Abstract Context The rate of glucose metabolism changes drastically after partial pancreatectomy. Objective This work aims to analyze changes in patients’ glucose metabolism and endocrine and exocrine function before and after partial pancreatectomy relative to different resection types (Kindai Prospective Study on Metabolism and Endocrinology after Pancreatectomy: KIP-MEP study). Methods A series of 278 consecutive patients with scheduled pancreatectomy were enrolled into our prospective study. Of them, 109 individuals without diabetes, who underwent partial pancreatectomy, were investigated. Data were compared between patients with pancreaticoduodenectomy (PD, n = 73) and those with distal pancreatectomy (DP, n = 36). Results Blood glucose levels during the 75-g oral glucose tolerance test (75gOGTT) significantly decreased after pancreatectomy in the PD group (area under the curve [AUC] –9.3%, P < .01), and significantly increased in the DP population (AUC + 16.8%, P < .01). Insulin secretion rate during the 75gOGTT and glucagon stimulation test significantly decreased after pancreatectomy both in the PD and DP groups (P < .001). Both groups showed similar homeostasis model assessment of insulin resistance (HOMA-IR) values after pancreatectomy. Decrease in exocrine function quality after pancreatectomy was more marked in association with PD than DP (P < .01). Multiple regression analysis indicated that resection type and preoperative HOMA-IR independently influenced glucose tolerance-related postoperative outcomes. Conclusions Blood glucose levels after the OGTT differed markedly between PD and DP populations. The observed differences between PD and DP suggest the importance of individualization in the management of metabolism and nutrition after partial pancreatectomy.

Objective: The aim of this work was to evaluate the antihyperglycemic activity of aerial parts aqueous extract (A.P.A.E) of Mentha pulegium (M. pulegium) on blood glucose levels in normal and streptozotocin(STZ)-induced diabetic rat. The glucose tolerance was evaluated in normal rats. Moreover, the histological sections and morphometric analysis at the liver and pancreas have been carried out in this investigation both in normal and STZ-diabetic rats. Methods: The effect of A.P.A.E of M. pulegium (20 mg/kg) on blood glucose levels was investigated in normal and diabetic rats (n=6). Histopathological changes in liver and pancreas were examined under phase contrast microscope and a preliminary screening for various bioactive constituents was realized according to standard methods. Key Findings: Both single and repeated oral administration of A.P.A.E (20 mg/kg) caused a significant reduction in blood glucose levels in STZ-diabetic rats (p<0.0001). The morphometric analysis and histological sections realized in pancreas and liver have showed the beneficial effect of the A.P.A.E in cellular population. According to oral glucose tolerance test (OGTT), the aqueous extract has revealed an improvement of glucose tolerance in normal rat. Furthermore, the preliminary phytochemical screening of A.P.A.E of M. pulegium has demonstrated the presence of various metabolite compounds including polyphenols, flavonoids, terpenoids tannins, cyanidins, sesquiterpenes, and glycosides. Conclusion: We conclude that the A.P.A.E of M. pulegium (20 mg/kg) exhibits a potent antihyperglycemic activity in STZ diabetic rats.

<p>The purpose of this study is to evaluate the hypoglycaemic properties and preliminary phytochemical screening of <em>Uveria chamae</em>. The hypoglycaemic properties of <em>Uveria chamae</em> was assessed on normoglycaemic rat that received single dose of the extract at 250 and 500 mg/kg body weight and blood glucose levels estimated at 2, 4, and 6 hours (single dose study). The hypoglycaemic property of the extract was also evaluated in normoglycemic rats by oral glucose tolerance test. Phytochemical screening of the extract for the presence of secondary metabolites was performed with standard methods. The extract showed a significant (p&lt;0.05) reduction in blood glucose levels at 2h and 6h compared to control.  The oral glucose tolerance test  result also showed a significant decrease (p&lt;0.05) in blood glucose levels . The study showed that the extract, <em>Uveria chamae</em> has hypoglycaemic properties which may be accounted for by the presence of the phytochemicals.</p><p> </p>

Background: Gestational diabetes mellitus (GDM) is a condition, in which women develop high blood sugar levels during pregnancy without having diabetes. Evidence on the effects of probiotics on the blood glucose levels of women with GDM is inconsistent. Objective: The present study aimed to investigate the effects of probiotics on the blood glucose levels of pregnant women. Methods: Online databases, such as PubMed, Cochrane, and Excerpta Medica Database (EMBASE) were searched for randomized controlled trials (RCTs) published before July 2018. Trials had to meet the inclusion criteria of our study. Methodological quality and risk bias were independently assessed by two reviewers. Data were pooled using a random effects model and were expressed as the mean difference (MD) and 95% confidence interval (CI). Heterogeneity was evaluated and quantified as I2. Results: In total, 12 RCTs were included in this study. Studies have shown that the use of probiotics significantly reduced the fasting blood glucose (FBG) level (MD: −0.10 mmol/L; 95% CI: −0.19, −0.02), insulin concentration (MD: −2.24 μIU/mL; 95% CI: −3.69, −0.79), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) score (MD: −0.47; 95% CI: −0.74, −0.21), and Homeostasis model of assessment-estimated β cell function (HOMA-B) score (MD: −20.23; 95% CI: −31.98, −8.49) of pregnant women. In a subgroup analysis, whether the blood glucose-lowering effect of probiotics influenced the diagnosis of pregnant women with GDM was assessed. The results showed that probiotics had significantly reduced the fasting blood glucose (FBG) level (MD: −0.10 mmol/L; 95% CI: −0.17, −0.04) and HOMA-IR score (MD: −0.37; 95% CI: −0.72, −0.02) of pregnant women who were not diagnosed with GDM. Conclusion: Probiotics reduce the blood glucose level of pregnant women, especially without GDM diagnosis. However, further research using RCTs must be conducted to validate the results of the present study.

