There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The investigators retrospectively collected the participants with T3 and T4, N0-2, M0 NSCLC patients resected between January 2013 to December 2021 for training and internal validation. The Clinical data, preoperative laboratory results and images were collected. High-risk margins were defined as R1 or R2 surgical margins or local recurrence during follow-up, and the investigators also collected the disease-free survival time. On the Deepwise multi-modal research platform, the images were semi-automatically segmented and expanded outward by 3mm to obtain the peritumor tissue. PyRadiomics was used to extract the radiomic features. LASSO was used to select the features and tumor radiomics model, peritumor model and combined model were built using 5-fold cross-validation. And it was further tested on the independent cohort. Discrimination was assessed by using the C-index and area under the receiver operating characteristic curve (AUC), sensibility, specificity.
Fever is a common clinical symptom in patients with postoperative scoliosis. However, there are rare reports of immediately fevers occurring following operative procedures.
A retrospective cohort study, conducted nationwide（China） and across multiple centers, aimed to compare the surgical quality and short-term outcomes of R-NOSES （robotic natural orifice specimen extraction surgery）with R-TSES （robotic transabdominal specimen extraction surgery） for early-stage rectal cancer.
Evaluating the value of dynamic monitoring of a colorectal cancer liver metastasis cohort underwent curative resection after receiving multipoint ctDNA detecting in predicting recurrence prognosis and guiding adjuvant chemotherapy treatment.
Between March 2019 and September 2022 in our centre, R anastomosis was performed on 123 patients undergoing TLDG for distal gastric cancer. A retrospective review of a prospectively collected database identified patients who underwent TLDG between January 2010 and September 2022. Patients who underwent R anastomosis were matched in a 1:1 ratio with patients who underwent conventional anastomosis using a propensity score based on age, sex, preoperative BMI, American Society of Anesthesiologists (ASA) score, and the history of abdominal surgery. Surgical and postoperative outcomes and clinicopathological data were analyzed for both groups.
Background: Anastomotic stricture significantly impacts patients' quality of life and long-term prognosis. However, current clinical practice lacks accurate tools for predicting anastomotic stricture. This study aimed to develop a nomogram to predict anastomotic stricture in patients with rectal cancer who have undergone anterior resection. Methods: 1542 eligible patients will be recruited for the study. Least absolute shrinkage selection operator (Lasso) analysis will be used to preliminarily select predictors. A prediction model will be constructed using multivariate logistic regression and presented as a nomogram. The performance of the nomogram will be evaluated using receiver operating characteristic (ROC) curves, calibration diagrams, and decision curve analysis (DCA). Internal validation will be conducted by assessing the model's performance on a validation cohort.
As defined by sepsis 3.0, sepsis is a clinical syndrome caused by disordered host response to serious infection，leading to multiple organ dysfunction1. Sepsis-associated liver dysfunction (SALD) is one of the most frequently complication in sepsis, possessing high morbidity and mortality2. A close relationship exists between the gut and the liver, and their bidirectional interaction was commonly known as the 'gut-liver' axis3. Systemic inflammation and hypoperfusion play a crucial role in the pathophysiological processes of acute gastrointestinal injury (AGI) in sepsis4. The translocation of bacteria and toxins due to gut barrier injury during AGI can promote the entry of bacteria and their products into the liver through the portal circulation and lymphatic system, leading to the occurrence of SALD. Our previous study found that septic patients with abdominal infections and SALD suffered a higher incidence of AGI when compared with patients without SALD5. Faecal calprotectin (FC) is a convenient, non-invasive biomarker that has a good correlation with gut inflammation6. The FC concentration is proportional to neutrophil migration to the gut and correlates well with fecal leukocyte excretion7. Study found that FC concentrations were significantly higher in septic patients complicated with AGI than those without, and it can be used as an early indicator for the diagnosis of AGI8. However, the relationship between FC concentration and SALD in septic patient is unclear. We conducted a prospective study to explore the potential association between FC concentration and SALD in septic patients. The dynamic changes in the FC concentration from day 1 to 3 after enrollment were also investigated.
In order to determine the abnormal cerebral metabolism in the pathological state, we compared the blood of internal jugular vein, superior vena cava and radial artery during central venous catheterization. Metabonomics, proteomics and inflammatory factor microarray were used to detect the material differences in arteriovenous blood of patients with disorders of consciousness. At the same time, we concurrently compared it with the peripheral plasma metabolome of two additional patient cohorts: those in-stent restenosis and non-restenosis.
Primary Purpose: The primary purpose of this study is to evaluate the effectiveness of the Yannianjiuzhuan method combined with reverse abdominal breathing in improving symptoms of constipation, anxiety, sleep quality, and overall quality of life in elderly patients with coronary heart disease and constipation. Study Phase: As this research involves a non-pharmacological intervention, it is categorized as Not Applicable (N/A). Intervention Model: Parallel Assignment. Patients are divided into two groups; one receives standard care, while the other receives standard care supplemented by the Yannianjiuzhuan method combined with reverse abdominal breathing. Number of Arms: Two arms are involved in the study. One arm serves as the control group receiving standard care, and the other as the experimental group receiving standard care plus the Yannianjiuzhuan method combined with reverse abdominal breathing. Masking: This study employed a double-blind (assessors and statisticians), randomized, parallel-controlled trial design to enhance the credibility of the results and to minimize bias. Allocation: Using simple random sampling, small folded papers marked with the numbers "1" and "2" were placed in an opaque box. Each patient drew a paper in sequence of enrollment; those drawing a "1" were assigned to the control group, and those drawing a "2" to the experimental group, with each group comprising 35 participants. Enrollment: A total of 70 patients were initially recruited, with 67 completing the study. The control group had one participant drop out due to early hospital discharge related to the pandemic, affecting data collection completeness. In the experimental group, one participant was excluded due to undergoing colonoscopy and taking related laxative medications during the treatment, and another due to early hospital discharge caused by the pandemic. Thus, data from three participants were excluded from the final analysis due to insufficient treatment duration (less than two-thirds of the planned intervention), resulting in 34 participants in the control group and 33 in the experimental group being analyzed, equating to a dropout rate of approximately 4.3%, which is within acceptable statistical limits. Study Classification: This study focuses on efficacy assessment. It particularly evaluates the effectiveness of the Yannianjiuzhuan method combined with reverse abdominal breathing in alleviating symptoms of constipation, anxiety, improving sleep quality, and enhancing the quality of life among elderly patients with coronary heart disease and constipation.
After ultrasound-indicated cerclage, some pregnant women still experience sPTB, and there is controversy regarding the use of tocolytic agents during the perioperative period to reduce the incidence of sPTB. In this study, the investigators employed a randomized double-blind method to investigate whether the use of atosiban during the perioperative period can reduce the incidence of sPTB before 34 weeks.
