Human neutrophils by a chemiluminescence assay exhibit diminished phagocytic activity in the presence of abnormally high levels of the serum metabolite acetoacetate. These findings, along with our previous evidence demonstrating myeloperoxidase inhibition by acetoacetate, implicate metabolic ketosis in the inhibition of neutrophil microbicidal activity and thus in increased susceptibility to in...

According to the most recent National Animal Health Monitoring System for dairy cattle (National Animal Health Monitoring System, 2008), leading causes of morbidity in dairy cattle are clinical mastitis, lameness, infertility, retained placenta, milk fever, reproductive problems, and displaced abomasum. Of cows removed from herds, about 53% leave for one or more of the above reasons. Additional...

BACKGROUND Altering the macronutrient composition of the diet influences hunger and satiety. Studies have compared high- and low-protein diets, but there are few data on carbohydrate content and ketosis on motivation to eat and ad libitum intake. OBJECTIVE We aimed to compare the hunger, appetite, and weight-loss responses to a high-protein, low-carbohydrate [(LC) ketogenic] and those to a hi...

OBJECTIVE More than half of African Americans (AA) with a new diagnosis of diabetic ketoacidosis have clinical and metabolic features of type 2 diabetes during follow-up. This particular presentation of diabetes has been termed as ketosis-prone type 2 diabetes (KPDM) or atypical diabetes. METHODS We review the epidemiology, diagnosis, pathophysiology, and acute and long-term management of AA ...

BACKGROUND Ketogenic diets are high fat and low carbohydrate or very low carbohydrate diets, which render high production of ketones upon consumption known as nutritional ketosis (NK). Ketosis is also produced during fasting periods, which is known as fasting ketosis (FK). Recently, the combinations of NK and FK, as well as NK alone, have been used as resources for weight loss management and tr...
