Objective:To identify the risk factors of venous thromboembolism (VTE) in postoperative renal transplantation recipients by Meta-analysis, and to provide evidence-based reference for clinical staff to develop early VTE prevention strategies.Methods:PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure, VIP database, Wanfang database and Chinese Biomedical Literature Database were searched to collect the studies on the risk factors of postoperative VTE in kidney transplant recipients. The search period was from the establishment of the database to March 10, 2024. After literature screening, data extraction and quality evaluation were conducted independently by two researchers, Meta-analysis was performed using RevMan 5.3 software.Results:A total of 15 literatures with 20 influencing factors were included. Meta-analysis showed that age ( MD = 6.36, 95% CI 2.56-10.17, P<0.05), body mass index ( MD = 1.83, 95% CI 0.15-3.50, P<0.05), VTE history ( OR = 2.04, 95% CI 1.08-3.86, P<0.05), blood transfusion history ( OR = 3.77, 95% CI 2.43-5.83, P<0.05), glomerular filtration rate ( MD = -5.54, 95% CI -9.93 - -0.91, P<0.05), donor age ( MD = 3.18, 95% CI 1.10-5.25, P<0.05), combination of malignant tumor ( OR = 2.87, 95% CI 1.45-5.68, P<0.05), end-stage renal disease as polycystic kidney disease ( OR = 1.76, 95% CI 1.39-2.22, P<0.05), and interstitial nephritis ( OR = 1.60, 95% CI 1.06-2.40, P<0.05) were the influencing factors for postoperative VTE in renal transplant recipients. Conclusions:Clinical medical staff should actively identify high-risk groups for VTE after kidney transplantation by considering the 8 influencing factors determined by this study, and take targeted measures early to reduce the risk of postoperative VTE.

Objective:To investigate the predictive value of refeeding syndrome (RFS) and its influencing factors for 30-day intensive care unit (ICU) readmission in critically ill patients.Methods:A prospective cohort study was conducted. Critically ill patients admitted to the department of critical care medicine, department of respiratory and critical care medicine, and department of neurology at Tianjin Medical University General Hospital from January to April in 2025 were enrolled. Patients were assessed for RFS according to the American Society for Parenteral and Enteral Nutrition (ASPEN) criteria. General information within 24 hours of ICU admission was collected via the electronic medical record system. Treatment details and 30-day ICU readmission status were dynamically recorded. Participants were divided into readmission and non-readmission groups based on whether ICU readmission occurred within 30 days. Intergroup comparisons were performed to identify differences. Multivariate Logistic regression was used to analyze the relationship between RFS and its influencing factors with 30-day ICU readmission. Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive performance of risk factors.Results:A total of 196 critically ill patients were enrolled, among whom 25 (12.76%) were readmitted to ICU within 30 days and 171 (87.24%) were not. Significant differences were observed in the readmission group compared with the non-readmission group, including significantly higher rates of nasogastric decompression, higher acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, a higher incidence of RFS, and a longer duration of nasogastric decompression. Multivariate Logistic regression analysis showed that RFS was an independent risk factor for 30-day ICU readmission [odds ratio ( OR) = 5.756, 95% confidence interval (95% CI) was 1.603-20.670, P = 0.007]. APACHEⅡ score showed a positive correlation trend with 30-day ICU readmission ( OR = 1.057, 95% CI was 0.991-1.127, P = 0.092). ROC curve analysis showed that the combined prediction model incorporating RFS and APACHEⅡ score had an area under the ROC curve (AUC) of 0.766 (95% CI was 0.668-0.864), with a sensitivity of 88.0% and a specificity of 62.0%, which was significantly superior to a single indicator (the AUC of RFS and APACHEⅡ score was 0.639 and 0.624, respectively). Conclusions:RFS significantly increases the risk of 30-day ICU readmission in critically ill patients. A combined model incorporating RFS and APACHEⅡ score demonstrates good predictive efficacy for 30-day ICU readmission in critically ill patients.

A retrospective case review was conducted of 3 cases with umbilical venous catheterization(UVC) related pericardial effusions in the Neonatal Intensive Care Unit of Zhongnan Hospital of Wuhan University from December 2020 to April 2022.All 3 cases were preterm infants with gestational ages of 33 + 4, 31 and 27 + 6 weeks, respectively.UVC was inserted routinely in 24 hours after birth.Three neonates developed tachycardia or bradycardia, dyspnea, decreased oxygen saturation and muffled heart sound at the 1 st to 4 th day after catheterization.Echocardiography indicated pericardial effusion, so the 3 neonates underwent pericardiocentesis and drainage.Among the 3 neonates, 2 cases improved and have good prognosis, 1 case died.UVC can cause pericardial effusion, which occurs mostly in the early stage after catheterization.Pericardial effusion and tamponade should be considered when patients show unexplained sudden clinical deterioration after catheterization, such as dyspnea, cyanosis, tachycardia or bradycardia, etc.Once diagnosed, umbilical vein catheter should be removed in time and pericardiocentesis and drainage should be performed for decompression.Early diagnosis and intervention can effectively improve the prognosis.

