RESUMO
Objective To explore the impact factors on early neurological deterioration(END)in patients with cerebral infarction combined with coronavirus disease 2019(COVID-19).Methods The clinical characteristics and laboratory of patients with acute ischemic stroke and COVID-19 in Brain Hospital Affiliated to Nanjing Medical University were retrospectively analyzed from December 15,2022 to January 15,2023.According to whether or not END occurred,all patients were divided into END group and non-END group.The clinical data of two groups were analyzed.Results A total of eligible 56 patients were included in this study,with 16 cases in END group and 40 cases in non-END group.The average age of END group(74.31±12.04)was older than non-END group(67.18±8.15)(P<0.05).The proportion of previous history of coronary heart disease and diabetes were higher than non-END group(all P<0.05).In terms of laboratory examination,the number of monocytes,C-reactive protein,glycated hemoglobin,lactate dehydrogenase,myoglobin,albumin,D-dimer,and fibrin degradation products in END group were significantly higher than that in non-END group(all P<0.05).Logistic analysis showed that C-reactive protein is an independent risk factor for cerebral infarction combined with COVID-19(OR =1.084,95%CI:1.002-1.173,P<0.05).Area under the ROC curve was0.825(95%CI:0.709-0.941,P<0.001).Conclusions For patients with cerebral infarction combined with COVID-19,early neurological deterioration is more likely to occur in elderly patients with multiple underlying diseases,abnormal coagulation and inflammation indicators.Increased C-reactive protein has good predictive ability.
RESUMO
Objective To investigate the influencing factors of peripheral infections of knee joint tumor prosthesis as well as the value of serum D-D and TLR2 in predicting the infection risks so as to provide a reference for early diagnosis of tumorous periprosthetic infection(PJI)of knee joint.Methods The patients who were treated and followed up in our department from January 2008 to June 2020 were selected.According to the inclusion and exclusion criteria,136 of the patients were selected.The data including age,gender,BMI,history of diabetes,smoking history,tumor location,stage of malignant tumor,operation time,osteotomy length,intraoperative bleed-ing,and the percentage of neutrophils,leukocytes,serum D-dimer,and serum TLR value 3 days after operation were collected.The risk factors of PJI and the diagnostic value of serum D-dimer and serum TLR were analyzed.Results The incidence of PJI was 11.76%.Postoperative chemotherapy and operation time≥180 min were the risk factors of PJI(P<0.05).The area under curve(AUC)of the combination of two indicators,serum D-dimer and serum TLR2 were 0.917,0.894 and 0.778,respectively.The AUC of TLR2 was lower than that of the combina-tion of two indicators(P<0.05);The sensitivity was 0.975,0.908 and 0.708,respectively,and the specificity was 0.75,0.75,and 0.812,respectively.Conclusion Postoperative chemotherapy and operation time≥180 min are the risk factors of PJI.The combination of D-dimer and TLR2 has good diagnostic value.
RESUMO
Objective To investigate the predictive value of serum thrombospondin-1(THBS-1),D-dimer(D-D)and tissue inhibitor of metalloproteinase-1(TIMP-1)levels in late pregnancy for postpartum hemorrhage(PPH)in re-pregnant women with scarred uterus.Methods Totally 108 re-pregnant women with scarred uterus admitted to the First Affiliated Hospital of Xinxiang Medical University from June 2020 to August 2022 were selected and divided into the PPH group(n=21)and the non-PPH group(n=87)according to whether PPH occurred after delivery.On the day of admission,5 mL elbow venous blood was collected from re-pregnant women in the two groups,and the levels of serum THBS-1,D-D and TIMP-1 of pregnant women in the two groups were detected by enzyme-linked immunosorbent assay.The serum THBS-1,D-D TIMP-1 levels and clinical data of pregnant women between the two groups were compared.The influencing factors on the occurrence of PPH in re-pregnant women with scarred uterus were analyzed by multivariate logistic regression,and the predictive value of serum THBS-1,D-D and TIMP-1 levels on the occurrence of PPH in re-pregnant women with scarred uterus was evaluated by receiver operating characteristic curve.Results The percentage of patients with ≥ 2 induced abortions,placental abruption,uterine incision laceration,uterine inertia or scar thickness<0.3 cm,as well as serum THBS-1 and D-D levels in late pregnancy in the PPH group were significantly higher than those in the non-PPH group,and serum TIMP-1 level in late pregnancy were significantly lower than that in the non-PPH group(P<0.05).The uterine inertia,as well as high D-D and THBS-1 levels,were independent risk factors for PPH in re-pregnant women with scarred uterus(P<0.05),and low TIMP-1 level was a protective factor(P<0.05).The area under the curve of combined serum THBS-1,D-D and TIMP-1 levels to predict PPH in re-pregnant women with scarred uterus was greater than that predicted by the three factors alone(P<0.05).Conclusion Serum THBS-1,D-D and TIMP-1 levels in late pregnancy can be used as reference indicators for predicting the occurrence of PPH in re-pregnant women with scarred uterus,and the combination of the three indexes is more effective in predicting the occurrence of PPH.
