Case Report: Two Distinct Focal Congenital Hyperinsulinism Lesions Resulting From Separate Genetic Events.

Front Pediatr 2021 16;9:699129. Epub 2021 Jul 16.

Division of Endocrinology and Diabetes, Children's Hospital of Philadelphia, Philadelphia, PA, United States.

Focal hyperinsulinism (HI) comprises nearly 50% of all surgically treated HI cases and is cured if the focal lesion can be completely resected. Pre-operative localization of the lesion is thus critical. Few cases of hyperinsulinism with multiple focal lesions have been reported, and assessment of the molecular mechanisms driving this rare occurrence has been limited. Read More

Response to Comment on "Nicotinamide mononucleotide increases muscle insulin sensitivity in prediabetic women".

Science 2021 07;373(6554)

Center for Human Nutrition, Washington University School of Medicine, St. Louis, MO 63105, USA.

In evaluating any randomized clinical trial, it is important to determine whether baseline differences between groups could have affected the primary outcome. In our study, muscle insulin sensitivity, which was identical in both groups at baseline, improved after nicotinamide mononucleotide (NMN), not placebo, therapy. Differences in baseline intrahepatic triglyceride content between groups do not negate the effects of NMN observed in muscle. Read More

Advances in paediatric nonalcoholic fatty liver disease: Role of lipidomics.

World J Gastroenterol 2021 Jul;27(25):3815-3824

Department of Woman, Child, and General and Specialized Surgery, University of Campania Luigi Vanvitelli, Naples 80138, Italy.

Due its close relationship with obesity, nonalcoholic fatty liver disease (NAFLD) has become a major worldwide health issue even in childhood. The most accepted pathophysiological hypothesis is represented by the "multiple hits" theory, in which both hepatic intracellular lipid accumulation and insulin resistance mainly contribute to liver injury through several factors. Among these, lipotoxicity has gained particular attention. Read More

Hashimoto thyroiditis is characterized by anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-Tg) antibodies that gradually lead to thyroid cell destruction. As hypothyroidism has been associated with insulin resistance (IR), we aimed to investigate whether IR is associated with thyroid antibody presence and whether the degree of IR correlates with their concentration in euthyroid individuals. A total of 164 non-diabetic, euthyroid individuals, average age 34 years, were included in the study, divided into two groups according to Hashimoto thyroiditis and underwent 5-hour oral glucose tolerance test.

Insulin resistance and need for a lifestyle change to eliminate it.

Bratisl Lek Listy 2021 ;122(8):567-571

The AIM of our work is to point out the relationship between insulin resistance and metabolic compensation of diabetes mellitus, as well as to explore the possibilities of improving these parameters by non-drug measures. The rising incidence of insulin resistance associated with many comorbidities, especially due to the increase in obesity and unhealthy lifestyles, is a serious medical problem today. It is therefore necessary to be able to recognize and evaluate the presence of insulin resistance, prevent its occurrence, and ensure its elimination in high-risk individuals. Read More

Decreased Glucocorticoid Signaling Potentiates Lipid-Induced Inflammation and Contributes to Insulin Resistance in the Skeletal Muscle of Fructose-Fed Male Rats Exposed to Stress.

Int J Mol Sci 2021 Jul 4;22(13). Epub 2021 Jul 4.

Department of Biochemistry, Institute for Biological Research "Siniša Stanković"-National Institute of Re-Public of Serbia, University of Belgrade, 11000 Belgrade, Serbia.

Oleanolic Acid Targets the Gut-Liver Axis to Alleviate Metabolic Disorders and Hepatic Steatosis.

J Agric Food Chem 2021 Jul 12;69(28):7884-7897. Epub 2021 Jul 12.

College of Animal Science and Veterinary Medicine, Jinzhou Medical University, Jinzhou, Liaoning 121001, People's Republic of China.

This study investigated the effects of oleanolic acid (OA) on hepatic lipid metabolism and gut-liver axis homeostasis in an obesity-related non-alcoholic fatty liver disease (NAFLD) nutritional animal model and explored possible molecular mechanisms behind its effects. The results revealed that OA ameliorated the development of metabolic disorders, insulin resistance, and hepatic steatosis in obese rats. Meanwhile, OA restored high-fat-diet (HFD)-induced intestinal barrier dysfunction and endotoxin-mediated induction of toll-like-receptor-4-related pathways, subsequently inhibiting endotoxemia and systemic inflammation and balancing the homeostasis of the gut-liver axis.

Hypothalamic microinflammation.

Handb Clin Neurol 2021 ;181:311-322

Department of Molecular Pharmacology, Albert Einstein College of Medicine, Bronx, NY, United States.

Over the past decade, hypothalamic microinflammation has been studied and appreciated as a core mechanism involved in the advancement of metabolic syndrome and aging. Accumulating evidence suggests that atypical microinflammatory insults disturb hypothalamic regulation resulting in metabolic imbalance and aging progression, establishing a common causality for these two pathophysiologic statuses. Studies have causally linked these changes to activation of key proinflammatory pathways, especially NF-κB signaling within the hypothalamus, which leads to hypothalamic neuronal dysregulation, astrogliosis, microgliosis, and loss of adult hypothalamic neural stem/progenitor cells.

Role of Various Gene Expressions in Etiopathogenesis of Type 2 Diabetes Mellitus.

Adv Mind Body Med 2021 Summer;35(3):31-39

Context: Diabetes is a metabolic disease, with high mortality, and is characterized by increased glucose levels in the blood occurring due to poor pancreatic insulin secretion or development of insulin resistance in the body. Type 2 DM (T2DM) represents 90% of diabetic cases, and its pathogenesis involves a genetic correlation with insulin resistance, β-cell dysfunction, lifestyle, and environmental factors.

Objective: The current study intended to examine the pathophysiology of T2DM, including factors influencing insulin resistance and beta (β)-cell dysfunction as well as the genetic factors that indicate susceptibility to T2DM. Read More
