[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.

Obes Surg 2023; 33:3437-3446.

Abstract
INTRODUCTION Bariatric surgery predisposes patients to nutritional deficiencies. There are limited studies on zinc and copper abnormalities in this cohort. PURPOSE The aim of this study was to identify the prevalence of these abnormalities in a cohort of Australian bariatric patients. Inflammatory markers, adherence to multivitamin supplementation (MVS) and the presence of gastrointestinal (GI) symptoms were also investigated. MATERIAL AND METHODS Data was collected on all patients who attended a single clinic in Sydney, Australia, from August 2020 to August 2021. RESULTS The study cohort consisted of 231 patients (76.2% female; mean pre-operative body mass index of 43.4 ± 7.1 kg/m2), most of whom underwent sleeve gastrectomy (78.8%). Data were collected preoperatively and then at ≤ 6 months, 1 and > 2 years postoperatively. Prior to surgery, low levels of zinc (2.1%) and copper (0.7%) were rare, but elevated copper levels were common (16.7%) and potentially related to an elevated C-reactive protein (CRP) (47.7%). Following surgery at > 2 years, the mean total weight loss (TWL) was 33.5 ± 12.4. CRP levels improved over time. Post operatively, low zinc (2.7-3.6%) and copper (1.5%) levels were rare. Patients with low levels in zinc and copper were a higher-risk group and generally exhibited GI symptoms, despite taking MVS. CONCLUSION In the initial post-operative stages and with good adherence to MVS containing copper and zinc, abnormalities may not be a concern. Patients with GI symptoms appear to be at higher risk of abnormalities; increasing awareness, thorough screening, and more comprehensive supplementation are recommended.

BMC Geriatr 2021; 21:631. [PMID: 34736423 PMCID: PMC8567629 DOI: 10.1186/s12877-021-02578-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Accepted: 10/22/2021] [Indexed: 11/10/2022] Open
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
BACKGROUND The prevalence of obesity is considered to be increased worldwide. Lack of mineral elements is one of the essential side effects of bariatric surgery as a trending treatment for obesity. We aimed to assess zinc deficiency among morbidly obese patients before and following different types of bariatric surgical procedures. METHODS In the present retrospective cohort study, 413 morbidly obese patients (body mass index (BMI) ≥ 40 kg/m2 or BMI ≥ 35 kg/m2 with a complication or risk factor, e.g., diabetes mellitus) were enrolled who received bariatric surgery, aged between 18 and 65 years old, and had a negative history of active consumption of alcohol and illicit drugs. Patients were assigned into three groups of bariatric surgeries: mini-gastric bypass, Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG). We recorded baseline clinical and demographic characteristics and zinc serum levels during the preoperative and postoperative follow-up periods at three, six, and 12 months after the operation. RESULTS All patients with a mean age of 40.57 ± 10.63 years and a mean preoperative BMI of 45.78 ± 6.02 kg/m2 underwent bariatric surgery. 10.2% of the bariatric patients experienced zinc deficiency before the surgery, and 27.1% at 1 year after the surgery. The results showed that 27.7% of mini-gastric bypass patients, 29.8% of RYGB, and 13.3% of SG experienced zinc deficiency 12 months following surgery. We observed no statistical differences in the preoperative and postoperative zinc deficiency between different types of surgeries. CONCLUSION A high prevalence of preoperative zinc deficiency among morbidly obese patients who underwent bariatric surgery was observed, which increased during the postoperative periods. We recommend assessing zinc serum levels and prescribing zinc supplements before the bariatric operation to alleviate the prevalence of zinc deficiency after the operation.

Abstract
We performed a meta-analysis to provide quantitative estimates of fat mass (FM) and fat-free mass (FFM) changes in patients following bariatric surgery over 1 year. A systematic search of PubMed, SCOPUS and Web of Science databases was conducted; the pooled weighted mean difference (WMD) and 95% confidence intervals (CI) were calculated using a random-effects model. Thirty-four studies including Roux en-Y gastric bypass (RYGB), sleeve gastrectomy (SG) biliopancreatic diversion (BPD) and gastric banding (GB) were analyzed. RYGB decreased in body FM (-28.99 kg [31.21, -26.77]) or FM% (-12.73% [-15.14, -10.32]) or FFM (-9.97 kg [-10.93, -9.03]), which were greater than SG and GB. Moreover, the FFM% in RYGB group (11.72% [7.33, 16.11]) was more than SG (5.7% [4.44, 6.95]) and GB (8.1% [6.15, 10.05]) groups. Bariatric surgeries, especially RYGB, might be effective for a decrease in FM and maintenance of FFM in patients with morbid obesity in over 1 year.

