  3. High activity enables life on a high-sugar diet: blood glucose regulation in nectar-feeding bats.

    2011-12-01

    High blood glucose levels caused by excessive sugar consumption are detrimental to mammalian health and life expectancy. Despite consuming vast quantities of sugar-rich floral nectar, nectar-feeding bats are long-lived, provoking the question of how they regulate blood glucose. We investigated blood glucose levels in nectar-feeding bats (Glossophaga soricina) in experiments in which we varied the amount of dietary sugar or flight time. Blood glucose levels increased with the quantity of glucose ingested and exceeded 25 mmol l(-1) blood in resting bats, which is among the highest values ever recorded in mammals fed sugar quantities similar to their natural diet. During normal feeding, blood glucose values decreased with increasing flight time, but only fell to expected values when bats spent 75 per cent of their time airborne. Either nectar-feeding bats have evolved mechanisms to avoid negative health effects of hyperglycaemia, or high activity is key to balancing blood glucose levels during foraging. We suggest that the coevolutionary specialization of bats towards a nectar diet was supported by the high activity and elevated metabolic rates of these bats. High activity may have conferred benefits to the bats in terms of behavioural interactions and foraging success, and is simultaneously likely to have increased their efficiency as plant pollinators.

    Full Text Available The purpose of this study was to establish a mathematical model which can be used to estimate glucose levels in the blood over time. The equations governing this process were manipulated with the use of techniques such as separation of variables and integration of first order differential equations, which resulted in a function that described the glucose concentration in terms of time. This function was then plotted, which allowed us to find when glucose concentration was at its highest. The model was then used to analyze two cases where the maximum glucose level could not exceed a certain level while the amount of carbohydrates and glycemic index were varied, independently.

  5. Blood glucose in acute stroke

    Olsen, Tom Skyhøj

    2009-01-01

    Blood glucose is often elevated in acute stroke, and higher admission glucose levels are associated with larger lesions, greater mortality and poorer functional outcome. In patients treated with thrombolysis, hyperglycemia is associated with an increased risk of hemorrhagic transformation...... of infarcts. For a number of years, tight glycemic control has been regarded as beneficial in critically illness, but recent research has been unable to support this notion. The only completed randomized study on glucose-lowering therapy in stroke has failed to demonstrate effect, and concerns relating...... to the risk of inducing potentially harmful hypoglycemia has been raised. Still, basic and observational research is overwhelmingly in support of a causal relationship between blood glucose and stroke outcome and further research on glucose-lowering therapy in acute stroke is highly warranted....

  6. High prevalence of abnormal circadian blood pressure regulation and impaired glucose tolerance in adults with hypopituitarism.

    Patients with hypopituitarism have an increased mortality from cardiovascular events. Reduced nocturnal blood pressure decline (non-dipping) and impaired glucose tolerance are considered as cardiovascular risk factors. To evaluate the role of these risk factors in patients with hypopituitarism we determined the 24-hour blood pressure regulation and glucose tolerance status in hypopituitary patients with and without growth hormone (GH) deficiency. Sixty-one hypopituitary subjects 5 +/- 3 years after brain surgery because of macroadenoma, 61 patients with type 2 diabetes mellitus (T2DM), and 20 healthy controls were included. Forty-four hypopituitary patients were GH deficient and 28 of these on GH treatment. Non-dipping was observed in 41 % (n = 7) of hypopituitary subjects with normal GH release, in 46 % (n = 13) of patients on GH therapy, and in 69 % (n = 11) of untreated GH deficient patients. Untreated GH deficient patients had a higher systolic night/day ratio (1.00 +/- 0.03) compared to non GH deficient (0.92 +/- 0.02; p < 0.02) and GH treated hypopituitary patients (0.93 +/- 0.01; p < 0.02). The rate of non-dipping in hypopituitarism was comparable to that in T2DM. Pathologic glucose tolerance was diagnosed in 30 % of the hypopituitary patients. The prevalence of non-dipping was independent of glucose metabolism in hypopituitary patients. All controls had normal night time blood pressure fall and glucose metabolism. The high prevalence of nocturnal non-dipping and glucose intolerance detected in this cohort might contribute to the increased cardiovascular risk of hypopituitary patients.

  7. The impact of high-dose vitamin C on blood glucose testing in ¹⁸F-FDG PET imaging.

    Complementary and alternative therapies in addition to standard oncology protocols are commonly sought by cancer patients; however, few patients disclose their complementary treatments to their cancer care team. A lack of communication may result in unforeseen side effects and the potential for some alternative therapies to interfere with or inhibit conventional treatment. High-dose vitamin C therapy, in particular, may lead to an inability to measure a patient's blood glucose level before (18)F-FDG injection for PET/CT scanning. We report a case of a 52-y-old woman referred for (18)F-FDG PET/CT to evaluate the extent of recurrent colorectal cancer. The PET/CT scan immediately followed a single intravenous dose of 25 g of ascorbic acid from her naturopath. A glucometer that applies the glucose oxidase method for measuring fasting blood glucose was used, for which high doses of vitamin C are listed as a contraindication. The high concentration of ascorbic acid in the patient's blood sample interfered with the chemical reaction on the glucose strip, and therefore no blood glucose measurement could be attained. With more patients receiving alternative and complementary cancer therapies, it is important to know what the implications of orthomolecular therapy might be on routine blood glucose testing for (18)F-FDG PET scans. (18)F-FDG is in direct competition with glucose; therefore, elevated blood glucose levels will cause a decrease in (18)F-FDG absorption and may lead to a false-negative scan.

  8. The impact of brief high-intensity exercise on blood glucose levels

    Full Text Available O Peter AdamsFaculty of Medical Sciences, the University of the West Indies, Cave Hill Campus, St Michael, BarbadosBackground: Moderate-intensity exercise improves blood glucose (BG, but most people fail to achieve the required exercise volume. High-intensity exercise (HIE protocols vary. Maximal cycle ergometer sprint interval training typically requires only 2.5 minutes of HIE and a total training time commitment (including rest and warm up of 25 minutes per session. The effect of brief high-intensity exercise on blood glucose levels of people with and without diabetes is reviewed.Methods: HIE (≥80% maximal oxygen uptake, VO2max studies with ≤15 minutes HIE per session were reviewed.Results: Six studies of nondiabetics (51 males, 14 females requiring 7.5 to 20 minutes/week of HIE are reviewed. Two weeks of sprint interval training increased insulin sensitivity up to 3 days postintervention. Twelve weeks near maximal interval running (total exercise time 40 minutes/week improved BG to a similar extent as running at 65% VO2max for 150 minutes/week. Eight studies of diabetics (41 type 1 and 22 type 2 subjects were reviewed. Six were of a single exercise session with 44 seconds to 13 minutes of HIE, and the others were 2 and 7 weeks duration with 20 and 2 minutes/week HIE, respectively. With type 1 and 2 diabetes, BG was generally higher during and up to 2 hours after HIE compared to controls. With type 1 diabetics, BG decreased from midnight to 6 AM following HIE the previous morning. With type 2 diabetes, a single session improved postprandial BG for 24 hours, while a 2-week program reduced the average BG by 13% at 48 to 72 hours after exercise and also increased GLUT4 by 369%.Conclusion: Very brief HIE improves BG 1 to 3 days postexercise in both diabetics and nondiabetics. HIE is unlikely to cause hypoglycemia during and immediately after exercise. Larger and longer randomized studies are needed to determine the safety, acceptability, long

    Full Text Available The level of glucose in the blood can be measured by applying a drop of blood to a chemically treated, disposable ‘test-strip’, which is then inserted into an electronic blood glucose meter. The reaction between the test strip and the blood is detected by the meter and displayed in units of mg/dL or mmol/L. There are a number of different types of meters available, and all are slightly different. Take care when applying the general principles described in this article to the specific glucose meter you are using.

  10. High glucose induces the expression of osteopontin in blood vessels in vitro and in vivo.

    Osteopontin (OPN) is involved in mineral metabolism and the inflammatory response while diabetes mellitus is associated with severe and extensive vascular calcification. Therefore, we speculated that OPN could be a key factor in the calcification and dysfunction of blood vessels exposed to high glucose. To identify the relationship between high glucose and OPN, we used high glucose medium to stimulate smooth muscle cells (SMCs) and vascular endothelial cells (VECs) in vitro and diabetic rats for in vivo analyses. As assessed by flow cytometry and western blots, SMC and VEC apoptosis levels increased with high glucose. Potassium and calcium uptake by cells were also increased with high glucose. These findings demonstrated the relationship between mineral metabolism and high glucose. Western blot and quantitative real time polymerase chain reaction analyses demonstrated that OPN increased in vitro with high glucose stimulation. The inflammatory factor ICAM1 and the inhibitory phosphorylation of endothelial nitric-oxide synthase (eNOS) (Thr495) were also upregulated by high glucose. In contrast, the anti-inflammatory factor Nrf2 and the activating phosphorylation of eNOS (Ser1177) were downregulated. Similar to the change of OPN, phosphorylated P38 was increased with high glucose. SB203580, an inhibitor of P38 phosphorylation, downregulated the expression of OPN and related inflammatory factors. Additionally, OPN was increased in the aortas and plasma of diabetic rats. In conclusion, our findings demonstrate that high glucose can induce the expression of OPN, which may be a key factor in the calcification and dysfunction of the vascular wall in diabetes.

    This study was to determine the effects of five-week high-intensity interval training (HIIT) on cardiorespiratory fitness, body composition, blood glucose, and relevant systemic hormones when compared to moderate-intensity continuous training (MICT) in overweight and obese young women. Methods. Eighteen subjects completed 20 sessions of HIIT or MICT for five weeks. HIIT involved 60 × 8 s cycling at ~90% of peak oxygen consumption ([Formula: see text]) interspersed with 12 s recovery, whereas MICT involved 40-minute continuous cycling at 65% of [Formula: see text]. [Formula: see text], body composition, blood glucose, and fasting serum hormones, including leptin, growth hormone, testosterone, cortisol, and fibroblast growth factor 21, were measured before and after training. Results. Both exercise groups achieved significant improvements in [Formula: see text] (+7.9% in HIIT versus +11.7% in MICT) and peak power output (+13.8% in HIIT versus +21.9% in MICT) despite no training effects on body composition or the relevant systemic hormones. Blood glucose tended to be decreased after the intervention (p = 0.062). The rating of perceived exertion in MICT was higher than that in HIIT (p = 0.042). Conclusion. Compared with MICT, short-term HIIT is more time-efficient and is perceived as being easier for improving cardiorespiratory fitness and fasting blood glucose for overweight and obese young women.

    Fluorescent test papers are promising for the wide applications in the assays of diagnosis, environments and foods, but unlike classical dye-absorption-based pH test paper, they are usually limited in the qualitative yes/no type of detection by fluorescent brightness, and the colorimetry-based quantification remains a challenging task. Here, we report a single dual-emissive nanofluorophore probe to achieve the consecutive color variations from blue to red for the quantification of blood glucose on its as-prepared test papers. Red quantum dots were embedded into silica nanoparticles as a stable internal standard emission, and blue carbon dots (CDs) were further covalently linked onto the surface of silica, in which the ratiometric fluorescence intensity of blue to red is controlled at 5:1. While the oxidation of glucose induced the formation of Fe(3+) ions, the blue emission of CDs was thus quenched by the electron transfer from CDs to Fe(3+), displaying a serial of consecutive color variations from blue to red with the dosage of glucose. The high-quality test papers printed by the probe ink exhibited a dosage-sensitive allochromatic capability with the clear differentiations of ~5, 7, 9, 11mM glucose in human serum (normal: 3-8mM). The blood glucose determined by the test paper was almost in accordance with that measured by a standard glucometer. The method reported here opens a window to the wide applications of fluorescent test paper in biological assays.

It is a difficult task to perform due to the complexity of the glucose-insulin regulation system. The variety of model existing reflects the great amount of phenomena involved in the process, and the inter-patient variability of the parameters represent another challenge. In this research a High-Order Sliding-Mode Control is proposed. It is applied to two well known models, Bergman Minimal Model, and Sorensen Model, to test its robustness with respect to uncertain dynamics, and patients' parameter variability. The controller designed based on the simulations is tested with the specific Bergman Minimal Model of a diabetic patient whose parameters were identified from an in vivo assay. To minimize the insulin infusion rate, and avoid the hypoglycemia risk, the glucose target is a dynamical profile.

    One of the main pathological symptoms of early diabetic retinal neuropathy is retina neuronal apoptosis. In the present work we investigated the effects of indoleamine hormone melatonin, a powerful free radical scavenger, on streptozotocin-induced retina neuronal cell apoptosis in high blood glucose rat. After melatonin treatment (10 mg/kg/day), tunel detection was used to monitor the apoptosis rate of neurons in the retinal ganglion cell layer; reversed quantitative PCR was used to measure the mRNA expression of retinal caspase-3, Mn superoxidase dismutase (SOD) and Cu-Zn SOD; and the activities of total SOD (T-SOD) and sub-type SOD was detected using xanthine oxidase enzymatic detection. Our data showed that melatonin treatment leads to a decrease of retinal cell apoptosis and the apoptotic index was (1.67 ± 0.54) % and (7.73 ± 0.95) % at 8 and 12 weeks after treatment. The relative quantitative (RQ) value for caspase-3 mRNA expression was (6.996 ± 1.192) and (7.267 ± 1.178) in melatonin group, which are much lower than the values of diabetic group (12.566 ± 2.272 and (14.297 ± 2.110) at 8 and 12 weeks, respectively) under the same condition. mRNA expression of Mn SOD and Cu-Zn SOD as well as their activities all decreased in the diabetic group compared with the control group. While melatonin treatment induced the expression of Mn SOD mRNA and a continual increase of Mn SOD activity as well as the activity and mRNA expression of Cu-Zn SOD at 12 weeks. Therefore, our results demonstrate that melatonin treatment prevented the decrease in mRNA expression of SOD and the increase in caspase-3 mRNA expression induced by diabetes thus exerts a beneficial effect on retina neuronal apoptosis.

    Full Text Available Global prevalence increase of diabetes type 2 and gestational diabetes (GDM has led to increased awareness and screening of pregnant women for GDM. Ideally screening for GDM should be done by an oral glucose tolerance test (oGTT, which is laborious and time consuming. A randomized glucose test incorporated with anthropomorphic characteristics may be an appropriate cost-effective combined clinical and biochemical screening protocol for clinical practice as well as cutting down on oGTTs. A retrospective observational study was performed on a randomized sample of pregnant women who required an OGTT during their pregnancy. Biochemical and anthropomorphic data along with obstetric outcomes were statistically analyzed. Backward stepwise logistic regression and receiver operating characteristics curves were used to obtain a suitable predictor for GDM without an oGTT and formulate a screening protocol. Significant GDM predictive variables were fasting blood glucose (p=0.0001 and random blood glucose (p=0.012. Different RBG and FBG cutoff points with anthropomorphic characteristics were compared to carbohydrate metabolic status to diagnose GDM without oGTT, leading to a screening protocol. A screening protocol incorporating IADPSG diagnostic criteria, BMI, and different RBG and FBG criteria would help predict GDM among high-risk populations earlier and reduce the need for oGTT test.

    Full Text Available The objective of this work was to examine the effect of heat stress on glucose and pH values in blood of high-yielding dairy cows in the early stage of lactation, as well as to determine whether the changes in these parameters are interdependent under such conditions. An experiment was performed on high-yielding dairy cows during the summer and the spring periods. Forty cows were selected, twenty each for the two periods under investigation. In the course of the experiment, the temperature humidity index (THI was determined for the entire period of investigations, and then also the average daily THI, nightmorning THI (average value of hourly THI measured from 22h on the previous day until 10h of the current day, as well as the day-night THI (average value of hourly THI measured during the period from 10h to 22h of the current day. The pH and glucose concentration were determined in blood samples taken in the morning and afternoon of days 30, 60, and 90 of lactation during the spring and summer periods of the investigations. Based on the results for the THI, it was established that the animals were not exposed to the effect of extreme heat stress during the spring period of investigations, while they were periodically exposed to moderate but also extreme heat stress during the summer, in particular in the afternoon hours. It can be concluded from the results obtained for the blood pH that the cows were in respiratory alkalosis during the summer in the morning and afternoon hours on day 30, in the afternoon hours of days 60 and 90 of lactation, as well as in the afternoon on day 90 of lactation during the spring period of investigations. During the summer period, there were no statistically significant differences between the pH value determined in the morning and afternoon hours on day 30 of lactation, while the pH value was significantly higher in the afternoon hours than in the morning hours on days 60 and 90 of lactation. There were no

    Type 2 diabetes (noninsulin-dependent diabetes mellitus) develops from a pre-diabetic condition that is characterized by insulin resistance and glucose intolerance, and is exacerbated by obesity. In this study, we compared the ability of over-the-counter analgesic drugs (OTCAD) [acetaminophen (APAP); ibuprofen (IBU); naproxen (NAP); aspirin (ASA)], to protect against the development of a pre-diabetic state in mice fed a high fat diet. After 10 weeks on the high fat diet, mice had normal fasting blood glucose (FBG) levels, but exhibited impaired glucose tolerance. Treatment with 20 mg OTCADs/kg body weight improved glucose tolerance, with the order of efficacy, APAP=ASA>IBU, while NAP proved ineffective. Mice fed the high fat diet also exhibited increases in weight gain associated with an increase in body fat. OTCADs prevented in part this increase in body fat, in the order of efficacy, APAP=IBU>NAP=ASA. In isolated liver mitochondria, OTCADs inhibited succinate-dependent H2O2 production, while in white adipose tissue, APAP inhibited NADPH-oxidase mediated H2O2 production and lipid peroxidation. Thus, OTCADs diminish pro-oxidant processes that might otherwise exacerbate inflammation and a pre-diabetic state. We conclude that OTCADs, especially APAP and IBU, may be valuable tools to delay or prevent the development of type 2 diabetes from a pre-diabetic condition.

    The amount of glucose in the circulation depends on its absorption from the intestine, uptake by and release from the liver and uptake by peripheral tissues. Insulin and glucagon together control the metabolities required by peripheral tissues and both are involved in maintaining glucose homeostasis. Insulin is considered to be an anabolic hormone in that it promotes the synthesis of protein, lipid and glycogen. The key target tissues for insulin are liver, muscles and adipose tissue. Glucagon acts largely to increase catabolic processes. Between meals or during fast, the most tightly regulated process is the release of glucose from the liver. During fasting glucose is produced from glycogen and is formed by enzymes on the gluconeogenic pathway. Fetal metabolism is directed to ensure anabolism with formation of glycogen, fat and protein. Glucogen is stored in the liver and serves as the immediate source of new glucose during first few hours after birth. Glucose is the most important substrate for brain metabolism. Due to the large size of neonatal brain in relation to body weight cerebral glucose consumption is particularly high. Postnatal hormonal changes have a central role in regulating glucose mobilization through glycogenolysis and gluconeogenesis. The initial glucagon surge is the key adaptive change which triggers the switch to glucose production. The control of insulin and glucagon secretion is of fundamental importance during first hours after birth. Children have a decreased tolerance to starvation when compared with adults, they are more prone to develop hypoglycaemia after short fasting. The faster rate in the fall of blood glucose and gluconeogenic substrates and rapid rate of ketogenesis are characteristic features of fasting adaptation in children.

  3. Development of a high-sensitivity and portable cell using Helmholtz resonance for noninvasive blood glucose-level measurement based on photoacoustic spectroscopy.

    2016-08-01

    We describe the possibility of high-sensitivity noninvasive blood glucose measurement based on photoacoustic spectroscopy (PAS). The demand for noninvasive blood glucose-level measurement has increased due to the explosive increase in diabetic patients. We have developed a noninvasive blood glucose-level measurement based on PAS. The conventional method uses a straight-type resonant cell. However, the cell volume is large, which results in a low detection sensitivity and difficult portability. In this paper, a small-sized Helmholtz-type resonant cell is proposed to improve detection sensitivity and portability by reducing the cell dead volume. First, the acoustic property of the small-sized Helmholtz-type resonant cell was evaluated by performing an experiment using a silicone rubber. As a result, the detection sensitivity of the small-sized Helmholtz-type resonant cell was approximately two times larger than that of the conventional straight-type resonant cell. In addition, the inside volume was approximately 30 times smaller. Second, the detection limits of glucose concentration were estimated by performing an experiment using glucose solutions. The experimental results showed that a glucose concentration of approximately 1% was detected by the small-sized Helmholtz-type resonant cell. Although these results on the sensitivity of blood glucose-level measurement are currently insufficient, they suggest that miniaturization of a resonance cell is effective in the application of noninvasive blood glucose-level measurement.

    Accurate self-monitoring of blood glucose is a key component of effective self-management of glycemic control. The OneTouch VerioFlex(™) (OTVF) blood glucose monitoring system (BGMS) was evaluated for accuracy in a clinical setting. Patients also used OTVF for a 1-wk trial period and reported their level of satisfaction with meter features. In a separate study, healthcare professionals used an on-line simulator of the BGMS and answered questions about its potential utility to their patients. OTVF was accurate over a wide glucose range and met lay user and system accuracy blood glucose standards described in ISO15197:2013 as well as the accuracy requirements to fulfill US FDA expectations for 510(k) clearance of BGMS. Patients and healthcare professionals felt the features of OTVF, which has the capability to connect wirelessly to mobile devices and interact wirelessly with diabetes management software, could provide significant benefits to them or their patients.

    The controversy as to the relationship between the degree of control of diabetes and the progression of the complications of the disease has not been solved. However, in this review, various studies suggesting a relationship between the metabolic abnormality and the diabetic complications are examined. The disadvantages of the uncontrolled diabetes mellitus can be divided into two major categories-short-term and long-term. The short-term disadvantages of controlled diabetes mellitus include the following: (1) ketoacidosis and hyperosmolar coma; (2) intracellular dehydration; (3) electrolyte imbalance; (4) decreased phagocytosis; (5) immunologic and lymphocyte activity; (6) impairment of wound healing; and (7) abnormality of lipids. The long-term disadvantages of uncontrolled diabetes melitus include the following: (1) nephropathy; (2) neuropathy; (3) retinopathy; (4) cataract formation; (5) effect on perinatal mortality; (6) complications of vascular disease; and (7) the evaluation of various clinical studies suggesting the relationship of elevated blood glucose levels and complications of diabetes mellitus. It is suggested that until the question of control can absolutely be resolved, the recommendation is that the blood glucose levels should be controlled as close to the normal as possible.

    The aim of the study is to evaluate work-related subjective stress in a group of workers on a major Italian company in the field of healthcare through the administration of a valid "questionnaire-tool indicator" (HSE Indicator Tool), and to analyze any correlation between stress levels taken from questionnaire scores and blood glucose values. We studied a final sample consisting of 241 subjects with different tasks. The HSE questionnaire - made up of 35 items (divided into 7 organizational dimensions) with 5 possible answers - has been distributed to all the subjects in occasion of the health surveillance examinations provided by law. The questionnaire was then analyzed using its specific software to process the results related to the 7 dimensions. These results were compared using the Pearson correlation and multiple linear regression with the blood glucose values obtained from each subject. From the analysis of the data the following areas resulted critical, in other words linked to an intermediate (yellow area) or high (red area) condition of stress: sustain from managers, sustain from colleagues, quality of relationships and professional changes. A significant positive correlation (p <0.05) between the mean values of all critical areas and the concentrations of glucose values have been highlighted with the correlation index of Pearson. Multiple linear regression confirmed these findings, showing that the critical dimensions resulting from the questionnaire were the significant variables that can increase the levels of blood glucose. The preliminary results indicate that perceived work stress can be statistically associated with increased levels of blood glucose.

    Full Text Available Diabetes Mellitus (DM is a syndrome in metabolism of carbohydrates which indicated by the increased level of blood glucose and also may increase salivary glucose levels. Oral ulcer has been frequently recognized in diabetic patients, which can be due to increased glucose in oral fluids and immune dysfunction. This study aimed to determine the correlation of blood glucose levels and salivary glucose levels with oral ulcer in diabetic patients. Analytic observational study was carried out through the determination of blood glucose levels just by way of strip using a glucometer and salivary glucose levels with the method "GOD-PAP test enzymatic colorimetric". Oral ulcer was determined in presenting ulcer on 30 patients with DM. The results showed r = 0.228, which is higher salivary glucose levels followed by high levels of blood glucose, and intraoral examination of oral ulcer found in the whole sample and the most location commonly found in buccal mucosa and lingual. It was concluded that there is a correlation between blood glucose levels and salivary glucose levels, and glucose levels affect the occurrence of oral ulcer in patients with DM

  12. A high isoflavone diet decreases 5' adenosine monophosphate-activated protein kinase activation and does not correct selenium-induced elevations in fasting blood glucose in mice.

    Selenium (Se) has been implicated as a micronutrient that decreases adenosine monophosphate-activated protein kinase (AMPK) signaling and may increase diabetes risk by reducing insulin sensitivity. Soy isoflavones (IF) are estrogen-like compounds that have been shown to attenuate insulin resistance, hyperglycemia, adiposity, and increased AMPK activation. We hypothesized that a high IF (HIF) diet would prevent the poor metabolic profile associated with high Se intake. The purpose of this study was to examine changes in basal glucose metabolism and AMPK signaling in response to an HIF diet and/or supplemental Se in a mouse model. Male FVB mice were divided into groups receiving either a control diet with minimal IF (low IF) or an HIF diet. Each dietary group was further subdivided into groups receiving either water or Se at a dose of 3 mg Se/kg body weight daily, as Se-methylselenocysteine (SMSC). After 5 months, mice receiving SMSC had elevated fasting glucose (P < .05) and a tendency for glucose intolerance (P = .08). The increase in dietary IF did not result in improved fasting blood glucose. Interestingly, after 6 months, HIF-fed mice had decreased basal AMPK activation in liver and skeletal muscle tissue (P < .05). Basal glucose metabolism was changed by SMSC supplementation as evidenced by increased fasting blood glucose and glucose intolerance. High dietary IF levels did not protect against aberrant blood glucose. In FVB mice, decreased basal AMPK activation is not the mechanism through which Se exerts its effect. These results suggest that more research must be done to elucidate the role of Se and IF in glucose metabolism.

    2016-11-01

    Full Text Available Ketoacidosis is a significant and often a life-threatening complication of diabetes mellitus seen mostly in type 1 diabetes mellitus as well as occasionally in type 2 diabetes mellitus. Diabetic ketoacidosis usually manifests with high blood glucose more than 250 mg/dL, but euglycemic diabetic ketoacidosis is defined as ketoacidosis associated with blood glucose level less than 250 mg/dL. Normal blood glucose in such patients results in significant delay in diagnosis and management of diabetic ketoacidosis, thus increasing mortality and morbidity. We present a case of euglycemic diabetic ketoacidosis secondary to canagliflozin in a type 2 diabetic patient.

