Surg Obes Relat Dis 2024; 20:407-412. [PMID: 38158312 DOI: 10.1016/j.soard.2023.10.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 07/18/2023] [Accepted: 10/29/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND Current evidence recommends dietary counselling with a registered dietitian (RD) for successful weight loss after metabolic bariatric surgery; however, there are limited data on the effect of RD follow-ups on micronutrient deficiencies. This study evaluated the effects of the number of postoperative RD visits on nutritional outcomes, including weight loss and micronutrient deficiencies. OBJECTIVES The aim of this study was to evaluate the effects of the number of postoperative registered dietitian visits on nutritional outcomes, including weight loss and micronutrient deficiencies after metabolic and bariatric surgery. SETTING Cleveland Clinic Abu Dhabi, United Arab Emirates METHODS: This retrospective study included patients who underwent bariatric surgery between September 2015 and June 2020. Demographics, weight loss, micronutrients, and the number of postoperative RD visits were evaluated. Baseline and 12-month postsurgery outcomes were compared based on the number of RD follow-ups. RESULTS A total of 174 primary and 46 revisions were included. Patients were 73.6% female, with a mean age of 40 years. The initial mean body mass index was 42.8 kg/m2. Number of RD visits were as follows: 0-1 (39 patients), 2 (59 patients), 3 (55 patients), and 4 or more (67 patients). Baseline (pre-operative) micronutrient values were within normal range. In comparison with the reference group (REF = 0-1 post-op RD visits), patients with 3 RD visits had 7% higher total body weight loss (P < .001) and maintained micronutrients within the normal range at 12 months postoperative. Mean differences in postoperative values were statistically significant (P < .05) for weight, vitamin B12, and vitamin D but not for hemoglobin, ferritin, calcium, folate, vitamin B1, copper, and zinc. CONCLUSION Our study suggests that three or more RD visits during the first 12 months after bariatric surgery are associated with improved outcomes, including significant percent total body weight loss and lower rates of micronutrient deficiencies.

Abstract
The purpose of this systematic review was to determine if in patients presenting for bariatric surgery, patients of different ethnicities, have different micronutrient deficiencies preoperatively. Databases searched were PubMed, Embase, MEDLINE and Cochrane Library. A meta-analysis of prevalence of vitamin D insufficiency (<20ng/ml) was carried out using a random effects model. Twenty-eight articles were included assessing preoperative micronutrient status across different ethnic groups. The most common micronutrient assessed was vitamin D, and the most assessed ethnicity was Caucasian. African Americans had the greatest prevalence of vitamin D insufficiency when compared to other ethnicities with a pooled prevalence and 95% confidence interval of 0.80 [0.74; 0.85]. There was a significant difference in vitamin D insufficiency when compared across ethnicities (p <0.01).

Abstract
BACKGROUND Micronutrients, an umbrella term used to collectively describe vitamins and trace elements, are essential components of nutrition. Those requiring alternative forms of nutrition support are dependent on the prescribed nutrition regimen for their micronutrient provision. The purpose of this paper is to assist clinicians to bridge the gap between the available guidelines' recommendations and their practical application in the provision of micronutrients via the parenteral route to adult patients. METHODS Based on the available evidenced-based literature and existing guidelines, a panel of multidisciplinary healthcare professionals with significant experience in the provision of parenteral nutrition (PN) and intravenous micronutrients developed this international consensus paper. RESULTS The paper addresses 14 clinically relevant questions regarding the importance and use of micronutrients in various clinical conditions. Practical orientation on how micronutrients should be prescribed, administered, and monitored is provided. CONCLUSION Micronutrients are a critical component to nutrition provision and PN provided without them pose a considerable risk to nutrition status. Obstacles to their daily provision-including voluntary omission, partial provision, and supply issues-must be overcome to allow safe and responsible nutrition practice.

Abstract
The essential trace element zinc (Zn) plays a key role in the development, differentiation and growth of various human tissues. Zinc homeostasis is primarily regulated by two zinc transporter families (solute-linked carrier families, SLC). Disturbances in zinc metabolism may give rise to disorders that typically manifest themselves on the skin. An autosomal recessive zinc deficiency disorder, acrodermatitis enteropathica is caused by a mutation in the gene coding for the ZIP4 transporter. Due to intestinal malabsorption, affected infants develop clinical signs and symptoms shortly after weaning. Acquired zinc deficiency is a rare but underdiagnosed disorder associated with various etiologies and variable clinical manifestations. Depending on the patient's age, a multitude of causes have to be considered. Given the characteristic periorificial and acral lesions, the clinical diagnosis is usually made by dermatologists. Laboratory confirmation includes measurement of plasma zinc levels and - as a supplementary measure - zinc-dependent enzymes such as alkaline phosphatase. Oral zinc replacement therapy frequently leads to clinical remission within a few days. Depending on the cause, disease management should include cooperation with pediatricians and gastroenterologists in order to guarantee optimal patient care.

