Blood Glucose Concentrations

Abstract Neonatal hypoglycemia (NH) is one of the most common abnormalities encountered in the newborn. Maintaining glucose homeostasis is one of the important physiological events during fetal-to-neonatal transition. Transient low blood glucose concentrations are frequently encountered in the majority of healthy newborns and are the reflections of normal metabolic adaptation processes. Nevertheless, there is a great concern that prolonged or recurrent low blood glucose levels may result in long-term neurological and developmental consequences. Strikingly, it was demonstrated that the incidence and timing of low glucose concentrations in the groups most at risk for asymptomatic neonatal hypoglycemia, did not find association between repetitive low glucose concentrations and poor neurodevelopmental outcomes. On the contrary, NH due to hyperinsulinism is strongly associated with brain injury. Fundamental issue of great professional controversy is concerning the best manner to manage asymptomatic newborns NH. Both, overtreating NH and undertreating NH are poles with significant potential disadvantages. Therefore, NH is one of the most important issues in the day-to-day practice. This article appraises the critical questions of definition (widely accepted blood glucose concentration: < 2.6 mmol/l or 47 mg/dl), follow-up ad management of NH.

Blood Glucose Concentrations

Experimental data suggest that postischemic blood glucose concentration plays an important role in modulating both ischemic cerebral infarction and selective neuronal necrosis. This study investigated the association between functional neurological recovery and blood glucose concentrations in human cardiac arrest survivors. A group of 145 nondiabetic patients were evaluated after witnessed ventricular fibrillation cardiac arrest. Data regarding cardiac arrest were collected according to an internationally accepted protocol immediately after arrival. Blood glucose was measured on admission and 6, 12, and 24 h thereafter. To control for duration of cardiac arrest and cardiogenic shock, both known to influence outcome as well as blood glucose, levels, Spearman rank partial correlation was used. In this multivariate analysis, a high admission blood glucose level tended to be associated with poor neurological outcome ( rs = −0.16, n = 142, p = 0.06). The association between high median blood glucose levels over 24 h and poor neurological outcome was strong and statistically significant ( rs = −0.2, n = 145, p = 0.015). High blood glucose concentrations occurring over the first 24 h after cardiac arrest have deleterious effects on functional neurological recovery. Whether cardiac arrest survivors might benefit from reduction of blood glucose levels needs further investigation.

The Impact

Ingesting quality carbohydrates has been shown to be essential for dancers. Given that most dance classes take place in the morning, it has been recommended that dancers eat a well-balanced breakfast containing carbohydrates, fats, and protein as a means of fueling this activity. The aim of this study was to determine the effect of a moderate glycemic index energy (MGI) bar or a fasting condition on dancers’ blood glucose levels and perceived pleasure-displeasure response during the first dance class of the day. In a randomized counterbalanced design, 10 female preprofessional dance students took their regular scheduled contemporary dance class, on four separate occasions. On each occasion, they consumed either a commercially prepared carbohydrate (CHO)-dense energy bar (47.3 g CHO) or water (FAST). Plasma glucose responses and pleasure-displeasure affect were measured before and at two time points during the class. Dancers who consumed the MGI bar had significantly greater peak blood glucose levels at all time points than those who fasted (p<0.05). Regarding affective state measures, participants who had breakfast had significantly greater pleasure scores than those who only ingested water (p<0.05). In conclusion, results suggest that CHO with an MGI value positively impacts blood glucose concentrations during a dance class. Further, we conclude that skipping breakfast can have an unfavorable effect on the pleasure-displeasure state of dancers. These findings highlight the impact of breakfast on how one feels, as well as the physiological and metabolic benefits of CHO as an exogenous energy source in dancers.

