For , a ketogenic diet (KD) is a treatment option. The KD is a general term for a set of diets that contain high amounts of fat and low content of carbohydrates. The most prominent KD treatments are classical KD (41 ratio of fat to carbohydrate), modified Atkins diet (21 to 11 ratio), medium-chain triglycerides KD (with medium-chain triglyceride as a part of the fat content), and low glycemic index KD (using low glycemic carbohydrates). KD has been widely prescribed for children with epilepsy but not for adult patients. One of the main concerns about adult use of KD is its cardiovascular risk associated with high-fat and cholesterol intake. Therefore, this narrative review provides comprehensive information of the current literature on the effects of KD on lipid profile, glycemic-control biomarkers, and other cardiometabolic risk factors in adult patients with pharmacoresistant epilepsy. National guidelines advocate the use of clinical prediction models to estimate perioperative mortality for patients undergoing lung resection. Several models have been developed that may potentially be useful but contemporary external validation studies are lacking. The aim of this study was to validate existing models in a multicentre patient cohort. The Thoracoscore, Modified Thoracoscore, Eurolung, Modified Eurolung, European Society Objective Score and Brunelli models were validated using a database of 6600 patients who underwent lung resection between 2012 and 2018. Models were validated for in-hospital or 30-day mortality (depending on intended outcome of each model) and also for 90-day mortality. #link# Model calibration (calibration intercept, calibration slope, observed to expected ratio and calibration plots) and discrimination (area under receiver operating characteristic curve) were assessed as measures of model per
