EClinicalMedicine 2024; 69:102462. [PMID: 38333369 PMCID: PMC10850131 DOI: 10.1016/j.eclinm.2024.102462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 01/17/2024] [Accepted: 01/17/2024] [Indexed: 02/10/2024] Open
Abstract
Background Childhood obesity is a pressing health crisis of epidemic proportions. Bariatric surgery (BS) is an effective weight loss solution however its role in the paediatric population is contentious owing to the paucity of weight specific and generalised health outcomes. This systematic review and meta-analysis aimed to assess the impact of paediatric BS on bone health. Methods This prospectively registered systematic review (PROSPERO ID: CRD42023432035) was performed in accordance with PRISMA guidelines. We searched MEDLINE (1946-1928 September 2023), EMBASE (1947-1928 September 2023) via the Ovid platform, and the Cochrane Review Library to identify scientific publications reporting bone outcome measures in patients under the age of 18 years who underwent BS. Meta-analysis was undertaken on post-operative weight and bone parameters in paediatric patients following BS. Outcomes were reported as weighted or standardized mean difference with 95 percent confidence intervals. Subgroup analysis by intervention, quality scoring and risk of bias were assessed. Findings Twelve studies with 681 patients across 5 countries (mean age 17 ± 0.57 years) were included. The quality of included studies was rated as high and there was substantial between-study heterogeneity for most factors included in the meta-analysis (I2 from 0% to 99.1%). Patients underwent Roux-en-Y gastric bypass (RYGB, n = 216), sleeve gastrectomy (SG, n = 257), gastric band (n = 184) or intragastric balloon placement (n = 24). BS was associated with significant weight reduction, body mass index (BMI) -12.7 kg/m2 (95% CI -14.5 to -10.9, p < 0.001), with RYGB being most effective, BMI -16.58 kg/m2 (95% CI -19.6 to -13.6, p < 0.001). Patients who underwent SG or RYGB had significantly lower lumbar bone mineral density, -0.96 g/cm2 (95% CI -0.1 to -0.03, p < 0.001), Z score, -1.132 (95% CI -1.8 to -0.45, p < 0.001) and subtotal body bone mineral density, -0.7 g/cm2 (95% CI -1.2 to -0.2, p < 0.001) following surgery. This was accompanied with higher markers of bone resorption, C-terminal telopeptide of type 1 collagen 0.22 ng/ml (95% CI 0.12-0.32, p < 0.001) and osteocalcin, 10.83 ng/ml (95% CI 6.01-15.67, p < 0.001). There was a significant reduction in calcium levels following BS, -3.78 mg/dl (95% CI -6.1 to -1.5, p < 0.001) but no difference in 25-hydroxyvitamin D, phosphate, bone alkaline phosphatase, procollagen type 1 N propeptide or parathyroid hormone. Interpretation BS effectively reduces weight in paediatric patients, but RYGB and SG may have adverse effects on bone health in the medium term. It is crucial to monitor and support bone health through appropriate nutritional supplementation and judicious follow-up. Long-term data is needed to fully understand the clinical implications of these findings on bone outcomes. Funding Medical Research Council (MRC), United Kingdom.

Abstract
Hypocalcemia following thyroidectomy is a common and potentially life-threatening complication. It is caused by intraoperative injury to the parathyroid glands or their blood supply. Although several studies have shown that patients with a prior history of bariatric surgery may be at an increased risk for hypocalcemia after thyroidectomy, no clear recommendations exist for preventing and managing this condition in this population. This paper highlights the significance of understanding this risk and of obtaining a history of prior bariatric surgery before thyroidectomy. We propose concise recommendations for preventing and managing hypocalcemia following thyroidectomy in patients with a history of bariatric surgery.

Abstract
PURPOSE OF REVIEW Single anastomosis duodenoileal bypass with sleeve (SADI-S) is a recently endorsed metabolic and bariatric surgery (MBS) procedure in the US. Despite its favorable characteristics, the utilization of SADI-S remains limited, accounting for a mere 0.25% of all MBS procedures performed. This review aims to offer an updated examination of the technique, while also presenting the safety and outcomes associated with SADI-S on both the short and long term. RECENT FINDINGS The safety of SADI-S is well-established, with short-term complication rates as low as 2.6%. A common channel length of 300 cm has consistently shown a lower incidence of malabsorption complications compared to shorter lengths. Bile reflux after SADI-S is relatively rare with an incidence of only 1.23%. SADI-S demonstrated sustained total weight loss (%TWL) at 5 years (37%) and 10 years (34%) postoperatively. Resolution of weight-related medical conditions was also significant after SADI-S, with remission rates of diabetes mellitus as high as 86.6% with over 5 years of follow-up. SADI-S is a safe and effective MBS procedure that has shown impressive and sustainable results in terms of weight loss and improvement in obesity-related medical conditions. Careful limb length selection is essential in minimizing the risk of nutritional deficiencies. SADI-S holds great promise as a valuable option for individuals seeking effective weight loss and improvement in associated health conditions.

Abstract
Micronutrient deficiencies may develop as a long-term complication of bariatric surgery due to alteration of gut anatomy and disruption of normal gut absorption. Inadequate repletion of essential vitamin and mineral deficiencies can lead to multisystem dysfunction. We present a case of a woman in her 50s, with a history of Roux-en-Y gastric bypass over 10 years ago, who presented with generalised weakness and a diffuse desquamating rash. A punch biopsy performed was compatible with nutritional deficiency. Labs revealed low levels of micronutrients A, B1, B6, C, E, zinc and copper. The patient received intravenous micronutrients and an oral regimen, which improved her symptoms. Unfortunately, the patient died from cardiac arrest secondary to pulmonary oedema. This report highlights the importance of high suspicion of micronutrient deficiency in patients with a history of bariatric surgery and maintaining lifelong nutritional follow-up.

Abstract
BACKGROUND The risk of protein and vitamin deficiencies after bariatric surgery has been well studied, but the change in mineral status has not gotten enough attention. This study aimed to perform a meta-analysis regarding the change in mineral levels after bariatric surgery and the prevalence of postoperative mineral deficiency, with subgroup analyses of different surgical procedures, study regions, and follow-up time. METHODS CENTRAL, PubMed, and EMBASE were searched for related articles. Meta-analysis, subgroup analysis, and sensitivity analysis were performed if necessary. RESULTS A total of 107 articles with 47,432 patients were included. The most severe mineral deficiency after bariatric surgery was iron (20.1%), followed by zinc (18.3%), copper (14.4%), chlorine (12.2%), phosphorus (7.5%), and calcium (7.4%). Serum concentrations of potassium, sodium, selenium, manganese, and molybdenum showed no significant change before and after surgery. Subgroup analyses revealed that SG had fewer deficiencies in serum iron, calcium, zinc, magnesium, phosphorus, copper, and selenium than RYGB. OAGB showed a higher incidence of serum iron and zinc deficiencies than RYGB. Studies conducted in different regions also found various mineral statuses after surgery. Studies with follow-up ≥ 5 years had a lower prevalence of zinc, copper, and selenium deficiencies than follow-up < 5 years. CONCLUSION A high deficiency rate of serum iron, zinc, copper, chlorine, phosphorus, and calcium was seen after bariatric surgery. The difference in surgical procedures, study regions, and follow-up time may affect postoperative mineral status; more targeted mineral supplement programs are needed considering these influencing factors.

