OBJECTIVE: Obese patients are thought to have an increased risk for complications in coronary artery bypass surgery. Several risk stratification systems do not identify obesity as a variable for risk adjustment. The aim of this study is to evaluate the in-hospital and early (one year) mortality and morbidity in obese and non-obese patients after a CABG in the UMC St Radboud. METHODS: The data of 1130 patients undergoing a myocardial revascularization from January 2000 to August 2002 were analyzed. Obesity was measured by the body mass index (BMI). A BMI>or=30 kg/m2 was defined as obese. We compared 206 obese patients with 924 non-obese patients. Uni- and multivariate analysis were used to analyze the results. The 1-year survival was analyzed using Kaplan-Meier methods. RESULTS: There were no significant differences between obese and non-obese patients according to postoperative myocardial infarction, re-operation for bleeding, in-hospital mortality, renal complications, neurological complications, pulmonary complications, gastrointestinal complications, re-intubation, re-admission on intensive care, ventilation time, days on intensive care, days in hospital and late mortality. Only the incidence of postoperative wound infections was increased in obese patients, 8.3% in the obese versus 4.4% in the non-obese (P=0.02). Multivariate analysis identified obesity only as risk factor for postoperative for wound infections (P=0.04, odds ratio: 1.97). CONCLUSIONS: Obese patients do not have an increased risk of in-hospital and early (1 year) mortality after CABG. However, obese patients have an increased risk of postoperative wound infections compared to non-obese patients. 相似文献

We provide a long-term evaluation of patients enrolled in the EORTC/GIMEMA AML-10 trial which included a total of 2157 patients, 15-60 years old, randomized to receive either daunorubicin (DNR, 50 mg/m2), mitoxantrone (MXR, 12 mg/m2), or idarubicin (IDA, 10 mg/m2) in addition to standard-dose cytarabine and etoposide for induction chemotherapy and intermediate dose cytarabine for consolidation. Younger patients who reached complete remission with complete (CR) or incomplete (CRi) recovery were then scheduled to receive an allogeneic hematopoietic stem cell transplantation (HSCT). That was if they had a HLA-identical sibling donor; in all other cases, an autologous HSCT had to be administered. At an 11-year median follow-up, the 5-year, 10-year and 15-year overall survival (OS) rates were 33.2%, 30.1% and 28.0%, respectively. No significant difference between the three randomized groups regarding OS was observed (P = .38). In young patients, 15-45 years old, no treatment difference (P = .89) regarding OS was observed, while in patients 46-60 years old, MXR and IDA groups had a trend for a longer OS as compared to the DNR group (P = .029). Among younger patients without a favorable MRC cytogenetic risk subgroup who achieved a CR/CRi after induction chemotherapy, those with a HLA-identical sibling donor had higher 10-year and 15-year OS rates than those without. In older patients who reached CR/CRi, the long-term outcomes of those with or without a donor was similar. In conclusion, long-term outcomes of the study confirmed similar OS in the three randomized groups in the whole cohort of patients. 相似文献

Postprandial hypertriglyceridemia associated with insulin resistance is one of the cardiovascular risk factors in obesity and type 2 diabetes. It is not known whether diabetics have a more pronounced postprandial hypertriglyceridemia than obese subjects. Daylong triglyceridemia, representing postprandial lipemia, was determined in obese subjects with and without type 2 diabetes and in lean subjects. Nineteen type 2 diabetics (F/M: 7/12, body mass index [BMI]: 30.6 +/- 5.4 kg/m(2)), 45 obese nondiabetics (F/M: 16/29, BMI: 29.5 +/- 2.6 kg/m(2)) and 78 lean subjects (F/M: 28/50, BMI: 23.7 +/- 2.2 kg/m(2)) measured capillary triglycerides (TGc) during 3 days on 6 fixed time-points each day in an out-of-hospital situation. Daylong TGc profiles were calculated as mean integrated area under the TGc-curve (TGc-AUC). Fasting plasma TG were higher in diabetics and obese nondiabetics (1.81 +/- 0.79 and 1.77 +/- 0.80 mmol/L) compared with lean subjects (1.23 +/- 0.67 mmol/L, P <.001). TGc-AUC was similarly increased in both diabetics and obese nondiabetics (35.0 +/- 12.1 and 35.2 +/- 10.6 mmol.1 h/L) compared with lean controls (25.5 +/- 12.0 mmol.1 h/L, P <.001). Self-reported energy intake was not significantly different between the groups. Fasting TGc (r =.87, P <.001) and waist circumference (r =.51, P <.001) were the parameters best associated with TGc-AUC. Using stepwise multiple regression analysis, fasting TGc, BMI, total cholesterol, and high-density lipoprotein (HDL) cholesterol were the best predictors of TGc-AUC, explaining 77% of the variation. The cut-off level for "normal" TGc-AUC, calculated as the 75th percentile of TGc-AUC in lean subjects, was 30.7 mmol.1 h/L and corresponded with a fasting TGc of 1.8 mmol/L (eg, 1.6 mmol/L in plasma), calculated using univariate regression analysis. In conclusion, daylong triglyceridemia is similarly increased in diabetics and obese nondiabetics compared with lean subjects. Fasting TG and central obesity largely determine daylong triglyceridemia, independent of the presence of type 2 diabetes. Decreasing fasting plasma TG below 1.6 mmol/L could lead to a normalization of postprandial lipemia in obese subjects with and without diabetes. 相似文献