RESUMO
Background The novel coronavirus infection is widespread in the world, resulting in more pneumoconiosis patients complicated with coronavirus disease 2019 (COVID-19). Objective To understand the clinical characteristics and prognosis of hospitalized COVID-19 patients complicated with or without pneumoconiosis. Methods A total of 36 COVID-19 patients admitted to the Shandong Provincial Occupational Disease Hospital from 10 December to 31 December 2022 were selected, including 21 cases in the complication group (pneumoconiosis complicated with COVID-19) and 15 cases in the COVID-19 group without pneumoconiosis. Symptoms, signs, laboratory test results(e.g. routine blood test), imaging findings, treatment plans and prognosis of the two groups were observed and compared. Results Regarding symptoms and signs in the complication group and the COVID-19 group, the proportions of dyspnea (57.14% vs 0.00%), lung wheezing (28.57% vs 0.00%), wet rales (76.19% vs 33.30%), and fever (61.90% vs 93.33%) were significantly different (P<0.05). Compared with the COVID-19 group, the level of D-dimer in the complication group was significantly increased [2.340 (1.0, 6.5) mg·L−1 vs 0.250 (0.2, 0.4) mg·L−1] (P<0.01), the serum sodium level was decreased [(138.10±2.68) mmol·L−1 vs (140.47±2.27) mmol·L−1] (P<0.05). In terms of drug treatment and prognosis, there were statistically significant differences in the proportion of antiviral drugs (19.00% vs 80.00%), glucocorticoids (38.10% vs 80.00%), and anticoagulants (28.60% vs 0.00%) between the complication group and the COVID-19 group (P<0.05). Compared with the COVID-19 group, the cure rate of the complication group (90.50% vs 100.00%) showed no statistical difference. However, there were 2 deaths in the complication group. Conclusion Patients with pneumoconiosis complicated with COVID-19 have less fever and more dyspnea, wheezing, and wet rales. The increase of plasma D-dimer is a potential predictor in patients with pneumoconiosis complicated with COVID-19.
RESUMO
Objective:To investigate the predictive value of preoperative D-dimer level for futile recanalization (FR) after mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS).Methods:It was a nested case-control study. A total of 116 patients with large vessel occlusion (LVO) stroke, who underwent successful recanalization (modified Thrombolysis in Cerebral Infarction, mTICI≥2b) after MT at the Stroke Unit of Beijing Hospital from August 2018 to January 2022,were consecutively enrolled, including 72 males (62.1%) with the age of (72.8±13.1) years. According to the 3-month modified Rankin Scale (mRS) score after MT, patients were divided into the meaningful recanalization group (mRS 0-2, n=41) and the futile recanalization group (mRS 3-6, n=75). The baseline clinical data of enrolled patients was collected. Logistic regression analysis was used to identify the independent risk factors for FR after MT in patients with AIS. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of D-dimer for FR. Results:Multivariate logistic regression analysis showed that high baseline systolic blood pressure (SBP) ( OR=1.038, 95% CI: 1.012-1.065, P=0.004), baseline National Institutes of Health Stroke Scale (NIHSS) score≥12 ( OR=10.157, 95% CI: 3.624-28.470, P<0.001) and high preoperative D-dimer level ( OR=4.536, 95% CI: 1.379-14.922, P=0.013) were independent predictors of FR after MT in AIS patients with LVO. ROC curve analysis indicated a good predictive value of preoperative D-dimer for the occurrence of FR ( AUC=0.733, 95% CI: 0.638-0.829, P<0.05), the optimal cut-off value of D-dimer was 2.65 μg/L(Lg), with the Youden index, sensitivity, specificity and accuracy of 0.435, 53.3%, 90.2% and 66.4%, respectively. Conclusion:High preoperative D-dimer level is an independent predictor of futile recanalization after MT in AIS patients with LVO, which shows good predictive ability for futile recanalization.
RESUMO
D-dimer is a fibrin degradation product. The increased D-dimer indicates hypercoagulability and secondary hyperfibrinolysis, which can be used as a biomarker for activation of coagulation and fibrinolysis system. D-dimer is routinely used in the diagnosis of thrombotic diseases. D-dimer level is affected by age, pregnancy, blood glucose, infection, liver failure, cancer and stroke. The increased D-dimer is closely related to kidney diseases. The paper reviews the formation mechanism and influencing factors of D-dimer, the relationship between D-dimer and kidney diseases, and the prognostic value of D-dimer in kidney diseases, to provide references for clinical diagnosis and treatment.
RESUMO
Introducción: La pandemia de COVID-19 continúa desafiando a los sistemas de salud. La estratificación de los pacientes afectados a partir de biomarcadores, estrategia menos invasiva, aún es controversial. Objetivo: Comprobar la capacidad discriminante de la ferritina, proteína C reactiva y dímero D entre pacientes con COVID-19 moderados y severos. Métodos: Se aplicó un diseño transversal entre junio y noviembre de 2021. Las variables cualitativas y la edad fueron registradas por revisión de la historia clínica. La determinación de los biomarcadores mencionados fue realizada en el momento de inclusión en el estudio con el empleo de reactivos Roche en el analizador Hitachi cobas c 311. Se empleó el programa estadístico SSPS para el análisis de datos. Resultados: Existió predominio de hipertensos en ambos grupos. La vacunación y el sexo femenino prevalecieron entre los moderados, mientras los hombres y las enfermedades crónicas entre los graves. Se manifestaron mayores niveles de los tres biomarcadores analizados en el grupo grave (Mann-Whitney p 0,5; p < 0,05). Conclusiones: La presencia de comorbilidades crónicas y de individuos no vacunados predominó entre los pacientes graves. Se demostró una estrecha correlación entre los biomarcadores analizados en ambos grupos de pacientes. Los biomarcadores mostraron capacidad discriminante entre la enfermedad COVID-19 moderada y grave.
