Cao L, Liang S, Yu X, Guan B, Yang Q, Ming WK, Chen Y. Change in Mineral Status After Bariatric Surgery: a Meta-analysis. Obes Surg 2023; 33:3907-3931. [PMID: 37872256 DOI: 10.1007/s11695-023-06888-6] [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: 05/30/2023] [Revised: 10/03/2023] [Accepted: 10/04/2023] [Indexed: 10/25/2023]
Abstract
BACKGROUND The risk of protein and vitamin deficiencies after bariatric surgery has been well studied, but the change in mineral status has not gotten enough attention. This study aimed to perform a meta-analysis regarding the change in mineral levels after bariatric surgery and the prevalence of postoperative mineral deficiency, with subgroup analyses of different surgical procedures, study regions, and follow-up time. METHODS CENTRAL, PubMed, and EMBASE were searched for related articles. Meta-analysis, subgroup analysis, and sensitivity analysis were performed if necessary. RESULTS A total of 107 articles with 47,432 patients were included. The most severe mineral deficiency after bariatric surgery was iron (20.1%), followed by zinc (18.3%), copper (14.4%), chlorine (12.2%), phosphorus (7.5%), and calcium (7.4%). Serum concentrations of potassium, sodium, selenium, manganese, and molybdenum showed no significant change before and after surgery. Subgroup analyses revealed that SG had fewer deficiencies in serum iron, calcium, zinc, magnesium, phosphorus, copper, and selenium than RYGB. OAGB showed a higher incidence of serum iron and zinc deficiencies than RYGB. Studies conducted in different regions also found various mineral statuses after surgery. Studies with follow-up ≥ 5 years had a lower prevalence of zinc, copper, and selenium deficiencies than follow-up < 5 years. CONCLUSION A high deficiency rate of serum iron, zinc, copper, chlorine, phosphorus, and calcium was seen after bariatric surgery. The difference in surgical procedures, study regions, and follow-up time may affect postoperative mineral status; more targeted mineral supplement programs are needed considering these influencing factors.

Abstract
INTRODUCTION Copper is increasingly being recognized as a vital mineral required by both animals and humans. It plays a vital role in many metabolic processes such as cellular respiration, iron oxidation, and hemoglobin synthesis. Copper deficiency, which can be hereditary or acquired, can lead to a wide spectrum of disease processes such as ringed sideroblastic anemia, myelodysplasia, and pancytopenia. Timely identification and management of copper deficiency is necessary to prevent irreversible complications. AREAS COVERED Our study focuses on prevalence, etiology, pathophysiology, complications, and treatment of copper deficiency. EXPERT OPINION Copper deficiency is frequently underrecognized as the cause of anemia, neutropenia, and bone marrow dysplasia. As it is potentially treatable, it should always be kept in the differentials when patients present with neurological and hematological abnormalities.

Abstract
BACKGROUND In the mid-seventies, biliopancreatic diversion became popular as weight-loss surgery procedure. This bariatric procedure combines distal gastric resection and intestinal malabsorption, leading to greater weight loss and improvement of co-morbidities than other bariatric procedures. Nowadays, biliopancreatic diversion has become obsolete due to the high risk of nutritional complications. However, current patients with biliopancreatic diversions are aging. Consequently, geriatricians and general practitioners will encounter them more often and will be faced with the consequences of late complications. CASE PRESENTATION A 74-year old female presented with weakness, recurrent falls, confusion, episodes of irresponsiveness, anorexia and weight loss. Her medical history included osteoporosis, herpes encephalitis 8 years prior and a biliopancreatic diversion (Scopinaro surgery) at age 52. Cerebral imaging showed herpes sequelae without major atrophy. Delirium was diagnosed with underlying nutritional deficiencies. Biochemical screening indicated vitamin A deficiency, vitamin E deficiency, zinc deficiency and severe hypoalbuminemia. While thiamin level and fasting blood glucose were normal. However, postprandial hyperinsulinemic hypoglycemia was observed with concomitant signs of confusion and blurred consciousness. After initiating parenteral nutrition with additional micronutrient supplementation, a marked improvement was observed in cognitive and physical functioning. CONCLUSIONS Long-term effects of biliopancreatic diversion remain relatively underreported in older patients. However, the anatomical and physiological changes of the gastrointestinal tract can contribute to the development of metabolic and nutritional complications that may culminate in cognitive impairment, functional decline and delirium. Therefore, it is warranted to evaluate the presence of metabolic disturbances and nutritional complications in older patients after biliopancreatic diversion.

Abstract
Nutritional care after bariatric surgery is an issue of major importance, especially insofar as risk of deficiency has been extensively described in the literature. Subsequent to the deliberations carried out by a multidisciplinary working group, we are proposing a series of recommendations elaborated using the Delphi-HAS (official French health authority) method, which facilitates the drawing up of best practice and consensus recommendations based on the data of the literature and on expert opinion. The recommendations in this paper pertain to dietary management and physical activity, multivitamin and trace element supplementation and the prevention and treatment of specific deficiencies in vitamins B1, B9, B12, D and calcium, iron, zinc, vitamins A, E and K, dumping syndrome and reactive hypoglycemia.

