PURPOSE: To evaluate the accuracy of different parameters in predicting early (one-month) mortality of patients submitted to orthotopic liver transplantation (OLT). METHODS: This is a retrospective study of forty-four patients (38 males and 10 females, mean age of 52.2 ± 8.9 years) admitted to the Intensive Care Unit of a tertiary hospital. Serial lactate blood levels, APACHE II, MELD post-OLT, creatinine, bilirubin and INR parameters were analyzed by receiver-operator characteristic (ROC) curves as evidenced by the area under the curve (AUC). The level of significance was set at 0.05. RESULTS: The mortality of OLT patients within one month was 17.3%. Differences in blood lactate levels became statistically significant between survivors and nonsurvivors at the end of the surgery (p<0.05). The AUC was 0.726 (95%CI = 0.593-0.835) for APACHE II (p = 0.02); 0.770 (95%CI = 0.596-0.849) for blood lactate levels (L7-L8) (p = 0.03); 0.814 (95%CI = 0.690-0.904) for MELD post-OLT (p < 0.01); 0.550 (95%CI = 0.414-0.651) for creatinine (p = 0.64); 0.705 (95%CI = 0.571-0.818) for bilirubin (p = 0.05) and 0.774 (95%CI = 0.654-0.873) for INR (p = 0.02). CONCLUSION: Among the studied parameters, MELD post-OLT was more effective in predicting early mortality after OLT.

Metformin (MET) is the first-line drug for treating type 2 diabetes mellitus (T2DM). However, MET increases blood lactate levels in patients with T2DM. Lactate possesses proinflammatory properties and causes insulin resistance (IR). Oxamate (OXA), a lactate dehydrogenase inhibitor, can decrease tissue lactate production and blood lactate levels. This study was conducted to examine the effects of the combination of OXA and MET on inflammation, and IR in diabetic db/db mice. Supplementation of OXA to MET led to lowered tissue lactate production and serum lactate levels compared to MET alone, accompanied with further decreased tissue and blood levels of pro-inflammatory cytokines, along with better insulin sensitivity, beta-cell mass, and glycemic control in diabetic db/db mice. These results show that OXA enhances the anti-inflammatory and insulin-sensitizing effects of MET through the inhibition of tissue lactate production in db/db mice.

Abstract The blood lactate level is used to guide the management of trauma patients with circulatory disturbance. We hypothesized that blood lactate levels at the scene (Lac scene) could improve the prediction for immediate interventions for hemorrhage. We prospectively measured blood lactate levels and assessed retrospectively in 435 trauma patients both at the scene and on arrival at the emergency room (ER) of a level I trauma center. Primary outcome was immediate intervention for hemorrhage defined as surgical/radiological intervention and/or blood transfusion within 24 h. Physiological variables plus Lac scene significantly increased the predictive value for immediate intervention (area under the curve [AUC] 0.882, 95% confidence interval [CI] 0.839–0.925) compared to that using physiological variables only (AUC 0.837, 95% CI 0.787–0.887, P = 0.0073), replicated in the validation cohort (n = 85). There was no significant improvement in predicting value of physiological variables plus Lac scene for massive transfusion compared to physiological variables (AUC 0.903 vs 0.895, P = 0.32). The increased blood lactate level per minute from scene to ER was associated with increased probability for immediate intervention (P < 0.0001). Both adding Lac scene to physiological variables and the temporal elevation of blood lactate levels from scene to ER could improve the prediction of the immediate intervention.

