ABSTRACT
Objetivo: Evaluar el valor predictivo negativo de la ratio antigénica y conocer su rentabilidad para descartar preeclampsia precoz en pacientes de alto riesgo de desarrollarla, con profilaxis de ácido acetilsalicílico. Métodos: Se realizó un estudio descriptivo transversal que recogió a las gestantes con cribado de preeclampsia precoz de alto riesgo (384 gestantes) en el Hospital Santa Lucía durante el año 2021, para lo que se usó test Elecsys® tabulado a un riesgo mayor a 1/150 en primer trimestre, y que tomaran ácido acetilsalicílico antes de la semana 16, quedando en 368 gestantes vistas en las semanas 20, 26, 31 y 36. Se realizó biometría, ratio angiogénica y doppler. Resultados: La incidencia de preeclampsia precoz en la población fue 4 casos (incidencia 1,08 %). Son significativos por su alto valor predictivo negativo del 100 % de preeclampsia precoz: la ratio angiogénica mayor a 38 en la semana 26 y el doppler de las uterinas en semana 20 y 26. Conclusión: En gestaciones con cribado de alto riesgo de preeclampsia que tomen ácido acetilsalicílico, una ratio angiogénica menor a 38 en la semana 26, además de un doppler uterino normal en semana 20 y 26 permite reducir el seguimiento gestacional(AU)

Resumo Fundamento Fibrilação atrial nova (FAN) ocorre em pacientes internados por COVID-19. Há controvérsias quanto ao valor preditivo de dados clínicos e laboratoriais à admissão hospitalar para ocorrência de FAN. Objetivos Analisar, à admissão hospitalar, variáveis com potencial preditivo para ocorrência de FAN em pacientes com pneumonia por COVID-19. Método Estudo observacional, retrospectivo, caso-controle. Foram avaliados prontuários eletrônicos de pacientes consecutivos ≥ 60 anos, hospitalizados com pneumonia por COVID-19 entre 1º de março e 15 de julho de 2020. Comparações feitas pelos testes `t' de Student ou qui-quadrado. Foi empregado modelo de risco proporcional de Cox para identificação de preditores de FAN. Considerou-se o valor de p < 0,05 como estatisticamente significativo. Resultados Entre 667 pacientes internados por COVID-19, 201 (30,1%) foram incluídos. FAN foi documentada em 29 pacientes (14,4%) (grupo 1). Grupo 2 foi composto por 162 pacientes que não apresentaram FAN. Dez pacientes excluídos por estarem em FA na admissão hospitalar. Houve diferenças entre os grupos 1 e 2, respectivamente, no tempo de permanência em UTI (11,1±10,5 dias vs. 4,9±7,5 dias; p=0,004), necessidade de ventilação invasiva (82,9% e 32,7%; p<0,001) e mortalidade hospitalar (75,9% vs. 32,1%; p<0,001). No modelo de Cox, idade > 71 anos (hazard ratio [HR]=6,8; p<0,001), leucometria ≤ 7.720 cels.μL-1 (HR=6,6; p<0,001), natremia ≤ 137 mEq.L-1 (HR=5,0; p=0,001), escore SAPS3 > 55 (HR=5,6; p=0,002) e desorientação (HR=2,5; p=0,04) foram preditores independentes de FAN. Conclusões FAN é uma arritmia comum em idosos hospitalizados com pneumonia por COVID-19. Parâmetros clínicos e laboratoriais avaliados na admissão são preditores de FAN durante internação.
