Abstract
PURPOSE Bariatric surgery (BS), an effective treatment for severe obesity and its comorbidities, may result in micronutrient and vitamin deficiencies. This monocentric prospective observational study aimed at evaluating the efficacy of a specifically designed vitamin/mineral formula (Bariatrifast, BIOITALIA S.r.l., Italy) for preventing and treating micronutrient deficiencies in patients submitted to BS. METHODS Twenty patients with severe obesity (mean weight and BMI: 123.5 kg (range 88-174) and 43.3 kg/m2 (range 37-54) respectively) underwent BS (10 vertical sleeve gastrectomy VSG, 10 Roux-en-Y gastric bypass, RYGB). The mean age was 49.9 years (range 27-68). After a presurgical visit (V0), follow-up visits were performed at 1, 3, 6 and 12 months after surgery (V1-V4). Recorded data included weight, height and BMI. A complete blood count, measurement of ferritin, folic acid, vitamin B12, ionized calcium, 25 OH vitamin D, parathyroid hormone (PTH) were obtained. Following BS, patients started the daily oral multivitamin and mineral supplement. RESULTS All patients achieved a significant weight loss (mean - 34.7 ± 11.8 kg). No deficiencies of various vitamins/micronutrients were detected during the entire study period. The serum concentrations of vitamin B12, 25-OH Vitamin D and folic acid increased over the follow-up period compared with V0 (mean increase 243 ng/L, 23 µg /L, 8 µg/L, respectively). Compared to RYGB, patients who underwent sleeve gastrectomy showed higher levels of 25-OH vitamin D at V2, V3 and V4 (all p < 0.05), and higher levels of Vitamin B12 and folic acid at V4 (p < 0.05 and p < 0.005, respectively). No adverse events were reported. CONCLUSION Following VSG or RYGB, Bariatrifast administration was associated with normal values of essential micronutrients, and it was well-tolerated without evidence of gastrointestinal side effects. Clinical Trial Registration ClinicalTrials.gov, identifiers NCT06152965.

Abstract
OBJECTIVE This systematic review and meta-analysis study aimed to estimate changes in blood nutrient concentrations and nutrient deficiencies in adolescents following bariatric surgery. METHODS We searched PubMed, Scopus, and the Web of Science to find studies published between January 2000 and August 2023. Observational studies reporting the mean blood concentration of nutrients before and after bariatric surgery or the proportion of nutrient deficiencies after the surgery in healthy adolescents were selected. RESULTS Fifteen studies were included. Gastric bypass and sleeve gastrostomy were the most common types of surgery. Vitamin D, iron, or ferritin, vitamin B12, calcium, and folic acid were the most studied nutrients, respectively. Other nutrients examined in the studies included zinc, phosphorus, and albumin. The serum ferritin increased by 21 mcg/L (95% CI = 10.0, 32.0 mcg/L) after the surgery, but there were no significant alterations in other nutrients. The postoperative prevalence of low albumin, ferritin, vitamin D, and vitamin B12 levels was 10%, 49%, 41%, and 20%, respectively. Also, 23% had an iron deficiency, and 10% had a calcium deficiency after bariatric surgery. CONCLUSIONS The serum ferritin level increased following bariatric surgery in adolescents. Vitamin D and ferritin deficiencies were estimated to be present in more than one-third of adolescents after the surgery.

Abstract
NAFLD or non-alcoholic fatty liver disease is one of the complications of obesity and diabetes, the prevalence of which is increasing. The causes of the pathology and its development towards its severe form, NASH or non-alcoholic steatohepatitis, are multiple and still poorly understood. Many different pharmacological classes are being tested in clinical trials to treat NASH, but no pharmaceutical treatment is currently on the market. Moreover, the diagnosis of certainty is only possible by liver biopsy and histological analysis, an invasive procedure with high risk for the patient. It is therefore necessary to better understand the natural history of the disease in order to identify therapeutic targets, but also to identify markers for the diagnosis and monitoring of the disease using a blood sample, which will allow an improvement in patient management.

Long-Term Outcomes of Revisional Malabsorptive Bariatric Surgery: Do the Benefits Outweigh the Risk? Obes Surg 2022; 32:1822-1830. [PMID: 35352269 PMCID: PMC9072481 DOI: 10.1007/s11695-022-06019-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2021] [Revised: 03/14/2022] [Accepted: 03/16/2022] [Indexed: 11/22/2022]
Abstract
Purpose To evaluate the long-term outcomes of revisional malabsorptive bariatric surgery. Materials and Methods Malabsorptive bariatric procedures are increasingly performed in the revisional setting. We collated and analysed prospectively recorded data for all patients who underwent a revisional Biliopancreatic diversion + / − duodenal switch (BPD + / − DS) over a 17-year period. Results We identified 102 patients who underwent a revisional BPD + / − DS. Median follow-up was 7 years (range 1–17). There were 21 (20.6%) patients permanently lost to follow-up at a median of 5 years postoperatively. Mean total weight loss since the revisional procedure of 22.7% (SD 13.4), 20.1% (SD 10.5) and 17.6% (SD 5.5) was recorded at 5, 10 and 15 years respectively. At the time of revisional surgery, 23 (22.5%) patients had diabetes and 16 (15.7%) had hypercholesterolaemia with remission of these occurring in 20 (87%) and 7 (44%) patients respectively. Nutritional deficiencies occurred in 82 (80.4%) patients, with 10 (9.8%) patients having severe deficiencies requiring periods of parenteral nutrition. Seven (6.9%) patients required limb lengthening or reversal procedures. There were 16 (15.7%) patients who experienced a complication within 30 days, including 3 (2.9%) anastomotic leaks. Surgery was required in 42 (41.2%) patients for late complications. Conclusion Revisional malabsorptive bariatric surgery induces significant long-term weight loss and comorbidity resolution. High rates of temporary and permanent attrition from follow-up are of major concern, given the high prevalence of nutritional deficiencies. These data question the long-term safety of malabsorptive bariatric procedures due to the inability to ensure compliance with nutritional supplementation and long-term follow-up requirements.