Abstract
AIMS OF THE STUDY Vitamin A deficiency retinopathy is a potentially blinding disease. In developed countries, vitamin A deficiency due to malnutrition is rare. However, vitamin A deficiency can be caused by malabsorption resulting from bowel resection or medication. In this retrospective study, we present five cases of vitamin A deficiency retinopathy related to malabsorption secondary to medical interventions. METHODS Electronic charts over a ten-year period (2012-2022) were screened for vitamin A deficiency retinopathy. Only patients with vitamin A deficiency confirmed by laboratory tests were included. Symptoms, medical history, visual acuity, optical coherence tomography, fundus autofluorescence, electrophysiological examination, and vitamin A levels were reviewed. RESULTS Five eligible cases were identified. Median age was 44.7 years (range 22.2-88.9), median duration of ocular symptoms prior to diagnosis was 14 months, and median visual acuity was 1.0 (range 0.5-1.0, Snellen, decimal). Three patients had a history of bariatric surgery, one patient had a small bowel resection and was on octreotide treatment, and one patient suffered from cystic fibrosis and had a history of small bowel resection and severe hepatopathy. Optical coherence tomography showed various abnormalities, including a reduced interdigitation zone, subretinal drusenoid deposits, and a thinned outer nuclear layer. Electroretinogram findings ranged from abnormal oscillatory potentials to non-recordable rod responses. CONCLUSIONS Vitamin A deficiency retinopathy can occur following medical interventions associated with malabsorption. In cases of night blindness, vitamin A levels should be measured.

Abstract
Vitamin A, also known as retinol, is a non-water-soluble vitamin. Vitamin A is very important for the proper functioning of the human body. Retinol, especially in the form of retinyl ester, can be found in many animal-based products and is essential for the efficient operation of many physiological processes. Fruits and vegetables are also excellent sources of vitamin A; the majority of them include carotenoids, which are precursors to vitamin A. The human body has the ability to convert natural retinols like retinyl ester, retinoic acid, and provitamin A into biologically active forms that interact with a variety of molecular targets like nuclear receptors and retinal opsins. This review article provides knowledge regarding retinol deficiency in humans. It provides brief information about the sources, etiology, epidemiology, pathophysiology, and treatment of vitamin A deficiency.

Abstract
Retinitis pigmentosa (RP) displays a broad range of phenotypic variations, often overlapping with acquired retinal diseases. Timely recognition and differentiation of RP masquerades is paramount due to the treatable nature of many such conditions. This review seeks to present examples of pseudo-RP cases and provide a comprehensive overview of RP masquerades. We first present two pseudo-RP cases, including comprehensive clinical histories and multimodal retinal imaging, to highlight the important role of accurate diagnoses that subsequently steered effective intervention. Subsequently, we conduct an in-depth review of RP masquerades to provide valuable insights into their key distinguishing features and management considerations. The recent approval of ocular gene therapy and the development of investigational gene-based treatments have brought genetic testing to the forefront for RP patients. However, it is important to note that genetic testing currently lacks utility as a screening tool for inherited retinal diseases (IRDs), including RP. The integrity of a precise clinical assessment remains indispensable for the diagnosis of both RP and RP masquerade conditions, thereby facilitating prompt intervention and appropriate management strategies.

Abstract
Bariatric surgery is increasingly used in women of childbearing age due to the rising prevalence of obesity and the effectiveness and availability of this treatment. Pregnancy in women with previous bariatric surgery deserves special attention. Weight loss induced by surgery reduces the risks that obesity poses to pregnancy. But on the other hand, decreased intake and malabsorption may increase the risk of malnutrition and micronutrient deficiency and negatively affect maternal and foetal health. The aim of this narrative review is to provide an updated analysis of the impact of different bariatric surgery techniques on mineral and micronutrient nutritional status during pregnancy and the possible effect on maternal-foetal health.

Abstract
Bariatric surgery is the most effective treatment for sustained weight reduction, and it can result in substantial improvements in the severity of type 2 diabetes, metabolic syndrome, nonalcoholic fatty liver disease, and quality of life. However, sleeve gastrectomy, a weight loss surgery that removes two-thirds of the stomach, reduces appetite and nutrient absorption, impairing digestion and the absorption of nutrients like iron, vitamin B12, and protein-bound nutrients. This case study aims to demonstrate that patients undergoing sleeve gastrectomy require long-term and periodic monitoring of biochemical data, weight changes, and caloric and protein intake by a professional nutritionist to prevent malnutrition and nutritional deficiencies. In this case study, a 48-year-old woman was diagnosed with morbid obesity, hypertension, sleep apnea syndrome, and chronic gastritis. At initial evaluation, she was 160 cm tall and weighed 89 kg, with a body mass index of 34.8 kg/m2. At 1 postoperative year, she consumed 650 kcal and 25 g of protein per day, the percentage of excess weight loss was 141.1%, and body mass index was 21 kg/m2. Compared to preoperative levels, calcium and folic acid levels did not decrease after 1 postoperative year, but hemoglobin, ferritin, and vitamin B12 levels decreased. In conclusion, when patients experience rapid weight loss after sleeve gastrectomy, follow-up should be frequent and long. Dietary education should be conducted according to digestive symptoms, and oral nutritional supplements, including vitamins and minerals.

Abstract
Nutrients, required by human bodies to perform life-sustaining functions, are obtained from the diet. They are broadly classified into macronutrients (carbohydrates, lipids, and proteins), micronutrients (vitamins and minerals) and water. All nutrients serve as a source of energy, provide structural support to the body and/or regulate the chemical processes of the body. Food and drinks also consist of non-nutrients that may be beneficial (e.g., antioxidants) or harmful (e.g., dyes or preservatives added to processed foods) to the body and the ocular surface. There is also a complex interplay between systemic disorders and an individual's nutritional status. Changes in the gut microbiome may lead to alterations at the ocular surface. Poor nutrition may exacerbate select systemic conditions. Similarly, certain systemic conditions may affect the uptake, processing and distribution of nutrients by the body. These disorders may lead to deficiencies in micro- and macro-nutrients that are important in maintaining ocular surface health. Medications used to treat these conditions may also cause ocular surface changes. The prevalence of nutrition-related chronic diseases is climbing worldwide. This report sought to review the evidence supporting the impact of nutrition on the ocular surface, either directly or as a consequence of the chronic diseases that result. To address a key question, a systematic review investigated the effects of intentional food restriction on ocular surface health; of the 25 included studies, most investigated Ramadan fasting (56%), followed by bariatric surgery (16%), anorexia nervosa (16%), but none were judged to be of high quality, with no randomized-controlled trials.

Abstract
The word "elective" refers to medications and procedures undertaken by choice or with a lower grade of prioritization. Patients usually use elective medications or undergo elective procedures to treat pathologic conditions or for cosmetic enhancement, impacting their lifestyle positively and, thus, improving their quality of life. However, those interventions can affect the homeostasis of the tear film and ocular surface. Consequently, they generate signs and symptoms that could impair the patient's quality of life. This report describes the impact of elective topical and systemic medications and procedures on the ocular surface and the underlying mechanisms. Moreover, elective procedures performed for ocular diseases, cosmetic enhancement, and non-ophthalmic interventions, such as radiotherapy and bariatric surgery, are discussed. The report also evaluates significant anatomical and biological consequences of non-urgent interventions to the ocular surface, such as neuropathic and neurotrophic keratopathies. Besides that, it provides an overview of the prophylaxis and management of pathological conditions resulting from the studied interventions and suggests areas for future research. The report also contains a systematic review investigating the quality of life among people who have undergone small incision lenticule extraction (SMILE). Overall, SMILE refractive surgery seems to cause more vision disturbances than LASIK in the first month post-surgery, but less dry eye symptoms in long-term follow up.

Abstract
Our review aimed to assess the effects of bariatric surgery-induced weight loss on ocular functions. We focused on retinochoroidal microcirculation, glaucomatous factors, and the condition of the eye surface pre- and postoperatively. The review covered 23 articles, including five case reports. Bariatric surgery positively impacts retinochoroidal microcirculation. The arterial perfusion and vascular density improve, venules constrict, and the arteriole-to-venule ratio increases. Weight loss positively correlates with intraocular pressure decrease. The impact of postoperative weight loss on the choroidal thickness (CT) and the retinal nerve fiber layer (RNFL) is still unclear. The correlation between ocular symptoms and hypovitaminosis A needs to be evaluated. Further research is required, especially regarding CT and RNFL, mainly focusing on long-term follow-up.