Abstract
BACKGROUND & AIMS Roux-en-Y gastric bypass (RYGB) is associated with an increased risk for micronutrient deficiencies. This study aimed to assess total (dietary and supplement) intake and association with iron (including hepcidin), vitamin B12, vitamin C and zinc status markers before and after Roux-en-Y gastric bypass (RYGB). METHODS This prospective study included patients with a planned RYGB in University Hospitals Leuven, Belgium; who were followed until 12 months post-RYGB. Patients completed an estimated dietary record of two non-consecutive days before and 1, 3, 6 and 12 months post-RYGB and supplement/drug use was registered. Associations between total micronutrient intake and status markers were analyzed. RESULTS Fifty-four patients (21 males; mean age: 48.0 [95%CI 46.6; 49.3] years; mean preoperative BMI: 40.4 [95%CI 39.4; 41.4] kg/m2) were included. One month post-RYGB, usual dietary intake of the studied micronutrients was significantly decreased compared to pre-RYGB, but gradually increased until 12 months post-RYGB, remaining below baseline values. By including micronutrient supplement intake, 12 months post-RYGB values were higher than baseline, except for zinc. Hemoglobin, ferritin, vitamin B12 and C-reactive protein serum concentrations were significantly decreased and transferrin saturation and mean corpuscular volume were significantly increased 12 months post-RYGB. Serum hepcidin concentration was significantly decreased 6 months post-RYGB. CONCLUSIONS Medical nutritional therapy is essential following RYGB as dietary intake of iron, vitamin B12, vitamin C, copper and zinc was markedly decreased postoperatively and some patients still had an inadequate total intake one year post-RYGB.

Abstract
BACKGROUND Bariatric surgery is associated not only with weight loss and improvement of comorbidities of obesity but also with short and long-term complications. Preoperative screening and lifelong follow-up of these patients are important to optimize the effect of bariatric surgery and minimize complications. The objective of this study was to create an inventory of the current care offered to bariatric patients before and after surgery in Flemish hospitals, Belgium and to identify barriers for optimal care. METHODS Semi-structured interviews with healthcare professionals involved in screening and follow-up of bariatric patients in 12 hospitals in Flanders, Belgium were performed. Interviews were transcribed verbatim and analyzed with NVivo 10.0. RESULTS In each participating hospital, except one, biochemical screening before and after bariatric surgery was performed, but the extent and timing varied between hospitals. In ten hospitals, a standard multivitamin preparation was started in all patients after surgery, but there was a large variation for timing of initiation and duration between hospitals. The interviewees indicated that the knowledge about appropriate dosage and formulation adjustments after surgery was limited. Most of the performed drug adjustments were due to improvement of comorbidities. In 9 out of 12 hospitals, a multidisciplinary team was involved, but the approach varied widely. Only in 3 out of 12 hospitals, eligibility of patients for bariatric surgery was discussed in team meetings. CONCLUSIONS Strategies to implement existing guidelines are required in order to obtain more uniform, interdisciplinary support for bariatric patients, resulting in an increase of efficiency of surgery and improved patient care.

Abstract
We provide a practical approach to the complex management problem of chyle leaks that occur after surgical procedures or trauma, or when they occur spontaneously in association with malignancies. The volume of chyle loss causes significant problems due to loss of fluid, electrolytes, proteins, and lymphocytes, causing deleterious effects on wound healing and immunity. Enteral feeding is not always possible as long chain fatty acids are absorbed through the intestinal lacteals, the original source of chyle. Regular diets increase the leak and delay healing. Nutritional support involves coordinated care between healthcare providers to provide a combination of various modalities, including nil by mouth, parenteral nutrition, enteral feeding with formula modifications, and oral diet.

