Aims: Cancer-related fatigue (CRF) is often accompanied by depressed mood, both of which reduce functional status and quality of life. Research suggests that increased expression of pro-inflammatory cytokines is associated with skeletal muscle wasting and depressive- and fatigue-like behaviors in rodents and cancer patients. We have previously shown that treatment with ibuprofen, a nonsteroidal anti-inflammatory drug, preserved muscle mass in tumor-bearing mice. Therefore, the purpose of the present study was to determine the behavioral effects of ibuprofen in a mouse model of CRF.

Main methods: Mice were injected with colon-26 adenocarcinoma cells and treated with ibuprofen (10 mg/kg) in the …

A Teaching Tool To Visually Illustrate How Manipulating The Physiology Of The Ventilatory Muscle Pump Alters Functional Performance, Dennis Sobush

Physical Therapy Faculty Research and Publications

This clinical perspective article describes an inexpensive pedagogical tool intended for use in a laboratory setting as part of a cardiovascular and pulmonary physical therapy course. It uses a dual balance scale schematic/model. As a teaching resource, physical therapy students can use it to visually reinforce their understanding of the complex cause-and-effect interplay between physiological factors that affect ventilatory muscle pump (VMP) performance for sustained breathing or contribute to VMP fatigue/failure.

Fluoxetine Prevents The Development Of Depressive-Like Behavior In A Mouse Model Of Cancer Related Fatigue, Diana M. Norden, Raymond Devine, Sabahattin Bicer, Runfeng Jing, Peter J. Reiser, Loren E. Wold, Jonathan P. Godbout, Donna O. Mccarthy

Cancer patients frequently suffer from fatigue, a complex syndrome associated with tiredness and depressed mood. Cancer-related fatigue (CRF) can be present at the time of diagnosis, escalates during treatment, and can persist for years after treatment. CRF negatively influences quality of life, limits functional independence, and is associated with decreased survival in patients with incurable disease. We have previously shown that increased pro-inflammatory cytokine expression in the brain contributes to depressive- and fatigue-like behaviors in a mouse model of CRF. Inflammatory cytokines increase the activity of indoleamine 2,3-dioxygenase (IDO) and kynurenine 3-monooxygenase (KMO), which competitively reduce serotonin synthesis. Reduced serotonin …

Tumor Growth Increases Neuroinflammation, Fatigue And Depressive-Like Behavior Prior To Alterations In Muscle Function, Diana M. Norden, Sabahattin Bicer, Yvonne Clark, Runfeng Jing, Christopher J. Henry, Loren E. Wold, Peter J. Reiser, Jonathan P. Godbout, Donna O. Mccarthy

Cancer patients frequently suffer from fatigue, a complex syndrome associated with loss of muscle mass, weakness, and depressed mood. Cancer-related fatigue (CRF) can be present at the time of diagnosis, during treatment, and persists for years after treatment. CRF negatively influences quality of life, limits functional independence, and is associated with decreased survival in patients with incurable disease. Currently there are no effective treatments to reduce CRF. The aim of this study was to use a mouse model of tumor growth and discriminate between two main components of fatigue: loss of muscle mass/function and altered mood/motivation. Here we show that …
