Vargas CM, Gómez D, Madrigal V, Guilbert L, Sepúlveda EM, Rodríguez FM, Zerrweck C. Women with Anemia Refractory to Oral Iron Treatment Following Bariatric Surgery: a Short-Term Analysis. Obes Surg 2023; 33:846-850. [PMID: 36602723 DOI: 10.1007/s11695-022-06447-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 12/28/2022] [Accepted: 12/30/2022] [Indexed: 01/06/2023]
Abstract
INTRODUCTION Iron deficiency and anemia are common after bariatric surgery. Women have a higher risk of developing such long-term complications. Though oral supplementation is indicated, intravenous iron therapy is required in some cases. METHODS This retrospective study included patients who underwent bariatric surgery between 2012 and 2018. Postoperative anemia patients receiving parental iron therapy were assessed during the first 24 months. Their baseline characteristics, surgery type, and laboratory test results were analyzed. A follow-up analysis included a subgroup of women with and without gynecological disorders. Patients with vitamin B12 or folic acid deficiencies were excluded. RESULTS Six hundred eleven (63.3%) met the inclusion criteria: 525 underwent gastric bypass, of which 79.6% were women. Overall, postoperative anemia was 28.9% (24.5% related to gastric bypass), especially among women (84%). Anemia refractory to oral iron therapy was observed in 12.9% of patients. All the patients requiring iron infusions (n = 54) were women, and half of them (51.8%) reported abnormal uterine bleeding. Postsurgical hemogram values were significantly lower in patients with abnormal uterine bleeding (despite the same number of infusions) than in those without gynecological disorders; 89.2% of these women had preoperative anemia. CONCLUSION Anemia is frequent in bariatric surgery patients despite supplementation. Women undergoing gastric bypass with a history of gynecological disorders are prone to require more iron infusions. Consulting with the patient about a higher risk is important, and probably knowing the plan or including the opinion of an OBGYN to determine as a team the assessment, treatment, and prognosis.

Abstract
PURPOSE This study aims to investigate the rate of short- and long-term complications as well as the need for operative revisions after abdominoplasty for patients following surgical versus non-surgical weight loss methods. METHODS This is a retrospective chart review that enrolled consecutive patients undergoing abdominoplasty across a 5-year period, aged 18 years and above, opting for abdominoplasty after weight loss achieved through bariatric surgery or diet and exercise alone. RESULTS A total of 364 patients lost weight through bariatric surgery and 106 by diet and exercise alone. There were no significant differences in comorbidity status, but past body mass index (BMI) was higher for the surgical weight loss (SW) group (47.6 ± 10.2 and 40.4 ± 8.6, respectively; p value < 0.0001). Percent excess weight loss (EWL) was 68 ± 14.5 for the SW group and 55.7 ± 19.4 for the NSW group, p value < 0.0001. Pre- and postoperative blood hemoglobin levels were significantly lower in the SW group (p < 0.05). Neither short-term complications (thromboembolic events, wound complications, or infections) nor long-term complications (umbilical deformity, delayed wound healing, or infection) and operative revisions were significantly different across both groups (p > .05). CONCLUSION Bariatric surgery does not increase the risk of short- or long-term complications or the need for operative revision after abdominoplasty.

Abstract
BACKGROUND Several studies have reported short and medium-term outcomes of laparoscopic sleeve gastrectomy (LSG) in patients with class I obesity and type 2 diabetes mellitus (T2DM). However, literature on outcomes beyond three years is scarce. The present study discusses the 5-year results of a previously reported cohort of 20 patients with class I obesity and T2DM, who had undergone LSG between March 2012 and March 2015. MATERIALS AND METHODS Patients were followed up in the bariatric clinic at yearly intervals as per institute protocol. Primary outcome was proportion of patients with a glycated haemoglobin (HbA1c) level of 6.5% or less, 5 years after LSG. Secondary outcomes were percentage total weight loss (%TWL), excess weight loss (EWL), weight regain and complications. RESULTS Out of 20 patients, 9 (45%) were male and 11 (55%) were female. Mean age was 41.6 ± 9.5 years. Mean pre-operative weight and BMI were 94.8 ± 14.4 kg and 33.4 ± 1.2 kg/m2, respectively. Median duration of diabetes was 42 months. Mean pre-operative fasting plasma glucose (FPG) and HbA1c were 171.1 ± 56.8 mg/dL and 8.7 ± 1.6%, respectively. Of the 17 patients available for follow-up at 5 years, 9 (52.9%) achieved HbA1c < 6.5% without medication, while 7 (41.2%) patients had improvement of their glycaemic status. One patient had recurrence of diabetes after initial remission. Mean %TWL and %EWL were 18% and 65.1%, respectively. CONCLUSION Laparoscopic sleeve gastrectomy is a reasonable option as a metabolic procedure for patients with T2DM and class I obesity.

Abstract
Type 2 diabetes (T2D), which has currently become a global pandemic, is a metabolic disease largely characterised by impaired insulin secretion and action. Significant progress has been made in understanding T2D aetiology and pathogenesis, which is discussed in this review. Extrapancreatic pathology is also summarised, which demonstrates the highly multifactorial nature of T2D. Glucagon-like peptide (GLP)-1 is an incretin hormone responsible for augmenting insulin secretion from pancreatic beta-cells during the postprandial period. Given that native GLP-1 has a very short half-life, GLP-1 mimetics with a much longer half-life have been developed, which are currently an effective treatment option for T2D by enhancing insulin secretion in patients. Interestingly, there is continual emerging evidence that these therapies alleviate some of the post-diagnosis complications of T2D. Additionally, these therapies have been shown to induce weight loss in patients, suggesting they could be an alternative to bariatric surgery, a procedure associated with numerous complications. Current GLP-1-based therapies all act as orthosteric agonists for the GLP-1 receptor (GLP-1R). Interestingly, it has emerged that GLP-1R also has allosteric binding sites and agonists have been developed for these sites to test their therapeutic potential. Recent studies have also demonstrated the potential of bi- and tri-agonists, which target multiple hormonal receptors including GLP-1R, to more effectively treat T2D. Improved understanding of T2D aetiology/pathogenesis, coupled with the further elucidation of both GLP-1 activity/targets and GLP-1R mechanisms of activation via different agonists, will likely provide better insight into the therapeutic potential of GLP-1-based therapies to treat T2D.

