RESUMEN
BACKGROUND: Fondaparinux sodium can prevent and treat acute illnesses and venous thromboembolism in patients undergoing surgery. At present, no studies have reported on treating subchorionic hematoma combined with protein S deficiency using fondaparinux sodium. OBJECTIVE: To investigate the clinical efficacy of fondaparinux sodium in the treatment of patients with subchorionic hematoma combined with protein S deficiency. METHODS: This single-center, open-ended, and prospective study enrolled 78 patients with subchorionic hematoma and protein S deficiency. They were randomly assigned to the treatment and control groups. The control group received conventional treatment, and the observation group received subepithelial injections of fondaparinux sodium (2.5 mg/day) based on conventional treatment. After 30 days of continuous treatment, the hematoma was evaluated by ultrasonography. RESULTS: After treatment with fondaparinux sodium, a significant improvement in subchorionic hematoma was observed in the observation group compared with that in the control group (p< 0.05). A substantial improvement in prothrombin time and activated partial thromboplastin time was observed in the observation group after fondaparinux sodium treatment (p< 0.05). Furthermore, after fondaparinux sodium treatment, the duration of hematoma maintenance and incidence of adverse pregnancy outcomes were significantly reduced in the observation group compared with that in the control group (p< 0.05). CONCLUSION: With a favorable safety profile, fondaparinux sodium is effective in treating subchorionic hematoma combined with protein S deficiency. The results provide new ideas and methods for treating this disease, which is worthy of further promotion and application in clinical practice.
RESUMEN
Introduction: Screening and postoperative intervention of breast tumors are critical for the effective diagnosis and treatment of disease development, and reliable diagnostic/screening methods become a key link. Objective: Thromboelastogram (TEG), routine platelet (PLT) count, and the coagulation function indicators in patients with different breast diseases were determined and analyzed to explore their predictive value in secondary bleeding disorders. Methods: A total of 131 patients with breast diseases, admitted to Jiangsu University Affiliated Hospital from January 2019 to December 2022, were selected as the research subjects. The detection items were analyzed using the receiver operating curve (ROC) after grouping for secondary bleeding disorders of patients with breast cancer. Results: The reaction (R) and the coagulation (K) times were lower in the malignant breast disease group, while the coagulation angle (α), maximum amplitude (MA), coagulation index (CI), fibrinogen (FIB), and D-dimer (D-D) were higher than those in the benign breast disease group. The t-tests proved that the MA and FIB values were statistically significant (p < 0.05) in the benign and malignant breast disease groups. The R and K in patients with breast diseases were positively correlated with the activated partial thromboplastin time (aPTT) and D-D, but were negatively correlated with PLT. The α angle was negatively correlated with aPTT and D-D, but was positively correlated with PLT. The MA for PLT function was positively correlated with FIB and PLT. CI was negatively correlated with aPTT, thrombin time (TT), and D-D, but was positively correlated with PLT. ROC curve analysis showed that the CI and α angle had a significant predictive value, whereas the correlation of the other indicators was relatively low. Conclusion: Coagulation tests showed significant differences in patients with breast cancer, differing from those with benign breast diseases. TEG combined with conventional coagulation indicators is potentially valuable for the prediction of secondary bleeding disorders in patients with breast cancer.
RESUMEN
BACKGROUND: Perioperative heparin-free anticoagulation extracorporeal membrane oxygenation (ECMO) for lung transplantation is rarely reported. OBJECTIVE: To evaluate the impact of a heparin-free strategy on bleeding and thrombotic events, blood transfusion, and coagulation function during the early perioperative period and on prognosis, and to observe its effect on different ECMO types. DESIGN: A retrospective cohort study. METHODS: Data were collected from 324 lung transplantation patients undergoing early perioperative heparin-free ECMO between August 2017 and July 2022. Clinical data including perioperative bleeding and thrombotic events, blood product transfusion, coagulation indicators and 1-year survival were analysed. RESULTS: Patients were divided in venovenous (VV; n = 251), venoarterial (VA; n = 40) and venovenous-arterial (VV-A; n = 33) groups. The VV group had the lowest intraoperative bleeding and thoracic drainage within 24 h postoperatively. Vein thrombosis occurred in 30.2% of patients within 10 days postoperatively or 1 week after ECMO withdrawal, and no significant difference was found among the three groups. Double lung transplantation, increased intraoperative bleeding, and increased postoperative drainage were associated with vein thrombosis. Except for acute myocardial infarction in one patient, no other serious thrombotic events occurred. The VV-ECMO group had the lowest demand for blood transfusion. The highest prothrombin time and the lowest fibrinogen levels were observed in the VA group during ECMO run, while the highest platelet counts were found in the VV group. Both intraoperative bleeding and thoracic drainage within 24 h postoperatively were independent predictors for 1-year survival, and no thrombosis-related deaths occurred. CONCLUSION: Short-term heparin-free anticoagulation, particularly VV-ECMO, did not result in serious thrombotic events or thrombosis-related deaths, indicating that it is a safe and feasible strategy for perioperative ECMO in lung transplantation.

