Liu Z, Wang H, Fan D, Xu T, Wan F, Xia Q. Asia's Growing Contribution to Obesity Surgery Research: A 40-year Bibliometric Analysis. Obes Surg 2024; 34:2139-2153. [PMID: 38448708 PMCID: PMC11127875 DOI: 10.1007/s11695-024-07138-z] [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: 12/16/2023] [Revised: 02/25/2024] [Accepted: 02/26/2024] [Indexed: 03/08/2024]
Abstract
Bariatric metabolic surgery's global research interest is growing, particularly in Asia due to its high obesity rates. This study focuses on Asia, especially China, analyzing 3904 publications (1221 from China) from 1980 to 2022. Research output accelerated until the COVID-19 pandemic, driven by economic growth and rising obesity rates. China led contributions from 2010, but Western Asia led when adjusted for population. An intra-regional research collaboration network emerged, driven by geographic proximity and similar economic environments. Keyword analysis highlighted emerging topics like "laparoscopic sleeve gastrectomy" and "non-alcoholic fatty liver disease," indicating a shift in focus. The study recommends disseminating research in top-tier journals to enhance visibility and impact.

Abstract
BACKGROUND To identify the implications of bariatric surgery on the oral health of patients with morbid obesity. METHODS Two reviewers independently performed a search of the electronic databases: MedLine, PubMed, SciELO, LILACS, and Scopus, for clinical trials in humans and cohort studies. The search strategy used was Bariatric Surgery and Oral Health or Mouth Disease and Humans and Periodontitis. A total of 26 articles were obtained, and after title screening and full reading, 8 articles were included in this review. RESULTS Increased food intake at shorter intervals and increased frequency of regurgitation in these patients were associated with the increased development of dental caries, dental erosion, and increased salivary flow rate. CONCLUSION Intense oral control is recommended for the prevention and early treatment of these conditions and to avoid nonsystemic effects in these patients.

Abstract
Recent reports have shown an association between obesity and periodontitis, but the precise relationship between these conditions has yet to be clarified. The purpose of this study was to compare the status of periodontitis, tooth loss, and obesity. Participants comprised 235 patients at the Center for Medical and Dental Collaboration in Kanagawa Dental University Hospital between 2018 and 2020. Clinical examinations such as blood testing, body composition analysis, periodontal measurement, assessment of chewing ability, salivary testing, and oral malodor analysis were performed. Periodontal inflamed surface area (PISA) was significantly associated with the number of teeth and body mass index (BMI). The number of teeth was negatively associated with age, but positively with chewing ability. Chewing ability was associated negatively with age, and positively with high-sensitivity C-reactive protein (hsCRP). The level of methyl-mercaptan in breath and protein and leukocyte scores from salivary testing were positively associated with PISA. The rate of insufficient chewing ability was increased in subjects with hemoglobin (Hb)A1c ≥ 7%. The high PISA group showed increased hsCRP. BMI as an obesity marker was positively associated with PISA, indicating periodontal inflammation. Chewing ability was related to serum markers such as HbA1c and hsCRP.

Abstract
AIMS To evaluate inter- and intrarater reliability of unidigital and bidigital vaginal palpation of pelvic floor muscle (PFM) maximal voluntary contraction (MVC) according to PFM risk factors and dysfunctions. METHODS A total of 187 women were recruited and evaluated by two examiners. Both performed the evaluation of MVC with unidigital and bidigital palpation, graded by Modified Oxford Scale. After 7-10 days, one examiner repeated the assessment. To analyze reliability by Cohen's linear Kappa (κw), participants were allocated into different groups according to: body mass index (BMI), menopause, parity, type of delivery and PFM dysfunctions, as pelvic organ prolapse (POP), constipation, urgency, urgency urinary incontinence, pelvic pain, and stress urinary incontinence. RESULTS Inter-rater reliability of unidigital palpation was considered fair (κw = 0.21-0.40) to moderate (κw = 0.41-0.60) according to BMI, postmenopausal status, parity, type of delivery, and PFM dysfunctions. Inter-rater reliability of bidigital palpation varied from none (κw = 0.00-0.20) to moderate for all risk factors and PFM dysfunctions. Intra-rater reliability of unidigital palpation was considered fair only for women with POP (κw = 0.37) and moderate to substantial (κw = 0.61-0.80) to all other variables. Intra-rater reliability of bidigital palpation ranged from moderate to almost perfect (κw = 0.81-1.00). CONCLUSIONS When performing vaginal palpation, physiotherapists must consider the way that is performing the evaluation, as some PFM risk factors and dysfunctions could influence the inter- and intrarater reliability of unidigital and bidigital palpation.

Abstract
Obesity is an increasing problem of the 21st century. A frequent intervention is bariatric surgery. The impact of bariatric surgery on oral health is largely unknown. The aim of the present case-control study was to survey the perceived oral health amongst individuals that had undergone bariatric surgery and compare the measures with two cohorts consisting of healthy individuals with respectively at or below versus above a body mass index score of 30. Study volunteers were recruited from interest group on the Internet. The study participants completed online a validated oral health-related quality of life scale, that is, OHIP-S. The three cohorts consisted of individuals that had undergone bariatric surgery (OS, n = 77) and the healthy obese (ONS, n = 45) and nonobese individuals (HNS, n = 71). Nonparametric Kruskal-Wallis rank sum tests were used to estimate likelihood of nondifference amongst the three cohorts. Individuals that had undergone bariatric surgery reported significant more oral health problems than the study participants in with the two other cohorts. Their perception of oral health-related quality of life was higher or similar to the obese study participants and lower than for nonobese study participants. Perceived oral health problems appear to be more frequent amongst individuals that have undergone bariatric surgery in comparison with healthy obese and nonobese individuals. Bariatric surgery may be consider a risk marker for impaired oral health.

