    Psychosocial evaluation is recommended prior to bariatric surgery. Practice guidelines have been published on assessment methods for bariatric surgery candidates, but they have not emphasized ethical issues with this population. This review outlines ethical and professional considerations for behavioral healthcare providers who conduct pre-surgical assessments of bariatric surgery candidates by merging ethical principles for mental health professionals with current practices in pre-surgical assessments. Issues discussed include the following: (a) establishing and maintaining competence, (b) obtaining informed consent, (c) respecting confidentiality, (d) avoiding bias and discrimination, (e) avoiding and addressing dual roles, (f) selecting and using psychological tests, and (g) acknowledging limitations of psychosocial assessments.

    Full Text Available Context Obesity in the elderly is associated with exacerbation of functional decline (dependency, that occurs with aging, because of decreased muscle mass and strength, and increased joint dysfunction. Consequently, there is progressive loss of independence, autonomy, chronic pain and impaired quality of life. The weight loss can bring benefits in all these aspects, especially when accompanied by exercises. Elderly patients with morbid obesity may be submitted to surgical treatment, taking into account that the massive weight loss, eventually caused by bariatric surgery, may exacerbate the loss of muscle mass and nutritional complications that may bring harm to the overall health and quality of life of these patients. The functional assessment of elderly patients, candidates for bariatric surgery and the extent to which surgery can bring benefits to the patients, in the field of functionality, has still to be determined. Objective To describe profile functionality in obese elderly referred to a bariatric surgery program. Methods Patients with age ≥60 and BMI ≥35 underwent comprehensive geriatric assessment that evaluates co morbidities, medication use, ability to perform basic activities of daily living and instrumental activities of daily living, and the “Timedupandgo” test to evaluate mobility, whose cut-off point was ≤10 seconds. Statistical analysis was performed in order to see if there is a positive correlation of dependency with BMI and age (over or under 65 years. Results Forty subjects have completed evaluation. The mean age was 64.1 years (60-72 and 75% were women. They had an average weight of 121.1 kg (72.7-204 and a mean BMI of 47.2 kg/m2 (35.8-68.9. 16 patients (40% have shown dependency for activities of daily living, 19 (47,5% for instrumental activities of daily living and 20 patients (50% had a “Timedupandgo” test over 10 seconds.

    Full Text Available Abstract Obesity is recognized as a global health crisis. Bariatric surgery offers a treatment that can reduce weight, induce remission of obesity-related diseases, and improve the quality of life. In this article, we outline the different options in bariatric surgery and summarize the recommendations for selecting and assessing potential candidates before proceeding to surgery. We present current data on post-surgical outcomes and evaluate the psychosocial and economic effects of bariatric surgery. Finally, we evaluate the complication rates and present recommendations for post-operative care.

    Objective To determine whether binge eating disorder (BED) status is associated with medical comorbidities in obese adults scheduled for bariatric surgery. Method The study utilized Longitudinal Assessment of Bariatric Surgery-2 data obtained from 6 clinical centers around the United States. This is a well-phenotyped cohort of individuals who were evaluated within 30 days prior to their scheduled surgery using standardized protocols. In the cohort, 350 participants were classified as having BED and 1875 as not having BED (non-BED). Multivariable logistic regression was used to determine whether BED status was independently related to medical comorbidities. As an exploratory analysis, significance was based on nominal P-values (p<.05). Holm-adjusted P-values were also reported. Results After adjusting for age, sex, education and body mass index, BED status was independently associated with 4 of 15 comorbidities (i.e., impaired glucose levels (odds ratio [OR]=1.45 (95%CI: 1.12–1.87), high triglycerides (OR=1.28 (95%CI: 1.002–1.63) and urinary incontinence (OR=1.30 (95%CI: 1.02,1.66) all being more common among the BED sample, and severe walking limitations being less common in the BED sample (OR=0.53 (95%CI: 0.29–0.96)). With further adjustment for psychiatric/emotional health indicators, BED status was independently associated with 3 comorbidities (impaired glucose levels (OR=1.36 (95%CI: 1.04–1.79), cardiovascular disease (OR=0.50 (95%CI: 0.30–0.86) and severe walking limitations (OR=0.38 (95%CI: 0.19–0.77)). However, Holm’s adjusted P-values for all variables were greater than .05. Discussion The results suggest the possibility of a contribution of BED to risk of specific medical comorbidities in severely obese adults. PMID:25778499

    Bariatric surgery reduces mortality for Americans who meet candidacy criteria and have insurance coverage. Unfortunately, some medically suitable candidates are denied or delayed during insurance approval processes. The long-term impact of such care delays on survival is unknown. Using a prospectively maintained bariatric intake database, we identified consecutive applicants who were evaluated and medically cleared by our multidisciplinary care team and for whom insurance approval was requested. We compared survival in those who were initially approved by their insurance carriers (controls) and those who were initially denied coverage (subjects). Mortality was determined using the Social Security Death Index. Kaplan-Meier survival curves were plotted and the log-rank test for significance was applied. From August 2003 to December 2008, 463 patients (391 females, mean age 45 ± 10 years, mean body mass index 52.5 ± 9.4 kg/m(2)) were medically cleared for a bariatric procedure. Of these, 363 were approved by insurance on initial request, whereas 100 were denied. Given the study's intention to measure the aggregate impact of delays and denials, nine patients who later came to operation after appeal or coverage change were maintained in the subject cohort. During 0- to 113-month follow-up, six subjects (6%) died compared with seven controls (1.9%), corresponding to a statistically significant survival benefit for patients initially approved for bariatric surgery without delay or denial (P insurance certification processes in 22 per cent of medically acceptable candidates. Processes that delay or restrict efficient access to bariatric surgery are associated with a 3-fold mortality increase. PMID:26874141

    Background : Obesity decreases the quality of life, which is aggravated by the association of comorbidities, and the binge eating disorder is directly related to body image and predisposes to overweight. Aim: Evaluate association between the presence and the level of binge eating disorder and the quality of life of the obese candidates for bariatric surgery. Methods : Cross-sectional study analyzing anthropometric data (weight and height) and socioeconomics (age, sex, marital status, education and income). The application of Binge Eating Scale was held for diagnosis of Binge Eating Disorder and the Medical Outcomes Study 36-item Short-From Health Survey to assess the quality of life. Results : Total sample studied was 96 patients, mean age 38.15±9.6 years, 80.2% female, 67.7% married, 41% with complete and incomplete higher education, 77.1% with lower income or equal to four the minimum salary, 59.3% with grade III obesity. Binge eating disorder was observed in 44.2% of patients (29.9% moderate and 14.3% severe), and these had the worst scores in all domains of quality of life SF36 scale; however, this difference was not statistically significant. Only the nutritional status presented significant statistically association with the presence of binge eating disorder. Conclusion : High prevalence of patients with binge eating disorder was found and they presented the worst scores in all domains of quality of life. PMID:26537275

    Objective: To look for correlations between lung function and cardiac dimension variables in morbidly obese patients, in order to test the hypothesis that the relative size of the small airways is independently correlated with left ventricular hypertrophy. Methods: This was a retrospective study involving 192 medical records containing a clinical protocol employed in candidates for bariatric surgery between January of 2006 and December of 2010. Results: Of the 192 patients evaluated, 39 (10 males and 29 females) met the inclusion criteria. The mean BMI of the patients was 49.2 ± 7.6 kg/m2, and the mean age was 35.5 ± 7.7 years. The FEF25-75/FVC, % correlated significantly with left ventricular posterior wall thickness and relative left ventricular posterior wall thickness, those correlations remaining statistically significant (r = −0.355 and r = −0.349, respectively) after adjustment for weight, gender, and history of systemic arterial hypertension. Stepwise multivariate linear regression analysis showed that FVC and FEV1 were the major determinants of left ventricular mass (in grams or indexed to body surface area). Conclusions: A reduction in the relative size of the small airways appears to be independently correlated with obesity-related cardiac hypertrophy, regardless of factors affecting respiratory mechanics (BMI and weight), gender, or history of systemic arterial hypertension. However, FEV1 and FVC might be important predictors of left ventricular mass in morbidly obese individuals. PMID:26578134

    Full Text Available Aims: To analyze changes in the general and specific psychopathology of morbidly obese bariatric surgery (BS candidates after cognitive behavioral therapy (CBT and assess differences between patients with and without binge eating disorder (BED and between patients with obesity grades III and IV, studying their influence on weight loss. Methods: 110 consecutive morbidly obese BS candidates [77 females; aged 41 ± 9 yrs; body mass index 49.1 ± 9.0 kg/m²] entered a three-month CBT program (12 two-hour sessions before BS. Participants were assessed with general and specific psychopathology tests pre-and post-CBT. Data were analyzed according to the degree of obesity and presence/absence of BED. Results: At baseline, BED patients were more anxious and depressive with lower self-esteem and quality of life versus non-BED patients (p 10% in 61%, with no intergroup differences. Conclusions: CBT is effective to treat psychological comorbidity in BS candidates, regardless of the presence of BED and degree of obesity.

    Problematic eating behaviors, such as emotional eating, and food addiction, may affect weight; however, little is known about these eating behaviors, especially among those seeking bariatric surgery. Therefore, the purpose of this study was to estimate the prevalence of problematic eating behaviors and to investigate their relationship with other eating behaviors, body mass index (BMI), and psychiatric symptoms. There were 142 patients who completed a required psychiatric evaluation prior to bariatric surgery. Of these, 16.9 % met criteria for a food addiction and 25.4-40.7 % endorsed emotional eating, depending on type of emotional eating. The number of food addiction symptoms endorsed was related to emotional eating. Both food addiction and emotional eating were related to anxiety and depressive symptoms. However, surprisingly, BMI was not related to a food addiction diagnosis, emotional eating scores, or psychiatric symptoms. Results from this study suggest that problematic eating behaviors are occurring among bariatric surgery candidates. Furthermore, this study may help to address the conflicting research regarding the effects of psychiatric symptoms on weight-loss outcomes. Perhaps it is the problematic eating behaviors (e.g., food addiction and emotional eating) that are associated with psychiatric symptoms that could be influencing outcomes. Future research should evaluate treatments for problematic eating behaviors and whether treatments improve weight-loss success. PMID:24878835

    2007-04-01

    Bariatric surgery as a means to treat obesity is becoming increasingly common in the United States. An early form of bariatric surgery, the jejunoileal bypass, had to be abandoned in 1980 due to numerous complications, including hyperoxaluria and kidney stones. Current bariatric procedures have not been systematically evaluated to determine if they cause hyperoxaluria. Presented here are data showing that hyperoxaluria is the major metabolic abnormality in patients with bariatric surgery who form kidney stones. Further studies are needed to assess the prevalence of hyperoxaluria in all patients with bariatric surgery.

    Full Text Available Background In 2005, obesity rate was declared 396 million worldwide, which has been doubled in the last 20 years (compared with 1985. Obesity has a strong correlation with a pool of comorbidities and consequences. Although many modules, including behavioural approach and medications have presented particular short-term unreliable methods to reduce and control the body weight in morbid obesity, only 5 - 10% of weight loss was achieved, which is usually regained overtime, compared with 50 - 75% success rate in bariatric surgery. Objectives This retrospective study tried to monitor weight loss after LRYGB and LSG in morbid obese patients referred to a known center in Tehran through a one-year follow up. Materials and Methods Participants were selected regarding the U.S. National Institute of Health (NIH guidelines, which indicates BMI > 40 kg/m2 alone, or BMI > 35 kg/m2 in addition to comorbidities and failure of non-surgical attempts to control their weight. They were visited at points of one, three, six, and 12 months postoperatively to collect information about weight loss, BMI, and complications in addition to percent excess weight loss (EWL%. The percentage of failure was computed to the proportion of patients who had EWL% < 25 to the total number of operated patients in a year. Results Significant decrease in BMI and weight were achieved in all postoperative visits (for all of them, P value < 0.0001, while no significant difference was found in which the parameters between two studied procedures were in this regard. Conclusions To sum up, LRYGB and LSG deserve an overall preference not only in current study, but also in the majority of performances up to now. Nevertheless it is urgent the relevant studies to confirm the preference or improve this kind of bariatric surgery in order to diminish complications as far as possible.

    This is a single-arm, pre and post effectiveness study that evaluated the impact of a comprehensive workplace lifestyle program on severe obesity among high cardiovascular disease risk individuals in a large, diverse employee population. Employees of Baptist Health South Florida were considered eligible to participate if they had 2 or more of the following cardiometabolic risk factors: total cholesterol ≥200 mg/dL, systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, hemoglobin A1c ≥6.5%, body mass index ≥30kg/m(2). Participants received a personalized diet plan and physical activity intervention, and were followed for 1 year. Data on anthropometric measurements, blood pressure, blood glucose, and other biochemical measures were collected. Participants' body mass index was calculated and their eligibility for bariatric surgery (BS) also assessed. A total of 297 persons participated in the program; 160 participants completed all procedures through 12 months of follow-up. At baseline, 34% (n = 100) of all participants were eligible for BS. In an intention-to-treat analysis, 27% (n = 27) of BS eligible participants at baseline became ineligible after 12 months. Considering program completers only, 46% of BS eligible participants at baseline became ineligible. Irrespective of BS eligibility at 12 months, mean values of cardiometabolic risk factors among program completers improved after the follow-up period. Workplace wellness programs provide an important option for weight loss that can obviate the need for BS, reduce cardiovascular disease risk, and potentially reduce costs. However, in designing future worksite lifestyle interventions, measures should be taken to improve participation and retention rates in such programs. PMID:26760281

    2013-02-01

    Bariatric surgery is gaining in popularity, due to globally increasing rates of obesity. In the UK, this has manifested as a 14-fold increase in bariatric surgery between 2004 and 2010, making it necessary to develop strategies to manage women who become pregnant following bariatric surgery. This review paper has explored all the current evidence in the literature and provided a comprehensive management strategy for pregnant women following bariatric surgery. The emphasis is on a multidisciplinary team approach to all aspects of care. Adequate pre-conception and antenatal and postnatal care is essential to good pregnancy outcomes with emphasis on appropriate nutritional supplementation. This is especially important following malabsorptive procedures. There is no evidence to suggest that pregnancy outcome is worse after bariatric surgery, though women who remain obese are prone to obesity-related risks in pregnancy. Neonatal outcome post-bariatric surgery is no different from the general population. PMID:23445128

    A 4-year-old girl was referred for evaluation for a mild but persistent serum aspartate aminotransferase (AST) elevation detected incidentally during routine blood screening for a skin infection. Serum creatine kinase activity was found to be increased. Immuno-histochemical study for dystrophin in her muscle biopsy showed results consistent with a carrier state for muscular dystrophy. Molecular work-up showed the proposita to be a carrier of a deletion mutation of exon 48 of the dystrophin gene. Four male relatives also had the deletion mutation, yet showed no clinical symptoms of muscular dystrophy (age range 8-58 yrs). Linkage analysis of the dystrophin gene in the family showed a spontaneous change of an STR45 allele, which could be due to either an intragenic double recombination event, or CA repeat length mutation leading to identical size alleles. To our knowledge, this is the first documentation of an asymptomatic dystrophinopathy in multiple males of advanced age. Based on molecular findings, this family would be given a diagnosis of Becker muscular dystrophy. This diagnosis implies the development of clinical symptoms, even though this family is clearly asymptomatic. This report underscores the caution which must be exercised when giving presymptomatic diagnoses based on molecular studies. 28 refs., 4 figs., 1 tab.

    Surgery has consistently been demonstrated to be the most effective long-term therapy for the treatment of obesity. However, despite excellent outcomes with current procedures, most patients with obesity- and weight-related comorbidities who meet criteria for surgical treatment choose not to pursue surgery out of fear of operative risks and complications or concerns about high costs. Novel minimally invasive procedures and devices may offer alternative solutions for patients who are hesitant to pursue standard surgical approaches. These procedures may be used for primary treatment of obesity, early intervention for patients approaching morbid obesity, temporary management prior to bariatric surgery, or revision of bypass surgery associated with weight regain. Novel bariatric procedures can in general be divided into four categories: endoluminal space-occupying devices, gastric suturing and restrictive devices, absorption-limiting devices, and neural-hormonal modulating devices. Many of these are only approved as short-term interventions, but these devices may be effective for patients desiring low-risk procedures or a transient effect. We will see the expansion of indications and alternatives for metabolic surgery as these techniques gain approval.

    Bariatric surgery is an effective treatment strategy for patients with morbid obesity that can result in effective weight loss, resolution of diabetes mellitus and other weight related complications, and even improved mortality. However, it also appears that hyperoxaluria is common after modern bariatric surgery, perhaps occurring in up to 50% of patients after Rouxen-Y gastric bypass. Although increasing numbers of patients are being seen with calcium oxalate kidney stones after bariatric surgery, and even a few with oxalosis and renal failure, the true risk of these outcomes remains unknown. The mechanisms that contribute to this enteric hyperoxaluria are also incompletely defined, although fat malabsorption may be an important component. Since increasing numbers of these procedures are likely to be performed in the coming years, further study regarding the prevalence and mechanisms of hyperoxaluria and kidney stones after bariatric surgery is needed to devise effective methods of treatment in order to prevent such complications.

  5. Asymptomatic ischemic cerebral lesions

    International Nuclear Information System (INIS)

    For the purpose of studying the incidence, pathomorphology and etiology of asymptomatic ischemic cerebral lesions, we carried out a brain MRI study on 65 patients with diabetes mellitus accompanied with hypertension who are thought to belong to a high risk group of ischemic cerebrovascular diseases. Excluding the abnormality of tendon reflex due to diabetic neuropathy, sixty percent of the total patients had some mild neurological signs and symptoms, most of them was discrepancy in tendon reflex. The percentage of the patients in whom MRI disclosed some abnormalities was as high as 70%, they were lacunar stroke, multiple lacunar state, cortical infarct, and patchy high signal lesions visible only in the T2 weighted image. Lacunes or these patchy high signal lesions (considered to be the dilatation of the perivascular space or true lacunes) tended to be found along the border zone or the terminal zone. These results indicate that asymptomatic patients in whom MRI discloses the abnormalities should be considered as candidates for the future onset of multi-infarct. (author)

    Full Text Available Craniopharyngiomas (CP are epithelial neoplasms generally found in the area of the pituitary and hypothalamus. Despite benign histology, these tumors and/or their treatment often result in significant, debilitating disorders of endocrine, neurological, behavioral, and metabolic systems. Severe obesity is observed in a high percentage of patients with CP resulting in significant comorbidities and negatively impacting quality of life. Obesity occurs as a result of hypothalamic damage and disruption of normal homeostatic mechanisms regulating energy balance. Such pathological weight gain, termed hypothalamic obesity (HyOb, is often severe and refractory to therapy.Unfortunately, neither lifestyle intervention nor pharmacotherapy has proven truly effective in the treatment of CP-HyOb. Given the limited choices and poor results of these treatments, several groups have examined bariatric surgery as a treatment alternative for patients with CP-HyOb. While a large body of evidence exists supporting the use of bariatric surgery in the treatment of exogenous obesity and its comorbidities, its role in the treatment of HyOb has yet to be well defined. To date, the existing literature on bariatric surgery in CP-HyOb is largely limited to case reports and series with short term follow-up. Here we review the current reports on the use of bariatric surgery in the treatment of CP-HyOb. We also compare these results to those reported for other populations of HyOb, including Prader-Willi Syndrome and patients with melanocortin signaling defects. While initial reports of bariatric surgery in CP-HyOb are promising, their limited scope makes it difficult to draw any substantial conclusions as to the long term safety and efficacy of bariatric surgery in CP-HyOb. There continues to be a need for more robust, controlled, prospective trials with long term follow-up in order to better define the role of bariatric surgery in the treatment of all types of hypothalamic

    Childhood obesity remains a significant public health issue. Approximately 8% of adolescent girls and 7% of adolescent boys have severe (≥class 2) obesity. Adolescent severe obesity is associated with numerous comorbidities, and persists into adulthood. Bariatric surgery is the most effective treatment available, resulting in major weight loss and resolution of important comorbid conditions. Clinical practice guidelines for pediatric obesity treatment recommend consideration of surgery after failure of behavioral approaches. Careful screening and postoperative management of patients by a multidisciplinary team is required. Long-term studies are needed to assess the impact of adolescent bariatric surgery. PMID:27519138

    AIM: To understand the lived experience of body image in young women after obesity surgery. BACKGROUND: Quantitative studies have documented that health-related quality of life and body image are improved after bariatric surgery, probably due to significant weight loss.

    2011-01-01

    Full Text Available Maternal obesity is a major cause of obstetric morbidity and mortality. With surgical procedures to facilitate weight loss becoming more widely available and demanded and increasing number of women becoming pregnant after undergoing bariatric surgery, it is important and timely to consider the outcome of pregnancy following bariatric surgery. This paper aims to synthesize the current evidence regarding pregnancy outcomes after bariatric surgery. It concludes that bariatric surgery appears to have positive effects on fertility and reduces the risk of gestational diabetes and preeclampsia. Moreover, there appears to be a reduced incidence of fetal macrosomia post-bariatric procedure, although there remains uncertainty about the increased rates of small-for-gestational age and intrauterine growth restricted infants, as well as premature rupture of membranes in this group. A number of case reports highlight that pregnancy following bariatric surgery is not without complications and it must be managed as high risk by the multidisciplinary team.

    Full Text Available Abstract. Weight recidivism in bariatric surgery failure is multifactorial. It ranges from inappropriate patient selection for primary surgery to technical/anatomic issues related to the original surgery. Most bariatric surgeons and centers focus on primary bariatric surgery while weight recidivism and its complications are very much secondary concerns. Methods. We report on our initial experience having established a dedicated weight recidivism and revisional bariatric surgery clinic. A single surgeon, dedicated nursing, dieticians, and psychologist developed care maps, goals of care, nonsurgical candidate rules, and discharge planning strategies. Results. A single year audit (2012 of clinical activity revealed 137 patients, with a mean age 49 ± 10.1 years (6 years older on average than in our primary clinic, 75% of whom were women with BMI 47 ± 11.5. Over three quarters had undergone a vertical band gastroplasty while 15% had had a laparoscopic adjustable gastric band. Only 27% of those attending clinic required further surgery. As for primary surgery, the role of the obesity expert clinical psychologist was a key component to achieving successful revision outcomes. Conclusion. With an exponential rise in obesity and a concomitant major increase in bariatric surgery, an inevitable increase in revisional surgery is becoming a reality. Anticipating this increase in activity, Alberta Health Services, Alberta, Canada, has established a unique and dedicated clinic whose early results are promising.

    Full Text Available INTRODUCTION: Morbid obesity has multiple implications for psychological and physical health. Bariatric surgery has been selected as the treatment of choice for this chronic disease, despite the controversial impact of the surgery on psychosocial health. The objective of this study was to describe candidates for bariatric surgery and analyze changes in weight, psychopathology, personality, and health problems and complaints at 6- and 12- month follow-up assessments. METHODS: Thirty obese patients (20 women and 10 men with a mean age of 39.17±8.81 years were evaluated in different dimensions before surgery and 6 and 12 months after the procedure. RESULTS: Six and 12 months after bariatric surgery, patients reported significant weight loss and a significant reduction in the number of health problems and complaints. The rates of self-reported psychopathology were low before surgery, and there were no statistically significant changes over time. The conscientiousness, extraversion, and agreeableness dimensions increased, but neuroticism and openness remained unchanged. All changes had a medium effect size. CONCLUSIONS: Our results suggest that patients experience significant health improvements and some positive personality changes after bariatric surgery. Even though these findings underscore the role of bariatric surgery as a relevant treatment for morbid obesity, more in-depth longitudinal studies are needed to elucidate the evolution of patients after the procedure.

    2014-05-01

    Over the past 10 years, a variety of reports have linked bariatric surgery to metabolic changes that alter kidney stone risk. Most of these studies were retrospective, lacked appropriate controls, or involved bariatric patients with a variety of inclusion criteria. Despite these limitations, recent clinical and experimental research has contributed to our understanding of the pathophysiology of stone disease in this high-risk population. This review summarizes the urinary chemistry profiles that may be responsible for the increased kidney stone incidence seen in contemporary epidemiological bariatric studies, outlines the mechanisms of hyperoxaluria and potential therapies through a newly described experimental bariatric animal model, and provides a focused appraisal of recommendations for reducing stone risk in bariatric stone formers.

    Increasing numbers of patients who have undergone bariatric surgery are now presenting to orthopedic surgeons for elective arthroplasties. In addition, orthopedic surgeons themselves are referring more patients for consideration of bariatric surgery in anticipation of future elective procedures. Although the full effects of bariatric surgery on metabolism are not yet known, the altered digestion associated with these surgeries poses several issues for orthopedic surgeons. In this article, we address 3 aspects of care of this class of patient: review of the most commonly performed procedures and their metabolic consequences; suggested preoperative assessment of bariatric patients for any conditions that should be corrected before surgery; and evaluation of outcomes of elective procedures performed after bariatric surgery. Awareness of the unique characteristics of this group of patients helps minimize the potential for complications of planned orthopedic surgeries.

    Full Text Available Bariatric surgery is the most effective therapeutic option for obese patients; however, it carries substantial risks, including procedure-related complications, malabsorption, and hormonal disturbance. Recent years have seen an increase in the bariatric surgeries performed utilizing either an independent or a combination of restrictive and malabsorptive procedures. We review some complications of bariatric procedures more specifically, hypoglycemia and osteoporosis, the recommended preoperative assessment and then regular follow up, and the therapeutic options. Surgeon, internist, and the patient must be aware of the multiple risks of this kind of surgery and the needed assessment and follow up.

    The objective was to evaluate the results of bariatric surgery in patients in the late postoperative period using the Bariatric Analysis and Reporting Outcome System (BAROS). This cross-sectional study was conducted from November 2011 to June 2012 at a hospital in the state of Ceará, Brazil. Data were collected from 92 patients using the BAROS protocol, which analyzes weight loss, improved comorbidities, complications, reoperations and Quality of Life (QoL). Data were analysed using the chi-squared test, Fischer's exact test and the Mann-Whitney test. There was a reduction in the Body Mass Index (47.2±6.8 kg/m2 in the pre-operatory and 31.3±5.0 kg/m2 after surgery, p<0.001). The comorbidity with the highest resolution was arterial hypertension (p<0.001), and QV improved in 94.6% of patients. The main complications were hair loss, incisional hernia and cholelithiasis. The surgery provided satisfactory weight loss and improvements in the comorbidities associated to a better QL. Use of the BAROS protocol allows nurses to plan interventions and maintain the good results. PMID:26098798

    Full Text Available Context Morbid obesity is associated with various co-morbidities, including chronic venous insufficiency. Bariatric surgery is the only effective treatment for morbid obesity, but with potential risks and possible complications, including venous thromboembolism. Objective To determine the prevalence of clinical and ultrasonographic signs of chronic venous insufficiency in morbid obese patients in preparation for bariatric surgery and the incidence of post-operative venous thromboembolic disease. Methods Patients on work-up for bariatric surgery of Centro Terapêutico Especializado em Fígado (CETEFI and Pro-Gastro surgical teams of the Hospital Beneficência Portuguesa de São Paulo were included. The analysed data were pre-operative findings for venous insufficiency (CEAP - clinical, etiological, anatomical, physiopathologic - classification and venous ultrassonographic findings, type of surgery (open or laparoscopic, abdominal circumference, body mass index (BMI and post-operative ultrassonography search for venous insufficiency and deep venous thrombosis. Results Between March 2007 and December 2009, 95 patients candidates for bariatric surgery had clinical and duplex scan evaluation of the lower limbs venous system. Of the 95 patients, 53 were submitted to the surgical procedure. There was a predominance of women (77.9%, the average age was 38.5 years, average preoperative weight 124.6 kg and average BMI of 45.5 kg/m2. Regarding obesity, 16.8% were obese, and 83.1% were morbidly obese. In relation to the venous findings, 86.3% of the patients did fit CEAP classification less than 3 and 13.7% greater than or equal to 3. Among the post-operative complications, there were four cases of wound infection. Three patients developed post-operative distal venous thrombosis (7.5%, but no one had clinically manifested pulmonary embolism. Conclusion No relation between BMI, CEAP classification and venous ultrassonographic findings were found. Although

    Bariatric surgery dramatically alters the normal stomach anatomy resulting in a significant incidence of hiatal hernia and gastroesophageal reflux disease. Although the majority of patients remain asymptomatic, many complain of severe heartburn refractory to medical management and additional highly atypical symptoms. Here, we describe the diagnosis and treatment regarding four cases of symptomatic hiatal hernia following bariatric surgery presenting with atypical symptoms in the University Hospital, USA. Four patients presented following laparoscopic Roux-en-Y gastric bypass or duodenal switch/pancreaticobiliary bypass (DS) with disabling and intractable midepigastric abdominal pain characterized as severe and radiating to the jaw, left shoulder, and midscapular area. The pain in all cases was described as paroxysmal and not necessarily associated with eating. All four patients also experienced nausea, vomiting, and failure to thrive at various intervals following laparoscopic bariatric surgery. Routine workup failed to produce any clear mechanical cause of these symptoms. However, complimentary use of multidetector CT and upper gastrointestinal contrast studies eventually revealed the diagnosis of hiatal hernia. Exploration identified the presence of a type I hiatal hernia in all four patients, with the stomach staple lines densely adherent to the diaphragm and parietal peritoneum. Operative intervention led to immediate and complete resolution of symptoms. The presence of a hiatal hernia following bariatric surgery can present with highly atypical symptoms that do not resolve without operative intervention. Recognition of this problem should lead to the consideration of surgery in cases where patients are dependent on artificial nutritional support and whose symptoms are poorly controlled with medication alone.

  9. Bariatric surgery: assessing opportunities for value innovation.

    2005-03-01

    Obesity has been increasing over the past two decades, and the amount of medical and media attention given to bariatric surgery as a promising option for morbidly obese individuals is growing. The growth of bariatric surgery also has been attributed to improved surgical technique, the increase in surgeons trained in laparoscopic procedures, as well increased public awareness with celebrities having successfully undergone surgery. The number of surgeons and hospitals offering bariatric services is increasing. How then does a surgeon or a hospital develop a competitive strategy? The first step is to understand the health-care industry. The key forces are rivalry among present competitors, and the bargaining power of suppliers and buyers. While bariatric surgery currently is in a growth phase, time and competition will force practitioners to compete on the basis of price, unless they find true competitive advantage. Value innovation, is a means of creating new marketing space by looking across the conventionally defined boundaries of business--across substitute industries, across strategic groups, across buyer groups, across complementary product and service offerings, and across the functional-emotional orientation of an industry. One can compete by offering similar services focusing primarily on cost efficiencies as the key to profitability. Alternatively, one can break free from the pack by innovating and focusing on delivering superior value to the customer. As the market for bariatric surgery becomes increasingly overcrowded, profitable growth is not sustainable without developing a clear differential advantage in the market. Value innovation allows you to develop that advantage. PMID:15846452

    Obesity is a significant health concern and is associated with an increased risk of nephrolithiasis, particularly in women. The underlying pathophysiology of stone formation in obese patients is thought to be related to insulin resistance, dietary factors, and a lithogenic urinary profile. Uric acid stones and calcium oxalate stones are common in these patients. Use of surgical procedures for obesity (bariatric surgery) has risen over the past two decades. Although such procedures effectively manage obesity-dependent comorbidities, several large, controlled studies have revealed that modern bariatric surgeries increase the risk of nephrolithiasis by approximately twofold. In patients who have undergone bariatric surgery, fat malabsorption leads to hyperabsorption of oxalate, which is exacerbated by an increased permeability of the gut to oxalate. Patients who have undergone bariatric surgery show characteristic 24 h urine parameters including low urine volume, low urinary pH, hypocitraturia, hyperoxaluria and hyperuricosuria. Prevention of stones with dietary limitation of oxalate and sodium and a high intake of fluids is critical, and calcium supplementation with calcium citrate is typically required. Potassium citrate is valuable for treating the common metabolic derangements as it raises urinary pH, enhances the activity of stone inhibitors, reduces the supersaturation of calcium oxalate, and corrects hypokalaemia. Both pyridoxine and probiotics have been shown in small studies to reduce hyperoxaluria, but further study is necessary to clarify their effects on stone morbidity in the bariatric surgery population.

    Huang Chih-Kun

    2011-01-01

    Full Text Available Background: Bariatric surgery has been established as the best option of treatment for morbid obesity. In recent years single-incision laparoscopic surgery (SILS has emerged as another modality of carrying out the bariatric procedures. While SILS represents an advance, its application in morbid obesity at present is limited. In this article, we review the technique and results of SILS in bariatric surgery. Methods: The PubMed database was searched and totally 11 series reporting SILS in bariatric surgery were identified and analyzed. The case reports were excluded. Since 2008, 114 morbidly obese patients receiving SILS bariatric surgeries were reported. Results: The procedures performed included SILS gastric banding, sleeve gastrectomy and gastric bypass. No mortality was reported in the literatures. Sixteen patients (14.05% needed an additional incision for a liver retractor, a trocar or for conversion. Only one complication of wound infection was reported in these series. All the surgeons reported that the patients were highly satisfied with the scar. Conclusion: Because of abundant visceral and subcutaneous fat and multiple comorbidities in morbid obesity, it is more challenging for surgeons to perform the procedures with SILS. It is clear that extensive development of new instruments and technical aspects of these procedures as well as randomized studies to compare them with traditional laparoscopy are essential before these procedures can be utilized in day-to-day clinical practice.