Introduction: The COVID-19 pandemic continues to challenge healthcare systems. The stratification of affected patients from biomarkers, a less invasive strategy, is still controversial. Objective: To check the discriminating capacity of ferritin, C-reactive protein and D-dimer in patients with moderate and severe COVID-19. Methods: A cross-sectional design was applied from June to November 2021. The qualitative variables and age were recorded by review of the patient's clinical records. The determination of the aforementioned biomarkers was carried out at the time of inclusion in the study using the Roche reagents in the HITACHI Cobas C 311 analyzer. The SPSS statistical program was used for analyzing dates. Results: There was a predominance of hypertensive patients in both groups. Vaccination and female sex prevailed among the moderate ones, while men and chronic diseases among the severe ones. Higher levels of the three analyzed biomarkers were observed in the severe group (Mann-Whitney test p < 0.05). The association between these was significant in both groups (Spearman correlation, p < 0.05). 366 μg/L of ferritin; 36.25 mg/L of C- reactive protein and 1.02 μg/mL of D-dimer, acceptably distinguished between severe and moderate (area under the curve ˃ 0.5; p < 0.05). Conclusions: The presence of chronic comorbidities and unvaccinated individuals predominated among severe patients. A close correlation was shown between the biomarkers analyzed in both patient groups. Biomarkers showed discriminating capacity between moderate and severe COVID-19 disease.
RESUMO
Décrire les aspects épidémio-cliniques des manifestations thrombotiques au cours de la COVID-19 au sein des hôpitaux militaires de Libreville et Akanda, Gabon. Méthodes : Nous avons mené une étude rétrospective et descriptive multicentrique d'une durée de 7 mois, du 01er septembre 2021 au 31 mars 2022, portant sur les patients admis dans les unités de réanimation des hôpitaux d'instruction des armées de Libreville (HIAOBO) et d'Akanda (HIAA), pour COVID-19 documentée ou suspectée. Résultats : Durant la période d'étude, 167 patients ont étéÌ admis pour infection à SARS-CoV-2, parmi lesquels, 18 ont présentés des manifestations thromboemboliques (10,8%). La moyenne d'âge était de 54,7±6.4 ans. Il y avait une large prédominance masculine avec un sexe ratio à 2. Nous avons notéÌ 9 cas d'embolie pulmonaire (50%), 5 cas d'accidents vasculaires cérébraux ischémiques (28%), 1 cas de thrombose veineuse profonde de membre inferieur (6%), 1 cas de thrombose veineuse cérébrale (6%), 1 cas de thrombose de la veine mésentérique (6%) et 1 cas de thrombose de la veine porte (6%). Les D-dimères étaient élevés chez tous les patients. Les globules blancs étaient élevés (>10000/mm3 ) chez 12 patients (67%). Les plaquettes étaient inférieures à 150000/mm3 pour 6 patients (33%). Tous les patients avaient une pneumonie à SARS-CoV-2 et la moyenne d'atteinte deslésions pulmonaires était estimée à 45%. Neuf patients étaient décédés (50%) au cours de l'hospitalisation. Conclusion : L'infection par le SARS-CoV-2 constitue vraisemblablement une prédisposition à la survenue d'un événement thrombotique. L'incidence des manifestations thrombotiques chez les patients atteints de COVID-19 reste élevée, renforçant ainsi la prescription systématique d'une anticoagulation prophylactique

Objective:To investigate the clinical significances of evaluation indexes of right heart function injury in patients with BCR-ABL-negative myroproliferative neoplasms (MPN).Methods:The clinical data of 208 patients with BCR-ABL-negative MPN diagnosed in the Second People's Hospital of Lianyungang and Jiangsu Province Hospital from January 2015 to August 2021 were retrospectively analyzed, including 63 cases of primary myelopathic fibrosis (PMF), 39 cases of polycytosis vera (PV) and 106 cases of essential thrombocythemia (ET). The clinical characteristics of patients and the examination results of hematological related indicators were compared among the three groups. The examination results of indexes of right heart function injury were analyzed, including echocardiography, brain natriuretic peptide, soluble growth stimulation expression gene-2 (sST-2), lactate dehydrogenase (LDH), D-dimer, ferritin, β 2-microglobulin, peripheral blood WT1 gene, CD34 + cell count, etc. Results:Of the 208 patients, 109 were male and 99 were female; the median age was 62 years old (23 years old, 89 years old). The differences in levels of hemoglobin, platelet count, D-dimer, LDH and ferritin among PMF, PV and ET patients were statistically significant (all P < 0.05). Color echocardiography was performed in 87 patients, including 26 cases of PMF, 19 cases of PV and 42 cases of ET. Pulmonary artery pressure increased in 69 cases (79.3%), left atrial diameter increased in 76 cases (87.3%), and diameter increased during right ventricular diastolic period in 59 cases (67.8%). There were significant differences in pulmonary artery pressure, left atrial diameter and diameter during right ventricular diastolic period among PMF, PV and ET patients (all P < 0.05). Pearson correlation analysis showed that pulmonary artery pressure was positively correlated with ferritin, LDH, sST-2 and age ( r values were 0.796, 0.768, 0.915 and 0.734, all P<0.05), while it was negatively correlated with platelet count ( r = -2.330, P = 0.034). Conclusions:For BCR-ABL-negative MPN patients, the increase of pulmonary artery pressure, ferritin and LDH and the decreased platelet count and hemoglobin may increase the probability of right heart function impairment. For BCR-ABL-negative MPN patients with the higher levels of ferritin, LDH, sST-2, age, and the lower level of platelet count, the pulmonary artery pressure may be higher.
