Objective: To explore the correlation between allogeneic red blood cell (RBC) transfusion and healthcare-associated infections (HAIs) in patients undergoing coronary artery bypass grafting (CABG) during the perioperative period. Methods: A single-center retrospective cohort of 1,170 patients undergoing isolated CABG was analyzed. Multivariable logistic regression and restricted cubic splines (RCS) were employed to explore the nonlinear association between perioperative RBC transfusion (from intraoperative period to 72 hours postoperatively) and HAIs. Results: Among the 1,170 CABG patients, 109 patients (9.2%) received RBC transfusion during the operation or within 3 days after the operation. The risk of HAIs in those who received ≥4 units of RBCs during and within 3 days after the operation was 6.89 times higher than that in the non-transfusion group (95% CI: 3.65-17.20). Furthermore, there was a nonlinear threshold effect between the blood transfusion volume and postoperative HAIs (inflection point: 7.8 units). When the transfusion volume was ≤7.8 units, the risk of HAIs increased by 61% for each additional unit transfused (OR=1.61, 95% CI: 1.21-2.15). Beyond this threshold, no statistically significant association was observed (P=0.289). Conclusion: Perioperative RBC transfusion in CABG patients is associated with an increased incidence of HAIs. The perioperative blood transfusion volume has a curvilinear relationship with the risk of postoperative HAIs. When the blood transfusion volume is ≤7.8 units, the blood transfusion volume has a dose-dependent relationship with postoperative infection, with higher blood transfusion volumes correlating with greater postoperative infection risk. When the blood transfusion volume is >7.8 units, the relationship between the two is not statistically significant. The preventive effect of reducing RBC transfusion on HAIs requires further validation in the future.

ObjectiveTo investigate the microbiological characteristics of bile in patients with common bile duct stones alone or comorbid with juxtapapillary duodenal diverticula （JPDD）. MethodsA prospective study was conducted among 30 patients with common bile duct stones who were admitted to Department of Gastroenterology， Hebei General Hospital， from January to May 2024， and according to the presence or absence of JPDD， they were divided into JPDD group and simple common bile duct stones group （CBD group）， with 15 patients in each group. Bile samples were collected during endoscopic retrograde cholangiopancreatography， and 16S rRNA microbial sequencing was performed to compare the differences in microbial composition， diversity， and metabolic pathways between the two groups. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. Pearson correlation analysis or Spearman correlation analysis was used to analyze the correlation between clinical indicators and microbial species abundance. ResultsClinical data showed that compared with the CBD group， the JPDD group had significantly greater maximum diameter of stones （10.87±3.42 mm vs 6.80±2.08 mm， t=3.94， P0.01） and common bile duct diameter （14.73±3.95 mm vs 9.67±2.64 mm， t=4.13， P0.01）. The microbiological analysis of the bile showed that Proteobacteria， Bacteroidetes， Firmicutes， and Actinobacteria were the most common phyla in both groups， and Proteobacteria was the dominate phylum in the JPDD group. At the genus and species levels， the JPDD group had higher relative abundances of Escherichia-Shigella， Enterococcus， and Escherichia coli. Alpha diversity was similar between the two groups， and there was a significant difference in beta diversity between the two groups （Adonis test， P0.05）. The LEfSe analysis identified 25 differentially expressed species （LDA2） between the two groups， and the JPDD group had enrichment of 7 flora such as Enterobacter， Enterococcaceae， and Klebsiella， while the CBD group had significant enrichment of 18 flora such as Peptococcaceae， Roseburia， and Alistipes （P0.05）. The correlation analysis showed that Enterococcaceae and Enterococcus significantly enriched in the JPDD group were positively correlated with the diameter of the common bile duct and the maximum diameter of stones （P0.01）， whereas Peptococcaceae， Acinetobacter， and Alistipes with reductions in expression were negatively correlated with the diameter of the common bile duct and the maximum diameter of stones （P0.05）. The enrichment analysis of biliary microbial metabolic pathways showed that there were significant differences between the two groups in 10 metabolic pathways such as cell growth and death， transportation and decomposition， nervous system， biosynthesis of valine， leucine， and isoleucine， and histidine metabolism （P0.05）. ConclusionThe presence of JPDD may lead to alterations in bile microbiota， such as an increase in Enterococcus and a reduction in Roseburia， and specific flora and metabolism can promote the formation of common bile duct stones.