Abstract
Purpose To describe a case of central retinal vein occlusion (CRVO) in a young adult found to have elevated homocysteine after bariatric surgery and to review risk factors for CRVO in younger patients. Observations An 18-year-old female presented with a CRVO and severe cystoid macular edema (CME). She was normotensive, not on medications, and without known heritable hypercoagulable disease. Her medical history was notable for bariatric surgery and subsequently she was found to have nutritional deficiency, anemia, and elevated homocysteine. Her elevated homocysteine may have induced a hypercoaguable state that predisposed her to developing a CRVO. Treatment with bevacizumab dramatically improved her macular edema and visual acuity. Nutritional supplementation was initiated. Conclusions Elevated homocysteine in the setting of nutritional deficiency from prior bariatric surgery may cause a hypercoaguable state and is a potential risk factor for CRVO. Importance With the increasing prevalence of obesity and bariatric surgery, it is important to consider associated nutrient deficiency as a potential cause of induced hypercoagulability and increased risk for CRVO. Identification of these at-risk patients is especially important given this condition is easily treatable and may be present in younger individuals. To the best of our knowledge, this is the first reported case of a CRVO with elevated homocysteine in the setting of nutrient deficiencies from laparoscopic sleeve gastrectomy.

Micronutrient status in bariatric surgery patients receiving postoperative supplementation per guidelines: Insights from a systematic review and meta-analysis of longitudinal studies. Obes Rev 2021; 22:e13249. [PMID: 33938111 DOI: 10.1111/obr.13249] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Revised: 03/10/2021] [Accepted: 03/10/2021] [Indexed: 01/20/2023]
Abstract
The micronutrient status and optimal monitoring schedule after bariatric surgery have not been sufficiently assessed. This systematic review and meta-analysis investigated the longitudinal changes in micronutrient status after bariatric surgery. PubMed, EMBASE, and Cochrane Library were searched for articles that measured preoperative and postoperative serum micronutrient levels in patients undergoing Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Among guideline-adherent studies, the longitudinal changes in micronutrient status were investigated using weighted mean difference (WMD) using a random-effects model. Among the 82 included studies, the guideline adherence rates for micronutrient supplementation after bariatric surgery did not exceed 20%. In patients supplemented per guidelines, vitamin A significantly decreased after RYGB by -7.54 (95% confidence interval [CI], -10.16 to -4.92) μg/dl at 12-23 months, vitamin E decreased after RYGB by -2.35 (95% CI, -3.65 to -1.05) μg/dl at ≥24 months, and ferritin by -54.93 (95% CI, -77.19 to -32.67] μg/L at ≥24 months after SG, compared with baseline, with moderate level of evidence. Significant decreases in micronutrient levels at certain follow-up intervals in studies with supplementation per guidelines need to be considered to establish a post-bariatric micronutrient monitoring schedule for timely detection and management of micronutrient deficiencies.

Abstract
BACKGROUND AND AIMS Today, Sleeve gastrectomy (SG) has recently become the most common bariatric procedure among various bariatric surgical procedures due to its advantages. The aim of this study is to investigate nutritional status, body composition and biochemical parameters following SG. METHODS This was a prospective study, the subjects were patients who underwent SG at a special obesity clinic in İstanbul, Turkey, between 01.05.2017 and 01.11.2017. The mean body mass index (BMI) of the participants was 42.15 ± 4.84 kg/m2 for men and 41.44 ± 4.34 kg/m2 for women, preoperatively. Nutritional status, some anthropometric measurements and blood sampling were taken at each visit. Data were collected and analyzed for the present study at the following periods: pre-operation (pre-op), 1 month, 3 months and 6 months after surgery. RESULTS A total of 47 SG patients (20 men, 27 women) were evaluated. The mean BMI was 30.23 ± 3.56 kg/m2 for men and 30.35 ± 4.36 kg/m2 for women after 6 months and the amount of excess weight loss (EWL) increased in the 3 months (p < .001). Mean energy, fiber, vitamin A, vitamin C, vitamin B1, niacin, vitamin B12, folate, calcium, magnesium, iron, zinc, phosphorus and iodine were above the Dietary Reference Intake (DRI) recommendations. A significant association was found between protein intake and fat free mass loss in both genders after SG at 6 months (p < .05). CONCLUSION Nutrition deficiencies are common for patients after SG. Therefore, it is important to routinely monitor these patients with a professional team.

Abstract
The purpose of this study was to conduct a literature review to examine micronutrient deficiencies in laparoscopic sleeve gastrectomy. We conducted a literature review using PubMed and Cochrane databases to examine micronutrient deficiencies in SG patients in order to identify trends and find consistency in recommendations. Seventeen articles were identified that met the defined criteria. Iron, vitamin B12 and vitamin D were the primary micronutrients evaluated. Results demonstrate the need for consistent iron and B12 supplementation, in addition to a multivitamin, while vitamin D supplementation may not be necessary. Additional prospective studies to establish a clearer picture of micronutrient deficiencies post-SG are needed.