Abstract Background New-onset atrial fibrillation (NOAF) occurs in patients hospitalized due to COVID-19. It is still unknown whether clinical and laboratory data assessed upon hospital admission have predictive value for NOAF. Objectives To analyze, upon hospital admission, variables with predictive potential for the occurrence of NOAF in patients with COVID-19 pneumonia. Methods Observational, retrospective, case-control study. Electronic medical reports of consecutive patients, 60 years of age or older, hospitalized due to COVID-19 pneumonia between March 1st and July 15th, 2020, were reviewed. Non-paired Student or chi-squared tests compared variables. A Cox proportional hazard model was employed to identify independent predictors of NOAF. P value < 0.05 was considered statistically significant. Results Among 667 patients hospitalized due to COVID-19, 201 (30.1%) fulfilled the inclusion criteria. NOAF was documented in 29 patients (14.4%), composing group 1. Group 2 was composed of 162 patients without NOAF. Ten patients were excluded due to the AF rhythm upon hospital admission. In groups 1 and 2, there were differences in overall in-hospital survival rate (24.1 % vs. 67.9%; p<0.001), length of stay in ICU (11.1 ± 10.5 days vs. 4.9 ± 7.5 days; p=0.004) and need for mechanical ventilation rate (82.9% vs. 32.7%; p<0.001). In the Cox model, age > 71 y/o (HR=6.8; p<0.001), total leukocyte count ≤ 7,720 cels.μL-¹ (HR=6.6; p<0.001), serum [Na+] ≤ 137 mEq.L-¹ (HR=5.0; p=0.001), SAPS3 score > 55 (HR=5.6; p=0.002), and disorientation (HR=2.5; p=0.04) on admission were independent predictors of NOAF. Conclusion NOAF is a common arrhythmia in elderly hospitalized patients with COVID-19 pneumonia. Clinical and laboratory parameters evaluated on admission have a predictive value for the occurrence of NOAF during hospitalization.
ABSTRACT
Objective To investigate the clinical features of patients with recurrent acute pancreatitis(RAP)complicated with metabolic syndrome(MS)and the influencing factors of severe disease.Methods The clini-cal data of 382 RAP patients admitted to the hospital from June 2012 to June 2022 were retrospectively analyzed,and they were divided into the MS group(n=142)and the non-MS group(n=240)according to whether they were combined with MS,and into the severe group(n=29)and the non-severe group(n=353)according to the severity.The general data,serological parameters[triglyceride(TG),total cholesterol(TC),white blood cell count(WBC),neutrophil to lymphocyte ratio(NLR),blood calcium,D-dimer(D-D),lactate dehydrogen-ase(LDH),ALT,AST]and ICU occupancy rate and total length of stay were compared among all groups.Bi-nary logistic regression was used to analyze the independent influencing factors of RAP development into se-vere disease,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for RAP development.Results Hyperlipidemia was the most common cause of RAP in MS group(66.2％),and biliary origin was the most common cause of RAP in non-MS group(44.6％).There was sig-nificant difference among different causes was statistically significant(P＜0.05).There were significant differences in age,gender,proportion of hypertension,diabetes,MS,length of stay,LDH,blood calcium,D-D and NLR levels between the critical and non-critical groups(P＜0.05).The area under the curve(AUC)of blood calcium,D-D,LDH,NLR and combined diagnosis were 0.759,0.777,0.710,0.621,and 0.841,respec-tively.The AUC of single diagnosis had a certain predictive value,but combined diagnosis had a higher predic-tive value.Conclusion The most common cause in the MS group was hyperlipidemia,and the most common cause in the non-MS group was biliary.Blood calcium.D-D,LDH,NLR are reliable indicators to predict the development of RAP into severe disease,and the accuracy of combined diagnosis is higher.
ABSTRACT
Objective To investigate the predictive value of the expression levels of YY1 transcription fac-tor(YY1)and microRNA(miR)-181a-5p in peripheral blood mononuclear cell for adverse pregnancy out-comes in gestational diabetes mellitus(GDM).Methods A total of 200 patients with GDM were enrolled as the GDM group.100 healthy pregnant women who underwent prenatal examinations during the same period were selected as the control group.The expressions levels of YY1 and miR-181a-5p in peripheral blood mono-nuclear cell were detected by fluorescent quantitative PCR.Receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of YY1 and miR-181a-5p for adverse pregnancy outcomes in GDM pa-tients.Results Compared with the control group,the expression levels of YY1 and miR-181a-5p in peripheral blood mononuclear cell of GDM group were obviously decreased(P＜0.05),and the incidence rates of post-partum hemorrhage,macrosomia and neonatal hypoglycemia in GDM group were obviously higher(P＜0.05).Multivariate Logistic regression analysis showed that age and poor blood glucose control were inde-pendent risk factors for adverse pregnancy outcomes in GDM patients(P＜0.05),and the expression levels of peripheral blood mononuclear cell YY1 and miR-181a-5p were independent protective factors for adverse preg-nancy outcomes in GDM patients(P＜0.05).ROC curve results showed that the area under the curve(AUC)of the expression levels of YY1 and miR-181a-5p in peripheral blood alone and in combination in predicting ad-verse pregnancy outcomes in GDM patients was 0.717,0.751 and 0.832,respectively,and the AUC of their combination was obviously higher than that of the two alone(P＜0.05).Conclusion The decreased expres-sion levels of YY1 and miR-181a-5p in peripheral blood mononuclear cell of GDM patients could increase the risk of adverse pregnancy outcomes,YY1 and miR-181a-5p are closely related to adverse pregnancy outcomes in GDM patients,and both could be used as predictors of adverse pregnancy outcomes in GDM patients.
