An Update on Vitamin D Deficiency Status in Malaysia. Nutrients 2022; 14:nu14030567. [PMID: 35276926 PMCID: PMC8838715 DOI: 10.3390/nu14030567] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 12/24/2021] [Accepted: 12/28/2021] [Indexed: 02/04/2023] Open
Abstract
Vitamin D is essential for maintaining serum calcium levels, ensuring sufficient bone mineralization, immunomodulatory properties, and a protective effect on the cardiovascular system, renal disease, cancer, as well as in pregnancy. Vitamin D deficiency is prevalent worldwide, and it is not related to a country's development index. However, the data on vitamin D deficiencies are primarily taken from out-of-date, small-scale studies on target age groups or specific diseases, rather than from large-scale, population-based surveys. In Malaysia, for the past 16 years, studies were conducted involving adult men and women, pregnant women, postmenopausal women, adolescent, and children especially with specific diseases such as spina bifida, epilepsy, chronic liver disease, and atopic dermatitis. Only a few large surveys were conducted involving children and adolescents. Across the specific target population studied, vitamin D deficiency and insufficiency were seen particularly among females, Indians, and those of Malay ethnicity. This is related to widely known causes of vitamin D deficiency such as skin type (melanin) and sun avoidant lifestyles that include covering clothes, largely practiced by Malay Muslims in Malaysia. Other related causes or the high-risk groups are breastfed infants, the elderly, the obese, those on medications, and those characterized by fat malabsorption and geophysical factors. Vitamin D deficiency can be managed with pharmacological or non-pharmacological approaches, depending on the severity. The objective is to raise serum vitamin D to a normal level, hence, relieving the symptoms and reducing the adverse health outcomes. Despite no clear guidelines in treating vitamin D deficiency in Malaysia, this condition can be prevented with taking adequate vitamin D in food resources, sun exposure, or supplementation. Special attention should be given to high-risk groups including infants, obese patients, and the elderly.

Abstract
We report a case of a 29-year-old woman admitted twice to our hospital with diabetic ketoacidosis (DKA) within 45 days following her bariatric surgery. The first admission required intensive care during her postoperative days after bariatric surgery. Subsequently, she continued to report high level of ketones on a daily basis. At her second admission, she presented with all three criteria of DKA. She was treated with a standard protocol for DKA, but ketones plasma level remained high despite significant improvement in pH and glycemic control. The administration of thiamine replacement was associated with normalization of the hyperketonemia. Thiamine deficiency can be associated with bariatric surgery and can lead to high ketone level in individuals with type 1 diabetes.

Greater Adherence to Cancer Prevention Guidelines Is Associated with Higher Circulating Concentrations of Vitamin D Metabolites in a Cross-Sectional Analysis of Pooled Participants from 2 Chemoprevention Trials. J Nutr 2017; 147:421-429. [PMID: 28122932 DOI: 10.3945/jn.116.243352] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2016] [Revised: 11/28/2016] [Accepted: 01/04/2017] [Indexed: 12/14/2022] Open
Abstract
Background: Several lifestyle factors targeted by the American Cancer Society (ACS) Nutrition and Physical Activity Cancer Prevention Guidelines are also associated with circulating concentrations of vitamin D metabolites. This suggests that greater adherence to the ACS guidelines may be related to better vitamin D status.Objective: We examined the relation between adherence to the ACS guidelines and circulating concentrations of 2 vitamin D metabolites, 25-hydroxycholecalciferol [25(OH)D] and 1α,25-dihydroxyvitamin D [1,25(OH)2D].Methods: We conducted cross-sectional analyses of pooled participants from the Wheat Bran Fiber (n = 503) and Ursodeoxycholic Acid (n = 854) trials. A cumulative adherence score was constructed with the use of baseline data on body size, diet, physical activity, and alcohol consumption. Continuous vitamin D metabolite concentrations and clinically relevant categories were evaluated with the use of multiple linear and logistic regression models, respectively.Results: The most adherent participants were more likely to be older, white, and nonsmokers than were the least adherent. A statistically significant association was observed between guideline adherence and concentrations of circulating 25(OH)D (means ± SEs-high adherence: 32.0 ± 0.8 ng/mL; low adherence: 26.4 ± 0.7 ng/mL; P-trend < 0.001). For 1,25(OH)2D concentrations, high adherence was again significantly related to greater metabolite concentrations, with mean ± SE concentrations of 36.3 ± 1.3 pg/mL and 31.9 ± 1.0 pg/mL for high- and low-adherers, respectively (P-trend = 0.008). Furthermore, the odds of attaining a sufficient 25(OH)D status were 4.37 times higher for those most adherent than for those least adherent (95% CI: 2.47, 7.71 times).Conclusion: These findings demonstrate that greater adherence to the ACS guidelines is associated with higher circulating concentrations of both of 25(OH)D and 1,25(OH)2D.