Abstract
BACKGROUND Bariatric surgery is the most effective therapy for severe obesity. It reduces gastric capacity and may modify regulation of appetite, satiety, insulin, and other physiologic processes, resulting in weight loss. OBJECTIVE Long-term data on postsurgical nutrient intake are lacking. SETTING The Longitudinal Assessment of Bariatric Surgery-3 psychosocial study. METHODS Reported dietary intake was assessed in a subset of participants (n = 72) of the Longitudinal Assessment of Bariatric Surgery-3 psychosocial study who underwent Roux-en-Y gastric bypass surgery. Two 24-hour diet recalls at presurgery and annual assessments over 7 years were obtained. Reported diets were evaluated for energy, macro- and micronutrient intake, and assessed for adequacy by comparison to the dietary reference intakes. RESULTS After surgery, reported intake of total energy, and all macronutrients were significantly reduced. At least a quarter of participants reported protein intake below the recommended dietary allowance. Over half of participants reported intake of several vitamins (C, D, A, E, thiamin, folate) and minerals (zinc, calcium) below recommended levels over 7 years. Compared with presurgery, reported energy intake was reduced over 7 years. This study was registered at ClinicalTrials.gov as NCT02495142. CONCLUSIONS The reduction in energy resulted in intakes below the dietary reference intakes for many micronutrients among the majority of participants and below the recommended dietary allowance for protein in a substantial subgroup. These data support continued long-term nutrition education, monitoring, and supplementation.

Abstract
We aim to assess the prevalence of vitamin D deficiency (VDD) in patients scheduled for bariatric surgery (BS), and to identify factors that might be associated with VDD. We conducted a cross-sectional observational study involving all consecutive patients scheduled for BS from 2017 to 2019. The exclusion criteria were missing data for vitamin D levels, intake of vitamin D supplements in the 3 months prior to serum vitamin D determination, and renal insufficiency. A total of 206 patients (mean age and body mass index [BMI] of 34.9 ± 10.7 years, and 44.3 ± 6.99 kg/m2, respectively) met the inclusion criteria and were enrolled for data analysis. VDD (<19.9 ng/mL), severe VDD (<10 ng/mL), and vitamin D insufficiency (20-29.9 ng/mL) were present in 68.8 %, 12.5 %, and 31.2 % of patients, respectively. A significant inverse correlation was found between vitamin D levels and initial BMI, parathyroid hormone, and homeostatic model assessment of insulin resistance (r = -0.280, p < 0.05; r = -0.407, p = 0.038; r = -0.445, p = 0.005), respectively. VDD was significantly more prevalent in patients with higher BMI [-0.413 ± 0.12, CI95 % (-0.659; -0.167), p = 0.006], whereas no significant association between hypertension [-1.005 ± 1.65, CI95 % (-4.338; 2.326), p = 0.001], and diabetes type 2 (T2D) [-0.44 ± 2.20, CI95 % (-4.876; 3.986), p = 0.841] was found. We observed significant association between female sex and levels of vitamin D [6.69 ± 2.31, CI95 % (2.06; 11.33), p = 0.006]. The present study shows that in patients scheduled for BS, VDD deficiency is common and was associated with higher BMI, and female sex.

Abstract
BACKGROUND Selenium is an essential element that plays a vital role in maintaining human health and its deficiency can lead to cardiovascular and hypothyroidism complications. In this context, the main concern is about morbidly obese patients who undergo a Roux-en-Y Gastric Bypass (RYGB). Although RYGB leads to 60-70% excess weight loss, micronutrient deficiencies are common after this procedure and can be problematic if not promptly detected. This review will therefore examine the evidence regarding selenium deficiency in RYGB patients, as well its nutritional treatment methods. METHODS There were a total of 6 studies regarding RYGB and selenium deficiency, which were retrieved from PUBMED and SCOPUS electronic databases, ranging from 2006 to 2017. CONCLUSION Selenium deficiency was observed before and after RYGB. Lifelong supplementation and regular patient monitoring after surgery are recommended.

Abstract
OBJECTIVES Obesity is a chronic disease with high prevalence in Saudi population. Bariatric surgery is an effective method for significant weight reduction. However, various types of nutritional deficiencies occur after weight loss surgery which increase the risk of anaemia. In this study, we aimed to determine the incidence of anaemia after bariatric surgery. METHOD A retrospective descriptive study was conducted with 70 patients of both genders aged over 16 years. These patients underwent bariatric surgery between February 2016 and March 2018 and had completed 6 months or more of post-surgery follow-up. Anthropometric and laboratory data were obtained before and after surgery at standard time intervals. All patients were on postoperative vitamin supplements. RESULTS Of the total study patients, 41 were women (58.57%) and 29 were men (41.42%) with a median age of 38.5 years (range, 16-65). The median follow-up time was 8 months (6-24 months). Postoperatively, 16 patients (22.9%) developed anaemia, and interestingly, all of them were women (39%). Fifteen of these sixteen patients (93.8%) had microcytic anaemia. Two of those sixteen patients (12.5%) had Roux-en-Y gastric bypass, while fourteen (87.5%) had sleeve gastrectomy. CONCLUSION Anaemia and its related nutritional deficiencies are a common complication after bariatric surgery which exerts a major impact on health, particularly in women. Hence, a strict post-operative follow-up and appropriate supplementation are recommended to combat anaemia and its related nutritional deficiencies.

