[Diabetology : what's new in 2024].

Diabetology is a continuously evolving discipline, many molecules are developed, and treatment recommendations change regularly according to the latest published studies. After lifestyle measures that must always be preferred before any drug, metformin remains the pharmacological basis of treatment. Current recommendations favor the introduction of an SGLT2 inhibitor or a GLP-1 receptor agonist after metformin because these molecules have shown beneficial cardiovascular and renal effects.

Linking Antibodies Against Apolipoprotein A-1 to Metabolic Dysfunction-Associated Steatohepatitis in Mice.

Metabolic dysfunction-associated fatty liver disease (MASLD) is a common liver and health issue associated with heightened cardiovascular disease (CVD) risk, with Cytokeratin 18 (CK-18) as a marker of liver injury across the MASLD to cirrhosis spectrum. Autoantibodies against apolipoprotein A-1 (AAA-1s) predict increased CVD risk, promoting atherosclerosis and liver steatosis in apoE-/- mice, though their impact on liver inflammation and fibrosis remains unclear. This study examined AAA-1s' impact on low-grade inflammation, liver steatosis, and fibrosis using a MASLD mouse model exposed to AAA-1s passive immunization (PI).

Corticosteroid therapy in older adults with cancer: Expert recommendations from a task force of the International Society of Geriatric Oncology.

Corticosteroids are used frequently in oncology and many patients require short- or long-term corticosteroid therapy. General clinical guidelines and recommendations exist on the use of corticosteroids; however, evidence is lacking for recommendations on their appropriate use in older adult with cancer. Treatment of chemotherapy-induced nausea and vomiting (CINV) has dramatically improved over the last decade with 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists and neurokinin-1 (NK-1) receptor antagonists or a combination of both.

NADPH oxidases in healthy white adipose tissue and in obesity: function, regulation, and clinical implications.

Reactive oxygen species, when produced in a controlled manner, are physiological modulators of healthy white adipose tissue (WAT) expansion and metabolic function. By contrast, unbridled production of oxidants is associated with pathological WAT expansion and the establishment of metabolic dysfunctions, most notably insulin resistance and type 2 diabetes mellitus. NADPH oxidases (NOXs) produce oxidants in an orderly fashion and are present in adipocytes and in other diverse WAT-constituent cell types.

Alterations of lipid homeostasis in morbid obese patients are partly reversed by bariatric surgery.

Besides its beneficial effect on weight loss, gastric bypass surgery (GBS) may impact the circulating levels of phospho- and sphingolipids. However, long-term effects have not been explored. To investigate alterations in lipidomic signatures associated with massive weight loss following GBS, we conducted direct infusion tandem mass spectrometry on serum and subcutaneous adipose tissue (SAT) samples collected in a longitudinal cohort of morbid obese patients prior to GBS and 1 year following the surgery.

[Diabetic gastroparesis and type 1 diabetes].

Gastroparesis is a rare and late microvascular complication, but a significant one of diabetes. Defined by a slowing of gastric emptying, this condition manifests with nonspecific gastrointestinal symptoms, including nausea, vomiting, abdominal pain, postprandial fullness, and early satiety. Faced with such a clinical presentation, it is often challenging to diagnose gastroparesis.

Langerhans cell histiocytosis of the suprasellar region: diagnosis based on thyroid cytology.

Langerhans cell histiocytosis (LCH) may present as unifocal disease of the suprasellar region, with symptoms and signs of hypopituitarism, arginine vasopressin deficiency (AVP-D), and weight gain. Transcranial biopsy is necessary to define diagnosis and guide treatment decisions, but it is associated with significant morbidity. We describe a patient with Hashimoto thyroiditis and a single hypothalamic mass in whom LCH diagnosis was made by thyroid fine-needle aspiration cytology (FNAC) performed despite nonspecific findings in thyroid imaging, on the basis of a slightly elevated [18F]-fluorodeoxyglucose (FDG) avidity on PET/CT and volume increase during follow-up.

[Obstetrics and Gynecology. Management and screening for gestational diabetes : what's new in 2023].

Gestational diabetes (GDM) is becoming increasingly common as a result of the increase in overweight, obesity and maternal age among pregnant women. As a result, in order to provide early hygienic and dietary management, it is recommended that targeted screening be carried out in the first trimester of pregnancy, based on the identification of risk factors in women. In the absence of risk factors, screening for gestational diabetes should be carried out for all pregnant women between 24 and 28 weeks' gestation.

[Diabetology: what's new in 2023].

Diabetology is a continuously evolving discipline, many molecules are developed and treatment recommendations change often according to the latest published studies. It is therefore often difficult for the primary care physician to be up to date. After lifestyle measures that must always be preferred before any drug, metformin remains the pharmacological basis of treatment.

