Intraoperative Takotsubo Syndrome.

Takotsubo cardiomyopathy is a rare condition that presents a diagnostic challenge due to its close resemblance to acute myocardial ischemia and other cardiac disorders. The excessive production of catecholamines triggers abnormal and severe changes in the myocardium, typically resulting in significant dyskinesia of the left ventricle's apex, reduced ejection fraction, hypotension, and pulmonary edema. Recent reports suggest that potential risk factors may include postmenopausal syndrome and intense, unexpected stress, whether related to life events or medical conditions.

Colitis-induced oxidative damage of the colon and skeletal muscle is ameliorated by regular exercise in rats: the anxiolytic role of exercise.

Epidemiological studies have shown that exercise protects the gastrointestinal tract, reducing the risk of diverticulosis, gastrointestinal haemorrhage and inflammatory bowel disease, while many digestive complaints occurring during exercise are attributed to the adverse effects of exercise on the colon. In order to assess the effects of regular exercise on the pathogenesis of colitis, Sprague-Dawley rats of both sexes were either kept sedentary or given exercise on a running wheel (0.4 km h(-1), 30 min for 3 days week(-1)).