Abstract
INTRODUCTION Single Anastomosis Duodenal-Ileal Bypass with Sleeve Gastrectomy (SADI-S), like other hypoabsorptive procedures, could be burdened by long-term nutritional deficiencies such as malnutrition, anemia, hypocalcemia, and hyperparathyroidism. OBJECTIVES We aimed to report our experience in terms of mid-term (2 years) bariatric, nutritional, and metabolic results in patients who underwent SADI-S both as a primary or revisional procedure. METHODS One hundred twenty-one patients were scheduled for SADI-S as a primary or revisional procedure from July 2016 to February 2020 and completed at least 2 years of follow-up. Demographic features, bariatric, nutritional, and metabolic results were analyzed during a stepped follow-up at 3 months, 6 months, 1 year and 2 years. RESULTS Sixty-six patients (47 female and 19 male) were included. The median preoperative BMI was 53 (48-58) kg/m2. Comorbidities were reported in 48 (72.7%) patients. At 2 years, patients had a median BMI of 27 (27-31) kg/m2 (p < 0.001) with a median %EWL of 85.3% (72.1-96.1), a TWL of 75 (49-100) kg, and a %TWL of 50.9% (40.7-56.9). The complete remission rate was 87.5% for type 2 diabetes mellitus, 83.3% for obstructive sleep apnea syndrome and 64.5% for hypertension. The main nutritional deficiencies post SADI-S were vitamin D (31.82%) and folic acid deficiencies (9.09%). CONCLUSION SADI-S could be considered as an efficient and safe procedure with regard to nutritional status, at least in mid-term (2 years) results. It represents a promising bariatric procedure because of the excellent metabolic and bariatric outcomes with acceptable nutritional deficiency rates. Nevertheless, larger studies with longer follow-ups are necessary to draw definitive conclusions.

Abstract
BACKGROUND Persons submitted to bariatric metabolic surgery present micronutrient deficiency before and after surgery, due to the lack of proper supplementation. The aim of this study is to establish the prevalence of micronutrient deficiency in people before and after bariatric metabolic surgery in Latin America. METHODS This review was conducted in accordance with the 2020 PRISMA Guidelines. RESULTS Twenty-seven studies and 2135 participants were included. The highest prevalence of deficiency before surgery was reported for vitamin D (74%), zinc (71%), and hemoglobin (62%); after surgery, they were vitamin A (90.6%), vitamin D (90%), and zinc (68%). CONCLUSIONS There is a high prevalence of micronutrient deficiency before and after bariatric metabolic surgery from Latin American persons; the micronutrients with the highest deficiency prevalence were vitamin D before and vitamin A after bariatric metabolic surgery.

Abstract
PURPOSE To explain the pathophysiology of kidney stone formation and appropriate dietary recommendations in inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) and Crohn's disease (CD) and after bariatric surgery, focusing on the current literature. METHODS A narrative review methodology was performed. A literature search was conducted using PubMed, MEDLINE, and Google Scholar. Studies on the relationship between IBD or bariatric surgery and the risk of kidney stone formation were included. RESULTS Dietary composition has a critical role in urinary stone formation. Nutritional factors such as fluid intake, dietary protein, carbohydrates, oxalate, and calcium contribute to the risk of stone formation. Bowel-related malabsorptive conditions (IBD, after bariatric surgery, etc.) are associated with an increased risk of kidney stone formation due to metabolic and physiological changes such as hyperoxaluria, hypocitraturia, and decreased fluid intake or absorption. While the risk is lower in restrictive bariatric surgeries, the risk of kidney stone formation increases, especially after malabsorptive procedures. Dietary recommendations for these patients could profit alleviate urinary changes and reduce the risk of kidney stones. CONCLUSION Bowel-related malabsorptive conditions such as IBD and bariatric surgery are associated with an increased risk of kidney stones. Appropriate dietary recommendations can improve urinary metabolic changes and reduce kidney stone formation and the possibility of stone-related surgery.

Nutrients 2022; 14:nu14234964. [PMID: 36500994 PMCID: PMC9738379 DOI: 10.3390/nu14234964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/18/2022] [Accepted: 11/20/2022] [Indexed: 11/24/2022] Open
Abstract
The environment has rapidly looked at proven specialist task forces in the aftermath of the COVID-19 pandemic to build public health policies and measures to mitigate the effects of emerging coronaviruses. According to the researchers, taking 10 μg of 25-hydroxy vitamin D daily is recommended to keep us safe. There have been several studies recently indicating that there is a reduced risk of contracting Coronavirus by 25-hydroxy vitamin D consumption, even though there is no scientific data to prove that one would not affect the COVID-19 viral infection by 25-hydroxy vitamin D consumption. In this regard, the present study investigates the important literature and the role of 25-hydroxy vitamin D to prevent COVID-19 infection by conducting an in-silico study with SARS-CoV-2 spike protein as a target. Lopinavir, a previously reported drug candidate, served as a reference standard for the study. MD simulations were carried out to improve predictions of receptor-ligand complexes which offer novelty and strength to the current study. MD simulation protocols were explored and subjected to 25-hydroxy vitamin D and a known drug, Lopinavir. Comparison of ligands at refined models to the crystal structure led to promising results. Appropriate timescale simulations have been used to understand the activation mechanism, the role of water networks for receptor function, and the ligand binding process. Furthermore, MD simulations in combination with free energy calculations have also been carried out for lead optimization, evaluation of ligand binding modes, and assessment of ligand selectivity. From the results, 25-hydroxy vitamin D was discovered to have the vital interaction and highest potency in LBE, lower RMSD, and lower inhibition intensity similar to the standard. The findings from the current study suggested that 25-hydroxy vitamin D would be more effective in treating COVID-19. Compared with Lopinavir, 25-hydroxy vitamin D had the most potent interaction with the putative binding sites of the SARS-CoV-2 spike protein of COVID-19.

Abstract
BACKGROUND Hypocalcaemia is a common complication after thyroidectomy. Bariatric surgery is associated with significant changes in calcium metabolism. Some studies have identified bariatric surgery as a risk factor for hypocalcaemia after thyroidectomy. This systematic review and meta-analysis assessed whether a history of bariatric surgery was associated with an increased risk of hypocalcaemia after thyroidectomy. METHODS This prospectively registered systematic review (PROSPERO; CRD42021295423) was performed in accordance with PRISMA guidelines. Meta-analysis was undertaken using the Mantel-Haenszel method, with outcomes reported as ORs with 95 per cent confidence intervals. RESULTS Twenty studies were included in the qualitative synthesis. Five studies incorporating 19 547 patients met the inclusion criteria for meta-analysis, of whom 196 (1.0 per cent) had a history of bariatric surgery. Patients with a history of bariatric surgery were more likely to develop hypocalcaemia after thyroidectomy (30.6 versus 13.0 per cent; OR 3.90, 95 per cent c.i. 1.50 to 10.12; P = 0.005). Among those with a history of bariatric surgery, patients who underwent a bypass procedure were more likely to develop hypocalcaemia after thyroidectomy than those who had a restrictive procedure (38 versus 23 per cent; OR 2.12, 1.14 to 3.97; P = 0.020). CONCLUSION Patients with a history of bariatric surgery have a significantly greater risk of hypocalcaemia after thyroidectomy, with a heightened risk among those who have had a bypass procedure. Surgeons performing thyroid surgery should be aware of the increased risk of hypocalcaemia after thyroidectomy among these patients.

