Changes and significance of plasma fibrinogen gamma‐chain concentration in preeclampsia patients

ObjectiveTo investigate the plasma fibrinogen gamma‐chain concentration in preeclampsia patients and explore its value in preeclampsia prediction and auxiliary diagnosis.MethodsFollow‐up of pregnant women who regularly attended perinatal care at two hospitals in China was performed, and clinical data and plasma samples were collected at each examination until delivery. The gamma‐chain concentration was detected by Western blotting, and Quantity One Software was used for gamma‐chain grayscale value measurements.ResultsForty‐two patients with preeclampsia and 42 control patients completed the follow‐up. In the control group, the gamma‐chain concentration at 32 weeks of gestation was higher than that at 20 weeks of gestation, but the difference was not statistically significant (p > 0.05). In the experimental group, the gamma‐chain concentration at preeclampsia diagnosis was significantly higher than that at 20 weeks of gestation (p < 0.05). Compared with the control group, the gamma‐chain concentration was higher at 20 weeks of gestation in the experimental group, but the difference was not statistically significant. However, at 32 weeks of gestation and at the time of diagnosis, the gamma‐chain concentration in the experimental group was significantly higher than that in the control group (p < 0.05). At 32 weeks of gestation and at the time of diagnosis, the AUCs from ROC curve analysis of plasma fibrinogen gamma‐chain concentrations were 0.64 and 0.71, respectively.ConclusionPlasma fibrinogen synthesis and degradation were disrupted in preeclampsia patients before and after diagnosis, and gamma‐chain concentration was significantly increased. Plasma fibrinogen gamma chain may be of some value in preeclampsia prediction and auxiliary diagnosis.

The prognostic role of serum uric acid levels in preeclampsia: A meta‐analysis

This meta‐analysis aims to compare serum uric acid levels among preeclamptic and healthy pregnant women across the various trimesters and provide a summary of the effect size of this biomarker in predicting adverse pregnancy outcomes. MEDLINE, Scopus, CENTRAL, Clinicaltrials.gov, and Google Scholar databases were systematically searched from inception. Observational studies were held eligible if they reported serum uric acid among preeclamptic and healthy pregnant women. Meta‐analysis was conducted regarding uric acid concentration, diagnostic accuracy, and association with perinatal outcomes. The credibility of evidence was appraised using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. The analysis included 196 studies, comprising 39 540 women. Preeclampsia was associated with significantly elevated uric acid levels during the 1st (mean difference [MD]: 0.21 mg/dL, 95% confidence intervals [CI]: 0.06‐0.35) trimester, 2nd (MD: 1.41 mg/dL, 95% CI: 0.78‐2.05) trimester, and 3rd (MD: 2.26 mg/dL, 95% CI: 2.12‐2.40) trimester. Higher uric acid was estimated for severe preeclampsia, eclampsia, and hemolysis, elevated liver enzymes, low platelet syndrome. The sensitivity for adverse perinatal outcome prediction ranged from 67.3% to 82.7% and the specificity from 47.7% to 70.7%. In conclusion, it is suggested that serum uric acid levels are increased in preeclampsia and can be used to predict disease severity and pregnancy complications. Future prospective studies should verify these outcomes, assess the optimal cutoffs, and incorporate uric acid to combined predicting models.     

