Towards safe and reliable deep learning for lung nodule malignancy estimation using out-of-distribution detection.

Artificial Intelligence (AI) models may fail or suffer from reduced performance when applied to unseen data that differs from the training data distribution, referred to as dataset shift. Automatic detection of out-of-distribution (OOD) data contributes to safe and reliable clinical implementation of AI models. In this study, we propose a recognized OOD detection method that utilizes the Mahalanobis distance (MD) and compare its performance to widely known classical methods.

Rationale and design of the STOP-IMH randomised trial: Safety of ticagrelor monotherapy after primary percutaneous coronary intervention for ST-elevation myocardial infarction and the effect on intramyocardial haemorrhage.

Background: Ticagrelor monotherapy after 1-3 months of dual antiplatelet therapy (DAPT) has shown to be effective and safe after percutaneous coronary intervention (PCI), including in patients with an ST elevation myocardial infarction (STEMI). Direct omission of aspirin could further reduce bleeding complications and may reduce the incidence and expansion of intramyocardial haemorrhage (IMH), a frequent complication after revascularisation for a STEMI.

Methods: This multicentre open label pilot study randomises 200 STEMI patients within 24 hours after primary PCI and before the first subsequent dose of aspirin to ticagrelor monotherapy or ticagrelor plus aspirin for twelve months.

Extradigital Glomus Tumor at the Elbow.

Extradigital glomus tumor should be considered in the differential diagnosis of a highly vascular solid lesion that is painful on palpation.

Fasting triglyceride concentrations are associated with markers of lipid metabolism and glucose homeostasis in healthy, non-obese dogs in lean and overweight condition.

Serum triglyceride concentrations increase in dogs with obesity, which is typically assessed by body condition score (BCS), however little is known about changes that take place in non-obese dogs in overweight condition. Further, the associations of triglyceride levels with other markers of energy homeostasis are poorly characterised in healthy animals. The present study aimed to evaluate associations between both BCS and triglyceride concentrations with other markers of lipid and glucose metabolism in healthy, non-obese dogs, as well as to assess whether these markers change significantly in non-obese dogs with overweight as compared to their lean counterparts.