Abstract
Background: Studies have suggested that patients with prior gastric bypass may be at increased risk for hypocalcemia following thyroidectomy. Unfortunately, most of these studies are limited to case reports and small series. This study represents the largest sample size to date to assess the incidence of post-thyroidectomy hypocalcemia in patients with a history of bariatric surgery. Methods: The TriNetX Research Network was queried to retrospectively identify patients with prior bariatric surgery who underwent total thyroidectomy between 2011 and 2021. The incidence of hypocalcemia following surgery was compared with patients who underwent total thyroidectomy, and hemithyroidectomy with no history of bariatric surgery. Results: We identified 446 patients with a history of bariatric surgery and subsequent thyroidectomy, 29,346 patients with total thyroidectomy, and 19,603 patients with hemithyroidectomy alone. The one-month incidence of hypocalcemia was 54.7% in those with a history of bariatric surgery who underwent thyroidectomy, 43.9% in those with thyroidectomy alone (relative risk, RR = 1.2 [confidence interval, CI 1.1-1.4], p < 0.001), and 8.1% in those with hemithyroidectomy only (RR = 6.8 [CI 6.1-7.4], p < 0.001). Permanent hypocalcemia was documented in 11.4% of patients with prior bariatric surgery who underwent thyroidectomy, 7.7% of those with thyroidectomy only (RR = 1.5 [CI 1.1-1.9], p = 0.003), and 2.9% of patients with hemithyroidectomy alone (RR = 3.9 [CI 3.0-5.2], p < 0.001). Significant differences persisted after matching demographics, prior need for supplementation, and risk factors for hypocalcemia after thyroidectomy. When stratified by bariatric procedure, patients with a history of Roux-en-Y gastric bypass (RYGB) (n = 35) had a greater, although not statistically significant, risk of short-term hypocalcemia (51.4%; RR = 1.2 [CI 0.8-1.6], p = 0.37), and a significantly increased risk of permanent hypocalcemia (20.0%; RR = 2.6 [CI 1.3-5.1], p = 0.005) compared with thyroidectomy alone. Sleeve gastrectomy (SG) (n = 40) was not associated with an increased risk of short-term (40.0%; RR = 0.9 [CI 0.6-1.3], p = 0.62) or permanent (7.5%; RR = 1.0 [CI 0.3-2.9], p = 0.96) hypocalcemia. Conclusions: Prior RYGB, but not SG, may increase the risk of permanent hypocalcemia after thyroidectomy. Additional research is necessary to determine optimal prevention and treatment strategies to reduce morbidity in this population.

Abstract
BACKGROUND The number of bariatric surgeries performed worldwide is growing. Among the main short, medium or long-term complications after surgery are nutritional deficiencies. Many of these, such as those of Zn, Cu and vitamins A, B1, B3, B6 and B12, are manifested by dermatological lesions before potentially fatal systemic disorders occur. OBJECTIVE To identify the main dermatological manifestations associated with nutritional deficiencies after bariatric surgery, and the associated variables. DESIGN AND SETTING Integrative literature review carried out at a public university in Brazil. METHODS This was a case report and a review of health research portals and databases of national and international biomedical journals, without publication date limitation. The descriptors used for searches followed the ideal methodology for each database/search portal: "bariatric surgery", "skin", "skin disease", "skin manifestation", "deficiency disease" and "malnutrition". RESULTS A total of 59 articles were selected, among which 23 were review articles or articles that addressed specific dermatological manifestations. The other 36 articles described 41 cases, which were organized into a table with the clinical variables. CONCLUSIONS Although nutritional deficiencies are expected as complications after bariatric surgery, few articles relating them to their dermatological manifestations were found. It is important to recognize skin changes caused by nutritional deficiencies in patients treated via bariatric surgery, as these may occur before systemic complications appear and are easier to diagnose when the patient does not have any systemic symptoms yet. However, there is generally a delay between the appearance of skin lesions and making the diagnosis of nutritional deficiency.

Safety of biliopancreatic diversion with duodenal switch in patients with body mass index less than 50 kg/m 2. Surg Endosc 2022; 37:3046-3052. [PMID: 35922604 DOI: 10.1007/s00464-022-09483-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Accepted: 07/13/2022] [Indexed: 10/16/2022]
Abstract
INTRODUCTION Biliopancreatic diversion with duodenal switch (BPD-DS) has often been reserved for patients with BMI > 50 kg/m2. We aim to assess the safety of BPD-DS in patients with morbid obesity (BMI 335 kg/m2 and < 50 kg/m2) using a 150-cm common channel (CC), 150-cm Roux limb, and 60-fr bougie. METHODS A retrospective review was performed on patients with a BMI < 50 mg/k2 who underwent a BPD-DS in 2016-2019 at a single institution. Limb lengths were measured with a laparoscopic instrument with minimal tension. Sleeve gastrectomy was created with 60-fr bougie. Variables were compared using paired t test, Chi-square analysis or repeated measures ANOVA where appropriate. RESULTS Forty-five patients underwent BPD-DS. CC lengths and Roux limb lengths were 158 ± 20 cm and 154 ± 18 cm, respectively. Preoperative BMI was 44.9 ± 2.3 kg/m2 and follow-up was 2.7 ± 1.4 years. One patient required reoperation for bleeding and died from multiorgan failure and delayed sleeve leak. There was 1 (2.2%) readmission for contained anastomotic leak and 2 ED visits (4.5%) within 30 days. There were no marginal ulcers, limb length revisions, or need for parental nutrition. Percent excess weight loss was 67.2 ± 19.7%. 88.9% (N = 8), 86.6% (N = 13), and 55.5% (N = 5) of patients had resolution or improvement of their diabetes mellitus type II, hypertension, and hyperlipidemia, respectively. 40% (N = 4) of patients had resolution of their gastroesophageal reflux disease (GERD) and 11.4% (N = 5) developed de novo GERD. 32% (N = 14) of patients had vitamin D deficiency and 25% (N = 11) experienced zinc deficiency. CONCLUSION BPD-DS may be considered in patients with BMI < 50 kg/m2 with 150-cm CC, 150-cm Roux limb, and a 60-fr bougie sleeve gastrectomy. There was sustained weight loss and no protein calorie malnutrition, but Vitamin D and zinc deficiency remained a challenge. Careful patient selection and proper counseling of the risks and benefits are necessary.

Abstract
Due to the increased prevalence of obesity in the last decades, bariatric surgery has been on the rise in recent years. Bariatric surgery is a compelling option for weight loss in obese patients with severe obesity-related comorbidities or for whom lifestyle modifications have proven ineffective. Redundant skin following significant weight loss is a common occurrence affecting up to 96% of patients who undergo bariatric surgery, negatively impacting physical and psychosocial health and detracting from activities of daily living. Statistics of the American Society of Plastic Surgeons show that 46,577 body contouring procedures were performed after massive weight loss in the USA in a 2020 report. Abdominoplasty, a well-established cosmetic surgery procedure for improving body contour, is performed by removing excess skin and fat from the abdominal wall and thereby restoring musculofascial integrity and skin elasticity, resulting in a more ideal body shape and increasing quality of life. Although abdominoplasty is a safe procedure, it has been associated with a higher complication rate compared with other body-contouring procedures. Technologic advances over the past decade have been developed as non-invasive alternatives or adjunctive tools to surgery to enhance cosmetic results and minimize complications. New energy-based technologies may supplant invasive surgery for mild to moderate skin laxity and/or diminish the extent of surgery and resulting scars. Plastic surgeons play a significant role in improving the quality of life of patients who suffer from obesity and underwent bariatric surgery. We are deeply convinced, however, that the advancement of knowledge and research in this field will determine the introduction of new technologies and custom-made techniques. This advancement will reduce the complication rate with a rapid reintegration of the patient into the world of work and resumption of daily activities.