Role of Functional Biomarkers to Identify Early Vitamin B12 Deficiency in Patients with Sleeve Gastrectomy: A Cross-Sectional Study. ACTA ACUST UNITED AC 2020; 56:medicina56030142. [PMID: 32245061 PMCID: PMC7143905 DOI: 10.3390/medicina56030142] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 02/20/2020] [Accepted: 02/24/2020] [Indexed: 12/19/2022]
Abstract
Background and objectives: Although laparoscopic sleeve gastrectomy (LSG) is effective for obesity management, postoperative vitamin B12 (B12) deficiency is of major concern. In this cross-sectional study, we assessed the levels of B12 and its related functional biomarkers, namely, total homocysteine (tHcy), methylmalonic acid (MMA), folate, methylcitric acid (MCA), and hemoglobin (Hb), in one-year postoperative LSG patients and matched controls. Materials and Methods: Plasma B12, tHcy, MMA, folate, and MCA were measured in matched controls (n = 66) and patients (n = 71) using validated liquid chromatography-tandem mass spectrometry techniques and protocols in the United Arab Emirates (UAE). Results: The median B12 concentration in patients (177 pmol/L) was significantly lower (p < 0.001) than in the controls (334.7 pmol/L). The tHcy and MMA levels were significantly increased (p < 0.001 and p = 0.011, respectively) and folate levels were significantly decreased (p = 0.001) in the LSG patients compared to the controls. Interestingly, no significant difference in MCA levels were observed between the two groups. The levels of tHcy and MMA were concomitantly increased with the decreased folate levels in postoperative LSG patients when compared with the controls. The Hb levels were significantly lower in males and females in the patient group compared with those in the control group, respectively (p = 0.005 and p = 0.043). Conclusions: This is the first report of serum levels of B12 and its functional biomarkers in postoperative LSG patients among a local population from the UAE. Our findings revealed significant alterations of the B12 biomarkers, total B12, MMA, and tHcy in one-year postoperative LSG patients.

Abstract
The purpose of this study is to evaluate the food intolerance after banded Roux-en-Y gastric bypass (RYGB), correlating the data of food ingestion. METHODS: This is an observational prospective study, which evaluated the individuals before and 3, 6, and 12 months after banded RYGB. We performed an anthropometric evaluation and an assessment of the habitual food ingestion and applied a food tolerance questionnaire. RESULTS: The study group was comprised of 75 individuals, 89% of them female, with a percentual weight loss of 29.73 ± 6.79%. The observed results were that food intolerance increased over time and 1 year after surgery, only 2.7% reported to ingest any type of food, while the greatest difficulty was related to red meat (80%). Regarding vomits, after surgery, this proportion significantly increased after 3, 6, and 12 months. Preoperatively, the mean protein ingestion was 98 g, which decreased to 50 g after 3 and 6 months and to 51 g after 12 months. As a conclusion, food intolerance significantly increased following banded RYGB, leading to a crescent dissatisfaction regarding food and an increase in the vomits frequency.

Abstract
In recent decades there has been an alarming increase in the prevalence of obesity in patients with type 1 diabetes leading to the development of insulin resistance and cardiometabolic complications, with mechanisms poorly clarified. While bariatric surgery has long been considered an effective treatment option for patients with type 2 diabetes, the evidence regarding its benefits on weight loss and the prevention of complications in T1DM patients is scarce, with controversial outcomes. Bariatric surgery has been associated with a significant reduction in daily insulin requirement, along with a considerable reduction in body mass index, results which were sustained in the long term. Furthermore, studies suggest that bariatric surgery in type 1 diabetes results in the improvement of comorbidities related to obesity including hypertension and dyslipidemia. However, regarding glycemic control, the reduction of mean glycosylated hemoglobin was modest or statistically insignificant in most studies. The reasons for these results are yet to be elucidated; possible explanations include preservation of beta cell mass and increased residual function post-surgery, improvement in insulin action, altered GLP-1 function, timing of surgery, and association with residual islet cell mass. A number of concerns regarding safety issues have arisen due to the reporting of peri-operative and post-operative adverse events. The most significant complications are metabolic and include diabetic ketoacidosis, severe hypoglycemia and glucose fluctuations. Further prospective clinical studies are required to provide evidence for the effect of bariatric surgery on T1DM patients. The results may offer a better knowledge for the selection of people living with diabetes who will benefit more from a metabolic surgery.

Abstract
BACKGROUND Nutritional deficiencies are a well-recognized long-term complication following bariatric surgery. The presence of preoperative deficiencies has been shown to be predictive of postoperative deficiencies. OBJECTIVE The aim of the study was to investigate the prevalence of micronutrient deficiency in a large sample of patients with severe obesity preoperatively, and to determine whether such deficiencies may be related to patient's sex, body mass index, or ethnic subgroup. DESIGN A cross-sectional study of data collected at the time of the preoperative evaluation. PARTICIPANTS/SETTING Data were collected during the preoperative evaluation of 872 bariatric surgery candidates in a university hospital in Israel between 2011 and 2018. The patients were 72.9% women, with a mean age of 37.9±12.1 years and mean body mass index of 42.4±4.7 MAIN OUTCOME MEASURES: Nutritional deficiencies according to blood assays. Data on anthropometrics, comorbidities, and demographic characteristics was also collected. STATISTICAL ANALYSES Baseline differences between patient subgroups were analyzed using independent-samples t test, analysis of variance, or χ2 test. RESULTS Deficiencies of vitamin D, iron, folate, vitamin B-12, elevated parathyroid hormone and low transferrin saturation were present in 75.2%, 42.6%, 28.5%, 8.5%, 35.5%, and 70% of patients, respectively. Nutritional deficiencies were significantly more common among women compared with men for iron (45.9% vs 33.5%; P=0.002), low transferrin saturation (77.7% vs 44.6%; P<0.001), vitamin D (77.5% vs 69.2%; P=0.019) and elevated parathyroid hormone level (39.5% vs 22.9%; P=0.002). Iron, transferrin saturation, and vitamin D deficiencies were more prevalent in Arab patients compared with Jewish patients: 59.6% vs 36%; P<0.001, 80.2% vs 62.8%; P=0.003, and 85.1% vs 71.6%; P<0.001, respectively. Vitamin D and iron deficiency were more common among higher body mass index subgroups (P=0.004 and P=0.040, respectively). CONCLUSIONS The results indicate a high prevalence of nutritional deficiencies, mainly of iron and vitamin D in bariatric surgery candidates. Patients at higher risk for nutritional deficiencies include those with higher body mass index, women, and Arabs.