Aljaaly EA. Perioperative nutrition care and dietetic practices in the scope of bariatric surgery in Saudi Arabia using adapted protocols for evaluation. SAGE Open Med 2021; 9:20503121211036136. [PMID: 34377474 PMCID: PMC8326630 DOI: 10.1177/20503121211036136] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Accepted: 07/11/2021] [Indexed: 12/14/2022] Open
Abstract
Objectives: This study evaluates the availability of perioperative nutritional care protocols and the practices of bariatric registered dietitians in Saudi Arabia. The primary outcomes of the study were conducted using an adapted American survey “with permission.” Methods: A cross-sectional survey of a selected 32 dietitians providing bariatric services completed a self-administered online questionnaire from 12 hospitals in Jeddah, Saudi Arabia. Results: All surveyed dietitians were females, mainly Saudi nationals (93.9%, n = 30), and accredited by the Saudi Commission for Health Specialties (93.8%, n = 30). Only 37.5% (n = 6) of the dietitians were specialized in bariatric surgery. Perioperative common practices of dietitians included a conduct of screening for nutrition risk before (44%, n = 14) and after surgery (62.5%, n = 20) and applied a nutrition management protocol that is mainly based on the application of nutrition care process (62.5%, n = 20). Dietitians (81%, n = 26) reported the importance of having standardized protocols for nutritional management of patients undoing bariatric surgery, where 69% (n = 22) confirmed the availability of pre-operative written protocols in hospitals and 75% (n = 24) confirmed the existence of post-operative protocols. Pre-operative practices included using approaches for weight loss before surgery, for example, very low and low-calorie diet. Dietitians (25%, n = 8) see two to ten patients per month. The sleeve gastrectomy procedure is the most often performed surgery. Conclusion: This is the first study to evaluate the perioperative nutrition care protocols and practices related to bariatric surgery in Saudi Arabia. Perioperative bariatric protocols are available, but some dietitians are not aware of their availability and contents. Researchers emphasize the importance of creating national protocols by the Saudi Credentials Body to standardize practices within the field.

Abstract
Nowadays, obesity represents one of the most unresolved global pandemics, posing a critical health issue in developed countries. According to the World Health Organization, its prevalence has tripled since 1975, reaching a prevalence of 13% of the world population in 2016. Indeed, as obesity increases worldwide, novel strategies to fight this condition are of the utmost importance to reduce obese-related morbidity and overall mortality related to its complications. Early experimental and initial clinical data have suggested that endovascular bariatric surgery (EBS) may be a promising technique to reduce weight and hormonal imbalance in the obese population. Compared to open bariatric surgery and minimally invasive surgery (MIS), EBS is much less invasive, well tolerated, with a shorter recovery time, and is probably cost-saving. However, there are still several technical aspects to investigate before EBS can be routinely offered to all obese patients. Further prospective studies and eventually a randomized trial comparing open bariatric surgery vs. EBS are needed, powered for clinically relevant outcomes, and with adequate follow-up. Yet, EBS may already appear as an appealing alternative treatment for weight management and cardiovascular prevention in morbidly obese patients at high surgical risk.

Abstract
PURPOSE Dumping syndrome (DS) is an important but often underreported problem occurring after bariatric surgery. It is believed that gastric bypass procedures like Roux-en-Y Gastric By-pass (RYGB) and One-Anastomosis Gastric Bypass (OAGB) are more likely to cause DS than the pylorus-preserving Sleeve Gastrectomy (SG). The aim of this study was to evaluate the incidence of DS in patients undergoing SG, RYGB and OAGB. MATERIALS AND METHODS A retrospective clinical study with 180 patients undergoing SG (n=50), RYGB (n=53) and OAGB (n=77) between 2016-2018 was performed. All clinical and demo-graphic data were assessed. The percentage of excess weight loss (%EWL) was used to evaluate weight reduction. 127/180 (70.6%) patients took part in an additional phone interview. The incidence of DS was evaluated using validated Sigstad Score. RESULTS Information about the occurrence of dumping symptoms and patient satisfaction was obtained from 127 patients. Median follow-up was 20.0±11.4 months. Significant differences between the surgical procedures were found for the duration of surgery, complications, weight loss, incidence of DS and satisfaction postoperatively. DS occurred in 15.6% after SG, 56.4% after RYGB and 42.9% after OAGB. A higher weight loss was observed in patients who experienced dumping symptoms. CONCLUSION The present results show a clear superiority of SG regarding both perioperative results and incidence of DS compared to RYGB and OAGB and may impact clinicians and patients in their choice of procedure.

Abstract
BACKGROUND & AIMS Pharmacologic agents targeting bile acid signaling show promise for treating nonalcoholic steatohepatitis (NASH). However, clinical findings suggest that new treatment strategies with enhanced therapeutic efficacy and minimized undesired effects are needed. This preclinical study investigates whether combining an apical sodium-bile acid transporter (ASBT) inhibitor GSK233072 (GSK672) and fibroblast growth factor-15 (FGF15) signaling activation improves anti-NASH efficacy. METHODS Mice with high fat, cholesterol, and fructose (HFCFr) diet-induced NASH and stage 2 fibrosis are used as a NASH model. GSK672 or AAV8-TBG-FGF15 interventions are administered alone or in combination to HFCFr diet-fed mice. RESULTS The combined treatment significantly enhances therapeutic efficacy against steatosis, inflammation, ballooning, and fibrosis than either single treatment. Mechanistically, the synergistic actions of GSK672 and FGF15 on inhibiting gut bile acid reuptake and hepatic bile acid synthesis achieve greater magnitude of bile acid pool reduction that not only decreases bile acid burden in NASH livers but also limits intestinal lipid absorption, which, together with FGF15 signaling activation, produces weight loss, reduction of adipose inflammation, and attenuated hepatocellular organelle stress. Furthermore, the combined treatment attenuates increased fecal bile acid excretion and repressed bile acid synthesis, which underlie diarrhea and hypercholesterolemia associated with ASBT inhibition and FGF19 analogue, respectively, in clinical settings. CONCLUSIONS Concomitant ASBT inhibition and FGF15 signaling activation produce metabolic changes that partially mimic the bariatric surgery condition whereby lipid malabsorption and increased FGF15/19 signaling synergistically mediate weight loss and metabolic improvement. Further clinical studies may be warranted to investigate whether combining ASBT inhibitor and FGF19 analogue enhances anti-NASH efficacy and reduced treatment-associated adverse events in humans.