Abstract
Vitamin E, a fat-soluble vitamin with antioxidant properties, is thought to modulate enzymes involved in signal transduction, affect gene expression, and have immunomodulatory capabilities. Severe vitamin E deficiency is associated with neuronal disorders, impaired immune response, hemolytic anemia, and oxidative-based disorders. Patients who undergo bariatric surgery (BS), especially malabsorptive procedures, are at greater risk of developing fat-soluble vitamin deficiencies. Current data on vitamin E statuses among BS patients are limited. Therefore, this systematic review has summarized the scientific literature on vitamin E and examined its status among patients following different types of BS. Searches of the MEDLINE and Embase databases were performed, followed by hand-searching of reference lists from all relevant papers. Of the 671 initially identified articles, 24 met the inclusion criteria: 1 study on adjustable gastric banding patients (n = 21), 4 studies on sleeve gastrectomy patients (n = 173), 12 studies on Roux-en-Y gastric bypass patients (n = 689) and 12 studies on biliopancreatic diversion with or without duodenal switch (n = 799) or single anastomosis duodeno-ileal bypass with sleeve gastrectomy patients (n = 163). Results suggest that patients who undergo malabsorptive procedures are at higher risk of developing vitamin E deficiency, although clinical manifestations of vitamin E deficits following BS are rarely documented. The optimal dose of vitamin E supplementation required for prevention of deficiency or for treatment following BS has yet to be established. Future observational and intervention studies are needed to bridge the gaps in existing knowledge.

Abstract
Background Bariatric surgery can effectively treat morbid obesity; however, micronutrient deficiencies are common despite recommendations for high-dose supplements. Genetic predisposition to deficiencies underscores necessary identification of high-risk candidates. Personalized nutrition (PN) can be a tool to manage these deficiencies. Methods Medline, PubMed, and Google Scholar were searched. Articles involving genetic testing, micronutrient metabolism, and bariatric surgery were included. Results Studies show associations between genetic variants and micronutrient metabolism. Research demonstrates genetic testing to be a predictor for outcomes among obesity and bariatric surgery populations. There is limited research in bariatric surgery and micronutrient genetic variants. Conclusion Genotype-based PN is becoming feasible to provide an effective treatment of micronutrient deficiencies associated with bariatric surgery. The role of genomic technology in micronutrient recommendations needs further investigation.

Biliopancreatic Diversion in the Surgical Treatment of Morbid Obesity: Long-Term Results and Metabolic Consequences. Obes Surg 2020; 30:4234-4242.

Abstract
PURPOSE In the multidisciplinary therapeutic approach to obesity, bariatric surgery is considered the most effective treatment in weight reduction and the decrease in associated comorbidities. The objective of this work is to describe the long-term clinical and metabolic results in obese patients undergoing biliopancreatic diversion (BPD) according to Scopinaro's technique. MATERIALS AND METHODS Patients undergoing surgery were followed by the same multidisciplinary team in a study period of 15 years (1999-2015). A retrospective study based on a prospective database was designed, where data on the evolution of obesity-related diseases and nutritional parameters were studied. RESULTS Two hundred seventy-seven patients were collected; 75.5% were women. The preoperative body mass index (BMI) decreased from 52.5 kg/m2 to 34.9 kg/m2 10 years after surgery. A resolution or improvement of diabetes has been observed in 85.38% of the patients; a decrease in arterial hypertension and obstructive sleep apnea syndrome were in 65.61% and 89.14%, respectively. Throughout the monitoring of the sample, protein malnutrition increased, from 1.8% after the first year of surgery to 4.5% 10 years after the operation. CONCLUSION Even if Scopinaro's technique is beginning to be replaced by other malabsorptive techniques, it can still be considered as an effective surgical procedure in terms of weight loss, quality of life, and evolution of obesity-related diseases. In order to avoid nutritional deficiencies, the operated patients need a strict follow-up and a supplementation adjusted to the technique.

Abstract
Vitamin K, a fat-soluble vitamin, is involved in blood coagulation, bone mineralization, inhibition of vascular calcification, and regulation of numerous enzyme systems. Patients who undergo bariatric surgery (BS), especially procedures that involve a malabsorptive component, are prone to develop vitamin K deficiency (VKD). The causes of VKD include decreased absorptive surface areas, steatorrhea, bacterial overgrowth, marked reduction of carriers of vitamin K, decrease in vitamin K intake, and modifications of gut microbiota. Data on vitamin K status among BS patients are scarce and the strength of evidence supporting vitamin K supplementation is weak. Thus, this systematic review summarized the scientific literature on vitamin K and examined the status among patients before and after BS, as well as among pregnant women with a history of BS. A MEDLINE/Pubmed and Embase electronic search was performed. After a thorough screening of 204 titles, 19 articles were selected by 2 independent reviewers. Five studies on BS candidates (n = 750), 12 studies after BS (n = 1442), and 4 studies on pregnant woman after BS (n = 83, of them n = 7 from case reports) were included. Results of the current review suggest that patients who undergo major malabsorptive surgeries are at a higher risk of developing VKD and should be better monitored. At this point, it is still unclear whether supplementation of vitamin K is required, and what oral dose or vitamer type should be used to normalize serum levels after different types of bariatric procedures. It should be noted that the current protocols for VKD treatment are still experiential in these patients. It is also unknown at what intervals screening tests for vitamin K should be performed and what assay is most appropriate for screening purposes. Future studies are needed to answer these unresolved issues.

Abstract
BACKGROUND & AIMS The risk allele (G) of rs10830963 in the melatonin receptor 1 B (MTNR1B) gene presents an association with obesity. We study the effect of this SNP on cardiovascular risk factors and weight loss secondary to 2hypocaloric diets. METHODS 361 obese subjects were randomly allocated during 3 months (Diet M - high monounsaturated fat hypocaloric diet vs. Diet P - high polyunsaturated fat hypocaloric diet). Anthropometric parameters, fasting blood glucose, C-reactive protein (CRP), insulin concentration, insulin resistance (HOMA-IR), lipid profile and adipocytokines levels were measured. Genotype of MTNR1B gene polymorphism (rs10830963) was evaluated. RESULTS All anthropometric parameters, systolic blood pressure and leptin levels decreased in all subjects after both diets. This improvement of anthropometric parameters was higher in non G allele carriers than G allele carriers. After dietary intervention with Diet M, (CC vs. CG + GG); total cholesterol (delta: -10.4 ± 2.1mg/dl vs. -6.4 ± 1.2mg/dl: P <.05), LDL-cholesterol (delta:-7.1 ± 0.9mg/dl vs. -2.8 ± 0.8mg/dl: P <.05), insulin (delta:-3.0 ± 0.8 UI/L vs. -2.0 ± 1.0 UI/L: P<.05) and HOMA-IR (delta:-3.4 ± 1.0 units vs. -2.9 ± 0.9 units: P<.05) improved in no G allele carriers. After Diet P, in the group of subjects without G allele CC, insulin levels (delta: -2.9 ± 1.0 UI/L vs. -0.6 ± 0.2 UI/L: P <.05) and HOMA-IR (delta (CC vs. CG + GG): -0.8 ± 0.2 units vs. -0.4 ± 0.3 units: P <.05) decreased, too. CONCLUSIONS Our study detected a relationship of rs10830963 MTNR1B SNP with body weight loss and insulin resistance modification induced by 2different hypocaloric. Only monounsaturated enriched hypocaloric diet and in no-G allele carriers showed a significant effect on lipoproteins.