Abstract
INTRODUCTION Obesity is considered a public health problem and has led to advancements in bariatric surgery. Laparoscopic sleeve gastrectomy (LSG) had become the most performed procedure worldwide; however, its consequences on nutritional status in the short and long term are of concern. METHODS A retrospective analysis of medical records and bariatric database of patients who underwent LSG from October 2008-September 2015 at Al-Amiri Hospital, Kuwait, was performed. Data regarding nutritional status along with demographic data were collected over a 5-year follow-up period. RESULTS One thousand seven hundred ninety-three patients comprising of 74% females and 26% males were included. The greatest % total body weight loss (%TBWL) was at 18 months post-LSG (33%), corresponding to a % excess weight loss (%EWL) of 73.8%. With regard to nutritional status, vitamin B1 showed a significant drop at 3-5 years post-op in comparison to pre-op value, but stayed within the normal range throughout the study. Red blood cells count, hemoglobin, and hematocrit also showed a significant drop starting from 6 months post-op until the fifth year of follow-up. On the other hand, vitamins B6 and B12 showed a significant increase at 6 months post-op and decreased afterwards, but did not reach pre-op values. Vitamin D also showed a significant increase throughout the study period from deficient value at the pre-op time, but remained insufficient. Albumin, transferrin, folate, ferritin, iron, and vitamin B2 showed no significant changes at 5 years post-LSG compared to pre-op values. CONCLUSION Little is known about the nutritional status and optimal nutritional care plan post-LSG, especially in the longer term. Nutritional deficiencies were prevalent prior and post-LSG. Some of the nutritional parameters improved and even reached the abnormal high level post-LSG. These observations highlight the importance of pre- and post-operative nutritional assessment and tailored supplementation to ensure optimal nutritional status.

Abstract
SETTING The physiological and anatomical changes that occur as a consequence of bariatric surgery result in macro- and micro-nutritional deficiencies, especially iron deficiency. The reported incidence of iron deficiency and associated anemia after bariatric surgery varies widely across studies. OBJECTIVES The aim of this systematic review is to quantify the impact of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on the incidence of iron deficiency. METHODS Databases including Ovid Medline, Ovid Embase, Helthstar, Scopus, Cochrane (CDSR), LILACS, and ClinicalKey were searched for original articles with additional snowballing search. Search terms included Obesity, nutrient deficiency, iron deficiency, iron deficiency anemia, bariatric surgery, Roux-en-Y gastric bypass, and sleeve gastrectomy. Original articles reporting the incidence of iron deficiency and anemia pre- and post-RYGB and SG from January 2000 to January 2015 with minimum 1-year follow-up were selected. Data extraction from selected studies was based on protocol-defined criteria. RESULTS There were 1133 articles screened and 20 studies were included in the final analysis. The overall incidence of iron deficiency was 15.2% pre-operatively and 16.6% post-operatively. When analyzed by procedure, the incidence of iron deficiency was 12.9% pre-RYGB versus 24.5% post-RYGB and 36.6% pre-SG versus 12.4% post-SG. The incidence of iron deficiency-related anemia was 16.7% post-RYGB and 1.6% post-SG. Risk factors for iron deficiency were premenopausal females, duration of follow-up, and pre-operative iron deficiency. Prophylactic iron supplementation was reported in 16 studies and 2 studies provided therapeutic iron supplementation only for iron-deficient patients. Iron dosage varied from 7 to 80 mg daily across studies. CONCLUSION Iron deficiency is frequent in people with obesity and may be exacerbated by bariatric surgery, especially RYGB. Further investigation is warranted to determine appropriate iron supplementation dosages following bariatric surgery. Careful nutritional surveillance is important, especially for premenopausal females and those with pre-existing iron deficiency.

Abstract
Bariatric surgeries are considered the only effective way of weight loss therapy in morbidly obese patients, i.e. body mass index ≥ 35. However, micronutrient deficiencies and malnutrition are common after most bariatric procedures and thus, pre- and postoperative nutritional assessment and corrections are advised. The present review is presented in an effort to describe in some detail about prevalence, and mechanisms of macro- and micronutrient deficiencies in obese and post-bariatric surgery individuals. We also aimed to summarize the data on screening and supplementation of macro- and micronutrients before and after bariatric surgeries.

Abstract
The American Society for Metabolic and Bariatric Surgery Pediatric Committee updated their evidence-based guidelines published in 2012, performing a comprehensive literature search (2009-2017) with 1387 articles and other supporting evidence through February 2018. The significant increase in data supporting the use of metabolic and bariatric surgery (MBS) in adolescents since 2012 strengthens these guidelines from prior reports. Obesity is recognized as a disease; treatment of severe obesity requires a life-long multidisciplinary approach with combinations of lifestyle changes, nutrition, medications, and MBS. We recommend using modern definitions of severe obesity in children with the Centers for Disease Control and Prevention age- and sex-matched growth charts defining class II obesity as 120% of the 95th percentile and class III obesity as 140% of the 95th percentile. Adolescents with class II obesity and a co-morbidity (listed in the guidelines), or with class III obesity should be considered for MBS. Adolescents with cognitive disabilities, a history of mental illness or eating disorders that are treated, immature bone growth, or low Tanner stage should not be denied treatment. MBS is safe and effective in adolescents; given the higher risk of adult obesity that develops in childhood, MBS should not be withheld from adolescents when severe co-morbidities, such as depressed health-related quality of life score, type 2 diabetes, obstructive sleep apnea, and nonalcoholic steatohepatitis exist. Early intervention can reduce the risk of persistent obesity as well as end organ damage from long standing co-morbidities.