Abstract
To assess if altered bone turnover following bariatric surgery is related to metabolic consequences of the surgical procedure or weight loss. We evaluated serum markers reflecting bone turnover and metabolic pathways at baseline and after 1-year in a controlled non-randomized clinical trial comparing Roux-en-Y gastric bypass surgery (n = 74) with lifestyle intervention (n = 63) on obesity-related comorbidities. The decrease in body mass index (BMI) was larger in the surgery (-14.0 kg/m(2)) compared to lifestyle (-3.7 kg/m(2)). Markedly increased bone turnover was observed following surgery compared to lifestyle intervention and was correlated with change in BMI. Stepwise multivariable regression analysis revealed that group (β = 0.31, p < 0.01), and changes in BMI (β = -0.28, p < 0.01), dickkopf-1 (β = 0.20, p < 0.001) and sclerostin (β = 0.11, p < 0.05) were predictors of change in the bone resorption marker N-terminal telopeptide. Our data support that mechanisms related to the procedure itself and changes in secreted Wnt antagonists may contribute to increased bone turnover following bariatric surgery.

Loose and frequent stools and PTH levels are positively correlated post-gastric bypass surgery due to less efficient intestinal calcium absorption. Surg Obes Relat Dis 2016; 12:1548-1553. [PMID: 27396549 DOI: 10.1016/j.soard.2016.04.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Revised: 03/07/2016] [Accepted: 04/10/2016] [Indexed: 01/17/2023]
Abstract
BACKGROUND After Roux-en-Y gastric bypass, calcium and vitamin D deficiencies are frequently reported. In the presence of adequate vitamin D levels, calcium deficiency is caused by a lower efficacy of the intestinal calcium transport. OBJECTIVE To investigate whether the use of a simple clinical score quantifying bowel habits (fecal score [FS]) correlates with the degree of secondary hyperparathyroidism that arises to compensate for calcium deficiency postsurgery. SETTING Large peripheral hospital. METHODS Seventy-five patients supplemented with calcium and vitamin D were prospectively studied before and 6 and 12 months after Roux-en-Y gastric bypass. FS, calcium (mmol/L), phosphate (mmol/L), magnesium (mmol/L), vitamin D (nmol/L), and parathyroid hormone (PTH; pmol/L) were measured in each patient. RESULTS Mean body mass index was 44.7±5.4 kg/m2 preoperatively and decreased to 34.3±5.0 kg/m2 at 6 months and 30.8±4.8 kg/m2 at 12 months, corresponding to a total weight loss of 23.2±5.9% and 30.9±8.3% respectively. There were no significant changes in serum calcium levels. Mean PTH levels rose from 3.5 pmol/L at baseline to 4.1 pmol/L at 6 months (P = .01) and to 4.9 pmol/L at 12 months (P<.001). Nine patients (12%) had increased PTH levels at 6 months, and 14 patients (19%) had increased PTH levels at 12 months. A significant positive correlation between FS and PTH at 12 months was found, which persisted after adjusting for vitamin D levels. CONCLUSION FS is positively correlated with secondary hyperparathyroidism using vitamin D-adjusted PTH levels as a biochemical marker. The present study in humans confirms the relation reported in animal studies. These results emphasize that managing stool habits are important after bariatric surgery.

