Methods: Ninety-two patients scheduled for elective surgery in the surgical department between August 2021 and August 2023 were selected and divided into groups using a random number table. The observation group received preoperative psychological interventions, while the reference group received standard preoperative care. Anxiety and depression scores, fear grading, vital signs, and self-efficacy levels were compared. Results: After the intervention, the anxiety and depression scores in the observation group were lower than those in the reference group, and the proportion of fear graded as Level I was higher. During the waiting period and 15 minutes before entering the operating room, vital sign levels in the observation group were lower than those in the reference group. Additionally, the self-efficacy scores of the observation group were significantly higher than those of the reference group (P < 0.05). Conclusion: Preoperative psychological interventions can alleviate negative emotions, stabilize preoperative vital signs, and significantly improve self-efficacy in patients undergoing elective surgery, demonstrating high feasibility for implementation.展开更多

文摘Granular composite(GC)hydrogels have attracted considerable interest in biomedical applications due to their versatile printability and exceptional mechanical properties.However,the lack of comprehensive design guidelines has limited their optimal engineering,as the factors influencing their mechanical performance and printability remain largely unexamined.In this study,we developed GC hydrogels by integrating microgels with interstitial matrices of photocrosslinkable gelatin methacrylate(GelMA).We utilized confocal microscopy and nanoindentation analyses to investigate the spatial distribution and mechanical behavior of these hydrogels.Our findings indicate that the mechanical and rheological properties of GC hydrogels can be precisely tailored by adjusting the volume fraction and size of the microgels.Furthermore,hydrogen bonds were identified as significant contributors to compressive performance,although they had minimal effect on cyclic mechanical behavior.Compared to bulk GelMA hydrogels,GC hydrogels demonstrated enhanced printability and remarkable superelasticity.As a proof of concept,we illustrated their dual printability in embedded printing to create prosthetic liver models for preoperative planning.This study provides valuable insights into the design and optimization of GC hydrogels for advanced biomedical applications.
文摘This editorial critically evaluated Liu et al's recent retrospective analysis of 283 Chinese patients with resectable pancreatic ductal adenocarcinoma(PDAC)that validated a preoperative computed tomography-based risk scoring system origi-nally developed in South Korea.The scoring system incorporated five parame-ters:(1)Tumor size;(2)Portal venous phase density;(3)Necrosis;(4)Peripan-creatic infiltration;and(5)Suspected metastatic lymph nodes.While demonstra-ting satisfactory recurrence prediction capability without requiring complex tech-nologies,thereby supporting clinical utility in Chinese populations,the study exhibited notable limitations.Most analyzed patients lacked neoadjuvant chemo-therapy exposure,resulting in underrepresentation of low-risk subgroups.Addi-tionally,the short follow-up duration potentially compromised long-term progno-stic assessment.Contemporary advances in radiomics coupled with machine learning have enhanced multimodal data integration for PDAC management.However,clinical implementation continues to confront challenges including variability in imaging parameters,incomplete understanding of molecular underpinnings,and confounding treatment effects.Future investigations should prioritize developing multidimensional predictive frameworks that synergize radiographic,molecular,and clinical data.Prospective multicenter validation and artificial intelligence-powered real-time risk stratification systems represent essential steps to overcome current barriers in precision medicine translation,ultimately advancing personalized therapeutic strategies for PDAC.
文摘Endoscopic retrograde cholangiopancreatography(ERCP)is a vital tool for diagnosing and treating biliary and pancreatic disorders,but its safety and efficacy are marred by preoperative gastric retention.Jia et al retrospectively analyzed 190 patients who underwent ERCP and found that gastrointestinal obstruction,jaundice,opioid use,female sex,and primary diseases were in-dependent predictors and risk factors of preoperative gastric retention.Based on these findings and comprehensive analysis,a proposed predictive model offers clinicians valuable tools to tailor preoperative strategies,improving the proce-dural safety and efficacy of ERCP.Despite having several limitations,like single-center design and limited generalizability,the study marks a significant advan-cement in optimizing ERCP outcomes through predictive analytics.Further research with larger populations and prospective designs is warranted to establish these findings.