RESUMO
Objective:To investigate the related risk factors affecting the prognosis of hemorrhagic fever with renal syndrome(HFRS) in children.Methods:A retrospective study was carried out.We selected 182 pediatric patients who met the diagnostic criteria for pediatric HFRS while hospitalized in the Intensive Care Department of the Affiliated Children′s Hospital of Xi′an Jiaotong University between July 2014 and December 2021 as the research objects.The severe and critical patients were taken as the observation group(24 cases), and the mild and moderate pediatric patients were taken as the control group(158 cases). The demographic, epidemiological data and clinically relevant indicators within 8 hours of pediatric patients after admission were collected.The 28-day death was the primary endpoint.Renal failure and pulmonary edema were secondary endpoint.The differences of clinically relevant indicators between the two groups were observed.Logistic regression was used to analyze the risk factors and receiver operating characteristic(ROC) curve was used to determine the predictive efficacy of different outcome prediction models.Results:There were no statistically significant differences in age, gender, and BMI between the two groups (all P>0.05). Compared the control group with the observation group, coagulation function indicators such as activated partial thromboplastin time (APTT)[(134±21)s vs.(164±34)s], D-dimer [(6.31±3.20)mg/L vs.(12.43±5.67)mg/L], von Willebrand factor (vWF)[(352±45)μg/L vs.(465±103)μg/L], and platelet(PLT)[(87±35)×10 9/L vs.(45±24)×10 9/L], Lactate(Lac)[(2.6±1.1)mmol/L vs.(6.0±2.0)mmol/L]were different significantly(all P<0.05). Additionally, the lymphocyte characteristic analysis indicator lymphocytes [(2 749±686)×10 6/L vs.(2 374±851)×10 6/L], CD3 + [(1 821± 487)×10 6/L vs.(1 065±539)×10 6/L], CD4 + /CD8 + (1.65±0.73)vs.(1.00±0.25), CD19 + [(559±105)×10 6/L vs.(487± 133)×10 6/L]were different significantly(all P<0.05). The inflammatory index procalcitonin(PCT) [(22±15)ng/L vs.(56±21)ng/L, P<0.05]was different significantly in two groups.The rate of continuous renaly replacement therapy, ventilator-assisted ventilation, vasoactive drugs and other treatment measures increased significantly in observation group than those in control group(all P<0.05). Multivariate logistic regression analysis was performed on the included indicators.With death as the primary endpoint, Lac, CD8 + , D-dimer, vWF and PCT were significantly associated with mortality, which were risk factors for death, while PLT and CD4 + /CD8 + were protective factors.With renal failure and pulmonary edema as secondary endpoint, CD8 + , D-dimer, Lac and PCT were risk factors for secondary endpoint.ROC curve analysis showed that the sensitivity, specificity and AUC of the risk factor prediction model related to the primary endpoint variables were 77.91%, 81.22% and 0.769, and which related to secondary endpoint variables were 87.61%, 77.59% and 0.891, respectively. Conclusion:The combinations of CD8 + , D-dimer, Lac, PCT and vWF have good predictive value for poor prognosis in children with HFRS.
RESUMO
Objective To investigate the predictive value of serum human chorionic gonadotropin(HCG),D-dimer and granulocyte colony-stimulating factor(G-CSF)levels for pregnancy outcome in patients with re-current implantation failure(RIF).Methods A total of 80 RIF patients who underwent in vitro fertilization-embryo transfer in this hospital from May 2019 to May 2022 were selected as the research objects.According to the occurrence of adverse pregnancy outcomes,they were divided into a good pregnancy outcome group(48 cases)and a poor pregnancy outcome group(32 cases).The levels of serum HCG,D-dimer and G-CSF in RIF patients at different pregnancy stages(the day of pregnancy test,the first trimester,the second trimester and the third trimester)were detected.Spearman correlation was used to analyze the correlation between serum levels of HCG,D-dimer,and G-CSF and pregnancy outcomes.Multivariate Logistic regression was used to an-alyze the influencing factors of pregnancy outcome in patients with RIF.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of serum HCG,D-dimer and G-CSF levels for pregnancy outcome in patients with RIF.Results Adverse pregnancy occurred in 32 cases of 80 patients with RIF,and preterm birth and intrauterine distress were the most common adverse pregnancy outcomes.The RIF patients with different stages of pregnancy serum HCG levels gradually decreased,serum D-dimer,G-CSF level in-creased(P<0.05).At different stages of pregnancy,the level of serum HCG in the poor pregnancy outcome group was lower than that in the good pregnancy outcome group(P<0.05),and the levels of serum D-dimer and G-CSF were higher than those in the good pregnancy outcome group(P<0.05).The level of serum HCG was negatively correlated with the adverse pregnancy outcome(r=-0.506,P<0.05),and the levels of ser-um D-dimer and G-CSF were positively correlated with the adverse pregnancy outcome(r=0.498,0.542,P<0.05).Multivariate Logistic regression analysis showed that HCG,D-dimer and G-CSF levels were the influ-encing factors of poor pregnancy outcome in patients with RIF(P<0.05).Serum HCG,D-dimer,G-CSF pa-tients with single and combined forecast RIF area under the curve of the pregnancy outcomes were 0.877,0.947,0.911 and 0.971,the sensitivity were 88.10%,88.10%,90.48%and 95.24%respectively,the specific-ity were 81.58%,97.37%,76.32%and 89.47%,respectively.The combined detection of the three markers could improve the prediction efficiency(P<0.05).Conclusion The combined detection of serum HCG,D-di-mer and G-CSF levels can effectively predict the pregnancy outcome of patients with RIF.