Abstract
Body contouring surgery after the massive weight loss due to bariatric surgery deals with different kinds of complications. The aim of this review is to analyze the role that some nutrients may play in tissue healing after surgery, thus helping plastic surgeons to improve the aesthetic and health outcomes in massive weight loss patients under a multidisciplinary approach. As a matter of fact, preoperative nutritional deficiencies have been shown for vitamins and minerals in a large percentage of post-bariatric patients. Preoperative deficiencies mainly concern iron, zinc, selenium, and vitamins (both fat-soluble and water-soluble), but also total protein. During the postoperative period, these problems may increase because of the patients' very low intake of vitamins and minerals after bariatric surgery (below 50% of the recommended dietary allowance) and the patients' low compliance with the suggested multivitamin supplementation (approximately 60%). In the postoperative period, more attention should be given to nutritional aspects in regard to the length of absorptive area and the percentage of weight loss.

Abstract
Post bariatric control of food intake is influenced by psychological and behavioral factors. We investigated dietary habits and food intake during COVID-19 quarantine among recently operated patients. Patients were assessed for total and per meal energy and macronutrient intake as well as frequency of food consumption per processing level. Patients were also classified according to adherence to nutritional recommendations from our outpatient clinic. Main results are indicative of inappropriate nutritional intake during COVID-19 quarantine in postoperative bariatric patients. We observed that many patients failed to meet the recommended protein intake (89.2%) along a relatively high intake of ultra-processed foods (~1/4 of the diet). Our data suggest the need for the implementation of strategies to extend nutritional care to at-risk patients during social distancing.

Abstract
BACKGROUND Dumping syndrome (DS) is a common complication of bariatric surgery. Treatments include dietary and behavioral changes, as well as pharmacotherapy and revision surgery. All can be costly or hard to adhere to. In recent years, evidence accumulates in favor of endoscopic trans-oral outlet reduction (TORe) as an effective treatment for DS, targeting the pathophysiology of rapid gastric clearance. The objective of this study is to assess the safety and efficacy of TORe for DS in a single referral center. METHODS Patients after bariatric surgery suffering DS were followed, and data were retrospectively analyzed. Diagnosis and post-procedural assessment of DS were made clinically using Sigstad score. During the procedure, the anastomotic rim was cauterized. Afterwards, 2 non-interrupted "8-figure" sutures were placed, resulting in imbrication of additional gastric tissue on top of the anastomosis and narrowing to <1 cm at the end of the procedure. Patients were instructed to keep a liquid diet for 14 days and follow-up continued for 6 months. RESULTS Between 8/2018 and 9/2019 TORe was carried out in 13 patients (M:F = 3:10) with mean age of 45.1 (range 25-56) and BMI of 33.5 (range 28.1-40.3). Average time since recent surgery was 5.5 years (range 1-9). Mean pre-procedure anastomosis diameter was 25.2 mm (range 15-30) and was reduced to a mean of 5.6 mm (range 5-10). Three patients (23%) were admitted overnight due to inability to drink which resolved spontaneously. No major complications were reported. At 6 months, the Sigstad score was significantly reduced (19.4 ± 3.6 vs 5.2 ± 5.5, P < 0.001), and 11/13 (85%) of patients had a complete resolution of their dumping symptoms. In addition, BMI decreased by a mean of 2.3 kg/m2 (-1 to 7.5, p = 0.002). CONCLUSION TORe is a safe and effective treatment for patients suffering dumping syndrome and should be considered early in the treatment of DS.

Abstract
BACKGROUND Bariatric surgery (BS) is considered as an effective solution to control morbid obesity. Food restrictions resulting from the operation may decrease dietary nutrient intakes, particularly during the first year after BS. This study mainly aimed to assess the adequacy of dietary nutrient intakes at 6th and 12th month after BS. METHOD Of the severely obese participants in the Tehran obesity treatment study in 2015-2016, 58 patients undergoing Roux-En-Y gastric bypass (N = 16) or sleeve gastrectomy (N = 42) were selected from Tehran Obesity Treatment Center. To assess the patients' dietary intake, a three-day, 24-h dietary recall was obtained on three unscheduled days (two non-consecutive weekdays and one weekend day) at 6th and 12th month after BS. To evaluate the adequacy of nutrient intake, the patients' intakes were compared to the current dietary reference intakes (DRIs), including estimated average requirements (EAR) or Adequate Intakes (AI). RESULTS The mean age of the participants (71% women) undergoing BS was 37 ± 8 years. Anthropometric parameters significantly decreased at the 12th month after BS. The percentage of energy from carbohydrate intake increased significantly between the 6th and 12th month after BS (P = 0.04). The mean ± SD of protein intake was lower than the recommended dosage with a dramatic decrease from 45 ± 30 to 31 ± 15 (g/day) between the two intervals (P = 0.001). The mean intake of saturated fatty acid (SFA) decreased dramatically (P < 0.001) from 6 to 12 month; however, the median intake of n3-polyunsaturated fatty acid (n3-PUFA) intake increased (P = 0.02). None of the participants showed nutrient intake adequacy in terms of biotin, fat soluble vitamins, pantothenic acid, potassium, and zinc. Moreover, less than 10% of the participants showed nutrient intake adequacy in terms of folate, magnesium, manganese, and calcium according to DRIs during the both intervals after BS. CONCLUSION Bariatric surgery can reduce dietary intakes, which is more obvious 12 months after the surgery. Out of 21 micronutrients, nearly all could not met the EAR and were received < 50%, also had significant reduction from the 6th to12th month after surgery.

Abstract
AbstractObesity is a developed nutritional problem, and today, surgery is one of the approaches to cure it. A good understanding of the variations in food intake will be beneficial for sustaining long-term weight loss post-surgery and for improving nutrition care strategies. The purpose of this review was the comparison of the impact of two methods of gastric bypass (GBP) and sleeve gastrectomy (SG) on dietary intake. Databases of PubMed, Embase, Scopus, Google Scholar, and Web of science were used for the literature search up to June 2018. We concluded the studies that measured mean daily energy intake and the percent of macronutrients from total calorie intake of before and after GBP and SG. A total of 18 studies were finally included in the meta-analysis for the effect of bariatric surgery on food intake. Bariatric surgery significantly decreased energy intake by 1050.04 kcal/day (p < 0.001) compared with the baseline values of energy intake. The pooled effect of bariatric surgery on protein intake was 0.82 g/day (p = 0.004) compared with the baseline values. The pooled analysis found no significant impact of bariatric surgery on carbohydrate intake (WMD = 0.56 g/day; p = 0.40) compared with the baseline values. The pooled estimate of effect for bariatric surgery on fat intake was - 1.34 g/day (p = 0.006). This study demonstrates that bariatric surgery might be effective on energy and fat intake; however, there was no effect on carbohydrate intake.

