    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.

    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.

    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.

    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.

    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.)

    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.

    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.

    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 : 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.

    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.

    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.

  17. 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.

    Full Text Available "nThis study was conducted to determine the effect of Swedish massage on blood glucose level in children with diabetes mellitus (DM. It was prospective randomized controlled trial study that conducted on 36 children, 6-12 years old with DM, recruited from a hospital in Qom City, Iran. The children were randomly assigned to intervention and control groups. Swedish massage was performed 15 minutes, 3 times a week, for 3 months in intervention group. The blood glucose levels were evaluated immediately after every session of massage in two groups. The mean ages of children in the intervention (n=18 and control (n=18 groups were 9.05 ± 1.55 and 9.83 ±2.03 years respectively. There was statistically no significant difference in blood glucose levels before intervention between two groups (P=0.586, but the blood glucose levels were lower significantly in intervention group in comparison with control group after intervention (P<0.0001. Addition of Swedish massage to daily routines; exercise, diet and medication regimens, is an effective intervention to reduce blood glucose level in diabetic children.

    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.

    Introduction: Cardiopulmonary bypass (CPB) can cause stress response that increases levels of cytokine and catecholamine in plasma, resulting in hyperglycemia. In adults, it has been demonstrated that remifentanil infusion during CPB could prevent increases of cytokine, catecholamine, and blood glucose levels, but such effects of remifentanil in children have not been elucidated. Aim: In this study, we investigated the preventive effects of remifentanil on blood glucose and lactate levels during CPB in children. Materials and Methods: This retrospective study included children who underwent ventricular septal defect or atrial septal defect closure. Data for patients who did not receive, during CPB period, remifentanil infusion (non-Remi group) and patients who received remifentanil infusion at 0.5 μg/kg/min (Remi group) during CPB were used for analysis. Primary outcomes were lactate and blood glucose levels just before and after CPB. Data are presented as medians and interquartile ranges. Data were analyzed by the Mann–Whitney U-test and Chi-square test. A P < 0.05 was considered statistically significant. Results: During CPB, 13 and 11 patients were allocated into Remi and non-Remi groups, respectively. Pre-CPB lactate and blood glucose levels were not significantly different between the two groups, but post-CPB lactate and blood glucose levels in the Remi group were significantly lower than that in the non-Remi group. Conclusion: 0.5 μg/kg/min remifentanil infusion during CPB suppresses the increases of blood glucose and lactate levels in children. PMID:28074792

    Gordon, David M; Ash, Stephen R

    2009-01-01

    The purpose of this research project was to determine whether the glucose level of a blood plasma sample from a diabetic patient could be predicted by measuring the density and conductivity of ultrafiltrate of plasma created by a 30,000 m.w. cutoff membrane. Conductivity of the plasma filtrate measures electrolyte concentration and should correct density measurements for changes in electrolytes and water concentration. In vitro studies were performed measuring conductivity and density of solutions of varying glucose and sodium chloride concentrations. Plasma from seven hospitalized patients with diabetes was filtered across a 30,000 m.w. cutoff membrane. The filtrate density and conductivity were measured and correlated to glucose levels. In vitro studies confirmed the ability to predict glucose from density and conductivity measurements, in varying concentrations of glucose and saline. In plasma filtrate, the conductivity and density measurements of ultrafiltrate allowed estimation of glucose in some patients with diabetes but not others. The correlation coefficient for the combined patient data was 0.45 which was significant but only explained 20% of the variability in the glucose levels. Individually, the correlation was significant in only two of the seven patients with correlation coefficients of 0.79 and 0.88. The reasons for lack of correlation are not clear, and cannot be explained by generation of idiogenic osmoles, effects of alcohol dehydrogenase, water intake, etc. This combination of physical methods for glucose measurement is not a feasible approach to measuring glucose in plasma filtrate.

    Full Text Available In the present study we examined gross changes in the mass of whole adrenal glands and that of the adrenal cortex, as well as the serum corticosterone and glucose level of mature male Wistar rats subjected to three different treatments: animals subjected to chronic restraint-stress, animals injected with lithium (Li and chronically stressed rats treated with Li. Under all three conditions we observed hypertrophy of whole adrenals, as well as the adrenal cortices. Chronic restraint stress, solely or in combination with Li treatment, significantly elevated the corticosterone level, but did not change the blood glucose level. Animals treated only with Li exhibited an elevated serum corticosterone level and blood glucose level. The aim of our study was to investigate the modulation of the chronic stress-induced effect on the blood glucose level by lithium, as a possible mechanism of avoiding the damage caused by chronic stress. Our results showed that lithium is an agent of choice which may help to reduce stress-elevated corticosterone and replenish exhausted glucose storages in an organism.

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

    This study was evaluated the relationship between blood glucose levels and salivary pH and buffering capacity in type II diabetic patients. The sample comprised 210 participants (age ranged 40-60 years). Based on fasting blood glucose levels the participants were divided into 3 groups: controls with normal blood glucose levels; diabetic patients with levels ≤ 200 mg/dL; and diabetic patients with levels > 200 mg/dL. Salivary pH and buffering capacity were determined in a sample of resting (non-stimulated) saliva taken from each participant. Salivary pH levels in diabetic patients with blood glucose levels > 200 mg/dL were lower than in the controls and diabetic patients with levels ≤ 200 mg/dL. Salivary pH levels were comparable in controls and diabetic patients with blood glucose levels ≤ 200 mg/dL. Salivary buffering capacity in the 3 groups was comparable.

  7. Melatonin Signaling Controls the Daily Rhythm in Blood Glucose Levels Independent of Peripheral Clocks.

    Directory of Open Access Journals (Sweden)

    Full Text Available Melatonin is rhythmically secreted by both the pineal gland and retina in a circadian fashion, with its peak synthesis occurring during the night. Once synthesized, melatonin exerts its effects by binding to two specific G-protein coupled receptors-melatonin receptor type 1(MT1 and melatonin receptor type 2(MT2. Recent studies suggest the involvement of MT1 and MT2 in the regulation of glucose homeostasis; however the ability of melatonin signaling to impart timing cues on glucose metabolism remains poorly understood. Here we report that the removal of MT1 or MT2 in mice abolishes the daily rhythm in blood glucose levels. Interestingly, removal of melatonin receptors produced small effects on the rhythmic expression patterns of clock genes within skeletal muscle, liver, and adipose tissue. Taken together, our data suggest that the loss of the daily rhythm in blood glucose observed in MT1(-/- and MT2(-/- mice does not occur as a consequence of 'disrupted' clocks within insulin sensitive tissues. Finally our results highlight a diurnal contribution of melatonin receptor signaling in the daily regulation of blood glucose levels.

    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

    AIM: Hyperglycemia commonly seen in liver transplantation (LT) has often been attributed to the dextrose in the storage solution of blood transfusion products. The purpose of the study is to compare the changes of the blood glucose levels in transfused and non-transfused patients during LT. METHODS: A retrospective study on 60 biliary pediatric patients and 16 adult patients undergoing LT was carried out. Transfused pediatric patients were included in Group Ⅰ (GI), those not transfused in Group Ⅱ (GⅡ). Twelve adult patients were not given transfusion and assigned to Group Ⅲ (GⅢ); whereas, four adult patients who received massive transfusion were assigned to Group Ⅳ (GⅣ). The blood glucose levels, volume of blood transfused, and the volume of crystalloid infused were recorded, compared and analyzed. RESULTS: Results showed that the changes in bloodglucose levels during LT for both non-transfused and minimally transfused pediatric groups and non-transfused and massively-transfused adult groups were almost the same. CONCLUSION: We conclude that blood transfusion does not cause significant changes in the blood glucose levels inthis study.

    The paper presents an analytical model to estimate blood glucose level from measurements made non-invasively and in real time by an antenna strapped to a patient's wrist. Some promising success has been shown by the RIT ETA Lab research group that an antenna's resonant frequency can track, in real time, changes in glucose concentration. Based on an in-vitro study of blood samples of diabetic patients, the paper presents a modified Cole-Cole model that incorporates a factor to represent the change in glucose level. A calibration technique using the input impedance technique is discussed and the results show a good estimation as compared to the glucose meter readings. An alternate calibration methodology has been developed that is based on the shift in the antenna resonant frequency using an equivalent circuit model containing a shunt capacitor to represent the shift in resonant frequency with changing glucose levels. Work under progress is the optimization of the technique with a larger sample of patients.

    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.

    The association between oral contraceptives and the modification of corporal weight and body fat distribution is controversial. The characteristics of the menstrual cycle, lipids and glucose levels were also analyzed. Thirty women who received ethinylestradiol 0.035 mg and norethindrone 0.400 mg for one year were studied. The following variables were analyzed every 3 months: weight, body mass index (BMI), hip perimeter, waist perimeter, waist-hip ratio (WHR), duration of menstrual cycle, quantity of uterine bleeding, as well as blood levels of cholesterol, triglycerides and glucose. Waist and hip perimeters increased during the third evaluation; as well as the BMI starting from the second evaluation. The triglycerides levels rose from the first evaluation. No modifications were found in the WHR, glucose and cholesterol levels and the duration of the menstrual cycle, but the quantity of uterine bleeding decreased from the third month. The oral contraceptive significantly increased BMI and triglycerides level, but no changes were detected in body fat distribution, cholesterol and glucose levels. Uterine bleeding decreased from the first evaluation.

    Recently studies conducted in various parts of the world indicate short sleep duration as a novel risk factor for development of type 2 diabetes. However, ethnic differences exist in the etiopathogenesis of diseases, the current study was undertaken to study the effect of sleep duration on the blood glucose level of Gujarati Indian adolescents. A randomized, non-experimental, cross-sectional study was done on the voluntary participants n = 332 Gujarati adolescent boys and girls of age group 13-20 years studying at the schools and colleges in the Anand district. The participants were assessed for their sleep duration, body composition and blood glucose level. The sleep duration was reported by the subjects as the number of hours they slept on most of the nights in a week over the last one-year. The observations of the study were then analyzed after grouping them into: 1) Adequate sleep duration at night, ASDN (> or = 7 hrs) and 2) Inadequate sleep duration at night, ISDN (way ANOVA and post hoc Tuky-Krammer test were used for finding significant differences (P sleep duration at night (< 7 hrs) does not affect the blood glucose level of the Gujarati Indian adolescents of age group 13-20 years.

The purpose of this study was to examine the acute effects of traditional Japanese alcohol beverages on biochemical parameters, physical and emotional state, and sleep patterns. Methods. Six healthy subjects (three men and three women; age, 28.8 ± 9.5 years; body mass index, 21.4 ± 1.6 kg/m2 consumed three different types of alcohol beverages (beer, shochu, and sake, each with 40 g ethanol or mineral water with dinner on different days in the hospital. Blood samples were collected before and 1, 2, and 12 h after drinking each beverage, and assessments of physical and emotional state were administered at the same time. In addition, sleep patterns and brain waves were examined using polysomnography. Results. Blood glucose levels at 1 h and the 12-h area under the curve (AUC value after drinking shochu were significantly lower than that with water and beer. The 12-h blood insulin AUC value after drinking shochu was significantly lower than that with beer. Blood glucose × insulin level at 1 h and the 2-h blood glucose × insulin AUC value with shochu were significantly lower than that with beer. The insulinogenic indexes at 2 h with beer and sake, but not shochu, were significantly higher than that with water. The visual analogue scale scores of physical and emotional state showed that the tipsiness levels with beer, shochu, and sake at 1 h were significantly higher than that with water. These tipsiness levels were maintained at 2 h. The polysomnography showed that the rapid eye movement (REM sleep latency with shochu and sake were shorter than that with water and beer. Conclusions. Acute consumption of alcohol beverages with a meal resulted in different responses in postprandial glucose and insulin levels as well as REM sleep latency. Alcohol beverage type should be taken into

    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.

    Full Text Available Providing information is not enough to improve diabetic patient’s compliance and achieve goals of therapy. Patient’s good awareness as well as emotional and social supports from family and community may play an important role to improve their compliance and clinical outcomes. Therefore, diabetes support groups were developed and each support group consisted of two pharmacists, two nurses, diabetic patients and their family members. A total of 70 type 2 diabetic patient’s were enrolled and randomized into support group 1 and support group 2. Patients in the group 1 received information leaflets only, while patient in the group 2 received pharmacist counselling and information leaflets at each meeting. Patient’s awareness of diabetes and compliance with medications were assessed by a short questionnaire at baseline and final follow-up. Blood glucose and cholesterol levels were also evaluated in both groups. At the end of study, the overall patient’s awareness and compliance improved by 61.5%. The random and fasting blood glucose levels decreased over than 30% in the group 2 and around 14% in the group 1. This study reveals that collaboration between health care professionals and community in the diabetes support group might help diabetic patients to increase their knowledge and compliance with the diabetes therapy as well as glycaemic control.

  1. Hunger games: fluctuations in blood glucose levels influence support for social welfare.

    Aarøe, Lene; Petersen, Michael Bang

    2013-12-01

    Social-welfare policies are a modern instantiation of a phenomenon that has pervaded human evolutionary history: resource sharing. Ancestrally, food was a key shared resource in situations of temporary hunger. If evolved human psychology continues to shape how individuals think about current, evolutionarily novel conditions, this invites the prediction that attitudes regarding welfare politics are influenced by short-term fluctuations in hunger. Using blood glucose levels as a physiological indicator of hunger, we tested this prediction in a study in which participants were randomly assigned to conditions in which they consumed soft drinks containing either carbohydrates or an artificial sweetener. Analyses showed that participants with experimentally induced low blood glucose levels expressed stronger support for social welfare. Using an incentivized measure of actual sharing behavior (the dictator game), we further demonstrated that this increased support for social welfare does not translate into genuinely increased sharing motivations. Rather, we suggest that it is "cheap talk" aimed at increasing the sharing efforts of other individuals.

  6. A PI-fuzzy logic controller for the regulation of blood glucose level in diabetic patients.

    2006-01-01

    This manuscript investigates different fuzzy logic controllers for the regulation of blood glucose level in diabetic patients. While fuzzy logic control is still intuitive and at a very early stage, it has already been implemented in many industrial plants and reported results are very promising. A fuzzy logic control (FLC) scheme was recently proposed for maintaining blood glucose level in diabetics within acceptable limits, and was shown to be more effective with better transient characteristics than conventional techniques. In fact, FLC is based on human expertise and on desired output characteristics, and hence does not require precise mathematical models. This observation makes fuzzy rule-based technique very suitable for biomedical systems where models are, in general, either very complicated or over-simplistic. Another attractive feature of fuzzy techniques is their insensitivity to system parameter variations, as numerical values of physiological parameters are often not precise and usually vary from patient to another. PI and PID controllers are very popular and are efficiently used in many industrial plants. Fuzzy PI and PID controllers behave in a similar fashion to those classical controllers with the obvious advantage that the controller parameters are time dependant on the range of the control variables and consequently, result in a better performance. In this manuscript, a fuzzy PI controller is designed using a simplified design scheme and then subjected to simulations of the two common diabetes disturbances--sudden glucose meal and system parameter variations. The performance of the proposed fuzzy PI controller is compared to that of the conventional PID and optimal techniques and is shown to be superior. Moreover, the proposed fuzzy PI controller is shown to be more effective than the previously proposed FLC, especially with respect to the overshoot and settling time.

    Full Text Available Previous studies reported increased risk of cardiac events in subjects with fasting blood glucose (FBG levels lower than the diagnostic threshold of diabetes mellitus. However, whether increased cardiac events in those with upper normal FBG is secondary to the shift of their cardiac sympathovagal balance towards sympathetic predominance is unknown.To assess the association between FBG levels and cardiac autonomic modulation (CAM in euglycaemic healthy subjects based on heart rate variability (HRV derived indices.The study enrolled 42 healthy young adults. Following sociodemographic and clinical assessment, blood samples were collected to measure FBG levels.

Further researches are needed to set out the glycemic threshold beyond which further increase in glucose level readjusts sympathovagal balance

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

    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.

    In the present work we studied the effects of four alcoholic beverages on blood alcohol levels, plasma insulin concentrations and plasma glucose concentrations in men and women. The volunteers were healthy non-smokers and they were divided according to sex into two groups of ten individuals. The alcoholic beverages used in the study were beer, red wine, whisky and "cachaça". In men, ingestion of the distilled drinks promoted a spike in blood alcohol levels more quickly than ingestion of the fermented drinks. In women, beer promoted the lowest blood alcohol levels over the 6h of the experiment. Whisky promoted highest blood alcohol levels in both sexes. The ingestion of wine promoted a significant difference in relation to the blood alcohol concentration (BAC) as a function of gender. The ingestion of cachaça by women produced BAC levels significantly smaller than those obtained for wine.

    It has been reported that concentrations of several biomarkers in diabetics' breath show significant difference from those in healthy people's breath. Concentrations of some biomarkers are also correlated with the blood glucose levels (BGLs) of diabetics. Therefore, it is possible to screen for diabetes and predict BGLs by analyzing one's breath. In this paper, we describe the design of a novel breath analysis system for this purpose. The system uses carefully selected chemical sensors to detect biomarkers in breath. Common interferential factors, including humidity and the ratio of alveolar air in breath, are compensated or handled in the algorithm. Considering the intersubject variance of the components in breath, we build subject-specific prediction models to improve the accuracy of BGL prediction. A total of 295 breath samples from healthy subjects and 279 samples from diabetic subjects were collected to evaluate the performance of the system. The sensitivity and specificity of diabetes screening are 91.51% and 90.77%, respectively. The mean relative absolute error for BGL prediction is 21.7%. Experiments show that the system is effective and that the strategies adopted in the system can improve its accuracy. The system potentially provides a noninvasive and convenient method for diabetes screening and BGL monitoring as an adjunct to the standard criteria.

    A mid-infrared attenuated total reflection (ATR) spectroscopy system employing hollow optical fibers and a trapezoidal multi-reflection ATR prism has been developed to measure blood glucose levels. Using a multi-reflection prism brought about higher sensitivity, and the flat and wide contact surface of the prism resulted in higher measurement reproducibility. An analysis of in vivo measurements of human inner lip mucosa revealed clear signatures of glucose in the difference spectra between ones taken during the fasting state and ones taken after ingestion of glucose solutions. A calibration plot based on the absorption peak at 1155 cm(-1) that originates from the pyranose ring structure of glucose gave measurement errors less than 20%.

    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.

    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.

    Full Text Available Periodontal inflammation is a periodontal disorder of high prevalence in the population. Chronic periodontitis is associated with the accumulation of plaque and calculus as local factors, and systemic factors such an diabetes mellitus (DM and HIV infection. Cytokine, especially IL-1β as inflammatory mediator for periodontal disease, may directly stimulated iNOS (inducible nitric oxide synthase expression and NO (nitric oxide production by β-cells, resulting in NO-mediated β-cell damage. The leucotoxin and proteases produced by periodontal pathogens will induce chemotactic and phagocytotic defect; therefore causing decreased PMN phagocytotic function. Hyperglicemia which occurs in diabetic patients increases calcium influx to the cell, resulting in the increased cytosol’s calcium ([Ca 2+]i level and; therefore, resulting in dysfunction of PMN and impaired PMN phagocytotic function. Advanced glycosilation endproduct in NIDDM binds to monocytes resulting in the increase of pro-inflammatory cytokines (IL-1, TNFα and produces activation of macrophages and osteoclasts. Hyperglicemia activates diacyl glycerol (DAG-protein kinase C (PKC, thus increasing PGE2 and cytokine expression that induce inflammation and periodontal tissue destruction processes. Studies on the effect of scaling to remove calculus disposition on blood glucose control and cellular immune response in DM patient has never been carried out. The aim of the study was to analyze the effect of scaling as non-surgical periodontal therapy on immune response (IL-1β level and PMN phagocytotic function and blood glucose level of type 2 diabetic patients. Subjects were diabetic patients, 60 controlled-DM (CDM and 60 uncontrolled-DM (UCDM, in Metabolic-Endocrinology Clinic of Ciptomangunkusumo Hospital, aged 40-60 years. The subjects were divided into treatment (scaling and control group, and cellular immune response and diabetic status, before and 6 weeks after treatment were evaluated

    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.

    Full Text Available Introduction & Objective: Alpha amylase is the most important decomposing enzyme in starch. Digestion and absorption of starch in the intestine can be prevented and also the blood sugar levels can be controlled by restrain and control of alpha amylase. The aim of this study was to evaluate the effect of trans-chalcone on amylase activity, blood glucose and lipid levels in diabetic and non diabetic rats. Materials & Methods: This experimental study was conducted in 1388 at Tehran University of Medical Sciences. Sixty rats were randomly divided to ten equal groups: non diabetic control, diabetic control, four non diabetic experiments and four diabetic experiments. Control groups received grape seed oil and experimental groups received 2, 8,16 and 32 mg/kg of body weight in a period of 24 days with a gastric cannula. Blood sugar, every two days, serum insulin levels in days 0,12, and 24 and at the end of the experiment, lipoproteins and alpha amylase activity were measured.The data were analyzed by one way analysis of variance, ANOVA, followed by Turkey,s test with SPSS soft ware . Results: On average Chalcone reduced 25.5% of blood sugar in normal and diabetic rats. IT also decreased the serum insulin level. On average, chalcone decreased 34.9% of alpha amylase activity in normal and diabetic rats. Following disturbances in lipids metabolism caused by diabetes, this drug improved lipoproteins metabolism and reduced water, food and urine volume. Conclusion: This study shows that trans-Chalcone reduces blood sugar and body weight via inhibition of alpha amylas. Moreover, improvement of lipoprotein metabolism may happen via the inhibitory effect of this drug on hydroxyl methyl glutaryl -COA reductase and phosphodiesterase.

    Full Text Available Introduction: Physical activity has been recommended for patients with Type 2 Diabetes Mellitus (T2DM as it provides enormous physiological benefits by reducing the risk factors for development of complications, improves blood glucose control, overall health and quality of life. Formulation of an individualized exercise prescription based on exercise capacity and baseline plasma glucose levels is mandatory, as an exercise intensity which is considered moderate for one might turn out to be extremely rigorous for another patient with T2DM. Materials and Methods: The relationship between 6 minute walk test (6MWT & some correlates of T2DM was investigated in order to formulate an exercise prescription. This observational study of 102 T2DM patients from whom an informed consent was obtained, was conducted at the diabetic clinic of Sri Ramachandra medical college and research institute. The patients were instructed and made to perform a 6MWT according to ATS guidelines. The measurements included the 6-Minute Walk Distance (6MWD for exercise capacity and the T2DM correlates including age, gender, fasting blood glucose, post prandial blood glucose, HbA1C, duration of diabetes, BMI and waist hip ratio (WHR. Results: The relationships between the parameters were determined using Pearson’s correlation coefficient at a significance level of 0.05. The participants consisted of 55 males (53.1% & 47 females (46.1%. The mean 6MWD for males was 353.73±53.750mts & females was 317.55±58.037mts.The 6MWD correlated significantly (P 0.05 with WHR (r = 0.191 (females,r=-0.058 (males,duration of diabetes (r = -0.020 and age( r = -0.112. Conclusion: Thus low exercise capacity in patients with T2DM was associated with higher adiposity & poor glycaemic control. Therefore these factors should be given consideration when prescribing exercises for patients with T2DM in order to ensure safety and efficiency of the exercise session.