  13. Asymptomatic uterine fibroids.

    Science.gov (United States)

    Divakar, Hema

    2008-08-01

    It is estimated that at least 50% of fibroids are asymptomatic, but this figure is likely to be an underestimate as it is based on women in whom fibroids are found incidentally during another procedure (e.g. cervical screening), and there is little, if any, data from population studies on the true incidence of fibroids. If a prevalence of 50% by 50 years of age is accepted, a large number of women have asymptomatic fibroids. Working on the cliché, 'if it ain't broken, don't fix it', it may seem surprising that there should be a chapter dedicated to the issue of asymptomatic fibroids, since the simplistic approach might be to leave the asymptomatic fibroids well alone. However, asymptomatic fibroids may become symptomatic in the future, so it may be wiser to treat fibroids before they grow to a size when they become symptomatic, or treatment becomes more challenging, especially in young women who may desire fertility at a later stage, and in view of the fact that many women are starting their families in their mid-thirties when they have a 30% chance of having a fibroid(s). Despite their common occurrence, fibroids are still poorly understood. It is not known why they form in the first place, what determines their number and ultimate size, the best treatment approaches, or the factors that determine which women develop symptoms. Even when women present with disorders such as infertility, pelvic pain and abnormal bleeding, it is not always possible to be certain that a given myoma is not simply an innocent bystander rather than the cause of the symptom. This chapter addresses the challenging issue of what to do when fibroids are diagnosed incidentally. Firstly, there is the need to ascertain that the pelvic mass palpated is indeed a fibroid, and not an early, more sinister tumour, especially if conservative management is adopted. In addition, there is the issue of size, position and potential for becoming symptomatic at a later date. With the availability of uterine

    2014-01-01

    Full Text Available During laparoscopy, the main problems of patients who have undergone previous abdominoplasty are inadequate pneumoperitoneum secondary to fibrosis and reconstructed anatomic landmarks for trocar placement. In this study, we present our laparoscopic bariatric experience in two patients with previous abdominoplasty. The procedures were a laparoscopic sleeve gastrectomy and a robotic Roux-en-Y gastric bypass. Both operations were done successfully by an abdominal wall traction technique, cutting fibrotic tissue and choosing new landmarks. We conclude that after abdominoplasty bariatric surgery can be performed safely either using conventional laparoscopic technique or robotically.

    Schroeder, Robin; Harrison, T Daniel; McGraw, Shaniqua L

    2016-01-01

    In 2013, approximately 179,000 bariatric surgery procedures were performed in the United States, including the laparoscopic sleeve gastrectomy (42.1%), Roux-en-Y gastric bypass (34.2%), and laparoscopic adjustable gastric banding (14.0%). Choice of procedure depends on the medical conditions of the patient, patient preference, and expertise of the surgeon. On average, weight loss of 60% to 70% of excess body weight is achieved in the short term, and up to 50% at 10 years. Remission of type 2 diabetes mellitus occurs in 60% to 80% of patients two years after surgery and persists in about 30% of patients 15 years after Roux-en-Y gastric bypass. Other obesity-related comorbidities are greatly reduced, and health-related quality of life improves. The Roux-en-Y procedure carries an increased risk of malabsorption sequelae, which can be minimized with nutritional supplementation and surveillance. Overall, these procedures have a mortality risk of less than 0.5%. Cohort studies show that bariatric surgery reduces all-cause mortality by 30% to 50% at seven to 15 years postsurgery compared with patients with obesity who did not have surgery. Dietary changes, such as consuming protein first at every meal, and regular physical activity are critical for patient success after bariatric surgery. The family physician is well positioned to counsel patients about bariatric surgical options, the risks and benefits of surgery, and to provide long-term support and medical management postsurgery.

    2016-05-01

    Psychosocial factors have significant potential to affect long-term outcomes of bariatric surgery, including emotional adjustment, adherence to the recommended postoperative lifestyle regimen, weight loss outcomes, and co-morbidity improvement and or resolution. Thus, it is recommended that bariatric behavioral health clinicians with specialized knowledge and experience be involved in the evaluation and care of patients both before and after surgery. The evaluating clinician plays a number of important roles in the multidisciplinary treatment of the bariatric patient. Central among these is the role of identifying factors that may pose challenges to optimal surgical outcome and providing recommendations to the patient and bariatric team on how to address these issues. This document outlines recommendations for the psychosocial evaluation of bariatric surgery patients, appropriate qualifications of those conducting these evaluations, communication of evaluation results and suggested treatment plan, and the extension of behavioral healthcare of the bariatric patient to the entire span of the surgical and postsurgical process.

    The prevalence of morbid obesity in adolescents is rising at an alarming rate. Comorbidities known to predispose to cardiovascular disease are increasingly being diagnosed in these children. Bariatric surgery has become an acceptable treatment alternative for morbidly obese adults, and criteria have been developed to establish center-of-excellence designation for adult bariatric surgery programs. Evidence suggests that bariatric surgical procedures are being performed with increasing numbers in adolescents. We have examined and compiled the current expert recommendations for guidelines and criteria that are needed to deliver safe and effective bariatric surgical care to adolescents.

    Subcutaneous adipose tissue (scAT) in human obesity undergoes severe alteration such as fibrosis which is related to metabolic alterations and to less efficiency in losing weight after bariatric surgery. There is currently no non-invasive tool to assess fibrosis in scAT. Vibration Controlled Transient Elastography (VCTE) using FibroScan® is widely used to assess liver fibrosis in clinical practice. A novel device named AdipoScan™ which is based on VCTE has been developed by Echosens (Paris) so as to assess scAT. The objective of this study is to show the first AdipoScan clinical results. AdipoScan™ was assessed in vivo on 73 morbidly obese patients candidate for bariatric surgery who were enrolled in the Pitié Salpêtrière hospital. scAT shear wave speed measured by AdipoScan™ is significantly associated with scAT fibrosis, gender, hypertension status, total body fat mass assessed by DXA, hypertension status, glycemic, lipid, hepatic parameters and adiponectin. Results suggest that scAT evaluation before bariatric surgery can be useful in clinical practice since it is related to scAT fibrosis -who plays in role in weight loss resistance after bariatric surgery- and to obesity induced co-morbidities such as diabetes, hypertension liver dysfunction.

    Initial evidence that cognitive function improves after bariatric surgery exists. The post-surgery increase in cognitive control might correspond with a decrease of impulsive symptoms after surgery. The present study investigated cognitive function and nonfood-related impulsivity in patients with substantial weight loss due to bariatric surgery by using a comparative cross-sectional design. Fifty post-bariatric surgery patients (postBS group) who had significant percent weight loss (M = 75.94, SD = 18.09) after Roux-en-Y gastric bypass (body mass index, BMI M post = 30.54 kg/m(2), SDpost = 5.14) were compared with 50 age and gender matched bariatric surgery candidates (preBS group; BMI M pre = 48.01 kg/m(2), SDpre = 6.56). To measure cognitive function the following computer-assisted behavioral tasks were utilized: Iowa Gambling Task, Tower of Hanoi, Stroop Test, Trail Making Test-Part B, and Corsi Block Tapping Test. Impulsive symptoms and behaviors were assessed using impulsivity questionnaires and a structured interview for impulse control disorders (ICDs). No group differences were found with regard to performance-based cognitive control, self-reported impulsive symptoms, and ICDs. The results indicate that the general tendency to react impulsively does not differ between pre-surgery and post-surgery patients. The question of whether nonfood-related impulsivity in morbidly obese patients changes post-surgery should be addressed in longitudinal studies given that impulsive symptoms can be considered potential targets for pre- as well post-surgery interventions.

    ABSTRACT Objectives This cross-sectional study compared the frequency of oral periodontopathogens and H. pylori in the mouths and stomachs of obese individuals with or without periodontitis submitted to bariatric surgery. Material and Methods One hundred and fifty-four men and women aged 18-65 were conveniently distributed into four groups. Two groups were composed of individuals who underwent bariatric surgery with (BP) (n=40) and without (BNP) (n=39) periodontitis and two obese control groups with (CP) (n=35) and without (CNP) (n=40) periodontitis. The oral pathogens Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Parvimonas micra, Treponema denticola, Tannerella forsythia, Campylobacter rectus, and Helicobacter pylori were detected by a polymerase chain reaction technique using saliva, tongue and stomach biopsy samples. Results Statistical analysis demonstrated that periodontopathogens were highly frequent in the mouth (up to 91.4%). In the bariatric surgically treated group, orally, P. gingivalis, T. denticola and T. forsythia were more frequent in periodontitis, while C. rectus was more frequent in non-periodontitis subjects. Stomach biopsies also revealed the high frequency of five oral species in both candidates for bariatric surgery (91.6%) and the bariatric (83.3%) groups. H. pylori was frequently detected in the mouth (50.0%) and stomach (83.3%). In the stomach, oral species and H. pylori appeared in lower frequency in the bariatric group. Conclusions Obese individuals showed high frequencies of periodontopathogens and H. pylori in their mouths and stomachs. Bariatric surgery showed an inverse microbial effect on oral and stomach environments by revealing higher oral and lower stomach bacterial frequencies. PMID:27383704

    Bariatric surgery is currently the most effective treatment for obesity. Not only do these types of surgeries produce significant weight loss but also they improve insulin sensitivity and whole body metabolic function. The aim of this review is to explore how altered physiology of adipose tissue may contribute to the potent metabolic effects of some of these procedures. This includes specific effects on various fat depots, the function of individual adipocytes and the interaction between adipose tissue and other key metabolic tissues. Besides a dramatic loss of fat mass, bariatric surgery shifts the distribution of fat from visceral to the subcutaneous compartment favoring metabolic improvement. The sensitivity towards lipolysis controlled by insulin and catecholamines is improved, adipokine secretion is altered and local adipose inflammation as well as systemic inflammatory markers decreases. Some of these changes have been shown to be weight loss independent, and novel hypothesis for these effects includes include changes in bile acid metabolism, gut microbiota and central regulation of metabolism. In conclusion bariatric surgery is capable of improving aspects of adipose tissue function and do so in some cases in ways that are not entirely explained by the potent effect of surgery. © 2016 World Obesity.

    The fast increase in obesity has been followed by the growth in the demand for plastic surgery in formerly obese patients. The weight loss is accompanied by new dysfunctions and disorders of the outline of the body that affects the quality of life of the patient. Abdominoplasty is a cosmetic surgery procedure that aims to remove the excess of skin and the redundant fat. The aim of this paper was to analyze our experience in this field and to test how functional abdominoplasty improved quality of life in the operated patients. In our Unit from January 2012 to December 2014, 25 patients (18 women and 7 men, age: 24 - 79 years, mean: 51 years) underwent abdominoplastic surgery. Only at least six months after bariatric surgery the patients were eligible for functional abdominoplasty. Average weight of the patients before surgery was 83.5 kg (range 58 - 163 Kg); averege BMI was 31 (range 24.77 - 57). The average quantity of tissue removed was 1.765 Kg (range 250 g - 11,5 Kg). Minor complications rate was in agreement with the percentages reported in literature. No mortality and major complications have occurred in our series. The majority of patients undergoing post-bariatric abdominoplasty reported an improvement in the quality of life and psychological well-being. In our opinion, however, only a multidisciplinary (surgical, psychological, dietological) approach of the post-bariatric patient allows to maintain long-term aesthetic and functional results.

    Background: In 2009, the Ontario Bariatric Network was established to address the exploding demand by Ontario residents for bariatric surgery services outside Canada. We compared the use of postoperative hospital services between out-of-country surgery recipients and patients within the Ontario Bariatric Network. Methods: We conducted a population-based, comparative study using administrative data held at the Institute for Clinical Evaluative Sciences. We included Ontario residents who underwent bariatric surgery between 2007 and 2012 either outside the country or at one of the Ontario Bariatric Network's designated centres of excellence. The primary outcome was use of hospital services in Ontario within 1 year after surgery. Results: A total of 4852 patients received bariatric surgery out of country, and 5179 patients underwent surgery through the Ontario Bariatric Network. After adjustment, surgery at a network centre was associated with a significantly lower utilization rate of postoperative hospital services than surgery out of country (rate ratio 0.90, 95% confidence interval [CI] 0.84 to 0.97). No statistically significant differences were found with respect to time in critical care or mortality. However, the physician assessment and reoperation rates were significantly higher among patients who received surgery at a network centre than among those who had bariatric surgery out of country (rate ratio 4.10, 95% CI 3.69 to 4.56, and rate ratio 1.84, 95% CI 1.34 to 2.53, respectively). Interpretation: The implementation of a comprehensive, multidisciplinary provincial program to replace outsourcing of bariatric surgical services was associated with less use of postoperative hospital services by Ontario residents undergoing bariatric surgery. Future research should include an economic evaluation to determine the costs and benefits of the Ontario Bariatric Network. PMID:27730113

    The number of bariatric surgery procedures performed is increasing every year. Patients may be referred for radiological investigations to exclude complications not only in the early postoperative period but many months later. Radiologists who do not work in bariatric centres are therefore required to have an understanding of the complex normal anatomy and complications associated with bariatric surgery to interpret imaging studies correctly. The purpose of this article is to describe the surgical techniques and normal anatomy of the four bariatric operations performed today, review the most common problems encountered in this patient group, and to describe the imaging findings that allow the accurate diagnosis of complications. In particular, we focus on identification of the internal hernia, a grave complication of bariatric surgery often missed by radiologists.

    Obesity is now a global epidemic affecting a significant and rapidly increasing number of adults, adolescents, and children. As the incidence of obesity has increased, so has the use of bariatric surgery as a medical solution. A growing number of studies now report that, despite calcium and vitamin D supplementation, the most frequently performed types of bariatric surgery, the Roux-en-Y gastric bypass and the sleeve gastrectomy, cause significant ongoing bone loss. In resources available to the general public and to physicians, this adverse outcome is rarely mentioned or is attributed solely to reduced calcium absorption. Recent studies investigating micronutrient malabsorption and changes in a wide range of hormones induced by bariatric surgery now indicate that calcium malabsorption is the tip of a formidable iceberg. The current article, part 1 of a 2-part series, reviews the latest research findings confirming that obesity prevalence is skyrocketing and that bariatric surgery causes ongoing, accelerated bone loss. Part 1 also discusses the mechanisms through which the bariatric surgery-induced malabsorption of key nutrients adversely affects bone homeostasis. Part 2 discusses the specific changes seen in bone metabolism after bariatric surgery and reviews current data on the underlying mechanisms, in addition to nutrient malabsorption, which are thought to contribute to bariatric surgery-induced ongoing accelerated bone loss. These processes include mechanical unloading and changes in a wide variety of hormones (eg, leptin, adiponectin, testosterone, estradiol, serotonin, ghrelin, glucagon-like peptide 1, and gastric inhibitory peptide). Also, part 2 covers interventions that may help lessen bariatric surgery-induced bone loss, which are now beginning to appear in the medical literature. Bariatric surgery's adverse effects on bone must be widely recognized and protocols developed to prevent early onset osteoporosis in the recipients of an increasingly utilized

  1. Bariatric diagnostic CT scanning: A radiotherapy perspective

    International Nuclear Information System (INIS)

    Obesity is increasing in the United Kingdom. Equipment available for this patient group including wheelchairs, beds and hoists is becoming more common in the hospital environment; diagnostic imaging equipment that can accommodate bariatric patients has not increased at the same rate. Subsequently these service-users are often unable to receive “gold-standard” cross-sectional imaging within their patient-pathway. This paper highlights how a diagnostic imaging department has utilised wide-bore CT scanning equipment within the radiotherapy setting to ensure an equitable service for all service users. Through literature review and local experience, a standard operating procedure and scanning service has been developed. Areas explored include technical consideration of scanner design; patient positioning; image artefacts and intravenous contrast administration. Also investigated is patient wellbeing incorporating manual handling, respiration and psycho-social needs. Additionally, demonstration of how interprofessional collaboration by diagnostic and radiotherapy radiographers can ensure the best imaging experience and outcome for this patient group. - Highlights: • Rising obesity in the UK has highlighted a shortage of diagnostic imaging facilities. • Large bore CT scanners are the scanner of choice for radiotherapy planning. • Technical capability, manual handling and psycho-social issues have been explored. • Bariatric diagnostic imaging facilitated by inter-professional collaboration

    Full Text Available Obesity, is a chronic, biological, preventable, and treatable disease. The accumulation of fat mass causes physical changes (adiposity, metabolic and hormonal changes due to adipose tissue dysfunction (adiposopathy, and psychological changes. Bariatric endocrinology was conceived from the need to address the neuro-endocrinological derangements that are associated with adiposopathy, and from the need to broaden the scope of the management of its complications. In addition to the well-established metabolic complications of overweight and obesity, adiposopathy leads to hyperinsulinemia, hyperleptinemia, hypoadiponectinemia, dysregulation of gut peptides including GLP-1 and ghrelin, the development of an inflammatory milieu, and the strong risk of vascular disease. Therapy for adiposopathy hinges on effectively lowering the ratio of orexigenic to anorexigenic signals reaching the the hypothalamus and other relevant brain regions, favoring a lower caloric intake. Adiposopathy, overweight and obesity should be treated indefinitely with the specific aims to reduce fat mass for the adiposity complications, and to normalize adipose tissue function for the adiposopathic complications. This paper defines the principles of medical practice in bariatric endocrinology—the treatment of overweight and obesity as means to treat adiposopathy and its accompanying metabolic and hormonal derangements.

Obesity leads to significant systemic disorders, such as hypertension, hypercholesterolemia, hypertriglyceridemia and insulin resistance, and also increases the risk of developing cardiovascular diseases (ischemic heart disease, ischemic stroke), metabolic diseases (type 2 diabetes), certain types of cancer, and degenerative bone disorders (osteoarthritis). Health hazards associated with epidemic of obesity and potential benefits of weight loss have spurred interest in new treatment methods. Bariatric surgical procedures constitute a recognized alternative in cases where conservative management of obesity fails. Several bariatric operations can be distinguished: restrictive procedures, such as adjustable gastric band (AGB) and vertical banded gastroplasty (VBG); predominantly malabsorptive procedures, such as biliopancreatic diversion (BPD), and a combination of both methods, such as Roux-en-Y gastric bypass. The adverse consequences of surgical treatment of obesity include i.a.: intestinal anastomotic leakage, impaired intestinal permeability and internal hernia, dilatation of the stomach, gastrointestinal anastomotic stenosis, marginal ulceration, incisional hernia. Basic knowledge of procedures in the surgical treatment of obesity is of vital importance for the radiologist during evaluation of upper gastrointestinal tract in the early and late postoperative period, allowing correct interpretation of acquired images as well as recognition of typical complications

    Bariatric surgery is recognised as an effective treatment strategy for obese patients with type 2 diabetes mellitus. An increasing number of patients with type 1 diabetes mellitus also suffer with obesity and obesity-associated comorbidities but the role of bariatric and metabolic surgery in this group of patients is unclear. This systematic review investigates published English language scientific literature to understand the results of bariatric surgery in obese patients with type 1 diabetes mellitus. We found that these patients can experience significant weight loss and comorbidity resolution with bariatric surgery. Though most patients also see a decline in total insulin requirement, glycaemic control remains difficult. Most of the patients reported in literature have undergone gastric bypass but data is insufficient to recommend any particular procedure.

  6. Metabolic Bone Disease in the Bariatric Surgery Patient

    Full Text Available Bariatric surgery has proven to be a life-saving measure for some, but for others it has precipitated a plethora of metabolic complications ranging from mild to life-threatening, sometimes to the point of requiring surgical revision. Obesity was previously thought to be bone protective, but this is indeed not the case. Morbidly obese individuals are at risk for metabolic bone disease (MBD due to chronic vitamin D deficiency, inadequate calcium intake, sedentary lifestyle, chronic dieting, underlying chronic diseases, and the use of certain medications used to treat those diseases. After bariatric surgery, the risk for bone-related problems is even greater, owing to severely restricted intake, malabsorption, poor compliance with prescribed supplements, and dramatic weight loss. Patients presenting for bariatric surgery should be evaluated for MBD and receive appropriate presurgical interventions. Furthermore, every patient who has undergone bariatric surgery should receive meticulous lifetime monitoring, as the risk for developing MBD remains ever present.

    Full Text Available Obesity has currently reached epidemic proportions, both in Chile and in the world. This condition is associated to a variety of maternal complications in all stages of the vital cycle and during pregnancy. Medical treatment has not proved successful thus resulting in an increase in bariatric surgery in recent years, even when it is not first line treatment. This literature review aims to report updated results of surgical treatment for obesity before and during pregnancy with respect to fertility, gestational diabetes, pre-eclampsia and pregnancy-induced hypertension. It also looks into the possible effects of surgery on fetal development, and its relation to premature delivery, fetal macrosomy, low birth weight and neural tube defects, as well as effects on maternal and fetal outcomes, mainly in nutrition. Lastly, we suggest some recommendations that arise from this review on the role of contraception, nutrition and time between surgery and pregnancy.

The Centers for Disease Control and Prevention estimates that 68.5% of Americans, including 63.9% of adult women older than 20 years, are overweight (body mass index between 25 kg/m2 and 29.9 kg/m2 or obese (body mass index >30 kg/m2. In light of this, it is not surprising that the rates of bariatric surgery have also been increasing. When considering the metabolic changes associated with both bariatric surgery and contraceptive use, in combination with the unique medical considerations of obese women, it is indisputable that clear guidelines are needed when counseling obese patients of reproductive age after bariatric surgery. In this literature review, we focus on depot medroxyprogesterone acetate (DMPA and the implications of its use in obese women, preweight and postweight loss following bariatric surgery. Both DMPA use and bariatric surgery are known to cause bone loss, but it is still unclear whether there is an additive effect of the two factors on bone loss and whether either of these factors directly leads to an increased risk of bone fracture. The current consensus guidelines do not impose a restriction on the use of DMPA after bariatric surgery. DMPA use is associated with weight gain, and it is unclear whether weight loss blunting occurs with the use of DMPA after bariatric surgery. Prior studies had demonstrated an association with weight gain in adolescents, and therefore, those prescribing DMPA use after bariatric surgery in adolescents should proceed with caution. Adult women do not have a similar response to the use of DMPA. DMPA use has rarely been associated with increased risk of venous thromboembolism (VTE. The

  10. Persistently High Hip Circumference after Bariatric Surgery Is a Major Hurdle to Successful Hip Replacement

    2014-01-01

    Full Text Available The prevalence of class III obesity (BMI≥40 kg/m2 in black women is 18%. As class III obesity leads to hip joint deterioration, black women frequently present for orthopedic care. Weight loss associated with bariatric surgery should lead to enhanced success of hip replacements. However, we present a case of a black woman who underwent Roux-en-Y gastric bypass with the expectation that weight loss would make her a better surgical candidate for hip replacement. Her gastric bypass was successful as her BMI declined from 52.0 kg/m2 to 33.7 kg/m2. However, her hip circumference after weight loss remained persistently high. Therefore, at surgery the soft tissue tunnel geometry presented major challenges. Tunnel depth and immobility of the soft tissue interfered with retractor placement, tissue reflection, and surgical access to the acetabulum. Therefore a traditional cup placement could not be achieved. Instead, a hemiarthroplasty was performed. After surgery her pain and reliance on external support decreased. But her functional independence never improved. This case demonstrates that a lower BMI after bariatric surgery may improve the metabolic profile and decrease anesthesia risk, but the success of total hip arthroplasties remains problematic if fat mass in the operative field (i.e., high hip circumference remains high.

    Obesity in women of reproductive age is a serious concern regarding reproductive health. In many cases of infertility in obese women, reduction of body weight may lead to spontaneous pregnancy, without the need for more specific methods of treatment. Bariatric surgery is safe and is the most effective method for body weight reduction in obese and very obese patients. In practice there are two bariatric techniques; gastric banding, which leads to weight loss through intake restriction, and gastric bypass, leads to weight loss through food malabsorption. Gastric bypass surgery (the more frequently performed procedure), in most cases, leads to changes in eating habits and may result in vomiting, diarrhea and rapid body mass reduction. There are reliable data describing the continuous increase in the number of women who are trying to conceive, or are already pregnant, following bariatric surgery. Most medical specialists advise women to avoid pregnancy within 12-18 months after bariatric surgery. This allows for time to recover sufficiency from the decreased absorption of nutrients caused by the bariatric surgery. During this period there is a need for the use of reliable contraception. As there is a risk for malabsorption of hormones taken orally, the combined and progestogen-only pills are contraindicated, and displaced by non-oral hormonal contraception or non-hormonal methods, including intrauterine devices and condoms.

    Full Text Available Abstract Background Bariatric surgery is the only procedure that has significant results in weight loss and improvements in medical comorbidities in morbid obese patients. Severely obese patients are also associated with a higher prevalence of psychiatric disorders and poor quality of life. Objective To evaluate specific areas of psychopathology in individuals undergoing bariatric surgery. Methods A review of the literature was conducted from January 2002 to March 2014 by researching PubMed database using the following query: “morbid AND obesity AND bariatric AND surgery AND (psychiatry OR psychology”. Results Overall improvements in eating behaviors, mood disorders and body image are reported after bariatric surgery, and the mechanism is not enlightened. Risk of suicide and consumption of substances of abuse, especially alcohol, after gastric bypass surgery are problems that clinicians must be aware. Discussion Bariatric patients should be monitored after surgery to identify who did not show the expected benefits postoperatively and the ones who develop psychiatric symptoms after an initial positive response.

    Bariatric surgery is an effective intervention in the treatment of obesity, but lifestyle and diet should be monitored after this procedure to ensure success. The Bariatric Food Pyramid was created basing on long-term nutritional care that proposes a standard of healthy living and eating habits considering gastric capacity and specific nutritional needs. The purpose of the current study is to evaluate the life habits and diet quality of patients who have undergone bariatric surgery (who have been recovering for at least 6 months) based on the specific food pyramid. Retrospective data analysis was performed using medical records of patients who had been followed for at least 6 months after bariatric surgery. The following data were collected from patient records: age, gender, education level (years), BMI (preoperative and postoperative), percentage of excess weight loss (EWL) relative to the time of surgery, frequency of physical activity, use of nutritional supplements, usual dietary intake history, and fluid intake. Results were analyzed using descriptive statistics. We evaluated 172 patient records. In this study, there was a low prevalence of physical activity, use of vitamin-mineral supplements, and water intake. There also was low consumption of protein, fruit, vegetables, and vegetable oils. In addition, intake of carbohydrates, sugars, and fats were higher than the recommendations established by the pyramid. The results indicate that patients who have undergone bariatric surgery have an inadequate diet according to food evaluation with the specific pyramid. In the long term, this may lead to weight gain and vitamin and mineral deficiencies.

    Understanding the technical constructs of bariatric surgery is important to the treating endoscopist to maximize effective endoluminal therapy. Post-operative complication rates vary widely based on the complication of interest, and have been reported to be as high as 68% following adjustable gastric banding. Similarly, there is a wide range of presenting symptoms for post-operative bariatric complications, including abdominal pain, nausea and vomiting, dysphagia, gastrointestinal hemorrhage, and weight regain, all of which may provoke an endoscopic assessment. Bleeding and anastomotic leak are considered to be early ( 30 d) complications. Treatment of complications in the immediate post-operative period may require unique considerations. Endoluminal therapies serve as adjuncts to surgical and radiographic procedures. This review aims to summarize the spectrum and efficacy of endoscopic management of post-operative bariatric complications. PMID:27668069

    2013-01-01

    Full Text Available Achieving optimal weight outcomes for patients with obesity is important to the management of their chronic disease. All interventions present risks for weight regain. Bariatric surgery is the most efficacious treatment, producing greater weight losses that are sustained over more time compared to lifestyle interventions. However, approximately 20–30% of patients do not achieve successful weight outcomes, and patients may experience a regain of 20–25% of their lost weight. This paper reviews several factors that influence weight regain after bariatric surgery, including type of surgery, food tolerance, energy requirements, drivers to eat, errors in estimating intake, adherence, food and beverage choices, and patient knowledge. A comprehensive multidisciplinary approach can provide the best care for patients with weight regain. Nutrition care by a registered dietitian is recommended for all bariatric surgery patients. Nutrition diagnoses and interventions are discussed. Regular monitoring of weight status and early intervention may help prevent significant weight regain.

    Full Text Available Guidelines for enhanced recovery after surgery (ERAS are widely used and their efficiency was clearly demonstrated by numerous studies. Number of publications on this topic in bariatric surgery is significantly lower compared with other fields of surgery. However, the data accumulated allow to compose recommendations based on studies with high level of evidence. Authors review existing methods of enhanced recovery in their implementation into bariatric surgery. Enhanced recovery methods can be used to optimize all stages of perioperative care and include data on preoperative preparation, maintenance of electrolyte balance, prevention of postoperative nausea and vomiting, sufficient analgesia and safe discharge form hospital. Suggested guidelines for bariatric surgery are implied to be used by a multidisciplinary team.

    In the UK, 62% of the population are now described as being either overweight or obese. People with weight-management issues are more likely to suffer from cardiovascular disease and diabetes, as well as having an increased risk of cancer, including bowel cancer. Following the initial National Institute for Health and Care Excellence guidance in 2006, revised in 2014, health professionals have a more proactive role in identifying people with weight-management issues and supporting them to achieve a weight that helps reduce their health risks. This includes referrals to bariatric surgeons for consideration for surgery if appropriate. One particular surgical procedure, the Roux-en-Y, is not reversible and alters the capacity of the stomach and function of the small bowel in order to achieve weight loss. Using a case study, this article will highlight the role of the stoma nurse in managing a patient, who previously had a Roux-en-Y procedure for weight loss and subsequently needed formation of a loop ileostomy after surgery for bowel cancer.

    Full Text Available The plague of obesity afflicts an increasing group of people. Moreover type 2 diabetes, which is the most serious illness accompanying excessive weight, is becoming more and more common. Traditional methods of obesity treatment, such as diet and physical exercise, fail. This applies especially to people with class III obesity. The only successful way of treating obesity in their case is bariatric surgery. There are three types of bariatric surgery: restrictive procedures (reducing stomach volume, malabsorptive procedures, and mixed procedures, which combine both methods. In spite of the risk connected with the surgery and complications after it, bariatric procedures are advised to patients with class III obesity and class II with an accompanying illness which increases the probability of death. It has been proved that bariatric surgery not only eliminates obesity but also very frequently (in 90�0of cases leads to the remission of type 2 diabetes. Moreover, the remission occurs very fast – it takes place a long time before the patients reduce their weight, even within a few days after surgery. Detailed studies have shown that the remission of diabetes is caused mostly by the change of the gastro-intestinal hormones’ profile, resulting from the surgery. These hormones include GLP-1, GIP, peptide YY, ghrelin and oxyntomodulin. Additionally, the change of the amount of adipose tissue after the surgery influences the level of adipokines, i.e. the hormones of the adipose tissue, among which the most important are leptin, adiponectin and resistin. Thus, bariatric surgery not only changes the shape of the gastrointestinal tract but it also modulates the hormonal activity. Bariatric surgery is considered as therapy not only for the obese but also for diabetic patients.

    Bariatric surgery results in durable weight loss and improved comorbidities. The objectives of this study were to examine the efficacy of gastric bypass in reducing comorbid burden and improving metabolic status among morbidly obese adolescents. The medical records of 15 gastric bypass patients were retrospectively reviewed. Changes in metabolic markers were determined at baseline, 1 and 2 years post-operatively. Comparative analysis demonstrated significant improvement in weight, BMI, insulin, HbA1C, C-peptide, %B, %S, IR, cholesterol, percentile cholesterol, TG, percentile TG, HDL, percentile HDL, LDL, percentile LDL, and VLDL. Results support bariatric surgery as a treatment for morbidly obese adolescents with comorbidities.

    Bariatric surgery has considerably developed during the last 20 years in Belgium. The increase of prevalence of the morbid obesity and the development of multiple surgical procedures widened the spectrum of treatment. If a rigorous selection and a multidisciplinary approach of the patients are inescapable, the various decision-making algorithms plunge the practitioner into a certain confusion. The purpose of this paper is to clarify the advantages and the inconveniences of the different surgical treatments in light of the evolution of the principles and the objective results of the literature. Among the techniques proven and validated in the long run, one can mention the Silastic Ring Vertical Gastroplasty according to Mac Lean by minilaparotomy, the laparoscopic adjustable ring and the more recent gastric by pass. The evaluation of laparoscopic sleeve gastrectomy, and of duodenal switch is on course. The bilio-pancreatic by-pass according to Scopinaro remains strongly controversed. A meta-analysis of the literature confirms the success of the gastric bypass. Regarding to the long term follow-up, the adjustable gastric banding deceives. The sleeve gastrectomy should be analyzed in the long term. The preliminary results of a epidemiologic and financial study within a private hospital of Brussels reveals that the cost effective ratio is in favor the Silastic Ring Vertical Gastroplasty and the laparoscopic adjustable banding, as well in terms of public health support than the charge for the private insurance and the patient. The projection beyond 5 years reverses the tendency to plead in favor of the gastric by-pass. First with the hit-parade of comfort, food diversification, tolerance, gastro-esophageal reflux, and undoubtedly of the rate of recurrence, it supplants the others techniques for sweet eaters. The volume eaters can profit from a sleeve gastrectomy which undoubtedly supplants the Silastic Ring Vertical Gastroplasty responsible for late annular stenoses and

    Bariatric surgery is most commonly carried out in women of childbearing age. Whilst fertility rates are improved, pregnancy following bariatric surgery poses several challenges. Whilst rates of many adverse maternal and foetal outcomes in obese women are reduced after bariatric surgery, pregnancy is best avoided for 12-24 months to reduce the potential risk of intrauterine growth retardation. Dumping syndromes are common after bariatric surgery and can present diagnostic and therapeutic challenges in pregnancy. Early dumping occurs due to osmotic fluid shifts resulting from rapid gastrointestinal food transit, whilst late dumping is characterized by a hyperinsulinemic response to rapid absorption of simple carbohydrates. Dietary measures are the mainstay of management of dumping syndromes but pharmacotherapy may sometimes become necessary. Acarbose is the least hazardous pharmacological option for the management of postprandial hypoglycemia in pregnancy. Nutrient deficiencies may vary depending on the type of surgery; it is important to optimize the nutritional status of women prior to and during pregnancy. Dietary management should include adequate protein and calorie intake and supplementation of vitamins and micronutrients. A high clinical index of suspicion is required for early diagnosis of surgical complications of prior weight loss procedures during pregnancy, including small bowel obstruction, internal hernias, gastric band erosion or migration and cholelithiasis.

    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/m(2)) should receive counseling on diet, lifestyle, exercise and goals for weight management. Individuals with BMI ≥ 40 kg/m(2) and those with BMI > 35 kg/m(2) 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.