Air pollution exposure has been linked with coagulation function. However, evidence is limited for the relationships between air pollution, coagulation function and metabolomics in humans. We recruited a panel of 130 rural elderly from the Chayashan township in China, all of whom were free of pre-existing cardiovascular diseases and had provided residential address information. We conducted clinical examinations and collected blood samples from these rural elderly for the detection of coagulation biomarkers (e.g, activated partial thromboplastin time, fibrinogen, thrombin time, and prothrombin time) and untargeted metabolites in both December 2021 and August 2022. We used mini ambient air quality monitor to measure the mean levels of five air pollutants (e.g., PM2.5, SO2, NO2, CO and O3) during 1 to 2 weeks before blood sample collection. The Mummichog pathway analysis was used to identified potential metabolic features and pathways. In this study, we identified 5 pathways associated with both air pollution and coagulation function, and further pinpointed eight metabolic features within these pathways. The majority of these features were lipids, including arachidonic acid and linoleic acid. Overall, the findings of this study offer insights into potential mechanisms, particularly lipid metabolism, that may underlie the association between air pollution and coagulation function.
RESUMEN
Preeclampsia (PE) is a severe pregnancy complication characterized by significant alterations in coagulation function. This study aims to analyze the correlation between coagulation function, platelet parameters, and pregnancy outcomes in PE patients. Clinical data, along with blood and urine samples, were collected from 168 PE patients and 128 healthy pregnant women. General demographic and laboratory testing data were recorded, and maternal and fetal outcomes were followed up. Data were analyzed using Kaplan-Meier and logistic regression analyses. In mild PE patients, thrombin time (p = .000), platelet distribution width (PDW) (p = .000), and clot formation time (p = .000) were increased, while prothrombin time (p = .000) and fibrinogen (p = .045) were reduced. With increasing PE severity, prothrombin time (p = .000), platelet count (PLT) (p = .000), mean platelet volume (MPV) (p = .000), plateletcrit (p = .000), maximum amplitude (MA) (p = .000), and coagulation index (p = .001) decreased, whereas activated partial thromboplastin time (APTT) (p = .000), thrombin time (p = .002), D-dimer (p = .026), and PDW (p = .000) increased. Lower prothrombin time (p = .048), PLT (p = .004), and coagulation index (p = .026) or higher APTT (p = .032), thrombin time (p = .044), D-dimer (p = .023), and PDW (p = .016) were associated with a higher risk of poor pregnancy outcomes. Thrombin time was identified as an independent risk factor (p = .025, OR = 2.918, 95% CI: 1.145-7.436), whereas gestational age was an independent protective factor (p = .000, OR = 0.244, 95% CI: 0.151-0.395). This study demonstrates that specific coagulation and platelet parameters are significantly associated with PE severity and adverse pregnancy outcomes. These findings highlight the importance of monitoring coagulation function in PE patients to improve clinical management and outcomes.
