BackgroundAlthough an elevated hemoglobin A1c (HbAc1) level is an independent predictor of worse survival in patients with both digestive cancer and diabetes mellitus, its relationship to short-term prognosis in these patients has not been addressed. This study assessed this relationship in gastrointestinal cancer (GIC) patients with type 2 diabetes mellitus (T2DM).MethodsA retrospective review of patients with GIC with or without T2DM from 2004 to 2014 was performed. Patients with T2DM were grouped according to HbA1c level, either normal (mean < 7.0%) or elevated (mean ≥ 7.0%). Age- and sex-matched GIC patients without T2DM served as controls.ResultsOne hundred and eighteen patients aged 33 - 81 years with T2DM met the study eligibility criteria; 51 were in the normal HbA1c group, and 67 were in the elevated HbA1c group. The 91 patients in the non-T2DM group were randomly selected and matched to the T2DM group in terms of admittance date, age, and sex. There was a trend toward a higher 180-day mortality rate in the T2DM group compared with the non-T2DM group (15.3% vs. 7.7%, P = 0.095) and in the elevated HbA1c group compared with the normal HbA1c group (19.4% vs. 9.8%, P = 0.151); however, the differences were not significant. The duration of the hospital stay was longer in patients with T2DM than in those without T2DM (13.2 vs. 8.9 days, P < 0.05) and in patients with elevated versus normal HbA1c levels (14.5 vs. 11.4 days, P < 0.05). Diabetic GIC patients with elevated HbA1c levels had significantly more total postoperative complications than those with normal HbA1c levels (25.4% vs. 9.8%, P < 0.05). In multivariate regression analyses, short-term adverse outcomes were strongly associated with elevated HbA1c levels (odds ratio (OR): 5.276; 95% confidence level (CI): 1.73 - 16.095; P < 0.05) and no strict antidiabetic treatment (OR: 7.65; 95% CI: 2.49 - 23.54; P < 0.001).ConclusionAn elevated level of HbA1c significantly correlated with and was an independent predictor of short-term adverse outcomes in GIC patients with T2DM.

Background. Extensive preclinical evidence suggests that induced hypothermia can protect tissues from ischemiareperfusion injury, reduce organ damage, and improve survival in the advanced stages of shock. Objectives. We assessed the effects of induced hypothermia on the hemodynamic parameters and coagulation capacity during hemorrhagic shock (HS) and fluid resuscitation, in a pig model of HS with multiple intestinal perforations. Material and Methods. Pigs (n = 16) were randomized into 2 groups: a hypothermia (HT) group (n = 8, 34°C) and a normothermia (NT) group (n = 8, 38°C). Hypothermia to 34°C was induced with a cold blanket at the pre-hospital stage. Traumatic HS shock was induced using multiple intestinal perforations. Pulse indicator continuous cardiac output (PiCCO) was used to monitor hemodynamic changes. Coagulation capacity was measured using thromboelastography (TEG) at baseline as well as during resuscitation periods. Survival was documented for 72 h post-trauma. Results. Mortality in the hypothermic HS group was low, but there were no significant differences in mortality between the groups (mortality = 2/8 HT vs. 5/8 NT, p = 0.137). During hypothermia, the heart rate, extravascular lung water index (EVLWI), oxygen uptake index (VO2), and oxygen delivery index (DO2) in the HT group were significantly lower than those in the NT group. There were no significant differences between the 2 groups in the other hemodynamic indices or prothrombin time. Analyses of thromboelastometry at 34°C during hypothermia showed significant differences for reaction time (R) and alpha angle, but not for maximal amplitude (MA). Conclusions. Rewarming reversed the coagulation changes induced by hypothermia. Induced mild hypothermia (34°C) in the pre-hospital stage affects hemodynamic parameters and the coagulation system but does not worsen outcomes in a pig HS model. The hypothermia-induced coagulation changes were reversed during rewarming without evidence of harmful effects. Our results suggest that pre-hospital induced hypothermia can be performed carefully following major trauma (Adv Clin Exp Med 2015, 24, 4, 571-578).
