Deep brain stimulation (DBS) surgery is an important treatment for patients with Parkinson's disease in the middle and late stages. The accuracy of the implantation of electrode at the location of the nuclei directly determines the therapeutic effect of the operation. At present, there is no single imaging method that can obtain images with electrodes, nuclei and their positional relationship. In addition, the subthalamic nucleus is small in size and the boundary is not obvious, so it cannot be directly segmented. In this paper, a complete end-to-end DBS effect evaluation pipeline was constructed using magnetic resonance (MR) data of T1, T2 and SWI weighted by DBS surgery. Firstly, the images of preoperative and postoperative patients are registered and normalized to the same coordinate space. Secondly, the patient map is obtained by non-rigid registration of brain map and preoperative data, as well as the preoperative nuclear cluster prediction position. Then, a three-dimensional (3D) image of the positional relationship between the electrode and the nucleus is obtained by using the electrode path in the postoperative image and the result of the nuclear segmentation. The 3D image is helpful for the evaluation of the postoperative effect of DBS and provides effective information for postoperative program control. After analysis, the algorithm can achieve a good registration between the patient's DBS surgical image and the brain map. The error between the algorithm and the expert evaluation of the physical coordinates of the center of the thalamus is (1.590 ± 1.063) mm. The problem of postoperative evaluation of the placement of DBS surgical electrodes is solved.
ObjectiveTo summarize the research status and new directions of surgical treatment of hepatic alveolar echinococcosis (HAE) in clinic, and to provide reference for further research in improving the rate of radical surgery.MethodThe recent literatures on the studies of HAE were reviewed.ResultsAlthough the biological behavior of HAE was similar to that of malignant tumor, the clinical symptoms appeared late as the intrahepatic lesions often grow slowly. At present, the treatment of this disease was mainly surgical operation, among which radical resection was the first choice. Drug therapy was also of great value in controlling disease progression and recurrence. In recent years, with the progress of surgical technology, the surgical method had gradually developed to the direction of multi-mode combination, especially for those cases that had not been able to perform conventional radical surgery before.ConclusionThe treatment concept of clinical multi-mode combination can benefit more patients, even achieve clinical radical resection, and improve the rate of radical resection.
ObjectiveTo explore the effect of standardized multimodal analgesia (SMA) on opioid consumption after major upper abdominal surgery under enhanced recovery after surgery pathway. MethodsPatients who underwent major upper abdominal surgery in the West China Hospital of Sichuan University between August and November 2020 were included prospectively. The patients were divided into two groups: SMA group (n=175) and control group (n=632). The SMA was defined as preoperative and postoperative use of non-steroidal anti-inflammatory drugs, combined with regional anesthesia, local anesthetic wound infiltration or intrathecal opioid. The postoperative opioid consumption in oral morphine equivalents, the pain scores on movement and at rest, the postoperative rehabilitation were recorded and compared between the two groups. ResultsPatients in the SMA group had a lower opioid consumption during the first 72 h compared to patients in the control group (median: 51 mg vs. 85 mg, P<0.001). The pain scores on movement and at rest at 24, 48, 72 h after surgery in the SMA group were lower than those in the control group (P<0.05). Time to first flatus, time to first ambulation, postoperative hospital stay in the SMA group were significantly shorter than those in the control group (P<0.05), and the quality of life scores at 5 d after surgery increased significantly (P<0.05). The satisfaction with analgesia and the incidence of adverse effects on day 5 after surgery had no statistical significances between the two groups (P>0.05). After controlling for confounding factors, multiple linear regression analysis showed that SMA was associated with less opioid consumption on hour 72 after surgery (P<0.001). ConclusionSMA can reduce postoperative opioid consumption in patients undergoing major upper abdominal surgery.
In 2020, the American Association of Hip and Knee Surgeons (AAHKS), the American Society of Regional Anesthesia and Pain Medicine (ASRA), the American Academy of Orthopaedic Surgeons (AAOS), the American Hip Society (THS), the American Knee Society (TKS) have worked together to develop clinical practice guidelines on the use of Opioids in primary total joint arthroplasty (TJA). This clinical practice guideline formulates recommendations for common and important questions related to the efficacy and safety of Opioids in primary TJA. This article interprets the guideline to help doctors make clinical decisions.
This review systematically analyzes recent research progress in multimodal fusion techniques for medical imaging classification, focusing on various fusion strategies and their effectiveness in classification tasks. Studies indicate that multimodal fusion methods significantly enhance classification performance and demonstrate potential in clinical decision support. However, challenges remain, including insufficient dataset sharing, limited utilization of text modalities, and inadequate integration of fusion strategies with medical knowledge. Future efforts should focus on developing large-scale public datasets and optimizing deep fusion strategies for image and text modalities to promote broader application in medical scenarios.