Abstract
PURPOSE Bariatric surgery is the method of choice for the management or treatment of obesity. Bariatric surgery brings about several physiological changes in the body and is associated with set of complications. The aim of this study is to provide guidelines on post bariatric surgery management based on consensus by the Spanish society for Obesity Surgery (Sociedad Española de Cirugía de la Obesidad) (SECO) and the Spanish Society for the Study of Obesity (Sociedad Española para el Estudio de la Obesidad) (SEEDO). METHOD The boards proposed seven experts from each society. The experts provided the evidence and a grade of recommendation on the selected topics based on systematic reviews/meta-analysis. A list of clinical practical recommendations levels of evidence and grades of these recommendations was derived from the consensus statements from the members of these societies. RESULTS Seventeen topics related to post-operative management were reviewed after bariatric surgery. The experts came with 47 recommendations and statements. The mean number of persons voting at each statement was 54 (range 36-76). CONCLUSION In this consensus, we have designed a set of guidelines to be followed while managing patients after bariatric surgery. Expertise and knowledge of the clinicians are required to convey suitable considerations to the post-bariatric patients. There should also be extensive follow-up plans for the bariatric surgery patients.

Abstract
Exposure to the environmental toxicant cadmium (Cd) contributes to the development of obesity-associated diseases. Obesity is a risk factor for a spectrum of unhealthy conditions including systemic metabolic dyshomeostasis. In the present study, the effects of whole-life exposure to environmentally-relevant concentrations of Cd on systemic essential metal distribution in adult mice fed a high-fat diet (HFD) were examined. For these studies, male and female mice were exposed to Cd-containing drinking water for >2 weeks before breeding. Pregnant mice and dams with offspring were exposed to Cd-containing drinking water. After weaning, offspring were continuously exposed to the same Cd concentration as their parents, and divided into HFD and normal (low) fat diet (LFD) groups. At 10 and 24 weeks, mice were sacrificed and blood, liver, kidney and heart harvested for metal analyses. There were significant concentration dependent increases in Cd levels in offspring with kidney > liver > heart. Sex significantly affected Cd levels in kidney and liver, with female animals accumulating more metal than males. Mice fed the HFD showed > 2-fold increase in Cd levels in the three organs compared to similarly treated LFD mice. Cadmium significantly affected essential metals levels in blood, kidney and liver. Additionally, HFD affected essential metal levels in these three organs. These findings suggest that Cd interacts with HFD to affect essential metal homeostasis, a phenomenon that may contribute to the underlying mechanism responsible for the development of obesity-associated pathologies.

Abstract
BACKGROUND Micronutrient deficiencies are major concerns after bariatric surgery, although these conditions often go undiagnosed pre-surgery. OBJECTIVE To assess pre-surgery micronutrient status of an Iranian population of morbidly obese candidates of bariatric surgery in a cross-sectional study. METHODS A cross-sectional analysis of 2008 candidates for bariatric surgery, aged 15-65 years, with either body mass index (BMI) ≥ 40 kg/m2 or 30 < BMI < 35 kg/m2 with a medical comorbidity was conducted. In order to determine the micronutrient status of participants, blood samples were collected to assess serum concentrations of vitamins (B12 and D), minerals (copper, calcium, phosphate, and zinc), and iron profiles (total iron binding capacity, iron concentration, ferritin, and iron saturation), according to standard protocol. RESULTS The mean age and BMI of patients (79.3% female) were 37.8 years and 44.8 kg/m2, respectively. Deficiencies were found for 25(OH) D (53.6%), vitamin B12 (34.4%), serum iron (10.2%), and low levels of hemoglobin (16.6%). The prevalence of other deficiencies were all below 10%. Body mass index had a negative correlation with iron, calcium, vitamin B12, and 25(OH) D and was positively correlated with copper. CONCLUSION Micronutrient deficiencies, including vitamin D, vitamin B12, and iron, are commonly found among morbidly obese subjects who are potential candidates of bariatric surgery.

Abstract
The important prevalence and morbidity of obesity has generated an increase in bariatric surgery. It has a positive effect in obesity-related comorbidities. However, it's detrimental to bone health. The underline pathophysiological mechanisms are complex and heterogeneous. The knowledge of these factors may lead us to develop an adequate therapeutic intervention.