    Full Text Available Introduction: Diabetic people are more at risk of diseases such as vascular, kidneys and eye diseases, compared with normal people. Since Vit C competitively replaces glucose in most chemical reactions; so inhibit on non enzymatic glycosylation such as hemoglobin and lipoproteins, it seems that Vit C can be effective to prevent diabetic complications .In this study effect of Vit C supplements on blood sugar and fats level in type II diabetic patients was investigated. Methods: This study was conducted as a clinical trial using paired random sampling on 136 type II diabetic patients. At first, the patients weights, age, type of diet were recorded .Then their fasting blood glucose (FBS, glycosylated hemoglobin (HbAIC, Cholesterol, triglyceride, HDL and LDL were measured. After that the patients were divided in two randomized groups. The first group (control was subject of administration of Vit C supplement (1250 mg, 5 times a day, for a period of 3 months and the second group received placebo. Data were analyzed by paired t- test and SPSS Software. Results: In this study most of patients were women (62.2% of control group and 64.7% of placebo group. The mean age between the control group and placebo group were reported 51.2 ± 6.8 and 50.37± 9.71 years respectively. At the end of study , after 3 months of administration of Vit C supplement to control group, the mean concentration of FBS, LDL triglyceride Cholesterol and glycosylated hemoglobin has been reduced significantly with respect to the placebo group and the mean value of HDL has been increased as well. Conclusion: The finding shows that Vit C supplements might reduce the amount of glucose, lipids and glycosylated hemoglobin in patients with type 2 diabetes. Therefore, its consumption in diabetic patients can be recommended and as a result patient complications will be significantly reduced.

    Full Text Available Background: Morphine withdrawal usually results in undesired outcomes , despite partial benefits of alternative medication such as methadone, because of the lack of mental sedation during the withdrawal period, may not lead to the desired result. In this study, forced exercise by treadmill is used to manage morphine dependence in animal model. Materials and Methods: Forty adult male mice were divided into 5 groups, from which 4 groups became dependent by increasing daily doses of morphine for 6 days (20-45 mg/kg, SC. Afterwards, the animals were treated for 21 days by either of the following protocol: Positive control (dependent received once daily 45 mg/kg of morphine sulfate (SC for 21 day, group under treatment by clonidine (0.4 mg/kg, SC for 21 day group under treatment by forced exercise by treadmill for 21 day, group under treatment by combination of clonidine (0.4 mg/kg, SC and forced exercise by treadmill for 21day and the negative control group(independent received saline injection like other groups. Each of this administration was injected at 8 AM. Finally, in the test day (day 28, all animals received a single dose of naloxone (3 mg/kg, SC at 8 AM and then were observed for withdrawal signs, and Total Withdrawal Score (TWS was determined as described previously. After withdrawal sign evaluation for evaluation of stress level of dependent mice, blood cortisol and glucose level were measured in non-fasting situations well. Results: This study showed that TWS significantly decreased in all treatment groups in comparison with positive control group (P < 0.001. Moreover, blood cortisol and glucose level significantly decreased in group under treatment by clonidine (0.4 mg/kg and group under treatment by combination of clonidine (0.4 mg/kg and forced exercise by treadmill groups in comparison with control positive (dependent (P < 0.05. Conclusion: This study suggested that forced exercise can be useful as adjunct therapy in dependent people

    Full Text Available We examined resource allocation priorities in the framework of an updated Maslow hierarchy of fundamental human needs. In Experiment 1, the participants in the food abundance priming condition viewing photos of high-calorie food allocated more money to savings than to spending. However, the participants preferred spending to savings under the condition of mating availability priming with romantic photographs. In Experiment 2, before and after drinking either water or a sugary beverage, fasting participants rated photos of a conversation between a man and a woman. Water drinking lowered the rating scores of mating intentions as well as blood glucose (BG levels. The sugary drink buffered this decline in sexual perceptivity. Overall, the change in BG levels was positively associated with changes in the ratings of mating intentions but was not associated with other likelihood ratings. These results suggest that both external cues of food and mating resources and internal BG fluctuation regulate the cognitive priority of physiological needs versus mate acquisition and retention.

    Full Text Available Summary: The effects of the hydromethanolic  extract of Indigofera pulchra on blood glucose levels of alloxan induced and normoglycemic Wistar rats has been investigated. Three doses of the extract (250mg/Kg, 500mg/Kg and 1000mg/Kg were administered intraperitoneally. The dose of 1000mg/Kg of the extract did not significantly alter the blood glucose levels of Alloxan induced diabetic Wistar rats after 4, 8 and 24 hours of treatment. However, the doses of 500 mg/Kg of the extract did significantly (p<0.05 decrease the blood glucose levels of Alloxan diabetic Wistar rats at 4 and 24 hours while  the dose of 250 mg/Kg of the extract did significantly (p<0.05 decrease the blood glucose levels of Alloxan diabetic Wistar rats at 4, 8 and 24 hours. In normoglycemic rats, the dose of 1000mg/Kg of the extract significantly (p<0.05 decrease the blood glucose levels at 8 and 24 hours only. Also the dose of 500 mg/kg significantly (p<0.05 decrease the blood glucose levels at 24 hours while the dose of 250 mg/kg significantly (p<0.05 in the blood glucose levels at 8 and 24 hours. The phytochemical screening revealed the presences of tannins, saponins, flavonoids and steroids. The median lethal dose (LD50 in rats was calculated to be 2,154.1 mg/kg bodyweight. In conclusion, the doses of the extract has shown both significant (p<0.05 hypoglycemic and anti-hyperglycemic effects in Wistar rats.   Industrial relevance: The search for more effective and hypoglycemic agents has continue to be an area of research interest, because of the less side effects and easily affordable  medicinal plants has, when compared to the synthetic drugs. Indigofera pulchra is a very virgin plant and promising base on these current findings. The phytochemical screening revealed the present of phenolic compounds, tannins steroids, saponins and alkaloids. Elucidation of those secondary metabolites would be more effective in the treatment of this illness.

    We evaluated the correlations between BMI, fasting glucose, insulin, testosterone level, insulin resistance, and prostate size in non-diabetic benign prostatic hyperplasia (BPH) patients with normal testosterone levels. Data from 212 non-diabetic BPH patients with normal testosterone levels, who underwent transurethral resection of the prostate (TURP) due to medical treatment failure, were evaluated retrospectively. Patients with prostate specific antigen (PSA) levels of ≥ 3 ng/mL underwent multicore transrectal prostate biopsy before TURP to rule out prostate cancer. Patients with diabetes mellitus (DM) or serum testosterone levels of Prostate size correlated positively with age (r = 0.227, P 0.05). Testosterone level inversely correlated with BMI (r = -0.327, P prostate size, PSA, or fasting glucose level (each P > 0.05). Upon multiple adjusted linear regression analysis, prostate size correlated with elevated PSA (P prostate hyperplasia.

    Dietary fiber improves hyperglycemia in patients with type 2 diabetes through its physicochemical properties and possible modulation of gut hormone secretion, such as glucagon-like peptide 1 (GLP-1). We assessed the effect of dietary fiber-enriched cereal flakes (DC) on postprandial hyperglycemia and gut hormone secretion in patients with type 2 diabetes. Thirteen participants ate isocaloric meals based on either DC or conventional cereal flakes (CC) in a crossover design. DC or CC was provided for dinner, night snack on day 1 and breakfast on day 2, followed by a high-fat lunch. On day 2, the levels of plasma glucose, GLP-1, glucose-dependent insulinotropic polypeptide (GIP), and insulin were measured. Compared to CC, DC intake exhibited a lower post-breakfast 2-hours glucose level (198.5±12.8 vs. 245.9±15.2 mg/dL, P<0.05) and a lower incremental peak of glucose from baseline (101.8±9.1 vs. 140.3±14.3 mg/dL, P<0.001). The incremental area under the curve (iAUC) of glucose after breakfast was lower with DC than with CC (P<0.001). However, there were no differences in the plasma insulin, glucagon, GLP-1, and GIP levels. In conclusion, acute administration of DC attenuates postprandial hyperglycemia without any significant change in the representative glucose-regulating hormones in patients with type 2 diabetes (ClinicalTrials.gov. NCT 01997281).

    We investigated the glycemic index (GI) and the insulinemic index (II) of cake made from whole soy powder (SBC) and the suppressive effects of SBC on the postprandial blood glucose and insulin by other carbohydrate foods. Furthermore, breath hydrogen excretion was simultaneously investigated. Twenty subjects were given 114 g SBC, 144 g cooked paddy-rice, and 60 g SBC with 144 g cooked paddy-rice in random order using a within-subject, repeated-measures design. Blood and end-expiratory gas were collected at the indicated periods after ingestion. The GI and the II of SBC were 22+/-6 and 48+/-29, respectively. The elevation of blood glucose by cooked paddy-rice was significantly suppressed by the addition of 60 g SBC, although the insulin secretion did not decrease. Breath hydrogen excretion by the addition of SBC to 144 g cooked paddy-rice was not significantly increased in comparison with cooked paddy-rice alone. SBC was of low GI and low II, but the postprandial insulin secretion in response to cooked paddy-rice was not suppressed.

    Full Text Available This study was carried out to evaluate the hypoglycemic properties of the methanolic extract of Adansonia digitata fruit pulp on blood glucose. Forty eight of the rats were randomly distributed into six. Group one served as the normal control and Group two rats were administered with alloxan (150 mg/kg intraperitoneally and served as the diabetic control. Groups 3, 4 and 5 were intraperitoneally administered with alloxan (150 mg/kg and orally administered with methanolic extract of Adansonia digitata fruit pulp (100, 200 and 300 mg/kg once daily for 4weeks. Group six rats were intraperitoneally administered with alloxan (150 mg/kg and orally administered with chlorpropamide (84 mg/kg once daily for 4 weeks. The serum concentration of glucose of all the rats in each group was determined after the 14th and 28th dose of treatment. There was significant (p<0.001 reduction of serum glucose in the three groups of rats administered with methanolic extract of fruit pulp at second and fourth week of the treatment. The group of animal treated with chlorpropamide (84 mg/kg also showed significant (p<0.001 reduction of serum glucose compared to most effective dose of the methanolic extract (300 mg/kg during the second and fourth week of the treatment. The result of qualitative phytochemical analysis of methanolic extract of Adansonia digitata fruit pulp indicated the presence of glycosides, flavonoids, tannins, saponins, terpenoids and steroids. This result suggests that the methanolic fruit pulp extract of Adansonia digitata possess antidiabetic effect on alloxan induced diabetic rats.

    Nineteen patients with unilateral Ménière's disease, 20 with psychogenic dizziness, and 20 with recurrent vestibulopathy (diagnostic criteria in text of paper) were found to have normal five hour glucose tolerance tests, serum thyroxine and effective thyroid indices, and serologic tests for syphilis. Hypothyroidism and hypoglycemia were absent in all groups. An unexplained finding of each diagnostic group was significant increase of fasting blood glucose and insulin levels, and elevated insulin:glucose ratios, compared to a control group. There appears to be no diagnostic indication for performing these chemical and serologic studies in patients with unilateral Ménière's disease, psychogenic vertigo, or recurrent vestibulopathy. Reasons are given to support the view that recurrent vestibulopathy may be a specific vestibular disturbance.

    Full Text Available To evaluate the effects of inspiratory loading on blood flow of resting and exercising limbs in patients with diabetic autonomic neuropathy. Ten diabetic patients without cardiovascular autonomic neuropathy (DM, 10 patients with cardiovascular autonomic neuropathy (DM-CAN and 10 healthy controls (C were randomly assigned to inspiratory muscle load of 60% or 2% of maximal inspiratory pressure (PImax for approximately 5 min, while resting calf blood flow (CBF and exercising forearm blood flow (FBF were measured. Reactive hyperemia was also evaluated. From the 20 diabetic patients initially allocated, 6 wore a continuous glucose monitoring system to evaluate the glucose levels during these two sessions (2%, placebo or 60%, inspiratory muscle metaboreflex. Mean age was 58 ± 8 years, and mean HbA1c, 7.8% (62 mmol/mol (DM and DM-CAN. A PImax of 60% caused reduction of CBF in DM-CAN and DM (P<0.001, but not in C, whereas calf vascular resistance (CVR increased in DM-CAN and DM (P<0.001, but not in C. The increase in FBF during forearm exercise was blunted during 60% of PImax in DM-CAN and DM, and augmented in C (P<0.001. Glucose levels decreased by 40 ± 18.8% (P<0.001 at 60%, but not at 2%, of PImax. A negative correlation was observed between reactive hyperemia and changes in CVR (Beta coefficient = -0.44, P = 0.034. Inspiratory muscle loading caused an exacerbation of the inspiratory muscle metaboreflex in patients with diabetes, regardless of the presence of neuropathy, but influenced by endothelial dysfunction. High-intensity exercise that recruits the diaphragm can abruptly reduce glucose levels.

    Full Text Available The effect of kappa-carrageenan consumption on blood glucose level were studied on diabetic male wistar rat (Ratus norvegicus.The rats were made diabetic by aloxan injection, and then were given that a ration contains 5, 10, 15, 20% (w/w kappa-carrageenan, standard ration (negative control, and parental glibenklamid (positive control. The results showed that the standard ration could not reduce blood glucose from hyperglycemic to normal level, while the ration contained kappacarrageenan could. The higher kappa-carrageenan seaweed level in the ration has higher capacity to decrease blood glucose level. The ration containing 20% and 15% kappa-carrageenan could reduce blood glucose in 18 and 21 days, respectively.The effect of this ration was similar to that of glibenklamid which reduced blood glucose to normal level in 18 days. The ration containing 5 and 10% kappa-carrageenan could reduce blood glucose level; Blood glucose leve return to normal on the 21st day.

    Full Text Available This paper emphasizes on a method for designing digital PID controller based on Field Programmable Gate Array (FPGA device for regulating blood glucose level of type-I diabetic patients. The controller is tuned using Bergman Minimal model as a diabetic patient model in MATLAB and Simulink environment. The PID parameters are tuned using a genetic algorithm (GA. Because the speed of control systems has influence on their performance and stability, Field Programmable Gate Array (FPGA device is considered. A Simulink to FPGA flow is applied to the structure of PID controller with Xilinx blocks in Simulink. The results of blood glucose of two diabetic patient models using different quantization in bits are simulated. The results show that unsuitable number of bits cause hypoglycemia and increasing the peak of blood glucose in diabetic patients. System Generator and Integrated Software Environment (ISE are used for creating Bitstream file that can be downloaded into FPGA device. The results show that implementation of PID controller on FPGA using System Generator is compact and high speed and causes the designer can evaluate and implement different designs simply.

    Purpose: Fluorescence lifetime imaging ophthalmoscopy (FLIO) provides in vivo metabolic mapping of the ocular fundus. Changes in FLIO have been found in e.g. diabetes patients. The influence of short term metabolic changes caused by blood glucose level changes on is unknown. Aim of this work is the detection of short-term changes in fundus autofluorescence lifetime during an oral glucose tolerance test. Methods: FLIO was performed in 10 healthy volunteers (29+/-4 years, fasting for 12h) using a scanning laser ophthalmoscope (30° fundus, 34μm resolution, excitation with 473nm diode laser with 70 ps pulses at 80 MHz repetition rate, detection in two spectral channels 500-560nm (ch1) and 560-720nm (ch2) using the timecorrelated single photon counting method). The blood glucose level (BGL) was measured by an Accu-Chek® Aviva self-monitoring device. Before and after a glucose drink (300ml solution, containing 75g of glucose (Accu-Chek® Dextrose O.G.T.), BGL and FLIO were measured every 15min. The FLIMX software package was applied to compute the average fluorescence lifetime τ on the inner ring of the ETDRS grid using a modified 3-exponential approach. Results: The results are given as mean +/- standard deviation over all volunteers in ch1. Baseline measurement: BGL: 5.3+/-0.4 mmol/l, τ1: 49+/-6ps. A significant reduction (α=5% Wilcoxon rank-sum test) in τ1 is detected after 15min (BGL: 8.4+/-1.1 mmol/l, τ1: 44+/-5ps) and after 90min (BGL: 6.3+/-1.4 mmol/l, τ1: 41+/-5ps). Results of ch2 show smaller reductions in the fluorescence lifetimes over time.

    Reference intervals for pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors. Therefore, the aim of this study was to establish age-specific reference intervals of glucose and lipid levels among local school children. This was cross-sectional study, conducted among Saudi school children. Fasting blood samples were collected from 2149 children, 1138 (53%) boys and 1011 (47%) girls, aged 6 to 18 years old. Samples were analyzed on the Architect c8000 Chemistry System (Abbott Diagnostics, USA) for glucose, cholesterol, triglycerides, HDL and LDL. Reference intervals were established by nonparametric methods between the 2.5th and 97.5th percentiles. Significant differences were observed between boys and girls for cholesterol and triglycerides levels in all age groups (P < 0.02). Only at age 6-7 years and at adolescents, HDL and LDL levels were found to be significant (P < 0.001). No significant differences were seen in glucose levels except at age 12 to 13 years. Saudi children have comparable serum cholesterol levels than their Western counterparts. This may reflect changing dietary habits and increasing affluence in Saudi Arabia. Increased lipid screening is anticipated, and these reference intervals will aid in the early assessment of cardiovascular and diabetes risk in Saudi pediatric populations.

    Full Text Available Objectives : Clonidine, a known antihypertensive, is currently used for many purposes including diabetic gastroparesis, postmenopausal hot flushes, opioid/nicotine/alcohol withdrawal. Its effects on carbohydrate metabolism appear to be variable. Hence, the present study was undertaken to evaluate the influence of clonidine on euglycemic and alloxan -induced diabetic rats and its interaction with glibenclamide. Materials and Methods : Alloxan - induced (150 mg/kg, i.p diabetic rats were divided into six groups of six animals each. Group I - Normal Control; Group II - Nondiabetic + Clonidine (25 μg/kg; Group III - Diabetic Control; Group IV - Diabetic + Glibenclamide (5 mg/kg; Group V - Diabetic + Glibenclamide + Clonidine. All drugs were given orally once daily. Blood glucose was estimated from rat tail vein using glucometer before start of the experiment and at the end of 30 days. Results : After 30 days of treatment, clonidine (25 mg/kg produced significant hyperglycemia in both euglycemic and diabetic rats. It also reduced the hypoglycemic effect of glibenclamide in diabetic rats. Conclusion : The results of present study indicate that clonidine has hyperglycemic effect and it also interacts with glibenclamide to reduce its hypoglycemic activity. If these findings are true to human beings then clonidine should not be used in diabetic patients on sulfonylureas.

    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.

    Extensive research has shown that physical performance and recovery can be improved by maintaining or enhancing glucose availability. Carbogen(®) (Triarco Industries, Wayne, NJ, USA), a patented dietary fungal carbohydrase enzyme system, converts complex carbohydrates and fiber into simpler carbohydrates when ingested. Supplementing the enzymatic digestion of complex carbohydrates and fiber that may be digested very slowly or not at all in vivo may increase the availability of glucose. This may be reflected by increased absorption rates and higher measurable levels of whole blood glucose (WBG) that may be bioavailable for extended energy production. These preliminary investigations evaluate the ability of Carbogen to produce a rapid and more sustained increase in WBG levels when combined with a variety of food substrates commonly used by athletes and non-athletes to increase levels of physical activity. To investigate this, food substrates having a low, moderate, or high glycemic index (GI) with various amounts of total carbohydrates and dietary fiber were used. The individually tested substrates include soy nuts, cooked pasta, meal replacement bars, a nutrition shake, and a carbohydrate sports supplement. The investigations presented here consist of seven separate preclinical rat feasibility studies conducted over a period of approximately 12 months. The collective results presented here identify specific attributes of a category of food substrates common to sports nutrition enthusiasts that may significantly increase WBG levels over an extended time when dosed with Carbogen. Specifically, using Carbogen with a food substrate having a low or moderate GI and containing dietary fiber may increase the rate of glucose absorption and maintain significant increases in WBG levels.

    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

    Recent studies have demonstrated a scrutinized association of diabetes mellitus with depressive symptoms and major depression. Glycogen synthase kinase-3 (GSK-3) is a protein kinase enzyme constitutively active in non-stimulated cells and in multiple signalings. Independent lines of research provide a converging evidence for an involvement of GSK-3 in the regulation of behavior and hyperglycemia. The present study revealed that streptozotocin (STZ)-induced diabetic rats were found to show lengthened duration of immobility in the forced-swimming test (FST) and reduced locomotor and exploratory activities in the open-field test (OFT). Imipramine (15 mg/kg), Paroxetine (10 mg/kg) and lithium carbonate (36.94 mg/kg) for 14 days reduced immobility behavior in FST. Paroxetine and lithium carbonate increased the locomotor and exploratory activities, while imipramine decreased the locomotor activity in the OFT. Imipramine and lithium carbonate reduced the blood glucose level while paroxetine didn't alter it. STZ-induced diabetes increased GSK-3 gene expression which was determined using the reverse transcription-quantitative polymerase chain reaction test, while the three drugs decreased its expression. It can be concluded that lithium carbonate and imipramine can control both hyperglycemia and the associated symptoms of depression at the same time by inhibiting GSK-3 activity. On the other hand, paroxetine may only manage the depressive-like symptoms associated with diabetes through modulating the enzyme GSK-3, without changing blood glucose levels.

    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. PMID:27928503

    2001-01-01

    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.

    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.

    Older and even new antidepressants cause adverse effects, such as orthostatic hypotension, hyper- or hypoglycemia, liver injury or lipid disorders. In our previous experiments we showed significant antidepressant- and anxiolytic-like activities of dual 5-HT1A and 5-HT7 antagonists with α1-adrenolitic properties i.e. 1-[(2,6-dimethylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-14) and 1-[(2-chloro-6-methylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-15). Here, we evaluated the influence of chronic administration of HBK-14 and HBK-15 on blood pressure (non-invasive blood pressure measurement system for rodents), lipid profile (total cholesterol, low density lipoproteins—LDL, high density lipoproteins—HDL, triglycerides), glucose level, and liver enzymes activity (aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transferase). We determined potential antihistaminic (isolated guinea pig ileum) and antioxidant properties (ferric reducing ability of plasma–FRAP, non-protein thiols–NPSH, stable free radical diphenylpicrylhydrazyl—DPPH) cytotoxicity. Our experiments revealed that HBK-14 and HBK-15 did not influence blood pressure, lipid profile, glucose level or liver enzymes activity in rats after 2-week treatment. We also showed that none of the compounds possessed antioxidant or cytotoxic properties at antidepressant- and anxiolytic-like doses. HBK-14 and HBK-15 very weakly blocked H1 receptors in guinea pig ileum. Positive results of our preliminary experiments on the safety of HBK-14 and HBK-15 encourage further studies concerning their effectiveness in the treatment of depression and/or anxiety disorders.

    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.

    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.

    Full Text Available Introduction & Objective: In the context effect of metformin in patients with acute coronary syndrome, available evidence supports cardiac effect. Yet, there is doubt about continuation or discontinuation of metformin before major surgery. The aim of the present study is to determine the efficacy of continuing metformin in plasma glucose, renal function index, arterial PH in type II diabetic patients after coronary artery bypass graft surgery. Materials & Methods: In this clinical-experimental study, 90 type II diabetic patients with ASA class II admitted for CABG surgery in Hamadan Ekbatan Hospital were enrolled in the study in 2014 and were randomly assigned to two groups , one group treated with insulin and continued metformin and the other group treated with insulin and discontinued metformin.In the beginning indicators such as age, sex, body mass index (BMI were compared which were not significantly different in the two groups. Then, other parameters such as blood glucose, BUN, Cr, arterial blood PH, cardiac arrhythmia and need for inotrope were compared. Used inotropes in this study included dopamine, dobutamine, epinephrine, norepinephrine, milrinon to achieve systolic blood presser pressure over 100mmHg. Results: Average plasma BUN after surgery and one day after surgery in the group who discontinued metformin significantly were higher compared with the metformin group, but no differences were observed in average plasma BUN in the 2nd and 3rd days after surgery in the two groups. During 3 days after surgery, average plasma creatinine was significantly lower in metformin group compared to non- metformin group. Although there was no difference between the two groups in pH parameter before surgery but in the metformin group, average pH was lower than non-metformin group after surgery.

