Design: A population-based temporal-trend study using the database of the Ecuadorian National Death Registry. Methods: Crude and age-adjusted mortality rates were calculated, and age-related mortality rates were standardized with the world population (WHO). Trends in age-standardized mortality rates were estimated by join point regression analysis. The trends were expressed as annual percentage change (APC) and average annual percentage change (AAPC). Results: In total, TC caused 2,107 deaths (1,475 women and 632 men) in the selected period. The mortality in men showed a statistically non-significant decrease. The estimated APC was −0.4% (P = 0.70), and the average AAPC was −0.4% (P = 0.70) without any identified jointpoint. In women, the mortality decreased significantly between 1990 and 1998, with the estimated APC being −6.6% (P < 0.05). However, it increased significantly from 1998 to 2016, with the estimated APC of 5.4% (P < 0.05), and a jointpoint was identified; the AAPC was 1.4 (P = 0.30). Conclusions: While TC mortality in Ecuadorian men showed a decrease, that in Ecuadorian women showed an initial decrease and a final increase. Our findings can be contrasted with the global data, which show decreases in TC mortality in both sexes.","PeriodicalId":73731,"journal":{"name":"Journal of endocrinology and diabetes","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46841566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Was evaluated by using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay. The extract showed significant activities in all antioxidant assays compared to the reference antioxidant ascorbic acid in a dose dependent manner. Phyllanthus amarus significantly reduced the blood glucose level starting on the second week. Furthermore, the extract of P amarus showed significant increase in plasma insulin and tissue glycogen contents. The antidyslipidemic effect was demonstrated by a significant reduction in plasma total cholesterol (TC), triglycerides (TG), and low density lipoprotein-cholesterol (LDL-C), while the cardio-protective lipid, high density lipoprotein-cholesterol (HDL-C), was increased. Phyllanthus amarus also modulated the activities of carbohydrate-metabolizing enzymes by significantly increasing the activity of hexokinase and pyruvate kinase (p<0.05) and significantly reducing the activity of glucose-6-phosphatase, fructose-1,6-diphosphatase and glycogen phosphorylase (p<0.05). Phyllanthus amarus administration up-regulated mrna expression of Glucose Transporter-2 (GLUT-2), and increased lipolysis and cholesterol metabolism through up-regulation of lipoprotein lipase (LPL), Sterol Responsible Element Binding Protein-1a (STREBP-1a) expression.

It is also routinely carried out in the management of diseases associated with a more or less pronounced disturbance of glucose intolerance. According to the current guidelines, during OGTT glycemia is measured before and two hours after the administration of glucose. In pregnancy, three measurements are obligatory (0’, 60’, 120’). When additional indications are present, glycemia is assessed also 30 minutes after the administration of glucose and when reactive hypoglycemia is suspected, the test is extended to 180 minutes. As of late, it is becoming a more and more common practice to measure blood glucose also 60 minutes post-administration. This technique is more reliable for the assessment of glucose tolerance disturbance. Self-observations also indicate this. It seems sensible to introduce a recommendation of such measurement as a routine practice.","PeriodicalId":73731,"journal":{"name":"Journal of endocrinology and diabetes","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67332462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Throughout gestation there is a close relationship between maternal and fetal blood glucose concentrations. Maternal hyperglycemia leads to hyperglycemia of the fetus, stimulating the fetal pancreas to synthesize excessive amounts of insulin. At the time of delivery, after separation of the placenta, the flow of glucose to the newborn that is appropriate for hyperglycemia is suddenly interrupted. Excessive insulin production in the fetus in response to maternal hyperglycemia can cause severe hypoglycaemia during the neonatal period. It is a very common complication of maternal diabetes. In healthy children during the first 4-6 postnatal hours there is a physiological decrease in glucose level from the mother’s blood level to about 2.5 mmol / l (45 mg / dl). This is related to still not fully developed adaptive mechanisms. There is strong evidence that good glycemic control is essential for an optimal outcome of pregnancy in diabetic women. Despite advances in perinatal care, infants of diabetic mothers remain at risk for a multitude of physiologic, metabolic, and congenital complications such as preterm birth, macrosomia, respiratory distress, hypoglycemia, hypocalcemia, hyperbilirubinemia, hypertrophic cardiomyopathy, and congenital anomalies, particularly of the central nervous system.","PeriodicalId":73731,"journal":{"name":"Journal of endocrinology and diabetes","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49273692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The association between this nutrient and glucose metabolism has been documented in numerous studies with animals and humans. Vitamin A is required for the maintenance of pancreatic β and α cell mass and for glucose-stimulated insulin secretion. Moreover, the vitamin and its metabolites modulate insulin resistance. Many studies indicate the role of vitamin A in the pathogenesis of type 1 diabetes through its effect on regulation of autoimmune processes and β cell mass as well as in type 2 diabetes through its effect on insulin resistance. Retinol ‘family’ plays an important role in maintaining the correct glucose metabolism, so it is essential to provide the homeostasis of this nutrients in the body.

Accumulating evidence suggests that even mild primary hyperparathyroidism (PHPT) has an elevated risk for CVD. We aimed to investigate plasma PTX3 levels before and after parathyroidectomy in patients with primary hyperparathyroidism and determine its relationship with cardiovascular risk factors Material and Method: Twenty-nine patients with PHPT and 26 healthy controls were enrolled in the study. Anthropometric and laboratory parameters were recorded both before and 6 months after parathyroidectomy. Serum PTX3 levels were measured using a human PTX3 enzyme-linked immunosorbent assay. Results: Plasma PTX3 concentrations were similar between before and after parathyroidectomy and control group (10.97 ± 16.0, 11.97 ± 11.49, 7.88 ± 9.48, respectively, p>0.05). Systolic blood pressure, diastolic blood pressure, carotid intima-media thickness (CIMT) and calcium, parathormone, fasting plasma glucose, alkaline phosphatase concentrations were higher in the PHPT group (p<0.05). Creatinine and phosphorus concentrations were higher in the control group (p<0.05). PTX3 was not correlated with cardi-metabolic risk factors except body mass index (BMI) (r2:0.414, p:0.0253). Conclusion: Plasma PTX3 was not increased as well was not changed after parathyroidectomy in patients with PHPT. The PTX3 was correlated with BMI; however, it was not associated with other cardio-metabolic risk factors including DBP, CIMT, and CRP.