OBJECTIVE: A novel method has been developed to study diurnal triglyceride (TG) profiles using repeated capillary self-measurements in an 'out-of-hospital' situation. We assessed the diurnal capillary TG (TGc) profile in males with mild obesity and evaluated the use of plasma and capillary TG as markers of insulin resistance. DESIGN: Cross-sectional study. SETTING AND SUBJECTS: Fifty-four lean (body mass index, BMI < 25 kg m-2) and 27 mildly obese (25 < BMI < 30 kg m-2), normolipidaemic males measured capillary TG concentrations on six fixed time-points over a 3-day period in an 'out-of-hospital' situation. MAIN OUTCOME MEASURES: The total area under the TGc curve (TGc-AUC) and incremental area under the TGc curve (TGc-IAUC) were used as estimation of diurnal triglyceridaemia. Fasting blood samples were obtained once. Food intake was recorded by all participants. RESULTS: Obese and lean subjects had comparable fasting capillary TG concentrations (1.37 +/- 0.40 mmol L-1 and 1.32 +/- 0.53 mmol L-1, respectively). However, during the day, obese subjects showed a greater TG increase, resulting in significantly higher TGc-AUC (27.1 +/- 8.4 and 23.0 +/- 6.3 mmol h-1 l-1, respectively; P < 0.05) and TGc-IAUC (7.9 +/- 5.8 and 4.6 +/- 6.6 mmolh-1 L-1, respectively; P < 0.05). The total group of 81 males was divided into quartiles based on fasting plasma TG, fasting capillary TG, TGc-AUC and TGc-IAUC. Amongst these variables, TGc-AUC was the only significant discriminator of subjects with high homeostasis model assessment (HOMA) (insulin resistance) compared with low HOMA (insulin sensitive). Overall, BMI was the strongest determinant of HOMA. CONCLUSIONS: Diurnal TG profiles can be used to investigate postprandial lipaemia in both lean and mildly obese subjects and may help to detect subjects with an underlying disposition for hypertriglyceridaemia related to insulin resistance, i.e. the metabolic syndrome. 相似文献

Postprandial hyperlipidemia is associated with premature coronary sclerosis in fasting normolipidemic subjects. Self-determined daytime capillary triglyceride (cTG) profiles were compared between 26 fasting normotriglyceridemic patients with premature coronary artery disease (CAD) and 26 controls matched for gender, age and BMI. Daytime triglyceridemia was calculated as total area under the cTG-curve (cTG-AUC). Total and LDL cholesterol were not different between CAD patients (5.4+/-0.8 mmol/l and 3.6+/-0.7 mmol/l, respectively) and controls (5.0+/-0.9 mmol/l and 3.3+/-0.8 mmol/l, respectively). Patients with CAD were characterized by a 44% higher cTG-AUC than matched controls (P<0.01). Using logistic regression analysis, cTG-AUC was the strongest predictor of the presence of CAD (P<0.001). Adding apo AI to the model improved the predictive power from 71 to 77%. Sixteen patients were studied after increasing doses of simvastatin up to 80 mg/day. Although the target for LDL cholesterol was reached by simvastatin 20mg/day, significant effects on cTG-AUC were found only by higher doses of simvastatin. Simvastatin 40 mg/day decreased cTG-AUC by 28% (P<0.05 versus baseline), reaching comparable values as in controls, without further improvement with simvastatin 80 mg/day (26% reduction versus baseline; P<0.05). Daytime triglyceridemia is linked to premature coronary sclerosis in fasting normotriglyceridemic patients. A higher dose of simvastatin was needed to normalize daytime triglyceridemia than was required to "normalize" LDL cholesterol. 相似文献

In order to establish current practice with regard to the reuse of infusion equipment between patients receiving total intravenous anaesthesia (TIVA), a postal survey of 393 consultants was carried out. Additionally, consultants' awareness of relevant guidelines was assessed. Overall, 46% of consultants change all equipment between cases, 37% change one-way valves and 17% change distal lengths of the infusion tubing. Only 13% of consultants reported knowledge of any guidelines. In the absence of any data relevant to the current techniques of administering TIVA, the level of risk associated with the reuse of infusion components is impossible to quantify. Disposal of all equipment between cases incurs a 26% greater cost when compared to changing one-way valves alone. Variation in practice between consultants creates the potential for system errors. Practice should be standardised and, to comply with the published guidelines, should involve disposal of all equipment between cases. 相似文献
