With the rapid expansion of social media,analyzing emotions and their causes in texts has gained significant importance.Emotion-cause pair extraction enables the identification of causal relationships between emotions and their triggers within a text,facilitating a deeper understanding of expressed sentiments and their underlying reasons.This comprehension is crucial for making informed strategic decisions in various business and societal contexts.However,recent research approaches employing multi-task learning frameworks for modeling often face challenges such as the inability to simultaneouslymodel extracted features and their interactions,or inconsistencies in label prediction between emotion-cause pair extraction and independent assistant tasks like emotion and cause extraction.To address these issues,this study proposes an emotion-cause pair extraction methodology that incorporates joint feature encoding and task alignment mechanisms.The model consists of two primary components:First,joint feature encoding simultaneously generates features for emotion-cause pairs and clauses,enhancing feature interactions between emotion clauses,cause clauses,and emotion-cause pairs.Second,the task alignment technique is applied to reduce the labeling distance between emotion-cause pair extraction and the two assistant tasks,capturing deep semantic information interactions among tasks.The proposed method is evaluated on a Chinese benchmark corpus using 10-fold cross-validation,assessing key performance metrics such as precision,recall,and F1 score.Experimental results demonstrate that the model achieves an F1 score of 76.05%,surpassing the state-of-the-art by 1.03%.The proposed model exhibits significant improvements in emotion-cause pair extraction(ECPE)and cause extraction(CE)compared to existing methods,validating its effectiveness.This research introduces a novel approach based on joint feature encoding and task alignment mechanisms,contributing to advancements in emotion-cause pair extraction.However,the study’s limitation lies in the data sources,potentially restricting the generalizability of the findings. 展开更多

Pulmonary embolism(PE)is a rare but devastating complication of shoulder surgery.Apart from increased morbidity and mortality rates,it may significantly impair postoperative recovery and functional outcome.Its frequency accounts for up to 5.7%of all shoulder surgery procedures with a higher occurrence in women and patients older than 70 years.It is most commonly associated with thrombophilia,diabetes mellitus,obesity,smoking,hypertension,and a history of malignancy.PE usually occurs secondary to upper or lower-extremity deep vein thrombosis(DVT).However,in rare cases,the source of the thrombi cannot be determined.Prophylaxis for PE following shoulder surgery remains a topic of debate,and the standard of care does not routinely require prophylactic medication for DVT prophylaxis.Early ambulation and elastic stockings are important preventative measures for DVT of the lower extremity and medical agents such as aspirin,low-molecular-weight heparin,and vitamin K antagonists are indicated for high-risk patients,long-lasting operations,or concomitant severe acute respiratory syndrome coronavirus 2 infection.The most common symptoms of PE include chest pain and shortness of breath,but PE can also be asymptomatic in patients with intrinsic tolerance of hypoxia.Patients with DVT may also present with swelling and pain of the respective extremity.The treatment of PE includes inpatient or outpatient anticoagulant therapy if the patient is hemodynamically unstable or stable,respectively.Hemodynamic instability may require transfer to the intensive care unit,and cardiovascular arrest can be implicated in fatal events.An important issue for patients with PE in the postoperative period after shoulder surgery is residual stiffness due to a delay in rehabilitation and a prolonged hospital stay.Early physiotherapy and range-of-motion exercises do not adversely affect the prognosis of PE and are highly recommended to preserve shoulder mobility and function. 展开更多

AIM To investigate a comprehensive range of factors that contribute to long-term patient satisfaction post-total joint replacement(TJR) in people who had undergone knee or hip replacement for osteoarthritis.METHODS Participants(n = 1151) were recruited from Nottinghamshire post-total hip or knee replacement. Questionnaire assessment included medication use, the pain-DETECT questionnaire(PDQ) to assess neuropathic pain-like symptoms(NP) and TJR satisfaction measured on average 4.8 years post-TJR. Individual factors were tested for an association with post-TJR satisfaction, before incorporating all factors into a full model. Data reduction was carried out using LASSO and receiveroperator characteristic(ROC) curve analysis was used to quantify the contribution of variables to post-TJR satisfaction.RESULTS After data reduction, the best fitting model for post-TJR satisfaction included various measures of pain, history of revision surgery, smoking, pre-surgical X-ray severity, WOMAC function scores and various comorbidities. ROC analysis of this model gave AUC = 0.83(95%CI: 0.80-0.85). PDQ scores were found to capture much of the variation in post-TJR satisfaction outcomes: AUC = 0.79(0.75-0.82). Pre-surgical radiographic severity was associated with higher post-TJR satisfaction: OR_(satisfied) = 2.06(95%CI: 1.15-3.69), P = 0.015.CONCLUSION These results highlight the importance of pre-surgical radiographic severity, post-TJR function, analgesic medication use and NP in terms of post-TJR satisfaction. The PDQ appears to be a useful tool in capturing factors that contribute to post-TJR satisfaction. 展开更多