Objective:To initially investigate whether simultaneous radiochemotherapy with hyperthermia can prolong the survival of glioblastoma (GBM) patients.Methods:Clinical data of 61 GBM patients undergoing surgery in our hospital from September 2016 to June 2019 were retrospectively analyzed. According to different treatment methods, all patients were divided into the control group ( n=34) and observation group ( n=27). In the control group, three-dimensional radiotherapy with a dose of 60 Gy combined with temoazolamine chemotherapy was delivered. In the observation group, simultaneous radiochemotherapy with 15-20 cycles of hyperthermia at 40-41℃ was supplemented. The survival time was calculated by Kaplan-Meier method, and the survival time was compared with log-rank test between two groups. Results:The median progression-free survival in the observation group was significantly longer than that in the control group (14.33 months vs.9.94 months, P<0.05). The median overall survival in the observation group was also remarkably higher than that in the control group (18 months vs. 14 months, P<0.05). Conclusions:Simultaneous radiochemotherapy with hyperthermia is innovatively applied to treat GBM after surgical resection. Preliminary findings demonstrate that compared with chemoradiotherapy, simultaneous radiochemotherapy with hyperthermia can prolong the survival time of GBM patients.

Objective:To analyze the clinical, genetic characteristics and follow-up data of Chinese patients with hypophosphatasia (HPP).Methods:A retrospective analysis was conducted on six children with HPP admitted to the Department of Endocrinology, Genetics and Metabolism in Beijing Children′s Hospital from October 2010 to January 2019. Summarized the clinical and follow-up data of all six patients, as well as the pathogenic variants of five children.Results:The serum alkaline phosphatase levels of all six children (five males and one female) were significantly reduced (2-49 U/L). The 6 patients aged from 2 months to 6 years and 4 months, 4 infantile HPP, 1 childhood HIP and 1 odonto HPP. The four patients with infantile HPP presented with anorexia, slow weight gain and hypercalcemia, whereas the one patient with childhood HPP and the other patient with odonto HPP had tooth loss. The patient with childhood HPP also manifested with motor dysfunction. Genetic testing was conducted for five patients and 4 unrelated Chinese families and revealed 10 variations in ALPL gene, including 7 missense variation, 1 insertion variation, 1 frameshift variation, 1 deletion variation.Of which 3 were novel (p.Y28C, p.268, F>L, p.A176V).One of the infantile patients lost follow-up and the other three deceased. The clinical conditions were much improved with medical intervention for patients with childhood, orodonto HPP.Conclusions:While HPP patients with different ages of onset present with common features, the prognosis differ significantly. The prognosis is good for patients with childhood, orodonto HPP and poor for patients with infantile HPP. Genetic testing is the main method for definitive diagnosis.

Objective:To explore the correlation between the expression levels of serum estradiol and otolin-1 and the recurrence of postmenopausal benign paroxysmal positional vertigo (BPPV).Methods:A total of 116 postmenopausal female patients who were diagnosed with primary BPPV in the Vertigo Treatment Center of Beijing Geriatric Hospital from January 2018 to December 2019 were selected as the research objects. They were divided into recurrence group (27 cases) and the non-recurrence group (89 cases) according to the recurrence during follow-up. The basic data, laboratory indexes and complications of the two groups were compared. The serum estradiol level was detected by electrochemiluminescence and the serum otolin-1 level was detected by enzyme-linked immunosorbent assay. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum estradiol and otolin-1 in the recurrence of postmenopausal BPPV patients; Multivariate logistic regression was used to analyze the risk factors of recurrence in postmenopausal BPPV patients.Results:The proportion of severe cough in the recurrence group was higher than that in the non-recurrence group ( P<0.05); the level of estradiol in the recurrence group was significantly lower than that in the non-recurrence group ( P<0.05), and the level of otolin-1 was significantly higher ( P<0.05); ROC results showed that the areas under the curve (AUCs) of serum estradiol and otolin-1 for predicting the recurrence of postmenopausal BPPV patients were 0.852 (95% CI: 0.774-0.911) and 0.722 (95% CI: 0.631-0.801) respectively, and the cut-off values were 18.09 pg/ml and 361.79 pg/ml respectively; Multivariate logistic regression analysis showed that severe cough, estradiol ≤18.09 pg/ml, and otolin-1 >361.79 pg/ml were independent risk factors for recurrence in postmenopausal BPPV patients ( P<0.05). Conclusions:The serum estradiol level of patients with postmenopausal BPPV recurrence decreases, and the level of otolin-1 increases. The abnormal level is an independent risk factor affecting the recurrence of patients with postmenopausal BPPV.
