Type 2 diabetes in children and adolescents: distinct characteristics and evidence-based management.

Purpose: Since the dramatic rise of obesity prevalence in childhood and adolescence has contributed to increased rates of type 2 diabetes (T2D) in youth, we sought to explore current evidence-based management options for pediatric T2D patients.

Methods: A comprehensive literature search was performed for studies of T2D in childhood and adolescence until September 2021.

Results: Special pathophysiological and diagnostic characteristics of T2D in this age are presented, while the main focus of the article is on management.

Circulating levels of five proglucagon-derived peptides in response to intravenous or oral glucose or lipids and to a mixed-meal in subjects with normal weight, overweight, and obesity.

Aims: Proglucagon-derived peptides (PGDPs) secreted by the gut and pancreas play a major role in metabolism. We measured concentrations of five PGDPs in response to per os (PO) or intravenous (IV) glucose or lipid intake and a mixed meal test (MMT) consumed by subjects with normal weight, overweight or obesity.

Materials And Methods: GLP-1, oxyntomodulin and glicentin (gut-secreted PGDPs) and glucagon and MPGF (pancreas-secreted PGDPs) were assessed in: (a) 32 subjects receiving PO or IV glucose, lipids or water over 6 h, (b) 33 subjects with normal weight, overweight or obesity who consumed a MMT.

Interplay between baroreflex sensitivity, obesity and related cardiometabolic risk factors (Review).

The baroreflex represents a rapid negative feedback system implicated in blood pressure regulation, which aims to prevent blood pressure variations by regulating peripheral vascular tone and cardiac output. The aim of the present review was to highlight the association between baroreflex sensitivity (BRS) and obesity, including factors associated with obesity, such as metabolic syndrome, hypertension, cardiovascular disease and diabetes. For the present review, a literature search was conducted using the PubMed database until August 21, 2021.

Eligibility and Awareness Regarding Metabolic Surgery in Patients With Type 2 Diabetes Mellitus in the Real-World Clinical Setting; Estimate of Possible Diabetes Remission.

Despite high-quality evidence highlighting metabolic surgery as an effective treatment option for type 2 diabetes mellitus (T2DM), the number of patients receiving bariatric surgery (BS) remains low. Since the introduction of the Diabetes Surgery Summit II (DSS-II) eligibility criteria, data on eligibility rates for BS in T2DM cohorts remain scarce. The aims of the present study were to examine in a real-world clinical setting: (i) what is the percentage of T2DM patients visiting diabetes outpatient clinics who meet the DSS-II eligibility criteria, (ii) how many of these have been informed about the option of BS, and (iii) what are the characteristics associated with eligibility and awareness of BS.

The role of amputative and non-amputative foot deformities severity in the risk for diabetic ulceration classification systems building: a cross-sectional and case-control pilot investigation.

Introduction: Foot deformities and amputations are parameters that have been studied as risk factors for diabetic foot ulceration (DFU). However, inclusion of "foot deformities" and "amputations" in a single, broad variable and with reference to the severity of these deformities, may better characterize subjects who are prone to develop DFU.

Methods: The objective of the study was the examination of amputative and non-amputative foot deformities severity as risk factor for DFU in relation with the other established risk factors.

Postprandial Hypertriglyceridaemia Revisited in the Era of Non-Fasting Lipid Profile Testing: A 2019 Expert Panel Statement, Narrative Review.

Postprandial hypertriglyceridaemia, defined as an increase in plasma triglyceride-containing lipoproteins following a fat meal, is a potential risk predictor of atherosclerotic cardiovascular disease and other chronic diseases. Several non-modifiable factors (genetics, age, sex and menopausal status) and lifestyle factors (diet, physical activity, smoking status, obesity, alcohol and medication use) may influence postprandial hypertriglyceridaemia. This narrative review considers the studies published over the last decade that evaluated postprandial hypertriglyceridaemia.

Postprandial Hypertriglyceridaemia Revisited in the Era of Non-Fasting Lipid Profile Testing: A 2019 Expert Panel Statement, Main Text.

Residual vascular risk exists despite the aggressive lowering of Low-Density Lipoprotein Cholesterol (LDL-C). A contributor to this residual risk may be elevated fasting, or non-fasting, levels of Triglyceride (TG)-rich lipoproteins. Therefore, there is a need to establish whethe a standardised Oral Fat Tolerance Test (OFTT) can improve atherosclerotic Cardiovascular (CV) Disease (ASCVD) risk prediction in addition to a fasting or non-fasting lipid profile.

Effects of Newer Antidiabetic Drugs on Endothelial Function and Arterial Stiffness: A Systematic Review and Meta-Analysis.

Background: Newer antidiabetic drugs, i.e., dipeptidyl peptidase-4 (DPP-4) inhibitors, sodium-glucose cotransporter-2 (SGLT-2) inhibitors, and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) may exert distinct cardiovascular effects.

