Abstract: The subject disclosure presents systems and computer-implemented methods for assessing a risk of cancer recurrence in a patient based on a holistic integration of large amounts of prognostic information for said patient into a single comparative prognostic dataset. A risk classification system may be trained using the large amounts of information from a cohort of training slides from several patients, along with survival data for said patients. For example, a machine-learning-based binary classifier in the risk classification system may be trained using a set of granular image features computed from a plurality of slides corresponding to several cancer patients whose survival information is known and input into the system. The trained classifier may be used to classify image features from one or more test patients into a low-risk or high-risk group.

Abstract: Methods to determine an individual's propensity or risk for a trait and applications thereof are described. Generally, systems and methods utilize genetic data acquired from an individual to determine their propensity or risk for a set of components that contribute to a trait. Propensity or risk of a trait is determined by assessing propensity or risk for each component of a set of components and the weighted contribution of each component to the trait.

Abstract: Methods, compositions, and devices for treating a vascular aneurysm, including an abdominal aortic aneurysm, are disclosed. In particular, the various embodiments relate to a method of treating an abdominal aortic aneurysm by increasing the mechanical stiffness of an aortic segment adjacent to the abdominal aortic aneurysm in a subject. The mechanical stiffness of the adjacent aortic segment may be increased, for example, by applying a surgical adhesive or intravascular stent. Such treatment reduces stress on the aortic wall and limits further growth of the abdominal aortic aneurysm.
