Abstract

Obese patients are frequently characterized by insulin resistance and decreased insulin-mediated glycogen synthesis in skeletal muscle. Whether they also have impaired postprandial hepatic glycogen synthesis remains unknown. To determine whether postprandial hepatic glycogen synthesis is decreased in obese patients compared to lean subjects. Lean and obese subjects with impaired glucose tolerance were studied over 4h after ingestion of a glucose load. Hepatic uridine diphosphoglucose kinetics were assessed using 13C-galactose infusion, with monitoring of urinary acetaminophen-glucuronide isotopic enrichment to estimate hepatic glycogen kinetics. Estimated net hepatic glycogen synthesis amounted to 18.6 and 22.6% of the ingested load in lean and obese subjects, respectively. Postprandial hepatic glycogen metabolism is not impaired in non-diabetic obese subjects.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