Abstract
Overweight and obesity are highly prevalent throughout the world and can adversely affect the nutritional status of individuals. Studies have shown that many people with obesity have inadequate intake of iron, calcium, magnesium, zinc, copper, folate and vitamins A and B12, likely as a result of poor diet quality. Nutritional inadequacies or deficiencies may also occur due to altered pharmacokinetics in the individual with obesity and due to interactions in those with overweight or obesity with various pharmaceuticals. However, it has been demonstrated that the adult population in the United States as a whole is deficient in certain micronutrients as a result of the availability and overconsumption of high-calorie, low-nutrient processed foods. Poor nutrition may contribute to the development of certain chronic conditions, such as type 2 diabetes, which is already more prevalent in those with obesity. Clinicians need to be aware of these gaps, particularly in those individuals with obesity who are undergoing bariatric surgery or taking pharmaceutical products long term to facilitate weight loss. Patients with overweight or obesity likely struggle to achieve a balanced diet and may benefit from consultation with a dietitian. Along with providing recommendations for healthy eating and exercise, supplementation with specific micronutrients or multivitamins should be considered for individuals at the highest risk for or with established deficiencies. Further research is needed to understand the factors underlying nutritional inadequacies in individuals with overweight or obesity, as well as the outcomes of treatment strategies employed to address them.

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
Vitamin A is required for important physiological processes, including embryogenesis, vision, cell proliferation and differentiation, immune regulation, and glucose and lipid metabolism. Many of vitamin A’s functions are executed through retinoic acids that activate transcriptional networks controlled by retinoic acid receptors (RARs) and retinoid X receptors (RXRs).The liver plays a central role in vitamin A metabolism: (1) it produces bile supporting efficient intestinal absorption of fat-soluble nutrients like vitamin A; (2) it produces retinol binding protein 4 (RBP4) that distributes vitamin A, as retinol, to peripheral tissues; and (3) it harbors the largest body supply of vitamin A, mostly as retinyl esters, in hepatic stellate cells (HSCs). In times of inadequate dietary intake, the liver maintains stable circulating retinol levels of approximately 2 μmol/L, sufficient to provide the body with this vitamin for months. Liver diseases, in particular those leading to fibrosis and cirrhosis, are associated with impaired vitamin A homeostasis and may lead to vitamin A deficiency. Liver injury triggers HSCs to transdifferentiate to myofibroblasts that produce excessive amounts of extracellular matrix, leading to fibrosis. HSCs lose the retinyl ester stores in this process, ultimately leading to vitamin A deficiency. Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and is a spectrum of conditions ranging from benign hepatic steatosis to non-alcoholic steatohepatitis (NASH); it may progress to cirrhosis and liver cancer. NASH is projected to be the main cause of liver failure in the near future. Retinoic acids are key regulators of glucose and lipid metabolism in the liver and adipose tissue, but it is unknown whether impaired vitamin A homeostasis contributes to or suppresses the development of NAFLD. A genetic variant of patatin-like phospholipase domain-containing 3 (PNPLA3-I148M) is the most prominent heritable factor associated with NAFLD. Interestingly, PNPLA3 harbors retinyl ester hydrolase activity and PNPLA3-I148M is associated with low serum retinol level, but enhanced retinyl esters in the liver of NAFLD patients. Low circulating retinol in NAFLD may therefore not reflect true “vitamin A deficiency”, but rather disturbed vitamin A metabolism. Here, we summarize current knowledge about vitamin A metabolism in NAFLD and its putative role in the progression of liver disease, as well as the therapeutic potential of vitamin A metabolites.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has gained popularity as the leading bariatric procedure for the treatment of morbid obesity. Due to the rising numbers of bariatric surgeries, neurologic complications have become increasingly recognized. Our aim was to examine biochemical and hormonal factors that are associated with neuropathy post-LSG. METHODS Thirty-two patients were included: 16 patients with neuropathy in the neuropathic group (NG) and 16 patients without neuropathy in the control group (CG). Diagnosis was made by a consultant neurologist, and blood samples were taken to examine vitamin deficiencies and hormones involved in neuropathy. RESULTS There was no significant difference between the BMI (p = 0.1) in both groups as well as excess weight loss percentages post-LSG at 12 months (p = 0.6). B12 levels were within normal range, but higher in NG (p = 0.005). Vitamin B1 and B2 levels were significantly lower in NG; p values are 0.000 and 0.031, respectively. Vitamin B6 levels were significantly higher in NG (p = 0.02) and copper levels were lower in NG (p = 0.009). There was no significant difference in GLP-1 response in both groups. CONCLUSION Our data showed post-LSG neuropathy is associated with lower levels of vitamin B1, B2, and copper, plus patients who are older in age. Vitamin B6 was significantly higher in the NG, which is, at toxic levels, associated with neuropathy. No difference in preoperative BMI, excess weight loss percent at 1 year, and GLP-1 levels was found. Larger data is required to validate our results.

