    Objectives: The aim of this study was to determine the effects of intraoperative hyperglycemia on postoperative outcomes in orthotopic liver transplant recipients. Materials and Methods: After ethics committee approval was obtained, we retrospectively analyzed the records of patients who underwent orthotopic liver transplant from January 2000 to December 2013. A total 389 orthotopic liver transplants were performed in our center, but patients aged < 15 years (179 patients) were not included in the analyses. Patients were divided into 2 groups based on their maximum intraoperative blood glucose level: group 1 (patients with intraoperative blood glucose level < 200 mg/dL) and group 2 (patients with intraoperative blood glucose level > 200 mg/dL). Postoperative complications between the 2 groups were compared. Results: There were 58 patients (37.6%; group 1, blood glucose < 200 mg/dL) who had controlled blood glucose and 96 patients (62.3%; group 2, blood glucose > 200 mg/dL) who had uncontrolled blood glucose. The mean age and weight for groups 1 and 2 were similar. There were no differences between the 2 groups regarding the duration of anhepatic phase (P=.20), operation time (P=.41), frequency of immediate intraoperative extubation (P=.14), and postoperative duration of mechanical ventilation (P=.06). There were no significant differences in frequency of patients who had postoperative infectious complications, acute kidney injury, or need for hemodialysis. Mortality rates after liver transplant were similar between the 2 groups (P=.81) Conclusions: Intraoperative hyperglycemia during orthotopic liver transplant was not associated with an increased risk of postoperative infection, acute renal failure, or mortality.

    Which Is Responsible for Cardiac Autonomic Dysfunction in Non-Diabetic Patients with Metabolic Syndrome: Prediabetes or the Syndrome Itself
    (2016) Balcioglu, Akif Serhat; Akinci, Sinan; Cicek, Davran; Eldem, Halil Olcay; Coner, Ali; Bal, Ugur Abbas; Muderrisoglu, Haldun; https://orcid.org/0000-0001-5250-5404; https://orcid.org/0000-0002-5711-8873; https://orcid.org/0000-0002-9446-2518; 26610403; AAD-5564-2021; ABD-7321-2021; AAK-4322-2021
    Aims: Cardiac autonomic dysfunction (CAD) is associated with both prediabetes and metabolic syndrome (MS). Heart rate variability (HRV) and heart rate turbulence (HRT) are reliable 24-h Holter-ECG findings of cardiac autonomic function. This study aimed to investigate the relation between MS and its components and CAD using HRV and HRT. Materials and methods: The study included 80 non-diabetic patients with MS and 70 control subjects. All study population and the patients with MS were further analyzed for each diagnostic component of MS to investigate which criteria impaired HRV and HRT. Results: HRV and HRT parameters were disturbed in patients in the MS group. While impairment in HRV and HRT was significantly related to the presence of the fasting plasma glucose (FPG) criterion, there were no differences between groups in terms of the other 4 MS criteria. Moreover, FPG level was significantly correlated with SDNN (r = -0.352, p < 0.001), SDNN index (r = -0.423, p < 0.001), SDANN (r = -0.301, p < 0.001), RMSSD (r = -0.237, p < 0.001), pNN50 (r = -0.237, p < 0.001), turbulence onset (TO) (r = 0.365, p < 0.001) and turbulence slope (TS) (r = -0.365, p < 0.001). Among the MS diagnostic criteria, only FPG level was an independent determinant of all HRV and HRT parameters. Conclusions: This study confirms the relation between MS and CAD. Increased FPG alone appears to be responsible for the mentioned findings among the 5 diagnostic criteria. Accordingly, CAD may be the result of prediabetes, not MS in patients with MS.
