Objective To explore the effectiveness of the generative large language model MedGo in nursing decision-making for elderly patients with multimorbidity. Methods A quasi-randomized controlled trial study was conducted involving 6 junior nurses, 6 senior nurses and the MedGo model from January 1, 2025 to March 31, 2025 at the Emergency Internal Medicine Ward of Shanghai East Hospital Affiliated to Tongji University. Clinical data of 120 elderly patients with multimorbidity were analyzed to compare the performance of the three groups in four tasks (nursing diagnosis assessment, nursing intervention formulation, complication identification, and complication prevention) from three evaluation dimensions: decision-making time consumption, decision accuracy, and decision-making quality. Results In terms of decision-making time, the senior nurse group completed all four tasks faster than the junior nurse group (P＜0.01), and the MedGo group completed all four tasks faster than the junior nurse group (P＜0.001) and the senior nurse group (P＜0.001). In terms of decision-making accuracy, senior nurse group scored higher than junior nurse group in all four tasks (P＜0.001), while the MedGo group outperformed the senior nurse group only in complication identification (P＜0.001). In terms of decision-making quality, the MedGo group scored higher than junior nurse group (P＜0.001) and senior nurse group (P＜0.001) in all four tasks. Conclusions The MedGo model demonstrates advantages of high efficiency, accuracy, and quality in nursing decision-making for elderly patients with multimorbidity; senior nurses outperform junior nurses in decision-making, providing diverse references for clinical nursing decision-making.

OBJECTIVE: To explore the incidence, clinical features, genetic variant characteristics and prognosis of Glutaric acidemia type I (GA1) among neonates from Henan Province. METHODS: A total of 814 625 neonates undergoing screening for inherited metabolic diseases by tandem mass spectrometry (MS/MS) at the Third Affiliated Hospital of Zhengzhou University from January 2016 to December 2022 were selected as the study subjects. A retrospective method was adopted to collect the clinical data of the patients. Whole exome sequencing was carried out to detect GCDH gene variants in individuals with positive results by GA1 newborn screening, and Sanger sequencing was used to verify the candidate variants. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the pathogenicity of candidate variants was rated. This study was approved by the Medical Ethics Committee of the Hospital (Ethics Number: 2019 Medical Ethics Review No. 67). RESULTS: Eight cases of GA1 were diagnosed among the 814 625 neonates. Blood glutaryl carnitine (C5DC) and urine glutaric acid (GA) levels of the 8 children were higher than the normal reference values. In total 12 variants were detected, all of which were missense variants. c.1064G>A (p.Arg355His) was the most common one, accounting for 21.4% (3/14). Three GCDH gene variants, including 1297G>C (p.Ala433Pro), c.467G>A (p.Gly156Asp) and c.1125T>G (p.Cys375Trp), were previously unreported. REVEL software analysis predicted that all of the three variants were harmful. 3D protein structure modeling indicated that the three variants may cause amino acid residue alterations, and c.1297G>C (p.Ala433Pro) and c.1125T>G (p.Cys375Trp) may result in increase in hydrogen bonds and affect the function of GCDH protein. By December 2023, one of the eight children had deceased, and another child had severe clinical symptoms with poor prognosis. Six children had a good prognosis, of which two had mild motor development delay and four had normal development without clinical symptoms. CONCLUSION The incidence of GA1 in newborns screened by MS/MS in Henan Province is 1/101 828, and the carrier rate of pathogenic GCDH variants is 1/160. The c.1064G>A (p.Arg355His) may be the hotspot variant of the GCDH gene among children with GA1 in Henan. Discovery of the three novel variants has enriched the mutational spectrum of the GCDH gene and provide a basis for the early diagnosis, treatment, prognosis and genetic counseling of this disease.