RESUMO
Objective:To explore the correlation of serum adiponectin (APN) , D-dimer (D-D) and neutrophil-to-lymphocyte ratio (NLR) levels with disease severity and prognosis in patients with diabetic foot ulcer infection.Methods:92 patients with diabetic foot ulcer infection in the Nantong Third Hospital Affiliated to Nantong University from Feb. 2020 to Feb. 2021 were selected, and they were divided into mild ( n=30) , moderate ( n=44) and severe ( n=18) patients according to the severity of the disease. The serum APN, D-D and NLR levels in patients with different severity were compared, the relationship between serum APN, D-D and NLR levels and disease severity in patients with diabetic foot ulcer infection were analyzed. Patients were followed up for 1 year, and the prognosis of the patients was counted. Factors affecting serum APN, D-D and NLR levels in patients with diabetic foot ulcer infection were analyzed, and the receiver operating curve (ROC) was used to analyze the value of serum APN, D-D and NLR levels in predicting poor prognosis of patients. Results:There were significant differences in serum APN, D-D and NLR levels in patients with different severity ( P<0.05) . APN level in severe patients was 5.35±0.98, in moderate patients was 7.64±1.25, both lower than that of the mild patients 9.19±1.73 ( P<0.05) . Serum APN level in severe patients was lower than that in moderate patients ( P<0.05) . Serum D-D and NLR levels were 3.49±0.72 and 2.86±0.58 in severe patients, respectively; and they were 3.02±0.63 and 2.24±0.46 in moderate patients, higher than that of mild patients 2.43±0.51; 1.71±0.33 ( P<0.05) . The levels of serum D-D and NLR in severe patients were higher than those in moderate patients ( P<0.05) . Spearman correlation analysis showed that the severity of the disease was negatively correlated with serum APN levels ( r=-0.414, P<0.001) , and positively correlated with serum D-D and NLR levels in patients with diabetic foot ulcer infection ( r=0.387, P<0.001; r=0.461, P<0.001) . Univariate analysis showed that the proportion of severe disease, serum fasting blood glucose, glycosylated hemoglobin, fibrinogen, D-D and NLR levels in patients with poor prognosis were higher than those in patients with good prognosis ( P<0.05) , and the APN level in patients with poor prognosis was lower than that in patients with good prognosis ( P<0.05) . Logistic multivariate regression analysis showed that severe disease, serum glycosylated hemoglobin, APN, D-D, and NLR levels were independent risk factors for poor prognosis in patients with diabetic foot ulcer infection ( P<0.05) . ROC analysis showed that the optimal cut-off points of serum APN, D-D and NLR levels for predicting poor prognosis of patients were 5.73 mg/L, 3.06 mg/L, 2.12, the sensitivity was 78.57%, 82.14%, 85.71%, the specificity was 76.56%, 67.19%, 73.44%, the area under the curve (AUC) was 0.793, 0.784, 0.818, the specificity and AUC of the three were 98.44 %, 0.918, respectively. Conclusions:Serum APN, D-D and NLR levels are related to the severity of the disease in patients with diabetic foot ulcer infection. Clinical detection of serum APN, D-D and NLR levels can be used as sensitive indicators to predict poor prognosis.
RESUMO
Objective:To explore the clinical characteristics of patients with colchicine poisoning, and analyze the risk factors affecting the prognosis of colchicine poisoning and its value in the prognostic assessment.Methods:Patients with colchicine poisoning admitted to the Emergency Intensive Care Unit of the First Affiliated Hospital of Wenzhou Medical University from December 2017 to October 2022 were retrospectively included and divided into the survival group and death group according to the 14-d outcome. The general conditions of the two groups of patients were compared, and the clinical characteristics of patients with colchicine poisoning were analyzed. The differences of laboratory indexes, electrocardiogram, cardiac ultrasound and other clinical indexes during the first admission of patients between the two groups were compared, and their value in the prognosis evaluation of patients with colchicine poisoning was explored.Results:There were 41 patients with colchicine poisoning, aged 15-85 years, including 35 males and 6 females. There were 27 patients (65.9%) in the survival group and 14 patients (34.1%) in the death group, including accumulative poisoning (58.7%) and suicide poisoning (41.3%). The main clinical manifestations of patients with colchicine poisoning were gastrointestinal symptoms (82.93%), multiple organ dysfunction (78.05%), infectious fever (73.17%), myocardial damage (48.78%), coagulation dysfunction (46.34%), and bone marrow suppression (41.46%). Intestinal obstruction (19.51%) and rhabdomyolysis (2.44%) occurred in some patients. Multivariate Logistic regression analysis showed that the increase in absolute value of QTc interval ( OR=1.028, 95% CI: 1.000~1.056, P<0.05), lactic acid ( OR=1.599, 95% CI: 1.088~2.350, P<0.05), prothrombin time ( OR=1.205, 95% CI: 1.002~1.450, P<0.05), D-dimer ( OR=1.242, 95% CI: 1.089~1.417, P<0.05), and alkaline phosphatase ( OR=1.013, 95% CI: 1.002~1.024, P<0.05) were the risk factors for the prognosis of patients with colchicine poisoning. The decrease in the absolute value of ADL score ( OR=0.947, 95% CI: 0.909~0.988, P<0.05) and indirect bilirubin ( OR=0.756, 95% CI: 0.572~0.999, P<0.05) were the protective factors for the prognosis of patients with colchicine poisoning. D-dimer (AUC=0.913), lactic acid (AUC= 0.875) and alkaline phosphatase (AUC=0.770) had predictive value for the prognosis of patients with colchicine poisoning, and their cut-off values were 8.965 mg/L, 4.05 mmol/L and 230.5 U/L, respectively. Conclusions:The patients with colchicine poisoning have multiple organ dysfunction on admission, and are in a critical condition. The early levels of D-dimer, lactic acid and alkaline phosphatase could effectively predict the prognosis of patients with colchicine poisoning.