Abstract
OBJECTIVE Studies in rodents and humans have indicated that omega-3 polyunsaturated fatty acids (n-3 PUFA) may reduce weight. The aim of this meta-analysis was to evaluate evidence for the efficacy of n-3 PUFA in managing overweight and obesity. METHODS We performed a systematic search of PubMed, Embase, and Cochrane Central Register of Controlled Trials until May 2015. Two reviewers independently determined the eligibility of studies and assessed the reporting quality of included randomized controlled trials (RCTs). RESULTS A total of 11 RCTs involving 617 participants were included in this meta-analysis. Based on the meta-analysis of nine studies, a statistically nonsignificant difference was revealed in weight loss between n-3 PUFA and placebo (p=0.99; weighted mean difference [WMD]: 0.00; 95% confidence interval [CI] -0.42 to 0.43), whereas n-3 PUFA was superior to placebo in reducing serum triglyceride levels (p=0.0007; standard median difference [Std MD]: -0.59; 95% CI -0.93 to -0.25). Based on meta-analysis of seven studies, the analysis of aggregated data showed a significant reduction in waist circumference (p=0.005; WMD: -0.53; 95% CI -0.90 to -0.16). There were no significant differences in body mass index, total serum levels of cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and fasting glucose levels. CONCLUSIONS The evidence from RCTs showed that n-3 PUFA might effectively reduce waist circumference and triglyceride levels in overweight and obese adults, but n-3 PUFA may not effectively reduce body weight. Given the small number and poor quality of RCTs included in the meta-analysis, these results are inconclusive. A large-scale, well-designed RCT is needed to further address this issue.

Abstract
BACKGROUND Obesity is a public health problem that carries global and substantial social and economic burden. Relative to non-surgical interventions, bariatric surgery has the most substantial and lasting impact on weight loss. However, it leads to a number of nutritional deficiencies requiring long term supplementation. OBJECTIVES The aims of this paper are to review 25-hydroxyvitamin D [25(OH)D] status pre and post bariatric surgery, describe the dose response of vitamin D supplementation, and assess the effect of the surgical procedure on 25(OH)D level following supplementation. METHODS We searched Medline, PubMed, the Cochrane Library and EMBASE, for relevant observational studies published in English, from 2000 to April 2015. The identified references were reviewed, in duplicate and independently, by two reviewers. RESULTS We identified 51 eligible observational studies assessing 25(OH)D status pre and/or post bariatric surgery. Mean pre-surgery 25(OH)D level was below 30ng/ml in 29 studies, and 17 of these studies showed mean 25(OH)D levels ≤20ng/ml. Mean 25(OH)D levels remained below 30ng/ml following bariatric surgery, despite various vitamin D replacement regimens, with only few exceptions. The increase in post-operative 25(OH)D levels tended to parallel increments in vitamin D supplementation dose but varied widely across studies. An increase in 25(OH)D level by 9-13ng/ml was achieved when vitamin D deficiency was corrected using vitamin D replacement doses of 1100-7100IU/day, in addition to the usual maintenance equivalent daily dose of 400-2000IU (total equivalent daily dose 1500-9100IU). There was no difference in mean 25(OH)D level following supplementation between malabsorptive/combination procedures and restrictive procedures. CONCLUSION Hypovitaminosisis D persists in obese patients undergoing bariatric surgery, despite various vitamin D supplementation regimens. Further research is needed to determine the optimal vitamin D dose to reach desirable 25(OH)D levels in this population, and to demonstrate whether this dose varies according to the surgical procedure.

Abstract
INTRODUCTION Malabsorptive bariatric procedures, like the biliopancreatic diversion (BPD) and BPD with duodenal switch (BPD/DS), have excellent results in terms of weight loss. However, these malabsorptive techniques are associated with severe malnutrition and vitamin deficiencies. The aim of this study was to evaluate the vitamin and mineral status after BPD and BPD/DS in the long term. METHODS All patients who underwent BPD or BPD/DS were selected and invited for an additional follow-up (FU) visit, including blood sampling for vitamin and mineral levels. RESULTS Forty patients completed the blood sampling with a median FU of 42 (range 12-90) months. At that time, all patients used some kind of supplementation. However, 93 % of all patients were diagnosed with a deficiency. There were no significant differences in mean serum level vitamins and minerals between BPD and BPD/DS. Forty-three per cent of the patients were anaemic, and 40 % had an iron deficiency (ID). High deficiency rates for fat-soluble vitamins were present: vitamin A in 28 %, vitamin D in 60 %, vitamin E in 10 % and vitamin K in 60 % of the patients. Hypervitaminosis was found in 43 % of the patients for vitamin B1 and in 50 % for vitamin B6. CONCLUSION High numbers of vitamin and mineral deficiencies were found after BPD and BPD/DS despite vitamin supplementation. Anaemia, ID and deficiencies for fat-soluble vitamins are frequently diagnosed. Repeated monitoring is necessary to detect deficiencies at an early stage. Taking all of this into consideration, a stringent multivitamin supplementation regimen should be implemented after malabsorptive procedures.