Abstract
PURPOSE Factors associated with increased intra-abdominal pressure such as chronic cough, morbid obesity, and constipation may be related to pelvic floor dysfunction. In this study, we compared anorectal manometry values and clinical data of class II and III morbidly obese patients referred to bariatric surgery with that of non-obese patients. METHODS We performed a case-matched study between obese patients referred to bariatric surgery and non-obese patients without anorectal complaints. The groups were matched by age and gender. Men and nulliparous women with no history of abdominal or anorectal surgery were included in the study. Anorectal manometry was performed by the stationary technique, and clinical evaluation was based on validated questionnaires. RESULTS Mean age was 44.8 ± 12.5 years (mean ± SD) in the obese group and 44.1 ± 11.8 years in the non-obese group (p = 0.829). In the obese group, 65.4% of patients had some degree of fecal incontinence. Mean squeeze pressure was significantly lower in obese than in non-obese patients (155.6 ± 64.1 vs. 210.1 ± 75.9 mmHg, p = 0.004), and there was no significant difference regarding mean rest pressure in obese patients compared to non-obese ones (63.7 ± 23.1 vs. 74.1 ± 21.8 mmHg, p = 0.051). There were no significant differences in anorectal manometry values between continent and incontinent obese patients. CONCLUSIONS The prevalence of fecal incontinence among obese patients was high regardless of age, gender, and body mass index. Anal squeeze pressure was significantly lower in obese patients compared to non-obese controls.

Abstract
The aim of this study was to evaluate the outcomes after laparoscopic sleeve gastrectomy (SG) in a VA population.SG has recently gained popularity as a definitive bariatric surgery procedure. Data are lacking on long-term outcomes, particularly in a Veterans Affairs population.We retrospectively reviewed 223 patients who underwent SG for morbid obesity between January 2009 and June 2014. Data on length of stay, complications, interval weight loss, comorbidities, and number of therapies preoperatively and at long-term follow-up were collected.There were 164 males and 59 females who underwent SG. The mean body mass index was 45.4 kg/m. Mean excess weight loss at 1 year was 62.9%, and 47.0% at 5 years. Weight loss continued until 12 to 18 months, when there was a nadir in weight loss (P < .001). There were 4 deaths and 4 staple-line leaks, with 3 deaths related to late cardiac events. One early death occurred in a very high-risk patient. All staple-line leaks were managed nonoperatively. Of the 223 patients, 193 had hypertension, 137 diabetes, 158 hyperlipidemia, 119 obstructive sleep apnea (OSA), and 125 had gastroesophageal reflux disease. Preoperatively, patients were on a mean of 1.9 antihypertensive and 0.9 hyperlipidemic, anti-reflux and oral hypoglycemic agents. Fifty percent of patients with diabetes were on insulin and 68% with OSA used continuous positive airway pressure/bilevel positive airway pressure (CPAP/BiPAP). We found significant absolute reductions in mean antihypertensive medications (-0.8), hyperlipidemic agents (-0.4), antireflux agents (-0.4), oral hypoglycemics (-0.6), insulin use (-25%), and use of CPAP/BiPAP (-55%) (all P < .001).Laparoscopic sleeve gastrectomy is a safe and effective bariatric surgery procedure, resulting in significant early weight loss up to 18 months and long-term improvement in all major obesity-related comorbid conditions.

Abstract
PURPOSE We aimed to evaluate obesity, a risk factor of metabolic syndrome, and its association with prostatic enlargement in a retrospective cohort in Korea. METHODS Baseline data were obtained from the Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population (KoGES-ARIRANG). Between March 2015 and November 2015, 2,127 male participants of KoGES-ARIRANG were invited to the Korean Prostate Health Council Screening Program, and 602 participants underwent urological examination, including serum prostate specific antigen measurement and transrectal ultrasonography, and completed the International Prostate Symptom Score questionnaire. The data for 571 participants were analyzed, after excluding 31 men who had a history of prostatic disease or testosterone replacement, or had undergone a prior prostatic surgery or procedure. RESULTS Among components of metabolic syndrome, waist circumference had a statistically significant linear correlation with incremental increases in prostate volume (B=0.181, P=0.004). Abdominal obesity as determined by anthropometric measures including body mass index (odds ratio [OR], 1.205; 95% confidence interval [CI], 1.088-1.336), waist circumference (OR, 1.073; 95% CI, 1.032-1.115), body fat (OR, 1.126; 95% CI, 1.056-1.202), and visceral fat composition (OR, 1.667; 95% CI, 1.246-2.232) was significantly associated with the presence of high-volume benign prostatic hyperplasia (BPH) (prostate volume≥ 40 mL). Furthermore, the highest quartile of serum leptin (OR, 3.541; 95% CI, 1.103-11.365) and adiponectin levels (OR, 0.315; 95% CI, 0.102-0.971) were significantly correlated with high-volume BPH compared to the lowest quartile of levels. CONCLUSIONS Abdominal obesity and serum leptin level are positively associated with prostate growth, whereas serum adiponectin level is inversely associated with the presence of prostatic enlargement.