    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.

    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...

      为研究黄粉虫脱脂粉对糖尿病小鼠血糖水平和高脂饮食小鼠血脂水平的影响,以ICR小鼠为实验动物,分别给糖尿病模型和高脂饮食小鼠饲料中添加20%、10%、5%剂量黄粉虫脱脂粉,另设对照组;分别于喂养第10天和第20天测定其空腹血糖水平,喂养结束后测定其空腹血脂水平。结果表明:黄粉虫脱脂粉不能降低糖尿病小鼠血糖值;而5%剂量黄粉虫脱脂粉即可有效预防高脂饮食小鼠血中胆固醇和甘油三酯含量的升高。%To explore the effects of fatless Tenebrio molitor Linneeus powder on blood glucose level in diabetic mice and blood lipid level in mice fed by high fat diet, fatless Tenebrio molitor Linneeus powder of 20%, 10%and 5%dose was mixed into the feed of ICR mice which had been diabetes model or were fed on high fat diet. The mice in another group were treated differently as control. Then the blood glucose level on empty stomach of the mice was determined in the 10th day and the 20th day and the blood lipid level on empty stomach in the end of the trail. Results:The funtion of Tenebrio molitor Linneeus powder to dropping blood glucose level of diabetic mice could not appear. But 5%dose of Tenebrio molitor Linneeus powder could restrain evidently the rising of TC and TG content in blood of the mice.

    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 Diets high in calories and sweetened foods with disaccharides frequently lead to exaggerated postprandial spikes in blood glucose. This state induces immediate oxidant stress and free radicals which trigger oxidative stress-linked diabetic complications. One of the therapeutic approaches for decreasing postprandial hyperglycemia is to retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes,α-amylase and α-glucosidases, in the digestive organs. Therefore, the inhibitory activity of Korean onion (Allium cepa L. extract against rat intestinal α-glucosidases, such as sucrase, maltase, and porcine pancreatic α-amylase were investigated in vitro and in vivo. The content of quercetin in ethyl alcohol extract of onion skin (EOS was 6.04 g/100 g dried weight of onion skin. The in vitro half-maximal inhibitory concentrations (IC50 of EOS and quercetin, a major phenolic in onion, on rat intestinal sucrase were 0.40 and 0.11 mg/mL, respectively. The postprandial blood glucose lowering effects of EOS and quercetin were compared to a known type 2 diabetes drug (Acarbose, a strong α-glucosidase inhibitor in the Sprague-Dawley (SD rat model. In rats fed on sucrose, EOS significantly reduced the blood glucose spike after sucrose loading. The area under the blood glucose-time curve (AUClast in EOS-treated SD rats (0.5 g-EOS/kg was significantly lower than in untreated SD rats (259.6 ± 5.1 vs. 283.1 ± 19.2 h·mg/dL. The AUClast in quercetin-treated SD rats (0.5 g-quercetin/kg was similar to in EOS-treated group (256.1 ± 3.2 vs. 259.6 ± 5.1 h·mg/dL. Results from this study indicates that although quercetin does have blood glucose lowering potential via α-glucosidase inhibition, there are other bioactive compounds present in onion skin. Furthermore, the effects of two weeks administration of EOS in a high carbohydrate-dietary mixture (Pico 5053 on sucrase and maltase activities in intestine were evaluated in SD rat model

    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.

    Full Text Available Safety and anti-diabetic effects of Glucolevel, a mixture of dry extract of leaves of the Juglans regia L, Olea europea L, Urtica dioica L and Atriplex halimus L were evaluated using in vivo and in vitro test systems. No sign of toxic effects (using LDH assay were seen in cultured human fibroblasts treated with increasing concentrations of Glucolevel. Similar observations were seen in vivo studies using rats (LD50: 25 g/kg. Anti-diabetic effects were evidenced by the augmentation of glucose uptake by yeast cells (2-folds higher and by inhibition of glucose intestinal absorption (∼49% in a rat gut-segment. Furthermore, treatment with Glucolevel of Streptozotocin-induced diabetic rats for 2–3 weeks showed a significant reduction in glucose levels [above 400 ± 50 mg/dl to 210 ± 22 mg/dl (P < 0.001] and significantly improved sugar uptake during the glucose tolerance test, compared with positive control. In addition, glucose levels were tested in sixteen human volunteers, with the recent onset of type 2 diabetes mellitus, who received Glucolevel tablets 1 × 3 daily for a period of 4 weeks. Within the first week of Glucolevel consumption, baseline glucose levels were significantly reduced from 290 ± 40 to 210 ± 20 mg/dl. At baseline, a subgroup of eleven of these subjects had glucose levels below 300 mg% and the other subgroup had levels ≥ 300 mg%. Clinically acceptable glucose levels were achieved during the 2–3 weeks of therapy in the former subgroup and during the 4th week of therapy in the latter subgroup. No side effect was reported. In addition, a significant reduction in hemoglobin A1C values (8.2 ± 1.03 to 6.9 ± 0.94 was found in six patients treated with Glucolevel. Results demonstrate safety, tolerability and efficacy of herbal combinations of four plants that seem to act differently but synergistically to regulate glucose-homeostasis.

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

    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.

    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.

    This study aimed to investigate the independent and joint association of blood pressure (BP), homocysteine (Hcy), and fasting blood glucose (FBG) levels with brachial-ankle pulse wave velocity (baPWV, a measure of arterial stiffness) in Chinese hypertensive adults.The analyses included 3967 participants whose BP, Hcy, FBG, and baPWV were measured along with other covariates. Systolic BP (SBP) was analyzed as 3 categories (SBP < 160 mmHg; 160 to 179 mmHg; ≥ 180 mmHg); Hcy as 3 categories (< 10 μmol/L; 10 to 14.9 μmol/L; ≥ 15.0 μmol/L) and FBG: normal (FBG < 5.6 mmol/L), impaired (5.6 mmol/L ≤ FBG < 7.0 mmol/L), and diabetes mellitus (FBG ≥ 7.0 mmol/L). We performed linear regression analyses to evaluate their associations with baPWV with adjustment for covariables.When analyzed individually, BP, Hcy, and FBG were each associated with baPWV. When BP and FBG were analyzed jointly, the highest baPWV value (mean ± SD: 2227 ± 466 cm/s) was observed in participants with FBG ≥ 7.0 mmol/L and SBP ≥ 180 mmHg (β = 432.5, P < 0.001), and the lowest baPWV value (mean ± SD: 1692 ± 289 cm/s) was seen in participants with NFG and SBP < 160 mmHg. When Hcy and FBG were analyzed jointly, the highest baPWV value (2072 ± 480 cm/s) was observed in participants with FBG ≥ 7.0 mmol/L and Hcy ≥ 15.0 μmol/L (β = 167.6, P < 0.001), while the lowest baPWV value (mean ± SD: 1773 ± 334 cm/s) was observed in participants with NFG and Hcy < 10 μmol/L.In Chinese hypertensive adults, SBP, Hcy, and FBG are individually and jointly associated with baPWV.Our findings underscore the importance of identifying individuals with multiple risk factors of baPWV including high SBP, FBG, and Hcy.

    {sup 18}F-FDG PET is increasingly used for imaging of vessel wall inflammation. However, limited data are available on the impact of methodological variables, i.e. prescan fasting glucose, FDG circulation time and injected FDG dose, and of different FDG uptake parameters, in vascular FDG PET imaging. Included in the study were 195 patients who underwent vascular FDG PET/CT of the aorta and the carotids. Arterial standardized uptake values ({sub mean}SUV{sub max}), target-to-background ratios ({sub mean}TBR{sub max}) and FDG blood-pool activity in the superior vena cava (SVC) and the jugular veins (JV) were quantified. Vascular FDG uptake values classified according to the tertiles of prescan fasting glucose levels, the FDG circulation time, and the injected FDG dose were compared using ANOVA. Multivariate regression analyses were performed to identify the potential impact of all variables described on the arterial and blood-pool FDG uptake. Tertile analyses revealed FDG circulation times of about 2.5 h and prescan glucose levels of less than 7.0 mmol/l, showing a favorable relationship between arterial and blood-pool FDG uptake. FDG circulation times showed negative associations with aortic{sub mean}SUV{sub max} values as well as SVC and JV FDG blood-pool activity, but positive correlations with aortic and carotid{sub mean}TBR{sub max} values. Prescan glucose levels were negatively associated with aortic and carotid{sub mean}TBR{sub max} and carotid{sub mean}SUV{sub max} values, but were positively correlated with SVC blood-pool uptake. The injected FDG dose failed to show any significant association with vascular FDG uptake. FDG circulation times and prescan blood glucose levels significantly affect FDG uptake in the aortic and carotid walls and may bias the results of image interpretation in patients undergoing vascular FDG PET/CT. The injected FDG dose was less critical. Therefore, circulation times of about 2.5 h and prescan glucose levels less than 7.0 mmol

    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.

    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.

    目的:了解抑郁症患者糖脂代谢以及应激情况。方法68例抑郁症患者作为抑郁症组,分别采用汉密顿抑郁量表(HAMD17)和汉密顿焦虑量表(HAMA14)、生活事件量表(LES)对患者情绪状况以及应激状况进行评定,监测其空腹血糖(FBG)、甘油三脂(TG)、血清总胆固醇(TC)、皮质醇(CO)水平,与40例对照组进行比较。结果抑郁症组的FBG、TG、CO水平显著高于对照组(P0.05);同时相关分析发现,抑郁症患者LES总分与FBG、CO水平呈正相关(P0.05). The results of related analysis showed that LES score of depression patients was positively correlated with levels of FBG and CO (P<0.05 or P<0.01), and the HAMA score, mental anxiety factors score and physical anxiety factors score were all positively correlated with level of TG. Conclusion The abnormal glucolipid metabolism of depression patients is related with their long-term mental stimulation. Therefore, clinicians ought to take early monitor on the patients’blood glucose, blood lipid and cortisol so as to provide timely treatment.

    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.

    Diabetes Mellitus (DM) is a widespread disease and a serious public health problem. Low Level LASER Therapy (LLLT) has been found to reduce glycaemia on DM type 1 patients, an observation requiring further research especially as regards characteristics of treatment protocol. The purpose of this work is to continue the line of research and propose a specific protocol for LLLT use. In spring 2008 a 48 year old man, DM type 1 insulin dependent patient has been submitted to 810 nm wavelength LLLT treatment in specific body areas daily for 3 weeks and then once a week for 4 weeks until normalization of glycaemia. Medical supervision was present before, during and after application. Insulin was reduced progressively and then stopped. A gradual reduction of glycaemia was noted during the course of treatment. In successive follow-ups a reduction in HbA1c was noted. Results confirm previous observations and need for further research on large cohorts. The indication that LASER may become a valuable addition to DM type 1 treatment is confirmed and the proposed protocol appears to be effective. The case presented merits review since it reports a therapeutic challenge, contributes to advance in medical science and spawns research.

    veis intraoperatórios mais elevados de glicemia estão associados com maior morbidade no pós-operatório de cirurgia cardíaca pediátrica.BACKGROUND: Anesthesia for pediatric cardiac surgery is systematically performed in severely ill patients under abnormal physiological conditions. In the intraoperative period, there are significant variations in blood volume, body temperature, plasma composition, and tissue blood flow, in addition to activation of inflammation, with important consequences. Serial measurements of blood glucose levels can indicate states of exacerbation of the neuroendocrine-metabolic response to trauma, serving as prognostic markers of morbidity in that population. OBJECTIVE: To correlate perioperative blood glucose levels of children undergoing cardiac surgery with the occurrence of postoperative complications, and to compare intraoperative blood glucose levels according to perioperative conditions. METHODS: Information regarding the surgical/anesthetic procedure and perioperative conditions of patients was collected from the medical records. The mean perioperative blood glucose levels in the groups of patients with and without postoperative complications and the frequencies of perioperative conditions were compared by use of odds ratio and non-parametric univariate analyses. RESULTS: Higher intraoperative blood glucose levels were observed in individuals who had postoperative complications. Prematurity, age group, type of anesthesia, and character of the procedure did not influence the mean intraoperative blood glucose level. The use of extracorporeal circulation (ECC was associated with higher blood glucose levels during surgery. In procedures with ECC, higher blood glucose levels were observed in individuals who had infectious and cardiovascular complications. In surgeries without ECC, that association was observed with infectious and hematological complications. CONCLUSION: Higher intraoperative blood glucose levels are associated with higher morbidity

    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.

    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

    Reactive hypoglycemia induced by late dumping syndrome is often observed after gastrectomy. However, no effective therapy has yet been fully established. We herein describe a case in which concurrent therapy with a low-carbohydrate diet using low-glycemic-index food and an alpha-glucosidase inhibitor, miglitol, very effectively ameliorated the postprandial fluctuations in the blood glucose and plasma insulin levels in a patient with reactive hypoglycemia due to late dumping syndrome following total gastrectomy. The administration of miglitol under a low-carbohydrate diet using low-glycemic-index food may therefore be an ideal treatment for reactive hypoglycemia due to late dumping syndrome.

    Blood glucose values close to normal reduce the microvascular complications of insulin-dependent diabetes mellitus. The Stockholm study of this effect continued after the initial 7.5-year period in order to see what happened when intensively treated patients were left to control their own treatment while treatment was intensified in the control group. Forty-three patients with insulin-dependent diabetes randomised to intensified conventional treatment (ICT) and 48 patients randomised to standard treatment (ST) were followed-up for 10 years. Vascular complications, treatment side-effects and well-being were studied. Risk factors for complications were sought. HbA1c (normal range 3.9-5.7%) was reduced from 9.5 +/- 1.4% (mean +/- SD) in the ICT group and 9.4 +/- 1.2% in the ST group to a mean (during 10 years) of 7.2 +/- 0.6% and 8.3 +/- 1.0%, respectively (p < 0.001). Serious retinopathy (63 vs 33%, p = 0.003), nephropathy (26 vs 7%, p = 0.012) and symptoms of neuropathy (32 vs 14%, p = 0.041) were more common in the ST group after 10 years. HbA1c and age were the only risk factors for complications. Self-reported well-being increased to a greater degree and severe hypoglycaemia was more common in the ICT group. Cognitive function after 10 years was similar in both treatment groups, and was not related to the number of severe hypoglycaemic episodes. Intensified insulin treatment leads to reduced long-term complications and increased well-being without causing undue side-effects.

    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.

    Over 90% of lead in blood is bound to the erythrocytes. This high affinity of lead for red cells may mean that chronic blood loss is a significant means for excretion of lead. This study sought correlations between blood lead levels and clinical conditions involving chronic blood loss. During May, June and July, 146 patients with normal hematocrits and red cell indices were identified from the hospital and clinic populations. For each patient, age, race, sex and medical history were noted, and a whole blood sample was analyzed by flameless atomic absorption spectrophotometry. Age-and race-matched pairs showed a significant correlation of chronic blood loss with lead levels. Patients with the longest history of blood loss (menstruating women) had the lowest level (mean 6.13 ..mu..g/dl, range 3.6-10.3 ..mu..g/dl). Post-menopausal women had levels (7.29 ..mu..g/dl, 1.2-14 ..mu..g/dl) comparable to men with peptic ulcer disease, or colon carcinoma (7.31 ..mu..g/dl, 5.3-8.6 ..mu..g/dl). The highest levels were among men who had no history of bleeding problems (12.39 ..mu..g/dl, 2.08-39.35 ..mu..g/dl). Chronic blood loss may be a major factor responsible for sexual differences in blood lead levels. Since tissue deposition of environmental pollutants is implicated in diseases, menstruation may represent a survival advantage for women.

    Yadav, Jyoti; Rani, Asha; Singh, Vijander

    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.

    Recent technological advancements in the photonics industry have led to a resurgence of interest in optical glucose sensing and to realistic progress toward the development of an optical glucose sensor. Such a sensor has the potential to significantly improve the quality of life for the estimated 16 million diabetics in this country by making routine glucose measurements more convenient. Currently over 100 small companies and universities are working to develop noninvasive or minimally invasive glucose sensing technologies, and optical methods play a large role in these efforts. It has become overwhelmingly clear that frequent monitoring and tight control of blood sugar levels are requisite for effective management of Diabetes mellitus and reduction of the complications associated with this disease. The pain and trouble associated with current "finger-stick" methods for blood glucose monitoring result in decreased patient compliance and a failure to control blood sugar levels. Thus, the development of a convenient noninvasive blood glucose monitor holds the potential to significantly reduce the morbidity and mortality associated with Diabetes. A method and apparatus for noninvasive measurement of blood glucose concentration based on transilluminated laser beam via the Index Finger has been reported in this paper. This method depends on photodiode based laser operating at 632.8 nm wavelength. During measurement, the index finger is inserted into the glucose sensing unit, the transilluminated optical signal is converted into an electrical signal, compared with the reference electrical signal, and the obtained difference signal is processed by signal processing unit which presents the results in the form of blood glucose concentration. This method would enable the monitoring blood glucose level of the diabetic patient continuously, safely and noninvasively..

    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.

    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

    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.

    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.

    Full Text Available Objectives: To study the correlation between blood glucose levels and salivary glucose levels in type 2 diabetic patients, to study the relationship between salivary glucose levels and oral candidal carriage in type 2 diabetic patients and to determine whether salivary glucose levels could be used as a noninvasive tool for the measurement of glycemic control in type 2 diabetics. Study Design: The study population consisted of three groups: Group 1 consisted of 30 controlled diabetics and Group 2 consisted of 30 uncontrolled diabetics based on their random nonfasting plasma glucose levels. Group 3 consisted of 30 healthy controls. Two milliliters of peripheral blood was collected for the estimation of random nonfasting plasma glucose levels and glycosylated hemoglobin (HbA1c. Unstimulated saliva was collected for the estimation of salivary glucose. Saliva was collected by the oral rinse technique for the estimation of candidal counts. Results: The salivary glucose levels were significantly higher in controlled and uncontrolled diabetics when compared with controls. The salivary candidal carriage was also significantly higher in uncontrolled diabetics when compared with controlled diabetics and nondiabetic controls. The salivary glucose levels showed a significant correlation with blood glucose levels, suggesting that salivary glucose levels can be used as a monitoring tool for predicting glycemic control in diabetic patients. Conclusion: The present study found that estimation of salivary glucose levels can be used as a noninvasive, painless technique for the measurement of diabetic status of a patient in a dental set up. Increased salivary glucose levels leads to increased oral candidal carriage; therefore, oral diagnosticians are advised to screen the diabetic patients for any oral fungal infections and further management.

    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.

    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.

    Full Text Available Abstract Background Reductions in postprandial glycemia have been demonstrated previously with the addition of the novel viscous polysaccharide (NVP, PolyGlycopleX® (PGX®, to an OGTT or white bread. This study explores whether these reductions are sustained when NVP is added to a range of commonly consumed foods or incorporated into a breakfast cereal. Methods Ten healthy subjects (4M, 6F; age 37.3 ± 3.6 y; BMI 23.8 ± 1.3 kg/m2, participated in an acute, randomized controlled trial. The glycemic response to cornflakes, rice, yogurt, and a frozen dinner with and without 5 g of NVP sprinkled onto the food was determined. In addition, 3 granolas with different levels of NVP and 3 control white breads and one white bread and milk were also consumed. All meals contained 50 g of available carbohydrate. Capillary blood samples were taken fasting and at 15, 30, 45, 60, 90 and 120 min after the start of the meal. The glycemic index (GI and the glycemic reduction index potential (GRIP were calculated. The blood glucose concentrations at each time and the iAUC values were subjected to repeated-measures analysis of variance (ANOVA examining for the effect of test meal. After demonstration of significant heterogeneity, differences between individual means was assessed using GLM ANOVA with Tukey test to adjust for multiple comparisons. Results Addition of NVP reduced blood glucose response irrespective of food or dose (p Conclusion Sprinkling or incorporation of NVP into a variety of different foods is highly effective in reducing postprandial glycemia and lowering the GI of a food.

    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.

    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.:

    2016-03-01

    In this work we have focused on the inhibition of three different enzymes with a role in postprandial glucose management: α-amylase, α-glucosidase and dipeptidyl peptidase 4. The assortment of 29 monomeric phenolic compounds was first screened at a single concentration. Next, the IC50 values of tested compounds were evaluated for compounds that considerably inhibited any of the enzymes. Nordihydroguaiaretic acid, a phenolic compound abundant in Creosote bush Larrea tridentata, possessed inhibitory activity for all tested enzymes. This in vitro mechanism of action supports traditional use of Creosote bush in diabetes treatment.

    Abstract Recent studies demonstrated an adverse effect of chronic exposure to air pollution (AP) on metabolic syndrome and its components. In a population-based study, we investigated the association between exposure to ambient AP and serum glucose (SG), among subjects with normal glucose, impaired fasting glucose (IFG), and diabetes mellitus (DM). We included 1,063,887 SG tests performed in 131,882 subjects (years 2001–2012). Exposure data included daily levels of SO2, NO2 and other pollutants of industrial, traffic, and nonanthropogenic sources. Demographical, clinical, and medications purchase data were assessed. Log-transformed SG levels were analyzed by linear mixed models adjusted for seasonal variables and personal characteristics. SG increases (%increase [95% CI]), among subjects with normal glucose, IFG, and DM, respectively, were associated with 6.36 ppb increase of NO2 measured 24 to 72 hours before the test (0.40% [0.31%; 0.50%], 0.56% [0.40%; 0.71%], and 1.08% [0.86%; 1.29%]); and with 1.17 ppb increase of SO2 measured 24 hours before the test (0.29% [0.22%; 0.36%], 0.20% [0.10%; 0.31%], and 0.33% [0.14%; 0.52%]). Among DM population, weakest association was observed among patients treated with Metformin (0.56% increase in SG [0.18%; 0.95%]). In conclusion, NO2 and SO2 exposure is associated with small but significantly increased levels of SG. Although DM patients were found to be more susceptible to the AP induced SG variations, Metformin treatment seem to have a protective effect. Given the chronic lifetime exposure to AP and the broad coverage of the population, even small associations such as those found in our study can be associated with detrimental health effects and may have profound public health implications.

    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.

    Full Text Available Glucose mobilization and utilization in the periphery and central nervous system are important during exercise and are responsible for exercise efficacy. Magnesium (Mg is involved in energy production and plays a role in exercise performance. This study aimed to explore the effects of Mg on the dynamic changes in glucose and lactate levels in the muscle, blood and brain of exercising rats using a combination of auto-blood sampling and microdialysis. Sprague-Dawley rats were pretreated with saline or magnesium sulfate (MgSO4, 90 mg/kg, i.p. 30 min before treadmill exercise (20 m/min for 60 min. Our results indicated that the muscle, blood, and brain glucose levels immediately increased during exercise, and then gradually decreased to near basal levels in the recovery periods of both groups. These glucose levels were significantly enhanced to approximately two-fold (P<0.05 in the Mg group. Lactate levels in the muscle, blood, and brain rapidly and significantly increased in both groups during exercise, and brain lactate levels in the Mg group further elevated (P<0.05 than those in the control group during exercise. Lactate levels significantly decreased after exercise in both groups. In conclusion, Mg enhanced glucose availability in the peripheral and central systems, and increased lactate clearance in the muscle during exercise.

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

    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.

    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.

    To explore the possibility of lanthanides as the enhancer of insulin absorption, the promoting effects of lanthanide ions on the absorption of intrapulmonary delivered insulin and reduction of blood glucose were investigated by means of two approaches, preadministration and coadministration of lanthanide ions with insulin. The results indicate that, compared with the results of those given insulin only, lanthanide ions can effectively enhance the level of insulin and the reduction of glucose level in blood. These effects are dependent on lanthanide species and their concentrations. The mechanism was discussed.