Abstract
The incidence of bariatric surgery is increasing due to obesity being one of our top public health challenges. As such, bariatric-related ophthalmic changes are a potentially new clinical area of knowledge, with increasing published evidence on post-bariatric complications experienced by patients and identified by clinicians. We reviewed the available literature and summarised the different complications and potential recommendations. A search strategy was conducted with PubMed, Cochrane, Medline, Embase, Allied and Complementary Medicine and DH-DATA databases to look for papers answering our research question: "What are the ophthalmological complications for patients after bariatric surgery?". Our search gave a total of 59 relevant papers. Bariatric surgery, particularly subtypes that cause direct bypass of nutrients from the stomach, lead to nutritional deficiencies. Vitamin A, crucial for proper functioning of body systems and specialised cells, manifests ophthalmologically as corneal ulceration, nyctalopia, conjunctival xerosis and more. Thiamine levels are also depleted, leading to Wernicke's Encephalopathy. Pre-existing diabetic retinopathy is also noted to worsen sub acutely, although evidence is conflicting. Patients undergoing surgery to treat idiopathic intracranial hypertension would have reduced IOP and resolving papilloedema. Other comorbidities of obesity like HBA1C levels, obstructive sleep apnoea, and metabolic syndrome also resolve post-surgery. History taking remains the cornerstone of medical practice. From the evidence, we suggest consideration of pre-surgery screening for ophthalmic pathology and post-operative monitoring of disease progression. Real-world data needs to continuously be analysed to create definitive management pathways that can help clinicians recognise ophthalmic complications early, improving patient outcomes.

Abstract
INTRODUCTION Bariatric surgery (BS) is known to reduce several obesity-related complications during pregnancy, but there is concern that it may increase the risk of maternal-fetal morbidity because of the malabsorption. This study aimed to investigate the impact of restrictive BS on several pregnancy outcomes in comparison with different grades of obesity. MATERIALS AND METHODS A single-center retrospective case-control study. All primiparous singleton pregnant women who underwent BS between the previous 1-5 years or with body mass index (BMI) ≥ 30 kg/m2 delivering in our center were included. Obstetric and perinatal outcomes were analyzed and compared between the two groups. RESULTS Overall, 90 women were included: 30 underwent BS and 60 were obese. The mean pre-pregnancy BMI was 31.0 ± 4.2 kg/m2 in the BS group and 38.1 ± 4.3 kg/m2 in the control group (p < 0.001). The obese group experienced higher rate of fetal macrosomia (25% vs 6.7%; p = 0.049), gestational hypertension (23.3% vs 3.3%; p = 0.04), preeclampsia (23.3% vs 0%; p = 0.04), gestational diabetes (33.3% vs 6.7%; p = 0.01), and cesarean section (68.3% vs 20%; p < 0.0001). The BS group showed higher frequency of small for gestational age (SGA) (46.7% vs 18.3%; p = 0.006), late preterm delivery (PTD) (33.3% vs 10%; p = 0.009), cholestasis (13.3% vs 1.7%; p = 0.049). Breastfeeding ≥ 6 months was higher among BS mothers (36.7% vs 11.7%; p = 0.007). CONCLUSIONS Our findings support the positive impact of BS on several obstetric outcomes, at the expense of a higher frequency of SGA and PTD. BS mothers more frequently achieved the recommended goal of breastfeeding for 6 months compared to obese women.

Abstract
INTRODUCTION The duodenal switch is the most effective bariatric surgical procedure. Due to technical demands of the surgery and concerns regarding high rates of post-operative nutritional sequelae, many surgeons remain hesitant to adopt this technique. METHODS Sixty-five patients undergoing duodenal switch surgery at our hospital between 2008 and 2015 were followed up for 5 years. All patients were provided with a thorough post-operative nutritional supplementation regimen. Nutritional deficiencies as evidenced by blood testing, excess body weight loss, and remission rates from type 2 diabetes, hypertension, and dyslipidaemia were studied. RESULTS The average excess body weight loss 5 years post-operatively was 62% ± 23.03%. Remission rates for type 2 diabetes, hypertension, and dyslipidaemia were 96%, 77% and 84% respectively. Patients achieved good nutritional outcomes. After 5 years, deficiencies in fat-soluble vitamins A and D occurred in 3.3% and 1.6% of patients respectively. The rate of ferritin deficiency at the 5-year post-operative mark was 19.4%. No predictors of nutritional deficiency were identified on univariate analysis. CONCLUSION Patients undergoing a duodenal switch achieve good long-term excess body weight loss and high obesity-related co-morbidity remission rates. The rates of post-operative nutritional deficiencies in patients who are subjected to a thorough post-operative nutritional supplementation regimen are lower than what was historically expected.

Abstract
Background: Vitamin D insufficiency is common before and after bariatric surgery. Optimal supplementation to treat vitamin D insufficiency is not clearly defined. Objective: Determine if serum 25 (OH) D levels improve by the consumption of an additional monthly ergocalciferol supplement by subjects after bariatric surgery. Study design: Thirty-two subjects were randomly divided to receive an additional 100,000 IUs of ergocalciferol monthly after bariatric surgery (n=10) or standard level vitamin D supplement after bariatric surgery (n=22). Serum 25 (OH) D, calcium, and hemoglobin A1c levels were measured preoperatively and one year after bariatric surgery. Results: Mean changes in BMI at 1-year post-operation was -18.12±6.46 kg/m2 in the control group versus -18.84±4.7 kg/m2; p=0.638 in the vitamin D group. One year after bariatric surgery, the mean changes from baseline in vitamin D levels were 2.69±9.4 and 12.4±17.0 ng/mL in control and intervention groups, respectively. The treated group showed a marginally higher mean increase in Vitamin D than the control group, p=0.059. Other mean changes at 1-year post-surgery that were not significantly different include calcium -0.264±0.45 and -0.21±0.509 mg/dl in control and intervention groups, respectively and Hgb A1c -1.0±1.21 and -0.95±0.071% in control and intervention groups, respectively. Conclusion: This study showed 100,000 IUs ergocalciferol once a month is a safe and effective treatment for vitamin D insufficiency in most patients having bariatric surgery.

Abstract
A 55-year-old Caucasian woman presented with a 1-week history of left eye redness and blurred vision. Her medical history included previous small bowel resection and ileostomy for ischaemic bowel. Ophthalmic examination revealed a left corneal ulcer requiring hospital admission for intensive topical antibiotics. Overnight she became systemically unwell and was diagnosed with urinary tract infection requiring intravenous antibiotics. Her corneal condition deteriorated resulting in corneal perforation, which required a surgical gluing procedure. Despite surgery, the cornea perforated on two further occasions. At this stage, vitamin A deficiency (VAD) was suspected, due to the corneal melting response that was occurring. VAD was subsequently confirmed by serology and had occurred in this case due to malabsorption as a result of short bowel syndrome caused by previous small bowel surgery. The patient was treated with intramuscular vitamin A and eventually made a good visual and systemic recovery.

Abstract
Background Hypocalcemia is a common complication after total thyroidectomy (TT). A history of bariatric surgery has been identified as a risk factor for this complication. This study aimed to assess the risk of hypocalcemia post TT in patients with a history of obesity procedures: laparoscopic sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (RYGB), and laparoscopic gastric banding (LAGB). Methods We compared the risk of hypocalcemia post TT (serum calcium levels <8 mg/dL) between patients with restrictive (LSG and LAGB), malabsorptive (RYGB), and patients without a history of obesity surgery. Hypoparathyroidism was considered permanent if the plasma parathyroid hormone (PTH) levels at 6 months were less than 15 pg/mL (normal range: 15-65 pg/mL) and the patient still required oral calcium (calcium carbonate) and vitamin D supplementation, in addition to the supplements that were taken routinely before thyroidectomy. Results From the 13,242 patients who underwent TT from 2006 to 2018, 90 patients (0.7%) had a history of bariatric surgery: 35 LAGB, 29 LSG, and 26 RYGB. The risk of hypocalcemia was higher in RYGB patients (50%, n=13) than in LAGB (17.1%, n=6) or LSG patients (20.6%, n=6) (P=0.003). Furthermore, hypocalcemia risk was similar between patients with a history of restrictive procedures (18.8%, 12/64) and patients with no history of bariatric surgery (17.2%, 2,268/13,152) (P=0.4). Permanent hypoparathyroidism was observed in one and 6 patients from the LAGB and RYGB groups, respectively; however, it was not observed in any patient from the LSG group. Conclusions RYGB is a risk factor for hypocalcemia post TT, while restrictive bariatric procedures are not.