OBJECTIVE: To explore the effects of traditional Chinese medicine(TCM) five-element music combined with acupoint application on perioperative sleep quality in patients undergoing joint replacement surgery. METHODS: In this study, a total of 122 patients with joint replacement surgery in Beijing Jishuitan Hospital were targeted from 2015 to 2018. All patients were grouped by random number table method. Among them, 61 patients with routine nursing were included in the control group. On this basis, the other 61 patients with acupoint application and TCM five-element music therapy were included as the observation group. 2 weeks later, the Pittsburgh Sleep Quality Index(PSQI) was used to evaluate sleep quality in all patients. The sleep improvement of the 2 groups was evaluated, and the patient was assessed for anxiety and depression, and the curative efficacy was evaluated. RESULTS: After 2 weeks of nursing, the PSQI of the patients improved significantly. The PSQI of the observation group was only 6.6 ± 2.4, and the control group decreased to 9.9 ± 2.7. The observation group was better than the control group, and the difference was statistically significant(P < 0.05). Comparing the 2 groups, the anxiety score of the observation group decreased to 4.8 ± 1.6, which was significantly lower than that of 6.9 ± 2.2 in the control group. The depression score of the observation group decreased to 4.6 ± 1.3, which was significantly lower than that of 6.8 ± 2.3 in the control group. In the control group, the negative emotion scores after nursing were better than those before nursing, and the difference was statistically significant(P < 0.05). Comparing the 2 groups, the effective rate of sleep improvement in the observation group was 96.6%, and the cure rate was as high as 49.1%. The control group was 82.0%, and the cure rate was 18.0%. The observation group was better than the control group, and the difference was statistically significant(P < 0.05). CONCLUSION: The combination of TCM five-element music with acupoint application can improve the perioperative sleep quality of patients undergoing joint replacement surgery, and it can help patients to relieve negative emotions. It is worth promoting. 展开更多

The top goal of modern medicine is treating disease without destroying organ structures and making patients as healthy as they were before their sickness.Minimally invasive surgery(MIS)has dominated the surgical realm because of its lesser invasiveness.However,changes in anatomical structures of the body and reconstruction of internal organs or different organs are common after traditional surgery or MIS,decreasing the quality of life of patients post-operation.Thus,I propose a new treatment mode,super MIS(SMIS),which is defined as“curing a disease or lesion which used to be treated by MIS while preserving the integrity of the organs”.In this study,I describe the origin,definition,operative channels,advantages,and future perspectives of SMIS. 展开更多

Objective: To assess the effect of fast track surgery care on knee joint function in patients with knee joint replacement surgery. Methods: Eighteen databases were searched for randomized controlled trials, focusing on evaluation of fast track surgery care on knee joint function in patients with knee joint replacement surgery. Two people independently screened literatures and extracted data according to the inclusion criteria. Then the available data were analyzed with RevMan software (version 5.3.0). Descriptive techniques were performed when no available data could be used. Results: A total of 8 studies were included, for a total sample of 635 patients. The results showed that fast track surgery care can improve Hospital for Special Surgery Knee score at 2 months, 3 months, 6 months, and 1 years after operation [after 2 months (weighted mean difference (WMD), 15.2;95%CI, 13.58 to 16.82;P < 0.01);after 3 months (WMD, 9.42;95%CI, 7.80 to 11.04;P < 0.01);after 6 months,(WMD, 11.01;95%CI, 9.73 to 12.28;P < 0.01);after 1 years (WMD, 10.78;95%CI, 9.33 to 12.24;P < 0.01)]. Fast track surgery care can improve the knee score of American Knee Society Knee Score(WMD, 9.23;95%CI,0.86 - 17.6;P < 0.05), and reduce the incidence of postoperative deep vein thrombosis, constipation, pulmonary infection, urinary tract infection and other complications. Conclusion: Fast track surgery care can promote knee joint function recovery, reduce postoperative deep venous thrombosis, constipation, pulmonary infection and urinary tract infection. However, rigorous large sample and multicenter randomized controlled trials are needed for further validation. 展开更多

Introduction: Ultrafast latest developments in artificial intelligence (ΑΙ) have recently multiplied concerns regarding the future of robotic autonomy in surgery. However, the literature on the topic is still scarce. Aim: To test a novel AI commercially available tool for image analysis on a series of laparoscopic scenes. Methods: The research tools included OPENAI CHATGPT 4.0 with its corresponding image recognition plugin which was fed with a list of 100 laparoscopic selected snapshots from common surgical procedures. In order to score reliability of received responses from image-recognition bot, two corresponding scales were developed ranging from 0 - 5. The set of images was divided into two groups: unlabeled (Group A) and labeled (Group B), and according to the type of surgical procedure or image resolution. Results: AI was able to recognize correctly the context of surgical-related images in 97% of its reports. For the labeled surgical pictures, the image-processing bot scored 3.95/5 (79%), whilst for the unlabeled, it scored 2.905/5 (58.1%). Phases of the procedure were commented in detail, after all successful interpretations. With rates 4 - 5/5, the chatbot was able to talk in detail about the indications, contraindications, stages, instrumentation, complications and outcome rates of the operation discussed. Conclusion: Interaction between surgeon and chatbot appears to be an interesting frontend for further research by clinicians in parallel with evolution of its complex underlying infrastructure. In this early phase of using artificial intelligence for image recognition in surgery, no safe conclusions can be drawn by small cohorts with commercially available software. Further development of medically-oriented AI software and clinical world awareness are expected to bring fruitful information on the topic in the years to come. 展开更多