    This study aimed to evaluate the performance of a glucose pattern recognition tool incorporated in a blood glucose monitoring system (BGMS) and its association with clinical measures, and to assess user perception and understanding of the pattern messages they receive. Participants had type 1 or type 2 diabetes mellitus and were self-adjusting insulin doses for ≥1 year. During a 4-week home testing period, participants performed ≥6 daily self-tests, adjusted their insulin regimen based on BGMS results, and recorded pattern messages in the logbook. Participants reflected on usability of the pattern tool in a questionnaire. Study participants (n = 101) received a mean ± standard deviation of 4.5 ± 1.9 pattern messages per week (3.6 ± 1.8 high glucose patterns and 0.9 ± 1.3 low glucose patterns). Most received ≥1 high (96.5%) and/or ≥1 low (46.0%) pattern message per week. The average number of high- and low-pattern messages per week was associated with higher and lower, respectively, baseline hemoglobin A1c (p < .01) and fasting plasma glucose (p < .05). Participants found high- and low-pattern messages clear and easy to understand (84.2% and 83.2%, respectively) and considered the frequency of low (82.0%) and high (63.4%) pattern messages about right. Overall, 71.3% of participants indicated they preferred to use a meter with pattern messages. The on-device Pattern tool identified meaningful blood glucose patterns, highlighting potential opportunities for improving glycemic control in patients who self-adjust their insulin. © 2013 Diabetes Technology Society.

    1997-04-26

    A 41-year-old man died in 1995 during ketoacidotic coma. He suffered from chronic manic depression, used lithium carbonate, and consulted the psychiatrist and the general practitioner (GP) frequently. Diabetes had not been diagnosed. Late in 1994 the situation worsened, the patient complaining of general illness, fatigue, nausea, vomiting, diarrhoea, thirst and excessive drinking of soft drinks. The GP referred the patient to a neurologist who found no neurological disorder but who asked for determination of blood glucose and lithium levels, and of thyroid function. The day afterwards the neurologist went on holiday. The blood glucose level proved to be elevated (16.9 mmol/1) but nobody took any action and the GP was not informed. Six days after returning from his holiday, the neurologist who had an administration backlog, found the laboratory findings only after he had been informed that the patient had just died. The court gave the neurologist a warning. Lessons are that somatic problems should be treated as such, even in a psychiatric patient, and that a good administrative signalling system is a prerequisite for quality in medical practice.

  8. A tale of two compartments: interstitial versus blood glucose monitoring.

    2009-06-01

    Self-monitoring of blood glucose was described as one of the most important advancements in diabetes management since the invention of insulin in 1920. Recent advances in glucose sensor technology for measuring interstitial glucose concentrations have challenged the dominance of glucose meters in diabetes management, while raising questions about the relationships between interstitial and blood glucose levels. This article will review the differences between interstitial and blood glucose and some of the challenges in measuring interstitial glucose levels accurately.

    The objective of this study was to determine the dose response effect of whole grain high-amylose maize (HAM) flour as a source of resistant starch (RS) on blood glucose, appetite and short-term food intake. In a repeated-measures crossover trial, healthy men (n = 30, 22.9 ± 0.6 y, BMI of 22.6 ± 0.3 kg/m(2)) were randomly assigned to consume 1 of 3 cookies once a week for 3 wk. Cookies were control (100% wheat flour), low-dose (63% wheat flour,37% HAM flour), and high-dose (33% wheat flour, 67% HAM flour) providing 53.5, 43.5, and 36.3 g of available carbohydrate, respectively. Ad libitum food intake was measured 120 min at a pizza meal, blood glucose and subjective appetite were measured after consumption of the cookie (0 to 120 min) and after the pizza meal (140 to 200 min). Blood glucose concentrations were lower at 30 and 45 min after high-dose treatment, and at 120 min after both high- and low-dose treatments compared to control (P < 0.05). Blood glucose AUC before the pizza meal (0 to 120 min) was 44% and 14% lower, and higher by 43% and 41% after the pizza meal (140 to 200 min) compared with control. Yet despite the higher response following the meal, cumulative AUC (0 to 200 min) was still 22% lower after the high-dose treatment (P < 0.05). All treatments equally suppressed subjective appetite and there was no effect on food intake. In conclusion, HAM flour as a source of RS and incorporated into a cookie was associated with better glycemic control in young men.

    2002-12-01

    To evaluate the precision and accuracy of a new advanced prototype of a noninvasive blood glucose monitor across a wide range of serum glucose concentrations. An advanced handheld noninvasive glucose monitor prototype was calibrated and tested using patients recruited by the General Research Center of the University of Connecticut Health Center. The monitor, developed by Infratec, uses principles of thermal emission spectroscopy. The noninvasive measurement of tympanic membrane glucose concentration was calibrated to the serum glucose concentration using 432 paired measurements from 20 subjects with insulin-requiring diabetes. This calibration was subsequently tested (results of power analyses) in a blind fashion with 126 paired measurements from six diabetic subjects who require insulin. In vivo measurements demonstrated the reproducibility of the methodology of the noninvasive glucose monitor. Based on the calibration model, predicted glucose concentrations for six subjects were as follows (for 126 data points): SD = 32 mg/dl, mean absolute relative error (%MARE) = 11.6, with a correlation coefficient of r = 0.87. Noninvasive glucose results were also compared with laboratory reference measurements using an error-in-variables method. Clark error grid analysis showed that 100% of the measurements fell within zones A and B (90% in zone A and 10% in zone B). The SD for all noninvasive measured concentrations was 27 mg/dl, %MARE was 8.6, and the correlation coefficient was r = 0.94. This first independent clinical study of an advanced noninvasive blood glucose prototype based on thermal emission in the mid-infrared spectral region has demonstrated glucose measurements with clinically acceptable accuracy but without the necessity of individual daily calibration.

  11. Discrepancies Between Blood Glucose and Interstitial Glucose-Technological Artifacts or Physiology: Implications for Selection of the Appropriate Therapeutic Target.

    Science.gov (United States)

    Siegmund, Thorsten; Heinemann, Lutz; Kolassa, Ralf; Thomas, Andreas

    2017-07-01

    For decades, the major source of information used to make therapeutic decisions by patients with diabetes has been glucose measurements using capillary blood samples. Knowledge gained from clinical studies, for example, on the impact of metabolic control on diabetes-related complications, is based on such measurements. Different to traditional blood glucose measurement systems, systems for continuous glucose monitoring (CGM) measure glucose in interstitial fluid (ISF). The assumption is that glucose levels in blood and ISF are practically the same and that the information provided can be used interchangeably. Thus, therapeutic decisions, that is, the selection of insulin doses, are based on CGM system results interpreted as though they were blood glucose values. We performed a more detailed analysis and interpretation of glucose profiles obtained with CGM in situations with high glucose dynamics to evaluate this potentially misleading assumption. Considering physical activity, hypoglycemic episodes, and meal-related differences between glucose levels in blood and ISF uncover clinically relevant differences that can make it risky from a therapeutic point of view to use blood glucose for therapeutic decisions. Further systematic and structured evaluation as to whether the use of ISF glucose is more safe and efficient when it comes to acute therapeutic decisions is necessary. These data might also have a higher prognostic relevance when it comes to long-term metabolic consequences of diabetes. In the long run, it may be reasonable to abandon blood glucose measurements as the basis for diabetes management and switch to using ISF glucose as the appropriate therapeutic target.

    We investigated the effect of fasting blood glucose and body mass index (BMI) at diagnosis on risk of breast cancer death for cases diagnosed in five Italian cancer registries in 2003-2005 and followed up to the end of 2008. For 1607 Italian women (≥15 years) with information on BMI or blood glucose or diabetes, we analysed the risk of breast cancer death in relation to glucose tertiles (≤84.0, 84.1-94.0, >94.0 mg/dl) plus diabetic and unspecified categories; BMI tertiles (≤23.4, 23.5-27.3, >27.3 kg/m(2), unspecified), stage (T1-3N0M0, T1-3N+M0 plus T4anyNM0, M1, unspecified), oestrogen (ER) and progesterone (PR) status (ER+PR+, ER-PR-, ER and PR unspecified, other), age, chemotherapy and endocrine therapy, using multiple regression models. Separate models for ER+PR+ and ER-PR- cases were also run. Patients often had T1-3N0M0, ER+PR+ cancers and received chemotherapy or endocrine therapy; only 6% were M1 and 17% ER-PR-. Diabetic patients were older and had more often high BMI (>27 kg/m(2)), ER-PR-, M1 cancers than other patients. For ER+PR+ cases, with adjustment for other variables, breast cancer mortality was higher in women with high BMI than those with BMI 23.5-27.3 kg/m(2) (hazard ratio (HR)=2.9, 95% confidence interval (CI) 1.2-6.9). Breast cancer mortality was also higher in women with high (>94 mg/dl) blood glucose compared to those with glucose 84.1-94.0mg/dl (HR=2.6, 95% CI 1.2-5.7). Our results provide evidence that in ER+PR+ patients, high blood glucose and high BMI are independently associated with increased risk of breast cancer death. Detection and correction of these factors in such patients may improve prognosis. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Blood glucose concentration was measured in 84 pediatric patients who were scheduled for outpatient surgery at Chulalongkorn Hospital. They were allocated into 3 groups according to their ages, group 1:less than 1 year of age, group 2:1 to 5 years of age and group 3:over 5 years. The fasting times were approximately 8-12 hours. All patients received standard general anesthesia under mask. No glucose solution was given during operation. Preoperative mean blood glucose were 91.09 +/- 17.34, 89.55 +/- 18.69 and 82.14 +/- 16.14 mg/dl in group 1, 2 and 3 while the postoperative mean glucose values were 129.07 +/- 37.90, 115.62 +/- 29.63 and 111.53 +/- 23.07 mg/dl respectively. The difference between pre- and post-operative values were statistically significant difference (P postoperative glucose values may be due to stress response from surgery and anesthesia. We would suggest that the parents give the fluid to their children according to our instructions in order to prevent dehydration and hypoglycemia especially in small infants.

    2017-07-01

    To investigate the comparability of glucose levels measured with blood gas analyzers (BGAs) and by central laboratories (CLs). Glucose measurements obtained between June 1, 2007, and March 1, 2016, at the Vanderbilt University Medical Center were reviewed. The agreement between CL and BGA results were assessed using Bland-Altman, consensus error grid (CEG), and surveillance error grid (SEG) analyses. We further analyzed the BGAs' performance against the US Food and Drug Administration (FDA) 2014 draft guidance and 2016 final guidance for blood glucose monitoring and the International Organization for Standardization (ISO) 15197:2013 standard. We analyzed 2671 paired glucose measurements, including 50 pairs of hypoglycemic values (1.9%). Bland-Altman analysis yielded a mean bias of -3.1 mg/dL, with 98.1% of paired values meeting the 95% limits of agreement. In the hypoglycemic range, the mean bias was -0.8 mg/dL, with 100% of paired values meeting the 95% limits of agreement. When using CEG analysis, 99.9% of the paired values fell within the no risk zone. Similar results were found using SEG analysis. For the FDA 2014 draft guidance, our data did not meet the target compliance rate. For the FDA 2016 final guidance, our data partially met the target compliance rate. For the ISO standard, our data met the target compliance rate. In this study, the agreement for glucose measurement between common BGAs and CL instruments met the ISO 2013 standard. However, BGA accuracy did not meet the stricter requirements of the FDA 2014 draft guidance or 2016 final guidance. Fortunately, plotting these results on either the CEG or the SEG revealed no results in either the great or extreme clinical risk zones.

    1986-10-01

    Home glucose monitoring with the use of reflectance meters is an important adjunct in the care of pregnant women with insulin-dependent diabetes. The accuracy of reflectance meters for the assay of capillary glucose specimens has been well documented. The present preliminary study was undertaken to determine the utility of outpatient screening for gestational diabetes mellitus with the use of a reflectance meter (Accu-Chek, Boehringer Mannheim Co.). One hundred twenty-five patients in our high-risk practice had a standard 50 gm glucose load at 26 to 28 weeks' gestation. Capillary glucose values were measured on site with the Accu-Chek. Venous plasma glucose levels were measured by the central laboratory chemistry analyzer. While the laboratory (x) and meter (y) glucose determinations between the two sets of values were highly correlated (R = 0.89, p less than 0.001), there was a significant difference in their average values (x = 111.74, y = 136.35, p less than 0.0001). With the use of a receiver operator characteristic curve, a meter value of 160 mg/dl was determined as the optimal threshold for performing a 3-hour glucose tolerance test. The sensitivity and specificity with the use of a meter value of 160 mg/dl were 93% and 96%, respectively, for detecting an abnormal screening test in venous plasma (greater than or equal to 135 mg/dl). A total of 32 glucose tolerance tests were performed, with four patients included who had venous values less than 135 mg/dl. All eight patients with gestational diabetes mellitus were correctly identified. These data suggest that a glucose reflectance meter can be used for accurate outpatient screening of gestational diabetes mellitus. The potential advantages of capillary blood glucose screening include both cost and efficiency. Patients with abnormal screening values can be promptly identified and scheduled for a follow-up 3-hour glucose tolerance test.

  3. Blood-Brain Glucose Transfer: Repression in Chronic Hyperglycemia

    Science.gov (United States)

    Gjedde, Albert; Crone, Christian

    1981-10-01

    Diabetic patients with increased plasma glucose concentrations may develop cerebral symptoms of hypoglycemia when their plasma glucose is rapidly lowered to normal concentrations. The symptoms may indicate insufficient transport of glucose from blood to brain. In rats with chronic hyperglycemia the maximum glucose transport capacity of the blood-brain barrier decreased from 400 to 290 micromoles per 100 grams per minute. When plasma glucose was lowered to normal values, the glucose transport rate into brain was 20 percent below normal. This suggests that repressive changes of the glucose transport mechanism occur in brain endothelial cells in response to increased plasma glucose.

    Hyperglycaemia, a characteristic feature of diabetes mellitus, induces endothelial dysfunction and vascular complications by limiting the proliferative potential of these cells. Here we aimed to investigate the effect of an ethanolic extract of Sanguis draconis (SD), a kind of dragon's blood resin that is obtained from Daemonorops draco (Palmae), on human umbilical vein endothelial cells (HUVEC) under high-glucose (HG) stimulation and its underlying mechanism. Concentration-dependent (0-50 μg/mL) assessment of cell viability showed that SD does not affect cell viability with a similar trend up to 48 h. Remarkably, SD (10-50 μg/mL) significantly attenuated the high-glucose (25 and 50 mM) induced cell toxicity in a concentration-dependent manner. SD inhibited high glucose-induced nitrite (NO) and lipid peroxidation (MDA) production and reactive oxygen species (ROS) formation in HUVEC. Western blot analysis revealed that SD treatments abolished HG-induced phosphorylation of extracellular signal-regulated kinase 1/2 (ERK 1/2), nuclear transcription factor, κB (NF-κB), VCAM-1, and E-selectin, and it also blocked the breakdown of PARP-116 kDa protein in a dose-dependent manner. Furthermore, we found that SD increased the expression of Bcl-2 and decreased Bax protein expression in HG-stimulated HUVEC. Thus, these results of this study demonstrate for the first time that SD inhibits glucose induced oxidative stress and vascular inflammation in HUVEC by inhibiting the ERK/NF-κB/PARP-1/Bax signaling cascade followed by suppressing the activation of VCAM-1 and E-selectin. These data suggest that SD may have a therapeutic potential in vascular inflammation due to the decreased levels of oxidative stress, apoptosis, and PARP-1 activation.

    Full Text Available Hyperglycaemia, a characteristic feature of diabetes mellitus, induces endothelial dysfunction and vascular complications by limiting the proliferative potential of these cells. Here we aimed to investigate the effect of an ethanolic extract of Sanguis draconis (SD, a kind of dragon’s blood resin that is obtained from Daemonorops draco (Palmae, on human umbilical vein endothelial cells (HUVEC under high-glucose (HG stimulation and its underlying mechanism. Concentration-dependent (0–50 μg/mL assessment of cell viability showed that SD does not affect cell viability with a similar trend up to 48 h. Remarkably, SD (10–50 μg/mL significantly attenuated the high-glucose (25 and 50 mM induced cell toxicity in a concentration-dependent manner. SD inhibited high glucose-induced nitrite (NO and lipid peroxidation (MDA production and reactive oxygen species (ROS formation in HUVEC. Western blot analysis revealed that SD treatments abolished HG-induced phosphorylation of extracellular signal-regulated kinase 1/2 (ERK 1/2, nuclear transcription factor, κB (NF-κB, VCAM-1, and E-selectin, and it also blocked the breakdown of PARP-116 kDa protein in a dose-dependent manner. Furthermore, we found that SD increased the expression of Bcl-2 and decreased Bax protein expression in HG-stimulated HUVEC. Thus, these results of this study demonstrate for the first time that SD inhibits glucose induced oxidative stress and vascular inflammation in HUVEC by inhibiting the ERK/NF-κB/PARP-1/Bax signaling cascade followed by suppressing the activation of VCAM-1 and E-selectin. These data suggest that SD may have a therapeutic potential in vascular inflammation due to the decreased levels of oxidative stress, apoptosis, and PARP-1 activation.

    A number of factors may lead to inaccuracy in measurement of capillary blood glucose with a glucometer. Measurement of other carbohydrate molecules such as galactose and fructose along with glucose can potentially be a cause of error. We report a newborn patient who was referred to our hospital with conjugated bilirubinemia, hepatomegaly and high capillary blood glucose levels measured with a glucometer. Simultaneous biochemical measurements revealed normal blood glucose levels. Further investigation led to a diagnosis of classical galactosemia. Capillary blood glucose level measured with glucometer also dropped to normal values following cessation of breastfeeding and initiation of feeding with a lactose-free formula.

    Full Text Available Glucose and glycated hemoglobin (Hb in the blood of camel (Camelus dromedarius and cow (Bos taurus were analyzed and compared with human values. Camel displayed high blood glucose concentration (9.7±2.8 mM but a low level of glycated-Hb (3.4± 0.23%.Cow blood samples did not show sufficient variations in glucose concentrations (5.7±0.73 mM or glycated Hb levels (3.2± 0.11% compared to human values. The low glycation of camel Hb at higher glucose concentrations suggest that certain factors protect the Hb from glycation at high glucose concentrations. Camel Hb also exhibited a higher electrophoretic mobility than normal hemoglobin of human or cow. Camel Hb migrated at a rate corresponding to that of human Hb-C. Bioinformatics tools were used to explore the biochemical basis for the difference in camel Hb migratory position and its apparent resistance to glycation.

    Most methods used to measure glucose concentrations in biotechnological settings are labour-intensive and/or expensive. With this in mind we have investigated the possibility of employing blood glucose meters, the use of which has the benefit of being fast, convenient and inexpensive, for this purpose. Accu-Chek Advantage (Roche Diagnostics, Indianapolis, IN, U.S.A.) and Precision QID (Medisense, Abbott Laboratories, Indianapolis, IN, U.S.A.) meters were tested using glucose samples of known concentration, at pH 7.5 and 4.8. The Accu-Chek Advantage meter uses strips containing the enzyme glucose dehydrogenase. This meter showed a linear response for glucose concentrations between 0.50 and 6.0 g/litre, and the effect of pH was small. The Precision QID meter uses strips containing the enzyme glucose oxidase and is more sensitive to pH. The displayed glucose concentrations at low pH values were consistently lower than at higher pH values. At both pH values the response curve reached a plateau, which limited the effective range of this meter to a range of 0.30-2.5 g/litre. Unlike the Precision QID meter, the Accu-Chek Advantage meter also responded to xylose and arabinose. A synergistic effect of combining sugars was observed when a mixture of sugars consisting of glucose and arabinose, or glucose and xylose, was applied: the displayed concentrations were consistently higher than was expected on the basis of the individual calibration curves. The use of glucose meters is a fast and convenient alternative to existing methods and may be of particular use for screening purposes where a high degree of accuracy is not crucial. The choice of meter should depend on the application, and in this respect the pH, expected concentration range and the presence of other sugars are among the factors that should be considered.

    There is a growing body of studies suggesting that NIR spectroscopy is feasible to be used to non-invasive blood glucose sensing. However, previous results reported that blood components are very complicated and in which glucose concentration is relatively low. This feature limited the practical application of NIR spectroscopy to in vivo blood glucose detection. This talk aims to elucidate how the cholesterol influences blood glucose sensing. Spectroscopic measurements show that cholesterol appears the similar absorbance peaks to those of glucose within NIR range. Furthermore, PLS modelling results demonstrate that the measurement concentrations of glucose are on the high side while containing cholesterol. For example, when the cholesterol concentration is 200mg/dl, the measurement result of glucose with near-infrared spectroscopy will increase 7.961882mg/dl comparing to cholesterol-free glucose solution. Therefore, it is necessary to take steps to reduce cholesterol's effects.

    Objective: According to our previous studies, propolis of Nigerian origin showed some evidence of hypoglycemic and hypolipidemic activities in addition to its ability to ameliorate oxidative-stress-induced organ dysfunction. This study was carried out to determine whether an ethanolic extract of Nigerian propolis (EENP) improves glycated hemoglobin A1c (HbA1c), fasting plasma glucose, very low-density lipoprotein (VLDL), and high-density lipoprotein (HDL) concentrations in rats that have alloxan diabetes. Materials and Methods: Diabetes was induced with alloxan (110 mg/kg). Animals were divided into 5 groups (n = 5); Group 1 was non-diabetic receiving normal saline and Group 2 was diabetic but also received only normal saline. Groups 3, 4, and 5 were diabetic receiving 200 mg/kg propolis, 300 mg/kg propolis, and 150 mg/kg metformin, respectively, for 42 days. Results: Hyperglycemia, elevated serum level of VLDL, elevated plasma level of HbA1c, and decreased levels of HDL were observed in the diabetic untreated animals. Nigerian propolis decreased blood glucose level and serum level of VLDL but elevated HDL level. These changes were significant (P < 0.05). The levels of plasma HbA1c were also reduced in the propolis-treated groups, and the reduction was significant (P < 0.05). Conclusion: Nigerian propolis contains compounds exhibiting hypoglycemic, antihyperlipidemic, and HbA1c reducing activities. PMID:27366348

    Full Text Available Rice koji is considered a readily accessible functional food that may have health-promoting effects. We investigated whether white, yellow, and red koji have the anti-obesity effect in C57BL/6J mice fed a high-fat diet (HFD, which is a model for obesity. Mice were fed HFD containing 10% (w/w of rice koji powder or steamed rice for 4 weeks. Weight gain, epididymal white adipose tissue, and total adipose tissue weight were significantly lower in all rice koji groups than in the HFD-rice group after 4 weeks. Feed efficiency was significantly reduced in the yellow koji group. Blood glucose levels were significantly lower in the white and red koji groups with HOMA-R and leptin levels being reduced in the white koji group. White and red koji increased glucose uptake and GLUT4 protein expression in L6 myotube cells. These results showed that all rice koji have the anti-obesity or anti-diabetes effects although the mechanisms may differ depending on the type of rice koji consumed.

    High precision meters for blood glycemia are mandatory for monitoring glucose status in patients, avoiding both hypo- and hyper-glycemia. Health care providers routinely used in both out- and in-patients point-of-care measurements of glucose and ketone. These measurements, frequently used for medical decisions, are known to be less accurate than those performed in laboratories. Our aim was to evaluate, within the frame of an Assistance Publique-Hôpitaux de Paris (AP-HP) multicentric study, the performances of eight glucose and four ketone meters, either connected or non-connected to a laboratory software. Glucose meter accuracy, precision, correlation with plasma glucose determined in central laboratories and hematocrit interferences were determined according to the ISO 15197:2003 norm. The same norm was applied for the determination of accuracy, precision and recovery of ketone meters for B-hydroxybutyrate measurements. Among those meters, seven were considered as acceptable for glucose measurement and two for ketone measurement. Since all meters do not fit clinically relevant criteria, meters' performances have to be evaluated before use in clinical practice. Copyright © 2015 The Canadian Society of Clinical Chemists.

    The anti-diabetic activity of ginger powder (Zingiber officinale) has been recently promoted, with the recommendation to be included as one of the dietary supplements for diabetic patients. However, previous studies presented different results, which may be caused by degradation and metabolic changes of ginger components, gingerols, shogaols and paradols. Therefore, we prepared 10 ginger active components, namely 6-, 8-, 10-paradols, 6-, 8-, 10-shogaols, 6-, 8-, 10-gingerols and zingerone, and evaluated their anti-hyperglycemic activity. Among the tested compounds, 6-paradol and 6-shogaol showed potent activity in stimulating glucose utilization by 3T3-L1 adipocytes and C2C12 myotubes. The effects were attributed to the increase in 5' adenosine monophosphate-activated protein kinase (AMPK) phosphorylation in 3T3-L1 adipocytes. 6-Paradol, the major metabolite of 6-shogaol, was utilized in an in vivo assay and significantly reduced blood glucose, cholesterol and body weight in high-fat diet-fed mice.

    2007-03-01

    Selection of what blood glucose monitoring system to utilize has become an issue for physicians, diabetes educators, pharmacists, and patients. The field of competing makes and models of blood glucose monitoring systems has become crowded, with manufacturers touting improvements in accuracy, ease of use/alternate site options, stored results capacity, software evaluation tools, and/or price point. Personal interviews of 12 pharmacists from community and academic practice settings about monitor preference, as well as results from a national survey of pharmacist recommendations, were compared to actual wholesale sales data to estimate the impact of such recommendations on final monitor selection by the patient. Accu-Chek monitors were recommended 34.65% of the time and represented 28.58% of sales, with a success rate of 82.48% of being the monitor selected. OneTouch monitors had 27.72% of recommendations but represented 31.43% of sales, indicating possible patient brand loyalty or formulary preference for that product. FreeStyle(R) monitors came in third for pharmacist recommendations and were selected by the patient 61.68% of the time when recommended. The category of "other monitor" choices was selected 60.89% of the time by patients given those suggestions. Included in the "other monitor" category was the new disposable monitor marketed as the Sidekick. Based on sales data provided, the Sidekick made up 2.87% of "other monitor" category sales, representing 68% of the "other monitor" segment. While patients frequently follow pharmacist monitoring system suggestions, the ultimate deciding factor is most often the final out-of-pocket cost to the patient. As a result, cost of supplies often becomes the most important determining factor in final monitor selection at the patient level. If the patient cannot afford to perform the recommended daily testing intervals, all other determining factors and suggestions become moot.

    Diabetes is a condition in which the body either does not produce enough insulin, or does not properly respond to it. This causes the glucose level in blood to increase. An algorithm based on Integral High-Order Sliding Mode technique is proposed, which keeps the normal blood glucose level automatically releasing insulin into the blood. The system is highly insensitive to inevitable parametric and model uncertainties, measurement noises and small delays.