Abstract
Cardiac autonomic neuropathy (CAN) is a major complication of type 1 and type 2 diabetes mellitus (T1DM and T2DM). The increased morbidity, cardiovascular and all-cause mortality associated with CAN is established from numerous epidemiological studies. However, CAN is increasingly recognised in people with prediabetes (pre-DM) and the metabolic syndrome (MetS) with a reported prevalence up to 11% and 24% respectively. CAN is associated with components of MetS including hypertension and obesity, predating hyperglycaemia. The aetiology of CAN is multifactorial and there is a reciprocal relationship with insulin resistance and MetS. Obstructive sleep apnoea (OSA) is also associated with CAN possibly through MetS and an independent mechanism. An estimated global prevalence of the impaired glucose tolerance (IGT) form of pre-DM of 587 million people by 2045 means CAN will become a major clinical problem. CAN is independently associated with silent myocardial ischaemia, major cardiovascular events, myocardial dysfunction and cardiovascular mortality. Screening for CAN in pre-DM using risk scores with analysis of heart rate variability (HRV) or Sudoscan is important to allow earlier treatment at a reversible stage. The link between obesity and CAN highlights the therapeutic potential of lifestyle interventions including diet and physical activity to reverse MetS and prevent CAN. Weight loss achieved using these dietary and exercise lifestyle interventions improves the sympathetic and parasympathetic HRV indices of cardiac autonomic function. Further research is needed to identify high-risk populations of people with pre-DM or obesity that might benefit from targeted pharmacotherapy including metformin, sodium/glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide 1 (GLP-1) analogues. Bariatric surgery also improves HRV through weight loss which might also prevent CAN in severe obesity. This article reviews the literature on CAN in obesity, pre-DM and MetS, to help determine a rationale for screening, early intervention treatment and formulate future research questions in this highly prevalent condition.

Abstract
Gastrointestinal (GI) motility disorders are major contributing factors to functional GI diseases that account for >40% of patients seen in gastroenterology clinics and affect >20% of the general population. The autonomic and enteric nervous systems and the muscles within the luminal GI tract have key roles in motility. In health, this complex integrated system works seamlessly to transport liquid, solid, and gas through the GI tract. However, major and minor motility disorders occur when these systems fail. Common functional GI motility disorders include dysphagia, gastroesophageal reflux disease, functional dyspepsia, gastroparesis, chronic intestinal pseudo-obstruction, postoperative ileus, irritable bowel syndrome, functional diarrhea, functional constipation, and fecal incontinence. Although still in its infancy, bioelectronic therapy in the GI tract holds great promise through the targeted stimulation of nerves and muscles.

Abstract
Bariatric surgery (BS) may be effective for chronic kidney disease (CKD) patients by reducing microalbuminuria and proteinuria, and by facilitating their meeting inclusion criteria for kidney transplantation. However, nutritional management for this population is complex and specific guidelines are scarce. A literature search was performed to create dietetic practice for these patients based on the most recent evidence. For the purposes of nutritional recommendations, we divided the patients into 2 subgroups: 1) patients with CKD and dialysis, and 2) patients after kidney transplantation. Before surgery, nutritional care includes nutritional status evaluation and adjusting doses of supplements to treat deficiencies and daily nutrient intake according to the dietary restrictions derived from kidney disease, including quantities of fluids, protein, phosphorus, potassium, and vitamins. After BS, these patients are at major risk for lean body mass loss, malnutrition and dehydration because of fluid restriction and diuretics. Postoperative nutritional recommendations should be carefully tailored according to CKD nutritional limitations and include specific considerations regarding protein, fluids, and supplementation, in particular calcium, vitamin A, and vitamin D. Nutritional management of CKD and kidney transplant patients undergoing BS is challenging and future studies are required to establish uniform high-level evidence-based guidelines.

Abstract
Obesity may be counteracted by increased energy expenditure. Circulating molecules act in the adipose tissue to influence brown and beige adipocyte function, differentiation, and thermogenic capacity, which in turn affects substrate utilization and impacts energy balance at the organismal level. These molecules have been envisioned as biomarkers and potential candidates for pharmacological interventions to treat obesity. Here we summarize studies that demonstrate the roles of endogenous circulating molecules of a wide variety in regulating the thermogenic potential of brown and beige fat cells. This review describes the state-of-the-art in the field and helps researchers to prioritize their targets in future studies.

Abstract
BACKGROUND AND AIM No study has compared the incidence of postoperative bone metabolic disorders between Billroth-I (B-I) and Roux-en-Y (R-Y) reconstructions after distal gastrectomy (DG) for gastric cancer (GC). In this study, we wished to examine the impact of reconstruction method on postoperative bone mineral density (BMD) loss. METHODS We investigated a total of 148 consecutive patients who underwent DG with B-I or R-Y reconstruction for stage I GC between 2008 and 2012. We retrospectively assessed the BMD data using computed tomography attenuation values of the first lumbar vertebra after surgery. RESULTS In multivariate analysis for the whole study series, R-Y reconstruction was identified as an independent risk factor for BMD loss after DG (P < 0.0001; OR = 5.60; 95% CI = 2.38-13.98). Propensity score match analysis was used to overcome bias because of the different covariates for the two groups; even though the 37 patients in the B-I group and the 37 patients in the R-Y group had no significant difference among characteristics, B-I reconstruction was validated to have superiority over R-Y reconstruction for preventing BMD loss in the first 3 years after DG. The cumulative hazard ratio of osteoporosis after gastrectomy was significantly higher in the R-Y group than in the B-I group (P = 0.0427). CONCLUSIONS Billroth-I reconstruction might be a preferable method for preventing BMD loss after gastrectomy in GC patients.