ABSTRACT
Objective To investigate the relationship between serum microRNA(miR)-137 and miR-21 ex-pression and hypertensive retinopathy(HR).Methods A total of 123 hypertensive patients admitted to the hospital from March 2020 to August 2022 were selected as the hypertensive group and divided into HR and non-HR groups according to whether they were concomitant with HR,and another 58 healthy people who un-derwent the physical examination during the same period were selected as the control group.Clinical data of HR patients were collected and serum miR-137 and miR-21 expression was detected by real-time fluorescent quantitative PCR.The influencing factors of concurrent HR in hypertensive patients were analyzed,and receiv-er operating characteristic(ROC)curve was used for analzing predictive value of serum miR-137 and miR-21 expression in hypertensive patients with concurrent HR.Results Serum miR-137 and miR-21 relative expres-sion levels were higher in the hypertensive group than those in the control group(P<0.05).The incidence rate of HR in 123 hypertensive patients was 25.20%(31/123).Multivariate Logistic regression analysis showed that prolonged duration of hypertension and elevated systolic pressure,diastolic pressure,miR-137 rel-ative expression level,and miR-21 relative expression level were independent risk factors for HR in hyperten-sive patients(P<0.05).ROC curve analysis showed that the area under the curve(AUC)of serum miR-137 combined with miR-21 in predicting HR in hypertensive patients was 0.840,which was greater than 0.735 and 0.732 of the single detection of miR-137 and miR-21(P<0.05).Conclusion High expression of serum miR-137 and miR-21 is closely associated with hypertension complicating HR and may be an auxiliary predictor of HR.
ABSTRACT
Objective To investigate the influencing factors of adverse pregnancy outcomes in patients with preeclampsia and the predictive value of serum trace elements in the second trimester.Methods A total of 98 patients with preeclampsia admitted to Qujing First People's Hospital from January 2019 to June 2022 were enrolled in the study.Patients were divided into poor outcome group and good outcome group according to whether they had adverse pregnancy outcomes.The clinical data of all patients enrolled in the study were col-lected and the serum levels of trace elements calcium,copper,zinc and iron were detected in the second trimes-ter.Univariate analysis and multivariate Logistic regression were used to analyze the influencing factors of ad-verse pregnancy outcomes in patients with preeclampsia.The levels of serum trace elements in the second tri-mester of pregnancy were compared between the poor outcome group and the good outcome group.The re-ceiver operating characteristic(ROC)curve was used to evaluate the predictive value of serum trace elements calcium,copper,zinc and iron for adverse pregnancy outcomes in patients with preeclampsia.Results Univari-ate analysis showed that compared with the good outcome group,the poor outcome group had significantly higher systolic blood pressure,24 h urinary protein quantitation,and D-dimer level(P＜0.05)and significantly less gestational age and platelet count at admission(P＜0.05).Multivariate Logistic regression analysis showed that 24 h urinary protein quantification,D-dimer and platelet count were the influencing factors of ad-verse pregnancy outcomes in patients with preeclampsia(P＜0.05).The levels of serum trace elements calci-um,copper,and zinc in the poor outcome group were significantly lower than those in the good outcome group(P＜0.05),and the level of iron was significantly higher than that in the good outcome group(P＜0.05).ROC curve analysis showed that the areas under the curves(AUCs)of serum calcium,copper,zinc,and iron in the second trimester of pregnancy for predicting adverse pregnancy outcomes in preeclampsia patients were 0.830(95％CI:0.780-0.880),0.855(95％CI:0.805-0.905),0.847(0.797-0.897)and 0.861(95％CI:0.811-0.911),respectively.Conclusion Adverse pregnancy outcomes in patients with preeclampsia are re-lated to 24 h urine protein,D-dimer and platelet count.The levels of serum trace elements calcium,copper,zinc and iron in the second trimester of pregnancy change significantly in patients with adverse pregnancy out-comes,which may become predictive markers of adverse pregnancy outcomes.
