Review
Beyond weight loss: a review of the therapeutic uses of very-low-carbohydrate (ketogenic) diets.
Very-low-carbohydrate diets or ketogenic diets have been in use since the 1920s as a therapy for epilepsy and can, in some cases, completely remove the need for medication. From the 1960s onwards they have become widely known as one of the most common methods for obesity treatment. ⋯ This review revisits the meaning of physiological ketosis in the light of this evidence and considers possible mechanisms for the therapeutic actions of the ketogenic diet on different diseases. The present review also questions whether there are still some preconceived ideas about ketogenic diets, which may be presenting unnecessary barriers to their use as therapeutic tools in the physician's hand.

Randomized Controlled Trial
Preoperative immunonutrition and its effect on postoperative outcomes in well-nourished and malnourished gastrointestinal surgery patients: a randomised controlled trial.
Invasive procedures such as surgery cause immunosuppression, leading to increased risk of complications, infections and extended hospital stay. Emerging research around immune-enhancing nutrition supplements and their ability to reduce postoperative complications and reduce treatment costs is promising. This randomised controlled trial aims to examine the effect of preoperative immunonutrition supplementation on length of hospital stay (LOS), complications and treatment costs in both well-nourished and malnourished gastrointestinal surgery patients. ⋯ Preoperative immunonutrition therapy in gastrointestinal surgery has the potential to reduce the LOS and cost, with greater treatment benefit seen in malnourished patients; however, there is a need for additional research with greater patient numbers.