    It has been suggested that glucose levels ≥155 mg/dl at 1-h during an oral glucose tolerance test (OGTT) may predict development of type 2 diabetes and cardiovascular events among adults with normal glucose tolerance (NGT 1 h-high). Studies showed a link between increased blood viscosity and type 2 diabetes. However, whether blood viscosity is associated with dysglycemic conditions such as NGT 1 h-high, impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) is unsettled. 1723 non-diabetic adults underwent biochemical evaluation and OGTT. A validated formula based on hematocrit and total plasma proteins was employed to estimate whole blood viscosity. Subjects were categorized into NGT with 1 h glucose h-low), NGT-1 h-high, IFG and/or IGT. Hematocrit and blood viscosity values appeared significantly higher in individuals with NGT 1 h-high, IFG and/or IGT as compared to NGT 1 h-low subjects. Blood viscosity was significantly correlated with age, waist circumference, blood pressure, HbA1c, fasting, 1- and 2-h post-challenge insulin levels, total cholesterol and low-density lipoprotein, triglycerides, fibrinogen, white blood cell, and inversely correlated with high-density lipoprotein and insulin sensitivity. Of the four glycemic parameters, 1-h post-challenge glucose showed the strongest correlation with blood viscosity (β = 0.158, P h post-challenge plasma glucose. They also suggest that a subgroup of NGT individuals with 1-h post-challenge plasma >155 mg/dl have increased blood viscosity comparable to that observed in subjects with IFG and/or IGT.

    2012-03-01

    To identify the current status of scientific knowledge in fructo-oligosaccharides (FOS), non-conventional sugars that play an important role in glycemia control. We performed a search for scientific articles in MEDLINE and LILACS databases, from January 1962 to December 2011, using English/Portuguese key words: "blood glucose/glicemia", "prebiotics/prebióticos" and "dietary fiber/fibras na dieta". From an initial number of 434 references, some repeated, 43 references published from 1962 to 2011 were included in this study. The selected texts were distributed in three topics: (1) metabolism of FOS, (2) FOS and experimental studies involving glucose and (3) human studies involving glucose and FOS. Five studies have shown that the use of FOS reduces the fecal content and increases intestinal transit time. Experimental studies have shown that dietary supplementation with high doses (60 g/Kg) of propionate, a short-chain fatty acid decreased glycemia. The use of lower doses (3 g/kg) did not produce the same results. Study in subjects with diabetes type II showed that the addition of 8 grams of FOS in the diet for 14 days, caused a reduction in serum glucose. In another study with healthy subjects, there were no changes in glycemic control. This review demonstrates that consumption of FOS has a beneficial influence on glucose metabolism. The controversies appear to be due to inadequate methodological designs and/or the small number of individuals included in some studies.

  3. Non-invasive Blood Glucose Quantification Using a Hybrid Sensor

    Full Text Available Diabetes Mellitus is a group of metabolic diseases characterized by high blood sugar (glucose levels which result from defects in insulin secretion. It is very important for the diabetics and normal people to have a correct blood glucose level. The HbA1c test is the most preferred test by renowned doctors for glucose quantification. But this test is an invasive one. At present, there are many available techniques for this purpose but these are mostly invasive or minimally non-invasive and most of these are under research. Among the different methods available, the photo acoustic (PA methods provide a reliable solution since the acoustical energy loss is much less compared to the optical or other techniques. Here a novel framework is presented for blood glucose level measurement using a combination of the HbA1c test and a PA method to get an absolutely consistent and precise, non-invasive technique. The setup uses a pulsed laser diode with pulse duration of 5-15 ns and at a repetition rate of 10 Hz as the source. The detector setup is based on the piezoelectric detection. It consists of a ring detector that includes two double ring sensors that are attached to the ring shaped module that can be worn around the finger. The major aim is to detect the photo acoustic signals from the glycated hemoglobin with the least possible error. The proposed monitoring system is designed with extreme consideration to precision and compatibility with the other computing devices. The results obtained in this research have been studied and analyzed by comparing these with those of in-vitro techniques like the HPLC. The comparison has been plotted and it shows a least error. The results also show a positive drive for using this concept as a basis for future extension in quantifying the other blood components.

  4. In vivo blood glucose quantification using Raman spectroscopy.

    Jingwei Shao

    Full Text Available We here propose a novel Raman spectroscopy method that permits the noninvasive measurement of blood glucose concentration. To reduce the effects of the strong background signals produced by surrounding tissue and to obtain the fingerprint Raman lines formed by blood analytes, a laser was focused on the blood in vessels in the skin. The Raman spectra were collected transcutaneously. Characteristic peaks of glucose (1125 cm(-1 and hemoglobin (1549 cm(-1 were observed. Hemoglobin concentration served as an internal standard, and the ratio of the peaks that appeared at 1125 cm(-1 and 1549 cm(-1 peaks was used to calculate the concentration of blood glucose. We studied three mouse subjects whose blood glucose levels became elevated over a period of 2 hours using a glucose test assay. During the test, 25 Raman spectra were collected transcutaneously and glucose reference values were provided by a blood glucose meter. Results clearly showed the relationship between Raman intensity and concentration. The release curves were approximately linear with a correlation coefficient of 0.91. This noninvasive methodology may be useful for the study of blood glucose in vivo.

    The dose-response relationship between fasting blood glucose levels and risk of pancreatic cancer has been investigated, but the association between casual blood glucose levels and pancreatic cancer death has not been examined. We examined the association between casual and fasting blood glucose levels and death due to pancreatic cancer in Japanese. We performed a pooled analysis of the individual Japanese including 46,387 participants aged 40-79 years from ten cohorts. Participants were classified into five groups: low normal, middle normal, high normal, prediabetes (casual blood glucose 140-199 mg/dl, or fasting blood glucose 110-125 mg/dl), and diabetes (casual blood glucose ≥200 mg/dl, fasting blood glucose ≥126 mg/dl, or anti-diabetic drug use). Low normal, middle normal, and high normal were defined according to tertiles of casual or fasting normal blood glucose levels. Hazard ratios (HRs) and 95% confidence intervals (CIs) for pancreatic cancer mortality were estimated stratifying casual and fasting blood glucose by cohort-stratified Cox proportional hazards regression analysis, with low normal (casual blood glucose <94 mg/dl, or fasting blood glucose <90 mg/dl) as a reference. Fasting blood glucose showed a dose-response relationship with pancreatic cancer mortality (p for trend = 0.005). After adjusting for covariates, HRs (95% CIs) were 2.83 (1.18-6.76) for prediabetes and 3.96 (1.56-10.08) for diabetes. However, there were no significant associations with casual blood glucose. These tendencies were observed after the exclusion of participants who were censored for the first 5 years of follow-up. Fasting blood glucose is a better predictor of pancreatic cancer death than casual blood glucose.

    To explore the experiences of patients and professionals taking part in a randomised controlled trial (RCT) of blood glucose, blood pressure (BP) and weight telemonitoring in type 2 diabetes supported by primary care, and identify factors facilitating or hindering the effectiveness of the intervention and those likely to influence its potential translation to routine practice. Qualitative study adopting an interpretive descriptive approach. 23 patients, 6 nurses and 4 doctors who were participating in a RCT of blood glucose and BP telemonitoring. A maximum variation sample of patients from within the trial based on age, sex and deprivation status of the practice was sought. 12 primary care practices in Scotland and England. Data were collected via recorded semistructured interviews. Analysis was inductive with themes presented within an overarching thematic framework. Multiple strategies were employed to ensure that the analysis was credible and trustworthy. Telemonitoring of blood glucose, BP and weight by people with type 2 diabetes was feasible. The data generated by telemonitoring supported self-care decisions and medical treatment decisions. Motivation to self-manage diet was increased by telemonitoring of blood glucose, and the 'benign policing' aspect of telemonitoring was considered by patients to be important. The convenience of home monitoring was very acceptable to patients although professionals had some concerns about telemonitoring increasing workload and costs. Telemonitoring of blood glucose, BP and weight in primary care is a promising way of improving diabetes management which would be highly acceptable to the type of patients who volunteered for this study.

    Full Text Available Objectives: There is alarming rise in number of people with diabetes mellitus over these years. If glucose in saliva is linked to glucose in blood it can be used to detect diabetes mellitus at an early stage. The present study is undertaken with the aim to assess the correlation of salivary glucose level with blood glucose level in people with diabetes mellitus. Material and Methods: For investigations, 2 sets of samples of people with diabetes and the age and sex matched non-diabetic subjects were recruited. The salivary glucose was analyzed in unstimulated whole saliva samples using glucose oxidase method. Pearson’s correlation coefficient test was applied to assess the correlation between salivary glucose level and blood glucose level. Results: The significant (P < 0.05 positive correlation of salivary glucose level and fasting blood glucose level was observed in people with uncontrolled diabetes in both the sets of samples.Conclusions: Although study suggests some potential for saliva as a marker in monitoring of diabetes mellitus, there are many aspects that need clarification before we reach to a conclusion.

    2006-12-01

    Full Text Available Abstract Background The will to eat is a decision associated with conditioned responses and with unconditioned body sensations that reflect changes in metabolic biomarkers. Here, we investigate whether this decision can be delayed until blood glucose is allowed to fall to low levels, when presumably feeding behavior is mostly unconditioned. Following such an eating pattern might avoid some of the metabolic risk factors that are associated with high glycemia. Results In this 7-week study, patients were trained to estimate their blood glucose at meal times by associating feelings of hunger with glycemic levels determined by standard blood glucose monitors and to eat only when glycemia was Conclusion Subjects could be trained to accurately estimate their blood glucose and to recognize their sensations of initial hunger at low glucose concentrations. These results suggest that it is possible to make a behavioral distinction between unconditioned and conditioned hunger, and to achieve a cognitive will to eat by training.

    Our previous studies have raised the possibility that altered blood glucose levels may influence and/or be predictive of methamphetamine (METH) neurotoxicity. This study evaluated the effects of exogenous glucose and corticosterone (CORT) pretreatment alone or in combination with METH on blood glucose levels and the neural and vascular toxicity produced. METH exposure consisted of four sequential injections of 5, 7.5, 10, and 10 mg/kg (2h between injections) D-METH. The three groups given METH in combination with saline, glucose (METH+Glucose), or CORT (METH+CORT) had significantly higher glucose levels compared to the corresponding treatment groups without METH except at 3 h after the last injection. At this last time point, the METH and METH+Glucose groups had lower levels than the non-METH groups, while the METH+CORT group did not. CORT alone or glucose alone did not significantly increase blood glucose. Mortality rates for the METH+CORT (40%) and METH+Glucose (44%) groups were substantially higher than the METH (< 10%) group. Additionally, METH+CORT significantly increased neurodegeneration above all other treatments (≈ 2.5-fold in the parietal cortex). Thus, maintaining elevated levels of glucose during METH exposure increases lethality and may exacerbate neurodegeneration. Neuroinflammation, specifically microglial activation, was associated with degenerating neurons in the parietal cortex and thalamus after METH exposure. The activated microglia in the parietal cortex were surrounding vasculature in most cases and the extent of microglial activation was exacerbated by CORT pretreatment. Our findings implicate elevated blood levels of glucose and hyperthermia in METH-induced neurotoxicity, neurovascular damage, and lethality, and that acute elevation of CORT exacerbates both neurotoxicity and neuroinflammation.

    Diabetes, a typical lifestyle-related disease, is an important disease presenting risks of various complications such as retinopathy, kidney failure, and nervous neuropathy. To treat diabetes, regular and continual self-measurement of blood glucose concentrations is necessary to maintain blood glucose levels and to prevent complications. Usually, daily measurements are taken using invasive methods such as finger-prick blood sampling. Some non-invasive optical techniques have been proposed to reduce pain and infection risk, however, few practical techniques exist today. To realize highly accurate and practical measurement of blood glucose concentrations, the feasibility of a photoacoustic method using near-infrared light was evaluated. A photoacoustic signal from a solution of glucose in water (+0-5 g/dl) or equine blood (+0-400 mg/dl) was measured using a hydrophone (9 mm diameter) at 800-1800 nm wavelengths. We investigated the relation between the glucose solution concentration and the photoacoustic signal intensity or peak position of the received photoacoustic signal (i.e. speed of sound in solutions). Results show that the signal intensity and sound speed of the glucose solution increase with increased glucose concentration for wavelengths at which light absorbance of glucose is high. For quantitative estimation of the glucose solution concentration, the photoacoustic signal intensity ratio between two wavelengths, at which dependence of the signal intensity on glucose concentration is high and low, was calculated. Results confirmed that the signal intensity ratios increase linearly with the glucose concentration. These analyses verified the feasibility of glucose level estimation using photoacoustic measurement in the near-infrared region.

    Noninvasive monitoring of tissue optical properties in real time could significantly improve diagnostics and management of various diseases. Recently we proposed to use high- resolution Optical Coherence Tomography (OCT) technique for measurement of tissue scattering coefficient at the depth of up to 1mm. Our pilot studies performed in vitro and in vivo demonstrated that measurement of tissue scattering with this technique can potentially be applied for noninvasive monitoring of blood glucose concentration. High resolution and coherent photon detection of the OCT technique allowed detection of glucose-induced changes in the scattering coefficient. In this paper we report results of in vivo studies performed in dog, New Zealand rabbits, and first human subjects. OCT system with the wavelength of 1300 nm was used in our experiments. OCT signal slope was measured and compared with actual blood glucose concentration. Bolus glucose injections and glucose clamping administrations were used in animal studies. OCT signals were recorded form human subjects during oral glucose tolerance test. Results obtained form both animal and human studies show good correlation between slope of the OCT signals and actual blood glucose concentration measured using standard glucometesr. Sensitivity and accuracy of blood glucose concentrations monitoring with the OCT is discussed. Obtained result suggest that OCT is a promising technique for noninvasive monitoring of tissue analytes including glucose.

    Development of non-invasive techniques for glucose monitoring is crucial to improve glucose control and treatment adherence in patients with diabetes. Hereafter, Optical Coherence Tomography (OCT) may offer a good alternative for portable glucometers, since it uses light to probe samples. Changes in the object of interest can alter the intensity of light returning from the sample and, through it, one can estimate the sample's attenuation coefficient (μt) of light. In this work, we aimed to explore the behavior of μt of mouse's blood under increasing glucose concentrations. Different samples were prepared in four glucose concentrations using a mixture of heparinized blood, phosphate buffer saline and glucose. Blood glucose concentrations were measured with a blood glucometer, for reference. We have also prepared other samples diluting the blood in isotonic saline solution to check the effect of a higher multiple-scattering component on the ability of the technique to differentiate glucose levels based on μt. The OCT system used was a commercial Spectral Radar OCT with 930 nm central wavelength and spectral bandwidth (FWHM) of 100 nm. The system proved to be sensitive for all blood glucose concentrations tested, with good correlations with the obtained attenuation coefficients. A linear tendency was observed, with an increase in attenuation with higher values of glucose. Statistical difference was observed between all groups (p<0.001). This work opens the possibility towards a non-invasive diagnostic modality using OCT for glycemic control, which eliminates the use of analytes and/or test strips, as in the case with commercially available glucometers.

    The development of adequate mathematical models for blood glucose dynamics may improve early diagnosis and control of diabetes mellitus (DM). We have developed a stochastic nonlinear second order differential equation to describe the response of blood glucose concentration to food intake using continuous glucose monitoring (CGM) data. A variational Bayesian learning scheme was applied to define the number and values of the system's parameters by iterative optimisation of free energy. The model has the minimal order and number of parameters to successfully describe blood glucose dynamics in people with and without DM. The model accounts for the nonlinearity and stochasticity of the underlying glucose-insulin dynamic process. Being data-driven, it takes full advantage of available CGM data and, at the same time, reflects the intrinsic characteristics of the glucose-insulin system without detailed knowledge of the physiological mechanisms. We have shown that the dynamics of some postprandial blood glucose excursions can be described by a reduced (linear) model, previously seen in the literature. A comprehensive analysis demonstrates that deterministic system parameters belong to different ranges for diabetes and controls. Implications for clinical practice are discussed. This is the first study introducing a continuous data-driven nonlinear stochastic model capable of describing both DM and non-DM profiles.

    2016-01-01

    This book tackles the problem of overshoot and undershoot in blood glucose levels caused by delay in the effects of carbohydrate consumption and insulin administration. The ideas presented here will be very important in maintaining the welfare of insulin-dependent diabetics and avoiding the damaging effects of unpredicted swings in blood glucose – accurate prediction enables the implementation of counter-measures. The glucose prediction algorithms described are also a key and critical ingredient of automated insulin delivery systems, the so-called “artificial pancreas”. The authors address the topic of blood-glucose prediction from medical, scientific and technological points of view. Simulation studies are utilized for complementary analysis but the primary focus of this book is on real applications, using clinical data from diabetic subjects. The text details the current state of the art by surveying prediction algorithms, and then moves beyond it with the most recent advances in data-based modeling o...

    Optimal outcome of gestational diabetes mellitus (GDM) is directly related to glucose control of the mother. If prenatal vitamins cause a large glycemic excursion, then the best prenatal vitamin would be one that produces the lowest blood glucose. Nine GDM women participated in two, 8-day test periods. Each subject ingested one of six prenatal vitamin-mineral preparations, a placebo, or a sucrose capsule, in random order. Blood glucose was determined by the One Touch System at 0, 30, and 60 minutes. The sucrose capsule contained 1 g sucrose (equivalent to highest glucose/carbohydrate content of any prenatal vitamin). The placebo contained 1 g table salt in the same color capsule. Relative glycemic index (RGI, defined as the area under glucose curve for the test substance divided by the area under glucose curve for 1 g sucrose) and maximum rise of blood glucose above time 0 were calculated for each preparation. RGI was significantly elevated for all vitamins: TRN 3.86, Natalins Rx 3.00, Filibon Forte 2.16, Prenatal Formula 2.10, Materna 1.66, Placebo 1.33, Stuartnatal 1 + 1 1.16. Two thousand mg vitamin C (n = 4) resulted in an RGI of 1.37. In conclusion, ingestion of prenatal vitamins produces a rise in blood glucose greater than that seen following ingestion of sucrose equal to the carbohydrate content of prenatal vitamins. The cause of the blood glucose rise is not known, but it would appear prudent to prescribe a prenatal vitamin with a low RGI.

    We examined the relationships between 4 glycated protein assays and home blood glucose monitoring (HBGM) in 26 children with poorly-controlled insulin-dependent diabetes mellitus (IDDM) during a period of improved management. At 2 week intervals for 6 visits (12 weeks in total), HBGM records were collected and a blood sample was obtained for measurement of glycated proteins and glucose. Assays included glycated hemoglobin (GHb) and glycated serum proteins (GP) by boronate affinity chromatography, hemoglobin A1C by PolyCAT A high performance liquid chromatography (HAC) and fructosamine (FA). All 4 glycated protein levels declined significantly over the 12 week period. Significant correlations between the glycated proteins and HBGM were observed over 2 week intervals. None of the 4 assays were affected by the glucose level in the sample. Changes in mean HBGM readings over 2 week intervals were correlated with both FA and GP with wide prediction intervals. Over cumulative 2 week intervals, which may more accurately reflect longitudinal trends, all 4 glycated proteins were correlated with mean HBGM readings. At each cumulative interval, GHb and GP showed the largest variation with MBG, while FA showed the least variation with MBG. Our data indicate that of the 4 assays tested, FA has limited clinical values as compared to other glycated protein assays, whereas assays based on boronate affinity chromatography (GHb and GP) provide the most useful clinical indicators of short-term changes in glycemic control. The clinical utility of a new HPLC method for determination of glycated hemoglobins is also demonstrated.

    In recent years, many authors have investigated the possible antidiabetic effect of lactic acid bacteria. Lactobacillus species constitute a major part of the lactic acid bacteria group and have been found to exhibit beneficial effects on the development of diabetes and its complications. In the current study, we investigated the effects of newly characterised Bulgarian Lactobacillus strains, Lactobacillus brevis 15 and Lactobacillus plantarum 13, on blood glucose levels and body weight of rats fed a fructose-enriched diet. An experiment was conducted over a period of 8 weeks with 24 2-month-old Wistar rats randomly assigned to receive a standard diet (Con, control group), fructose-enriched diet (Fr group), standard diet with probiotics given twice a week (Pro group), and fructose-enriched diet with probiotics given twice a week (Pro+Fr group). At the end of the experimental period, a statistically significant increase in body weight was observed in all experimental groups (P<0.0001). The highest rise was seen in the fructose group (Fr, 169±19 g), followed by the Pro+Fr group (153±15 g), Pro group (149±13 g), and Con group (141±5 g). Moreover, the final blood glucose levels had risen significantly in the groups receiving fructose either without (Fr; P<0.0001) or with lactobacilli (Pro+Fr; P=0.002), while the rise was insignificant in the group of rats given probiotic supplementation only (Pro, P=0.071) and inexistent in the Con group (P=0.999). The highest elevation of blood glucose levels was observed in the Fr group (3.18 mmol/l), followed by the Pro+Fr group (2.00 mmol/l) whereas the Pro group showed the lowest levels (0.60 mmol/l). The results of our study suggest that the newly characterised Bulgarian Lactobacillus strains, L. brevis 15 and L. plantarum 13, could be considered as possible probiotics and might be able to prevent some metabolic disturbances.

    Blood glucose level is an important parameter for doctors to diagnose and treat diabetes. The Near-Infra-Red (NIR) spectroscopy method is the most promising approach and this involves measurement on the body skin. However it is noted that the skin temperature does fluctuate with the environmental and physiological conditions and we found that temperature has important influences on the glucose measurement. In-vitro and in-vivo investigations on the temperature influence on blood glucose measurement have been carried out. The in-vitro results show that water temperature has significant influence on water absorption. Since 90% of blood components are water, skin temperature of measurement site has significant influence on blood glucose measurement. Also the skin temperature is related to the blood volume, blood volume inside capillary vessels changes with skin temperature. In this paper the relationship of skin temperature and signal from the skin and inside tissue was studied at different finger temperatures. Our OGTT (oral glucose tolerance test) trials results show the laser signals follow the skin temperature trend and the correlation of signal and skin temperature is much stronger than the correlation of signal and glucose concentration. A finger heater device is designed to heat and maintain the skin temperature of measurement site. The heater is controlled by an electronic circuit according to the skin temperature sensed by a thermocouple that is put close to the measurement site. In vivo trials were carried out and the results show that the skin temperature significantly influences the signal fluctuations caused by pulsate blood and the average signal value.

Insulin resistance and dysregulated blood glucose control are established risk factors for microvascular complications and cardiovascular disease. Despite the recognition of diabetes as a major health issue and the availability of a growing number of medications designed to counteract its detrimental effects, real and perceived barriers remain that prevent patients from achieving optimal blood glucose control. The development and utilization of inhaled insulin as a novel insulin delivery system may positively influence patient treatment adherence and optimal glycemic control, potentially leading to a reduction in cardiovascular complications in patients with diabetes.Keywords: diabetes, inhaled insulin, cardiovascular disease, blood glucose

    Piatkowski, B; Voigt, J; Girschewski, H

    1977-12-01

    In an experiment using 24 high-yielding cows (3rd and 6th lactations), group II was fed sugar beet as carbohydrate source (2 kg DM per animal and day) for 4 weeks before and for 4 weeks after parturition, whilst group I was given the equivalent amount of dried spent beet pulp. Sugar beet feeding during the dry period caused the glucose level in the blood to rise significantly from 48 to 55 mg/100 ml. On the 21st day of lactation the glucose concentration in group II (27 mg) had declined more strongly than in group I (37 mg). Feeding large amounts of easily soluble carbohydrates during the dry period obviously inhibits gluconeogenesis during early lactation. The ketone body level of group II was found to rise to 14 mg/100 ml by the 21st day of lactation (group I--4 mg), a level indicative of ketosis. The ketogenous action (strong formation of butyric acid in the rumen) of sugar beet enhances this effect, too. The daily milk yield did not vary much coming to 26.8 and 27.8 kg in the control and in the experimental group, respectively. The results allow to conclude that feeding fresh sugar beet to high-yielding cows just before and shortly after parturition is not advisable.

  14. Measurement of tissue optical properties with optical coherence tomography: Implication for noninvasive blood glucose concentration monitoring

    Science.gov (United States)

    Larin, Kirill V.

    Approximately 14 million people in the USA and more than 140 million people worldwide suffer from diabetes mellitus. The current glucose sensing technique involves a finger puncture several times a day to obtain a droplet of blood for analysis. There have been enormous efforts by many scientific groups and companies to quantify glucose concentration noninvasively using different optical techniques. However, these techniques face limitations associated with low sensitivity, accuracy, and insufficient specificity of glucose concentrations over a physiological range. Optical coherence tomography (OCT), a new technology, is being applied for noninvasive imaging in tissues with high resolution. OCT utilizes sensitive detection of photons coherently scattered from tissue. The high resolution of this technique allows for exceptionally accurate measurement of tissue scattering from a specific layer of skin compared with other optical techniques and, therefore, may provide noninvasive and continuous monitoring of blood glucose concentration with high accuracy. In this dissertation work I experimentally and theoretically investigate feasibility of noninvasive, real-time, sensitive, and specific monitoring of blood glucose concentration using an OCT-based biosensor. The studies were performed in scattering media with stable optical properties (aqueous suspensions of polystyrene microspheres and milk), animals (New Zealand white rabbits and Yucatan micropigs), and normal subjects (during oral glucose tolerance tests). The results of these studies demonstrated: (1) capability of the OCT technique to detect changes in scattering coefficient with the accuracy of about 1.5%; (2) a sharp and linear decrease of the OCT signal slope in the dermis with the increase of blood glucose concentration; (3) the change in the OCT signal slope measured during bolus glucose injection experiments (characterized by a sharp increase of blood glucose concentration) is higher than that measured in

  15. The Impact of opium consumption on blood glucose, serum lipids and blood pressure, and related mechanisms

    Full Text Available AbstractAim: Substance abuse has become a universal crisisin our modern age. Among illegal substances, opium and its derivatives have been ranked second in terms of usage after cannabis in the world. In many Asian regions, the use of opium enjoys a high social acceptance; hence, some common people and even medical practitioners believe that opium lowers blood glucose and pressure and treat dyslipidemia. How much this belief is scientifically justified? Method: The results of available studies on both humans and animals searched in different search engines up to mid-2016 were integrated (77 articles. Upon the findings we try to offer a more transparent picture of the effects of opium on the mentioned factors along with the probable underlying mechanisms of its action. Results: Taken together, a variety of evidences suggest that the consumption of opium has no scientific justification for amendment of these biochemical variables. The mechanisms proposed so far for the action of opium in the three above disorders are summarized at the end of the article. Short term effects seems to be mostly mediated through central nervous system (neural and hormonal mechanisms, but long term effects are often due to the structural and functional alterations in some body organs. Conclusion: Although opium may temporarily reduce blood pressure, but it increases blood glucose and most of blood lipids. Moreover its long term use has negative impacts and thus it aggravates diabetes, dyslipidemia and hypertension. Accordingly, it is necessary to inform societies about the potential disadvantages of unauthorized opium consumption.

