[From the discovery of incretin hormones to GIP / GLP-1 / glucagon double and triple agonists].

The concept of treating diabetes with gut hormones was proposed in the early days of endocrinology (1902), but was not put into practice until the early 2000s. The discovery of the incretin effect (potentiation of insulin secretion when glucose is taken orally compared to intravenously) led to the discovery of the two main gut hormones responsible for this effect: GIP and GLP-1. The reduction of the incretin effect is directly involved in the pathogenesis of type 2 diabetes, which has led to the development of a series of innovative therapies such as GLP-1 analogues, GLP-1 receptor agonists, GIP/GLP-1 co-agonists and GIP/GLP-1/glucagon tri-agonists.

Medial arterial calcification of the lower limbs in diabetes: Time for awareness? A short narrative review.

In patients with diabetes, peripheral arterial disease, particularly below the knee, is associated with medial arterial calcification. This is a frequent and potentially serious complication, affecting all types of diabetes. In recent years, our understanding of the pathophysiology and clinical significance of medial arterial calcification has improved considerably.

ZEBRA study: The Z stitch Early Bed Rest Assessment study.

Background: Safe and effective management of venous vascular access is a key component of electrophysiology (EP) procedures. Recently, the Z-stitch method has been developed for effective venous hemostasis. However, the standard postprocedure protocol often includes prolonged bed rest, which may affect patient satisfaction.

Out with the old: Single center experience with transvenous extraction of leads older than 15 years.

Background: Lead dwell time is the single strongest predictor of failure and complications in transvenous lead extraction.

Objectives: To report the success rate and complications of transvenous lead extractions with implant dwell time of at least 15 years.

Methods: Procedural and patient data were prospectively collected into a database.

Impact of fixation mechanism and helix retraction status on right ventricular lead extraction.

Background: The impact of lead fixation mechanism on extractability is poorly characterized.

Objective: We aimed to compare the technical difficulty of transvenous lead extraction (TLE) of active vs passive fixation right ventricular (RV) leads.

Methods: A total of 408 patients who underwent RV TLE by a single expert electrophysiologist at Oregon Health & Science University between October 2011 and June 2022 were identified and retrospectively analyzed; 331 (81%) had active fixation RV leads and 77 (19%) had passive fixation RV leads.

Interactions between diabetes and COVID-19: A narrative review.

Diabetes, whether due to pancreatic beta cells insufficiency or peripheral resistance to insulin, has been suggested as a risk factor of developing severe acute respiratory disease coronavirus-2 (SARS-CoV-2) infections. Indeed, diabetes has been associated with a higher risk of infections and higher risk of developing severe forms of coronavirus disease 2019 (COVID-19) related pneumonia. Diabetic patients often present associated comorbidities such as obesity, hypertension and cardiovascular diseases, and complications of diabetes, including chronic kidney disease, vasculopathy and relative immune dysfunction, all of which make them more susceptible to infectious complications.

SREBP-1c and lipogenesis in the liver: an update1.

Sterol Regulatory Element Binding Protein-1c is a transcription factor that controls the synthesis of lipids from glucose in the liver, a process which is of utmost importance for the storage of energy. Discovered in the early nineties by B. Spiegelman and by M.

Cardiac adipose tissue volume and IL-6 level at admission are complementary predictors of severity and short-term mortality in COVID-19 diabetic patients.

Background: COVID-19 diabetic adults are at increased risk of severe forms irrespective of obesity. In patients with type-II diabetes, fat distribution is characterized by visceral and ectopic adipose tissues expansion, resulting in systemic inflammation, which may play a role in driving the COVID-19 cytokine storm. Our aim was to determine if cardiac adipose tissue, combined to interleukin-6 levels, could predict adverse short-term outcomes, death and ICU requirement, in COVID-19 diabetic patients during the 21 days after admission.

mutations cause a lipoatrophic diabetes syndrome due to impaired epoxide hydrolysis and increased cellular senescence.

Epoxide hydrolases (EHs) regulate cellular homeostasis through hydrolysis of epoxides to less-reactive diols. The first discovered EH was EPHX1, also known as mEH. EH functions remain partly unknown, and no pathogenic variants have been reported in humans.

Does Sex Modify an Association of Electrophysiological Substrate with Sudden Cardiac Death? The Atherosclerosis Risk in Communities (ARIC) Study.

Background—: Sex is a well-recognized risk factor for sudden cardiac death (SCD). We hypothesized that sex modifies the association of electrophysiological (EP) substrate with SCD.

Methods—: Participants from the Atherosclerosis Risk in Communities study with analyzable ECGs (n=14,725; age, 54.

Impaired hypoxic ventilatory drive induced by diabetic autonomic neuropathy, a cause of misdiagnosed severe cardiac events: brief report of two cases.

Background: Sudden cardiac deaths are twice more frequent in diabetic patients with cardiac autonomic neuropathy. Sudden cardiac death etiologies remain unclear and no recommendations are made to identify factors associated with cardiorespiratory arrest in diabetic patients. We hypothesized, from two clinical cases, that impaired hypoxic ventilatory drive, induced by diabetic autonomic neuropathy, is a cause of misdiagnosed severe cardiac events.

Dihydroceramides in Triglyceride-Enriched VLDL Are Associated with Nonalcoholic Fatty Liver Disease Severity in Type 2 Diabetes.

Plasma dihydroceramides are predictors of type 2 diabetes and related to metabolic dysfunctions, but the underlying mechanisms are not characterized. We compare the relationships between plasma dihydroceramides and biochemical and hepatic parameters in two cohorts of diabetic patients. Hepatic steatosis, steatohepatitis, and fibrosis are assessed by their plasma biomarkers.
