The study was conducted to analyze the characteristic of eggs (temperature of eggshell, weight loss, and air sac alteration) at various hatching period of local duck hatched (H) and unhatched (UH) at the final observation, and to find out the effective time for estimating the life of embryo during the end of incubation. A total of 146 eggs were incubated and observed between 1 and 25 days of incubation (DOI). The results of weight loss and air sac change showed a significant difference (P<0,05) between H and UH eggs on 7 to 25 DOI, while the temperature of eggshell was only different on 25 DOI. The average characteristic of H group (temperature of eggshell, weight loss, and air sac alteration) on 25 DOI was recorded 38,46oC, 11,84%, and 51,03%, respectively. It can be concluded that 3 characteristics of eggs influence hatchability of local duck. Weight loss and air sac alteration parameters can be applyed to estimate the hatched eggs between 7 and 25 DOI, but the temperature of eggshell can be administrated after 25 DOI.

Abstract Purpose Based on recent scientific evidence, bariatric surgery is more effective in the management of morbid obesity and related comorbidities than conservative therapy. Pylorus preserving surgical procedures (PPBS) such as laparoscopic single-anastomosis duodeno-jejunal or duodeno-ileal bypass with sleeve gastrectomy are modified duodenal switch (DS) surgical techniques. The duodeno-jejunal bypass liner (DJBL) is a novel surgical method in the inventory of metabolism focused manual interventions that excludes duodeno-jejunal mucosa from digestion, mimicking DS procedures without the risk of surgical intervention. The aim of this article is to summarize and compare differences between safety-related features and weight loss outcomes of DJBL and PPBS. Methods A literature search was conducted in the PubMed database. Records of DJBL-related adverse events (AEs), occurrence of PPBS-related complications and reintervention rates were collected. Mean weight, mean body mass index (BMI), percent of excess of weight loss (EWL%), percent of total weight loss (TWL%) and BMI value alterations were recorded for weight loss outcomes. Results A total of 11 publications on DJBL and 6 publications on PPBS were included, involving 800 and 1462 patients, respectively. The baseline characteristics of the patients were matched. Comparison of DJBL-related AEs and PPBS-related severe complications showed an almost equal risk (risk difference (RD): −0.03 and confidence interval (CI): −0.27 to 0.21), despite higher rates among patients having received endoscopic treatment. Overall AE and complication rates classified by Clavien-Dindo showed that PPBS was superior to DJBL due to an excess risk level of 25% (RD: 0.25, CI: 0.01–0.49). Reintervention rates were more favourable in the PPBS group, without significant differences in risk (RD: −0.03, CI: −0.27 to 0.20). However, PPBS seemed more efficient regarding weight loss outcomes at 1-year follow-up according to raw data, while meta-analysis did not reveal any significant difference (odds ratio (OR): 1.08, CI: 0.74–1.59 for BMI changes). Conclusion Only limited conclusions can be made based on our findings. PPBS was superior to DJBL with regard to safety outcomes (GRADE IIB), which failed to support the authors’ hypothesis. Surgical procedures showed lower complication rates than the incidence of DJBL-related AEs, although it should be emphasized that the low number of PPBS-related mild to moderate complications reported could be the result of incomplete data recording from the analysed publications. Weight loss outcomes favoured bariatric surgery (GRADE IIB). As the DJBL is implanted into the upper gastrointestinal tract for 6 to 12 months, it seems a promising additional method in the inventory of metabolic interventions.

Weight loss is key to controlling the increasing prevalence of metabolic syndrome (MS) and its components, i.e., central obesity, hypertension, prediabetes and dyslipidaemia. The goals of our study were two-fold. First, we characterised the relationships between eating duration, unprocessed and processed food consumption and metabolic health. During 4 weeks of observation, 213 adults used a smartphone application to record food and drink consumption, which was annotated for food processing levels following the NOVA classification. Low consumption of unprocessed food and low physical activity showed significant associations with multiple MS components. Second, in a pragmatic randomised controlled trial, we compared the metabolic benefits of 12 h time-restricted eating (TRE) to standard dietary advice (SDA) in 54 adults with an eating duration > 14 h and at least one MS component. After 6 months, those randomised to TRE lost 1.6% of initial body weight (SD 2.9, p = 0.01), compared to the absence of weight loss with SDA (−1.1%, SD 3.5, p = 0.19). There was no significant difference in weight loss between TRE and SDA (between-group difference −0.88%, 95% confidence interval −3.1 to 1.3, p = 0.43). Our results show the potential of smartphone records to predict metabolic health and highlight that further research is needed to improve individual responses to TRE such as a shorter eating window or its actual clock time.