Abstract
BACKGROUND Vitamin supplementation in bariatric aftercare is essential to prevent nutrient deficiencies; however, rates of vitamin adherence have been as low as 30 % 6 months post-surgery. Preliminary literature suggests non-adherence to prescribed treatments can be linked to demographic and psychological factors. We aimed to determine the relationship between these factors to vitamin adherence in post-bariatric surgery patients. METHODS A total of 92 bariatric patients were assessed 6 months post-surgery. Patients were administered a questionnaire collecting demographic information, psychological scores, and self-reported adherence. Nutrient deficiencies were analyzed through serum vitamin levels measured 3 and 6 months after surgery. Wilcoxon rank-sum and chi-square tests were used for analysis. RESULTS Non-adherence was associated with male sex and full-time employment (p = 0.027, p = 0.015). There were no differences with respect to living situation, education level, or relationship type. Non-adherent patients did not have significantly higher scores for generalized anxiety, depressive symptoms, or avoidant behaviors. However, non-adherent patients displayed greater attachment anxiety than their adherent counterparts (p = 0.0186). Non-adherence was also associated with lower vitamin B12 levels 6 months post-surgery (p = 0.001). CONCLUSIONS Male gender and full-time work have previously been shown to be associated with non-adherence. This is the first study to demonstrate that attachment anxiety is associated with poor multivitamin adherence in the post-surgical bariatric population. This result is concordant with recent literature that has demonstrated attachment anxiety is associated with poor adherence to dietary recommendations in bariatric patients 6 months postoperatively. Presurgical screening for attachment anxiety could facilitate early interventions to promote better bariatric aftercare in this group.

Abstract
BACKGROUND In animal studies, copper absorption has been demonstrated to occur in the proximal gut via duodenal enterocytes. Acquired copper deficiency is known as "swayback" in ruminant animals and Menkes' disease in humans. Copper is an essential micronutrient necessary for the hematologic and neurologic systems. Acquired copper deficiency in humans has been described, causing a syndrome similar to the subacute combined degeneration of vitamin B(12) deficiency. METHODS This is a single case report. Our patient developed a neurologic constellation of ataxia, myelopathy, and peripheral neuropathy similar to vitamin B(12) deficiency many years after gastrectomy for severe peptic ulcer disease. The patient was maintained for decades with enteral feedings via jejunostomy that provided the recommended dietary allowance (RDA) for copper. RESULTS Copper deficiency was suspected, identified, and treated. Over 3 months of follow-up, serum copper levels increased from 4 microg/dL to 20 microg/dL (70-150 microg/dL), and ceruloplasmin increased from 6 mg/dL to 8 mg/dL (14-58 mg/dL). During this short time of follow-up, the patient has had no further progression of his neurologic symptoms. CONCLUSIONS Ataxia and myelopathy secondary to acquired copper deficiency are rare complications of major gastric resection. This is quite similar to the syndrome of vitamin B(12) deficiency. Vitamin B(12) repletion does not improve symptoms. Bariatric procedures such as gastric bypass surgery result in a similar functional anatomy of the proximal gut and may place more patients at increased risk. Early recognition and therapy with oral or parenteral copper may lead to a decrease in both neurologic and hematologic consequences.

Abstract
OBJECTIVE Drug malabsorption is one of the potential troubles after bariatric surgery. Evidence for diminished levothyroxine (L-T4) absorption has been reported in patients after bariatric surgery. METHODS This study reports 17 cases of hypothyroid patients [who were well replaced with thyroxine tablets (for >1 year) to euthyroid thyrotropin (TSH) levels before surgery (13 Roux-en-Y gastric bypasses (RYGB); 4 biliary pancreatic diversions (BPD))]. From 3 to 8 months after surgery, these patients had elevated TSH levels. Patients were then switched from oral tablets to a liquid L-T4 formulation (with the same dosage, 30 min before breakfast). RESULTS Two-three months after the switch, TSH was significantly reduced both in patients treated with RYGB, as in those treated with BPD, while FT4 and FT3 levels were not significantly changed (RYGB group, TSH μIU/mL: 7.58 ± 3.07 vs 3.808 ± 1.83, P < 0.001; BPD group, TSH μIU/mL: 8.82 ± 2.76 vs 3.12 ± 1.33, P < 0.01). CONCLUSIONS These results first show that liquid L-T4 could prevent the problem of malabsorption in patients with BPD and confirm those of previous studies in patients submitted to RYGB, suggesting that the L-T4 oral liquid formulation could circumvent malabsorption after bariatric surgery.

Abstract
Bariatric surgery is currently the most effective treatment for morbid obesity and its associated metabolic complications. To ensure long-term postoperative success, patients must be prepared to adopt comprehensive lifestyle changes. This review summarizes the current evidence and expert opinions with regard to nutritional care in the perioperative and long-term postoperative periods. A literature search was performed with the use of different lines of searches for narrative reviews. Nutritional recommendations are divided into 3 main sections: 1) presurgery nutritional evaluation and presurgery diet and supplementation; 2) postsurgery diet progression, eating-related behaviors, and nutritional therapy for common gastrointestinal symptoms; and 3) recommendations for lifelong supplementation and advice for nutritional follow-up. We recognize the need for uniform, evidence-based nutritional guidelines for bariatric patients and summarize recommendations with the aim of optimizing long-term success and preventing complications.

Abstract
No studies have examined scars and quality of life after different treatments of wound dehiscence in patients undergoing post-bariatric abdominoplasty. Scars and quality of life of patients with postoperative wound dehiscence managed with negative pressure wound therapy (group A) and conventional wound therapy (group B) were reviewed 6 months after wound healing. Of 38 patients undergoing treatment for wound dehiscence after 203 abdominoplasty, 35 (group A = 14 versus group B = 21) entered the study. Wound healing in group A was significantly faster than group B (P = 0·001). Patients (P = 0·0001) and observers (P = 0·0001) reported better overall opinions on a scar assessment scale for group A. Better overall quality of life and general health satisfaction were observed in group A (P < 0·05). A significant correlation was observed between the World Health Organization Quality of Life scores and Patient and Observer Scar Assessment Scale scores (r=-0·68, P < 0·0001) in all 35 patients. Negative pressure wound therapy is feasible and effective in patients with wound dehiscence following post-bariatric abdominoplasty. An adequate post-treatment outcome is achieved compared with conventional wound therapy in light of a strong association found between worse patient scar self-assessment and poor overall quality of life, regardless of the received treatment.

Abstract
PURPOSE Single anastomosis sleeve ileal bypass (SASI) procedure appears as a new metabolic and bariatric surgery based on Santoro's operation, in which a sleeve gastrectomy is followed by a side-to-side gastroileal anastomosis. The study is aimed to evaluate the short-term outcomes of laparoscopic single anastomosis sleeve ileal bypass with respect to postoperative weight loss and metabolic and nutritional effects on patients. METHODS Forty-five morbidly obese patients with a mean age of 31.2 years and a mean body mass index (BMI) of 43.2 kg/m2 underwent SASI bypass. Postoperatively, all patients were followed up at 1, 3, 6, and 12 months, and during each visit data about their BMI, obesity-related comorbidities, and nutritional status were collected. RESULTS One year after the surgery, mean BMI decreased to 29.1 kg/m2 and there was significant decrease in plasma level of fasting blood glucose, insulin, and low-density lipoprotein. On the other hand, there was significant increase in high-density lipoprotein plasma level, whereas hemoglobin and albumin plasma level remained normal. Six months after the surgery, calcium plasma level showed mild decrease in two cases, which was improved with multivitamin tablets. In 93% of our patients, multivitamin supplements were stopped after six months of surgery. CONCLUSIONS Laparoscopic SASI bypass has been shown to be an effective, safe, and simple procedure for the treatment of morbid obesity and its associated metabolic consequences. Moreover, it results in minimal postoperative nutritional complications in comparison to other bariatric procedures.