OBJECTIVE: To explore the clinical characteristics and prognostic factors of patients with extranasal NK/T-cell lymphoma (NKTCL). METHODS: The clinical data of 138 patients with NKTCL diagnosed in 10 medical centers of Huaihai Lymphoma Working Group from June 2015 to April 2021 were collected and analyzed retrospectively. The differences in clinicopathological characteristics of patients with different involvement and efficacy of pegaspargase regimen were compared, as well as perform survival analysis. RESULTS: A total of 138 extranasal NKTCL patients were included, with a median age of 46 years, and the ratio of males to females was approximately 2∶1. There were 39 patients with gastrointestinal involvement, 32 patients with oropharyngeal involvement, 17 patients with skin involvement, 11 patients with lymph node involvement, 11 patients with orbital involvement, and 28 patients with other parts involvement. Patients with skin involvement had a higher proportion of advanced disease and a lower proportion of CD56 positive rate compared to those with oropharyngeal involvement. Among the patients with gastrointestinal involvement, the survival rate of patients who received pegaspargase regimen was significantly higher than those who were treated without pegaspargase (P < 0.01). Multivariate analysis showed that serum creatinine was an independent prognostic factor for patients with skin involvement ( HR =1.027, 95%CI : 1.001-1.054, P =0.040), ECOG PS and EBV DNA were independent prognostic factors for patients with gastrointestinal involvement ( HR =2.635, 95%CI : 1.096-6.338, P =0.030; HR =4.772, 95% CI : 1.092-20.854, P =0.038), and ECOG PS and CA stage were independent prognostic factors for patients with oropharyngeal involvement ( HR =13.875, 95%CI : 2.517-76.496, P =0.002; HR =20.261, 95%CI : 2.466-166.470, P =0.005). CONCLUSION The clinicopathological characteristics of extranasal NKTCL patients with different sites of involvement are vary, and effective individualized treatment need to be further explored.

Objective:To investigate the important clinical features and prognosis of febrile infection-related epilepsy syndrome(FIRES).Methods:A retrospective analysis was performed for the data of 15 children with FIRES who were hospitalized and treated in Peking University First Hospital from March 2022 to June 2024,including clinical features,treatment regimens,and prognosis,and follow-up was performed by telephone.Results:The median duration of status epilepticus was 15 days for all children.Of all 15 children,14(93.3%)were comorbid with disturbance of consciousness,8(53.3%)were comorbid with respiratory failure and underwent endotra-cheal incubation,and 13(86.7%)had been admitted to the intensive care unit.In the acute stage,7 children underwent the examination of various inflammatory factors in blood and cerebrospinal fluid,including interleukin(IL)-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,and tumor necrosis factor-α,and all 7 children had significant increases in the levels of inflammatory factors in cerebrospinal fluid,which were significantly higher than the levels of inflammatory factors in serum.Of all 15 children,12(80%)had diffuse slow wave changes on electroencephalography,and migrating focal seizures were detected in 7 children(46.7%).Cranial magnetic resonance im-aging(MRI)manifestations in the acute stage included temporal and insular cortical edema(60%),abnormal white matter signal(33.3%),and claustrum sign(13.3%),and MRI features in the chronic stage included the deepening of cerebral sulci(75%)and ventricular dilatation(33.3%).The treatment in the acute stage in-cluded intravenous drip of gamma-globulin and high-dose methyl-prednisolone in 15 children(effective in 2 children),ketogenic diet in 4 children(effective in 1 child),tocilizumab in 5 children(effective in 3 children),and anakinra in 2 children(effective in 1 child).As of the last follow-up,the median duration of disease was 14.0 months(4-65 months)for all patients,and only 2 children achieved complete seizure control,while the remaining 13 children had refractory epilepsy.Cognitive impairment was observed in 93.3%of the children.Conclusion:FIRES often has acute and severe conditions,and first-line immunotherapies often have a poor therapeutic ef-fect.Tocilizumab and anakinra may be effective in some patients with seizures in the acute stage.

