Abstract: The present disclosure is directed to impact-attenuating pathways that can be easily installed in outdoor areas, such as an outdoor area associated with a senior or assisted living facility. The impact attenuating pathways of the present disclosure provide a natural looking path having impact attenuation properties that can help prevent life threatening injuries. In addition to the impact attenuation properties, the pathway is configured to withstand regular wear from shoes, canes, crutches, and the like. The impact-attenuating pathway comprises a firm base layer, such as concrete; a cushion layer positioned on top of the base layer; and a wear layer positioned on top of the cushion layer.

Abstract: The invention provides novel methods for selecting an optimal diet and exercise regimen for a patient based on the consideration of several factors, including low density lipoprotein (LDL) and high density lipoprotein (HDL) subclass levels. Furthermore, the invention provides novel methods for treating a patient, comprising selecting an optimal diet and exercise regimen and monitoring the patient. Patients appropriate for the methods of the invention include, for example, those with cardiovascular disease (CVD) or at risk of developing CVD. In contrast to prior methods, the methods of the invention are based on the measurement of risk factors, including LDL and HDL subclass levels, that have not previously been used to select a diet and exercise regimen.