Abstract
Copper is a crucial micronutrient needed by animals and humans for proper organ function and metabolic processes such as hemoglobin synthesis, as a neurotransmitter, for iron oxidation, cellular respiration, and antioxidant defense peptide amidation, and in the formation of pigments and connective tissue. Multiple factors, either hereditary or acquired, contribute to the increase in copper deficiency seen clinically over the past decades. The uptake of dietary copper into intestinal cells is via the Ctr1 transporter, located at the apical membrane aspect of intestinal cells and in most tissues. Copper is excreted from enterocytes into the blood via the Cu-ATPase, ATP7A, by trafficking the transporter towards the basolateral membrane. Zinc is another important micronutrient in animals and humans. Although zinc absorption may occur by direct interaction with the Ctr1 transporter, its absorption is slightly different. Copper deficiency affects physiologic systems such as bone marrow hematopoiesis, optic nerve function, and the nervous system in general. Detailed pathophysiology and its related diseases are explained in this manuscript. Diagnosis is made by measuring serum copper, serum ceruloplasmin, and 24-h urine copper levels. Copper deficiency anemia is treated with oral or intravenous copper replacement in the form of copper gluconate, copper sulfate, or copper chloride. Hematological manifestations are fully reversible with copper supplementation over a 4- to 12-week period. However, neurological manifestations are only partially reversible with copper supplementation.

Abstract
Total esophagogastric dissociation (TED) is used to treat gastroesophageal reflux (GER) after failed fundoplication in neurologically impaired patients. It is now performed for some otherwise healthy patients with severe GER. In this procedure, the gastrointestinal tract is reconstructed in a non-physiological way with a Roux-en-Y esophagojejunal anastomosis and jejuno-jejunostomy. Although TED eliminates almost all GER, some patients experience late complications. In this review, we investigated the long-term outcomes after TED to determine the best indications. In total, 147 neurologically impaired patients and 28 neurologically normal patients were identified. The total rate of complications requiring re-operation was 17.2% in neurologically impaired patients and 32.1% in normal patients, both higher than the rates associated with fundoplication. Although most authors added pyloroplasty when there was a concern of gastric emptying, this sometimes caused bile reflux. Nutritional and metabolic complications, including dumping syndrome and chronic digestive malabsorption, were also reported to occur after TED. TED is an option for the treatment of neurologically impaired patients with recurrent GER after fundoplication or who are at a high risk of recurrence of GER with fundoplication. However, neurologically normal patients who have the ability to obtain nutrition orally should consider options other than TED, as postoperative complications are frequent.

Abstract
BACKGROUND Few data on bariatric surgery are available regarding obese human immunodeficiency virus (HIV)-infected patients. SETTINGS Antoine Beclere hospital, Clamart, Paris-sud University, France METHODS: Prospective observational follow-up study recruited HIV-infected patients who underwent bariatric surgery from 2009 to 2015. Baseline demographic characteristics, surgery characteristics, perioperative outcomes, changes in weight loss, HIV markers, antiretroviral drug plasma levels are described. RESULTS There were 10 patients followed before and after sleeve gastrectomy: 2 men and 8 women; 50% of African origin; median age, 48.5 years, median time since HIV infection, 7.5 years; median body mass index, 48.5 kg/m2. Of patients, 8 had co-morbidities. All except 2 patients received antiretroviral drugs at the time of surgery with a median CD4 cell count at 709/mm3. There was no death or postoperative infectious complications. The median follow-up was 18 months (range, 15-55). The median postoperative weight loss was 43 kg (range, 17-83). Median percentage of excess weight loss was 82.5% (range, 35-119) at the latest visit after surgery. All co-morbidities were resolutive with weight loss. We observed no significant modification of CD4 cell count before and after surgery. Pharmacokinetics of antiretroviral drugs remains adequate and efficacious. CONCLUSION Our prospective series is the largest one on sleeve gastrectomy procedures performed on obese-treated HIV-infected patients. The sleeve generates good results in weight loss, with no significant impact on HIV infection, and with improvement of obesity-associated co-morbidities. Optimal management of HIV-infected patients with morbid obesity may include classical surgical procedures.

Abstract
Obesity is a constantly growing health problem which reduces quality of life and life expectancy. Bariatric surgery for obesity is taken into account when all other conservative treatment modalities have failed. Comparison of the multidisciplinary programs with bariatric surgery regarding to weight loss showed that substantial and durable weight reduction have been achieved only with bariatric surgical treatments. However, the benefits of weight loss following bariatric procedures are still debated regarding the pro-inflammatory and metabolic profile of obesity.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is being increasingly established as a definitive procedure for weight loss. The mechanism for weight loss in LSG is gastric restriction and neurohormonal changes, but there is deficient information on its nutritional effect. The aim of this prospective study was to assess vitamin and micronutrient deficiencies following LSG (whats and when) in organized follow-up visits. PATIENTS AND METHODS LSG was performed in 112 consecutive patients between June 2010 and December 2013. In all patients, the vitamin and micronutrient deficiencies were corrected before the LSG procedure. Patients were investigated for vitamin and micronutrient concentrations 2, 4, 6, 9, and 12 months after surgery. RESULTS During the study time, 112 patients (65% female) underwent LSG. The mean age was 26 years (range: 20 to 37 y), and the mean preoperative body mass index was 41 (range: 35 to 52). Complications and nutrient deficiencies were observed and analyzed throughout the follow-up period. CONCLUSIONS The appearance of vitamin and nutritional deficiencies after LSG is a common phenomenon. Correction of the deficiencies before surgery, sufficient supplementation immediately after the procedure, and routine long follow-up are important to avoid the serious consequences of the deficiencies.