Abstract
Diabetes mellitus and obesity are closely interrelated and pose a major burden on health care in terms of morbidity and mortality. Weight loss has favorable metabolic benefits for glycemic control and improvement of metabolic syndrome. Bariatric surgery (BS) is the most effective treatment for weight loss with durable results as compared to lifestyle modification. BS procedures have been associated with significant reduction in abdominal obesity, metabolic syndrome components, and glycemic control requiring fewer medications. Long-term risks of surgery include nutritional deficiencies, osteoporosis, bone fractures, and hyperinsulinemic hypoglycemia, which need to be carefully balanced with metabolic benefits for individual patients.

Abstract
PURPOSE Examine the relationship between intraocular pressure (IOP) and body mass index (BMI) in the seated and supine positions. PATIENTS AND METHODS A prospective observational study was conducted in which the IOP was measured with a Tono-Pen (Reichert Inc., Depew, NY) in seated and supine positions in eligible participants with a wide range of BMI (18 to 70 kg/m). The paired t test was used to compare seated to supine IOP. Stepwise regression analyses were used to investigate the correlation between IOP and BMI at these positions after adjusting for confounding variables of increased IOP, including age, race, mean arterial blood pressure, and central corneal thickness (μm). RESULTS The mean sitting IOP (16.3±2.9 mm Hg) was statistically lower than the mean supine IOP (17.7±3.1 mm Hg; P<0.0001). For each 10 unit increase in BMI, there was an increase of 0.55±0.23 mm Hg (P=0.0184) in IOP in the seated position and an increase of 0.49±0.24 mm Hg in IOP in the supine position (P=0.0409). BMI did not have a significant effect on the amount of increase in IOP observed in changing from the seated to supine position. CONCLUSIONS Higher BMI is correlated with higher IOP in both the seated and supine positions. However, BMI has no significant effect on the amount of increase in IOP observed in changing from the seated to supine position.

Abstract
Obesity is a major and growing health care concern. Large epidemiologic studies that evaluated the relationship between obesity and mortality, observed that a higher body-mass index (BMI) is associated with increased rate of death from several causes, among them cardiovascular disease; which is particularly true for those with morbid obesity. Being overweight was also associated with decreased survival in several studies. Unfortunately, obese subjects are often exposed to public disapproval because of their fatness which significantly affects their psychosocial behavior. All obese patients (BMI ≥ 30 kg/m2) should receive counseling on diet, lifestyle, exercise and goals for weight management. Individuals with BMI ≥ 40 kg/m2 and those with BMI > 35 kg/m2 with obesity-related comorbidities; who failed diet, exercise, and drug therapy, should be considered for bariatric surgery. In current review article, we will shed light on important medical principles that each surgeon/gastroenterologist needs to know about bariatric surgical procedure, with special concern to the early post operative period. Additionally, we will explain the common complications that usually follow bariatric surgery and elucidate medical guidelines in their management. For the first 24 h after the bariatric surgery, the postoperative priorities include pain management, leakage, nausea and vomiting, intravenous fluid management, pulmonary hygiene, and ambulation. Patients maintain a low calorie liquid diet for the first few postoperative days that is gradually changed to soft solid food diet within two or three weeks following the bariatric surgery. Later, patients should be monitored for postoperative complications. Hypertension, diabetes, dumping syndrome, gastrointestinal and psychosomatic disorders are among the most important medical conditions discussed in this review.

Abstract
The scope of this study was to conduct a systematic review of the studies on the association between obesity and periodontitis. The methods applied included a literature search strategy and selection of studies using inclusion and exclusion in accordance with the criteria for characteristics of the studies and meta-analysis. The research was conducted in the PubMed, Embase and Lilacs databases through 2010. Selected papers were on studies on humans investigating whether or not obesity is a risk factor for periodontitis. Of the 822 studies identified, 31 studies met the inclusion criteria and were included in this meta-analysis. The risk of periodontitis was associated with obesity (or had a tendency for this) in 25 studies, though it was not associated in 6 studies. The meta-analysis showed a significant association with obesity and periodontitis (OR = 1.30 [95% Confidence Interval (CI), 1.25 - 1.35]) and with mean Body Mass Index (BMI) and periodontal disease (mean difference = 2.75). Obesity was associated with periodontitis, however the risk factors that aggravate these diseases should be better clarified to elucidate the direction of this association. Working with paired samples and avoiding confusion factors may contribute to homogeneity between the studies.

Abstract
OBJECTIVES We evaluate oral health conditions before and after bariatric surgery. METHODS The sample was composed of 59 patients who had undergone Roux-en-Y gastric bypass (RYGB). Salivary flow, periodontal pocket depth and dental wear were evaluated before and after 6 months of surgery. Body mass index (BMI), C-reactive protein (CRP) and glucose levels were obtained from the patient's medical files. A t-test was used for dependent samples. RESULTS The mean BMI decreased from 49.31 ± 8.76 to 35.52 ± 8.12 kg/m(2) in 6 months after surgery (P < 0.000). Before surgery, 67% of patients had high levels of CRP and 38% higher blood glucose levels and after surgery there were significant reductions in these levels (P < 0.001). Salivary flow ranged from 0.84 to 0.95 ml/min. There was increased prevalence of periodontal pockets (P = 0.022) and mean pocket depth increased to about 0.5 mm (P < 0.001). The percentage of surfaces with dental wear in dentine was significantly higher after bariatric surgery (P = 0.002), while dental wear in enamel decreased (P = 0.019). CONCLUSIONS Bariatric surgery may improve systemic conditions. However, it had a negative impact on oral health conditions because of an increase in periodontal disease and dental wear.