RESUMEN
PURPOSE: Our previous research has revealed that mild hypothermia leads to excessive bleeding in thoracic surgeries, while the underlying mechanism stayed unrevealed by the standard coagulation tests. The research question in this study was as follows: "How does mild hypothermia impair the hemostatic function in patients receiving thoracic surgeries?". The purpose was to detect the disturbed coagulation processes by comparing the TEG parameters in patients receiving active vs. passive warming during thoracic surgeries. METHODS: Standard coagulation tests and thromboelastography (TEG) were adopted to compare the hemostatic functions in patients receiving active vs. passive warming during thoracic surgeries. Furthermore, blood samples from passive warming group were retested for TEG at actual core body temperatures. RESULTS: Sixty-four eligible patients were included in this study. TEG revealed that mild hypothermia significantly disturbed coagulation by decreasing MA (59.4 ± 4.5 mm vs. 64.2 ± 5.7 mm, p = 0.04) and α angle (70.4 ± 5.2° vs. 74.9 ± 4.4°, p = 0.05) and prolonging ACT (122.2 ± 19.3 s vs. 117.3 ± 15.2 s, p = 0.01) and K time (1.9 ± 1.0 s vs. 1.3 ± 0.4 min, p = 0.02). TEGs conducted under core body temperatures revealed more impaired coagulation than those incubated at 37 °C. Furthermore, postoperative shivering and waking time were significantly increased in mild hypothermic patients. CONCLUSION: Mild hypothermia significantly impaired coagulation function in patients receiving thoracic surgeries, which could be detected by TEGs other than the standard coagulation tests. Temperature-adjusted TEGs may provide a preferable method of hemostatic monitoring and transfusion guidance in thoracic surgeries, which warrants further clinical investigations.
RESUMEN
OBJECTIVE: To examine the impact of using intraoperative cell salvage (ICS) for the restoration of coagulation function in cases of massive Post-Cesarean Section Hemorrhage (PCSH). METHODS: A retrospective analysis was conducted on 60 cases of massive PCSH meeting inclusion criteria at Suqian Maternity and Children's Hospital from January 2020 to July 2022. Patients were divided into two groups: allogeneic blood transfusion group (Group A, n = 30) and ICS group (Group B, n = 30), based on transfusion methods. Blood parameters, coagulation function, and adverse reactions were assessed before (T0) and after (T1) transfusion. Patients were categorized into good prognosis (GP) and poor prognosis (PP) groups based on adverse reaction occurrence. Clinical profiles were compared between groups, and multivariate binary logistic regression analysis was employed to evaluate the factors that may affect the prognosis in women with PCSH. RESULTS: No significant differences in routine blood parameters were observed between groups at T0 and T1 (P>0.05). At T0, no significant differences in PT, APTT, TT, or FIB were found between groups (P>0.05). Both groups showed a reduction in PT, APTT, and TT values at T1 compared to T0, with Group B experiencing a more significant decrease than Group A (P<0.05). FIB increased in both groups at T1 compared to T0, with Group B demonstrating a higher increase than Group A (P<0.05). Both groups showed increased blood pressure at T1 compared to T0, with Group B showing a more pronounced elevation than Group A (P<0.05). The occurrence of adverse reactions was significantly lower in Group B (1/30, 3.33%) compared to Group A (7/30, 23.33%) (P<0.05). Logistic regression analysis identified FIB<1.52 g/L and HR<45.35 times/min as factors associated with increased risk of unfavorable outcome in women with PCSH. CONCLUSION: In patients experiencing significant PCSH, ICS may lead to better postoperative recovery of blood parameters, faster restoration of coagulation function, and reduced risk of adverse events compared to ABT. Moreover, early detection of coagulation function and blood gas indexes is crucial for clinicians to implement timely prevention and treatment measures.
RESUMEN
BACKGROUND: Intramural hematoma of the small bowel is a rare yet acute gastrointestinal condition typically linked with impaired coagulation function, often posing diagnostic challenges. It is principally encountered in patients undergoing prolonged anticoagulant therapy, specifically warfarin. CASE PRESENTATION: We reported a case of intramural hematoma associated with warfarin use. The patient was admitted to hospital with abdominal pain and had received anticoagulant therapy with warfarin 2.5 mg/day for 4 years. Laboratory examination showed decreased coagulation function, abdominal CT showed obvious thickening and swelling of part of the jejunal wall, and abdominal puncture found no gastroenteric fluid or purulent fluid. We treated the patient with vitamin K and fresh frozen plasma. The patient was discharged after the recovery of coagulation function. Then we undertaook a comprehensive review of relevant case reports to extract shared clinical features and effective therapeutic strategies. CONCLUSION: Our analysis highlights that hematoma in the small intestinal wall caused by warfarin overdose often presents as sudden and intense abdominal pain, laboratory tests suggest reduced coagulation capacity, and imaging often shows thickening of the intestinal wall. Intravenous vitamin K and plasma supplementation are effective non-surgical strategies. Nevertheless, in instances of severe obstruction and unresponsive hemostasis, surgical resection of necrotic intestinal segments may be necessary. In the cases we reported, we avoided surgery by closely monitoring the coagulation function. Therefore, we suggest that identifying and correcting the impaired coagulation status of patient is essential for timely and appropriate treatment.

