The need for mapping personal goals to exercise dosage in community-based exercise programs for people with Parkinson's disease.

: Community-based exercise can support long-term management of Parkinson's disease, although it is not known if personal goals are met in these programs. The objectives of this study were to: (1) examine the goals of community based exercise programs from the participant and instructor perspectives; (2) establish the extent to which these programs meet self-described exercise outcomes; and (3) explore participant and instructor perspectives on barriers to meeting exercise expectations. : This study explores the experiences of people with Parkinson's disease participating in a structured exercise program at six community sites.

Fractal analysis for classification of breast carcinoma in optical coherence tomography.

The accurate and rapid assessment of tumor margins during breast cancer resection using optical coherence tomography (OCT) has the potential to reduce patient risk. However, it is difficult to subjectively distinguish cancer from normal fibroglandular stromal tissues in OCT images, and an objective measure is needed. In this initial study, we investigate the potential of a one-dimensional fractal box-counting method for cancer classification in OCT.