Abstract
Pelvic floor disorders are very frequent among women. Weight loss can help them to achieve urinary and faecal continence again. In this narrative review, the possible mechanisms of pelvic floor disorders in obese women, their symptoms and the role of bariatric surgery in changing their quality of life are presented. We retrieved the included results of our study after performing a systematic, electronic search in PubMed (December 17, 2012) and Scopus (December 17, 2012). The main mechanism causing the development of pelvic floor disorders is chronically increased abdominal pressure as it overts structural damage or neurologic dysfunction predisposing to prolapse and incontinence. The symptoms include a sensation of vaginal fullness or pressure, uterine descent, sacral back pain with standing, vaginal spotting from ulceration of the protruding cervix or vagina, coital difficulty, lower abdominal discomfort, and voiding and defecatory difficulties. Evidence indicates that massive weight loss (45 to 50 kg) improves incontinence in morbidly obese women after bariatic surgery. Faecal incontinence is also improved after bariatric surgery. This review highlights the role of bariatric surgery in weight reduction of obese women that could act as a treatment for the pelvic floor disorders faced by those women offering improvement in incontinence as well as quality of life.

Abstract
The prevalence of obesity has increased so rapidly over the last few decades that it is now considered a global epidemic. Obesity, defined as a body mass index (BMI) of 30 or more, is associated with several comorbid conditions that decrease life expectancy and increase health care costs. Diet therapies have been reported to be ineffective in the long-term treatment of obesity, and guidelines for the surgical therapy of morbid obesity (BMI ≥ 40 or BMI ≥ 35 in the presence of substantial comorbidities) have since been established. Considering the number of bariatric surgical procedures has dramatically increased since these guidelines were established, we review the types of bariatric surgical procedures and their impact on diabetes, sleep apnea, dyslipidemia and hypertension - 4 major obesity-related comorbidities.

Abstract
INTRODUCTION Morbid obesity control can be done by bariatric surgery that restricts or reduces the amount of food absorption. The objective of this review was to identify the consequences of bariatric surgery and its repercussions on oral health. METHOD It was used the Virtual Library of Health, which included articles that had any direct or indirect connection between bariatric surgery and oral health, and published in the last ten years. RESULTS Some complications of the surgery are chronicle reflux and nutritional deficiency, which may bring repercussions on the oral cavity, such as tooth erosion, bone loss and dental caries. On the other hand, there are also positive impacts, such as the decrease of diabetes, apnea and improvement on self-esteem, that makes the patients less vulnerable to complications regarding oral health, for example xerostomy and periodontal disease. CONCLUSION Maintaining proper oral health in patients undergoing bariatric surgery contributes to success after surgery protecting benefits and minimizing side effects.

Abstract
RACIONAL: A incontinência urinária é bem documentada como comorbidade da obesidade. Estudos demonstram resolução ou atenuação da incontinência após a perda de peso. Porém, os mecanismos pelos quais isso ocorre ainda não estão claros. OBJETIVO: Avaliar os efeitos da cirurgia bariátrica na função do assoalho pélvico em mulheres. MÉTODOS: Foram avaliadas 30 mulheres que estavam em lista de espera para realizar a operação. Foi verificada a prevalência de incontinência urinária no pré e no pós-operatório e seu impacto na qualidade de vida através do King's Health Questionnaire. A qualidade da contração muscular do assoalho pélvico foi avaliada através da Escala de Oxford Modificada e da perineometria. RESULTADOS: Vinte e quatro mulheres finalizaram o estudo. O índice de massa corporal passou de 46,96±5,77 kg/m2 no pré-operatório para 29,97±3,48 kg/m2 no pós-operatório, e a perda percentual do excesso de peso média foi de 70,77±13,26%. A prevalência de incontinência urinária passou de 70,8% no pré-operatório para 20,8% no pós-operatório. Após um ano da cirurgia bariátrica, houve redução do impacto da incontinência urinária na qualidade de vida em sete dos nove domínios avaliados no questionário. A mediana da Escala de Oxford Modificada aumentou de três no pré-operatório para quatro no pós-operatório. A perineometria apresentou aumento significativo na média das três contrações solicitadas, passou de 21,32±12,80 sauers para 28,83±16,17 sauers na comparação pré e pós-operatória. O pico de contração também aumentou significativamente no pós-operatório em relação ao pré-operatório, passou de 25,29±14,49 sauers para 30,92±16,20 sauers. CONCLUSÃO: A perda massiva de peso através da cirurgia bariátrica repercute positivamente na função do assoalho pélvico e na qualidade de vida das mulheres com obesidade mórbida.

Abstract
To review the effects of obesity surgery on oral health and to present a case report of the periodontal condition of an obese woman who underwent bariatric surgery. A search of studies related to bariatric surgery and oral health was made in PubMed. For case report, BMI, salivary flow, and periodontal condition were evaluated during three different periods. The oral health problems found were dental wear, periodontal diseases, xerostomia, and dental caries. The patient who was evaluated before bariatric surgery and was followed up for 2 years, lost 40.4 kg, presented normal blood glucose levels and controlled hypertension without medication. Salivary flow remained of equal value in the first year, there was an increase in mean probing depth and there existed low bone density in these sites. Patients who have undergone bariatric surgery need to be closely monitored after surgery to prevent the development of oral complications, especially periodontal conditions.