Abstract
Pregnant and postpartum women with a history of bariatric surgery are at risk of micronutrient deficiencies as a result of the combination of physiologic changes related to pregnancy and iatrogenic postoperative alterations in the absorption and metabolism of crucial nutrients. This systematic review investigates micronutrient deficiencies and related adverse clinical outcomes in pregnant and postpartum women after bariatric surgery. A systematic approach involving critical appraisal was conducted independently by 2 researchers to examine deficiencies of phylloquinone, folate, iron, calcium, zinc, magnesium, iodide, copper, and vitamins A, D, and B-12 in pregnant and postpartum women after bariatric surgery, together with subsequent outcomes in the neonates. The search identified 29 relevant cases and 8 cohort studies. The quality of reporting among the case reports was weak according to the criteria based on the CARE (CAse REporting) guidelines as was that for the cohort studies based on the criteria from the Cohort Study Quality Assessment list of the Dutch Cochrane Center. The most common adverse neonatal outcomes related to maternal micronutrient deficiencies include visual complications (vitamin A), intracranial hemorrhage (phylloquinone), neurological and developmental impairment (vitamin B-12), and neural tube defects (folate). On the basis of the systematically collected information, we conclude that the evidence on micronutrient deficiencies in pregnant and postpartum women after bariatric surgery and subsequent adverse neonatal outcomes remains weak and inconclusive.

Abstract
The essential trace element zinc (Zn) has a large number of physiologic roles, in particular being required for growth and functioning of the immune system. Adaptive mechanisms enable the body to maintain normal total body Zn status over a wide range of intakes, but deficiency can occur because of reduced absorption or increased gastrointestinal losses. Deficiency impairs physiologic processes, leading to clinical consequences that include failure to thrive, skin rash, and impaired wound healing. Mild deficiency that is not clinically overt may still cause nonspecific consequences, such as susceptibility to infection and poor growth. The plasma Zn concentration has poor sensitivity and specificity as a test of deficiency. Consequently, diagnosis of deficiency requires a combination of clinical assessment and biochemical tests. Patients receiving parenteral nutrition (PN) are susceptible to Zn deficiency and its consequences. Nutrition support teams should have a strategy for assessing Zn status and optimizing this by appropriate supplementation. Nutrition guidelines recommend generous Zn provision from the start of PN. This review covers the physiology of Zn, the consequences of its deficiency, and the assessment of its status, before discussing its role in PN.

Abstract
BACKGROUND Obesity is a chronic disease with high growth in population and bariatric surgery is currently considered the most effective treatment for weight reduction; on the other hand, nutritional deficiencies are observed after this procedure. AIM To analyze weight loss progression and nutritional anemia in patients submitted to Roux-en-Y gastric bypass on use of vitamin and mineral supplementation. METHODS Retrospective analysis of 137 patients of both sexes, aged between 18-60 years, using supplemental multivitamins and minerals, were included; personal information, anthropometric and laboratory data in the preoperative, 12, 24, 36 and 48 months postoperatively were collected. RESULTS Postoperatively, in both sexes, occurred weight loss compared to the pre-operative weight gain at 48 months and maintenance of body mass index. There was a decrease in the percentage of excess weight loss at 48 months postoperatively compared to the time of 12, 24 and 36 months in men and decreased at 48 postoperative months compared to the time of 24 months in females. There was a decreased in serum ferritin in both sexes and increased serum iron at 48 months postoperatively in males. There was a decreased in vitamin B12 and folic acid increased serum at 48 postoperative months in females. CONCLUSIONS Surgical treatment was effective for reducing weight, body mass index reduction and achievement of success in the late postoperative period along with multivitamin and mineral supplementation on prevention of serious nutritional deficiencies and anemia.

The relationship between immediate preoperative serum 25-hydroxy-vitamin D₃ levels and cardiac function, dysglycemia, length of stay, and 30-d readmissions in cardiac surgery patients. Nutrition 2014; 31:820-6.