A case series and systematic review. ANNALES D'ENDOCRINOLOGIE 2021; 82:572-581.

Abstract
BACKGROUND Postoperative hypoparathyroidism (PH) is the most common complication after total thyroidectomy. Incidence varies from 2% to 83%, depending on the definition. OBJECTIVE We performed a systematic review of the literature to determine the medico-economic effects of PH and update understanding of long-term consequences, morbidity, and quality of life related to hypoparathyroidism. METHODS We considered relevant articles published between 2000 and 2020 concerning long-term consequences of PH and quality of life. All studies concerning the medico-economic assessment of PH were included. We compared data from 2018 to results in the literature. RESULTS A proportion of 64/403 (16.8%) patients presented with transient PH during 2018, and 7/403 (1.7%) had permanent PH. Seven patients needed supplementation with alfacalcidol at 6-month follow-up. Factors predicting the need for alfacalcidol were age <45, thyroidectomy for goiter, and lymph node dissection. Additional therapy costs related to PH were €9781.10, and additional hospital costs were €230,400. We qualitatively synthesized 41 studies. Most were retrospective studies and only a few reported costs. No series assessed direct or indirect costs of postoperative PH. CONCLUSION To our knowledge, no previous studies reported the medico-economic impact of PH. Decreasing PH associated with fluorescence usage should be considered, particularly concerning cost-effectiveness.

Abstract
Bariatric surgery (BS) has proven to be highly efficacious in the treatment of obesity and its comorbidities. However, careful patient selection is critical for its success. Thus, patients should undergo medical, behavioral, and nutritional assessment by a multidisciplinary team. From the nutritional point of view, BS candidates should undergo nutritional assessment, preparation, and education by a registered dietitian in the preoperative period. Currently, detailed specified and comprehensive information on these topics is lacking. The present narrative review aimed to summarize the available literature concerning both the preoperative nutritional assessment components and the preoperative nutritional preparation and education components of patients planning to undergo BS. Current literature indicates that proper management before BS should include a comprehensive nutritional assessment, in which it is advisable to perform a clinical interview to assess patients' medical background, weight management history, eating patterns and pathologies, oral health, physical activity habits, nutritional status, supplementation usage, BS knowledge, surgery expectations and anthropometric measurements. Nutritional preparation and educational strategies should include an individualized preoperative weight-loss nutrition program, improvement of glycemic control, micronutrients deficiencies correction, eating and lifestyle habits adaptation, physical activity initiation, and strengthening knowledge on obesity and BS. At this stage, more well-designed intervention and long-term cohort studies are needed in order to formulate uniform evidence-based nutritional guidelines for patients who plan to undergo BS, including populations at higher nutritional risk. Moreover, postoperative outcomes of presurgical nutritional intervention programs should be studied.

Abstract
Body contouring surgery after the massive weight loss due to bariatric surgery deals with different kinds of complications. The aim of this review is to analyze the role that some nutrients may play in tissue healing after surgery, thus helping plastic surgeons to improve the aesthetic and health outcomes in massive weight loss patients under a multidisciplinary approach. As a matter of fact, preoperative nutritional deficiencies have been shown for vitamins and minerals in a large percentage of post-bariatric patients. Preoperative deficiencies mainly concern iron, zinc, selenium, and vitamins (both fat-soluble and water-soluble), but also total protein. During the postoperative period, these problems may increase because of the patients' very low intake of vitamins and minerals after bariatric surgery (below 50% of the recommended dietary allowance) and the patients' low compliance with the suggested multivitamin supplementation (approximately 60%). In the postoperative period, more attention should be given to nutritional aspects in regard to the length of absorptive area and the percentage of weight loss.

Abstract
PURPOSE To assess serum vitamin D trend from baseline to 12 months after one anastomosis gastric bypass (OAGB). MATERIALS AND METHODS In this observational cohort analysis of longitudinal data, we assessed the trend of serum vitamin D, and its associations with anthropometric, and biochemical measurements in 98 patients undergoing OAGB in a bariatric surgery center. All participants were on >800 IU/day vitamin D supplementation. RESULTS Vitamin D, lipid profile, creatinine, and albumin levels significantly improved at 12 months post-surgery. Vitamin D concentrations significantly increased from 26.52 ± 12.32 to 54.52 ± 27.90 ng/mL at 12 months. The correlations between vitamin D concentrations and weight, body mass index, lipid profile, ferritin, glycemic indices, and albumin were not significant. In addition, the correlations between vitamin D and parathormone, vitamin D receptor, calcium, phosphorus, body composition, and basal metabolic rate (BMR) did not reach the threshold of statistical significance at 12 months following bariatric surgery. Although there was a significant correlation between body weight and body composition (P < 0.001) and basal metabolic rate (BMR) (r = 0.762, P < 0.001) at 12 months, there were no significant correlations between weight change percent and body composition (P > 0.05), BMR (r = -0.101, P = 0.350), and vitamin D (r = 0.120, P = 0.271) at 12 months. CONCLUSION Our results showed that supplementation of vitamin D with dosage of >800 IU/day is sufficient for prevention of vitamin D deficiency within 12 months after OAGB surgery. Note: This data is mandatory.

Abstract
BACKGROUND In women, bariatric surgery (BS) leads to a decline in bone mineral density (BMD) and may ultimately lead to premature osteoporosis. The impact in men is largely unknown. OBJECTIVE To assess the effect of BS on bone metabolism in males. SETTING Single-center prospective cohort study. METHODS Twenty-four male BS candidates were prospectively enrolled. Anthropometric characteristics, serum gonadal hormones, markers of bone metabolism, and BMD were measured at baseline, 6-, 12- and 36-months postoperatively. RESULTS Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (AGB) were performed in 15 and 9 patients, respectively. Nineteen patients completed the 3-year follow-up. At 3 years, BMD of the right and left femur had decreased by 9.1 ± 7.2% and 9.4 ± 5.8% for RYGB and by 6.7 ± 3.9% and 4.5 ± 2.8% for AGB. Radius BMD had decreased by 14.0 ± 5.6% for RYGB and 5.9 ± 4.1% for AGB, i.e., significantly stronger for RYGB (P = .006). Serum parathyroid hormone increased in both groups and 13 of 19 patients developed Vitamin D deficiency. A significant increase of the bone resorption marker was seen only during the first year despite continuation of bone loss. Four patients developed de novo osteopenia or osteoporosis. No fractures were observed. CONCLUSION There are strong indications that male bone metabolism response after BS differs from female metabolism. The most affected site is the radius. In males, the cause of this BMD loss seems multifactorial, including mechanical unloading, hyperparathyroidism, and hypogonadism. However, clinical relevance remains unknown and therefore studies with longer-term follow-up are necessary.

Vitamin E status among bariatric surgery patients: a systematic review. Surg Obes Relat Dis 2020; 17:816-830.

