Abstract
Background: After a diet- or surgery induced weight loss almost 1/3 of lost weight consists of fat free mass (FFM) if carried out without additional therapy. Exercise training and a sufficient supply of protein, calcium and vitamin D is recommended to reduce the loss of FFM. Objective: To investigate the effect of exercise training, protein, calcium, and vitamin D supplementation on the preservation of FFM during non-surgical and surgical weight loss and of the combination of all interventions together in adults with obesity. Methods: A systematic review was performed with a pairwise meta-analysis and an exploratory network meta-analysis according to the PRISMA statement. Results: Thirty studies were included in the quantitative analysis. The pairwise meta-analysis showed for Exercise Training + High Protein vs. High Protein a moderate and statistically significant effect size (SMD 0.45; 95% CI 0.04 to 0.86), for Exercise Training + High Protein vs. Exercise Training a high but statistically not significant effect size (SMD 0.91; 95% CI -0.59 to 2.41) and for Exercise Training alone vs. Control a moderate but statistically not significant effect size (SMD 0.67; 95% CI -0.25 to 1.60). In the exploratory network meta-analysis three interventions showed statistically significant effect sizes compared to Control and all of them included the treatment Exercise Training. Conclusions: Results underline the importance of exercise training and a sufficient protein intake to preserve FFM during weight loss in adults with obesity. The effect of calcium and vitamin D supplementation remains controversial and further research are needed.

The Need and Safety of Mineral Supplementation in Adults with Obesity Post Bariatric Surgery-Sleeve Gastrectomy (SG). Obes Surg 2021; 31:4502-4510. [PMID: 34345960 PMCID: PMC8458182 DOI: 10.1007/s11695-021-05639-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Revised: 07/27/2021] [Accepted: 07/27/2021] [Indexed: 10/25/2022]
Abstract
PURPOSE Most of the research indicated that daily dietary intake of minerals in SG patients was lower than the current recommendations. The aim of the study was to assess the need and safety of a mineral supplementation practice in adults with obesity, at 3, 6, and 9 months post bariatric surgery-sleeve gastrectomy (SG). METHODS The study included 24 women and 6 men. Based on a 4-day food record questionnaire, mineral and calorie intake was calculated at 3, 6, and 9 months after bariatric surgery (SG). Furthermore, an interview on supplement intake was also conducted. RESULTS It was found that in both men and women, there was a dietary intake deficiency of calcium (97% of respondents), potassium (97%), magnesium (83%), sodium (60%), and zinc (53%). In women, the deficiencies also included iron (50%) and copper (29%). Only 72% of the patients took dietary supplements. The applied supplementation did not adjust for the required intake of calcium in all of the patients, as well as the intake of magnesium in the male patients. Low intake of sodium and potassium were not supplemented and should be corrected by diet modification. The patients did not require supplementation of phosphorus or manganese, while male patients did not require iron or copper supplementation. The dietary and/or supplemental intake of minerals did not exceed the tolerable upper intake level (UL). CONCLUSION The results of the study confirm the need to implement personalized mineral supplementation for bariatric surgery patients.

Abstract
PURPOSE OF REVIEW Bariatric surgery is an effective treatment option for severe and complex obesity; however, those who undergo such surgery need access to nutritional monitoring and vitamin and mineral supplementation to avoid the development of nutritional deficiencies. RECENT FINDINGS The British Obesity and Metabolic Surgery Society and the American Society for Metabolic and Bariatric Surgery have recently updated their recommendations on preoperative and postoperative nutritional monitoring and supplementation. There is a growing interest in the more malabsorptive procedures that are associated with an increased risk of nutritional deficiencies. Nutritional monitoring and prevention of nutritional deficiencies are discussed.Long-term follow-up that includes annual nutritional monitoring and access to a dietetic annual review is recommended; however, in the United Kingdom, many bariatric surgery centres are only commissioned to provide 2 years of follow-up, after which care is transferred to the general practitioner. Consideration should be given to developing shared care models for aftercare and also for the aftercare of malabsorptive procedures to remain with specialist centres. SUMMARY Bariatric surgery is a safe and effective treatment option for severe and complex obesity. It is essential that patients have access to lifelong nutritional monitoring adjustment of vitamin and mineral supplements to prevent nutritional issues.