文摘Objective: To assess the impact of preoperative psychological interventions on the care of patients undergoing elective surgery. Methods: Ninety-two patients scheduled for elective surgery in the surgical department between August 2021 and August 2023 were selected and divided into groups using a random number table. The observation group received preoperative psychological interventions, while the reference group received standard preoperative care. Anxiety and depression scores, fear grading, vital signs, and self-efficacy levels were compared. Results: After the intervention, the anxiety and depression scores in the observation group were lower than those in the reference group, and the proportion of fear graded as Level I was higher. During the waiting period and 15 minutes before entering the operating room, vital sign levels in the observation group were lower than those in the reference group. Additionally, the self-efficacy scores of the observation group were significantly higher than those of the reference group (P < 0.05). Conclusion: Preoperative psychological interventions can alleviate negative emotions, stabilize preoperative vital signs, and significantly improve self-efficacy in patients undergoing elective surgery, demonstrating high feasibility for implementation.
文摘Objective:Pediatric patients undergoing day surgery often experience significant anxiety,which can negatively impact both the child and their parents.Addressing this anxiety is crucial to ensure a smooth surgical experience and recovery.This mini review aims to evaluate the impact of preoperative anxiety in children,identify contributing factors,and explore effective strategies to manage this anxiety during day surgery.Methods:A literature review was conducted,focusing on studies that assess anxiety levels in pediatric patients before day surgery and the interventions designed to alleviate this anxiety.The review included both psychological and procedural strategies.Results:Preoperative anxiety in children can be influenced by a variety of factors,including age,previous medical experiences,parental anxiety,and the hospital environment.Untreated anxiety may lead to increased postoperative pain,behavioral changes,and extended recovery times.Several strategies,including psychological preparation,family centered approaches,and the involvement of child life specialists,have been shown to effectively reduce anxiety.Conclusions:Managing anxiety in pediatric day surgery is vital to improving both surgical outcomes and the overall experience for children and their families.Healthcare professionals can play a key role in reducing anxiety through targeted interventions and supportive care.
文摘BACKGROUND Hepatobiliary surgery is complex and requires a thorough understanding of the liver’s anatomy,biliary system,and vasculature.Traditional imaging methods such as computed tomography(CT)and magnetic resonance imaging(MRI),although helpful,fail to provide three-dimensional(3D)relationships of these structures,which are critical for planning and executing complicated surgeries.AIM To explore the use of 3D imaging and virtual surgical planning(VSP)technologies to improve surgical accuracy,reduce complications,and enhance patient recovery in hepatobiliary surgeries.METHODS A comprehensive review of studies published between 2017 and 2024 was conducted through PubMed,Scopus,Google Scholar,and Web of Science.Studies selected focused on 3D imaging and VSP applications in hepatobiliary surgery,assessing surgical precision,complications,and patient outcomes.Thirty studies,including randomized controlled trials,cohort studies,and case reports,were included in the final analysis.RESULTS Various 3D imaging modalities,including multidetector CT,MRI,and 3D rotational angiography,provide high-resolution views of the liver’s vascular and biliary anatomy.VSP allows surgeons to simulate complex surgeries,improving preoperative planning and reducing complications like bleeding and bile leaks.Several studies have demonstrated improved surgical precision,reduced complications,and faster recovery times when 3D imaging and VSP were used in complex surgeries.CONCLUSION 3D imaging and VSP technologies significantly enhance the accuracy and outcomes of hepatobiliary surgeries by providing individualized preoperative planning.While promising,further research,particularly randomized controlled trials,is needed to standardize protocols and evaluate long-term efficacy.

