Abstract
Obesity is considered a high-risk disease and a global epidemic, and the number of obese patients is rising at an alarming rate worldwide. High-fat diet-induced dysbiosis of the intestinal microbiota is considered an essential factor related to obesity. Bariatric surgery induces a sharp decrease in fat content and effectively improves the metabolism of obese individuals. Herein, we aimed to investigate the effects of a high-fat diet-induced obesity and the alterations in gastric and intestinal microbiota resulting from sleeve gastrectomy on clinical outcomes. We performed 16S sequencing of gastric and fecal samples obtained from rats in three treatment groups: normal chow diet, high-fat diet (HFD), and sleeve gastrectomy after HDF for 14 weeks. The area under the curve of fasting glucose and the levels of leptin and low-density lipoproteins were significantly different between groups. Microbial taxa that were highly correlated with several clinical parameters were identified for each group. Glyoxylate and dicarboxylate, taurine and hypotaurine, butanoate, nitrogen, and pyrimidine metabolism and aminoacyl-transfer ribonucleic acid biosynthesis were affected by bariatric surgery and were significantly associated with changes in the composition of gastric and fecal microbiomes. Connectivity and co-occurrence were higher in fecal samples than in gastric tissues. Our results elucidated the positive effects of sleeve gastrectomy in obesity and shed light on changes in the microbiomes of gastric and fecal samples.

Abstract
Obesity is a complex metabolic condition considered a worldwide public health crisis, and a deeper mechanistic understanding of obesity-associated diseases is urgently needed. Obesity comorbidities include many associated cancers and are estimated to account for 20% of female cancer deaths in the USA. Breast cancer, in particular, is associated with obesity and is the focus of this review. The exact causal links between obesity and breast cancer remain unclear. Still, interactions have emerged between body mass index, tumor molecular subtype, genetic background, and environmental factors that strongly suggest obesity influences the risk and progression of certain breast cancers. Supportive preclinical research uses various diet-induced obesity models to demonstrate that weight loss, via dietary interventions or changes in energy expenditure, reduces the onset or progression of breast cancers. Ongoing and future studies are now aimed at elucidating the underpinning mechanisms behind weight-loss-driven observations to improve therapy and outcomes in patients with breast cancer and reduce risk. This review aims to summarize the rapidly emerging literature on obesity and weight loss strategies with a focused discussion of bariatric surgery in both clinical and preclinical studies detailing the complex interactions between metabolism, immune response, and immunotherapy in the setting of obesity and breast cancer.

Abstract
Food intake is tightly controlled by homeostatic signals sensitive to metabolic need for the regulation of body weight. This review focuses on the peripherally-secreted gastrointestinal peptides (i.e., ghrelin, cholecystokinin, glucagon-like peptide 1, and peptide tyrosine tyrosine) that contribute to the control of appetite and discusses how these peptides or the signals arising from their release are disrupted in eating-related disorders across the weight spectrum, namely anorexia nervosa, bulimia nervosa, and obesity, and whether they are normalized following weight restoration or weight loss treatment. Further, the role of gut peptides in the pathogenesis and treatment response in human weight conditions as identified by rodent models are discussed. Lastly, we review the incretin- and hormone-based pharmacotherapies available for the treatment of obesity and eating-related disorders.

Impact of sleeve gastrectomy and dietary change on metabolic and hepatic function in an obesity rat model - Experimental research. Int J Surg 2020; 75:139-147. [PMID: 32014594 DOI: 10.1016/j.ijsu.2020.01.139] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 01/15/2020] [Accepted: 01/26/2020] [Indexed: 02/07/2023]
Abstract
PURPOSE Sleeve gastrectomy (SG) is an effective procedure to treat morbid obesity. SG induces remission of type 2 diabetes and metabolic syndrome and improves non-alcoholic fatty liver disease (NAFLD). However, it is imperative to clarify the extent to which these beneficial effects may be attributed to SG among other concomitant changes including postoperative diet. The current study addresses this question in a rodent model of obesity by subjecting it to SG, normal diet, or a combination of the two. METHODS Male Wistar-rats were fed with either high fat diet (HF, n = 32) or received chow diet (CD, n = 8). After 15 weeks, the HF-fed rats underwent either SG or sham operation, following which they were randomised to either continue HF or switched to CD for another 6 weeks. Body weight, fasting blood glucose level, blood pressure, and adipokine expression (leptin, adiponectin, MCP-1) in the adipose tissue along with triglycerides level in the blood serum were assessed to evaluate metabolic function. Hepatic function was assessed by histological evaluation of liver fibrosis (Hydroxyproline, Sirius Red) and reverse transcription polymerase chain reaction (RT-PCR) of the inflammation marker monocyte chemoattractant protein-1 (MCP-1). RESULTS Postoperative dietary change improved adipose tissue inflammation and arterial blood pressure regardless of the surgical intervention, while SG improved hyperglycaemia, blood triglyceride levels and, regardless of the postoperative diet, hepatic inflammation and fibrosis. However, combined administration of SG with post-operative normal diet was the most effective with regard to reducing the body weight. CONCLUSION HF for 15 weeks induced obesity with metabolic syndrome and NAFLD in rats. SG and dietary intervention improved metabolic state and NAFLD; however, their combination was significantly more effective.