RESUMO
Objective:Early identification of ischemic stroke patients with large vessel occlusion can improve referral efficiency and shorten reperfusion time. The purpose of this study was to analyze the characteristics of patients with large vessel occlusion and identify factors that could predict large vessel occlusion.Methods:The clinical data of 432 patients with ischemic stroke treated through emergency green channel were retrospectively analyzed, and the differences between the large vessel occlusion group (LVO group) and the non-large vessel occlusion group (non-LVO group) were compared, and two independent risk factors of the LVO group were screened out by logistics regression analysis: baseline NIHSS score and D-dimer value. The predicted cutoff values of NIHSS score and D-dimer were further determined by the receiver operating characteristic (ROC) curve.Results:A total of 432 patients with ischemic stroke had complete imaging data, with a mean age of 68.5±12.4 years, including 275 (63.7%) males, and 245 (56.7%) in the LVO group and 187 (43.3%) in the non-LVO group. Age, hemorrhagic transformation, thrombolytic therapy, endovascular treatment, atrial fibrillation, baseline NIHSS score [14.0 (6.0-20.0) vs. 3.0 (1.0-6.0), P<0.05], and D-dimer value at admission [0.9(0.4-2.3) mg/L vs. 0.3 (0.2-0.5)mg/L, P<0.05] were statistically significant different between the two groups. Multivariate Logistic regression analysis showed that higher baseline NIHSS score( OR=1.22,95% CI: 1.17-1.27)and higher D-dimer value( OR=3.10,95% CI: 2.14-4.47)were independent risk factors for large vessel occlusion. Baseline NIHSS score combined with D-dimer value was a good predictor of large vessel occlusion(AUC 0.85 [0.81-0.89]). ROC curve suggested that NIHSS score >6.5 and D-dimer >0.57 mg/L were the cutoff values for predicting large vessel occlusion. Conclusions:Higher baseline NIHSS score and D-dimer value are valuable for early prediction of large vessel occlusion, patients with NIHSS score >6.5 points and D-dimer >0.57 mg/L should be promptly transported to an advanced stroke center for treatment.
RESUMO
Objective:To construct acute ST-segment elevation myocardial infarction (STEMI) percutaneous coronary intervention (PCI) by using lipoprotein-associated phospholipase A2 (Lp-PLA2) and D-dimer to fibrinogen ratio (D/F) and other indicators postoperative patient prognosis nomogram model and evaluation of its predictive value.Methods:A total of 291 acute STEMI patients admitted to the BenQ Hospital Affiliated to Nanjing Medical University from January 2017 to January 2020 were retrospectively selected, including but not limited to Lp-PLA2 and D/F, were collected. Receiver operating characteristic (ROC) curve and multivariate Logistic regression were used to analyze the risk factors of death within 90 d after PCI in STEMI patients, and Kaplan-Meier survival curves were drawn to compare the survival of patients in different Lp-PLA2 and D/F groups. The R language software was used to build nomogram model and decision curve.Results:The AUCs of LpPLA2 and D/F for predicting the risk of death from cardiac causes at 90 s after PCI in patients with acute STEMI were 0.896 (95% CI 0.850 to 0.932) and 0.884 (95% CI 0.837 to 0.922), respectively. The values were 59.50 μg/L and 0.46 respectively ( P<0.05); the mortality rates of acute STEMI patients in LpPLA2>59.50 μg/L and D/F>0.46 groups after PCI were higher than those in LpPLA2≤59.50 μg/L group and D/F≤0.46 group ( P<0.05); age (>66 years), left ventricular ejection fraction (LVEF) (≤45%), LpPLA2 (>59.50 μg/L), D/F (>0.46), N-terminal brain natriuretic peptide precursor (>1.55 μg/L) and fasting blood glucose (>7.00 mmol/L) were the risk of death from cardiac causes at 90 d after PCI in patients with acute STEMI ( P<0.05); when the risk thresholds were >0.24, the nomogram model could provide significant additional net clinical benefit. Conclusions:Lp-PLA2 and D/F are closely related to the prognosis of patients with acute STEMI after PCI, and the nomogram model constructed in combination with other clinical indicators can effectively predict the risk of death within 90 d after PCI.