文摘BACKGROUND Although obesity is a well-established contributor to surgical risks,evidence regarding the specific outcomes of laparoscopic cholecystectomy(LC)in obese patients remains scarce.AIM To assess clinicopathologic differences and 1-year outcomes following elective LC in patients with obesity and gallstone disease.METHODS This retrospective study analyzed data from 65 patients who underwent elective LC for gallstone disease between January 2020 and May 2022,with outcomes assessed at the 1-year follow-up.Patients were categorized as obese(body mass index≥25 kg/m^(2))or non-obese(body mass index<25 kg/m^(2)),and comparisons were made across preoperative laboratory values,intraoperative parameters,and patient-reported outcomes.RESULTS The obese group had significantly higher American Society of Anesthesiologists scores,higher glycated hemoglobin levels,and lower vitamin D levels than the non-obese group.Elevated triglycerides were more frequent in the obese group,whereas higher high-density lipoprotein levels were more common in the nonobese group.Intraoperative and postoperative outcomes did not differ between the groups.At the 1-year follow-up,24.6%of patients reported post-cholecystectomy symptoms,with no group differences.CONCLUSION Obese patients had higher American Society of Anesthesiologists scores,lower vitamin D,and elevated triglycerides preoperatively,but these differences did not significantly affect intraoperative findings or 1-year postoperative outcomes compared to non-obese patients.
文摘Zhou et al’s investigation on the creation of a non-invasive deep learning(DL)method for colorectal tumor immune microenvironment evaluation using preoperative computed tomography(CT)radiomics published in the World Journal of Gastrointestinal Oncology is thorough and scientific.The study analyzed preoperative CT images of 315 confirmed colorectal cancer patients,using manual regions of interest to extract DL features.The study developed a DL model using CT images and histopathological images to predict immune-related indicators in colorectal cancer patients.Pathological(tumor-stroma ratio,tumor-infiltrating lymphocytes infiltration,immunohistochemistry,tumor immune microenvir-onment and immune score)parameters and radiomics(CT imaging and model construction)data were combined to generate artificial intelligence-powered models.Clinical benefit and goodness of fit of the models were assessed using receiver operating characteristic,area under curve and decision curve analysis.The developed DL-based radiomics prediction model for non-invasive evaluation of tumor markers demonstrated potential for personalized treatment planning and immunotherapy strategies in colorectal cancer patients.The study,involving a small group from a single medical center,lacks inclusion/exclusion criteria and should include clinicopathological features for valuable therapeutic practice insights in colorectal cancer patients.

文摘BACKGROUND Despite improved survival rates in rectal cancer treatment,many patients experience low anterior resection syndrome(LARS).The preoperative LARS score(POLARS)aims to address the limitations of LARS assessment by predicting outcomes preoperatively to enhance surgical planning.AIM To investigate the predictive accuracy of POLARS in assessing the occurrence of LARS.METHODS This study enrolled a total of 335 patients who underwent laparoscopic or robotic low anal sphincter-preserving surgery for rectal tumors.Patients were categorized into three groups according to their POLARS score:no LARS(score 0-20),minor LARS(score 21-29),and major LARS(score 30-42).The QLQ-C30/CR29 scores were compared among these groups,and the agreement between POLARS predictions and the actual LARS scores was analyzed.RESULTS The study population was divided into three groups:major LARS(n=51,27.42%),minor LARS(n=109,58.6%),and no LARS(n=26,13.98%).Significant differences in the QLQ-C30 scales of social function,diarrhea,and financial impact were detected between the no LARS and major LARS groups(P<0.05)and between the minor LARS and major LARS groups(P<0.05).Similarly,significant differences were detected in the QLQ-CR29 scales for blood and mucus in the stool,fecal incontinence,and stool frequency between the no LARS and minor LARS groups(P<0.05),as well as between the minor LARS and major LARS groups(P<0.05).The predictive precision for major LARS using the POLARS score was 82.35%(42/51),with a recall of 35.89%(42/117).The mean absolute error(MAE)between the POLARS score and the actual LARS score was 8.92±5.47.In contrast,the XGBoost(extreme gradient boosting)model achieved a lower MAE of 6.29±4.77,with a precision of 84.39%and a recall of 74.05%for predicting major LARS.CONCLUSION The POLARS score demonstrated effectiveness and precision in predicting major LARS,thereby providing valuable insights into postoperative symptoms and patient quality of life.However,the XGBoost model exhibited superior performance with a lower MAE and higher recall for predicting major LARS compared to the POLARS model.