    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.

    The effect of 3-O-methyl-D-chiro-inositol (D-pinitol), purified from soybean, on the postprandial blood glucose response in patients with type 2 diabetes mellitus was examined. Fifteen Korean subjects with type 2 diabetes mellitus (seven men, eight women; 60.3 +/- 3.1 years old) ingested cooked white rice containing 50 g of available carbohydrate with or without prior ingestion of soy pinitol. Pinitol was given either as a 1.2 g dose at 0, 60, 120, or 180 minutes prior to rice ingestion, or as a 0.6 g dose at 60 minutes prior to rice ingestion. Capillary blood glucose levels were monitored for 4 hours after rice consumption. The ingestion of 1.2 g of pinitol 60 minutes prior to rice consumption controlled postprandial capillary blood glucose most effectively, significantly diminishing the postprandial increase in plasma glucose levels measured at 90 and 120 minutes after rice consumption (P pinitol and rice was significantly lower than that for subjects who consumed only rice (P pinitol had no apparent effect on postprandial insulin levels. Therefore, soybean-derived pinitol may be useful in controlling postprandial increases in blood glucose in patients with type 2 diabetes.

    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.

  13. A signal processing application for evaluating self-monitoring blood glucose strategies in a software agent model.

    2015-07-01

    We propose the signal processing technique of calculating a cross-correlation function and an average deviation between the continuous blood glucose and the interpolation of limited blood glucose samples to evaluate blood glucose monitoring frequency in a self-aware patient software agent model. The diabetic patient software agent model [1] is a 24-h circadian, self-aware, stochastic model of a diabetic patient's blood glucose levels in a software agent environment. The purpose of this work is to apply a signal processing technique to assist patients and physicians in understanding the extent of a patient's illness using a limited number of blood glucose samples. A second purpose of this work is to determine an appropriate blood glucose monitoring frequency in order to have a minimum number of samples taken that still provide a good understanding of the patient's blood glucose levels. For society in general, the monitoring cost of diabetes is an extremely important issue, and these costs can vary tremendously depending on monitoring approaches and monitoring frequencies. Due to the cost and discomfort associated with blood glucose monitoring, today, patients expect monitoring frequencies specific to their health profile. The proposed method quantitatively assesses various monitoring protocols (from 6 times per day to 1 time per week) in nine predefined categories of patient agents in terms of risk factors of health status and age. Simulation results show that sampling 6 times per day is excessive, and not necessary for understanding the dynamics of the continuous signal in the experiments. In addition, patient agents in certain conditions only need to sample their blood glucose 1 time per week to have a good understanding of the characteristics of their blood glucose. Finally, an evaluation scenario is developed to visualize this concept, in which appropriate monitoring frequencies are shown based on the particular conditions of patient agents. This base line can

    In recent years, the number of patients with type 2 diabetes mellitus caused by insulin resistance has continued to increase in Japan. Insulin resistance is considered to be closely related to the risk of cardiovascular diseases and atherosclerotic diseases, represented by arteriosclerosis obliterans (ASO). Therefore, improvement of insulin resistance is one of the important strategies in the treatment of type 2 diabetes mellitus. At present, α-glucosidase inhibitors, incretin-related drugs, and thiazolidinediones are among the most important oral hypoglycemic drugs used to improve insulin resistance. In this study, the effect of beraprost sodium, a prostaglandin I2 derivative, in the treatment of type 2 diabetes mellitus was investigated. In type 2 diabetic patients with ASO who were under treatment with pioglitazone, additional treatment with beraprost sodium exerted a significant synergistic effect in reducing the serum HbA1c levels as compared to treatment with pioglitazone alone. This result indicates that concomitant administration of pioglitazone and beraprost sodium may be useful in the treatment of diabetes -mellitus.

    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.

    Objective To explore the correlation between serum vitamin D level and fasting blood glucose in males without diabetes. Methods A retrospective study was performed on 620 cases of male patients examined in No. 306 hospital of PLA from January to December in 2013. Clinical index such as serum 25-hydroxy vitamin D[25(OH)D] level and fasting blood glucose(FBG)were exam-ined and analized. Based on the level of serum 25 ( OH ) D, all the participants were divided into the lowest 25 ( OH ) D tertile group(19. 00~41. 98 nmol/L),the middle tertile group(41. 99~58. 00 nmol/L)and the highest 25(OH)D tertile group(58. 01~142. 00 nmol/L).

    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.

    It is well established that animals including humans attribute greater reinforcing value to glucose-containing sugars compared to their non-caloric counterparts, generally termed 'artificial sweeteners'. However, much remains to be determined regarding the physiological signals and brain systems mediating the attribution of greater reinforcing value to sweet solutions that contain glucose. Here we show that disruption of glucose utilization in mice produces an enduring inhibitory effect on artificial sweetener intake, an effect that did not depend on sweetness perception or aversion. Indeed, such an effect was not observed in mice presented with a less palatable, yet caloric, glucose solution. Consistently, hungry mice shifted their preferences away from artificial sweeteners and in favour of glucose after experiencing glucose in a hungry state. Glucose intake was found to produce significantly greater levels of dopamine efflux compared to artificial sweetener in dorsal striatum, whereas disrupting glucose oxidation suppressed dorsal striatum dopamine efflux. Conversely, inhibiting striatal dopamine receptor signalling during glucose intake in sweet-naïve animals resulted in reduced, artificial sweetener-like intake of glucose during subsequent gluco-deprivation. Our results demonstrate that glucose oxidation controls intake levels of sweet tastants by modulating extracellular dopamine levels in dorsal striatum, and suggest that glucose utilization is one critical physiological signal involved in the control of goal-directed sweetener intake.

    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.

    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.

    Diabetes is one of the most debilitating and costly diseases currently plaguing humanity. It is a leading cause of death and dismemberment in the world, and we know how to treat it. Accurate, continuous monitoring and control of blood glucose levels via insulin treatments are widely known to mitigate the majority of detrimental effects caused by the disease. The primary limitation of continuous glucose monitoring is patient non-compliance due to the unpleasant nature of "finger-stick" testing methods. This limitation can be largely, or even completely, removed by non-invasive testing methods. In this report, we demonstrate the vibrational overtone circular dichroism properties of glucose and analyze its use as a method of non-invasive glucose monitoring, capable of assuaging this trillion dollar scourge.

    Disclosed is a method of producing cones and pillars on polymethylmethacralate (PMMA) optical fibers for glucose monitoring. The method, in one embodiment, consists of using electron beam evaporation to deposit a non-contiguous thin film of aluminum on the distal ends of the PMMA fibers. The partial coverage of aluminum on the fibers is randomly, but rather uniformly distributed across the end of the optical fibers. After the aluminum deposition, the ends of the fibers are then exposed to hyperthermal atomic oxygen, which oxidizes the areas that are not protected by aluminum. The resulting PMMA fibers have a greatly increased surface area and the cones or pillars are sufficiently close together that the cellular components in blood are excluded from passing into the valleys between the cones and pillars. The optical fibers are then coated with appropriated surface chemistry so that they can optically sense the glucose level in the blood sample than that with conventional glucose monitoring.

    Full Text Available Background: Hypoglycemia is one of the most common neonatal disorders, associated with severe complications. There has been a great deal of controversy regarding the definition and screening of hypoglycemia. Therefore, in this study, we aimed to determine a cut-off value for blood glucose level in glucometer readings. Methods: This cross-sectional study was conducted on 238 newborns at risk of hypoglycemia, admitted to Baqiyatallah Hospital of Tehran, Iran in 2012; the subjects were selected via simple sampling. After obtaining informed consents from the newborns’ parents, 1 cc blood samples were sent to the laboratory for measuring the blood glucose level. Moreover, venous blood samples, as well as heel-stick blood samples, were obtained for glucometer measurements. Blood glucose measurements were used to determine the cut-off value by the receiver operating characteristic (ROC curve and make comparisons with the diagnostic criteria for hypoglycemia in the literature. Results: A total of 238 infants with the mean weight of 2869±821.9 g were enrolled in this study. The mean (±SD blood glucose levels were 65.1±22.9, 82.9±24.7, and 84.4±24.8 mg/dl, based on the standard laboratory method, glucometer reading of venous blood samples, and glucometer reading of heel-stick capillary blood samples, respectively. The optimal cut-off point for hypoglycemia was determined as 65 mg/dl, using glucometer-based assessment of heel-stick blood samples. Conclusion: The significant difference in blood glucose levels measured by the laboratory method and outpatient glucometer readings highlights the importance of a cut-off value for rapid assessment and control of blood glucose and timely detection of hypoglycemia. In fact, the cut-off value introduced in the present study could facilitate such measurements.

    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.

    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.

    2007-11-01

    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.

    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.

    Abstract Background To examine the blood glucose profile and the relationship between blood glucose levels and neurodevelopmental outcome in term infants with hypoxic-ischaemic encephalopathy. Methods Blood glucose values within 72 hours of birth were collected from 52 term infants with hypoxic-ischaemic encephalopathy. Hypoglycaemia [< 46.8 mg\\/dL (2.6 mmol\\/L)] and hyperglycaemia [> 150 mg\\/dL (8.3 mmol\\/L)] were correlated to neurodevelopmental outcome at 24 months of age. Results Four fifths of the 468 blood samples were in the normoglycaemic range (392\\/468:83.8%). Of the remaining 76 samples, 51.3% were in the hypoglycaemic range and (48.7%) were hyperglycaemic. A quarter of the hypoglycaemic samples (28.2%:11\\/39) and a third of the hyperglycaemic samples (32.4%:12\\/37) were recorded within the first 30 minutes of life. Mean (SD) blood glucose values did not differ between infants with normal and abnormal outcomes [4.89(2.28) mmol\\/L and 5.02(2.35) mmol\\/L, p value = 0.15] respectively. In term infants with hypoxic-ischaemic encephalopathy, early hypoglycaemia (between 0-6 hours of life) was associated with adverse outcome at 24 months of age [OR = 5.8, CI = 1.04-32)]. On multivariate analysis to adjust for grade of HIE this association was not statistically significant. Late hypoglycaemia (6-72 hours of life) was not associated with abnormal outcome [OR = 0.22, CI (0.04-1.14)]. The occurrence of hyperglycaemia was not associated with adverse outcome. Conclusion During the first 72 hours of life, blood glucose profile in infants with hypoxic-ischaemic encephalopathy varies widely despite a management protocol. Early hypoglycaemia (0-6 hours of life) was associated with severe HIE, and thereby; adverse outcome.

    BACKGROUND: To examine the blood glucose profile and the relationship between blood glucose levels and neurodevelopmental outcome in term infants with hypoxic-ischaemic encephalopathy. METHODS: Blood glucose values within 72 hours of birth were collected from 52 term infants with hypoxic-ischaemic encephalopathy. Hypoglycaemia [< 46.8 mg\\/dL (2.6 mmol\\/L)] and hyperglycaemia [> 150 mg\\/dL (8.3 mmol\\/L)] were correlated to neurodevelopmental outcome at 24 months of age. RESULTS: Four fifths of the 468 blood samples were in the normoglycaemic range (392\\/468:83.8%). Of the remaining 76 samples, 51.3% were in the hypoglycaemic range and (48.7%) were hyperglycaemic. A quarter of the hypoglycaemic samples (28.2%:11\\/39) and a third of the hyperglycaemic samples (32.4%:12\\/37) were recorded within the first 30 minutes of life. Mean (SD) blood glucose values did not differ between infants with normal and abnormal outcomes [4.89(2.28) mmol\\/L and 5.02(2.35) mmol\\/L, p value = 0.15] respectively. In term infants with hypoxic-ischaemic encephalopathy, early hypoglycaemia (between 0-6 hours of life) was associated with adverse outcome at 24 months of age [OR = 5.8, CI = 1.04-32)]. On multivariate analysis to adjust for grade of HIE this association was not statistically significant. Late hypoglycaemia (6-72 hours of life) was not associated with abnormal outcome [OR = 0.22, CI (0.04-1.14)]. The occurrence of hyperglycaemia was not associated with adverse outcome. CONCLUSION: During the first 72 hours of life, blood glucose profile in infants with hypoxic-ischaemic encephalopathy varies widely despite a management protocol. Early hypoglycaemia (0-6 hours of life) was associated with severe HIE, and thereby; adverse outcome.

    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.

    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.

    Objective: To probe glycemic excursions in type 2 diabetic patients whose hemoglobin A1c (HbA1c) was kept ≤6.0%.Methods: Totally 36 cases with type 2 diabetes (T2DM) with HbA1c≤6.0% and 30 cases with normal glucose tolerance (NGT) from December 2005 to December 2007 in our department were subjected prospectively. Continuous glucose monitoring system (CGMS) was employed to record their continuous blood glucose level for 3 d. The blood glucose profiles including the mean blood glucose (MBG), standard differentiation (SD), mean amplitude of glycemic excursions (MAGE) and absolute means of daily differences (MODD) were analyzed. Results: T2DM group had obviously postprandial hyperglycemia, in about 2 h after meal, especially after breakfast. Fifty-two hypoglycemic episodes occurred during the monitoring period in T2DM groups, of which 73.1% (38 episodes) were absence of symptomatic hypoglycemia with the lowest value of blood glucose only 2.0 mmol/L. And 20 episodes took place during the day hours, while 32 episodes observed during the night hours. Compared with NGT groups, SD, MAGE and MODD were all significantly higher in T2DM groups. MBG was significantly correlated with HbA1c in T2DM groups, but SD, MAGE, NGE and MODD were all independent of HbA1c. MAGE was independent of MODD. Conclusion: The amplitude of glycemic excursions is higher in normol-controlled T2DM groups than the NGT groups.Thus ideally glycemic control is not only to make HbA1c reach standard, but also to lessen glycemic excursions and reduce hypoglycemia episodes.

    Full Text Available Objective  To study the hypoglycemic effect and insulin sensitization mechanism of ophiopogonis tuber extracts on the 3T3-L1-induced adipocytes, and also in rats with reproduction of type 2 diabetes mellitus (T2DM. Methods  3T3-L1 cells were induced and differentiated into adipocytes. After the intervention with ophiopogonpolysaccharide (OPSR and ophiopogonin (OPG, glucose consuming rate was detected for screening the extracts which may have effective hypoglycemic effects. The insulin resistance (IR adipocyte model was established by dexamethasone induction, and then it was treated with OPSR. The protein expression levels of leptin, adiponectin and resistin were detected by Western blotting. The T2DM rat model was reproduced and then treated with OPSR for 4 weeks. Body weight (BW, triglyeride (TG, fasting blood glucose (FBG and fasting insulin (FINs of the rats were measured respectively. Results  OPSR in dosage of 0.5-50mg/L promoted glucose consumption of adipocytes in a dose-dependent manner, the glucose consumption ratios were 32.27%, 75.14% and 90.47% respectively. OPG of 50mg/L showed very weak activity with glucose consumption ratio of only 8.49%. OPSR could significantly promote the protein expression of leptin and adiponectin, and showed an inhibitory effect on the protein expression of resistin (P<0.05. After treatment with OPSR for 4 weeks, the BW of rats increased obviously, while TG, FBG and HOMA-IR decreased significantly (P<0.05 or P<0.01. Conclusions  OPSR may promote glucose transport and utilization of adipocytes, decrease the level of FBG and TG, and improve the condition of IR in T2DM rats. The mechanism of blood glucose lowering effect may be attributed to secretion of adipokines, such as leptin, adiponectin and resistin by IR adipocytes.

    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.

    A closed-loop glycemic control system using an artificial pancreas has been applied with many clinical benefits in Japan since 1987. To update this system incorporating user-friendly features, we developed a novel artificial pancreas (STG-55). The purpose of this study was to evaluate STG-55 for device usability, performance of blood glucose measurement, glycemic control characteristics in vivo in animal experiments, and evaluate its clinical feasibility. There are several features for usability improvement based on the design concepts, such as compactness, display monitor, batteries, guidance function, and reduction of the preparation time. All animal study data were compared with a clinically available artificial pancreas system in Japan (control device: STG-22). We examined correlations of both blood glucose levels between two groups (STG-55 vs. control) using Clarke's error grid analysis, and also compared mean glucose infusion rate (GIR) during glucose clamp. The results showed strong correlation in blood glucose concentrations (Pearson's product-moment correlation coefficient: 0.97; n = 1636). Clarke's error grid analysis showed that 98.4% of the data fell in Zones A and B, which represent clinically accurate or benign errors, respectively. The difference in mean GIRs was less than 0.2 mg/kg/min, which was considered not significant. Clinical feasibility study demonstrated sufficient glycemic control maintaining target glucose range between 80 and 110 (mg/dL), and between 140 and 160 without any hypoglycemia. In conclusion, STG-55 was a clinically acceptable artificial pancreas with improved interface and usability. A closed-loop glycemic control system with STG-55 would be a useful tool for surgical and critical patients in intensive care units, as well as diabetic patients.

    Full Text Available Background: Early and non-invasive determination of blood glucose level is of great importance. We aimed to present a new technique to accurately infer the blood glucose concentration in peripheral blood flow using non-invasive optical monitoring system.Methods: The data for the research were obtained from 900 individuals. Of them, 750 people had diabetes mellitus (DM. The system was designed using a helium neon laser source of 632.8 nm wavelength with 5mW power, photo detectors and digital storage oscilloscope. The laser beam was directed through a single optical fiber to the index finger and the scattered beams were collected by the photo detectors placed circumferentially to the transmitting fiber. The received signals were filtered using band pass filter and finally sent to a digital storage oscilloscope. These signals were then decomposed into approximation and detail coefficients using modified Haar Wavelet Transform. Back propagation neural and radial basis functions were employed for the prediction of blood glucose concentration.Results: The data of 450 patients were randomly used for training, 225 for testing and the rest for validation. The data showed that outputs from radial basis function were nearer to the clinical value. Significant variations could be seen from signals obtained from patients with DM and those without DM.Conclusion: The proposed non-invasive optical glucose monitoring system is able to predict the glucose concentration by proving that there is a definite variation in hematological distribution between patients with DM and those without DM.

    Full Text Available The effect of severe food restriction since birth on regulation of fasting glycemia in male Wistar rats was investigated. The control group (CG had free supply of chow, while the restriction group (RG received 50% of the amount ingested by the CG. The experiments were done in adult (60 days overnight fasted rats in which glycemia, liver free glucose levels and hepatic glycogen concentration were measured. In part of the experiments in situ liver perfusion was done. The results showed that livers from the RG had higher glycogenolysis rates but lower gluconeogenesis rates from L-alanine (10 mM. Since RG showed maintained glycemia during fasting, it could be concluded that livers from RG produced glucose preferentially from glycogenolysis in detriment of gluconeogenesis. These findings demonstrated that in spite of severe caloric restriction, the metabolic adaptations of the liver did exist to assure the maintenance of blood glucose for brain supply during fasting.

    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.

    Cognitive functioning was assessed in diabetic patients during hypoglycemia (60 mg/dl), euglycemia/control (110 mg/dl), and hyperglycemia (300 mg/dl). Blood glucose levels were set and maintained to within 4% of targeted levels by an artificial insulin/glucose infusion system (Biostator). Attention and fine motor skills, assessed by visual reaction time, was slowed at altered glucose levels. Performance was less impaired during hyperglycemia than hypoglycemia when a longer interstimulus interval was used, although it was still slower than normal. The time required to solve simple addition problems was increased during hypoglycemia, although reading comprehension was not affected. The possibility that some automatic brain skills are disrupted at altered glucose concentrations is discussed, while associative or inferential skills may be less affected.

    2016-01-01

    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...

    Recently, zebrafish have been used to examine hyperglycemia-induced complications (retinopathy and neuropathy), as would occur in individuals with diabetes. Current models to induce hyperglycemia in zebrafish include glucose immersion and streptozotocin injections. Both are effective, although neither is reported to elevate blood sugar values for more than 1 month. In this article, we report differences in hyperglycemia induction and maintenance in young (4-11 months) versus old (1-3 years) zebrafish adults. In particular, older fish immersed in an alternating constant external glucose solution (2%) for 2 months displayed elevated blood glucose levels for the entire experimental duration. In contrast, younger adults displayed only transient hyperglycemia, suggesting the fish were acclimating to the glucose exposure protocol. However, modifying the immersion protocol to include a stepwise increasing glucose concentration (from 1% → 2%→3%) resulted in maintained hyperglycemia in younger zebrafish adults for up to 2 months. Glucose-exposed younger fish collected after 8 weeks of exposure also displayed a significant decrease in wet weight. Taken together, these data suggest different susceptibilities to hyperglycemia in older and younger fish and that stepwise increasing glucose concentrations of 1% are required for maintenance of hyperglycemia in younger adults, with higher concentrations of glucose resulting in greater increases in blood sugar values.

    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.

    Objective To observe the changes of plasma glucose level (PGL) in human volunteers after acupuncture. Methods Seventy-seven human volunteers were taken up from the acupuncture clinic. All of pletion of acupuncture. All cases were at four hours abstinence from food before doing acupuncture. Results Plasma glucose level varied 5 mg% or more in 62 cases (80.51%) and only those were considered for computation. PGL increased in cases who had generally plasma glucose level below 90 mg% before acupuncture;and PGL decreased in cases who had plasma glucose 90 mg% or above. In 10 control cases there was no variation of the considerable level of 5 mg% in any case. Conclusion Bi-directional variation of PGL after acupuncture indicates that acupuncture can be used to maintain optimum PGL through endogenous mechanism,suggesting that it is applicable in controlling hyperglycemia in diabetes mellitus patients.

    Background Previous studies have demonstrated that serum uric acid (UA) is an independent predictor of incident type 2 diabetes mellitus (T2DM) in general populations. This study aimed to investigate specific characteristics of UA and its relationship between UA and blood glucose and other risk factors in the Chinese population.Methods A total of 946 subjects were included in this study. UA, glucose, insulin, fractional excretion of UA (FEua),creatinine clearance rate (Ccr), hemoglobin A1c (HbA1c), fructosamine (FA), blood pressure and lipids were studied and also reexamined after the patients underwent two weeks of combined therapeutics.Results UA levels were the highest in subjects with impaired glucose regulation (IGR), followed by subjects with normoglycemia (NGT) and finally by subjects with T2DM. The level of the 2-hour postprandial insulin and the area under the curve for insulin (AUCins) showed a similar tendency. The UA levels initially increased with increasing fasting blood glucose (FBG) and postprandial blood glucose (PPBG) levels, up to 7 mmol/L and 10 mmol/L, respectively, and thereafter decreased at higher FBG and PPBG levels. Compared with subjects in the lower serum UA quartile, subjects in the upper quartile of serum UA levels had higher weights, triglyceride levels, and creatinine levels as well as lower Ccr and FEua levels. Compared with women's group, UA levels were higher, and FEua levels were lower in men's group. Sex,body mass index (BMI), mean arterial blood pressure (MAP), serum triglycerides (TG), FA and Ccr were independent correlation factors of UA. UA decreased and FEua increased after the patients underwent a combined treatment.Conclusions UA increased initially and then decreased as glucose levels increased from NGT to IGR and T2DM.Compared with NGT and T2DM, IGR subjects had higher SUA levels, which related to its high levels of insulin. Under T2DM, male gender, BMI, MAP, Ccr, TG and FA are independent correlation factors of UA

    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.