ABSTRACT
Objective To investigate the predictive value of tissue plasminogen activator(t-PA),chro-mogranin A(CgA),and lipoprotein related phospholipase A2(LP-PLA2)in serum for major adverse cardio-vascular event(MACE)after percutaneous coronary intervention(PCI).Methods A total of 120 patients with coronary heart disease who underwent PCI in the hospital from August 2020 to August 2022 were en-rolled in the study.According to whether MACE occurred within 1 year after PCI,the patients were divided into MACE group(33 cases)and non-MACE group(87 cases).The levels of serum t-PA,CgA,LP-PLA2 and clinical data were compared between the MACE group and the non-MACE group.Multivariate Logistic regres-sion was used to analyze the risk factors of MACE after PCI.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of t-PA,CgA and LP-PLA2 alone or in combination for MACE after PCI.Results The proportion of patients with smoking history,NT-proBNP,CgA,LP-PLA2,and the propor-tion of patients with hypertension in the MACE group were higher than those in the non-MACE group(P＜0.05),while left ventricular ejection fraction(LVEF)and t-PA were lower than those in the non-MACE group(P＜0.05).There were no significant differences in age,gender composition,serum creatinine,triglyc-erides(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),drinking history,NYHA cardiac function classification,combined diabetes,application of aspirin,and application of clopidogrel between the two groups(P＞0.05).Multivariate Logistic regression analysis showed that smoking history,increased NT-proBNP,hypertension,decreased LVEF,decreased t-PA,increased CgA and increased LP-PLA2 were risk factors for MACE after PCI(P＜0.05).ROC curve analysis showed that the areas under the curves(AUCs)of serum t-PA,CgA and LP-PLA2 alone or in combination for predicting MACE after PCI were 0.785(95％CI:0.693-0.877),0.678(95％CI:0.564-0.791),0.730(95％CI:0.636-0.824),0.888(95％CI:0.830-0.946),respectively.The efficacy of combined prediction was bet-ter than those of single detections(P＜0.05).Conclusion The lower the serum t-PA level is and the higher the CgA and LP-PLA2 levels are,the greater the risk of MACE after PCI is.The combination of the three in-dicators has higher value in predicting MACE after PCI.
ABSTRACT
Objective:To investigate associations between cardiac biomarkers with stroke severity and short-term outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Affiliated Hospital of Qingdao University from June 2018 to February 2024 whose etiological classification was large artery atherosclerosis (LAA), small vessel occlusion (SVO) or cardioembolism (CE) were included retrospectively. According to the National Institutes of Health Stroke Scale score at admission, patients were divided into mild stroke group (≤8) and moderate to severe stroke group (>8). According to the modified Rankin Scale score at discharge, patients were divided into good outcome group (≤2) and poor outcome group (>2). Multivariate logistic regression analysis was used to determine the independent correlation between cardiac biomarkers and short-term outcome. The predictive value of cardiac biomarkers for poor outcome in patients with AIS and different stroke etiology subtypes were evaluated using receiver operating characteristic (ROC) curves. Results:A total of 2 151 patients with AIS were enrolled, including 1 256 males (58.4%), aged 67.40±11.34 years. 1 079 patents were LAA type (50.2%), 679 were SVO type (31.6%), and 393 were CE type (18.3%); 1 223 were mild stroke (56.86%) and 928 (43.14%) were moderate to severe stroke; 1 357 patients (63.09%) had good short-term outcome, and 794 (36.91%) had poor short-term outcome. Multivariate logistic regression analysis showed that N-terminal pro-B type natriuretic peptide (NT-proBNP), NT-proBNP/creatine kinase (CK) isoenzyme MB (CK-MB) ratio, and CK-MB/CK ratio were independent risk factors for poor short-term outcome. ROC curve analysis shows that the CK-MB/CK ratio had a higher predictive value for short-term poor outcome in patients with AIS (the area under the curve, 0.859, 95% confidence interval 0.839-0.879). Various cardiac biomarkers had a higher predictive value for short-term outcome of CE type and LAA type, but the predictive value for short-term outcome of SVO type was lower. Conclusions:Cardiac biomarkers are associated with the severity and poor outcome of AIS. NT-proBNP/CK-MB and CK-MB/CK ratios have higher predictive value for short-term poor outcome of AIS, especially in patients with CE type.