Abstract
Early dumping syndrome after gastric bypass surgery due to rapid delivery of hyperosmolar nutrients into the bowel causing intense symptoms is often described as a complication. Twelve patients, mean age 47 years, were interviewed approximately 9 years post-operation. The interviews were audiotaped and transcribed verbatim, followed by an inductive content analysis to reveal patients' experience of the dumping syndrome. The core category 'Dumping syndrome is a positive consequence of Roux-en-Y gastric bypass surgery and a tool to control food intake' was identified based on the following four sub-categories: (i) 'The multidimensional emergence and effects of dumping syndrome', (ii) 'Dumping syndrome as something positive although unpleasant', (iii) 'Developing coping mechanisms and ingenious strategies' and (iv) 'My own fault if I expose myself to dumping syndrome'. From the patients' perspective, dumping syndrome gives control over food intake; although the symptoms were unpleasant, patients considered dumping syndrome as a positive protection against over-consumption. Hence, healthcare professionals should not present dumping syndrome as a complication but rather as an aid to control eating behaviour and excessive food intake.

Abstract
INTRODUCTION The most recent advance concerning levothyroxine (L-T4) therapy is the development of novel oral formulations: the liquid preparation, and the soft gel capsule. Areas covered: This review evaluates the most recent clinical studies about these new formulations. The liquid formulation has been shown to overcome: the food and beverages intereference with L-T4 tablets absorption, caused by food or coffee at breakfast; malabsorption induced by the increased gastric pH, resulting from atrophic gastritis, or due to proton-pump inhibitors; and malabsorption after bariatric surgery. The use of liquid L-T4 has been studied also in pregnancy, newborns and infants, suggesting a better bioequivalence than tablets. Finally, liquid L-T4 is more active than tablets in the control of thyroid-stimulating hormone (TSH) in hypothyroid patients without malabsorption, drug interference, or gastric disorders, leading to a hypothesized higher absorption of liquid L-T4 also in these patients. Few studies have evaluated soft gel L-T4 with promising results in patients with malabsorption related to coffee or gastritis. Expert opinion: Liquid L-T4 (and soft gel capsules) are more active than the tablet L-T4 in the control of TSH in hypothyroid patients with gastric disorders, malabsorption, or drug interference, but also in patients without absorption disorders.

Abstract
Bariatric surgery can facilitate weight loss and improvement in medical comorbidities. It has a profound impact on nutrition, and patients need access to follow-up and aftercare. NICE CG189 Obesity emphasized the importance of a minimum of 2 years follow-up in the bariatric surgical service and recommended that following discharge from the surgical service, there should be annual monitoring as part of a shared care model of chronic disease management. NHS England Obesity Clinical Reference Group commissioned a multi-professional subgroup, which included patient representatives, to develop bariatric surgery follow-up guidelines. Terms of reference and scope were agreed upon. The group members took responsibility for different sections of the guidelines depending on their areas of expertise and experience. The quality of the evidence was rated and strength graded. Four different shared care models were proposed, taking into account the variation in access to bariatric surgical services and specialist teams across the country. The common features include annual review, ability for a GP to refer back to specialist centre, submission of follow-up data to the national data base to NBSR. Clinical commissioning groups need to ensure that a shared care model is implemented as patient safety and long-term follow-up are important.

Abstract
Morbid obesity is a worldwide health concern that compromises life quality and health status of obese human subjects. Bariatric surgery for treating morbid obesity remains as one of the best alternatives to promote excess weight loss and to reduce co-morbidities. We have not found studies reporting nutrients and energy balance considering digestibility trials in humans following surgery. The purpose of this study was to determine protein, lipid, fiber, energy, calcium, and phosphorous digestibility in a swine model that underwent ileal transposition (IT), sleeve gastrectomy with ileal transposition (SGIT), Roux-en-Y gastric bypass (RYGBP), and with sham operated animals (SHAM). Thirty-two pigs were randomly assigned to four laparoscopic procedures: IT (n = 8), RYGBP (n = 8), SGIT (n = 8), and Sham-operated pigs (n = 8). From day 0 postsurgery to 130, pigs were weighed monthly to determine live weight and weight gain was calculated for each month postsurgery until day 130. Food intake in a metabolic weight basis was calculated by measuring ad libitum food intake at day 130. Swine were fitted into metabolic crates to determine digestibility coefficients of dry matter, protein, fat, fiber, ash, energy, calcium, and phosphorous from day 130. A one-way ANOVA and Student-Newman-Keuls were used to detect differences in weight, food intake, and digestibility coefficients. Digestibility values for dry matter, fiber, phosphorus, and energy showed no differences among groups (P > 0.05). However, significant differences (P ≤ 0.05) were encountered among groups for fat, protein, ash, and calcium digestibilities. The RYGBP procedure, when applied to the pig model, significantly reduced calcium, fat, and ash digestibility, which did not occur with SGIT or IT procedure, when compared with Sham-operated animals.

Abstract
OBJECTIVE To obtain a pooled risk estimate on the long-term impact of anaemia and related nutritional deficiencies in patients receiving Roux-en-Y gastric bypass (RYGB) surgery. DESIGN Systematic review and meta-analysis. DATA SOURCES MEDLINE, EMBASE and Cochrane databases were searched to identify English reports published before 16 May 2014. ELIGIBILITY CRITERIA Articles with case numbers >100, follow-up period >12 months, and complete data from both before and after surgery were selected. Outcomes of interest were changes in baseline measurements of proportion of patients with anaemia, by haemoglobin, haematocrit, ferritin, iron, vitamin B12 and folate levels. DATA COLLECTION AND ANALYSIS Two reviewers independently reviewed data and selected six prospective and nine retrospective studies with a total of 5909 patients. A random effect model with inverse variance weighting was used to calculate summary estimates of outcomes at 6, 12, 24 and 36 months postoperatively. RESULTS Proportion of patients with anaemia was 12.2% at baseline, which, respectively, increased to 20.9% and 25.9% at 12 and 24 months follow-up, consistent with decreases in haemoglobin and haematocrit levels. Although the serum iron level did not change substantially after surgery, the frequency of patients with ferritin deficiency increased from 7.9% at baseline to 13.4% and 23.0% at 12 and 24 months, respectively, postoperation. Vitamin B12 deficiency increased from 2.3% at baseline to 6.5% at 12 months after surgery in those subjects receiving RYGB. There was no obvious increase in folate deficiency. CONCLUSIONS RYGB surgery is associated with an increased risk of anaemia and deficiencies of iron and vitamin B12, but not folate. Ferritin is more sensitive when serum iron level is within normal range.