Abstract
BACKGROUND Data regarding long-term nutritional deficiencies following laparoscopic sleeve gastrectomy (LSG) are scarce. OBJECTIVES To assess the prevalence of nutritional deficiencies and supplement consumption 4 years post-LSG. SETTING Hebrew University, Israel. METHODS Data were collected prospectively from preoperative and 1 and 4 years postoperative including anthropometric parameters, biochemical tests, and supplement intake. RESULTS Data were available for 192, 77, and 27 patients at presurgery and 1 and 4 years post-LSG, respectively. Prevalence of nutritional deficiencies at baseline and 1 and 4 years postsurgery, respectively, were specifically for iron (44%, 41.2%, 28.6%), anemia (11.5%, 20%, 18.5%), folate (46%, 14.3%, 12.5%), vitamin B12 (7.7%, 13.6%, 15.4%), vitamin D (96.2%, 89%, 86%), and elevated parathyroid hormone (PTH) (52%, 15.4%, 60%). Vitamin D levels remained low throughout the whole period. PTH levels were 37.5 pg/mL at 1 year postsurgery and increased to 77.3 pg/mL at 4 years postsurgery (P = .009). Females had higher prevalence of elevated PTH and a tendency for higher rates of anemia, compared with males 4 years postsurgery (80% versus 20%, P = .025; and 28% versus 0%, P = .08, respectively). Of the patients, 92.6% reported taking a multivitamin and 74.1% vitamin D supplements during the first postoperative year, while after 4 years only 37% and 11.1% were still taking these supplements, respectively. CONCLUSION A high rate of nutritional deficiencies is common at 4 years post-LSG along with low adherence to the nutritional supplementation regimen. Long-term nutritional follow-up and supplementation maintenance are crucial for LSG patients. Future studies are needed to clarify the clinical impact of such deficiencies.

Abstract
BACKGROUND Nutritional deficiencies occur after weight loss surgery. Despite knowledge of nutritional risk, there is little uniformity of postoperative vitamin and mineral supplementation. The objective of this study was to evaluate a composite supplement based on the clinical practice guidelines proposed in 2008 regarding vitamin and mineral supplementation after Roux-en-Y gastric bypass. The composite included iron (Fe) and calcium as well. METHODS A retrospective chart review of 309 patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) was evaluated for the development of deficiencies in iron and vitamins A, B1, B12, and D. Patients were instructed to take a custom vitamin and mineral supplement that was based on society-approved guidelines. The clinical practice guidelines were modified to include 1600 international units (IU) of vitamin D3 instead of the recommended 800 IU. RESULTS The compliant patients' deficiency rates were significantly lower than those of the noncompliant patients for iron (p = 0.001), vitamin A (p = 0.01), vitamin B12 (p ≈ 0.02), and vitamin D (p < 0.0001). Women's menstrual status did not significantly influence the development of iron deficiency. CONCLUSIONS Use of a composite based on guidelines proposed by the AACE, TOS, and the ASMBS appears to be effective for preventing iron and vitamins A, B1, B12, and D deficiencies in the LRYGB patients during the first postoperative year. Separation of calcium and Fe does not need to be mandatory. Even with simplification, compliance is far from universal.

Abstract
BACKGROUND The epidemic of obesity is engulfing developed as well as developing countries like India. We present our 7-year experience with laparoscopic sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (RYGB), and mini-gastric bypass (MGB) to determine an effective and safe bariatric and metabolic procedure. METHODS The study is an analysis of a prospectively collected bariatric database of 473 MGBs, 339 LSGs, and 295 RYGBs. RESULTS Mortality rate was 2.1% in LSG, 0.3% in RYGB, and 0% in MGB. Leaks were highest in LSG (1.5%), followed by RYGB (0.3%), and zero in MGB. Bile reflux was seen in <1% in the MGB series. Persistent vomiting was seen only in LSG. Weight regain was 14.2% in LSG, 8.5% in RYGB, but 0% in MGB. Hypoalbuminemia was minimal in LSG, 2.0% in RYGB, and 13.1% in MGB (in earlier patients where bypass was >250 cm). The following resolution of comorbidities: dyslipidemia, type 2 diabetes (T2D), hypertension, and percent excess weight loss (%EWL) was maximum in MGB. GERD was maximum in LSG (9.8%), followed by RYGB (1.7%), and minimal in MGB (0.6%). CONCLUSIONS RYGB and MGB act on the principle of restriction and malabsorption, but MGB superseded RYGB in its technical ease, efficacy, revisibility, and reversibility. Mortality was zero in MGB. %EWL and resolution of comorbidities were highly significant in MGB. Based on this audit, we suggest that MGB is the effective and safe procedure for patients who are compliant in taking their supplements. LSG may be done in non-compliant patients and those ready to accept weight regain.

