Transfusion and Anemia Expertise Initiative-Control/Avoidance of Bleeding developed a strategy for platelet and plasma infusion management in critically ill children based on systematic reviews and consensus meetings of international multidisciplinary experts. One good practice statement and six expert consensus statements were proposed for plasma and platelet transfusions in critically ill children following severe trauma, traumatic brain injury, and/or intracranial hemorrhage. This article introduces the specific methods and basis for the formation of recommendations in this part of the guide.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Objective:To explore the application effectiveness of the "summarize-narrow-analyze-probe-plan-select" (SNAPPS) teaching method in early clinical training of pediatrics, compare this method with traditional teaching approach, and provide new insights for curriculum instruction.Methods:A prospective randomized controlled trial was conducted with 100 students enrolled in the Introduction to Pediatrics course at Chongqing Medical University. Participants were divided into an experimental group (SNAPPS method) and a control group (traditional lecture-based method). Both groups studied five core chapters and were assessed using mini-clinical evaluation exercise with standardized patient models. Teaching experience and satisfaction were evaluated through questionnaires and interviews, followed by quantitative and qualitative analyses. Statistical analysis was performed using GraphPad Prism 8. Continuous variables were expressed as mean ± standard deviation and independent samples t-test was used for between-group comparisons. Ordinal data were expressed as median (interquartile range) and Mann-Whitney U test was used for between-group comparisons. Results:The experimental group outperformed the control group in medical history collection [(9.20±0.70) vs. (8.50±0.90), t=4.34, P<0.001], clinical judgment [(9.30±0.60) vs. (8.60±0.80), t=3.89, P=0.003], and overall performance [(9.00±0.90) vs. (8.30±1.00), t=3.51, P=0.002]. However, there were no significant differences between the two groups in physical examination, communication skills, professional behavior, organization and efficiency, or health education and counseling. Self-assessment results indicated significant improvements in the experimental group in case summarization, clinical reasoning, diagnostic accuracy, treatment planning ability, and self-directed learning ability ( P<0.05). Regarding teaching satisfaction, evaluations from both students and instructors were higher in the experimental group than in the control group ( P<0.05), indicating a preference for the SNAPPS teaching model. Conclusions:The SNAPPS teaching method demonstrates significant advantages in cultivating clinical thinking, self-directed learning, and treatment planning abilities, effectively enhancing teaching satisfaction and providing an effective teaching model for early clinical training of medical students.

Objective To explore the value of combined detection of cerebrospinal fluid lactate (LA), interleukin-27 (IL-27) and interferon-γ (IFN-γ) in diagnosing bacterial meningitis after neurosurgical operation in Intensive Care Unit (ICU). Methods A total of 54 patients with bacterial meningitis after neurosurgical operation in ICU were collected as disease group, and 62 patients without bacterial meningitis after operation were collected as control group. Fully automated biochemical analyzer and enzyme-linked immunosorbent assay (ELISA) were used to detect the expression levels of LA, IL-27 and IFN-γ in cerebrospinal fluid; the Logistic regression model was used to analyze the related factors affecting bacterial meningitis after operation; the receiver operating characteristic (ROC) curve was used to analyze the diagnostic values of LA, IL-27 and IFN-γ in cerebrospinal fluid for bacterial meningitis after operation. Results The glucose level in the disease group was significantly lower than that in the control group, while the white blood cell count and protein level were significantly higher than those in the control group (P < 0.01). The expression levels of LA and IL-27 in the cerebrospinal fluid in the disease group were significantly higher than those in the control group, while IFN-γ level in the cerebrospinal fluid was significantly lower than that in the control group (P < 0.01). Logistic regression analysis showed that LA, IL-27 and IFN-γ in the cerebrospinal fluid were the influencing factors of bacterial meningitis after neurosurgical operation in ICU (P < 0.05). The area under the curve (AUC) of LA combined with IL-27 and IFN-γ in cerebrospinal fluid in the diagnosis of bacterial meningitis after neurosurgical operation in ICU was 0.955, which was better than that of single diagnosis based on LA (AUC=0.806, Z=4.029, P < 0.001), IL-27 (AUC=0.858, Z=2.513, P=0.012) and IFN-γ (AUC=0.815, Z=3.680, P < 0.001) in cerebrospinal fluid, and the sensitivity and specificity of the combined diagnosis were 87.04% and 93.55% respectively. Conclusion The expression levels of LA and IL-27 in the cerebrospinal fluid of patients with bacterial meningitis after neurosurgical operation in ICU increase significantly, while the expression level of IFN-γ in the cerebrospinal fluid is significantly lower. The combined detection of three indicators has higher diagnostic value for postoperative bacterial meningitis compared with single detection.