Abstract
Object
The purpose of this study was to review the literature on the effectiveness of bariatric surgery for obese patients with idiopathic intracranial hypertension (IIH) with regard to both symptom resolution and resolution of visual deficits.
Methods
The published literature was reviewed using manual and electronic search techniques. Data from each relevant manuscript were gathered, analyzed, and compared. These included demographic data, pre- and postoperative symptoms, pre- and postoperative visual field deficits, bariatric procedure type, absolute weight loss, changes in body mass index, and changes in CSF opening pressure.
Results
Eleven relevant publications (including 6 individual case reports) were found, reporting on a total of 62 patients. The Roux-en-Y gastric bypass was the most common bariatric procedure performed. Fifty-six (92%) of 61 patients with recorded postoperative clinical history had resolution of their presenting IIH symptoms following bariatric surgery. Thirty-four (97%) of 35 patients who had undergone pre- and postoperative funduscopy were found to have resolution of papilledema postoperatively. Eleven (92%) of 12 patients who had undergone pre- and postoperative formal visual field testing had complete or nearly complete resolution of visual field deficits, and the remaining patient had stabilization of previously progressive vision loss. In 13 patients both pre- and postoperative CSF pressures were recorded, with an average postoperative pressure decrease of 254 mm H2O. Changes in weight loss and body mass index varied depending on the reported postoperative follow-up interval.
Conclusions
The published Class IV evidence suggests that bariatric surgery may be an effective treatment for IIH in obese patients, both in terms of symptom resolution and visual outcome. Prospective, controlled studies are necessary for better elucidation of its role.

Abstract
Obesity has adverse consequences in the general population. In patients with chronic kidney disease (CKD), it is associated with increased inflammation, insulin resistance, hypertension and dyslipidaemia, which are important risk factors for CKD progression and death. In adults with CKD stages 1-4, weight loss should be encouraged, it reduces proteinuria and glomerular hyperfiltration, which are frequent in obese patients. Proposals for modifications of lifestyle, physical activity and calorie restriction are the first measures. Pharmacological treatments are generally unsafe in these patients, except orlistat, but that has modest efficacy. Bariatric surgery may be the only option in severe obesity, if all other measures fail. For obese patients on dialysis treatment, who are eligible for kidney transplantation, weight loss is mandatory to prevent obesity-related surgical complications and improve patient and graft survival after transplantation. Interventions should place an emphasis on exercise to increase muscle mass, and calorie but not protein restriction. Bariatric surgery should be carried out by experienced surgeons due to the high risk of complications. For obese patients who are not considered transplant candidates the benefits of weight loss remain uncertain.

Abstract
The burden of disease associated with the obesity epidemic shortens lives, and prevalence is accelerating. As with other chronic diseases, improved outcomes are associated with effective self-management of obesity across the life span. The disease of obesity, then, fits squarely within the disease management and chronic care models. This article reviews selected interventions, described in peer-reviewed literature, designed to achieve significant weight loss for individuals identified as overweight or obese. The study objective is to provide an overview of the full range of methods and models for weight loss, including some available without medical supervision. The intended audience includes individuals and organizations with an expressed interest in disease management and the chronic care models. Our review identified promising lines of investigation for future research that span diverse medical disciplines applied to obesity. The quality of the studies included in our review was uneven, and compromises the current evidence for effectiveness and efficacy. Generally, our results showed that combination approaches-surgical or pharmacologic, combined with a behavioral intervention-were most likely to be effective.

Abstract
OBJECTIVE Find conditions with significantly different prevalence among employees diagnosed with morbid obesity (DMO). Examine the effect of bariatric surgery on the prevalence of all categories of comorbid conditions after surgery. METHODS This large employer retrospective database analysis used matching to create two cohorts: Those with a DMO and those without. RESULTS The DMO cohort had higher diagnosis rates in every Agency for Healthcare Research and Quality major diagnostic category except pregnancy, and it had significantly higher prevalence in 147 of 261 Agency for Health care Research and Quality specific categories. Those electing to undergo bariatric surgery experienced significant prevalence decreases in 26 of 261 specific categories. CONCLUSION Employees DMO are at higher risk for many serious diseases. Bariatric surgery has been effective in promoting weight loss and decreasing the rates of many serious comorbidities.

Abstract
PURPOSE We reviewed the effects of obesity and long-term weight loss on nononcological urological disease, particularly urinary stone formation, erectile dysfunction, female sexual dysfunction, voiding dysfunction and urinary incontinence. MATERIALS AND METHODS A literature search was conducted using Ovid's MEDLINE, accessed through Emory University's Health Sciences Library web site. The subject headings obesity, weight loss surgery, urolithiasis, sexual dysfunction, erectile dysfunction, benign prostatic hyperplasia and urinary incontinence were used as indices for the search. Articles published earlier than 10 years before the literature review (performed in summer of 2007) were not used. RESULTS There is ample evidence to support an increased risk of urolithiasis in obese patients. However, the effects of long-term weight loss on urinary stone formation have not been studied as extensively in the literature. It is unclear whether the decreased food intake after surgical weight loss procedures may negate the associated risk of malabsorption and decrease the risk of urolithiasis in the long term. The incidence and severity of erectile dysfunction in men increase with obesity. Female sexual dysfunction also appears to be positively correlated with obesity, although the literature is less clear as to the extent to which this is true. Despite a scarcity of relevant data, preliminary evidence indicates that weight loss improves sexual function in men and women. Obesity is associated with an increased incidence of benign prostatic hyperplasia and subsequent lower urinary tract symptoms in men, as well as an increased incidence of stress urinary incontinence in women. Despite a lack of relevant data, there is preliminary evidence that stress urinary incontinence and benign prostatic hyperplasia may be reversible after weight loss. CONCLUSIONS Despite the abundant evidence that indicates a correlation between obesity and several urological diseases, there is a paucity of data regarding the effects of long-term weight loss on these conditions. However, the preliminary data indicate that the detrimental effects of obesity are reversible, and that long-term weight loss may decrease the incidence and severity of urological disease. Therefore, further research is needed to elucidate the impact of long-term surgical and medical weight loss on urolithiasis, lower urinary tract symptoms and incontinence, and sexual dysfunction.