Abstract
AIM Laparoscopic gastric plication (LGP) is a bariatric surgical technique based on the anatomical principles of laparoscopic sleeve gastrectomy (LSG), but its effects on the metabolic profile are still uncertain. The aim of our study is to compare the changes in weight, metabolic parameters and gastric histology following intervention by gastric plication (GP) and sleeve gastrectomy (SG) in an experimental model of obesity. METHODS To conduct the study, 32 8-week-old male Sprague-Dawley rats (Charles River®) were fattened by means of a cafeteria diet and randomly assigned to the following experimental groups: group 1: GP (n = 12); group 2: SG (n = 12) and group 3: sham (n = 8). RESULTS Unlike the SG group, the GP group attained the weight of the sham group at the end of the experiment (week 16). The GP group continued to eat more cafeteria diet than the SG group. In addition, the SG group achieved better glycaemic control than the GP group. Significantly higher plasma ghrelin levels were observed at week 16 in the GP group than in the SG group (2.29 ± 0.5 vs 1.07 ± 0.4, p < 0.05), which also occurred for the glucagon plasmatic levels (62.71 ± 36.2 vs 24.63 ± 9.3, p < 0.05). CONCLUSIONS GP is not as effective as SG and cannot be considered a metabolic surgery due to observed hormonal variations. The animals subjected to a GP continued to have a high appetite for the cafeteria diet unlike the animals submitted to an SG. Hormonal mechanisms possibly related to glucagon and ghrelin may be involved in this metabolic response.

Abstract
Restriction of food intake leads to immunologic and histomorphological changes in rats demonstrated by Moriyama. This study is planned to show how sleeve gastrectomy restricts food intake and its effects on biochemical liver function, immunologic and hematologic laboratory parameters, and histomorphological changes in rats. We used sleeve gastrectomy model on seven young adult female rats and compared study group with sham and control groups. Food consumption of rats was measured. All rats were sacrificed on the 50th day, and blood and tissue samples were collected. There was a significant low food intake in sleeve gastrectomy group (p = 0.013). No differences were observed on hematologic, biochemical, and immunologic laboratory parameters between groups. Toxicity parameters in liver samples such as cytoplasmic atrophy, single-cell hepatocellular necrosis, and necrotic eosinophilic cells were significantly high in sleeve gastrectomy group (p = 0.005). Histomorphological examination of the spleen and kidneys revealed significant changes in sleeve gastrectomy and sham groups compared with controls (p = 0.004 and p = 0.018, respectively). Although sleeve gastrectomy does not lead to alteration in hematologic, biochemical, and immunologic laboratory parameters, it causes decreased food consumption, which results in toxicological histomorphological changes in rat liver as well as some changes in kidney and spleen samples.

Abstract
Obesity has profound negative consequences on female reproduction as well as on the metabolic health of offspring. Bariatric surgery is the most effective method for sustained weight loss. A critical question is whether bariatric surgery can reverse the deleterious effects of obesity on both female reproduction and subsequent offspring. Vertical sleeve gastrectomy (VSG) is a bariatric procedure rapidly growing in popularity because it provides weight loss and other metabolic benefits that are comparable to those offered by the more complicated Roux-en-Y gastric bypass (RYGB). Female rats rendered obese on a high-fat diet (HFD) underwent either VSG or sham surgery. Like their male counterparts, females had significant metabolic improvements including reduced adiposity and improved glucose tolerance. After VSG, female rats showed a more normal reproductive cycle. Despite these maternal benefits, the offspring of dams receiving VSG were born smaller and lighter than offspring of control dams that underwent sham surgery. When maintained on an HFD after puberty, these adult offspring had a greater propensity to develop glucose intolerance and increased adiposity than the offspring of lean mothers or obese mothers who underwent sham surgery. These data suggest that weight loss alone by obese mothers is not sufficient to reverse the deleterious effects of an HFD and obesity on their offspring.

Abstract
The sudden improvement of metabolic profile and the remission of type 2 diabetes after bariatric surgery, well before weight loss, raise important new questions regarding glycemic control. Currently, various types of bariatric procedures target type 2 diabetes in obese and non-obese patients. Nevertheless, the origin of the dramatic metabolic improvements, including glucose homeostasis, is poorly understood, and the role of the gastrointestinal (GI) tract remains relatively speculative, as well as why these procedures are variably effective. One neglected explanation is that such interventions disrupt neural networks mediating GI-brain communication and could alter the autonomic output to the visceral organs, including the liver. Incretins, e.g., glucagon-like peptide 1 (GLP-1), have major influence on the central nervous system. Moreover, the level of GLP-1 is observed to significantly increase after bariatric surgery and could be a key factor in the weight-independent, anti-diabetic effect. Therefore, this review will evaluate the effect of GLP-1 on the central nervous system, with emphasis on the cellular effects of GLP-1, and will provide an overview of the autonomic control of the liver.
