RESUMEN
Preoperative management of patients living with severe obesity can be challenging; in this context, the preoperative weight loss may help to obtain better outcomes and less morbidity for bariatric surgery. Therefore, we evaluated the effectiveness of GLP-1 analogue Liraglutide in preoperative weight loss. We performed a single-center, quasi-experimental prospective study. Eligible participants were adults in preoperative management for bariatric-metabolic surgery with body-mass index ≥ 48 kg/m2. All patients were assigned liraglutide treatment, with an initial dose of 0.6 mg subcutaneous per day, the dose was increased each week until reaching 3.0 mg for 12 weeks. Weight loss and body composition were evaluated monthly using bioelectric impedance (BIA) (InBody 770 Scale®). We analyzed data using descriptive statistics, central tendency measures and dispersion for quantitative variables and absolute and relative frequencies for qualitative variables. A total of 37 individuals were included in this study, 28 (76%) were female and 9 (24%) were males, with an average age of 44 years. About the BMI, 19 patients (51%) had a BMI > 50 kg/m2, 10 (27%) > 40 kg/m2 and 8 (22%) > 60 kg/m2; with a total average BMI of 56.04 kg/m2. The initial weight was 147.4 ± 14.9 kg which decreased to 139.3 ± 16.8 kg; after 3 months of liraglutide administration. A total of 35 patients had some degree of weight loss (94.6%), while 2 (5.40%) had no weight changes. The total weight loss was 5.50% at 3 months of liraglutide treatment. Liraglutide could be an effective adjuvant therapy for preoperative weight loss in patients living with severe obesity.
RESUMEN
Isokinetic dynamometry is used during exercise testing and rehabilitation to obtain a quantitative strength measurement on which progressive strength training programs can be based. This study assesses the test-retest reliability of isokinetic leg function in the knee flexors and extensors at 150°/s in children and young adults with severe burns to be used for rehabilitation exercise program prescription. In 39 severely burned patients (49 ± 14% total body surface area burn [TBSA], mean ± SD; 34 ± 21% TBSA 3rd degree; 14 ± 5 years, 153.3 ± 16.5 cm height; 53.8 ± 17.9 kg) knee flexion/extension isokinetic dynamometry at 150°/s was performed on each patient's dominant leg in two sessions. The patient was acquainted with the test and performed 1 set of 10 repetitions at 150°/s. A second session of 1 set of 10 repetitions at 150°/ was performed within 24 h of the first. Muscle function outcomes were knee flexion/extension peak torque, average peak torque, and average power. One-sample paired t tests were performed for all muscle function outcomes; intraclass correlation coefficients and r2 values with session two as a function of session one were calculated. Sessions did not differ significantly in knee extension or flexion for any muscle function outcome or the hamstrings to quadriceps ratio. All intraclass correlation coefficients were >0.89 and r2 > 0.79. Test-retest isokinetic dynamometry functional measurements in the knee flexors and extensors at 150°/s are reliable in the burn population and may aid resistance rehabilitation program prescriptions.

INTRODUCTION: The increase in laparoscopic surgery in patients with obesity increases the incidence of trocar site hernia (TSH). Therefore, TSH represents a risk for the development of Richter's hernia (RH). METHODS: We present the unusual case of a postoperative gastric bypass patient complicated with a high output enterocutaneous fistula through a trocar site wound. RESULTS: The Laparoscopic surgery consists of an RH reduction, enterotomy, and repair of the preperitoneal space. CONCLUSION: RH complicated by high-output enterocutaneous fistula has not been previously reported. It is essential to close the preperitoneal space in bariatric surgery to avoid these complications.