Abstract
In order to develop evidence-based recommendations and expert consensus for nutrition management of patients undergoing bariatric surgery and postoperative follow-up, we conducted a systematic literature search using PRISMA methodology plus critical appraisal following the SIGN and AGREE-II procedures. The results were discussed among all members of the GARIN group, and all members answered a Likert scale questionnaire to assess the degree of support for every recommendation. Patients undergoing bariatric surgery should be screened preoperatively for some micronutrient deficiencies and treated accordingly. A VLCD (Very Low-Calorie Diet) should be used for 4–8 weeks prior to surgery. Postoperatively, a liquid diet should be maintained for a month, followed by a semi-solid diet also for one month. Protein requirements (1–1.5 g/kg) should be estimated using adjusted weight. Systematic use of specific multivitamin supplements is encouraged. Calcium citrate and vitamin D supplements should be used at higher doses than are currently recommended. The use of proton-pump inhibitors should be individualised, and vitamin B12 and iron should be supplemented in case of deficit. All patients, especially pregnant women, teenagers, and elderly patients require a multidisciplinary approach and specialised follow-up. These recommendations and suggestions regarding nutrition management when undergoing bariatric surgery and postoperative follow-up have direct clinical applicability.

Abstract
IMPORTANCE Few studies have described the longitudinal trajectories of serum levels of micronutrients whose deficiencies are associated with serious sequelae following bariatric procedures, such as anemia, osteoporotic fractures, and neuropathies. Furthermore, previous studies comparing laparoscopic sleeve gastrectomy (LSG) vs Roux-en-Y gastric bypass (LRYGB) or one-anastomosis gastric bypass (OAGB) procedures may have been limited by selection and confounding biases. OBJECTIVE To appraise the spectrum and temporal course of micronutrient deficiencies associated with bone metabolism and erythropoiesis after LSG vs OAGB or LRYGB procedures, using the propensity score as a balancing score. DESIGN, SETTING, AND PARTICIPANTS This prospective, longitudinal comparative effectiveness study was conducted at a high-volume bariatric unit in Singapore from September 1, 2008, to November 30, 2017, with a cutoff date for analysis of September 2018. Patients who underwent adjustable gastric banding, biliopancreatic diversion procedures, and intragastric balloon procedures were excluded. All other patients who underwent bariatric procedures were included. Data were analyzed from September 23 to 30, 2018. MAIN OUTCOMES AND MEASURES Serial assessment of 13 biochemical parameters at 12 time points for up to 5 years after bariatric procedure. Inverse probability-of-treatment weights were used to obtain estimates of the mean associations of variables assessed with the bariatric surgical interventions. Longitudinal trajectories were analyzed using mixed-effects generalized linear models to apportion the temporal variation of serum micronutrients into fixed-effects and random-effects components. RESULTS A total of 688 patients were included in this study, of whom 499 underwent LSG (mean [SD] age, 41.5 [11.3] years; 318 [63.7%] women) and 189 underwent OAGB or LRYGB (mean [SD] age, 48.6 [9.4] years; 112 [59.3%] women). There were no differences during follow-up among patients who underwent LSG vs those who underwent OAGB or LRYGB in intact parathyroid hormone levels (mean difference, 7.05 [95% CI, -28.67 to 42.77] pg/mL; P = .70), serum 25-hydroxyvitamin D levels (mean difference, -0.72 [95% CI, -1.56 to 0.12] ng/mL; P = .09), or phosphate levels (mean difference, 0.006 [95% CI, -0.052 to 0.064] mg/dL; P = .83). Hemoglobin levels were a mean 0.63 (95% CI, 0.41 to 0.85) g/dL higher among patients who underwent LSG compared with those who underwent OAGB or LRYGB (P < .001), despite no differences in iron concentration levels (mean difference, 1.50 [95% CI, -1.39 to 4.39] µg/dL; P = .31), total iron-binding capacity (mean difference, 4.36 [95% CI, -5.25 to 13.98] µg/dL; P = .37), or ferritin levels (mean difference, 3.0 [95% CI, -13.0 to 18.9] ng/mL; P = .71). Compared with patients who underwent LSG procedures, patients who underwent OAGB or LRYGB had higher folate levels (mean difference, 2.376 [95% CI, 1.716 to 3.036] ng/mL; P < .001) but lower serum magnesium levels (mean difference, -0.25 [95% CI, -0.35 to -0.16] mg/dL; P < .001) and zinc levels (mean difference, -7.58 [95% CI, -9.92 to -5.24] µg/dL; P < .001). CONCLUSIONS AND RELEVANCE These findings suggest that LSG vs OAGB or LRYGB procedures have differential associations with various micronutrient and metabolic parameters. These differences should be recognized in guidelines for postbariatric nutritional surveillance and prevention.