Abstract
A 22-year-old African-American woman who has been dialysis dependent for four months due to hypertensive kidney disease is referred for kidney transplantation evaluation. Due to the recent occlusion of her left forearm arteriovenous graft, she is currently being dialyzed via a right internal jugular tunneled catheter. Her medications include methyldopa 250 mg bid, Tums 1000 mg with each meal and erythropoietin with dialysis. The patient is single without children, unemployed and lives with her 38 year old mother. She does not smoke or drink. Her review of systems is unremarkable. On physical exam, her weight is 284 pounds, height is 5 feet 2 inches and her body mass index is 51.9 kg/m2. The blood pressure is 130/80 and the cardiac and pulmonary exams are unremarkable. The surgeon feels she is otherwise a good candidate for transplantation except she must lose weight before being listed. What advice should she be given regarding weight loss?

Abstract
Dr Brazis has written a review of the literature on the clinical manifestations of idiopathic intracranial hypertension, possible associated venous hypertension and intracranial dural venous sinus abnormalities, and a brief discussion of medical and surgical therapies. The preferred terminology for this condition is idiopathic intracranial hypertension, but pseudotumour cerebri is so engrained in the literature that it stubbornly remains (1). The manuscript covers the literature well, and the information reviewed serves as an excellent reference source for interested readers. Unfortunately, Dr Brazis has noted the conflicting expert opinions regarding success, failure and complications for each of the surgical procedures, and, as a result, his summary discussion is barren of any algorithm of management, or even recommendations in approaching these difficult patients.

Abstract
BACKGROUND Pediatric obesity is a growing problem affecting the health of our youth. We sought to identify the barriers to pediatric bariatric referral at a tertiary referral center. METHODS We performed a survey of pediatricians and family practitioners at a single institution to assess their perspectives on pediatric obesity. RESULTS A total of 61 physicians completed the survey (response rate 46%). All believed pediatric obesity is a major problem, and 82.0% noted an increase in the incidence during a mean period of 15 years (range 3-25). Of the 61 physicians, 88.5% used nonoperative weight loss techniques, with only 1.8% reporting satisfactory results. However, 42.6% had referred a patient (adult or pediatric) for a bariatric procedure, of whom 84.6% were satisfied with the operative outcomes. Despite the high satisfaction with bariatric procedures, 88.5% would be unlikely or would never refer a child for a bariatric procedure, and 44.3% would be somewhat or very likely to refer an adolescent. CONCLUSION Physicians caring for children recognize the growing problem of childhood and adolescent obesity. Despite the poor outcomes with nonoperative methods and the high satisfaction with the outcomes of bariatric procedures, physicians are still reluctant to refer children and adolescents for surgical weight loss procedures.

Abstract
OBJECTIVE To review the current literature and summarize the effect of obesity on outcomes of surgical treatment of pelvic floor disorders as well as the effect of weight loss on pelvic floor disorder symptoms. DATA SOURCES Relevant sources were identified by a MEDLINE search from 1966 to 2007 using the key words obesity, pelvic floor disorders, urinary incontinence (UI), fecal incontinence, and pelvic organ prolapse (POP). References of relevant studies were hand searched. METHODS OF STUDY SELECTION Relevant human observational studies, randomized trials, and review articles were included. A total of 246 articles were identified; 20 were used in reporting and analyzing the data. Meta-analyses were performed for topics meeting the appropriate criteria. TABULATION, INTEGRATION, AND RESULTS There is good evidence that surgery for stress UI in obese women is as safe as in their nonobese counterparts, but cure rates may be lower in the obese patient. Meta-analysis revealed cure rates of 81% and 85% for the obese and nonobese groups, respectively (P<.001; odds ratio [OR] 0.576, 95% confidence interval [CI] 0.426-0.779). Combined bladder perforation rates were 1.2% in the obese and 6.6% in the nonobese (P=.015; OR 0.277, 95% CI 0.098-0.782). There is little evidence on which to base clinical decisions regarding the treatment of fecal incontinence and POP in obese women, because few comparative studies were identified addressing the outcomes of prolapse surgery in obese patients compared with healthy-weight patients. Weight loss studies indicate that both bariatric and nonsurgical weight loss lead to significant improvements in pelvic floor disorder symptoms. CONCLUSION Surgery for UI in obese women is safe, but more trials are needed to evaluate its long-term effectiveness as well as treatments for both fecal incontinence and POP. Weight loss, both surgical and nonsurgical, should be considered in the treatment of pelvic floor disorders in the obese woman.