We’ve studied a carbohydrate metabolism in morbidly obese (MO) patients and the patients after bariatric surgery. The patients of the 1st group had BMI40 (n=22) and no history of diabetes mellitus. Patients after biliopancreatic diversion (BPD) performed for MO were included in the 2nd group (n=23). The 3rd group was a control group of normal weight healthy subjects (n=22). Blood glucose levels, insulin, GLP-1, GIP and glucagon during the OGTT (with 75 g of glucose) at 0, 30, 60 and 120 minutes were measured in all patients. In MO group fasting glucose levels were the highest. Impaired glucose metabolism was revealed in 68.2% of patients (n=10). Impaired fasting glucose (IFG) was diagnosed in 4 cases (18.2%), impaired glucose tolerance (IGT) in 11 patients (50%). In the BPD postprandial blood glucose levels (120 min) were lower if compared to the other groups. In 4 individuals (17.4%) we found postprandial hypoglycemia (2.8 mmol/l). Patients of the MO group had the highest fasting insulin levels and HOMA-IR (p0.001). The maximum of insulin concentration was seen on minute 30 of the OGTT in the 2nd and 3rd groups, and it was significantly higher in the post-bariatric patients (p=0.026). In MO group the maximum of the plasma insulin levels were on the 60th minute and were still elevated after 120 minutes. Fasting and stimulated (on the 30th minute) levels of GLP-1 were significantly higher after BPD (р=0.037 and p=0.022 at 0 and 30 min, respectively). Morbidly obese patients had higher fasting and stimulated GIP. Fasting glucagon concentrations were similar in the surgical and control groups, while the people with MO had higher initial levels of glucagon (p=0.013) and it was not suppressed during the OGTT (p=0.076). Glucose intolerance and insulin resistance incidence was higher in MO patients. Hyperglucagonemia, increased GIP and decreased GLP-1 levels are observed in MO patients. Stimulated plasma insulin and GLP-1 concentrations were significantly increased in patients who underwent BPD, and may cause postprandial hypoglycemia.

Background: Emerging patterns in epidemiological transitions have led to increased risk for Non-Communicable Diseases and infectious conditions globally. Diabetes mellitus (DM) in a population is one such risk factor that could lead to the development of Tuberculosis (TB) due to weakened immune functions in affected persons, with implications for mortality. If not diagnosed early, DM also leads to poor treatment outcomes in TB. Objective: To assess the prevalence of DM and impaired glucose tolerance (pre-diabetes) among newly diagnosed tuberculosis cases in Ijebu-Ode Local Government Area of Ogun State, Nigeria. Methods: This cross-sectional study was conducted among 100 newly diagnosed Pulmonary TB patients in ljebu-Ode LGA. The patients were selected from four health facilities and were screened for elevated Fasting Blood Glucose levels using a laboratory spectrophotometer (glucose oxidase method). Results: The mean age of the 100 study participants was 33 years (± 9.82), with ages within 19 -62 years. Eleven (11.0%) had elevated blood glucose levels suggestive of DM, while 20 (20.0%) had impaired fasting blood glucose levels. Among these 31 patients, 18 (58.0%) were males while 13 (42.0%) were females. The modal ages were within 20-39 years. Conclusion: Screening for DM by healthcare providers should be routinely conducted before commencing TB patients on treatment. This will aid early detection, improve treatment outcomes of TB and prevent mortality among patients with these co-morbidities.

Background: A body mass index ≥95 percentile increases 40 times the risk of diabetes. The hyperinsulinemia secondary to the resistance of insulin and obesity is associated to the development of acanthosis nigricans. The objective of current study was to associate acanthosis nigricans with childhood obesity with alterations in the curve of glucose tolerance.Methods: In current study 90 children were evaluated with obesity and acanthosis nigricans of which only 34 concluded the study. Glucose, cholesterol and triglycerides levels were determined while in fasting state, and glucose tolerance curve was conducted. The statistical analysis was done by determining X², Fisher´s test and U, Mann Whitney test.Results: Statistically significant difference was found between glucose levels at 2 hours and the presence of obesity and acanthosis nigricans (p<0.01).Conclusions: It is important that all the children with obesity and Acanthosis nigricans apply for a curve of glucose tolerance.
