Alpelisib is a phosphatidylinositol 3-kinase inhibitor approved by the US Food and Drug Administration for the treatment of hormone receptor-positive metastatic breast cancer with (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α) mutation. In recent years a number of adverse effects have been observed to be associated with this therapy, the most notable of which is hyperglycemia. A literature search was conducted to include case studies, case series, systematic reviews, and meta-analyses within the last 10 years that evaluated patients with mutated hormone receptor-positive, human epidermal growth factor receptor 2 negative metastatic breast cancer.

Impaired insulin secretion contributes to the pathogenesis of type 1 diabetes mellitus through autoimmune destruction of pancreatic β-cells and the pathogenesis of severe forms of type 2 diabetes mellitus through β-cell dedifferentiation and other mechanisms. Replenishment of malfunctioning β-cells via islet transplantation has the potential to induce long-term glycemic control in the body. However, this treatment option cannot widely be implemented in clinical due to healthy islet donor shortage.

Introduction: Sotalol is a beta-adrenoceptor blocking drug with unique physical and pharmacologic properties. Unlike most beta-adrenoceptor blocking drugs, sotalol is amenable to extracorporeal removal and causes QT interval prolongation and ventricular dysrhythmias. These properties have implications for treating sotalol poisoning.

Background: Patients hospitalized with moderately severe or acute severe ulcerative colitis (UC) may experience metabolic disturbances, including alterations in insulin resistance due to inflammation and the administration of glucocorticoids (GCs). This pilot study aimed to evaluate insulin sensitivity in patients hospitalized for moderately severe to severe UC.
Method: Patients hospitalized for moderately-severely active UC at Örebro University Hospital, Sweden, were eligible for inclusion.
Effects of exogenous insulin supplementation on lipid metabolism in peripartum obese dairy cows.

College of Veterinary Medicine, China Agricultural University, Beijing, China.
Cows with high body condition scores experience more severe negative energy balance (NEB) and undergo mobilization of more body fat during the peripartum period, leading to more production of nonesterified fatty acids (NEFA) and -hydroxybutyric acid (BHBA). Postpartum insulin secretion is lower, and insulin resistance is stronger in obese cows. Exogenous insulin supplementation has been hypothesized as a key approach for regulating NEFA in these cows.
