High-intensity exercise (3000-meter runner) contributes to muscle fatigue. Fatigue can be determined by measuring blood lactate levels. Blood lactate levels are a product of anaerobic metabolism. Lactate accumulation due to anaerobic physical activity can inhibit the glycolytic enzyme that affects decreased ATP production, damage of the calcium and sodium pumps in the muscles and causes fatigue. This study aimed to analyze the effect of vitamin E on the level of fatigue through the response of blood lactate levels in the runner 3000 meters. This research was a quasi-experimental research with a pretest-posttest design. Research subjects were 9 volunteer athletes (3000 meters runners) Aceh province, male, and aged 15-20 years. The treatments were vitamin E at a dose of 1x400 IU per day and administered for 14 days. Blood lactate levels were examined using the method of calorimetry. The statistical analysis was using the homogeneity test of variance (Levene's test), the normality test (Kolmogorov-Smirnov test) and paired t-test with a significant level of 5% (p-value<0.05). The results showed that blood lactate levels decreased approximately 13.93% after vitamin E supplementation. There was no significant difference (p=0.27) between blood lactate levels before and after vitamin E supplementation in athletes. In conclusion, vitamin E supplementation did not significantly lower blood lactate levels therefore vitamin E did not significantly reduce muscle fatigue in men's athletics.

Abstract Background and objectiveIn severe sepsis, increased blood lactate levels are observed indicating impaired oxidative phosphorylation, which secondarily causes hypoxic hypoxia and stagnant tissue hypoxia. Among all other related factors, a high rise of the lactate level in blood may be a useful predictor of sepsis patients' mortality. This study aims to determine the association of consecutive blood lactate levels with the patient's mortality with sepsis admitted in the Critical Care Unit (CCU). MethodsThis prospective study included 50 patient of septicemia at CCU above 18 years in a tertiary care centre. On admission, at 24 hours and 72 hours, blood lactate levels were monitored. Their clinical status was evaluated for 28 days to categorise as survivor and non-survivor. The statistical analysis was made with Microsoft Excel and SPSS version 20. To test the difference in mean blood lactate levels among survivors and non-survivors Student’s t-test was applied. A p-value of less than 0.05 was considered significant. Prior ethical clearance from the institutional ethics committee of human with informed consent from the patients was obtained for data collection.ResultsThe current study included 50 patients of septicemia, 23 were survivors, and 27 were non-survivors after 28 days of follow up. The mean lactate range for the 23 survivors was ranged from 0.43 mmol/l to 5.69 mmol/l, whereas for non-survivors, it was 1.64 mmol/l to 6.14 mmol/l. The mean value of lactate for the survivors and non-survivors during admission, at 24 hours and at 72 hours were 0.9545±0.45798 vs 2.5204±1.51498, 1.2461±1.21360 vs 2.5107±1.63678 and 1.5496±1.66788 vs 2.7904±2.00160. The differences between the mean lactate values between survivors and non-survivors at different time intervals were highly significant.ConclusionA slower rate of lactate clearance during hospitalisation may be a significant factor associated with severe sepsis patient mortality. Thus serial blood lactate levels is a significant predictor of mortality and should be monitored.

PURPOSE: The purpose of this study was to investigate the effects of training on improvement in pulmonary function and swimming performance by implementing static apnea training for 4 weeks in elite male swimmers.METHODS: Twenty elite swimmers were divided into two groups, the apnea training group (Apnea, n=11) and the control group (control, n=9). Each swimmer received identical swimming and ground training for 4 weeks. The apnea group performed 10 sets of breathholding a day additionally. In all participants, the pulmonary function tests [forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1)] were evaluated. The blood lactate level was also measured after each swimmer completed swimming 5 laps.RESULTS: After 4 weeks of static apnea training, the FVC of the apnea group significantly increased (p=.008), whereas the FEV1/FVC ratio did not change. Breath-holding time increased significantly after apnea training (p=.001). There were no significant differences between the groups in the 50-m time trial records. However, the apnea group show a significant difference at the 4th (p=.013) and 5th trial (p=.023). The blood lactate levels after the 50-m trial was not significantly different between the groups, but the levels in the apnea group showed a significant increase in the results of the 2nd trial compared to those before apnea training (p=.008).CONCLUSIONS: The results of our study reveal that static apnea training improves pulmonary function, in contrast to a few time trials that show varying differences in swimming records and blood lactate levels. These results warrant a review of the training protocol to evaluate the effect on performance. In conclusion, static apnea training is a potential exercise that can improve performance in competitive sports.

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: Pelvic pain around the time of mensturation without any identifiable pathologic lesion present from menarche is called primary dysmenorrhea. The pain is believed to be related to prostaglandin (PG). Women with dysmenorrhoea have a relatively high concentration of PGF 2 alpha in menstrual fluid and suppression of PG synthesis has become the main treatment. Aim: To compare mean reduction in pain in patients presenting with primary dysmenorrhea given vitamin E & Mefenamic acid versus Mefenamic acid alone. Results: It was a randomized controlled trial which was conducted in Department of Obstetrics & Gynecology, THQ Raiwind Hospital, Lahore for 6 months duration w.e.f 01/02/2017 to 31/07/2017. In this study, 18(36%) in Vitamin-E group and 21(42%) in Mefenamic acid group were between 15-20 years while 32(64%) in Vitamin-E group and 29(58%) in Mefenamic acid group were between 21-25 years, mean±sd was calculated as 20.86±2.92 and 20.66±2.86 years respectively, mean dysmenorrheal pain at baseline was recorded as 50.06±10.27 in Vitamin-E group and 50.14±10.28 in Mefenamic acid group, p value < 0.754, showing that both groups are insignificant, mean dysmenorrheal pain after treatment was recorded as 20.50±10.04 in Vitamin-E group and 30.22±10.28 in Mefenamic acid group, p value was < 0.002 showing significant difference between the two group, comparison of mean reduction in dysmenorrheal pain after treatment was recorded as 20.56±0.91 in Vitamin-E group and 10.92±0.75 in Mefenamic acid group, p value was < 0.000, showing significant difference. Conclusion: We concluded that there is a significant mean reduction in dysmenorrhic pain in patients given Mefenamic Acid + Vitamen E as compared to patients given Mefenamic Acid alone. Keywords: Dysmenorrhic pain, Mefenamic Acid + Vitamen E, mean reduction in dysmenorrhic pain

Serum vitamin E levels are reduced in newborn infants. It has been reported that this deficiency is responsible, in part, for the development of anemia in premature infants during the first 6 weeks of life. The efficacy of vitamin E supplementation for the prevention of anemia in premature infants has been studied in a randomized, controlled, and blinded trial. Premature infants whose birth weights were less than 1,500 g were given, by gavage, 25 IU of dl-α-tocopherol or a similar volume of the drug vehicle. Treatment was continued for the first 6 weeks of life. A total of 178 infants were studied. Vitamin E levels were significantly higher in a supplemented group by day 3 and for the remainder of the 6-week period. At 6 weeks of age, there was no significant difference between the supplemented and unsupplemented groups in hemoglobin concentration, reticulocyte and platelet counts, or erythrocyte morphology. It is concluded that there is no evidence to support a policy of administering vitamin E to premature infants to prevent the anemia of prematurity.

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.
