Objective To investigate the causal relationships between anxiety disorders and coronary heart disease(CHD),atrial fibrillation(AF),heart failure(HF),stroke and myocardial infarction(MI)risks by using the bidirectional two-sample Mendelian randomization study method.Methods The data were collected from the genome-wide association study(GWAS)conducted within the population-based Danish Lundbeck Foundation Initiative for Integrative Psychiatric Research(iPSYCH)study,as well as from five other databases related to cardiovascular diseases.The inverse variance weighting(IVW)method was used to produce the main results,and four methods,including MR-Egger regression,weighted median method,weighted model,and simple model,supplemented the results.Sensitivity analyses such as heterogeneity,horizontal pleiotropy,and leave-one-out analysis were also performed.Results The IVW and MR-Egger regression showed that anxiety disorders would increase the risk of coronary heart disease(IVW:OR=1.0001,95％CI=1.0001-1.0025,P=0.040;MR-Egger:OR=1.0030,95％CI=1.0009-1.0058,P=0.013).There was no evidence of a causal effect of cardiovascular diseases on anxiety disorders risks.There was no horizontal pleiotropy and heterogeneity in the instrumental variables of this study.The result of sensitivity analysis was robust.Conclusion The study supports the causal effect of anxiety disorders on CHD risk,but no association is found with an increased risk of other cardiovascular diseases,such as AF,HF,stroke,and MI.No reverse causal association effect is observed.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Objective:To explore the genetic etiology of two fetuses with Mosaic variegated aneuploidy syndrome (MVA) in a pedigree.Methods:A 30-year-old pregnant woman, who presented at the Center for Medical Genetics and Prenatal Diagnosis of Shandong Maternal and Child Health Care Hospital on November 16, 2023, was enrolled. Clinical data of the pedigree were collected, and peripheral blood samples from the parents and amniotic fluid samples from the two fetuses were obtained for genomic DNA extraction. Whole exome sequencing (WES) was performed on both fetuses, followed by Sanger sequencing for familial validation and pathogenicity analysis of candidate variants. Chromosomal karyotyping of the parents was conducted to quantify the proportion of premature chromatid separation (PCS). This study was approved by the Medical Ethics Committee of Shandong Maternal and Child Health Care Hospital (Ethics No. 2024-034).Results:① Both fetuses exhibited structural brain anomalies and developmental delays during the second trimester. Amniocyte karyotyping revealed low-level mosaic aneuploidy involving multiple chromosomes, while chromosomal microarray analysis (CMA) showed no abnormalities. Pregnancy termination was performed for fetus 1. ② WES identified compound heterozygous variants in BUB1B — c. 2363_2364del (p.S788Cfs*29) and ss804270619: G>A — in both fetuses. Sanger sequencing confirmed paternal inheritance of c. 2363_2364del and maternal inheritance of ss804270619: G>A. According to the American College of Medical Genetics and Genomics (ACMG) and Clinical Genome Resource(ClinGen) Standards and Guidelines for the Interpretation of Sequence Variants, the c. 2363_2364del variant was classified as likely pathogenic (PVS1 + PM2_Supporting). Parental karyotyping demonstrated PCS traits, with a higher proportion of abnormal metaphases in the father. Conclusion:The compound heterozygous variants c. 2363_2364del (p.S788Cfs*29) and ss804270619: G>A in BUB1B may constitute the genetic etiology of the two MVA fetuses in this pedigree.

Objective:To identify the relevant factors for the first-course remission of acute myeloid leukemia (AML) and to develop a predictive model as well as assess its predictive capability.Methods:Clinical data of 749 patients newly diagnosed with AML admitted to the Department of Hematology, the First Affiliated Hospital, Zhejiang University, School of Medicine from January 1, 2019, to April 30, 2023, were collected and randomly divided into training and validation sets. Multivariate logistic regression analysis was conducted to determine variables associated with complete remission in the first course of induction therapy, and a predictive model was established based on these variables. The receiver operating characteristic (ROC) curve of the predictive model was plotted, and the area under the curve (AUC) was calculated.Results:The indicators predicting the first remission course included peripheral blood white blood cell count during onset, CBF::MYH11 fusion gene, CEBPA bZIP region mutation, myelodysplastic syndrome-related gene mutation, and induction chemotherapy regimen selection as independent factors for the first remission course. The model’s area under the training and validation curves was 0.738 (95% CI: 0.696-0.780) and 0.726 (95% CI: 0.650-0.801), respectively. The Hosmer-Lemeshow test results yielded P-values of 0.993 and 0.335, respectively. Conclusion:In this study, the developed model demonstrates a strong predictive capability for the efficacy of the first course of patients with AML, providing valuable guidance to clinicians in assessing patient prognosis and selecting appropriate treatment strategies.

Objective To investigate the expression changes and clinical significance of serum pepsinogen(PG)and triggering receptor expressed on myeloid cells-1(TREM-1)in patients with reflux esophagitis(RE).Methods A total of 140 patients with RE who were treated from October 2021 to October 2023 were selected as the observation group,and 140 healthy adults who underwent physical examination during the same period were selected as the control group.Serum PG(PGⅠ and PGⅡ)and TREM-1 were detected by ELISA.Multivariate logistic regression was used to analyze the influencing factors of RE.Receiver operating characteristic(ROC)was used to analyze the diagnostic efficacy of serum PGⅠ,PGⅡ and TREM-1 levels for RE.Results The levels of interleukin(IL)-2,IL-6,Il-1β,PGⅡ,TREM-1 and tumor necrosis factor-α(TNF-α)in the observation group were significantly higher than those in the control group,while the level of PGⅠ was significantly lower than that in the control group(P<0.01).Serum IL-2,IL-6,IL-1β,TNF-α,PGⅡ and TREM-1 were risk factors for RE,while serum PGⅠ was a protective factor for RE(P<0.01).ROC curve analysis showed that the area under the ROC curve(AUC)of combined detection of PGⅠ,PGⅡ and TREM-1 in the diagnosis of RE was significantly higher than that of PGⅠ alone(Z=5.940,P<0.001)and PGⅡ alone(Z=6.764,P<0.001)and TREM-1 alone(Z=6.791,P<0.001).Conclusion The expression levels of serum PGⅡ and TREM-1 in patients with RE are increased,while the expression level of PGⅠ is decreased.The combined detection of the three can improve the diagnostic efficacy of RE.
