Metabolic risk factor targets in relation to clinical characteristics and comorbidities among individuals with type 2 diabetes treated in primary care - The countrywide cross-sectional AUSTRO-PROFIT study.

Aims: This study assessed the achievement rates of metabolic risk factor targets and their association with clinical characteristics and comorbidities among individuals with type 2 diabetes (T2D) treated in the primary care in Austria.

Materials And Methods: A countrywide cross-sectional study, the AUSTRO-PROFIT, was conducted in Austria from 2021 to 2023 on 635 individuals with T2D. Metabolic risk factor targets were defined as the percentage of people achieving low-density lipoprotein cholesterol (LDL-C) <70 mg/dL (or < 55 mg/dL if cardiovascular or microvascular disease was present), glycated haemoglobin (HbA1c) <7% (53 mmol/mol) and blood pressure < 140/90 mmHg.

[Prevention and management of postinterventional weight regain].

Decreasing levels of patient motivation or compliance are far from being the only causes of postinterventional weight regain after lifestyle, psychological, pharmacological and surgical interventions. Weight regain originates from a complex and individually varying set of central and peripheral mechanisms, with the overall purpose of increasing food intake by both stimulating hunger and reducing satiety (mediated by gastrointestinal hormones) and decreasing the body's energy demands (via metabolic adaption). These mechanisms counteract any attempts to reduce or maintain body weight in today's increasingly prevalent adipogenic environments.

[Overweight and obesity in adults: general principles of treatment and conservative management].

The prevalence of overweight and obesity is steadily increasing in Austria as well as internationally. Obesity in particular is associated with multiple health risks, comorbidities, functional disability, and social stigma. Obesity is an independent, complex, chronic disease and should be treated as such by a multidisciplinary team of appropriately qualified personnel.

Alterations of hepatic energy metabolism in murine models of obesity, diabetes and fatty liver diseases.

Background: Disturbed hepatic energy metabolism contributes to non-alcoholic fatty liver (NAFLD), but the development of changes over time and obesity- or diabetes-related mechanisms remained unclear.

Methods: Two-day old male C57BL/6j mice received streptozotocin (STZ) or placebo (PLC) and then high-fat (HFD) or regular chow diet (RCD) from week 4 (W4) to either W8 or W16, yielding control [CTRL = PLC + RCD], diabetes [DIAB = STZ + RCD], obesity [OBES = PLC + HFD] and diabetes-related non-alcoholic steatohepatitis [NASH = STZ + HFD] models. Mitochondrial respiration was measured by high-resolution respirometry and insulin-sensitive glucose metabolism by hyperinsulinemic-euglycemic clamps with stable isotope dilution.

[Hospital diabetes management (Update 2023)].

This position statement presents the recommendations of the Austrian Diabetes Association for diabetes management of adult patients during inpatient stay. It is based on the current evidence with respect to blood glucose targets, insulin therapy and treatment with oral/injectable antidiabetic drugs during inpatient hospitalization. Additionally, special circumstances such as intravenous insulin therapy, concomitant therapy with glucocorticoids and use of diabetes technology during hospitalization are discussed.

[Antihyperglycemic treatment guidelines for diabetes mellitus type 2 (Update 2023)].

Hyperglycemia significantly contributes to complications in patients with diabetes mellitus. While lifestyle interventions remain cornerstones of disease prevention and treatment, most patients with type 2 diabetes will eventually require pharmacotherapy for glycemic control. The definition of individual targets regarding optimal therapeutic efficacy and safety as well as cardiovascular effects is of great importance.

[Other specific types of diabetes and exocrine pancreatic insufficiency (update 2023)].

The heterogenous category "specific types of diabetes due to other causes" encompasses disturbances in glucose metabolism due to other endocrine disorders such as acromegaly or hypercortisolism, drug-induced diabetes (e.g. antipsychotic medications, glucocorticoids, immunosuppressive agents, highly active antiretroviral therapy (HAART), checkpoint inhibitors), genetic forms of diabetes (e.

Empagliflozin protects mice against diet-induced obesity, insulin resistance and hepatic steatosis.