BACKGROUND: To evaluate the association of coagulation disorder score with the risk of in-hospital mortality in acute respiratory distress syndrome (ARDS) patients. METHODS: In this cohort study, 7,001 adult patients with ARDS were identified from the Medical Information Mart for Intensive Care Database-IV (MIMIC-IV). Univariate and multivariate Logistic stepwise regression models were used to explore the associations of coagulation-associated biomarkers with the risk of in-hospital mortality in patients with ADRS. Restricted cubic spline (RCS) was plotted to explore the association between coagulation disorder score and in-hospital mortality of ARDS patients. RESULTS: The follow-up time for in-hospital death was 7.15 (4.62, 13.88) days. There were 1,187 patients died and 5,814 people survived in hospital. After adjusting for confounding factors, increased risk of in-hospital mortality in ARDS patients was observed in those with median coagulation disorder score [odds ratio (OR) = 1.22, 95% confidence interval (CI): 1.01-1.47) and high coagulation disorder score (OR = 1.38, 95% CI: 1.06-1.80). The results of RCS indicated that when the coagulation disorder score >2, the trend of in-hospital mortality rose gradually, and OR was >1. CONCLUSIONS: Poor coagulation function was associated with increased risk of in-hospital mortality in ARDS patients. The findings implied that clinicians should regularly detect the levels of coagulation-associated biomarkers for the management of ARDS patients.

Introduction: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel bunyavirus infection with a high lethality rate. The purpose of this study was to investigate the changes in coagulation parameters in patients with SFTS, aiming to provide clinical evidence for early diagnosis, treatment, and disease analysis. Methods: A total of 40 patients with SFTS attended from April 1, 2020 to May 21, 2022 in Nanjing Drum Tower Hospital were selected and grouped according to the duration of the disease, mild and severe disease, cure and death, with 50 healthy physical examiners as controls, and the risk of severe and death disease was predicted using ROC curves. Results: Comparison between the healthy, mild and severe groups revealed that PT, INR, APTT, TT, D-D and vWF levels were higher than those in the healthy control group, and FII, FIX, FX, FXI, FXII, PC and PS levels were lower than those in the healthy control group, the differences were statistically significant (p < 0.05). Comparing the results of SFTS patients with different course times, the results of Fib, FV, FVII, FVIII, FIX, FX, FXI were statistically significant (p < 0.05). Among the survived and deceased patients, the PT, INR, DD and PS results of the deceased patients were higher than those of the survived patients, and the FVIII, FIX, FXI, FXII and PC were lower than those of the survived patients. The area under the ROC curve showed that D-D had higher predictive ability for the risk of severe disease (AUROC 0.93, sensitivity and specificity at a Cut-off value of 1.50 mg/L were 90.0 and 86.5%, respectively) and the risk of death occurring (AUROC 0.84, sensitivity and specificity at a Cut-off value of 3.39 mg/L were 87.5 and 80.0%, respectively). Discussion: The monitoring of the coagulation parameters in patients with SFTS is great significance for identifying the severity and death of the patient's condition, and it is of great clinical value to provide early attention, timely intervention and maximum reduction of the mortality rate for patients at risk of severe disease.
RESUMEN
OBJECTIVE: To evaluate the effects of argatroban on the levels of Hcy, hs-CRP and FIB in patients with acute cerebral infarction (ACI). METHODS: A retrospective analysis was performed on 382 patients with ACI who were hospitalized in the Department of Neurology of our hospital from January 2017 to December 2019. Among them, 158 patients received conventional treatment as the control group and 224 patients received combined treatment with argatroban as the study group. NHISS score, mRS score, Hcy, hs-CRP, FIB level, quality of life, adverse reactions were compared between the two groups after treatment. The levels of Hcy and hs-CRP in patients with different mRS scores were compared. RESULTS: A superior clinical efficacy of the study group was observed than the control group (p < 0.05). The study group witnessed a remarkably lower NHISS score, Hcy, hs-CRP and FIB level as compare to the control group (p < 0.05). The ADL and FMA scores in the study group were higher than those in the control group (p < 0.05). The levels of Hcy and hs-CRP in mRS 0-2 patients were lower than those in mRS 3-6 patients (p < 0.05). CONCLUSION: Argatroban in ACI patients can significantly enhance the clinical efficacy and improve the quality of life. It is closely related to the reduction of Hcy and hs-CRP levels, but the mechanism needs to be further studied.
