ObjectiveThe total cavopulmonary connection (TCPC) offers a palliation for the hemodynamic derangements associated with congenital heart lesions characterized by a single functional ventricle, but it may cause acute hepatic injury because of the special physiology. The objective of this study was to characterize hepatic function and its relationship to cardiac function in children who had undergone the Fontan procedure. MethodsWe retrospectively analyzed 114 children who had undergone TCPC operation in Shanghai Children's Medical Center between January 2013 and March 2014. There were 65 males and 49 females with a median age of 3.8 years (range 2.5 to 13.2) and a median weight of 14.8 kg (range 12.0 to 33.0). The study cohort was further divided into three groups according to the Child-Pugh classification. The total scores were calculated regarding to ascite, bilirubin, albumin, and international normalized ratio (INR). The scores from 4 to 5 were classified in Child A group, from 6 to 8 classified in Child B group, from 9 to 11 classified in Child C group. Thirty-four patients met criteria for Child Class A, 53 patients for Child Class B, and 27 patients for Child Class C. The univariate analysis and multivariable logistic regression model were used to compare demographic, anatomic, and physiological variables among the three groups. ResultsWithin the study population, 80 patients of Child B group and Child C group met criteria for acute hepatic injury. Univariate risk factors for acute hepatic injury included longer total bypass time (P=0.044), longer aortic cross-clamping time (P=0.005), longer ventilation time (P=0.000), higher postoperative mean pulmonary arterial pressure (P=0.000), elevated N-terminal pro-brain natriuretic peptide (P=0.001), higher vasoactive inotropic score (P=0.000), lower mixed venous oxygen saturation (SvO2, P=0.000) and arterial oxygen saturation (P=0.001), higher incidence of arrhythmia (P=0.000), and low cardiac output syndrome (P=0.003), the need of peritoneal dialysis (P=0.000). In the multivariable logistic model, the need for peritoneal dialysis (OR=17.018, 95%CI 5.117-56.602) and the lower postoperative SvO2 (OR=0.922, 95%CI 0.871-0.976) were two independent risk factors for acute hepatic injury after the TCPC. ConclusionThe need for peritoneal dialysis and lower postoperative SvO2 may represent the compound effects of multiple risk factors including preoperative hemodynamic and a marked hepatic vascular inflammatory response to surgery and cardiopulmonary bypass, which in turn may mediate acute hepatic injury.
Objective To define risk factors of nosocomical pneumonia (NP) in elderly in-patients. Methods Two hundred elderly in-patients were selected in the Geriatric Department of West China Hospital from January 1999 to June 2002. Among them, 100 patients developed NP during their hospital days and the others didn’t have the episodes of NP at the same time. The following factors were analyzed: sex, age, multiple underline diseases and their severity, smoking, activity of daily life, conscious status, aspiration, nasogastrial intubations, antibiotics use and hospitalization. SPSS 10.0 was used for Logistic regression analysis to determine the factors significantly associated with the development of NP. Results The following factors were significantly associated with the development of NP in the logistic regression analysis: aspiration [OR 28.452, 95%CI (3.793 to 213.447)],multiple diseases [OR 17.157, 95%CI (2.734 to 107.651)], multiple antibiotics use [OR 6.396, 95%CI (1.861 to 21.980)], smoking [OR 1.774, 95%CI (1.211 to 2.600)] and prolonged hospitalization [OR 1.134, 95%CI (1.081 to 1.189)]. Conclusions Aspiration, multiple diseases, multiple antitiotics use, smoking and prolonged hospitalization are closely related to NP in elderly in-patients. Cautionary medical measures and shortening hospitalization were the key factors to decrease the incidence of NP for the patients in Geriatric Department.
ObjectiveTo analyze the risk factors for pancreatic fistula following pancreaticoduodenectomy. MethodThe clinical data of 150 patients underwent pancreaticoduodenectomy in this hospital from January 2011 to January 2014 were reviewed, and the potential factors for pancreatic fistular were evaluated by both univariate and multivariate analysis. ResultsThe incidence of pancreatic fistula was 12.7% (19/150). Univariate analysis results showed that the age, preoperative high bilirubin level, texture of the remnant pancreas, diameter of wirsung, operative time were associated with pancreatic fistula following pancreaticoduodenectomy (P < 0.05). Multivariate logistic regression analysis results revealed that the texture of the remnant pancreas, diameter of wirsung, and operative time were the inde-pendent risk factors (P < 0.05) for pancreatic fistula following pancreaticoduodenectomy. ConclusionsTexture of the remnant pancreas, diameter of wirsung, operative time are independent risk factors for pancreatic fistula following pancreaticoduodenectomy. Rich experience and skilled surgical procedures could effectively reduce the incidence of pancreatic fistula.