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

Abstract
BACKGROUND Nutritional deficiencies are common among morbidly obese patients. Data are scarce for patients who have undergone laparoscopic sleeve gastrectomy (LSG). OBJECTIVES The aim of the study is to clarify the prevalence of deficiencies and to identify risk factors for postoperative deficiencies. SETTINGS Hebrew University, Israel. METHODS Preoperative and 1-year postoperative data were collected. We included anthropometric parameters, obesity-related co-morbidities, and laboratory findings. RESULTS There were 192 candidates. Seventy-seven of them completed follow-ups at 12 months. Before surgery, 15% had anemia. Deficiencies of iron, folate, and B12 were 47%, 32%, and 13%, respectively. Women were more deficient in iron (56% women, 26% men, P<.001). Before surgery, low levels of vitamin D and elevated parathyroid hormone (PTH) were 99% and 41%, respectively. One year postsurgery, the deficiencies of hemoglobin and vitamin B12 worsened (20% and 17%, P<.001, P = .048, respectively). One year postsurgery, deficiencies of iron, folate, vitamin D, and PTH improved (28%, 21%, 94%, and 10%, respectively). Deficiencies of hemoglobin, folate, and B12 before surgery were predictors for deficiencies 1 year after surgery (P = .006 OR = .090; P = .012 OR = .069; P = .062 OR = .165, respectively). CONCLUSIONS LSG had a modest effect on nutritional deficiencies in our patients at 1-year postsurgery. Focusing on the preoperative nutritional status and tailoring a specific supplemental program for each individual should prevent postoperative deficiencies.

Abstract
Obesity is commonplace, and surgical treatment usually includes Roux-en-Y gastric bypasses (RYGBs). RYGBs have the most documented side effects including vitamin deficiencies, rebound weight gain, and symptomatic hypoglycemia; fewer series exist describing hypoglycemia following other bariatric operations. We reviewed all patients undergoing laparoscopic adjustable gastric banding (LAGB) at our institution between 2008 and 2012. Three patients were identified to have symptomatic hypoglycemia following LAGB. Mean time from surgery was 33 months (range 14–45 months), and mean weight loss was 32.7 kg (range 15.9–43.1 kg). None of the patients had preexisting diabetes. Therefore, symptomatic hypoglycemia should be investigated irrespective of bariatric operation.

Abstract
Is bariatric surgery as primary therapy for type 2 diabetes mellitus (T2DM) with body mass index (BMI) <35 kg/m(2) justified? Open-label studies have shown that bariatric surgery causes remission of diabetes in some patients with BMI <35 kg/m(2). All such patients treated had substantial weight loss. Diabetes remission was less likely in patients with lower BMI than those with higher BMI, in patients with longer than shorter duration and in patients with lesser than greater insulin reserve. Relapse of diabetes increases with time after surgery and weight regain. Deficiencies of data are lack of randomized long-term studies comparing risk/benefit of bariatric surgery to contemporary intensive medical therapy. Current data do not justify bariatric surgery as primary therapy for T2DM with BMI <35 kg/m(2).

Abstract
It is estimated that the prevalence of anaemia in patients scheduled for bariatric surgery is higher than in the general population and the prevalence of iron deficiencies (with or without anaemia) may be higher as well. After surgery, iron deficiencies and anaemia may occur in a higher percentage of patients, mainly as a consequence of nutrient deficiencies. In addition, perioperative anaemia has been related with increased postoperative morbidity and mortality and poorer quality of life after bariatric surgery. The treatment of perioperative anaemia and nutrient deficiencies has been shown to improve patients’ outcomes and quality of life. All patients should undergo an appropriate nutritional evaluation, including selective micronutrient measurements (e.g., iron), before any bariatric surgical procedure. In comparison with purely restrictive procedures, more extensive perioperative nutritional evaluations are required for malabsorptive procedures due to their nutritional consequences. The aim of this study was to review the current knowledge of nutritional deficits in obese patients and those that commonly appear after bariatric surgery, specifically iron deficiencies and their consequences. As a result, some recommendations for screening and supplementation are presented.

Abstract
In recent years the number of bariatric surgery has markedly increased in industrial nations. Surgery provides a more rapid decrease of body weight than conservative approach. However a long term conservative follow up therapy is mandatory to stabilize reduced weight. Due to increasing knowledge from long term follow up of surgically treated obese patients there is a growing body of evidence that frequently there is necessity of reoperations and of substitution both of trace elementsand of minerals or vitamins due to their hampered enteral resorption. Additionally therapy of surgery induced endocrine alterations not seldom is necessary.These insights are of outstanding importance because meanwhile an enlargement of the indications for bariatric surgery as a therapeutic option for metabolic disorders is being discussed. This review refers to the recent internationally published papers concerning consequences of bariatric surgery.

