Perfusion network shift during seizures in medial temporal lobe epilepsy.

Background: Medial temporal lobe epilepsy (MTLE) is associated with limbic atrophy involving the hippocampus, peri-hippocampal and extra-temporal structures. While MTLE is related to static structural limbic compromise, it is unknown whether the limbic system undergoes dynamic regional perfusion network alterations during seizures. In this study, we aimed to investigate state specific (i.

Cognitive impairment is associated with reduced bone mass in multiple sclerosis.

Background: Multiple sclerosis (MS) has been associated with reduced bone mineral density (BMD), yet the underlying causes are not fully known. The recent discovery that bone homeostasis is directly regulated by the brain led us to hypothesize that it may be impaired by MS pathology. As cognitive impairment (CI) is a well-documented correlate of MS-related brain pathology, we tested the hypothesis that it is associated with reduced BMD.

Development of communities of practice to facilitate quality improvement initiatives in surgical oncology.

Background: The process of developing clinical guidelines and standards for cancer treatment and screening is well established in the Ontario health care system; however, the dissemination and implementation of such guidelines and standards are more recent undertakings. Traditional implementation strategies to improve surgical practice and the delivery of cancer care have not been consistently effective. There is a recognized need to develop integrated models that offer direct support for implementation strategies.
