Effect of gastric bypass on BMI and lipid metabolism in type 2 diabetes mellitus.

Effect of gastric bypass on BMI and lipid metabolism in type 2 diabetes mellitus. Artif Cells Nanomed Biotechnol. 2020 Dec;48(1):903-911 Authors: Zhang C, Cai W, Zhao H, Zhu M, Cui J, Sun Z Abstract To compare the clinical efficacy of gastric bypass in obese patients with T2DM with different BMI. Serum leptin, adiponectin, triglyceride (TG), cholesterol (CHOL) were measured as the indicators to show clinical efficacy after laparoscopic gastric bypass surgery (LRYGB). For patients with high BMI and patients with low BMI, the therapeutic effect of LRYGB surgical diabetes is more significant. The postoperative remission rate of diabetes in the high BMI group was not correlated with the preoperative lipid metabolism index but was positively correlated with the postoperative lipid metabolism index CHOL, TG, leptin, adiponectin. The postoperative remission rate of diabetes in the low BMI group was positively correlated with the preoperative abnormal lipid metabolism of the patients, and positively correlated with the postoperative remission of leptin and adiponectin, but was not correlated with the postoperative remission of total CHOL and TG. The increase of serum adiponectin level and the decrease of leptin resistance after LRYGB surgery restored the metabolic balance of leptin and adiponectin, improved insulin resistance (IR), and thus improved blood glucose level. Therefore, LRYGB has a definite therapeutic effect on obese patients with T2DM, and elevated a...

In conclusion, overall and abdominal obesity have causal effects on T2DM risk and insulin resistance but no causal effect on fasting glucose. Individuals can substantially reduce their insulin resistance and T2DM risk through reduction of body fat mass and modification of body fat distribution.

CONCLUSION: European guidelines suggest general screening for risk factors, including analysis of lipid profiles in the population of 40-year-old males and 50-year-old or postmenopausal women. Our study documents high prevalence and incidence of CV risk factors together with insufficient control of the risk factors in Czech patients of this age range. This finding suggests that preventive examinations should be undertaken earlier (e.g., in 30-year-old males and 40-year-old women). Exact timing of the preventive check-ups to yield the best cost-benefit ratio needs to be verified. PMID: 32592555 [PubMed - as supplied by publisher]

Fatty acid-binding protein 4 (FABP4) acts as a novel adipokine, and elevated FABP4 concentration is associated with obesity, insulin resistance and atherosclerosis. Dipeptidyl peptidase-4 (DPP-4) inhibitors, a...

Type 2 diabetes mellitus (T2DM) has become an expanding global public health problem. Although the glucocorticoid receptor (GR) is an important regulator of glucose metabolism, the relationship between circulating glucocorticoids (GCs) and the features of T2DM remains controversial. Here, we show that 17-hydroxyprogesterone (17-OHP), an intermediate steroid in the biosynthetic pathway that converts cholesterol to cortisol, binds to and stimulates the transcriptional activity of GR. Hepatic 17-OHP concentrations are increased in diabetic mice and patients due to aberrantly increased expression of Cyp17A1. Systemic administr...

Abstract OBJECTIVES: Obesity is a major risk factor in aetiology of type 2 diabetes mellitus (T2DM). Leptin (LEP) is an anti-obesity hormone which regulates food intake, energy expenditure and glucose metabolism. The genetic variants in leptin and leptin receptor gene (LEPR) may play major role in the pathogenesis of T2DM and obesity. The current study aimed to investigate the association of polymorphisms in LEP (rs7799039, -2548G/A and rs2167270, 19G/A) and LEPR (rs1137101, 668A/G) gene with type 2 diabetes in North Indian Punjabi population. METHODS: A total of 817 subjects were included for the present cas...

Metabolic syndrome (MetS) is a condition characterized by the co-occurrence of metabolic risk factors for both type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) [1,2]. It includes various combinations of abdominal obesity, elevated fasting plasma glucose (FPG), atherogenic dyslipidemia with elevated triglyceride levels, low high-density lipoprotein (HDL) cholesterol levels, and elevated blood pressure (BP) [3]. The modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) definition is one of the most widely used criteria for MetS [4], because it uses available clinical variabl...

AbstractHeart failure with preserved ejection fraction (HFpEF) is a complex heterogeneous disease for which our pathophysiological understanding is still limited and specific prevention and treatment strategies are lacking. HFpEF is characterised by diastolic dysfunction and cardiac remodelling (fibrosis, inflammation, and hypertrophy). Recently, microvascular dysfunction and chronic low-grade inflammation have been proposed to participate in HFpEF development. Furthermore, several recent studies demonstrated the occurrence of generalized lymphatic dysfunction in experimental models of risk factors for HFpEF, including obe...

Abstract Multiple myeloma (MM) is a haematological malignancy arising from monoclonal proliferation of plasma cells in the bone marrow, resulting in the presence of paraproteins or M-protein in serum. The involvement of paraproteins produced by malignant plasma cells in the development of hyperlipidaemia and low-HDL cholesterol has been described, as has an association with MM and obesity, hypertension, and type 2 diabetes mellitus, and insulin resistance, that is, features of the metabolic syndrome (MS). There is an association between MS components, inflammatory cytokines, and the development of MM, and some dru...

We reported findings from the first 8-month pilot phase of the South African diabetes prevention program. The study was conducted across eight townships (four black and four mixed-ancestry communities) in Cape Town, South Africa, between August 2017 and March 2018. Participants were recruited using both random and self-selected sampling techniques because the former approach proved to be ineffective; <10% of randomly selected individuals consented to participate. Non-laboratory-based diabetes risk screening, using the African diabetes risk score, and based on targeted population specific cut-offs, identified potenti...

This study is par for the course, looking at Japanese Olympic participants. Interestingly, it hints at the upper end of the dose-response curve for physical activity, in that a longer career as a professional athlete may be detrimental in comparison to lesser degrees of exercise and training. From this large, retrospective cohort study targeting 3546 Japanese Olympic athletes, we observed significant lower mortality among Olympians compared with the Japanese general population. The overall standardised mortality ratio (SMR) was 0.29. The results were consistent with previous studies conducted in other non-Asian co...
