Personal, external, and psychological factors influencing adherence to nutrition and diet in patients undergoing metabolic/bariatric surgery: a systematic synthesis of mixed methods research. Acta Diabetol 2024:10.1007/s00592-024-02319-9. [PMID: 38888635 DOI: 10.1007/s00592-024-02319-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 06/06/2024] [Indexed: 06/20/2024]
Abstract
AIMS To offer a holistic view of the personal, external, and psychological factors influencing adherence to nutrition and diet in patients undergoing metabolic/bariatric surgery. METHODS This systematic synthesis of mixed methods research involved a comprehensive search for articles in English databases, including PubMed, Cochrane Library, Web of Science, EBSCO, Scopus, and Embase, as well as Chinese databases. The search encompassed articles published from the inception of the database up to June 2023. Following the evaluation of literature quality and extraction of relevant information from the selected studies, data from both quantitative and qualitative studies were integrated. The extracted data were analyzed separately, and themes were identified and summarized to elucidate the factors influencing adherence to nutritional and dietary guidelines. The methodology adhered to the guidelines recommended by the Joanna Briggs Institute (JBI) for mixed methods systematic evaluations. RESULTS Three themes and their corresponding descriptive elements were identified, including: (1) Personal factors: subjective factors (attitude, capability, awareness, behaviors), objective factors (age, sex, work status, economic level, physical activity, dietary habits, weight change); (2) External factors: medication (quantity of pills, complexity of intake times, side effects, unpleasant smell or taste), surgery factor, social influences (family members, dietitians, and peers); (3) Psychological factors: self-efficacy, attachment anxiety, and mental health problems. CONCLUSIONS The synthesis provided a comprehensive overview of the factors influencing postoperative compliance of nutrition and diet among patients undergoing metabolic and bariatric surgery. It emphasizes the necessity for clinical staff to tailor interventions based on these diverse factors, as well as to attach importance to patients' mental health, giving multidimensional dietary guidance and health care.

Abstract
PURPOSE OF REVIEW The purpose of this review and meta-analysis is to characterize the changes in body composition of children and adolescents who underwent bariatric surgery and identify possible negative effects of performing this procedure during pediatric ages. RECENT FINDINGS Bariatric surgery in children and adolescents is an emerging strategy to promote higher and faster body weight and fat mass losses. However, possible negative effects usually observed in surgical patients' muscle-skeletal system raise a major concern perform this intervention during growth. Despite these possible issues, most experimental studies and reviews analyze bariatric surgery's effectiveness only by assessing anthropometric outcomes such as body weight and BMI, disregarding the short- and long-term impact of bariatric surgery on all body composition outcomes. Bariatric surgery is effective to reduce fat mass in adolescents, as well as body weight, waist circumference, and BMI. Significant reduction in lean mass and fat-free mass is also observed. Bone mass seems not to be impaired. All outcomes reduction were observed only in the first 12 months after surgery. Sensitivity analysis suggests possible sex and type of surgery-related differences, favoring a higher fat mass, body weight, and BMI losses in boys and in patients who underwent RYGB.

Abstract
BACKGROUND Thiamine deficiency (TD) among adolescents following metabolic and bariatric surgery (MBS) has not been assessed. OBJECTIVE We assessed TD among adolescents following MBS. SETTING University Hospital. METHODS A retrospective chart review was conducted for all adolescents and young adults (aged 10-25 years) who had MBS and subsequently presented with TD at our institution (n = 30). Diagnosis used clinical, laboratory, brain imaging, and neurophysiology criteria. Of 1575 patients, 7 subsequently had TD. Another 23 adolescents had MBS at private hospitals or overseas and presented at our institution with TD. RESULTS Based on MBS undertaken at our institution, TD prevalence was .45 cases per 100 MBS. The mean age of patients was 19.5 ± 3.23 years, 53.3% were male, 96.7% had sleeve gastrectomy, and time from MBS to admission averaged 4.97 ± 11.94 months. Mean weight loss from surgery to admission was 33.68 ± 10.90 kg. Associated factors included poor oral intake (90%), nausea and vomiting (80%), and noncompliance with multivitamins (71%). Signs and symptoms included generalized weakness, nystagmus, numbness, and paraparesis (83.3%-80%). Seven patients had Wernicke encephalopathy full triad; 16 displayed a mixed picture of Wernicke encephalopathy and dry beriberi; and there were no cases of wet beriberi. Half the patients achieved complete resolution of symptoms, whereas 47% and 40% had residual weakness or persistent sensory symptoms, respectively. There was no mortality. Most common concurrent nutritional deficiencies were of vitamins K, D, and A. CONCLUSIONS This is the first in-depth study of TD among adolescents after MBS. Although TD is uncommon among adolescents after MBS, it is serious, requiring diligent suspicion and prompt treatment. Bariatric teams should emphasize compliance with multivitamin regimens and follow it up.

Using the 5-Item Medication Adherence Report Scale (MARS-5) to Screen for Non-adherence to Vitamin and Mineral Supplementation After Bariatric Surgery. Obes Surg 2024; 34:576-582. [PMID: 38177555 PMCID: PMC10810978 DOI: 10.1007/s11695-023-07027-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 12/20/2023] [Accepted: 12/20/2023] [Indexed: 01/06/2024]
Abstract
INTRODUCTION Poor adherence to recommended vitamin and mineral supplementation after bariatric surgery is common and challenging for healthcare professionals to identify. There are several questionnaires for self-reporting of adherence to chronic medication, but none has so far been evaluated for assessment of adherence to vitamin and mineral supplementation after bariatric surgery. The aim of this study was to assess the accuracy of the 5-item Medication Adherence Report Scale (MARS-5) in measuring adherence to vitamin and mineral supplementation post bariatric surgery (gastric bypass or sleeve gastrectomy). METHOD The psychometric properties of MARS-5 for vitamin and mineral supplementation were validated in two cohorts: one at 1 year post bariatric surgery (n = 120) and the other at 2 years post-surgery (n = 211). MARS-5 was compared to pharmacy refill data for vitamin B12 and combined calcium/vitamin D as reference. RESULTS Correlation analyses demonstrated that the MARS-5 had acceptable validity compared to objectively measured adherence rates from pharmacy refill data (calculated as continuous, multiple-interval measures of medication availability/gaps-coefficient ranged from 0.49 to 0.54). Internal reliability (Cronbach's α) was high: 0.81 and 0.95, respectively. There was a clear ceiling effect where one out of three had a maximum score on MARS-5. CONCLUSION MARS-5 demonstrated acceptable psychometric properties for assessment of adherence to vitamin and mineral supplementation post bariatric surgery.

Twelve-Month Outcomes after Metabolic and Bariatric Surgery among Youths Participating in a Structured Preparation and Follow-Up Program: Results of the Youth with Extreme Obesity Study. Obes Facts 2023; 17:59-71.

Abstract
INTRODUCTION While invasive and associated with risks, metabolic and bariatric surgery (MBS) can promote sustained weight loss and substantial health benefits in youths with extreme obesity. The path toward informed decision making for or against MBS is poorly characterized and postoperative follow-up to assess risks and benefits is inconsistent. In youths with extreme obesity, we aimed to evaluate decision making toward MBS, as well as MBS outcomes and adherence with follow-up and recommendations in the setting of a structured pre- and post-MBS program. METHODS Participants were recruited in the setting of the multicenter "Youth with Extreme Obesity Study" (YES). YES is a cohort study in adolescents and young adults aged 14-24 years with obesity (BMI ≥30.0 kg/m2) who were recruited at four medical centers and one job center in Germany between 2012 and 2018. Participants at two medical centers with BMI ≥35 kg/m2, aged 14-24 years, and interested in pursuing MBS were included in the subproject 3 "Safety and effectiveness of weight loss surgery in adolescents with severe obesity within a structured pre- and post-surgery treatment program - an observational study" that comprised a 2-months pre- and 12-months post-MBS program. RESULTS Twenty-eight of 169 youths (17%) with BMI ≥35 kg/m2 were interested in MBS. Twenty-six fulfilled published eligibility criteria for MBS and participated in the structured pre-MBS preparation program. Of these, 9 participants (2 females) decided against, and 17 (n = 11 females) decided for MBS (sleeve gastrectomy). The 12-month follow-up rate was high (16/17 [94%]) and all participants achieved significant weight reduction (ΔBMI: -16.1 ± 5.6 kg/m2). Eleven of 16 participants (69%) reported taking the prescribed dietary supplements in the first year after MBS, but only five of them (31%) did so daily. In contrast to the high 12-month retention rate, follow-up after completion of the structured program was low at 24-months (9/16 [56%]) and at 36-months (5/15 [36%]), respectively. CONCLUSION Participants demonstrated active decision making for or against MBS and high adherence with the structured pre- and 12 months post-MBS program, but participation was low thereafter. These findings endorse the need for longer term structured post-MBS programs to capture long-term outcomes and provide adequate care in this vulnerable group at the transition to adulthood.