    An emerging literature has illuminated an important link between Type 2 diabetes mellitus (DM) and binge eating disorder (BED) within obese cohorts. However, prior work has not examined this relationship specifically in a weight loss surgery (WLS) sample or fully explored potential psychosocial factors associated with this co-occurrence. Therefore, the present investigation sought to identify socio-demographic (i.e. age, education, BMI, ethnicity, gender, age of obesity onset) and psychological (i.e. depressive symptoms, hedonic hunger/food locus of control beliefs, severity of binge eating-related cognitions) correlates of the co-occurrence of Type 2 DM and BED among bariatric surgery candidates. An archival sample of 488 patients seeking surgical treatment for clinical obesity completed a standard battery of pre-operative psychosocial measures. The presence of BED was evaluated using a semi-structured clinical interview based on the DSM-IV TR (APA, 2000) and was further corroborated by responses on the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R; Spitzer, Yanovski, & Marcus, 1993). Results indicated that 8.2% of the sample was classified as having both Type 2 DM and BED concurrently. A multivariate logistic regression model revealed that in addition to other psychological (e.g., binge eating-related cognitions, hedonic hunger) and demographic variables (i.e. male gender), African American ethnicity (OR=3.3: 1.41-7.73) was a particularly robust indicator of comorbid status. Findings support and extend previous health disparity research urging greater attention to the needs of traditionally underserved, at-risk populations seeking treatment for obesity complicated by dysregulated eating and metabolism. Additionally, these preliminary results underscore the relevance of considering the potential benefits of providing quality comprehensive pre- and post-operative psychological care among bariatric patients towards optimizing both short- and long

    Obesity is one of the leading causes of health related disorder and has reached epidemic proportions not only in developed nations but also in developing countries like India. Bariatric surgery has become a popular alternative for obese women planning pregnancy. A multidisciplinary approach involving the obstetrician, the bariatric surgeon and the nutritionist is required to manage pregnancy following bariatric surgery. Early consultation should be done to determine baseline nutritional status and the importance of regular check-ups must be explained. Nutritional supplementation should be tailored to the patient's status and the type of bariatric surgery performed. PMID:26672514

    Full Text Available Atrial fibrillation (AF is a common and refractory arrhythmia. Prevalence of AF increases with age. Asymptomatic AF is a state of asymptomatic episodes of arrhythmia and its exact prevalence remains unknown. Ablation and therapy with antiarrhythmic agents may predispose to asymptomatic AF. Detection of silent AF is crucial for prevention of ischaemic stroke. Progress in continuous ECG monitoring by Holter ECG, telemetry methods or implantable devices can provide a useful tools for identifying silent AF. Simple screening procedures like pulse examination and ambulatory ECG may be helpful in arrhythmia detection and logically – ischemic stroke prevention.

    The prevalence of kidney stones is increasing worldwide. Asymptomatic non-obstructing kidney stones are increasingly detected as an incidental finding on radiologic imaging, which has been performed more frequently over the last decades. Beside the current interventional treatment modalities such as extracorporeal shockwave lithotripsy (ESWL), ureterorenoscopy (URS) and percutaneous nephrolithotomy (PNL), active surveillance of asymptomatic kidney stones has been a focus of discussion lately, not only for attending physicians, but even more so for patients. The current German and European guidelines recommend active surveillance for patients with asymptomatic kidney stones if no interventional therapy is mandatory because of pain or medical factors. Herein we review the current literature on risks and benefits of active surveillance of asymptomatic non-obstructing kidney stones. PMID:26378390

    Full Text Available Obesity is a worldwide problem with numerous associated health problems. The number of patients eligible for surgery outnumber surgical capacity and so patients need to be prioritised based on their obesity- related health burden and comorbidities. Weight loss as a result of bariatric surgery is significant and maintained in the long term. In addition to weight loss, patient health improves in terms of metabolic, macrovascular, and microvascular disease. As a result, quality of life is better, along with psychosocial wellbeing. Bariatric surgery is associated with a relatively low number of complications and appears to result in a reduction in mortality risk due to the resolution of comorbidities. Hence, surgery can now be routinely considered as an adjunct to medical therapy in the management of obesity.

    Full Text Available Since more than half of the population in America falls under the category of obesity, scientists have discovered a surgical technique to reduce the weight of the obese patients. Bariatric surgery or gastric bypass surgery is a procedure that has been successful in reducing the weight for obese people. This technique requires a permanent gastric bypass (Roux-en-Y where part of the stomach and duodenum is removed. Since the size of the stomach is reduced to 20% of its original size along with the removal of duodenum – this may lead to improper absorption of several vitamins and minerals. This review showed that several vitamins and mineral deficiencies are observed in patients, post-operative bariatric surgery. Thiamin, folate, and B12 deficiencies were most commonly observed, and Vitamin A, D, C and B6 deficiencies were also seen in some cases. Iron and calcium deficiencies were also reported by some of the studies.

    Communication between the bariatric surgeon and the obese patient is very important as it influences the expectations of patients with regard to surgery, aim of the surgery and the understanding of the mechanisms of failure of surgery. Furthermore, the incidence of certain psychopathology in these patients makes it necessary for the surgeon to have the ability to communicate to the patient the need for motivation and the maintenance of healthy life habits. Although the topic is subjective, in this article we review several useful recommendations to optimize communication before and after surgery. Finally, we emphasize the need to create workshops to train the bariatric surgeon in these issues that we consider so important. PMID:25912163

    Full Text Available Overweight and obesity represent major risk factors for diabetes and related metabolic diseases. Obesity is associated with a chronic and progressive inflammatory response leading to the development of insulin resistance and type 2 diabetes (T2D mellitus, although the precise mechanism mediating this inflammatory process remains poorly understood. The most effective intervention for the treatment of obesity, bariatric surgery, leads to glucose normalization and remission of T2D. Recent work in both clinical studies and animal models supports bile acids (BAs as key mediators of these effects. BAs are involved in lipid and glucose homeostasis primarily via the farnesoid X receptor (FXR transcription factor. BAs are also involved in regulating genes involved in inflammation, obesity, and lipid metabolism. Here, we review the novel role of BAs in bariatric surgery and the intersection between BAs and immune, obesity, weight loss, and lipid metabolism genes.

  18. The Night Eating Syndrome (NES) in Bariatric Surgery Patients.

    2015-11-01

    The night eating syndrome (NES) has been included into the Diagnostic and Statistical Manual of Mental Disorders 5 as an example of an 'other-specified feeding or eating disorder'. The prevalence of NES has found to be higher in obese populations than in the general population and seems to rise with increasing body mass index. Recent studies suggest a prevalence of 2%-20% in bariatric surgery samples. Given that the core feature of this eating disorder may involve a shift in the circadian pattern of eating that disrupts sleep, and not the ingestion of objectively large amounts of food, it is a pattern that can continue after bariatric surgery. Nonetheless, symptoms of NES appear to decrease after weight loss surgery, and there is no evidence that pre-surgery NES negatively impacts weight loss following surgery. Prospective and longitudinal studies of the course of night eating symptoms are warranted using clear criteria and standardized assessment instruments.

    The obesity epidemic is also an economic tragedy. This analysis evaluates the economic effects and the potential to improve the well-being of both individual and societal wealth. Econometric techniques should carefully assess the degree to which obesity affects declines in business output, employment, income, and tax revenues at the regional and national levels. Microeconomics assesses lost productivity and associated wages and profit. Macroeconomics assesses trends associated with employment, inflation, interest rates, money supply, and output. To decrease the adverse economic consequences of the obesity epidemic, policy makers must emphasize bariatric surgery as a cost-effective option for qualified patients. Early intervention, education, and tax rebates for obese individuals who undergo bariatric surgery and for medical centers and doctors would likely have positive economic effects on the whole economy in a few years.

    Objectives The aim of this study was to investigate the effects of bariatric surgery on small artery function and the mechanisms underlying this. Background In lean healthy humans, perivascular adipose tissue (PVAT) exerts an anticontractile effect on adjacent small arteries, but this is lost in obesity-associated conditions such as the metabolic syndrome and type II diabetes where there is evidence of adipocyte inflammation and increased oxidative stress. Methods Segments of small subcutaneous artery and perivascular fat were harvested from severely obese individuals before (n = 20) and 6 months after bariatric surgery (n = 15). Small artery contractile function was examined in vitro with wire myography, and perivascular adipose tissue (PVAT) morphology was assessed with immunohistochemistry. Results The anticontractile activity of PVAT was lost in obese patients before surgery when compared with healthy volunteers and was restored 6 months after bariatric surgery. In vitro protocols with superoxide dismutase and catalase rescued PVAT anticontractile function in tissue from obese individuals before surgery. The improvement in anticontractile function after surgery was accompanied by improvements in insulin sensitivity, serum glycemic indexes, inflammatory cytokines, adipokine profile, and systolic blood pressure together with increased PVAT adiponectin and nitric oxide bioavailability and reduced macrophage infiltration and inflammation. These changes were observed despite the patients remaining severely obese. Conclusions Bariatric surgery and its attendant improvements in weight, blood pressure, inflammation, and metabolism collectively reverse the obesity-induced alteration to PVAT anticontractile function. This reversal is attributable to reductions in local adipose inflammation and oxidative stress with improved adiponectin and nitric oxide bioavailability. PMID:23665100

    Severe obesity is associated with increased risk of kidney disease. Whether bariatric surgery reduces the risk of adverse kidney outcomes is uncertain. To resolve this we compared the risk of estimated glomerular filtration rate (eGFR) decline of ≥30% and doubling of serum creatinine or end-stage renal disease (ESRD) in 985 patients who underwent bariatric surgery with 985 patients who did not undergo such surgery. Patients were matched on demographics, baseline body mass index, eGFR, comorbidities, and previous nutrition clinic use. Mean age was 45 years, 97% were white, 80% were female, and 33% had baseline eGFR surgery group compared with 1.4 kg in the matched cohort. Over a median follow-up of 4.4 years, 85 surgery patients had an eGFR decline of ≥30% (22 had doubling of serum creatinine/ESRD). Over a median follow-up of 3.8 years, 177 patients in the matched cohort had an eGFR decline of ≥30% (50 had doubling of serum creatinine/ESRD). In adjusted analysis, bariatric surgery patients had a significant 58% lower risk for an eGFR decline of ≥30% (hazard ratio 0.42, 95% confidence interval 0.32-0.55) and 57% lower risk of doubling of serum creatinine or ESRD (hazard ratio 0.43, 95% confidence interval: 0.26-0.71) compared with the matched cohort. Results were generally consistent among subgroups of patients with and without eGFR bariatric surgery may be an option to prevent kidney function decline in severely obese individuals.

This is an unusual complication which determines a significant functional limitation, mainly because of foot drop, and its presence may be a hallmark of excessive and rapid weight loss. We discuss possible pathogenic mechanisms and therapeutic options, and we emphasize the important role of an adequate nutritional management, in order to avoid the need for a surgical nerve decompression.

    To investigate the utility of acoustic radiation force impulse (ARFI) imaging, with the determination of shear wave velocity (SWV), to differentiate non-alcoholic fatty liver disease (NAFLD) from non-alcoholic steatohepatitis (NASH) in patients with morbid obesity before bariatric surgery. Thirty-two patients with morbid obesity were evaluated with ARFI and conventional ultrasound before bariatric surgery. The ARFI and ultrasound results were compared with liver biopsy findings, which is the reference standard. The patients were classed according to their histological findings into three groups: group A, simple steatosis; group B, inflammation; and group C, fibrosis. The median SWV was 1.57 {+-} 0.79 m/s. Hepatic alterations were observed in the histopathological findings for all the patients in the study (100 %), with the results of the laboratory tests proving normal. Differences in SWV were also observed between groups A, B and C: 1.34 {+-} 0.90 m/s, 1.55 {+-} 0.79 m/s and 1.86 {+-} 0.75 m/s (P < 0.001), respectively. The Az for differentiating NAFLD from NASH or fibrosis was 0.899 (optimal cut-off value 1.3 m/s; sensitivity 85 %; specificity 83.3 %). The ARFI technique is a useful diagnostic tool for differentiating NAFLD from NASH in asymptomatic patients with morbid obesity. (orig.)

  7. The Impact of Bariatric Surgery on Psychological Health

    2013-01-01

    Full Text Available Obesity is associated with a relatively high prevalence of psychopathological conditions, which may have a significant negative impact on the quality of life. Bariatric surgery is an effective intervention in the morbidly obese to achieve marked weight loss and improve physical comorbidities, yet its impact on psychological health has yet to be determined. A review of the literature identified a trend suggesting improvements in psychological health after bariatric surgery. Majority of mental health gain is likely attributed to weight loss and resultant gains in body image, self-esteem, and self-concept; however, other important factors contributing to postoperative mental health include a patient’s sense of taking control of his/her life and support from health care staff. Preoperative psychological health also plays an important role. In addition, the literature suggests similar benefit in the obese pediatric population. However, not all patients report psychological benefits after bariatric surgery. Some patients continue to struggle with weight loss, maintenance and regain, and resulting body image dissatisfaction. Severe preoperative psychopathology and patient expectation that life will dramatically change after surgery can also negatively impact psychological health after surgery. The health care team must address these issues in the perioperative period to maximize mental health gains after surgery.

  8. [Bariatric and plastic surgery in obese adolescents: an alternative treatment].

    2014-06-01

    The increased frequency of extreme forms of obesity in adolescents and the disappointing results of conventional treatments are now leading pediatricians to consider bariatric or cosmetic surgery as the only real long-term effective therapeutic alternative. The two main techniques currently used for bariatric surgery in adolescents are gastric bypass and adjustable gastric banding. Whatever the technique, weight loss is significant with improvement of comorbidities and quality of life. In addition, the complications are identical to those in adults and equally frequent. However, because of the particularities of this age, caution is still required. Adolescence is indeed characterized by specific nutritional needs, but also changes in body image in which surgery could have a negative effect. Currently, all obese teenagers making a request for bariatric surgery should have a comprehensive assessment with global care for at least 6 months. The indication is then discussed on a case-by-case basis by multidisciplinary teams and experts. To date, the type of surgery (gastric banding, gastric sleeve, or bypass) is still widely discussed. Based on experience with adults, we believe that gastric sleeve and bypass should be preferred. In addition, obesity in adolescents almost always involves psychosocial consequences, while somatic complications are rare. Thus, the care of adipo- or gynecomastia, abdominal fat excess, and concealed penis is essential and therefore justifies cosmetic surgery.

    The epidemic in obesity has led to an increase in number of so called bariatric procedures. Doctors are less comfortable managing an obese patient after bariatric surgery. Peri-operative mortality is less than 1%. The specific feature in the obese patient is that the classical signs of peritoneal irritation are never present as there is no abdominal wall and therefore no guarding or rigidity. Simple post-operative tachycardia in obese patients should be taken seriously as it is a WARNING SIGNAL. The most common complication after surgery is peritonitis due to anastomotic fistula formation. This occurs typically as an early complication within the first 10 days post-operatively and has an incidence of 1-6% after gastric bypass and 3-7% after sleeve gastrectomy. Post-operative malnutrition is extremely rare after restrictive surgery (ring, sleeve gastrectomy) although may occur after malabsorbative surgery (bypass, biliary pancreatic shunt) and is due to the restriction and change in absorption. Prophylactic cholecystectomy is not routinely carried out during the same procedure as the bypass. Superior mesenteric vein thrombosis after bariatric surgery is a diagnosis which should be considered in the presence of any postoperative abdominal pain. Initially a first etiological assessment is performed (measurement of antithrombin III and of protein C and protein S, testing for activated protein C resistance). If the least doubt is present, a medical or surgical consultation should be requested with a specialist practitioner in the management of obese patients as death rates increase with delayed diagnosis.

    2016-07-01

    Bariatric/metabolic surgery is currently the only effective long-term treatment for morbid obesity- and obesity-related diseases such as diabetes, heart disease, hypertension, obstructive sleep apnea, and dyslipidemia. In addition, bariatric/metabolic surgery has been shown to significantly reduce the incidence of diabetes and cancer and prolong life when compared to non-surgical therapies. However, as obesity is a chronic disease, recidivism of weight and comorbid conditions can occur. In addition, the surgical construct can lead to long-term consequences such as marginal ulceration, bowel obstruction, reflux, and nutritional deficiencies. Despite these drawbacks, prospective randomized controlled studies and long-term longitudinal population-based comparative studies greatly favor surgical intervention as opposed to traditional lifestyle, diet, and exercise programs. Revisional surgery can be quite complex and technically challenging and may offer the patient a wide variety of solutions for treatment of weight recidivism and complications after primary operations. Given the paucity of high quality published data, we have endeavored to provide indications for revisions after bariatric surgery. PMID:27221504

  17. Asymptomatic cerebral hemorrhage detected by MRI

    International Nuclear Information System (INIS)

    Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule. The secondary asymptomatic hemorrhage were due to AVM and angiomas in the frontal cortex, thalamus and pons. (author)

    Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule. The secondary asymptomatic hemorrhage were due to AVM and angiomas in the frontal cortex, thalamus and pons. (author).

    Full Text Available "nPregnant women are at increased risk for urinary tract infection (UTI but in many cases infection is asymptomatic. This study was performed to determine the incidence of asymptomatic bacteriuria and pyuria in pregnant women. A total of 86 pregnant women during first trimester and 56 nonpregnant women were evaluated. All subjects were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine samples were collected for both groups. Urine samples were examined microscopically and were cultured. Bacteriological examination revealed asymptomatic bacteriuria in 25 (29.1% and 3 (5.4% of the study group and controls, respectively (P < 0.05. Microscopic analysis of urine revealed pyuria in 18 (20.9% and 3 (5.4% of the study group and controls, respectively (P < 0.05. In study group, Escherichia coli were found in 20%, Staphylococcus epidermidis in 36%, Staphylococcus haemolyticus in 12%, streptococcus group D in 12%, Staphylococcus saprophyticus in 12% and Proteus mirabilis in 8%. In control group, E. coli were found in 33.3% and S. epidermidis in 66.7%. Our results show that the incidence of asymptomatic bacteriuria is significantly higher in pregnant women than nonpregnant women. The main finding in the present study was that 29.1% of the pregnant women who were in first trimester had asymptomatic bacteriuria which is much higher than figures reported from other countries. The use of microscopic urinanalysis was not an effective method of detecting asymptomatic bacteriuria and urine culture is necessary for screening these pregnant women.

    Full Text Available Obesity and its relation to quality of life are multifaceted. The purpose of this paper was to contribute evidence to support a framework for understanding the impact of obesity on quality of life in 42 morbidly obese subjects considering a wide number of potential determinants. A model of weight-related quality of life (WRQL was developed based on the Wilson-Cleary model, considering subjects' weight characteristics, arterial oxygen pressure (PaO2, walking capacity (6-minute walk test, 6MWT, health-related quality of life (HRQL; Physical and Mental Component Summaries of the SF-36 PCS/MCS, and WRQL. The model of WRQL was tested with linear regressions and a path analysis, which showed that as PaO2 at rest increased 6MWT increased. 6MWT was positively associated with the PCS, which in turn was positively related to WRQL along with the MCS. The model showed good fit and explained 38% of the variance in WRQL.

    Full Text Available Endoscopic treatment has generally been accepted in the management of bleeding esophageal varices. Both the control of acute variceal bleeding and elective variceal eradication to prevent recurrent bleeding can be achieved via endoscopic methods. In contrast to acute and elective treatment, the role of endoscopic therapy in asymptomatic patients who have never had variceal bleeding remains controversial because of the rather disappointing results obtained from prophylactic sclerotherapy. Most published randomized controlled trials showed that prophylactic sclerotherapy had no effect on survival. In some studies, neither survival rate nor bleeding risk was improved. In this article, the author champions the view that asymptomatic esophageal varices should be endoscopically treated.

    While the demand for bariatric surgery is increasing, hospital capacity remains limited. The ERABS (Enhanced Recovery After Bariatric Surgery) protocol has been implemented in a number of bariatric centers. We retrospectively compared the operating room logistics and postoperative complications between pre-ERABS and ERABS periods in an academic hospital. The primary endpoint was the length of stay in hospital. The secondary endpoints were turnover times-the time required for preparing the operating room for the next case, induction time (from induction of anesthesia until a patient is ready for surgery), surgical time (duration of surgery), procedure time (duration of stay in the operating room), and the incidence of re-admissions, re-operations and complications during admission and within 30 days after surgery. Of a total of 374 patients, 228 and 146 received surgery following the pre-ERABS and ERABS protocols, respectively. The length of hospital stay was significantly shortened from 3.7 (95 % confidence interval [CI] 3.1-4.7) days to 2.1 (95 % CI 1.6-2.6) days (P surgery, respectively (P < 0.001 for both), by introducing the ERABS protocol. Induction times were reduced from 15.2 (95 % CI 14.3-16.1) min to 12.5 (95 % CI 11.7-13.3) min (P < 0.001).Turnover times were shortened significantly from 38 (95 % CI 44-32) min to 11 (95 % CI 8-14) min. The incidence of re-operations, re-admissions and complications did not change.

    Background Obesity is an independent risk factor of development and progression of chronic kidney disease (CKD). Data on the benefits of bariatric surgery in obese patients with impaired kidney function have been conflicting. Objective To explore whether there is improvement in glomerular filtration rate (GFR), proteinuria or albuminuria after bariatric surgery. Methods We comprehensively searched the databases of MEDLINE, Embase, web of science and Cochrane for randomized, controlled trials and observational studies that examined bariatric surgery in obese subjects with impaired kidney function. Outcomes included the pre- and post-bariatric surgery GFR, proteinuria and albuminuria. In obese patients with hyperfiltration, we draw conclusions from studies using measured GFR (inulin or iothalamate clearance) unadjusted for BSA only. Study quality was evaluated using the Newcastle-Ottawa Scale. Results 32 observational studies met our inclusion criteria, and 30 studies were included in the meta-analysis. No matter in dichotomous data or in dichotomous data, there were statistically significant reduction in hyperfiltration, albuminuria and proteinuria after bariatric surgery. Limitations The main limitation of this meta-analysis is the lack of randomized controlled trials (RCTs). Another limitation is the lack of long-term follow-up. Conclusions Bariatric surgery could prevent further decline in renal function by reducing proteinuria, albuminuria and improving glomerular hyperfiltration in obese patients with impaired renal function. However, whether bariatric surgery reverses CKD or delays ESRD progression is still in question, large, randomized prospective studies with a longer follow-up are needed. PMID:27701452

    This study aims to review the obesity literature in order to assess the impact of bariatric surgery on quality of life and the between-study variation by examining the standardized mean magnitude of effect in change in the levels of quality of life. The following databases EMBASE, PubMed, PsycINFO, CINAHL, the Cochrane Library and Web of Science were systematically searched for studies examining change in quality of life in adults receiving bariatric surgery for obesity. Seventy-two studies were included with a total of 9,433 participants treated for obesity with bariatric surgery. The average impact of bariatric surgery on quality of life corresponded to an effect size of 0.88 (95% CI: 0.80-0.96), indicating that bariatric surgery has a significant positive influence on quality of life in general. The impact varied considerably across studies with bariatric surgery showing a significantly greater positive influence on physical quality of life compared to mental quality of life. Bariatric surgery is effective in improving quality of life, especially when looking at physical well-being. Greater focus on the psychological well-being of the person undergoing surgery for obesity may lead to a better post-surgery prognosis for more people.

    Temperament and personality traits can serve as both risk factors as well as protective factors in the development of morbid obesity. In the present review, we present an overview of studies focusing on the relationship between temperament/personality and morbid obesity in pre-operative and postoperative bariatric surgery patients. We consider studies that focus on both a categorical and dimensional point of view on temperament/personality, as well as studies based on cross-sectional and longitudinal designs. Finally, we will integrate the research findings, discuss the implications for assessment and treatment and formulate suggestions for future research.

    Background Bariatric surgery is one of the few effective treatments for morbid obesity but the weight loss and other health related outcomes for this procedure in large, diverse adolescent patient populations are not well characterized. Objective To analyze the prospective Bariatric Outcomes Longitudinal Database (BOLD) to determine the weight loss and health related outcomes in adolescents. Setting BOLD data is collected from 423 surgeons at 360 facilities in the United States. Methods Main outcome measures included anthropometric and comorbidity status at baseline (n=890) and at 3 (n=786), 6 (n=541), and 12 (n=259) months after surgery. Adolescents (75% female; 68% non-Hispanic white, 14% Hispanic, 11% non-Hispanic black, and 6% other) age 11-to-19 years were included in the analyses. Results The overall one year mean weight loss for those who underwent gastric bypass surgery was more than twice that of those who underwent adjustable gastric band surgery (48.6 kg versus 20 kg, P<0.001). Similar results were found for all other anthropometric changes and comparisons over one year between surgery types (P<0.001). In general, gastric bypass patients reported more improvement versus adjustable gastric band patients in comorbidities one year after surgery. There were a total of 45 readmissions among gastric bypass patients and 10 among adjustable gastric band patients with 29 and 8 reoperations required, respectively. Conclusions Weight loss at 3-, 6-, and 12-months after surgery is approximately double in adolescent males and females who underwent gastric bypass surgery versus those who underwent adjustable gastric band surgery. Bariatric surgery can safely and substantially reduce weight and related comorbidities in morbidly obese adolescents for at least 1 year. PMID:22542199

    Observational studies have shown that bariatric surgery can lead to remission of diabetes mellitus type 2 (DMII), but randomized controlled trials have been lacking. Recently, randomized controlled trials comparing bariatric surgery with optimal medical treatment in patients suffering from poorly controlled DMII, have been performed. These trials show that bariatric surgery in general, and the malabsorptive procedures in particular, are more effective than medical treatment in achieving remission of DMII. These procedures should therefore be considered in the treatment of patients with DMII and obesity.

    There is a large body of evidence indicating that bariatric surgery provides durable weight loss and health benefits to patients who are obese and have comorbidities such as type 2 diabetes (T2D). However, there are still many questions related to mechanisms of metabolic improvement, predictors of success/failure, and long term consequences, which need to be answered. More recently, there has been a particular interest in the modulation of taste and food preferences that occurs after bariatric surgery and how this affects weight loss in different individuals. Animal models as well as human studies have shed some light on the role of taste in changing food preferences and how these changes may affect weight loss after surgery. The goal of this review is to discuss the physiological and behavioral consequences of bariatric surgery as a treatment for obesity and T2D, with particular emphasis on recent studies describing bariatric surgery-induced modifications in taste perception and food preferences.

    Obesity and associated type 2 diabetes mellitus (T2DM) are becoming a serious medical issue worldwide.Bariatric surgery has been shown to be the most effective and durable therapy for the treatment of morbid obese patients.Increasing data indicates bariatric surgery as metabolic surgery is an effective and novel therapy for not well controlled obese T2DM patients.The review of recent developments in bariatric/metabolic surgery covers 4 major fields.1) Improvement of safety:recent advances in laparoscopic/metabolic surgery has made this minimal invasive surgery more than ten times safer than a decade ago.The safety profile of laparoscopic/metabolic surgery is compatible with that of laparoscopic cholecystectomy now.2) New bariatric/metabolic surgery:laparoscopic sleeve gastrectomy (LSG) is becoming the leading bariatric surgery because of its simplicity and efficacy.Other new procedures,such as gastric plication,banded plication,single anastomosis (mini) gastric bypass and Duodeno-jejunal bypass with sleeve gastrectomy have all been accepted as treatment modalities for bariatric/metabolic surgery.3)Mechanism of bariatric/metabolic surgery:Restriction is the most important mechanism for bariatric surgery.Weight regain after bariatric surgery is usually associated with loss of restriction.Recent studies demonstrated that gut hormone,microbiota and bile acid changes after bariatric surgery may play an important role in durable weight loss as well as in T2DM remission.However,weight loss is still the cornerstone of T2DM remission after metabolic surgery.4) Patient selection:patients who may benefit most from bariatric surgery was found to be patients with insulin resistance.For Asian T2DM patients,the indication of metabolic surgery has been set to those with not well controlled (HbA1c > 7.5%) disease and with their BMI > 27.5 Kg/m2.A novel diabetes surgical score,ABCD score,is a simple system for predicting the success of surgical therapy for T2DM.

    Full Text Available OBJETIVO: Estudar a função sistólica e diastólica por meio da ecocardiografia Doppler em pacientes assintomáticos com obesidade grave. MÉTODOS: Foram avaliados, por meio de ecocardiograma transtorácico, 30 pacientes candidatos a cirurgia bariátrica, com IMC médio de 49,2±8,8 kg/m², sem história de cardiopatia prévia. RESULTADOS: Observou-se aumento de câmaras esquerdas em 42,9% da amostra, disfunção diastólica em 54,6%, hipertrofia ventricular esquerda em 82,1%, com padrão geométrico do tipo hipertrofia excêntrica em metade dos casos. A indexação da massa ventricular esquerda com a altura diagnosticou significativamente mais hipertrofia do que a indexação com a superfície corpórea (p = 0,0053, sendo esse índice mais apropriado para determinação de hipertrofia ventricular em obesos. Correlações entre hipertrofia ventricular esquerda com tempo de obesidade e níveis pressóricos foram positivas, bem como correlações entre o índice de massa corpórea e indicadores de disfunção diastólica. CONCLUSÃO: Este estudo mostrou que o ecocardiograma, realizado em portadores de obesidade grave assintomáticos, revelou alterações cardíacas estruturais comuns na miocardiopatia da obesidade, que podem associar-se ao desenvolvimento de insuficiência cardíaca, arritmias e morte súbita, possibilitando a identificação de pacientes sob maior risco cardiovascular.OBJECTIVE: To study the systolic and diastolic function of asymptomatic patients with severe obesity using a Doppler echocardiography.

    To examine neuropsychological deficits associated with the human immunodeficiency virus (HIV), 25 asymptomatic homosexual men and sexual partners of intravenous drug users and 25 seronegative homosexual men and nonhigh-risk heterosexuals were assessed on measures of fine motor control, visual scanning, attention, depression, and global psychological functioning. Analysis suggested that HIV infection is associated with reduced fine motor control. Seropositivity is associated with elevated depression and global psychological maladjustment. When depression and global adjustment were analyzed as covariates, motor slowing was evident in the seropositive group. These findings suggest an association between motor slowing and HIV infection in asymptomatic subjects and point to the necessity of measuring affect at least as a control variable. Further study is needed to determine whether the fine motor deficit evident in this sample is limited to distinct subgrouping of the over-all sample. PMID:2762096

    2013-12-01

    Follicular lymphoma is a heterogeneous disease in which some patients present an indolent evolution for decades and others, a rather aggressive form of the disease requiring immediate therapy. While immunochemotherapy has emerged as a standard of care for symptomatic patients, treatment of the asymptomatic population remains controversial. Since the disease is still considered incurable, delayed initiation of therapy is an acceptable option. However, four single injections of rituximab can result in an acceptable clinical response and can improve the duration of the interval without cytotoxic therapy. With recent therapeutic approaches that enable substantial improvements in life expectancy for follicular lymphoma patients, limiting short- or long-term treatment toxicities appears as a new concern in the asymptomatic population. Based on these options, the challenge is to preserve patient quality of life and prolong survival: from the patient's perspective, his/her opinion is therefore of significant importance.

  19. Cerebral blood flow in asymptomatic individuals

    International Nuclear Information System (INIS)

    We studied the relationship between cortical grey matter flow (CBF) and age, cerebrovascular risk factors and the severity of subcortical hypersignals (HS, hyperintensity score in MRI) in 47 asymptomatic subjects with cerebrovascular risk factors. Multiple regression analysis revealed that HS was most strongly related to CBF, and that hematocrit, age and evidence of ischemic change detected in the electrocardiogram also appeared to be independent determinants of CBF. Both the severity and location of hypersignals were correlated with CBF. The most significant negative correlation observed was that between CBF and HS in the basal ganglia-thalamic region, where the degree of signal abnormality was modest. Decreased CBF in asymptomatic subjects with cerebrovascular risk factors may be related to microcirculatory disturbance associated with elevated hematocrit and an increase in the number of risk factors, and functional suppression of cerebral cortex due to the neuronal disconnection associated with subcortical lesions. In addition, impaired cerebral circulation may be related to MRI signal abnormalities. (author)

    Full Text Available This cross-sectional study is conducted to determine the prevalence of asymptomatic cervical spine subluxation in rheumatoid arthritis patients by plain radiographs and its relation to demographic and clinical characteristics, disease activity measures and medications. 100 rheumatoid arthritis patients (18 male and 82 female were selected randomly, according to the American college of Rheumatology Criteria, who were under follow up in the rheumatology clinic. A complete history was taken, and physical examination has been done with focus on the cervical spine to determine their demographic data, disease duration, age of disease onset, drug history, swollen and tender joint counts, and ESR, Hb, CRP, RF levels. The disease activity of patients with rheumatoid arthritis was measured using the disease activity score 28. Radiographs of the cervical spine included lateral views taken in flexion, extension, neutral position of the neck and anterioposterior and odontoid projection view. Asymptomatic cervical spine subluxation was found in 17 of the 100 patients (17%. The prevalence of, anterior atlantoaxial subluxation, atlantoaxial impaction and subaxial subluxation was 10(10%, 5(5% and 6(6%, respectively. Posterior subluxation was not detected. The only characteristic that showed meaningful relationship with cervical spine subluxation was CRP (P=0.036. Our results showed that patients with RA, who have cervical spine subluxation cannot be distinguished on the basis of symptoms. Cervical spine involvement is common and may be asymptomatic, indicating routine cervical spine imaging is needed in patients with RA.

    Bariatric surgery, initially intended as a weight-loss procedure, is superior to standard lifestyle intervention and pharmacological therapy for type 2 diabetes in obese individuals. Intensive medical management of hyperglycemia is associated with improved microvascular outcomes. Whether or not the reduction in hyperglycemia observed after bariatric surgery translates to improved microvascular outcomes is yet to be determined. There is substantial heterogeneity in the data relating to the impact of bariatric surgery on diabetic retinopathy (DR), the most common microvascular complication of diabetes. This review aims to collate the recent data on retinal outcomes after bariatric surgery. This comprehensive evaluation revealed that the majority of DR cases remain stable after surgery. However, risk of progression of pre-existing DR and the development of new DR is not eliminated by surgery. Instances of regression of DR are also noted. Potential risk factors for deterioration include severity of DR at the time of surgery and the magnitude of glycated hemoglobin reduction. Concerns also exist over the detrimental effects of postprandial hypoglycemia after surgery. In vivo studies evaluating the chronology of DR development and the impact of bariatric surgery could provide clarity on the situation. For now, however, the effect of bariatric surgery on DR remains inconclusive.

  11. Bariatric surgery and nonalcoholic fatty liver disease: current and potential future treatments

    Full Text Available Nonalcoholic fatty liver disease (NAFLD and nonalcoholic steatohepatitis (NASH are increasingly common cause of chronic liver disease worldwide. The diagnosis of NASH is challenging as most affected patients are symptom-free and the role of routine screening is not clearly established. Most patients with severe obesity who undergo bariatric surgery have NAFLD, which is associated insulin resistance, type 2 diabetes mellitus (T2DM, hypertension, and obesity-related dyslipidemia. The effective treatment for NAFLD is weight reduction through lifestyle modifications, antiobesity medication, or bariatric surgery. Among these treatments, bariatric surgery is the most reliable method for achieving substantial, sustained weight loss. This procedure is safe when performed by a skilled surgeon, and the benefits include reduced weight, improved quality of life, decreased obesity-related comorbidities, and increased life expectancy. Further research is urgently needed to determine the best use of bariatric surgery with NAFLD patients at high risk of developing liver cirrhosis and its role in modulating complications of NAFLD, such as T2DM and cardiovascular disease. The current evidence suggests that bariatric surgery for patients with severe obesity decreases the grade of steatosis, hepatic inflammation, and fibrosis. However, further long-term studies are required to confirm the true effects before recommending bariatric surgery as a potential treatment for nonalcoholic steatohepatitis.