Abstract
Vitamin D insufficiency affects almost 50% of the population worldwide. An estimated 1 billion people worldwide, across all ethnicities and age groups, have a vitamin D deficiency (VDD). This pandemic of hypovitaminosis D can mainly be attributed to lifestyle (for example, reduced outdoor activities) and environmental (for example, air pollution) factors that reduce exposure to sunlight, which is required for ultraviolet-B (UVB)-induced vitamin D production in the skin. High prevalence of vitamin D insufficiency is a particularly important public health issue because hypovitaminosis D is an independent risk factor for total mortality in the general population. Current studies suggest that we may need more vitamin D than presently recommended to prevent chronic disease. As the number of people with VDD continues to increase, the importance of this hormone in overall health and the prevention of chronic diseases are at the forefront of research. VDD is very common in all age groups. As few foods contain vitamin D, guidelines recommended supplementation at suggested daily intake and tolerable upper limit levels. It is also suggested to measure the serum 25-hydroxyvitamin D level as the initial diagnostic test in patients at risk for deficiency. Treatment with either vitamin D2 or vitamin D3 is recommended for deficient patients. A meta-analysis published in 2007 showed that vitamin D supplementation was associated with significantly reduced mortality. In this review, we will summarize the mechanisms that are presumed to underlie the relationship between vitamin D and understand its biology and clinical implications.

Abstract
PURPOSE OF REVIEW Bariatric surgery is an important option for the treatment of severe (type III) obesity. Its role in the management of type 2 diabetes in overweight and obese patients needs to be defined. RECENT FINDINGS Intensified medical therapy can achieve target metabolic goals in many but not all patients with type 2 diabetes. Bariatric surgery can normalize or improve glycemia in severely obese patients with type 2 diabetes. The complications of bariatric surgery are significant and include operative mortality, early and late surgical complications and late nutritional deficiencies. Comparative studies of bariatric surgery versus intensive medical therapy in the management and clinical outcomes of patients with type 2 diabetes are needed to evaluate relative risk/benefit of each. Bariatric surgery studies in type 2 diabetes are lacking long-term follow-up metabolic and clinical outcomes data. SUMMARY Current data are insufficient to recommend bariatric surgery as a primary treatment for type 2 diabetes. However, it can be recommended for patients whose target metabolic control cannot be achieved by intensive glycemic control because of intolerance or inadequate responses to nutritional and pharmacologic treatments.

Abstract
Vitamin D is essential for a vast number of physiologic processes, and thus adequate levels are necessary for optimal health. During childhood and adolescence, an adequate vitamin D status is needed due to its important role in cell growth, skeletal development and growth. Vitamin D is a fat-soluble vitamin that is naturally found in very few foods, is added to others, and is available as a dietary supplement. It is produced endogenously when ultraviolet light strikes the skin. The adequate intake and status of vitamin D greatly depends on age, concomitant diseases and the use of some medications that are covered in-depth in the article. Recent epidemiologic and experimental evidence has suggested that low vitamin D concentrations seem to be significantly associated with all-cause mortality, cardiovascular disease, cancer (mainly breast, prostate and colorectal), hypertension, metabolic syndrome, diabetes mellitus type 1 and type 2. However, the data supporting protective effects of vitamin D supplementation on conditions other than skeletal diseases like rickets, osteoporosis and osteomalacia are very weak, and the large, controlled clinical trials that are in progress now should resolve this issue.