ABSTRACT
Objective To investigate the value of single photon emission computed tomography/computed tomography(SPECT/CT)fusion imaging for post-implantation dose verification of 125I particles in patients with bone metastases.Methods Forty patients with metastatic bone tumors treated with 125I particles implantation were selected.Within 24 h after 125I particles implantation,patients underwent SPECT/CT fusion imaging and the radioactivity per unit(RPU)was calculated.The treatment planning system(TPS)was then used to obtain the isodose profiles of SPECT/CT fusion imaging results and to calculate the tumor target coverage.The patient's preoperative and postoperative 1 month clinical outcomes,including local tumour remission,pain assessment,quality of life and serum alkaline phosphatase(ALP)levels were compared,and a receiver operating characteristic(ROC)curve was applied to evaluate the predictive value of tumor target coverage on postoperative outcomes.Results The mean number of particles implanted in the target area was 32.52±12.87.Within 24 h of 125I particles implantation,SPECT/CT fusion imaging analysis confirmed a strong positive correlation between the RPU of the radioactive concentration area and the mean dose received by the patient(r=0.786,P<0.05).The predicted area under the curve(AUC)for local tumor remission,pain relief,quality of life improvement and change in ALP levels was 0.789,0.757,0.804 and 0.833,respectively.Conclusion SPECT/CT fusion imaging can be used for postoperative dose verification of 125I particles for metastatic bone tumors and has some predictive value for clinical outcomes.
ABSTRACT
Objective To investigate the risk factors of postoperative complications in patients with spinal tuberculosis and analyze the value of prognostic nutritional index(PNI)in predicting these complications.Methods The clinical data of 156 patients with spinal tuberculosis who underwent surgery in the Affiliated Hospital of Zunyi Medical University from January 2018 to July 2022 were retrospectively analyzed.The patients were divided into a complication group and a non-complication group based on the presence or absence of postoperative complications.Baseline data,laboratory indicators,and surgery-related indicators were compared between the two groups.The risk factors for postoperative complications in spinal tuberculosis were analyzed,and receiver operating characteristic(ROC)curves were plotted to evaluate the predictive value of PNI for postoperative complications in the patients.Results Among all of 156 patients,68 contracted a total of 82 instances of postoperative complications,with an incidence of 43.59%.Coinfection with pulmonary tuberculosis,preoperative anti-tuberculosis treatment duration more than 4 weeks,surgical operation duration,and drainage days were identified as independent risk factors for postoperative complications in spinal tuberculosis(P<0.05).On the other hand,a higher PNI was found to be a protective factor against postoperative complications of the spinal tuberculosis(P<0.05).The area under the ROC curve for PNI predicting postoperative complications ofthe spinal tuberculosis was 0.805.Conclusion The risk of postoperative complications in patients with spinal tuberculosis is subject to such factors ascoexistence of pulmo-nary tuberculosis,preoperative anti-tuberculosis treatment duration,surgery duration,drainage duration,and preoperative PNI.Preoperative PNI has a certain value for predicting the postoperative complications in the patients.
ABSTRACT
Objective To investigate the changes in the levels of serum high-sensitivity C-reactive protein(hs-CRP)and soluble fms-like tyrosine kinase-1(sFlt-1)in hypertensive disorder of pregnancy(HDP)patients with fetal growth restriction(FGR),and to evaluate their predictive value for FGR.Methods A total of 137 HDP patients admitted to the Obstetrics De-partment of Ganzhou Maternal and Child Health Hospital from December 2021 to May 2023 were selected as the study subjects.According to whether their fetuses had growth restriction,they were divided into the restricted group(n=46)and the non-re-stricted group(n=91).The general information and serum levels of hs-CRP and sFlt-1 were collected and analyzed.Multiple lo-gistic regression analysis was used to identify the influencing factors for fetal growth restriction in HDP patients,and receiver oper-ating characteristic(ROC)curve was plotted to evaluate the predictive value of serum hs-CRP and sFlt-1 levels for fetal growth restriction in HDP patients.Results Univariate analysis showed that the serum levels of folic acid(FA),vitamin B12(VitB12),and placental growth factor(PIGF)in the restricted group were lower than those in the non-restricted group,while the serum lev-els of hs-CRP and sFlt-1 were higher than those in the non-restricted group,with statistically significant differences(P＜0.05).Multivariate analysis showed that serum hs-CRP,sFlt-1,and PIGF levels were independent risk factors for fetal growth restriction in HDP patients.The H-L test of the model showedx2=7.014,P=0.535,indicating a good fit.The area under the ROC curve(AUC)was 0.932,with a 95％CI of 0.889-0.975(P＜0.05),a sensitivity of 93.50％,and a specificity of 89.00％.Conclusion Serum hs-CRP and sFlt-1 levels are upregulated in HDP patients with fetal growth restriction,indicating their good predictive value for the occurrence of fetal growth restriction.