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To evaluate the feasibility of the novel programmed death-ligand 1 (PD-L1)-targeted PET/CT molecular probe for evaluating PD-L1 expression and tumor heterogeneity in patients with non-small cell lung cancer (NSCLC).Methods:From October 2023 to October 2024, 30 patients (21 males, 9 females; age 69(58, 75) years) with newly diagnosed NSCLC at the First Affiliated Hospital of Xiamen University were prospectively enrolled. All patients underwent PET/CT imaging 1 h after intravenous administration of 68Ga-1, 4, 7-triazacyclononane-1, 4, 7-triacetic acid (NOTA)-DK224, and SUV max was calculated. Immunohistochemical staining on biopsy samples of patients were performed and the PD-L1 tumor proportion score (TPS) was calculated. The differences of SUV max between two groups were compared by using Mann-Whitney U test. Results:Of 30 patients, 31 biopsy specimens were obtained including 24 primary lesion biopsies, 1 lymph node lesion biopsy, and 6 metastatic lesion biopsies, with 16 TPS<1%, 9 1%≤TPS<50% and 6 TPS≥50%. PD-L1-positive tumors showed relatively high uptake of 68Ga-NOTA-DK224. The SUV max of TPS≥1% group was significantly higher than that of TPS<1% group (6.9(5.1, 7.7) vs 3.8(3.1, 4.2); Z=-4.47, P<0.001), and SUV max of TPS≥50% group was significantly higher than that of TPS<50% group (8.6(7.3, 12.4) vs 4.2(3.7, 5.3); Z=-3.65, P<0.001). Of 30 patients, 24 had multiple metastatic lesions with 212 lesions in total. The median fold difference was 2.3 (range: 1.4-6.0), and the median CV was 28.3% (range: 11.7%-61.6%). Conclusion:68Ga-NOTA-DK224 PET/CT is able to accurately and comprehensively reflect PD-L1 expression and tumor heterogeneity in primary and metastatic NSCLC.

Objective:To investigate the association between abdominal fat-related indicators derived from quantitative computed tomography (QCT) and coronary artery calcification (CAC) in middle-aged and elderly individuals, as well as the diagnostic value of these indicators.Methods:This cross-sectional study enrolled middle-aged and elderly participants who underwent health check-ups at Kaifeng Central Hospital between January and December 2024. Participants were divided into a CAC group and a non-CAC group based on the presence or absence of CAC. The CAC group was then stratified into mild, moderate, and severe subgroups according to CAC severity. General clinical data were collected for all participants. All subjects underwent one-stop QCT scanning of the chest and abdomen. An automated abdominal fat analysis system was used to identify fat distribution regions. If accurate identification was not possible, a semi-automated segmentation algorithm combined with manual correction was applied instead. Two physicians performed the measurements independently, and inter-observer consistency was assessed. The average values were calculated to obtain visceral fat area (VFA) and subcutaneous fat area (SFA). The ratio of visceral fat area to subcutaneous fat area (VFA/SFA) was also computed. Multivariate logistic regression analysis was performed to identify the factors associated with CAC in middle-aged and elderly individuals. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic efficacy of these indicators for CAC. DeLong′s test was used to compare the differences in the area under the curve ( AUC). Results:A total of 252 middle-aged and elderly individuals were included, with a median age of 61 (interquartile rang: 59, 69) years. Of these individuals, 188(74.6%) were males. Among them, 172 were classified into the CAC group and 80 into the non-CAC group. Multivariate logistic regression analysis revealed that VFA, VFA/SFA ratio, age, low-density lipoprotein cholesterol(LDL-C), and hypertension were independently associated with CAC in middle-aged and elderly individuals (all P<0.05). The mild, moderate, and severe CAC subgroups comprised 78, 51, and 43 participants, respectively. Analysis of variance (ANOVA) demonstrated that VFA and VFA/SFA increased with CAC severity, and there were statistically significant differences between the subgroups (all P<0.05). ROC curve analysis showed that the AUCs of VFA and VFA/SFA for diagnosing CAC were 0.841 and 0.810, respectively, with no significant difference between them ( P>0.05). The optimal cutoff values were 177.45 cm2 for VFA (sensitivity: 83.1%, specificity: 72.5%) and 1.592 for VFA/SFA (sensitivity: 65.7%, specificity: 83.7%). For the diagnosis of moderate-to-severe CAC, the AUCs of VFA and VFA/SFA were 0.765 and 0.761, respectively ( P>0.05 for comparison), with cutoff values of 231.75 cm2 (sensitivity: 61.7%, specificity: 83.3%) and 1.962 (sensitivity: 64.9%, specificity: 80.8%). Conclusion:Abdominal VFA and VFA/SFA derived from QCT are independently associated with the presence of CAC in middle-aged and elderly individuals, demonstrating good diagnostic performance for both overall CAC and moderate-to-severe CAC.