Abstract
PURPOSE Metabolic bariatric surgery (MBS) is increasingly accepted as a treatment for severely obese adolescents. However, its long-term efficacy and safety are not well characterized, particularly in the Eastern Asian population. We aimed to explore the long-term effects of MBS on Chinese adolescents with severe obesity. METHODS A total of 44 obese adolescents (≤18 years old) underwent MBS at our institution from May 2011 to May 2017. A matched nonsurgical control group, including 43 patients, was recruited from lifestyle modification programs in the same period. All patients completed assessments at presurgery/baseline and five years after surgery. The data were collected and analyzed using the χ2 test and an independent sample t-test. RESULTS Comparing the surgical and control groups revealed that the surgical patients showed significant weight loss and improvement in comorbidities, while the nonsurgical patients showed a trend of weight gain and increased comorbidities (p < .05). Furthermore, the surgical patients had a higher composite physical quality of life (as determined by the Short Form-36 questionnaire). On the other hand, the patients who underwent MBS had a higher risk of malnutrition. DISCUSSION Compared with nonsurgical patients, severely obese adolescents who undergo MBS exhibit more effective long-term weight loss, remission of comorbidities, and improved quality of life. Furthermore, more attention should be paid to helping adolescents avoid malnutrition after they undergo MBS.

Abstract
INTRODUCTION In France, approximately 100 obese adolescents undergo a bariatric procedure every year. To date, only data from laparoscopic adjustable gastric banding (LAGB) or sleeve gastrectomy (SG) have been published. Our objective was to report the outcomes of a series of French obese adolescents who underwent a Roux-en-Y gastric bypass (RYGB). METHODS We included all obese adolescents aged 13-19 years who underwent RYGB in our department from 2008 with at least 2 years of follow-up after surgery. We analyzed the course of the anthropometric data, comorbidities, and subsequent adverse events. RESULTS Starting in September 2008, out of 93 obese adolescents who requested bariatric surgery, 39 (35%) underwent a bariatric procedure. From these adolescents, 2-year follow-up data were available for 26 patients who had a RYGB. At the time of surgery, the mean patient age was 17.4 years (standard deviation [SD]=1.4) and the body mass index (BMI) was 52.0 kg/m² (SD=7.8). One patient was lost to follow-up. At 2 years after surgery, the mean BMI was 35.7 kg/m² (SD=9.4) with a mean decrease in BMI of 31.9% (SD=11.6). Comorbidities improved for most of the patients: high blood pressure (2/2) and pseudotumor cerebri (1/1) were cured after surgery, and dyslipidemia improved globally. The complications observed were anemia, abdominal pain requiring celioscopy (n = 2), and oxalic nephrolithiasis. CONCLUSION Only one third of the obese adolescents requesting bariatric surgery were operated on. Our series including exclusively obese adolescents who underwent an RYGB presents the results of this technique on weight loss and comorbidities; mechanical and nutritional complications remain uncommon. These results are similar to those obtained in studies of adult patients.

Abstract
OBJECTIVE Large studies comparing outcomes between laparoscopic sleeve gastrectomy (LSG) and one anastomosis gastric bypass (OAGB) are scarce and involve adult populations. The aim of the study was to compare perioperative, early postoperative, and 1-year postoperative outcomes of adolescents with obesity who underwent LSG or OAGB surgery. METHODS The medical records of adolescents with obesity who underwent LSG or OAGB at the Tel Aviv Sourasky Medical Center from January 2017 to January 2021 were retrospectively reviewed. Data on their gastrointestinal (GI) symptoms and postoperative quality of life were obtained by a telephone interview. RESULTS Included were 75 adolescents (median [interquartile range, IQR] age 17.3 [16-18] years) of whom 22 underwent OAGB and 53 underwent LSG. There were no significant preoperative group differences in age, sex, and body mass index score. A low rate of perioperative (5.7% vs 0) and postoperative complication (15.1% vs 10%) with no statistical differences between LSG and OAGB group, respectively, was noted. At 12 months, the percent excessive weight loss + IQR was 42.40% [30.00, 45.00] and 38.00% [33.550, 44.20] in the LSG and OAGB group, respectively ( P = NS). The results of the Pediatric Quality of Life Inventory Gastrointestinal Symptoms scale revealed significantly less food limitation and heartburn after OAGB compared to LSG (food limitation 71.63 vs 53.85 and heartburn 83.654 vs 61.6, P = 0.03 and P = 0.029, respectively). CONCLUSIONS Both surgeries are effective and safe for weight loss in the adolescent population. OAGB was associated with significantly fewer GI symptoms compared to LSG.

Abstract
BACKGROUND Bariatric procedures increase patient risk of long-term metabolic complications primarily due to nutrient deficiencies. The mainstay of prevention includes routine vitamin and mineral supplementation; however, patient-reported barriers to daily compliance are poorly understood. METHODS Post-bariatric surgery patients electively participated in an 11-point outpatient survey at a single academic institution. Surgical procedures included either laparoscopic sleeve gastrectomy (SG) or gastric bypass (GB). At the time of survey, patients ranged from 1-month to 15 years from surgery. Survey items consisted of dichotomous (yes/no), multiple choice, and open-ended free response questions. Descriptive statistics were evaluated. RESULTS Two hundred and fourteen responses were collected, 116 (54%) underwent SG and 98 (46%) underwent GB. Of these, 49% of samples were during short-term postoperative follow-up visits (0-3 months), 34% intermediate follow-up (4-12 months), and 17% long-term follow-up (> 1 year). A total of 98% of patients reported that insurance did not cover their supplement cost. Most patients reported current vitamin use (95%), with 87% reporting daily compliance. Daily compliance was observed in 94%, 79%, and 73% of SG patients at short-, intermediate-, and long-term follow-up visits, respectively. While GB patients reported daily compliance in 84%, 100%, and 92% of short, intermediate, and long-term responses. Of those who were unable to take vitamins daily, non-compliance was attributed most to forgetting (54%), and less often to side effects (11%), or taste (11%). Patient-reported strategies for remembering to take vitamins included tying into daily routine (55%), use of a pill box (7%), and alarm reminders (7%). CONCLUSIONS Daily compliance with post-bariatric surgery vitamin supplementation does not appear to vary based on postoperative time-period or surgical procedure. While a minority of patients struggle with daily compliance, factors associated with non-compliance include patient forgetting, side effects, and taste. Widespread utilization of patient-reported daily reminder strategies may lead to improved overall compliance and reduce incidence of nutritional deficiencies.

Associations of age, sex, and socioeconomic status with adherence to guideline recommendations on protein intake and micronutrient supplementation in patients with sleeve gastrectomy or Roux-en-Y gastric bypass. PLoS One 2023; 18:e0282683. [PMID: 36867644 PMCID: PMC9983924 DOI: 10.1371/journal.pone.0282683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 02/21/2023] [Indexed: 03/04/2023] Open
Abstract
INTRODUCTION Patients with bariatric surgery often show poor long-term compliance to recommendations for prevention of nutrient deficiency but it is unclear which factors contribute. We investigated the associations of age, sex, and socioeconomic status (SES) with adherence to guideline recommendations on protein intake and micronutrient supplementation. METHODS In a monocentric cross-sectional study we prospectively recruited patients with sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) and a minimum postoperative period of 6 months. Clinical and demographic data were obtained from the patients' medical files and by questionnaire. Patients reported on supplement usage, recorded their dietary intake for seven days and underwent physical examinations including blood testing. RESULTS We included 35 patients (SG: n = 25, RYGB: n = 10) with a mean (+SD) postoperative period of 20.2 (±10.4) months. Distributions of age, sex and SES were comparable between the SG and RYGB groups. Non-adherence to recommended protein intake was associated with age ≥ 50 years (p = 0.041) but not sex or SES. Protein intake inversely correlated with markers of obesity. There were no significant associations of age or sex with micronutrient supplementation. Only for vitamins A (p = 0.049) and B1 (p = 0.047) higher SES was associated with greater compliance. The only manifest deficiency associated with non-adherence to micronutrient supplementation was that for folic acid (p = 0.044). CONCLUSION In patients after bariatric surgery, those of older age and of lower SES might have a greater risk of unfavorable outcome and may require greater attention to micronutrient and protein supplementation.