This study tested the hypothesis that participation in a rehabilitation exercise program following hospital discharge would increase the level of physical activity in burned children than that seen in free-living nonburned children. Thirty-one severely burned children (12 ± 3 years, 144 ± 18 cm, 42 ± 17 kg, 48 ± 12% TBSA burns) were matched to 31 nonburned children (12 ± 3 y, 147 ± 17 cm, 45 ± 15 kg) based on age and sex. Pedometers were used to track minutes and steps in burned children during their exercise rehabilitation and nonburned children under free-living conditions (healthy control). We found that the average minutes of activity per day was lower in burned children (56 ± 25minutes) than in nonburned children (74 ± 28 minutes, P < .05). However, no difference was detected for average steps per day or week or maximal minutes in 1 day or week. At discharge, burn children had peak torque and mean power values that were 61% of nonburned values, and exercise training improved these by 27 and 28%, respectively (88 and 89% of nonburned values; each P ≤ .0001). Likewise, cardiorespiratory fitness at discharge was 72% of nonburned values, and exercise training improved fitness by 10% (82% of nonburned values, P < .05). Percentage TBSA burned was inversely associated with steps (r = -0.54, P = .001) and minutes of activity (r = -0.53, P = .002), accounting for 28-29% of the variability in burned children. These results show that, at discharge, burned children are capable of matching steps of physical activity levels seen in nonburned healthy children. Physical activity monitoring may be a viable option for continued improvement of physical exercise capacity when burned children are under free-living conditions.

Whether burn injury affects boys and men differently is currently unknown. To test the hypothesis that burned boys have lower exercise capacity and exercise training-induced responses compared with burned men, 40 young boys (12 ± 4 years, 149 ± 20 cm, 46 ± 18 kg) were matched to 35 adult men (33 ± 9 years, 174 ± 10 cm, 84 ± 16 kg) based on extent of burn injury (total body surface area burned, boys 46 ± 14% vs men 47 ± 30, P = .85) and length of hospital stay (boys 33 ± 23 vs men 41 ± 32 days, P = .23). Strength (peak torque) and cardiorespiratory fitness (peak VO2) were normalized to kg of lean body mass for group comparisons. Each group was also compared with normative age-sex matched values at discharge and after an aerobic and resistance exercise training (RET) program. A two-way factorial analysis of covariance assessed interaction and main effects of group and time. We found that boys and men showed similar pre-RET to post-RET increases in total lean (~4%) and fat (7%) mass (each P ≤ .008). Both groups had lower age-sex matched norm values at discharge for peak torque (boys 36%; men 51% of normative values) and peak VO2 (boys: 44; men: 59%; each P ≤ .0001). Boys strength were 13-15 per cent lower than men at discharge and after RET (main effect for group, P < .0001). Cardiorespiratory fitness improved to a greater extent in men (19%) compared with boys (10%) after the RET (group × time interaction, P = .011). These results show that at discharge and after RET, burn injury may have age-dependent effects and should be considered when evaluating efficacy and progress of the exercise program.

BACKGROUND AND OBJECTIVE: Females have a 50% increased risk of death from burn injury compared to males. However, whether exercise capacity and exercise induced training adaptations differ between burned boys and girls is unknown. This project tested the hypothesis that girls with burns have lower exercise capacity and different exercise induced training adaptations. METHODS: Twenty-five girls were matched to 26 boys (mean, 95%CI; years 13 [12,14], cm 151 [143,161], kg 54 [45,63]; each P>0.05) for burn injury (% total body surface area burn, 54 [45,62]; P=0.82). Lean body mass (LBM), strength (peak torque) and cardiorespiratory fitness (peak VO2) were normalized to kg LBM and compared as a percentage of age-sex matched non-burned children (n=26 boys, years 13 [12,14]; n=25 girls, years 13 [12,14]) at discharge (DC) and after aerobic and resistance rehabilitation exercise training (RET). RESULTS: Using a 2-way factorial ANOVA (group×time), we found both groups had similar 11% change in LBM (87.3% of non-burned values [82.2,92.3]) and after the RET (92.8% [87.2,98.3]; main effect, time P<0.0001). Peak torque increased similarly by 16% in both groups (% of age-sex matched non-burned DC, 55.9 [51.3,60.5]; after RET, 77.5 [72.1,82.9]; main effect, time P<0.0001). Likewise, peak VO2 increased in both groups by 15% (% of age-sex matched non-burned DC, 56.8 [52.4,61.2] to RET, 72.2 [67.6,76.8]; main effect, time; P<0.0001). Burned children exercise at greater percentage of their peak VO2 and peak HR compared to non-burned children (Interaction, group×time, P<0.0001). CONCLUSION: The burn injury does not have sex-dependent effects on LBM or exercise capacity in severely burn injured children. Differences in relative peak VO2 and peak HR suggest the need for burn specific exercise programs for improving the efficacy of a rehabilitation program.
