group(Control),liver fibrosis model group(Model),and model mice+F.prausnitzii supernatant group(Model+S).Hepatic fibrosis was induced by intraperitoneal injection of carbon tetrachloride in both the Model group and the Model+S group over a period of 10 weeks.Following a 2-week modeling period,the mice in the Model+S group were subjected to an 8-week treatment with bacterial supernatant.The colon and liver were analyzed for pathological morphology using HE staining.Additionally,impairment of intestinal barrier function was assessed by periodic acid schiff staining,ELISA,and fluorescein isothiocyanate-dextran(FITC-Dextran)fluorescent probe.Changes in the gut microbiota structure were analyzed with 16S rDNA sequencing.The degree of liver fibrosis was assessed using sirius red staining,and the expression levels of markers associated with intestinal barrier function,liver fibrosis,and inflammation were measured using qPCR and ELISA.Results Compared with the Model group,the severity of intestinal damage and the expressions of pro-inflammatory factors in the Model+S group were decreased.Additionally,there was a significant increase in the expressions of multiple genes related to intestinal barrier function,as well as a decrease in the concentration of FITC-Dextran in peripheral blood and lipopolysaccharide in the liver(all P＜0.05),and there was an improvement in the composition of the gut microbiota.Furthermore,while the liver function and extent of liver fibrosis in the Model+S group did not show any significant differences compared to the Model group,there was a noticeable decrease in the infiltration of inflammatory cells within the liver.Additionally,the expressions of pro-inflammatory factors such as Tlr4,Il-6 and Tnf-α,and the concentration of IL-6 in the liver was significantly decreased(all P＜0.05).Conclusion The F.prausnitzii supernatant exhibits the potential to enhance intestinal barrier function and rectify gut microbiota imbalance in mice with liver fibrosis,thus reducing hepatic inflammation.However,it does not exert any significant effect on the progression of liver fibrosis.

Objective:To evaluate the association between postoperative delirium (POD) and preoperative frailty in elderly patients undergoing knee or hip arthroplasty.Methods:This nested case-control study utilized medical records from elderly patients who underwent knee or hip arthroplasty under combined spinal-epidural anesthesia at Qingdao Municipal Hospital between September 2021 and May 2023. Participants were divided into 2 groups based on clinically diagnosed POD: POD group ( n=53) and non-POD group ( n=256). Univariate analysis was conducted on suspected influencing factors, and logistic regression analysis was utilized to identify the risk factors for POD. Receiver operating characteristic and clinical decision curves were plotted to evaluate the predictive performance of these risk factors for POD. Mediation analysis was performed, and a clinically applicable nomogram was constructed to achieve visual prediction of outcomes. Results:There were statistically significant differences in age, preoperative frailty, body mass index, American Society of Anesthesiologists Physical Status classification, Memorial Delirium Assessment Scale scores, and concentrations of Aβ 42, Aβ 40, phosphorylated tau protein (p-tau protein) and tau protein, Aβ 42/tau ratio and Aβ 42/p-tau ratio in cerebrospinal fluid (CSF) between non-POD group and POD group ( P<0.05). Preoperative frailty was a risk factor for POD ( P<0.05). Mediation analysis revealed that the association between preoperative frailty and POD was mediated by CSF tau protein concentrations. The area under the receiver operating characteristic curve of preoperative frailty and CSF biomarker concentrations in predicting POD was 0.974 ( P<0.05). The clinical decision curve demonstrated that the model combining the preoperative frailty and CSF biomarker concentrations predicted a higher net benefit ( P<0.05). The clinical decision curve showed that the model combining preoperative frailty and CSF biomarker concentrations predicted a higher net benefit. Conclusions:Preoperative frailty is a risk factor for POD in elderly patients undergoing knee or hip arthroplasty, and its combination with CSF biomarker concentrations can effectively predict the occurrence of POD. CSF tau concentration mediates the association between preoperative frailty and development of POD.

Objective:To explore the training experiences of palliative care nurses participating in a prognosis disclosure workshop based on Kolb's experiential learning model, and to provide references for future educational programs in palliative care nursing.Methods:Using purposive sampling, 11 nurses were recruited who had participated in the "Palliative Care Competency Training Program for Nurses" in Shanghai between March and May 2025 and selected the Third Affiliated Hospital of Naval Medical University as their clinical training site. Semi-structured interviews were conducted, and data were analyzed using Colaizzi's seven-step method.Results:A total of three major themes emerged: a sense of benefit from enhanced competencies; complex emotional experiences; recommendations for course optimisation.Conclusions:Workshops based on Kolb's experiential learning model offer positive value in palliative care education. They effectively improve core competencies such as communication and empathy. However, the emotional experiences of nurses must also be considered, and multifaceted optimizations to the training design are recommended to further enhance training outcomes.

Purpose: This study evaluated the postoperative quality of life (QoL) after various types of gastrectomy for gastric cancer. Materials and Methods: A multicenter prospective observational study was conducted in Korea using the Korean Quality of Life in Stomach Cancer Patients Study (KOQUSS)-40, a new QoL assessment tool focusing on postgastrectomy syndrome. Overall, 496 patients with gastric cancer were enrolled, and QoL was assessed at 5 time points: preoperatively and at 1, 3, 6, and 12 months after surgery. Results: Distal gastrectomy (DG) and pylorus-preserving gastrectomy (PPG) showed significantly better outcomes than total gastrectomy (TG) and proximal gastrectomy (PG) with regard to total score, indigestion, and dysphagia. DG, PPG, and TG also showed significantly better outcomes than PG in terms of dumping syndrome and worry about cancer. Postoperative QoL did not differ significantly according to anastomosis type in DG, except for Billroth I anastomosis, which achieved better bowel habit change scores than the others. No domains differed significantly when comparing double tract reconstruction and esophagogastrostomy after PG. The total QoL score correlated significantly with postoperative body weight loss (more than 10%) and extent of resection (P<0.05 for both).Reflux as assessed by KOQUSS-40 did not correlate significantly with reflux observed on gastroscopy 1 year postoperatively (P=0.064). Conclusions Our prospective observation using KOQUSS-40 revealed that DG and PPG lead to better QoL than TG and PG. Further study is needed to compare postoperative QoL according to anastomosis type in DG and PG.

Objective:To systematically evaluate and synthesize qualitative studies on palliative care nurses' cognition and experiences in disclosing the truth about a cancer diagnosis to patients, and to provide a reference for developing comprehensive and targeted communication strategies.Methods:A systematic search was conducted in PubMed, Embase, Cochrane Library, Wiley, Web of Science, China National Knowledge Infrastructure, VIP, Wanfang Data, and China Biology Medicine disc for qualitative studies on palliative care nurses' cognition and experience regarding truth-telling to cancer patients. The search covered publications from inception to November 2024. The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Qualitative Research (2016) was used for quality appraisal, and meta-synthesis was performed using an aggregative approach.Results:A total of 12 studies were included. From these, 26 themes were extracted, which were categorized into 9 categories and ultimately synthesized into 3 integrated findings: palliative care nurses' understanding of truth-telling to cancer patients; barriers encountered by palliative care nurses in truth-telling; strategies to facilitate effective disclosure.Conclusions:Palliative care nurses recognize the value of truth-telling in cancer care but face multiple barriers in its implementation. Future efforts should focus on enhancing training, promoting interdisciplinary team collaboration, and improving public awareness to advance communication practices regarding truth-telling in palliative care.