Abstract
BACKGROUND Adherence to post-bariatric surgery nutritional supplements can be poor and is associated with higher micronutrient deficiency rates. There is currently no available study specifically seeking patients' perspectives on the reasons behind poor adherence and how to address it. METHODS Bariatric surgery patients living in the UK were invited to take part in an anonymous survey on SurveyMonkey®. RESULTS A total of 529 patients (92.61% females, mean age 47.7 years) took part. Most of these patients had undergone either a Roux-en-Y gastric bypass (63.0%) or sleeve gastrectomy (24.0%). Most of the patients were in full-time (49.0%, n = 260/529) or part-time (15.7%, n = 83/529) employment. Approximately 54.0% (n = 287/529) of the respondents reported having trouble taking all their supplements. Males were significantly more likely to report complete compliance. The most important reported reason for poor compliance was difficulty in remembering (45.6%), followed by too many tablets (16.4%), side effects (14.3%), cost (11.5%), non-prescribing by GP (10.8%), bad taste (10.1%), and not feeling the need to take (9.4%). Patients suggested reducing the number of tablets (41.8%), patient education (25.7%), GP education (24.0%), reducing the cost (18.5%), and more information from a healthcare provider (12.5%) or a pharmacist (5.2%) to improve the compliance. CONCLUSIONS This study is the first attempt to understand patient perspectives on poor adherence to post-bariatric surgery nutritional recommendation. Patients offered a number of explanations and also provided with suggestions on how to improve it.

Abstract
Iron deficiency and anaemia after metabolic surgery, potentially modifiable nutritional complications, are becoming an increasing cause for concern as prevalence increases with time and there is limited evidence supporting the effectiveness of the current guidelines for prophylactic oral iron supplementation and treatment for deficiency. Abnormalities in iron nutrition predisposing to deficiency are common in severely obese patients, and the low-grade systemic inflammation, also common to these patients, reduces the effectiveness of oral iron supplementation. The surgical procedures result in alterations of foregut anatomy and physiology, which limit iron absorptive capacity and daily food intake. These alterations and the limited effects of oral iron supplementation explain the high prevalence of postoperative iron deficiency and anaemia. This review outlines current mechanisms concerning the pathogenesis of disordered iron nutrition in patients with severe obesity, current gaps in knowledge, and opportunities for quality improvement.

Abstract
BACKGROUND Nutritional deficiencies are common after bariatric surgery, but data are scarce after sleeve gastrectomy (SG) at long term. METHODS We performed a prospective nutritional status evaluation before and at 2 and 5 years after SG in morbid obese patients receiving mulvitamin and mineral supplementation at a Spanish university hospital. One hundred seventy-six patients (49.3 ± 9.1 years and 46.7 ± 7.4 kg/m2) were evaluated; 51 of them were followed during 5 years. Anthropometric, compliance supplementation intake, and micronutrient evaluation were performed. RESULTS Baseline concentrations were below normal values for 25(OH) vitamin D (73%), folic acid (16.5%), cobalamin (6.9%), pyridoxine (12%), thiamine (3.4%), and copper (0.5%). Anemia was found in 23%. In 49% of the subjects, at least one micronutrient deficiency was found at 2 years after SG. Vitamin D deficiency persisted at 2 and 5 years higher than 30% of patients. Frequencies of deficiencies for folic acid, B12, B6, and B1 vitamins decreased significantly after 2 years with normalization at 5 years. Copper deficiency increased between 1 and 2 years and it persisted at 5 years after SG. Vitamin supplementation compliance decreased progressively from the first year after surgery (94.8 to 81% at 2 years and to 53% 5 years after surgery). CONCLUSIONS Vitamin D deficiency is the most prevalent long-term nutritional deficiency after SG. About half of patients show some micronutrient deficiency at medium long term, despite supplementation. A proactive follow-up is required to ensure a personalized and adequate supplementation in all surgically treated obese patients including those in which SG has been performed.