文摘BACKGROUND The diagnostic accuracy for detecting metastatic lymph nodes in colorectal cancer(CRC)remains suboptimal.To address this limitation,our study investigates the potential of gemstone spectral computed tomography imaging(GSI)to improve diagnostic accuracy in lymph node metastasis(LNM)assessment.AIM To extensively investigate the clinical utility of GSI in the preoperative assessment of CRC.METHODS The subject population included 200 patients with CRC who were admitted to Zibo Central Hospital from January 2022 to December 2023.All patients underwent dual-phase contrast-enhanced scans in the arterial and venous phases using GSI before surgical intervention.During the research,meticulous quantification was conducted regarding the number of patients with CRC with LNM as well as the exact count of metastatic lymph nodes.Moreover,for both metastatic and non-metastatic lymph nodes,the short diameter at the maximum crosssectional area(covering the axial,sagittal,and coronal planes),morphological features(including manifestations such as margin blurring,aggregation,and enhancement),and spectral parameters in the arterial and venous phases[specifically iodine concentration(IC),normalized IC(NIC),and the slope of the spectral curve(λHU)]were measured and recorded,and a comparative analysis was conducted.The diagnostic efficacy of each index with differences was systematically assessed using the receiver operating characteristic(ROC)curve.Concurrently,receiver operating characteristic curves were constructed for LNM screening based on the short diameter at the maximum cross-sectional area of lymph nodes and each spectral parameter in the arterial and venous phases.RESULTS The area under the curve of GSI for diagnosing LNM in patients with CRC can reach 0.897,with sensitivity,specificity,and accuracy of 92.59%,85.87%,and 89.50%,respectively.A total of 265 lymph nodes were analyzed from the 200 participants with CRC,with metastatic lymph nodes accounting for 56.60%.Compared with nonmetastatic lymph nodes,the short diameters of metastatic lymph nodes in the axial,sagittal,and coronal planes were significantly increased,whereas the IC values in the arterial and venous phases,the NIC value in the arterial phase,and theλHU values in the arterial and venous phases were significantly decreased.The short axial,sagittal,and coronal diameters,arterial-phase IC,venous-phase IC,arterial-phase NIC,arterial-phaseλHU,and venousphaseλHU for diagnosing metastatic lymph nodes demonstrated area under the curve values of 0.631,0.681,0.659,0.862,0.808,0.831,0.801,and 0.706,respectively.CONCLUSION GSI exhibits substantial clinical significance in the preoperative assessment of CRC.Among the parameters assessed,the arterial-phase IC demonstrates the most outstanding diagnostic performance,effectively improving the diagnostic efficacy for preoperative LNM in CRC.
文摘BACKGROUND Total hip arthroplasty(THA)is an increasingly common treatment for older patients with hip osteoarthritis.Psychological stress is common before THA,although its clinical effects on selected parameters such as joint function,quality of life,and postoperative complications remain unclear.AIM To investigate the effects of preoperative psychological stress on selected parameters in older patients who underwent THA.METHODS Ninety older patients who underwent THA between January 2023 and August 2024 were divided into two groups by their preoperative self-rated anxiety scale and self-rated depression scale scores,including high-stress(n=42)and lowstress(n=48).The postoperative joint function,short form-36 health survey(SF36)score,incidence of postoperative complications,and other indicators were compared between the two groups.Pearson’s correlation coefficient analysis of the relationship among preoperative psychological stress,quality of life,and postoperative complications was performed.RESULTS Postoperative joint function and quality of life were lower in the high-stress group than they were in the low-stress group(P<0.05).The incidence of postoperative complications was higher in the high-stress group(29.27%)than it was in the low-stress group(9.30%)(P<0.05).Cor-relation analysis revealed that psychological stress was correlated with the Harris hip and SF-36 scores.Total scores on the scale,including physical function,physical pain,general health,mental health,social function,vitality,and emotional function,were negatively correlated(P<0.05).CONCLUSION Preoperative psychological stress results in adverse effects on quality of life and complications in older patients undergoing THA.Therefore,pre-operative psychological interventions should be strengthened to improve postoperative outcomes.