Aims/hypothesis: Sodium-glucose cotransporter 2 (SGLT2) inhibitors are widely used in the treatment of type 2 diabetes, heart failure and chronic kidney disease. Their role in the prevention of diet-induced metabolic deteriorations, such as obesity, insulin resistance and fatty liver disease, has not been defined yet. In this study we set out to test whether empagliflozin prevents weight gain and metabolic dysfunction in a mouse model of diet-induced obesity and insulin resistance.

Biomarkers Predictive for In-Hospital Mortality in Patients with Diabetes Mellitus and Prediabetes Hospitalized for COVID-19 in Austria: An Analysis of COVID-19 in Diabetes Registry.

Background: This study assessed the predictive performance of inflammatory, hepatic, coagulation, and cardiac biomarkers in patients with prediabetes and diabetes mellitus hospitalized for COVID-19 in Austria.

Methods: This was an analysis of a multicenter cohort study of 747 patients with diabetes mellitus or prediabetes hospitalized for COVID-19 in 11 hospitals in Austria. The primary outcome of this study was in-hospital mortality.

Changing the dietary composition improves inflammation but not adipocyte thermogenesis in diet-induced obese mice.

Pronounced weight loss was shown to improve adipocyte dysfunction and insulin sensitivity in obese subjects. While bariatric surgery is frequently accompanied by adverse side effects, weight loss due to caloric restriction is often followed by weight regain. Here we aimed to determine whether switching the diet from a metabolically harmful Western type diet to a balanced standard diet is sufficient to reverse adipocyte dysfunction in diet-induced obese mice.

Apolipoprotein A5 controls fructose-induced metabolic dysregulation in mice.

Background And Aims: Western dietary habits are partially characterized by increased uptake of fructose, which contributes to metabolic dysregulation and associated liver diseases. For example, a diet enriched with fructose drives insulin resistance and non-alcoholic fatty liver disease (NAFLD). The molecular hubs that control fructose-induced metabolic dysregulation are poorly understood.

COVID-19 fatality prediction in people with diabetes and prediabetes using a simple score upon hospital admission.

Aim: To assess predictors of in-hospital mortality in people with prediabetes and diabetes hospitalized for COVID-19 infection and to develop a risk score for identifying those at the greatest risk of a fatal outcome.

Materials And Methods: A combined prospective and retrospective, multicentre, cohort study was conducted at 10 sites in Austria in 247 people with diabetes or newly diagnosed prediabetes who were hospitalized with COVID-19. The primary outcome was in-hospital mortality and the predictor variables upon admission included clinical data, co-morbidities of diabetes or laboratory data.

Cardioprotective effects of short-term empagliflozin treatment in db/db mice.

Sodium glucose transporter (SGLT)-2 inhibitors have consistently shown cardioprotective effects independent of the glycemic status of treated patients. In this study we aimed to investigate underlying mechanisms of short-term empagliflozin treatment in a mouse model of type II diabetes. Male db/db mice were fed a western type diet with or without enrichment with empagliflozin for 7 days.

Metabolic effects of reduced growth hormone action in fatty liver disease.

Background: Adult growth hormone (GH) deficiency is associated with fatty liver disease and shows several features of the metabolic syndrome. Vice versa obesity is characterized as a state of low GH function. Here, we aimed to define the role of hepatic GH signaling and its metabolic consequences in non-alcoholic fatty liver disease.

Circulating Wnt inhibitory factor 1 levels are associated with development of cardiovascular disease.

Background And Aims: Wnt signaling is involved in atherosclerotic plaque formation directly and indirectly by modulating cardiovascular risk factors. We investigated whether circulating concentrations of Wnt inhibitors are associated with cardiovascular events in subjects with intermediate cardiovascular risk.

Methods: 904 non-diabetic subjects participating in the SAPHIR study were assessed.

Fat-enriched rather than high-fructose diets promote whitening of adipose tissue in a sex-dependent manner.

Adipose tissue is a critical regulator of energy metabolism and an effector organ of excessive caloric intake. We studied the effects of high-fructose (HFruD), high-fat (HFD) and mixed high-sucrose and high-fat diet (HFHSD) on adipocyte morphology and biology and consecutive metabolic effects in male and female C57BL/6 mice. Forty male and 40 female mice were randomly assigned to one of four dietary groups and fed for 10 weeks ad libitum.