  12. The Paradigm Shift to Non-Treatment of Asymptomatic Bacteriuria

    2016-01-01

    Asymptomatic bacteriuria, also called asymptomatic urinary infection, is a common finding in healthy women, and in women and men with abnormalities of the genitourinary tract. The characterization and introduction of the quantitative urine culture in the 1950s first allowed the reliable recognition of asymptomatic bacteriuria. The observations that a substantial proportion of patients with chronic pyelonephritis at autopsy had no history of symptomatic urinary infection, and the high frequency of pyelonephritis observed in pregnant women with untreated asymptomatic bacteriuria, supported a conclusion that asymptomatic bacteriuria was harmful. Subsequent screening and long term follow-up programs for asymptomatic bacteriuria in schoolgirls and women reported an increased frequency of symptomatic urinary tract infection for subjects with asymptomatic bacteriuria, but no increased morbidity from renal failure or hypertension, or increased mortality. Treatment of asymptomatic bacteriuria did not decrease the frequency of symptomatic infection. Prospective, randomized, comparative trials enrolling premenopausal women, children, elderly populations, patients with long term catheters, and diabetic patients consistently report no benefits with antimicrobial treatment of asymptomatic bacteriuria, and some evidence of harm. Several studies have also reported that antimicrobial treatment of asymptomatic bacteriuria increases the short term risk of pyelonephritis. Current investigations are exploring the potential therapeutic intervention of establishing asymptomatic bacteriuria with an avirulent Escherichia coli strain to prevent symptomatic urinary tract infection for selected patients.

    Full Text Available A 32-year-old woman with type 2 diabetes mellitus suffering from morbid obesity with BMI 45,14 kg/m2 was operated on. Not only the type 2DM but also one of its complication known as necrobiosis lipoidica diabeticorum remitted postoperatively. Obesity should no longer be regarded simply as a cosmetic problem affecting certain individuals but an epidemic that threatens global well-being. It causes or exacerbates many health problems, and in particular, it is associated with the type 2 diabetes. Necrobiosis lipoidica is a granulomatous skin disease of unknown etiology, associated mainly with diabetes mellitus. We presented in this paper a morbid obese case of necrobiosis lipoidica diabeticorum with dramatic good response to bariatric surgery.

  14. Nutritional Optic Neuropathy Caused by Copper Deficiency After Bariatric Surgery.

    2016-06-01

    A 47-year-old woman developed severe bilateral visual loss 4 years after a Roux-en-Y gastric bypass and 24 years after vertical banded gastroplasty. Her serum copper level was 35 μg/dL (normal, 80-155 μg/dL). She was prescribed elemental copper tablets. Because her methylmalonic acid was slightly elevated, she received vitamin B12 injections as well. Five weeks later, she reported that her vision had improved and, at 10 months, her vision had recovered from 20/400 bilaterally to 20/25 in each eye. This case highlights the importance of checking copper levels in addition to the "more routine" vitamin levels, such as B1, B6, B12, E, and serum folate in patients with suspected nutritional optic neuropathy after bariatric surgery, particularly if it involved a bypass procedure.

  15. Tissue-Specific Effects of Bariatric Surgery Including Mitochondrial Function

    2011-01-01

    Full Text Available A better understanding of the molecular links between obesity and disease is potentially of great benefit for society. In this paper we discuss proposed mechanisms whereby bariatric surgery improves metabolic health, including acute effects on glucose metabolism and long-term effects on metabolic tissues (adipose tissue, skeletal muscle, and liver and mitochondrial function. More short-term randomized controlled trials should be performed that include simultaneous measurement of metabolic parameters in different tissues, such as tissue gene expression, protein profile, and lipid content. By directly comparing different surgical procedures using a wider array of metabolic parameters, one may further unravel the mechanisms of aberrant metabolic regulation in obesity and related disorders.

    A 61-year-old woman with medical history significant for morbid obesity, type II diabetes mellitus, nephrogenic diabetes insipidus and bipolar disorder, had been stable on lithium carbonate therapy for several years. She had undergone a Roux-en-Y bypass surgery and, at the time of her surgery, her lithium level was found to be 0.61 mEq/L on a maintenance dose of 600 mg orally twice per day. She was discharged 8 days postoperatively on the same lithium dose, but presented to the emergency department 12 days postoperatively with signs of lithium toxicity. Her lithium level was elevated to 1.51 mEq/L and she was treated for lithium toxicity with supportive care and, ultimately, reduction of her lithium dose. Clinicians should be aware that dramatic and poorly understood changes in drug absorption may occur after bariatric surgery. PMID:26994048

  17. Wishing for deburdening through a sustainable control after bariatric surgery

    2011-02-01

    Full Text Available The aim of this study was an in-depth investigation of the change process experienced by patients undergoing bariatric surgery. A prospective interview study was performed prior to as well as 1 and 2 years after surgery. Data analyses of the transcribed interviews were performed by means of the Grounded Theory method. A core category was identified: Wishing for deburdening through a sustainable control over eating and weight, comprising three related categories: hoping for deburdening and control through surgery, feeling deburdened and practising control through physical restriction, and feeling deburdened and trying to maintain control by own willpower. Before surgery, the participants experienced little or no control in relation to food and eating and hoped that the bariatric procedure would be the first brick in the building of a foundation that would lead to control in this area. The control thus achieved in turn affected the participants’ relationship to themselves, their roles in society, and the family as well as to health care. One year after surgery they reported established routines regarding eating as well as higher self-esteem due to weight loss. In family and society they set limits and in relation to health care staff they felt their concern and reported satisfaction with the surgery. After 2 years, fear of weight gain resurfaced and their self-image was modified to be more realistic. They were no longer totally self-confident about their condition, but realised that maintaining control was a matter of struggle to obtaining a foundation of sustainable control. Between 1 and 2 years after surgery, the physical control mechanism over eating habits started to more or less fade for all participants. An implication is that when this occurs, health care professionals need to provide interventions that help to maintain the weight loss in order to achieve a good long-term outcome.

    Background: Essential nutrients are considered for the prevention of the bone loss that occurs after bariatric surgery. Aim: Evaluate nutrients involved in bone metabolism, and relate to serum concentrations of calcium, vitamin D, and parathyroid hormone, and the use of supplements and sun exposure on the bone mass of patients who had undergone gastric bypass surgery. Methods: An observational study, with patients who had undergone the surgery 12 or more months previously, operated group (OG), compared to a control group (CG). Results: Were included 56 in OG and 27 in the CG. The mean age was 36.4±8.5 years. The individuals in the OG, compared to CG, consumed inadequate amounts of protein and daily calcium. The OG had a higher prevalence of low sun exposure, lower levels of 25OH Vitamin D (21.3±10.9 vs. 32.1±11.8 ng/dl), and increased serum levels of parathyroid hormone (68.1±32.9 vs. 39.9±11.9 pg/ml, p<0.001). Secondary hyperparathyroidism was present only in the OG (41.7%). The mean lumbar spine bone mineral density was lower in the OG. Four individuals from the OG had low bone mineral density for chronological age, and no one from the CG. Conclusion: The dietary components that affect bone mass in patients undergoing bariatric surgery were inadequate. The supplementation was insufficient and the sun exposure was low. These changes were accompanied by secondary hyperparathyroidism and a high prevalence of low bone mass in lumbar spine in these subjects. PMID:27120738

    Full Text Available Bariatric surgery as it is called now is not a new thing. First bariatric surgery was performed in 1954. Later the surgical remedy for bariatric surgery remained dormant till the popularity of laparoscopic surgery. Past decade has seen a tremendous increase in the number of bariatric or metabolic surgical procedures. This trend may continue because of the epidemic of obesity throughout globe and its rising prevalence among children. Advocates of bariatric surgery consider it the most effective and only treatment for morbid obesity and its co morbidities. To simplify; two types of procedures are performed. 1. Restrictive- where the intake of calories are prevented by restricting food intake. 2. The other one is malabsorptive- where food rich in calories is prevented to get absorbed. Operations based on these principles are-Laparoscopic adjustable gastric band and Vertical sleeve resection of stomach; for restrictive surgery and Laparoscopic biliopancreatic diversion with or without duodenal switch; for malabsorptive procedures. Both types have their own merits and demerits, many of which are almost unacceptable. To counter each other’s’ demerits certain combinations of both types are evolved like Roux-en-Y gastric bypass; it combines both restrictive and malabsorptive components. Each operation has its own merits and demerits. Important points for the patient and surgeon alike in the decision to proceed with bariatric operation include – the technical aspects of operation, post-operative complications including long term nutritional problems, Magnitude of initial and later steady weight loss over the period and correction of obesity related comorbidities. Here, the merits and demerits of present day laparoscopic bariatric surgical procedures are reviewed and related controversial aspects related to them are discussed. Right patient selection; right selection of operative procedure for an individual patient and more importantly right

    Background The prevalence of obesity, as well as use of bariatric surgery, has increased worldwide. The aim of the present study was to investigate the potential differences in the use of bariatric surgery among Swedes and immigrants in Sweden and whether the hypothesized differences remain after adjustment for socioeconomic factors. Methods A closed cohort of all individuals aged 20–64 years was followed during 2001–2010. Further analyses were performed in 2 periods separately (2001–2005 and 2006–2010). Age-standardized cumulative incidence rates (CR) of bariatric surgery were compared between Swedes and immigrants considering individual variables. Cox proportional hazards models were used in univariate and multivariate models for males and females. Results A total of 12,791 Swedes and 2060 immigrants underwent bariatric surgery. The lowest rates of bariatric surgery were found in immigrant men. The largest difference in CR between Swedes and immigrants was observed among low-income individuals (3.4 and 2.3 per 1000 individuals, respectively). Adjusted hazard ratios (HRs) were lower for all immigrants compared with Swedes in the second period. The highest HRs were observed among immigrants from Chile and Lebanon and the lowest among immigrants from Bosnia. Except for Nordic countries, immigrants from all other European countries had a lower HR compared with Swedes. Conclusions Men in general and some immigrant groups had a lower HR of bariatric surgery. Moreover, the difference between Swedes and immigrants was more pronounced in individuals with low socioeconomic status (income). It is unclear if underlying barriers to receive bariatric surgery are due to patients’ preferences/lack of knowledge or healthcare structures. Future studies are needed to examine potential causes behind these differences. PMID:25979207

    No studies have compared toileting-specific behaviors of encopretic children with those of asymptomatic children and have controlled for environmental factors such as parental attitudes, parenting styles, and bathroom facilities. This study prospectively examined the toileting habits of 86 chronically encopretic children compared with those of 27 asymptomatic siblings and 35 asymptomatic nonsiblings. Although encopretic children experienced significantly more soiling than did controls, the total number of daily bowel movements passed in the toilet (+/-SD) was comparable in the three groups (.92 +/- .76 in encopretic children compared with 1.14 +/- .43 and 1.08 +/- .47 in siblings and nonsiblings, respectively). Encopretic children experienced pain with defecation more often than did controls. During the 14-day study period, encopretic children complained of pain on 2.75 +/- 4.03 days compared with .58 +/- 1.84 days among sibling controls and 2.31 +/- 3.21 days among nonsibling controls. The mean pain score in encopretic children was .76 +/- 1.00 compared with .05 +/- .15 and .26 +/- .38 among siblings and nonsiblings, respectively. All three groups of children sat on the toilet without parental prompting the same number of times each day. In summary, children with chronic encopresis do not seem to avoid toileting, and they exhibit toileting behaviors that are very similar to those of asymptomatic siblings as well as to those of nonsibling controls.

There has been an increase in the rate of syphilis in the United States, especially in persons with HIV. We report a case of optic perineuritis in an asymptomatic male secondary to central nervous system (CNS syphilis. Case Report. A 41-year-old man was found to have bilateral disc edema on a routine exam. Brain MRI was unremarkable, and lumbar puncture revealed a normal opening pressure, with an elevated cerebrospinal fluid white cell count. Orbit MRI showed optic nerve sheath expansion and enhancement, consistent with optic perineuritis. He tested positive for syphilis based on serum RPR and FTA-ABS. Conclusion. Ophthalmologic findings, including disc edema, may be the presenting features of CNS syphilis. Even in asymptomatic persons, perineuritis should be considered early, as diagnosis and treatment are imperative given the progressive nature of the disease.

    Bariatric surgery is a viable treatment option for patients with extreme obesity and associated medical comorbidities; however, optimal surgical outcomes are not universal. Surgical societies, such as the American Society for Metabolic and Bariatric Surgery (ASMBS), recommend that patients undergo a presurgical psychological evaluation that includes reviewing patients' medical charts, conducting a comprehensive clinical interview, and employing some form of objective psychometric testing. Despite numerous societies recommending the inclusion of self-report assessments, only about 2/3 of clinics actively use psychological testing-some of which have limited empirical support to justify their use. This review aims to critically evaluate the psychometric properties of self-report measures when used in bariatric surgery settings and provide recommendations to help guide clinicians in selecting instruments to use in bariatric surgery evaluations. Recommended assessment batteries include use of a broadband instrument along with a narrowband eating measure. Suggestions for self-report measures to include in a presurgical psychological evaluation in bariatric surgery settings are also provided. (PsycINFO Database Record PMID:27537008

Nutritional deficiencies, together with supplement intake, were screened during pregnancy.The total population included 18 women in the restrictive and 31 in the malabsorptive group. Most micronutrients were depleted and declined significantly during pregnancy. The proportion of women with low vitamin A and B-1 levels increased to respectively 58 and 17% at delivery (P = 0.005 and 0.002. The proportion of women with vitamin D deficiency decreased from 14% at trimester 1 to 6% at delivery (P = 0.030. Mild anemia was found in respectively 22 and 40% of the women at trimester 1 and delivery. In the first trimester, most women took a multivitamin (57.1%. In the second and third trimester, the majority took additional supplements (69.4 and 73.5%. No associations were found between supplement intake and micronutrient deficiencies.Pregnant women with bariatric surgery show frequent low micronutrient levels.

    The objective of the study was to assess the interest, views and patient-perceived barriers to bariatric surgery among surgery-eligible patients. Surveys were completed at a weight management clinic and local hospital in Ontario, Canada. Patients were ≥18 years of age with a body mass index (BMI) >40 kg m(-2) or BMI > 35 kg m(-2) with ≥1 comorbidity. The sample included 105 participants, 73.3% female, with a mean BMI of 46.6 ± 7.1 kg m(-2) . Only 33.3% of participants were interested in surgery; 50.5% of participants were not interested and 16.2% had mixed feelings. Participants identified risks (69.5%) and side effects (57.1%) as significant surgical barriers. Interested participants were more likely to perceive themselves as obese, were unhappy with their current weight loss method and were less likely to fear surgery (P bariatric surgery, the majority of qualified patients are not interested in surgery mainly due to the perceived risk of surgery in general and satisfaction with current non-surgical weight loss efforts. The self-perception of obesity, as opposed to medical comorbidities, may be a stronger driver of the decision to have bariatric surgery. It is unclear if patients are aware of the effectiveness of bariatric surgery to help improve comorbidities or if bariatric surgery is perceived as being more cosmetic in nature.

    Full Text Available Abstract Introduction Bariatric surgery is on the increase throughout the world. Jejunoileal bypass bariatric procedures have fallen out of favor in western surgical centers due to the high rate of associated complications. They are, however, performed routinely in other centers and as a consequence of health tourism, management of complications related to these procedures may still be encountered. Case presentation We describe a rare case of small bowel obstruction in a 45-year-old British Caucasian woman, secondary to a volvulus of the jejunoileal anastomosis following bariatric bypass surgery. The pre-operative diagnosis was confirmed by radiology. We describe a successful surgical technique for this rare complication. Conclusions Bariatric surgery may be complicated by bowel obstruction. Early imaging is vital for diagnosis and effective management. The use of our surgical technique provides a simple and effective approach for the successful management of this bariatric complication.

    Human brucellosis is mainly caused by contact with Brucella-infected animals and their secretions and carcasses. Individuals who are continuously in contact with animals are considered to be at a high risk but only some show symptoms and are diagnosed as cases of brucellosis. Here, we showed that asymptomatic brucellosis infections occur among humans. Asymptomatic infections mainly result from less frequent contact with Brucella and/or contact with low-virulence Brucella. In our study, patients with asymptomatic infection had low antibody titres and different contact patterns. Awareness of asymptomatic infection is important for early diagnosis of brucellosis and prevention of chronic infection.

    Three-quarters of the estimated 390 million dengue virus (DENV) infections each year are clinically inapparent. People with inapparent dengue virus infections are generally considered dead-end hosts for transmission because they do not reach sufficiently high viremia levels to infect mosquitoes. Here, we show that, despite their lower average level of viremia, asymptomatic people can be infectious to mosquitoes. Moreover, at a given level of viremia, DENV-infected people with no detectable symptoms or before the onset of symptoms are significantly more infectious to mosquitoes than people with symptomatic infections. Because DENV viremic people without clinical symptoms may be exposed to more mosquitoes through their undisrupted daily routines than sick people and represent the bulk of DENV infections, our data indicate that they have the potential to contribute significantly more to virus transmission to mosquitoes than previously recognized.

    Full Text Available Intracranial lipomas are rarely observed, and accepted as the congenital lesion of central nervous system. Intracranial lipomas are usually based centrally and have benign character. In the brain, it is mostly localized in pericallosal region, quadrigeminal system, and suprasellar region and cerebellopontine angles. As being mostly asymptomatic, the patients occasionally constitute clinical symptoms according to localization area. These symptoms are systemic symptoms such as cephalalgia, drowsiness, crisis and ataxy. In this article, we aimed to present the intracranial lipomas phenomenon which was diagnosed to have caused ptosis and upper lateral sight problem, namely causing localized neurological symptom, situated in mesencephalon and having pressure effect, regarding a 57-year old male patient brought to the emergency service with the nausea, throwing up and cephalalgia ailments.

    A 78-year-old asymptomatic woman was referred to our clinic for a second opinion regarding indication for mitral valve surgery. An echocardiogram showed a moderate mitral stenosis with a concomitant severe regurgitation. The most striking feature, however, was a giant left atrium with a parasternal anteroposterior diameter of 79 mm and a left atrial volume index of 364 mL/m². There are various echocardiographic definitions of a giant left atrium, which are mainly based on measurements of the anteroposterior diameter of the left atrium using M-mode in the parasternal long axis view. Since the commonly accepted method for echocardiographic evaluation of left atrial size is left atrial volume index, we propose a cut-off value of 140 mL/m(2) for the definition of a "giant left atrium".

    Sarwer, David B; Steffen, Kristine J

    2015-11-01

    This article provides an overview of the literature on quality of life, body image and sexual behaviour in individuals with extreme obesity and who undergo bariatric surgery. Quality of life is a psychosocial construct that includes multiple domains, including health-related quality of life, weight-related quality of life, as well as other psychological constructs such as body image and sexual functioning. A large literature has documented the impairments in quality of life and these other domains in persons with obesity and extreme obesity in particular. These impairments are believed to play an influential role in the decision to undergo bariatric surgery. Individuals who undergo bariatric surgery typically report significant improvements in these and other areas of psychosocial functioning, often before they reach their maximum weight loss. The durability of these changes as patients maintain or regain weight, however, is largely unknown. PMID:26608946

    Full Text Available In patients with obesity and type 2 diabetes, recommendations for bariatric surgery are well established. However, no consensus exists regarding its role for the management of patients with type 1 diabetes and morbid obesity. We present the long-term follow-up of two women with type 1 diabetes, morbid obesity and associated comorbidities, who underwent malabsorptive bariatric surgery. More than four years after the procedure, both have a body mass index (BMI within the normal range and HbA1c levels below 7%. Also, they have been able to reduce their insulin requirements in more than 50%, their associated comorbidities have disappeared, and their overall quality of life has significantly improved. We compare our results with other recently published ones, emphasizing potential indications of bariatric surgery for patients with type 1 diabetes.

    We consider a scientific mystery which is of central importance in treating the most rapidly emerging national and global health threat: type 2 diabetes mellitus. The mystery involves a surprising effect of certain bariatric surgeries, and specifically Roux-en-Y gastric bypass (RYGB), a procedure which bypasses most of the stomach and upper intestine. An unanticipated result is that RYGB is usually found to contribute within only a few days to glucose homeostasis. This means the surgery can immediately cure patients even before they start losing weight. We are investigating this wondrous biochemical response with a quantitative model which includes the most important mechanisms. One of the major contributors is glucagon-like peptide 1 (GLP-1), an incretin whose concentration is found to increase by a large amount right after the RYGB surgical procedure. However, our results, in conjunction with the experimental and medical data, indicate that other substances must also contribute. If these substances can be definitively identified, it may be possible to replace the surgery with pharmaceuticals as the preferred treatment for type 2 diabetes.

    Full Text Available In 2012, an outstanding expert panel derived from IFSO-EC (International Federation for the Surgery of Obesity - European Chapter and EASO (European Association for the Study of Obesity, composed by key representatives of both Societies including past and present presidents together with EASO's OMTF (Obesity Management Task Force chair, agreed to devote the joint Medico-Surgical Workshop of both institutions to the topic of metabolic surgery as a pre-satellite of the 2013 European Congress on Obesity (ECO to be held in Liverpool given the extraordinarily advancement made specifically in this field during the past years. It was further agreed to revise and update the 2008 Interdisciplinary European Guidelines on Surgery of Severe Obesity produced in cooperation of both Societies by focusing in particular on the evidence gathered in relation to the effects on diabetes during this lustrum and the subsequent changes that have taken place in patient eligibility criteria. The expert panel composition allowed the coverage of key disciplines in the comprehensive management of obesity and obesity-associated diseases, aimed specifically at updating the clinical guidelines to reflect current knowledge, expertise and evidence-based data on metabolic and bariatric surgery.

  20. Endoscopic management of bariatric complications: Areview and update

    2015-01-01

    With over a third of Americans being considered obese,bariatric procedures have now become the mostperformed operation be general surgeons in theUnited States. The most common operations are theLaparoscopic Roux-en-Y Gastric Bypass, the LaparoscopicSleeve Gastrectomy, and the LaparoscopicAdjustable Gastric Band. With over 340000 bariatricprocedures preformed worldwide in 2011, the absolutenumber of complications related to these operationsis also increasing. Complications, although few, canbe life threatening. One of the most dreaded acutecomplication is the anastomotic/staple line leak. If leftundiagnosed or untreated they can lead to sepsis, multiorgan failure, and death. Smaller or contained leaks candevelop into fistulas. Although most patients with anacute anastomotic leak return to the operating room,there has been a trend to manage the stable patientwith an endoscopic stent. They offer an advantageby creating a barrier between enteric content and theleak, and will allow the patients to resume enteralfeeding much earlier. Fistulas are a complex andchronic complication with high morbidity and mortality.Postoperative bleeding although rare may also betreated locally with endoscopy. Stenosis is a morefrequent late complication and is best-managed withendoscopic therapy. Stents may not heal every fistula orstenosis, however they may prevent certain patients theneed for additional revisional surgery.

    ABSTRACT Background: Roux-en-Y gastric bypass (RYGB) is a standard therapy in bariatric surgery. Sleeve gastrectomy and gastric banding, although with good results in the literature, are showing higher rates of treatment failure to reduce obesity-associated morbidity and body weight. Other problems after bariatric may occur, as band erosion, gastroesophageal reflux disease and might be refractory to medication. Therefore, a laparoscopic conversion to a RYGB can be an effective alternative, as long as specific indications for revision are fulfilled. Objective: The objective of this study was to analyse own and literature data on revisional bariatric procedures to evaluate best alternatives to current practice. Methods: Institutional experience and systematic review from the literature on revisional bariatric surgery. Results: Endoscopic procedures are recently applied to ameliorate failure and complications of bariatric procedures. Therapy failure following RYGB occurs in up to 20%. Transoral outlet reduction is currently an alternative method to reduce the gastrojejunal anastomosis. The diameter and volume of sleeve gastrectomy can enlarge as well, which can be reduced by endoscopic full-thickness sutures longitudinally. Dumping syndrome and severe hypoglycemic episodes (neuroglycopenia) can be present in patients following RYGB. The hypoglycemic episodes have to be evaluated and usually can be treated conventionally. To avoid partial pancreatectomy or conversion to normal anatomy, a new laparoscopic approach with remnant gastric resection and jejunal interposition can be applied in non-responders alternatively. Hypoglycemic episodes are ameliorated while weight loss is sustained. Conclusion: Revisional and endoscopic procedures following bariatric surgery in patients with collateral symptomatic or treatment failure can be applied. Conventional non-surgical approaches should have been applied intensively before a revisional surgery will be indicated. Former complex

    2012-04-01

    Full Text Available Abstract Background Bariatric surgery is currently the most effective form of obesity management for those whose BMI is greater than 40 (or 35 with co morbidities. A minority of patients, however, either do not show the desired loss of excess weight or show weight regain by follow up. Research highlights some of the reasons for this variability, most of which centres on the absence of any psychological support with patients describing how although surgery fixes their body, psychological issues relating to dietary control, self esteem, coping and emotional eating remain neglected. The present study aims to evaluate the impact of a health psychology led bariatric rehabilitation service (BRS on patient health outcomes. The bariatric rehabilitation service will provide information, support and mentoring pre and post surgery and will address psychological issues such as dietary control, self esteem, coping and emotional eating. The package reflects the rehabilitation services now common place for patients post heart attack and stroke which have been shown to improve patient health outcomes. Methods/Design The study is a randomised control trial and patients will be allocated to receive either usual care or the bariatric rehabilitation service pre and post bariatric surgery. Follow up measures of weight loss and psychological issues will be taken at baseline (2 weeks preoperatively, 3, 6 and 12 months postoperatively. The contents of the bariatric service and the follow up measures are based on previous pilot work and have been developed further by the research team working closely with two patient support groups (BOSPA & WLSinfo. This study will take place in St Richard's Hospital in Chichester in the UK. Discussion It is predicted that a bariatric rehabilitation service will improve weight loss following surgery and will also facilitate changes in other psychological variables such as quality of life, dietary control, self esteem, coping and

    Bariatric surgery is the most effective method for promoting dramatic and durable weight loss in morbidly obese subjects. Furthermore, type 2 diabetes is resolved in over 80% of patients. The mechanisms behind the amelioration in metabolic abnormalities are largely unknown but may be due to changes...... in energy metabolism, gut peptides and food preference. The goal of this meeting was to review the latest research to better understand the mechanisms behind the 'magic' of bariatric surgery. Replication of these effects in a non-surgical manner remains one of the ultimate challenges for the treatment...

  5. The relationship between brain atrophy and asymptomatic cerebral lesions

    International Nuclear Information System (INIS)

    In order to clarify the relationship between brain atrophy and asymptomatic cerebral lesions, total of 235 subjects (130 males and 105 females), who had neither neurologic deficits nor organic lesions on cerebral computed tomography, were studied. The subjects' ages ranged from 40 to 86 years (mean 66). They were divided into two groups: 90 controls without hypertension or diabetes mellitus (Group C), and 145 patients with essential hypertension (Group H). Brain atrophy was diagnosed using the caudate head index (CHI). Asymptomatic cerebral lesions on magnetic resonance imaging were defined as asymptomatic lacunae and white matter lesions. Caudate head index was higher in Group H than it was in Group C, and CHI in both groups was significantly correlated with the number of asymptomatic lacunae and the severity of white matter lesions on magnetic resonance imaging. These results indicate that brain atrophy may progress along with asymptomatic cerebral lesions. (author)

    The number of adolescents undergoing weight loss surgery (WLS) has increased in response to the increasing prevalence of severe childhood obesity. Adolescents undergoing WLS require unique support, which may differ from adult programs. The aim of this study was to describe institutional and programmatic characteristics of centers participating in Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS), a prospective study investigating safety and efficacy of adolescent WLS. Data were obtained from the Teen-LABS database, and site survey completed by Teen-LABS investigators. The survey queried (1) institutional characteristics, (2) multidisciplinary team composition, (3) clinical program characteristics, and (4) clinical research infrastructure. All centers had extensive multidisciplinary involvement in the assessment, pre-operative education, and post-operative management of adolescents undergoing WLS. Eligibility criteria and pre-operative clinical and diagnostic evaluations were similar between programs. All programs have well-developed clinical research infrastructure, use adolescent-specific educational resources, and maintain specialty equipment, including high weight capacity diagnostic imaging equipment. The composition of clinical team and institutional resources is consistent with current clinical practice guidelines. These characteristics, coupled with dedicated research staff, have facilitated enrollment of 242 participants into Teen-LABS.

    Endophytes colonize an ecological niche similar to that of phytopathogens, which make them candidate for disease suppression. Anthracnose is a disease caused by Colletotrichum spp., a phytopathogen that can infect guarana (Paullinia cupana), an important commercial crop in the Brazilian Amazon. We investigated the diversity of endophytic bacteria inhabiting the phyllosphere of asymptomatic and symptomatic anthracnose guarana plants. The PCR-denaturation gradient gel electrophoresis (PCR-DGGE) fingerprints revealed differences in the structure of the evaluated communities. Detailed analysis of endophytic bacteria composition using culture-dependent and 16S rRNA clone libraries revealed the presence of Firmicutes, Proteobacteria, Actinobacteria, Bacteroidetes, and Acidobacteria phyla. Firmicutes comprised the majority of isolates in asymptomatic plants (2.40E(-4)). However, cloning and sequencing of 16S rRNA revealed differences at the genus level for Neisseria (1.4E(-4)), Haemophilus (2.1E(-3)) and Arsenophonus (3.6E(-5)) in asymptomatic plants, Aquicella (3.5E(-3)) in symptomatic anthracnose plants, and Pseudomonas (1.1E(-3)), which was mainly identified in asymptomatic plants. In cross-comparisons of the endophytic bacterial communities as a whole, symptomatic anthracnose plants contained higher diversity, as reflected in the Shannon-Weaver and Simpson indices estimation (P < 0.05). Similarly, comparisons using LIBSHUFF and heatmap analysis for the relative abundance of operational taxonomic units (OTUs) showed differences between endophytic bacterial communities. These data are in agreement with the NMSD and ANOSIM analysis of DGGE profiles. Our results suggest that anthracnose can restructure endophytic bacterial communities by selecting certain strains in the phyllosphere of P. cupana. The understanding of these interactions is important for the development of strategies of biocontrol for Colletotrichum. PMID:26090305

  8. Management of Asymptomatic Renal Stones in Astronauts

    2016-01-01

    Introduction: Management guidelines were created to screen and manage asymptomatic renal stones in U.S. astronauts. The risks for renal stone formation in astronauts due to bone loss and hypercalcuria are unknown. Astronauts have a stone risk which is about the same as commercial aviation pilots, which is about half that of the general population. However, proper management of this condition is still crucial to mitigate health and mission risks in the spaceflight environment. Methods: An extensive review of the literature and current aeromedical standards for the monitoring and management of renal stones was done. The NASA Flight Medicine Clinic's electronic medical record and Longitudinal Survey of Astronaut Health were also reviewed. Using this work, a screening and management algorithm was created that takes into consideration the unique operational environment of spaceflight. Results: Renal stone screening and management guidelines for astronauts were created based on accepted standards of care, with consideration to the environment of spaceflight. In the proposed algorithm, all astronauts will receive a yearly screening ultrasound for renal calcifications, or mineralized renal material (MRM). Any areas of MRM, 3 millimeters or larger, are considered a positive finding. Three millimeters approaches the detection limit of standard ultrasound, and several studies have shown that any stone that is 3 millimeters or less has an approximately 95 percent chance of spontaneous passage. For mission-assigned astronauts, any positive ultrasound study is followed by low-dose renal computed tomography (CT) scan, and flexible ureteroscopy if CT is positive. Other specific guidelines were also created. Discussion: The term "MRM" is used to account for small areas of calcification that may be outside the renal collecting system, and allows objectivity without otherwise constraining the diagnostic and treatment process for potentially very small calcifications of uncertain

  9. Asymptomatic cerebral infarction examined by magnetic resonance imaging (MRI)

    International Nuclear Information System (INIS)

    To find the real incidence and risk factors in asymptomatic cerebral infarction, a retrospective review was made on magnetic resonance (MR) images, which were obtained from 713 outpatients seen at the Geriatrics Research Institute Hospital between March and November of 1990. The criteria for asymptomatic cerebral infarction are: high signal intensity areas larger than 3 mm in diameter on T2-weighted image; no history of stroke; no neurological and psychological signs or symptoms with or without subjective symptoms. Symptomatic cerebral stroke was defined as stroke episodes associated with neurological signs and infarction lesions on CT or MR imaging. Of a total of 713 patients, 215 (30.2%) had symtomatic cerebral infarction and 384 (53.9%) had no cerebral lesions. The incidence of asymptomatic cerebral infarction increased with aging. Cerebral risk factors, i.e. hypertension, atrial fibrillation, and diabetes mellitus, were more significantly common in both symptomatic and asymptomatic groups than the normal control group. In the group of asymptomatic patients, T2-weighted images showed hyperintensity in the corona radiata in 60.9%, in the frontal lobe in 32.1%, in the semioval center in 28.8%, and in the basal ganglia in 23.7%. Periventricular hyperintensity was present in 124 of all 713 patients (17.4%). Common complaints in asymptomatic patients were headache (40.0%), dizziness (14.4%), and neck muscle contraction (9.8%). In conclusion, MR imaging may contribute to manage asymptomatic patients. (N.K.)