ABSTRACT
Objective:To investigate the correlation between the annual professional proficiency test results and the theoretical examination score of completion assessment in standardized residency training, as well as the value of the annual professional proficiency test results in predicting whether a resident passes the theoretical examination of completion assessment.Methods:The residents who participated in the annual professional proficiency test of residency training in Affiliated Hospital 2 of Nantong University in 2019-2021 and the completion assessment of residency training in 2020-2022 were selected as subjects, and related data were collected, including sex, education background, personnel type, training specialty, the results of annual professional proficiency test, and the theoretical examination score of completion assessment. According to whether the resident passed the theoretical examination of completion assessment, they were divided into passed group and failed group. SPSS 19.0 was used to perform the chi-square test, the independent samples t-test, and the binary logistic regression analysis; the Pearson correlation coefficient was used for correlation analysis; the sensitivity analysis was represented by ROC curve. Results:Compared with the residents who passed the theoretical examination of completion assessment, the residents who did not pass the examination had a significant reduction in the proportion of the residents from our hospital and a significant increase in the proportion of the residents commissioned by foreign institutions ( χ 2=7.00, P=0.008). The passed group had a significantly higher national percentile of annual professional proficiency test score than the failed group (43.46%±26.61% vs. 23.40%±18.71%, t=6.02, P<0.001). The national percentile of annual professional proficiency test score was positively correlated with the theoretical examination score of completion assessment ( r=0.43, P<0.05). The source of residents commissioned by foreign institutions and the low percentile of annual professional proficiency test score were independent risk factors for failing the theoretical examination of completion assessment ( P=0.020 and P<0.001). The national percentile of annual professional proficiency test score had an area under the ROC curve of 0.73 (95% CI: 0.65-0.80) in predicting the outcome of theoretical examination and had a certain predictive value with a cut-off value of 15.1%. Conclusions:In addition to strengthening homogenization and professional base management for residency training, it is necessary to make full use of the results of annual professional proficiency test in standardized residency training and timely check the professional knowledge of the residents whose a national percentile of <15.1%, so as to effectively improve the pass rate of theoretical examination and the quality of training.
ABSTRACT
Despite a more significant improvement in survival rates of premature and high-risk infants, surviving infants face a high risk of developing neurodevelopmental disorders such as cerebral palsy.Infant development is characterized by a dynamic continum, which makes it difficult to classify a child′s level of motor development as normal or abnormal on the basis of a single examination.This article provides a review of advances in the application of the predictive validity of General Movement Assessment (GMA) and the Alberta Infant Motor Scale (AIMS) in the early assessment and follow-up of infants and toddlers, in order to intervene in a timely manner with young children at potential motor risk.