Abstract
BACKGROUND AND PURPOSE Early physical functional changes after gastric bypass surgery (GBS) are unclear, and the relationship between these changes and health-related quality of life (HR-QOL) has not been reported. We measured distances from a 6-minute walk test (6MWT) and scores on the 36-Item Short-Form Health Survey (SF-36) before and after GBS. SUBJECTS AND METHODS Twenty-five people undergoing GBS completed the SF-36 and 6MWT presurgically and at the 3-month and 6-month follow-up visits. Ratings of perceived exertion (RPE) were measured during 6MWTs. RESULTS Presurgical walking distance (X+/-SD; 414.1+/-103.7 m) was 55%+/-14% of normative values. Distances increased significantly at 3 months (505.2+/-98.0 m) and at 6 months (551.5+/-101.2 m). Final RPEs decreased significantly, and HR-QOL improved significantly. Both physical and mental health components of the SF-36 improved significantly. Distance was inversely correlated with body mass throughout the study and positively correlated with the SF-36 Physical Component Summary change from 3 to 6 months. DISCUSSION AND CONCLUSION Improved functional capacity was associated with enhanced HR-QOL. At 6 months, walking distances remained 75% of those for age-matched peers who had normal weight.

Abstract
Surgical intervention has become an accepted therapeutic alternative for the patient with medically complicated obesity. Multiple investigators have reported significant and sustained weight loss after bariatric surgery that is associated with improvement of many weight-related medical comorbidities, and statistically significant decreased overall mortality for surgically treated as compared with medically treated subjects. Although the Roux-en-Y gastric bypass (RYGB) is considered an acceptably safe treatment, an increasing number of patients are being recognized with nephrolithiasis after this, the most common bariatric surgery currently performed. The main risk factor appears to be hyperoxaluria, although low urine volume and citrate concentrations may contribute. The incidence of these urinary risk factors among the total post-RYGB population is unknown, but may be more than previously suspected based on small pilot studies. The etiology of the hyperoxaluria is unknown, but may be related to subtle and seemingly subclinical fat malabsorption. Clearly, further study is needed, especially to define better treatment options than the standard advice for a low-fat, low-oxalate diet, and use of calcium as an oxalate binder.

Abstract
Obstructive sleep apnea is a common disorder whose prevalence is linked to an epidemic of obesity in Western society. Sleep apnea is due to recurrent episodes of upper airway obstruction during sleep that are caused by elevations in upper airway collapsibility during sleep. Collapsibility can be increased by underlying anatomic alterations and/or disturbances in upper airway neuromuscular control, both of which play key roles in the pathogenesis of obstructive sleep apnea. Obesity and particularly central adiposity are potent risk factors for sleep apnea. They can increase pharyngeal collapsibility through mechanical effects on pharyngeal soft tissues and lung volume, and through central nervous system-acting signaling proteins (adipokines) that may affect airway neuromuscular control. Specific molecular signaling pathways encode differences in the distribution and metabolic activity of adipose tissue. These differences can produce alterations in the mechanical and neural control of upper airway collapsibility, which determine sleep apnea susceptibility. Although weight loss reduces upper airway collapsibility during sleep, it is not known whether its effects are mediated primarily by improvement in upper airway mechanical properties or neuromuscular control. A variety of behavioral, pharmacologic, and surgical approaches to weight loss may be of benefit to patients with sleep apnea, through distinct effects on the mass and activity of regional adipose stores. Examining responses to specific weight loss strategies will provide critical insight into mechanisms linking obesity and sleep apnea, and will help to elucidate the humoral and molecular predictors of weight loss responses.

Abstract
BACKGROUND The authors examine the mitochondrial electron transport system (ETS) with regard to caloric restriction and body size in humans. METHODS The study population included 59 morbidly obese (MO) female subjects with mean body mass index (BMI) 49.6 +/- 1.7 and 40 age-matched previously morbidly obese patients with surgically-induced caloric restriction (SCR) and mean BMI 28.9 +/- 1.1. ETS function in the 2 study groups were made by measuring their lymphocyte mitochondrial ETS complexes I-IV activities and complex III binding kinetics. Linear regression analyses were used to analyze the interactions between ETS function and BMI, energy intake, and metabolic status. RESULTS The MO, as compared to SCR, subjects had significantly (P < 0.01) higher ETS complexes II-IV activities (complex II = 20.4 +/- 1.9 vs 15.3 +/- 1.1, complex III = 129.4 +/- 10.1 vs 72.3 +/- 4.9, complex IV = 3.1 +/- 0.3 vs 1.4 +/- 0.1 nmol/mg/min for the MO vs SCR, respectively). ETS complexes activities were positively and significantly correlated with subjects' BMI, carbohydrate caloric intake, and fasting plasma insulin levels. Michaelis-Menten kinetic analysis showed that the Km for ubiquinol-2 in complex III of MO patients was 2-fold greater than SCR values, reflecting an apparent reduction in substrate binding capacities producing a resistance to electron flow in the MO population. Caloric consumption, carbohydrate calories, insulin levels, and BMI were also each significantly (P < 0.05) and positively correlated with the Km of Complex III. CONCLUSIONS ETS function and efficiency are compromised by increasing BMI and caloric consumption in morbidly obese women, and caloric restriction may reduce the potential for excessive oxidative free radical generation via the ETS.