RESUMEN
OBJECTIVE: To analyze the predictive value of coagulation function, alpha-fetoprotein (AFP) and placental growth factor (PIGF) for postpartum hemorrhage in patients with perilous placenta previa (PPP). METHODS: The clinical data of 104 PPP patients were retrospectively analyzed. The patients were divided into a hemorrhage group (n=68) and a non-hemorrhage group (n=36). A total of 55 healthy pregnant women were recruited as controls. The coagulation function, AFP and PIGF were compared between the three groups. Multivariate logistic regression was performed to determine independent risk factors for hemorrhage. RESULTS: PT, TT, APTT, FIB and AFP were significantly higher while PIGF was lower in the PPP group than the control group (all P<0.05). Placental adhesion (OR 3.924, 95% CI 1.389-11.083, P=0.01), anterior placenta (OR 4.583, 95% CI 1.589-13.22, P=0.005), AFP (OR 0.208, 95% CI 0.068-0.635, P=0.006) and PIGF (OR 3.963, 95% CI 1.385-11.34, P=0.01) were independent risk factors for hemorrhage. CONCLUSION: Coagulation function, AFP and PIGF could predict postpartum hemorrhage in PPP patients.
RESUMEN
OBJECTIVE: To analyze the effects of Butylphthalide on cerebral vascular circulation, coagulation function, and neurological function in patients with acute severe ischemic stroke following intravenous thrombolysis. METHODS: Clinical efficacy, cerebral vascular circulation indicators [anterior cerebral artery (ACA), middle cerebral artery (MCA), vertebral artery (VA) blood flow velocity], coagulation function indicators [prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (FIB)], neurological function indicators [Activities of Daily Living (ADL) score. RESULTS: The total effective rate of treatment in the control group was 76.47%, while in the observation group, it was 96.08%, with the observation group showing a significantly higher total effective rate than the control group (p < 0.05). Before treatment, there was no significant difference in ACA, MCA, and VA blood flow velocity between the two groups (p > 0.05). However, after treatment, the ACA, MCA, and VA blood flow velocity in the observation group were significantly higher than those in the control group (p < 0.05). Before treatment, there was no significant difference in PT, APTT, TT, and FIB levels between the two groups (p > 0.05). CONCLUSION: In patients with acute severe ischemic stroke undergoing intravenous thrombolysis, the addition of Butylphthalide to the treatment regimen yields favorable clinical outcomes. Compared to Alteplase alone, the addition of Butylphthalide further improves cerebral vascular circulation and coagulation function, promoting the recovery and reconstruction of neurological function in patients. Importantly, the addition of Butylphthalide does not increase the risk of adverse reactions, making it a safe and ideal option for clinical application.
RESUMEN
This retrospective study analyzed the efficacy of combined antiplatelet therapy with Argatroban in treating acute ischemic stroke (AIS) and its impact on patients' coagulation and neurological functions. Clinical data of 113 AIS patients admitted between January 2021 and January 2023 were retrospectively analyzed. Patients were divided into control (n = 56) and observation (n = 57) groups based on treatment interventions. The control group patients were treated with antiplatelet drugs, while the observation group patients received combination therapy with apatinib on the basis of the control group treatment. Compared to the control group, the observation group demonstrated higher clinical efficacy, improved coagulation parameters, reduced stroke severity (measured by NIHSS), enhanced daily living abilities (BI scores), and lowered inflammatory and neural injury markers post-treatment. Adverse reaction incidence was similar between groups. Combining Argatroban with antiplatelet drugs in AIS management showed superior efficacy without increasing adverse effects, suggesting its potential for clinical application.