    The aim of this study was to determine if short-term intermittent treatments of high-energy diet have any stimulatory effects on ovarian function and metabolic status in goat. Cycling Shiba goats were divided into treatment (TG; n=6) and control (CG; n=6) groups. After the detection of ovulation (1st ovulation, Day 0) by ultrasonography, a high-energy diet (250% of maintenance) was fed to the TG from Day 12 to Day 15 (4 days) and from Day 18 to Day 21 (4 days). The high-energy diet comprised 1000 g hay-cubes and 300 g of concentrated feed/head/day (approximately 15 MJ of digestible energy/day). The CG was offered maintenance diet throughout the experiment. Transrectal ultrasound examinations were conducted every other day during the luteal phase and were conducted daily during the follicular phase. Blood samples were collected daily from Day -2 to 7 days after ovulation (2nd ovulation) following the nutritional treatment for analysis of follicle stimulating hormone (FSH), progesterone, oestradiol, glucose and insulin in plasma. Two wave-like rises in the concentrations of glucose and insulin appeared in response to the intermittent nutritional stimulus. Mean plasma concentrations of glucose and insulin were significantly (Pintermittent nutritional stimulus from the luteal phase increased the total number of ovulatory follicles and the ovulation rate in association with increasing plasma concentrations of glucose and insulin in goats.

    This study was designed to assess changes in glucose metabolism in rats administered single or repeated doses of MDMA. Two different experiments were performed: (1) A single-dose study with four groups receiving 20 mg/kg, 40 mg/kg, saline or heat, and (2) a repeated-dose study with two groups receiving three doses, at intervals of 2 h, of 5 mg/kg or saline. Rats were imaged using a dedicated small-animal PET scanner 1 h after single-dose administration or 7 days after repeated doses. Glucose metabolism was measured in 12 cerebral regions of interest. Rectal temperature and blood glucose were monitored. Peak body temperature was reached 1 h after MDMA administration. Blood glucose levels decreased significantly after MDMA administration. In the single-dose experiment, brain glucose metabolism showed hyperactivation in cerebellum and hypo-activation in the hippocampus, amygdala and auditory cortex. In the repeated-dose experiment, brain glucose metabolism did not show any significant change at day 7. These results are the first to indicate that MDMA has the potential to produce significant hypoglycaemia. In addition, they show that MDMA alters glucose metabolism in components of the motor, limbic and somatosensory systems acutely but not on a long-term basis. (orig.)

    Metabolic rate constants for blood glucose turnover were estimated based on the decay of [U-14C, 6-3H]glucose injected intravenously in genetically diabetic KK mice. Comparison was made with the rate constants similarly obtained with non-diabetic and streptozotocin-induced diabetic ICR mice. Recycling of blood glucose via the Cori cycle, as estimated from the difference in the decay rate between 14C and 3H, was more active in KK mice than in non-diabetic and diabetic ICR mice. The Cori cycle activity was reduced by beta-adrenergic blockade in KK mice and was enhanced by alpha-blockade in ICR mice. It is concluded that predominance of beta-adrenergic functions in KK mice is responsible for activation of the Cori cycle as one of the mechanisms for metabolic resistance to endogenous insulin.

    Loneliness has been shown to have direct effects on one's personal well-being. Specifically, a greater feeling of loneliness is associated with negative mental health outcomes, negative health behaviors, and an increased likelihood of premature mortality. Using the neuroendocrine hypothesis, we expected social inclusion to predict decreases in both blood glucose levels and low-density lipoproteins (LDLs) and increases in high-density lipoproteins (HDLs). Fifty-two healthy adults provided self-report data for social inclusion and blood samples for hematological tests. Results indicated that higher social inclusion predicted lower levels of blood glucose and LDL, but had no effect on HDL. Implications for theory and practice are discussed.

    To evaluate the alternative parameters to monitor glycemia in pregnant women with diabetes studying the relationship between fructosamine testing and self monitoring of blood glucose in pregnant women with diabetes. Serum fructosamine levels and the self monitoring of blood glucose over 14 days before the collection of fructosamine were evaluated in 47 diabetic pregnant women. Seventy-one fructosamine levels and 2,238 glucose measurements (CGs) were analysed. Levels of fructosamine correlated with high blood glucose index (HBGI) and the standard deviation of glycemias (r = 0.28; p = 0.021 and r = 0.26; p = 0.03, respectively). The comparison between the mothers of the newborns with appropriated or large birthweight and those who gave birth to small newborns for their gestational age (SGA) showed that the latter had a lower glycemic mean (105 vs. 114 and 119 mg/dL), a higher low blood glucose index (5.8 vs. 1.3 and 0.7) and a higher percentage of hyperglycemias (11 vs. 0 and 0%) even when the fructosamine falls within the reference values (242 vs. 218 and 213 μmol/l). The levels of fructosamine can be used as further parameter to aid self monitoring of blood glucose to evaluate hyperglycemias and glycemic variability, however, this can underestimate hypoglycemias in pregnant women carrying small-for-gestational age fetuses.

    The routine use of self-monitoring of capillary blood glucose by pregnant diabetic patients currently provides the basis for both clinical management and ongoing investigation. Strategies must therefore be developed to ensure that these data are reliable and accurately reported by patients and are not influenced by diverse socioeconomic levels or varied geographic locations. To explore this issue, we used glucose reflectance meters with a memory microchip capable of storing up to 440 consecutive blood glucose determinations. Two diverse groups of women from Texas and New York who had gestational diabetes performed self-monitoring of blood glucose from diagnosis until delivery. Both groups recorded their blood glucose results daily in a logbook. The reporting performance of all the participating subjects resulted in an actual compliance rate of 60% to 70% of testings required of the patients. Comparison of African-American, Mexican-American, and white populations revealed no significant differences in patient performance or compliance. Moreover, no differences were found between the groups at different geographic locations (New York, Texas) in patients' willingness and ability to comply with the regimen of self-monitoring blood glucose. These findings suggest that the use of memory reflectance meters, in conjunction with patient education and positive interaction between patient and care provider, will result in high patient compliance regardless of socioeconomic level or ethnic diversity.

    The objective was to assess whether pediatric risk factors predict cardiovascular disease (CVD), impaired fasting glucose (IFG) + type 2 diabetes mellitus (T2DM), and high blood pressure (HBP) in young adulthood. We performed a prospective follow-up of 909 public-parochial suburban schoolchildren first studied at ages 6 to 18 years and 26 years later at a mean age of 38 years. Pediatric triglycerides (TGs), blood pressure, low-density lipoprotein cholesterol, body mass index, and glucose above and high-density lipoprotein cholesterol below established pediatric cutoffs, along with race, cigarette smoking, family history of CVD, T2DM, and HBP, were assessed as determinants of young adult CVD, a composite variable including IFG + T2DM and HBP. By stepwise logistic regression, adult CVD (19 yes, 862 no) was associated with pediatric high TG (odds ratio [OR], 5.85; 95% confidence interval [CI], 2.3-14.7). High TG in pediatric probands with young adult CVD was familial and was associated with early CVD in their high-TG parents. Adult IFG + T2DM (114 yes, 535 no) was associated with parental T2DM (OR, 2.2; 95% CI, 1.38-3.6), high childhood glucose (OR, 4.43; 95% CI, 2-9.7), and childhood cigarette smoking (OR, 1.64; 95% CI, 1.03-2.61). Adult HBP (133 yes, 475 no) was associated with pediatric high body mass index (OR, 2.7; 95% CI, 1.7-4.3) and HBP (OR, 2.5; 95% CI, 1.5-4.3). Pediatric risk factors are significantly, independently related to young adult CVD, IFG + T2DM, and HBP. Identification of pediatric risk factors for CVD, IFG + T2DM, and HBP facilitates initiation of primary prevention programs to reduce development of adult CVD, IFG + T2DM, and HBP.

    Refractometry is the determination of the optical refractive index of a substance or a mixture of substances. It is a very sensitive method for the detection and quantification of dissolved analytes, but it is incapable of distinguishing between different analytes. The aim of this investigation was to determine the principle suitability of refractometry for the quantification of glucose (blood sugar) in blood and various blood fluids which can readily be obtained for medical diagnosis, in particular blood plasma, blood serum, and their ultrafiltrates. After the oral intake of freshly dissolved alpha-glucose, the in vivo blood contents of the alpha and beta anomers of glucose were found to be in an at least approximate equilibrium at all times. This observation is a prerequisite for a refractometrical determination of glucose due to the fact that both molecule forms have different refractive index increments. An assessment of the glucose content in untreated blood fluids was not possible, since no suitable relationship to the refractive index was found, most probably due to the influence of the many other substances present in blood on this parameter. However, after removal of certain macromolecules by ultrafiltration, value pairs showed a high level of correlation, providing the nominal molecular weight limit (cut-off) of the ultrafilter used possessed a maximum of 300 kDa. Besides macromolecules, the osmolality of the fluids undergoing measurement also proved to be a considerable interfering factor, particularly when values were outside the normal physiological range between 285 and 293 mmol/L. If a clinical application of this method is to be contemplated it is imperative (1) that blood cells are separated and removed, (2) that macromolecules present in plasma or serum are removed, e.g. by ultrafiltration, and (3) that beyond the results presented the influence of all small molecules other than glucose on the overall refractive index be determined and included in

    Full Text Available Artificial sweeteners, such as saccharin or cyclamic acid are synthetically manufactured sweetenings. Known for their low energetic value they serve especially diabetic and adipose patients as sugar substitutes. It has been hypothesized that the substitution of sugar with artificial sweeteners may induce a decrease of the blood glucose. The aim of this study was to determine the reliability of this hypothesis by comparing the influence of regular table sugar and artificial sweeteners on the blood glucose concentration. In this pilot-study 16 patients were included suffering from adiposity, pre-diabetes and hypertension. In the sense of a cross-over design, three test trials were performed at intervals of several weeks. Each trial was followed by a test free interval. Within one test trial each patient consumed 150 ml test solution (water that contained either 6 g of table sugar (“Kandisin” with sweetener free serving as control group. Tests were performed within 1 hr after lunch to ensure conditions comparable to patients having a desert. Every participant had to determine their blood glucose concentration immediately before and 5, 15, 30 and 60 minutes after the intake of the test solution. For statistics an analysis of variance was performed. The data showed no significant changes in the blood glucose concentration. Neither the application of sugar (F4;60 = 1.645; p = .175 nor the consumption of an artificial sweetener (F2.068;31.023 = 1.551; p > .05 caused significant fluctuations in the blood sugar levels. Over a time frame of 60 minutes in the control group a significant decrease of the blood sugar concentration was found (F2.457;36.849 = 4.005; p = .020 as a physiological reaction during lunch digestion.

    Studies indicate a lower occurrence of diabetes mellitus (DM) in patients with neurofibromatosis type 1 (NF1). Fasting blood glucose (FBG) level is the main criterion used to diagnose DM and glucose intolerance. Therefore, this study compared FBG level between adults with NF1 and non-NF1 controls. We selected clinical records of 57 out of 701 individuals attending the Neurofibromatosis Outpatient Reference Center of the Clinics Hospital of the Federal University of Minas Gerais in Brazil. The selected patients with NF1 were matched to non-NF1 controls selected from the Brazilian Longitudinal Study of Adult Health according to sex, age (range, 35–74 years) and BMI at a ratio of 1:3. In both groups, individuals with DM were excluded. Median FBG level in the NF1 group (86 mg/dl (range, 56–127 mg/dl)) was lower than that in the non-NF1 control group (102 mg/dl (range, 85–146 mg/dl)) (P<0.001). Prevalence of FBG level ≥100 mg/dl in the NF1 group (16%) was lower than that in the non-NF1 control group (63%) (P<0.05). The chance of a high FBG level was 89% lower in the NF1 group (odds ratio, 0.112; 95% CI, 0.067–0.188) (P<0.05). In conclusion, adults with NF1 showed a lower FBG level and a lower prevalence of high FBG level compared with non-NF1 controls. PMID:26631381

    Background The delivery of glucose from the blood to the brain involves its passage across the endothelial cells of the blood-brain barrier (BBB), which is mediated by the facilitative glucose transporter protein 1 (GLUT1), and then across the neural cell membranes, which is mediated by GLUT3. This study aimed to evaluate the dynamic influence of hyperglycemia on the expression of these GLUTs by measuring their expression in the brain at different blood glucose levels in a rat model of diabetes. This might help to determine the proper blood glucose threshold level in the treatment of diabetic apoplexy.Methods Diabetes mellitus was induced with streptozotocin (STZ) in 30 rats. The rats were randomly divided into 3 groups: diabetic group without blood glucose control (group DM1), diabetic rats treated with low dose insulin (group DM2),and diabetic rats treated with high dose insulin (group DM3). The mRNA and protein levels of GLUT1 and GLUT3 were assayed by reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry, respectively.Results Compared with normal control rats, the GLUT1 mRNA was reduced by 46.08%, 29.80%, 19.22% (P<0.01) in DM1, DM2, and DM3 group, respectively; and the GLUT3 mRNA was reduced by 75.00%, 46.75%, and 17.89% (P<0.01)in DM1, DM2, and DM3 group, respectively. The abundance of GLUT1 and GLUT3 proteins had negative correlation with the blood glucose level (P<0.01). The density of microvessels in the brain of diabetic rats did not change significantly compared with normal rats.Conclusions Chronic hyperglycemia downregulates GLUT1 and GLUT3 expression at both mRNA and protein levels in the rat brain, which is not due to the decrease of the density of microvessels. The downregulation of GLUT1 and GLUT3 expression might be the adaptive reaction of the body to prevent excessive glucose entering the cell that may lead to cell damage.

    This study suggests an approach for the comparison and evaluation of particular compartments with modest experimental setup costs. A glucose level prediction model was used to evaluate the compartment's glucose transport rate across the blood capillary membrane and the glucose utilization rate by the cells. The glucose levels of the blood, subcutaneous tissue, skeletal muscle tissue, and visceral fat were obtained in experiments conducted on hereditary hypertriglyceridemic rats. After the blood glucose level had undergone a rapid change, the experimenter attempted to reach a steady blood glucose level by manually correcting the glucose infusion rate and maintaining a constant insulin infusion rate. The interstitial fluid glucose levels of subcutaneous tissue, skeletal muscle tissue, and visceral fat were evaluated to determine the reaction delay compared with the change in the blood glucose level, the interstitial fluid glucose level predictability, the blood capillary permeability, the effect of the concentration gradient, and the glucose utilization rate. Based on these data, the glucose transport rate across the capillary membrane and the utilization rate in a particular tissue were determined. The rates obtained were successfully verified against positron emission tomography experiments. The subcutaneous tissue exhibits the lowest and the most predictable glucose utilization rate, whereas the skeletal muscle tissue has the greatest glucose utilization rate. In contrast, the visceral fat is the least predictable and has the shortest reaction delay compared with the change in the blood glucose level. The reaction delays obtained for the subcutaneous tissue and skeletal muscle tissue were found to be approximately equal using a metric based on the time required to reach half of the increase in the interstitial fluid glucose level. © 2013 Published by Elsevier Ltd.

    Full Text Available We consider the question of 30-min prediction of blood glucose levels measured by continuous glucose monitoring devices, using clinical data. While most studies of this nature deal with one patient at a time, we take a certain percentage of patients in the data set as training data, and test on the remainder of the patients; i.e., the machine need not re-calibrate on the new patients in the data set. We demonstrate how deep learning can outperform shallow networks in this example. One novelty is to demonstrate how a parsimonious deep representation can be constructed using domain knowledge.

    Romo-Cárdenas, G.; Sánchez-López, J. de D.; Luque, P. A.; Cosío-León, M.; Nieto-Hipólito, Juan I.; Vázquez-Briseño, Mabel

    For the last decade, several studies on mid-IR spectroscopy for blood glucose quantification have not considered the compounds involved in the glucose regulation mechanism, in which insulin plays an important role. This work shows how insulin overlaps in the same mid-IR region in which glucose is quantified. This optical absorption interference is an important factor to be considered for this type of studies, in the scope of whole blood modeling for spectroscopy applications and the possible use of computer based metrics.

    A high-fat diet (HFD) induces obesity and the associated increases in blood glucose and inflammation through changes in gut microbiota, endotoxemia, and increased gut permeability. To counteract this, researchers have suggested that the use of probiotics that suppress production of proinflammatory lipopolysaccharide (LPS). Here, we tested whether Lactobacillus sakei OK67, which inhibits gut microbiota LPS production selected from among the lactic acid bacteria isolated from kimchi, exerted antihypoglycemic or anti-inflammatory effects in HFD-fed mice. Mice were randomly divided into 2 groups and fed an HFD or a low-fat diet for 4 weeks. These groups were further subdivided; 1 subgroup was treated with L sakei OK67 and fed the experimental diet for 4.5 weeks, whereas the other subgroup was fed the experimental diet alone. L sakei OK67 treatment lowered HFD-elevated LPS levels in blood and colonic fluid and significantly decreased HFD-elevated fasting blood glucose levels and the area under the curve in an oral glucose tolerance test. L sakei OK67 treatment inhibited HFD-induced body and epididymal fat weight gains, suppressed HFD-induced tumor necrosis factor-α and interleukin-1β expression and nuclear factor-κB activation in the colon, and significantly increased HFD-suppressed interleukin-10 and tight junction protein expression in the colon. Oral administration of L sakei OK67 significantly downregulated HFD-induced expression of peroxisome proliferator-activated receptor γ, fatty acid synthase, and tumor necrosis factor-α in adipose tissue. In addition, L sakei OK67 treatment strongly inhibited nuclear factor-κB activation in LPS-stimulated peritoneal macrophages. We report that L sakei OK67 ameliorates HFD-induced hyperglycemia and obesity by reducing inflammation and increasing the expression of colon tight junction proteins in mice.

    We investigated in 30 healthy adults the glycemic index (GI) of five strawberry jams made from various sugar compositions. The jam containing the highest ratio of glucose showed a high GI, while that containing a high ratio of fructose, a jam made from polydextrose, showed a low GI. There was a high correlation (r=0.969, p=0.006) between the GI and the predicted GI calculated from the sugar composition of the jams. Moreover, the influence on postprandial blood glucose response after an intake of only 20 g of jam and one slice of bread with 20 g jam was measured in 8 healthy adults. The blood glucose level after an intake of 20 g of the high GI jam containing the high glucose ratio was higher than that of other jams at 15 min, but there was no significant difference after 30 min. Regardless of whether the GI was low or high, differences in the jams were not observed in the postprandial blood glucose level or the area under the curve after eating either one slice of bread (60 g) or one slice of bread with less than 20 g of jam.

    Lactose tolerance tests are used clinically to screen children and infants. It is assumed that absorption of a lactose challenge in infants would occur in a predictable pattern prior to weaning. Twenty-one infants from 3 to 12 months of age were studied. The maximum blood glucose rise over fasting levels ranged from 11.0 to 62.0 mg/100 ml; the mean was 32.6 mg/100 ml. Six infants had a maximum rise of less than 20 mg/100 ml. Eleven infants (52%) had a maximum rise of greater than 30 mg/100 ml. Signs of intolerance were not noted in any subject. Weight and length were normally disturbed. Results indicate the variance in glucose rise existing within a population of infants growing normally and consuming milk. Gastric emptying, digestion, and absorption may influence the blood glucose rise after a lactose test. Established glucose levels used as an index to lactose absorption in older children and adults may not accurately reflect lactase activity in infants.

    Background Hypertension, diabetes mellitus, and osteoporosis are important comorbidities commonly seen in postmenopausal women. The aim of the present study was to investigate the relationships between blood pressure, blood glucose, and bone mineral density (BMD) in postmenopausal Turkish women. Methods In this cross-sectional study, 270 consecutive patients who were admitted to an outpatient clinic with vasomotor symptoms and/or at least 1 year of amenorrhea were included. The patients were categorized into three groups according to their blood pressure and metabolic status as follows: normotensive, hypertensive nondiabetics, and hypertensive diabetics. The T- and z-scores of the proximal femur and lumbar vertebrae were measured with the dual-energy X-ray absorptiometry method to assess the BMD of the study groups. Results Lumbar vertebral T-scores (P<0.001), lumbar vertebral z-scores (P<0.003), and proximal femoral T-scores (P<0.001) were demonstrated to be significantly lower in the hypertensive diabetic group compared to the hypertensive nondiabetic and normotensive groups. Systolic blood pressure was significantly inversely correlated with lumbar vertebral T-scores (r=−0.382; P=0.001), lumbar vertebral z-scores (r=−0.290; P=0.001), and proximal femoral T-scores (r=−0.340; P=0.001). Moreover, diastolic blood pressure was significantly inversely correlated with lumbar vertebral T-scores (r=−0.318; P=0.001), lumbar vertebral z-scores (r=−0.340; P=0.001), and proximal femoral T-scores (r=−0.304; P=0.001). Hypertension (odds ratio [OR]: 2.541, 95% confidence interval [CI]: 1.46–3.48, P=0.003), diabetes mellitus (OR: 2.136, 95% CI: 1.254–3.678, P=0.006), and age (OR: 1.069, 95% CI: 1.007–1.163, P=0.022) were found to be significant independent predictors of osteopenia in a multivariate analysis, after adjusting for other risk parameters. Conclusion The present study is the first to evaluate the relationships between blood pressure, blood glucose

    To determine the glucose responses of diabetes mellitus type II subjects to fruits, four locally available fruits (containing 25 g of available carbohydrates per serving portion) of chico, mango, pineapple, and papaya were tested among ten type II diabetic subjects, using wheat bread as the control. Results of the in vivo test indicated that chico and mango had significantly lower (P ≤ 0.05) blood glucose areas compared to wheat bread. Chico and mango also had a much lower glycemic index (GI), 57 and 59, respectively, compared to pineapple, 73 and papaya, 86. Differences in glucose responses to fruits and their varying GI are attributed to the amount of fiber, type and amount of sugars found, presence of antinutrients, acidity and physical characteristics of the fruits when chewed. The high fiber content of chico (7.9%), its fructose content (5.3%), its grainy texture when chewed and the presence of antinutrients (saponin, sapotin and achrasaponin) may contribute to its slow digestion and absorption. The low GI and blood glucose response of mango may be because of its fructose content (3.0%), acidity content (malic, citric and tartaric) and its phytic acid content (0.03%). Furthermore, starch, which is a possible factor contributing to low GI, is present in chico (0.8%) and mango (0.3%). Pineapple and papaya, the test fruits that elicited higher blood glucose responses and GI, have much lower fiber contents, less acids and contain glucose and sucrose sugars.

    Near infrared (NIR) has prospectively applied in non-invasive blood glucose measurement due to glucose absorption among the 1.0-2.5m spectral bands. However, this significant technology is hard to be developed because of other blood components and low signal-to-noise ratio (SNR). In this work, we presented a non-invasive glucose measurement system using Fourier transform spectrometer which will work in fingertips or other human body tissues. A refrigerated InGaAs detector with high quantum efficiency performing well in the range of 1.0-1.7μm wavelength is used to acquire transmissive radiation. Preliminary experiment investigations were set up to test glucose levels of aqueous solutions with different concentrations. The analytical modeling of the interferogram data is based on arithmetic Fourier transform and supported by the curvilineal characterization. Experimental results show the variation of light intensity among different glucose concentrations and emphasize the obvious absorption of glucose in NIR wave-range. This study confirms the suitability that NIR can be developed in non-invasive glucose measurement.

    Genome-wide association studies (GWAS) have successfully identified genetic loci associated with glycemic traits. However, characterizing the functional significance of these loci has proven challenging. We sought to gain insights into the regulation of fasting insulin and fasting glucose through the use of gene expression microarray data from peripheral blood samples of participants without diabetes in the Framingham Heart Study (FHS) (n = 5,056), the Rotterdam Study (RS) (n = 723), and the InCHIANTI Study (Invecchiare in Chianti) (n = 595). Using a false discovery rate q fasting glucose and 433 transcripts associated with fasting insulin levels after adjusting for age, sex, technical covariates, and complete blood cell counts. Among the findings, circulating IGF2BP2 transcript levels were positively associated with fasting insulin in both the FHS and RS. Using 1000 Genomes-imputed genotype data, we identified 47,587 cis-expression quantitative trait loci (eQTL) and 6,695 trans-eQTL associated with the 433 significant insulin-associated transcripts. Of note, we identified a trans-eQTL (rs592423), where the A allele was associated with higher IGF2BP2 levels and with fasting insulin in an independent genetic meta-analysis comprised of 50,823 individuals. We conclude that integration of genomic and transcriptomic data implicate circulating IGF2BP2 mRNA levels associated with glucose and insulin homeostasis. © 2016 by the American Diabetes Association.

    Because of the metabolism of serum glucose in collection tubes containing blood samples, serum glucose levels may be found to decrease over time. Several types of collection tubes have been designed to, at least partially, block glucose metabolism by red blood cells in blood collection tubes that may not be analyzed immediately after blood collection. These include red-top collection tubes with serum separator, grey-top tubes with a fluoride glycolysis inhibitor, and heparin-containing green-top tubes which prevent clot formation. As part of a quality assurance project, we investigated whether glucose levels differed in the three tube types from each of 18 volunteers on a prolonged standing of 4 hours. We then determined the glucose concentrations of all three tubes from each of the 18 volunteers. We used refrigerated samples over a five-day period to determine if the initial values were reproducible. Surprisingly, after standing for four hours at room temperature, we found that the glucose levels in the three tubes from each volunteer were statistically indistinguishable from one another using the two-tailed paired t-test. Also, a linear regression analysis showed that the values of glucose for the three pairs of two tube types were closely correlated with one another, with correlation coefficients of >0.97, slopes close to 1, and Y-intercepts close to 0. These results suggest that blood collection in any of these tubes will render similar values for serum glucose even after standing for four hours. The tubes were then refrigerated at 4°C and re-analyzed after another six hours and then once per day for the next four days. Beginning at the first day at the six-hour determination, the glucose levels in the red- and grey-top tubes were statistically indistinguishable from one another but not in the red- and green-top tubes and in the grey- and green-top tubes. This was due to a steady decrease in the glucose levels in the green-top tubes. The glucose levels in the

    The performance of Blood Glucose Monitoring System (BGMS) is critical as the information provided by the system guide the patient or health care professional in making treatment decisions. However, besides evaluating accuracy of the BGMS in laboratory setting, it is equally important that the intended users (healthcare professionals and patients) should be able to achieve blood glucose measurements with similar level of high accuracy. To assess the performance of EXIMO™ (Meril Diagnostics Pvt. Ltd., Vapi, Gujarat, India) BGMS as per International Organization for Standardization (ISO) 15197:2013 section 8 user performance criteria. This was a non-randomized and post-marketing study conducted at a tertiary care centre of India. A total of 1005 patients with diabetes themselves performed fingertip blood glucose measurement using EXIMO™ BGMS. Immediately after capillary blood glucose measurement using the blood glucose monitoring system, venous blood sample from each patient was obtained by a trained technician which was assessed by reference laboratory method- Cobas Integra 400 plus (Roche Instrument Centre, Rotkreuz, Switzerland). All the blood glucose measurements assessed by EXIMO™ were compared with laboratory results. Performance of the system was assessed as per ISO 15197:2013 criteria using Bland-Altman plot, Parkes-Consensus Error Grid (CEG) and Surveillance Error Grid analyses (SEG). A total of 1005 patients participated in the study. Average age of the patients was 44.93±14.65 years. Evaluation of capillary fingertip blood glucose measurements demonstrated that 95.82% measurements fulfilled ISO 15197:2013 section 8 user performance criteria. All the results lie within clinically non-critical zones; Zone A (99.47%; n=1000) and Zone B (0.53%; n=05) of the CEG analysis. As per SEG analysis, majority of the results fell within "no-risk" zone (risk score 0 to 0.5; 90.42%). The result of the study confirmed that intended users are able to obtain accurate

    Intensive care unit (ICU) blood glucose control algorithms were reviewed and analyzed in the context of linear systems theory and classical feedback control algorithms. Closed-loop performance was illustrated by applying the algorithms in simulation studies using an in silico model of an ICU patient. Steady-state and dynamic input-output analysis was used to provide insight about controller design and potential closed-loop performance. The proportional-integral-derivative, columnar insulin dosing (CID, Glucommander-like), and glucose regulation for intensive care patients (GRIP) algorithms were shown to have similar features and performance. The CID strategy is a time-varying proportional-only controller (no integral action), whereas the GRIP algorithm is a nonlinear controller with integral action. A minor modification to the GRIP algorithm was suggested to improve the closed-loop performance. Recommendations were made to guide control theorists on important ICU control topics worthy of further study.