Abstract
Surgical options for the treatment of adolescent obesity have been gaining popularity. Adolescent patients present a particular challenge to clinicians, secondary to age-related issues, revolving around both mental and physical growth. These age-related issues require a unique approach to nutritional intervention for adolescents undergoing bariatric surgery as opposed to standardized approaches for adults. Despite the increasing numbers of adolescents undergoing obesity surgery, evidence-based nutritional guidelines have yet to be published. The goal of this document is to provide the clinician with recommendations on how to assess, educate, nourish, and monitor the adolescent who has undergone obesity surgery. A multidisciplinary panel composed of 3 pediatric gastroenterologists, 1 psychologist, and 3 registered dietitians from the Nutrition Committee for the North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition and National Association of Children's Hospitals and Related Institutions, with experience in nutrition and adolescent weight loss surgery, reviewed the medical literature for evidence-based practice for nutritional strategies for patients undergoing bariatric surgery. In addition to this group, an adolescent medicine physician was consulted for matters related to reproductive health. The present article presents a consensus of recommendations based on a review of the literature. In areas for which there was a lack of evidence to support the recommendations, best-practice guidelines were used. The present article provides the clinician with an overview of the nutritional concerns for adolescent patients undergoing obesity surgery. These guidelines address the preoperative educational pathway, the postoperative diet progression, recognition of disordered eating, guidelines for female reproductive issues, and assistance for the adolescent in a school/college environment.

Abstract
Background Recently, the laparoscopic sleeve gastrectomy (LSG) has become popular as a single-stage procedure for the treatment of morbid obesity and its co-morbidities. However, the incidence of micronutrient deficiencies after LSG have hardly been researched. Methods From January 2005 to October 2008, 60 patients underwent LSG. All patients were instructed to take daily vitamin supplements. Patients were tested for micronutrient deficiencies 6 and 12 months after surgery. Results Anemia was diagnosed in 14 (26%) patients. Iron, folic acid, and vitamin B12 deficiency was found in 23 (43%), eight (15%), and five (9%) patients, respectively. Vitamin D and albumin deficiency was diagnosed in 21 (39%) and eight (15%) patients. Hypervitaminosis A, B1, and B6 were diagnosed in 26 (48%), 17 (31%), and 13 (30%) patients, respectively. Conclusions Due to inadequate intake and uptake of micronutrients, patients who underwent LSG are at serious risk for developing micronutrient deficiencies. Moreover, some vitamins seem to increase to chronic elevated levels with possible complications in the long-term. Multivitamins and calcium tablets should be regarded only as a minimum and supplements especially for iron, vitamin B12, vitamin D, and calcium should be added to this regimen based on regular blood testing.

Abstract
The biliopancreatic diversion is currently the maximum variant of bariatric surgery. It presents several opportunities of typical surgical complications, beside the risks generally prevailing in bariatric surgery. In addition, there is the procedure-immanent risk of development of nutritional deficiencies in the long-term process, at significant percentages. These deficiencies can, to a great extent, be avoided by consistent supplementation within the scope of a structured follow-up program; they can also be corrected by a substitution therapy. In the future, the risk of malnutrition can possibly be lowered by technically modified procedures with equal bariatric effectiveness. Considering the very good long-term results with regard to stable weight reduction in connection with a high recovery rate of the comorbidities, combined with a consistent postal-surgical management, the problem of malnutrition appears to be of minor importance. However, an appropriate compliance of the patient is also required.

Abstract
Patients with type 2 diabetes mellitus (T2DM) are usually treated with pharmacologic agents in combination with lifestyle modification. The development of new antidiabetic agents, such as insulin analogs and incretin-based therapies, has led to treatment strategies that enable many patients with T2DM to achieve target HbA(1c) levels (≤7.0%). However, many factors-including those related to the patient or the health-care provider, drug inadequacies and adverse effects-can interfere with the ability of some patients to reach metabolic targets. Clinical data from the USA indicate that HbA(1c) concentration, blood pressure and serum levels of lipids in patients with T2DM are progressively decreasing toward the target goals set by the American Diabetes Association. These improvements in metabolic regulation have led to a 30-40% decrease in reported microvascular and macrovascular complications of diabetes mellitus in the USA. Gastric bypass surgery in morbidly obese individuals with T2DM leads to remission of the diabetes mellitus in the majority of patients and improvement in the rest. A major contributor to this improvement is an alteration in gastrointestinal hormone secretions. Interventional surgery might, therefore, be considered a reasonable therapeutic alternative for overweight and obese (BMI <35 kg/m²) patients with T2DM who do not respond to medical therapy.