ABSTRACT
Objective:To investigate the value of multiparameter MRI in predicting secondary acute cerebral infarction in patients with transient ischemic attack (TIA).Methods:A total of 358 patients with TIA admitted to Department of Neurology, Affiliated Hospital of Chengde Medical College from April 2020 to May 2022 were selected. They were divided into cerebral infarction group ( n=114) and non-cerebral infarction group ( n=244) according to whether they had secondary acute cerebral infarction within 3 months of follow up. Differences in multiparameter MRI (number of unstable plaques, reference vessel area/plaque area, internal carotid artery stenosis rate, intracranial arterial stenosis rate, ratio of unstable plaques, lumen area of the most stenotic responsible vessel, and wall area of the most stenotic responsible vessel) at the consultation time were collected and compared between the 2 groups; correlations of multiparameter MRI with secondary acute cerebral infarction was evaluated by partial regression analysis; value of multiparameter MRI in predicting secondary acute cerebral infarction in TIA patients was evaluated by receiver operating characteristic (ROC) curve. Results:Reference vessel area/plaque area, intracranial arterial stenosis rate, ratio of unstable plaques and wall area of the most stenotic responsible vessel in the infarction group were significantly higher/larger than those in the non-cerebral infarction group, and lumen area of the most stenotic responsible vessel in the infarction group was significantly smaller than that in the non-cerebral infarction group ( P<0.05). After adjusting for age and gender, reference vessel area/plaque area, intracranial arterial stenosis rate, ratio of unstable plaques and wall area of the most stenotic responsible vessel were positively correlated with secondary acute cerebral infarction, while lumen area of the most stenotic responsible vessel was negatively correlated with secondary acute cerebral infarction ( P<0.05); AUC of the combination of above parameters was 0.900, which was significantly greater than that of reference vessel area/plaque area (0.724), intracranial arterial stenosis rate (0.751), unstable plaque occurrence rate (0.812), lumen area of the most stenotic vessel (0.771), and wall area of the most stenotic vessel (0.763), respectively ( P<0.05). Conclusion:Multiparameter MRI analyzing reference vessel area/plaque area, intracranial arterial stenosis rate, ratio of unstable plaques, lumen area of the most stenotic responsible vessel, and wall area of the most stenotic responsible vessel can effectively predict secondary acute cerebral infarction in TIA patients.
ABSTRACT
Objective To establish an individual Nomgram model for predicting the risk of coronary heart disease complicated with pulmonary hypertension. Methods From January 2017 to December 2021 , 352 patients with coronary heart disease (CHD) complicated with pulmonary hypertension in our hospital were selected, and 352 patients with coronary heart disease but without pulmonary hypertension were selected as the control group. The clinical baseline data of the two groups were analyzed first, and then logistics multivariate analysis was performed. To explore the risk factors of coronary heart disease complicated with pulmonary hypertension, the Nomgram model was established to predict the risk, and the predictive value of the model was tested by receiver characteristic curve (ROC). Results Logistics multivariate analysis showed that alcoholism, smoking, stroke history, hypertension course, CHD course, PASP, HCT, PaCO2, D-dimer, NIHSS score and low PaO2 were all independent risk factors for CHD complicated with pulmonary hypertension. Nomgram model prediction results for patients with coronary heart disease showed that Alcohol abuse, smoking, stroke history, duration of hypertension (5.66 years), duration of coronary heart disease (2.12 years), NIHSS (12.33 points), PASP (75.22mmHg), HCT (33.22%), PaCO2 (56.11mmHg), D-dimer (255.12μg/L), PaO2 (56.22mmHg) is a risk factor for coronary heart disease complicated with pulmonary hypertension. ROC curve showed that the area under the prediction curve of Nomgram model for coronary heart disease complicated with pulmonary hypertension was 0.675. Conclusion Nomgram model can predict pulmonary hypertension in patients with coronary heart disease to a certain extent.
ABSTRACT
Objective:To investigate the influential factors of patients' expectations for clinical decision-making during digestive endoscopy.Methods:A total of 120 patients who underwent digestive endoscopy were admitted to the Endoscopy Center of Zhejiang Provincial People's Hospital from January 2020 to January 2022. Their general information was collected, and their clinical decision-making expectations were evaluated using the Control Preference Scale (CPS). The influential factors of clinical decision-making expectations were determined using multiple linear regression analysis.Results:The total CPS score for 120 patients undergoing digestive endoscopy was (50.72 ± 5.48) points, including (14.12 ± 1.48) points for information needs, (25.17 ± 3.52) points for communication needs, and (11.43 ± 2.04) points for decision-making needs. Univariate analysis showed that the CPS score of patients undergoing digestive endoscopy was related to gender, age, marital status, educational level, number of children, and type of visit ( t = 2.68, 2.61, 2.82, 3.28, 3.61, 2.39, all P < 0.05). Multiple linear regression analysis showed that gender, age, educational level, and type of visit were the influential factors of clinical decision-making expectations for patients undergoing digestive endoscopy ( β = -0.71, 1.07, 0.53, -1.15, all P < 0.05). Conclusion:Gender, age, educational level, and type of visit are influential factors of patients' expectations for clinical decision-making during digestive endoscopy. Patients have a clear need for communication during clinical decision-making, and medical staff can strengthen communication with patients, correctly guiding them to participate in clinical decision-making expectations.