早期死亡风险评分对胰腺癌患者术后预后预测的价值

目的探讨早期死亡风险评分(early mortality risk score,EMRS)对胰腺癌患者术后预后的预测价值,寻找胰腺癌术后预后不良的早期预测方法。方法收集就诊并接受根治性手术治疗的370例胰腺癌患者的临床资料,记录患者的性别,年龄,体质指数(BMI),肿瘤部位、大小,合并基础疾病情况,术后生存时间,EMRS评分结果等信息。根据患者术后1年的临床结局(生存,死亡)将患者分为生存组和死亡组。单因素分析法比较组间上述指标的差异,选取单因素分析当中有差异的指标进一步进行Logistic多元回归分析,以确定胰腺癌患者术后预后不良的相关危险因素,并评价EMRS对胰腺癌患者术后预后的预测价值。结果本组370例患者,根据随访1年时的临床结局分为生存组(252例)和死亡组(118例),两组患者平均年龄、性别构成、合并基础疾病、既往吸烟史、近期体重变化、肿瘤分化程度、是否合并淋巴结转移、周围神经转移、血管转移、及术后并发症发生率比较,差异无统计学意义(P0.05);死亡组患者肿瘤相对较大,切缘阳性率、平均EMRS评分较高,组间比较差异有统计学意义(P0.05);且肿瘤大小,切缘阳性率、EMRS评分3项指标进行多元Logistic回归分析,结果显示,该3项指标均为胰腺癌患者术后早期预后不良的独立危险因子(OR均1.0,P均0.05);在EMRS=3.0时,其预测患者术后早期预后不良的敏感性和特异性分别为77.4%和82.3%。结论 EMRS与胰腺癌患者术后早期预后有关,高EMRS评分是胰腺癌患者术后早期预后不良的独立危险因子,EMRS评分3时,其预测胰腺癌患者术后早期预后不良的敏感性和特异性均较高。

Computed tomography and clinical parameters predict intracerebral hemorrhage expansion

This study aimed to evaluate the association of imaging signs, and to establish a predictive model through selecting highly relevant imaging signs in combination with clinical parameters for hematoma expansion.Intracerebral Hemorrhage (ICH) patients who received 2 consecutive noncontrast computed tomography scans were examined and recruited through January 2014 to December 2020. Demographic information and clinical characteristics were collected. Two experienced radiologists reviewed baseline noncontrast computed tomography images to assess the imaging characteristics. Correlation analysis was analyzed with Pearson and Spearman correlation tests. The association between clinical and imaging predictors with hematoma expansion was evaluated in multivariate models. Receiver operating characteristic (ROC) curve analysis was adopted to evaluate predictive performance.A total of 232 ICH patients, with mean age of 59.73 years, and 31% of female were included, among which, 32 patients occurred with hematoma expansion. For sex, ICH density, low density in hematoma, the midline shift, and Glasgow Coma Scale score, liquid level, H-tra, edema Cor, H Volume, time from onset to examination, there were significant differences between the 2 groups. As for imaging signs, only blend sign showed a significant difference, that patients with blend sign had a higher incidence of ICH expansion. The logistic analysis found that radiation attenuation, liquid level, the midline shift, Glasgow Coma Scale score, history of ischemic stroke, and smoking could predict the occurrence of ICH expansion.In summary, the model combined radiological characteristics with clinical indicators showed considerable predictive performance. Further validation is needed to verify the findings and help transfer to clinical practice.

早期急性重症胰腺炎预后因素分析

Objective Analysis of early risk predict markers within 24h after admission of prognosis in severe acute pancreatitis (SAP). Methods Medical records of 127 patients with sever acute pancreatitis admitted to our hospital within 72h after onset from February 2006 to July 2009 were retrospectively analyzed. These inpatients were grouped into survival group (102 cases) and death group (25 cases). The clinical and laboratory data within 24h after admission were compared between two groups. Results Compared with survival group, patients in death group had significantly difference in heart rate, respiratory, PaO2, pH value, serum calcium, serum kalium, serum creatine, BUN, BE, LDH, serum albumin and APCHE Ⅱscores (P<0.05). Higher APCHE Ⅱ scores after admission was an independent early high risk predicator of death. Conclusions Death group was characterized as severe multiple organ dysfunction and severe internal disturbance. Heart rate, respiratory, PaO2, pH value, serum calcium, serum potassium, serum creatine, BUN, BE, LDH, serum albumin and APCHE Ⅱ scores were early risk predict markers of death in patients with sever acute pancreatitis.