Dipeptidyl peptidase-4 impairs insulin signaling and promotes lipid accumulation in hepatocytes.

Dipeptidyl-peptidase 4 [DPP-4) has evolved into an important target in diabetes therapy due to its role in incretin hormone metabolism. In contrast to its systemic effects, cellular functions of membranous DPP-4 are less clear. Here we studied the role of DPP-4 in hepatic energy metabolism.

Mechanisms of intrahepatic triglyceride accumulation.

Hepatic steatosis defined as lipid accumulation in hepatocytes is very frequently found in adults and obese adolescents in the Western World. Etiologically, obesity and associated insulin resistance or excess alcohol intake are the most frequent causes of hepatic steatosis. However, steatosis also often occurs with chronic hepatitis C virus (HCV) infection and is also found in rare but potentially life-threatening liver diseases of pregnancy.

Incidence of Gallstone Formation and Cholecystectomy 10 Years After Bariatric Surgery.

Purpose: Rapid weight loss is a risk factor for gallstone formation, and postoperative treatment options for gallstone formation are still part of scientific discussion. No prospective studies monitored the incidence for gallstone formation and subsequent cholecystectomy after bariatric surgery longer than 5 years. The aim of the study was to determine the incidence of gallstone formation and cholecystectomy in bariatric patients over 10 years.

The effects of psychotropic drugs on the regulation of glucose metabolism.

Psychotropic drugs, like antipsychotics and antidepressants, are often associated with metabolic side effects such as weight gain and an increased risk of the development of diabetes and an atherogenic lipid profile. These adverse effects not only bear a high cardiovascular risk and lead to higher morbidity and mortality, but are an additional burden to mentally ill patients and can be a decisive factor for the compliance and, consequently, the success of the therapy. Second generation antipsychotics (SGAs), in particular, clozapine and olanzapine, lead to significant weight gain and impair glucose metabolism.

Body adiposity index and other indexes of body composition in the SAPHIR study: association with cardiovascular risk factors.

Objective: The accuracy of anthropometric surrogate markers such as the body adiposity index (BAI) and other common indexes like the body mass index (BMI), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) to predict metabolic sequelae is essential for its use in clinical practice.

Design And Methods: Thus, we evaluated the strength of BAI and other indexes to relate with anthropometric parameters, adipocytokines, blood lipids, parameters of glucose-homeostasis and blood pressure in 1,770 patients from the Salzburg Atherosclerosis Prevention Program in Subjects at High Individual Risk (SAPHIR) study in a crosssectional design. Measurements were BAI, BMI, WHR, WHtR, abdominal subcutaneous and visceral adipose tissue (aSAT and VAT), total body adipose tissue mass, body weight, waist- and hip circumference (WC and HC), leptin, adiponectin, high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), triglycerides (TG), fasting plasma glucose, fasting plasma insulin, the homeostasis model assessment of insulin resistance (HOMAIR), systolic and diastolic blood pressure.

High-fat diet causes iron deficiency via hepcidin-independent reduction of duodenal iron absorption.

Obesity is often associated with disorders of iron homeostasis; however, the underlying mechanisms are not fully understood. Hepcidin is a key regulator of iron metabolism and may be responsible for obesity-driven iron deficiency. Herein, we used an animal model of diet-induced obesity to study high-fat-diet-induced changes in iron homeostasis.

[Psychotropic drugs and diabetes].

Psychotropic drugs, such as antipsychotics and antidepressants, are widely used substances which can display marked metabolic side effects. Psychiatric patients display increased morbidity and mortality which, besides disease specific factors, may be attributed to metabolic side effects of psychotropic drugs. Commonly observed side effects of antipsychotics are weight gain as well as disturbances in glucose and lipid metabolism.

Effect of weight loss on serum pigment epithelium-derived factor levels.

Background: Cumulating evidence suggests that the broadly acting neurotrophic pigment epithelium-derived factor is associated with visceral adiposity, the metabolic syndrome, diabetes and exerts beneficial effects on atherosclerosis. To further elucidate the relationship between pigment epithelium-derived factor and metabolic perturbations characteristic of obesity, we examined the effect of pronounced weight loss on serum levels of pigment epithelium-derived factor.

Materials And Methods: Thirty-six severely obese adults were examined before and 18 months after bariatric surgery.