Abstract
BACKGROUND AND AIMS Bariatric surgery is the most effective treatment for morbid obesity. The classic procedure, jejunoileal bypass, has many complications including rapid progress of liver disease. The senior author (I.F.) has developed a modification of jejunoileal bypass, which we believe overcomes many of the shortcomings of the classic procedure. METHODS Consecutive patients referring for bariatric surgery were included. A modified jejunoileal bypass in which the defunctionalized limb is eliminated by anastomosing its ends to the gall bladder and cecum was performed. Liver biopsies were taken during operation and at a mean of 16 months later. The patients were followed for 5 years. RESULTS Forty-three patients were enrolled. The mean value of weight and body mass index (BMI) fell from 128 kg and 46 kg/m(2) before operation to 85 kg and 31 kg/m(2) at 5 years, respectively (p < 0.001). There was no significant change in the degree of liver steatosis and necroinflammation. The mean liver fibrosis score increased from 0.1 to 0.9 (p = 0.015). No sign of advanced liver disease was observed during the 5-year follow-up. CONCLUSION The modified jejunoileal bypass is very effective in inducing and maintaining weight loss for 5 years and does not lead to hepatic failure or rapid progression of liver disease.

Abstract
Evidence-based management guidelines for non-alcoholic fatty liver disease (NAFLD) are lacking in the Asia-Pacific region or elsewhere. This review reports the results of a systematic literature search and expert opinions. The Asia-Pacific Working Party on NAFLD (APWP-NAFLD) has generated practical recommendations on management of NAFLD in this region. NAFLD should be suspected when there are metabolic risk factors and/or characteristic changes on hepatic ultrasonography. Diagnosis by ultrasonography, assessment of liver function and complications, exclusion of other liver diseases and screening for metabolic syndrome comprise initial assessment. Liver biopsy should be considered when there is diagnostic uncertainty, for patients at risk of advanced fibrosis, for those enrolled in clinical trials and at laparoscopy for another purpose. Lifestyle measures such as dietary restrictions and increased physical activity (aerobic exercise) should be encouraged, although the best management strategy to achieve this has yet to be defined. Complications of metabolic syndrome should be screened for regularly. Use of statins to treat hypercholesterolemia is safe and recommended; frequent alanine aminotransferase (ALT) monitoring is not required. Obese patients who do not respond to lifestyle measures should be referred to centers specializing in obesity management; consideration should be given to bariatric surgery or gastric ballooning. The role of pharmacotherapy remains investigational and is not recommended for routine clinical practice. Non-alcoholic fatty liver disease should be recognized as part of the metabolic syndrome and managed in a multidisciplinary approach that addresses liver disease in the context of risk factors for diabetes and premature cardiovascular disease. Lifestyle changes are the first line and mainstay of management.

Abstract
Morbid obesity is a growing public health concern with multiple associated cardiovascular comorbidities. Bariatric surgery has emerged as a safe and effective treatment for morbidly obese patients at risk for, or already suffering from, cardiovascular disease. Weight loss induced by the surgery has been shown to improve cardiovascular risk factors, cardiac structure and function, and the clinical course of established cardiovascular disease. The role of adipocyte-derived cytokines in mediating cardiovascular pathophysiology in obesity-and its modulation after weight loss-is under active investigation.

Abstract
BACKGROUND Many patients undergoing bariatric surgery have severe comorbidities, including obstructive sleep apnea (OSA). We suspected that sleep apnea was underdiagnosed in our study population. METHODS A retrospective chart review of our bariatric database was conducted comparing OSA evaluation based on clinical parameters (Era 1) with mandatory OSA evaluation for all patients (Era 2). RESULTS In both Era groups approximately 19% of patients presented to our program with an established diagnosis of OSA. In Era 1 this increased to 56% based on clinical parameters and in Era 2 this increased to 91% with mandatory polysomnography testing of all patients. CONCLUSIONS OSA is grossly underdiagnosed in patients with morbid obesity presenting for bariatric surgery. Clinical evaluation continues to miss a substantial percentage of patients with OSA. Mandatory testing of all patients for OSA with polysomnography before bariatric surgery is recommended.

Abstract
BACKGROUND To study the mortality among morbidly obese patients qualifying for bariatric surgery. Mortality from bariatric surgery for morbid obesity has been widely reported; however, little is known about the mortality in morbidly obese patients who defer surgery. METHODS Consecutive patients evaluated for bariatric surgery with an initial encounter between 1997 and 2004 were identified. The Social Security Death Index and office records were used to identify mortality through 2006. We conducted telephone interviews to determine whether the 305 patients who did not undergo bariatric surgery at our institution had undergone the surgery elsewhere. Using Cox proportional hazards models, we compared the mortality in patients undergoing surgery with that of those who did not. To evaluate bias resulting from missing data, we conducted analyses assuming that all patients with missing data had (1) undergone surgery and (2) not undergone surgery. RESULTS A total of 908 patients underwent bariatric surgery (880 patients at our institution and 28 patients elsewhere). A total of 112 patients did not undergo surgery. Data regarding surgery on 165 patients could not be obtained. The mortality in those patients who did not undergo surgery was 14.3% compared with 2.9% for those who did undergo surgery. Adjusting for age, gender, and body mass index, patients who had undergone surgery had an 82% reduction in mortality (hazard ratio 0.18, 95% confidence interval 0.09-0.35, P <.0001). Sensitivity analysis, assuming that all patients with missing data received surgery resulted in an 85% mortality reduction (P <.001) and assuming that patients did not receive surgery resulted in a 50% mortality reduction (P = .04). CONCLUSIONS Mortality among morbidly obese patients without surgery was 14.3% during the study period. Surgical intervention offered a 50%-85% mortality reduction benefit.