    Therapeutically, the closed-loop blood glucose-insulin regulation paradigm via a controllable insulin pump offers a potential solution to the management of diabetes. However, the development of such a closed-loop regulatory system to date has been hampered by two main issues: 1) the limited knowledge on the complex human physiological process of glucose-insulin metabolism that prevents a precise modeling of the biological blood glucose control loop; and 2) the vast metabolic biodiversity of the diabetic population due to varying exogneous and endogenous disturbances such as food intake, exercise, stress, and hormonal factors, etc. In addition, current attempts of closed-loop glucose regulatory techniques generally require some form of prior meal announcement and this constitutes a severe limitation to the applicability of such systems. In this paper, we present a novel intelligent insulin schedule based on the pseudo self-evolving cerebellar model articulation controller (PSECMAC) associative learning memory model that emulates the healthy human insulin response to food ingestion. The proposed PSECMAC intelligent insulin schedule requires no prior meal announcement and delivers the necessary insulin dosage based only on the observed blood glucose fluctuations. Using a simulated healthy subject, the proposed PSECMAC insulin schedule is demonstrated to be able to accurately capture the complex human glucose-insulin dynamics and robustly addresses the intraperson metabolic variability. Subsequently, the PSECMAC intelligent insulin schedule is employed on a group of type-1 diabetic patients to regulate their impaired blood glucose levels. Preliminary simulation results are highly encouraging. The work reported in this paper represents a major paradigm shift in the management of diabetes where patient compliance is poor and the need for prior meal announcement under current treatment regimes poses a significant challenge to an active lifestyle.

In critical patients, under conditions that cause an increase in metabolic state and level of stress, there occurs considerable difference in glucose levels between capillary and venous measurements. This study aimed to investigate the comparability of capillary and venous glucose values, according to the perfusion index level obtained with the Masimo Radical-7® device, in critical patients aged 18 years and over.Method: We conducted this prospective and observational study in the emergency department of the Eskisehir Osmangazi University hospital between November 3, 2008 and February 2, 2009.Results: The blood glucose of 300 critical patients was checked by finger stick in the emergency unit. The participants with normal vital signs had perfusion index between 0 and 5; the results obtained by the two methods were more consistent for perfusion index values of 6 and over. The results were most consistent in aged participants with normal vital sign findings and low perfusion index and in young patients with high perfusion index. In the cases where at least one of the vital signs was abnormal, the glucose values obtained by the two methods were more consistent when the perfusion index was 6 or over. In this group, independently from the perfusion index value, the consistency was higher in younger patients compared with aged patients.Conclusion: In the emergency department, perfusion index value measured by Masimo Radical-7 and capillary blood glucose levels can serve in blood sugar management in

    The number of diabetics is rapidly growing every day in all parts of the world. By the year 2010, the number of patients suffering from diabetes had amounted to more than 230 million people, which is estimated as 3.5% of the whole world adult population [1]. According to expert forecasts, this number is projected to double by the year 2025, which is going to be 7% of whole Earth population. It was calculated that every 10 seconds someone in the world dies due to diabetes and its complications, which is 3 million people per year. The average life expectancy of children with diabetes is less than 28.3 years of onset. Diabetes is considered to be the fourth most common cause of death in industrialized countries. Vascular complications due to diabetes cause early disability and high mortality. Mortality from heart diseases and strokes is 2-3 times more likely for patients suffering from diabetes, whereas blindness, nephropathy and lower limbs gangrene happen respectively 10, 12-15 times, and almost 20 times more often for diabetics than general population. The number and strength of complications depend directly on the blood glucose level control quality. At the moment, the blood glucose level measurements are performed by glucometers [2,3]. This method requires that a patient makes a finger puncture for every measurement. About five punctures per day should be done for proper glucose monitoring, which is about 1,800 punctures per year. Besides, each measurement by glucometer requires a distinct test strip. Expenses for 1,800 test strips could be estimated as about 450 euros per year. It is also necessary to take into account that each puncture has a risk of blood poisoning. Using non-invasive techniques for glucose level control could reduce the amount of possible risky manipulations by 1800 per year. Moreover, it is worth mentioning that only eight of ten fingers are suitable for puncturing, and the constant skin damage which cannot be avoided is quite annoying for

    Full Text Available OBJECTIVE: Numerous recent studies suggest that abnormal intracellular calcium concentration ([Ca2+]i is a common defect in diabetic animal models and patients. Abnormal calcium handling is an important mechanism in the defective pancreatic β-cell function in type 2 diabetes. T-type Ca2+ channel antagonists lower blood glucose in type 2 diabetes, but the mechanism remains unknown. METHODS: We examined the effect of the Ca2+ channel antagonist mibefradil on blood glucose in male db/db mice and phenotypically normal heterozygous mice by intraperitoneal injection. RESULTS: Mibefradil (15 mg/kg, i.p., b.i.d. caused a profound reduction of fasting blood glucose from 430.92±20.46 mg/dl to 285.20±5.74 mg/dl in three days. The hypoglycemic effect of mibefradil was reproduced by NNC 55-0396, a compound structurally similar to mibefradil but more selective for T-type Ca2+ channels, but not by the specific L-type Ca2+ channel blocker nicardipine. Mibefradil did not show such hypoglycemic effects in heterozygous animals. In addition, triglycerides, basal insulin and food intake were significantly decreased by mibefradil treatment in the db/db mice but not in the controls. Western blot analysis, immunohistochemistry and immunofluorescence staining showed a significantly increased expression of T-type Ca2+ channel α-subunits Cav3.1 and Cav3.2 in liver and brain tissues from db/db mice compared to those from heterozygous animals. CONCLUSIONS: Collectively, these results suggest that T-type Ca2+ channels are potential therapeutic targets for antidiabetic drugs.

    2012-09-01

    Considering the importance of glucose as a brain substrate, the postprandial rate of glucose delivery to the blood could be expected to affect cognitive functions. The purpose was to evaluate to what extent the rate of glucose absorption affected measures of cognitive performance in the postprandial period. In addition, cognitive performance was evaluated in relation to individual glucoregulation. A white wheat bread (WWB) enriched with guar gum (G-WWB) with the capacity to produce a low but sustained blood glucose net increment was developed. The G-WWB was evaluated in the postprandial period after breakfast with respect to effects on cognitive function (working memory and selective attention (SA)) in 40 healthy adults (49-71 years, body mass index 20-29 kg/m(2)), using a high glycaemic index WWB for comparison in a randomised crossover design. The G-WWB improved outcome in the cognitive tests (SA test) in the later postprandial period (75-225 min) in comparison with the WWB (Pcognitive tests compared with subjects with worse glucoregulation (Pcognitive performance were observed with the G-WWB in the late postprandial period. The positive effect is suggested to emanate from improved insulin sensitivity, possibly in a combination with an enhanced neural energy supply. The results highlight the importance of carbohydrate foods that induces a low but sustained blood glucose profile in enhancing postprandial cognitive functions.

    Full Text Available Abnormal deposition of neuriticplaques is the uniqueneuropathological hallmark of Alzheimer's disease (AD.Amyloid β protein (Aβ, the major component of plaques, is generated from sequential cleavage of amyloidβ precursor protein (APP by β-secretase and γ-secretase complex. Patients with diabetes mellitus (DM, characterized by chronic hyperglycemia,have increased risk of AD development.However, the role of high blood glucose in APP processing and Aβ generation remains elusive. In this study, we investigated the effect of high glucose on APP metabolism and Aβ generation in cultured human cells. We found that high glucose treatment significantly increased APP protein level in both neuronal-like and non-neuronal cells, and promoted Aβ generation. Furthermore, we found that high glucose-induced increase of APP level was not due to enhancement of APP gene transcription but resulted from inhibition of APP protein degradation. Taken together, our data indicated that hyperglycemia could promote AD pathogenesis by inhibiting APP degradation and enhancing Aβ production. More importantly, the elevation of APP level and Aβ generation by high glucose was caused by reduction of APP turnover rate.Thus,our study provides a molecular mechanism of increased risk of developing AD in patients withDMand suggests thatglycemic control might be potentially beneficial for reducing the incidence of AD in diabetic patients and delaying the AD progression.

    significant interdevice difference was found. After stratification of the serum blood glucose values into two groups, below and above 180 mg/dL, the variance found for the glucose meter OneTouch SureStep was statistically greater (P = 0.03 in relation to the serum glucose levels above 180 mg/dL, which was not the case with the glucose meters MediSense Optium (P = 0.06 and Optium Xceed (P = 0.12. The percentage of capillary blood glucose values showing a variation of less than 20% compared with serum values was 64.94% for OneTouch SureStep, 47.83% for Medisense Optium, and 51.61% for Optium Xceed, when serum glucose was greater than 75 mg/dL.Conclusion: The glucose meters tested showed an adequate interdevice correlation in their capillary glucose readings, in addition to correlating with the serum glucose values (ie, if a blood glucose reading is high or low in one test, it is likely to be respectively high or low in another. The means for the capillary blood glucose readings, however, were significantly different from the mean serum glucose. When serum glucose was above 180 mg/dL, there was a greater variance in the capillary measurements on the glucose meter OneTouch SureStep, with less correlation with the serum blood glucose (P < 0.05, which did not occur significantly with the two other glucose meters. On the other hand, OneTouch SureStep had the highest accuracy in relation to serum glucose when the whole sample of serum glucose values above 75 mg/dL was analyzed, considering a variation of less than 20% in the measurements. The three glucose meters provide readings that correlate with the serum glucose values of hospitalized patients. However, one should bear in mind that capillary measurements quite often show more than a 20% variation in relation to serum glucose values, and caution should be exercised in interpreting the readings when serum glucose levels are elevated.Keywords: capillary blood glucose, serum glucose, glucose meters, hospitalized patients

    To explore the correlation between resting heart rate (RHR) and blood glucose level in elderly patients with coronary heart disease (CHD) complicated by diabetes mellitus. Between April and July, 2011, a total of 1336 outpatients over 60 years of age recruited from 165 hospitals were asked to complete a questionnaire and received blood glucose and RHR examination. According to baseline RHR, the patients were divided into 3 groups with HRH blood glucose control rate. HbA1c levels in the total, male and female patients differed significantly among the 3 groups (F=15.436, 15.436, and 24.270, respectively, PBlood glucose control rate in the total, male and female patients also differed significantly among the 3 groups (χ(2)=13.471, 6.752, and 6.522, respectively, Pblood glucose control failure of 1.99 (95% CI: 1.23-2.37, Pblood glucose level, and an increased RHR is associated with an increased risk of poor blood glucose control. Rigorous RHR control in such high-risk patients may prove beneficial for both blood glucose control and secondary prevention of CHD.

    Full Text Available Blood glucose levels are affected by many factors including the type of foods consumed, processing technology and cooking method. Hormone insulin lowers blood glucose to its constant level, while glucagon, growth hormone, adrenalin and glucocorticoids have the opposite effect. High steepness of the blood glucose level rise after meals may be unfavourable for the organism. Sugars are transferred into the blood at different speeds according to the type of food. Therefore the aim of this study was to confirm experimentally the effect of food on blood glucose levels in men and women of different ages. Two types of low, medium and high-glycaemic index (GI foods were given to 4 men and 4 women of different age (from 35 to 65 years. All volunteers were healthy, slightly overweight, and without any regular sporting activity. None of them had any idea about their daily carbohydrates consumption and what the term glycaemic index meant. The volunteers came to the GI determination fasted in the morning. Their rise in blood glucose level was monitored by glucometer before the meal and after 1 and 2 hours of the consumption of baked potatoes (GI 85, white bread bun (GI 70, boiled potatoes (GI 64, rye bread (GI 62, potato dumplings (GI 52 and white cooked spaghetti (GI 41. Fasting blood sugar levels of volunteers highly depended on their age (p <0.0001 and gender (p <0.0001. The blood glucose values increased with age and were higher in men than in women. Significant influence of food GI on blood glucose levels in both men and women in all the age categories was observed (p <0.0001. An interaction between age and gender was also statistically highly significant (p <0.0001. One hour after consuming food the blood glucose values were significantly different from the values of fasting (p = 0.0035. The differences of these values did not depend on the age (p = 0.0574 and sex (p = 0.8256 of volunteers, but there was a significant difference on the GI value of food

    This pilot study examined the effects of freeze-dried mango (Mangifera indica L.) supplementation on anthropometrics, body composition, and biochemical parameters in obese individuals. Twenty obese adults (11 males and 9 females) ages 20- to 50-years old, received 10 g/day of ground freeze-dried mango pulp for 12 weeks. Anthropometrics, biochemical parameters, and body composition were assessed at baseline and final visits of the study. After 12 weeks, mango supplementation significantly reduced blood glucose in both male (−4.45 mg/dL, P = 0.018) and female (−3.56 mg/dL, P = 0.003) participants. In addition, hip circumference was reduced in male (−3.3 cm, P = 0.048) but not in female participants. However, there were no significant changes in body weight or composition in either gender. Our findings indicate that regular consumption of freeze-dried mango by obese individuals does not negatively impact body weight but provides a positive effect on fasting blood glucose.

    Full Text Available We examined the tracking of blood glucose, the development of prediabetes, and estimated their genetic contributions in a prospective, healthy, rural Chinese twin cohort. This report includes 1,766 subjects (998 males, 768 females aged 6-21 years at baseline who completed a 6-year follow-up study. Oral glucose tolerance test was performed for all subjects at both baseline and follow-up. We found that subjects with low fasting plasma glucose (FPG or 2 h post-load glucose (PG levels at baseline tended to remain at the low level at follow-up. Subjects in the top tertile of baseline plasma glucose tended to have a higher risk of developing prediabetes at follow-up compared to the low tertile: in males, 37.6% vs. 27.6% for FPG and 37.2% vs. 25.7% for 2hPG, respectively; in females, 31.0% vs. 15.4% for FPG and 28.9% vs. 15.1% for 2 h PG, respectively. Genetic factors explained 43% and 41% of the variance of FPG, and 72% and 47% for impaired fasting glucose for males and females, respectively; environmental factors substantially contribute to 2hPG status and impaired glucose tolerance. In conclusion, in this cohort of healthy rural Chinese children and adolescents, we demonstrated that both FPG and 2hPG tracked well and was a strong predictor of prediabetes. The high proportion of children with top tertile of blood glucose progressed to prediabetes, and the incidence of prediabetes has a male predominance. Genetic factors play more important role in fasting than postload status, most of which was explained by unique environmental factors.

    Full Text Available Abstract Background Methamphetamine (METH, an addictive psycho-stimulant drug with euphoric effect is known to cause neurotoxicity due to oxidative stress, dopamine accumulation and glial cell activation. Here we hypothesized that METH-induced interference of glucose uptake and transport at the endothelium can disrupt the energy requirement of the blood-brain barrier (BBB function and integrity. We undertake this study because there is no report of METH effects on glucose uptake and transport across the blood-brain barrier (BBB to date. Results In this study, we demonstrate that METH-induced disruption of glucose uptake by endothelium lead to BBB dysfunction. Our data indicate that a low concentration of METH (20 μM increased the expression of glucose transporter protein-1 (GLUT1 in primary human brain endothelial cell (hBEC, main component of BBB without affecting the glucose uptake. A high concentration of 200 μM of METH decreased both the glucose uptake and GLUT1 protein levels in hBEC culture. Transcription process appeared to regulate the changes in METH-induced GLUT1 expression. METH-induced decrease in GLUT1 protein level was associated with reduction in BBB tight junction protein occludin and zonula occludens-1. Functional assessment of the trans-endothelial electrical resistance of the cell monolayers and permeability of dye tracers in animal model validated the pharmacokinetics and molecular findings that inhibition of glucose uptake by GLUT1 inhibitor cytochalasin B (CB aggravated the METH-induced disruption of the BBB integrity. Application of acetyl-L-carnitine suppressed the effects of METH on glucose uptake and BBB function. Conclusion Our findings suggest that impairment of GLUT1 at the brain endothelium by METH may contribute to energy-associated disruption of tight junction assembly and loss of BBB integrity.

    2016-05-01

    Full Text Available Background: Lifestyle changes, particularly dietary intake, had resulted in increasing trends of type-2 diabetes mellitus worldwide. However, dietary intake is diverse across country contexts. This study aimed to compare the dietary intake, food patterns, and blood glucose among middle-aged adults living in urban and suburban areas in Mandalay city, Myanmar, and explore their relationships. Methods: A cross-sectional community-based study was conducted during June–November 2014. Adults aged 35–64 were randomly selected and requested to record all food they ate in a 4-day diary. Fasting and 2-hour postprandial blood glucose values were measured over two consecutive days. Dietary intakes were calculated in terms of energy, macronutrients, glycemic index, and glycemic load, and food patterns were identified by factor analysis. The relationships between food pattern, dietary intake, and blood glucose were assessed. Results: Of 440 participants, dietary intake between urban and suburban residents was significantly different. Six food patterns were identified. There was no difference in fasting and 2-hour postprandial blood glucose between urban and suburban residents, but a strong correlation between fasting blood glucose and 2-hour postprandial blood glucose was found (correlation coefficient=0.8. Identification of abnormal blood glucose status using original fasting and converted 2-hour postprandial values showed substantial agreement (prevalence-adjusted bias-adjusted Kappa= 0.8. Relationships between food patterns and blood glucose or abnormal blood glucose status were not found. Conclusion: Food patterns were associated with dietary intake, not with abnormal blood glucose status. Two-hour postprandial blood glucose was highly correlated with fasting blood glucose and may be used for identifying abnormal blood glucose status.

    The purpose of this study was to examine the association between self-monitoring of blood glucose (SMBG) and problem-solving skills in response to detected hyperglycemia and hypoglycemia among patients with type 2 diabetes. Data were obtained from the American Association of Diabetes Educators Outcome System, implemented in 8 diabetes self-management education programs in western Pennsylvania. SMBG was measured by asking patients how often they checked, missed checking, or checked blood glucose later than planned. Problem-solving skill was measured by asking how often they modified their behaviors after detecting high or low blood glucose. Most patients checked their blood glucose at least once per day. However, when blood glucose was high or low, many of them reported doing nothing, and only some of them resolved the problem. There were significant associations between self-monitoring of blood glucose and problem-solving skills for hyperglycemia and hypoglycemia, after controlling for age, gender, ethnicity, education, and time since diagnosis. Patients reported poor problem-solving skills when detecting hyperglycemia and hypoglycemia via SMBG. Patients need to learn problem-solving skills along with SMBG training to achieve glycemic control.

  7. COMPARATIVE STUDY OF GLUCOMETER AND LABORATORY GLUCOSE OXIDASE METHOD FOR THE ESTIMATION OF BLOOD GLUCOSE LEVELS IN NEONATES

    Directory of Open Access Journals (Sweden)

    Harish

    2015-02-01

    Full Text Available INTRODUCTION : Hypoglycemia is one of the most common metabolic problems encountered in neonates. Hypoglycemia in neonates can be symptomatic and asymptomatic. Hypoglycemia is known to be associated with brain dysfunction and neuromotor developmental retardation. The gl ucose oxidase method used in the laboratory for determining the blood glucose concentration is precise and specific for glucose. As it is usually performed in the main laboratory, the results are not available quickly enough for timely appropriate manageme nt. The glucometers are often used for blood glucose estimation in NICU. Many studies have shown that their results co - relate well with the laboratory measured glucose levels in the normoglycemic and hyperglycemic range but are not satisfactory in the lowe r range. OBJECTIVES: This is a prospective study done to determine the efficacy of glucometer in estimation of blood glucose levels in neonates in comparison with the laboratory values. METHOD S : 250 neonates admitted in NICU, KIMS hospital, Bangalore with varied symptomatology were enrolled in this study. Blood glucose estimation was done by glucometer and laboratory method using the same venous sample at the time of admission. For the last 50 cases glucometer estimation of capillary blood was also done. St atistical analysis was done by using Pearson correlation. Hypoglycemia was defined as blood glucose level 45mg%[0.756] and when the value is <45mg%, there is just a moderate correlation[0.417] . Though the pick - up rate of hypoglycemia by venous blood glucometer [28%] was slightly better compared to the capillary blood glucometer value [22%] , the overa ll pick - up rate of hypoglycemia by glucometer is very low compared to the laboratory method [56%]. CONCLUSION : The glucometer as a sole measuring device to screen neonatal hypoglycemia is not satisfactory and confirmation with the laboratory measurements o f plasma glucose is still of up most importance.

    A nationally representative survey was carried out to determine the distribution of blood glucose and cholesterol in adult population of Bangladesh in the absence of existing data. The study adopted a multistage and geographically clustered sampling technique of households. A total of 2610 individuals (1444 men and 1166 women) aged 25-64 years were selected from rural and urban areas. Capillary blood glucose and total cholesterol levels were measured using an overnight fasting state. The mean age of the participants was 41 years [standard deviation (SD), 11 years]. Half of them (49%) were from urban areas. Half of them (51%) had primary or higher education. Mean glucose was 74mg/dL (SD 23mg/dL). Men had higher mean glucose levels (79mg/dL) than women (67mg/dL). Age-standardized prevalence of diabetes (blood glucose level ≥126mg/dL and/or use of anti-diabetic medication) was 5.5%. In men, it was almost two-and-half times (7.6%) compared with women (2.8%). It was also double in urban areas (7.8%) compared with rural areas (3.4%). Mean cholesterol level among all participants was 167mg/dL (SD 26mg/dL). Men and women had almost similar levels (169mg/dL versus 166mg/dL, respectively). Prevalence of high cholesterol level (≥240mg/dL) was very low (1.3%) in both men (2.2%) and women (0.5%). However, the prevalence of borderline high cholesterol was substantial (5.8%) in this sample. The prevalence of high hypercholesterolemia is low, whereas there is a high prevalence of borderline high cholesterol and diabetes in the adult population of Bangladesh. This warrants population-based interventions to tackle this problem. Copyright © 2015 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.

    Objectives: To find the incidence of hyperglycemia (blood glucose [BG] ≥150 mg/dl), hypoglycemia (BG ≤60 mg/dl), and variability (presence of hypoglycemia and hyperglycemia) in critically ill children in the 1st week of Intensive Care Unit (ICU) stay and their association with mortality, length of ICU stay, and organ dysfunction. Materials and Methods: The design was a retrospective observational cohort study. Consecutive children ≤18 years of age admitted from March 2003 to April 2012 in a combined adult and pediatric closed ICU. Relevant data were collected from chart review and hospital database. Results: Out of 258 patients included, isolated hyperglycemia was seen in 139 (53.9%) and was unrelated to mortality and morbidity. Isolated variability in BG was noted in 76 (29.5%) patients and hypoglycemia was seen in 9 (3.5%) patients. BG variability was independently associated with multiorgan dysfunction syndrome on multivariate analysis (adjusted odds ratio [OR]: 7.1; 95% confidence interval [CI]: 1.6–31.1). Those with BG variability had longer ICU stay (11 days vs. 4 days, on log-rank test, P = 0.001). Insulin use was associated with the occurrence of variability (adjusted OR: 3.6; 95% CI: 1.8–7.0). Conclusion: Glucose disorders were frequently observed in critically ill children. BG variability was associated with multiorgan dysfunction and increased ICU stay.

    To analyse the effect of chronic caffeine use on risk reduction and prognosis of diabetes mellitus. In this 60-day study, five groups of 11 healthy male Wistar rats were selected to receive one of four doses (37.5, 56.2, 75.0 or 93.0 mg/kg per day) of caffeine orally or no caffeine (control). The effect of caffeine on glycaemia and glucose tolerance was evaluated. After 15 days, each group was treated with 60 mg/kg of streptozotocine to induce diabetes mellitus, and glycaemia and glucose tolerance were assessed for a further 45 days. In nondiabetic rats, caffeine had no effect on blood glucose. Compared with controls, the fasting blood glucose levels declined significantly in two caffeine-treated groups (93.0 mg/kg per day and 56.2 mg/kg per day) during the first 15 days following diabetes induction. Glucose tolerance was significantly improved 120 min after glucose loading in all caffeine-treated groups. The mean ± SE half-maximal effective concentration of caffeine was 35.79 ± 2.44 mg/dl. Blood glucose levels decreased, and glucose tolerance improved, in diabetic rats administered increasing doses of caffeine.

    We have expanded a former compartmental model of blood glucose regulation for healthy and type 2 diabetic subjects. The former model was a detailed physiological model which considered the interactions of three substances, glucose, insulin and glucagon on regulating the blood sugar. The main...... drawback of the former model was its restriction on the route of glucose entrance to the body which was limited to the intravenous glucose injection. To handle the oral glucose intake, we have added a model of glucose absorption in the gastrointestinal tract to the former model to address the resultant...... variations of blood glucose concentrations following an oral glucose intake. Another model representing the incretins production in the gastrointestinal tract along with their hormonal effects on boosting pancreatic insulin production is also added to the former model. We have used two sets of clinical data...