    2016-02-01

    Obesity causes major alterations in pulmonary mechanics. Obese patients undergoing bariatric surgery present mechanical ventilation-related challenges that may lead to perioperative complications. Databases were systematically searched for clinical trials of ventilation maneuvers for obese patients and bariatric surgery. Thirteen randomized controlled trials were selected. The quality of the studies was evaluated with the Critical Appraisal Skills Programme tool, and a matrix was developed to present the essential components of the studies. Eight strategies of ventilation maneuvers were identified. Recruitment maneuvers followed by positive end-expiratory pressure (PEEP) consistently demonstrated effectiveness in obese patients undergoing bariatric surgery. Pressure-controlled ventilation and volume-controlled ventilation did not differ significantly in their efficacy. Noninvasive positive pressure ventilation (NIPPV) during induction was effective in preventing atelectasis and increasing the duration of safe apnea. Equal ratio ventilation can be a useful ventilation strategy. Recruitment maneuvers followed by PEEP are effective ventilation strategies for obese patients undergoing bariatric surgery. During induction, NIPPV provides further benefit. Future studies are needed to examine the postoperative effects of recruitment maneuvers with PEEP as well as the efficacy and safety of equal ratio ventilation. PMID:26939387

    Background Splitting represents a defense mechanism that describes fragmentation of conscious experience that may occur in various psychopathological conditions. The purpose of this study was to examine the relationship of splitting with disturbed cognitive and affective functions related to impulsivity and intimate partnerships in a group of obese patients indicated for bariatric treatment and compare the results with other obese patients and patients with bulimia nervosa. Methods In this clinical study, we assessed 102 young women. The sample was divided into three subgroups: obese women (N=30), obese women indicated for bariatric treatment (N=48), and patients with bulimia nervosa (N=24). The patients were assessed using Splitting Index and Barratt Impulsivity Scale, and selected information about their intimate partnership was documented for all the participants. Results The main results of this study indicate significant differences in the relationship of splitting and impulsivity with difficulties in intimate partnerships. These differences discriminate obese patients indicated for bariatric treatment from other obese patients and patients with bulimia nervosa. Conclusion These findings may have significant implications for treatment of the obese patients indicated for bariatric treatment and their presurgery psychological evaluations. PMID:27703353

    Bariatric surgery can facilitate weight loss and improvement in medical comorbidities. It has a profound impact on nutrition, and patients need access to follow-up and aftercare. NICE CG189 Obesity emphasized the importance of a minimum of 2 years follow-up in the bariatric surgical service and recommended that following discharge from the surgical service, there should be annual monitoring as part of a shared care model of chronic disease management. NHS England Obesity Clinical Reference Group commissioned a multi-professional subgroup, which included patient representatives, to develop bariatric surgery follow-up guidelines. Terms of reference and scope were agreed upon. The group members took responsibility for different sections of the guidelines depending on their areas of expertise and experience. The quality of the evidence was rated and strength graded. Four different shared care models were proposed, taking into account the variation in access to bariatric surgical services and specialist teams across the country. The common features include annual review, ability for a GP to refer back to specialist centre, submission of follow-up data to the national data base to NBSR. Clinical commissioning groups need to ensure that a shared care model is implemented as patient safety and long-term follow-up are important. PMID:27166136

    Obesity is an important cause of physical and psychosocial morbidity and it places a significant burden on health system costs and resources. Worldwide an estimated 200 million people over 20 years are obese and in the U.K. the Department of Health report that 61.3% of people in the U.K. are either overweight or obese. Surgery for obesity (bariatric surgery) is being performed with increasing frequency in specialist centres both in the U.K. and Ireland and abroad due to the phenomenon of health tourism. Its role and success in treating medical conditions such as diabetes mellitus and hypertension in obese patients will likely lead to an even greater number of bariatric surgery procedures being performed. Patients with early postoperative complications may be managed in specialist centres but patients with later complications, occurring months or years after surgery, may present to local surgical units for assessment and management. This review will highlight the late complications of the 3 most commonly performed bariatric surgery procedures that the emergency general surgeon may encounter. It will also highlight the complications that require urgent intervention by the emergency general surgeon and those that can be safely referred to a bariatric surgeon for further management after initial assessment and investigations.

    The question of whether or not nonsurgical intentional or voluntary weight loss results in reduced mortality has been equivocal, with long-term mortality following weight loss being reported as increased, decreased, and not changed. In part, inconsistent results have been attributed to the uncertainty of whether the intentionality of weight loss is accurately reported in large population studies and also that achieving significant and sustained voluntary weight loss in large intervention trials is extremely difficult. Bariatric surgery has generally been free of these conflicts. Patients voluntarily undergo surgery and the resulting weight is typically significant and sustained. These elements, combined with possible non-weight loss-related mechanisms, have resulted in improved comorbidities, which likely contribute to a reduction in long-term mortality. This paper reviews the association between bariatric surgery and long-term mortality. From these studies, the general consensus is that bariatric surgical patients have: 1) significantly reduced long-term all-cause mortality when compared to severely obese non-bariatric surgical control groups; 2) greater mortality when compared to the general population, with the exception of one study; 3) reduced cardiovascular-, stroke-, and cancer-caused mortality when compared to severely obese non-operated controls; and 4) increased risk for externally caused death such as suicide.

    The number of obese young people continues to rise, with a corresponding increase in extreme obesity and paediatric-adolescent bariatric surgery. We aimed to (i) systematically review the literature on bariatric surgery in children and adolescents; (ii) meta-analyse change in body mass index (BMI) 1-year post-surgery and (iii) report complications, co-morbidity resolution and health-related quality of life (HRQoL). A systematic literature search (1955-2013) was performed to examine adjustable gastric band, sleeve gastrectomy, Roux-en-Y gastric bypass or biliopancreatic diversions operations among obese children and adolescents. Change in BMI a year after surgery was meta-analysed using a random effects model. In total, 637 patients from 23 studies were included in the meta-analysis. There were significant decreases in BMI at 1 year (average weighted mean BMI difference: -13.5 kg m(-2) ; 95% confidence interval [CI] -14.1 to -11.9). Complications were inconsistently reported. There was some evidence of co-morbidity resolution and improvements in HRQol post-surgery. Bariatric surgery leads to significant short-term weight loss in obese children and adolescents. However, the risks of complications are not well defined in the literature. Long-term, prospectively designed studies, with clear reporting of complications and co-morbidity resolution, alongside measures of HRQol, are needed to firmly establish the harms and benefits of bariatric surgery in children and adolescents.

    Background Chronic obstructive pulmonary disease (COPD) has a variable natural history and not all individuals follow the same course. This study aimed to identify the prevalence and characteristics of asymptomatic COPD patients from a population-based survey in China.Methods A multistage cluster sampling strategy was used in a population from seven different provinces/cities. All residents (over 40 years old) were interviewed with a standardized questionnaire and spirometry.Post-bronchodilator forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) of less than 70% was defined as the diagnostic criterion of COPD. All COPD patients screened were divided into symptomatic group and asymptomatic group according to the presence or absence of chronic respiratory symptoms. Socio-demographic,personal and exposure variables were collected and analyzed.Results Among the 1668 patients who were diagnosed with COPD from the 25 627 sampling subjects, 589 (35.3%)were asymptomatic. The age, sex, body mass index (BMI),rural and urban distributions, smoking habit and education levels were similar in the two groups. A total of 64.7% of the asymptomatic patients had no comorbidities. Cardiovascular diseases and lung cancer were more common among symptomatic COPD patients than asymptomatic group.Asymptomatic COPD group were less likely to present with poor ventilation in the kitchen, a family history of respiratory disease and recurrent childhood cough. Asymptomatic COPD patients had significantly higher FEV1 (73.1% vs. 61.0%), FVC (91.9% vs. 82.0%), and a higher ratio of FEV1/FVC (62.9% vs.58.7%) (all P <0.001) than symptomatic group. More asymptomatic patients were underdiagnosed (91.9% vs.54.3%, P<0.001) than symptomatic patients.Conclusions This large population-based survey confirmed a high prevalence of asymptomatic COPD patients in China. More use of spirometry screening test may be important to the early detection of COPD.

    Objective To investigate whether bariatric surgery increases the risk of fracture. Design Retrospective nested case-control study. Setting Patients who underwent bariatric surgery in the province of Quebec, Canada, between 2001 and 2014, selected using healthcare administrative databases. Participants 12 676 patients who underwent bariatric surgery, age and sex matched with 38 028 obese and 126 760 non-obese controls. Main outcome measures Incidence and sites of fracture in patients who had undergone bariatric surgery compared with obese and non-obese controls. Fracture risk was also compared before and after surgery (index date) within each group and by type of surgery from 2006 to 2014. Multivariate conditional Poisson regression models were adjusted for fracture history, number of comorbidities, sociomaterial deprivation, and area of residence. Results Before surgery, patients undergoing bariatric surgery (9169 (72.3%) women; mean age 42 (SD 11) years) were more likely to fracture (1326; 10.5%) than were obese (3065; 8.1%) or non-obese (8329; 6.6%) controls. A mean of 4.4 years after surgery, bariatric patients were more susceptible to fracture (514; 4.1%) than were obese (1013; 2.7%) and non-obese (3008; 2.4%) controls. Postoperative adjusted fracture risk was higher in the bariatric group than in the obese (relative risk 1.38, 95% confidence interval 1.23 to 1.55) and non-obese (1.44, 1.29 to 1.59) groups. Before surgery, the risk of distal lower limb fracture was higher, upper limb fracture risk was lower, and risk of clinical spine, hip, femur, or pelvic fractures was similar in the bariatric and obese groups compared with the non-obese group. After surgery, risk of distal lower limb fracture decreased (relative risk 0.66, 0.56 to 0.78), whereas risk of upper limb (1.64, 1.40 to 1.93), clinical spine (1.78, 1.08 to 2.93), pelvic, hip, or femur (2.52, 1.78 to 3.59) fractures increased. The increase in risk of fracture reached significance only for

  5. Weight loss by calorie restriction versus bariatric surgery differentially regulates the HPA axis in male rats

    Behavioral modifications for the treatment of obesity, including caloric restriction, have notoriously low long-term success rates relative to bariatric weight-loss surgery. The reasons for the difference in sustained weight loss are not clear. One possibility is that caloric restriction alone activates the stress-responsive hypothalamo-pituitary-adrenocortical (HPA) axis, undermining the long-term maintenance of weight loss, and that this is abrogated after bariatric surgery. Accordingly, we compared the HPA response to weight loss in 5 groups of male rats: (1) high-fat diet-induced obese (DIO) rats treated with Roux-en-Y gastric bypass surgery (RYGB, n=7), (2) DIO rats treated with vertical sleeve gastrectomy (VSG, n=11), (3) DIO rats given sham surgery and subsequently restricted to the food intake of the VSG/RYGB groups (Pair-fed, n=11), (4) ad libitum-fed DIO rats given sham surgery (Obese, n=11) and (5) ad libitum chow-fed rats given sham surgery (Lean, n=12). Compared to Lean controls, food-restricted rats exhibited elevated morning (nadir) non-stress plasma corticosterone concentrations and increased hypothalamic corticotropin releasing hormone and vasopressin mRNA expression, indicative of basal HPA activation. This was largely prevented when weight loss was achieved by bariatric surgery. DIO increased HPA activation by acute (novel environment) stress and this was diminished by bariatric surgery-, but not pair-feeding-, induced weight loss. These results suggest that the HPA axis is differentially affected by weight loss from caloric restriction versus bariatric surgery, and this may contribute to the differing long-term effectiveness of these two weight-loss approaches.

    The objective of the study was to assess the interest, views and patient-perceived barriers to bariatric surgery among surgery-eligible patients. Surveys were completed at a weight management clinic and local hospital in Ontario, Canada. Patients were ≥18 years of age with a body mass index (BMI) >40 kg m(-2) or BMI > 35 kg m(-2) with ≥1 comorbidity. The sample included 105 participants, 73.3% female, with a mean BMI of 46.6 ± 7.1 kg m(-2) . Only 33.3% of participants were interested in surgery; 50.5% of participants were not interested and 16.2% had mixed feelings. Participants identified risks (69.5%) and side effects (57.1%) as significant surgical barriers. Interested participants were more likely to perceive themselves as obese, were unhappy with their current weight loss method and were less likely to fear surgery (P effectiveness of bariatric surgery, the majority of qualified patients are not interested in surgery mainly due to the perceived risk of surgery in general and satisfaction with current non-surgical weight loss efforts. The self-perception of obesity, as opposed to medical comorbidities, may be a stronger driver of the decision to have bariatric surgery. It is unclear if patients are aware of the effectiveness of bariatric surgery to help improve comorbidities or if bariatric surgery is perceived as being more cosmetic in nature. PMID:26910303

    Full Text Available CONTEXT: Alcoholism may interfere with nutritional status, but reports are often troubled by uncertainties about ingested diet and organ function, as well as by ongoing abuse and associated conditions. OBJECTIVE: To identify nutritional and body compartment changes in stable alcoholics without confounding clinical and dietetic variables, a prospective observational pilot study was designed. Three well-matched populations were considered: subjects with chronic alcoholic pancreatitis, alcoholics without visceral disease, and healthy never-drinking adults (controls. METHODS: Subjects (n = 60 were asymptomatic males with adequate diet, no superimposed disease or complication, and alcohol-free for at least 6 months. After exclusions, 48 patients were compared. Variables encompassed dietary recall, bioimpedance analysis, biochemical profile and inflammatory markers. Main outcome measures were body fat, lean body mass, serum lipids, C-reactive protein, and selected minerals and vitamins. RESULTS: Both alcoholic populations suffered from reduced lean body mass (P = 0.001, with well-maintained body fat.Magnesium was depleted, and values of vitamin D and B12 correlated with alcohol abuse. LDL and total cholesterol was increased in alcoholics without pancreatitis (P = 0.04, but not in those with visceral damage. C-reactive protein and serum amyloid A correlated with duration of excessive drinking (P = 0.01. CONCLUSIONS: Undernutrition (diminished lean body mass, risk of magnesium and vitamin deficiencies contrasted with dyslipidemia and increased cardiovascular risk. This second danger was masked during chronic pancreatitis but not in alcoholics without visceral disease. Further studies should focus special requirements of this population.

    American cutaneous leishmaniasis (ACL) is a major public health problem caused by vector-borne protozoan intracellular parasites from the genus Leishmania, subgenera Viannia and Leishmania. Asymptomatic infection is the most common outcome after Leishmania inoculation. There is incomplete knowledge of the biological processes explaining the absence of signs or symptoms in most cases while other cases present a variety of clinical findings. Most studies of asymptomatic infection have been conducted in areas of endemic visceral leishmaniasis. In contrast, asymptomatic ACL infection has been neglected. This review is focused on the following: (1) epidemiological studies supporting the existence of asymptomatic ACL infection and (2) immunological studies conducted to understand the mechanisms responsible for controlling the parasite and avoiding tissue damage.

    Rotavirus is a major cause of infectious intestinal disease in young children; a substantial prevalence of asymptomatic infection has been reported across all age groups. In this study, the authors determined characteristics of asymptomatic rotavirus infection and potential risk factors for infection. Healthy persons were recruited at random from the general population of England during the Study of Infectious Intestinal Disease in England (1993-1996). Rotavirus infection was identified using reverse-transcription polymerase chain reaction. Multivariable logistic regression was used to compare exposures reported by participants with rotavirus infection with those of participants who tested negative. Multiple imputation was used to account for missing responses in the data set. The age-adjusted prevalence of asymptomatic rotavirus infection was 11%; prevalence was highest in children under age 18 years. Attendance at day care was a risk factor for asymptomatic rotavirus infection in children under age 5 years; living in a household with a baby that was still in diapers was a risk factor in older adults. The results suggest that asymptomatic rotavirus infection is transmitted through the same route as rotavirus infectious intestinal disease: person-to-person contact. More work is needed to understand the role of asymptomatic infections in transmission leading to rotavirus disease. PMID:20392863

    2011-09-01

    The use of bariatric surgery in the clinical management of type 2 diabetes has been recently endorsed in the clinical practice recommendations released by the most influential diabetologic associations. However, authoritative critic voices about the application of metabolic surgery in type 2 diabetes continue to appear in diabetologic literature. In this review, we will try therefore to understand what the reasons for this apparent dichotomy. In this paper, we revised what we believe are now clear evidences about the role of bariatric surgery in the treatment of type 2 diabetes in patients with morbid obesity: the efficacy of bariatric surgery in metabolic control, the existence of plausible weight-independent metabolic mechanisms at least in some bariatric procedure, and the importance of the early referral to surgery in patients with firm indications. However, we stressed also the lack of clear high-quality long-term data about the effects of bariatric surgery in the prevention of both macro- and micro-vascular hard endpoints in patients with type 2 diabetes. The accrual of these results will be critical to completely clarify the risk/benefit ratio of bariatric surgery in diabetes, as compared to current pharmacologic therapies. This may be particularly important in patients in which data on long-term efficacy are still not completed, such as in patients with lower BMI levels. PMID:21717182

    2013-03-01

    Full Text Available Context Bariatric surgery has proven to be the most effective method of treating severe obesity. Nevertheless, the acceptance of bariatric surgery is still questioned. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. However, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control. Method The medical records of 538 morbidly obese patients who underwent surgical treatment (Roux-en-Y gastric bypass surgery were reviewed. Ninety-three (17.2% patients were male and 445 (82.8% were female. The ages of the patients ranged from 18 to 70 years (average = 46, and their body mass indices ranged from 34.6 to 77 kg/m2. Results Early complications occurred in 9.6% and were distributed as follows: 2.6% presented bleeding, intestinal obstruction occurred in 1.1%, peritoneal infections occurred in 3.2%, and 2.2% developed abdominal wall infections that required hospitalization. Three (0.5% patients experienced pulmonary thromboembolism. The mortality rate was 0,55%. Conclusion The incidence of early complications was low. The diagnosis of these complications was mostly clinical, based on the presence of signs and symptoms. The value of the clinical signs and early treatment, specially in cases of sepsis, were essential to the favorable surgical outcome. The mortality was mainly related to thromboembolism and advanced age, over 65 years. Contexto A cirurgia bariátrica tem mostrado ser o método mais eficaz de tratamento da obesidade grave.

In the United Arab Emirates, a country where the rate of obesity is dramatically increasing bariatric surgery has gained popularity in recent years; however, published data on its outcomes in the Emirati population are lacking.Methods: We retrospectively reviewed the medical records of 95 patients who underwent bariatric surgery (ie, laparoscopic Roux-en-Y gastric bypass [RYGB] or laparoscopic sleeve gastrectomy at the Rashid Center for Diabetes and Research in Ajman, United Arab Emirates. Weight outcomes and metabolic marker data were abstracted at baseline and at 3, 6, and 12 months postoperatively.Results: Laparoscopic RYGB was the main procedure performed by our bariatric unit. All variables demonstrated postoperative improvement. An average excess weight loss of 68% was observed at 12 months. Fat mass was the body component that decreased the most, with an average reduction of 46%. Additionally, lipid profiles were significantly different (P<0.01 at 12 months, with triglyceride levels improving by 27% and low-density lipoprotein levels improving by 21%. Similarly, glycated hemoglobin (HbA1c levels decreased significantly (P<0.001 in patients with type 2 diabetes, with an average reduction of 73%.Conclusion: Our results show that a substantial short-term reduction in weight and significant improvements in metabolic markers followed bariatric surgery in severely obese Emirati patients. Our results are consistent with the outcomes of other internationally published studies. Additional studies are warranted to determine whether

    Noroviruses (NoV) are the most common cause of epidemic gastroenteritis world-wide. NoV infections are often asymptomatic, although individuals still shed large amounts of NoV in their stool. Understanding the differences between asymptomatic and symptomatic individuals would help in elucidating mechanisms of NoV pathogenesis. Our goal was to compare the serum cytokine responses and faecal viral RNA titres of asymptomatic and symptomatic NoV-infected individuals. We tested serum samples from infected subjects (n = 26; 19 symptomatic, seven asymptomatic) from two human challenge studies of GI.1 NoV for 16 cytokines. Samples from prechallenge and days 1-4 post-challenge were tested for these cytokines. Cytokine levels were compared to stool NoV RNA titres quantified previously by reverse transcription-polymerase chain reaction (RT-qPCR). While both symptomatic and asymptomatic groups had similar patterns of cytokine responses, the symptomatic group generally exhibited a greater elevation of T helper type 1 (Th1) and Th2 cytokines and IL-8 post-challenge compared to the asymptomatic group (all P viral RNA titre was associated positively with daily IL-6 concentration and negatively with daily IL-12p40 concentration (all P viral RNA titre, duration of viral shedding or cumulative shedding. Symptomatic individuals, compared to asymptomatic, have greater immune system activation, as measured by serum cytokines, but they do not have greater viral burden, as measured by titre and shedding, suggesting that symptoms may be immune-mediated in NoV infection.

    Full Text Available BACKGROUND: Although several studies suggest that genetic factors are associated with human UTI susceptibility, the role of DNA variation in regulating early in vivo urine inflammatory responses has not been fully examined. We examined whether candidate gene polymorphisms were associated with altered urine inflammatory profiles in asymptomatic women with or without bacteriuria. METHODOLOGY: We conducted a cross-sectional analysis of asymptomatic bacteriuria (ASB in 1,261 asymptomatic women ages 18-49 years originally enrolled as participants in a population-based case-control study of recurrent UTI and pyelonephritis. We genotyped polymorphisms in CXCR1, CXCR2, TLR1, TLR2, TLR4, TLR5, and TIRAP in women with and without ASB. We collected urine samples and measured levels of uropathogenic bacteria, neutrophils, and chemokines. PRINCIPAL FINDINGS: Polymorphism TLR2_G2258A, a variant associated with decreased lipopeptide-induced signaling, was associated with increased ASB risk (odds ratio 3.44, 95%CI; 1.65-7.17. Three CXCR1 polymorphisms were associated with ASB caused by gram-positive organisms. ASB was associated with urinary CXCL-8 levels, but not CXCL-5, CXCL-6, or sICAM-1 (P< or =0.0001. Urinary levels of CXCL-8 and CXCL-6, but not ICAM-1, were associated with higher neutrophil levels (P< or =0.0001. In addition, polymorphism CXCR1_G827C was associated with increased CXCL-8 levels in women with ASB (P = 0.004. CONCLUSIONS: TLR2 and CXCR1 polymorphisms were associated with ASB and a CXCR1 variant was associated with urine CXCL-8 levels. These results suggest that genetic factors are associated with early in vivo human bladder immune responses prior to the development of symptomatic UTIs.

    Type 2 diabetes is rapidly becoming a global health crisis. It is associated with multiple comorbidities and is placing an ever increasing financial burden on society. There is now a need to explore new methods of tackling this problem. A growing pool of evidence suggests that bariatric surgery has the potential to cure Type 2 diabetes in a select population and provide additional benefits for many of its associated comorbidities. Whilst there are various proposals that explain these phenomena, current research suggests the cause is mainly due to increased post surgical release of insulin promoting gut hormones. The aim of this paper is to introduce some of the complex issues surrounding the use of bariatric surgery in Type 2 diabetes and highlight the controversial aspects encompassing this topic.

    The increasing number of bariatric/metabolic operations as important alternatives for the treatment of obesity and type 2 diabetes brought several concerns about the intensive care of patients undergoing those procedures. Intensive Care Unit admission criteria are needed in order to better allocate resources and avoid unnecessary interventions. Furthermore, well-established protocols, helpful in many clinical situations, are not directly applicable to obese patients. Indeed, difficult airway management, mechanical ventilation, fluid therapy protocols, prophylaxis, and treatment of venous thromboembolic events have unique aspects that should be taken into consideration. Finally, new data related to planning nutrition therapy of the critically obese have been highlighted and deserve consideration. In this review, we provide an outline of recent studies related to those important aspects of the care of the bariatric/metabolic patients in critical conditions. PMID:27464648

    Full Text Available Objective: Cushing's syndrome (CS is extremely rare in morbidly obese patients. To date, no occurrences in obese patients with BMI above 60 kg/m2 have been reported in the literature. Case Report: This case report describes a patient who was admitted to the ward of the Clinical Division of Endocrinology and Metabolism of the Medical University of Vienna in preparation for bariatric surgery. The patient was a 49-year-old female who showed morbid obesity (BMI 61.6 kg/m2, hypertension, and substituted hypothyroidism. Preoperative work-up revealed CS due to an adrenal adenoma. Therefore, the patient underwent unilateral adrenalectomy followed by bariatric surgery 6 months later. Conclusion: Since undiagnosed CS might result in severe perioperative complications in a population already at increased risk, this case report underlines the importance of careful endocrine evaluation of morbidly obese patients. After all, even rare endocrine causes should be excluded.

    Full Text Available A cure for type 2 diabetes was once a mere dream but has now become a tangible and achievable goal with the unforeseen success of bariatric surgery in the treatment of both obesity and type 2 diabetes. Popular bariatric procedures such as Roux-en-Y gastric bypass and sleeve gastrectomy exhibit high rates of diabetes remission or marked improvement in glycemic control. However, the mechanism of diabetes remission following these procedures is still elusive and appears to be very complex and encompasses multiple anatomical and physiological changes. In this article, calorie restriction, improved β-cell function, improved insulin sensitivity, and alterations in gut physiology, bile acid metabolism, and gut microbiota are reviewed as potential mechanisms of diabetes remission after Roux-en-Y gastric bypass and sleeve gastrectomy.

    Summary Many Canadians pursue surgical treatment for severe obesity outside of their province or country — so-called “medical tourism.” We have managed many complications related to this evolving phenomenon. The costs associated with this care seem substantial but have not been previously quantified. We surveyed Alberta general surgeons and postoperative medical tourists to estimate costs of treating complications related to medical tourism in bariatric surgery and to understand patients’ motivations for pursuing medical tourism. Our analysis suggests more than $560 000 was spent treating 59 bariatric medical tourists by 25 surgeons between 2012 and 2013. Responses from medical tourists suggest that they believe their surgeries were successful despite some having postoperative complications and lacking support from medical or surgical teams. We believe that the financial cost of treating complications related to medical tourism in Alberta is substantial and impacts existing limited resources. PMID:26574702

  11. Asymptomatic severe aortic stenosis: challenges in diagnosis and management.

    2016-08-01

    Optimal management for asymptomatic severe aortic stenosis (AS) remains controversial. Considering the increase in elderly patients, improved surgical outcomes and the introduction of transcatheter aortic valve implantation, we must reconsider the optimal management of asymptomatic severe AS. In this article, previous studies regarding the natural history of asymptomatic severe AS were reviewed to obtain a clinical perspective of AS in the growing elderly patient population. The incidence of sudden death in asymptomatic severe AS varies among studies from 0.25% to 1.7% per year, with differences related to study design and patient background. Except for very severe AS, sudden death or AS-related cardiac death without preceding symptoms is uncommon if 'watchful' waiting strategy is possible. Therefore, early operation is reasonable in very severe AS, but it is not recommended for all patients with severe AS. Using exercise tests, plasma levels of natriuretic peptides and other parameters, risk stratification of asymptomatic severe AS is needed to select patients who may have greater benefit following early operation. On the other hand, 'watchful' waiting is not always possible in real world of our practice. Patient education and periodic echocardiography are essential in 'watchful' waiting, which is not simply waiting strategy without careful monitoring. Individualised discussion regarding the indication for early operation is necessary, considering age, clinical background, predicted natural history and operative risk in each patient. PMID:27091844

    Full Text Available With longer life expectancy, dementia based on the age-related Alzheimers’ disease (AD has turned into one of the most prevalent disorders of older age, representing a serious medical and socio-economic issue. There has been growing interest in early diagnosis of this disease, particularly regarding the initiation of new treatment strategies ahead of the onset of irreversible neuronal damage. It is accepted that the pathologic changes underlying AD appear in the brain years to decades before the symptomatic stages. Consequently, clinical measures of cognitive impairment, as used for definition of dementia, will not allow early diagnosis of AD-pathology in the mild or asymptomatic stages. Thus, a need for complementary sensitive biomarkers is apparent. Brain imaging markers are among the most promising candidates for this diagnostic challenge. Particularly, [18F]FDG PET as a marker of regional neuronal function has been demonstrated to represent a most sensitive and specific method for early identification of AD-pathology and thus for prediction of dementia of the Alzheimer type (DAT, even in the mild and asymptomatic stages. Currently, systematic data of comparable quality are hardly available for any other imaging procedure. The purpose of this article is to describe the typical findings of [18F]FDG PET in different stages of AD and to demonstrate its value for early and reliable diagnosis of Alzheimer's disease, particularly ahead of the stage of dementia of the Alzheimer’s type.

    For the purpose of studying the incidence, pathomorphology and etiology of asymptomatic ischemic cerebral lesions, we carried out a brain MRI study on 65 patients with diabetes mellitus accompanied with hypertension who are thought to belong to a high risk group of ischemic cerebrovascular diseases. Excluding the abnormality of tendon reflex due to diabetic neuropathy, sixty percent of the total patients had some mild neurological signs and symptoms, most of them was discrepancy in tendon reflex. The percentage of the patients in whom MRI disclosed some abnormalities was as high as 70%, they were lacunar stroke, multiple lacunar state, cortical infarct, and patchy high signal lesions visible only in the T{sub 2} weighted image. Lacunes or these patchy high signal lesions (considered to be the dilatation of the perivascular space or true lacunes) tended to be found along the border zone or the terminal zone. These results indicate that asymptomatic patients in whom MRI discloses the abnormalities should be considered as candidates for the future onset of multi-infarct. (author).

    Bariatric surgeries have emerged as highly effectivetreatments for obesity associated type-2 diabetesmellitus. Evidently, the desired therapeutic endpointssuch as rates of weight loss, lower levels of glycatedhemoglobin and remission of diabetes are achievedmore rapidly and last longer following bariatric surgery,as opposed to drug therapies alone. In light of thesefindings, it has been suspected that in addition tocausing weight loss dependent glucose intolerance,bariatric surgery induces other physiological changesthat contribute to the alleviation of diabetes. However,the putative post-surgical neuro-hormonal pathwaysthat underpin the therapeutic benefits of bariatricsurgery remain undefined. In a recent report, Ryan andcolleagues shed new light on the potential mechanismsthat determine the salutary effects of bariatric surgeryin mice. The authors demonstrated that the improvedglucose tolerance and weight loss in mice after verticalsleeve gastrectomy (VSG) surgery were likely to becaused by post-surgical changes in circulating bileacids and farnesoid-X receptor (FXR) signaling, both ofwhich were also mechanistically linked to changes inthe microbial ecology of the gut. The authors arrivedat this conclusion from a comparison of genome-wide,metabolic consequences of VSG surgery in obese wildtype (WT) and FXR knockout mice. Gene expressionin the distal small intestines of WT and FXR knockoutmice revealed that the pathways regulating bile acidcomposition, nutrient metabolism and anti-oxidantdefense were differentially altered by VSG surgeryin WT and FXR-/- mice. Based on these data Ryanet al , hypothesized that bile acid homeostasis andFXR signaling were mechanistically linked to the gutmicrobiota that played a role in modulating post-surgicalchanges in total body mass and glucose tolerance.The authors' data provide a plausible explanation forputative weight loss-independent benefits of bariatricsurgery and its relationship with metabolism of bileacids.

    The use of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) for the treatment of hypertensive obese patients is steadily increasing. Some studies have reported that the use of these drugs was associated with an increased risk of hypotensive episodes, during general anaesthesia. The number of bariatric procedures is also increasing worldwide, but there is a lack of studies investigating the hypotensive effect of renin-angiotensin system (RAS) blockers in severely obese patients during general anaesthesia for bariatric surgery. The aim of this pilot study was to evaluate hemodynamic changes induced by general anaesthesia in obese patients chronically treated with ACE-I or ARB compared to a control group not treated with antihypertensive therapy. Fourteen obese subjects (mean body mass index (BMI) 47.5 kg/m(2)) treated with ACE-I or ARB and twelve obese (mean BMI 45.7 kg/m2) controls not treated with antihypertensive therapy underwent general anaesthesia to perform laparoscopic bariatric surgery. Systolic blood pressure, diastolic blood pressure, and heart rate were monitored continuously and registered at different time points: T0 before induction, then at 2, 5, 7, 10, 15, 20, 30, 60, 90, 120, and 150 min after induction, and the last time point taken following recovery from anaesthesia. A progressive reduction of both systolic and diastolic blood pressure values was observed without significant differences between the two groups. A similar trend of heart rate values was observed. In conclusion, our pilot study suggests that RAS blockers may be continued during the perioperative period in patients undergoing bariatric surgery, without increasing the risk of hypotensive episodes.

    Full Text Available Background: Obesity has long been associated with an increased risk of cardiovascular disease (CVD. The aim of this study was to evaluate the impact of substantial weight loss induced by bariatric surgery on carotid intima media thickness (C-IMT (surrogate marker of early atherosclerosis and classic factors of cardiovascular risk (CVRFs. Methods: thirty-one obesity patients were evaluated for bariatric surgery. Twenty-seven were undergone surgery, 14 Roux-en-Y gastric bypass surgery (GBS and 13 sleeve gastrectomy. The four obese patients who did not undergo surgery, were performed the same evaluations. Measurements: Body weight, BMI, blood pressure, total cholesterol, TC levels, LDL-C, HDL-C, TG, fasting plasma glucose and insulin, HOMA IR, and US B-mode C-IMT was measured. Results: After 354 ± 92 days follow up, 27 patients that underwent bariatric surgery evidenced a mean body mass index decrease from 38 to 27 k/m² (p < 0.001, simultaneously was observed improvement in CVRFs, 10 years Framingham risk and a significant reduction of therapeutic requirements. C-IMT diminished from a mean of 0.58 ± 0.14 mm to 0.49 ± 0.09 mm (p = 0.0001. Four patients that did not undergo surgery increased C-IMT from 0.52 ± 0.12 to 0.58 ± 0.13 mm (p = 0.03 with no significant changes in CVRFs. Conclusion: Weight loss, one year after bariatric surgery, GBS and sleeve gastrectomy, decreases C-IMT; improve CVRFs and 10 years Framingham risk.

    2013-01-01

    Full Text Available Background: Hypoxaemia and high peak airway pressure (Ppeak are common anesthetic problems during laparoscopic bariatric surgery. Several publications have reported the successful improvement in arterial oxygenation using positive end expiratory pressure and alveolar recruitment maneuver, however, high peak airway pressure during laparoscopic bariatric surgery may limit the use of both techniques. This study was designed to determine whether equal I:E (inspiratory-to-expiratory ratio ventilation (1:1 improves arterial oxygenation with parallel decrease in the Ppeak values. Methods: Thirty patients with a body mass index ≥40 kg/m 2 scheduled for laparoscopic bariatric surgery were randomized, after creation of pneumoperitoneum, to receive I:E ratio either 1:1 (group 1, 15 patients or 1:2 (group 2, 15 patients. After a stabilization period of 30 min, patients were crossed over to the other studied I:E ratio. Ppeak, mean airway pressure (Pmean, dynamic compliance (Cdyn, arterial blood gases and hemodynamic data were collected at the end of each stabilization period. Results: Ventilation with I: E ratio of 1:1 significantly increased partial pressure of O 2 in the arterial blood (PaO 2 , Pmean and Cdyn with concomitant significant decrease in Ppeak compared to ventilation with I: E ratio of 1:2. There were no statistical differences between the two groups regarding the mean arterial pressure, heart rate, respiratory rate, end tidal CO 2 or partial pressure of CO 2 in the arterial blood. Conclusion: Equal ratio ventilation (1:1 is an effective technique in increase PaO 2 during laparoscopic bariatric surgery. It increases Pmean and Cdyn while decreasing Ppeak without adverse respiratory or hemodynamic effects.