    Garlic is a common spicy flavouring agent also used for certain therapeutic purposes. Garlic's effects on blood glucose have been the subject of many clinical and animal studies, however, studies reporting hypoglycemic effects of garlic in humans are conflicting. A comprehensive literature search was conducted to identify relevant trials of garlic or garlic extracts on markers of glycemic control [fasting blood glucose (FBG), postprandial glucose (PPG), glycosylated haemoglobin (HbA1c)]. A meta-analysis of the effect of garlic intake on human was done to assess garlic's effectiveness in lowering glucose levels. Two reviewers extracted data from each of the identified studies. Seven eligible randomized controlled trials with 513 subjects were identified. Pooled analyses showed that garlic intake results in a statistically significant lowering in FBG [SMD=-1.67; 95% CI (-2.80, -0.55), p=0.004]. Our pooled analyses did not include PPG control and HbA1c outcomes. Because only 1 study included in the meta-analysis reported PPG variables and only 2 studies reported HbA1c variables. In conclusion, the current meta-analysis showed that the administration of garlic resulted in a significant reduction in FBG concentrations. More trials are needed to investigate the effectiveness of garlic on HbA1c and PPG.

    Patients with diabetes display a progressive decay in the physiological counter-regulatory response to hypoglycemia, resulting in hypoglycemia unawareness. The mechanism through which the brain adapts to hypoglycemia may involve brain glycogen. We tested the hypothesis that brain glycogen supercompensation following hypoglycemia depends on blood glucose levels during recovery. Conscious rats were submitted to hypoglycemia of 2 mmol/L for 90 min and allowed to recover at different glycemia, controlled by means of i.v. glucose infusion. Brain glycogen concentration was elevated above control levels after 24 h of recovery in the cortex, hippocampus and striatum. This glycogen supercompensation was independent of blood glucose levels in the post-hypoglycemia period. In the absence of a preceding hypoglycemia insult, brain glycogen concentrations were unaltered after 24 h under hyperglycemia. In the hypothalamus, which controls peripheral glucose homeostasis, glycogen levels were unaltered. Overall, we conclude that post-hypoglycemia glycogen supercompensation occurs in several brain areas and its magnitude is independent of plasma glucose levels. By supporting brain metabolism during recurrent hypoglycemia periods, glycogen may have a role in the development of hypoglycemia unawareness.

    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.

    Full Text Available Background: Diabetes is an important disease. This disease is a metabolic disorder characterized by hyperglycemia resulting from perturbation in insulin secretion, insulin action or both. Honey bee venom contains a wide range of polypeptide agents. The principle components of bee venom are mellitin and phospholipase A2. These components increase insulin secretion from the β-cells of pancreas. This study was conducted to show the hypoglycemic effect of honey bee venom on alloxan induced diabetic male rats.Methods: Eighteen adult male rats weighting 200±20 g were placed into 3 randomly groups: control, alloxan monohy­drate-induced diabetic rat and treated group that received honey bee venom daily before their nutrition for four months. Forty eight hours after the last injection, blood was collected from their heart, serum was dissented and blood glucose, insulin, triglyceride and total cholesterol were determined.Results: Glucose serum, triglyceride and total cholesterol level in treated group in comparison with diabetic group was significantly decreased (P< 0.01. On the other hand, using bee venom causes increase in insulin serum in com­parison with diabetic group (P< 0.05.Conclusion: Honeybee venom (apitoxin can be used as therapeutic option to lower blood glucose and lipids in dia­betic rats.

    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.

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

    Despite the significant value of the southeastern United States' red drum (Sciaenops ocellatus) fishery, there is a lack of clinical blood chemistry data. This was the first study to assess plasma glucose values as an indicator of stress response to evaluate variation and the effect of reproductive activity for wild adult red drum in Florida. Red drum (n=126) were collected from NASA's Kennedy Space Center waters during three reproductive periods in 2011. Samples were obtained from the branchial vessels of the gill arch. Plasma glucose levels were significantly different among reproductive periods, with the highest mean values recorded during the spawning period, September- October (38.23 mg / dL +/- 10.0). The glucose range was 17 - 69 mg / dL. Glucose values were lower during all three periods than previous values recorded for cultured or captive red drum studies. This may indicate that fish from this population were under less stress than other populations previously sampled.

    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.

    This study investigated both morphologically and biochemically whether parsley (Petroselinum crispum), which is used as a folk remedy to decrease blood glucose, has any antidiabetic effect on pancreatic B cells of rats. Parsley extract was given to male diabetic rats. In the diabetic group given parsley extract, it was detected that the number of secretory granules and cells in islets and other morphologic changes were not different from the control diabetic group, while the blood glucose levels in the diabetic group given the plant extract were reduced in comparison to the diabetic group. In addition, a decrease was observed in the weight of the control diabetic group and the diabetic group given the plant extract. It is suggested that the plant therapy can provide blood glucose homeostasis and cannot regenerate B cells of the endocrine pancreas.

    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.

    Obesity is a condition in which the body fat stores are increased to an extent which impairs health and leads to serious health consequences. The amount of body fat is difficult to measure directly, and is usually determined from an indirect measure - the body mass index (BMI). Increased BMI in obese persons is directly associated with an increase in metabolic disease, such as type 2 diabetes mellitus. This Analytical cross sectional study was undertaken to assess the relation between obesity and glycemic control of body by measuring fasting serum glucose and glycosylated hemoglobin. This study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh from 1st July 2011 to 30th June 2012 on 120 equally divided male and female persons within the age range of 25 to 55 years. Age more than 55 years and less than 25 years and diagnosed case of Hypothyroidism, Cushing's syndrome, polycystic ovary, Antipsychotic drug user and regular steroid users were excluded. Non probability purposive type of sampling technique was used for selecting the study subjects. Measurement of body mass index was done as per procedure. Fasting serum glucose was estimated by glucose oxidase method and Glycosylated hemoglobin by Boronate Affinity method. Statistical analysis was done by SPSS (version 17.0). Data were expressed as Mean±SE and statistical significance of difference among the groups were calculated by unpaired student's 't' test and Pearson's correlation coefficient tests were done as applicable. The Mean±SE of fasting serum glucose was significant at 1% level (P value glycosylated hemoglobin level between control and study groups. But there was positive correlation within each group. Fasting serum glucose also showed a bit stronger positive correlation with BMI. Both obese male and female persons showed higher levels of fasting serum glucose and glycosylated hemoglobin. The observed positive correlation between BMI with fasting serum glucose and

    We investigated the effect of curcumin on insulin resistance and glucose homeostasis in male C57BL/KsJ-db/db mice and their age-matched lean non-diabetic db/+ mice. Both db/+ and db/db mice were fed with or without curcumin (0.02%, wt/wt) for 6 wks. Curcumin significantly lowered blood glucose and HbA 1c levels, and it suppressed body weight loss in db/db mice. Curcumin improved homeostasis model assessment of insulin resistance and glucose tolerance, and elevated the plasma insulin level in db/db mice. Hepatic glucokinase activity was significantly higher in the curcumin-supplemented db/db group than in the db/db group, whereas glucose-6-phosphatase and phosphoenolpyruvate carboxykinase activities were significantly lower. In db/db mice, curcumin significantly lowered the hepatic activities of fatty acid synthase, beta-oxidation, 3-hydroxy-3-methylglutaryl coenzyme reductase, and acyl-CoA: cholesterol acyltransferase. Curcumin significantly lowered plasma free fatty acid, cholesterol, and triglyceride concentrations and increased the hepatic glycogen and skeletal muscle lipoprotein lipase in db/db mice. Curcumin normalized erythrocyte and hepatic antioxidant enzyme activities (superoxide dismutase, catalase, gluthathione peroxidase) in db/db mice that resulted in a significant reduction in lipid peroxidation. However, curcumin showed no effect on the blood glucose, plasma insulin, and glucose regulating enzyme activities in db/+ mice. These results suggest that curcumin seemed to be a potential glucose-lowering agent and antioxidant in type 2 diabetic db/db mice, but had no affect in non-diabetic db/+ mice.

    Strict glycemic control needs to be maintained in critically ill surgical patients to reduce the mortality and morbidity due to hyperglycemia and associated infection. However, conventional intensive insulin therapy (IIT), which consists of intermittent blood glucose measurement and manually controlled infusions of insulin, tends to induce hypoglycemia and glucose variability. Many randomized clinical trials have been conducted to improve the efficacy of IIT, although some of these were stopped owing to frequent hypoglycemia. In pursuing safe and strict glycemic control for critically ill surgical patients, we found that a closed-loop glycemic control system was able to maintain appropriate blood glucose levels without hypoglycemia in more than 400 clinical cases. Considering the need for the perioperative and intensive care environment, a well-established artificial pancreas was modified into a new closed-loop glycemic control system, called the progressive artificial pancreas. The new device is slim in shape and shows clinical compatibility with the conventional artificial pancreas. We herein review this new closed-loop glycemic control system and the expectations for its future application in critically ill surgical patients.

    The energy supplied to the brain by metabolic substrate is largely utilized for maintaining synaptic transmission. In this regulation cerebral blood flow and glucose consumption is tightly coupled as well in the resting condition as during activation. Quantification of cerebral blood flow...... not used for aerobic metabolism. Although some of the excess glucose uptake can be explained by lactate production, this phenomenon can still not account for the excess glucose uptake. Thus, more complex metabolic patterns in the brain might be reflected in the excess glucose uptake during activation...

    Age-associated cognitive impairment is a major health and social issue because of increasing aged population. Cognitive decline is not homogeneous in humans and the determinants leading to differences between subjects are not fully understood. In middle-aged healthy humans, fasting blood glucose levels in the upper normal range are associated with memory impairment and cerebral atrophy. Due to a close evolutional similarity to Man, non-human primates may be useful to investigate the relationships between glucose homeostasis, cognitive deficits and structural brain alterations. In the grey mouse lemur, Microcebus murinus, spatial memory deficits have been associated with age and cerebral atrophy but the origin of these alterations have not been clearly identified. Herein, we showed that, on 28 female grey mouse lemurs (age range 2.4-6.1 years-old), age correlated with impaired fasting blood glucose (rs=0.37) but not with impaired glucose tolerance or insulin resistance. In middle-aged animals (4.1-6.1 years-old), fasting blood glucose was inversely and closely linked with spatial memory performance (rs=0.56) and hippocampus (rs=−0.62) or septum (rs=−0.55) volumes. These findings corroborate observations in humans and further support the grey mouse lemur as a natural model to unravel mechanisms which link impaired glucose homeostasis, brain atrophy and cognitive processes.

    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.

    Locally administered corticosteroids are a common therapy in many hand and wrist disorders. Corticosteroids pose a theoretical risk to patients with diabetes mellitus by potentially raising blood glucose to hyperglycemic levels. Although oral corticosteroids are known to have an effect on blood glucose control, limited data exist on extra-articular administration. The purpose of this study was to examine the systemic impact of extra-articularly administered corticosteroids in the hand and wrist on serum glucose concentration in patients with diabetes mellitus.Twenty-three patients with diabetes mellitus received a 1-mL triamcinolone acetonide injection for de Quervain's tenosynovitis, trigger finger, flexor carpi ulnaris tendonitis, or carpal tunnel syndrome. Patients recorded their daily morning blood glucose levels for 1 week before injection and for 4 weeks after injection. Average blood glucose levels increased slightly from baseline after injection, reaching statistical significance 1, 5, and 6 days after injection, but were not clinically significant (average increase, 14.2, 9.7, and 32.7 mg/dL, respectively). Isolated increases more than 2 times the standard deviation of preinjection values occurred at least once in the majority of patients. The frequency of hyperglycemic episodes increased after injection, but the proportions of patients with at least 1 hyperglycemic episode before and after injection were not significantly different.These results suggest that local corticosteroid injections are a clinically safe treatment option for inflammatory processes of the hand and wrist in patients with diabetes mellitus. On average, patients experienced slight increases in blood glucose after receiving an injection. Most experienced isolated increases substantially beyond baseline and isolated hyperglycemic effects, but these did not pose an apparent clinical risk.

    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

    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.

    Impaired regulation of blood glucose levels in diabetes mellitus (DM) patients and the associated elevation of blood glucose levels are known to increase the risk of diabetic cardiomyopathy (DC). In the present study, a probiotic bacterium, Lactobacillus reuteri GMN-32, was evaluated for its potential to reduce blood glucose levels and to provide protection against DC risks in streptozotocin (STZ)-induced DM rats. The blood glucose levels of the STZ-induced DM rats when treated with L. reuteri GMN-32 decreased from 4480 to 3620 mg/l (with 10⁷ colony-forming units (cfu)/d) and 3040 mg/l (with 10⁹ cfu/d). Probiotic treatment also reduced the changes in the heart caused by the effects of DM. Furthermore, the Fas/Fas-associated protein with death domain pathway-induced caspase 8-mediated apoptosis that was observed in the cardiomyocytes of the STZ-induced DM rats was also found to be controlled in the probiotic-treated rats. The results highlight that L. reuteri GMN-32 treatment reduces blood glucose levels, inhibits caspase 8-mediated apoptosis and promotes cardiac function in DM rats as observed from their ejection fraction and fractional shortening values. In conclusion, the administration of L. reuteri GMN-32 probiotics can regulate blood glucose levels, protect cardiomyocytes and prevent DC in DM rats.

    Full Text Available Recognition and control of depression symptoms are important to increase patient compliance with treatment and to improve the quality of life of diabetic patients. Clinical studies indicate that selective serotonin reuptake inhibitors (SSRI are better antidepressants for diabetic patients than other drugs. However, preclinical trials have demonstrated that not all SSRI reduce plasma glucose levels. In fact, fluoxetine increases and sertraline decreases glycemia in diabetic and non-diabetic rats. In the present study we evaluated plasma insulin levels during fasting and after glucose overload after treatment with sertraline. Adult male Wistar rats were fasted and treated with saline or 30 mg/kg sertraline and submitted or not to glucose overload (N = 10. Blood was collected and plasma insulin was measured. The mean insulin levels were: fasting group: 25.9 ± 3.86, sertraline + fasting group: 31.10 ± 2.48, overload group: 34.1 ± 3.40, and overload + sertraline group: 43.73 ± 5.14 µU/ml. Insulinemia was significantly increased in the overload + sertraline group. There were no differences between the other groups. No difference in glucose/insulin ratios could be detected between groups. The overload + sertraline group was the only one in which a significant number of individuals exceeded the upper confidence limit of insulin levels. This study demonstrates that sertraline increases glucose-stimulated insulin secretion without any change in peripheral insulin sensitivity.

    Full Text Available Abstract Background Evidence-based patient information (EBPI has been recognised as important tool for informed choice in particular in the matter of preventive options. An objective, on the best scientific evidence-based consumer information about subthreshold elevated blood glucose levels (impaired fasting glucose and impaired glucose tolerance and primary prevention of diabetes, is not available yet. Thus we developed a web-based EBPI and aim to evaluate its effects on informed decision making in people 50 years or older. Methods/Design We conduct a web-based randomised-controlled trial to evaluate the effect of information about elevated blood glucose levels and diabetes primary prevention on five specific outcomes: (i knowledge of elevated blood glucose level-related issues (primary outcome; (ii attitudes to a metabolic testing; (iii intention to undergo a metabolic testing; (iv decision conflict; (v satisfaction with the information. The intervention group receives a specially developed EBPI about subthreshold elevated blood glucose levels and diabetes primary prevention, the control group information about this topic, available in the internet. The study population consists of people between 50 and 69 years of age without known diabetes. Participants will be recruited via the internet page of the cooperating health insurance company, Techniker Krankenkasse (TK, and the internet page of the German Diabetes Centre. Outcomes will be measured through online questionnaires. We expect better informed participants in the intervention group. Discussion The design of this study may be a prototype for other web-based prevention information and their evaluation. Trial registration Current Controlled Trial: ISRCTN22060616.

    Both diabetes and periodontal disease are prevalent in China. Poor oral hygiene practice is the major cause of periodontal disease. An association between oral hygiene practice and blood glucose level was reported in individuals with diabetes, but not in the general population. We examined the association in a population-based random survey recruiting 2,105 adults without previously diagnosed diabetes in Chongqing city, China. Plasma glucose and hemoglobin A1c (HbA1c) were measured, and a 2-hour oral glucose tolerance test was conducted for each respondent. Self-reported toothbrushing frequency was used as a proxy for oral hygiene practice. In a linear model controlling for potential confounders (demographic characteristics, socio-economic status, lifestyle risk factors, BMI, dental visit frequency, etc.), urban residents who barely brushed their teeth had an increase of 0.50 (95% CI: 0.10-0.90) mmol/L in fasting plasma glucose, and an increase of 0.26% (0.04-0.47%) in HbA1c, relative to those brushing ≥twice daily; for rural residents, the effects were 0.26 (0.05-0.48) mmol/L in fasting plasma glucose and 0.20% (0.09-0.31%) in HbA1c. Individuals with better oral practice tended to have lower level of blood glucose and HbA1c. Establishing good oral health behavioral habits may be conducive to diabetes prevention and control in the general population.

    Earlier observations on possible co-variation between skin EIS and blood glucose prompted us to map and include other factors at play in the predictive model. Skin pH would be one such factor. A cohort of 20 diabetics was investigated, taking around 30 measurements spread over each of two different days 2-21 days apart. Each measurement comprises skin EIT in the frequency range 1kHz to 2.5MHz, skin pH, and immediately evaluated blood samples. There is a co-variation for some, but not all, test persons. The relationship gets stronger on the group level by adding pH-information, but is still poor or non-existent for some test persons. Non-invasive EIS measurements on skin is influenced by skin hydration, blood glucose, skin pH, body location, season, environmental factors, and variables not yet understood. Since impedance related parameters are used to estimate skin hydration, users of such devices should be aware that skin pH may influence as much as the water content of the stratum corneum.

    Blood chemical analysis for the diagnosis of diseases in forensic cases should be conducted in the same way as for clinical cases. However, it is sometimes difficult to obtain serum samples in forensic cases because of postmortem changes such as hemolysis and putrefaction. This study aimed to evaluate renal function in postmortem cases by blood creatinine analysis. The blood creatinine level was measured by high performance liquid chromatography (HPLC) using whole blood samples taken from 77 postmortem cases, and the relationships between blood creatinine level, postmortem interval, and cause of death were examined. The median blood creatinine level was found to be 1.15 mg/dL, with no significant differences between blood samples taken from different parts of the body. The blood creatinine level was stable for 3 days after death and gradually increased after that period, in line with a previous study using enzymatic analysis that found the serum creatinine level was stable in the early postmortem period. The blood creatinine level was high in the cases of blunt injury, intoxication, and in deaths caused by fire. This was considered to reflect acute renal dysfunction. However, the postmortem blood creatinine level remained higher than the clinical normal value despite omitting cases with renal dysfunction from the analysis. Therefore, we next investigated the change in postmortem creatinine levels in mice and found that the blood creatinine level increased with the emergence of rigor mortis. Our findings indicate that HPLC is useful in the postmortem evaluation of renal function even in the cases where serum cannot be obtained. However, the presence of rigor mortis should be considered in the evaluation of blood creatinine values.

    The concentration of glucose in the extracellular fluid (ECF) of the hippocampus decreases substantially during memory testing on a hippocampus-dependent memory task. Administration of exogenous glucose, which enhances task performance, prevents this decrease, suggesting a relationship between hippocampal glucose availability and memory performance. In the present experiment, spontaneous alternation performance and task-related changes in hippocampal ECF glucose were assessed in rats after intraseptal administration of morphine, which impairs memory on a spontaneous alternation task, and after co-administration of intraseptal glucose, which attenuates that impairment. Consistent with previous findings, spontaneous alternation testing resulted in a decrease in hippocampal ECF glucose levels in control rats. However, rats that received intraseptal morphine prior to testing showed memory impairments and an absence of the task-related decrease in hippocampal ECF glucose levels. Intraseptal co-administration of glucose with morphine attenuated the memory impairment, and ECF glucose levels in the hippocampus decreased in a manner comparable to that seen in control rats. These data suggest that fluctuations in hippocampal ECF glucose levels may be a marker of mnemonic processing and support the view that decreases in extracellular glucose during memory testing reflect increased glucose demand during memory processing.

    This study was designed to investigate the effects of physical conditioning on the expression of the insulin sensitive glucose transporter-4 protein (GLUT4) on mononuclear cells and HOMA-IR levels in dogs and compared to results reported in human skeletal muscle and the skeletal muscle of rodent models. Blood was sampled from conditioned dogs (n = 8) and sedentary dogs (n = 8). The conditioned dogs were exercised four months prior the experiment and were following a uniform training protocol, whereas the sedentary dogs were not. GLUT4 expression in mononuclear cells and plasma insulin levels were measured using commercially available enzyme-linked immunosorbent assay (ELISA). Blood glucose levels were determined using blood plasma. HOMA-IR was calculated using plasma insulin and blood glucose levels using the linear approximation formula. Our results indicate that the state of conditioning had a significant effect on the GLUT4 expression at the surface of mononuclear cells. HOMA-IR was also affected by conditioning in dogs. GLUT4 levels in mononuclear cells of sled dogs were inversely correlated with the homeostasis model assessment of insulin sensitivity. This study demonstrates that conditioning increases GLUT4 levels in mononuclear cells of sled dogs as it has been previously reported in skeletal muscle. Our results support the potential of white blood cells as a proxy tissue for studying insulin signaling and may lead to development of a minimally invasive and direct marker of insulin resistance. This may be the first report of GLUT4 in mononuclear cells in response to exercise and measured with ELISA.

    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.

    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.

    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.

    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.

    Position-based reference measurement method is taken as one of the most promising method in non-invasive measurement of blood glucose based on spectroscopic methodology. Selecting an appropriate source-detector separation as the reference position is important for deducting the influence of background change and reducing the loss of useful signals. Our group proposed a special source-detector separation named floating-reference position where the signal contains only background change, that is to say, the signal at this source-detector separation is uncorrelated with glucose concentration. The existence of floating-reference position has been verified in a three layer skin by Monte Carlo simulation and in the in vitro experiment. But it is difficult to verify the existence of floating-reference position on the human body because the interference is more complex during in vivo experiment. Aiming at this situation, this paper studies the determination of the best reference position on human body by collecting signals at several source-detector separations on the palm and measuring the true blood glucose levels during oral glucose tolerance test (OGTT) experiments of 3 volunteers. Partial least square (PLS) calibration model is established between the signals at every source-detector separation and its corresponding blood glucose levels. The results shows that the correlation coefficient (R) between 1.32 mm to 1.88 mm is lowest and they can be used as reference for background correction. The signal of this special position is important for improving the accuracy of near-infrared non-invasive blood glucose measurement.

    Full Text Available Purpose: The aim of this study was to assess the effects of zinc supplementation on anthropometric measures, improving lipid profile biomarkers, and fasting blood glucose level in obese people. Methods: This randomized, double- blind clinical trial was carried out on 60 obese participants in the 18-45 age range for one month. The participants were randomly divided into the intervention group, who received 30 mg/d zinc gluconate, and the placebo group who received 30mg/d starch. Anthropometric measurements (body mass index (BMI, weight and waist circumference were recorded before and at the end of study. Lipid profile biomarkers and fasting blood glucose were determined using enzymatic procedure. Analysis of Covariance (ANCOVA test was run to compare the post-treatment values of the two groups, and t-test was conducted to compare within group changes. Results: Serum zinc concentration was increased significantly in intervention group (p=0.024. BMI and body weight was significantly decreased (p=0.030 and p=0.020, respectively. Lipid profile biomarkers and fating blood glucose did not change significantly but triglyceride level was significantly decreased (p=0.006 in the intervention group. Conclusion: The obtained results indicate that zinc supplementation improves BMI, body weight, and triglyceride concentration without considerable effects on lipid profile and glucose level. Zinc can be suggested as a suitable supplementation therapy for obese people, but more studies are needed to verify the results.