Objective To investigate expression levels and clinical significance of annexin A2 and S100 calcium binding protein A10 (S100A10) in cerebrospinal fluid of patients with secondary intracranial infection after craniocerebral surgery. Methods A total of 120 patients with secondary intracranial infection after craniocerebral surgery were selected as test group, while 120 patients with no infection after craniocerebral surgery in the same period were selected as control group. The levels of Annexin A2 and S100A10 in cerebrospinal fluid were detected by enzyme-linked immunosorbent assay(ELISA). Pearson correlation analysis was applied to analyze the correlations of Annexin A2 and S100A10 with clinical indicators. Logistic regression analysis was applied to analyze the influencing factors of secondary intracranial infection after craniocerebral surgery. Receiver operator characteristic (ROC) curve was applied to analyze the predictive value of Annexin A2 and S100A10 levels for the occurrence of secondary intracranial infection after craniocerebral surgery. Results The proportions of diabetes and cerebrospinal fluid leakages, blood l actate dehydrogenase (LDH), cerebrospinal fluid Annexin A2 and S100A10 levels in the test group were higher than those in the control group (P < 0.05). Annexin A2 in cerebrospinal fluid of patients with intracranial infection was positively correlated with S100A10, LDH, and S100A10 level was positively correlated with LDH (P < 0.05). Multivariate Logistic regression analysis showed that diabetes, cerebrospinal fluid leakage, blood LDH, Annexin A2 and S100A10 in cerebrospinal fluid were independent influencing factors for secondary intracranial infection after craniocerebral surgery (P < 0.05). ROC results showed that the AUCs of Annexin A2 level or S100A10 level alone in cerebrospinal fluid and their combined prediction for secondary intracranial infection after craniocerebral surgery was 0.788, 0.768 and 0.865 respectively, the AUC of combined prediction was larger than that of the single prediction (P < 0.05). Conclusion The expression levels of Annexin A2 and S100A10 are increased in cerebrospinal fluid of patients with secondary intracranial infection after craniocerebral surgery, which are independent influencing factors for secondary intracranial infection after craniocerebral surgery. Their combination has higher predictive value for secondary intracranial infection after craniocerebral surgery.

Objective To observe the value of 18F-FDG PET/CT semi-quantitative parameters for predicting spread through air spaces(STAS)of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.Methods Data of 85 patients with clinical stage Ⅰa—Ⅲ a lung adenocarcinoma who underwent preoperative 18F-FDG PET/CT were retrospectively analyzed.The patients were divided into positive group(n=23)or negative group(n=62)according to whether pathology showed STAS or not.Clinical and PET/CT data were compared between groups,and logistic analysis was performed to explore the efficacy of each parameter for predicting STAS.Results Significant differences of gender,carcinoma embryonic antigen,clinical stage,pathological grade,micropapillary growth and proportion were found between groups(all P＜0.05).The maximum,the mean,the peak standard uptake value(SUVmax,SUVmean,SUVpeak),as well as the maximum,the mean and the peak standard uptake value normalized by lean body mass(SULmax,SULmean,SULpeak),also the total lesion glycolysis(TLG)in positive group were all significantly higher than those in negative group(all P＜0.05).Patients'gender,proportion of micropapillary growth,SUVmax and SULmax were all independent risk factors of STAS of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.The area under the curve(AUC)of the above parameters for predicting STAS was 0.666,0.912,0.839 and 0.842,respectively,and of the combination was 0.957.Conclusion 18 F-FDG PET/CT semi-quantitative parameters SUVmax and SULmax were helpful for predicting STAS of clinical stage Ⅰa—Ⅲ a lung adenocarcinoma,and further combination of gender and proportion of micropapillary growth could improve diagnostic efficacy.

Objective To explore the impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. Methods The Medline, EMbase, CENTRAL, CNKI, Wanfang Data, VIP and China Biology Medicine from inception to May 2023 were searched by computer for studies about impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. The data were extracted from all the relevant literatures, and the quality of the data was assessed using the Newcastle-Ottawa Scale (NOS). All statistical analyses were conducted by the Stata 11.0 software. Results A total of 10 studies (NOS score ranging from 5 to 9 points) involving 643 patients were enrolled. The pooled results demonstrated that the pooled mortality of heart transplant recipients from SARS-CoV-2-positive donors was 4% (95%CI 2% to 5%). And the incidence of composite outcome, regarding graft failure, rejection and death as poor prognosis, was 7% (95%CI 5% to 9%). Besides, compared with recipients from SARS-CoV-2-negative donors, the pooled odds ratio (OR) value of death of SARS-CoV-2-positive donors was 0.68 (95%CI 0.38 to 1.22, Z=1.28, P=0.200). The pooled OR value of rejection rate was 0.41 (95%CI 0.27 to 0.64, Z=3.97, P<0.005). For the composite outcome, the pooled OR value was 0.50 (95%CI 0.37 to 0.69, Z=4.30, P<0.005). In addition, there was no statistical difference in the length of hospital stay between heart transplant recipients from SARS-CoV-2-positive donors and negative donors (SMD=–0.03, 95%CI –0.22 to 0.15, Z=0.36, P=0.720). Conclusion The application of heart from SARS-CoV-2-positive donor for transplantation is safe and feasible. However, further prospective studies with longer follow-up are still needed to verify its impact on long-term outcomes.
