Objective. Evaluation of early compositional changes in healing articular cartilage is critical for understanding tissue repair and for therapeutic decision-making. Fourier transform infrared imaging spectroscopy (FT-IRIS) can be used to assess the molecular composition of harvested repair tissue. Furthermore, use of an infrared fiber-optic probe (IFOP) has the potential for translation to a clinical setting to provide molecular information in situ. In the current study, we determined the feasibility of IFOP assessment of cartilage repair tissue in a rabbit model, and assessed correlations with gold-standard histology.

Design. Bilateral osteochondral defects were generated in mature white New Zealand rabbits, and …

Multidisciplinary Intensive Rehabilitation Treatment Improves Sleep Quality In Parkinson's Disease, Giuseppe Frazzitta, Roberto Maestri, Davide Ferrazzoli, Giulio Riboldazzi, Rossana Bera, Cecilia Fontanesi, Roger P. Rossi, Gianni Pezzoli, Maria Felice Ghilardi

Background Sleep disturbances are among the most common non-motor symptoms of Parkinson’s disease (PD), greatly interfering with daily activities and diminishing life quality. Pharmacological treatments have not been satisfactory because of side effects and interactions with anti-parkinsonian drugs. While studies have shown that regular exercise improves sleep quality in normal aging, there is no definitive evidence in PD.

Methods In a retrospective study, we determined whether an intense physical and multidisciplinary exercise program improves sleep quality in a large group of patients with PD.

We analyzed the scores of PD Sleep Scale (PDSS), which was administered twice, 28 days apart, …