RESUMO
Objective:To investigate the predictive value of anticardiolipin antibody (ACA) and D-dimer (D-D) combined with risk assessment profile for thromboembolism (RAPT) for deep vein thrombosis (DVT) in elderly postoperative patients with intertrochanteric fracture of femur (IFF).Methods:The clinical data of 123 elderly patients with IFF in Suzhou Hospital Affiliated to Anhui Medical University from January 2019 to March 2022 were retrospectively analyzed. All patients underwent closed reduction intramedullary nail fixation. The patients were divided into DVT group (27 cases) and non-DVT group (96 cases) according to the presence or absence of DVT 7 d after surgery. Before surgery and 3, 5 d after operation, the ACA was detected by enzyme-linked immunosorbent assay, the D-D was detected by automatic coagulation analyzer, and RAPT was performed. The correlation among ACA, D-D and RAPT was analyzed by Spearman method. Multivariate Logistic regression was used to analyze the independent risk factors of DVT in elderly postoperative patients with IFF. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of ACA, D-D and RAPT in predicting DVT in elderly postoperative patients with IFF. The incidences of postoperative DVT in patients with different ACA, D-D and RAPT patients were compared.Results:There were no statistical difference in ACA, D-D and RAPT before operation between the two groups ( P>0.05); the ACA, D-D and RAPT 3 and 5 d after operation in DVT group were significantly higher than those in the non-DVT group, 3 d after operation: (12.44 ± 3.25) × 10 3 RU/L vs. (8.67 ± 2.81) × 10 3 RU/L, (7.29 ± 1.49) mg/L vs. (4.70 ± 1.23) mg/L and (9.79 ± 1.15) scores vs. (9.21 ± 1.32) scores; 5 d after operation: (10.28 ± 2.16) × 10 3 RU/L vs. (6.45 ± 2.04) × 10 3 RU/L, (5.49 ± 1.26) mg/L vs. (3.63 ± 1.05) mg/L and (9.57 ± 1.08) scores vs. (9.12 ± 0.70) scores, and there were statistical differences ( P<0.01 or <0.05). Since ACA, D-D and RAPT in the two groups all reached their peak 3 d after operation, this time point was selected for analysis. Three days after operation, Pearson correlation analysis result showed that ACA and D-D were positively correlated with RAPT ( r = 0.635 and 0.630, P<0.01), and ACA was positively correlated with D-D ( r = 0.657, P<0.01). ROC curve analysis result showed that the area under the curve (AUC) of ACA and D-D combined RAPT 3 d after operation in predicting DVT in elderly postoperative patients with IFF was greater than that predicted by the 3 indexes alone (0.982 vs. 0.894, 0.870 and 0.868), the optimal cut-off values were 11.48 × 10 3 RU/L, 6.75 mg/L and 9 scores. According to the optimal cut-off value of ROC curve analysis at 3 d after operation, the patients were divided into ACA low expression (≤11.48 × 10 3 RU/L, 92 cases) and ACA high expression (>11.48 × 10 3 RU/L, 31 cases), D-D low expression (≤6.75 mg/L, 99 cases) and D-D high expression (>6.75 mg/L, 24 cases), low RAPT (≤9 scores, 93 cases) and high RAPT (>9 scores, 30 cases). The incidences of postoperative DVT in patients with ACA high expression, D-D high expression and high RAPT were significantly higher than those in patients with ACA low expression, D-D low expression and low RAPT: 43.39% (15/31) vs. 13.04% (12/92), 54.17% (13/24) vs. 14.14% (14/99) and 53.33% (16/30) vs. 11.83% (11/93), and there were statistical differences ( χ2 = 16.91, 18.06 and 22.81; P<0.01). After controlling for diabetes and other factors, multivariate Logistic regression analysis result showed that ACA, D-D and RAPT 3 d after operation were independent risk factors for DVT in elderly postoperative patients with IFF ( OR = 2.156, 2.276 and 6.106; 95% CI 1.356 to 3.429, 1.240 to 4.177 and 1.564 to 23.840; P<0.01). Conclusions:The ACA, D-D combined with RAPT can improve the predictive value of DVT in elderly postoperative patients with IFF, which has important reference significance for taking timely and effective intervention measures in early clinical stage.
RESUMO
Objective:To correlate neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and D-dimer (DD) with the severity of acute cholangitis.Methods:The clinical data of 96 patients with acute cholangitis who received treatment in Panjin Central Hospital from September 2019 to March 2021 were retrospectively analyzed. These patients were divided into three groups according to the severity of acute cholangitis: 36 patients with mild acute cholangitis (group A), 35 patients with moderate acute cholangitis (group B), and 25 patients with severe acute cholangitis (group C). The correlation between age, sex, NLR, PLR, DD, and the severity of acute cholangitis was compared among the three groups.Results:In groups A and B, the area under the receiver operating characteristic curve (AUC) showing the performance of DD, NLR, and PLR levels in predicting acute cholangitis was 0.800, 0.838, and 0.721, respectively, with the optimal cut-off value of 1.985 mg/L, 9.589, and 154.410, respectively. Among them, NLR had the largest AUC, and the highest sensitivity (82.9%), and had a high diagnostic value. In groups B and C, the AUC for DD, NLR, and PLR was 0.967, 0.915, and 0.543, respectively, with the optimal cut-off value of 6.000 mg/L, 22.390, and 264.220, respectively. DD and NLR had a diagnostic significance (both P < 0.05), but PLR had no diagnostic significance ( P > 0.05). The AUC for DD was the largest, and therefore DD had a great diagnostic significance. When NLR, PLR, and DD were jointly detected, the AUC was the highest and the diagnostic value was the highest. The AUC in groups A and B was 0.866, and that in groups B and C was 0.977. Conclusion:The levels of DD, NLR, and PLR increase in patients with acute cholangitis, which are related to the severity of the disease. DD, NLR, and PRL can be used as indicators to evaluate mild and moderate acute cholangitis, and NLR has the highest diagnostic value. DD and NLR can be used as indicators to evaluate moderate to severe acute cholangitis, and the effect of DD is superior to that of NLR. The combined detection of the three indicators can increase the value to evaluate the severity of acute cholangitis, and its effect is superior to that of a single detection. The combined detection of NLR, PLR, and DD is helpful for the clinical diagnosis and treatment of acute cholangitis.