Abstract
OBJECTIVE This trial evaluated a smartphone application's effectiveness in improving adherence to vitamin and mineral supplementation postoperatively. METHODS This study was a randomized controlled trial comprising 140 patients undergoing bariatric surgery (gastric bypass or sleeve gastrectomy). Participants were randomized 1:1 to the 12-week intervention, using the smartphone application PromMera, or to standard care. The primary end point was adherence to vitamin and mineral supplementation. RESULTS Initiation rate and overall adherence to supplementation were high in both groups. Change in objectively measured adherence rate from before the intervention to 1 year post surgery, measured with pharmacy refill data, did not differ between groups for vitamin B12 (-9.6% [SD = 27%] vs. -9.3% [SD = 30%]; p = 0.48) or calcium/vitamin D (-12.3% [SD = 29%] vs. -11.5% [SD = 32%]; p = 0.44). A modest effect on the secondary end point (subjectively measured adherence, using the Medication Adherence Report Scale-5) was seen immediately after the intervention (intervention group 0.00 [SD = 1.3] vs. control group -1.2 [SD = 3.5]; p = 0.021), but this effect did not persist 1 year post surgery. No differences were detected in the prevalence of biochemical deficiencies. CONCLUSIONS The use of the smartphone application PromMera did not obtain a lasting improvement in adherence to vitamin and mineral supplementation 1 year post bariatric surgery.

Abstract
BACKGROUND Lifelong vitamin and mineral supplementation is recommended after bariatric surgery to prevent nutritional deficiencies, but it is not clear to which extent patients adhere to the recommended medication. The aim of this study was to assess adherence to supplementation. Additionally, we assessed predictors of low adherence and biochemical deficiencies. METHODS 263 adults were followed two years post bariatric surgery (89.4 % Roux-en-Y gastric bypass, 10.6 % sleeve gastrectomy) regarding adherence to calcium-vitamin D, vitamin B12 and iron. Pharmacy refill data was used to objectively capture adherence-rate. Predictors of low adherence were assessed via questionnaires and medical records. Blood sampling was performed preoperatively, and 1- and 2-years post-surgery. RESULTS About 60 % of the study participants had high adherence-rate (≥ 80 %) two years post-surgery, but a significant proportion had discontinued the intended lifelong supplementation: 15 % for calcium-vitamin D and 12 % for B12. Biochemical deficiencies were uncommon two years after surgery, both in adherent and non-persistent subjects, except for a 10 % prevalence of anemia. Younger age, experience of side effects, mental health problems and no regular use of medication before surgery, were factors associated with low adherence. CONCLUSION Substantial variation existed in adherence to supplementation regimens after bariatric surgery during the first two years after bariatric surgery, but biochemical deficiencies were rare. The results indicate need for tailored follow-up and strategies to support long-term persistence.

Abstract
BACKGROUND Nutritional supplementation is recommended as a prophylactic strategy for nutritional deficiencies after bariatric surgery. Little is known regarding compliance and patients' perspectives. The purpose of the study was to explore supplement intake, compliance, and patients' perspectives (including barriers, facilitators, and beliefs) and to examine whether compliance to nutritional supplementation can be predicted after bariatric surgery. MATERIAL AND METHODS: A questionnaire was developed to explore supplement intake and patients' perspectives. The Probabilistic Medication Compliance Scale (ProMAS) was included and modified to measure behaviors related to supplementation compliance. Content validity was assessed with an expert and patient panel. Consequently, a cross-sectional survey was conducted among patients that underwent bariatric surgery, who were invited using social media. Descriptive statistics and Spearman correlations were applied. Multiple linear regression analysis was performed to predict compliance. RESULTS A 58-item questionnaire was developed and content validated, resulting in a scale-content validity index of 0.93. The questionnaire was completed by 402 subjects. Sixty-nine subjects reported not consuming any nutritional supplement (n = 69; 17.2%). For the supplement users (n = 333; 82.8%), a median ProMAS sum score of 11.0 (7.0-15.0) was observed. Increasing age and medicine intake were positive predictors of compliance (age: B = 0.058, p = 0.01; medicine intake: B = 0.39, p < 0.001), while experiencing barriers was identified as a negative predictor of compliance (B = - 4.637, p < 0.001). Top three barriers for supplement use were forgetfulness (n = 118; 29.4%), too expensive (n = 91; 22.6%), and experiencing side effects (n = 61; 15.2%). CONCLUSION Lifelong nutritional supplementation is essential after bariatric surgery, but compliance can be affected by the presence of barriers.

Abstract
BACKGROUND Globally, only two studies appraised the long-term nutritional status of adolescents after laparoscopic sleeve gastrectomy (LSG). METHODS Retrospective chart review of all adolescents aged ≤ 18 years who underwent LSG with ≥ 5 years follow-up and had no subsequent revisional surgery (N = 146). We assessed 15 nutritional parameters preoperatively and at 1, 3, 5, 7, and 9 years post surgery. RESULTS Mean age was 16.51 ± 1.29 years, 51% were males. We identified three patterns: 1) Significant worsening of preoperative deficiencies: 4.7% and 0.8% of the sample exhibited zinc and vitamin B12 deficiencies, worsening to 20.8% and 12.8% at 1 year, respectively. Likewise, 0.7% of the sample had low total protein, worsening to 8.3% at year 3. A total of 32.4% of females had preoperative low hemoglobin worsening to 57.9% at year 5. 2) Significant improvement: the percentage of males with preoperative low hemoglobin (5.6%) was reduced to 4.1% and 5.1% at years 1 and 3, respectively. 3) Persistent deficiency: all (100%) of adolescents had preoperative vitamin D deficiency that persisted through years 3 and 9 at 90.5% and 100%, respectively. The most common complications were food intolerance (51%), vomiting (47.5%), gastritis/ esophagitis (35.7%), and gastroesophageal reflux disease (20.3%). We observed one case of Wernicke's encephalopathy. Across the 9 years, 15.4% of the adolescents underwent intra-abdominal surgeries where 12.6% had cholecystectomy and one patient had appendectomy. CONCLUSION Adolescents had several preoperative nutritional deficiencies, most of which worsened or persisted on the long term. This is the first study among adolescents to assess such deficiencies beyond 5 years.

Abstract
BACKGROUND Nutritional deficiencies among adolescents undergoing bariatric surgery (BS) have not been evaluated a in relation to patient's sex. OBJECTIVES We compared the preoperative nutritional profile of adolescents characterized by sex and single versus multiple deficiencies. SETTING University hospital. METHODS Cross-sectional retrospective chart review of 415 eligible adolescents who underwent primary BS between 2011 and 2020. Data included preoperative demographic, anthropometric information as well as three sets of nutritional variables: anemia-related, calcium-related, and other nutritional variables. RESULTS The sample comprised 247 males (59.5%) with a mean age of 15.89 ± 1.03 years and a mean body mass index (BMI) of 47.80 ± 6.57 kg/m2. Most common deficiencies were vitamin D (92.3%), albumin (51.8%), anemia (15.9%), zinc (11.1%), and vitamin B12 (8%); 21.7% had hyperparathyroidism. Females exhibited a significantly higher prevalence of low hemoglobin, low hematocrit, and iron deficiency. Multiple deficiencies were present among 97.6%, 73.2%, 23.6%, 15%, and 12.6% of adolescents, who had vitamin D, albumin, hemoglobin, zinc, and vitamin B12 deficiencies, respectively. Univariate analysis revealed that adolescents with a BMI of ≥50 kg/m2 were 1.24 times more likely to have multiple deficiencies (P = .004). Using multivariate log-binomial regression, BMI of ≥50 kg/m2 was a significant predictor of multiple nutritional deficiencies (P = .005, adjusted risk ratio = 1.23, 95% CI 1.06-1.42). Age and sex were not independent predictors of multiple nutritional deficiencies. CONCLUSION To our knowledge, this study is the first to appraise single and multiple nutritional deficiencies in adolescents undergoing BS by sex. Multiple deficiencies were common. Females are at higher risk of anemia-related deficiencies. A BMI of ≥50 kg/m2 independently and significantly predicted multiple nutritional deficiencies. Correction before and monitoring after surgery are important.

