Mosapride citrate increased gastric motility and emptying without influencing autonomic nervous activity, suggesting that it may be very useful for elderly patients or patients with autonomic imbalance.

Diabetes mellitus is a disease which must be controlled over the lifetime of a patient. We investigated the issues of stress and coping for diabetes mellitus which may influence self-management. In addition, we examined the association of these factors with blood glucose control, in order to review self-management instructions for diabetes mellitus. The study included 153 patients with diabetes mellitus. The patients were divided into two subgroups: good-control group, comprising patients with glycohemoglobin (HbA1c) values less than 7.0%; and poor-control group, comprising those with HbA1c values of 7.0% or more. All patients responded to a questionnaire regarding stress tolerance, Jalowiec and Power's coping scale and awareness of diabetes mellitus. Stress tolerance was not significantly different between the good-control and poor-control groups. No significant gender differences in coping score were evident for the good-control group. However, in the poor-control group, the coping score in men was significant higher than that in women. The problem-oriented coping score for men in the poor-control group was significantly higher than that for the good-control group (p < 0.01). In a comparison of awareness of diabetes mellitus, the proportion of patients who replied that they were rigidly following diabetes treatment was higher in the poor-control group than the good-control group. Patients with diabetes mellitus may have a knowledge of the disease and a strong will to resolve problems. This is especially true for male patients in that their will appeared to be stronger, but they may not have the resolve to establish appropriate behavior patterns. In the future, methods for evaluating self-management should be included in diabetes education.

It is suggested that the down-regulation of catecholamine may be one of the causes of postprandial hypotension in the elderly. The response to secreted catecholamine and the compensatory response to decreased blood flow in the systemic circulation were impaired in the elderly group, which finding may explain the high incidence of postprandial hypotension in the elderly subjects.

Background: Helicobacter pylori infection is involved in the formation of chronic peptic ulcer. However, a previously reported hypothesis concerning the involvement of central autonomic nervous disorder in this condition cannot be ruled out. Aim: To use spectrum analysis of heart rate viability to examine autonomic nervous activity before and after H. pylori eradication. Methods: Twenty patients with chronic duodenal ulcer (duodenal ulcer group) and 20 age‐matched normal adults (N group). In both groups, 24‐h Holter electrocardiograms (ECGs) were recorded and spectrum analysis of heartrate variability was performed. In the duodenal ulcer group, Holter ECG was recorded before and after H. pylori eradication. Results: In the N group, analysis of heart rate variability showed that high frequency (HF) power, an index of parasympathetic activity, was high at night, while the low frequency (LF)/HF ratio, an index of sympathetic function, was high during the daytime. In the duodenal ulcer group, HF power was higher at night than during the daytime, showing a similar pattern to the N group, but the power value was higher than in the N group (P < 0.05). In the duodenal ulcer group, LF/HF at night was significantly higher than that of the N group. In addition, in the duodenal ulcer group, autonomic activity after H. pylori eradication did not differ significantly from that before H. pylori eradication. Conclusions: In patients with chronic peptic ulcer, both sympatheticotonia and parasympatheticotonia may occur at night, and this abnormality in autonomic nervous activity may cause increased gastric acid secretion and gastric mucosal vasoconstriction. Abnormalities in autonomic activity persist even after H. pylori eradication, suggesting that they may be an independent risk factor in the formation of chronic peptic ulcer in addition to H. pylori infection.