Abstract
Background. Calcium malabsorption after bariatric surgery may be harmful to skeletal health and demands for optimal skeletal management. Methods. 103 Patients were evaluated retrospectively at 12 months after surgery. The evaluation included a questionnaire about stool frequency and consistency and laboratory assessments. Results. 103 Patients, 27 males and 76 females, were included in the study. 83 Patients had an alimentary limb of 100 cm and 20 patients one of 150 cm. At 12 months after surgery, 77.7% reported changes of bowel habits, albumin adjusted calcium levels were normal in all but 2 patients, and PTH levels were increased in 35%. Correlations between semiquantified bowel scores (fecal scores) and data from the laboratory demonstrated increasing PTH values along with more frequent and softer/watery stools (RR 30.5, CI 6.2-149.2, P < .001). There was a trend for higher PTH levels in patients with an alimentary limb of 150 cm. Normal PTH levels were more frequently found in case of calcium and vitamin D3 use (RR 14.3, CI 3.6-56.5, P < .001). Conclusion. This study demonstrates interrelationships between semi-quantified fecal scores, PTH levels, and the compliance of taking calcium/vitamin D3 suppletion. However, prospective randomized studies are necessary to show causal relationships.

Abstract
OBJECTIVE To evaluate the long-term results of laparoscopic vertical banded gastroplasty (VBG) for morbid obesity. BACKGROUND Laparoscopic VBG, a safe and straightforward bariatric procedure characterized by good short-term results, has been progressively replaced by other more complex procedures on the basis of a presumed high rate of long-term failure. Nevertheless, some authors have recently reported long-term efficacy in selected patients. METHODS All patients who underwent laparoscopic VBG were included in a prospective database. Patients reaching 10-year follow-up received a complete evaluation including clinical, endoscopic, and biochemical examinations. RESULTS Between January 1996 and March 1999, 266 morbidly obese patients underwent bariatric procedures. Among them, 213 were selected for laparoscopic VBG; exclusion criteria were as follows: contraindications to pneumoperitoneum, gastroesophageal reflux disease, and psychological contraindications to restrictive procedures. Mean age, preoperative weight, and body mass index were 36.9 years, 123.6 kg, and 45.4 kg/m, respectively. Intraoperative complication rate and conversion rate were 0.9% and 0.9%, respectively. Early postoperative complication rate was 4.2% and early reoperation rate was 0.5%. Mean hospital length of stay was 6.3 days. Mortality was nil. The 10-year follow-up rate was 70.4% (150 patients). Late postoperative complication rate was 14.7%, and 10-year revisional surgery rate was 10.0%. The excess weight loss percentages at 3, 5, and 10 years were 65.0%, 59.9%, and 59.8%, respectively. The resolution and/or improvement rate for comorbidity were 47.5% for hypertension, 55.6% for diabetes, 75% for sleep apnea, and 47.4% for arthritis. Mean Moorehead-Ardelt Quality of Life Questionnaire and BAROS values were 1.4 and 3.8, respectively. CONCLUSIONS The present study demonstrates that laparoscopic VBG in carefully selected patients leads to long-term results comparable with more complex and invasive procedures. Given the low postoperative morbidity for laparoscopic VBG, its present clinical role should be, in our opinion, reevaluated.

Abstract
The National Longitudinal Study of Adolescent Health and the National Health and Nutrition Examination Survey reported that over 40% of the US population is overweight. The average weight loss attained by medical management programs is neither sufficient nor durable enough to treat medically complicated obesity. An estimated 220,000 bariatric procedures are performed yearly in the USA and Canada. The divided Roux-en-Y gastric bypass (RYGB) is performed most commonly in these countries and is considered the gold standard bariatric surgical procedure. The complexity of RYGB means that serious and potentially preventable perioperative complications can occur. RYGB alters the normal anatomy and physiology of the upper gut, which has predictable adverse effects and potential complications. Patients seek advice and care for symptoms that develop or persist after RYGB; although some symptoms are expected and predictable, others are complications that may or may not require active medical or surgical intervention. Physicians should be able to predict and manage most postoperative medical and nutritional disorders related to RYGB and should be prepared to assess patients for potential referral for surgical intervention or revision.