Abstract
Bariatric surgery is an effective intervention in the treatment of obesity, but lifestyle and diet should be monitored after this procedure to ensure success. The Bariatric Food Pyramid was created basing on long-term nutritional care that proposes a standard of healthy living and eating habits considering gastric capacity and specific nutritional needs. The purpose of the current study is to evaluate the life habits and diet quality of patients who have undergone bariatric surgery (who have been recovering for at least 6 months) based on the specific food pyramid. Retrospective data analysis was performed using medical records of patients who had been followed for at least 6 months after bariatric surgery. The following data were collected from patient records: age, gender, education level (years), BMI (preoperative and postoperative), percentage of excess weight loss (EWL) relative to the time of surgery, frequency of physical activity, use of nutritional supplements, usual dietary intake history, and fluid intake. Results were analyzed using descriptive statistics. We evaluated 172 patient records. In this study, there was a low prevalence of physical activity, use of vitamin-mineral supplements, and water intake. There also was low consumption of protein, fruit, vegetables, and vegetable oils. In addition, intake of carbohydrates, sugars, and fats were higher than the recommendations established by the pyramid. The results indicate that patients who have undergone bariatric surgery have an inadequate diet according to food evaluation with the specific pyramid. In the long term, this may lead to weight gain and vitamin and mineral deficiencies.

Abstract
Germline CDH1 mutations confer a high lifetime risk of developing diffuse gastric (DGC) and lobular breast cancer (LBC). A multidisciplinary workshop was organised to discuss genetic testing, surgery, surveillance strategies, pathology reporting and the patient's perspective on multiple aspects, including diet post gastrectomy. The updated guidelines include revised CDH1 testing criteria (taking into account first-degree and second-degree relatives): (1) families with two or more patients with gastric cancer at any age, one confirmed DGC; (2) individuals with DGC before the age of 40 and (3) families with diagnoses of both DGC and LBC (one diagnosis before the age of 50). Additionally, CDH1 testing could be considered in patients with bilateral or familial LBC before the age of 50, patients with DGC and cleft lip/palate, and those with precursor lesions for signet ring cell carcinoma. Given the high mortality associated with invasive disease, prophylactic total gastrectomy at a centre of expertise is advised for individuals with pathogenic CDH1 mutations. Breast cancer surveillance with annual breast MRI starting at age 30 for women with a CDH1 mutation is recommended. Standardised endoscopic surveillance in experienced centres is recommended for those opting not to have gastrectomy at the current time, those with CDH1 variants of uncertain significance and those that fulfil hereditary DGC criteria without germline CDH1 mutations. Expert histopathological confirmation of (early) signet ring cell carcinoma is recommended. The impact of gastrectomy and mastectomy should not be underestimated; these can have severe consequences on a psychological, physiological and metabolic level. Nutritional problems should be carefully monitored.

Abstract
Background: Poor adherence to post-bariatric surgery aftercare continues to challenge surgical practices. The objective of this study was to identify factors that predict poor aftercare attendance among patients who underwent Roux-en-Y Gastric Bypass (RYGB) surgery. Method: A retrospective medical chart review of patients who underwent RYGB from 2002 to 2011 was conducted. Patients with four visits or more in the first 2 years (>50%) were categorized as "acceptable follow-up" and with ≤50% as "poor follow-up." Demographics, presurgical body mass index (BMI), and comorbidities were compared using multivariate analysis. Results: Out of 2,658 patients, 1,092 (41.1%) had acceptable follow-up. Preoperative factors that predicted acceptable follow-up included female gender (odds ratio [OR] 1.41 [95% confidence interval (CI) 1.15-1.72]), older age (OR 1.03 [95% CI 1.03-1.04]), higher BMI at surgery (OR 1.02 [95% CI 1.01-1.03]), and Hispanic ethnicity (OR 1.40 [95% CI 1.15-1.72]). Conversely, presence of diabetes mellitus (OR 0.58 [95% CI 0.39-0.88]), hypertension (OR 0.53 [95% CI 0.39-0.72]), and obstructive sleep apnea (OR 0.39 [95% CI 0.26-0.57]) predicted less adherence to RYGB aftercare. Conclusion: These findings suggest RYGB patients' age, gender, ethnicity, preoperative BMI, and certain comorbidities should be considered to maximize postoperative aftercare attendance.

Abstract
Bariatric surgery is the most effective therapeutic option for obese patients; however, it carries substantial risks, including procedure-related complications, malabsorption, and hormonal disturbance. Recent years have seen an increase in the bariatric surgeries performed utilizing either an independent or a combination of restrictive and malabsorptive procedures. We review some complications of bariatric procedures more specifically, hypoglycemia and osteoporosis, the recommended preoperative assessment and then regular follow up, and the therapeutic options. Surgeon, internist, and the patient must be aware of the multiple risks of this kind of surgery and the needed assessment and follow up.

Abstract
Bariatric patients may present for psychiatric evaluation due to exacerbation of preexisting psychiatric disorders, new onset psychiatric disorders and/or neuropsychiatric complications associated with abnormal nutritional and metabolic states following the surgical procedure. These neuropsychiatric complications can be insidious, and clinical manifestations may vary, possibly due to the individual central nervous system (CNS) vulnerability to nutritional decline. Lack of awareness of these complications and their symptoms can result in delays in diagnosis and treatment. Identifying and correcting underlying pathophysiologic processes that lead to such neuropsychiatric syndromes can be challenging. We report a case of a patient who developed a protracted course of mood and cognitive disorder after gastric bypass surgery, which illustrates some of the complexities encountered in diagnosing and managing these patients.

