Objectives:To evaluate the clinical efficacies of robot-assisted versus C-arm fluoroscopy-guided percutaneous pedicle screw fixation for thoracolumbar burst fractures.Methods:A retrospective analysis was conducted on 46 patients(26 males,20 females;age 27-69 years)with thoracolumbar burst fractures treated between January 2022 and December 2023.The patients were divided into the observation group of 21 cases(12 males,9 females;52.1±8.8 years)receiving robot-assisted navigation,and the control group of 25 cases(14 males,11 females;50.9±13.2 years)undergoing conventional C-arm fluoroscopy guidance.No significant differences were observed in baseline characteristics(case number,sex ratio,BMI;P＞0.05).Both groups of patients underwent percutaneous pedicle screw internal fixation of the injured vertebra.Intraoperative parameters(fluoroscopy frequency,operative time,blood loss),postoperative CT scans on 3d(assessed by Gertzbein-Robbins scale for screw placement accuracy),pre-and postoperative pain VAS scores(thoracolumbar back pain before surgery and at 1d,3d,and 1 month after surgery),and radiographic parameters(Cobb angle,anterior vertebral body height ratio at preoperation,and postoperative 3d,1 month,and 6 months)were recorded and compared using t-tests and Mann-Whitney U tests.Results:The observation group demonstrated significantly shorter operative time(90.71±9.52min vs 117.62±16.63min,P＜0.05),reduced blood loss(67.14±18.75mL vs 139.52±28.01mL,P＜0.05),and fewer fluoroscopy exposures(9.14±2.27 vs 18.86±2.86,P＜0.05)than the control group.No complications occurred during follow-up in both groups.The observation group exhibited superior screw placement accuracy(98.4％vs 90.7％,P＜0.05)with 124/126 screws graded as excellent/good versus 136/150 in controls.Postoperative pain VAS scores were lower in the observation group on 1d(2.67±0.57 vs 4.00±0.70,P＜0.05)and 3d(1.19±0.68 vs 1.95±0.59,P＜0.05),but comparable at 1 month(0.76±0.43 vs 1.10±0.53,P＞0.05).The postoperative 3d,1 month and 6 months'Cobb angles(6.08°±1.49° vs 6.09°±1.05°,6.26°±1.46° vs 6.28°±1.14°,6.78°±1.38° vs 6.91°±1.31°)and anterior vertebral height ratios[(90.14±1.56)％vs(90.06±1.69)％,(89.62±1.56)％vs(89.44±2.12)％,(88.87±1.72)％vs(88.92±1.88)％]showed no significant in-tergroup differences at different time points(P＞0.05).Conclusions:Robot-assisted percutaneous pedicle screw fixation for the treatment of thoracolumbar burst fractures has significant advantages in improving surgical ac-curacy,reducing intraoperative blood loss,shortening operative time,and decreasing the number of fluoroscopic exposures.

Objective:To search, evaluate, and summarize the best evidence for postpartum contraceptive health guidance, providing evidence-based support for clinical healthcare providers in implementing standardized contraceptive counseling and management.Methods:A systematic search was conducted across guideline repositories, professional association websites, and databases for literature related to postpartum contraception guidance, including guidelines, best practices, expert consensus, and systematic reviews, with a search timeframe from database inception to December 2023. Four researchers independently evaluated the quality of the included studies, extracted relevant data, and synthesized evidence from eligible literature.Results:According to the inclusion and exclusion criteria, 18 documents were included, comprising 5 guidelines, 2 clinical decision-making documents, 1 best practice document, 4 expert consensus statements, and 6 meta-analyses or systematic reviews. Totally 46 pieces of best evidence were summarized from 9 aspects, including health educators, health education recipients, assessment, planning, mode and content of health education, available contraceptive methods, evaluation index of health education, and considerations.Conclusion:This study systematically synthesizes the best available evidence on postpartum contraceptive health guidance. It emphasizes strengthening the competencies of clinical practitioners, supported by structured assessments and standardized guidance, to improve the feasibility and accessibility of contraceptive services. It further highlights the importance of ensuring the long-term sustainability of contraceptive plans and integrating digital tools to enhance the precision and coverage of guidance, ultimately reducing unintended and short-interval pregnancies and safeguarding women's reproductive health.

Objective:To systematically evaluate studies validating the performance of the Global Leadership Initiative on Malnutrition (GLIM) in diagnosing malnutrition.Methods:Seven Chinese and English databases including Embase, Web of Science (WOS), PubMed, CINAHL, Cochrane Library, SinoMed, CNKI, Wanfang Data, and VIP Database were searched for articles on the validation of GLIM criteria published between September 2018 and September 2024. Two researchers independently performed literature screening and data extraction. The concurrent and predictive validity of the criteria was analyzed.Results:A total of 136 papers were included for analysis. The GLIM criteria for diagnosing malnutrition had a sensitivity of 77%, a specificity of 87%, and an area under the curve (AUC) of 0.90. Malnutrition diagnosed by the GLIM criteria predicted prolonged hospital and intensive care unit (ICU) stays, increased readmission and complication rates (both overall and infectious), reduced survivals (median, overall, and disease-free), and increased in-hospital and follow-up mortalities. Both moderate and severe malnutrition predicted decreased overall survival. However, only three studies analyzed the impact of nutritional therapy on the clinical outcomes of malnourished patients.Conclusions:The GLIM criteria accurately differentiate malnutrition and are a valid predictive tool of clinical outcomes. However, the validity criteria in these validation studies were questionable, along with high methodological heterogeneity. Furthermore, there is a lack of studies validating the role of nutritional therapy in improving the clinical outcomes of malnourished patients.

Objective:To translate the Short Self-Regulation Questionnaire (SSRQ) into Chinese, and test its reliability and validity in breast cancer patients.Methods:Using the Brislin translation model, cross-cultural adaptation was conducted by combining expert consultation and a pre-survey on SSRQ. From August to December 2023, 324 breast cancer patients from Department of Breast Surgery of Peking University First Hospital were selected by convenience sampling to test the reliability and validity of SSRQ.Results:A total of 324 questionnaires were distributed and 307 valid questionnaires were recovered, with an effective recovery rate of 94.75% (307/324). The final questionnaire consisted of 30 items. The content validity index at the item level ranged from 0.80 to 1.00, and the content validity index at the scale level was 0.97. The predictive validity result showed a good model fit. The Cronbach's α coefficient for the questionnaire was 0.90, the folded reliability coefficient was 0.85, and the retest reliability coefficient was 0.79.Conclusions:SSRQ has good reliability and validity in breast cancer patients and has value for clinical promotion.

Objective:To conduct a systematic review of risk prediction models for enteral feeding intolerance in ICU patients.Methods:Relevant literature was searched in China National Knowledge Infrastructure, Wanfang Data, China Biology Medicine disc, VIP, PubMed, Web of Science, Cochrane Library, Embase, CINAHL, and Scopus, with search limits from the establishment of the databases up to July 24, 2024. Two researchers independently screened the literature and extracted data, using Prediction model Risk Of Bias ASsessment Tool to evaluate the quality of the included studies.Results:A total of 12 studies were included, which included 20 prediction models. The area under the receiver operating characteristic curve or C-index for these models ranged from 0.70 to 0.94. The overall bias risk of the 12 studies was high, with three studies having good applicability. The bias risk primarily stemmed from issues such as measurement of prediction factors, variable handling, sample size, outcome definition, and model performance evaluation.Conclusions:Existing risk prediction models for enteral feeding intolerance in ICU patients exhibit a high risk of bias. Further validation, optimization, or development of new models is required in the future.
