スクワットの効果的トレーニング : 糖尿病に対するハイスクワットの試行

Background: Recent clinical problems in primary care medicine include metabolic syndrome (Met-S) as well as other problems, such as diabetes mellitus, locomotive syndrome (Loc-S) and flailty in middle-age to older people. Regarding exercise therapy for patients with Met-S and Loc-S, aerobic exercise and also resistance (anaerobic) exercise have been considered as necessary. Thus, simple and effective resistance exercise methods should be clarified. Subjects and Methods: The subjects were 61 patients (male 36, female 25) with diabetes mellitus (66.9 ± 13.5 years old, mean ± SD). Subjects were instructed to perform a continuous squat exercises 5 minutes in morning and evening every day for 6 months, using the small exercise equipment ‘HiSquat”. The movements included 1) walking or jogging, 2) inner thigh exercise, 3) outer thigh exercise, 4) straight thigh exercise. Parameters were height, body weight, body mass index (BMI), abdominal circumference, thigh circumference and blood HbA1c value. The treatment of the subjects were not changed during the 6 months. HbA1c value was compared between 0 and 6 months. Results: The fundamental data before the study were as follows: height 159.4 ± 8.4 cm, body weight 62.5 ± 13.8 kg, BMI 24.5 ± 4.7 kg/m2, abdominal circumference 86.8 ± 10.7 cm, thigh circumference 42.9 ± 6.4 cm, HbA1c 6.8 ± 0.9%. HbA1c value at 6 months was 6.4 ± 1.0%, with a statistically significant decrease of 0.4%. As for the correlation analyses, a positive significant correlation was observed between BMI and the thigh/height ratio, and a negative significant correlation was observed between age and thigh/waist ratio. Conclusion: In this study, the HbA1c value was significantly decreased, which suggests the exercise effect of HiSquat. Our study provides fundamental data for the value of waist/thigh circumference in the exercise therapy, and also the efficacy of HiSquat; consequently it suggests the efficacy of HiSquat use for Met-S, Loc-S and flailty, which are increasing concerns in anti-aging medicine of Japan

Clinical characteristics and course of sporadic non-ampullary duodenal adenomas A multicenter retrospective study

Sporadic non-ampullary duodenal adenoma (SNADA) is a rare disease, and therefore, its clinical characteristics have not been comprehensively investigated. Furthermore, owing to the high complication rates and severity of endoscopic resection, treatment strategies vary among facilities. In the present study, we aimed to clarify the clinical characteristics and course of SNADA. We extracted clinical and histological records of SNADA cases diagnosed in 11 hospitals between September 1999 and August 2014. The patients were divided into "no-resection" and "resection" groups based on the initial treatment approach. We investigated the long-term outcome of the "no-resection" group and treatment results of the "resection" group, with particular interest in endoscopic resection. Overall, 299 patients were diagnosed with SNADA. The median age at diagnosis was 67 years (range, 31-88 years), with approximately twice as many men as women. The median tumor size was 8.0 mm (2-60 mm). In total, 161 patients were initially selected for no-resection and 138 underwent resection. Age >70 years and the presence of either severe illness or poor performance status were significantly related to opting for no-resection. In the no-resection group, 101 patients underwent endoscopic follow-up for at least 1 year. During the observational period (2.5 +/- 2.2 years), 27 lesions (27%) disappeared following cold forceps biopsy, and 13 lesions (14%) presented lateral growth. Four lesions (4%) changed to mucosal carcinoma, 3 were treated endoscopically, and 1 was surgically resected. Nineteen patients died; however, no one died of duodenal carcinoma. In the endoscopic resection group, en bloc resection was achieved in 78% of patients. However, the complication rate for perforation was 7%, and endoscopic submucosal dissection was associated with a 36% perforation rate. With the low incidence of cancer development and no disease specific death, the strategy of initially not performing resection could be considered especially for the older adults, poor-prognosis patients, or small lesions