BACKGROUND In obesity management, whether patients lose 5% or more of their initial weight is a critical factor in their clinical outcome. However, evaluations that only take this approach cannot identify and distinguish between individuals whose weight change varies and those who steadily lose weight. Evaluation of weight loss considering the volatility of weight change through a mobile-based intervention for obesity can facilitate the understanding of individuals’ behavior and weight changes from a longitudinal perspective. OBJECTIVE With machine learning approach, we examined weight loss trajectories and explored the factors related to behavioral and app usage characteristics that induce weight loss. METHODS We used the lifelog data of 19,784 individuals who enrolled in a 16-week obesity management program on the healthcare app Noom in the US during August 8, 2013 to August 8, 2019. We performed K-means clustering with dynamic time warping to cluster the weight loss time series and inspected the quality of clusters with the total sum of distance within the clusters. To identify the usage factors to determine clustering assignment, we longitudinally compared weekly usage statistics with effect size on a weekly basis. RESULTS Initial Body Mass Index (BMI) of participants was 33.9±5.9 kg/m2, and ultimately reached an average BMI of 32.0±5.7 kg/m2. In their weight log, 5 Clusters were identified: Cluster 1 (sharp decrease) showed a high proportion of weight reduction class between 10% and 15%—the highest among the five clusters (n=2,364/12,796, 18.9%)—followed by Cluster 2 (moderate decrease), Cluster 3 (increase), Cluster 4 (yoyo), Cluster 5 (other). In comparison between cluster 2 and cluster 4, although the effect size of difference in the average meal input adherence and average weight input adherence did not show a significant difference in the first week, it increased continuously for 7 weeks (Cohen’s d=0.408; 0.38). CONCLUSIONS With machine learning approach clustering shape-based timeseries similarity, this study identified 5 weight loss trajectories in mobile weight management app. Overall adherence and early adherence related to self-monitoring emerged as a potential predictor of these trajectories.

In this study, the biodegradability and thermal properties the composites of polybutylene succinate (PBS) and chitosan of different molecular weights (Mn = 104,105, and 106 Da) were prepared at chitosan contents of 0-10 wt%. After 10 days of microbial degradation, the results show that the amount of holes from degradation was increased with either decreasing Mn or increasing chitosan contents. However, the size of holes was increased with increasing Mn and chitosan contents. The results from Differential Scanning Calorimeter (DSC) present that the melting temperature (Tm) of PBS was decreased with increasing chitosan contents. Moreover, there was no significant difference between Tm of the composites with different Mn of chitosan. From the TGA thermograms, the decomposition temperature at 10% weight loss (Td10) was decreased with increasing chitosan contents. Moreover, the water absorption of PBS/chitosan composites was increased with increasing Mn and content of chitosan.

Tyriamoji medžiaga ir metodai: Publikacijų paieška atlikta elektroninėse MEDLINE, Current Contents ir Cochrane Library duomenų bazėse. Apžvelgtos visos skrandį apjuosiančių reguliuojamų juostų lyginamųjų studijų publikacijos, paskelbtos iki 2010 m. sausio 1 d. Rezultatai: Atlikus literatūros šaltinių paiešką rasta 10 publikacijų, lyginančių skirtingas skrandį apjuosiančias reguliuojamas juostas. Išsamiai atlikta viena studija: perspektyvi, atsitiktinių imčių, jos tiriamųjų skaičius didelis ir stebėjimo laikotarpis ilgas, įvertinti visi gydymo rezultatai. Statistiškai reikšmingo skirtumo tarp SAGB ir LAP-BAND juostų šioje studijoje nerasta.