    Using in vivo microdialysis, we examined glucose levels in the extracellular fluid (ECF) of the hippocampus and in the blood prior to and during pentobarbital (45 mg/kg) or ketamine-xylazine (66 mg/kg, 7 mg/kg) anesthesia. Anesthesia with either pentobarbital or ketamine-xylazine significantly increased hippocampal ECF glucose levels (mean peak increases of +71% and +85%, respectively). In addition, there were substantial increases in blood glucose levels (mean peak increases of +24% and +30%, respectively). The increased levels of hippocampal ECF glucose during anesthesia complement past evidence for decreases in ECF glucose in the hippocampus observed while rats perform a memory task sensitive to hippocampal damage, providing further support for the view that ECF glucose levels in the hippocampus are dynamically coupled to local neural activity.

    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.

    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.

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.

    Changes in plasma glucose, insulin, and growth hormone (HGH) resulting from exposure to 56 d of bedrest were determined in five healthy young male subjects. Changes in the daily levels of these factors for each subject were expressed as the mean of six blood samples per 24-h period. The level of HGH dropped after 10 d of bedrest, then showed a 1.5-fold increase at 20 d and subsequently decreased gradually reaching levels of 2.5 mg/ml/24 h, well below pre-bedrest controls of 4.2 mg/ml/24 h, by the 54th d. In spite of a marked increase in the daily plasma insulin levels during the first 30 d of bedrest, glucose levels remained unchanged. Beyond 30 d of bedrest, insulin began decreasing toward pre-bedrest levels and glucose followed with a similar reduction to below the control levels of 75 mg/100 ml/24 h on day 54. The daily mean changes reflect a change in the amplitude of the diurnal variation. The daily peak in plasma insulin shifted progressively to the late evening during the bedrest period.

  12. Gcg-XTEN: an improved glucagon capable of preventing hypoglycemia without increasing baseline blood glucose.

    Full Text Available OBJECTIVE: While the majority of current diabetes treatments focus on reducing blood glucose levels, hypoglycemia represents a significant risk associated with insulin treatment. Glucagon plays a major regulatory role in controlling hypoglycemia in vivo, but its short half-life and hyperglycemic effects prevent its therapeutic use for non-acute applications. The goal of this study was to identify a modified form of glucagon suitable for prophylactic treatment of hypoglycemia without increasing baseline blood glucose levels. METHODOLOGY/PRINCIPAL FINDINGS: Through application of the XTEN technology, we report the construction of a glucagon fusion protein with an extended exposure profile (Gcg-XTEN. The in vivo half-life of the construct was tuned to support nightly dosing through design and testing in cynomolgus monkeys. Efficacy of the construct was assessed in beagle dogs using an insulin challenge to induce hypoglycemia. Dose ranging of Gcg-XTEN in fasted beagle dogs demonstrated that the compound was biologically active with a pharmacodynamic profile consistent with the designed half-life. Prophylactic administration of 0.6 nmol/kg Gcg-XTEN to dogs conferred resistance to a hypoglycemic challenge at 6 hours post-dose without affecting baseline blood glucose levels. Consistent with the designed pharmacokinetic profile, hypoglycemia resistance was not observed at 12 hours post-dose. Importantly, the solubility and stability of the glucagon peptide were also significantly improved by fusion to XTEN. CONCLUSIONS/SIGNIFICANCE: The data show that Gcg-XTEN is effective in preventing hypoglycemia without the associated hyperglycemia expected for unmodified glucagon. While the plasma clearance of this Gcg-XTEN has been optimized for overnight dosing, specifically for the treatment of nocturnal hypoglycemia, constructs with significantly longer exposure profiles are feasible. Such constructs may have multiple applications such as allowing for more

    Background: It is reasonable to think that some biochemical characteristics of follicular fluid (FF) surrounding the oocyte may play a critical role in determining the quality of oocyte and the subsequent potential needed to achieve fertilization and embryo development. Objective: This study was carried out to evaluate the levels of FF homocysteine (Hcy) in IVF candidate polycystic ovary syndrome (PCOS) women and any relationships with FF glucose and estradiol (E2) levels. Materials and Methods: In this case control study which was performed in Dr. Tizro Day Care and IVF Center 70 infertile patients were enrolled in two groups: comprising 35 PCOS and 35 non PCOS women. Long protocol was performed for all patients. FF Hcy, glucose and E2 levels were analyzed at the time of oocyte retrieval. Results: It was observed that FF Hcy level was significantly higher in PCOS patients compared with non PCOSs (p<0.01). Observations demonstrated that in PCOS group, the Hcy level increased independent to E2, glucose levels, BMI and age, while the PCOS group showed significantly higher BMI compared with non-PCOS group (p=0.03). However, no significant differences were revealed between groups for FF glucose and E2 levels. Conclusion: Present data showed that although FF glucose and E2 levels were constant in PCOS and non PCOS patients, but the FF Hcy levels in PCOS were significantly increased (p=0.01). PMID:27679823

  14. Blood glucose control in patients with severe sepsis and septic shock

    The main pathophysiological feature of sepsis is the uncontrollable activation of both pro- and anti-inflammatory responses arising from the overwhelming production of mediators such as pro- and anti-inflammatory cytokines. Such an uncontrollable inflammatory response would cause many kinds of metabolic derangements.One such metabolic derangement is hyperglycemia.Accordingly, control of hyperglycemia in sepsis is considered to be a very effective therapeutic approach. However, despite the initial enthusiasm, recent studies reported that tight glycemic control with intensive insulin therapy failed to show a beneficial effect on mortality of patients with severe sepsis and septic shock. One of the main reasons for this disappointing result is the incidence of harmful hypoglycemia during intensive insulin therapy. Therefore, avoidance of hypoglycemia during intensive insulin therapy may be a key issue in effective tight glycemic control.It is generally accepted that glycemic control aimed at a blood glucose level of 80-100 mg/dL, as initially proposed by van den Berghe, seems to be too tight and that such a level of tight glycemic control puts septic patients at increased risk of hypoglycemia. Therefore,now many researchers suggest less strict glycemic control with a target blood glucose level of 140-180 mg/dL.Also specific targeting of glycemic control in diabetic patients should be considered. Since there is a significant correlation between success rate of glycemic control and the degree of hypercytokinemia in septic patients,some countermeasures to hypercytokinemia may be an important aspect of successful glycemic control. Thus,in future, use of an artificial pancreas to avoid hypoglycemia during insulin therapy, special consideration of septic diabetic patients, and control of hypercytokinemia should be considered for more effective glycemic control in patients with severe sepsis and septic shock.

    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

    Full Text Available Strategies to prevent diabetic microvascular angiopathy focus on the vascular endothelium. Because red blood cells (RBCs are less deformable in diabetes, we explored an original concept linking decreased RBC deformability to RBC ascorbate and hyperglycemia. We characterized ascorbate concentrations from human and mouse RBCs and plasma, and showed an inverse relationship between RBC ascorbate concentrations and deformability, measured by osmotic fragility. RBCs from ascorbate deficient mice were osmotically sensitive, appeared as spherocytes, and had decreased β-spectrin. These aberrancies reversed with ascorbate repletion in vivo. Under physiologic conditions, only ascorbate's oxidation product dehydroascorbic acid (DHA, a substrate for facilitated glucose transporters, was transported into mouse and human RBCs, with immediate intracellular reduction to ascorbate. In vitro, glucose inhibited entry of physiologic concentrations of dehydroascorbic acid into mouse and human RBCs. In vivo, plasma glucose concentrations in normal and diabetic mice and humans were inversely related to respective RBC ascorbate concentrations, as was osmotic fragility. Human RBC β-spectrin declined as diabetes worsened. Taken together, hyperglycemia in diabetes produced lower RBC ascorbate with increased RBC rigidity, a candidate to drive microvascular angiopathy. Because glucose transporter expression, DHA transport, and its inhibition by glucose differed for mouse versus human RBCs, human experimentation is indicated.

    Cerebral blood flow, cerebral oxygen metabolic rate and cerebral glucose metabolic rate were measured with positron emission tomography (PET) in four patients with progressive supranuclear palsy (PSP). Decreased blood flow and hypometabolism of oxygen and glucose were found in both subcortical and cortical regions, particularly in the striatum including the head of the caudate nucleus and the frontal cortex. The coupling between blood flow and metabolism was preserved even in the regions which showed decreased blood flow and hypometabolism. These findings indicated the hypofunction, as revealed by decreased blood flow and hypometablolism on PET, both in the striatum and the frontal cortex, and which may underlie the pathophysiological mechanism of motor and mental disturbance in PSP.

    Noninvasive monitoring of blood glucose concentration in diabetic patients would significantly reduce complications and mortality associated with this disease. In this paper, we experimentally and theoretically studied specificity of noninvasive blood glucose monitoring with the optical coherence tomography (OCT) technique. OCT images and signals were obtained from skin of Yucatan micropigs and New Zealand rabbits. Obtained results demonstrate that: (1) several body osmolytes may change the refractive index mismatch between the interstitial fluid (ISF) and scattering centres in tissue, however the effect of the glucose is approximately one to two orders of magnitude higher; (2) an increase of the ISF glucose concentration in the physiological range (3-30 mM) may decrease the scattering coefficient by 0.22% mM(-1) due to cell volume change; (3) stability of the OCT signal slope is dependent on tissue heterogeneity and motion artefacts; and (4) moderate skin temperature fluctuations (+/- 1 degree C) do not decrease accuracy and specificity of the OCT-based glucose sensor, however substantial skin heating or cooling (several degrees C) significantly change the OCT signal slope. These results suggest that the OCT technique may provide blood glucose concentration monitoring with sufficient specificity under normal physiological conditions.

    Full Text Available Continuous glucose monitoring (CGM sensors able to monitor blood glucose concentration continuously (i.e. with a reading every 1-5 min for several days (up to 7 consecutive days, entered clinical research. The availability of continuous glucose monitoring (CGM sensors allows development of new strategies for the treatment of diabetes. CGM sensors are of two types, noninvasive (NI-CGM or minimally-invasive (MI-CGM. Irrespective of the type, CGM sensors can become smart by providing them with algorithms able to generate alerts, say, 20-30 min ahead of time, when glucose concentration is predicted to exceed the normal range thresholds (70-180 mg/dL. Such alerts would allow diabetes patients to take precautionary measures to prevent hypo/hyperglycemia. In this paper we review blood glucose prediction algorithms such as first-order autoregressive( AR(1 , Kalman Filtering and Feed Forward Neural Network. All these algorithms have demonstrated that blood glucose can be predicted ahead in time.

    The noninvasive measurement of human blood glucose was achieved with NIR diffusion reflectance spectrum method. The thumb fingertip NIR diffusion reflectance spectra of six different age healthy volunteers were collected using Nexus-870 and its NIR fiber port smart accessory. The test was implemented with changing the blood glucose concentration for the limosis and satiation of every volunteer. The calibration model was set up using PLS method with the smoothing, baseline correction and first derivatives pretreatment spectrum in the 7500-8500 cm(-1) region for single volunteer, the same age combination and that of different age. When the spectrum was obtained, the actual blood glucose value of every spectrun sample was demarcated using ultraviolet spectrophotometer. The correlation between the calibration value and true value for single volunteer is better than that for the combination of volunteers, the correlative coefficients are all over 0.90471, RMSECs are all less than 0.171.

    Full Text Available Abstract Background Over the past several years our research group has taken a systematic, comprehensive approach to determining the effects on body function (hormonal and non-hormonal of varying the amounts and types of proteins, carbohydrates and fats in the diet. We have been particularly interested in the dietary management of type 2 diabetes. Our objective has been to develop a diet for people with type 2 diabetes that does not require weight loss, oral agents, or insulin, but that still controls the blood glucose concentration. Our overall goal is to enable the person with type 2 diabetes to control their blood glucose by adjustment in the composition rather than the amount of food in their diet. Methods This paper is a brief summary and review of our recent diet-related research, and the rationale used in the development of diets that potentially are useful in the treatment of diabetes. Results We determined that, of the carbohydrates present in the diet, absorbed glucose is largely responsible for the food-induced increase in blood glucose concentration. We also determined that dietary protein increases insulin secretion and lowers blood glucose. Fat does not significantly affect blood glucose, but can affect insulin secretion and modify the absorption of carbohydrates. Based on these data, we tested the efficacy of diets with various protein:carbohydrate:fat ratios for 5 weeks on blood glucose control in people with untreated type 2 diabetes. The results were compared to those obtained in the same subjects after 5 weeks on a control diet with a protein:carbohydrate:fat ratio of 15:55:30. A 30:40:30 ratio diet resulted in a moderate but significant decrease in 24-hour integrated glucose area and % total glycohemoglobin (%tGHb. A 30:20:50 ratio diet resulted in a 38% decrease in 24-hour glucose area, a reduction in fasting glucose to near normal and a decrease in %tGHb from 9.8% to 7.6%. The response to a 30:30:40 ratio diet was similar

    Developing noninvasive blood glucose monitoring method is an to immense need to alleviate the pain and suffering of diabetics associated with the frequent pricking of skin for taking blood sample. A hybrid algorithm for multivariate calibration is proposed to improve the prediction performance of classification of diabetes and measurement of blood glucose concentration by near infrared (NIR) spectroscopy noninvasively. The algorithm is based on wavelet prism modified uninformative variable elimination approach (WP-mUVE) combined with least squares support vector machine (LSSVM), named as WP-mUVE-LSSVM. The method is successfully applied to diabetic classification experiment (in vivo) and blood glucose concentration measurement experiment (in vivo) respectively. Human tongue is selected as the measuring site in this study. To evaluate effectiveness of pretreatment method and quality of calibration models, several usually used pretreatment methods and kernel functions of LSSVM are introduced comparing with our method. Higher quality data is obtained by our pretreatment method owing to the elimination of varying background and noise of spectra data simultaneously. Better prediction accuracy and adaptability are obtained by LSSVM model with radial basis kernel function. The results indicate that WP-mUVE-LSSVM holds promise for the classification of diabetes and measurement of blood glucose concentration noninvasively based on human tongue using NIR spectroscopy.

    Background and Aims: The association between hyperglycemia and mortality is believed to be influenced by the presence of diabetes mellitus (DM). In this study, we evaluated the effect of preexisting hyperglycemia on the association between acute blood glucose management and mortality in critically ill patients. The primary objective of the study was the relationship between HbA1c and mortality in critically ill patients. Secondary objectives of the study were relationship between Intensive Care Unit (ICU) admission blood glucose and glucose control during ICU stay with mortality in critically ill patients. Materials and Methods: Five hundred patients admitted to two ICUs were enrolled. Blood sugar and hemoglobin A1c (HbA1c) concentrations on ICU admission were measured. Age, sex, history of DM, comorbidities, Acute Physiology and Chronic Health Evaluation II score, sequential organ failure assessment score, hypoglycemic episodes, drug history, mortality, and development of acute kidney injury and liver failure were noted for all patients. Results: Without considering the history of diabetes, nonsurvivors had significantly higher HbA1c values compared to survivors (7.25 ± 1.87 vs. 6.05 ± 1.22, respectively, P < 0.001). Blood glucose levels in ICU admission showed a significant correlation with risk of death (P < 0.006, confidence interval [CI]: 1.004–1.02, relative risk [RR]: 1.01). Logistic regression analysis revealed that HbA1c increased the risk of death; with each increase in HbA1c level, the risk of death doubled. However, this relationship was not statistically significant (P: 0.161, CI: 0.933–1.58, RR: 1.2). Conclusions: Acute hyperglycemia significantly affects mortality in the critically ill patients; this relation is also influenced by chronic hyperglycemia. PMID:27076705

    1990-11-01

    A relatively simple, new test-strip for blood-glucose monitoring, the Glucoprofil strip with a reaction-zone of film-foil, was evaluated by testing 100 different blood glucose concentrations between 2.1 and 29.7 mmol/l. The results were obtained visually before and after training to read the color changes of the strip according to the scale on the strip-container. Plasma glucose measurements with the Beckman Glucose-Analyzer were used for reference. The results show that the Glucoprofil-strip readings correlated well with the reference method (r = 0.97), thorough training provided. The mean deviation of the strip results was less than 1 mmol/l. Similar results were obtained using another blood glucose strip, the Haemoglukotest 20-800 R. Our study indicates that the performance of the Glucoprofil strip is satisfactory, and hence the strip may be useful for clinical purposes. Consistent with previous reports we could demonstrate that training improved the reading results of the Glucoprofil strip.

    Full Text Available OBJECTIVE: The association between blood glucose and carotid intima-media thickness (CIMT is considered to be established knowledge. We aimed to assess whether associations between different measures of glycaemia and CIMT are actually independent of anthropometric variables and metabolic risk factors. Moreover, we checked published studies for the adjustment for shared risk factors of blood glucose and CIMT. METHODS: Fasting glucose, 2-hour glucose, HbA1c, and CIMT were measured in 31-81-years-old participants of the population-based Cooperative Health Research in the Region of Augsburg (KORA F4 study in Southern Germany (n = 2,663. CIMT was assessed according to the Rotterdam protocol. Linear and logistic regression models with adjustment for age, sex, anthropometric measures, hypertension, and dyslipidaemia were fitted to assess the association between continuous measures of glycaemia, and categories of glucose regulation, respectively, with CIMT. RESULTS: We found a 0.10 mm increase (95%-confidence interval: 0.08-0.12 in CIMT in subjects with compared to subjects without diabetes in crude analysis. This increase was not significant in age-sex adjusted models (p = 0.17. Likewise, neither impaired fasting glucose (p = 0.22 nor impaired glucose tolerance (p = 0.93 were associated with CIMT after adjustment for age, sex, and waist circumference. In multivariable adjusted models, age, sex, hypertension, waist circumference, HDL and LDL cholesterol, but neither fasting glucose nor 2-hour glucose nor HbA1c were associated with elevated CIMT. Literature findings are inconclusive regarding an independent association of glucose levels and CIMT. CONCLUSION: CIMT is highly dependent on traditional cardiovascular risk factors, but no relationships between blood glucose and CIMT were found after adjustment for age, sex, and anthropometric variables.

    Type 2 diabetes can be a problem for captive chimpanzees. Accurate blood glucose (BG) readings are necessary to monitor and treat this disease. Thus, obtaining voluntary samples from primates through positive reinforcement training (PRT) is critical. The current study assessed the voluntary participation of 123 chimpanzees in BG sampling and investigated factors that may contribute to individual success. All subjects participate in regular PRT sessions as part of a comprehensive behavioral management program. Basic steps involved in obtaining BG values include: voluntarily presenting a finger/toe; allowing digit disinfection; holding for the lancet device; and allowing blood collection onto a glucometer test strip for analysis. We recorded the level of participation (none, partial, or complete) when each chimpanzee was first asked to perform the testing procedure. Nearly 30% of subjects allowed the entire procedure in one session, without any prior specific training for the target behavior. Factors that affected this initial successful BG testing included sex, personality (chimpanzees rated higher on the factor "openness" were more likely to participate with BG testing), and past training performance for "present-for-injection" (chimpanzees that presented for their most recent anesthetic injection were more likely to participate). Neither age, rearing history, time since most recent anesthetic event nor social group size significantly affected initial training success. These results have important implications for captive management and training program success, underlining individual differences in training aptitude and the need for developing individual management plans in order to provide optimal care and treatment for diabetic chimpanzees in captivity.

    2016-01-01

    The number of patients with diabetes has reached over 350 million, and still continues to increase. The need for regular blood glucose monitoring sparks the interest in the development of modern detection technologies. One of those methods, which allows for noninvasive measurements, is Raman spectroscopy. The ability of infrared light to penetrate deep into tissues allows for obtaining measurements through the skin without its perforation. This paper presents the limitations and possibilities of non-invasive blood glucose monitoring with Raman spectroscopy. Especially focusing on the possibilities for device miniaturization. Such device incorporates a Raman spectrometer, a fiber-optical probe, and a computing device (microcontroller, smartphone, etc.) which calculates the glucose concentration using specialized algorithms. Simplification of device design, as well as turbidity correction technique and a new proposed method of synchronized detection are described.

    Context: Using the first drop or second drop of blood while measuring blood glucose (BG) values. Objective: The study was planned to compare the BG values from the first and second drops of blood. Research Settings: The study was conducted at the Main Intensive Care Unit, PGIMER, Chandigarh, India. Research Design: This study was a comparative study. Materials and Methods: Ninety patients aged 2–93 years were enrolled in this study. BG values from the first and second drops of blood were taken and compared. Statistical Analysis Used: Agreement between two drops was assessed using Bland–Altman analysis. A bias of <10 mg/dl was considered clinically acceptable. Linear regression of the mean difference (bias) with the BG readings was performed. Results: One thousand four hundred and seven pairs of BG readings were taken from the enrolled patients. BG values had a bias of 3.9 ± 14.9 mg/dl. Nearly 96.7% of BG readings were within the limits of agreement. The absolute difference between first and second drops of blood was calculated; nearly 75.4% of the readings had fallen between 0 and 10 mg/dl, i.e. clinically acceptable range. Conclusion: There is no compete concordance of values of blood glucose between the first and the second drops of blood; any of the drops can be used for measuring BG values as the difference is not statistically significant. However, if hands are visibly clean and to decrease the blood loss in the critically ill patients where the BG values are measured frequently, using the first drop of blood is advised. PMID:27994381

    Nerve cell metabolism in post brain ischemia depends on increased microcirculation perfusion and transport function of microvascular endothelial cells. In the present study, a rat model of middle cerebral artery occlusion was established to investigate the influence of electroacupuncture(EA)on hippocampal CA1 cerebral blood flow and glucose transporter 1(GLUT1)expression in the microvascular endothelial cp.lls. Following EA at Neiguan(PC 6), the cerebral blood flow in the ischemic hippocampal CA1 region was significantly elevated, the number and microvascular integrated absorbance of the GLUTl-positive cells were significantly increased, nerve cell damage was ameliorated, and GLUT1 protein expression in the ischemic hippocampus was significantly increased. Results demonstrate that EA increased the cerebral blood flow of the hippocampal CA1 region and improved the glucose transport function, thereby attenuating neuronal injuries.

    Natal dispersal of sea turtles is an energetically demanding activity that is fuelled primarily by aerobic metabolism. However, during intense exercise reptiles can use anaerobic metabolism to supplement their energy requirements. We assessed anaerobic metabolism in dispersing hatchling loggerhead and flatback turtles by measuring the concentrations of blood lactate during crawling and at different times during the first four hours of their frenzy swim. We also measured concentrations of blood glucose and corticosterone. Blood lactate (12.13 to 2.03 mmol/L, glucose (6.25 to 3.8 mmol/L and corticosterone (8.13 to 2.01 ng/mL concentrations decreased significantly over time in both loggerhead and flatback hatchlings and no significant differences were found between the species. These results indicate that anaerobic metabolism makes a significant contribution to the dispersal phase of hatchling sea turtles during the beach crawl and the first few hours of the frenzy swim.

    Full Text Available Background: People who use home blood glucose monitors may use their mobile phones in the close vicinity of medical devices. This study is aimed at investigating the effect of the signal strength of 900 MHz GSM mobile phones on the accuracy of home blood glucose monitors. Methods: Sixty non-diabetic volunteer individuals aged 21 - 28 years participated in this study. Blood samples were analyzed for glucose level by using a common blood glucose monitoring system. Each blood sample was analyzed twice, within ten minutes in presence and absence of electromagnetic fields generated by a common GSM mobile phone during ringing. Blood samples were divided into 3 groups of 20 samples each. Group 1: exposure to mobile phone radiation with weak signal strength. Group2: exposure to mobile phone radiation with strong signal strength. Group3: exposure to a switched–on mobile phone with no signal strength. Results: The magnitude of the changes in the first, second and third group between glucose levels of two measurements (׀ΔC׀ (were 7.4±3.9 mg/dl, 10.2±4.5 mg/ dl, 8.7±8.4 mg/dl respectively. The difference in the magnitude of the changes between the 1st and the 3rd groups was not statistically significant. Furthermore, the difference in the magnitude of the changes between the 2nd and the 3rd groups was not statistically significant. Conclusion: Findings of this study showed that the signal strength of 900 MHz GSM mobile phones cannot play a significant role in changing the accuracy of home blood glucose monitors.

