Long-term efficacy of therapy in patients with fibromyalgia: a physical exercise-based program and a cognitive-behavioral approach.

Objective: To analyze the long-term efficacy of 2 interventions for female fibromyalgia (FM) patients: 1) cognitive-behavioral therapy (CBT), and 2) a physical exercise (PE)-based strategy.

Methods: We conducted a prospective, long-term, randomized, parallel clinical trial. The outcome variables are physical activity, aerobic capacity, and results of the Fibromyalgia Impact Questionnaire (FIQ), Short Form 36, Beck Anxiety and Depression Inventory, Chronic Pain Self-Efficacy Scale, and Chronic Pain Coping Inventory.

Activated epidermal growth factor receptor (ErbB1) protects the heart against stress-induced injury in mice.

Acute, high-intensity stress induces necrotic lesions in the heart. We found that restraint-and-cold (4 degrees C) exposure (RCE) raises plasma lactate dehydrogenase (LDH), creatine kinase (CK), and transaminase activity in a time-dependent manner, with a peak value 7 h after stimulus cessation. At 24 h, signs of necrotic lesions were observed in paraffin sections stained with hematoxylineosin: focal accumulation of mononuclear cells in subendocardial areas of the left ventricle wall and focal hemorrhage in papillary muscles.

Acute stress-induced tissue injury in mice: differences between emotional and social stress.

Emotional stress affects cellular integrity in many tissues including the heart. Much less is known about the effects of social stress. We studied the effect of emotional (immobilization with or without cold exposure) or social (intermale confrontation) stress in mice.