Abstract
OBJECTIVES Vitamin D has pleiotropic effects on cardiac, renal, and endocrine diseases like diabetes mellitus and deficiency has been correlated with increased Intensive Care Unit (ICU) morbidity and mortality. We studied the relationship between preoperative Vitamin D levels and several short-term endpoints including cardiovascular events, glucose levels, ICU, and hospital length of stay. METHODS Standard demographic data were obtained. Blood samples were drawn for 25-hydroxy-vitamin D3 (Vit D) levels at baseline (just before induction of anesthesia) and on postoperative day (POD #1). The number of inotropes used on POD # 0, 1, and 2 was recorded as well as the Cardiac Index (CI). Baseline glucose, Blood Urea Nitrogen and Creatinine (Cr) levels were obtained and repeated on POD # 1 & 2. Other variables studied are number of days of ICU and hospital stay. RESULTS Of the 64 patients included in the cohort, 3 were excluded because of inadequate data. 69% had Vit D levels <20 ng/mL and 31% had levels ≥20 ng/mL. More than 90% of the cohort had a significant decrease in POD # 1 Vit D levels (P < 0.001). Age, sex, race, and body mass index did not predict the preoperative Vit D levels; however, the timing of surgery was associated with preoperative Vit D levels, lowest in subjects who had surgery performed during winter. Preoperative Vit D levels had no effect on postoperative glycemic control, cardiac index, or composite outcome-arrhythmias, respiratory failure, or prolonged inotropic support. On regression analysis, preoperative Vit D levels did show a significant effect on ICU and hospital length of stay in this cohort. CONCLUSIONS The low levels in this study truly represent the Vit D status as they were obtained before any intervention, including surgery or fluid administration. Vit D levels decreased rapidly after surgery and hence future studies on Vit D may need to focus on premorbid levels obtained at the time of initial presentation and not those obtained after resuscitation or ICU admission. In contrast to epidemiologic reports, we found no association between low Vit D levels and postoperative cardiovascular events. However, low Vit D levels did affect the ICU and hospital length of stay in patients who were undergoing cardiac surgery. This is an important finding especially when many institutions and regulatory agencies are investigating novel therapies and processes to reduce the length of hospitalization. More studies are required to investigate the effect on hospital length of stay of early preadmission or preoperative Vit D supplementation before elective surgery.

Abstract
Background Studies report frequent micronutrient deficiencies after bariatric surgery, but less is known about micronutrient levels of pregnant women after bariatric surgery. Objective To prospectively evaluate micronutrient levels and supplement intake in pregnancy following bariatric surgery. Design A multicenter prospective cohort study including women with restrictive or malabsorptive types of bariatric surgery. Nutritional deficiencies, together with supplement intake, were screened during pregnancy. Results The total population included 18 women in the restrictive and 31 in the malabsorptive group. Most micronutrients were depleted and declined significantly during pregnancy. The proportion of women with low vitamin A and B-1 levels increased to respectively 58 and 17% at delivery (P = 0.005 and 0.002). The proportion of women with vitamin D deficiency decreased from 14% at trimester 1 to 6% at delivery (P = 0.030). Mild anemia was found in respectively 22 and 40% of the women at trimester 1 and delivery. In the first trimester, most women took a multivitamin (57.1%). In the second and third trimester, the majority took additional supplements (69.4 and 73.5%). No associations were found between supplement intake and micronutrient deficiencies. Conclusion Pregnant women with bariatric surgery show frequent low micronutrient levels. Supplementation partially normalizes low levels of micronutrients.

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
INTRODUCTION Data already demonstrated the increased prevalence of obesity in various segments of the population. In this context, bariatric surgery is accepted nowadays as the most effective tool in the treatment and control of morbid obesity. Several studies have evaluated the nutritional status after bariatric surgery, especially mixed by detecting a reduction in food intake of protein, vitamins and minerals. However, other studies have investigated the presence of nutritional deficiencies prior to surgery, which may be aggravated by the surgical procedure, resulting in serious postoperative complications. AIM To analyze the literature in relationship to micronutrient deficiencies in obese patients before bariatric surgery. METHOD Was carried out a systematic review in several electronic databases, such as PubMed/ Medline, Scielo, Lilacs and Bireme. The following keywords were used alone or in combination: bariatric surgery, obesity, preoperative, gastric bypass, vitamin deficiencies, deficiencies and mineral nutrient absorption. Were included 40 review and original articles published between 2005 to 2012. RESULTS There were consensus on the combination of preoperative nutritional deficiencies, restrictions and malabsorption, possibly induced by bariatric surgery that can lead patients to experience significant nutritional deficits during the late postoperative period, especially of micronutrients, resulting in serious complications. CONCLUSIONS The high occurrence of micronutrient deficiencies preoperatively detected in morbidly obese candidates for bariatric surgery, plus a malabsorptive procedure, may involve worse prognosis during the late postoperative period. Preoperative evaluation of nutritional parameters and food intake is recommended in conjunction with surgical interventions.

Abstract
BACKGROUND Patients with chronic pancreatitis are at risk of malnutrition and nutrient deficiency due to malabsorption, pain, and poor diet. We sought to examine fat-soluble vitamin levels and malnutrition parameters in patients with chronic pancreatitis. MATERIALS AND METHODS In a prospective controlled cohort study, 128 subjects (62 chronic pancreatitis patients and 66 age-/sex-matched controls) were recruited. Body mass index (BMI), handgrip strength (measure of functional capacity), fat stores (triceps skin fold), muscle stores (mid-arm muscle circumference), exocrine function, and serum levels of fat-soluble vitamins (A, D, E) were measured. RESULTS Half of patients in the chronic pancreatitis group were overweight or obese, although the mean BMI was lower in patients than in controls (P = .007). Handgrip strength (P = .048), fat stores (P = .000), and muscle stores (P = .001) were lower in patients than in controls. Of the patients, 14.5% and 24.2% were deficient in vitamins A and E, respectively. Nineteen percent of patients had excess serum vitamin A levels. CONCLUSIONS Despite the prevalence of overweight and obesity, patients had lower muscle stores, strength, and abnormal vitamin levels. Detailed nutrition assessment including anthropometry and vitamin status is warranted in chronic pancreatitis.