Objective To explore the effect of multimodal interventions in improving the compliance rate of core infection control measures on reducing the incidence rate of vessel catheter associated infection (VCAI). Methods Inpatients with intravascular catheters in 5 departments with high rates of vascular catheterization and infection of Dongguan People’s Hospital between January 2021 and December 2022 were selected. According to the hospital stay, patients were divided into a pre-intervention group (January to December 2021) and a post-intervention group (January to December 2022). The core infection control measures assessment pass rates of medical staff between the two periods and the differences in the incidence rate of VCAI, average catheterization days, and catheterization rate before and after intervention in both groups were compared. Results A total of 8174 patients were included. Among them, there were 3915 patients in the pre-intervention group and 4259 patients in the post-intervention group. In the pre-intervention group, the total length of hospital stay was 122885 days, the total number of catheterization days was 48028 days, and 28 cases of VCAI occurred. In the post-intervention group, the total length of hospital stay was 126966 days, the total number of catheterization days was 51253 days, and 12 cases of VCAI occurred. After intervention, the compliance rate of VCAI core infection control measures was improved [69.21% (2907/4200) vs. 91.24% (3832/4200); χ2=642.090, P＜0.001], the pass rate of medical staff’s core infection control measures assessment was improved [53.33% (128/240) vs. 91.67% (220/240); χ2=88.443, P＜0.001], the catheterization rate was increased [39.08% (48028/122885) vs. 40.37% (51253/126966); χ2=42.979, P<0.001], and the incidence rate of VCAI was reduced [0.58‰ (28/48028) vs. 0.23‰ (12/51253); incidence-rate ratios =0.40, 95% confidence interval (0.20, 0.79), P=0.008]. Conclusions Improving the compliance rate of VCAI core infection control measures through multimodal interventions can significantly improve the passing rates of core infection control measures of medical staffs. This will help to reduce the incidence of VCAI and ensuring patient safety, provide evidence-based support for the prevention and control of VCAI.

Objective To understand the incidence and severity of postoperative acute pain in patients undergoing day surgery, and to explore the influencing factors of moderate to severe pain after surgery, so as to provide a reference for pain management in day surgery. Methods Convenience sampling method was used to select patients undergoing day surgery under multi-modal pain management in West China Hospital of Sichuan University between April and August 2020, and the general conditions, surgical conditions, and postoperative pain of the patients were investigated. According to the degree of postoperative pain, patients were divided into mild pain group and moderate to severe pain group. Logistic regression analysis was used to explore the influencing factors of postoperative pain in the two groups. Results A total of 509 patients were finally included, of which 69 patients presented with moderate to severe pain. Logistic regression analysis showed that patient age [odds ratio (OR)=0.970, 95% confidence interval (CI) (0.946, 0.993), P=0.012], pain threshold [OR=1.348, 95%CI (1.048, 1.734), P=0.020] and postoperative drainage tube [OR=2.752, 95%CI (1.090, 6.938), P=0.017] were the influencing factors of moderate to severe pain after surgery. Conclusion Under multimodal pain management, the incidence of moderate to severe pain in day surgery patients is low, and medical staff should further strengthen pain management from the factors affecting pain to reduce the incidence of moderate to severe pain after surgery.
ObjectiveTo review the advances in perioperative pain management of pediatric and adolescent spinal deformity corrective surgery.MethodsRegular analgesics, drug administrations, and analgesic regimens were reviewed and summarized by consulting domestic and overseas related literatures about perioperative pain management of pediatric and adolescent spinal deformity corrective surgery in recent years.ResultsAs for perioperative analgesis regimens of pediatric and adolescent spinal deformity corrective surgery, regular analgesics include non-steroidal anti-inflammatory drugs, opioids, antiepileptic drugs, adrenergic agonists, and local anesthetic, etc. Besides drug administration by mouth, intravenous injection, and intramuscular injection, the administration also includes patient controlled analgesia, epidural injection, and intrathecal injection. Multimodal analgesia is the most important regimen currently.ConclusionHeretofore, a number of perioperative pain managements of pediatric and adolescent spinal deformity corrective surgery have been applied clinically, but the ideal regimen has not been developed. To design a safe and effective analgesic regimen needs further investigations.
China is facing the double burden of high incidence of lung cancer and tuberculosis epidemic. Lung cancer combined with tuberculosis has a high incidence and complexity in clinical practice. High-risk groups include immunocompromised people, long-term smokers and people with a history of tuberculosis. The coexistence of the two diseases not only increases the difficulty of diagnosis and treatment decision-making, but also increases the risk of treatment-related adverse reactions and drug interactions. The guideline was developed by Committee of Integrated Rehabilitation for Lung Cancer, Chinese Anti-Cancer Association; Chinese and Western Integrated Lung Cancer Committee of Chinese Anti-Cancer Association; Society of Tuberculosis, Chinese Medical Association, aiming to standardize the diagnosis and treatment of lung cancer complicated with pulmonary tuberculosis. The guideline emphasizes the core position of combined diagnosis of multimodal imaging, etiology and pathology. It is proposed that anti-tuberculosis and anti-tumor treatment should be coordinated under the framework of multidisciplinary team, and drug interactions and timing optimization should be paid attention to. For surgical treatment, minimally invasive resection combined with systematic lymph node dissection is recommended after infection control. Systemic therapy requires individualized risk stratification and dynamic monitoring of efficacy and adverse reactions. Based on evidence-based medicine and Chinese clinical practice, combined with the accessibility of drugs and technologies, this guideline proposes a whole-process management pathway covering screening, diagnosis, treatment and follow-up, in order to improve the prognosis and quality of life of patients.