Objective:To investigate the cranial magnetic resonance imaging(MRI)characteristics of children with febrile infection-related epilepsy syndrome(FIRES).Methods:A retrospective analysis was performed for the imaging characteristics of children with FIRES who were admitted to Department of Pediatrics,Peking University First Hospital,from November 2020 to August 2024,includ-ing the characteristic manifestation of claustrum sign on cranial MRI.Results:A total of 86 children with a confirmed diagnosis of FIRES were included,among whom there were 65 boys(75.6%)and 21 girls(24.4%),with a median age of onset of 6.35(4.4,8.32)years.Among these children,14(16.3%)had normal cranial MRI findings in the acute stage,with T2 FLAIR changes as the most common abnormal manifestation(39.5%),and 30 children(34.9%)experienced brain atrophy,with a median time of 44(34,72)days for the onset of brain atrophy for the first time.There were 22 children(25.6%)with positive bilateral claustrum sign on cranial MRI,which manifested as symmetrical T2 FLAIR hyperintensity with limited diffusion in the bilateral claustrum,and the median time to the first appearance of claustrum sign was 11(7,15)days,while the median time to negative conversion of claustrum sign was 33(24,50)days.The claustrum sign disappeared after the relief of status epilepticus in the acute stage in most children.Among the children in this study,71 entered the chronic stage during follow-up,3 had normal cranial MRI results during the course of the disease,and 34 had brain atrophy for the first time in the chronic stage,with a median time of 186(115,429)days to the first appearance of brain atrophy on cranial MRI,while of all 86 children,64(80.0%)experienced brain atrophy on cranial MRI in the acute stage and the chronic stage.Conclusion:Children with FIRES have diverse cranial MRI characteristics.There might be normal MRI manifestations at the beginning of the disease,and positive bilateral claustrum sign might be the specific manifestation in the acute stage.Changes in the claustrum disappear after the relief of status epilepticus in most cases,and most patients may progress to brain atrophy in the chronic stage.

Objective:To investigate the efficacy and safety of ketogenic diet,anakinra,and tocilizumab in the treatment of febrile infection-related epilepsy syndrome(FIRES)through a meta-analysis.Methods:With FIRES,ketogenic diet,anakinra,and tocili-zumab as search terms,the databases of PubMed,Embase,Web of Science,the Cochrane Library,Clinicalttrials.gov,CNKI,Wanfang Data,and VIP were searched for related articles published up to December 13,2024.Two reviewers independently screened the ar-ticles according to the inclusion and exclusion criteria and assessed the risk of bias of the studies included.Review Manager was used to perform the meta-analysis.Results:Among the 549 studies,45 case reports and case series met the inclusion criteria,and there were 45 retrospective studies in total,among which 25,8,and 17 were included in the ketogenic diet group,the tocilizumab group,and the anakinra group,respectively,with 66 patients in the ketogenic diet group,8 in the the tocilizumab group,and 54 in the anakinra group.There were 3 case reports,in which all 3 patients were treated with tocilizumab and anakinra.The meta-analysis showed that in the treatment of FIRES in the acute stage,ketogenic diet,anakinra,and tocilizumab showed a response raet of 68%(95%CI=51%-85%,I 2=71%,P<0.01),57%(95%CI=35%-80%,I 2=71%,P<0.01),and 100%(95%CI=79%-100%,I 2=0%,P=1.00),respec-tively,with no statistical differences between studies.The survival rate was 96%(95%CI=89%-100%,I 2=0%,P=1.00)in the keto-genic diet group,96%(95%CI=89%-100%,I 2=0%,P=1.00)in the FIRES,and ketogenic diet and anakinra treatment have a relatively high incidence rate of adverse reactions.Hypoglycemia and infec-tion are adverse reactions commonly observed during treatment.