Heart valve disease is one of the three most common cardiac diseases,and the patients undergoing valve surgery have been increasing every year. Due to the high mortality,increasing number of valve surgeries,and increasing economic burdens on public health, a lot of risk models for valve surgery have been developed by various countries based on their own clinical data all over the world,which aimed to regulate the preoperative risk assessment and decrease the perioperative mortality. Over the last 10 years, a number of excellent risk models for valve surgery have finally been developed including the Society of Thoracic Surgeons(STS), the Society of Thoracic Surgeons’ National Cardiac Database (STS NCD),New York Cardiac Surgery Reporting System(NYCSRS),the European System for Cardiac Operative Risk Evaluation(EuroSCORE),the Northern New England Cardiovascular Disease Study Group(NNECDSG),the Veterans Affairs Continuous Improvement in Cardiac Surgery Study(VACICSP),Database of the Society of Cardiothoracic Surgeons of Great Britain and Ireland(SCTS), and the North West Quality Improvement Programme in Cardiac Interventions(NWQIP). In this article, we reviewed these risk models which had been developed based on the multicenter database from 1999 to 2009, and summarized these risk models in terms of the year of publication, database, valve categories, and significant risk predictors.
Objective To explore risk factors of stroke-associated pneumonia (SAP) for elderly stroke patients in ICU, and analyze the predictive value of human leukocyte antigen-DR (HLA-DR) on monocytes for SAP. Methods During January 2015 to August 2016, 155 elderly patients with stroke were recruited. The level of monocyte HLA-DR expression was measured after admission and the incidence of SAP was recorded. The risk factors for SAP were analyzed by univariate and multivariate analysis. ROC curve was drawn to analyze prognostic value of HLA-DR. Results SAP occurred in 75 cases with occurrence rate of 48.4%, including 42 early-onset cases and 33 later-onset cases. Age (OR=11.532), Glasgow Coma Scale (OR=7.124), dysphagia (OR=8.846), mechanical ventilation (OR=15.184), atrial fibrillation (OR=7.869), smoking history (OR=11.784), diabetes (OR=7.185) were independent risk factors (all P<0.05). The expression rate of monocyte HLA-DR in the SAP patients was significantly lower than those in the patients without SAP (allP<0.05). Through the ROC curve analysis, the expression rate of HLA-DR that below 78.65% was the optimum cut-off value for prediction of SAP with the area under ROC curve of 0.922, the sensitivity of 80.0% and the specificity of 85.0%. The sensitivity to predict early-onset SAP was 90.5% (38/42), and to predict later-onset SAP was 66.7% (22/33). Conclusions Age, severe coma, dysphagia, mechanical ventilation, atrial fibrillation, smoking history and diabetes are risk factors for SAP in elderly stroke patients in ICU. The detection of monocyte HLA-DR has reference value for early prediction of SAP especially for early-onset SAP with higher sensitivity.
Epilepsy is one of the most common neurological diseases in children, about 2/3 can be seizure-free after anti-seizure medications (ASMs) treatment, but there are still some drug-resistant epilepsy (DRE) need surgical treatment, epilepsy surgery including excision surgery, dissociation surgery and palliative surgery, surgery can make 30%~40% DRE fully controlled. Clinicians usually choose to discontinue ASMs after seizure-free for 1 to 2 years after epilepsy surgery, but there has been controversy about whether to discontinue ASMs after surgery in children with epilepsy, how long to discontinue ASMs, the timing of ASMs withdrawal, and there is still a lack of unified guidelines. This article will comprehensively analyze and summarize the risk of recurrence after ASMs withdrawal in children with epilepsy.
ObjectiveTo explore the clinical application value of antithrombin Ⅲ (ATⅢ) in pulmonary thromboembolism (PTE).MethodsA retrospective study included 204 patients with confirmed PTE who were admitted to Fujian Provincial Hospital from May 2012 to June 2019. The clinical data of the study included basic conditions, morbilities, laboratory examinations and scoring system within 24 hours after admission. The relationship between ATⅢ and PTE in-hospital death was analyzed, and the value of ATⅢ to optimize risk stratification was explored.ResultsFor ATⅢ, the area under receiver operating characteristic curve (AUC) of predicting in-hospital mortality was 0.719, with a cut-off value of 77.7% (sensitivity 64.71%, specificity 80.21%). The patients were divided into ATⅢ≤77.7% group (n=48) and ATⅢ>77.7% group (n=156) according to the cut-off value, and significant statistically differences were found in chronic heart failure, white blood cells count, platelets count, alanine aminotransferase (ALT), albumin and troponin I (P<0.05). According to the in-hospital mortality, patients were divided into a death group (n=17) and a survival group (n=187), and the differences in count of white blood cells, ATⅢ, D-dimer, ALT, albumin, estimated glomerular filtration rate and APACHEⅡ were statistically significant. Logistic regression analysis revealed that ATⅢ≤77.7% and white blood cells count were independent risk factors for in-hospital death. The risk stratification and the risk stratification combined ATⅢ to predict in-hospital death were evaluated by receiver operating characteristic curve, and the AUC was 0.705 and 0.813, respectively (P<0.05). A new scoring model of risk stratification combined with ATⅢ was showed by nomogram.ConclusionsATⅢ≤77.7% is an independent risk factor for in-hospital death, and is beneficial to optimize risk stratification. The mechanism may be related to thrombosis, right ventricular dysfunction and inflammatory response.