Abstract
A large number of patients undergoing bariatric surgery are deficient in copper, and Roux-en-Y gastric bypass can further aggravate it. Delays in diagnosis and treatment of copper deficiency can leave patients with residual neurological disability. This has led to recommendation from the British Obesity and Metabolic Surgery Society that copper levels should be monitored annually after gastric bypass. This review concludes that copper deficiency in adequately supplemented patients is rare and can be adequately treated if a related haematological or neurological disorder is diagnosed. The cost of routine monitoring may therefore not be justified for adequately supplemented, asymptomatic patients who have undergone Roux-en-Y gastric bypass. The screening may however be necessary for high-risk patient groups to prevent severe complications and permanent disability.

Boullata J, Muthukumaran G, Piarulli A, Labarre J, Compher C. Oral copper absorption in men with morbid obesity. J Trace Elem Med Biol 2017; 44:146-150. [PMID: 28965570 DOI: 10.1016/j.jtemb.2017.07.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2017] [Revised: 07/11/2017] [Accepted: 07/21/2017] [Indexed: 12/23/2022]
Abstract
Copper deficiency has been reported in patients with severe obesity, both before and after bariatric surgery, the latter at increased rates. However, little is known about the absorption of copper. Because of differences in copper dynamics between men and women in the limited available data, we evaluated copper absorption in men who were candidates for bariatric surgery. All patients gave informed consent, approved by the University of Pennsylvania Institutional Review Board, to participate in a pharmacokinetics study. After a 12-h fast, body composition was measured using air displacement plethysmography and a single oral dose of 4mg copper gluconate was given followed by serial measures of serum copper over 10h. Meals and snacks very low in copper were provided. The seven participants had age 52±8years, BMI 44.87±9.01kg/m2 and fat free mass 77.92±14.45kg. Baseline serum copper was 36.1±19.5μg/dL and ceruloplasmin was 50.86±4.58mg/dL. Peak copper absorption occurred within 1-2h. The AUC for six subjects was 254.6±151.3μg/100mLh. The estimated volume of distribution (1.98±0.36L) was ∼25mL/kg fat free mass. In these severely obese men, copper absorption occurred early in spite of their normal copper status, suggesting no impairment of absorption due to obesity. Further studies of copper absorption after the significant weight loss and possible malabsorption derived from bariatric surgery are needed.

Abstract
AIM The aim of this observational study was to investigate the reported practices of Australian dietitians managing bariatric surgery patients in the preoperative stage. METHODS An online survey of dietitians providing nutritional care to bariatric patients was developed for the purpose of this investigation. The survey questions were guided by the Clinical Practice Guidelines for the Perioperative Nutritional, Metabolic and Nonsurgical Support of the Bariatric Surgery Patient guidelines and current literature. RESULTS Ninety-nine dietitians completed the survey. Most participants recommended one to two different medical nutrition therapy strategies for preoperative weight loss (n = 69, 74%), with a very-low-energy diet exclusively from liquid meal replacements being the most frequently prescribed (n = 62, 69%). A significantly higher proportion of dietitians working privately reported the involvement of a bariatric surgeon in the multidisciplinary team (P = 0.002). More private practitioners also reported providing education on the nutritional consequences of the different types of bariatric procedures (P = 0.005) and postoperative vitamin and mineral supplementation (P = 0.013), as well as the use of the guidelines to guide their practice (P = 0.014), compared to dietitians who worked in the public sector. A higher proportion of dietitians working in metropolitan areas reported that screening occurred more frequently for vitamin D (P = 0.008), fasting blood lipids (P = 0.03) and glycated haemoglobin (P = 0.003) compared to those in regional/rural/remote areas. CONCLUSIONS Reported preoperative screening practices were not consistent with the recommendations from the literature and current American guidelines. Further investigation into the difference in the nutritional management strategies and work environments is warranted.

