Association of wrist circumference with metabolic dysfunction associated fatty liver disease in the KADEM cohort.

Introduction: Metabolic dysfunction-associated fatty liver disease (MAFLD) is linked to metabolic dysfunction and to an increased risk of cardiovascular diseases. The early detection of individuals at high risk of MAFLD is essential for timely interventions. This study explores the association between wrist circumference and MAFLD among participants in the Kuwait Adult Diabetes and Epidemiological Multidisciplinary (KADEM) program, aiming to evaluate wrist circumference as a potential noninvasive diagnostic marker.

Investigating the Role of GDF-15 in Diabetes and Obesity: A Comprehensive Analysis of a Cohort from the KDEP Study.

Growth differentiation factor 15 (GDF-15), a member of the transforming growth factor-β (TGF-β) superfamily, is upregulated under cellular stress conditions and has emerged as a potential biomarker for metabolic disorders. However, its expression in relation to diabetes and obesity across different demographic groups remains understudied. This study investigated the association between plasma GDF-15 levels, diabetes mellitus, and obesity in individuals of varying ages, ethnicities, and genders.

Empagliflozin Enhances Hepatic Glucose Production and Reduces Total-Body Norepinephrine Turnover Rate: A Randomized Trial.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) cause an increase in hepatic glucose production (HGP). We previously showed that SGLT2i cause a rapid (within 4 h) increase in the total-body norepinephrine (NE) turnover rate, which could explain the increase in HGP. Because the increase in HGP caused by SGLT2i is long-lasting, we examined the long-term effect of SGLT2i on the NE turnover rate.

Glycemic and non-glycemic benefits of initial triple therapy versus sequential add-on therapy in patients with new-onset diabetes: results from the EDICT study.

Introduction: To compare carotid intima-media thickness (cIMT) and liver fat content in subjects who maintained good glycemic control for 6 years on initial triple therapy with metformin/exenatide/pioglitazone versus sequential add-on therapy with metformin followed with glipizide and basal insulin in subjects with new-onset diabetes.

Research Design And Methods: Liver fat content and cIMT were compared among patients with T2DM who received initial triple therapy with metformin/pioglitazone/exenatide (n=29) versus metformin, followed by stepwise addition of glipizide and then insulin glargine (n=26) and who maintained HbA1c<6.5% for 6 years in Efficacy and Durability of Initial Combination Therapy for Type 2 Diabetes.

Circulating Isthmin-1 Levels and Their Relationship with Diabetes and Metabolic Diseases in Kuwaiti Adults.

Obesity and type 2 diabetes (T2D) are associated with significant alterations in various metabolic biomarkers. Isthmin-1 (Ism1) has recently emerged as a potential marker of metabolic health and was shown in animal studies to associate with metabolic-associated fatty liver disease (MAFLD). In this study, we aimed to investigate the circulatory levels of Ism1 in individuals with obesity compared to non-obese individuals and evaluate their association with insulin resistance, MAFLD, and T2D.

Effect of weight-maintaining ketogenic diet on glycemic control and insulin sensitivity in obese T2D subjects.

Introduction: Low carbohydrate ketogenic diets have received renewed interest for the treatment of obesity and type 2 diabetes. These diets promote weight loss, improve glycemic control, and reduce insulin resistance. However, whether the improvements in glycemic control and insulin sensitivity are secondary to the weight loss or result from a direct effect of hyperketonemia is controversial.

Pre-Prediabetes: Insulin Resistance Is Associated With Cardiometabolic Risk in Nonobese Patients (STOP DIABETES).

Context: Prior studies have demonstrated glycemic and cardiometabolic risk in the prediabetic state.

Objective: This work aims to examine if insulin resistance (IR) is associated with markers of glycemic, cardiometabolic, and atherosclerotic risk in nonobese, nonprediabetic individuals compared to insulin-sensitive (IS) individuals matched for body mass index (BMI), sex, and age.

Methods: Of 1860 patients from the STOP DIABETES study, 624 had normal fasting plasma glucose, BMI less than 30, and glycated hemoglobin A1c (HbA1c) less than 5.

Managing insulin resistance: the forgotten pathophysiological component of type 2 diabetes.

Glucagon-like peptide-1 (GLP-1) receptor agonists have gained widespread use in the treatment of individuals with type 2 diabetes because of their potent weight loss promoting effect, ability to augment β-cell function, and cardiovascular protective effects. However, despite causing impressive weight loss, GLP-1 receptor agonists do not normalise insulin sensitivity in people with type 2 diabetes and obesity, and the long-term effects of this class of antidiabetic medication on muscle mass, frailty, and bone density have been poorly studied. Although GLP-1 receptor agonists improve insulin sensitivity secondary to weight loss, the only true direct insulin-sensitising drugs are thiazolidinediones.

Ethnic Variations in the Levels of Bone Biomarkers (Osteoprostegerin, Receptor Activator of Nuclear Factor Kappa-Β Ligand and Glycoprotein Non-Metastatic Melanoma Protein B) in People with Type 2 Diabetes.

The global incidence of Type 2 diabetes (T2D) is on the rise, fueled by factors such as obesity, sedentary lifestyles, socio-economic factors, and ethnic backgrounds. T2D is a multifaceted condition often associated with various health complications, including adverse effects on bone health. This study aims to assess key biomarkers linked to bone health and remodeling-Osteoprotegerin (OPG), Receptor Activator of Nuclear Factor Kappa-Β Ligand (RANKL), and Glycoprotein Non-Metastatic Melanoma Protein B (GPNMB)-among individuals with diabetes while exploring the impact of ethnicity on these biomarkers.

Evaluating the correlation of sclerostin levels with obesity and type 2 diabetes in a multiethnic population living in Kuwait.