Abstract
BACKGROUND Reduced serum vitamin K levels are frequently observed after biliopancreatic diversion (BPD) and BPD with duodenal switch (BPD/DS). The criteria for treatment are not precisely defined. OBJECTIVES To assess the effects of standardized vitamin K supplementation in patients who develop vitamin K deficiency after BPD or BPD/DS. SETTING Teaching hospital specializing in bariatric surgery. METHODS Serum vitamin K levels, clotting times, and vitamin K-dependent coagulation factors were measured after an overnight fast at baseline and then at 4 days and 1, 4, and 52 weeks after the start of vitamin K supplementation in 10 consecutive patients who had developed severe vitamin K deficiency after BPD or BPD/DS. Vitamin K was administered in a dose of 5 mg/d for 1 week, followed by a maintenance dose of 5 mg once a week. RESULTS At baseline, all patients had serum vitamin K1 levels below the limit of detection, but none reported symptoms of easy bleeding. Minor prolongation of the prothrombin time and minimal decreases of some coagulation factors were observed in a minority of patients. During the first week of vitamin K loading, median serum vitamin K1 levels rose into the high normal range. During maintenance treatment, median vitamin K1 levels settled in the low normal range. CONCLUSION Vitamin K1 deficiency in patients with BPD or BPD/DS is not commonly associated with bleeding or clinically relevant decreases in coagulation factor activity. We hypothesize that vitamin K2 production in the large intestine is usually sufficient to compensate for vitamin K1 deficiency and to maintain total liver vitamin K stores within the range required for (near) normal coagulation factor production.

Abstract
Malabsorptive bariatric surgery is rapidly becoming a major cause of copper deficiency given the increasing prevalence of these procedures for morbid obesity. Acquired copper deficiency can present with clinically significant hematologic and neurological manifestations. Although hematologic manifestations of copper deficiency are rapidly reversible, significant neurological improvement after copper supplementation therapy is unusual and many patients remain debilitated and may only experience, at best, stabilization of the neurological manifestations. Here we present a case of an undiagnosed copper deficiency several years after bariatric gastric bypass surgery, in a patient who concomitantly used zinc-containing denture cream for several years, associated with anemia, neutropenia, myelopathy, respiratory failure, and bilateral optic neuropathy, which caused major vision loss. This patient was also a heterozygote carrier of the 5,10-methylenetetrahydrofolate reductase A1298C gene polymorphism, which may affect copper metabolism. Intravenous copper repletion resulted in rapid correction of hematologic indices. However, neurological manifestations, including vision loss responded only modestly to copper supplementation, despite achieving normal blood copper concentrations. Clinicians should consider copper deficiency in patients at risk, as in this case, as a delayed diagnosis can lead to irreversible disability due to neurological manifestations.

Abstract
Managing the metabolic needs of the patient with obesity is a challenge unto itself without the added demands of accounting for an altered gastrointestinal tract. Nevertheless, with about 200,000 bariatric procedures being performed annually in the United States, clinicians must be prepared to manage the critically ill bariatric surgery patient. This article reviews the recent literature relating to nutrient needs and metabolic support for the bariatric patient. Bariatric patients are at risk for several micronutrient deficiencies, including vitamins D and B₁₂, calcium, and iron; some bariatric procedures affect macronutrient needs as well. Literature on nutrition support guidelines for the bariatric population is limited. However, with an understanding of the anatomical and physiological effects of bariatric surgery, recent guidelines for critically ill patients with obesity can be applied to the bariatric surgery population. The unique needs of the bariatric population, such as susceptibility to micronutrient deficiencies and specialized access routes, must be considered to provide safe and efficacious nutrition support. Further research is necessary to develop specific nutrition support recommendations for the bariatric population.

Abstract
PURPOSE OF REVIEW The increasing utilization of bariatric surgery has been accompanied by an increased incidence and awareness of related neurologic complications. The purpose of this review is to provide up-to-date information on the neurologic complications related to bariatric surgery. RECENT FINDINGS Neurologic complications related to bariatric surgery are predominantly due to nutrient deficiencies. Common early complications include Wernicke encephalopathy due to thiamine deficiency, and late complications include myelopathy or myeloneuropathy due to vitamin B12 or copper deficiency. SUMMARY Early recognition and prompt institution of treatment is essential to prevent long-term disability. Often, life-long supplementation may be required.

Abstract
BACKGROUND Malabsorptive bariatric procedures require multiple vitamin supplements, especially regarding fat-soluble vitamins. The exact amount required to maintain normal serum concentrations is still largely unknown. Based on the initial postoperative prescription, we assessed the number of adjustments and the amount of vitamins/micronutrients to normalize the biological markers 2 years after the biliopancreatic diversion with duodenal switch (BPD/DS). METHODS A total of 112 consecutive patients had a laparoscopic BPD/DS between February 2007 and November 2010 for a body mass index of 53.1±5.9 kg/m² at a private hospital. Complete blood checks with vitamin status were obtained at each of the 3-month interval visits during the 1(st) postoperative year as well as twice during the 2(nd) year. RESULTS Initially, all of the patients were prescribed daily 25,000 International units (IU) of vitamin A, 1000 mg of calcium, multivitamins, and 1900 IU of vitamin D3. Significant adjustments were necessary 3.6±1.1 times during this period. A total of 80% of the patients required added vitamin A, vitamin D, as well as calcium, zinc, and iron. After 2 years,≥20% of patients exhibited vitamin A and iron deficiency with low prealbumin or micropenic anemia. Seventy percent had vitamin D deficiency and 50% secondary hyperparathyroidism. CONCLUSION The initial prescription was insufficient to cover the requirements after BPD/DS. At least 3000 mg of calcium with 7000 IU of vitamin D, 50,000 IU of vitamin A, 40 mg of zinc, and 200 mg of iron must be prescribed to start with. The trend toward a decrease in 25 OH vitamin D and hyperparathyroidism remains difficult to control although it can result from increased bone turnover during the early postoperative period.