Abstract
OBJECTIVES The objectives of this study were to investigate the occurrence of oxidative stress, status of protective antioxidants enzymes, inflammatory biomarkers, and some metabolic health variables in the blood and to compare the results between those of the normal controls and obese patients submitted to sleeve gastrectomy-induced weight loss over a 1-year follow-up period. MATERIALS AND METHODS A prospective study was conducted in Aseer Central Hospital and Abha Private Hospital in the Kingdom of Saudi Arabia from January 2012 to January 2013 on 50 normal (BMI = 22-25 kg/m2) control subjects and 50 obese (BMI = 45-50 kg/m2) patients. A subset of 20 men and 80 women patients, aged 20-45 years, was included. The systemic blood cell counts were determined by Beckman Coulter UniCel analyzer. The occurrence of oxidative stress, the status of antioxidant enzyme system in the blood, levels of serum hepatic enzymes, cardiovascular risk factors, and serum sodium, potassium, copper, and zinc levels were determined by spectrophotometric procedures. The concentration of TSH and T4 were analyzed by Siemens Immunoassay System. RESULTS Group 1 (Obese: preoperative) This group compared with the normal controls exhibited significant (p < 0.05) increase in inflammatory biomarkers, a significant (p < 0.05) rise in hepatic enzymes, a significant (p < 0.05) decrease in serum total bilirubin. Concentration of serum total cholesterol (TC), triacylglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and fasting blood glucose(FBG) were significantly (p < 0.05) increased, but HDL cholesterol (HDL-C) was significantly depleted (p < 0.05). Serum urea and creatinine contents were significantly (p < 0.05) decreased. Serum copper and zinc levels were significantly (p < 0.05) increased. Group 2: Sleeve Gastrectomy Surgery (Obese: postoperative) This group compared with the obese group, preoperatively, demonstrated a profound reduction in body weight (-32%) as well as in BMI (-29%). Serum malondialdehyde, a stress index, was significantly (p < 0.001) inhibited and conversely, activities of antioxidant enzymes: superoxide dismutase(Cu-Zn SOD), glutathione peroxidase (GPx), glutathione-S-transferase (GST), glucose-6-phosphate dehydrogenase (G6PDH), and vitamin C, were remarkably (p < 0.001) increased. Furthermore, remarkable improvements in deranged metabolic variables approaching normality were discernible. Inflammatory biomarkers in the blood and hepatic enzymes in serum were significantly (p < 0.001) decreased. Levels of TC, TG, LDL-C, FBG, and HDL-C in serum exhibited significant (p < 0.05) reductions, a reversal toward normality. Serum albumin and total bilirubin concentrations were significantly increased (p < 0.001). Serum sodium, potassium, copper, zinc, and TSH levels were significantly (p < 0.001) decreased. CONCLUSIONS Obesity is a chronic disease of multifactorial origin and resulted in perturbations of whole body metabolism in this study. It is thus likely that this imbalance was associated with an inhibition in protective antioxidants and occurrence of oxidative stress. The staging concept of sleeve gastrectomy is a safe and effective approach with remarkable efficacy in sustaining weight loss and bringing back normal metabolism of variables in tissues over a 1-year follow-up period.

Abstract
Polycystic ovary syndrome (PCOS) is associated with infertility, increased androgen levels, and insulin resistance. In adipose tissue, zinc facilitates insulin signaling. Circulating zinc levels are altered in obesity, diabetes, and PCOS; and zinc supplementation can ameliorate metabolic disturbances in PCOS. In adipose tissue, expression of zinc influx transporter ZIP14 varies with body mass index (BMI), clinical markers of metabolic syndrome, and peroxisome proliferator-activated receptor gamma (PPARG). In this study, we investigated expression levels of ZIP14 and PPARG in subcutaneous adipose tissue of 36 PCOS women (17 lean and 19 obese women) compared with 23 healthy controls (7 lean and 16 obese women). Further, expression levels of zinc transporter ZIP9, a recently identified androgen receptor, and zinc efflux transporter ZNT1 were investigated, alongside lipid profile and markers of glucose metabolism [insulin degrading enzyme, retinol-binding protein 4 (RBP4), and glucose transporter 4 (GLUT4)]. We find that ZIP14 expression is reduced in obesity and positively correlates with PPARG expression, which is downregulated with increasing BMI. ZNT1 is upregulated in obesity, and both ZIP14 and ZNT1 expression significantly correlates with clinical markers of altered glucose metabolism. In addition, RBP4 and GLUT4 associate with obesity, but an association with PCOS as such was present only for PPARG and RBP4. ZIP14 and ZNT1 does not relate to clinical androgen status and ZIP9 is unaffected by all parameters investigated. In conclusion, our findings support the existence of a zinc dyshomeostasis in adipose tissue in metabolic disturbances including PCOS-related obesity.