Abstract
OBJECTIVE To investigate whether bariatric surgery increases the risk of fracture. DESIGN Retrospective nested case-control study. SETTING Patients who underwent bariatric surgery in the province of Quebec, Canada, between 2001 and 2014, selected using healthcare administrative databases. PARTICIPANTS 12 676 patients who underwent bariatric surgery, age and sex matched with 38 028 obese and 126 760 non-obese controls. MAIN OUTCOME MEASURES Incidence and sites of fracture in patients who had undergone bariatric surgery compared with obese and non-obese controls. Fracture risk was also compared before and after surgery (index date) within each group and by type of surgery from 2006 to 2014. Multivariate conditional Poisson regression models were adjusted for fracture history, number of comorbidities, sociomaterial deprivation, and area of residence. RESULTS Before surgery, patients undergoing bariatric surgery (9169 (72.3%) women; mean age 42 (SD 11) years) were more likely to fracture (1326; 10.5%) than were obese (3065; 8.1%) or non-obese (8329; 6.6%) controls. A mean of 4.4 years after surgery, bariatric patients were more susceptible to fracture (514; 4.1%) than were obese (1013; 2.7%) and non-obese (3008; 2.4%) controls. Postoperative adjusted fracture risk was higher in the bariatric group than in the obese (relative risk 1.38, 95% confidence interval 1.23 to 1.55) and non-obese (1.44, 1.29 to 1.59) groups. Before surgery, the risk of distal lower limb fracture was higher, upper limb fracture risk was lower, and risk of clinical spine, hip, femur, or pelvic fractures was similar in the bariatric and obese groups compared with the non-obese group. After surgery, risk of distal lower limb fracture decreased (relative risk 0.66, 0.56 to 0.78), whereas risk of upper limb (1.64, 1.40 to 1.93), clinical spine (1.78, 1.08 to 2.93), pelvic, hip, or femur (2.52, 1.78 to 3.59) fractures increased. The increase in risk of fracture reached significance only for biliopancreatic diversion. CONCLUSIONS Patients undergoing bariatric surgery were more likely to have fractures than were obese or non-obese controls, and this risk remained higher after surgery. Fracture risk was site specific, changing from a pattern associated with obesity to a pattern typical of osteoporosis after surgery. Only biliopancreatic diversion was clearly associated with fracture risk; however, results for Roux-en-Y gastric bypass and sleeve gastrectomy remain inconclusive. Fracture risk assessment and management should be part of bariatric care.

Abstract
INTRODUCTION Bariatric surgery is the most effective therapeutic option to reduce weight in morbidly obese individuals, but it results in a number of mineral and vitamin deficiencies. Clinical Practice Guidelines (CPGs) attempt to balance those benefits and harms to provide guidance to physicians and patients. OBJECTIVES We compare and evaluate the quality of the evidence and of the development process of current CPGs that provide recommendations on vitamin D replacement in patients undergoing bariatric surgery, using a validated tool. METHODS We searched 4 databases, with no time restriction, to identify relevant and current CPGs. Two reviewers assessed eligibility and abstracted data, in duplicate. They evaluated the quality of CPGs development process using the Appraisal of Guidelines, Research, and Evaluation II (AGREE II) tool that consists of 6 domains. A content expert verified those assessments. RESULTS We identified 3 eligible CPGs: (1) the Endocrine Society (ES) guidelines (2010); (2) the American Association of Clinical Endocrinologists (AACE), The Obesity Society (TOS), and the American Society for Metabolic & Bariatric Surgery (ASMBS) guidelines (update 2013); and (3) the Interdisciplinary European (IE) guidelines on Metabolic and Bariatric Surgery (latest update 2014). The ES and the AACE/TOS/ASMBS guidelines recommended high doses of vitamin D, varying from 3000IU daily to 50,000IU 1-3 times weekly. Vitamin D doses were not mentioned in the IE guidelines. The recommendations were based on a low quality of evidence, if any, or limited to a single high quality trial, for some outcomes. In terms of quality, only the IE guidelines described their search methodology but none of the CPGs provided details on evidence selection and appraisal. None of the three CPGs rigorously assessed the preferences of the target population, resource implications, and the applicability of these guidelines. According to the AGREE II tool, we rated the ES guidelines as average in quality, and the other two as low in quality. CONCLUSION Current CPGs recommendations on vitamin D supplementation in bariatric surgery differ between societies. They do not fulfill criteria for optimal guideline development, in part possibly due to limited resources, and are based on expert opinion. Thus, the pressing need for high quality randomized trials to inform CPGs, to be developed based on recommended standards.