Abstract
Lifestyle intervention programmes often produce insufficient weight loss and poor weight loss maintenance. As a result, an increasing number of patients with obesity and related comorbidities undergo bariatric surgery, which includes approaches such as the adjustable gastric band or the 'divided' Roux-en-Y gastric bypass (RYGB). This Review summarizes the current knowledge on nutrient deficiencies that can develop after bariatric surgery and highlights follow-up and treatment options for bariatric surgery patients who develop a micronutrient deficiency. The major macronutrient deficiency after bariatric surgery is protein malnutrition. Deficiencies in micronutrients, which include trace elements, essential minerals, and water-soluble and fat-soluble vitamins, are common before bariatric surgery and often persist postoperatively, despite universal recommendations on multivitamin and mineral supplements. Other disorders, including small intestinal bacterial overgrowth, can promote micronutrient deficiencies, especially in patients with diabetes mellitus. Recognition of the clinical presentations of micronutrient deficiencies is important, both to enable early intervention and to minimize long-term adverse effects. A major clinical concern is the relationship between vitamin D deficiency and the development of metabolic bone diseases, such as osteoporosis or osteomalacia; metabolic bone diseases may explain the increased risk of hip fracture in patients after RYGB. Further studies are required to determine the optimal levels of nutrient supplementation and whether postoperative laboratory monitoring effectively detects nutrient deficiencies. In the absence of such data, clinicians should inquire about and treat symptoms that suggest nutrient deficiencies.

Abstract
BACKGROUND The aim of this study was to compare serum levels of trace elements in morbidly obese female patients seeking bariatric surgery with those of age-matched females with body mass index (BMI) less than or equal to 30. METHODS Blood samples were collected from 66 morbidly obese female patients seeking bariatric surgery prior to undergoing surgery. Blood was collected also from 44 female patients (with BMI less than or equal to 30) prospectively from April 2009 till February 2010. Exclusion criteria in both groups were the presence of any co-morbidities on medication, patients receiving any vitamin supplement or any herbal product intake, smoking, and alcohol consumption. Serum zinc, magnesium, copper, and selenium were measured and compared between the two groups. RESULTS The mean age and BMI for morbidly obese female patients was 28.5 years (21.5-35.5) and 45.26 kg/m(2) (40.3-50.22). The control group had a mean age and BMI of 30.75 years (21.35-40.15) and 25.88 kg/m(2) (22.73-29.03). For morbidly obese patients, the serum level of copper, zinc, selenium, and magnesium was 1,623.84, 698.34, 86.08, and 17,830 μg/l, respectively, compared to 1,633.36, 734.82, 101.14, and 18,260 μg/l for the control group. The serum levels of the trace elements were not statistically significantly different between the two groups except for selenium, which was significantly reduced among morbidly obese female patients (p < 0.0001). CONCLUSIONS Serum selenium level is significantly reduced among morbidly obese female patients seeking bariatric surgery.

Abstract
Obesity and diabetes are increasing in prevalence worldwide. Despite excessive dietary consumption, obese individuals have high rates of micronutrient deficiencies. Deficiencies of specific vitamins and minerals that play important roles in glucose metabolism and insulin signaling pathways may contribute to the development of diabetes in the obese population. This paper reviews the current evidence supporting this hypothesis.

Abstract
INTRODUCTION AND OBJECTIVES The frequency of copper deficiency and clinical manifestations following roux-en-y gastric bypass (RYGB) surgery is not yet clear. Objectives were to determine the prevalence and incidence of copper deficiency in patients who have undergone RYGB. DESIGN AND METHODS We sought to determine the number of RYGB patients undergoing medical and nutritional follow-up visits at the Emory Bariatric Center who experienced copper deficiency and associated hematological and neurological complaints (n=136). Separately, in patients followed longitudinally before and during 6 and 24 months following RYGB surgery, we obtained measures of copper status (n=16). Systemic blood cell counts and measures of copper, zinc and ceruloplasmin were determined using standardized assays in reference laboratories including atomic absorption spectrometry and immunoassays. RESULTS Thirteen patients were identified to have copper deficiency suggesting a prevalence of copper deficiency of 9.6%, and the majority of these had concomitant complications including anemia, leukopenia and various neuro-muscular abnormalities. In the longitudinal study, plasma copper concentrations and ceruloplasmin activity decreased over 6 and 24 months following surgery, respectively (P<0.05), but plasma zinc concentrations did not change. A simultaneous decrease in white blood cells was observed (P<0.05). The incidence of copper deficiency in these subjects was determined to be 18.8%. CONCLUSIONS The prevalence and incidence of copper deficiency following RYGB surgery was determined to be 9.6% and 18.8%, respectively, with many patients experiencing mild-to-moderate symptoms. Given that copper deficiency can lead to serious and irreversible complications if untreated, frequent monitoring of the copper status of RYGB patients is warranted.

Abstract
A growing number of studies suggest a potential link between obesity and altered iron metabolism. The purpose of this systematic review was to examine existing literature on iron status in obese populations. A comprehensive literature search was conducted. Included studies recruited participants ≥ 18 years with a body mass index ≥ 30 kg m(-2) and provided descriptive statistics for haemoglobin or ferritin at a minimum. There were 25 studies meeting all eligibility criteria, of these 10 examined iron status in free-living obese individuals and 15 reported baseline iron biomarkers from bariatric surgery candidates. Non-obese comparison groups were used by 10 (40%) articles. In these, seven obese groups reported higher mean haemoglobin concentration; six reported significantly higher ferritin concentration; and four significantly lower transferrin saturation. Due to insufficient data, it was not possible to make conclusions regarding mean differences for soluble transferrin receptor (sTfR), hepcidin or C-reactive protein. Existing evidence suggests a tendency for higher haemoglobin and ferritin concentration and lower transferrin saturation in obesity. Alternation of iron biomarkers in obese populations may be a result of obesity-related inflammation and/or related comorbidities. Further research incorporating measurement of inflammatory cytokines, sTfR and hepcidin is required to confirm the impact of obesity on iron status.