RESUMEN
Hemostatic disturbances after cardiac surgery can lead to excessive postoperative bleeding. Thromboelastography (TEG) was employed to evaluate perioperative coagulative alterations in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB), investigating the correlation between factors concomitant with cardiac surgery and modifications in coagulation. Coagulation index as determined by TEG correlated significantly with postoperative bleeding at 24-72â h after cardiac surgery (P < .001). Among patients with a normal preoperative coagulation index, those with postoperative hypocoagulability showed significantly lower nadir temperature (P = .003), larger infused fluid volume (P = .003), and longer CPB duration (P = .033) than those with normal coagulation index. Multivariate logistic regression showed that nadir intraoperative temperature was an independent predictor of postoperative hypocoagulability (adjusted OR: 0.772, 95% CI: 0.624-0.954, P = .017). Multivariate linear regression demonstrated linear associations of nadir intraoperative temperature (P = .017) and infused fluid volume (P = .005) with change in coagulation index as a result of cardiac surgery. Patients are susceptible to hypocoagulability after cardiac surgery, which can lead to increased postoperative bleeding. Ensuring appropriate temperature and fluid volume during cardiac surgery involving CPB may reduce risk of postoperative hypocoagulability and bleeding.

Objective: In this study, we evaluated the efficacy of tranexamic acid (TXA) and acute normovolemic hemodilution (ANH) with 6% hydroxyethyl starch (130/0.4) in minimizing blood loss during open partial liver resection. Coagulation function was assessed using thromboelastography (TEG) and hemostasis tests, while renal function changes were tracked through serum creatinine values post-surgery. Methods: Thirty patients undergoing open partial liver resection were allocated to two groups: Group T received TXA + ANH, and Group A received ANH alone. Blood was drawn from the radial artery under general anesthesia. Both groups received peripheral vein injections of 6% hydroxyethyl starch 130/0.4. Group T additionally received intravenous TXA. Primary outcomes included blood loss and allogeneic blood transfusions. TEG assessed coagulation status and renal function was monitored. Results: Group T demonstrated superior outcomes compared to Group A. Group T had significantly lower intraoperative blood loss (700 mL vs 1200 mL) and a lower bleeding rate per kilogram of body weight (13.3 mL/kg vs 20.4 mL/kg). Coagulation parameters favored Group T, with higher TEG maximum amplitude (55.91 mm vs 45.88 mm) and lower activated partial thromboplastin time (38.04 seconds vs 41.49 seconds). Neither group experienced acute renal injury or kidney function deficiency during hospitalization. Conclusion: TXA and ANH in a small dose during liver resection stabilize clotting, reduce blood loss by 6% compared to hydroxyethyl starch 130/0.4, and do not affect renal function.
RESUMEN
OBJECTIVE: Hematological consequences of novel antiseizure medications (ASMs) or combined therapies are rarely reported, especially in pediatric patients undergoing surgery for epilepsy. This study aimed to assess the prevalence and risk factors of coagulation dysfunction in this population and evaluate their relationship with intra- and postoperative bleeding. METHODS: Three hundred ninety children who underwent surgery for epilepsy and 104 children without epilepsy who underwent nonepilepsy surgery at the authors' center were included in the study. The authors retrospectively collected and analyzed the following clinical data: sex, age, weight, course of epilepsy, antiseizure therapy, first laboratory data after admission, and transfusion-related data. RESULTS: ASMs were responsible for the higher incidence of coagulation dysfunction in pediatric epilepsy surgery patients. Low body weight (OR 0.95, 95% CI 0.92-0.98) and valproic acid (VPA) therapy (OR 5.13, 95% CI 3.25-8.22) were the most relevant factors leading to coagulation dysfunction. The most common hematological side effects of VPA were thrombocytopenia and hypofibrinogenemia, whereas low body weight was only associated with hypofibrinogenemia. Both VPA and low body weight increased the need for intra- or postoperative transfusion (p < 0.001). CONCLUSIONS: Pediatric epilepsy surgery patients often take multiple ASMs, resulting in an increased incidence of coagulopathy. VPA levels and low body weight were found to be the main influential factors associated with an increased risk of coagulation dysfunction. Platelet and fibrinogen levels were the main indices that were affected. Both VPA and low body weight were relevant to additional surgery-related transfusion, necessitating the need for increased awareness of preoperative coagulopathy before pediatric epilepsy surgery. Clinical trial registration no.: NCT05675254 (ClinicalTrials.gov).