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

Abstract
Bariatric surgery is recognized as the most clinically and cost-effective treatment for people with severe and complex obesity. Many people presenting for surgery have pre-existing low vitamin and mineral concentrations. The incidence of these may increase after bariatric surgery as all procedures potentially cause clinically significant micronutrient deficiencies. Therefore, preparation for surgery and long-term nutritional monitoring and follow-up are essential components of bariatric surgical care. These guidelines update the 2014 British Obesity and Metabolic Surgery Society nutritional guidelines. Since the 2014 guidelines, the working group has been expanded to include healthcare professionals working in specialist and non-specialist care as well as patient representatives. In addition, in these updated guidelines, the current evidence has been systematically reviewed for adults and adolescents undergoing the following procedures: adjustable gastric band, sleeve gastrectomy, Roux-en-Y gastric bypass and biliopancreatic diversion/duodenal switch. Using methods based on Scottish Intercollegiate Guidelines Network methodology, the levels of evidence and recommendations have been graded. These guidelines are comprehensive, encompassing preoperative and postoperative biochemical monitoring, vitamin and mineral supplementation and correction of nutrition deficiencies before, and following bariatric surgery, and make recommendations for safe clinical practice in the U.K. setting.

Abstract
Some forms of bariatric surgery make patients susceptible to calcium malabsorption, and the parathyroid hormone (PTH) axis is important for maintaining normocalcemia in these patients. Injury to the parathyroid glands due to anterior neck surgery commonly causes PTH axis disruption and can result in severe hypocalcemia in bariatric surgery patients. Herein, we present a case of a patient with a history of stomach intestinal pylorus-sparing bariatric surgery who developed refractory hypocalcemia requiring daily intravenous (IV) calcium 2 years after thyroidectomy. PTH levels were inappropriately normal during episodes of hypocalcemia, and urinary calcium level was <3.0 mg/dL following large oral doses of calcium, suggesting that both inadequate PTH response and malabsorption contributed to her severe hypocalcemia. In order to enhance calcium absorptive capacity while minimizing the risk of weight regain, she was surgically treated with a Roux-en-Y gastric bypass proximal to the prior operation. The surgery successfully improved blood calcium levels; the patient was successfully weaned from IV calcium and was able to maintain normocalcemia with oral supplements. We discuss the case in the context of available literature and provide our recommendations.

Abstract
BACKGROUND Bariatric surgery is by far the most effective treatment option available for successfully achieving and maintaining weight loss in the obese population, but it can also be associated with complications that lead to malnutrition. There is limited data on how enteral nutrition (EN) can be used to provide nutrition support in such cases. METHODS Retrospective review of our Home Enteral Nutrition (HEN) database was conducted from February 2013 to April 2018 to identify patients who received HEN because of bariatric surgery-related complication. RESULTS During the study period, 72 patients (86% female, mean age 50.3 ± 11.6 years) initiated HEN because of bariatric surgical complication. Most common bariatric surgery was Roux-en-Y (74%) and most common indication for HEN was malnutrition/failure to thrive (33%). HEN was most commonly provided through nasojejunal feeds and resulted in an average increase in body weight and body mass index from 74.8 kg and 26.5, respectively, before HEN to 76.9 kg and 27.2, respectively, at the end of the HEN period. Through HEN, patients received 22.2 ± 7.9 kcal/kg/d and 1.0 ± 0.3 g/kg/d protein, meeting 94% ± 17% of their energy goals and 95% ± 29% of their protein goals. Vitamin deficiencies were noted in 69% of patients at the time of HEN initiation, which improved to 10% after enteral feeds and appropriate vitamin supplementation. CONCLUSION HEN is safe and effective in treating malnutrition and vitamin deficiencies that might occur as a complication of bariatric surgery, leading to avoidance of parenteral nutrition support in most cases.

Abstract
INTRODUCTION After bariatric surgery (BS), patients might suffer from nutrient maldigestion, malabsorption, and vitamin deficiencies. In this study, our aim was to assess pancreatic functions after BS using fecal elastase-1 assay (FE-1). MATERIAL AND METHODS Sixty patients (21M) undergoing BS and 20 (6M) healthy controls were included into the study. Stool samples were collected 1 year after surgery. Ten patients from one anastomosis gastric bypass (OAGB) and single anastomosis duodenal switch (SADS) groups with the lowest value of FE-1 and GIQLI scores were given pancreatic enzyme replacement therapy (PERT). After PERT, FE-1, excess weight loss (EWL), BMI, GIQLI scores, and vitamin D levels were measured. RESULTS Vitamin D levels were detected as 19.04 (9-46.5) pg/ml, 15.1 (8.4-23.6) pg/ml, 17.8 (5-30) pg/ml, and 21.79 (11-40.3) pg/ml after sleeve gastrectomy (SG), OAGB, SADS, and control groups, respectively (p = 0.04). GIQLI scores in the first year were found to have increased in all patients (p = 0.02). FE-1 levels were found as 642.35 (566.3-711.4) μg/g, 378.52 (183.5-561.1) μg/g, 458.88 (252.5-593, 5) μg/g, and 518.2 (351.6-691) μg/g for the SG, OAGB, SADS, and control groups, respectively. There was a strong inverse correlation between EWL and FE-1 levels at the end of the first year (Spearman's rho = - 0.688, p = 0.003). After having performed PERT for patients with the lowest FE-1 levels, the levels increased to 683.39 (615.5-720) μg/g in the OAGB and 691.5 (643.1-720) μg/g in the SADS groups (p = 0.011). CONCLUSION FE-1 measurements demonstrated that many patients suffer from malabsorption after OAGB or SADS, whereas functions remain normal after SG. PERT corrects pancreatic functions without affecting weight loss and also contributes to the normal serum level of vitamin D.

Iron, Vitamin B 12, Folate and Copper Deficiency After Bariatric Surgery and the Impact on Anaemia: a Systematic Review. Obes Surg 2020; 30:4542-4591. [PMID: 32785814 DOI: 10.1007/s11695-020-04872-y] [Citation(s) in RCA: 37] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Revised: 07/19/2020] [Accepted: 07/22/2020] [Indexed: 12/20/2022]
Abstract
Bariatric surgery may increase the risk of iron, vitamin B12, folate and copper deficiencies, which can cause anaemia. This review aims to critique the evidence on the prevalence of these nutritional deficiencies and the impact on anaemia in the first 12 months after surgery. PRISMA and MOOSE frameworks, the NHMRC evidence hierarchy and The Academy of Nutrition and Dietetics bias tool were used to systematically critique current literature. Seventeen studies reported on deficiency prevalence with the majority being of low quality. Important confounders to serum micronutrient levels were not adequately considered. Results on the prevalence of nutritional anaemias were also lacking. Further investigation into the prevalence of iron, vitamin B12, folate and copper deficiency and its impact on anaemia in bariatric surgery is needed.

Abstract
Bariatric surgery (BS) is one of the most common and efficient surgical procedures for sustained weight loss but is associated with long-term complications such as nutritional deficiencies, biliary lithiasis, disturbances in bone and mineral metabolism and an increased risk of nephrolithiasis, attributed to urinary metabolic changes resultant from low urinary volume, hypocitraturia and hyperoxaluria. The underlying mechanisms responsible for hyperoxaluria, the most common among all metabolic disturbances, may comprise increased intestinal oxalate absorption consequent to decreased calcium intake or increased dietary oxalate, changes in the gut microbiota, fat malabsorption and altered intestinal oxalate transport. In the current review, the authors present a mechanistic overview of changes found after BS and propose dietary recommendations to prevent the risk of urinary stone formation, focusing on the role of dietary oxalate, calcium, citrate, potassium, protein, fat, sodium, probiotics, vitamins D, C, B6 and the consumption of fluids.