Abstract
Laparoscopic sleeve gastrectomy (LSG) effectively reduces weight by restricting gastric capacity and altering gut hormones levels. We designed a prospective study to investigate the correlation of serum uric acid (SUA) concentration and weight loss. SUA and body mass index (BMI) were measured preoperatively and on first postoperative month and year in patients who underwent LSG in our department of bariatric surgery. Data on 55 patients were analyzed. Preoperative SUA concentration had a significant positive correlation with percentage of total weight loss (TWL) on first postoperative month (P = 0.001) and year (P = 0.002). SUA concentration on first postoperative month had a positive correlation with percentage of TWL on first postoperative year (P = 0.004). SUA concentration could be used as a predictor of LSG's success and could help in early detection of patients with rapid loss of weight, in order to prevent complications.

Monoacylglycerol-enriched oil increases EPA/DHA delivery to circulatory system in humans with induced lipid malabsorption conditions. J Lipid Res 2016; 57:2208-2216.

Abstract
It was hypothesized that under induced lipid malabsorption/maldigestion conditions, an enriched sn-1(3)-monoacylglycerol (MAG) oil may be a better carrier for n-3 long-chain PUFAs (LC-PUFAs) compared with triacylglycerol (TAG) from fish oil. This monocentric double blinded clinical trial examined the accretion of EPA (500 mg/day) and DHA (300 mg/day) when consumed as TAG or MAG, into the erythrocytes, plasma, and chylomicrons of 45 obese (BMI ≥30 kg/m2 and ≤40 kg/m2) volunteers who were and were not administered Orlistat, an inhibitor of pancreatic lipases. Intake of MAG-enriched oil resulted in higher accretion of LC-PUFAs than with TAG, the concentrations of EPA and DHA in erythrocytes being, respectively, 72 and 24% higher at 21 days (P < 0.001). In addition, MAG increased the plasma concentration of EPA by 56% (P < 0.001) as compared with TAG. In chylomicrons, MAG intake yielded higher levels of EPA with the area under the curve (0-10 h) of EPA being 55% greater (P = 0.012). In conclusion, in obese human subjects with Orlistat-induced lipid maldigestion/malabsorption conditions, LC-PUFA MAG oil increased LC-PUFA levels in erythrocytes, plasma, and chylomicrons to a greater extent than TAG. These results indicate that MAG oil might require minimal enzymatic digestion prior to intestinal uptake and transfer across the epithelial barrier.

Abstract
BACKGROUND Bariatric surgery is currently the treatment of choice for those patients with severe obesity, but the procedure of choice is not clearly established. We describe weight loss and nutritional parameters in severely obese patients after biliopancreatic diversion for 10 years of follow-up. METHODS Patients were followed by the same multidisciplinary team, and data are shown for 10 years. Bariatric Analysis and Reporting Outcome System (BAROS) questionnaire, data regarding the evolution of obesity-related diseases, and nutritional parameters are reported. RESULTS Two hundred ninety-nine patients underwent biliopancreatic diversion, 76.1 % women, initial BMI 50.1 kg/m(2) (7.2). Weight loss was maintained throughout 10 years with EWL% around 65 % and EBMIL% around 70 %. More than 80 % of the patients showed EWL higher than 50 %. Blood pressure, glucose metabolism, and lipid profile clearly improved after surgery. Mean nutritional parameters remained within the normal range during follow-up. Protein malnutrition affected less than 4 % and anemia up to 16 %. Fat-soluble vitamin levels decreased along the time, with vitamin D deficiency in 61.5 % of patients. No significant differences were found either in nutritional parameters or weight loss regarding gastrectomy or gastric preservation, or common limb length longer or shorter than 55 cm CONCLUSIONS Biliopancreatic diversion is an effective surgical procedure in terms of weight loss, quality of life, and evolution of obesity-related diseases. Nutritional deficiencies are less frequent than feared for a malabsorptive procedure, but must be taken into account, especially for fat-soluble vitamins.

Eating patterns and food choice as determinant of weight loss and improvement of metabolic profile after RYGB. Nutrition 2016; 33:125-131. [PMID: 27474230 DOI: 10.1016/j.nut.2016.05.007] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2015] [Revised: 04/14/2016] [Accepted: 05/02/2016] [Indexed: 10/21/2022]
Abstract
OBJECTIVE Significant changes in the preference for different dietary components have been observed after Roux-en-Y gastric bypass (RYGB). The aim of this study was to evaluate the early post-RYGB changes in quality of eating patterns and their relationship to weight loss and metabolic parameters. METHODS The sample was composed of 41 extremely obese individuals undergoing RYGB. Dietary data were collected using a validated food frequency questionnaire in Brazil. A food intake evaluation was conducted with a focus on the frequency of consumption (≥4 times/wk) of markers for healthy eating and markers for unhealthy eating. Furthermore, anthropometric and metabolic markers were collected before surgery and 6 mo post-RYGB. RESULTS Compared with baseline, the postsurgery body mass index was reduced by 12.9 kg/m2, corresponding to an excess weight loss of 63.5%. Blood glucose, insulin, ferritin, cholesterol, low-density lipoprotein-cholesterol, triacylglycerol (TG), and hemoglobin were reduced 6 mo after RYGB (P < 0.05). The consumption frequency of many foods defined as unhealthy decreased after surgery (e.g., from 15.4% to 5.1% for pizza and 18% to 0% for hamburger), and some healthy food increased (e.g., from 0% to 5.1% for fish and from 0% to 25.6% for plain yogurt). There was a decrease in the frequency of individuals who reported consuming fruit and vegetables. Conversely, insulin, glucose, and TG levels were positively associated with intake of chocolates/truffles and ice cream/sundaes. CONCLUSION Participants in the present study appeared to develop a healthier dietary pattern by 6 mo after RYGB. These results show that a healthier dietary pattern is associated with a significant improvement of metabolic profile and weight loss.