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
Zinc is a signaling molecule in numerous metabolic pathways, the coordination of which occurs through activity of zinc transporters. The expression of zinc transporter Zip14 (Slc39a14), a zinc importer of the solute carrier 39 family, is stimulated under proinflammatory conditions. Adipose tissue upregulates Zip14 during lipopolysaccharide-induced endotoxemia. A null mutation of Zip14 (KO) revealed that phenotypic changes in adipose include increased cytokine production, increased plasma leptin, hypertrophied adipocytes, and dampened insulin signaling. Adipose tissue from KO mice had increased levels of preadipocyte markers, lower expression of the differentiation marker (PPARγ), and activation of NF-κB and STAT3 pathways. Our overall hypothesis was that ZIP14 would play a role in adipocyte differentiation and inflammatory obesity. Global Zip14 KO causes systemic endotoxemia. The observed metabolic changes in adipose metabolism were reversed when oral antibiotics were administrated, indicating that circulating levels of endotoxin were in part responsible for the adipose phenotype. To evaluate a mechanism, 3T3-L1 cells were differentiated into adipocytes and treated with siRNA to knock down Zip14. These cells had an impaired ability to mobilize zinc, which caused dysregulation of inflammatory pathways (JAK2/STAT3 and NF-κB). The Zip14 deletion may limit the availability of intracellular zinc, yielding the unique phenotype of inflammation coupled with hypertrophy. Taken together, these results suggest that aberrant zinc distribution observed with Zip14 ablation impacts adipose cytokine production and metabolism, ultimately increasing fat deposition when exposed to endotoxin. To our knowledge, this is the first investigation into the mechanistic role of ZIP14 in adipose tissue regulation and metabolism.

Abstract
Metabolic syndrome is associated with several disorders, including hypertension, diabetes, hyperlipidemia as well as cardiovascular diseases and stroke. Plant-derived polyphenols, compounds found in numerous plant species, play an important role as potential treatments for components of metabolic syndrome. Studies have provided evidence for protective effects of various polyphenol-rich foods against metabolic syndrome. Fruits, vegetables, cereals, nuts, and berries are rich in polyphenolic compounds. Grapes (Vitis vinifera), especially grape seeds, stand out as rich sources of polyphenol potent antioxidants and have been reported helpful for inhibiting the risk factors involved in the metabolic syndrome such as hyperlipidemia, hyperglycemia, and hypertension. There are also many studies about gastroprotective, hepatoprotective, and anti-obesity effects of grape polyphenolic compounds especially proanthocyanidins in the literature. The present study investigates the protective effects of grape seeds in metabolic syndrome. The results of this study show that grape polyphenols have significant effects on the level of blood glucose, lipid profile, blood pressure, as well as beneficial activities in liver and heart with various mechanisms. In addition, the pharmacokinetics of grape polyphenols is discussed. More detailed mechanistic investigations and phytochemical studies for finding the exact bioactive component(s) and molecular signaling pathways are suggested.

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

Abstract
BACKGROUND Obesity surgery is acknowledged as a highly effective therapy for morbidly obese patients. Beneficial short-term effects on common comorbidities are practically undisputed, but a growing data pool from long-term follow-up reveals increasing evidence of potentially severe nutritional and pharmacological consequences. AIMS To assess the prevalence, causes and symptoms of complications after obesity surgery, to elucidate and compare therapy recommendations for macro- and micronutrient deficiencies, and to explore surgically-induced effects on drug absorption and bioavailability, discussing ramifications for long-term therapy and prophylaxis. METHODS PubMed, Embase and MEDLINE were searched using terms including, but not limited to, bariatric surgery, gastric bypass, obesity surgery and Roux-en-Y, coupled with secondary search terms, e.g. anaemia, micronutrients, vitamin deficiency, bacterial overgrowth, drug absorption, pharmacokinetics, undernutrition. All studies in English, French or German published January 1980 through March 2014 were included. RESULTS Macro- and micronutrient deficiencies are common after obesity surgery. The most critical, depending on surgical technique, are hypoalbuminemia (3-18%) and deficiencies of vitamins B1 (≤49%), B12 (19-35%) and D (25-73%), iron (17-45%) and zinc (12-91%). Many drugs commonly administered to obese patients (e.g. anti-depressants, anti-microbials, metformin) are subject to post-operative and/or PPI-associated changes affecting bioavailability and absorption. CONCLUSIONS Complications are associated with pre-operative and/or post-operative malnutrition or procedure-related changes in intake, absorption and drug bioavailability. The high prevalence of nutrient deficiencies after obesity surgery makes life-long nutritional monitoring and supplementation essential. Post-operative changes to drug absorption and bioavailability in bariatric patients cast doubt on the validity of standard drug dosage and administration recommendations.