Abstract
It has been estimated that approximately 220,000 people with morbid obesity underwent bariatric surgery in 2008. Modification of the gastrointestinal tract affects absorption and health care professionals counseling bariatric patients need to be aware of possible micronutrient deficiencies and their symptoms. A systematic review of several databases and bariatric surgery center websites on the Internet was conducted from January 1980 to July 2009 to identify literature related to micronutrient deficiencies occurring after bariatric surgery. Keywords used individually or in combination were bariatric surgery, obesity, vitamin/mineral deficiencies, altered gastrointestinal function, nutrient absorption, nutrient supplementation, and metabolic complications, and were variously combined in the search list. Based on this review, all patients scheduled for bariatric surgery should receive daily multivitamin and multitrace mineral supplements. The literature suggests that bariatric surgery patients are at risk for deficiency of the following nutrients after surgery: vitamins B(12), B(1), C, folate, A, D, and K, along with the trace minerals iron, selenium, zinc, and copper. Over-the-counter multivitamin and mineral supplements do not provide adequate amounts of certain nutrients such as vitamin B(12), iron, or fat-soluble vitamins and patients will require additional doses of prophylactic supplementation life-long to maintain optimal micronutrient status. In addition, preconception care for adequate prenatal supplementation is critical for pregnant women who have undergone bariatric surgery, as iron, vitamin A, vitamin B(12), vitamin K, and folate deficiencies are associated with maternal and fetal complications, including severe anemia, congenital abnormalities, low birth weight, and failure to thrive. All bariatric surgery patients would be best served by receiving regular monitoring of serum nutrient levels starting at 3 mo after surgery and periodically thereafter.

Abstract
Between 1998 and 2004, the total number of bariatric procedures increased almost 10-fold, from 13,386 procedures in 1998 to 121,055 in 2004. Current estimates suggest the number of bariatric operations will exceed 220,000 in 2010. Bariatric surgery encompasses several surgical techniques classified as restrictive or malabsorptive, based on the main mechanism of weight loss. Clinical studies and meta-analyses show that bariatric surgery decreases morbidity and mortality when compared with nonsurgical treatments. A successful long-term outcome of bariatric surgery is dependent on the patient's commitment to a lifetime of dietary and lifestyle changes. The registered dietitian (RD) is an important member of the bariatric team and provides critical instructions to help patients adhere to the dietary changes consistent with surgery. Referencing current literature, this article outlines the indications, contraindications, and types of bariatric surgery. The role of the RD for preoperative and postoperative nutrition assessment and medical nutrition therapy is highlighted. Management of long-term nutrition issues is also reviewed. The current recommendations include a multivitamin/mineral supplement plus vitamin B-12, calcium, vitamin D-3, iron, and folic acid. Given the increasing prevalence of obesity and bariatric surgery procedures, caring for patients who have undergone surgery will be an expanding role for the RD. Close postoperative follow-up and careful monitoring will improve the odds for successful surgical outcomes, and RDs play a very important part in this process.

Abstract
INTRODUCTION Roux-en-Y gastric bypass (RYGB) restricts food intake. Consequently, patients consume less calcium. In addition, food no longer passes through the duodenum, the main site of calcium absorption. Therefore, calcium absorption is significantly impaired. The goal of this study is to compare two common calcium supplements in gastric bypass patients. METHOD Nineteen patients were enrolled in a randomized, double-blinded, crossover study comparing the absorption of calcium from calcium carbonate and calcium citrate salts. Serum and urine calcium levels were assessed for peak values (C (max)) and cumulative calcium increment (area under the curve [AUC]). Serum PTH was assessed for minimum values (PTH(min)) and cumulative PTH decrement (AUC). Statistical analysis was performed using a repeated analysis of variance model. RESULTS Eighteen subjects completed the study. Calcium citrate resulted in a significantly higher serum C (max) (9.4 + 0.4 mg/dl vs. 9.2 + 0.3 mg/dl, p = 0.02) and serum AUC (55 + 2 mg/dl vs. 54 + 2 mg/dl, p = 0.02). Calcium citrate resulted in a significantly lower PTH(min) (24 + 11 pg/ml vs. 30 + 13 pg/ml, p = 0.01) and a higher AUC (-32 + 51 pg/ml vs. -3 + 56 pg/ml, p = 0.04). There was a non-significant trend for higher urinary AUC in the calcium citrate group (76.13 + 36.39 mg/6 h vs. 66.04 + 40.82, p = 0.17). CONCLUSION Calcium citrate has superior bioavailability than calcium carbonate in RYGB patients.
