ABSTRACT
Recent studies have shown exercise is associated with changes in the gut microbiota in humans as well as in experimental animals. Tai Chi is an exercise that integrates a martial art, deep breathing and mediation, and has various beneficial effects for health. This review summarizes current knowledge and recent literature on the association between exercise and gut microbiota, and explores the feasibility of Tai Chi for improving gut microbiota composition and function. PubMed/MEDLINE was used to search the English literature for the keywords exercise and gut microbiota. Fourteen relevant studies were identified. In humans, exercise increases the gut microbial diversity. However, the evidence for this association is weak, as previous studies were small-scale, non-controlled studies of short duration or cross-sectional design. In animals, exercise alters the composition of gut microbiota, with some studies suggesting exercise increases the Bacteroidetes/Firmicutes ratio. However, these results are controversial, partly because host genetics and physical fitness also influence gut microbiota. Furthermore, the intensity of exercise may play a key role in how exercise affects gut microbiota. Tai Chi is a moderate-intensity exercise that improves immune function and inflammation of the gut. Tai Chi may also affect gut microbiota through vagal modulation and mediating the hypothalamic-pituitary-adrenal axis. However, no studies have investigated the association between Tai Chi and gut microbiota. Well designed studies exploring the effects of Tai Chi on gut microbiota are needed.
ABSTRACT
Objective: To develop an effective and safe therapeutic strategy, we studied the effect of the clinical characteristics of patients with acute drug intoxication on the duration of hospitalization. <br>Subjects and Methods: The subjects were 89 patients hospitalized for acute drug intoxication. They were divided into two subgroups; the short hospitalization group (duration of hospitalization < 7 days) and the long hospitalization group (duration of hospitalization ≥ 7 days). We compared age, sex, vital signs, drugs, and therapy between the two groups. <br>Results: There were no significant differences in sex or severity of consciousness disturbance between the short- and long-hospitalization groups. Age in the latter group was higher than that in the former, and age was significantly and positively correlated with the duration of hospitalization. Prolongation of hospitalization in patients with Japan Coma Scale (JCS) I or II is associated with psychiatric disease, and in patients with JCSIII, with physical disease. We used direct hemoperfusion (DHP) to treat patients with severe acute drug intoxication. The duration of hospitalization in patients treated by DHP tended to be shorter than those not so treated. <br>Conclusions: The present results suggest that aging is associated with prolongation of hospitalization and the onset of physical disease among patients with acute drug intoxication. When elderly patients with acute drug intoxication are treated in a primary-care setting, the question of whether or not physical diseases are present as complications should be considered. The appropriate use of DHP for the treatment of patients with severe acute drug intoxication requires further study.