    2007-01-01

    The purpose of this review paper is to discuss the research literature on the effects of blood glucose levels on executive and non-executive functions in humans. The review begins with a brief description of blood glucose, how it has been studied, previous syntheses of prior studies, and basic results regarding the role of blood glucose on cognitive functioning. The following sections describe work that investigated the effect of blood glucose on both non-executive and executive functions (e.g., sensory processing, psychomotor functioning, attention, vigilance, memory, language and communication, judgement and decision-making, and complex task performance). Within each section, summaries of the findings and challenges to the literature are included. Measurement conversions of blood glucose levels, blood glucose values, and associated symptoms are depicted. References to the types of tests used to investigate blood glucose and cognitive performance are provided. For more detailed descriptions of references within (and in addition to) this paper, an annotated bibliography is also provided. Several moderator variables including individual differences and contextual variables related to the effects of blood glucose levels on performance (e.g., age, gender, time of day, familiarity with the task and symptom awareness, expectancy effects, dose dependent effects, time dependent effects, task specific effects, rising and falling blood glucose levels, and speed and/or accuracy trade-offs) are addressed later in the paper. Some suggestions for future experimental methodologies are also made.

    Background: Conflicting evidence exists on the role of long-term fructose consumption on health. No systematic review has addressed the effect of isoenergetic fructose replacement of other sugars and its effect on glycated hemoglobin (HbA1c), fasting blood glucose, insulin, and triglycerides.Objective: The objective of this study was to review the evidence for a reduction in fasting glycemic and insulinemic markers after chronic, isoenergetic replacement of glucose or sucrose in foods or beverages by fructose. The target populations were persons without diabetes, those with impaired glucose tolerance, and those with type 2 diabetes.Design: We searched the Cochrane Library, MEDLINE, EMBASE, the WHO International Clinical Trials Registry Platform Search Portal, and clinicaltrials.gov The date of the last search was 26 April 2016. We included randomized controlled trials of isoenergetic replacement of glucose, sucrose, or both by fructose in adults or children with or without diabetes of ≥2 wk duration that measured fasting blood glucose. The main outcomes analyzed were fasting blood glucose and insulin as well as fasting triglycerides, blood lipoproteins, HbA1c, and body weight.Results: We included 14 comparison arms from 11 trials, including 277 patients. The studies varied in length from 2 to 10 wk (mean: 28 d) and included doses of fructose between 40 and 150 g/d (mean: 68 g/d). Fructose substitution in some subgroups resulted in significantly but only slightly lowered fasting blood glucose (-0.14 mmol/L; 95% CI: -0.24, -0.036 mmol/L), HbA1c [-10 g/L (95% CI: -12.90, -7.10 g/L; impaired glucose tolerance) and -6 g/L (95% CI: -8.47, -3.53 g/L; normoglycemia)], triglycerides (-0.08 mmol/L; 95% CI: -0.14, -0.02 mmol/L), and body weight (-1.40 kg; 95% CI: -2.07, -0.74 kg). There was no effect on fasting blood insulin or blood lipids.Conclusions: The evidence suggests that the substitution of fructose for glucose or sucrose in food or beverages may be of benefit to

    The present studies examined the relationship between fasting blood glucose and Hb A(1c) in C57BL/6J, DBA/2J, and KK/HlJ mice with and without diabetes mellitus. Daily averaged blood glucose levels based on continuous glucose monitoring and effects of 6-h vs. overnight fasting on blood glucose were determined. Daily averaged blood glucose levels were highly correlated with Hb A(1c), as determined with a hand-held automated device using an immunodetection method. R(2) values were 0.90, 0.95, and 0.99 in KK/HIJ, C57BL/6J, and DBA/2J, respectively. Six-hour fasting blood glucose correlated more closely with the level of daily averaged blood glucose and with Hb A(1c) than did blood glucose following an overnight fast. To validate the immunoassay-determined Hb A(1c), we also measured total glycosylated hemoglobin using boronate HPLC. Hb A(1c) values correlated well with total glycosylated hemoglobin in all three strains but were relatively lower than total glycosylated hemoglobin in diabetic DBA/2J mice. These results show that 6-h fasting glucose provides a superior index of glycemic control and correlates more closely with Hb A(1c) than overnight-fasted blood glucose in these strains of mice.

    Although the effects on prognosis of blood glucose level variability have gained increasing attention, it is unclear whether blood glucose level variability itself or the manifestation of pathological conditions that worsen prognosis. Then, previous reports have not been published on variability models of perioperative blood glucose levels. The aim of this study is to establish a novel variability model of blood glucose concentration using an artificial pancreas. We maintained six healthy, male beagles. After anesthesia induction, a 20-G venous catheter was inserted in the right femoral vein and an artificial pancreas (STG-22, Nikkiso Co. Ltd., Tokyo, Japan) was connected for continuous blood glucose monitoring and glucose management. After achieving muscle relaxation, total pancreatectomy was performed. After 1 h of stabilization, automatic blood glucose control was initiated using the artificial pancreas. Blood glucose level varied for 8 h, alternating between the target blood glucose values of 170 and 70 mg/dL. Eight hours later, the experiment was concluded. Total pancreatectomy was performed for 62 ± 13 min. Blood glucose swings were achieved 9.8 ± 2.3 times. The average blood glucose level was 128.1 ± 5.1 mg/dL with an SD of 44.6 ± 3.9 mg/dL. The potassium levels after stabilization and at the end of the experiment were 3.5 ± 0.3 and 3.1 ± 0.5 mmol/L, respectively. In conclusion, the results of the present study demonstrated that an artificial pancreas contributed to the establishment of a novel variability model of blood glucose levels in beagles.

    Emotional arousal enhances memory, and this memory-enhancing effect may involve neurochemicals released by arousal, such as glucose and cortisol. Physiological consequences of arousal change with age, and these changes may contribute to age-related memory decline. The present study examined whether emotionally arousing pictures would affect glucose and cortisol levels and enhance memory in young and older adults. Blood glucose and salivary cortisol were measured once before and six times after young and old adults viewed either 60 highly arousing or 60 relatively neutral pictures. Recall for the stimuli was measured 75 min later. The results indicated that recall was impaired in older adults. Arousal as measured by self-report enhanced recall in both young and older adults. However, arousal did not affect glucose or cortisol levels in either group. These findings demonstrate that changes in blood glucose or salivary cortisol levels are not necessary for arousal to enhance memory.

    In this paper, the propagation characteristics of near-infrared (NIR) light in the palm tissue are analyzed,and the principle and feasibility of using transcutaneous diffuse reflectance spectroscopy for non-invasive blood glucose detection are presented. An optical probe suitable for measuring the diffuse reflectance spectrum of human palm and a non-invasive blood glucose detection system using NIR spectroscopy are designed. Based on this system, oral glucose tolerance tests are performed to measure the blood glucose concentrations of two young healthy volunteers. The partial least square calibration model is then constructed by all individual experimental data. The final result shows that correlation coefficients of the two experiments between the predicted blood glucose concentrations and the reference blood glucose concentrations are 0.9870 and 0.9854, respectively. The root mean square errors of prediction of full cross validation are 0.54 and 0.52 mmol/1, respectively.

    This study was aimed to investigate the relationship between breakfast and serum glucose, insulin and glucagon concentrations in order to establish a model breakfast appropriate for Chinese. Twenty-four volunteers were randomly assigned to four study groups: high carbohydrate breakfast, high fat and protein breakfast, the typical breakfast and fasting. Each subject had serum and urine samples collected while fasting and at 1,2 and 3.5 hours following the meal. The concentration of serum glucose, insulin and glucagon was measured. The levels of serum glucose in group A,B and C differed significantly at 1 and 2 hour after meal compared to those at fasting (P<0.05). The serum glucose in group A increased insignificantly after meal. The serum insulin levels were in group A,B and C significant different compared with control group(P<0.05).Those peaked at 1 hour after meal ,with group C rising the furthest. Compared with the fasting group, the serum glucagons rose and maintained the increase after breakfast in group A,B and C (P<0.05).The data suggested that various diets with different calorigenic amounts increased hormone concentration to various extents. We found that a breakfast rich in carbohydrates could maintain proper blood glucose level.

    Monocytes are innate immune cells that can be activated by pathogens and inflammation associated with certain chronic inflammatory diseases. Activation of monocytes induces effector functions and a concomitant shift from oxidative to glycolytic metabolism that is accompanied by increased glucose transporter expression. This increased glycolytic metabolism is also observed for trained immunity of monocytes, a form of innate immunological memory. Although in vitro protocols examining glucose transporter expression and glucose uptake by monocytes have been described, none have been examined by multi-parametric flow cytometry in whole blood. We describe a multi-parametric flow cytometric protocol for the measurement of fluorescent glucose analog 2-NBDG uptake in whole blood by total monocytes and the classical (CD14(++)CD16(-)), intermediate (CD14(++)CD16(+)) and non-classical (CD14(+)CD16(++)) monocyte subpopulations. This method can be used to examine glucose transporter expression and glucose uptake for total monocytes and monocyte subpopulations during homeostasis and inflammatory disease, and can be easily modified to examine glucose uptake for other leukocytes and leukocyte subpopulations within blood.

    Blood glucose management is one of the important therapies in the intensive care unit (ICU). However, blood glucose management using the sliding-scale method increases the workload of ICU nurses. An artificial pancreas, STG-22, has been developed to continuously monitor blood glucose levels and to maintain them at appropriate levels. In this study, we examined the hypothesis that compared to conventional methods, blood glucose management using the STG-22 reduces the workload of ICU nurses and has a positive impact on awareness regarding the management of blood glucose. This study included 45 patients who underwent elective surgery and were treated at the ICU postoperatively. The patients were separated into the following two groups: (1) blood glucose was maintained using the STG-22 (AP group) and (2) blood glucose was maintained using the sliding-scale method (SS group). In addition, a questionnaire was developed for an awareness survey of ICU nurses (N = 20). The frequency of blood sampling and number of double checks were significantly lower in the AP group (1.3 ± 1.4 vs. 8.9 ± 8.1 times/admission, P blood glucose.

    Post-transplant-diabetes-mellitus (PTDM) is a frequent complication after kidney transplantation. One-hundred-and-seven patients with kidney transplantation were screened for the occurrence of PTDM. Of these, full data sets from 49 subjects were available with documented glucose concentrations during maintenance hemodialysis (MHD) and regular clinical follow-up of 7-34 months. For assessment of glucose metabolism the response to a standard meal during MHD was used in normoglycemic patients based on fasting blood glucose. Abnormal postprandial blood glucose concentration was defined as >140 mg/dl 2 h after food intake.Twelve end stage renal disease patients had abnormal postprandial blood glucose on MHD. All 12 subjects but also four MHD patients with normal postprandial and fasting blood glucose values developed PTDM. Multivariate Cox-regression analysis revealed that abnormal postprandial blood glucose is a strong predictor for PTDM (Hazard ratio: 42.3 (IQR: 7.9-227.2); p<0.001). Fasting blood glucose (94 vs. 100 mg/dl) was not different between MHD patients who did (n=16) or did not (n=33) develop PTDM.This study suggests that measurement of postprandial blood glucose during MHD identifies patients who develop PTDM after kidney transplantation. It should be used for screening of patients at risk.

    This study was conducted to determine the impact of dietary acculturation on the health status of newly arrived international students at Virginia Tech in Fall 2010. Thirty-five international students, 18-36 years of age, completed the study. Data were collected at 3 different time periods (V1, V2, and V3) approximately 6 weeks apart. A food frequency- and dietary pattern-related questionnaire was administered and numerically coded responses were analyzed. Twenty-four-hour dietary recall data were also collected at V1, V2, and V3. Body weight, fasting blood glucose level, and blood pressure of study participants were also determined at each time period. Total sample population (TSP) had a significant increase in mean weight of 2.79 lb from visit 1 (V1) to visit 3 (V3) (p = .0082). Ten participants gained an average of 9.0 lb (participants who gained weight; n = 10). There was also an increase in the frequency of consumption of high-calorie American food items from V1 to V3. However, there were no significant changes in mean systolic blood pressure and mean fasting blood glucose was significantly lower at V3 than at V1. There was a gradual shift in the dietary patterns of international students towards the American diet. Dietary acculturation led to weight gain among some of the students, which may potentially have a negative impact on their health status if continued for longer time periods.

    Chrysobalanus icaco L. is a medicinal plant present in the Brazilian coastline and known for its hypoglicemic and antioxidant properties. Here, we assessed the beneficial metabolic effects of the aqueous extract of C. icaco (AECI) leaves in diet-induced obese mice. Swiss mice were fed standard chow (SC used as controls) or high-fat diet (HFD) to induce obesity. After 10 weeks, mice on each diet were divided into two groups with one group used as control while the other group treated with AECI for 4 weeks resulting in four groups of mice: SC; SC treated with AECI (SC + AECI); HFD; and HFD treated with AECI (HFD + AECI). AECI was administered drinking water at about 200 mg/kg. AECI was able to normalize insulin (13,682 ± 1090 vs. 9828 ± 485 AU, P fat storage in liver (72.60 ± 3.83%, P fat intake. These findings reinforce the use of AECI in hyperglycemia and highlight the potential extract's effect in preventing weight gain and fat accumulation in liver of diet-induced obese mice.

    The academic and public interest in blood glucose and its relationship to decision making has been increasing over the last decade. To investigate and evaluate competing theories about this relationship, we conducted a psychometric meta-analysis on the effect of blood glucose on decision making. We...... identified 42 studies relating to 4 dimensions of decision making: willingness to pay, willingness to work, time discounting, and decision style. We did not find a uniform influence of blood glucose on decision making. Instead, we found that low levels of blood glucose increase the willingness to pay...... and willingness to work when a situation is food related, but decrease willingness to pay and work in all other situations. Low levels of blood glucose increase the future discount rate for food; that is, decision makers become more impatient, and to a lesser extent increase the future discount rate for money...

    The natural history of impaired glucose tolerance (IGT) and Type 2 diabetes among obese children is not clear. Although the cut-off for impaired fasting glucose (IFG) has recently been changed from 110 (6.1 mmol/l) to 100 mg/dl (5.6 mmol/l), it does not seem a reliable way to find all subjects with impaired glucose homeostasis. The aim of our study was to determine whether high-normal fasting glucose level could predict the occurrence of IGT and metabolic syndrome. Three hundred and twenty-three Italian obese children and adolescents were included in the study (176 females, mean age 11+/-2.9 yr; mean body mass index z-score: 3+/-0.6). Waist circumference, serum glucose, insulin, triglyceride, cholesterol HDL, blood pressure were evaluated and an oral glucose tolerance test (OGTT) was performed. The prevalence of IFG and IGT were respectively 1.5% (5 subjects) and 5% (18 patients); no diabetic patients were found. Metabolic syndrome was diagnosed in 20% of patients. Fasting glycemia values youths. Interestingly high-normal fasting plasma glucose levels constitute an independent risk factor for IGT among obese children and adolescents; therefore, this very easy-to-use parameter may help to identify obese patients at increased risk of diabetes or at least could suggest in which subjects to perform an OGTT.

    Full Text Available Estimation of glomerular filtration rate (eGFR is one of the current clinical methods for identifying risk for diabetic nephropathy in subjects with type 1 diabetes (T1D. Hyperglycemia is known to influence GFR in T1D and variability in blood glucose at the time of eGFR measurement could introduce bias in eGFR. We hypothesized that simultaneously measured blood glucose would influence eGFR in adults with T1D.Longitudinal multivariable mixed-models were employed to investigate the relationships between blood glucose and eGFR by CKD-EPI eGFRCYSTATIN C over 6-years in the Coronary Artery Calcification in Type 1 diabetes (CACTI study. All subjects with T1D and complete data including blood glucose and cystatin C for at least one of the three visits (n = 616, 554, and 521, respectively were included in the longitudinal analyses.In mixed-models adjusting for sex, HbA1c, ACEi/ARB, protein and sodium intake positive associations were observed between simultaneous blood glucose and eGFRCYSTATIN C (β±SE:0.14±0.04 per 10 mg/dL of blood glucose, p<0.0001, and hyperfiltration as a dichotomous outcome (OR: 1.04, 95% CI: 1.01-1.07 per 10 mg/dL of blood glucose, p = 0.02.In our longitudinal data in subjects with T1D, simultaneous blood glucose has an independent positive effect on eGFRCYSTATIN C. The associations between blood glucose and eGFRCYSTATIN C may bias the accurate detection of early diabetic nephropathy, especially in people with longitudinal variability in blood glucose.

    A widely used method in monitoring glycemic status of ICU patients is point-of-care (POC) monitoring devices. A possible limitation to this method is altered peripheral blood flow in patients in shock, which may result in over/underestimations of their true glycemic status. This study aims to determine the accuracy of blood glucose measurements with a POC meter compared to laboratory methods in critically ill patients in shock. POC blood glucose was measured with a glucose-1-dehydrogenase-based reflectometric meter. The reference method was venous plasma glucose measured by a clinical chemistry analyzer (glucose oxidase-based). Outcomes assessed were concordance to ISO 15197:2003 minimum accuracy criteria for glucose meters, bias in glucose measurements obtained by the 2 methods using Bland-Altman analysis, and clinical accuracy through modified error grid analysis. A total of 186 paired glucose measurements were obtained. ISO 2003 accuracy criteria were met in 95.7% and 79.8% of POC glucose values in the normotensive and hypotensive group, respectively. Mean bias for the normotensive group was -12.4 mg/dL, while mean bias in the hypotensive group was -34.9 mg/dL. POC glucose measurements within the target zone for clinical accuracy were 90.2% and 79.8% for the normotensive and hypotensive group, respectively. POC blood glucose measurements were significantly less accurate in the hypotensive subgroup of ICU patients compared to the normotensive group. We recommend a lower threshold in confirming POC blood glucose with a central laboratory method if clinically incompatible. In light of recently updated accuracy standards, we also recommend alternative methods of glucose monitoring for the ICU population as a whole regardless of blood pressure status.

    Full Text Available Based on the evidence that hyperglycaemia aggravates ischaemic cerebral injury, it has been suggested that blood glucose levels be kept within 200 mg/dL during intracranial neurosurgery. Hypoglycaemia, however, can be a serious problem if glucose-containing solutions are avoided during the first four hours, as suggested in some studies. In order to explore the possibility of administering glucose in moderation so that the blood glucose levels are within acceptable limits, but at the same time the risk of hyoglycaemia is eliminated, we compared two intraoperative fluid regimens. Of the 52 neurosurgical patients studied, 32 patients received alternately 500 ml of 5% dextrose in normal saline and Ringer′s lactate (DNS/RL Group and 18 patients received alternately 500 ml of Ringer′s lactate and normal saline (RL/NS Group. Blood glucose concentrations were determined at the end of each unit of fluid, until the patient received 4 units of fluid. In the DNS/RL group, blood glucose values peaked with the administration of each unit of DNS and tended to return towards the baseline with the subsequent RL, but remained higher than the previous control value. In the RL/NS group, there was a progressive increase in blood glucose values throughout the study period, but the increase was not statistically significant. The blood glucose levels were significantly different between the two groups after each unit of fluid except at the end of the fourth unit. Two patients in the RL/NS group had hypoglycaemia. In conclusion, the DNS/RL regimen maintains blood glucose levels within acceptable limits while avoiding the risk of hyperglycaemia. Withholding glucose completely, lowers blood glucose levels, but carries a risk of hypoglycaemia in some patients.

    Full Text Available Introduction: Type 2 diabetes mellitus is deficiency of insulin and caused by decreases of insulin receptor or bad quality of insulin. As a result, insulin hormone does not work effectively in blood glucose regulation. String bean juice contains thiamin and fiber may regulate blood glucose level. The aim of this study was to analyze the effect of string bean juice to decrease blood glucose level of patients with type 2 diabetes mellitus. Method: This study employed a quasy-experimental pre-post test control group design and purposive sampling.  The population were all type 2 diabetes mellitus patients in Puskesmas Pacar Keling Surabaya. Sample were 12 patients who met inclusion criteria. The independent variable was string bean juice and dependent variable was blood glucose level. Data were analyzed by using Paired T-test with significance level of α≤ 0.05 and Independent T-test with significant level of α≤0.05. Result: The results showed that string bean juice has an effect on decreasing blood glucose between pre test and post test for blood glucose with independent T-test is p=0.003. Analysis: In conclusion, string bean juice has an effect on blood glucose level in patients with type 2 diabetes mellitus. Discussion: The possible explanation for this findings is string bean juice contains two ingredients: thiamine and fiber. Thiamine helps support insulin receptors and glucose transporter in cells hence GLUT-4 could translocated to the cell membrane brought glucouse enter to the  intracellular compartment, that leads to blood glucouse level well regulated.  Dietary fiber reduces food transit time so slowing the glucose absorption. Therefore blood glucose level will be decreased.

    Blood glucose concentration measurement is essential for the diagnosis and treatment of diabetes. However, conventional glucose measurement methods are invasive and not suitable for real-time monitoring. This study demonstrated a noninvasive blood glucose measurement method using optical coherence tomography to image human lip in vivo. Optical coherence tomography (OCT) is a noninvasive and depth-resolved technique capable of acquiring tissue structure images in real time. Human lip has very thin skin and is full of blood vessels, which is appropriate for noninvasive glucose measurement. To verify the feasibility of OCT for glucose concentration monitoring, two groups of OCT imaging data were obtained from human lips of normal people. In one group, OCT images of lip were acquired from people on an empty stomach. In the other group, the same sites of lip were observed by OCT 2 hours after breakfast. Evident differences were found from two groups of OCT images that correspond to preprandial glucose and 2- hour postprandial glucose, respectively. The relationship between OCT image and blood glucose concentration was investigated. The result indicates that OCT possesses considerable prospects in terms of noninvasive blood glucose measurement.

    This study tested the hypothesis that inducing hyperinsulinemia and hyperglycemia in dogs, by infusing glucose chronically intravenously, would increase tubular sodium reabsorption and cause hypertension. Glucose was infused for 6 days (14 mg.kg(-1).min(-1) iv) in five uninephrectomized (UNX) dogs. Mean arterial pressure (MAP) and renal blood flow (RBF) were measured 18 h/day using DSI pressure units and Transonic flow probes, respectively. Urinary sodium excretion (UNaV) decreased significantly on day 1 and remained decreased over the 6 days, coupled with a significant, sustained increase in RBF, averaging approximately 20% above control on day 6. Glomerular filtration rate and plasma renin activity (PRA) also increased. However, although MAP tended to increase, this was not statistically significant. Therefore, the glucose infusion was repeated in six dogs with 70% surgical reduction in kidney mass (RKM) and high salt intake. Blood glucose and plasma insulin increased similar to the UNX dogs, and there was significant sodium retention, but MAP still did not increase. Interestingly, the increases in PRA and RBF were prevented in the RKM dogs. The decrease in UNaV, increased RBF, and slightly elevated MAP show that glucose infusion in dogs caused a sustained increase in tubular sodium reabsorption by a mechanism independent of pressure natriuresis. The accompanying increase in PRA, together with the failure of either RBF or PRA to increase in the RKM dogs, suggests the site of tubular reabsorption was before the macula densa. However, the volume retention and peripheral edema suggest that systemic vasodilation offsets any potential renal actions to increase MAP in this experimental model in dogs.

    Approximately 14 million people in the USA and more than 140 million people worldwide suffer from Diabetes Mellitus. The current glucose sensing technique involves a finger puncture several times a day to obtain a droplet of blood for chemical analysis. Recently we proposed to use optical coherence tomography (OCT) for continuous noninvasive blood glucose sensing through skin. In this paper we tested the OCT technique for noninvasive monitoring of blood glucose concentration in lip tissue of New Zealand rabbits and Yucatan micropigs during glucose clamping experiments. Obtained results show good agreement with results obtained in skin studies, good correlation of changes in the OCT signal slope measured at the depth of 250 to 500 μm with changes in blood glucose concentration, and higher stability of the OCT data points than that obtained from skin.

    Full Text Available Background and Aims: Blood donation from glucose-6-phosphate dehydrogenase (G6PD-deficient and sickle cell trait (SCT donors might alter the quality of the donated blood during processing, storage or in the recipient′s circulatory system. The aim of this study was to determine the prevalence of G6PD deficiency and SCT among blood donors coming to King Khalid University Hospital (KKUH in Riyadh. It was also reviewed the benefits and risks of transfusing blood from these blood donors. Materials and Methods: This cross-sectional study was conducted on 1150 blood samples obtained from blood donors that presented to KKUH blood bank during the period April 2006 to May 2006. All samples were tested for Hb-S by solubility test, alkaline gel electrophoresis; and for G6PD deficiency, by fluorescent spot test. Results: Out of the 1150 donors, 23 (2% were diagnosed for SCT, 9 (0.78% for G6PD deficiency and 4 (0.35% for both conditions. Our prevalence of SCT and G6PD deficiency is higher than that of the general population of Riyadh. Conclusion: We recommend to screen all units for G6PD deficiency and sickle cell trait and to defer donations from donors with either of these conditions, unless if needed for special blood group compatibility, platelet apheresis or if these are likely to affect the blood bank inventory. If such blood is to be used, special precautions need to be undertaken to avoid complications in high-risk recipients.

    False elevation of blood glucose levels measured by glucose dehydrogenase pyrroloquinoline quinone (GDH-PQQ)-based glucose self-monitoring systems; glucometer) in peritoneal dialysis (PD) patients using icodextrin solution has been well documented. However, adverse hypoglycemic events caused by misreadings for blood glucose are still being reported. We aimed to study blood glucose levels measured simultaneously using different methods in PD patients with switching of icodextrin, and throughout daily exchanges either using icodextrin or not. We recruited 100 PD patients, including 40 using icodextrin; 128 hemodialysis patients served as a reference. Fasting serum glucose was measured using our laboratory reference method (LAB) and 2 glucose self-monitoring systems based on glucose dehydrogenase nicotinamide adenine dinucleotide (GDH-NAD) and GDH-PQQ respectively. 80 PD patients had a second follow-up study. A time course study was performed in 16 PD patients through measuring fingertip glucose using the 2 glucose self-monitoring systems during daily exchanges. The differences in measured serum glucose levels in (PQQ minus LAB) versus (NAD minus LAB) were markedly increased in PD patients using icodextrin compared to other patient groups, and was further confirmed by the follow-up study in patients that switched to icodextrin. The high serum glucose levels measured by the GDH-PQQ-based glucose self-monitoring system were present throughout all exchanges during the day in patients using icodextrin solution. False elevation of blood glucose measured by GDH-PQQ-based glucose self-monitoring systems exists in patients using icodextrin. To avoid misinterpretation of hyperglycemia and subsequent over-injection of insulin, GDH-PQQ-based glucose self-monitoring systems should not be used in PD patients.

