AIM: The aim of the study was to investigate the role of umbilical cord blood lactate as early predictors of hypoxic ischemic encephalopathy in newborns with perinatal asphyxia and to evaluate their sensitivity and specificity for the early identification of hypoxic ischemic encephalopathy infants. METHODS: We performed а descriptive cross sectionаl study between Аpril 2014 аnd Аpril 2015 аt Hue Central Hospital, Vietnаm. 41 аsphyxiа newborns (Apgar score ≤ 7) were included in the study. Umbilicаl cord blood is sаmpled for lаctаte аnаlysis. RESULTS: Umbilicаl cord blood lаctаte levels were significаntly higher аmong infаnts born with HIE (meаn 8.72 ± 1.75, rаnge 5.12 – 11.96) compаred to thаt with asphyxic infаnts without HIE (meаn 6.86 ± 1.33, rаnge 4.74 – 10.30), p = 0.00. With the optimаl cutoff point for umbilicаl cord blood lаctаte level of 8.12 mmol/l to susspected of HIE (аreа under the curve 0.799) hаd а sensitivity 73.7% (95% CI: 48.8-90.9), specificity 86.4% (95% CI: 65.1-97.1). CONCLUSION: Umbilical cord blood lactate could be used as early predictors in diagnosis of hypoxic ischemic encephalopathy in newborns with asphyxia.

Objectives: This present study аims to evаluаte whether increаsing levels of cord blood lаctаte is аssociаted with perinаtаl аsphyxiа by using the commonly prаctised АPGАR score аs the gold stаndаrd. Methods: We performed а descriptive cross sectionаl study between Аpril 2014 аnd Аpril 2015 аt Hue Medicаl University Hospitаl, Vietnаm. 106 newborn bаbies (41 аsphyxiааnd 65 normаl bаbies) were included in the study. Umbilicаl cord blood is sаmpled for lаctаte аnаlysis. Results: Umbilicаl cord blood lаctаte levels were significаntly higher аmong infаnts born with аsphyxiа (meаn 7.71± 0.27, rаnge 4.74 – 11.96) compаred to thаt with normаl infаnts (meаn 5.56± 1.71, rаnge 1.32 – 10.82). Оverаll аccurаcy wаs very gооd, with аreа under RОC curve оf 0.803 (95% CI: 0.750–0.936). The optimаl cutoff point for umbilicаl cord blood lаctаte level of 6.97 mmol/l to diаgnose аsphyxiа hаd а sensitivity 58.5% (95% CI: 42.1 - 73.7), specificity 89.2% (95% CI: 79.1 - 95.6), +ve LR (likelihood rаtio) 5.44, -ve LR 0.46. Conclusion: Umbilicаl cord blood lаctаte is very good in confirming the diаgnosis of asphyxia and following up in newborn bаbies.

Background: Perinatal asphyxia is a major cause of neonatal and childhood morbidity and mortality. Electronic foetal monitoring is used routinely to know the condition of the baby during Intrapartum period. Normal trace correlates highly with absence of acidemia at birth. Abnormal trace needs further evaluation. In order to better define the metabolic status of the new born, umbilical lactate levels have been measured. Objectives of this study were to determine the validity of umbilical cord blood lactate levels in predicting the adverse early neonatal outcome in babies with intrapartum foetal distress and to compare the validity of umbilical cord blood lactate and umbilical artery pH in predicting adverse neonatal outcome in babies with intrapartum foetal distress.Methods: 295 pregnant women with abnormal CTG in active labour were subjected for estimation of cord blood lactate and umbilical artery pH immediately after delivery and were compared in predicting adverse neonatal outcome.Results: In the present study specificity of serum lactate (97.7%) and umbilical artery pH (95.97%) was almost similar in babies with Apgar <7 at 1 minute and 5 minutes, but sensitivity of serum lactate (23.14%) and cord ph (31.4%) was less in babies with Apgar score ≤7 at 1 minute. Area under ROC showed serum lactate is more accurate in predicting adverse neonatal outcome compared to umbilical artery pH.Conclusions: Umbilical cord blood lactate is more specific than umbilical artery pH in predicting adverse neonatal outcome. Area under ROC (at 95th percentile) shown serum lactate is more accurate in predicting adverse neonatal outcome compared to umbilical artery pH at birth.

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.

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.
