Salt taste after bariatric surgery and weight loss in obese persons

Background.Little is known about the perception of salty taste in obese patients, especially after bariatric surgery. Therefore, the aim of this study was to analyse possible differences in salt detection thresholds and preferences for foods differing in salt content in obese persons before and after bariatric surgery with weight loss compared to non-obese individuals.Methods.Sodium chloride detection thresholds and liking for cream soups with different salt concentrations were studied with established tests. Moreover, a brief salt food questionnaire was assessed to identify the usage and awareness of salt in food.Results.The results showed similar mean sodium chloride detection thresholds between non-obese and obese participants. After bariatric surgery a non-significant increase in the salt detection threshold was observed in the obese patients (mean ± SD: 0.44 ± 0.24 g NaCl/L before OP vs. 0.64 ± 0.47 g NaCl/L after OP,p= 0.069). Cream soup liking between controls and obese patients were not significantly different. However, significant sex specific differences were detected with the tested women not liking the soups (p< 0.001). Results from the food questionnaire were similar between the groups.Conclusion.No differences between non-obese persons and obese patients were regarding. However, due to highly significant differences in soup liking, sex should be taken into consideration when conducting similar sensory studies.

Before And After

Intestinal microbiota analysis of obese patients after bariatric surgery showed that Proteobacteria decreased after laparoscopic sleeve gastrectomy (SG), while it increased after laparoscopic gastric bypass (LGB). Comparing to normal weight (NW) patients, obese patients that were selected for SG showed an almost equal amount of Firmicutes and Bacteroidetes and the ratio was not affected by the surgery. Obese patients before LGB showed a predominance of Bacteroidetes, whose amount regained a relative abundance similar to NW patients after surgery. Obese patients before LGB showed the predominance of Bacteroides, which decreased after surgery in favour of Prevotella, a bacterium associated with a healthy diet. The bacteria detected at the highest percentages belonged to biofilm forming species. In conclusion, in this study, we found that the characterization of the gut microbial communities and the modality of mucosal colonisation have a central role as markers for the clinical management of obesity and promote the maintenance of good health and the weight loss.

Background and aims: Overweight and obese patients who undergo bariatric surgery require a rigorous clinical and paraclinical assessment both before and after the surgery at 3, 6, and 12 months.The present study aims the assessment of serum leptin levels and insulin resistance status in compliant bariatric patients to scheduled medical laboratory assessment at 6 months after surgery. Material and Method: The study included 109 eligible patients selected for bariatric surgery, 48 of whom attended the scheduled visit at 6 months after the surgery. Laboratory assessing regarded the insulin resistance by determining before meal the serum levels of leptin, glucose and insulin, as well as HOMA 1 and HOMA 2 indexes. Results: Patients who underwent bariatric treatment experienced a significant decrease in insulin resistance status. A higher percentage in the preoperative group was recorded in women, feature which was also recorded in the postoperative group that attended the scheduled visit at 6 months after surgery. Age is also an important factor that significantly influences the behavioral adherence to postoperative visits. Conclusions: Insulin resistance status improved significantly in 6 months after bariatric surgery among the fully compliant patients. The percentage of attendance at scheduled visits is higher among women, and decreases with age. Keywords: obesity surgery, leptin resistance, insulin resistance, HOMA index, compliance

First Time

Effects of seven different solutions prepared from various additives (carrageenan, konjac flour, phosphate, yeast extract, xanthan gum and maltodextrin) were used to test for the first time in the marination of experimental seafood. The additives were added into the marination solutions and the samples were analyzed before and after marination. Statistically, the experimental solutions did not cause significant changes in pH, acidity and salt content of the samples (P < 0.05). The highest weight gains were obtained from the solution which contained 0.1% of konjac flour (E425 I) as 4.01, 5.21, 4.61 and 4.88 % in the mussels, big squids, diced squids and small squids, respectively. However, this solution was not preferred by the panellists because of its sticky texture. Inversely to red meat products, the solution containing phosphate caused weight loss during marination. The results indicate that the solution containing 0.2% carrageenan LM (low methoxyl) was the best solution in the marination process. Dipping into this solution caused weight gains of 4.69, 2.98, 4.04 and 2.78% in the big squids, the mussels, the small squids and the diced squids, respectively (P < 0.01). The organoleptic properties (mouth feel, flavour and softness) of mussels and squids were also improved by carrageenan LM addition.

Background Obesity is associated with hypertension, but the exact mechanism is not fully understood. Bariatric surgery significantly decreases weight and blood pressure (BP). Low plasma nitric oxide (NO) and raised asymmetric dimethylarginine (ADMA), an endogenous inhibitor of NO, concentrations are associated with both obesity and hypertension. Correlations between the changes in these parameters were studied after bariatric surgery. Methods Weight, BP, plasma ADMA and NO were measured in 29 obese patients (24 female, 5 male) before and six weeks after bariatric surgery. Results Patients were 39.2 ± 1.2 (mean ± SEM) years old and weighed 126 ± 3 kg. Six weeks after the surgery, patients had lost 10 ± 0.7 kg ( P < 0.0001) and mean arterial pressure (MAP) decreased by 11 ± 1.0 mmHg ( P < 0.0001). The plasma ADMA concentration decreased by 24 ± 2% from 5 ± 0.4 to 4.0 ± 0.3 μmol/L ( P < 0.0001). The plasma total nitrite concentration increased by 15 ± 1% from 51.4 ± 2.6 to 60 ± 3 μmol/L ( P < 0.0001). The correlation between the decrease of ADMA and increase of NO subsequent to weight loss was significant ( P < 0.0001). However, MAP was not correlated to the changes in ADMA or NO. Conclusions After bariatric surgery, beneficial changes in BP, NO and ADMA occur, but our findings suggest that these BP changes are independent of changes in the NO–ADMA axis. Other causes for the changes in BP should therefore be considered.

Sustained Weight Loss

Objectives: The growing prevalence of obesity rates worldwide is associated with an upsurge in its comorbidities, particularly type 2 diabetes mellitus (T2DM). Bariatric surgery is a proven treatment modality for producing sustained weight loss and resolution of associated T2DM providing marked improvement in quality of life with rapid recovery. This study aims to investigate the effects of laparoscopic sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (RYGB), and mini-gastric bypass (MGB) on obese patients suffering from T2DM in the Indian population and their long-term association with regard to diabetes remission, resolution of comorbidities, and percentage EWL. Methods: Retrospective data of obese patients with T2DM (preoperative BMI 45.37 ± 8.1) who underwent bariatric surgery (RYGB, LSG, and MGB) were analyzed in this study over a period of 9 years. The mean follow-up period was 2.2 years. Following surgery, the clinical outcome on BMI, resolution of percentage weight loss, and T2DM were studied. The predictive factors of diabetic remission after surgery were determined. Student’s t test and ANOVA and McNemar’s test were applied. Results: Out of a total of 274 patients, complete remission of T2DM was achieved in 52.9% (n = 145) with mean fasting blood glucose and glycated hemoglobin values being 6.1 ± 0.769 (p = 0.00) at 1 year after surgery. The independent predictive factors of remission were age, gender, BMI, preoperative comorbidities, and % EWL. Gender had no correlation with the chance of achieving disease remission. Conclusion: Based on our results, bariatric surgery proves to be a successful treatment option resulting in sustained weight loss in obese patients suffering from T2DM. It is found to be beneficial for the long-term resolution of T2DM and improving comorbidities such as hypertension and dyslipidemia. The outcome of the different surgical methods is found to be similar for all patients irrespective of the independent predictors of complete remission.

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.