ObjectiveTo observe and analyze the risk factors of retinopathy in patients with hypertension in pregnancy.MethodsA retrospective clinical study. From January 2018 to December 2019, 260 patients with hypertension during pregnancy who were hospitalized in the Obstetrics Department of the Third Affiliated Hospital of Guangzhou Medical University were included in the study. All patients underwent fundus color photography examination. Their age, gestational age, course of hypertension, past history, number of pregnancy and childbirth, pre-pregnancy body mass index (BMI) and laboratory blood routine, alanine aminotransferase, aspartate aminotransferase, and urea Nitrogen, creatinine, uric acid, serum albumin concentration, and 24-hour urine protein concentration and urine protein content examination results were collected. Among the 260 patients, there were 60 and 200 patients with or without retinopathy in the fundus, respectively. Patients were divided into retinopathy group and no retinopathy group. The comparison of quantitative data between groups was performed by independent sample t test; the comparison of grade data was performed by Mann-Whitney U nonparametric test. The variable with statistical difference between the two groups was the independent variable, and the two-class logistic regression analysis was performed.ResultsGestational week (t=4.875), pre-pregnancy BMI (t=2.779), highest systolic blood pressure (t=－4.799), lowest systolic blood pressure (t=－4.797), highest diastolic blood pressure (t=－4.226), minimum diastolic blood pressure (t=－4.226), low and high platelet values and their fluctuations (t=7.701, 2.504, －6.083), serum albumin concentration (t=13.255), aspartic acid transaminase (t=－2.272), urea nitrogen (t=－5.117), creatinine (t=－2.735), uric acid (t=－2.130), 24-hour urine protein concentration (t=－7.801) and 24-hour urine protein (t=－7.567) were compared. The difference was statistically significant (P＜0.05). Logoistic regression analysis showed that pre-pregnancy BMI, maximum systolic blood pressure, low platelet value, and serum albumin were related to the occurrence of retinopathy of hypertension in pregnancy (P＜0.05).ConclusionHigh systolic blood pressure, low platelets, and low serum albumin are the risk factors for the occurrence of retinopathy of hypertension in pregnancy.
ObjectiveTo analyze the incidence of bacterial lung infection after orthotopic liver transplantation and its risk factors. MethodsNinety-six patients with end-stage liver disease who underwent liver transplantation from Jan. 2010 to Jun. 2012 in our hospital were retrospectively analyzed. The relationship of preoperative, intraoperative, and postoperative variables with early postoperative bacterial lung infection was explored by multivariate non-conditional logistic regression. ResultsTwenty-nine cases of 96 cases after liver transplantation occurred early bacterial lung infection, and the infection rate was 30.21%(29/96), in which G-aerobic bacteria infection accounted for 65.52%(19/29), and G+ aerobic bacteria accounted for 34.48%(10/29). Preoperative model for end-stage liver disease score(OR=2.165, P=0.001), intraoperative blood transfusion(OR=1.952, P=0.003), average of plasma creatinine during 3 days after operation(OR=1.913, P=0.001), liquid negative balance time during 3 days after operation(OR=0.916, P=0.023), and postoperative hospital stay(OR=1.923, P=0.003) were all associated with early postoperative bacterial lung infection. ConclusionsRetrograde reperfusion in orthotopic liver transplantation patients are susceptible to bacterial lung infections. Improving basic status before operation, controlling volume of intraoperative blood transfusion, the volume of transfusion, and postoperative hospital stay, and improving renal function can reduce incidence of early postoperative bacterial lung infection.
ObjectiveTo explore the risk factors of diabetic retinopathy. MethodsWe retrospectively analyzed the clinical data of 137 patients with diabetes mellitus (DM) from July 2012 to July 2015. According to the situation of retinopathy, the patients were divided into three groups. Forty-three patients without retinopathy were regarded as the control group, 46 non-proliferative retinopathy patients as the observation group, and 48 patients with proliferative retinopathy as the trial group. DM blood pressure, blood glucose, glycosylated hemoglobin, blood lipid, albumin creatinine ratio and other indicators were collected and analyzed, and multiple-factor non-conditional logistic regression analysis was carried out. ResultsGlycosylated hemoglobin, total cholesterol, triglyceride, low density lipoproteincholesterol, high density lipoprotein cholesterol, body mass index, postprandial 2-hour blood glucose and fasting blood glucose were not significantly different among the three groups (P ＞ 0.05) , but the duration of diabetes, vascular endothelial growth factor and urinary albumin creatinine ratio were significantly different (P ＜ 0.05) . The diabetic duration, glycosylated hemoglobin, systolic blood pressure, urinary albumin creatinine ratio and vascular endothelial growth factor were independently associated with diabetic retinopathy (P ＜ 0.05) . ConclusionThe prolonged disease course of diabetic patients, unstable status of blood glucose and blood pressure, and the increase of blood vessel growth factor and vascular endothelial growth factor can cause the development of diabetic retinopathy.