Abstract
Purpose In our centre, specialized high dose multivitamin supplementation designed to meet the needs of patients after gastric bypass surgery is routinely recommended in the early postoperative period. The aim of the present study was to analyse whether iron supplementation prescribed in clinical practice is sufficient in both sexes and whether multivitamin supplementation standardized for women might potentially lead to iron overload in men. Materials/Methods This was a retrospective study covering the period up to 36 months after bariatric surgery. Three groups were compared (men, premenopausal and postmenopausal women). The iron status was evaluated employing serum ferritin concentrations. Results A total of 283 patients who had at least one follow-up visit between January 2015 and April 2018 at a specialized academic outpatient centre were included (71 men, 130 premenopausal women, 82 postmenopausal women). Thirty-six months after surgery, 33.3%, 68.4% and 54.5% of the men, pre- and postmenopausal women, respectively, were iron deficient. The preoperative prevalence of excess ferritin levels was 13.7% in premenopausal, 3.0% in postmenopausal women, 5.7% in men and declined in the following months. Conclusion Iron deficiency is very common after gastric bypass surgery, and even high dosages of multivitamin and mineral supplements might not be sufficient to prevent the development of iron deficiency. Men, pre- and postmenopausal women differ in their prevalence of iron deficiency which demands adapted iron dosage regimens based on the sex and the age. Iron overload is rare in all observed groups and highest in premenopausal women. Graphical abstract ![]()

Abstract
Obesity and the corresponding burden of related diseases is a major public health issue worldwide that is reaching pandemic proportions. Bariatric surgery is the only intervention that has been shown to result in substantial and lasting weight loss, and a decrease in overall mortality for patients with severe obesity. Consequently, the population of patients having undergone this procedure is increasing. Multifactorial weight-dependent and independent mechanisms underlying metabolic diseases could also drive preventable, but potentially life-threatening, long-term nutritional complications. However, given post-bariatric patients are prone to functional gastrointestinal symptoms and substantial weight loss, nutritional complications might be challenging. This Review is focused on the prevention and treatment of nutritional complications after bariatric surgery in the clinical setting.

Abstract
PURPOSE This study was aimed to develop a questionnaire to assess the determinants of dietary adherence among patients after bariatric surgery based on the attitude-social influence-efficacy (ASE) model and to evaluate its psychometric properties. PATIENTS AND METHODS According to semi-structured interview, Delphi expert consultation and pilot study, the initial questionnaire was formed and applied to investigate 319 patients after bariatric surgery in a tertiary hospital in Jiangsu Province, China. The reliability and validity of the scale were tested. RESULTS The 28-item of the attitude-social influence-efficacy questionnaire after bariatric surgery (ASEQBS) was formed. The results of exploratory factor analysis showed that four factors, including intention, attitude, social influence, and self-efficacy, could be extracted, and the cumulative variance contribution rate reached 59.98%. Confirmatory factor analysis showed the model fit well. The content validity index of each item was 0.800-1.000, and the content validity index of the ASEQBS was 0.857. The total Cronbach's α of the ASEQBS was 0.920, the split-half reliability was 0.774, and the retest reliability was 0.922. CONCLUSION The results suggest that ASEQBS is a valid and reliable measure of determinants of dietary adherence. It may be useful to evaluate the influence factors of dietary adherence and helpful to evaluate the efficacy of tailored dietary intervention programs.

The effects of adolescent laparoscopic adjustable gastric band and sleeve gastrectomy on markers of bone health and bone turnover. Clin Obes 2020; 10:e12411. [PMID: 32896095 PMCID: PMC7935448 DOI: 10.1111/cob.12411] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 08/19/2020] [Accepted: 08/20/2020] [Indexed: 12/11/2022]
Abstract
25-hydroxy vitamin D (25 OHD) deficiency and secondary hyperparathyroidism have been seen after metabolic and bariatric surgery, but data are lacking on the bone health outcomes of adolescent sleeve gastrectomy (SG). The purpose of this study was to examine bone-related nutrition after SG, compared to laparoscopic adjustable gastric band (LAGB), and trend bone turnover markers following SG. This is an observational study of 197 adolescents who underwent LAGB (n = 98) or SG (n = 99). Bone health labs were collected at baseline and 6 and/or 12 months after LAGB or SG, with additional analysis of bone turnover markers in the SG group. Calcium and 25 OHD levels increased at 6 and 12 months after LAGB and SG, with no difference between the surgeries. Parathyroid hormone levels decreased only in the SG group. SG patients had increased osteocalcin and carboxy-terminal cross-linking telopeptide of type 1 collagen (CTX) at 6 and 12 months post-SG, although CTX decreased between 6 and 12 months. Excess weight loss at 6 months predicted the rise in CTX, but the changes in osteocalcin and CTX could not be attributed to 25 OHD deficiency, hypocalcemia or hyperparathyroidism. Patients had improved 25 OHD levels post-surgery, which may be secondary to stringent vitamin supplementation guidelines. However, there were marked increases in bone turnover markers following SG. More studies are needed to evaluate the effects of SG on adolescent bone health and to correlate the early changes in bone turnover with bone mineral density and fracture risk.

BMC Surg 2020; 20:232. [PMID: 33046020 PMCID: PMC7549200 DOI: 10.1186/s12893-020-00880-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 09/23/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Bariatric surgery (BS) is considered as an effective solution to control morbid obesity. Food restrictions resulting from the operation may decrease dietary nutrient intakes, particularly during the first year after BS. This study mainly aimed to assess the adequacy of dietary nutrient intakes at 6th and 12th month after BS. METHOD Of the severely obese participants in the Tehran obesity treatment study in 2015-2016, 58 patients undergoing Roux-En-Y gastric bypass (N = 16) or sleeve gastrectomy (N = 42) were selected from Tehran Obesity Treatment Center. To assess the patients' dietary intake, a three-day, 24-h dietary recall was obtained on three unscheduled days (two non-consecutive weekdays and one weekend day) at 6th and 12th month after BS. To evaluate the adequacy of nutrient intake, the patients' intakes were compared to the current dietary reference intakes (DRIs), including estimated average requirements (EAR) or Adequate Intakes (AI). RESULTS The mean age of the participants (71% women) undergoing BS was 37 ± 8 years. Anthropometric parameters significantly decreased at the 12th month after BS. The percentage of energy from carbohydrate intake increased significantly between the 6th and 12th month after BS (P = 0.04). The mean ± SD of protein intake was lower than the recommended dosage with a dramatic decrease from 45 ± 30 to 31 ± 15 (g/day) between the two intervals (P = 0.001). The mean intake of saturated fatty acid (SFA) decreased dramatically (P < 0.001) from 6 to 12 month; however, the median intake of n3-polyunsaturated fatty acid (n3-PUFA) intake increased (P = 0.02). None of the participants showed nutrient intake adequacy in terms of biotin, fat soluble vitamins, pantothenic acid, potassium, and zinc. Moreover, less than 10% of the participants showed nutrient intake adequacy in terms of folate, magnesium, manganese, and calcium according to DRIs during the both intervals after BS. CONCLUSION Bariatric surgery can reduce dietary intakes, which is more obvious 12 months after the surgery. Out of 21 micronutrients, nearly all could not met the EAR and were received < 50%, also had significant reduction from the 6th to12th month after surgery.

Abstract
Morbid obesity is a growing problem worldwide and has subsequently resulted in a wide application of bariatric surgery to achieve long-term weight loss and improvement of obesity-related co-morbidities. In spite of these clinical benefits, vitamin deficiencies are common after bariatric surgery; therefore, lifelong multivitamin supplementation (MVS) is recommended. However, patient adherence to MVS intake is generally poor. The aim of this narrative review is to analyse which factors influence the adherence of MVS intake after bariatric surgery. To provide an extensive overview, we will discuss the different factors that influence MVS use in patients who underwent bariatric surgery, but also review the literature on MVS in other patient groups.