    Background The probability and risk of operations increase in patients with type 2 diabetes mellitus.For diabetic patients,blood glucose control is a key factor to improving the prognosis of surgery.During perioperative period,insulin therapy is usually advised to be used for surgical patients with type 2 diabetes.However,the insulin regimen which one is better remains controversial.In this study,we estimated the efficacy,safety and advantage of different insulin therapy strategy during perioperative period.Methods A total of 1086 cases of surgical patients with type 2 diabetes mellitus enrolled in the present study.According to the glucose level at admission,all patients were divided into relatively high glucose group (group A,fasting blood glucose (FBG) <13.9 mmol/L) and higher glucose group (group B,FBG >13.9 mmol/L).Patients in group A randomly accepted premixed insulin twice a day,or basal insulin plus oral medications,and were divided into group A1 and A2 respectively.Patients in group B randomly received premixed insulin twice daily,basal insulin plus oral hypoglycemic agents,or basal insulin plus preprandial insulin,and were divided into group B1,B2 and B3 respectively.The data of the preoperative preparation time,the daily doses of insulin used in different periods,postoperative incision healed installments,hypoglycemic events,the total hospitalization time,postoperative complications were all collected and statistically analyzed.Results Compared the main outcome measures in groups treated by premixed insulin therapy,both in preoperative preparation and postoperative period,the daily insulin dosage and the frequency of hypoglycemic events were decreased in groups treated by basal insulin therapy (P <0.05).The preoperative preparation time and the total hospitalization time in groups with basal insulin therapy were shorter than that in groups with premixed insulin therapy (P <0.05).The incision healing rate of stage Ⅰ,Ⅱ and Ⅲ among different

    We investigated whether self-reported racial discrimination was associated with continuous glucose levels and variability in individuals with diabetes, and whether diabetes distress mediated these associations. Seventy-four Black and White women with type 2 diabetes completed the Experience of Discrimination scale, a measure of lifetime racial discrimination, and the Problem Areas in Diabetes, a measure of diabetes distress. Participants wore a continuous glucose monitor for 24 h after 8 h of fasting, a standard meal, and a 4-h run in period. Higher discrimination predicted higher continuous mean glucose and higher standard deviation of glucose. For both mean and standard deviation of glucose, a race × discrimination interaction indicated a stronger relationship between discrimination and glucose for Whites than for Blacks. Diabetes distress mediated the discrimination-mean glucose relationship. Whites who report discrimination may be uniquely sensitive to distress. These preliminary findings suggest that racial discrimination adversely affects glucose control in women with diabetes, and does so indirectly through diabetes distress. Diabetes distress may be an important therapeutic target to reduce the ill effects of racial discrimination in persons with diabetes.

    Full Text Available A potential association between diabetes and Guillain-Barré syndrome (GBS has been indicated by a few case studies. We retrospectively analyzed the clinical features of a large cohort of GBS patients to explore the relationship between the level of fasting plasma glucose (FPG obtained in the acute phase at admission and the severity of GBS.Three hundred and four GBS patients were divided into two groups, one with normal FPG and the other with high FPG levels according to the international standards of FPG.The GBS disability scale score was positively, the Medical Research Council (MRC sum score was negatively correlated to the level of FPG, but not to blood HBA1c or CSF glucose concentrations. A relatively higher FPG level was observed in older and younger GBS patients, and more often in those with cranial nerve involvement, autonomic deficit, dyspnea and ventilator dependence than in patients without these clinical characteristics. Importantly, higher levels of FPG at admission were associated with poorer short-term prognosis measured by the MRC sum score and the GBS disability scale at discharge.Our data demonstrates that FPG in the acute phase of GBS correlates with the severity of GBS and may predict the short-term prognosis of GBS.

    Glucose meters (GMs) are routinely used for self-monitoring of blood glucose by patients and for point-of-care glucose monitoring by health care providers in outpatient and inpatient settings. Although widely assumed to be accurate, numerous reports of inaccuracies with resulting morbidity and mortality have been noted. Insulin dosing errors based on inaccurate GMs are most critical. On October 28, 2011, the Diabetes Technology Society invited 45 diabetes technology clinicians who were attending the 2011 Diabetes Technology Meeting to participate in a closed-door meeting entitled New Criteria for Assessing the Accuracy of Blood Glucose Monitors. This report reflects the opinions of most of the attendees of that meeting. The Food and Drug Administration (FDA), the public, and several medical societies are currently in dialogue to establish a new standard for GM accuracy. This update to the FDA standard is driven by improved meter accuracy, technological advances (pumps, bolus calculators, continuous glucose monitors, and insulin pens), reports of hospital and outpatient deaths, consumer complaints about inaccuracy, and research studies showing that several approved GMs failed to meet FDA or International Organization for Standardization standards in postapproval testing. These circumstances mandate a set of new GM standards that appropriately match the GMs' analytical accuracy to the clinical accuracy required for their intended use, as well as ensuring their ongoing accuracy following approval. The attendees of the New Criteria for Assessing the Accuracy of Blood Glucose Monitors meeting proposed a graduated standard and other methods to improve GM performance, which are discussed in this meeting report.

    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.

    Background The debate over the overall benefits of self-monitoring of blood glucose in type 2 diabetes patients is still continuing.We aimed to assess the difference in glycaemic control and coronary heart disease (CHD) risk levels of experimental type 2 diabetes patients provided with facilities for self-monitoring blood glucose and their counterparts without such facilities.Methods Sixty-one patients who had no prior experience in using glucometers were studied as intervention (n=30) and control (n=31) groups.The intervention group was trained in self-monitoring of blood glucose and documentation.Baseline blood glucose and fasting blood glucose were measured and the intervention patients were provided with glucometers and advised to self-monitor their fasting and postprandial blood glucose over six months.The 10-year CHD risk levels were determined with the United Kingdom Prospective Diabetes Study-derived risk engine calculator.Results The age and diabetes duration were similar in the two groups (P >0.05).The majority of the patients were unemployed or retired females with only a primary level education.After 3 months,the haemogolbin A1c (HbA1c) levels of the control patients remained unchanged ((7.8±0.3)% vs.(7.9±0.4)%,P >0.05) whereas the HbA1c levels of the intervention patients were significantly reduced from the baseline at three ((9.6±0.3)% vs.(7.8±0.3)%,P <0.001) and six ((9.2±0.4)% vs.(7.5±0.3)%,P <0.001) months.Interestingly,while the 10-year CHD risk level of the control group remained unchanged after three months,that of the intervention group was remarkably reduced at three and six months from the baseline level ((7.4±1.3)% vs.(4.5±0.9)%,P=0.056).Conclusion Self-monitoring of blood glucose in type 2 diabetes patients significantly improved glycaemic control and the CHD risk profile,suggesting that type 2 diabetes patients will potentially benefit from inclusion of glucose meters and testing strips in their health-care package.

    The objective of this study is to ascertain if higher normal fasting glucose levels are also an independent risk of developing diabetes in an Asian population, and we thus analysed data from a cohort of healthy Japanese workers. We used data from the non-randomised trial on health promotion intervention, High-risk and Population Strategy for Occupational Health Promotion (HIPOP-OHP) Study. Diabetes cases and those who had fasting blood glucose levels equal to or greater than 100 mg/dl at baseline were excluded, and the Cox proportional-hazards model was used for the analysis. During the four-year follow-up of 2212 participants, we found 37 diabetes cases. In the multivariable model, people with blood glucose levels in the 4th quartile had a higher risk of diabetes than those in the bottom quartile; the multivariable-adjusted odds ratio was 2.52. The risk of diabetes abruptly rose in persons with blood glucose levels higher than 94 mg/dl (fourth quartile). A significant linear trend was not observed in the 1st to 3rd quartiles (p=0.726). In conclusion, higher fasting glucose level was associated with the risk of diabetes, and we found a threshold in the association between fasting blood glucose levels and risk of diabetes in an Asian population.

    All forms of diabetes increase the risk of long-term complications. Blood glucose monitoring is of great importance for controlling diabetes procedure, preventing the complications and improving the patient's life quality. At present, the clinical blood glucose concentration measurement is invasive and could be replaced by noninvasive spectroscopy analytical techniques. The mid-infrared spectral region contains strong characteristic and well-defined absorption bands. Therefore, mid-infrared provides an opportunity for monitoring blood glucose invasively with only a few discrete bonds. Although the blood glucose concentration measurement using mid-infrared spectroscopy has a lot of advantages, the disadvantage is also obvious. The absorption in this infrared region is fundamental molecular group vibration. Absorption intensity is very strong, especially for biological molecules. In this paper, it figures out that the osmosis rate of glucose has a certain relationship with the blood glucose concentration. Therefore, blood glucose concentration could be measured indirectly by measuring the glucose exudate in epidermis layer. Human oral glucose tolerance tests were carried out to verify the correlation of glucose exudation in shallow layer of epidermis layer and blood glucose concentration. As it has been explained above, the mid-infrared spectral region contains well-defined absorption bands, the intensity of absorption peak around 1123 cm-1 was selected to measure the glucose and that around 1170 cm-1 was selected as reference. Ratio of absorption peak intensity was recorded for each set of measurement. The effect and importance of the cleaning the finger to be measured before spectrum measuring are discussed and also verified by experiment.

    Limited studies have examined the associations between air pollutants [particles with diameters of 10 μm or less (PM10), sulphur dioxide (SO2), and nitrogen dioxide (NO2)] and fasting blood glucose (FBG). We collected data for 27,685 participants who were followed during 2006 and 2008. Generalized Estimating Equation models were used to examine the effects of air pollutants on FBG while controlling for potential confounders. We found that increased exposure to NO2, SO2 and PM10 was significantly associated with increased FBG levels in single pollutant models (ppollutant models, the effects of SO2 were enhanced, while the effects of NO2 and PM10 were alleviated. The effects of air pollutants on FBG were stronger in female, elderly, and overweight people than in male, young and underweight people. In conclusion, the findings suggest that air pollution increases the levels of FBG. Vulnerable people should pay more attention on highly polluted days to prevent air pollution-related health issues.

    Full Text Available James W Reed Morehouse School of Medicine, Atlanta, GA, USA Abstract: SGLT2 inhibitors are glucose-lowering agents used to treat type 2 diabetes mellitus (T2DM. These agents target the kidney to promote urinary glucose excretion, resulting in improved blood glucose control. SGLT2-inhibitor therapy is also associated with weight loss and blood pressure (BP lowering. Hypertension is a common comorbidity in patients with T2DM, and is associated with excess morbidity and mortality. This review summarizes data on the effect of SGLT2 inhibitors marketed in the US (namely canagliflozin, dapagliflozin, or empagliflozin on BP in patients with T2DM. Boolean searches were conducted that included terms related to BP or hypertension with terms for SGLT2 inhibitors, canagliflozin, dapagliflozin, or empagliflozin using PubMed, Google, and Google Scholar. Data from numerous randomized controlled trials of SGLT2 inhibitors in patients with T2DM demonstrated clinically relevant reductions in both systolic and diastolic BP, assessed via seated office measurements and 24-hour ambulatory BP monitoring. Observed BP lowering was not associated with compensatory increases in heart rate. Circadian BP rhythm was also maintained. The mechanism of SGLT2 inhibitor-associated BP reduction is not fully understood, but is assumed to be related to osmotic diuresis and natriuresis. Other factors that may also contribute to BP reduction include SGLT2 inhibitor-associated decreases in body weight and reduced arterial stiffness. Local inhibition of the renin–angiotensin–aldosterone system secondary to increased delivery of sodium to the juxtaglomerular apparatus during SGLT2 inhibition has also been postulated. Although SGLT2 inhibitors are not indicated as BP-lowering agents, the modest decreases in systolic and diastolic BP observed with SGLT2 inhibitors may provide an extra clinical advantage for the majority of patients with T2DM, in addition to improving blood glucose

    This study examined the extent to which the potentially toxic lead particulates emitted from motor vehicles are absorbed by competitive cyclists. A time trial (n = 5), a road race (n = 5), and a sedentary control group (n = 5) were examined with respect to blood lead (PbB) levels. In the two cycling groups, the PbB levels were measured before and after (1) a time trial (80 km) held on a dual carriageway; and (2) a road race (120 km) which took place in a rural area. Mean (+/- SE) resting PbB levels for the sedentary subjects, time trialists, and road racers were 0.442 +/- 0.041, 0.490 +/- 0.111 and 0.384 +/- 0.061 mumol l-1 respectively (p > 0.05). Mean post-race PbB levels of the time trialists (0.528 +/- 0.046 mumol l-1) and road racers (0.346 +/- 0.024 mumol l-1) did not differ significantly from the pre-race levels (p > 0.05). However, after their respective races, the mean PbB level of the time trialists was higher than that of the road racers (p cycling (70% VO2 max) in a laboratory containing approximately 1 microgram m3 of airborne lead did not affect blood lead levels. All PbB levels compiled with EC regulations regarding lead exposure. Despite a positive relationship between the amount of training and the PbB levels (r = 0.64, p road racing.(ABSTRACT TRUNCATED AT 250 WORDS)

    In this study, we conducted a meta-analysis of self-controlled cohort studies comparing body weights, blood levels of lipids and fasting blood glucose levels before and after Ramadan taking into account gender differences. Several databases were searched up to June 2012 for studies showing an effect of Ramadan fasting in healthy subjects, yielding 30 articles. The primary finding of this meta-analysis was that after Ramadan fasting, low-density lipoprotein (SMD = -1.67, 95 % CI = -2.48 to -0.86) and fasting blood glucose levels (SMD = -1.10, 95 % CI = -1.62 to -0.58) were decreased in both sex groups and also in the entire group compared to levels prior to Ramadan. In addition, in the female subgroup, body weight (SMD = -0.04, 95 % CI = -0.20, 0.12), total cholesterol (SMD = 0.05, 95 % CI = -0.51 to 0.60), and triglyceride levels (SMD = 0.03, 95 % CI = -0.31, 0.36) remained unchanged, while HDL levels (SMD = 0.86, 95 % CI = 0.11 to 1.61, p = 0.03) were increased. In males, Ramadan fasting resulted in weight loss (SMD = -0.24, 95 % CI = -0.36, -0.12, p = 0.001). Also, a substantial reduction in total cholesterol (SMD = -0.44, 95 % CI = -0.77 to -0.11) and LDL levels (SMD = -2.22, 95 % CI = -3.47 to -0.96) and a small decrease in triglyceride levels (SMD = -0.35, 95 % CI = -0.67 to -0.02) were observed in males. In conclusion, by looking at this data, it is evident that Ramadan fasting can effectively change body weight and some biochemical parameters in healthy subjects especially in males compared to pre-Ramadan period.

    We report capillary flow of blood in a microchannel with differential wetting for the separation of a plasma from sample blood and subsequent on-chip detection of glucose present in a plasma. A rectangular polydimethylsiloxane microchannel with hydrophilic walls (on three sides) achieved by using oxygen plasma exposure enables capillary flow of blood introduced at the device inlet through the microchannel. A hydrophobic region (on all four sides) in the microchannel impedes the flow of sample blood, and the accumulated blood cells at the region form a filter to facilitate the separation of a plasma. The modified wetting property of the walls and hence the device performance could be retained for a few weeks by covering the channels with deionised water. The effects of the channel cross-section, exposure time, waiting time, and location and length of the hydrophobic region on the volume of the collected plasma are studied. Using a channel cross-section of 1000 × 400 μm, an exposure time of 2 min, a waiting time of 10 min, and a hydrophobic region of width 1.0 cm located at 10 mm from the device inlet, 450 nl of plasma was obtained within 15 min. The performance of the device was found to be unaffected (provides 450 nl of plasma in 15 min) even after 15 days. The purification efficiency and plasma recovery of the device were measured and found to be comparable with that obtained using the conventional centrifugation process. Detection of glucose at different concentrations in whole blood of normal and diabetic patients was performed (using 5 μl of sample blood within 15 min) to demonstrate the compatibility of the device with integrated detection modules.

    Background This study evaluated performance and product labeling of CONTOUR® USB, a new blood glucose monitoring system (BGMS) with integrated diabetes management software and a universal serial bus (USB) port, in the hands of untrained lay users and health care professionals (HCPs). Method Subjects and HCPs tested subject's finger stick capillary blood in parallel using CONTOUR USB meters; deep finger stick blood was tested on a Yellow Springs Instruments (YSI) glucose analyzer for reference. Duplicate results by both subjects and HCPs were obtained to assess system precision. System accuracy was assessed according to International Organization for Standardization (ISO) 15197:2003 guidelines [within ±15 mg/dl of mean YSI results (samples <75 mg/dl) and ±20% (samples ≥75 mg/dl)]. Clinical accuracy was determined by Parkes error grid analysis. Subject labeling comprehension was assessed by HCP ratings of subject proficiency. Key system features and ease-of-use were evaluated by subject questionnaires. Results All subjects who completed the study (N = 74) successfully performed blood glucose measurements, connected the meter to a laptop computer, and used key features of the system. The system was accurate; 98.6% (146/148) of subject results and 96.6% (143/148) of HCP results exceeded ISO 15197:2003 criteria. All subject and HCP results were clinically accurate (97.3%; zone A) or associated with benign errors (2.7%; zone B). The majority of subjects rated features of the BGMS as “very good” or “excellent.” Conclusions CONTOUR USB exceeded ISO 15197:2003 system performance criteria in the hands of untrained lay users. Subjects understood the product labeling, found the system easy to use, and successfully performed blood glucose testing. PMID:22027308

    Full Text Available Introduction: Diabetes Mellitus is a growing health problem in all over the world. Arctium Lappa has been used therapeutically in Europe, North America and Asia. Antioxidants and antidiabetic compounds have been found in the root of Arctium Lappa. This study intends to investigate the effects of Arctium Lappa root aqueous extract on glucose, insulin levels and Fasting Insulin Resistance Index in female rats with high sucrose diet. Methods: 40 female Wistar rats weighting 150-250(g were applied. After having a diet induced by sucrose 50% in drinking water for 5 weeks, the animals were randomly divided into two groups of control, sucrose induced, and three groups of sucrose induced along with Arctium Lappa root aqueous extract (50,100,200 mg/Kg (8 rats in each group. Treatment by extracts was used during 2 weeks (i.p. and 24 hours after the last treatment, heart blood samples were gathered. After Blood samples were centrifuged, fasting plasma glucose (12 h was determined by kit and fasting insulin concentration was assayed by Enzyme-linked immunosorbent assay (Elisa methods. Result: Glucose levels, insulin and FIRI in sucrose group significantly increased in comparison with control group. Glucose levels in aqueous extract groups; 50 mg/kg (116.14±16.64mg/dl and 200 mg/kg (90.66±22.58 mg/dl in comparison with sucrose group (140.5±18.73 mg/dl significantly decreased. Insulin level and FIRI in all of aqueous extract groups were significantly decreased (P<0.001 in comparison with sucrose group. Conclusions: Arctium Lappa root aqueous extracts in animal model has revealed significant decrease in blood glucose and insulin levels.

    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.

    Full Text Available In order to establish the effect of sampling hour and sex on blood glucose levels and total protein, there were monitored six Colombian native sheep for 3 days. The blood samples were taken by jugular venipuncture, after asepsis and stored at -20°C to its subsequent processing through Spectrophotometry. The results were tabulated in Excel and analyzed using statistical program SAS 9.1. The mean values found were: glucose 75.57 ± 27.5 mg/dL for females and 83.70 ± 37.7 mg/dL for males; total protein 8.47 ± 2.76 g/dL for females and 7.14 ± 3.26 g/dL for males; albumin 4.29 ± 1.41 g/dL for females and 3.83 ± 1.46 g/dL for males; globulin 4.62 ± 2.35 g/dL for females and 3.92 ± 2.45 g/dL for males. The day and the hour of sampling affect serum concentrations (p < 0.05 of evaluated metabolites, also there was variation of themself regarding sex (p < 0.05.

  20. The business of self-monitoring of blood glucose: a market profile.

    2009-09-01

    The market for self-monitoring of blood glucose (SMBG) approached $8.8 billion worldwide in 2008. Yet despite dramatic double-digit growth in sales of SMBG products since 1980, the business is now facing declining prices and slower dollar growth. Given that SMBG meters and test strips are viewed by consumers and insurers as essentially generic products, it will be extremely challenging for new market entrants to displace well-entrenched existing competitors without a truly innovative technology. Also, in the face of declining glucose test strip prices, market expansion can only occur through identification of more of the undiagnosed diabetes population and convincing existing diabetes patients to adopt glucose testing or to test more frequently. Ultimately, a combination of technology innovations, patient education, and economic incentives may be needed to significantly expand the SMBG market and build sustainable long-term dollar growth for SMBG vendors.

    Effects of aqueous extract of alligator pear seed on normal and alloxan-induced diabetic rats were investigated in 6 groups of rats (5 rats per group). Test groups were made diabetic with intra-peritoneal injection of alloxan and treated with 300 mg and 600 mg/kg body weight of alligator pear seed extract. Two non-diabetic groups were also administered with 300 mg and 600 mg/kg body weight extract. The levels of blood glucose were examined in all 6 experimental groups. In diabetic rats, blood glucose levels were significantly reduced (p<0.05) by 73.26-78.24% on consumption of the extracts, with greater effect exhibited by the 600 mg/kg extract. In normal rats, blood glucose levels were significantly reduced (p<0.05) by 34.68-38.9% on consumption of the seed extract. Histological studies showed a degenerative effect on the pancreatic islet cells of diabetic rats. The result suggested restorative (protective) effect of the extract on pancreatic islet cells. Administration of aqueous extract of alligator pear seed may contribute significantly to the reduction of blood glucose levels and can be useful in the treatment of diabetes.

    Full Text Available PURPOSE: This work investigates how short-term changes in blood glucose concentration affect the refractive components of the diabetic eye in patients with long-term Type 1 and Type 2 diabetes. METHODS: Blood glucose concentration, refractive error components (mean spherical equivalent MSE, J0, J45, central corneal thickness (CCT, anterior chamber depth (ACD, crystalline lens thickness (LT, axial length (AL and ocular aberrations were monitored at two-hourly intervals over a 12-hour period in: 20 T1DM patients (mean age ± SD 38±14 years, baseline HbA1c 8.6±1.9%; 21 T2DM patients (mean age ± SD 56±11 years, HbA1c 7.5±1.8%; and in 20 control subjects (mean age ± SD 49±23 years, HbA1c 5.5±0.5%. The refractive and biometric results were compared with the corresponding changes in blood glucose concentration. RESULTS: Blood glucose concentration at different times was found to vary significantly within (p0.05. Minor changes of marginal statistical or optical significance were observed in some biometric parameters. Similarly there were some marginally significant differences between the baseline biometric parameters of well-controlled and poorly-controlled diabetic subjects. CONCLUSION: This work suggests that normal, short-term fluctuations (of up to about 6 mM/l on a timescale of a few hours in the blood glucose levels of diabetics are not usually associated with acute changes in refractive error or ocular wavefront aberrations. It is therefore possible that factors other than refractive error fluctuations are sometimes responsible for the transient visual problems often reported by diabetic patients.