  7. A meta-analysis of blood glucose effects on human decision making.

    2016-05-01

    The academic and public interest in blood glucose and its relationship to decision making has been increasing over the last decade. To investigate and evaluate competing theories about this relationship, we conducted a psychometric meta-analysis on the effect of blood glucose on decision making. We identified 42 studies relating to 4 dimensions of decision making: willingness to pay, willingness to work, time discounting, and decision style. We did not find a uniform influence of blood glucose on decision making. Instead, we found that low levels of blood glucose increase the willingness to pay and willingness to work when a situation is food related, but decrease willingness to pay and work in all other situations. Low levels of blood glucose increase the future discount rate for food; that is, decision makers become more impatient, and to a lesser extent increase the future discount rate for money. Low levels of blood glucose also increase the tendency to make more intuitive rather than deliberate decisions. However, this effect was only observed in situations unrelated to food. We conclude that blood glucose has domain-specific effects, influencing decision making differently depending on the relevance of the situation to acquiring food. (PsycINFO Database Record

    Introduction: Little is known about blood flow in sarcomas. Our purpose was to study glucose metabolism and blood flow in untreated localized musculoskeletal tumors of the extremities using [{sup 18}F]fluorodeoxyglucose (FDG), oxygen-15 labeled water ([15O]H{sub 2}O) and positron emission tomography (PET). Methods: Six patients with high-grade osteosarcoma (OS), two with soft-tissue sarcoma (STS) and one with aneurysmal bone cyst had PET studies with [15O]H{sub 2}O and FDG. Arterial blood sampling and autoradiography calculation method were used to define blood flow as milliliters per 100 g times minutes. Tumor FDG uptake was measured as standardized uptake values (SUVs) and regional metabolic rates for FDG (rMRFDG). Two patients also had FDG PET studies during (one patient) and after (two patients) preoperative chemotherapy. All patients underwent dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). The PET findings were compared with the clinical follow-up data and results of DCE-MRI. Results: Blood flow in bone tumors was 31.7-75.2 ml/(100 gxmin) and in STS 9.0-45.9 ml/(100 gxmin). [{sup 18}F]-Fluorodeoxyglucose uptake and rMRFDG in untreated bone tumors were 5.4-18.4 and 10.9-57.4 {mu}mol/100 g/min, respectively. [{sup 18}F]-Fluorodeoxyglucose uptake and rMRFDG in STS were 2.6-11.5 and 5.6-32.2 {mu}mol/100 g/min, respectively. Four of five sarcomas with SUV>9.0 have already relapsed. High blood flow in untreated OS was related to long overall survival, while the predictive power of glucose metabolism was less apparent. Good histopathological response to therapy was not associated with long survival. Conclusions: Measurement of blood flow in musculoskeletal tumors appears to be feasible by PET and [{sup 15}O]H{sub 2}O. The influence of tumor blood flow and glucose metabolism on the final outcome in sarcoma is variable and needs further research.

    2016-12-01

    This paper presents Fuzzy-PID (FPID) control scheme for a blood glucose control of type 1 diabetic subjects. A new metaheuristic Cuckoo Search Algorithm (CSA) is utilized to optimize the gains of FPID controller. CSA provides fast convergence and is capable of handling global optimization of continuous nonlinear systems. The proposed controller is an amalgamation of fuzzy logic and optimization which may provide an efficient solution for complex problems like blood glucose control. The task is to maintain normal glucose levels in the shortest possible time with minimum insulin dose. The glucose control is achieved by tuning the PID (Proportional Integral Derivative) and FPID controller with the help of Genetic Algorithm and CSA for comparative analysis. The designed controllers are tested on Bergman minimal model to control the blood glucose level in the facets of parameter uncertainties, meal disturbances and sensor noise. The results reveal that the performance of CSA-FPID controller is superior as compared to other designed controllers.

    Artificial pancreas technology, involving "closed-loop" controls with real-time blood glucose monitoring, has been increasing in reliability as its potential for clinical use and application grows. One such device, based on this technology, is the STG-22 (Nikkiso Co., Ltd., Tokyo, Japan) artificial pancreas apparatus. In order to assess the reliability and accuracy of the device for measuring blood glucose, it is important to compare its readings to those obtained using a 'gold standard' method, such as the hexokinase method. Therefore, in the present study, canine blood [glucose] measurements using the STG-22 were compared to those obtained using a previously established commercial reagent, Quickauto-Neo GLU-HK. Furthermore, two different sample types (whole blood versus plasma constituent) were compared to determine which sample type results in more accurate and optimal readings with the STG-22. Given that the STG-22 was not primarily designed for canine blood samples, results for canine blood samples were not accurate. Measurements performed by the STG-22 with whole blood were significantly lower than reference [glucose] counterparts. Alternatively, an opposite trend was observed with plasma measurements that were significantly higher. A conversion format using the following formula, Hexokinase [glucose] = STG-22 [glucose] × 1.407 + 1.532, was observed with canine samples in our study.

    This paper examines the use of photoacoustic spectroscopy (PAS) at an excitation wavelength of 905 nm for making continuous non-invasive blood glucose measurements. The theoretical background of the measurement technique is verified through simulation. An apparatus is fabricated for performing photoacoustic measurements in vitro on glucose solutions and in vivo on human subjects. The amplitude of the photoacoustic signals measured from glucose solutions is observed to increase with the solution concentration, while photoacoustic amplitude obtained from in vivo measurements follows the blood glucose concentration of the subjects, indicating a direct proportionality between the two quantities. A linear calibration method is applied separately on measurements obtained from each individual in order to estimate the blood glucose concentration. The estimated glucose values are compared to reference glucose concentrations measured using a standard glucose meter. A plot of 196 measurement pairs taken over 30 normal subjects on a Clarke error grid gives a point distribution of 82.65% and 17.35% over zones A and B of the grid with a mean absolute relative deviation (MARD) of 11.78% and a mean absolute difference (MAD) of 15.27 mg/dl (0.85 mmol/l). The results obtained are better than or comparable to those obtained using photoacoustic spectroscopy based methods or other non-invasive measurement techniques available. The accuracy levels obtained are also comparable to commercially available continuous glucose monitoring systems.

  4. Comparative study of different control techniques for the regulation of blood glucose level in diabetic patients.

    Blood glucose regulation is of a great concern for insulin-dependant patients with excessive glucose in blood (hyperglycaemia), or low glucose profile (hypoglycaemia) due to excess insulin delivery. Both conditions can cause dangerous complications for diabetic patients, and hence glucose regulation in blood is of prime importance. Insulin pumps are used to deliver insulin in small quantities, allowing the glucose level to remain as close as possible to that of non-diabetics (near 100 mg dl(-1)). Different control techniques are used to maintain the glucose level and most of them depend on an exact mathematical or empirical model of insulin-glucose interaction. Recently, we have proposed different controllers that are based on fuzzy logic and so do not use mathematical modelling, which in general is nonlinear, complex and suffers from uncertainties. PI fuzzy controllers are physically related to classical PI and PID controllers, which are extremely popular. The parameter settings of classical and fuzzy logic controllers are based on deep common physical background. In this manuscript, a comparative study is proposed to evaluate the use of fuzzy logic controllers over other conventional controllers such as PI and PID controllers to maintain the blood glucose level within a normoglycaemic average especially when a diabetic patient is subjected to different conditions.

  5. The Effect of Insulin on the Distribution of Glucose between the Blood Plasma and the Liver

    In normal fasted rats whole liver tissue contains as much glucose as the blood plasma, i.e., the ratio of the concentrations is about unity. The concentration of glucose in hepatic intracellular water is about 1.2 times higher than in plasma water. In rats injected with insulin the concentration of glucose in the liver falls to a lesser extent than in the plasma: resulting in a ratio of concentrations higher than unity. If insulin hypoglycemia is prevented by the ingestion of glucose the concentration ratio is less than in hypoglycemic rats but still significantly above unity. In normal rats the specific activities of plasma and hepatic glucose do not differ significantly at 7.5, 15, and 30 minutes after the intravenous injection of C14-labeled glucose. In rats injected with insulin the specific activity of glucose is higher in the plasma than in the liver at 7.5 and 15 minutes, but not at 30 minutes following the injection of tracer. In insulin-treated hypoglycemic rats considerably higher concentrations of labeled glucose are found in hepatic intracellular than in plasma water. The penetration of C14-glucose from plasma into hepatic intracellular water is found to be fast. Excess insulin causes an accumulation of glucose within the liver cells by retaining newly formed glucose and by the taking up of glucose from the plasma against an existing concentration gradient.

    In FDG-PET for abdominal malignancy, the liver may be assumed as an internal standard for grading abnormal FDG uptake both in early images and in delayed images. However, physiological variables of FDG uptake by the liver, especially the effects of blood glucose level, have not yet been elucidated. Methods: FDG-PET studies of 70 patients examined at 50 to 70 min after injection (60{+-}10 min: early images) and of 68 patients examined at 80 to 100 min after injection (90{+-}10 min: delayed images) were analyzed for liver FDG uptake. Patients having lesions in the liver, spleen and pancreas; patients having bulk tumor in other areas; and patients early after chemotherapy or radiotherapy were excluded; also, patients with blood glucose level over 125 mg/dl were excluded. Results: Mean standardized uptake value (SUV) of the liver, blood glucose level and sex showed no significant differences between early images and delayed images. However, liver SUV in the delayed image showed a larger variation than that in the early image and showed significant correlation to blood glucose level. The partial correlation coefficient between liver SUV and blood glucose level in the delayed image with adjustment for sex and age was 0.73 (P<.0001). Multivariate regression coefficient (95% confidence interval) of blood glucose was 0.017 (0.013-0.021). Conclusion: Blood glucose level is an important factor affecting the normal liver FDG uptake in nondiabetic patients. In the case of higher glucose level, liver FDG uptake is elevated especially in the delayed image. This may be due to the fact that the liver is the key organ responsible for glucose metabolism through gluconeogenesis and glycogen storage.

    As diabetes causes millions of deaths worldwide every year, new methods for blood glucose monitoring are in demand. Noninvasive approaches may increase patient adherence to treatment while reducing costs, and optical coherence tomography (OCT) may be a feasible alternative to current invasive diagnostics. This study presents two methods for blood sugar monitoring with OCT in vitro. The first, based on spatial statistics, exploits changes in the light total attenuation coefficient caused by different concentrations of glucose in the sample using a 930-nm commercial OCT system. The second, based on temporal analysis, calculates differences in the decorrelation time of the speckle pattern in the OCT signal due to blood viscosity variations with the addition of glucose with data acquired by a custom built Swept Source 1325-nm OCT system. Samples consisted of heparinized mouse blood, phosphate buffer saline, and glucose. Additionally, further samples were prepared by diluting mouse blood with isotonic saline solution to verify the effect of higher multiple scattering components on the ability of the methods to differentiate glucose levels. Our results suggest a direct relationship between glucose concentration and both decorrelation rate and attenuation coefficient, with our systems being able to detect changes of 65 mg/dL in glucose concentration.

    Full Text Available INTRODUCTION: The normal blood glucose in rats is 100 mg glucose / 100 ml of blood plasma. After a 24hhour fast, a decrease around 30% of this value occurs. This reduction can reach 45% in a prolonged fast. Several processes controlled by neurohormonal mechanisms prevent a more pronounced decrease in blood glucose of animals subjected to fast. These processes are hepatic glycogenolysis, hepatic gluconeogenesis, decrease of glucose utilization and increase of fatty acids use by muscle tissue, and ketone bodies utilization by the central nervous system. OBJECTIVES: This study presents a learning object, mediated by computer, which simulates the determination of blood glucose (glycemia obtained from fed rats and from 24-hour fasted rats. MATERIALS AND METHODS: At first, cartoons were planned in order to show the biochemical and methodology fundamentals. The most representative images were selected, edited and inserted into an animation developed with the aid of the Adobe ® Flash 8 software. DISCUSSION AND RESULTS: The animated simulation of a standard glucose curve, followed by virtual evaluation of glucose in blood plasma samples were developed, associated with some questions. This object has been used by students of Biochemistry I (Pharmacy-UFRGS since second semester of 2009. The navigation features, design and interactivity have been evaluated as excellent by about 80% of them. CONCLUSION: Therefore, this learning object can be considered an adequate teaching resource as well as an innovative support in the construction of theoretical and practical knowledge of Biochemistry.

    Epidemiological studies suggest an association between breakfast skipping and body weight gain, insulin resistance or type 2 diabetes. Time when meal is consumed affects postprandial increase in energy expenditure and blood glucose, and breakfast skipping may reduce 24 h energy expenditure and elevate blood glucose level. The present study evaluated the effect of breakfast skipping on diurnal variation of energy metabolism and blood glucose. The skipped breakfast was compensated by following big meals at lunch and supper. In a randomized repeated-measure design with or without breakfast, eight males stayed twice in a room-size respiratory chamber. Blood glucose was recorded with a continuous glucose monitoring system. Breakfast skipping did not affect 24 h energy expenditure, fat oxidation and thermic effect of food, but increased overall 24 h average of blood glucose (83 ± 3 vs 89 ± 2 mg/dl, P breakfast skipping. These observations suggest that changes in glucose homeostasis precede that of energy balance, in the potential sequence caused by breakfast skipping, if this dietary habit has any effect on energy balance.:

    Full Text Available Abstract Background Previous interventions to increase physical activity and reduce cardiovascular risk factors have been targeted at individuals with established disease; less attention has been given to intervention among individuals with high risk for disease nor has there been determination of the influence of setting in which the intervention is provided. In particular, family practice represents an ideal setting for the provision and long-term maintenance of lifestyle interventions for patients at risk (ie high-normal blood pressure or impaired glucose tolerance. Methods/design The Staged Nutrition and Activity Counseling (SNAC study is a randomized clustered design clinical trial that will investigate the effectiveness and efficacy of a multi-component lifestyle intervention on cardiovascular disease risk factors and vascular function in patients at risk in primary care. Patients will be randomized by practice to either a standard of care lifestyle intervention or a behaviourally-based, matched prescriptive physical activity and diet change program. The primary goal is to increase physical activity and improve dietary intake according to Canada's Guides to Physical Activity Healthy Eating over 24 months. The primary intention to treat analysis will compare behavioral, physiological and metabolic outcomes at 6, 12 and 24 months post-randomization including estimation of incident hypertension and/or diabetes. Discussion The design features of our trial, and the practical problems (and solutions associated with implementing these design features, particularly those that result in potential delay between recruitment, baseline data collection, randomization, intervention, and assessment will be discussed. Results of the SNAC trial will provide scientific rationale for the implementation of this lifestyle intervention in primary care. Trial registration ISRCTN: ISRCTN:42921300

    2010-01-01

    Full Text Available Background: Diabetes mellitus is a common finding in the medical history of patients receiving treatment for periodontal disease. The incidence of diabetes is on the rise worldwide. Virtually, every dentist and especially the periodontist are likely to encounter an increasing number of undiagnosed diabetic patients. The conventional laboratory methods employed to detect blood glucose are time consuming and require elaborative equipment. The advent of blood glucose monitors allows the clinician to assess blood glucose at the chair side. Materials and Methods: The use of gingival capillary blood as a marker for blood glucose estimation using glucometer against the conventional laboratory method has been assessed in 60 diabetics and 70 controls. Results: The correlation between gingival and finger-stick blood was r = 0.996, P<0.001 in diabetics and controls. Correlation between gingival and laboratory method was r = 0.994, P<0.001 in cases and controls. Conclusion: The results suggest that capillary blood from the outer surface of gingiva provide an acceptable source for measuring blood glucose.

    Full Text Available Background: Cardiopulmonary bypass (CPB during coronary artery bypass grafting is thought to contribute significantly to increased blood glucose level and altered blood electrolytes balance during the operation. In this (CABG study, blood electrolytes and glucose during CPB in insulin-dependent diabetic and non-diabetic patients were assessed with special emphasis on the trend of the changes. Materials and Methods: Blood glucose and electrolytes were assessed in 30 insulin-dependent diabetic and 30 non-diabetic patients, classified as class II and III American Society of Anesthesiologist, before, during, and after CPB. Repeated-measures analysis of variance (ANOVA was used to compare the trend of the changes during CPB for the two groups. Results: The trend in blood glucose level did not show any significant difference between two groups ( P = 0.59. For other blood factors, no significant between-group difference was detected except for PaCO 2 ( P = 0.002. Conclusion: The study suggested that the changes in blood electrolytes and the increase in blood glucose level do not differ between insulin dependent diabetic and non-diabetic patients.

    Full Text Available We present a method for the determination of blood glucose using dried filter paper blood spots.To validate this method, we compared our results using filter paper and simultaneously collected venous blood. We demonstrated that there is a linear relationship between the filter paper glucose levels and those determined in whole blood (r=0.98. There was no significant difference between the results of the two methods (p>0.05.This method is a cheap alternative which may improve the control of diabetes mellitus, and may also be very useful in the diagnosis of postprandial hypoglycemia and other special situations.

    Research highlights: {yields} A new mutant of PQQ-GDH designed for glucose biosensors application. {yields} First mutant of PQQ-GDH with higher activity for D-glucose than the Wild type. {yields} Position N428 is a key point to increase the enzyme activity. {yields} Molecular modeling shows that the N428 C mutant displays a better interaction for PQQ than the WT. -- Abstract: We report for the first time a soluble PQQ-glucose dehydrogenase that is twice more active than the wild type for glucose oxidation and was obtained by combining site directed mutagenesis, modelling and steady-state kinetics. The observed enhancement is attributed to a better interaction between the cofactor and the enzyme leading to a better electron transfer. Electrochemical experiments also demonstrate the superiority of the new mutant for glucose oxidation and make it a promising enzyme for the development of high-performance glucose biosensors and biofuel cells.

    Depression is more common among diabetes people than in the general population. In the present study, blood glucose change in depression animal model was characterized by various types of hyperglycemia models such as d-glucose-fed-, immobilization stress-, and drug-induced hyperglycemia models. First, the ICR mice were enforced into chronic restraint stress for 2h daily for 2 weeks to produce depression animal model. The animals were fed with d-glucose (2g/kg), forced into restraint stress for 30min, or administered with clonidine (5μg/5μl) supraspinally or spinally to produce hyperglycemia. The blood glucose level in depression group was down-regulated compared to that observed in the normal group in d-glucose-fed-, restraint stress-, and clonidine-induced hyperglycemia models. The up-regulated corticosterone level induced by d-glucose feeding or restraint stress was reduced in the depression group while the up-regulation of plasma corticosterone level is further elevated after i.t. or i.c.v. clonidine administration in the depression group. The up-regulated insulin level induced by d-glucose feeding or restraint stress was reduced in the depression group. On the other hand, blood corticosterone level in depression group was up-regulated compared to the normal group after i.t. or i.c.v. clonidine administration. Whereas the insulin level in depression group was not altered when mice were administered clonidine i.t. or i.c.v. Our results suggest that the blood glucose level in depression group is down-regulated compared to the normal group during d-glucose-fed-, immobilization stress-, and clonidine-induced hyperglycemia in mice. The down-regulation of the blood glucose level might be one of the important pathophysiologic changes in depression.

    The most common method used for minimizing the occurrence of diabetes complications is frequent glucose testing to adjust the insulin dose. However, using blood glucose (BG) meters presents a risk of infection. It is of great importance to develop non-invasive BG detection techniques. To realize high-accuracy, low-cost and continuous glucose monitoring, we have developed a non-invasive BG detection system using a mixed signal processor 430 (MSP430) microcontroller. This method is based on the combination of the conservation-of-energy method with a sensor integration module, which collects physiological parameters, such as the blood oxygen saturation (SPO2), blood flow velocity and heart rate. New methods to detect the basal metabolic rate (BMR) and BV are proposed, which combine the human body heat balance and characteristic signals of photoplethysmography as well dual elastic chambers theory. Four hundred clinical trials on real-time non-invasive BG monitoring under suitable experiment conditions were performed on different individuals, including diabetic patients, senior citizens and healthy adults. A multisensory information fusion model was applied to process these samples. The algorithm (we defined it as DCBPN algorithm) applied in the model combines a decision tree and back propagation neural network, which classifies the physiological and environmental parameters into three categories, and then establishes a corresponding prediction model for the three categories. The DCBPN algorithm provides an accuracy of 88.53% in predicting the BG of new samples. Thus, this system demonstrates a great potential to reliably detect BG values in a non-invasive setting.

We aimed to review the trials investigating the effects of SMBG in this population.Methods: Medline was searched until June 29, 2009. Randomized controlled trials (RCTs of at least 12 weeks’ duration were included. Data on the following aspects were gathered: patient and study characteristics, effects on HbA1c, quality of life and treatment satisfaction, and methodological quality.Results: The search revealed 9 original RCTs. These studies were very heterogeneous, and 5 were classified as of high quality. The studies with the best methodology did not show an effect of SMBG on HbA1c, the studies with the worst methodological quality did. Two out of the 4 studies that assessed quality of life showed a significant change in favor of the control group, 1 study showed a significant change in favor of SMBG.Discussion and conclusion: We found an inverse relation between study quality and efficacy of SMBG. At this moment, there is no basis for general use of SMBG in noninsulin-treated T2DM patients.Keywords: blood glucose self-monitoring, diabetes mellitus, type 2, blood glucose, hemoglobin A, glycosylated

    Full Text Available Anthropometric indexes such as body mass index (BMI, waist circumference (WC, hip ciucumference (HC, and waist–hip ratio (WHR, are all useful anthropometric measurements to provide important information on blood glucose concentrations. The aim of this study was to determine different anthropometric measurements, in particular BMI, waist circumference, hip circumference and waist-to-hip ratio, in their ability to predict the blood glucose levels in men and women 40 to 60. A cross-sectional study was conducted on a sample of 44 men and 127 women aged 40 to 50 who lived in Cipete Selatan subdistrict, South Jakarta. Blood glucose levels was assessed and anthropometric measurements comprising BMI, WC, HC, WHR were collected. Multiple linear regression analysis was used to determine the best predictor for blood glucose levels. The study showed that the prevalence of DM type 2 was 25.7% and the prevalence was higher in men (40.9% compared to women (23.5%. The significant predictive variables in the simple regression analysis were age and waist circumference. Multiple linear regression showed that after adjustment for age, WC was positively associated with blood glucose levels. Standardized a value was 0.172 (p=0.026. WC predict blood glucose levels, beyond that explained by traditional diabetic risk factors and BMI. These findings provide support for the recommendation that WC be a routine measure for identification of diabetes mellitus type 2 in men and women aged 40 to 60 years.

    Full Text Available Sappan wood or kayu secang (Caesalpinia sappan L. was reported of having medicinal properties, such as natural antioxidant, relieve vomiting of blood, and mix of ingredients for malaria drugs. The research was conducted to study the influence of ethanol extract from sappan wood on blood glucose level of white rats. The study of the blood glucose level in rats was carried out by using glucose tolerance method. It was measured by Refloluxs (Accutrend GC with Chloropropamide 50 mg/200 g BW (Body weight as positive control. The ethanol extracts were used in various concentrations 10, 20, 30, 40 and 50 mg/200 g BW per-oral and was observed every hour, beginning one hour before to 7 hours after the extract being administered. The results showed that treatment of ethanol extract of sappan wood by administer doses gave remarkable effect on the blood glucose level in white rat. It reduced the glucose level in the blood compared to the negative and positive control. Treatment of dose 30 mg/200 g BW gave similar effect to positive controls, while a dose of 50 mg/200 g BW gave lower blood glucose level (93 mg/dl than the positive controls.

    Full Text Available Barley (Hordeum vulgare L. is a well-known cereal plant. Young barley leaf is consumed as a popular green-colored drink, which is named “Aojiru” in Japan. We examined the effects of barley leaf powder (BLP and insoluble fibers derived from BLP on postprandial blood glucose in rats and healthy Japanese volunteers. BLP and insoluble fibers derived from BLP suppressed the increment of postprandial blood glucose levels in rats (, and increased the viscosity of their digesta. The insoluble fibers present in BLP might play a role in controlling blood glucose level by increasing digesta viscosity. In human, BLP suppressed the increment of postprandial blood glucose level only in those which exhibited higher blood glucose levels after meals (. BLP might suppress the increment of postprandial blood glucose level by increasing digesta viscosity in both of rats and humans who require blood glucose monitoring.

    Many species undergo natural fasts as part of their life histories. Extended fasting is associated with increased β-oxidation of fatty acids and reduced oxidation of glucose to minimize commitment of body protein to gluconeogenesis. However, the metabolic strategies used to sustain extended fasts simultaneous with high rates of energy expenditure are not well understood. Studies in fasting adult female and weanling northern elephant seals (NES) have revealed high rates of endogenous glucose production (EGP) under constraints of high nutrient demand for lactation or development but relatively low rates of metabolism. These studies revealed low rates of glucose oxidation and high rates of glucose recycling through the Cori cycle. We measured rates of glucose flux in fasting adult male NES to assess how significantly longer fasting durations, higher metabolic rates, and greater rates of muscular activity affect glucose kinetics. We measured glucose turnover in 18 adult males using the clearance of [6-H(3)] glucose during breeding and molting. Adult male NES maintain high rates of EGP across extended fasts. EGP greatly exceeded estimated needs for glucose-dependent tissues, varied directly with plasma insulin and lactate concentrations, and was inversely related to plasma ketoacid concentrations. Together, these findings suggest that high rates of glucose production and recycling during breeding maintain high blood glucose levels to support glucose-dependent tissues while minimizing production of ketoacids and commitment of protein stores to glucose production.

    Mobile phones are two-way radios that emit electromagnetic radiation in microwave range. As the number of mobile phone users has reached 6 billion, the bioeffects of exposure to mobile phone radiation and mobile phone electromagnetic interference with electronic equipment have received more attention, globally. As self-monitoring of blood glucose can be a beneficial part of diabetes control, home blood glucose testing kits are very popular. The main goal of this study was to investigate if radiofrequency radiation emitted from a common GSM mobile phone can alter the accuracy of home blood glucose monitors. Forty five female nondiabetic students aged 17-20 years old participated in this study. For Control-EMF group (30 students), blood glucose concentration for each individual was measured in presence and absence of radiofrequency radiation emitted by a common GSM mobile phone (HTC touch, Diamond 2) while the phone was ringing. For Control- Repeat group (15 students), two repeated measurements were performed for each participant in the absence of electromagnetic fields. The magnitude of the changes between glucose levels in two repeated measurements (|ΔC|) in Control-Repeat group was 1.07 ± 0.88 mg/dl while this magnitude for Control-EMF group was 7.53 ± 4.76 mg/dl (P < 0.001, two-tailed test). To the best of our knowledge, this is the first study to assess the electromagnetic interference in home blood glucose monitors. It can be concluded that electromagnetic interference from mobile phones has an adverse effect on the accuracy of home blood glucose monitors. We suggest that mobile phones should be used at least 50 cm away from home blood glucose monitors.