BACKGROUND: Endometrial cancer is currently the prevalent malignant cancer worldwide. Diagnostic efficiency of tumor markers is limited, and coagulation function indicators in endometrial cancer are less concerned. METHODS: This study attempted to evaluate the effects of coagulation function indicators and tumor markers on the clinical diagnosis and clinicopathological characteristics of patients with endometrial cancer. The retrospective analysis compared the differences in coagulation function indicators and tumor markers among 175 patients with endometrial cancer and 170 healthy women from January 2020 to October 2022. RESULTS: Compared to the healthy control, the levels of D-dimer, fibrinogen, human epididymis protein 4 (HE4), carbohydrate antigen 125 (CA125), CA153, and CA199 in patients with endometrial cancer were significantly higher (P < 0.05). Univariate and multivariate regression analyses revealed that abnormal levels of D-dimer, fibrinogen, HE4, CA125, CA153, and CA199 were related risk factors affecting the incidence of endometrial cancer. Receiver operating characteristic curve analysis exhibited that the area under the curve (0.931) and accuracy (85.2%) of combined diagnosis of coagulation function indicators (D-dimer, fibrinogen) and tumor markers (HE4, CA125, CA153, CA199) were the highest, and its sensitivity (82.3%) and specificity (88.2%) were higher than any single or combined indicators of four tumor markers. Moreover, relative expression levels of the combined indicators were significantly different among clinicopathological characteristics that had the highest predictive value in the FIGO stage (P < 0.001). CONCLUSIONS: D-dimer and fibrinogen represent potential diagnostic factors for endometrial cancer. The combination of coagulation function indicators and tumor markers exhibited high diagnostic value in endometrial cancer, as well as predictive value for clinicopathological characteristics.

Background: This study aims to explore the factors influencing the coagulation function of patients with chronic obstructive pulmonary disease (COPD) and its effects on thrombosis. Methods: A total of 155 COPD patients, including 118 patients with acute exacerbation of COPD (AECOPD) and 37 patients with stable COPD (SCOPD), were enrolled in this study. Meanwhile, 50 patients with gastrointestinal polyps found during physical examination and treated with surgery in the same period were enrolled as the control group. The basic data, routine blood tests, C-reactive protein (CRP), procalcitonin (PCT), and coagulation indexes of the three groups were collected, as well as arterial blood gas indexes of AECOPD patients. Results: The differences in erythrocyte count and hemoglobin among groups were not statistically significant. Compared with the SCOPD group and control group, white blood cell (WBC), neutrophil percentage, PCT, CRP, prothrombin time (PT), and fibrinogen (FIB) in the AECOPD group increased significantly, while the international normalized ratio (INR) decreased (P < 0.05). The differences in activated partial thromboplastin time (APTT) and D-dimer among groups were not statistically significant (P > 0.05). Thrombin time (TT) in the AECOPD group was shorter than that of the control group, and PT was longer than that of the SCOPD group (P < 0.05). Five patients with AECOPD and one patient with SCOPD had venous thrombosis. Conclusion: The abnormal coagulation function in AECOPD patients is related to the degree of infection and hypercapnia, which may be a risk factor for thrombosis.
RESUMEN
Reports of rare but severe thrombotic events after receiving some COVID-19 vaccines brought concerns for the possibility of vaccine-induced coagulation abnormality. However, no study has reported the impacts of COVID-19 vaccination on coagulation function in pregnant women. We aimed to explore whether vaccination with inactivated COVID-19 vaccines before pregnancy was associated with coagulation changes in pregnant women. We conducted a retrospective cohort study in a tertiary-care hospital in Shanghai, China. A total of 5166 pregnant women were included, of whom 2721 (52.7%) completed vaccination before conception. Compared with unvaccinated women, the mean serum levels of prothrombin time (PT) and fibrinogen (FIB) were lower in vaccinated women by 0.09 (ß = -0.09, 95% confidence interval [CI], -0.13, -0.05) mg/L and 0.11 (ß = -0.11, 95% CI, -0.15, -0.07) mg/L, and the mean D-Dimer (D-D) levels were higher by 0.12 (ß = 0.12, 95% CI, 0.09, 0.15) mg/L. However, no significant association was observed between COVID-19 vaccination and serum levels of activated partial thromboplastin time (APTT), fibrinogen degradation product (FDP) or thrombin time (TT). Our findings suggested that inactivated COVID-19 vaccination before conception resulted in a small change in maternal coagulation function, but this might not have clinical significance.