    Diabetes is a common metabolic disorder that is specified by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. The use of nonpharmacological treatments (herbal agents) is a new approach in the management of diabetes. The aim of this study was to investigate the effect of aqueous extract of alfalfa on blood glucose and serum lipids in alloxan-induced diabetic rats. In this study, 32 female rats (210–250 g) were used which were divided randomly into 4 groups including intact control group, diabetic control group, and 2 diabetic groups which received 250 and 500 mg/kg doses of aqueous extract of alfalfa, respectively. In the diabetic groups, alloxan-monohydrate was injected peritoneally to create diabetic condition. The two last groups orally received aqueous extract of alfalfa for 21 days. At the end of experiment, sugar, cholesterol, triglycerides, high-density and low-density lipoprotein, and aspartate aminotransferase (ALT) and alanine aminotransferase (AST) levels were measured in the samples. Consumption of aqueous alfalfa extract significantly reduced glucose, cholesterol, triglycerides, and low-density lipoprotein (LDL) levels in the diabetic rats but enhanced high-density lipoprotein (HDL) levels. ALT and AST liver enzyme levels were also reduced in blood. Histological examination showed that the aqueous alfalfa extract caused reconstruction of damaged liver and enhanced Langerhans islets’ diameter in pancreas. Therefore, all signs of diabetes were improved by oral administration of alfalfa in defined dose. PMID:26525173

    Full Text Available Objective: Diabetes mellitus affects every organ in the man including eyes, kidney, heart, and nervous system. Alcohol consumption is a widespread practice. As the effects of chronic alcohol consumption on diabetic state have been little studied, this study was conducted with the objective of evaluating the effect of alcohol in diabetic rats. Materials and Methods: For this study, the rats were divided into five groups (n = 6 in each group: normal control (NC, alcohol treatment (At, diabetic control (DC, diabetic plus alcohol treatment (D + At, diabetic plus glibenclamide treatment (D + Gli. Alcohol treatment was given to the diabetic rats for 30 days. During the period the blood glucose levels, and body weight changes were observed at regular intervals. The antioxidant enzymes like superoxide dismutase (SOD, catalase (CAT, and malondialdehyde (MDA levels were assayed in the liver and kidney tissues. Results: The blood glucose levels were significantly (P < 0.001 elevated and body weight significantly (P < 0.001 decreased in alcohol-treated diabetic rats. SOD and CAT activities were decreased and the MDA level increased significantly (P < 0.001 in alcohol-treated diabetic rats. Histopathological studies showed that alcohol damages the liver and kidney tissues in diabetic rats. Conclusion: These finddings concluded that the consumption of alcohol in diabetic rats worsens the condition. So the consumption of alcohol by diabetic subjects may be potentially harmful.

    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.

    The models of hyperlipidemia tilapia induced by high-fat diet were established to explore the effects of fermented mulberry leaves on serum lipid and blood glucose levels of hyperlipidemia tilapia ( Oreochromis niloticus) . A total of 450 male GIFT tilapia with the initial average body weight of 45 g were randomly divided into 5 groups with 3 replicates per group, and 30 fish in each replicate. The fish in normal control group were fed with a basal diet, and the other 4 groups were fed the basal diet ( model control group) and diets contained 7.5% and 15.0% fermented mulberry leaves ( low level fermented mulberry leaves group and high level fer-mented mulberry leaves group, respectively) , and 0.5% ginkgo flavone ( ginkgo flavone group) after the es-tablishment of the hyperlipidemia model, respectively. The experiment lasted for 8 weeks. The results showed as follows: after feeding 5 and 8 weeks, the body weight in model control group was significantly lower than that in normal control group, low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo flavone group (P0.05) . The serum total cholesterol ( TCHO) and low-density lipoprotein cholesterol ( LDL-C) contents and TCHO/high-density lipoprotein cholesterol ( HDL-C) in low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo fla-vone group were significantly lower than those in model control group (P0.05) . Compared with the model control group, the serum HDL-C content in high level fermented mulberry leaves group and ginkgo flavone group was significantly increased (P0.05). High-fat diet could significantly increase the blood glucose level in model control group, low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo flavone group (0 week, P0.05). These results indicate that fermented mulberry leaves can decrease the serum lipid and blood glucose levels, and enhance the antioxidant ability of

    Full Text Available OBJECTIVES: Pulse wave velocity (PWV is a surrogate end-point for cardiovascular morbidity and mortality. A plasma glucose value ≥155 mg/dl for the 1-hour post-load plasma glucose during an oral glucose tolerance test (OGTT is able to identify subjects with normal glucose tolerance (NGT at high-risk for type-2 diabetes (T2D and for subclinical organ damage. Thus, we addressed the question if 1-hour post-load plasma glucose levels, affects PWV and its central hemodynamic correlates, as augmentation pressure (AP and augmentation index (AI. METHODS: We enrolled 584 newly diagnosed hypertensives. All patients underwent OGTT and measurements of PWV, AP and AI. Insulin sensitivity was assessed by Matsuda-index. RESULTS: Among participants, 424 were NGT and 160 had impaired glucose tolerance (IGT. Of 424 NGT, 278 had 1-h post-load plasma glucose <155 mg/dl (NGT<155 and 146 had 1-h post-load plasma glucose ≥155 mg/dl (NGT≥155. NGT≥155 had a worse insulin sensitivity and higher hs-CRP than NGT<155, similar to IGT subjects. In addition, NGT ≥155 in comparison with NGT<155 had higher central systolic blood pressure (134±12 vs 131±10 mmHg, as well as PWV (8.4±3.7 vs 6.7±1.7 m/s, AP (12.5±7.1 vs 9.8±5.7 mmHg and AI (29.4±11.9 vs 25.1±12.4%, and similar to IGT. At multiple regression analysis, 1-h post-load plasma glucose resulted the major determinant of all indices of vascular stiffness. CONCLUSION: Hypertensive NGT≥155 subjects, compared with NGT<155, have higher PWV and its hemodynamic correlates that increase their cardiovascular risk profile.

    Full Text Available We describe how scale space methods can be used for quantitative analysis of blood glucose concentrations from type 2 diabetes patients. Blood glucose values were recorded voluntarily by the patients over one full year as part of a self-management process, where the time and frequency of the recordings are decided by the patients. This makes a unique dataset in its extent, though with a large variation in reliability of the recordings. Scale space and frequency space techniques are suited to reveal important features of unevenly sampled data, and useful for identifying medically relevant features for use both by patients as part of their self-management process, and provide useful information for physicians.

    Four male and four female zebra fish were crossed in all possible combinations, resulting in 389 offspring. These offspring were divided among four treatments: normoxia for 90 d, hypoxia for 90 d, normoxia for 30 d followed by hypoxia for 60 d, and hypoxia for 30 d followed by normoxia for 60 d. The effects of early oxygen environment, later oxygen environment, and genotype were then assessed with respect to zebra fish behavior, size, and blood glucose. Fish were tested in an arena where they could shoal with conspecifics before, during, and after the introduction of a novel stimulus. Blood glucose and size were also measured. Early oxygen environment influenced fish size, time spent swimming, and reactivity to a novel stimulus. Environmentally induced plasticity was predominate, with little evidence of among-sire variation for any of the measured parameters.

    In the current work we have developed a lab-on-a-chip containing embedded amperometric sensors in four microreactors that can be addressed individually and that are coated with crystalline surface protein monolayers to provide a continuous, stable, reliable and accurate detection of blood glucose. It is envisioned that the microfluidic device will be used in a feedback loop mechanism to assess natural variations in blood glucose levels during hemodialysis to allow the individual adjustment of glucose. Reliable and accurate detection of blood glucose is accomplished by simultaneously performing (a) blood glucose measurements, (b) autocalibration routines, (c) mediator-interferences detection, and (d) background subtractions. The electrochemical detection of blood glucose variations in the absence of electrode fouling events is performed by integrating crystalline surface layer proteins (S-layer) that function as an efficient antifouling coating, a highly-oriented immobilization matrix for biomolecules and an effective molecular sieve with pore sizes of 4 to 5 nm. We demonstrate that the S-layer protein SbpA (from Lysinibacillus sphaericus CCM 2177) readily forms monomolecular lattice structures at the various microchip surfaces (e.g. glass, PDMS, platinum and gold) within 60 min, eliminating unspecific adsorption events in the presence of human serum albumin, human plasma and freshly-drawn blood samples. The highly isoporous SbpA-coating allows undisturbed diffusion of the mediator between the electrode surface, thus enabling bioelectrochemical measurements of glucose concentrations between 500 μM to 50 mM (calibration slope δI/δc of 8.7 nA mM(-1)). Final proof-of-concept implementing the four microfluidic microreactor design is demonstrated using freshly drawn blood. Accurate and drift-free assessment of blood glucose concentrations (6. 4 mM) is accomplished over 130 min at 37 °C using immobilized enzyme glucose oxidase by calculating the difference between

    In this paper, a non-invasive blood glucose sensing system is presented using near infra-red(NIR) spectroscopy. The signal from the NIR optodes is processed using artificial neural networks (ANN) to estimate the glucose level in blood. In order to obtain accurate values of the synaptic weights of the ANN, inverse delayed (ID) function model of neuron has been used. The ANN model has been implemented on field programmable gate array (FPGA). Error in estimating glucose levels using ANN based on ID function model of neuron implemented on FPGA, came out to be 1.02 mg/dl using 15 hidden neurons in the hidden layer as against 5.48 mg/dl using ANN based on conventional neuron model.

    AIM: To investigate the effectiveness and safety of recombinant human growth hormone (rhGH) in postoperative patients.METHODS: A total of 48 consecutive patients undergoing abdominal operations were randomized to receive either subcutaneous rhGH (0.15 IU/kg) or placebo (menstruum) injections daily for 7 d after surgery. The two groups had similar nutritional intake. Blood samples for serum fibronectin, albumin, prealbumin, transferrin and the total lymphocyte count, as well as glucose levels were collected to study the rhGH effect. Basal laboratory evaluation, and nutritional status were estimated on d 1before as baseline and d 3 and 10 after operation using standard laboratory techniques. Nitrogen balance was measured from d 3 to 9 after operation.RESULTS: The cumulative nitrogen balance was significantly improved in rhGH group compared with the placebo group (11.37±16.82 vs -9.11±17.52, P = 0.0003).Serum fibronectin was also significantly higher in the rhGH group than in the placebo group (104.77±19.94vs 93.03±16.03, P<0.05), whereas changes in serum albumin, prealbumin, transferrin and total lymphocyte counts were not statistically significant. Mean blood glucose levels were significantly higher in the rhGH group from d 3 to 6 after operation.CONCLUSION: If blood glucose can be controlled, lowdose growth hormone together with hypocaloric nutrition is effective on improving positive nitrogen balance and protein conservation and safe is in postoperative patients.

    To investigate the effects of semiconductor laser acupoint irradiation on blood glucose, glycosylated hemoglobin and physical fitness in type 2 diabetes mellitus, 44 cases of type 2 diabetic patients were randomly divided into a control group and a treatment group. All patients in both groups were given a drug treatment. The Hegu, Quchi and Zusanli acupoints of patients in the treatment group were then irradiated daily for 15 d with a 10 MW semiconductor laser. Before and after treatment, patients in both groups underwent a variety of tests and measurements: a two-hour postprandial blood glucose test; a glycosylated hemoglobin test and body mass index (BMI), waist-to-hip ratio (WHR) and body fat percentage (BFP) measurements. The data detected after treatment greatly decreased in the treatment group and was significantly different from that in the control group. It is shown that the acupoint irradiation with a semiconductor laser can improve two-hour postprandial blood glucose, glycosylated hemoglobin and some physical fitness measurements in type 2 diabetes mellitus patients.

    Full Text Available Use of blood glucose (BG meters in the self-monitoring of blood glucose (SMBG significantly lowers the risk of diabetic complications. With several BG meters now commercially available, the International Organization for Standardization (ISO ensures that each BG meter conforms to a set degree of accuracy. Although adherence to ISO guidelines is a prerequisite for commercialization in Europe, several BG meters claim to meet the ISO guidelines yet fail to do so on internal validation. We conducted a study to determine whether the accuracy of the GlucoRx Nexus TD-4280 meter, utilized by our department for its cost-effectiveness, complied with ISO guidelines. 105 patients requiring laboratory blood glucose analysis were randomly selected and reference measurements were determined by the UniCel DxC 800 clinical system. Overall the BG meter failed to adhere to the ≥95% accuracy criterion required by both the 15197:2003 (overall accuracy 92.4% and 15197:2013 protocol (overall accuracy 86.7%. Inaccurate meters have an inherent risk of over- and/or underestimating the true BG concentration, thereby risking patients to incorrect therapeutic interventions. Our study demonstrates the importance of internally validating the accuracy of BG meters to ensure that its accuracy is accepted by standardized guidelines.

    A non-invasive blood glucose measurement sensor and the data process algorithm based on the metabolic energy conservation (MEC) method are presented in this paper. The physiological parameters of human fingertip can be measured by various sensing modalities, and blood glucose value can be evaluated with the physiological parameters by the multiple linear regression analysis. Five methods such as enter, remove, forward, backward and stepwise in multiple linear regression were compared, and the backward method had the best performance. The best correlation coefficient was 0.876 with the standard error of the estimate 0.534, and the significance was 0.012 (sig. regression equation was valid. The Clarke error grid analysis was performed to compare the MEC method with the hexokinase method, using 200 data points. The correlation coefficient R was 0.867 and all of the points were located in Zone A and Zone B, which shows the MEC method provides a feasible and valid way for non-invasive blood glucose measurement.

    Full Text Available Glucose concentration in the blood stream is a critical vital parameter and an effective monitoring of this quantity is crucial for diabetes treatment and intensive care management. Effective bio-sensing technology and advanced signal processing are therefore of unquestioned importance for blood glucose monitoring. Nevertheless, collecting measurements only represents part of the process as another critical task involves delivering the collected measures to the treating specialists and caregivers. These include the clinical staff, the patient’s significant other, his/her family members, and many other actors helping with the patient treatment that may be located far away from him/her. In all of these cases, a remote monitoring system, in charge of delivering the relevant information to the right player, becomes an important part of the sensing architecture. In this paper, we review how the remote monitoring architectures have evolved over time, paralleling the progress in the Information and Communication Technologies, and describe our experiences with the design of telemedicine systems for blood glucose monitoring in three medical applications. The paper ends summarizing the lessons learned through the experiences of the authors and discussing the challenges arising from a large-scale integration of sensors and actuators.

    Full Text Available Abstract Objective Diabetes mellitus type 2 (DM2 is a risk factor for coronary heart disease (CHD. While there is a clear correlation of fasting blood glucose (FBG and 2 h post-challenge blood glucose values (2h-BG with microvascular complications, the risk for CHD conferred by glucose dysregulation antecedent to DM2 is less clear. Therefore, we investigated associations of FBG and 2h-BG values with the prevalence of CHD assessed by coronary angiography as the most sensitive diagnostic tool. Research Design and Methods Coronary angiography was performed in 1394 patients without known DM. Capillary blood glucose was analyzed before and 2 h after an oral glucose tolerance test. Associations between FBG as well as 2h-BG levels and the risk for CHD were assessed by logistic regression analysis. Results 1064 (75% of patients were diagnosed with CHD. 204 (15% were diagnosed with so far unknown DM2, 274 (20% with isolated impaired fasting glucose (IFG, 188 (13% with isolated impaired glucose tolerance (IGT and 282 (20% with both, IGT and IFG. We found a continuous increase in the risk for CHD with fasting and post-challenge blood glucose values even in the subdiabetic range. This correlation did however not suggest clear cut-off values. The increase in risk for CHD reached statistical significance at FBG levels of > 120 mg/dl (Odds Ratio of 2.7 [1.3-5.6] and 2h-BG levels > 140 mg/dl (141-160 mg/dl OR 1.8 [1.1-2.9], which was however lost after adjusting for age, sex and BMI. Conclusions In our study population we found a continuous increased risk for CHD at fasting and 2h-BG levels in the sub-diabetic glucose range, but no clear cut-off values for cardiovascular risk.

    The effects of oligosaccharide and creatine (Cr) supplementation on glucose, lactic acid and urea nitrogen levels in blood and activity of serum creatine kinase (CK) were explored. Twenty CUBA male athletes were divided into 4 groups: group A (supplementation of Cr alone), group B (supplementation of oligosaccharide), group C (supplementation of oligosaccharide and Cr) and group D (placebo control group). By using orthogonal L4 table (2(3)), the experiment was performed. There were factors including oligosaccharide (carbohydrate, CHO), Cr and their correlation. Each factor had two levels: supplementation and no-supplementation. The results showed that the supplementation of CHO or Cr alone, combined supplementation of CHO and Cr could significantly reduce the glucose, urea nitrogen levels in blood and serum CK activity after competition in the athletes. Moreover, the effects of combined supplementation of CHO and Cr were more satisfactory. It was concluded that supplementation of CHO and Cr could promote the recovery of physical performance and athletic abilities after athletics in basketball athletes.

    Full Text Available Abstract Background A growing body of research suggests that elevated circulating levels of glucose and insulin accelerate risk factors for a wide range of disorders. Low-risk interventions that could suppress glucose without raising insulin levels could offer significant long-term health benefits. Methods To address this issue, we conducted two sequential studies, the first with two phases. In the first phase of Study 1, baseline fasting blood glucose was measured in 20 subjects who consumed 70 grams of sucrose in water and subsequently completed capillary glucose measurements at 30, 45, 60 and 90 minutes (Control. On day-2 the same procedure was followed, but with subjects simultaneously consuming a novel formula containing l-arabinose and a trivalent patented food source of chromium (LA-Cr (Treatment. The presence or absence of the LA-Cr was blinded to the subjects and testing technician. Comparisons of changes from baseline were made between Control and Treatment periods. In the second phase of Study 1, 10 subjects selected from the original 20 competed baseline measures of body composition (DXA, a 43-blood chemistry panel and a Quality of Life Inventory. These subjects subsequently took LA-Cr daily for 4 weeks completing daily tracking forms and repeating the baseline capillary tests at the end of each of the four weeks. In Study 2, the same procedures used in the first phase were repeated for 50 subjects, but with added circulating insulin measurements at 30 and 60 minutes from baseline. Results In both studies, as compared to Control, the Treatment group had significantly lower glucose responses for all four testing times (AUC = P P = Conclusions As compared to a placebo control, consumption of a LA-Cr formula after a 70-gram sucrose challenge was effective in safely lowering both circulating glucose and insulin levels.

    2009-02-01

    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.

    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.

    2016-01-01

    SGLT2 inhibitors are glucose-lowering agents used to treat type 2 diabetes mellitus (T2DM). These agents target the kidney to promote urinary glucose excretion, resulting in improved blood glucose control. SGLT2-inhibitor therapy is also associated with weight loss and blood pressure (BP) lowering. Hypertension is a common comorbidity in patients with T2DM, and is associated with excess morbidity and mortality. This review summarizes data on the effect of SGLT2 inhibitors marketed in the US (namely canagliflozin, dapagliflozin, or empagliflozin) on BP in patients with T2DM. Boolean searches were conducted that included terms related to BP or hypertension with terms for SGLT2 inhibitors, canagliflozin, dapagliflozin, or empagliflozin using PubMed, Google, and Google Scholar. Data from numerous randomized controlled trials of SGLT2 inhibitors in patients with T2DM demonstrated clinically relevant reductions in both systolic and diastolic BP, assessed via seated office measurements and 24-hour ambulatory BP monitoring. Observed BP lowering was not associated with compensatory increases in heart rate. Circadian BP rhythm was also maintained. The mechanism of SGLT2 inhibitor-associated BP reduction is not fully understood, but is assumed to be related to osmotic diuresis and natriuresis. Other factors that may also contribute to BP reduction include SGLT2 inhibitor-associated decreases in body weight and reduced arterial stiffness. Local inhibition of the renin–angiotensin–aldosterone system secondary to increased delivery of sodium to the juxtaglomerular apparatus during SGLT2 inhibition has also been postulated. Although SGLT2 inhibitors are not indicated as BP-lowering agents, the modest decreases in systolic and diastolic BP observed with SGLT2 inhibitors may provide an extra clinical advantage for the majority of patients with T2DM, in addition to improving blood glucose control.

    Objective For patients with diabetes, regular self-monitoring of blood glucose (SMBG) is essential to ensure adequate glycemic control. Therefore, accurate and reliable blood glucose measurements with SMBG systems are necessary. The international standard ISO 15197 describes requirements for SMBG systems, such as limits within which 95% of glucose results have to fall to reach acceptable system accuracy. The 2013 version of this standard sets higher demands, especially regarding system accuracy, than the currently still valid edition. ISO 15197 can be applied by manufacturers to receive a CE mark for their system. Research design and methods This study was an accuracy evaluation following ISO 15197:2013 section 6.3 of two recently updated SMBG systems (Contour * and Contour TS; Bayer Consumer Care AG, Basel, Switzerland) with an improved algorithm to investigate whether the systems fulfill the requirements of the new standard. For this purpose, capillary blood samples of approximately 100 participants were measured with three test strip lots of both systems and deviations from glucose values obtained with a hexokinase-based comparison method (Cobas Integra † 400 plus; Roche Instrument Center, Rotkreuz, Switzerland) were determined. Percentages of values within the acceptance criteria of ISO 15197:2013 were calculated. This study was registered at clinicaltrials.gov (NCT02358408). Main outcome Both updated systems fulfilled the system accuracy requirements of ISO 15197:2013 as 98.5% to 100% of the results were within the stipulated limits. Furthermore, all results were within the clinically non-critical zones A and B of the consensus error grid for type 1 diabetes. Conclusions The technical improvement of the systems ensured compliance with ISO 15197 in the hands of healthcare professionals even in its more stringent 2013 version. Alternative presentation of system accuracy results in radar plots provides additional information with certain advantages. In addition

    Although chronic hyperglycemia reduces insulin sensitivity and leads to impaired glucose utilization, short term exposure to high glucose causes cellular responses positively regulating its own metabolism. We show that exposure of L6 myotubes overexpressing human insulin receptors to 25 mm glucose for 5 min decreased the intracellular levels of diacylglycerol (DAG). This was paralleled by transient activation of diacylglycerol kinase (DGK) and of insulin receptor signaling. Following 30-min exposure, however, both DAG levels and DGK activity returned close to basal levels. Moreover, the acute effect of glucose on DAG removal was inhibited by >85% by the DGK inhibitor R59949. DGK inhibition was also accompanied by increased protein kinase C-alpha (PKCalpha) activity, reduced glucose-induced insulin receptor activation, and GLUT4 translocation. Glucose exposure transiently redistributed DGK isoforms alpha and delta, from the prevalent cytosolic localization to the plasma membrane fraction. However, antisense silencing of DGKdelta, but not of DGKalpha expression, was sufficient to prevent the effect of high glucose on PKCalpha activity, insulin receptor signaling, and glucose uptake. Thus, the short term exposure of skeletal muscle cells to glucose causes a rapid induction of DGK, followed by a reduction of PKCalpha activity and transactivation of the insulin receptor signaling. The latter may mediate, at least in part, glucose induction of its own metabolism.

    Full Text Available Background: Preterm neonates comprise the most heavily transfused group of patients, and about 85% of extremely low birth weight newborns receive a transfusion by the end of their hospital stay. The aim of this study was to assess the possible metabolic effects of RBC transfusion on preterm infants, especially during the first 2 weeks of life, and its relation to blood volume. Materials and Methods: This study was conducted on 40 preterm neonates with gestational age of less than or equal to 34 weeks. They received RBCs transfusion during first 2 weeks of life. Venous blood samples of infants were collected 2 to 4 hours before and 1 hour after the end of transfusion to evaluate hemoglobin (Hb level, hematocrit, acid-base, electrolytes, and glucose status. Then, infants were classified into two main groups: those who received RBCs volume less than or 20 ml/kg and those who received RBCs volum