    Graphical abstract: -- Highlights: •Successfully synthesised highly-ordered gold nanowires array with an AAO template. •Fabricated an ultra-sensitive glucose nanobiosensor with the gold nanowires array. •Achieved sensitivity as high as 379.0 μA cm{sup −2} mM{sup −1} and detection limit as low as 50 nM. •Achieved excellent anti-interference with aid of Nafion membrane towards UA and AA. •Enabled successful detection and quantification of glucose in human blood serum. -- Abstract: A highly sensitive amperometric nanobiosensor has been developed by integration of glucose oxidase (GO{sub x}) with a gold nanowires array (AuNWA) by cross-linking with a mixture of glutaraldehyde (GLA) and bovine serum albumin (BSA). An initial investigation of the morphology of the synthesized AuNWA by field emission scanning electron microscopy (FESEM) and field emission transmission electron microscopy (FETEM) revealed that the nanowires array was highly ordered with rough surface, and the electrochemical features of the AuNWA with/without modification were also investigated. The integrated AuNWA–BSA–GLA–GO{sub x} nanobiosensor with Nafion membrane gave a very high sensitivity of 298.2 μA cm{sup −2} mM{sup −1} for amperometric detection of glucose, while also achieving a low detection limit of 0.1 μM, and a wide linear range of 5–6000 μM. Furthermore, the nanobiosensor exhibited excellent anti-interference ability towards uric acid (UA) and ascorbic acid (AA) with the aid of Nafion membrane, and the results obtained for the analysis of human blood serum indicated that the device is capable of glucose detection in real samples.

    We assessed the impact of thinking of a current romantic partner on acute blood glucose responses and positive affect over a short period of time. Participants in romantic relationships were randomly assigned to reflect on their partner, an opposite-sex friend, or their morning routine. Blood glucose levels were assessed prior to reflection, as well as at 10 and 25 min postreflection. Results revealed that individuals in the routine and friend conditions exhibited a decline in glucose over time, whereas individuals in the partner condition did not exhibit this decline (rather, a slight increase) in glucose over time. Reported positive affect following reflection was positively associated with increases in glucose, but only for individuals who reflected on their partner, suggesting this physiological response reflects eustress. These findings add to the literature on eustress in relationships and have implications for relationship processes.

    Non-invasive blood glucose determination has been investigated by more than 100 research groups in the world during the past fifteen years. The commonly optical methods are based on the capacity of near-IR light to penetrate a few hundreds micrometers or a few millimeters into human tissue where it interacts with glucose. A change of glucose concentration may modify the optical parameters in tissue, with the result that its glucose concentration can be extracted by analyzing the received optical signals. This paper demonstrates that glucose affects on the scattering coefficient of human blood, by applying the streak camera and pulsed photoacoustic techniques; and drinking water seems also affecting on PA signal from skin surface.

    We undertook the present study to examine the effect of the angiotensin-converting enzyme inhibitor enalapril, the angiotensin II antagonist losartan, and calcium antagonist verapamil on systolic pressure and spontaneous blood glucose levels in rats from the Cohen-Rosenthal diabetic hypertensive strain. Genetic hypertension and diabetes developed in this strain after crossbreeding of Cohen diabetic and spontaneously hypertensive rats. The new rat strain was fed their usual copper-poor sucrose diet, which is essential for the development of this model, and for 4 weeks received either enalapril, losartan, or verapamil. Systolic pressure was reduced significantly compared with controls in all treated groups. Chronic treatment with enalapril or verapamil, but not with losartan, succeeded in lowering spontaneous blood glucose, indicating improved diabetic control. Data suggest that angiotensin-converting enzyme inhibition by enalapril, but not angiotensin II antagonism by losartan, can improve glucose metabolism in addition to its hypotensive effect in a genetic diabetic hypertensive rat strain. This confirms that the drop in glucose with converting enzyme inhibition is highly dependent on bradykinin accumulation. Data further suggest that calcium channel blockade by verapamil can also improve glucose metabolism. The question remains whether the reduction in glucose by verapamil was a result of inhibition of glucogenesis.

    Full Text Available Background and Objective: Carbohydrates are considered as the major source of energy in physical activity. Studies show that consumption of carbohydrate foods before exercise can balance blood glucose and free fatty acids and increase athletes’ performance. In this study , we compared the effect of three kinds of foods with different glycemic indices on blood glucose (BG and serum free fatty acids (FFA in cycling ,male athletes. Material and Methods: In this clinical trial, 21 members of national cycling team randomly allocated to three equal groups of glucose (low glycemic index ، lentil (low glycemic index and potato (high glycemic index. First, Fasting blood samples (5ml were obtained to measure BG and FFA . Then the subjects were asked to eat their foods. After 45 mins of rest, they pedaled with maximal oxygen consumption VO2max for two hours and again their blood samples were taken to compare with the levels of before interventions. Results: Glucose consumption resulted in a significant decrease in FFA level after 2 hours of pedaling (P = 0.01 but no significant change in BG level. Plasma glucose was higher after eating lentil than that of potato (P<0.05, but it was not true for FFA level of both groups. Conclusion: Based on the results, the pre-exercise use of low glycemic index (lentil compared to high glycemic index (potato can better lead to increased blood glucose during exercise.

    Acute physiological stress has been shown to impair glucose homeostasis. War is a period of acute psychological stress, and its effect on glucose control is unknown. In this study random point-of-care (POC) glucose levels were measured using an automated, institutional glucometer in hospitalized adult patients prior to versus during the Israeli Pillar of Defense campaign (November 7-10, 2012). Random POC glucose values measured with the institutional blood glucose monitoring system were obtained 1 week prior to the Pillar of Defense campaign (November 7-10, 2012) and compared with values to those obtained during the first 4 days of the war (November 14-17, 2012). In total, 3,573 POC glucose measures were included: 1,865 during the pre-war period and 1,708 during the campaign. POC glucose measures were significantly higher during the war compared with the week preceding the war: 9.7±4.7 versus 9.3±4.2 mmol/L (P=0.02). In a general linear model, period (pre-war vs. during war) persisted as a significant predictor of POC glucose even after controlling for age, sex, and department type (internal medicine vs. surgical). Acute stress, such as a wartime situation, is associated with a significant increase in random blood glucose values in a population of hospitalized adults. Long-term follow-up of the individuals hospitalized during these two periods can reveal differences in morbidity and mortality trends.

    In this report, we present a paper membrane-based surface-enhanced Raman scattering (SERS) platform for the determination of blood glucose level using a nitrocellulose membrane as substrate paper, and the microfluidic channel was simply constructed by wax-printing method. The rod-shaped gold nanorod particles were modified with 4-mercaptophenylboronic acid (4-MBA) and 1-decanethiol (1-DT) molecules and used as embedded SERS probe for paper-based microfluidics. The SERS measurement area was simply constructed by dropping gold nanoparticles on nitrocellulose membrane, and the blood sample was dropped on the membrane hydrophilic channel. While the blood cells and proteins were held on nitrocellulose membrane, glucose molecules were moved through the channel toward the SERS measurement area. Scanning electron microscopy (SEM) was used to confirm the effective separation of blood matrix, and total analysis is completed in 5 min. In SERS measurements, the intensity of the band at 1070 cm(-1) which is attributed to B-OH vibration decreased depending on the rise in glucose concentration in the blood sample. The glucose concentration was found to be 5.43 ± 0.51 mM in the reference blood sample by using a calibration equation, and the certified value for glucose was 6.17 ± 0.11 mM. The recovery of the glucose in the reference blood sample was about 88 %. According to these results, the developed paper-based microfluidic SERS platform has been found to be suitable for use for the detection of glucose in blood samples without any pretreatment procedure. We believe that paper-based microfluidic systems may provide a wide field of usage for paper-based applications.

    A differential equation model is formulated that describes the dynamics of glucose concentration in blood circulation. The model accounts for the intake of food, expenditure of calories and the control of glucose levels by insulin and glucagon. These and other hormones affect the blood glucose level in various ways. In this study only main effects are taken into consideration. Moreover, by making a quasi-steady state approximation the model is reduced to a single nonlinear differential equation of which parameters are fit to data from healthy subjects. Feedback provided by insulin plays a key role in the control of the blood glucose level. Reduced β-cell function and insulin resistance may hamper this process. With the present model it is shown how by closed-loop control these defects, in an organic way, can be compensated with continuous infusion of exogenous insulin. PMID:28060898

    We focus on the research to develop a compact Self Monitoring of Blood Glucose (SMBG). The SMBG consists of (1) a micro electrical pumping system for blood extraction, (2) a painless microneedle as same size as a female mosquito's labium and (3) a biosensor to detect and evaluate an amount of glucose in extracted blood, by using enzyme such as glucose oxidase (GOx). A gold (Au) plate immobilized GOx was used as a biosensor and attached to the gate electrode of MOSFET. GOx was immobilized on a self-assembled spacer combined with an Au electrode by the cross-link method using BSA (bovine serum albumin) as an additional bonding material. The electrode could detect electrons generated by the hydrolysis of hydrogen peroxide produced by the reaction between GOx and glucose using the constant electric current measurement system of the MOSFET type hybrid biosensor system. The system can measure the change of gate voltage. The extracting speed for whole blood using the micro electrical pumping system was about 2 μl/min. The extracted volume was sufficient to determine the glucose level in the blood; it was comparable to the volume extracted in a commercial glucose level monitor. In the functional evaluation of the biosensor system using hydrogen peroxide solution, it is shown that the averaged output voltage increases in alignment to hydrogen peroxide concentration. The linear value was shown with the averaged output voltage in corresponding hydrogen peroxide concentration with the averaged output voltage obtained from the biosensor system by glucose solution concentration. Furthermore, it is confirmed that the averaged output voltage from the biosensor system obtained by whole blood showed the same voltage in corresponding glucose solution concentration. The hybrid biosensor obtained the useful performance for the SMBG.

    Previous studies have shown that a bout of moderate or light postprandial physical activity effectively blunts the postprandial increase in blood glucose. The objective of this study was to test whether regular light postprandial physical activity can improve glycemia in persons with hyperglycemia or with a high risk of hyperglycemia. We randomized 56 participants to an intervention or a control group. They were diagnosed as hyperglycemic, not using antidiabetics, or were categorized as high-risk individuals for type 2 diabetes. The intervention group was instructed to undertake a minimum 30 min of daily light physical activity, starting a maximum of 30 min after a meal in addition to their usual physical activity for 12 weeks. The control group maintained their usual lifestyle. Blood samples were taken pre- and post-test. Forty participants completed the study and are included in the results. The self-reported increase in daily physical activity from before to within the study period was higher in the intervention group compared with control (41 ± 25 vs. 2 ± 16 min, p < 0.001). Activity diaries and accelerometer recordings supported this observation. The activity in the intervention group started earlier after the last meal compared with control (30 ± 13 vs. 100 ± 57 min, p = 0.001). There were no within- or between-group differences in any glycemic variable from pre- to post-test. In conclusion, the present study does not seem to support the notion that regular light postprandial physical activity improves blood glucose in the long term in persons with hyperglycemia or with high risk of hyperglycemia.

    Background Hyperglycemia in brain and spinal cord could aggravate neurologic impairment. Recent studies showed that L-lysine monohydrochlonde (LMH) could increase the insulin secretion and regulate the blood glucose level. The aim of the present study was to investigate the effects of LMH on pancreatic islet B cells, the levels of endogenous insulin and blood glucose in spinal cord injured rats.Methods Forty male Wistar rats were divided into four groups, namely, normal control group, model group, high-dose LMH group (621.5 mg/kg equal to LMH 1/8 LD50), and low-dose LMH group (310.8 mg/kg equal to LMH 1/16 LD50). The model of spinal cord injured rat was established by hemi-transection at the lower right thoracic spinal cord. LMH was administered via intraperitoneal injection once spinal cord injury was produced in rats. All rats were sacrificed 48 hours after spinal cord injured. The effects of LMH on pancreatic islet B cells, the content of endogenous insulin, end the level of blood glucose were observed with immunohistochemical method, radioimmunoassay method, end biochemical analyzer, respectively. Results The insulin immunohistochemical intensities of islet B cells were significantly weaker in model group then those in normal control group (P 0.05). Conclusion LMH, but dose-dependent, might participate in the regulation of pancreatic islet B cells, and then reduce the blood glucose levels in the spinal cord injured rats.

    Background Extra glucose load in peritoneal dialysis is an important cause of newly-occurred diabetic mellitus, which initiates insulin treatment in some of the dialytic patients.The purpose of this study was to discuss the influence of the peritoneal transfer status on fasting blood glucose in non-diabetic nephropathy patients who are on continuous ambulatory peritoneal dialysis (CAPD).Methods One hundred and forty-five patients with total KT/V per week over 2.0 were recruited, including 60 males and 85 females. Fasting blood glucose (FBG), creatinine, blood urea nitrogen (BUN), blood albumin, blood lipid profile and blood C-reactive protein (CRP) were analyzed at the beginning of the peritoneal dialysis and after 12 months. A peritoneal equilibration test (PET) was carried out at the 3rd month of CAPD, and meantime residual renal function, peritoneal solute clearance rate, ultrafiltration volume and urine volume were also evaluated.Results Twenty-one cases were identified as a low transfer group (L), 32 cases as a low average transfer group (LA), 58 cases as a high average transfer group (HA) and 34 cases as a high transfer group (H). At the end of the 12th month, 83 cases had elevated FBG Through stepwise multiple regression analysis we found the FBG level in these patients was positively related to glucose load and CRP, and negatively related to glucose absorption in the peritoneum (D/D_0) and blood albumin (P<0.05). Kaplan-Meier analysis during a 48-month follow-up found the morbidity of hyperglycemia to be 17/34 cases (50.1%) in the high transfer group, 20/58 cases (34.5%) in the high average transfer group, 11/32 cases (34.3%) in the low average transfer group, and 1/21 cases (5.4%) in the low transfer group.Conclusions Patients with high peritoneal transfer capacity might have the highest morbidity from hyperglycemia among patients with these four different peritoneal transfer status. Glucose load, baseline CRP and FBG level before peritoneal dialysis, and

    Objective To discuss whether the capillary whole blood glucose (CBG) test can be used in glucose screening test (GST) for gestational diabetes mellitus (GDM) compared to the venous plasma glucose (VPG) method, and to determine the cutoff value of CBG. Methods This was a self-control test. The 50-g oral GST was conducted among 1 557 pregnant women between 24-28 weeks. Every woman was measured CBG and VPG at the same time and same arm. Three hundred and forty women underwent 100-g 3-h oral glucose tolerance test (OGTT). Receiver operation curve (ROC) was used to determine the potential cutoff level of CBG and VPG. Diagnose criteria of GDM was based on NDDG criteria. OGTT diagnosed GDM and VPG ≥ 7. 8 mmol/L were used as golden standard for ROC. Results There was good relationship between CBG and VPG ( P < 0.01 ). Correlation coefficient was 0. 86. The value of CBG was lower than VPG. The statistical and high-sensitivity cutoff values were 7. 4 mmol/L in CBG and 7. 8 mmol/L in VPG when GDM was used as golden standard. Cutoff value of CBG was 7. 0 mmol/L when VPG≥ 7. 8 mmol/L was used as golden standard. The pregnant outcomes of positive cases of three thresholds had no significant differences. But it was better in case of the pregnant woman when the CBG value was more than 7. 4 mmol/L. Conclusion CBG can be used in GST, the threshold of CBG was suggested as 7. 4 mmol/L. CBG test was more convenience and effective than VPG test.

    Objective:To observe the effect of mitiglinide combined laser photocoagulation on blood glucose, blood lipid and vascular endothelial function in diabetic retinopathy.Methods:A total of 106 patients with diabetic retinopathy treated in our hospital from January 2014 to January 2015 were selected and assigned into the separate group and combined group. Fifty-three patients in the separate group only received oral mitiginide, while other 53 patients in the combined group received oral mitiglinide and laster photocoagulation surgery. Before and after treatment, the FBG, 2hPBG, HbA1c, TC, TG, HDL-C, LDL-C, ET-1, VEGF, PEDF, ICAM-1, FMD of patients in the two groups were analyzed.Results: After treatment, the blood glucose and blood lipid indexes of patients in the two groups were improved significantly, and there was no statistical difference between the two groups. The ET-1, ICAM-1 and VEGF of patients in the two groups decreased, and the decrease of the combined group was more distinctly. The PEDF and FMD in the two groups all increased, and the combined group changed more obviously. The regression of the blood vessel and the recovery of visual acuity in the combined group were better than the separate group.Conclusions:Mitiglinide combined with laser photocoagulation can effectively improve the level of blood glucose and blood lipid, promote vascular endothelial function and inhibit the formation of retinal neovascularization so as to improve the visual acuity level.

    Full Text Available Background: Diabetes mellitus is a chronic disease with a worldwide prevalence and its complications can be prevented with close monitoring of blood glucose. Quality of blood glucose monitoring utilizing glucometers in Iranian hospitalized patients has not been well published in the literature. We evaluated the accuracy and consistency of the results of two devices compared with the standard laboratory method used for measuring glucose levels in a teaching hospital.Methods: In this study 100 patients with the average age of 57.5 ±17.7 years were randomly selected from 19 wards and their blood glucose were simultaneously measured using Accu-Chek Active®(1 and Cleverchek®(2 (commonly used in the wards and the conventional laboratory method. Calibration was performed on both devices.Results: Absolute Mean Difference of the devices 1 and 2 from the laboratory values were 24.3±2.4,and 38.5±4.5, respectively (P: 0.003. Correlation coefficient of the obtained values by glucometers1 and 2 with lab, were 0.82 and 0.52, respectively. Calibration of the devices showed that device 1 was the most consistent device with the laboratory values, and Pearson correlation coefficient between the obtained values as a result of four reiterations for each sample in each device showed that the highest coefficient belonged to the device 1 and the least belonged to the device 2 used in the Ear, Nose, and Throat Departments.Conclusion: The device 2 used in different wards of the hospital must be calibrated periodically. Furthermore, the device 1 generated closest results to the ones obtained through the laboratory.

    Diabetic retinopathy typically causes poor vision and blindness. A previous study revealed that a high blood glucose concentration induces glycoxidation and weakens the retinal capillaries. Nevertheless, the molecular mechanisms underlying the effects of high blood glucose induced diabetic retinopathy remain to be elucidated. In the present study, we cultured the retinal pigmented epithelial cell line ARPE-19 in mannitol-balanced 5.5, 25, and 100 mM glucose media and investigated protein level alterations. Proteomic analysis revealed significant changes in 137 protein features, of which 124 demonstrated changes in a glucose concentration dependent manner. Several proteins functionally associated with redox regulation, protein folding, or the cytoskeleton are affected by increased glucose concentrations. Additional analyses also revealed that cellular oxidative stress, including endoplasmic reticulum stress, was significantly increased after treatment with high glucose concentrations. However, the mitochondrial membrane potential and cell survival remained unchanged during treatment with high glucose concentrations. To summarize, in this study, we used a comprehensive retinal pigmented epithelial cell based proteomic approach for identifying changes in protein expression associated retinal markers induced by high glucose concentrations. Our results revealed that a high glucose condition can induce cellular oxidative stress and modulate the levels of proteins with functions in redox regulation, protein folding, and cytoskeleton regulation; however, cell viability and mitochondrial integrity are not significantly disturbed under these high glucose conditions.

    High blood glucose in patients with acute coronary syndromes have been associated with adverse short-term outcomes in patients without diabetes. However, the relation of admission glucose to long-term outcomes in these patients was less well established. Accordingly, consecutive patients with ST-elevation myocardial infarction (STEMI) without diabetes enrolled at 155 sites from July 2000 to November 2002 in the ACOS Registry were evaluated. Patients were categorized into tertiles based on admission blood glucose. Clinical end points of interest were 1-year mortality and composite of death, reinfarction, stroke, or rehospitalization (major adverse cardiac clinical events [MACCEs]) in the hospital and after discharge. Of 5,866 patients with STEMI, 36.9% had blood glucose 150 mg/dl. Admission blood glucose was significantly related to increased risk of not only in-hospital events (death, glucose >150 vs 150 vs 150 vs 150 vs <120 mg/dl, adjusted OR 1.31, 95% CI 1.00 to 1.71, p <0.0001). In conclusion, high blood glucose at admission to the hospital independently correlated with short- and midterm mortality in patients with STEMI.

    Around 308 million people worldwide are estimated to have impaired glucose tolerance (IGT); 25% to 75% of these will develop diabetes within a decade of initial diagnosis. At diagnosis, half will have tissue-related damage and all have an increased risk for coronary heart disease. The objective of this review was to assess the effects and safety of Chinese herbal medicines for the treatment of people with impaired glucose tolerance or impaired fasting glucose (IFG). We searched the following databases: The Cochrane Library, PubMed, EMBASE, AMED, a range of Chinese language databases, SIGLE and databases of ongoing trials. Randomised clinical trials comparing Chinese herbal medicines with placebo, no treatment, pharmacological or non-pharmacological interventions in people with IGT or IFG were considered. Two authors independently extracted data. Trials were assessed for risk of bias against key criteria: random sequence generation, allocation concealment, blinding of participants, outcome assessors and intervention providers, incomplete outcome data, selective outcome reporting and other sources of bias. This review examined 16 trials lasting four weeks to two years involving 1391 participants receiving 15 different Chinese herbal medicines in eight different comparisons. No trial reported on mortality, morbidity or costs. No serious adverse events like severe hypoglycaemia were observed. Meta-analysis of eight trials showed that those receiving Chinese herbal medicines combined with lifestyle modification were more than twice as likely to have their fasting plasma glucose levels return to normal levels (i.e. fasting plasma glucose lifestyle modification alone (RR 2.07; 95% confidence intervall (CI) 1.52 to 2.82). Those receiving Chinese herbs were less likely to progress to diabetes over the duration of the trial (RR 0.33; 95% CI 0.19 to 0.58). However, all trials had a considerable risk of bias and none of the specific herbal medicines comparison data was

    Local cerebral blood flow and glucose metabolism were examined in spontaneously epileptic El mice using autoradiography with {sup 125}I-IMP and {sup 14}C-DG in the interictal phase and during seizure. El (+) mice that developed generalized tonic-clonic convulsions and El (-) mice that received no stimulation and had no history of epileptic seizures were examined. The seizure non-susceptible, maternal strain ddY mice were used as control. Uptake ratios for IMP and DG in mouse brain were calculated using the autoradiographic density. In the interictal phase, the pattern of local cerebral blood flow of El (+) mice was similar to that of ddY and El (-) mice, and glucose metabolism in the hippocampus was higher in El (+) mice than in El (-) and ddY mice, but flow and metabolism were nearly matched. During seizure, no significant changed blood flow and increased glucose metabolism in the hippocampus, the epileptic focus, and no markedly changed blood flow and depressed glucose metabolism in other brain regions were observed and considered to be flow-metabolism uncoupling. These observations have never been reported in clinical or experimental studies of epilepsy. Seizures did not cause large regional differences in cerebral blood flow. Therefore, only glucose metabolism is useful for detection of the focus of secondary generalized seizures in El mice, and appeared possibly to be related to the pathophysiology of secondary generalized epilepsy in El mice.

    Full Text Available This study was carried out to investigate the blood glucose reducing effect (hypoglycemic effect of stem bark extract of Acacia polyacantha on normal wistar rats over a 24 h period. Three groups of previously fasted wistar rats, with each group made up of 5 rats each were administered with 100, 200 and 400 mg/kg p.o of aqueous methanolic stem bark extract of A. polyacantha. The hypoglycemic effect of A . polyacantha stem bark aqueous methanolic extract was compared with that of Metformin (250 mg/kg in fasted normal rats. Following treatment, relatively moderate to high doses of A. polyacantha (100, 200 and 400 mg/kg p.o. produced a dose-dependent, significant reduction (p<0.05 in blood glucose levels of fasted normal rats. The three doses of the extract did not significantly alter the blood glucose levels after 2 h of extract administration. After 8 and 16 h of extract administration at a dose of 200 mg/kg significantly (p<0.05 decreased the blood glucose levels when compared to control, while the dose of 400 mg/kg significantly decreased the blood glucose levels after 4, 8 and 16 h of extract administration when compared with the control group. The Preliminary phytochemical screening revealed the presence of alkaloids, tannins, flavonoids, triterpenoids, anthraquinones, steroids and saponins. The median lethal dose (LD50 in rats was calculated to be 3807.9 mg/kg body weight. In conclusion the aqueous methanolic extract of Acacia polyacantha possesses hypoglycemic activity in normoglycemic rats.

    Jifeng Zhang

    Full Text Available The prevalence of type 2 diabetes (T2D is rapidly increasing worldwide. Effective therapies, such as insulin and Glucagon-like peptide-1 (GLP-1, require injections, which are costly and result in less patient compliance. Here, we report the identification of a tripeptide with significant potential to treat T2D. The peptide, referred to as Diapin, is comprised of three natural L-amino acids, GlyGlyLeu. Glucose tolerance tests showed that oral administration of Diapin effectively lowered blood glucose after oral glucose loading in both normal C57BL/6J mice and T2D mouse models, including KKay, db/db, ob/ob mice, and high fat diet-induced obesity/T2D mice. In addition, Diapin treatment significantly reduced casual blood glucose in KKay diabetic mice in a time-dependent manner without causing hypoglycemia. Furthermore, we found that plasma GLP-1 and insulin levels in diabetic models were significantly increased with Diapin treatment compared to that in the controls. In summary, our findings establish that a peptide with minimum of three amino acids can improve glucose homeostasis and Diapin shows promise as a novel pharmaceutical agent to treat patients with T2D through its dual effects on GLP-1 and insulin secretion.

    Full Text Available Aims: The aim was to determine the effect of meal glycemic load (GL on blood glucose levels of healthy people with different body mass indexes (BMIs. Methods: Thirty healthy controls were included in this study. The participants were divided into two groups according to their BMI as normal group (BMI = 18.5–24.9 kg/m2, n = 15 and overweight group (BMI = 25.0–29.9 kg/m2, n = 15. Dietary assessment was done by the 24-h recall method for 3 successive days. Cases were fed by breakfasts with two different GL on consecutive days. Energy values of the test meal, adjusted to meet 25% of daily energy requirements of each case, were identical in low and high GL meal (483 kcal and 482 kcal, respectively. Finger-prick capillary blood samples were taken on 0, 15, 30, 45, 60, 90, and 120 min. Results: Average daily energy intake in normal and overweight group was found as 2514.3 ± 223.8 kcal, 2064.1 ± 521.6 kcal and 2211.4 ± 368.7 kcal, 2494.8 ± 918 kcal in males and females, respectively. Blood glucose level was increased and remained more stable in both high GL meal groups compared to low (P < 0.05. The effects of GL on BMI classified groups were also found different. High GL meal was found to be more effective for increasing blood glucose level, especially on overweight group (P < 0.05. Conclusions: The effects of GL meal were found to be different on normal and overweight individuals. The high GL meals were more effective to increase the blood glucose level than low GL meal, especially on overweight people.