Carbohydrate Supplement

Numerous studies have shown that ingesting carbohydrate in the form of a drink can improve exercise performance by maintaining blood glucose levels and sparing endogenous glycogen stores. The effectiveness of carbohydrate gels or jellybeans in improving endurance performance has not been examined. On 4 separate days and 1–2 hr after a standardized meal, 16 male (8; 35.8 ± 2.5 yr) and female (8; 32.4 ± 2.4 yr) athletes cycled at 75% VO2peak for 80 min followed by a 10-km time trial. Participants consumed isocaloric (0.6 g of carbohydrate per kg per hour) amounts of randomly assigned sports beans, sports drink, gel, or water only, before, during, and after exercise. Blood glucose concentrations were similar at rest between treatments and decreased significantly during exercise with the water trial only. Blood glucose concentrations for all carbohydrate supplements were significantly, p < .05, higher than water during the 80-min exercise bout and during the time trial (5.7 ± 0.2 mmol/L for sports beans, 5.6 ± 0.2 mmol/L for sports drink, 5.7 ± 0.3 mmol/L for gel, and 4.6 ± 0.3 mmol/L for water). There were no significant differences in blood glucose between carbohydrate treatments. The 10-km time trials using all 3 carbohydrate treatments were significantly faster (17.2 ± 0.6 min for sports beans, 17.3 ± 0.6 min for sports drink, and 17.3 ± 0.6 min for gel) than water (17.8 ± 0.7 min). All carbohydrate-supplement types were equally effective in maintaining blood glucose levels during exercise and improving exercise performance compared with water only.

Objectives The objective of this study was to determine if hypoglycemia is an effect of overnight fasting and gonadectomy in kittens, as well as to determine predictors of baseline and postoperative blood glucose. Methods This was a prospective observational study. Seventy-five kittens between the age of 8 and 16 weeks undergoing routine castration or ovariohysterectomy at an animal shelter were included. Two blood glucose measurements were analyzed per kitten after an overnight fast: a baseline reading prior to preoperative examination, and a reading immediately postoperatively. Predictors of the baseline and postoperative blood glucose levels were determined using multi-level mixed-effects linear regression. Results Kittens, when fasted overnight, were not hypoglycemic (<60 mg/dl). No kittens exhibited clinical signs consistent with hypoglycemia. No kittens had a blood glucose <70 mg/dl postoperatively. Postoperative hyperglycemia (>150 mg/dl) was observed in 44% of kittens. The only predictor of fasted blood glucose levels was body condition score. The only predictor of postoperative blood glucose levels was the fasting blood glucose value. Conclusions and relevance Overnight fasting prior to elective sterilization in 8- to 16-week-old kittens did not result in hypoglycemia. Concern regarding hypoglycemia after a prolonged fast in kittens may be unwarranted for short procedures in healthy animals.

Aim This study investigated whether kisspeptin-10 (KP-10) prevents diabetic rhesus monkeys from insulin-induced hypoglycemic shock. Materials and methods Thirty-six adult male rhesus monkeys were used, six in each group. Diabetes was induced with streptozotocin (45 mg/kg b.w.; single dose i.v.). Groups were as: saline control, insulin alone, pre-insulin (treated with KP-10, 30 min before insulin), post-insulin (treated with KP-10, 30 min after insulin), treated with premix dose of KP-10 (50 μg) and insulin, and the group treated with the kisspeptin antagonist P234 (50 μg). Following an overnight fast, each animal was subjected to respective treatment, and blood glucose concentrations were recorded every 30-min interval for 3 h. Results Intergroup comparisons demonstrated that treatment with KP-10 prior to insulin administration and kisspeptin–insulin premix treatment allowed blood glucose levels to rise to significantly higher levels (p < 0.001) by 180 min in diabetic and healthy animals compared to treatment with insulin alone. However, intragroup comparisons revealed a significant decrease in blood glucose level in diabetic animals only. Treatment with P234 antagonist followed by insulin administration abolished the preventive action of kisspeptin, whereby blood glucose decreased significantly (p < 0.001) in both diabetic and healthy animals. KP-10 post-insulin treatment, however, remained ineffective and led, instead, to significantly decreased glucose concentrations by 180 min in both diabetic and healthy animals when compared to animals treated with insulin alone. Conclusions KP-10 bears therapeutic potential to prevent hypoglycemic shock that may sometimes occur during intensive insulin therapy. Several pharmacological aspects of its interaction with insulin and other drugs, however, remain to be investigated.

In Indonesia, it is estimated that there would be increasing in number of diabetes mellitus patients become 12 million cases in 2030. The expensive cost of conventional medications motivates people to find alternative medication. Bentonite is a natural clay which is a good absorbent and frequently called as healing clay for its potency in body detoxification. This study is an experimental research to prove bentonite which is a good absorbent and adsorbent in decreasing blood glucose concentration in diabetes mellitus. Subject of this research is 20 female Wistar rats which weigh 150–250 g. These subjects were divided into two groups: control group and bentonite group. Diabetes is induced by alloxan monohydrate 150mg/kg intraperitoneally, causing β cell necrosis in pancreas. Result of independent t-test showed that bentonite could significantly lower blood glucose levels with average value of 131.30 mg/dL (p=0.010). This concludes that bentonite canreduce blood glucose level in diabetic-induced rats.