Follistatins in glucose regulation in healthy and obese individuals.

Aims: It has been suggested recently that follistatin (FST) and its homologous protein, follistatin-like 3 (FSTL3), may be a therapeutic target in the treatment of type 2 diabetes because of their glucose-regulatory effects in rodents.

Materials And Methods: We investigated this hypothesis in humans by studying the physiology of a possible glycaemia-follistatin feedback loop, that is, whether glucose, but not lipid intake (oral or intravenous), can regulate circulating FST and FSTL3 in healthy humans (n = 32), whether the levels of follistatins change in response to various types of bariatric operation in morbidly obese individuals, with or without type 2 diabetes (n = 41), and whether such changes are associated prospectively with improvement of glucose homeostasis/insulin sensitivity.

Results: In healthy individuals, circulating FST decreases after intravenous or oral glucose intake compared to controls, indicating the presence of a negative feedback mechanism.

Pain management of chronic wounds: Diabetic ulcers and beyond.

Patients who suffer from ulcers often experience pain of sufficient severity to reduce their quality of life. The aim of this review article is to collect, analyze and qualitatively resynthesize information regarding the definition and prevalence of ulcer pain, the pathophysiology of such pain, its assessment, and the optimal systemic and topical treatments. Early identification and prompt treatment are key to pain management.

The Effect of the Oral Administration of Leucine on Endothelial Function, Glucose and Insulin Concentrations in Healthy Subjects.

Objective: The aim of our study was to investigate the potential differential effect of hyperglycaemia and hyperinsulinaemia induced by glucose infusion alone and in combination with leucine consumption on endothelial function in healthy individuals.

Methods: Ten male volunteers were examined in random order twice. In one visit, they consumed 250 ml water (baseline) and 30 min later glucose was infused iv.

Hypertension in patients with type 2 diabetes mellitus: Targets and management.

Two-thirds of patients with type 2 diabetes mellitus (T2DM) have arterial hypertension. Hypertension increases the incidence of both micro- and macrovascular complications in these patients, while the co-existence of these two major risk factors leads to a four-fold increased risk for cardiovascular disease (CVD) compared with normotensive non-diabetic controls. The aim of this article is to comprehensively review the literature and present updated information on targets for blood pressure (BP) and on the management of hypertension in patients with T2DM.

Associations between Adiponectin Gene Variability, Proinflammatory and Angiogenetic Markers: Implications for Microvascular Disease Development in Type 2 Diabetes Mellitus?

Background: Adiponectin gene (ADIPOQ) variability may affect the risk for type 2 diabetes mellitus (T2DM) but it remains unclear whether it is involved in microvascular complications.

Objective: To explore the impact of ADIPOQ variability on markers of inflammation and angiogenesis in T2DM.

Methods: Overall, 220 consecutive T2DM patients from our outpatient diabetic clinic were genotyped for G276T (rs1501299) and T45G (rs2241766) single nucleotide polymorphisms of ADIPOQ gene.

The Real-Life Effectiveness and Care Patterns of Type 2 Diabetes Management in Greece.

Aim: To investigate the prevalence of hypoglycaemia during sulfonylurea (SU) treatment of type 2 diabetes mellitus (T2DM) in Greece and its influence on glycaemic control, treatment adherence and quality of life (QoL).

Patients And Methods: This was a retrospective cross-sectional study. We included 383 T2DM patients ≥30 years old on treatment with SU in monotherapy or in combination with metformin for at least 6 months.

Association of matrix γ-carboxyglutamic acid protein levels with insulin resistance and Lp(a) in diabetes: A cross-sectional study.

Aims: The risk of cardiovascular disease (CVD) and mortality is increased in patients with chronic kidney disease (CKD), with a background role of vascular calcification in the development of CVD also reported. Studies have demonstrated that high lipoprotein(a) (Lp(a)) levels accelerate the development of atherosclerolsis and are potentially involved in the vascular calcification. Matrix Gla Protein (MGP) seems to play an important role in vascular calcification.

Subclinical atherosclerosis in Systemic Lupus Erythematosus: Comparable risk with Diabetes Mellitus and Rheumatoid Arthritis.

Objective: Although a high risk of subclinical atherosclerosis has been reported in Systemic Lupus Erythematosus (SLE), it is not adequately compared with that observed in other rheumatic and non-rheumatic high-cardiovascular (CVD) risk diseases, such as Rheumatoid Arthritis (RA) and Diabetes Mellitus (DM). Our objective was to evaluate the relative risk (RR) of subclinical atherosclerosis in SLE, RA and DM patients compared to healthy controls, and examine potential associations with traditional and disease-related CVD risk factors in SLE.

Methods: We examined for atherosclerotic plaques 460 individuals (92% female) without CVD history, using carotid and femoral artery ultrasound: 115 SLE patients and matched 1:1 for age and gender RA, DM, and control subjects.