Abstract
Background To optimize postoperative outcomes after bariatric surgery, lifestyle changes including increased physical activity are needed. Micronutrient deficiency after surgery is also common and daily supplementation is recommended. Objective The aim of the PromMera study is to evaluate the effects of a 12-week smartphone app intervention on promotion of physical activity (primary outcome) and adherence to postsurgery vitamin and mineral supplementation, as well as on other lifestyle factors and overall health in patients undergoing bariatric surgery. Methods The PromMera study is a two-arm, randomized controlled trial comprising patients undergoing bariatric surgery. Participants are randomized postsurgery 1:1 to either the intervention group (ie, use of the PromMera app for 12 weeks) or the control group receiving only standard care. Clinical and lifestyle variables are assessed pre- and postsurgery after 18 weeks (postintervention assessment), 6 months, 1 year, and 2 years. Assessments include body composition using Tanita or BOD POD analyzers, muscle function using handgrip, biomarkers in blood, and an extensive questionnaire on lifestyle factors. Physical activity is objectively measured using the ActiGraph wGT3X-BT triaxial accelerometer. Results A total of 154 participants have been enrolled in the study. The last study participant was recruited in May 2019. Data collection will be complete in May 2021. Conclusions Implementing lifestyle changes are crucial after bariatric surgery and new ways to reach patients and support such changes are needed. An app-based intervention is easily delivered at any time and can be a key factor in the adoption of healthier behavioral patterns in this rapidly growing group of patients.

Abstract
Purpose Adherence to vitamin supplementation recommendations after bariatric surgery is generally poor, which is associated with nutritional deficiencies. Patients’ own perspectives and reasons for poor adherence to vitamin supplementation recommendations have not yet been studied in depth. The purpose of this study was first to measure the accuracy of self-reported adherence to supplementation recommendations by using objective measures of vitamin D levels in blood and thereafter to explore perceptions of barriers and facilitators to participants’ adherence to supplementation recommendations. Material and Method Participants were recruited from a prospective study investigating the outcome of bariatric surgery in adolescents with severe obesity. Mixed methods were used, including a quantitative part where vitamin D levels were analysed through 25(OH)D levels in blood and/or a questionnaire on adherence to supplementation programmes 5 years after surgery (n = 40) plus a qualitative part with semi-structured interviews (n = 20). Results We found a convergence between self-reported adherence to vitamin supplementation and vitamin D 25(OH)D levels in blood indicating honestly in self-reported responses. The qualitative evaluations resulted in the categories awareness and personal capability and external factors. In the analysis, an overall theme emerged; capacity is crucial for adherence in youth who have undergone bariatric surgery. Conclusion Bariatric surgery is a comprehensive procedure that requires lifelong treatment afterwards. There is coherence between what adolescents actually do and what they say they do. Capacity is crucial for adherence and social support has been shown to be important.

Nutritional Risks in Adolescents After Bariatric Surgery. Clin Gastroenterol Hepatol 2020; 18:1070-1081.e5.

Abstract
BACKGROUND & AIMS Little is known about prevalence and risk factors for nutritional deficiencies in adolescents after metabolic bariatric surgery. We performed a 5-year prospective cohort study of these. METHODS Adolescents who had Roux-en-Y gastric bypass (RYGB, n = 161) or vertical sleeve gastrectomy (VSG, n = 67) were enrolled at 5 tertiary-care centers from March 2007 through February 2012. The final analysis cohort included 226 participants (161 who had RYGB and 65 who had VSG). We measured serum levels of ferritin; red blood cell folate; vitamins A, D, B1, B12; and parathyroid hormone at baseline and annually for 5 years. General linear mixed models were used to examine changes over time and identify factors associated with nutritional deficiencies. RESULTS The participants were 75% female and 72% white, with a mean age of 16.5 ± 1.6 years and mean body mass index of 52.7 ± 9.4 kg/m2 at surgery. Mean body mass index decreased 23% at 5 years, and did not differ significantly between procedures. After RYGB, but not VSG, serum concentrations of vitamin B12 significantly decreased whereas serum levels of transferrin and parathyroid hormone increased. Ferritin levels decreased significantly after both procedures. Hypo-ferritinemia was observed in 2.5% of patients before RYGB and 71% at 5 y after RYGB (P < .0001), and 11% of patients before VSG and 45% 5 y after VSG (P = .002). No significant changes in serum levels of folate or vitamins A, B1, or D were found between baseline and 5 y after either procedure. By 5 y, 59% of RYGB and 27% of VSG recipients had 2 or more nutritional deficiencies. Risk factors associated with specific deficiencies included surgery type, female sex, black race, supplementation intake, weight regain, and for females, pregnancy. CONCLUSIONS In a prospective study of adolescents who underwent RYGB or VSG, we observed nutritional deficiencies by 5 y after the procedures-particularly in iron and B12 after RYGB. Ongoing nutrient monitoring and supplementation are recommended for all patients, but surgery type, supplementation intake, sex, and race might affect risk.

Abstract
BACKGROUND Adherence to post-bariatric surgery nutritional supplements can be poor and is associated with higher micronutrient deficiency rates. There is currently no available study specifically seeking patients' perspectives on the reasons behind poor adherence and how to address it. METHODS Bariatric surgery patients living in the UK were invited to take part in an anonymous survey on SurveyMonkey®. RESULTS A total of 529 patients (92.61% females, mean age 47.7 years) took part. Most of these patients had undergone either a Roux-en-Y gastric bypass (63.0%) or sleeve gastrectomy (24.0%). Most of the patients were in full-time (49.0%, n = 260/529) or part-time (15.7%, n = 83/529) employment. Approximately 54.0% (n = 287/529) of the respondents reported having trouble taking all their supplements. Males were significantly more likely to report complete compliance. The most important reported reason for poor compliance was difficulty in remembering (45.6%), followed by too many tablets (16.4%), side effects (14.3%), cost (11.5%), non-prescribing by GP (10.8%), bad taste (10.1%), and not feeling the need to take (9.4%). Patients suggested reducing the number of tablets (41.8%), patient education (25.7%), GP education (24.0%), reducing the cost (18.5%), and more information from a healthcare provider (12.5%) or a pharmacist (5.2%) to improve the compliance. CONCLUSIONS This study is the first attempt to understand patient perspectives on poor adherence to post-bariatric surgery nutritional recommendation. Patients offered a number of explanations and also provided with suggestions on how to improve it.

Abstract
OBJECTIVE The development of these updated clinical practice guidelines (CPGs) was commissioned by the American Association of Clinical Endocrinologists (AACE), The Obesity Society (TOS), American Society for Metabolic and Bariatric Surgery (ASMBS), Obesity Medicine Association (OMA), and American Society of Anesthesiologists (ASA) Boards of Directors in adherence with the AACE 2017 protocol for standardized production of CPGs, algorithms, and checklists. METHODS Each recommendation was evaluated and updated based on new evidence from 2013 to the present and subjective factors provided by experts. RESULTS New or updated topics in this CPG include: contextualization in an adiposity-based chronic disease complications-centric model, nuance-based and algorithm/checklist-assisted clinical decision-making about procedure selection, novel bariatric procedures, enhanced recovery after bariatric surgery protocols, and logistical concerns (including cost factors) in the current health care arena. There are 85 numbered recommendations that have updated supporting evidence, of which 61 are revised and 12 are new. Noting that there can be multiple recommendation statements within a single numbered recommendation, there are 31 (13%) Grade A, 42 (17%) Grade B, 72 (29%) Grade C, and 101 (41%) Grade D recommendations. There are 858 citations, of which 81 (9.4%) are evidence level (EL) 1 (highest), 562 (65.5%) are EL 2, 72 (8.4%) are EL 3, and 143 (16.7%) are EL 4 (lowest). CONCLUSIONS Bariatric procedures remain a safe and effective intervention for higher-risk patients with obesity. Clinical decision-making should be evidence based within the context of a chronic disease. A team approach to perioperative care is mandatory, with special attention to nutritional and metabolic issues.

Abstract
As metabolic and bariatric surgery (MBS) increasingly becomes a treatment of choice for adolescents with severe obesity, there is a need to understand how to deliver pre- and postoperative care in ways that maximize long-term safety and efficacy. This article describes major pre- and postoperative goals, lifestyle modification targets, and, when necessary, pharmacologic management strategies for adolescents undergoing MBS. Three categories of evidence were used-studies of pre- and postoperative interventions and factors influencing MBS outcomes in adolescents, studies of pre- and postoperative associations and interventions in adults, and studies of non-surgical weight management applicable to adolescents pursuing MBS. Finally, priority areas for future research within this topic are identified.