Abstract
Introduction Nutrition counseling is important for veterans undergoing gastric bypass surgery. The aim of this study was to explore the relationship between the number of nutrition visits a patient attended and change in body mass index (BMI) after gastric bypass surgery for the veteran population. Methods A retrospective study examined veterans (N = 79) who underwent Roux-en-Y gastric bypass surgery from June 2004 through July 2010. Spearman’s correlation and multivariate regression analysis were used to analyze data. Results A significant correlation was found between the number of postoperative nutrition visits and the change in postsurgery BMI at 2 years (Spearman’s ρ = 0.21; P = .017). After adjusting for age, sex, and race, the association between postsurgery nutrition visits and BMI change persisted (β = 0.255; 95% confidence interval, 0.015–0.581; P = .039). Conclusion Veterans with more nutrition visits following Roux-en-Y gastric bypass surgery experienced greater declines in BMI. This finding underscores the importance of the dietitian on the bariatric surgery team.

Abstract
Obesity is a worldwide epidemic associated with diseases such as diabetes mellitus and cardiovascular disease. Current methods for weight loss are not very effective, particularly for those with morbid obesity. Surgical therapy may be recommended for those with a BMI≥40kg/m(2), or BMI≥35kg/m(2) with co-morbidities. This therapy can produce significant weight loss and improve/resolve co-morbidities including hypertension and hyperlipidemia. Yet successes may be tempered by adverse effects on trace element absorption and status. A PubMed literature search identified studies from January 1980 to February 2013 for inclusion in a meta-analysis. Publications that contained keywords 'bariatric surgery or gastric bypass,' 'trace element or mineral or zinc or iron or copper or iodine or manganese', and 'absorption or status or rate or level' were identified. Inclusion criteria were human markers that reflect changes in trace element status before and after bariatric surgery. The meta-analysis found a decrease in blood copper, zinc, hemoglobin, as well as an increase in iron, regardless of the type of surgery. The pooled effect sizes and 95% confidence intervals were 0.17 and -0.09 to 0.43 for plasma/serum iron (p=0.20); -0.49 and -0.67 to -0.31 for blood hemoglobin (p=0.00); -0.47 and -0.90 to -0.05 for plasma/serum copper (p=0.03); -0.77 and -1.20 to -0.35 for plasma/serum zinc (p=0.00). Differences in levels of these minerals pre- and post-surgery may have been influenced by the time period after surgery, a pre-existing deficiency, type and dose of vitamin-mineral supplements, and malabsorption due to elimination of parts of the gastrointestinal tract.

Abstract
BACKGROUND Obesity is one of the health issues that is recently worldwide increasing, as well as in France. Variety of procedures of bariatric surgery have been developed over the past decade and are performed for morbid obesity hence. The demand of plastic surgery increased for body contouring and reshaping after dramatic weight loss, in which the abdominoplasty is considered as one of the most common procedures. The purpose of this study is to clarify the differences between the post-bariatric patients and others, and their influence on the occurrence of complications following abdominoplasty. PATIENTS AND METHODS Retrospective study involving a group of post-abdominoplasty patients collected from the same center between January 2000 and December 2010. RESULTS Among 238 reviewed patients' files; 114 of them are post-bariatric patients, and 124 are non-bariatric patients. Several differences were found between these two groups of patients including the maximum BMI, BMI at the time of surgery, the rates of cardiovascular risk factors, and a longer operative time in the post-bariatric group. The complication rate in these patients was significantly higher (55.3% against 26.6%) with mainly healing problems. Major maximum weight, obesity at the time of surgery, long operative time and postoperative drainage system are all considered as risk factors, which carry high rate of complications. CONCLUSION It appears that abdominoplasty in post-bariatric patients requires specific care because of particularities inherent in this population.

Abstract
PURPOSE Bone regulation system may be affected after bariatric surgeries, but procedures impact differently to bone mineral density (BMD) and measures restraining bone loss are frequently neglected until clinical consequences become manifest. This is a systematic review aimed to elucidate whether BMD loss is comparable after different bariatric surgeries. MATERIALS AND METHODS A search of morbid obese adults, undergone to bariatric surgery, with BMD measured by dual-energy X-ray absorptiometry at baseline and after surgery studies was performed in several databases. Studies were assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement and COCHRANE Risk of Bias tool. The random model was selected for meta-analysis; heterogeneity was analyzed with T(2), inconsistency (I(2) > 50%) and Chi(2) (p < 0.10). Level of evidence and strength of recommendations were summarized using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE System). RESULTS Twelve studies met the selection criteria. After one year, reduction in total BMD in patients with mixed surgical procedures was significant: -0.03 g/cm(2) (CI 95% 0.00 to -0.06, p < 0.05). BMD was reduced by -0.12 g/cm(2) (CI 95% -0.10 to -0.15, p < 0.001) in the hip, -0.07 g/cm(2) (CI 95% -0.03 to -0.11, p < 0.001) in the column, and -0.03 g/cm(2) (IC 95% -0.02 to -0.04, p < 0.001) in the forearm, but not in restrictive surgeries. Studies included showed high heterogeneity and low quality of evidence. CONCLUSIONS Patients undergone to mixed bariatric surgery had significant higher BMD deterioration as demonstrated in this review, suggesting that more attention for preventing fractures is required.

Abstract
BACKGROUND Bariatric surgery is an important method for treatment of morbid obesity. It is known that significant nutritional deficiencies might occur after surgery, such as, calorie-protein malnutrition, iron deficiency anemia, and lack of vitamin B12, thiamine, and folic acid. OBJECTIVE The objective of our study was to validate a computerized intelligent decision support system that suggests nutritional diagnoses of patients submitted to bariatric surgery. METHODS There were fifteen clinical cases that were developed and sent to three dietitians in order to evaluate and define a nutritional diagnosis. After this step, the cases were sent to four bariatric surgery expert dietitians who were aiming to collaborate on a gold standard. The nutritional diagnosis was to be defined individually, and any disagreements were solved through a consensus. The final result was used as the gold standard. Bayesian networks were used to implement the system, and database training was done with Shell Netica. For the system validation, a similar answer rate was calculated, as well as the specificity and sensibility. Receiver operating characteristic (ROC) curves were projected to each nutritional diagnosis. RESULTS Among the four experts, the rate of similar answers found was 80% (48/60) to 93% (56/60), depending on the nutritional diagnosis. The rate of similar answers of the system, compared to the gold standard, was 100% (60/60). The system sensibility and specificity were 95.0%. The ROC curves projection showed that the system was able to represent the expert knowledge (gold standard), and to help them in their daily tasks. CONCLUSIONS The system that was developed was validated to be used by health care professionals for decision-making support in their nutritional diagnosis of patients submitted to bariatric surgery.