    Gigliane Cosendey-Menegati

    2014-05-01

    Full Text Available Background: Bariatric surgery is considered the most effective immediate weight loss method for the morbidly obese, despite widely reported weight regain after a few years. Appetite, satiety and satiation control are essential to maintaining a long-term result post-surgery. Dietary fatty acids composition may be implicated in the satiety. As flaxseed is a food high in linolenic acid, we aimed to verify the influence of flaxseed fat on appetite and satiety of women after bariatric surgery.Material and methods: Six women who underwent bariatric surgery at least 2 years before participated in a single-blind crossover trial that compared the effect of two isocaloric meals on satiety, one containing whole golden flaxseed (high in polyunsaturated fatty acids and fiber (G1 and another withdefatted flaxseed (high in fiber (G2, with one week of washout period. This variable was estimated by visual analogue scales in both meals at baseline (T0, immediately after ingestion (T1 and 60, 120, and 180 minutes after the meal (T60, T120 and T180. Fasting anthropometric, body composition, laboratory tests (glucose and lipids and dietary variables, were evaluated while fasting.Results: The volunteers were obese and had excess central adiposity, even after two years of surgery and still showed habitual fibre intake below recommended levels. G1 had reduced hunger after 180 minutes compared to G2 (P=.046. Other parameters related to appetite and satiety did not differ between groups.Conclusions: Less hunger was observed after 180 minutes in whole golden flaxseed meal compared with the defatted flaxseed meal, indicating that the whole golden flaxseed meal, possibly, supports obesity treatment in the long-term after bariatric surgery by controlling appetite and satiety sensations.

    The use of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) for the treatment of hypertensive obese patients is steadily increasing. Some studies have reported that the use of these drugs was associated with an increased risk of hypotensive episodes, during general anaesthesia. The number of bariatric procedures is also increasing worldwide, but there is a lack of studies investigating the hypotensive effect of renin-angiotensin system (RAS) blockers in severely obese patients during general anaesthesia for bariatric surgery. The aim of this pilot study was to evaluate hemodynamic changes induced by general anaesthesia in obese patients chronically treated with ACE-I or ARB compared to a control group not treated with antihypertensive therapy. Fourteen obese subjects (mean body mass index (BMI) 47.5 kg/m(2)) treated with ACE-I or ARB and twelve obese (mean BMI 45.7 kg/m2) controls not treated with antihypertensive therapy underwent general anaesthesia to perform laparoscopic bariatric surgery. Systolic blood pressure, diastolic blood pressure, and heart rate were monitored continuously and registered at different time points: T0 before induction, then at 2, 5, 7, 10, 15, 20, 30, 60, 90, 120, and 150 min after induction, and the last time point taken following recovery from anaesthesia. A progressive reduction of both systolic and diastolic blood pressure values was observed without significant differences between the two groups. A similar trend of heart rate values was observed. In conclusion, our pilot study suggests that RAS blockers may be continued during the perioperative period in patients undergoing bariatric surgery, without increasing the risk of hypotensive episodes.

  5. From bariatric to metabolic surgery: Looking for a "diseasemodifier" surgery for type 2 diabetes

    Institute of Scientific and Technical Information of China (English)

    2016-01-01

    In this review the recent evolution of the comprehensionof clinical and metabolic consequences of bariatricsurgery is depicted. At the beginning bariatric surgeryaim was a significant and durable weight loss. Later on,it became evident that bariatric surgery was associatedwith metabolic changes, activated by unknown pathways,partially or totally independent of weight loss. Paradigmof this "metabolic" surgery is its effects on type 2diabetes mellitus (T2DM). In morbid obese subjects itwas observed a dramatic metabolic response leadingto decrease blood glucose, till diabetesremission,before the achievement of clinically significant weightloss, opening the avenue to search for putative antidiabetic"intestinal" factors. Both proximal duodenal(still unknown) and distal (GLP1) signals have beensuggested as hormonal effectors of surgery on bloodglucose decrease. Despite these findings T2DMremission was never considered a primary indicationfor bariatric surgery but only a secondary one. RecentlyT2DM remission in obese subjects with body massindex (BMI) greater than 35 has become a primaryaim for surgery. This change supports the idea that"metabolic surgery" definition could more appropriatethan bariatric, allowing to explore the possibility thatmetabolic surgery could represent a "disease modifier"for T2DM. Therefore, several patients have undergonesurgery with a primary aim of a definitive cure of T2DMand today this surgery can be proposed as an alternativetherapy. How much surgery can be considered trulymetabolic is still unknown. To be truly "metabolic" itshould be demonstrated that surgery could cause T2DMremission not only in subjects with BMI 〉 35 but alsowith BMI 〈 35 or even 〈 30. Available evidence on thistopic is discussed in this mini-review.

Therefore, the aim of this study was to analyse possible differences in salt detection thresholds and preferences for foods differing in salt content in obese persons before and after bariatric surgery with weight loss compared to non-obese individuals. Methods. Sodium chloride detection thresholds and liking for cream soups with different salt concentrations were studied with established tests. Moreover, a brief salt food questionnaire was assessed to identify the usage and awareness of salt in food. Results. The results showed similar mean sodium chloride detection thresholds between non-obese and obese participants. After bariatric surgery a non-significant increase in the salt detection threshold was observed in the obese patients (mean ± SD: 0.44 ± 0.24 g NaCl/L before OP vs. 0.64 ± 0.47 g NaCl/L after OP, p = 0.069). Cream soup liking between controls and obese patients were not significantly different. However, significant sex specific differences were detected with the tested women not liking the soups (p < 0.001). Results from the food questionnaire were similar between the groups. Conclusion. No differences between non-obese persons and obese patients were shown regarding the salt detection threshold. However, due to highly significant differences in soup liking, sex should be taken into consideration when conducting similar sensory studies. PMID:27330856

  7. Effects of Bariatric Surgery on Adipokine-Induced Inflammation and Insulin Resistance

    Full Text Available Over a third of the US population is obese and at high risk for developing type 2 diabetes, insulin resistance and other metabolic disorders. Obesity is considered a chronic low grade inflammatory condition that is primarily attributed to expansion and inflammation of adipose tissues. Indeed, adipocytes produce and secrete numerous proinflammatory and anti-inflammatory cytokines known as adipokines. When the balance of these adipokines is shifted towards higher production of proinflammatory factors, local inflammation within adipose tissues and subsequently systemic inflammation occur. These adipokines including leptin, visfatin, resistin, apelin, vaspin, and retinol binding protein-4 can regulate inflammatory responses and contribute to the pathogenesis of diabetes. These effects are mediated by key inflammatory signaling molecules including activated serine kinases such as c-Jun N-terminal kinase (JNK and serine kinases inhibitor κB kinase (IKK and insulin signaling molecules including insulin receptor substrates, protein kinase B (PKB, also known as Akt, and nuclear factor kappa B (NF-kB. Bariatric surgery can decrease body weight and improve insulin resistance in morbidly obese subjects. However, despite reports suggesting reduced inflammation and weight-independent effects of bariatric surgery on glucose metabolism, mechanisms behind such improvements are not yet well understood. This review article focuses on some of these novel adipokines and discusses their changes after bariatric surgery and their relationship to insulin resistance, fat mass, inflammation, and glucose homeostasis.

    Full Text Available Obesity and the related diabetes epidemics represent a real concern worldwide. Bariatric/metabolic surgery emerged in last years as a valuable therapeutic option for obesity and related diseases, including type 2 diabetes mellitus (T2DM. The complicated network of mechanisms involved in obesity and T2DM have not completely defined yet. There is still a debate on which would be the first metabolic defect leading to metabolic deterioration: insulin resistance or hyperinsulinemia? Insight into the metabolic effects of bariatric/metabolic surgery has revealed that, beyond weight loss and food restriction, other mechanisms can be activated by the rearrangements of the gastrointestinal tract, such as the incretinic/anti-incretinic system, changes in bile acid composition and flow, and modifications of gut microbiota; all of them possibly involved in the remission of T2DM. The complete elucidation of these mechanisms will lead to a better understanding of the pathogenesis of this disease. Our aim was to review some of the metabolic mechanisms involved in the development of T2DM in obese patients as well as in the remission of this condition in patients submitted to bariatric/metabolic surgery.

    Full Text Available Bariatric surgery, also known as metabolic surgery, is an effective treatment for morbid obesity which also offers pronounced metabolic effects including the resolution of type 2 diabetes and a decrease in cardiovascular disease and long-term cancer risk. However, the mechanisms of surgical weight loss and the long term consequences of bariatric surgery remain unclear. Bariatric surgery has been demonstrated to alter the composition of both the microbiome and the metabolic phenotype. We observed a marked shift towards Gammaproteobacteria, particularly Enterobacter hormaechei, following Roux-en-Y gastric bypass (RYGB surgery in a rat model compared with sham operated controls. Fecal water from RYGB surgery rats was highly cytotoxic to rodent cells (mouse lymphoma cell line, although In contrast, fecal water from sham operated animals showed no/very low cytotoxicity. This shift in the gross structure of the microbiome correlated with greatly increased cytotoxicity in a regulatory acceptable mouse lymphoma assay. Urinary phenylacetylglycine and indoxyl sulfate and fecal GABA, putrescine, tyramine and uracil were found to be inversely correlated with cell survival rate. This profound co-dependent response of mammalian and microbial metabolism to RYGB surgery and the impact on the cytotoxicity of the gut luminal environment suggests that RYGB exerts local and global metabolic effects which may have an influence on long term cancer risk and cytotoxic load.

    Full Text Available Objective: The aim of this investigation was to assess the effect of malabsorptive bariatric surgery (BS on the quality of life (QoL, applying the Nottingham Health Profile (NHP and the bariatric analysis and reporting outcome system (BAROS. Design: A prospective cohort study was performed in 100 adult patients (> 18 years undergoing bariatric surgery by malabsorptive technique for one year. Research methods and procedures: Patients were monitored from the beginning of the BS program until a year after the intervention, applying the NHP and the BAROS test. At baseline, the mean weight of the women was 132 ± 22 kg and the Body Mass Index (BMI was 50.7 kg/m². Results: The values obtained from different areas applying the NHP questionnaire showed statistical significant differences (p < 0.001 with respect to baseline values. According to the BAROS test, 48% of patients lost 25-49% of weight excess and 80.8% had resolved major comorbidities at 1 yr. According to the Moorehead-Ardelt QoL score, there were major improvements in employment and self-esteem in 89% and 87% of patients, respectively, and improvements in physical activity, sexual and social relationships. According to the total mean BAROS score, the outcome was considered "very good". Conclusion: NHP and BAROS questionnaires appear to be useful and easily applicable tools to assess the QoL of obese patients.

  12. Becoming a normal guy: Men making sense of long-term bodily changes following bariatric surgery

    2015-12-01

    Full Text Available Background: To date, research on bodily changes following bariatric surgery has focused predominantly on women, leaving the long-term experience of men relatively unexplored. In this paper, we draw on interviews with men who have undergone an irreversible gastric bypass procedure to explore their bodily changes more than 4 years post-surgery. We apply a phenomenological framework that draws on Leder's perspectives on the “disappearing” and “dys-appearing” body, combined with a gender-sensitive lens that draws on Connell's theory of hegemonic masculinity and Robertson's conceptions of embodied masculinity. Findings: Our principal finding was that the men negotiated their bodily changes following bariatric surgery in profoundly ambivalent ways. Although they enthusiastically praised the surgery for improving their health, self-esteem, and social functioning, they also emphasized their efforts to cope with post-surgical side effects and life-threatening complications. Our analysis elaborates on their efforts to adjust to and come to terms with these changes, focusing on episodes of hypoglycemia, severe pain and internal herniation, and the significance of physical activity and exercise. Conclusions: Our findings point to the need to acknowledge men's ways of making sense of profound and ongoing bodily changes following bariatric surgery and how these negotiations are closely intertwined with masculine ideals of embodiment and social value.

    Full Text Available Background. Dysregulated lipolysis has been implicated in mechanisms of cardiometabolic disease and inflammation in obesity. Purpose. We sought to examine the effect of bariatric weight loss on adipose tissue lipolytic gene expression and their relationship to systemic metabolic parameters in obese subjects. Methods/Results. We biopsied subcutaneous adipose tissue in 19 obese individuals (BMI 42 ± 5 kg/m2, 79% female at baseline and after a mean period of 8 ± 5 months (range 3–15 months following bariatric surgery. We performed adipose tissue mRNA expression of proteins involved in triglyceride hydrolysis and correlated their weight loss induced alterations with systemic parameters associated with cardiovascular disease risk. mRNA transcripts of adipose triglyceride lipase (ATGL, hormone-sensitive lipase (HSL, and lipid droplet proteins comparative gene identification 58 (CGI-58 and perilipin increased significantly after weight loss (p<0.05 for all. ATGL expression correlated inversely with plasma triglyceride (TG, hemoglobin A1C (HbA1C, and glucose, and HSL expression correlated negatively with glucose, while CGI-58 was inversely associated with HbA1C. Conclusion. We observed increased expression of adipose tissue lipolytic genes following bariatric weight loss which correlated inversely with systemic markers of lipid and glucose metabolism. Functional alterations in lipolysis in human adipose tissue may play a role in shaping cardiometabolic phenotypes in human obesity.

    Introduction: Project of Bariatric surgery in University clinic center (UCC) Tuzla has been initiated in 2009 as an idea of professor Dešo Mešić and soon after that Bariatric surgical team led by doctor Fuad Pasic has been created. Material and methods: Practical team education was realized in Croatia in hospital „Sisters of Mercy” under supervision of professor Miroslav-Bekavac Beslin. First bariatric operations in UCC Tuzla has been done in 2011 and it was biliopancreatic diversion (BPD) Scopinaro. Results and discussion: So far there has been done 30 operations and among them there have been used almost all operative modalities - restrictive, malabsorptive and combined (laparoscopic gastric banding-LAPGB, Roux-y mini gastric bypass, open and laparoscopic gastric sleeve resection, and over mentioned Scopinaro’s BPD). Beginning results are very promising according to the fact that almost all operated patients after one year stopped using antihypertensive, antidiabetic and antidepressant therapy, that average year’s weight loss is 35-100 kilograms and total satisfactions of patients after surgeries is obvious.

    2014-09-01

    Full Text Available INTRODUCTION: Due to the increased number of bariatric surgeries over the years, aspects contributing or hindering the achievement of outcomes, among them weight regain, have acquired increased significance. Psychological factors directly influence on this unwanted situation, but there are few studies and controversies about the degree of participation of these factors. We propose a qualitative investigation to analyze the meanings of weight regain after surgery among women and how these factors influence this outcome.METHOD: This study uses the clinical-qualitative method, by means of a semi-structured interview with open questions in an intentional sample, closed by saturation, with eight women who underwent surgery at the Bariatric Surgery Outpatient Clinic of Hospital das Clínicas, Universidade Estadual de Campinas (UNICAMP, in the state of São Paulo, Brazil.RESULTS: A feeling of defeat and failure emerges with weight regain, which contributes to social isolation; there is no regret, but gratitude for the surgery; among patients, there is a sense of feeling rejected greater than a rejection that actually exists.CONCLUSION: We found out the need for further qualitative studies that help the health team to better understand the dynamic psychological factors involved in the meaning of weight regain after bariatric surgery among women, in order to adopt appropriate conducts to deal with this problem.

  17. Can medical therapy mimic the clinical efficacy or physiological effects of bariatric surgery?

    Miras, A D; le Roux, C W

    2014-03-01

    The number of bariatric surgical procedures performed has increased dramatically. This review discusses the clinical and physiological changes, and in particular, the mechanisms behind weight loss and glycaemic improvements, observed following the gastric bypass, sleeve gastrectomy and gastric banding bariatric procedures. The review then examines how close we are to mimicking the clinical or physiological effects of surgery through less invasive and safer modern interventions that are currently available for clinical use. These include dietary interventions, orlistat, lorcaserin, phentermine/topiramate, glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase-4 inhibitors, pramlintide, dapagliflozin, the duodenal-jejunal bypass liner, gastric pacemakers and gastric balloons. We conclude that, based on the most recent trials, we cannot fully mimic the clinical or physiological effects of surgery; however, we are getting closer. A 'medical bypass' may not be as far in the future as we previously thought, as the physician's armamentarium against obesity and type 2 diabetes has recently got stronger through the use of specific dietary modifications, novel medical devices and pharmacotherapy. Novel therapeutic targets include not only appetite but also taste/food preferences, energy expenditure, gut microbiota, bile acid signalling, inflammation, preservation of β-cell function and hepatic glucose output, among others. Although there are no magic bullets, an integrated multimodal approach may yield success. Non-surgical interventions that mimic the metabolic benefits of bariatric surgery, with a reduced morbidity and mortality burden, remain tenable alternatives for patients and health-care professionals.

    Full Text Available Even though Silicone injection for breast augmentation has been related to disastrous long-term effects and complications, some patients do not develop significant symptoms at all (asymptomatic. Unfortunately, the management of asymptomatic Silicone-injected breast is still unclear and has never been reported exclusively. We present two cases of asymptomatic patients with a history of liquid Silicone injections who refused to have a mastectomy. They were concerned with the breast ptosis and chose to undergo reduction mammoplasty to improve the appearance of the breasts. Magnetic resonance imaging may be useful as an additional screening tool to confirm the diagnosis and exclude the presence of malignancy in breasts with injected Silicone. We believe that breast reduction may be the alternative option for women with a history of liquid Silicone injection who have no symptoms but desire to preserve their breasts and improve their aesthetics.

    Full Text Available Background: Psychiatric morbidity in human immunodeficiency virus (HIV patients is being studied all over the world. There is paucity of Indian literature particularly in asymptomatic HIV individuals. Aim: The aim of the following study is to establish the prevalence and the determinants of psychiatric morbidity in asymptomatic HIV patients. Materials and Methods: A cross-sectional study was undertaken to assess psychiatric morbidity as per ICD-10 dacryocystorhinostomy criteria in 100 consecutive asymptomatic seropositive HIV patients and an equal number of age, sex, education, economic and marital status matched HIV seronegative control. All subjects were assessed with the general health questionnaire (GHQ, mini mental status examination, hospital anxiety and depression scale (HADS and sensation seeking scale (SSS and the scores were analyzed statistically. Results: Asymptomatic HIV positive patients had significantly higher GHQ caseness and depression but not anxiety on HADS as compared to HIV seronegative controls. On SSS asymptomatic HIV seropositive subjects showed significant higher scores in thrill and adventure seeking, experience seeking and boredom susceptibility as compared to controls. HIV seropositive patients had significantly higher incidence of total psychiatric morbidity. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. Conclusion: Psychiatric morbidity is higher in asymptomatic HIV patients when compared to HIV seronegative controls. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. High sensation seeking and substance abuse found in HIV seropositive patients may play a vital role in engaging in high-risk behavior resulting in this dreaded illness.

    Many clinical and research findings converge to indicate that frontal lobe, basal ganglia, and related neuronal connections are primarily involved in human immunodeficiency virus (HIV) infection; frontal lobe, mainly the prefrontal cortex, has a specialized role in working memory processes. This study focused on neuropsychological evaluation of the spatial component of working memory in a sample of 34 asymptomatic HIV-infected subjects as compared with 34 age- and sex-matched seronegative control subjects. A computer-administered test assessing spatial working memory was used for the neuropsychological evaluation. The findings did not show any spatial working memory impairment during the asymptomatic phase of HIV infection.

    Parasitic diseases suppose an important health problem in people from high endemic areas, so these must be discarded properly. Usually, these infections develop asymptomatically but, in propitious situations, are likely to reactivate themselves and can cause clinical symptoms and/or complications in the receiving country. Moreover, in some cases it is possible local transmission. Early diagnosis of these parasitic diseases made by appropriate parasitological techniques and its specific treatment will benefit both, the individual and the community. These techniques must be selected according to geoepidemiological criteria, patient's origin, migration route or time spent outside the endemic area; but other factors must also be considered as its sensitivity and specificity, implementation experience and availability. Given the high prevalence of intestinal parasites on asymptomatic immigrants, it is recommended to conduct a study by coproparasitological techniques. Because of its potential severity, the screening of asymptomatic malaria with sensitive techniques such as PCR (polymerase chain reaction) is also advisable. Serological screening for Chagas disease should be performed on all Latin American immigrants, except for people from the Caribbean islands. Other important parasites, which should be excluded, are filariasis and urinary schistosomiasis, by using microscopic examination. The aim of this paper is to review the different techniques for the screening of parasitic diseases and its advices within the care protocols for asymptomatic immigrants. PMID:27474244

    Bariatric surgery is currently the most effective option for the treatment of morbid obesity and its associated comorbidities. Recent clinical and experimental findings have challenged the role of mechanical restriction and caloric malabsorption as the main mechanisms for weight loss and health benefits. Instead, other mechanisms including increased levels of satiety gut hormones, altered gut microbiota, changes in bile acid metabolism, and/or energy expenditure have been proposed as explanations for benefits of bariatric surgery. Beside the standard proximal Roux-en-Y gastric bypass and the biliopancreatic diversion with or without duodenal switch, where parts of the small intestine are excluded from contact with nutrients, resectional techniques like the sleeve gastrectomy (SG) have recently been added to the armory of bariatric surgeons. The variation of weight loss and glycemic control is vast between but also within different bariatric operations. We surveyed members of the Swiss Society for the Study of Morbid Obesity and Metabolic Disorders to assess the extent to which the phenotype of patients influences the choice of bariatric procedure. Swiss bariatric surgeons preferred Roux-en-Y gastric bypass and SG for patients with type 2 diabetes mellitus and patients with a body mass index >50 kg/m(2), which is consistent with the literature. An SG was preferred in patients with a high anesthetic risk or previous laparotomy. The surgeons' own experience was a major determinant as there is little evidence in the literature for this approach. Although trends will come and go, evidence-based medicine requires a rigorous examination of the proof to inform clinical practice. PMID:27524917

    Full Text Available Bariatric surgery is becoming a more widespread treatment for obesity. Comprehensive evidence of the long-term effects of contemporary surgery on a broad range of clinical outcomes in large populations treated in routine clinical practice is lacking. The objective of this study was to measure the association between bariatric surgery, weight, body mass index, and obesity-related co-morbidities.This was an observational retrospective cohort study using data from the United Kingdom Clinical Practice Research Datalink. All 3,882 patients registered in the database and with bariatric surgery on or before 31 December 2014 were included and matched by propensity score to 3,882 obese patients without surgery. The main outcome measures were change in weight and body mass index over 4 y; incident diagnoses of type 2 diabetes mellitus (T2DM, hypertension, angina, myocardial infarction (MI, stroke, fractures, obstructive sleep apnoea, and cancer; mortality; and resolution of hypertension and T2DM. Weight measures were available for 3,847 patients between 1 and 4 mo, 2,884 patients between 5 and 12 mo, and 2,258 patients between 13 and 48 mo post-procedure. Bariatric surgery patients exhibited rapid weight loss for the first four postoperative months, at a rate of 4.98 kg/mo (95% CI 4.88-5.08. Slower weight loss was sustained to the end of 4 y. Gastric bypass (6.56 kg/mo and sleeve gastrectomy (6.29 kg/mo were associated with greater initial weight reduction than gastric banding (2.77 kg/mo. Protective hazard ratios (HRs were detected for bariatric surgery for incident T2DM, 0.68 (95% CI 0.55-0.83; hypertension, 0.35 (95% CI 0.27-0.45; angina, 0.59 (95% CI 0.40-0.87;MI, 0.28 (95% CI 0.10-0.74; and obstructive sleep apnoea, 0.55 (95% CI 0.40-0.87.

    AIM: To study the preoperative and postoperative role of upper esophagogastroduodenoscopy (EGD) in morbidly obese patients. METHODS: This is a multicenter retrospective study by reviewing the database of patients who underwent bariatric surgery (laparoscopic sleeve gastrectomy, laparoscopic Roux en Y gastric bypass, or laparoscopic minigastric bypass) in the period between 2001 June and 2015 August (Jahra Hospital-Kuwait, Hafr Elbatin Hospital and King Saud Medical City-KSA, and Mansoura University Hospital - Egypt). Patients with age 18-65 years, body mass index (BMI) > 40, or > 35 with comorbidities after failure of many dietetic regimen and acceptable levels of surgical risk were included in the study after having an informed signed consent. We retrospectively reviewed the medical charts of all morbidly obese patients. The patients’ preoperative data included clinical history including upper digestive symptoms and preoperative full workup including EGD. Only patients whose charts revealed weather they were symptomatic or not were studied. We categorized patients accordingly into two groups; with (group A) or without (group B) upper digestive symptoms. The endoscopic findings were categorized into 4 groups based on predetermined criteria. The medical record of patients who developed stricture, leak or bleeding after bariatric surgery was reviewed. Logestic regression analysis was used to identify preoperative predictors that might be associated with abnormal endoscopic findings. RESULTS: Three thousand, two hundred and nineteen patients in the study period underwent bariatric surgery (75% LSG, 10% LRYDB, and 15% MGB). Mean BMI was 43 ± 13, mean age 37 ± 9 years, 79% were female. Twenty eight percent had presented with upper digestive symptoms (group A). EGD was considered normal in 2414 (75%) patients (9% group A vs 66% group B, P = 0.001). The abnormal endoscopic findings were found high in those patients with upper digestive symptoms.

    Background: Massive weight loss (MWL) following bariatric surgery frequently results in an excess of overstretched skin causing physical discomfort and negatively affecting quality of life, self-esteem, body image, and physical functioning. Methods: In this cross-sectional study 3 groups were compared: (1) patients prior to bariatric surgery (n = 79), (2) patients after bariatric surgery who had not undergone body contouring surgery (BCS) (n = 252), and (3) patients after bariatric surgery who underwent subsequent BCS (n = 62). All participants completed self-report questionnaires assessing body image (Multidimensional Body-Self Relations Questionnaire, MBSRQ), quality of life (IWQOL-Lite), symptoms of depression (PHQ-9), and anxiety (GAD-7). Results: Overall, 62 patients (19.2%) reported having undergone a total of 90 BCS procedures. The most common were abdominoplasties (88.7%), thigh lifts (24.2%), and breast lifts (16.1%). Post-bariatric surgery patients differed significantly in most variables from pre-bariatric surgery patients. Although there were fewer differences between patients with and without BCS, patients after BCS reported better appearance evaluation (AE), body area satisfaction (BAS), and physical functioning, even after controlling for excess weight loss and time since surgery. No differences were found for symptoms of depression and anxiety, and most other quality of life and body image domains. Discussion: Our results support the results of longitudinal studies demonstrating significant improvements in different aspects of body image, quality of life, and general psychopathology after bariatric surgery. Also, we found better AE and physical functioning in patients after BCS following bariatric surgery compared to patients with MWL after bariatric surgery who did not undergo BCS. Overall, there appears to be an effect of BCS on certain aspects of body image and quality of life but not on psychological aspects on the whole. PMID:25477839

    Full Text Available Congenital sternal defects are rare deformities frequently associated with other anomalies of the chest wall and other organ systems. Although pectus excavatum, pectus carinatum, and cleft sternum can present as isolated deformity, in most cases they are associated with heart and inner organs anomalies and described as symptoms of syndromes like Marfan syndrome, Noonan syndrome, Poland anomaly, and Cantrell pentalogy. In contrast, the etiology of an isolated defect is not well understood. We observed a short sternum (dysmorphic manubrium, hypoplastic body, and complete absence of the xiphoid process in a completely asymptomatic 13-year-old woman. A comprehensive instrumental exams panel was performed to exclude associated anomalies of the heart and of the other organ systems. The patient was completely asymptomatic and she did not need any medical or surgical treatment. To our knowledge, this is the first case of isolated short sternum reported in literature.

    The objective of this survey was to describe life insurance underwriting practices concerning children with asymptomatic hematuria and proteinuria. A questionnaire was sent to 200 companies licensed to issue life insurance policies in the state of New York. The medical director of each company was asked to respond to the insurability of children with asymptomatic hematuria and proteinuria. Two case summaries were provided with the questionnaire. Of 97 companies, 66 would offer insurance to the patient with hematuria, although 38 (58%) would charge additional premiums. In response to the problem of proteinuria, 61 companies would offer life insurance, although 50 (82%) would require higher premium charges (P life insurance, although often at higher cost. Invasive diagnostic tests are not necessary for insurers to offer insurance.

    Currently, chronic kidney disease (CKD) is a global health problem. Considering the impaired immunity of CKD patients, the relevance of infection in peritoneal dialysis (PD), and the increased prevalence of parasites in CKD patients, protozoa colonization was evaluated in PD effluent from CKD patients undergoing PD. Overnight PD effluent was obtained from 49 asymptomatic stable PD patients. Protozoa analysis was performed microscopically by searching cysts and trophozoites in direct wet mount of PD effluent and after staining smears. Protozoa were found in PD effluent of 10.2% of evaluated PD patients, namely Blastocystis hominis, in 2 patients, and Entamoeba sp., Giardia sp., and Endolimax nana in the other 3 patients, respectively. None of these patients presented clinical signs or symptoms of peritonitis at the time of protozoa screening. Our results demonstrate that PD effluent may be susceptible to asymptomatic protozoa colonization. The clinical impact of this finding should be further investigated. PMID:27659930

    Influenza infection manifests in a wide spectrum of severity, including symptomless pathogen carriers. We conducted a systematic review and meta-analysis of 55 studies to elucidate the proportional representation of these asymptomatic infected persons. We observed extensive heterogeneity among these studies. The prevalence of asymptomatic carriage (total absence of symptoms) ranged from 5.2% to 35.5% and subclinical cases (illness that did not meet the criteria for acute respiratory or influenza-like illness) from 25.4% to 61.8%. Statistical analysis showed that the heterogeneity could not be explained by the type of influenza, the laboratory tests used to detect the virus, the year of the study, or the location of the study. Projections of infection spread and strategies for disease control require that we identify the proportional representation of these insidious spreaders early on in the emergence of new influenza subtypes or strains and track how this rate evolves over time and space.

    2012-01-01

    Full Text Available Advanced carotid disease is known to be associated with symptomatic cerebrovascular diseases, such as stroke or transient ischemic attack (TIA, as well as with poststroke cognitive impairment. However, cognitive decline often occurs in patients with advanced carotid stenosis without clinically evident stroke or TIA, so it is also suspected to be an independent risk factor for dementia. Neurosonological methods enable simple and noninvasive assessment of carotid stenosis in patients at risk of advanced atherosclerosis. Cognitive status in patients diagnosed with advanced carotid stenosis is routinely not taken into consideration, although if cognitive impairment is present, such patients should probably be called symptomatic. In this paper, we discuss results of some most important studies that investigated cognitive status of patients with asymptomatic advanced carotid disease and possible mechanisms involved in the causal relationship between asymptomatic advanced carotid disease and cognitive decline.

    International Nuclear Information System (INIS)

    Objective: To select a subgroup of type-2 diabetics with two additional pre specified risk factors to see that whether there is any benefit of screening such patients. Methodology: Five hundred twenty six patients were sent for treadmill stress test or thallium scan. Those who had abnormal results were advised coronary angiography. The angiographically proven CAD was correlated with various risk factors to find the relationship between the disease and variables. Results: Two hundred thirty five (48%) patients had abnormal results and among them 158 (67%)underwent coronary angiography. Among these 21% had evidence of CAD. Coronary artery bypass grafting (CABG) was performed in 35(33%) patients, catheter based intervention (PCI) in 44(40%) patients and 30(27%) patients were not suitable for intervention. Duration of diabetes, smoking, diabetic retinopathy, albuminuria, and peripheral vascular disease were significant predictor of asymptomatic CAD. Conclusion: This study has demonstrated strong relationship between risk factors and asymptomatic CAD in type 2 diabetics. (author)

  13. Is surgery necessary for 'mild' or 'asymptomatic' hyperparathyroidism?

    Niederle, Bruno; Wémeau, Jean-Louis

    2015-09-01

    A large majority of the currently diagnosed patients with hyperparathyroidism (PHPT) are mild or asymptomatic, mainly women after menopause. Following the debate held at the 16th European Congress of Endocrinology in Wroclaw (Poland) from May 3-7, 2014, arguments are here presented by a surgeon and a medical practitioner considering these situations rather have to profit from surgery, or simply from survey. For the trained endocrine surgeon, it is evident that parathyroidectomy confirms the diagnosis and undoubtedly reduces the discomfort felt by certain patients, prevents all risks of complications, removes patients and medical teams from the monitoring and represents a real individual financial benefit. On the other hand, the medical practitioner considers that mild or asymptomatic PHPT is commonly stable, and very rare are the subjects at risk of complications, particularly of fractures; prevention of vascular and metabolic disorders, nephrolithiasis and bone rarefaction justify regular physical exercise, a safe alimentation, a sufficient calcium and high water intake, the correction of the frequent deficit in vitamin D; finally has also to be considered the impossibility to refer to specialized (endocrine) surgeons, the enormous cohort of subjects more than 50 years with 'mild' or 'asymptomatic' PHPT. The surgeon and the medical practitioner agree to consider that in patients with 'mild' or 'asymptomatic' disease, there is no place for medical treatments, in particular calcimimetics and bisphophonates. Both agree that further studies are needed to clarify the long-term prognosis of operated and non-operated PHPT in term of fractures, cardiovascular risk and mortality. Individual and collective cost/benefit ratios of surgery or survey are also still imperfectly evaluated. PMID:26101370

    Background. Clostridium difficile infection (CDI) incidence has increased dramatically over the last decade. Recent studies suggest that asymptomatic carriers may be an important reservoir of C. difficile in healthcare settings. We sought to identify the prevalence and risk factors for asymptomatic C. difficile carriage on admission to the hospital. Methods. Patients admitted to Barnes-Jewish Hospital without diarrhea were enrolled from June 2010 through October 2011. Demographic information and healthcare and medication exposures 90 days prior to admission were collected. Stool specimens or rectal swabs were collected within 48 hours of admission and stored at −30°C until cultured. Clostridium difficile isolates were typed and compared with isolates from patients with CDI. Results. A stool/swab specimen was obtained for 259 enrolled subjects on admission. Two hundred four (79%) were not colonized, 40 (15%) had toxigenic C. difficile (TCD), and 15 (6%) had nontoxigenic C. difficile. There were no differences between TCD-colonized and -uncolonized subjects for age (mean, 56 vs 58 years; P = .46), comorbidities, admission from another healthcare facility (33% vs 24%; P = .23), or recent hospitalization (50% vs 50%; P = .43). There were no differences in antimicrobial exposures in the 90 days prior to admission (55% vs 56%; P = .91). Asymptomatic carriers were colonized with strains similar to strains from patients with CDI, but the relative proportions were different. Conclusions. There was a high prevalence of TCD colonization on admission. In contrast to past studies, TCD colonization was not associated with recent antimicrobial or healthcare exposures. Additional investigation is needed to determine the role of asymptomatic TCD carriers on hospital-onset CDI incidence. PMID:24755858

    Despite great efforts in experimental and clinical research,the prognosis of pancreatic cancer (PC) has not changed significantly for decades.Detection of pre-invasive lesions or early-stage PC with small resectable cancers in asymptomatic individuals remains one of the most promising approaches to substantially improve the overall outcome of PC.Therefore,screening programs have been proposed to identify curable lesions especially in individuals with a familial or genetic predisposition for PC.In this regard,Canto et al recently contributed an important article comparing computed tomography,magnetic resonance imaging,and endoscopic ultrasound for the screening of 216 asymptomatic high-risk individuals (HRI).Pancreatic lesions were detected in 92 of 216 asymptomatic HRI (42.6%).The high diagnostic yield in this study raises several questions that need to be answered of which two will be discussed in detail in this commentary:First:which imaging test should be performed? Second and most importantly:what are we doing with incidentally detected pancreatic lesions? Which ones can be observed and which ones need to be resected?