Abstract
OBJECTIVE The development of these updated clinical practice guidelines (CPG) was commissioned by the American Association of Clinical Endocrinologists, The Obesity Society, the American Society of Metabolic and Bariatric Surgery, the Obesity Medicine Association, and the American Society of Anesthesiologists boards of directors in adherence to the American Association of Clinical Endocrinologists 2017 protocol for standardized production of CPG, algorithms, and checklists. METHODS Each recommendation was evaluated and updated based on new evidence from 2013 to the present and subjective factors provided by experts. RESULTS New or updated topics in this CPG include contextualization in an adiposity-based, chronic disease complications-centric model, nuance-based, and algorithm/checklist-assisted clinical decision-making about procedure selection, novel bariatric procedures, enhanced recovery after bariatric surgery protocols, and logistical concerns (including cost factors) in the current healthcare arena. There are 85 numbered recommendations that have updated supporting evidence, of which 61 are revised and 12 are new. Noting that there can be multiple recommendation statements within a single numbered recommendation, there are 31 (13%) Grade A, 42 (17%) Grade B, 72 (29%) Grade C, and 101 (41%) Grade D recommendations. There are 858 citations, of which 81 (9.4%) are evidence level (EL) 1 (highest), 562 (65.5%) are EL 2, 72 (8.4%) are EL 3, and 143 (16.7%) are EL 4 (lowest). CONCLUSIONS Bariatric procedures remain a safe and effective intervention for higher-risk patients with obesity. Clinical decision-making should be evidence-based within the context of a chronic disease. A team approach to perioperative care is mandatory with special attention to nutritional and metabolic issues.

Bone metabolism, bone mineral density and low-energy fractures 10 years after Roux-en-Y gastric bypass. Bone 2019; 127:436-445. [PMID: 31323430 DOI: 10.1016/j.bone.2019.07.014] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Revised: 07/10/2019] [Accepted: 07/12/2019] [Indexed: 01/27/2023]
Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is a common surgical procedure for treatment of morbid obesity. RYGB induces considerable and sustained weight loss, and remission of obesity related-comorbidities. While studies have suggested negative effects of RYGB on bone health, long-term data are lacking. We aimed to evaluate the prevalence of aBMD below the expected range for age, osteopenia, osteoporosis and low-energy fractures in a defined patient cohort 10 years after RYGB. Secondly, we wanted to identify factors associated with increased risk of aBMD z-score or t-score of -1.1 or lower 10 years after RYGB. METHODS Patients undergoing RYGB surgery from June 2004 to December 2006 at the Department of Morbid Obesity and Bariatric Surgery, Oslo University Hospital, a tertiary referral centre for treatment of morbid obesity, were invited to a 10 year follow-up. Follow-up visits included morning fasting blood samples, clinical examination, anthropometric measures and dual energy X-ray absorptiometry (DXA). RESULTS Out of 194 patients eligible for the study, 124 attended the 10 year follow-up and 122 (63%) were examined with DXA. Mean (SD) age was 50.3 (9.0) years, 118 (97%) were of Caucasian ethnicity, 94 were females (77%), of whom 41 (44%) were postmenopausal. Secondary hyperparathyroidism (SHPT) was noted in 37 participants (31%) and vitamin D deficiency (value below 50 nmol/L) and insufficiency (value below 75 nmol/L) in 40 (33%) and 91 (75%), respectively. Among the 63 participants who were premenopausal females or males 49 years or younger the prevalence of areal bone mineral density (aBMD) in the lower range of normal (z-score -1.1- to -1.9) was 30% (n = 19) and aBMD below the expected range for age (z-score ≤ -2.0) was noted in 8% (n = 5). Among the 59 participants who were postmenopausal females or males 50 years or older, the prevalence of osteopenia (t-score -1.1 to -2.4) was 51% (n = 30) and osteoporosis (t-score ≤ -2.5) was 27% (n = 16). The bone resorption markers CTX-1 and PINP were higher in participants with aBMD z-score or t-score of -1.1 or lower compared to participants with aBMD z-score or t-score of -1.0 or higher. Preoperative hypothyroidism, or higher age, postmenopausal status, BMI < 35 kg/m2, SHPT or higher PINP levels at 10 year follow-up were independently associated with aBMD z-score or t-score of -1.1 or lower 10 years after RYGB. Eighteen participants (15%) reported a clinical low-energy fracture after RYGB. In addition, vertebral fracture assessment by DXA revealed that 10 participants (8%) had experienced at least one moderate to severe morphometric vertebral fracture. CONCLUSION Ten years after RYGB 27% of postmenopausal females and males 50 years or older were osteoporotic, and 8% of premenopausal females and males 49 years or younger exhibited aBMD below the expected range for age. The prevalence of fragility fractures was high. SHPT, higher age, postmenopausal status or higher PINP levels at 10 years and preoperative hypothyroidism were all independent risk factors for aBMD z-score or t-score of -1.1 or lower 10 years after RYGB.

Abstract
INTRODUCTION Previous biomedical studies identified many lifestyle exposures that could possibly represent risk factors for dementia in general or dementia due to Alzheimer's disease (AD). These lifestyle exposures are mainly mentioned in free-text electronic health records (EHRs). However, automatic extraction and assessment of these exposures using EHRs remains understudied. METHODS A natural language processing (NLP) approach was adopted to extract lifestyle exposures and intervention strategies from the clinical notes of 260 patients with clinical diagnoses of AD dementia and 260 age-matched cognitively unimpaired persons. Statistics of lifestyle exposures were compared between these two groups. The mapping results of the NLP extraction were evaluated by comparing the results with data captured independently by clinicians. RESULTS Thirty out of fifty-five potentially relevant lifestyle exposures were mentioned in our clinical note dataset. Twenty-two dietary factors and three substance abuses that were potentially relevant were not found in clinical notes. Patients with AD dementia were significantly exposed to more of the potential risk factors compared to the cognitively unimpaired subjects (χ2 = 120.31, p-value < 0.001). The average accuracy of the automated extraction was 74.0% in comparison with the manual review of randomly selected 50 sample documents. DISCUSSION AND CONCLUSION We illustrated the feasibility of NLP techniques for the automated evaluation of a large number lifestyle habits using free-text EHR data. We found that AD dementia patients were exposed to more of the potential risk factors than the comparison group. Our results also demonstrated the feasibility and accuracy of investigating putative risk factors using NLP techniques.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is an effective obesity treatment in adults and has become established in adolescents. Lower adherence to supplementation in adolescents confers a risk for long-term nutritional deficiencies. OBJECTIVES To assess adherence to supplementation, micronutrient intake, and biochemistry in adolescents through 5 years after RYGB. SETTING University hospitals, multicenter study, Sweden. METHODS Micronutrient intake and adherence to supplementation were assessed by diet history interviews and biochemistry preoperatively, 1, 2, and 5 years after RYGB in 85 adolescents (67% females), aged 16.5 years (± 1.2) with a body mass index of 45.5 kg/m2 (± 6.0). Adherence was defined as taking prescribed supplements ≥3 times a week. Micronutrient intake and biochemistry were compared with matched controls at 5 years. RESULTS Over 75% completed the dietary assessments across 5 years after RYGB. Adherence ranged between 44-61% through 5 years. At 5 years, ferritin and hemoglobin decreased (P < .04) and 61% had iron deficiency (P ≤ .001). Among females with iron deficiency, most did not adhere to supplementation (P = .005), and 59% of these had anemia (P < .001). Vitamin D insufficiency continued after surgery and 80% of participants who did not adhere to supplementation had insufficiency (P = .002). Adolescents not adhering had lower levels of vitamin D, B12, and ferritin (females) compared with both adhering adolescents and the control group (all P < .04). CONCLUSIONS Half of adolescents after RYGB reported sufficient long-term adherence to supplementation. Adhering to supplements and reporting a higher micronutrient intake were associated with more favorable biochemistry. Results support the recommendations for monitoring micronutrient intake and biochemistry in all patients who have undergone RYGB surgery, and the recommendation of higher preventive supplementation of vitamin D and iron in both sexes. As hypothesized, adolescents not adhering had a higher prevalence of long-term micronutrient deficiencies.