Background: Hypoglycemia is the most common event of failure of metabolic adjustments in the newborn. Changes in maternal and fetal monitoring techniques, administration of glucose-containing solutions during labor, delivery and early feeding in neonates significantly alter blood glucose concentrations during the first week of postnatal life. Subjects and Methods: A total of 90 healthy (60 born by FTND, 30 born by LSCS) term, AGA infants were longitudinally evaluated at birth, at one hour after feeds (post feed), and after 6 hours of life. Plasma glucose was estimated from Heel Prick capillary samples by glucometer method. The influence of mode of delivery, the interval between feeds, sex, birth weight, on blood glucose was analyzed. Results: The way of delivery did not affect the plasma glucose concentration in neonates. There was a substantial increase in blood glucose concentration after the first feed irrespective of their birth weight. It was found that female babies had a higher blood glucose concentration than male babies during our study period. All babies maintained normal blood glucose with the continuation of breastfeeding. Conclusion: Plasma glucose levels are satisfactorily maintained in healthy term infants without resort to pre-lacteal feeds and mode of delivery did not influence plasma glucose. There is no need to check blood glucose levels routinely in an asymptomatic, healthy, term, breastfed infants.

Metabolic Properties

The endocrine stress response helps to maintain homeostasis at times of increased demand and supports survival through energy mobilization. Paradoxically, low blood glucose levels impede the endocrine stress response, yet increasing blood glucose levels through sugar consumption prior to stress restores it. This suggests that glucose availability may play a causal role in the endocrine stress response. However, sugar has other distinct properties beyond the raise of blood glucose concentration. Here, we investigated the potential role of sweetness in restoring the cortisol stress reactivity after fasting. N=152 women (mean(age)=21.53, sd(age)=2.61) participated in a psychosocial stress test for groups in the morning after an overnight fast. Prior to stress induction, participants either consumed a drink that contained a caloric sweetener (sugar, n=51), an equally sweet drink containing non-caloric sweetener (sweetener, n=46), or water (n=56). Salivary cortisol and blood glucose levels were assessed repeatedly. Former studies suggested that sugar load prior to stress leads to increased cortisol responses compared to water, and sweetener. The effects of the consumed drinks on cortisol trajectories were tested using multilevel mixed models. Unexpectedly, we found that sugar and sweetener each significantly increased cortisol stress reactivity compared to water. Indeed, sweetener lead to cortisol increases comparable to sugar. Changes in blood glucose levels after drink consumption were not significantly associated with stress-induced increases in cortisol. This suggests that not the metabolic properties of sugar, but properties of sweet taste prior to stress are critical to boost the endocrine stress response to stress.

According to the literature, uncontrolled glycemia can be a strong predictor of severe morbidity and mortality in different types of viral infections. Hyperglycemia can make the condition worse in diabetic and nondiabetic patients infected with sever acute respiratory syndrome 2 (SARS-CoV-2). Therefore, maintaining blood glucose levels low (within the safe range of 70-100 mg/ mg/dl) seems to be beneficial in our battle against Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2.

Glucose cycling (GC) is increased in pancreatic islets from hyperglycemic 6-mo-old ob/ob mice. We determined whether normalization of glycemia alters islet GC and insulin release in response to glucose as well as oxidation and utilization of the glucose. Mice were treated with phlorizin in dimethyl sulfoxide (DMSO) for 10 days, which resulted in normalization of blood glucose concentrations. Controls received DMSO. The mice were fasted overnight and killed, and their islets were isolated for measurements of insulin release at 5.5 and 16.7 mM glucose and at 16.7 mM glucose plus 10 mM arginine. GC was measured by the incorporation of 3H from 3H2O into carbon 2 of glucose, glucose oxidation by the yield of 14CO2 from [U-14C]glucose, and glucose utilization by the yield of 3H2O from [5-3H]glucose. Phlorizin treatment did not alter the response of insulin to glucose and to glucose plus arginine. GC was 30% in control and phlorizin-treated animals. Glucose oxidation and utilization were also the same in both groups. In fed 10- to 12-mo-old mice exhibiting a broad range of blood glucose levels, there was no correlation between GC and either insulin release or glucose concentrations. Thus the islets of ob/ob mice exhibit an increased rate of GC regardless of glycemia. This indicates that the increased rate of GC is an important characteristic of the diabetic syndrome in these animals and not simply secondary to hyperglycemia.