    Huanglongbing (HLB) is a bacterial infection of citrus trees transmitted by the Asian citrus psyllid Diaphorina citri. Mitigation of HLB has focused on spraying of insecticides to reduce the psyllid population and removal of trees when they first show symptoms of the disease. These interventions have been only marginally effective, because symptoms of HLB do not appear on leaves for months to years after initial infection. Limited knowledge about disease spread during the asymptomatic phase is exemplified by the heretofore unknown length of time from initial infection of newly developing cluster of young leaves, called flush, by adult psyllids until the flush become infectious. We present experimental evidence showing that young flush become infectious within 15 d after receiving an inoculum of Candidatus Liberibacter asiaticus (bacteria). Using this critical fact, we specify a microsimulation model of asymptomatic disease spread and intensity in a grove of citrus trees. We apply a range of psyllid introduction scenarios to show that entire groves can become infected with up to 12,000 psyllids per tree in less than 1 y, before most of the trees show any symptoms. We also show that intervention strategies that reduce the psyllid population by 75% during the flushing periods can delay infection of a full grove, and thereby reduce the amount of insecticide used throughout a year. This result implies that psyllid surveillance and control, using a variety of recently available technologies, should be used from the initial detection of invasion and throughout the asymptomatic period.

    BACKGROUND: The frequency and prognostic importance of atrial fibrillation (AF) in asymptomatic mild-to-moderate aortic stenosis (AS) has not been well described. METHODS: Clinical examination, electrocardiography and echocardiography were obtained in asymptomatic patients with mild-to-moderate AS...... in 55 (3.5%) and no AF in 1,421 (90.9%). Incidence of new-onset AF was 1.2%/year; highest in those with impaired LV function. In multivariable analysis, longstanding AF was compared to no AF at baseline, associated with a 4.1-fold higher risk of heart failure (CI 1.2 to 13.8, p=0.02) and a 4.8-fold...... higher risk of non-hemorrhagic stroke (CI 1.7 to 13.6, p=0.003). CONCLUSION: Rate of AF is moderate in asymptomatic AS. Longstanding but not episodic AF was, independently predictive of increased risk of heart failure and non-hemorrhagic stroke. New-onset AF was associated with cardiac decompensation....

    Full Text Available OBJECTIVE: to determine the prevalence of radiographic signs of femoroacetabular impingement (FAI in asymptomatic adults and correlate them with data from physical examinations. METHODS: We conducted a cross-sectional study with 82 asymptomatic volunteers, 164 hips, between 40 and 60 years of age, selected by convenience. They were submitted to anamnesis and clinical examination of the hip, anteroposterior (AP pelvis radiographs with three incidences, Dunn 45° and Lequesne false profile of each hip, to measure the variables. We measured the alpha angle, anterior offset of the femoral neck, cervical diaphyseal angle, CE angle of Wiberg, acetabular index, Sharp angle, and the crossing, ischial spine and posterior wall signs. RESULTS: our sample consisted of 66% women, mean age of 50.4 years. The average alpha angle was 45.10°, SD=8.6. One quarter of the hips showed alpha angle greater than or equal to 50°; among men the prevalence was 34%, and among women, 11%. We found indicative radiographic signs of femoroacetabular impingement in 42.6% of hips, whether femoral or acetabular, and the increased alpha angle was related to the decrease in hip internal rotation (p<0.001. CONCLUSION: the radiographic findings of femoroacetabular impingement in asymptomatic patients were frequent in the studied sample. The increase in alpha angle was associated with decreased internal rotation.

    Huanglongbing (HLB) is a bacterial infection of citrus trees transmitted by the Asian citrus psyllid Diaphorina citri. Mitigation of HLB has focused on spraying of insecticides to reduce the psyllid population and removal of trees when they first show symptoms of the disease. These interventions have been only marginally effective, because symptoms of HLB do not appear on leaves for months to years after initial infection. Limited knowledge about disease spread during the asymptomatic phase is exemplified by the heretofore unknown length of time from initial infection of newly developing cluster of young leaves, called flush, by adult psyllids until the flush become infectious. We present experimental evidence showing that young flush become infectious within 15 d after receiving an inoculum of Candidatus Liberibacter asiaticus (bacteria). Using this critical fact, we specify a microsimulation model of asymptomatic disease spread and intensity in a grove of citrus trees. We apply a range of psyllid introduction scenarios to show that entire groves can become infected with up to 12,000 psyllids per tree in less than 1 y, before most of the trees show any symptoms.

    To evaluate the spectrum and frequency of MR findings of the first metatarsophalangeal joint (MTPJ) in asymptomatic volunteers. MR imaging of 30 asymptomatic forefeet was performed with a dedicated extremity 1.5-Tesla system. Participants were between 20 and 49 years of age (mean ± SD: 35.5 ± 8.4 years). Two radiologists assessed cartilage, bone, capsuloligamentous structures, and tendons of first MTPJs on MR images. Cartilage defects were observed in 27 % (n = 8) of first MTPJs, most frequently located at the base of the proximal phalanx (23 %, n = 7), whereas cartilage defects of the metatarsal head (13 %, n = 4) and the metatarsosesamoid compartment were rare (0 %-3 %, n = 0-1). Bone marrow oedema-like signal changes were present in 37 % (n = 11) and subchondral cysts in 20 % (n = 6) of first MTPJs. Hyperintense areas on intermediate-weighted sequences (range: 30-43 %, n = 9-13) and on fluid-sensitive sequences with fat suppression (range: 33-60 %, n = 10-18) within the medial and lateral collateral ligament complex were common. Plantar recesses (77 %, n = 23) and distal dorsal recesses (87 %, n = 26) were frequently observed. Cartilage defects, bone marrow oedema-like signal changes, subchondral cysts, plantar recesses, and distal dorsal recesses were common findings on MRI of first MTPJs in asymptomatic volunteers. The collateral ligaments were often heterogeneous in structure and showed increased signal intensity. (orig.)

    Full Text Available Background. Cysts in the larynx are rare and generally asymptomatic. However, large cysts in adults can be symptomatic. If they are symptomatic, they typically present with respiratory and feeding difficulties. They are usually benign in terms of pathology. Several surgical techniques may be used for treatment. Case Report. A 56-year-old man presented to our clinic with hoarseness. Routine laryngeal examination revealed a giant mass and the larynx could not be visualized. At magnetic resonance imaging (MRI, a cystic mass originating from the vallecula was detected. There was no pathology at the glottic level. We planned tracheotomy for the airway and endoscopic surgery for excision. The mass was excised using CO2 laser and was reported as benign. Conclusion. An asymptomatic vallecular cyst may cause difficult intubation in any operation. It may also cause respiratory or other complications. Airway management should be led by an ear, nose, and throat surgeon, since tracheotomy may be required. Endoscopic excision with CO2 laser is a good choice for treatment in elective cases. In this report, we discuss the diagnosis and treatment of a patient with an asymptomatic giant vallecular cyst.

    Bariatric surgery is the most effective method in the treatment of obesity and type 2 diabetes (T2DM). The aim of this study was to evaluate the effects of different types of bariatric procedures on remission of T2DM and on the fatty acid composition in subcutaneous adipose tissue. Patients included obese diabetic women who underwent bariatric surgery: biliopancreatic diversion (BPD), n=8, laparoscopic gastric banding (LAGB), n=9 or laparoscopic greater curvature plication (LGCP), n=12. Anthropometric characteristics and fatty acid composition of adipose tissue (FA AT) were analyzed before surgery, then 6 months and 2 years after surgery. FA AT was analyzed by gas chromatography. Diabetes remission was estimated. BPD was most efficient in inducing a remission of diabetes (p=0.004). Significantly higher increases in lauric (12:0), myristoleic (14:1n-5) and palmitoleic (16:1n-7) acids and delta-9 desaturase were found two years after BPD, suggesting higher lipogenesis in adipose tissue. Docosatetraenoic acid (22:4n-6) increased significantly after BPD, while docosapentaenoic acid (22:5n-3) decreased 6 months after BPD and increased after 2 years. No changes were found after LAGB and LGCP after 2 years. Bariatric surgery led to significant changes in the fatty acid composition of subcutaneous adipose tissue in severely obese diabetic women after six months and two years, and was partly influenced by the type of surgery used.

    Background Microparticles bud from cellular elements during inflammation and are associated with vascular dysfunction related to type 2 diabetes. Although weight loss is known to reduce inflammation, the metabolic effects of bariatric surgery on microparticle concentration and composition are not known. Objectives To determine the effect of bariatric surgery on microparticle concentration and correlate these changes with clinical parameters. Setting Multispecialty group practice Methods We studied 14 obese subjects with type 2 diabetes two weeks before and at one and 12 months following bariatric surgery. Nine of the patients underwent Roux-en-Y gastric bypass and 5 received gastric restrictive surgery. Results One month following surgery, body mass index was reduced by ~10%, glycemic control improved dramatically (P 60% reduction in endothelial, platelet microparticles and CRP levels (P 50% reduction in monocyte microparticles compared to pre-surgery. The reduction in monocyte microparticles one month after surgery was strongly associated with the reduction in hemoglobin A1c (P < 0.05). The reduction in monocyte microparticles 12 months following surgery correlated strongly with the reduction in body mass index (P < 0.05). Conclusion The reduction in microparticles after bariatric surgery in patients with type 2 diabetes reflects an attenuation of inflammation and this mechanism may contribute to normalization of glycemic control.

    This study examined how obese individuals acquire their motivation to undergo weight loss surgery and characterized the motivations within the framework of the self-determination theory (SDT). Participants expecting to have bariatric surgery were recruited and participated in semi-structured interviews. Interview accounts characterized different types of motivation for individuals seeking surgical weight loss treatments on the SDT continuum of relative autonomy. This study demonstrated that the more one's motivation was internally regulated, related to one's personal life and supported for competency, the more personal and hopeful were the anecdotes participants mentioned in accounts, thus the more positive the surgical outcomes were anticipated. Study limitations and future research were discussed as was the need for a systematic scheme to categorize types of motivation within the SDT, a longitudinal approach to measure actual weight loss outcomes based on the patient's pre-surgical motivation, and a further investigation with a larger sample size and balanced gender ratio. Practical implications of the study findings were also discussed as a novel strategy to internalize bariatric patients' motivation, further helping to improve their long-term quality of life post-surgery.

    Psychological difficulties for patients seeking bariatric surgery are greater and in the post-operative phase, a significant minority go on to experience significant psychosocial difficulties, increasing their risk of poorer post-operative adjustment and associated weight regain. 17 post-operative patients participated in an eight-week cognitive behavioral therapy (CBT) based psychotherapy group at the Ottawa Hospital. A pre-post design with a 3-month follow-up investigated the impact of the group on emotional eating, general as well as obesity-specific adjustment, psychological distress, and attachment. There were significant and meaningful improvements in patients' level of psychological distress, perceived difficulties in their lives, and weight-related adjustment that were maintained at a 3-month follow-up period. Although statistical change was not significant, there were also meaningful improvements in emotional overeating and relationship anxiety and avoidance. The intervention also appeared to be acceptable to patients in that attendance and satisfaction were good. Findings suggest that a short-term CBT psychotherapy group led to significant and meaningful benefits in psychological wellbeing for post-surgical bariatric patients.

Subjects: A total of 102 patients (69 women, 33 men with a mean (SD age of 42.6 (9.8 years and a mean BMI of 43.5 (4.4 kg/m2 participated. Measurements: Measurements included the NEO-PI-R (personality: neuroticism, extroversion, openness, conscientiousness and agreeableness, the TFEQ-R-21 (dysfunctional eating: emotional eating (EE, uncontrolled eating (UE and cognitive restraint of eating (CR and the HADS (anxiety and depression. Results: The personality traits neuroticism and conscientiousness were more strongly correlated with dysfunctional eating than anxiety and depression. These differences were most pronounced for emotional and cognitive restraint of eating. Emotional eating occurred more often in female than in male patients, a finding that was partially mediated by neuroticism but not by anxiety and depression. Conclusion: Personality traits may be important to address in the clinical management of morbidly obese patients seeking bariatric surgery as neuroticism is particularly salient in female patients displaying an emotional eating behaviour.

    Obesity plays relevant pathophysiological role in the development of health problems, arising as result of complex interaction of genetic, nutritional, and metabolic factors. Due to the role of adipose tissue in lipid and glucose metabolism, and low grade inflammation, it is necessary to classify obesity on the basis of body fat composition and distribution, rather than the simply increase of body weight, and the Body Mass Index. The new term of adiposopathy (''sick fat'') clearly defines the pathogenic role of adipose tissue. Four phenotypes of obese individuals have been described: (1) normal weight obese (NWO); (2) metabolically obese normal weight; (3) metabolically healthy obese; and (4) metabolically unhealthy obese or "at risk" obese. Moreover, sarcopenic obesity has been related to all the phenotypes. The category of normal weight lean, represented by metabolically healthy normal weight has been classified to distinguish from NWO. It is crucial to recommend a bariatric surgery taking into account adiposopathy and sick fat that occurs with the expansion of fat mass, changing the inflammatory and metabolic profile of the patient. Body fat percentage and genetic polymorphism have to be evaluated to personalize the best bariatric surgery intervention. PMID:26811617

    Positron emission tomography (PET) studies suggest opioidergic system dysfunction in morbid obesity, while evidence for the role of the dopaminergic system is less consistent. Whether opioid dysfunction represents a state or trait in obesity remains unresolved, but could be assessed in obese subjects undergoing weight loss. Here we measured brain μ-opioid receptor (MOR) and dopamine D2 receptor (D2R) availability in 16 morbidly obese women twice-before and 6 months after bariatric surgery-using PET with [(11)C]carfentanil and [(11)C]raclopride. Data were compared with those from 14 lean control subjects. Receptor-binding potentials (BPND) were compared between the groups and between the pre- and postoperative scans among the obese subjects. Brain MOR availability was initially lower among obese subjects, but weight loss (mean=26.1 kg, s.d.=7.6 kg) reversed this and resulted in ~23% higher MOR availability in the postoperative versus preoperative scan. Changes were observed in areas implicated in reward processing, including ventral striatum, insula, amygdala and thalamus (P'ssystem plays an important role in the pathophysiology of human obesity. Because bariatric surgery and concomitant weight loss recover downregulated MOR availability, lowered MOR availability is associated with an obese phenotype and may mediate excessive energy uptake. Our results highlight that understanding the opioidergic contribution to overeating is critical for developing new treatments for obesity. PMID:26460230

    Full Text Available Bariatric surgery is well established in reducing weight and improving the obesity-associated morbidity and mortality. Hyperammonemic encephalopathy following bariatric surgery is rare but highly fatal if not diagnosed in time and managed aggressively. Both macro- and micronutrients deficiencies play a role. A 42-year-old Hispanic female with a history of Roux-en-Y Gastric Bypass Procedure was brought to ED for progressive altered mental status. Physical exam was remarkable for drowsiness with Glasgow Coma Scale 11, ascites, and bilateral pedal edema. Labs showed elevated ammonia, low hemoglobin, low serum prealbumin, albumin, HDL, and positive toxicology. She remained obtunded despite the treatment with Narcan and flumazenil and the serum ammonia level fluctuated despite standard treatment with lactulose and rifaximin. Laboratory investigations helped to elucidate the etiology of the hyperammonemia most likely secondary to unmasking the functional deficiency of the urea cycle enzymes. Hyperammonemia in the context of normal liver function tests becomes diagnostically challenging for physicians. Severe hyperammonemia is highly fatal. Early diagnosis and aggressive treatment can alter the prognosis favorably.

    As an essential metabolic molecule, bile acids regulate triglyceride, cholesterol, energy metabolism. Bariatric surgery offers a treatment that can reduce weight and induce metabolic syndrome, but the mechanism is still unclear. New researches reveal that serum bile acids are elevated after surgery, as well as the improvement of metabolic disease. The surgery changes gastrointestinal tract, resulting in a short circuiting of the enterohepatic circulation of bile acids. Here we review the bile acids metabolism and their effect after bariatric surgery.%胆汁酸作为机体的重要代谢信号分子,参与了糖类、脂肪及能量的代谢。减重手术目前是治疗治疗肥胖症和代谢综合征有效途径之一,但其机制尚不明确。研究发现,减重手术后胆汁酸水平明显升高,并且与代谢综合征改善正相关。由于减重手术后胃肠道生理结构发生变化,必然会对胆汁酸代谢产生影响。本文对胆汁酸对代谢和对减重手术的影响作一综述。

Recent clinical and experimental findings have challenged the role of mechanical restriction and caloric malabsorption as the main mechanisms for weight loss and health benefits. Instead, other mechanisms including increased levels of satiety gut hormones, altered gut microbiota, changes in bile acid metabolism, and/or energy expenditure have been proposed as explanations for benefits of bariatric surgery. Beside the standard proximal Roux-en-Y gastric bypass and the biliopancreatic diversion with or without duodenal switch, where parts of the small intestine are excluded from contact with nutrients, resectional techniques like the sleeve gastrectomy (SG have recently been added to the armory of bariatric surgeons. The variation of weight loss and glycemic control is vast between but also within different bariatric operations. We surveyed members of the Swiss Society for the Study of Morbid Obesity and Metabolic Disorders to assess the extent to which the phenotype of patients influences the choice of bariatric procedure. Swiss bariatric surgeons preferred Roux-en-Y gastric bypass and SG for patients with type 2 diabetes mellitus and patients with a body mass index >50 kg/m2, which is consistent with the literature. An SG was preferred in patients with a high anesthetic risk or previous laparotomy. The surgeons’ own experience was a major determinant as there is little evidence in

    Behavioral modifications for the treatment of obesity, including caloric restriction, have notoriously low long-term success rates relative to bariatric weight-loss surgery. The reasons for the difference in sustained weight loss are not clear. One possibility is that caloric restriction alone activates the stress-responsive hypothalamo-pituitary-adrenocortical (HPA) axis, undermining the long-term maintenance of weight loss, and that this is abrogated after bariatric surgery. Accordingly, we compared the HPA response to weight loss in five groups of male rats: (1) high-fat diet-induced obese (DIO) rats treated with Roux-en-Y gastric bypass surgery (RYGB, n = 7), (2) DIO rats treated with vertical sleeve gastrectomy (VSG, n = 11), (3) DIO rats given sham surgery and subsequently restricted to the food intake of the VSG/RYGB groups (Pair-fed, n = 11), (4) ad libitum-fed DIO rats given sham surgery (Obese, n = 11) and (5) ad libitum chow-fed rats given sham surgery (Lean, n = 12). Compared with Lean controls, food-restricted rats exhibited elevated morning (nadir) non-stress plasma corticosterone concentration and increased hypothalamic corticotropin-releasing hormone and vasopressin mRNA expression, indicative of basal HPA activation. This was largely prevented when weight loss was achieved by bariatric surgery. DIO increased HPA activation by acute (novel environment) stress and this was diminished by bariatric surgery-, but not pair-feeding-, induced weight loss. These results indicate that the HPA axis is differentially affected by weight loss from caloric restriction versus bariatric surgery, and this may contribute to the differing long-term effectiveness of these two weight-loss approaches.

To date, most studies focused on short-term effects of bariatric surgery on the metabolic profile and found high variation in the individual responses to surgery. The aim of this study was to identify relevant metabolic changes not only shortly after bariatric surgery (Roux-en-Y gastric bypass) but also up to one year after the intervention by using untargeted metabolomics. 132 serum samples taken from 44 patients before surgery, after hospital discharge (1–3 weeks after surgery) and at a 1-year follow-up during a prospective study (NCT01271062) performed at two study centers (Austria and Switzerland). The samples included 24 patients with type 2 diabetes at baseline, thereof 9 with diabetes remission after one year. The samples were analyzed by using liquid chromatography coupled to high resolution mass spectrometry (LC-HRMS, HILIC-QExactive). Raw data was processed with XCMS and drift-corrected through quantile regression based on quality controls. 177 relevant metabolic features were selected through Random Forests and univariate testing and 36 metabolites were identified. Identified metabolites included trimethylamine-N-oxide, alanine, phenylalanine and indoxyl-sulfate which are known markers for cardiovascular risk. In addition we found a significant decrease in alanine after one year in the group of patients with diabetes remission relative to non-remission. Our analysis highlights the importance of assessing multiple points in time in subjects undergoing bariatric surgery to enable the identification of biomarkers for treatment response, cardiovascular benefit and diabetes remission. Key-findings include different trend pattern over time for various metabolites and demonstrated that short term changes should not necessarily be used to identify important long

    Full Text Available Abstract Background Severe obesity is associated with an increased risk of coronary artery disease (CAD. Bariatric surgery is an effective procedure for long term weight management as well as reduction of comorbidities. Preoperative evaluation of cardiac operative risk may often be necessary but unfortunately standard imaging techniques are often suboptimal in these subjects. The purpose of this study was to demonstrate the feasibility, safety and utility of transesophageal dobutamine stress echocardiography (TE-DSE using an adapted accelerated dobutamine infusion protocol in severely obese subjects with comorbidities being evaluated for bariatric surgery for assessing the presence of myocardial ischemia. Methods Subjects with severe obesity [body mass index (BMI >40 kg/m2] with known or suspected CAD and being evaluated for bariatric surgery were recruited. Results Twenty subjects (9M/11F, aged 50 ± 8 years (mean ± SD, weighing 141 ± 21 kg and with a BMI of 50 ± 5 kg/m2 were enrolled in the study and underwent a TE-DSE. The accelerated dobutamine infusion protocol used was well tolerated. Eighteen (90% subjects reached their target heart rate with a mean intubation time of 13 ± 4 minutes. Mean dobutamine dose was 31.5 ± 9.9 ug/kg/min while mean atropine dose was 0.5 ± 0.3 mg. TE-DSE was well tolerated by all subjects without complications including no significant arrhythmia, hypotension or reduction in blood arterial saturation. Two subjects had abnormal TE-DSE suggestive of myocardial ischemia. All patients underwent bariatric surgery with no documented cardiovascular complications. Conclusions TE-DSE using an accelerated infusion protocol is a safe and well tolerated imaging technique for the evaluation of suspected myocardial ischemia and cardiac operative risk in severely obese patients awaiting bariatric surgery. Moreover, the absence of myocardial ischemia on TE-DSE correlates well with a low operative risk of cardiac event.

    Asymptomatic conditions such as hypertension are generally hard to diagnose, absent routine medical examinations. This is especially problematic in developing countries, where most citizens do not engage in routine examinations due to limited economic resources. We study the roles of education and individual time preferences in asymptomatic disease detection and management. Using discrete choice models on a sample of 4209 hypertensive Indonesian adults surveyed between November 2007 and April 2008, we find that both education and individual time preferences play important roles. However, the effects are different for people in good health than they are for people in bad health. Education does not seem to matter for disease detection when respondents are in good general health, and its effects on disease management vary largely in magnitudes between these groups. In terms of disease detection, more educated respondents have a higher probability of being diagnosed, but only conditional on being in poor general health. Time preferences, on the other hand, matter for respondents in good general health, but the effect is not significant for those in bad health. More impatient respondents that are in good health have a higher probability of being under-diagnosed because they are more likely to forgo routine physicals. The findings point to two distinct channels through which education can affect health, and suggest that different types of policies need to be implemented, in order to reach the entire population. Traditional programs that stimulate education and improve the socio-economic status of individuals in developing countries are helpful, but they do not address the whole problem. Besides its more usual positive effects, education can also negatively affect the health of asymptomatic patients, because it reflects a higher opportunity cost of engaging in preventative health screenings.

    AIM: To investigate the presence of M2 antibodies specific for pdmary biliary cirrhosis (PBC) in asymptomatic Chinese and identify patients with early PBC.METHODS: Enzyme-linked immunosorbent assay (ElISA)tests for M2 antibodies to recombinant protein were performed in 5 011 subjects (age range, 26-85 years; mean age: 45.81±15.02 years) who took an annual physical examination. M2-positive subjects were further analyzed for immunoglobulin (Ig) classes and subclasses of M2 antibodies.Clinical, biochemical and immunological data were obtained for M2-positive subjects. In addition, ultrasonography (US)or endoscopic retrograde cholangio-pancreatography (ERCP)was performed to exclude any disorders other than PBC.RESULTS: M2 antibodies were detected in 8 (0.16%) of the 5 0LL subjects studied. Of the 8 subjects, 7 were female and 1 was male (age range: 40-74 years). An unexplained increase of serum alkaline phosphatase (ALP) and gamma glutamyl transpeptidase (γ-GT) values, often to striking levels,was detected in 4 M2-positive subjects, 3 of them accorded with the diagnostic criteria recommended by the American Association for the Study of Liver Diseases, even though they had no symptoms of PBC (such as fatigue, pruritus or jaundice).Liver biopsy was performed in two M2-positive subjects and the histology was compatible with PBC in both cases.CONCLUSION: Our data, while not assessing the true prevalence of asymptomatic PBC in the general population,suggest that asymptomatic PBC is much more common in China than has been supposed.

    Full Text Available Granuloma annulare (GA is a benign inflammatory dermatosis of unknown cause, characterized by necrobiotic dermal papules. Several morphologic forms of GA including localized, disseminated, linear, nodular, perforating, subcutaneous, pustular and arcuate dermal erythema have been reported in the literature. Disseminated GA, a rarely seen form, has been reported in association with some hematopoietic and solid malignancies; however, it has been suggested that the exact causative relationship between malignancy and GA is unclear. We present here a 66-year-old female patient with disseminated GA associated with asymptomatic multipl myeloma.

  9. Imaging in children with asymptomatic hypercalciuria and hematuria

    International Nuclear Information System (INIS)

    Fourteen children presenting with asymptomatic hematuria and hypercalciuria were evaluated with abdominal radiography, renal US, and CT of the kidneys. US and radiographic findings were negative in all patients, while CT demonstrated diffuse calcification in the medullary pyramids in eight of 14 patients (57%). Discrete foci of calcification in or adjacent to the medullary pyramids were identified in four of the eight patients (50%); one later developed overt nephrolithiasis. CT establishes that patients with hypercalciuria and hematuria are at risk for nephrocalcinosis and nephrolithiasis, suggesting that small calcifications may be important in the pathogenesis of hematuria in such patients

    Pancreatic infiltration of leukemic cells is a very rare manifestation at the onset of acute lymphoblastic leukemia (ALL) in childhood. Pancreatic enlargement in this situation is unusual and pancreatic involvement is often associated with biliary obstruction, cholestasis and pancreatitis. We report a 3-month-old girl who presented with asymptomatic leukemic infiltration of the pancreas, demonstrated by US with heterogeneous pancreatic enlargement associated with multiple hypoechogenic lesions, without cholestasis. Although these manifestations are rare, ALL should be considered a cause of pancreatic enlargement.

    Full Text Available Bezoars are intraluminal masses in the gastrointestinal tract that develop by collection of undigested materials. Though bezoars are usually located in the stomach, they also develop in the small intestines and cause mechanical intestinal obstructions there. Patients with bezoars usually present with intestinal obstruction. According to present literature data patients are asymptomatic and there is no bezoar case reported that was incidentally discovered. The bezoar of the present case was diagnosed with sonography and computed tomography, after a non-homogenous radioopacity was discovered in the right lower quadrant by an IVP investigation that was done due to recurrent urinary tract infection.

    AIM To investigate the techniques and efficacy ofperoral endoscopic reduction of dilated gastrojejunalanastomosis after bariatric surgery.METHODS: An extensive English language literaturesearch was conducted using PubMed, MEDLINE,Medscape and Google to identify peer-reviewed originaland review articles using the keywords "bariatricendoscopic suturing", "overstitch bariatric surgery","endoscopic anastomotic reduction", "bariatric surgery","gastric bypass", "obesity", "weight loss". We identifiedarticles describing technical feasibility, safety, efficacy,and adverse outcomes of overstitch endoscopic suturingsystem for transoral outlet reduction in patients withweight regain following Roux-en-Y gastric bypass (RYGB).All studies that contained material applicable to the topicwere considered. Retrieved peer-reviewed original andreview articles were reviewed by the authors and thedata extracted using a standardized collection tool. Datawere analyzed using statistical analysis as percentages ofthe event.RESULTS: Four original published articles which met oursearch criteria were pooled. The total number cases werefifty-nine with a mean age of 46.75 years (34-63 years).Eight of the patients included in those studies weremales (13.6%) and fifty-one were females (86.4%). Themean time elapsed since the primary bypass surgerywas 5.75 years. The average pre-endoscopic procedurebody mass index (BMI) was 38.68 (27.5-48.5). Meanbody weight regained post-RYGB surgery was 13.4 kgfrom their post-RYGB nadir. The average pouch length atthe initial upper endoscopy was 5.75 cm (2-14 cm). Thepre-intervention anastomotic diameter was averagedat 24.85 mm (8-40 mm). Average procedure time was74 min (50-164 min). Mean post endoscopic interventionanastomotic diameter was 8 mm (3-15 mm).

    Full Text Available The prevalence of severe obesity, defined as body mass index (BMI ≥ 35.0 kg/m(2, is rising rapidly. Given the disproportionately high health burden and healthcare costs associated with this condition, understanding the underlying aetiology, including predisposing genetic factors, is a biomedical research priority. Previous studies have suggested that severe obesity represents an extreme tail of the population BMI variation, reflecting shared genetic factors operating across the spectrum. Here, we sought to determine whether a panel of 32 known common obesity-susceptibility variants contribute to severe obesity in patients (n = 1,003, mean BMI 48.4 ± 8.1 kg/m(2 attending bariatric surgery clinics in two European centres. We examined the effects of these 32 common variants on obesity risk and BMI, both as individual markers and in combination as a genetic risk score, in a comparison with normal-weight controls (n = 1,809, BMI 18.0-24.9 kg/m(2; an approach which, to our knowledge, has not been previously undertaken in the setting of a bariatric clinic. We found strong associations with severe obesity for SNP rs9939609 within the FTO gene (P = 9.3 × 10(-8 and SNP rs2815752 near the NEGR1 gene (P = 3.6 × 10(-4, and directionally consistent nominal associations (P<0.05 for 12 other SNPs. The genetic risk score associated with severe obesity (P = 8.3 × 10(-11 but, within the bariatric cohort, this score did not associate with BMI itself (P = 0.264. Our results show significant effects of individual BMI-associated common variants within a relatively small sample size of bariatric patients. Furthermore, the burden of such low-penetrant risk alleles contributes to severe obesity in this population. Our findings support that severe obesity observed in bariatric patients represents an extreme tail of the population BMI variation. Moreover, future genetic studies focused on bariatric patients may provide valuable insights into the pathogenesis of

    Dengue has become a global problem in past few decades, with half of the world's population at risk of infection. For some countries of Asia and Latin America, severe dengue is a major cause of serious illness and even death in children. Pakistan has been reported as a hyperendemic area for dengue infection. Our study aimed to find seroprevalence of past dengue infection in asymptomatic children of Lahore with no previous history of dengue infection. A total of 400 samples were collected from children aged 1-12 years in Lahore using random sampling. The inclusion criteria were children aged 1-12 years, who had no previous symptoms of dengue fever during their lives. Children with known immunodeficiency status or fever at the time of recruitment were excluded from the study. Commercially available ELISA kits were used to determine the IgG status in sera of children. The data obtained was entered and analysed using SPSS v. 20.0. The overall prevalence of asymptomatic dengue infection was found to be 25%. There was no statistically significant difference between prevalence of infection in male and female children. There was, however, a strong relationship between increasing age of the child and number of cases with infection, with low incidence in children aged ⩽5 years. PMID:27019361

  16. Asymptomatic cerebral lesions and risk factors in normal individuals

    International Nuclear Information System (INIS)

    We studied the relationship between asymptomatic ischemic lesions on magnetic resonance imaging (MRI) and risk factors for stroke in 460 asymptomatic subjects. Focal lesions were classified into two groups according to their size. Periventricular hyperintensity (PVH) was graded from 0 to 3. We also evaluated equivocal deep white matter hyperintensity as a confluent lesion that was separate from PVH. The incidence of focal lesions below 2 mm in diameter (we regard them as etatcrible) was 5.7%, and that of lesions over 2 mm was 16.1%. Grade 2 PVH was observed in 12.6% and grade 3 PVH in 2.2%. The prevalence rate of confluent lesions was 8.7%. The age of the group which had white matter lesions was significantly higher than that of the group without lesions. Hypertension was the greatest risk factor for the occurrence of focal lesions, PVH, and confluent lesions. Diabetes mellitus was a significant risk factor only for focal lesions. Other risk factors did not display any relations to white matter abnormalities. (author)

    Dental instrumentation has long provided insight into the mechanism of musculo-skeletal function of the gnathic system. While large population studies associate dental arch displacement (DAD), especially laterally, with symptoms, mandibular condyle displacement (CD) resulting from DAD has not been targeted as possibly etiologic in the production of common muscle contraction headache (CMCH) and temporo-mandibular dysfunction (TMD). The objective was to evaluate the three-dimensional nature of DAD and CD between the seated condylar position (SCP) and the intercuspal position (ICP) and to compare results derived from large deprogrammed asymptomatic and symptomatic populations. A total of 1 192 sets of dental casts collected from asymptomatic and symptomatic populations were articulated in the SCP. The initial occlusal contact, DAD, and condylar displacement were evaluated for frequency, direction, and magnitude of displacement between the SCP and ICP. The data revealed significant displacement between the SCP and ICP of the condyles (displaced most frequently inferior (down) and posterior (distal)) and substantially increased frequency and magnitude of displacement of the dental arches (with posterior premature occlusal contacts, increased overjet, decreased overbite, midline differences, and occlusal classification changes) in symptomatic subjects. These discrepancies were statistically significant and clinically significant. The data support the concept of increased DAD and CD with dysfunction. Transverse condylar displacement, commonly presenting with dental cross bite, may be associated with CMCH and TMD. Displacement of the mandibular condyle may be an etiologic factor in CMCH and dysfunction of the temporo-mandibular joint. PMID:27357324

    Full Text Available Brugada syndrome is a rare heritable arrhythmogenic disease characterized by a coved ST segment elevation in the right precordial leads and by an increased risk of sudden cardiac arrest as a result of polymorphic ventricular tachyarrhythmias or ventricular fibrillation (1. Although implantable cardioverter defibrillators are considered to be the main therapy in patients with a history of ventricular arrhythmias or syncope, risk stratification in cases without these symptoms remains controversial. Patients with confirmed Brugada pattern and a history of palpitations without major events should be scheduled for risk stratification. Even though its value has been questioned, inducibility of VTs/VF at programmed electric stimulation is widely used to select candidates to receive a prophylactic implantable cardiac defibrillator in these categories. Herein, we report a patient with type I Electrocardiogram (ECG pattern induced at the Ajmaline test and a family history of sudden cardiac death who had episodes of palpitations. We describe and discuss our management proving the importance of complete electrophysiological testing in the setting of Brugada asymptomatic patients’ risk stratification.