S100A9 exerts insulin-independent antidiabetic and anti-inflammatory effects.

Type 1 diabetes mellitus (T1DM) is characterized by insulin deficiency leading to hyperglycemia and several metabolic defects. Insulin therapy remains the cornerstone of T1DM management, yet it increases the risk of life-threatening hypoglycemia and the development of major comorbidities. Here, we report an insulin signaling-independent pathway able to improve glycemic control in T1DM rodents.

Circadian organization of lipid landscape is perturbed in type 2 diabetic patients.

Lipid homeostasis in humans follows a diurnal pattern in muscle and pancreatic islets, altered upon metabolic dysregulation. We employ tandem and liquid-chromatography mass spectrometry to investigate daily regulation of lipid metabolism in subcutaneous white adipose tissue (SAT) and serum of type 2 diabetic (T2D) and non-diabetic (ND) human volunteers (n = 12). Around 8% of ≈440 lipid metabolites exhibit diurnal rhythmicity in serum and SAT from ND and T2D subjects.

Unnecessary thyroid surgery rate for suspicious nodule in the absence of molecular testing.

Background: Molecular tests for suspicious thyroid nodules decrease rates of unnecessary surgeries but are not widely used due to reimbursement issues. The aim of this study was to assess the rate of unnecessary surgery performed in real-life setting for Bethesda III, IV and V nodules in the absence of molecular testing.

Method: This is a single-center retrospective study of consecutive patients undergoing fine needle aspiration cytology (FNAC) with rapid on-site evaluation between January 2017 and December 2021.

GLP-1 receptor agonists effect on cognitive function in patients with and without type 2 diabetes.

Glucagon-like peptide 1 (GLP-1) is a hormone of the incretin family, secreted in response to nutrient ingestion, and plays a role in metabolic homeostasis. GLP-1 receptor agonist has a peripheral and a central action, including stimulation of glucose-dependent insulin secretion and insulin biosynthesis, inhibition of glucagon secretion and gastric emptying, and inhibition of food intake. Through their mechanism, their use in the treatment of type 2 diabetes has been extended to the management of obesity, and numerous trials are being conducted to assess their cardiovascular effect.

Role of Oxidative Stress and Carcinoembryonic Antigen-Related Cell Adhesion Molecule 1 in Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD) has become a widely studied subject due to its increasing prevalence and links to diseases such as type 2 diabetes and obesity. It has severe complications, including nonalcoholic steatohepatitis, cirrhosis, hepatocellular carcinoma, and portal hypertension that can lead to liver transplantation in some cases. To better prevent and treat this pathology, it is important to understand its underlying physiology.

[Non-Alcoholic Fatty Liver Disease and Diabetes: the bad marriage].

NAFLD, whose prevalence keeps growing, is strongly linked with type 2 diabetes (T2D) through insulin resistance and oxidative stress. A multifactorial association with T1D has recently been found. NAFLD screening aims to identify non-alcoholic steatohepatitis (NASH) and fibrosis and to better refer to liver specialists.

[The diabetic foot : a complex and multidisciplinary management].

Diabetic foot syndrome is a common complication in people with diabetes and peripheral sensory impairment. This complex situation requires early clinical detection by various health care professionals, but also by patients and their relatives. The clinical course, the severity of the prognosis and the management will be determined by the speed of the diagnosis.

The impact of transsphenoidal surgery on pituitary function in patients with non-functioning macroadenomas.

Purpose: Transsphenoidal surgery for non-functioning pituitary adenomas (NFPAs) can alter pituitary function. We assessed the rates of improvement and deterioration of pituitary function by axis and searched for predictive factors of these outcomes.

Methods: We reviewed consecutive medical files from patients having had transsphenoidal surgery for NFPA between 2004 and 2018.

[News in diabetology: what's new in 2022].

Diabetology is a constantly evolving discipline, many molecules appear on the market and treatment recommendations change quite frequently according to the latest published studies. It is therefore often difficult for the primary care physician to be up to date. After lifestyle measures that must of course be preferred before any drug approach, metformin remains the pharmacological basis of treatment.

Non-alcoholic fatty liver disease in type 1 diabetes: Prevalence and pathophysiology.

Non-alcoholic fatty liver disease (NAFLD) is the most frequent chronic liver disease in the general population with a global prevalence of 25%. It is often associated with metabolic syndrome and type 2 diabetes, as insulin resistance and hyperinsulinemia are known to be favoring factors. Recent studies have described growing incidence of NAFLD in type 1 diabetes (T1D) as well.
