“…Multiple guidelines have described several predictors of successful post-operative weight loss such as behavioral changes, pre-operative weight loss and nutrition therapy (12). Similar to other cohorts we described the tendency to increase on %TWL and %EWL in the rst year and a plateau after that time (13,14). In this study we found that baseline BMI, weight loss before surgery, nutritional follow-up and time of physical activity during the 12 months after surgery were associated with a signi cant change in %TWL and %EWL and we quanti ed the size of the impact.…”

“…Pre-operative BMI has an important effect on weight loss outcomes among patients who had bariatric surgery (13,14). Seo et al described the increase in %TWL was higher among patients treated with RYGB whose pre-operative BMI was ≥40 and it kept increasing even up to 5 years after surgery (13). Contrarily, we found that in the subgroup of patients with greater weight and BMI before surgery, the weight loss was lower at the end of follow-up, a nding that has been described in other publications (12,17).…”

Background Bariatric surgery is the most effective treatment for obesity. During long-term follow-up, weight loss (WL) is variable between subjects. The aim of this study is to assess the change in percentage of total weight loss (%TWL) and excess weight loss (%EWL) and to describe the factors associated with greater or lesser WL over time. Methods Longitudinal study including patients treated with laparoscopic Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (LSG) and followed at Hospital Universitario San Ignacio, Bogotá (Colombia). Baseline data was recorded before surgery. Follow-up was performed at 3 (n=192), 6 (n=190), 9 (n=188), 12 (n=186), 24 (n=99) and 36 (n=30) months. Generalized Estimating Equation (GEE) analysis was used to assess the change in %TWL and %EWL over time. Results 196 patients were included (82.4% female, BMI 41.3±5.2 kg/m2). The tendency to increase on %TWL (31.6±6.6) and %EWL (80.2 RIQ 70.7-97.3) was evident in the first year, stabilizing after that. Nutritionist follow-up, baseline BMI>40 kg/m2 and WL≥10kg before surgery were associated with an average higher increase of %TWL (2.39% p=0.014, 0.41% p<0.001 and 0.37% p=0.003, respectively). Subjects who performed physical activity >30 minutes/day after surgery reduced %TWL in 0.74% (p=0.009). Similar findings were described on %EWL. Conclusion Follow-up during the first year after bariatric surgery is critical to achieving %TWL and %EWL goals. This study suggests that modifiable factors such as nutritional follow-up, WL before surgery and time of physical activity are associated with a significant change in %TWL and %EWL during follow-up by a multidisciplinary team.

“…BDI-II scores), standardized pre and post-operative management and uniform surgical technique performed by a single surgeon. An inclusion criterion of at least 12 months after surgery was employed as it is shown that weight loss trajectory increases sharply in the first few months after BS, then plateaus or decreases at approximately 12 months [30].…”

Introduction/aims: Depression is the most common mental disorder found in patients seeking bariatric surgery. Current literature regarding the impact of pre-operative depression on weight outcomes after bariatric surgery is equivocal. Laparoscopic Sleeve Gastrectomy (LSG) is the most commonly performed bariatric procedure in Australia. Few studies have examined the role of depression as a predictor of weight loss post-LSG specifically. Furthermore, this relationship has not been analyzed in an Australian cohort.Methods: 124 patients underwent LSG. Pre-operative Beck Depression Inventory-II (BDI-II) scores were available for 117 patients. Post-operative weight outcomes were collected at 1 year. Univariate and multivariate analysis was performed to investigate the relationship between pre-operative BDI-II scores and weight loss outcomes at 1 year. A multivariate model was employed to examine the impact of baseline variables including age, sex and pre-operative weight on weight outcomes. Results:The mean pre-operative weight and BMI was 123.9 kg and 43.1 kg/m 2 respectively. 2 patients were lost to follow-up. The mean post-operative ΔBMI and %EWL at 12 months was 13.1 kg/m 2 and 76.1% respectively. The median pre-operative BDI-II score was 14 (range 1-52), correlating with mild depression. No significant association was found between BDI-II scores and weight outcomes on univariate and multivariate analysis. On multivariate modeling, older age resulted in lower ΔBMI (p=0.001) and TWL (p=0.001). Higher baseline weight was significantly associated with greater ΔBMI, TWL and %TWL (p=0.0). Conclusion:Pre-operative depression severity was not predictive of weight loss outcomes in this study. Future studies with standardized assessment protocols and follow-up durations are needed to delineate the impact of depression on weight loss after LSG.

“…The main inducement of obesity is not only excess food intake but also low physical activity (Xing et al , 2017). A variety of methods are used to lose weight including diet, exercise, drugs and surgical operation (Seo et al , 2017). Considering the surgical risk and the side effects caused by the drugs, most people tend to achieve and maintain a healthy weight by diet and exercise.…”

Purpose This study aims to elaborate on the microencapsulation of the plant extract (PE, from Camellia sinensis leaf, clover flower and cocoa flower) and the preparation of a slow-release lining fabric loading the PE microcapsule. Design/methodology/approach PE was microencapsulated into polyvinyl alcohol (PVA) shells through interfacial polymerization. The morphology, thermal stability, slow-release property and drug loading ratio of the PVA/PE microcapsules were characterized to ensure the availability in coating finishing. To find the optimum parameters, the composite fabrics were prepared from non-woven fabrics coated by calcium alginate hydrogel, which glued mass fractions of microcapsules and dried in different ways. To evaluate the effectiveness, a lipase enzyme activity test was conducted. Findings Under optimal conditions, the PVA/PE microcapsules with smooth surface have an average particle size of 14.5 um, and they are expected to reach a loading ratio of 38.5 per cent while remaining stable under 220°C. Given a microcapsule of 4 per cent (of the mass), the composite fabric has a good hand feeling, being prepared through calcium chloride coating. It is shown that the inhibition ratios of the microcapsules and composite fabrics on lipase are 31.3 and 21.0 per cent, respectively. Research limitations/implications The composite fabric could be prepared through the other finishing methods such as padding and printing. In addition, the release mechanism of the composite could be studied. Practical implications This study provided a simple and effective way to prolong the duration of PE. This way was conductive to protect environmental sensitive PEs from being destroyed in compositing processes. Originality/value Preparing composite fabrics for transdermal delivery system was novel and other kind of plant extracts could be used in this way.