Abstract
Laparoscopic adjustable gastric banding (LAGB) causes significant weight loss in morbidly obese adults. However, its consequences on nutritional status still remain unclear. There are a few studies determining the nutritional status after LAGB and none have focused on the serum levels of zinc (Zn), copper (Cu), and ceruloplasmin (CP). We aimed to investigate the effects of LAGB surgery on plasma Zn, Cu, and CP levels. Thirty patients with LAGB with morbid obesity were included. Blood samples were collected preooperatively and in the postoperative third month to determine plasma Zn, Cu, and CP levels. The mean preoperative and postoperative body mass indexes (BMI) were 44.9 ± 7.4 kg/m(2) and 44.1 ± 6.5 kg/m(2), respectively. The mean weight loss was 12.9 ± 3.3 kg at the postoperative third month. The postoperative Zn (500 ± 130 ng/ml), Cu (280 ± 80 ng/ml), and CP (23.9 ± 8.8 mg/dl) values were statistically significantly lower than the preooperative Zn (740 ± 230 ng/ml), Cu (370 ± 80 ng/ml) and CP (33.3 ± 15.7 mg/dl) levels (p < 0.05). Decreases in the plasma levels of Zn, Cu, and CP were seen postoperatively following LAGB surgery. The nutritional status of LAGB-applied patients should be monitored and mineral supplementation may be considered.

Abstract
PURPOSE OF REVIEW Obesity is a growing worldwide epidemic. Obese patients are often deficient in micronutrients despite macronutrient excess. Bariatric surgery is an increasingly utilized modality in the treatment of obesity and obesity-related conditions. Bariatric surgery itself may cause or exacerbate micronutrient deficiencies with serious sequelae. This review will focus on perioperative strategies to detect, prevent and treat micronutrient deficiencies in patients undergoing bariatric surgery, and will highlight practical and clinical aspects of these nutritional problems. RECENT FINDINGS Micronutrient deficiency is common in obese patients undergoing bariatric surgery both preoperatively and postoperatively. Bariatric procedures with a malabsorptive component are more likely to result in postoperative micronutrient deficiency. A system-based approach will facilitate clinical suspicion of specific or combined micronutrient deficiencies, leading to appropriate laboratory tests for confirmation. Supplementation by the oral route is always tried first, reserving parenteral administration for specific situations. SUMMARY Clinicians should be aware that micronutrient deficiencies are common in obese patients who may have macronutrient excess. Micronutrient deficiency may exist preoperatively or be caused by bariatric procedures themselves. A systematic and team-based approach will decrease morbidity associated with delays in diagnosis and treatment.

Abstract
BACKGROUND A high prevalence of micronutrient deficiencies in obese subjects has been reported. Bariatric surgery is the most effective long-term treatment of morbid obesity, but this treatment can result in secondary micronutrient deficiencies. The aim of our work was to describe the micronutrient status in obese women before surgery at a university hospital. METHODS We analyzed a consecutive series of 115 women who were referred to our unit for evaluation for bariatric surgery. Their weight, height, body mass index, and waist circumference were measured. The basal hemoglobin, albumin, prealbumin, ferritin, copper, zinc, calcium, phosphorus, parathyroid hormone, and vitamin (A, D, E, K, B12, and folic) blood levels were also determined. RESULTS Deficiencies were found in 6.1% of the subjects for albumin, 21.7% for prealbumin, 2.6% for hemoglobin, and 5.2% for ferritin. In the vitamin analysis, no deficiencies were found in the patients for vitamins A, E, or K, but 71.3% had a moderate deficiency of vitamin D and 26.1% a severe deficiency of vitamin D (<15 ng/mL). In concorndance with the high prevalence of 25-OH vitamin D deficiency, 22.6% of the patients had secondary hyperparathyroidism with intact parathyroid hormone levels >72 pg/mL. Deficiencies were found in 9.5% for vitamin B12, 25.2% for folic acid, 67.8% for copper, and 73.9% for zinc. CONCLUSION Our study has demonstrated a high prevalence of micronutrient deficiencies in morbidly obese women seeking obesity surgery.

Abstract
The vitamin D receptor (VDR) is crucial for virtually all of vitamin D's actions and is thought to be ubiquitously expressed. We hypothesized that disruption of one allele of the VDR gene would impact bone development and would have metabolic consequences. Body composition and bone mass (BMD) in VDR heterozygous (VDR HET) mice were compared to those obtained in male and female VDR KO and WT mice at 8 weeks of age. Male mice were also evaluated at 16 weeks, and bone marrow mesenchymal stem cell (MSC) differentiation was evaluated in VDR female mice. Additionally, female VDR HET and WT mice received intermittent PTH treatment or vehicle (VH) for 4 weeks. BMD was determined at baseline and after treatment. MRI was done in vivo at the end of treatment; μCT and bone histomorphometry were performed after killing the animals. VDR HET male mice had normal skeletal development until 16 weeks of age but showed significantly less gain in fat mass than WT mice. In contrast, female VDR HET mice showed decreased total-body BMD at age 8 weeks but had a normal skeletal response to PTH. MSC differentiation was also impaired in VDR HET female mice. Thus, female VDR HET mice show early impairment in bone acquisition, while male VDR HET mice exhibit a lean phenotype. Our results indicate that the VDR HET mouse is a useful model for studying the metabolic and skeletal impact of decreased vitamin D sensitivity.

Abstract
Normal copper homeostasis is essential for human growth and development. Copper deficiency, caused by genetic mutations, inadequate diet or surgical interventions, may lead to cardiac hypertrophy, poor neuronal myelination, blood vessel abnormalities and impaired immune response. Copper overload is associated with morphological and metabolic changes in tissues and, if untreated, eventual death. Recent reports also indicate that changes in the expression of copper transporters alter the sensitivity of cancer cells to major chemotherapeutic drugs, such as cisplatin, although the mechanism behind this important phenomenon remains unclear. This review summarizes current information on the molecular characteristics of copper transporters CTR1, CTR2, ATP7A and ATP7B, their roles in mammalian copper homeostasis and the physiological consequences of their inactivation. The mechanisms through which copper transporters may influence cell sensitivity to cisplatin are discussed. Regulation of human copper homeostasis has significant therapeutic potential and requires the detailed understanding of copper transport mechanisms.