Abstract
One of the most important factors affecting outcome and recovery from surgical trauma is preoperative nutritional status. Research in perioperative nutritional support has suffered from a lack of consensus as to the definition of malnutrition, no recognition of which nutrients are important to surgical healing, and a paucity of well-designed studies. In the past decade, there has been some activity to address this situation, recognizing the importance of nutrition as a therapy before surgery, after surgery, and possibly even during surgery.

Cross-sectional long-term micronutrient deficiencies after sleeve gastrectomy versus Roux-en-Y gastric bypass: a pilot study. Surg Obes Relat Dis 2013; 10:262-8.

Abstract
BACKGROUND Nutritional deficiencies are highly prevalent in obese patients. Bariatric surgery has been associated with adverse effects on homeostasis of significant vitamins and micronutrients, mainly after gastric bypass. The aim of the present study was to compare the extent of long-term postsurgical nutritional deficiencies between Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). METHODS This cross-sectional, pilot study included 95 patients who underwent RYGB or SG surgery with a mean follow-up of 4 years. Demographic, anthropometric, and biochemical parameters were compared according to the type of surgery. RESULTS Both types of surgery were associated with significant nutritional deficiencies. Vitamin B12 deficiency was significantly higher in patients with RYGB compared with SG (42.1% versus 5%, P = .003). The type of surgery was associated neither with anemia nor with iron or folate deficiency (SG versus RYGB: anemia, 54.2% versus 64.3%, P = .418; folate deficiency, 20% versus 18.4%, P = .884; iron deficiency, 30% versus 36.4%, P = .635). CONCLUSION During a mean follow up period of 4 years postRYGB or SG, patients were identified with several micronutrient deficiencies, including vitamin D, folate, and vitamin B12. SG may have a more favorable effect on the metabolism of vitamin B12 compared with RYGB, being associated with less malabsorption. Adherence to supplemental iron and vitamin intake is of primary significance in all cases of bariatric surgery.

Abstract
OBJECTIVE To evaluate bone turnover markers and bone mineral density (BMD) in women after Roux-en-Y (RYGB) gastric bypass. SUBJECTS AND METHODS In a cross-sectional study, 48 women post-RYGB after three years, and 41 healthy women were evaluated. EVALUATIONS body mass index (BMI); physical activity; food intake; serum levels of calcium, phosphorus, magnesium, alkaline phosphatase, C-terminal telopeptide (CTX), intact parathyroid hormone (PTH), 25-hydroxyvitamin D (25OHD), osteocalcin, urinary calcium and BMD. RESULTS Significantly higher levels were observed for osteocalcin (p < 0.001), CTX (p < 0.001), and PTH (p < 0.001) in the RYGB group when compared with the control group; 25OHD deficiency/insufficiency was more frequent in the RYGB group (p = 0.010), even after adjusted for nutritional status, and it was associated with secondary hyperparathyroidism (p = 0.025); there was no difference in BMD between the groups. Energy (p = 0.036) and protein intake (p = 0.004) were lower in the RYGB group. CONCLUSION Patients submitted to RYGB showed a significantly higher frequency of vitamin D deficiency, secondary hyperparathyroidism, and increase in bone remodeling markers, with no difference in BMD status.

Abstract
Clinicians involved with nutrition therapy traditionally concentrated on macronutrients and have generally neglected the importance of micronutrients, both vitamins and trace elements. Micronutrients, which work in unison, are important for fundamental biological processes and enzymatic reactions, and deficiencies may lead to disastrous consequences. This review concentrates on vitamin B(1), or thiamine. Alcoholism is not the only risk factor for thiamine deficiency, and thiamine deficiency is often not suspected in seemingly well-nourished or even overnourished patients. Deficiency of thiamine has historically been described as beriberi but may often be seen in current-day practice, manifesting as neurologic abnormalities, mental changes, congestive heart failure, unexplained metabolic acidosis, and so on. This review explains the importance of thiamine in nutrition therapy and offers practical tips on prevention and management of deficiency states.
