Medications used to treat diabetes mellitus are heterogeneous, with widely differing safety profiles in therapeutic use and in overdose. Insulin overdose may produce severe and prolonged hypoglycemia. ⋯ Glucagon-like peptide 1 agonists and dipeptidyl peptidase 4 inhibitors are benign in overdose in diabetic patients but may produce profound hypoglycemia in nondiabetic patients. Euglycemic diabetic ketoacidosis may develop in critically ill patients taking sodium-glucose co-transporter 2 inhibitors.

ReviewThe Role of Renal Functional Reserve in Predicting Acute Kidney Injury.
Renal functional reserve (RFR) is described as the difference between a glomerular filtration rate (GFR) measured at baseline and after protein stimulation. The percent change in GFR after a protein load varies based on differences in experimental conditions, with the use of an oral meat protein stimulus and a creatinine clearance method to quantify GFR showing the greatest RFR. A decline in RFR has been found in numerous patient groups. Recent investigations have suggested that a lower RFR may be associated with an increased risk of acute kidney injury and eventual chronic kidney disease.

Biomarkers have become a pillar of precision medicine in acute kidney injury (AKI). Traditional markers for diagnosis of AKI are insensitive and insufficient to provide comprehensive information for prognostication. Several emerging biomarkers have shown promising results in large-scale clinical studies. These novel markers likely will be beneficial for personalized AKI prevention and treatment.

Current advances in cancer chemotherapeutics have remarkably helped in rapid and definitive treatment options. However, these potent chemotherapeutics have been associated with severe renal toxicities that later impact treatment options. ⋯ In hospitalized patients with cancer, acute kidney injury is associated with increased morbidity, mortality, length of stay, and costs. This article provides an overview of acute kidney injury caused by cancer or its treatment, including prerenal, tubular, glomerular diseases, infiltrative disease, tumor lysis syndrome, anticancer drug nephrotoxicity, hematopoietic stem cell transplantation-related acute kidney injury, and cancer-associated thrombotic microangiopathy.

ReviewNeonatal Acute Kidney Injury: Understanding of the Impact on the Smallest Patients.
The study of neonatal acute kidney injury (AKI) has transitioned from small, single-center studies to the development of a large, multicenter cohort. The scope of research has expanded from assessment of incidence and mortality to analysis of more specific risk factors, novel urinary biomarkers, interplay between AKI and other organ systems, impact of fluid overload, and quality improvement efforts. The intensification has occurred through collaboration between the neonatology and nephrology communities. This review discusses 2 case scenarios to illustrate the clinical presentation of neonatal AKI, important risk factors, and approaches to minimize AKI events and adverse long-term outcomes.