Materials and Methods: A search of articles published in any language before January 2010 was carried out through the MEDLINE, Current Contents and Cochrane Library electronic databases. All articles about comparative studies of different adjustable gastric bands were eligible for review. All possible data were extracted from accepted studies and reviewed. Results: Ten comparative studies of different adjustable gastric bands were accepted. Only one comparative study of the bands was accomplished properly. It was a prospective randomised study type with a large number of patients and a long follow-up period with all possible results evaluated. No statistically significant difference between SAGB and LAP-BAND gastric bands was found in this study. The other band studies had shortcomings: four studies were non-randomised (two of them retrospective), a small number of patients in three studies, and a too short follow-up period in all studies. The difference in weight loss was stated in one of these studies: 41.7% of initial excess weight loss in the LAP-BAND group and 28.3% in the Heliogast group. Band leakage frequency was different in one study: LAP-BAND – 7%, SAGB – 1%. A difference between pouch dilatation or band slippage frequency was found in three studies (MiniMizer Extra – 0% and LAP-BAND – 10.8%; SAGB – 2.4% and LAP-BAND – 27.6%; SAGB – 2% and LAP-BAND – 23%). There was no difference between the resolution of comorbidities, improvement of the quality of life, hospital stay, band adjustment frequency, band migration or band infection rate. Conclusion: Only one accepted study was accomplished properly. There was no difference between compared adjustable gastric bands in this study. Prospective randomised long-term (more than 5 years) comparative studies are needed for a proper evaluation of band construction or shape influence on weight loss and complications.

Background: Bariatric surgery has resulted in body weight loss, which claimed by surgery removal specific parts of the stomach with enzyme or sleeve gastrectomy. Objectives: The aim of this study is to determine weight loss and endocrine changes by 12-week fundus resection and sleeve gastrectomy in rabbits. Methods: Twenty-one rabbits, weighing 2.5 - 3.5 kg, were divided into three groups (n = 7): sleeve gastrectomy, experimental fundus resection, and sham group. The weight of rabbits and total ghrelin and leptin levels in the plasma before and after surgery were measured in 12 weeks. Statistical analyses were performed using the Kruskal-Walis test for comparison of the means between the groups, and the difference after months in one group was assayed by Friedman test. Results: The results showed sleeve gastrectomy had a significant weight loss after one month when compared to fundus resection and sham-operated controls (P = 0.008). There was no significant difference in the ghrelin levels after these surgeries, but leptin levels decreased significantly after the fundectomy (P = 0.025). Conclusions: Sleeve gastrectomy is more efficient than the fundus resection in weight loss. It could be suggested as a new option in metabolic disorders due to the high level of leptin.

Abstract Recent studies have shown that obesity is a major risk factor for idiopathic hyperaldosteronism (IHA). IHA patients have greater AGV than normal controls. However, it is unclear whether such changes are caused by obesity and whether losing weight could reverse the morphological and functional abnormalities of the adrenal gland. This study was to investigate the association of obesity with adrenal gland volume (AGV) and the effects of weight loss on AGV. This study recruited obese patients (N=25) who underwent sleeve gastrectomy and age- and sex-matched normal-weight (N=25) and overweight healthy volunteers (HV) (N=21). Thin-slice computed tomography was used to evaluate adrenal morphological changes. AGV was measured semiautomatically based on the digital imaging and communications in medicine (DICOM) image. The effects of weight loss on AGV were evaluated in patients for one year or more after sleeve gastrectomy. The results showed that left, right and total AGV were larger in obese patients than those in overweight and normal- weight HVs (6.77±0.36, 5.76±0.31, and 12.53±0.64 cm3 vs. 3.88±0.14, 3.09± 0.13 and 6.97± 0.24 cm3 vs. 3.38±0.23, 2.67±0.15 and 6.04±0.36 cm3). No statistically significant difference was identified between overweight and normal-weight HVs. Sleeve gastrectomy significantly reduced body weight (-27.1±2.5 kg), left AGV (-0.80±0.26 cm3), and right AGV (-0.88±0.20 cm2). However, the adrenal volume in five patients was not reduced, despite significant weight loss postsurgery. In brief, obesity leads to increased AGV, and in some cases, this effect seems to be irreversible. We speculate that obesity causes permanently adrenal morphological changes (increased volume or hyperplasia), and under certain circumstances, it results in excessive aldosterone secretion via altered adipokines (leptin, CTRP1, etc.).