BACKGROUND We report a case of uterine artery pseudoaneurysm(UAP)occurrence during hysteroscopic endometrial polypectomy and its treatment via uterine artery embolization(UAE).CASE SUMMARY A 48-year-old primigravid,primiparous patient was incidentally found to have an endometrial polyp during a health checkup,and underwent a hysteroscopic polypectomy at another hospital.Her cervix was dilated with a Laminken-R®device.After the Laminken-R®was withdrawn,a large amount of genital bleeding was observed.This bleeding persisted after the hysteroscopic polypectomy,and,as hemostasis became impossible,the patient was transferred to our hospital by ambulance.On arrival,transvaginal ultrasonography revealed a 3-cm hypoechoic mass with a swirling internal pulse on the right side of the uterus,and color Doppler ultrasonography showed feeder vessels penetrating the mass.Pelvic contrast-enhanced computed tomography(CT)confirmed the presence of a mass at this site,and vascular proliferation was observed within the uterine cavity.Consequently,UAP was diagnosed,and UAE was performed.The patient’s postoperative course was uneventful,and 6 mo post-UAE,no recurrence of blood flow to the UAP was observed.CONCLUSION When abnormal genital bleeding occurs during hysteroscopic surgery,ultrasonography and contrast-enhanced CT can assist in the detection of early UAPs. 展开更多

BACKGROUND This study aimed to evaluate the safety of enhanced recovery after surgery(ERAS)in elderly patients with gastric cancer(GC).AIM To evaluate the safety of ERAS in elderly patients with GC.METHODS The PubMed,EMBASE,and Cochrane Library databases were used to search for eligible studies from inception to April 1,2023.The mean difference(MD),odds ratio(OR)and 95%confidence interval(95%CI)were pooled for analysis.The quality of the included studies was evaluated using the Newcastle-Ottawa Scale scores.We used Stata(V.16.0)software for data analysis.RESULTS This study consists of six studies involving 878 elderly patients.By analyzing the clinical outcomes,we found that the ERAS group had shorter postoperative hospital stays(MD=-0.51,I2=0.00%,95%CI=-0.72 to-0.30,P=0.00);earlier times to first flatus(defecation;MD=-0.30,I²=0.00%,95%CI=-0.55 to-0.06,P=0.02);less intestinal obstruction(OR=3.24,I2=0.00%,95%CI=1.07 to 9.78,P=0.04);less nausea and vomiting(OR=4.07,I2=0.00%,95%CI=1.29 to 12.84,P=0.02);and less gastric retention(OR=5.69,I2=2.46%,95%CI=2.00 to 16.20,P=0.00).Our results showed that the conventional group had a greater mortality rate than the ERAS group(OR=0.24,I2=0.00%,95%CI=0.07 to 0.84,P=0.03).However,there was no statistically significant difference in major complications between the ERAS group and the conventional group(OR=0.67,I2=0.00%,95%CI=0.38 to 1.18,P=0.16).CONCLUSION Compared to those with conventional recovery,elderly GC patients who received the ERAS protocol after surgery had a lower risk of mortality. 展开更多

Some rock joints exhibit significant brittleness,characterized by a sharp decrease in shear stress upon reaching the peak strength.However,existing models often fail to accurately represent this behavior and are encumbered by numerous parameters lacking clear mechanical significance.This study presents a new statistical damage constitutive model rooted in both damage mechanics and statistics,containing only three model parameters.The proposed model encompasses all stages of joint shearing,including the compaction stage,linear stage,plastic yielding stage,drop stage,strain softening stage,and residual strength stage.To derive the analytical expression of the constitutive model,three boundary conditions are introduced.Experimental data from both natural and artificial rock joints is utilized to validate the model,resulting in average absolute relative errors ranging from 3%to 8%.Moreover,a comparative analysis with established models illustrates that the proposed model captures stress drop and post-peak strain softening more effectively,with model parameters possessing clearer mechanical interpretations.Furthermore,parameter analysis is conducted to investigate the impacts of model parameters on the curves and unveil the relationship between these parameters and the mechanical properties of rock joints.Importantly,the proposed model is straightforward in form,and all model parameters can be obtained from direct shear tests,thus facilitating the utilization in numerical simulations. 展开更多