RESUMO
Objective:To analyze the effects of the primary location of colorectal cancer on the surgical outcome of liver metastases.Methods:A cross-sectional study was conducted on 178 patients with liver metastases from colorectal cancer admitted to Binzhou Central Hospital from January 2012 to January 2022. According to whether the patients had recurrence after surgery, they were divided into a recurrence group ( n = 88) and a control group ( n = 90). The general and clinical data were compared between the two groups. Logistic multivariate analysis of the factors with statistical significance was further performed to identify the risk factors of postoperative recurrence of liver metastases from colorectal cancer after surgery. The correlation between the primary location of colorectal cancer and each risk factor was analyzed. The recurrence of colorectal cancer was compared anong patients with different primary locations of colorectal cancer at 12 months after surgery. Results:Primary location at the right colon [55.68% (49/88), lymph node metastasis [92.05% (81/88)], D-dimer ≥ 180 μ g/L, albumin < 29 g/L, ineffective/no neoadjuvant chemotherapy [43.18% (33/38)], and high-risk clinical risk score [53.41% (47/88)] were risk factors for postoperative recurrence of liver metastases from colorectal cancer after surgery ( P = 0.024, 0.019, 0.001, 0.028, < 0.001, 0.001). The primary location of colorectal cancer was positively correlated with lymph node metastasis, D-dimer, and clinical risk score ( P = 0.043, 0.046, 0.030), and negatively correlated with albumin and the efficacy of neoadjuvant chemotherapy ( P = 0.004, 0.033). In 178 patients, the recurrence rate of liver metastases from colorectal cancer at 3 months [53.57% (15/70)], 6 months [55.17% (32/70)], and 12 months [55.68% (49/70)] was significantly higher in the right colon compared with the left colon [32.14% (9/40), 24.14% (14/40), 26.14% (23/40) and the rectum [14.29% (4/68), 20.69% (12/68), 18.18% (16/68)] ( χ2= 4.73, 7.85, 6.27, all P < 0.05). Conclusion:Right colon, lymph node metastasis, D-dimer, albumin, neoadjuvant chemotherapy efficacy, and clinical risk score are the risk factors for postoperative recurrence of liver metastases from colorectal cancer. Patients with the primary location at the right colon have a higher postoperative recurrence rate.
RESUMO
Objective:To investigate the change of D-Dimer (D-D), cardiac troponin I (cTnI) and vasoactive-inotropic score (VIS) after Stanford type A aortic dissection (TAAD) and thier predictive effect on death outcome.Methods:120 patients with TAAD who were treated in the Affiliated Hospital of Jining Medical College from January 2019 to January 2022 were retrospectively selected and divided into death group ( n=17) and survival group ( n=103) according to the 28-day survival after operation. The difference of clinical data between the two groups was compared, and the influencing factors of postoperative death in TAAD patients were analyzed by logistic regression method. Results:The age, deep hypothermic circulatory arrest time, D-D and cTnI of the patients in the death group were (60.50±5.42)years old, (30.40±9.92)min, (15.65±5.52)g/L and (3.32±0.82)mg/L, respectively, which were significantly higher than those in the survival group (all P<0.05). The VIS score and change of VIS score in the death group at 24 hours after operation were (9.66±1.10)points and (4.50±0.91)points respectively, which were significantly higher than those in the survival group (all P<0.05). Logistic regression analysis showed that age, D-D, cTnI and change of VIS score were the influencing factors of death after TAAD (all P<0.05). The area under the receiver operating characteristic (ROC) curve predicted by the D-D, cTnI and change of VIS score for death in TAAD patients was 0.718, 0.691 and 0.789 respectively (all P<0.05). Conclusions:Postoperative death of TAAD patients is affected by their age, D-D, cTnI and change of VIS score. The D-D, cTnI and change of VIS score have certain application value in predicting postoperative death of patients.
RESUMO
Objective:To investigate the relationship between change of serum D-dimer (D-D), soluble vascular cell adhesion molecule 1 (sVCAM-1), P-selectin and thrombosis after limb fracture surgery.Methods:289 patients with limb fractures who were treated in the emergency department of Shulan (Hangzhou) Hospital from January 2021 to January 2022 were selected as the study subjects. They were divided into deep vein thrombosis (DVT) group ( n=62) and non-DVT group ( n=227) according to whether DVT occurred after operation. The levels of prothrombin time (PT), activated partial prothrombin time (APTT), D-D, sVCAM-1 and P-selectin were measured before and after operation in all patients. The levels of PT, APTT, D-D, sVCAM-1 and P-selectin were compared between DVT group and non-DVT group. Logistic sequential stepwise regression analysis was used to analyze the risk factors of postoperative thrombosis in patients with limb fractures. Results:There was no statistically significant difference in PT and APTT between 289 patients with limb fractures after operation and before operation (all P>0.05), while the levels of serum D-D, sVCAM-1 and P-selectin after operation were higher than that before operation (all P<0.05). There was no significant difference in general data between DVT group and non-DVT group (all P>0.05); There was no statistically significant difference in PT and APTT before and after operation between DVT group and non-DVT group (all P>0.05). The levels of serum D-D, sVCAM-1 and P-selectin before and after operation in DVT group were higher than those in non-DVT group (all P<0.05). Logistic sequential stepwise regression analysis showed that high levels of D-D, sVCAM-1 and P-selectin were risk factors for thrombosis after limb fracture surgery (all P<0.05). Conclusions:High levels of D-D, sVCAM-1 and P-selectin are risk factors for thrombosis after limb fracture surgery.