Abstract
OBJECTIVE The surgical option could represent a valid alternative to medical therapy in some diabetic patients. However, no data are available on long-term effects of metabolic surgery on diabetic complications. We aimed to determine whether patients with newly diagnosed type 2 diabetes who underwent bilio-pancreatic diversion (BPD) had less micro- and macrovascular complications than those who received conventional therapy. RESEARCH DESIGN AND METHODS This was an unblinded, case-controlled trial with 10-years' follow-up, conducted from July 1998 through October 2009 at the Day Hospital of Metabolic Diseases, Catholic University, Rome, Italy. A consecutive sample of 110 obese patients (BMI >35 kg/m(2)) with newly diagnosed type 2 diabetes was enrolled. The study was completed by 50 subjects. The main outcome measure was long-term effects (10 years) of BPD versus those associated with conventional therapy on microvascular outcome, micro- and macroalbuminuria, and glomerular filtration rate (GFR). Secondary measures included macrovascular outcomes, type 2 diabetes remission, glycated hemoglobin, and hyperlipidemia. RESULTS Ten-year GFR variation was -45.7 ± 18.8% in the medical arm and 13.6 ± 24.5% in the surgical arm (P < 0.001). Ten-year hypercreatininemia prevalence was 39.3% in control subjects and 9% in BPD subjects (P = 0.001). After 10 years, all BPD subjects recovered from microalbuminuria, whereas microalbuminuria appeared or progressed to macroalbuminuria in control subjects. Three myocardial infarctions, determined by electrocardiogram, and one stroke occurred in control subjects. After the 10-year follow-up, coronary heart disease (CHD) probability was 0.22 ± 0.10 and 0.05 ± 0.04 in the medical and surgical groups, respectively (P < 0.001). Remission from type 2 diabetes was observed in all patients within 1 year of surgery. Surgical and medical subjects had lost 34.60 ± 10.25 and 0.38 ± 6.10% of initial weight at the 10-year follow-up (P < 0.001). CONCLUSIONS Renal and cardiovascular complications were dramatically reduced in the surgical arm, indicating long-term benefits of BPD on diabetic complications, at least in the case of morbid obesity with decompensated type 2 diabetes.

Abstract
The past decade, particularly the last 18 months, witnessed a vigorous increase in interest in vitamin D from both the lay and biomedical worlds. Much of the growing interest in vitamin D is powered by new data being extracted from the National Health and Nutrition Examination Survey (NHANES). The newest statistics demonstrate that more than 90% of the pigmented populace of the United States (Blacks, Hispanics, and Asians) now suffer from vitamin D insufficiency (25-hydroxyvitamin D <30 ng/ml), with nearly three fourths of the white population in this country also being vitamin D insufficient. This represents a near doubling of the prevalence of vitamin D insufficiency seen just 10 yr ago in the same population. This review attempts to provide some explanation for: 1) the rapid decline in vitamin D status in the United States; 2) the adverse impact of vitamin D insufficiency on skeletal, infectious/inflammatory, and metabolic health in humans; and 3) the therapeutic rationale and reliable means for vigorous supplementation of our diets with vitamin D.

Abstract
BACKGROUND Vitamin D (VitD) deficiency is common following biliopancreatic diversion (BPD). We conducted a prospective open-label study to evaluate the efficacy of a single intramuscular injection with 600,000 IU of cholecalciferol in an arachis oil depot formulation (VitD3, Arachitol Solvay Pharmacia) as an adjunct to regular oral VitD supplementation (Citrical+D) for a period of 12 months following BPD surgery. METHODS Some 29 patients who had undergone BPD during 2000-2005 were recruited and received a single injection of 600,000 IU of cholecalciferol. Venous blood VitD, parathyroid hormone (PTH), alkaline phosphatase (ALP), ionised calcium and urinary N-telopeptide (NTX) were assessed at baseline and at 1.5, 3, 6, 9 and 12 months post-injection. Bone mineral density (BMD) was determined at baseline and 12 months post-injection. RESULTS VitD concentrations (mean +/- SD) were significantly increased from baseline values (61.5 +/- 18.8 nmol/L) at 1.5 months (92.4 +/- 21.5, p < 0.001), 3 months (100.5 +/- 24.4, p < 0.001) and 6 months (79.1 +/- 20.9, p = 0.014) post-injection, with non-significant elevations at 9 months (73.3 +/- 15.1, p = 0.248) and 12 months (73.4 +/- 17.3, p = 0.278). The proportion of patients with 'normalised' VitD levels was significantly higher at all post-injection time points (range, 93-100%) compared with baseline (71.4%; p < 0.01). Ionised calcium and ALP remained within normal levels at baseline and all follow-up time points, although ionised calcium decreased by 3.4% (p = 0.015) and ALP increased by 14.6% (p = 0.021) at 12 months compared with baseline. No significant change in PTH, NTX or BMD was observed. CONCLUSIONS Intramuscular cholecalciferol injection, as an adjunct to oral supplementation, appears a safe and effective method to increase and maintain VitD levels after BPD.

Abstract
The presence of nutritional deficiencies in overweight and obesity may seem paradoxical in light of excess caloric intake, but several micronutrient deficiencies appear to be higher in prevalence in overweight and obese adults and children. Causes are multifactorial and include decreased consumption of fruits and vegetables, increased intake of high-calorie, but nutritionally poor-quality foods, and increased adiposity, which may influence the storage and availability of some nutrients. As the obesity epidemic continues unabated and the popularity of bariatric surgery rises for severely obese adults and adolescents, medical practitioners must be aware of pre-existing nutritional deficiencies in overweight and obese patients and appropriately recognize and treat common and rare nutritional deficiencies that may arise or worsen following bariatric surgery. This article reviews current knowledge of nutritional deficits in obese and overweight individuals and those that commonly present after bariatric surgery and summarizes current recommendations for screening and supplementation.