Abstract
We report a case of clinically significant micronutrient deficiencies following biliary pancreatic diversion (BPD) surgery. Our patient was admitted to hospital six years after BPD surgery following a low impact humeral fracture complicated by postoperative wound infection. On presentation she complained of a widespread rash and loss of night vision. Laboratory testing confirmed hypoalbuminaemia, deficiencies of vitamins A, E and D and of the trace elements copper, zinc and selenium. Bone densitometry confirmed osteoporosis. The skin rash was thought to be due to zinc deficiency and improved with conservative measures and trace element replacement. Her night blindness resolved 48 hours after receiving high dose parenteral vitamin A. Six months later she was readmitted to our intensive care unit with wound dehiscence at her fracture site and clinical features of sepsis and encephalopathy. This case highlights the importance of devising treatment and follow-up guidance prior to surgery and multidisciplinary team involvement including the patient so that long-term metabolic complications are avoided.

Abstract
Objective. The correlation between obesity and deficient wound healing has long been established. This review examines the current literature on the mechanisms involved in obesity-related perioperative morbidity. Methods. A literature search was performed using Medline, PubMed, Cochrane Library, and Internet searches. Keywords used include obesity, wound healing, adipose healing, and bariatric and surgical complications. Results. Substantial evidence exists demonstrating that obesity is associated with a number of postoperative complications. Specifically in relation to wound healing, explanations include inherent anatomic features of adipose tissue, vascular insufficiencies, cellular and composition modifications, oxidative stress, alterations in immune mediators, and nutritional deficiencies. Most recently, advances made in the field of gene array have allowed researchers to determine a few plausible alterations and deficiencies in obese individuals that contribute to their increased risk of morbidity and mortality, especially wound complications. Conclusion. While the literature discusses how obesity may negatively affect health on various of medical fronts, there is yet to be a comprehensive study detailing all the mechanisms involved in obesity-related morbidities in their entirety. Improved knowledge and understanding of obesity-induced physiological, cellular, molecular, and chemical changes will facilitate better assessments of surgical risks and outcomes and create efficient treatment protocols for improved patient care of the obese patient population.

Abstract
Bariatric surgery, and in particular, gastric bypass, is an increasingly utilized and successful approach for long-term treatment of obesity and amelioration of comorbidities. Nutrient deficiencies after surgery are common and have multiple causes. Preoperative factors include obesity, which appears to be associated with risk for several nutrient deficiencies, and preoperative weight loss. Postoperatively, reduced food intake, suboptimal dietary quality, altered digestion and absorption, and nonadherence with supplementation regimens contribute to risk of deficiency. The most common clinically relevant micronutrient deficiencies after gastric bypass include thiamine, vitamin B₁₂, vitamin D, iron, and copper. Reports of deficiencies of many other nutrients, some with severe clinical manifestations, are relatively sporadic. Diet and multivitamin use are unlikely to consistently prevent deficiency, thus supplementation with additional specific nutrients is often needed. Though optimal supplement regimens are not yet defined, most micronutrient deficiencies after gastric bypass currently can be prevented or treated by appropriate supplementation.

Obesity (Silver Spring) 2013; 21 Suppl 1:S1-27. [PMID: 23529939 PMCID: PMC4142593 DOI: 10.1002/oby.20461] [Citation(s) in RCA: 734] [Impact Index Per Article: 66.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2012] [Accepted: 12/27/2012] [Indexed: 02/06/2023]
Abstract
The development of these updated guidelines was commissioned by the AACE, TOS, and ASMBS Board of Directors and adheres to the AACE 2010 protocol for standardized production of clinical practice guidelines (CPG). Each recommendation was re-evaluated and updated based on the evidence and subjective factors per protocol. Examples of expanded topics in this update include: the roles of sleeve gastrectomy, bariatric surgery in patients with type-2 diabetes, bariatric surgery for patients with mild obesity, copper deficiency, informed consent, and behavioral issues. There are 74 recommendations (of which 56 are revised and 2 are new) in this 2013 update, compared with 164 original recommendations in 2008. There are 403 citations, of which 33 (8.2%) are EL 1, 131 (32.5%) are EL 2, 170 (42.2%) are EL 3, and 69 (17.1%) are EL 4. There is a relatively high proportion (40.4%) of strong (EL 1 and 2) studies, compared with only 16.5% in the 2008 AACE-TOS-ASMBS CPG. These updated guidelines reflect recent additions to the evidence base. Bariatric surgery remains a safe and effective intervention for select patients with obesity. A team approach to perioperative care is mandatory with special attention to nutritional and metabolic issues.

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.