Obesity and Type 2 Diabetes Mellitus (T2DM) are intricate metabolic disorders with a multifactorial etiology, often leading to a spectrum of complications. Recent research has highlighted the impact of these conditions on bone health, with a particular focus on the role of sclerostin (SOST), a protein molecule integral to bone metabolism. Elevated circulating levels of SOST have been observed in patients with T2DM compared to healthy individuals.

Real-world effectiveness of sodium-glucose cotransporter-2 inhibitors on the progression of chronic kidney disease in patients without diabetes, with and without albuminuria.

Aim: To examine the renal effects of sodium-glucose cotransporter-2 (SGLT2) inhibition among non-diabetic individuals with chronic kidney disease (CKD) in a real-world setting.

Methods: We collected de-identified data on adults without diabetes and with an estimated glomerular filtration rate (eGFR) of 25-60 mL/min/1.73 m, who initiated the SGLT2 inhibitors dapagliflozin or empagliflozin between September 2020 and November 2022 at Maccabi Healthcare Services, an Israeli health maintenance organization.

International Diabetes Federation Position Statement on the 1-hour post-load plasma glucose for the diagnosis of intermediate hyperglycaemia and type 2 diabetes.

Many individuals with intermediate hyperglycaemia (IH), including impaired fasting glycaemia (IFG) and impaired glucose tolerance (IGT), as presently defined, will progress to type 2 diabetes (T2D). There is confirmatory evidence that T2D can be prevented by lifestyle modification and/or medications, in people with IGT diagnosed by 2-h plasma glucose (PG) during a 75-gram oral glucose tolerance test (OGTT). Over the last 40 years, a wealth of epidemiological data has confirmed the superior value of 1-h plasma glucose (PG) over fasting PG (FPG), glycated haemoglobin (HbA) and 2-h PG in populations of different ethnicity, sex and age in predicting diabetes and associated complications including death.

Empagliflozin Reduces Liver Fat in Individuals With and Without Diabetes.

Objective: To examine the effect of empagliflozin on liver fat content in individuals with and without type 2 diabetes (T2D) and the relationship between the decrease in liver fat and other metabolic actions of empagliflozin.

Research Design And Methods: Thirty individuals with T2D and 27 without were randomly assigned to receive in double-blind fashion empagliflozin or matching placebo (2:1 ratio) for 12 weeks. Participants underwent 75-g oral glucose tolerance testing and measurement of liver fat content with MRS before therapy and at study end.

Plasma insulin is required for the increase in plasma angiopoietin-like protein 8 in response to nutrient ingestion.

Background: Plasma levels of angiopoietin-like protein 8 (ANGPTL8) are regulated by feeding and they increase following glucose ingestion. Because both plasma glucose and insulin increase following food ingestion, we aimed to determine whether the increase in plasma insulin and glucose or both are responsible for the increase in ANGPTL8 levels.

Methods: ANGPTL8 levels were measured in 30 subjects, 14 with impaired fasting glucose (IFG), and 16 with normal fasting glucose (NFG); the subjects received 75g glucose oral Glucose tolerance test (OGTT), multistep euglycaemic hyperinsulinemic clamp and hyperglycaemic clamp with pancreatic clamp.

Distinct Mechanisms Responsible for the Increase in Glucose Production and Ketone Formation Caused by Empagliflozin in T2DM Patients.

Objective: To examine the mechanisms responsible for the increase in glucose and ketone production caused by empagliflozin in patients with type 2 diabetes mellitus (T2DM).

Research Design And Methods: Twelve subjects with T2DM participated in two studies performed in random order. In study 1, endogenous glucose production (EGP) was measured with 8-h infusion of 6,6,D2-glucose.

Pioglitazone reduces epicardial fat and improves diastolic function in patients with type 2 diabetes.

Aims: To examine the effect of pioglitazone on epicardial (EAT) and paracardial adipose tissue (PAT) and measures of diastolic function and insulin sensitivity in patients with type 2 diabetes mellitus (T2DM).

Methods: Twelve patients with T2DM without clinically manifest cardiovascular disease and 12 subjects with normal glucose tolerance (NGT) underwent cardiac magnetic resonance imaging to quantitate EAT and PAT and diastolic function before and after pioglitazone treatment for 24 weeks. Whole-body insulin sensitivity was measured with a euglycaemic insulin clamp and the Matsuda Index (oral glucose tolerance test).

FGF21 contributes to metabolic improvements elicited by combination therapy with exenatide and pioglitazone in patients with type 2 diabetes.

Fibroblast growth factor 21 (FGF21) is increased acutely by carbohydrate ingestion and is elevated in patients with type 2 diabetes (T2D). However, the physiological significance of increased FGF21 in humans remains largely unknown. We examined whether FGF21 contributed to the metabolic improvements observed following treatment of patients with T2D with either triple (metformin/pioglitazone/exenatide) or conventional (metformin/insulin/glipizide) therapy for 3 yr.

Type 2 diabetes subgroups and response to glucose-lowering therapy: Results from the EDICT and Qatar studies.

Aim: To examine the efficacy of glucose-lowering medications in subgroups of patients with type 2 diabetes mellitus (T2DM).

Research Design And Methods: Cluster analysis was performed in participants in the Efficacy and Durability of Initial Combination Therapy for Type 2 Diabetes (EDICT) study and the Qatar study using age, body mass index (BMI), glycated haemoglobin (HbA1c), and homeostatic model assessment of insulin resistance (HOMA-IR) and beta-cell function (HOMA-β). Participants also underwent an oral glucose tolerance test with measurement of plasma glucose, insulin and C-peptide concentrations to derive independent measures of insulin secretion and insulin sensitivity.