Abstract
BACKGROUND Bariatric surgery results in weight loss and health improvements in adults and adolescents. However, whether outcomes differ according to the age of the patient at the time of surgery is unclear. METHODS We evaluated the health effects of Roux-en-Y gastric bypass in a cohort of adolescents (161 patients enrolled from 2006 through 2012) and a cohort of adults (396 patients enrolled from 2006 through 2009). The two cohorts were participants in two related but independent studies. Linear mixed and Poisson mixed models were used to compare outcomes with regard to weight and coexisting conditions between the cohorts 5 years after surgery. The rates of death and subsequent abdominal operations and selected micronutrient levels (up to 2 years after surgery) were also compared between the cohorts. RESULTS There was no significant difference in percent weight change between adolescents (-26%; 95% confidence interval [CI], -29 to -23) and adults (-29%; 95% CI, -31 to -27) 5 years after surgery (P = 0.08). After surgery, adolescents were significantly more likely than adults to have remission of type 2 diabetes (86% vs. 53%; risk ratio, 1.27; 95% CI, 1.03 to 1.57) and of hypertension (68% vs. 41%; risk ratio, 1.51; 95% CI, 1.21 to 1.88). Three adolescents (1.9%) and seven adults (1.8%) died in the 5 years after surgery. The rate of abdominal reoperations was significantly higher among adolescents than among adults (19 vs. 10 reoperations per 500 person-years, P = 0.003). More adolescents than adults had low ferritin levels (72 of 132 patients [48%] vs. 54 of 179 patients [29%], P = 0.004). CONCLUSIONS Adolescents and adults who underwent gastric bypass had marked weight loss that was similar in magnitude 5 years after surgery. Adolescents had remission of diabetes and hypertension more often than adults.

Abstract
Objective This study was conducted to evaluate the taste and grittiness of two formulations of Riomet® ER (metformin hydrochloride for extended release [ER] oral suspension 100 mg/mL) differing only in their flavoring agents (strawberry and grape) in comparison with two commercially available immediate-release (IR) formulations of metformin, Riomet® Cherry (metformin hydrochloride oral solution 500 mg/5 mL) and metformin IR tablets (metformin hydrochloride IR tablets 500 mg), in healthy human subjects aged 10–70 years. Methods Five comparison sets (i.e., Riomet® Cherry vs. Riomet® ER Strawberry; Riomet® Cherry vs. Riomet® ER Grape; metformin IR vs. Riomet® ER Strawberry; metformin IR vs. Riomet® ER Grape; and Riomet® Cherry vs. metformin IR) were evaluated. Riomet® ER was reconstituted as instructed on the label. Metformin IR tablets were crushed one at a time into a fine powder using a pharmaceutical pill crusher and mixed with 5 mL of water. A 2.5-mL dose of each product was administered to each subject. Subjects were instructed not to swallow any of the products. Each product in the comparison set was rated by the subjects for taste and grittiness according to a 7-point hedonic facial scale and a 5-point level of agreement scale. A comparison questionnaire was also completed by the subjects after evaluating each set. In all, 56 subjects were enrolled and 55 subjects completed the study. The taste preference was statistically evaluated. Results and Conclusions All Riomet® formulations were significantly preferred overall to metformin IR crushed tablets. Both the strawberry and the grape flavors of Riomet® ER tended to be preferred to Riomet® Cherry.

Abstract
The study purpose was to describe dietary intake and the factors influencing micronutrient supplements (MS) use in Celiac Disease (CD) ± Type 1 Diabetes (T1D). Three-day food records collected from parents of youth (3-18 years) with CD (n = 14) ± T1D (n = 10) were assessed for macro and micronutrient intake, diet quality (DQ), glycemic index (GI), glycemic load (GL), and food group intake. Focus group methodology and thematic concept analysis were conducted to determine factors influencing adolescent MS use. Mean ± SD age was 11 ± 4.4 (CD) and 13 ± 3.7 (CD + T1D) (P = 0.32). Body mass index was within healthy reference ranges (17.9 ± 2.5 [CD]; 19.3 ± 3.8 [CD + T1D] kg/m2; P = 0.61). The majority of youth with CD ± T1D (>90%) had high intakes of sugar and saturated fat, had high GI and GL, and met food serving recommendations and DQs that were indicative of "needs improvement." With the exception of vitamin D, vitamin E, folate, calcium, and potassium, youth in both groups met the estimated average requirements (EAR) for most micronutrients. MS use corrected suboptimal vitamin D intake; however, vitamin E, folate, calcium, and potassium intake remained below the EAR. Variables influencing adolescent MS use included daily routine, health professional influence, disease management (CD + T1D), and lack of knowledge about the need for MS. Strategies to elicit adolescent MS use varied between parent and adolescents.

Abstract
The American Society for Metabolic and Bariatric Surgery Pediatric Committee updated their evidence-based guidelines published in 2012, performing a comprehensive literature search (2009-2017) with 1387 articles and other supporting evidence through February 2018. The significant increase in data supporting the use of metabolic and bariatric surgery (MBS) in adolescents since 2012 strengthens these guidelines from prior reports. Obesity is recognized as a disease; treatment of severe obesity requires a life-long multidisciplinary approach with combinations of lifestyle changes, nutrition, medications, and MBS. We recommend using modern definitions of severe obesity in children with the Centers for Disease Control and Prevention age- and sex-matched growth charts defining class II obesity as 120% of the 95th percentile and class III obesity as 140% of the 95th percentile. Adolescents with class II obesity and a co-morbidity (listed in the guidelines), or with class III obesity should be considered for MBS. Adolescents with cognitive disabilities, a history of mental illness or eating disorders that are treated, immature bone growth, or low Tanner stage should not be denied treatment. MBS is safe and effective in adolescents; given the higher risk of adult obesity that develops in childhood, MBS should not be withheld from adolescents when severe co-morbidities, such as depressed health-related quality of life score, type 2 diabetes, obstructive sleep apnea, and nonalcoholic steatohepatitis exist. Early intervention can reduce the risk of persistent obesity as well as end organ damage from long standing co-morbidities.

Abstract
BACKGROUND A growing number of studies suggest that bariatric surgery is safe and effective for adolescents with severe obesity. However, surprisingly little is known about changes in dietary intake and eating behavior of adolescents who undergo bariatric surgery. OBJECTIVE Investigate changes in dietary intake and eating behavior of adolescents with obesity who underwent bariatric surgery (n = 119) or lifestyle modification (LM) (n = 169). SETTING University-based health systems METHODS: A prospective investigation of 288 participants (219 female and 69 male) prior to bariatric surgery or LM and again 6, 12, and 24 months (surgery patients only) after treatment. Measures included changes in weight, macronutrient intake, eating behavior, and relevant demographic and physiological variables. RESULTS Adolescents who underwent bariatric surgery experienced significantly greater weight loss than those who received LM. The two groups differed in self-reported intake of a number of macronutrients at 6 and 12 months from baseline, but not total caloric intake. Patients treated with surgery, compared to those treated with LM, also reported significantly greater reductions in a number of disordered eating symptoms. After bariatric surgery, greater weight loss from postoperative month 6 to 12 was associated with self-reported weight consciousness, craving for sweets, and consumption of zinc. CONCLUSIONS Adolescents who underwent bariatric surgery, compared to those who received LM, reported significantly greater reductions in weight after 1 year. They also reported greater reductions in disordered eating symptoms. These findings provide new information on changes in dietary intake and eating behavior among adolescents who undergo bariatric surgery.

Abstract
After bariatric surgery, rates of adherence to behavioral recommendations, including attending regular appointments and following specific dietary, physical activity, and vitamin use recommendations, tend to be highly variable across studies. Lack of consistency in measurement of adherence is a likely contributor to this variability, making it challenging to determine the prevalence and impact of nonadherence in this population. PubMed was searched for articles measuring behavioral adherence or compliance in patients after bariatric surgery, resulting in 85 articles. Articles were reviewed for the definition and measurement of adherence in each area (appointment attendance, as well as dietary, physical activity, and vitamin use adherence), and on the use and reporting of recommended adherence measurement strategies. Over half of the articles measured adherence to appointment attendance. Significant variability was found across adherence definitions and measurement methods, and use of recommended adherence measurement strategies was poor. Adherence was mostly commonly measured via self-report (either verbal or written) using cutoffs for adherent versus nonadherent behavior. Over half of studies assessed adherence up to ≥2 years postsurgery. Recommendations for ways to improve adherence measurement in patients who have had bariatric surgery are outlined.