Abstract
BACKGROUND Whether one anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) is a better revisional bariatric surgery (RBS) after sleeve gastrectomy (SG) is still under debate. The aim is to compare short-term outcomes of RYGB and OAGB as a RBS after SG, pertaining to their effects on weight loss, resolution of comorbidities, and complications. METHODS We performed a single-center analysis of 55 patients (n = 34 OAGB, n = 21 RYGB). Indications for revisional surgery included weight regain/loss failure (67%) and intractable gastroesophageal reflux disease (33%). Data were collected up to 1-year follow-up (FU) and included time of revisional surgery, operation time, weight, body mass index, excess weight loss, and total weight loss (TWL), both in percent, complications and resolution of comorbidities. RESULTS Operation time was 79 ± 36 (OAGB-MGB) and 98 ± 24 min (RYGB) (p = 0.03). In the first 30 postoperative days, three patients in the RYGB group, and no patient in the OAGB group, had postoperative complications. FU was 100%. Minor complication rates at 12 months were 33.3% (RYGB) and 35.3% (OAGB). At 12 months, mean % TWL was 10.3 ± 7.6% (RYGB) and 15.8 ± 7.8% (OAGB) (p = 0.0132). CONCLUSIONS OAGB after failed SG was found to be a quicker procedure with less perioperative complications. At 1-year FU, no significant differences were seen between RYGB and OAGB regarding readmission and minor complications. Still long-term FU including the risk of malnutrition is needed to have a complete evaluation of OAGB as a RBS for the future.

Increases in PYY and uncoupling of bone turnover are associated with loss of bone mass after gastric bypass surgery. Bone 2020; 131:115115. [PMID: 31689523 PMCID: PMC6930344 DOI: 10.1016/j.bone.2019.115115] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 10/07/2019] [Accepted: 10/17/2019] [Indexed: 02/08/2023]
Abstract
CONTEXT The gut hormones peptide YY (PYY) and ghrelin mediate in part the metabolic benefits of Roux-en-Y gastric bypass (RYGB) surgery. However, preclinical data suggest these hormones also affect the skeleton and could contribute to postoperative bone loss. OBJECTIVE We investigated whether changes in fasting serum total PYY and ghrelin were associated with bone turnover marker levels and loss of bone mineral density (BMD) after RYGB. DESIGN, SETTING, PARTICIPANTS Prospective cohort of adults undergoing RYGB (n=44) at San Francisco academic hospitals. MAIN OUTCOME MEASURES We analyzed 6-month changes in PYY, ghrelin, bone turnover markers, and BMD by dual-energy x-ray absorptiometry (DXA) and quantitative computed tomography (QCT). We calculated the uncoupling index (UI), reflecting the relative balance of bone resorption and formation. RESULTS Postoperatively, there was a trend for an increase in PYY (+25pg/mL, p=0.07) and a significant increase in ghrelin (+192pg/mL, p<0.01). PYY changes negatively correlated with changes in spine BMD by QCT (r=-0.36, p=0.02) and bone formation marker P1NP (r=-0.30, p=0.05). Relationships were significant after adjustments for age, sex, and weight loss. No consistent relationships were found between ghrelin and skeletal outcomes. Mean 6-month UI was -3.3; UI correlated with spine BMD loss by QCT (r=0.40, p=0.01). CONCLUSIONS Postoperative PYY increases were associated with attenuated increases in P1NP and greater declines in spine BMD by QCT. Uncoupling of bone turnover correlated with BMD loss. These findings suggest a role for PYY in loss of bone mass after RYGB and highlight the relationship between intestinal and skeletal metabolism.

Abstract
BACKGROUND/AIM Both bariatric and thyroid surgeries promote calcium and vitamin D deficiency. The correlation, however, of hypocalcemia after thyroidectomy in patients with previous bariatric surgery has been poorly described. This review aimed to investigate the relationship between history of bariatric operations and post-thyroidectomy hypocalcemia, as well as suggested management options. MATERIALS AND METHODS MEDLINE and Cochrane databases were searched for relevant publications regarding post-thyroidectomy hypocalcemia in patients with previous bariatric surgery. RESULTS A total of 17 publications reporting on 126 patients met the inclusion criteria. These included 13 publications about Roux-en-Y gastric bypass (RYGB), 2 regarding biliopancreatic diversion (BPD), 1 about sleeve gastrectomy (SG) and 1 compared three bariatric procedures: SG, RYGB, laparoscopic adjustable gastric band (LAGB). Post-thyroidectomy hypocalcemia was found to be more prevalent in patients with previous RYGB and BPD, but not in previous LAGB and SG. CONCLUSION Patients with previous bariatric surgery are at high risk of post-thyroidectomy hypocalcemia that sometimes leads to higher length of hospital stay and demands more invasive solutions. There is a need, however, for additional studies and further investigation in order to reach more conclusive results.

Abstract
Biliopancreatic diversion is a surgical procedure that causes weight loss via volume restriction and malabsorption. It is now rarely performed due to the risk of severe nutritional deficiencies including vitamin A. We report a case of severe vitamin A deficiency due to malabsorption from a biliopancreatic diversion procedure for weight loss. By the time the patient presented to our department, she had developed blindness refractory to parenteral vitamin A treatment. A unique feature of her case is the development of a rash with vitamin A injections. This reaction has only been reported in one case series of 3 patients in the published literature. Her case highlights the importance of vitamin deficiency screening in patients after bariatric surgery, and her skin reaction to the injections is a unique side effect that is not frequently observed.

Abstract
BACKGROUND Biliopancreatic diversion with duodenal switch (BPD-DS) decreases vitamin D and calcium absorption, which may result in secondary hyperparathyroidism. This study aimed at evaluating the prevalence of vitamin D deficiency and secondary hyperparathyroidism before and after BPD-DS. METHODS A retrospective analysis of patients who had undergone BPD-DS at a tertiary bariatric center between 2003 and 2010 and for whom simultaneous measurements of serum 25-hydroxyvitamin D and parathyroid hormone were available within 5 years post-op was performed. The prevalence of vitamin D deficiency (< 20 ng/ml) and secondary hyperparathyroidism (> 65 pg/mL) at different time points was calculated. RESULTS Included were 1436 patients (mean ± SD, age 42.7 ± 10.4 years; BMI 51.5 ± 8.6 kg/m2; 69.8% women). Prevalence of vitamin D deficiency decreased up to 6-12 months after surgery (from 35.8% at baseline down to 6-9%) then rose progressively, plateauing at 15.5% after 36 months. Prevalence of hyperparathyroidism was 28.5% before surgery and rose progressively after surgery, reaching 68.6% at 5 years. Mean serum corrected calcium increased from 0 to 6 months then decreased up to 36 months. Preoperatively, the prevalence of hypocalcemia was 7.3%. It increased after 12 months, attaining 26.9% at 48 months. CONCLUSIONS Prevalence of vitamin D deficiency and secondary hyperparathyroidism is high before BPD-DS. Despite a low prevalence of vitamin D deficiency after surgery, prevalence of hyperparathyroidism increased steadily 1 year after surgery, preceded by a decrease in serum calcium. Factors explaining the high prevalence of secondary hyperparathyroidism after BPD-DS and its long-term impact on bone health should be addressed.

Abstract
Obesity is a chronic life-threatening disease, and bariatric surgery is the most effective treatment in those patients. The two main operations are laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB). LSG carries a smaller risk for nutritional deficiencies, while gastric bypass procedures are associated with increased nutritional deficiencies because the procedure is more complex and changes the gastrointestinal anatomy. Recent studies comparing LSG and RYGB have proven that these types of operation may lead to a similar weight reduction effect but cause different micronutrient deficiencies. Types of malnutrition after bariatric surgery include protein-energy malnutrition and deficiencies of micronutrients, such as iron, folate, vitamin A, and vitamin B<sub>12</sub>. Bariatric patients who do not adhere to the recommended diets are at a greater risk of developing relevant malnutrition. Therefore, life-long postoperative clinical and laboratory monitoring is necessary to diagnose deficiencies of vitamins, trace elements, and minerals and to correct them with supplements. Unfortunately, no standardized aftercare regimes exist for these patients, and the costs for nutritional supplements are paid by the patients themselves.
