Background

Between 2 and 8 weeks before surgery, most bariatric surgery groups establish strict dietary treatments with a total caloric intake of less than 1,000 kcal/day in order to maximize weight loss during this period of time.

Methods

A prospective randomized clinical trial of all the patients undergoing laparoscopic sleeve gastrectomy (LSG) was performed. Patients were randomly assigned into 3 groups: those patients receiving a preoperative regular diet of 900 kcal/day (group 1), those receiving a preoperative balanced energy high-protein formula (group 2) and those receiving preoperative Immunonutrition (group 3). Preoperative weight loss, postoperative pain, complications and analytical acute phase reactants were investigated.

Results

Sixty patients were included in the study, 20 in each group. Preoperative excess weight loss was 7.7 % in group 1, 12.3 % in group 2 and 15.3 % in group 3 (p?=?0.014). Median postoperative pain was 3.5 in group 1, 3 in group 2 and 2 in group 3 (p?=?0.048). C-reactive protein determined 24 h after surgery was significantly lower in group 3 than in the other groups. AST and ALT values were significantly lower in group 3 than in the other groups, without significant differences between groups 1 and 2.

Conclusions

Preoperative diet with Immunonutrition formulas during 2 weeks achieves a greater preoperative weight loss, lower postoperative pain and lower values of CRP and liver enzymes than high-protein formulas or regular diet, all of them with similar caloric intake.

Pulmonary rehabilitation (PR) has been shown to improve dyspnea, exercise capacity and health-related quality of life in patients with chronic obstructive pulmonary disease (COPD). PR has also shown benefits in diseases other than COPD but the level of evidence is lower. The fundamental components of PR programs are muscle training, education and chest physiotherapy. Occupational therapy, psychosocial support and nutritional intervention should also be considered. Home programs have been shown to be as effective as hospital therapy. The duration of rehabilitation programs should not be less than 8 weeks or 20 sessions. Early initiation of PR, even during exacerbations, has proven safe and effective. The use of oxygen or noninvasive ventilation during training is controversial and dependent on the patient's situation. At present, the best strategy for maintaining the benefits of PR in the long term is unknown. Longer PR programs or telemedicine could play a key role in extending the results obtained.  相似文献

After reviewing our experience with pollicization in congenital cases of thumb hypoplasia or aplasia, we found that classic techniques have several weak points concerning function and appearance. Abduction is frequently inadequate, and adduction is quite weak. Esthetically the thumb has a slender aspect, the web fold is absent, and the commissure looks more like a cleft. We tried to prioritize the issues to propose some technical modifications for improvement of function and appearance.  相似文献