Objective:To investigate the predictive value of controlling nutritional status (CONUT) score in the prognosis of patients with advanced diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was performed. The clinical data of 654 patients newly diagnosed with advanced DLBCL diagnosed in 7 medical centers in Huaihai Lymphoma Working Group from October 2009 to January 2022 were retrospectively collected. All the patients received rituximab-based immune chemotherapy regimens. The patients were randomly assigned to the training set (458 cases) and the validation set (196 cases) in a 7:3 ratio. The clinicopathological data of patients were collected, and the CONUT score was calculated based on albumin, lymphocyte count, and total cholesterol. The optimal critical value of CONUT scote was determined by using MaxStat method. Kaplan-Meier method was used to draw survival curves; Cox proportional hazards model was used to make univariate analysis and multivariate analysis on the factors influencing overall survival (OS). The efficacy of CONUT score in combination with the International prognostic index (IPI) and an enhanced IPI (NCCN-IPI) in predicting OS was evaluated by using receiver operating characteristic (ROC) curves.Results:The median follow-up time of 654 patients was 38.1 months (95% CI: 35.3 months- 40.9 months), and the 5-year OS rate was 49.2%. According to the MaxStat method, the optimal critical value for CONUT score was determined to be 6 points. All the patients were classified into the normal nutritional status group (CONUT score ≤ 6 points, 489 cases) and the poor nutritional status group (CONUT score > 6 points, 165 cases). The results of the multivariate analysis showed that CONUT score > 6 points, male, lactate dehydrogenase >240 U/L, high white blood cell count, low hemoglobin level and age > 60 years were independent risk factors for OS of patients with advanced DLBCL (all P < 0.05). Patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group in the overall cohort of advanced DLBCL. Subgroup analysis revealed that among patients with Eastern Cooperative Oncology Group-performance status (ECOG PS) score < 2 points, IPI low-intermediate risk, IPI intermediate-high risk, NCCN-IPI low-intermediate risk, and NCCN-IPI intermediate-high risk, the patients in the poor nutritional status group (CONUT score > 6 points) had worse OS compared with that in the normal nutritional status group (CONUT score ≤ 6 points) (all P < 0.05). Conclusions:CONUT score has a certain value in the assessment of the prognosis of patients with advanced DLBCL, and its predictive efficacy is further improved when combined with IPI and NCCN-IPI.

Background::Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China.Methods::Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed.Results::A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43–0.68; P <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04–13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65–3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38–1.53; P <0.001). Conclusions::In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration::ClinicalTrials.gov, NCT02309398.

Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Purpose: This study explored the association of the elasticity modulus and shear wave velocity (SWV) of the tibialis anterior muscle, as measured by two-dimensional shear wave elastography (2D-SWE), with the intracompartmental pressure (ICP) determined using the Whitesides method in a New Zealand rabbit model of acute compartment syndrome (ACS). Additionally, it evaluated the viability of 2D-SWE as a noninvasive, quantitative tool for the early detection of ACS. Methods: An ACS model was established through direct external compression by applying pressure bandaging to the lower legs of 15 New Zealand rabbits using neonatal blood pressure cuffs. Another five animals represented a non-modeled control group. To measure the elasticity modulus and SWV of the tibialis anterior muscles, 2D-SWE was employed. Blood oxygen saturation, serum creatine kinase (CK), and myoglobin levels were monitored. Subsequently, the anterior tibial compartment was dissected, and the tibialis anterior was removed for hematoxylin and eosin staining to assess muscle injury. Results: The elasticity modulus and SWV of the tibialis anterior muscle increased with compression duration, as did serum CK and myoglobin levels. ICP was strongly positively correlated with these parameters, particularly mean velocity (r=0.942, P<0.001) and CK (r=0.942, P<0.001). Blood oxygen saturation was negatively correlated with ICP (r=-0.887, P<0.001). Histological analysis indicated progressive muscle cell swelling over time, with damage transitioning from reversible to irreversible and culminating in necrosis. Conclusion In a rabbit ACS model, ICP was strongly positively correlated with muscle elasticity modulus/SWV. Consequently, 2D-SWE may represent a novel tool for assessing early-phase ACS.