Abstract Background Roux en Y gastric bypass (RYGB) surgery for morbid obesity is considered as gold standard, but there can be a difference in the length of alimentary and biliopancreatic limb to achieve optimum weight loss. Till now there is no agreed consensus on the ideal limb lengths and their effect on the weight loss. We would like to evaluate the change in the alimentary limb length on the weight loss after the gastric bypass surgery,  as a short to medium term single center study. Methods A retrospective analysis from prospectively maintained   database of 523 patients who underwent RYGB from  2012 till 2018 was done. Patient who had at least a follow up of 2 years(n = 388) were included.  At our center we use alimentary limb of 120 +/- 10 cm for Body Mass Index (BMI) &lt; 40 kg/m2 (group A)  and 150+/-10 cm for the BMI &gt;40 kg/m2  (Group B). The biliopancreatic limb length varies from 50 to 70 cm and this does not change with BMI.  The percentage excess weight(EWL) loss was measured and analyzed  at 1st  and 2nd year post operatively. We used paired t test to check for statistical significance. Results There were 172 patients in Group A and 216 in Group B. The number of females were 330 and  males were 58.   The average age was 44 years .  The mean  preoperative  BMI for the 120 cm limb group was  37.1 kg/m2 and  that for  150 cm limb was 45.3kg/m2. The EWL for the group A at 1 year and 2 year post op was a  Mean and standard deviation  of 79.3% +/- 39.4% and 78.3% +/- 35.2% respectively and for group B was 58.8% +/- 26.6% and 58.6% +/- 23.2% respectively. The difference was statistically significant (p &lt; 0.001) . The analysis and interpretation for metabolic syndrome is yet to be determined.   Conclusions In our study, Increasing the alimentary limb length for higher BMI reduced  EWL. This is consistent with few other publications regarding the same. This has resulted in a  change in our practice namely keeping the length of alimentary limb constant and varying the BP limb length. We will be analyzing  and presenting this data in future.

The purpose of this paper is to assess the efficacy of green coffee extract (GCE) as a weight loss supplement, using data from human clinical trials. Electronic and nonelectronic searches were conducted to identify relevant articles, with no restrictions in time or language. Two independent reviewers extracted the data and assessed the methodological quality of included studies. Five eligible trials were identified, and three of these were included. All studies were associated with a high risk of bias. The meta-analytic result reveals a significant difference in body weight in GCE compared with placebo (mean difference: kg; 95%CI: , ). The magnitude of the effect is moderate, and there is significant heterogeneity amongst the studies. It is concluded that the results from these trials are promising, but the studies are all of poor methodological quality. More rigorous trials are needed to assess the usefulness of GCE as a weight loss tool.

Abstract Aim To investigate whether preoperative malnutrition is associated with long term outcome and survival in patients undergoing radical oesophagectomy for oesophageal or oesophagogastric junction cancer. Background & Methods Dysphagia, weight loss, chemo-radiationtherapy frequently lead to malnutrition in patients with oesophageal or oesophagogastric junction cancer. Severe malnutrition is associated with higher risk of postoperative complications but little is known on the correlation with long term survival. We conducted a single center retrospective study on a prospectively collected database of patients undergoing oesophagectomy from 2008 and 2012 in order to evaluate the impact of preoperative malnutrition with postoperative outcome and long term survival. Preoperative malnutrition was classified as: prealbumin level less than 220 mg/dL (PL), MUST index (Malnutrition Universal Screeening Tool) >2 and weight loss >10%. Results 177 consecutive patients were considered: due to incomplete data 60 were excluded from the analysis that was performed on 117 patients. PL was reported in 52 (44%) patients, MUST index was recorded in 62 (53%), 58 (49%) patients presented more than 10% weight loss at the preoperative evaluation. PL was associated with more postoperative Clavien-Dindo 1-2 complications (p=0.048, OR 2.35 95%IC 1.001-5.50), no differences were observed in mortality, anastomotic leak, major pulmonary complications. MUST index was not correlated with postoperative complications nor mortality but resulted worse in patients treated with chemo-radiotherapy (p=0.046, OR 1.92 95%CI 1.011-3.64). Weight loss >10% was not associated with postoperative complications or mortality. Overall 7 years survival rate was 69%. and DFS was 68%. Malnourished patients did not differ from non-malnourished regarding age, sex, tumor site, tumor stage and histology. No significant difference in 7 years survival rates was observed in patients with PL <220 mg/dL ( 55 % vs 67%), neither in patients with MUST score>2 (58% vs 72%), nor in patients with weight loss >10% (53% vs 70%). Conclusions Malnutrition is more common in patients treated with chemoradiation therapy and it is associated with postoperative complications. However, both long term and disease free survival are not affected by preoperative nutritional status. Larger patient population and data on long term postoperative nutritional status will be analyzed in further studies.