AbstractNeuromuscular electrical stimulation has been used to treat cardiovascular diseases and other types of muscular dysfunction. A novel whole-body neuromuscular electrical stimulation (WB-NMES) wearable device may be beneficial when combined with voluntary exercises. This study aimed to investigate the safety and effects of the WB-NMES on hemodynamics, arrhythmia, and sublingual microcirculation. The study included 19 healthy Japanese volunteers, aged 22–33 years, who were not using any medication. Electrocardiogram (ECG), echocardiography, and blood sampling were conducted before a 20-min WB-NMES session and at 0 and 10 min after termination of WB-NMES. Their tolerable maximum intensity was recorded using numeric rating scale. Arrhythmia was not detected during neuromuscular electrical stimulation or during 10 min of recovery. Blood pressure, heart rate, left ventricular ejection fraction, and diastolic function remained unchanged; however, mild mitral regurgitation was transiently observed during WB-NMES in a single male participant. A decrease in blood glucose and an increase in blood lactate levels were observed, but no changes in blood fluidity, sublingual microcirculation, blood levels of noradrenaline, or oxidative stress were shown. WB-NMES is safe and effective for decreasing blood glucose and increasing blood lactate levels without changing the blood fluidity or microcirculation in healthy people.

Background Sepsis is a major health problem in children and aleading cause of death. In recent decades, lactate has been studiedas a biomarker for sepsis, and as an indicator of global tissuehypoxia, increased glycolysis, endotoxin effect, and anaerobicmetabolism. Many studies h ave shown both high levels andincreased serial blood lactate level measurements to be associatedwith increased risk of sepsis mortality.Objective To evaluate serial blood lactate levels as a prognosticfactor for sepsis mortality.Methods We performed an observational, prospective study in thePediatric Intensive Care Unit (PICU) at DR. Sardjito Hospital,Yogyakarta from July to November 2012. We collected serialblood lactate specimens of children with sepsis, first at the time ofadmission, followed by 6 and 24 hours later. The outcome measurewas mortality at the end ofintensive care. Relative risks and 95%confidence intervals of the factors associated with mortality werecalculated using univariate and multivariate analyses.Results Sepsis was found in 91 (50.3%) patients admitted tothe PIW , of whom 75 were included in this study. Five patients(6. 7%) died before the 24-hour lactate collection and 39 patients(52.0%) died during the study. Blood lactate levels of ~ 4mmol;Lat the first and 24-hour specimens were associated with mortality(RR 2.9; 95%CI 1.09 to 7 .66 and RR 4.92; 95%CI 1.77 to 13.65,respectively). Lactate clearance of less than 10% at 24 hours(adjusted RR 5.3; 95% CI 1.1 to 24.5) had a significantly greaterrisk fo llowed by septic shock (adjusted RR 1.54; 95%CI 1.36 to6.4 7) due to mortality.Conclusion In children with sepsis there is a greater risk of mortalityin those with increasing or persistently high serial blood lactatelevels, as shown by less than 10% lactate clearance at 24-hours afterPIW admission.

Purpose: To investigate the acute exercise effects of dynamic standing exercise on blood glucose and blood lactate among children and adolescents with cerebral palsy who are nonambulant. Methods: Twenty-four participants with cerebral palsy who are nonambulant performed 30 minutes of dynamic standing exercise using a motorized device enabling assisted passive movements in an upright weight-bearing position. Capillary blood samples were taken from the fingertip for measurement of blood glucose and blood lactate at rest and at the end of exercise. Results: At rest, the participants had hyperlactatemia that was unaffected after exercise, presented as median and interquartile range at rest 1.8 (1.3:2.7) mmol/L, and after exercise 2.0 (1.1:2.5) mmol/L. Children and adolescents with Gross Motor Function Classification System, level V, had higher lactate levels at rest (2.5 [1.8:2.9] vs 1.4 [1.0:2.0]; P = .030) and after exercise (2.3 [2.0:2.6] vs 1.2 [0.9:2.2]; P = .032) compared with children and adolescents with Gross Motor Function Classification System, level IV, respectively. A statistically significant larger decrease in blood lactate levels after exercise was observed in children and adolescents with higher resting blood lactate levels (ρ = .56; P = .004). There were no statistically significant changes in blood glucose. Conclusions: Forty percentage of the participants had mild hyperlactatemia at rest and participants with the highest blood lactate levels at rest had the greatest decrease in blood lactate levels after one bout of exercise. Children and adolescents who were classified with the highest level of the Gross Motor Function Classification Scale had higher blood lactate levels. More studies are needed on how to prevent chronically high resting levels of lactate with exercise in children with cerebral palsy who are nonambulant.