Abstract
INTRODUCTION As medication adherence continues to be a prevalent issue in today's society, the methods used to monitor medication-taking behaviors are constantly being re-evaluated and compared in search of the 'gold standard' measure. Our review aimed to assess the current literature surrounding the correlation between self-reported questionnaires (SRQs) and electronic monitoring devices to determine if these measures produce similar results. METHODS We performed a literature search from 2009 to 2017 using PubMed, PubMed In-Process and Non-Indexed, EMBASE, Ovid MEDLINE, and Ovid MEDLINE In-Process. A keyword search using the terms 'patient compliance', 'treatment compliance', 'medication adherence', 'drug monitoring', 'drug therapy', 'electronic', 'digital', 'computer', 'monitor', 'monitoring', 'drug', 'pharmaceutical preparations', 'compliance', and 'medications' was done to capture all articles. We included articles measuring adherence using both monitoring devices and SRQs. RESULTS Thirty-five articles were included in this review. The average difference in measured adherence rates between the two measures was 9.2% (range -66.3 to 61.5). A majority (62.7%) of articles reported moderate (n = 12; 27.9%), high (n = 5, 11.6%), or significant (n = 10, 23.3%) correlations between SRQs and monitoring devices. CONCLUSION Results from our review are consistent with previous studies, as we found that many of our studies produced moderate to high correlation between both SRQs and monitoring devices [Farmer, Clin Ther 21(6):1074-90 (1999), IMS Institute for Healthcare Informatics. Avoidable costs in US health care (2012), Patel et al., Respirology 18(3):546-52 (2013), Siracusa et al., J Cyst Fibros 14(5):621-6 (2015), Smith et al., Int J Cardiol 145(1):122-3 (2010)]. Our findings demonstrate that self-reported adherence produces comparable results to electronic monitoring devices. As there is not yet a 'gold standard' measure for monitoring patient adherence, SRQs and Medication Event Monitoring Systems (MEMS) operating together continue to emerge as the preferred effective method for measuring medication adherence.

Age-appropriate and acceptable paediatric dosage forms: Insights into end-user perceptions, preferences and practices from the Children's Acceptability of Oral Formulations (CALF) Study. Int J Pharm 2017; 514:296-307.

Abstract
A lack of evidence to guide the design of age-appropriate and acceptable dosage forms has been a longstanding knowledge gap in paediatric formulation development. The Children's Acceptability of Oral Formulations (CALF) study captured end-user perceptions and practices with a focus on solid oral dosage forms, namely tablets, capsules, chewables, orodispersibles, multiparticulates (administered with food) and mini-tablets (administered directly into the mouth). A rigorous development and testing phase produced age-adapted questionnaires as measurement tools with strong evidence of validity and reliability. Overall, 590 school children and adolescents, and 428 adult caregivers were surveyed across hospitals and various community settings. Attitudes towards dosage forms primarily differed based on age and prior use. Positive attitudes to tablets and capsules increased with age until around 14 years. Preference was seen for chewable and orodispersible preparations across ages, while multiparticulates were seemingly less favourable. Overall, 59.6% of school children reported willingness to take 10mm diameter tablets, although only 32.1% of caregivers perceived this size to be suitable. While not to be taken as prescriptive guidance, the results of this study provide some evidence towards rational dosage form design, as well as methodological approaches to help design tools for further evaluation of acceptability within paediatric studies.

Abstract
BACKGROUND Little is known about the long-term outcomes of bariatric surgery for severe adolescent obesity, raising questions about the durability of early responses to surgery. We aimed to analyse long-term (>5 years) outcomes of Roux-en-Y gastric bypass in a cohort of young adults who had undergone the operation during adolescence, in the Follow-up of Adolescent Bariatric Surgery at 5 Plus Years (FABS-5+) extension study. METHODS A cohort of young people aged 13-21 years underwent Roux-en-Y gastric bypass for clinically severe obesity at a paediatric academic medical centre in the USA. We did a prospective follow-up analysis of these patients' outcomes 5-12 years after surgery. Outcomes assessed included BMI, comorbidities, micronutrient status, safety, and other risks. The FABS study is registered with ClinicalTrials.gov, number NCT00776776. FINDINGS Between May, 2001, and February, 2007, 74 young people underwent Roux-en-Y gastric bypass in the FABS study. Of these, 58 individuals were eligible for the FABS-5+ study, could be located, and agreed to follow-up assessment. At baseline, the mean age of the cohort was 17·1 years (SD 1·7) and mean BMI was 58·5 kg/m2 (10·5). At mean follow-up of 8·0 years (SD 1·6; range 5·4-12·5), the mean age of the cohort was 25·1 years (2·4) and mean BMI was 41·7 kg/m2 (12·0; mean change in BMI -29·2% [13·7]). From baseline to long-term follow-up, significant declines were recorded in the prevalence of elevated blood pressure (27/57 [47%] vs 9/55 [16%]; p=0·001), dyslipidaemia (48/56 [86%] vs 21/55 [38%]; p<0·0001), and type 2 diabetes (9/56 [16%] vs 1/55 [2%]; p=0·03). At follow-up, 25 (46%) of 58 patients had mild anaemia (ie, not requiring intervention), 22 (45%) had hyperparathyroidism, and eight (16%) had low amounts of vitamin B12 (ie, below the normal cutpoint). INTERPRETATION Roux-en-Y gastric bypass surgery resulted in substantial and durable bodyweight reduction and cardiometabolic benefits for young adults. Long-term health maintenance after Roux-en-Y gastric bypass should focus on adherence to dietary supplements and screening and management of micronutrient deficiencies.

Comparison of self-report and electronic monitoring of 6MP intake in childhood ALL: a Children's Oncology Group study. Blood 2017; 129:1919-1926. [PMID: 28153823 DOI: 10.1182/blood-2016-07-726893] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Accepted: 12/29/2016] [Indexed: 01/02/2023] Open
Abstract
Adequate exposure to oral 6-mercaptopurine (6MP) during maintenance therapy for childhood acute lymphoblastic leukemia (ALL) is critical for sustaining durable remissions; accuracy of self-reported 6MP intake is unknown. We aimed to directly compare self-report to electronic monitoring (Medication Event Monitoring System [MEMS]) and identify predictors of overreporting in a cohort of 416 children with ALL in first remission over 4 study months (1344 patient-months for the cohort) during maintenance therapy. Patients were classified as "perfect reporters" (self-report agreed with MEMS), "overreporters" (self-report was higher than MEMS by ≥5 days/month for ≥50% of study months), and "others" (not meeting criteria for perfect reporter or overreporter). Multivariable logistic regression examined sociodemographic and clinical characteristics, 6MP dose intensity, TPMT genotype, thioguanine nucleotide levels, and 6MP nonadherence (MEMS-based adherence <95%) associated with the overreporter phenotype; generalized estimating equations compared 6MP intake by self-report and MEMS. Self-reported 6MP intake exceeded MEMS at least some of the time in 84% of patients. Fifty patients (12%) were classified as perfect reporters, 98 (23.6%) as overreporters, 2 (0.5%) as underreporters, and 266 (63.9%) as others. In multivariable analysis, the following variables were associated with the overreporter phenotype: non-white race: Hispanic, odds ratio (OR), 2.4, P = .02; Asian, OR, 3.1, P = .02; African American, P < .001; paternal education less than college (OR, 1.4, P = .05); and 6MP nonadherence (OR, 9.4, P < .001). Self-report of 6MP intake in childhood ALL overestimates true intake, particularly in nonadherent patients, and should be used with caution.

Abstract
Roughly 1% of all weight loss surgery is performed in adolescents. There is strong evidence demonstrating significant postsurgical weight loss, improvement in quality of life, and reduction in comorbidities such as hypertension and diabetes. Reports of postoperative complications in adolescents are few because of the small sample size in most series. Despite vitamin supplementation, nutritional deficiencies requiring hospitalization occur occasionally after Roux-en-Y gastric bypass. Wernicke encephalopathy, a triad of ophthalmoplegia, ataxia, and altered mental status, is a serious consequence of thiamine (vitamin B1) deficiency. Few cases of Wernicke encephalopathy after weight loss surgery have been reported in the literature and even fewer in the pediatric population. Here we describe a teenage girl who develops vomiting after Roux-en-Y gastric bypass and presented with nystagmus, irritability, and ataxia. The clinical presentation, diagnosis, and treatment of Wernicke encephalopathy in adolescents after bariatric surgery are discussed.
