Introduction: Both body mass index (BMI) and waist circumference (WC) are associated with diabetes risk, and the difference between them in predictive ability for diabetes is still contentious. We conducted a population-based study to investigate and compare the association of them with diabetes by sex. Methods: This study included a total of 4754 subjects aged 40-80 years with no diabetes at baseline between 2008 and 2017. Using multivariate Cox proportional hazards models, we calculated hazard ratios for diabetes according to tertiles of BMI or WC. Harrell's C statistics was applied to assess and compare the predictive ability of the models using BMI and WC. Results: Both BMI and WC showed the significant positive trends with diabetes risk. In men, the extreme tertiles (BMI [ 25.1 kg/m 2 and WC [ 88.0 cm) provided 1.58-fold or 2.04-fold higher risk compared with the first tertiles (\ 22.6 kg/m 2 and \ 81.2 cm). In women, BMI [ 24.4 kg/m 2 showed 3.28-fold higher risk than the first tertile (\ 21.6 kg/m 2 ), whereas WC C 78.2 cm was more than twice as likely to suffer from diabetes as WC \ 78.2 cm. BMI and WC showed a comparative performance in predicting diabetes in both sexes (P value 0.447 in men, and 0.337 in women).

This retrospective study was aimed to investigate the association between preoperative left ventricular (LV) cardiac function and the incidence of postoperative pulmonary edema (PE) in patients undergoing carotid endarterectomy (CEA). Most patients undergoing CEA for carotid artery stenosis have concomitant heart diseases, leading to hemodynamic instability that can cause postoperative cardiac complications such as cardiac heart failure. LV diastolic function has recently been recognized as an independent predictor of adverse cardiac events in patients undergoing cardiovascular surgery. We analyzed clinical data from the anesthetic and medical records of 149 consecutive patients who underwent CEA at our university hospital between March 2012 and March 2018. LV systolic and diastolic function were evaluated by ejection fraction and the ratio of LV early diastolic filling velocity to the peak velocity of mitral medial annulus ( E / e′ ). Postoperative PE was diagnosed based on chest X-ray and arterial gas analysis by two independent physicians. Postoperative PE was developed in four patients (2.8%). Patients with postoperative PE were not related to preoperative low ventricular ejection fraction, but had a significantly higher E / e′ ratio than those without PE ( P = 0.01). Furthermore, there was an increasing trend of PE according to the E / e′ category. Preoperative LV diastolic function evaluated by E / e′ was associated with the development of postoperative PE in patients who underwent CEA. The results suggest that the evaluation of LV diastolic dysfunction could be possibly useful to predict PE in patients undergoing CEA.

Patient: Male, 72Final Diagnosis: Spinal epidural hematomaSymptoms: ParalysisMedication: HeparinClinical Procedure: LaminectomySpecialty: AnesthesiologyObjective:Rare diseaseBackground:It is still challenging to remove an epidural catheter in a postoperative patient receiving urgent antiplatelet and anticoagulation therapy for acute coronary syndrome.Case Report:While under general anesthesia combined with thoracic epidural anesthesia, a 72-year-old male patient underwent right radical nephrectomy for renal cell carcinoma. On postoperative day 1 (POD1), the patient experienced bradycardia and a decrease in blood pressure, and he was diagnosed acute myocardial infarction. Intraaortic balloon pumping (IABP) was induced for cardiogenic shock, and urgent thrombus aspiration and coronary balloon angioplasty were performed. On POD3, the surgeon removed the epidural catheter under both anti-platelet and anticoagulation therapy. At that time, the platelet count was 45×109/L and the activated partial thromboplastin time (APTT) was 72.2 seconds. Four hours after the epidural catheter was removed, the patient complained of bilateral fatigue in legs and developed a loss of sensation. Six hours after the epidural catheter was removed, he developed motor paralysis and became completely paralyzed in both limbs after 9 hours. At 19 hours after the epidural catheter was removed, emergency magnetic resonance imaging detected a spinal epidural hematoma at the level of Th9-11 with compression of the spinal cord. Emergency laminectomy was performed to decompress and remove the spinal epidural hematoma at 18 hours after the onset of sensorimotor symptoms. After surgery and rehabilitation, these symptoms had only slightly improved.Conclusions:In patients with urgent antithrombotic therapy for urgent percutaneous coronary intervention (PCI) with an IABP for acute coronary syndrome, the epidural catheter should not be removed until the IABP and heparin are discontinued, and platelet counts have recovered.