ABSTRACT
Objective:To analyze the predictive value of von Willebrand factor (vWF) for venous thromboembolism (VTE) of patients in intensive care unit (ICU) by using propensity score matching (PSM).Methods:Patients admitted to ICU of the Second Affiliated Hospital of Kunming Medical University from December 2020 to June 2022 who stayed in ICU for ≥72 hours and underwent daily bedside vascular ultrasound screening were included. Baseline data such as age, gender, primary disease, and chronic comorbidities were collected. Coagulation indexes before admission to ICU and 24 hours and 48 hours after ICU admission were collected, including prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), international normalized ratio (INR), fibrinogen (Fib), fibrin monomer (FM), vWF, D-dimer, antithrombin Ⅲ (ATⅢ), etc. Patients were divided into VTE group and non-VTE group according to whether they had VTE or not [diagnosis of VTE: patients underwent daily ultrasound screening of bedside blood vessels (both upper and lower limbs, visceral veins), and those suspected of having thrombosis were confirmed by ultrasonographer or pulmonary angiography]. Using PSM analysis method, the VTE group was used as the benchmark to conduct 1 : 1 matching of age, whether there was malignant tumor, whether there was infection, whether there was diabetes, and coagulation indicators before admission to ICU. Finally, the cases with balanced covariates between the two groups were obtained. The risk factors of VTE were analyzed by multivariate Logistic regression analysis. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of vWF in the occurrence of VTE in critically ill patients.Results:A total of 120 patients were enrolled, of which 18 (15.0%) were diagnosed with VTE within 72 hours after admission to ICU, and 102 (85.0%) were not found to have thrombus in ICU. Before PSM, there were significant differences in age, gender, proportion of malignant tumor and infection, and coagulation indexes between VTE group and non-VTE group. After PSM, 14 pairs were successfully matched, and the unbalanced covariables between the two groups reached equilibrium. Multivariate Logistic regression analysis showed that vWF was an independent risk factor for VTE at 48 hours after ICU admission in critically ill patients [odds ratio ( OR) = 1.165, 95% confidence interval (95% CI) was 1.000-1.025, P = 0.004]. ROC curve analysis showed that the area under the ROC curve (AUC) of vWF at 48 hours after ICU admission for predicting VTE was 0.782, 95% CI was 0.618-0.945, P = 0.007. When the optimal cut-off value was 312.12%, the sensitivity was 67.7% and the specificity was 93.0%. Conclusion:Dynamic monitoring of vWF is helpful to predict the occurrence of VTE in ICU patients, and vWF at 48 hours after ICU admission has certain value in predicting the occurrence of VTE.

Abstract OBJECTIVE: To describe the sociodemographic, clinical and pathological characteristics and results of the patent blue sentinel lymph node technique in early breast cancer surgery. And to report the experience in identifying the sentinel lymph node in early breast cancer using the 2.5% patent blue technique. MATERIALS AND METHODS: Retrospective and analytical study consisting of the evaluation of the clinical records of patients diagnosed with early breast cancer, without clinical or radiological suspicion of axillary involvement, seen between June 2022 and June 2023 at the Oncological Gynaecology Service of the UMAE Hospital de Ginecoobstetricia, Centro Médico Nacional de Occidente of the IMSS. The dye injection site was subdermal periareolar, and the identified lumps were examined in the transoperative period. The percentage of identification, false negative rates and negative predictive value of the method were analysed. RESULTS: Ninety-five sentinel node biopsies were analysed. Axillary lymphadenectomy was performed only in patients with sentinel lymph node metastasis confirmed at surgery and in those in whom no stained nodes were identified due to non-migration of the dye. The mean age of the patients was 57.1 years range 25 to 78 years. The tumour size was less than 3 cm. Sixty-four patients 67% underwent mastectomy, compared with 31 who underwent breast-conserving surgery 33%. Fifty-seven of the 95 patients were staged as AI; the most common molecular subtype was compatible with luminal A in 49%. CONCLUSIONS: Sentinel lymph node biopsy with patent blue is a rapid, simple, accurate and inexpensive technique for identifying axillary disease in early breast cancer. The results reported here represent an initial evaluation of the technique in our service.