    The role of possessing an abnormal body weight in the body image alterations of obese patients was evaluated in bariatric surgery subjects prior to and at long term after operation, when body weight and shape had become steadily normalized. Body image was assessed by the body dissatisfaction scale of the Eating Disorders Inventory, the Body Shape Questionnaire, and the Body Attitude Questionnaire. When the individuals were obese, a sharply impaired body image was observed; following operation, weight loss corresponded to normalization of body dissatisfaction, feeling of fatness, and physical attractiveness, whereas body disparagement and salience of shape, although improved in comparison to preoperative data, remained significantly different from that of controls. In the obese patients, some aspects of body image alterations are substantially accounted for by overweight status; other aspects reflect inner feelings, which are partially independent of the actual body weight and shape.

    Postoperative peritonitis (POP) is a common surgical complication after bariatric surgery (BS). We assessed the importance of positive fungal cultures in these cases of POP admitted to the intensive care unit. Clinical features and outcome were compared in 25 (41%) Candida-positive patients (6 (22%) fluconazole-resistant Candida glabrata) and 36 patients without Candida infection. Candida infections were more commonly isolated in late-onset peritonitis and were often associated with multidrug-resistant bacteria. Risk factors for intensive care unit mortality (19.6%) were diabetes and superobesity. Candida infections, including fluconazole-resistant strains, are common in POP after BS. These data encourage the empirical use of a broad-spectrum antifungal agent.

    Women with pre-existing abnormal glucose regulation are certain to develop gestational diabetes in pregnancy and pre-gestational type 2 diabetes will become more difficult to control. However, an increasing number of women with type 2 diabetes have had bariatric surgery. In this group, the effect of pregnancy on glucose metabolism is unknown. We report two women with type 2 diabetes who underwent laparoscopic gastric bypass surgery with normalization of plasma glucose levels. During subsequent pregnancy, maternal blood glucose levels remained completely normal throughout. This is remarkable given the predisposition to abnormal glucose tolerance and the ongoing obesity, in the face of the insulin resistance of pregnancy. Women with prior type 2 diabetes reversed by gastric bypass surgery are not at high risk for gestational diabetes.

  3. News media reports of patient deaths following 'medical tourism' for cosmetic surgery and bariatric surgery.

    Contemporary scholarship examining clinical outcomes in medical travel for cosmetic surgery identifies cases in which patients traveled abroad for medical procedures and subsequently returned home with infections and other surgical complications. Though there are peer-reviewed articles identifying patient deaths in cases where patients traveled abroad for commercial kidney transplantation or stem cell injections, no scholarly publications document deaths of patients who traveled abroad for cosmetic surgery or bariatric surgery. Drawing upon news media reports extending from 1993 to 2011, this article identifies and describes twenty-six reported cases of deaths of individuals who traveled abroad for cosmetic surgery or bariatric surgery. Over half of the reported deaths occurred in two countries. Analysis of these news reports cannot be used to make causal claims about why the patients died. In addition, cases identified in news media accounts do not provide a basis for establishing the relative risk of traveling abroad for care instead of seeking elective cosmetic surgery at domestic health care facilities. Acknowledging these limitations, the case reports suggest the possibility that contemporary peer-reviewed scholarship is underreporting patient mortality in medical travel. The paper makes a strong case for promoting normative analyses and empirical studies of medical travel. In particular, the paper argues that empirically informed ethical analysis of 'medical tourism' will benefit from rigorous studies tracking global flows of medical travelers and the clinical outcomes they experience. The paper contains practical recommendations intended to promote debate concerning how to promote patient safety and quality of care in medical travel. PMID:22420449

    Full Text Available Background The incidence of surgical site infection in bariatric patients is significant and the current recommendations for antibiotic prophylaxis are sometimes inadequate. Objective The aim of this study was to analyze the effect of three prophylactic antibiotic regimens on the incidence of surgical site infection. Methods A prospective, cross-sectional study was conducted between January 2009 and January 2013 in which 896 Roux-en-Y gastric bypasses were performed to treat obesity. The study compared three groups of patients according to the perioperative antibiotic prophylaxis administered intravenously and beginning at anesthesia induction: Group I consisting of 194 patients treated with two 3-g doses of ampicillin/sulbactam; Group II with 303 patients treated with a single 1-g dose of ertapenem; and Group III with 399 patients treated with a 2-g dose of cefazolin at anesthesia induction followed by a continuous infusion of cefazolin 1g throughout the surgical procedure. The rate of surgical site infection was analyzed, as well as its association with age, sex, preoperative weight, body mass index and comorbidities. Results The rates of surgical site infection were 4.16% in the group treated prophylactically with ampicillin/sulbactam, 1.98% in the ertapenem group and 1.55% in the continuous cefazolin group. Conclusion The prophylactic use of continuous cefazolin in surgeries for morbid obesity shows very promising results. These findings suggest that some prophylactic regimens need to be reconsidered and even substituted by more effective therapies for the prevention of surgical site infections in bariatric patients.

    Full Text Available Bariatric surgery developed in the late 1970 to treat severe hyperlipidemias in overweight individuals, not necessarily obese. Several techniques have been developed, and the concept has come first of a surgery for morbid obesity, then of a cure for diabetes in morbid obesity. There are other aspects of bariatric surgery that deserve attention, beyond BMI and diabetes, such as hypertension, poor life expectancy, increased prevalence of cancer, congestive heart failure, social inadequacy. The aim of this presentation is to review some recent development in clinical research, in the fields of liver steatosis, ferritin metabolism, and cholesterol metabolism. Liver steatosis, also called fatty liver encompasses a graduation of diseases with different clinical relevance and prognosis. NAFLD correlates with atherosclerosis, insulin resistance and diabetes mellitus. There is now evidence that weight loss, obtained through diet or restrictive surgery, reduces the prevalence (and the severity of NAFLD. An other issue is represented by serum ferritin concentrations, that are strongly associated with fibrosis, portal and lobular inflammation in NAFLD patients, especially in the presence of obesity. Body iron contributes to excess oxidative stress already at non iron overload concentrations. Moreover, serum ferritin is an important and independent predictor of the development of diabetes. Weight loss is accompanied by reduction of ferritin, more after restrictive than malabsorptive surgery. Metabolic changes are greater after malabsorptive or mixed surgery than after purely restrictive surgery, and this has been ascribed to a greater weight loss. Studies comparing the two kinds of surgery indicate that, for the same amount of weight loss, decrease of cholesterol is greater with the former than with the latter techniques, and this difference is mainly due to a greater reduction of intestinal absorption of cholesterol.

    Full Text Available Background: Very few studies have been performed on small populations about the links between employment and bariatric surgery.Objective: To determine if rates of employment are increased among patients who have undergone bariatric surgery, to assess their post-operative health consequences (post-prandial weakness, diarrhea, and patients' ability to maintain post-operative advice (ie, 30 minutes of daily physical activity, 6 small meals daily compared to non-employed post-surgical patients.Methods: This cross-sectional study was performed in the Regional Reference Centre for Obesity, which is a partnership between the University Hospital and a clinic in Angers, France during 2012 using a self-administrated questionnaire completed by patients hospitalized for post-operative follow-ups after bariatric surgery. Issues investigated were their professional situation before and after the surgery, compliancy to post-operative advice, and any postoperative side effects.Results: Employment rates were 64.4% before and 64.7% after the surgery (p=0.94. Of these, 30.6% maintained 30 minutes of daily physical activity vs. 41.0% of non-workers (p=0.02. 50.5% of employed patients and 57.3% of non-workers maintained 6 small meals a day after surgery (p=0.09. 8% of working patients reported post-prandial weaknesses and 8% reported diarrhea that caused problems at work.Conclusion: Employment rate remained stable after surgery. Having a job seemed to be an obstacle to managing 30 minutes of daily exercise, especially among women, but not maintaining 6 small meals a day. Therefore, working environment needs to be assessed to improve job quality and retention for patients who have undergone bariatric surgery.

    Obesity and insulin resistance are associated with altered brain glucose metabolism. Here, we studied brain glucose metabolism in 22 morbidly obese patients before and 6 months after bariatric surgery. Seven healthy subjects served as control subjects. Brain glucose metabolism was measured twice per imaging session: with and without insulin stimulation (hyperinsulinemic-euglycemic clamp) using [18F]fluorodeoxyglucose scanning. We found that during fasting, brain glucose metabolism was not dif...

    2016-03-01

    Full Text Available Esophagogastroduodenoscopy (EGD is regarded as a relatively safe procedure; however, it carries a very low incidence of severe adverse events. Perforation is a rare complication of EGD, and it may further lead to pneumoperitoneum or pneumoretroperitoneum. The occurrence of large bowel perforation after EGD is extremely rare, and it has never been reported in the international literature. Herein, we present a case of concurrence of pneumoperitoneum and pneumoretroperitoneum as a result of sigmoid perforation after EGD. In our case, the probable mechanism of the perforation may have stemmed from the excessive inflation of air that passed through the gastrointestinal tract to the sigmoid colon, causing the increased intraluminal pressure, and then prompting a healed asymptomatic diverticulitis leak again.

    Full Text Available Bladder leiomyomas are rare benign mesenchymal tumors, which account for less than 0.43% of all bladder tumors with approximately 200 cases described in the literature. These tumors may be classified into 3 different locations: endovesical, intramural and extravesical. Endovesical is the most common form, accounting for 63-86% of the cases, while intramural occurs in 3-7% and extravesical in 11-30%. The intramural form, especially small tumors, may not produce symptoms hardening detection. We report two cases of intramural bladder leiomyomas in asymptomatic men observed incidentally by transabdominal ultrasonography during the follow-up of benign prostatic hyperplasia. We discuss the diagnosis and management of these lesions.

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

    Full Text Available Abstract Objective Behcet's is an idiopathic multi-organ syndrome, which may have onset during childhood. Vascular involvement is uncommon, with rarely reported coronary aneurysm formation. We present a case report of a teenager girl who developed recalcitrant life-threatening Behcet's vasculitis, involving both small and large venous and arterial systems including a giant coronary aneurysm. Case report De-identified data were collected retrospectively in case report format. Although our sixteen year old female with Behcet's vasculitis had resolution of many arterial aneurysms, she had persistent venous thrombosis of large vessels, as well as persistent, giant arterial aneurysms requiring intra-arterial coiling of a lumbar artery and coronary bypass grafting despite intensive immunosuppression including glucocorticoids, cyclophosphamide, infliximab, methotrexate, azathioprine and intravenous immunoglobulin. Conclusions Vascular manifestations may be seen in Behcet's syndrome, including asymptomatic coronary aneurysm, which may be refractory to immunosuppression and ultimately require surgical intervention. Increased awareness is essential for prompt diagnosis and management.

    Transthyretin familial amyloid polyneuropathy (TTR-FAP) is a rare, severe, and irreversible, adult-onset, hereditary disorder caused by autosomal-dominant mutations in the TTR gene that increase the intrinsic propensity of transthyretin protein to misfold and deposit systemically as insoluble amyloid fibrils in nerve tissues, the heart, and other organs. TTR-FAP is characterized by relentless, progressively debilitating polyneuropathy, and leads to death, on average, within 10 years of symptom onset without treatment. With increased availability of disease-modifying treatment options for a wider spectrum of patients with TTR-FAP, timely detection of the disease may offer substantial clinical benefits. This review discusses mutation-specific predictive genetic testing in first-degree relatives of index patients diagnosed with TTR-FAP and the structured clinical follow-up of asymptomatic gene carriers for prompt diagnosis and early therapeutic intervention before accumulation of substantial damage.

    Brain check-up was performed in 4000 healthy subjects who underwent medical and radiological examinations for possible brain diseases in our hospital from April 1996 to March 2000. Magnetic resonance imaging revealed 11 brain tumors which consisted of six meningiomas, three pituitary adenomas, one astrocytoma, and one epidermoid cyst. The detection rate of incidental brain tumor in our hospital was 0.3%. Nine patients underwent surgery, with one case of morbidity due to postoperative transient oculomotor nerve paresis. The widespread use of brain check-up may increasingly detect asymptomatic brain tumors. Surgical indications for such lesions remain unclear, and the strategy for treatment should be determined with consideration of the patient's wishes. (author)

    A 53-year old previously healthy male underwent a screening colonoscopy for detection of a potential colorectal neoplasm. The terminal ileum was intubated and a mass was noted. Examination of the colon was normal. The biopsy of the ileal mass was consistent with an adenocarcinoma arising from the terminal ileum. His father who had never been previously ill from gastrointestinal disease died of natural causes,but was found to have Crohn's disease postmortem.The patient underwent exploratory laparotomy and aright hemicolectomy with a 30 cm section of terminal ileum in continuity. Findings were consistent with ileal adenocarcinoma in the setting of Crohn's disease. Thepatient made an uneventful recovery. The pathology was stage 1 adenocarcinoma. This is a unique case in that on a screening colonoscopy, a favorable ileal adenocarcinoma was discovered in the setting of asymptomatic, undiagnosed ileal Crohn's disease in a patient whose father had Crohn's disease diagnosed postmortem.

    Many papers in the medical literature analyze the cost-effectiveness of screening for diseases by comparing a limited number of a priori testing policies under estimated problem parameters. However, this may be insufficient to determine the best timing of the tests or incorporate changes over time. In this paper, we develop and solve a Markov Decision Process (MDP) model for a simple class of asymptomatic diseases in order to provide the building blocks for analysis of a more general class of diseases. We provide a computationally efficient method for determining a cost-effective dynamic intervention strategy that takes into account (i) the results of the previous test for each individual and (ii) the change in the individual’s behavior based on awareness of the disease. We demonstrate the usefulness of the approach by applying the results to screening decisions for Hepatitis C (HCV) using medical data, and compare our findings to current HCV screening recommendations.

    Full Text Available Cholecystocolonic fistulas (CCF are rare complications of gallstones with a variable clinical presentation. Despite modern diagnostic tools, cholecystocolonic fistulas are often asymptomatic and it is difficult to diagnose them preoperatively. Biliary-enteric fistulae have been found in 0.9% of patients undergoing biliary tract surgery. The most common site of communication of the fistula is the cholecystoduodenal (70%, followed by the cholecystocolic (10–20%, and the least common is the cholecystogastric fistula. Herein, we report a case of female patient with multiple episodes of acute recurrent cholangitis due to common bile duct and gallbladder stones in which preoperative imaging studies were negative for cholecystocolonic fistula that was incidentally discovered and treated during surgery and was appropriately treated. A review of the literature is reported too.

    Full Text Available Background: Several reports have described worse perioperative outcomes of laparoscopic gastric bypass procedure during learning curve, which improved after completion of one-year fellowship training. Aims: The aim of this study was to evaluate the immediate impact of fellowship training on perioperative complications and outcomes of various bariatric procedures. Materials and Methods: One hundred initial patients who underwent laparoscopic gastric banding, laparoscopic Roux-en-Y gastric bypass, laparoscopic vertical sleeve gastrectomy, and robotically-assisted laparoscopic biliopancreatic diversion with duodenal switch by a single fellowship trained surgeon were analyzed. Results: Overall average Body Mass Index (BMI of the patients was 45.9 kg/m 2 , age was 47.5 years, and the American Society of Anesthesiologist Score was 2.89. There were no intraoperative, major 30-day complications, or open conversions. Average operative time was 62 minutes in gastric banding, 160 minutes in gastric bypass, 119 minutes in vertical sleeve gastrectomy, and 320 minutes in biliopancreatic diversion. Length of stay ranged from 0.5 day after gastric banding to 3.9 days after biliopancreatic diversion. The perioperative complications and outcomes are comparable with those reported by experienced surgeons. No mortality occurred in this series. Conclusions: Bariatric fellowship ensured skills acquisition for new surgeons to safely and effectively perform various types of bariatric operations, with minimal perioperative complications and excellent outcomes.

    Full Text Available BACKGROUND AND OBJECTIVE: To investigate the influence of intraoperative and preoperative positive pressure in the time of extubation in patients undergoing bariatric surgery. METHOD: Randomized clinical trial, in which 40 individuals with a body mass index between 40 and 55 kg/m2, age between 25 and 55 years, nonsmokers, underwent bariatric surgery type Roux-en-Y gastric bypass by laparotomy and with normal preoperative pulmonary function were randomized into the following groups: G-pre (n = 10: individuals who received treatment with noninvasive positive pressure before surgery for 1 h; G-intra (n = 10: individuals who received positive end-expiratory pressure of 10 cm H2O throughout the surgical procedure; and G-control (n = 20: not received any preoperative or intraoperative intervention. Following were recorded: time between induction of anesthesia and extubation, between the end of anesthesia and extubation, duration of mechanical ventilation, and time between extubation and discharge from the post-anesthetic recovery. RESULTS: There was no statistical difference between groups. However, when applied to the Cohen coefficient, the use of positive end-expiratory pressure of 10 cm H2O during surgery showed a large effect on the time between the end of anesthesia and extubation. About this same time, the treatment performed preoperatively showed moderate effect. CONCLUSION: The use of positive end-expiratory pressure of 10 cm H2O in the intraoperative and positive pressure preoperatively, influenced the time of extubation of patients undergoing bariatric surgery.

    Objective. Obesity is a risk factor for hypogonadotropic hypogonadism in men. Weight loss has been shown to improve hypogonadism in obese men. This study evaluated the early changes in sex hormones profile after bariatric surgery. Methods. This is a prospective study including 29 morbidly obese men. Main outcomes were changes in serum levels of total testosterone (TT), free testosterone (cFT), SHBG, estradiol, adiponectin, and leptin at 1 and 6 months after surgery. Results. The mean age of patients was 31 ± 8 years and the mean BMI was 56.8 ± 11.7 kg/m2. Fifteen patients underwent Roux-en-Y gastric bypass and 14 patients underwent sleeve gastrectomy. At baseline, 22 patients (75.9%) had either low TT levels (<10.4 nmol/L) or low cFT levels (<225 pmol/L). Total testosterone and SHBG levels increased significantly at 1 month after surgery (p ≤ 0.001). At 6 months after surgery, TT and cFT increased significantly (p ≤ 0.001) and 22 patients (75.9%) had normalized TT and cFT levels. There were no changes in estradiol levels at either 1 month or 6 months after surgery. Conclusions. Increases in TT and SHBG levels occurred early at 1 month after bariatric surgery while improvements in cFT levels were observed at 6 months after bariatric surgery.

    Background: Because of growing body of interest on the association between fibrosing idiopathic interstitial pneumonias (f-IIP) and ischaemic heart disease, we initiated this prospective study to evaluate the prevalence of asymptomatic coronary artery disease (CAD) in patients with f-IIP. Methods: Forty-two patients with f-IIP underwent noninvasive screening for CAD that included (a) a chest CT examination enabling calculation of the coronary artery calcium (CAC) score, then depiction of coronary artery stenosis; and (b) stress myocardial perfusion scintigraphy (MPS). Patients with significant coronary abnormalities, defined by a CAC score >400 or coronary artery stenosis >50% at CT and/or perfusion defect >5% at MPS, were referred to the cardiologist. Coronary angiography was indicated in presence of a perfusion defect >10% at MPS or significant left main or proximal left anterior descending stenosis whatever MPS findings. Results: Combining CT and MPS, significant abnormalities were detected in 32/42 patients (76%). The cardiologist: (a) did not consider further investigation in 21 patients (CT abnormalities but no ischaemia at MPS: 12/21; false-positive findings at MPS: 3/21; poor respiratory condition: 6/21); (b) proceeded to coronary angiography in 11 patients which confirmed significant stenoses in 5 patients (5/42; 12%). In the worst-case-scenario (i.e., inclusion of 6 patients with significant coronary artery abnormalities who were not investigated due to poor respiratory condition), the prevalence of CAD reached 26% (11/42). Conclusion: In the studied population of patients with f-IIP, asymptomatic CAD ranged between 12% and 26%.

    Management guidelines were created to screen and manage asymptomatic renal stones in U.S. astronauts. The true risk for renal stone formation in astronauts due to the space flight environment is unknown. Proper management of this condition is crucial to mitigate health and mission risks. The NASA Flight Medicine Clinic electronic medical record and the Lifetime Surveillance of Astronaut Health databases were reviewed. An extensive review of the literature and current aeromedical standards for the monitoring and management of renal stones was also done. This work was used to develop a screening and management protocol for renal stones in astronauts that is relevant to the spaceflight operational environment. In the proposed guidelines all astronauts receive a yearly screening and post-flight renal ultrasound using a novel ultrasound protocol. The ultrasound protocol uses a combination of factors, including: size, position, shadow, twinkle and dispersion properties to confirm the presence of a renal calcification. For mission-assigned astronauts, any positive ultrasound study is followed by a low-dose renal computed tomography scan and urologic consult. Other specific guidelines were also created. A small asymptomatic renal stone within the renal collecting system may become symptomatic at any time, and therefore affect launch and flight schedules, or cause incapacitation during a mission. Astronauts in need of definitive care can be evacuated from the International Space Station, but for deep space missions evacuation is impossible. The new screening and management algorithm has been implemented and the initial round of screening ultrasounds is under way. Data from these exams will better define the incidence of renal stones in U.S. astronauts, and will be used to inform risk mitigation for both short and long duration spaceflights.

    AIM: To evaluate the prevalence and clinical characteristics of Nonalcoholic fatty liver disease (NAFLD) among asymptomatic Brazilian adolescents.METHODS: Transversal observational study included asymptomatic adolescents with central obesity from private and public schools in Salvador-Bahia, northeastern Brazil. The children answered a questionnaire that included age, gender, race, and medical history, and were submitted to a complete physical exam and abdominal ultrasound. Biochemical exams included: ALT, AST, GGT,C reactive protein (CRP), fasting glucose, insulin, cholesterol and triglycerides. Criteria for NAFLD included: the presence of steatosis in ultrasound and/or high level of ALT, negative or occasional historic of intake of alcohol (≤ 140 g/wk), negative investigation for hepatitis A, B, C,auto-immune hepatitis, Wilson disease and hemochromatosis.RESULTS: From October, 2005 to October, 2006, the study included 1801 subjects between 11 and 18 years of age and a mean age of 13.7±2.0 years.One hundred ninety-nine had central obesity. The prevalence of NAFLD was 2.3%, most of whom were male and white. Insulin resistance (IR) was observed in 22.9% of them and had positive correlations with ALT and GGT ( P < 0.05). Elevated CRP was observed in 6.9% of the cases; however, it was not associated with WC,IR or liver enzymes.CONCLUSION: The prevalence of NAFLD in Brazilian adolescents was low. The ethnicity may have influence this frequency in the population studied, which had a large proportion of African descendents.

    Full Text Available Prevalence of asymptomatic carotid artery stenosis in patients with lower extremities atherosclerosis is relatively high. Limiting screening of specific subgroups for any demographic or medical characteristics is ineffective. Screening for asymptomatic carotid artery stenosis is indicated in all patients with lower extremities atherosclerosis except in whom prophylactic carotid endarterectomy is not recommended because of comorbid disease or extreme age.

    Clostridium difficile is well recognized as the common pathogen of nosocomial diarrhea, meanwhile, asymptomatic colonization with C. difficile in part of the population has also drawn public attention. Although gut microbiota is known to play an important role in the pathogenesis of C. difficile infection (CDI), whether there is any alteration of gut microbial composition in asymptomatic C. difficile carriers hasn't been clearly described. The purpose of this study was to explore the differences in gut microbiome among CDI patients, asymptomatic C. difficile carriers and healthy individuals. We performed fecal microbiota analysis on the samples of eight CDI patients, eight asymptomatic C. difficile carriers and nine healthy subjects using 16S rRNA gene pyrosequencing. CDI patients and asymptomatic carriers showed reduced microbial richness and diversity compared with healthy subjects, accompanied with a paucity of phylum Bacteroidetes and Firmicutes as well as an overabundance of Proteobacteria. Some normally commensal bacteria, especially butyrate producers, were significantly depleted in CDI patients and asymptomatic carriers. Furthermore, the differences observed in microbial community structure between CDI patients and asymptomatic carriers suggested that the gut microbiota may be a potential factor of disease state for CDI. Our study demonstrates the characterization and diversity of gut microbiota in CDI and asymptomatic C. difficile colonization, which will provide new ideas for surveillance of the disease state and development of microbiota-targeted agents for CDI prevention and treatment.

    International Nuclear Information System (INIS)

    Aim: To assess the diagnostic value of coronary dual-source computed tomography (DSCT) as a comprehensive, non-invasive tool in the preoperative cardiac evaluation of patients undergoing bariatric surgery. Materials and methods: Thirty consecutive obese [average body mass index (BMI): 45 ± 7.6, range: 35–59] patients (24 women; six men; median age: 52 ± 15 years) were enrolled in this institutional review board (IRB)-approved, Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant prospective study. Calcium scoring (CaS) and electrocardiography (ECG)-gated images of the coronary arteries were obtained with a large body habitus protocol (120 kV; 430 mAs; 100 ml iodinated contrast medium at 7 ml/s injection rate) on a DSCT machine. Qualitative (four-point: 1 = excellent to 4 = not delineable) coronary segmental analysis, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) measurements were performed. The presence and degree of vascular disease (four-grade scale: mild to severe) was correlated with CaS and cardiovascular (CV) risk stratification blood tests. In patients with severe stenosis (>70%), findings were compared with cardiac nuclear medicine imaging (single photon-emission computed tomography; SPECT) imaging. Results: The average HR, enhancement, and quality score were 64 ± 7 beats/min, 288 ± 66 HU and 1.8 ± .5, respectively. Ninety-three percent (417/450) of the coronary segments were rated diagnostic. The SNRs and CNRs were 17 ± 9 and 12 ± 7 for the right coronary artery; 17 ± 8 and 12 ± 7 for the left main coronary artery; 16 ± 9 and 11 ± 7 for the left anterior descending coronary artery; and 15 ± 7 and 10 ± 6 for the left circumflex coronary artery. Ten of the 30 patients (33%) demonstrated coronary artery disease (CAD) of which two (6%) showed three-vessel disease. Four (13%) patients showed severe disease: in three of which the presence of significant stenosis was confirmed by SPECT and by catheter

    Full Text Available A quantitative real time polymerase chain reaction (PCR revealed canine distemper virus presence in peripheral blood samples from asymptomatic and non vaccinated dogs. Samples from eleven domestic dogs with no signs of canine distemper and not vaccinated at the month of collection were used. Canine distemper virus vaccine samples in VERO cells were used as positive controls. RNA was isolated with Trizol®, and treated with a TURBO DNA-free kit. Primers were designed for canine distemper virus nucleocapsid protein coding region fragment amplification (84 bp. Canine b-actin (93 bp was utilized as the endogenous control for normalization. Quantitative results of real time PCR generated by ABI Prism 7000 SDS Software showed that 54.5% of dogs with asymptomatic canine distemper were positive for canine distemper virus. Dissociation curves confirmed the specificity of the real time PCR fragments. This technique could detect even a few copies of viral RNA and identificate subclinically infected dogs providing accurate diagnosis of this disease at an early stage.A reação em cadeia da polimerase (PCR em tempo real revelou a presença do vírus da cinomose canina em amostra de sangue de cães assintomáticos e não vacinados.

    K Abigail Andrews

    Full Text Available There is considerable interest in designing therapeutic studies of individuals at risk of Alzheimer disease (AD to prevent the onset of symptoms. Cortical β-amyloid plaques, the first stage of AD pathology, can be detected in vivo using positron emission tomography (PET, and several studies have shown that ~1/3 of healthy elderly have significant β-amyloid deposition. Here we assessed whether asymptomatic amyloid-PET-positive controls have increased rates of brain atrophy, which could be harnessed as an outcome measure for AD prevention trials. We assessed 66 control subjects (age = 73.5±7.3 yrs; MMSE = 29±1.3 from the Australian Imaging Biomarkers & Lifestyle study who had a baseline Pittsburgh Compound B (PiB PET scan and two 3T MRI scans ~18-months apart. We calculated PET standard uptake value ratios (SUVR, and classified individuals as amyloid-positive/negative. Baseline and 18-month MRI scans were registered, and brain, hippocampal, and ventricular volumes and annualized volume changes calculated. Increasing baseline PiB-PET measures of β-amyloid load correlated with hippocampal atrophy rate independent of age (p = 0.014. Twenty-two (1/3 were PiB-positive (SUVR>1.40, the remaining 44 PiB-negative (SUVR≤1.31. Compared to PiB-negatives, PiB-positive individuals were older (76.8±7.5 vs. 71.7±7.5, p<0.05 and more were APOE4 positive (63.6% vs. 19.2%, p<0.01 but there were no differences in baseline brain, ventricle or hippocampal volumes, either with or without correction for total intracranial volume, once age and gender were accounted for. The PiB-positive group had greater total hippocampal loss (0.06±0.08 vs. 0.02±0.05 ml/yr, p = 0.02, independent of age and gender, with non-significantly higher rates of whole brain (7.1±9.4 vs. 4.7±5.5 ml/yr and ventricular (2.0±3.0 vs. 1.1±1.0 ml/yr change. Based on the observed effect size, recruiting 384 (95%CI 195-1080 amyloid-positive subjects/arm will provide 80% power to detect 25

  18. Role of myocardial perfusion SPECT in asymptomatic diabetic patients

    International Nuclear Information System (INIS)

    Purpose: It is important that early diagnosis and treatment of coronary artery disease in diabetic patients, but there are few reports on the prevalence of stress-induced myocardial perfusion abnormalities and the rates of cardiac event in patients with type 2 diabetes. We evaluated the scan findings on gated myocardial perfusion SPECT in asymptomatic diabetic patients. Methods: We performed pharmacological stress test and gated perfusion SPECT in 69 diabetic patients without cardiovascular symptom (mean age: 65 year, male 31 and female 38). Patients underwent two-day imaging protocol and stress study was performed injection of Tc-99m MIBI during adenosine infusion. We followed up these patients by reviewing medical records. Results: Fifty-two of 69 patients (74.5%) showed normal scan findings and 17 patients (24.6%) showed reversible or fixed perfusion defects. Three of 52 patients with normal scan findings showed decreased LV ejection fraction and decreased wall motion. Twenty-three patients with normal scan findings were possible to follow up for more than 1yr (mean time: 18.3±3.3 mo.) and they all had no cardiac event. Three patients with reversible perfusion defects were performed coronary angioplasty. Conclusion: Myocardial perfusion SPECT is a noninvasive method and maybe useful in early diagnosis and predicting prognosis in diabetic patients

    Breast density (BD) is a risk factor for breast cancer. Aims. To describe BD patterns in asymptomatic Mexican women and the pathological mammographic findings. Methods and Material. Prospective, descriptive, and comparative study. Women answered a questionnaire and their mammograms were analyzed according to BI-RADS. Univariate (X2) and conditional logistic regression analyses were performed. Results. In 300 women studied the BD patterns were fat 56.7% (170), fibroglandular 29% (87), heterogeneously dense 5.7% (17), and dense pattern 8.6% (26). Prevalence of fat pattern was significantly different in women under 50 years (37.6%, 44/117) and older than 50 (68.8%, 126/183). Patterns of high breast density (BD) (dense + heterogeneously dense) were observed in 25.6% (30/117) of women ≤50 years and 7.1% (13/183) of women >50. Asymmetry in BD was observed in 22% (66/300). Compression cone ruled out underlying disease in 56 cases. In the remaining 10, biopsy revealed one fibroadenoma, one complex cyst, and 6 invasive and 2 intraductal carcinomas. 2.6% (8/300) of patients had non-palpable carcinomas. Benign lesions were observed in 63.3% (190/300) of cases, vascular calcification in 150 cases (78.9%), and fat necrosis in 38 cases (20%). Conclusions. Mexican women have a low percentage of high-density patterns

    Full Text Available Acute stroke manifesting as focal neurological deficit is a leading cause of death and disability. Of interest is the problem of asymptomatic cerebral infarctions (AСI, in which there is focal medullary involvement unaccompanied by the development of focal symptoms. The role of AСI as a marker for the progression of vascular dementia and for the further development of symptomatic stroke has not been adequately explored. There are current instrumental (neuroimaging criteria for diagnosing AСI. An update on the risk factors of AСI and their association with the further course of cerebrovascular involvement is analyzed. The results of a number of prospective studies conducted in the countries of Asia and Europe to investigate risk factors for AСI and their prognostic value are considered in detail. There is a relationship between hypertension, blood pressure instability, type 2 diabetes mellitus, some other factors, and a significantly increased risk for AСI. Based on the results of analyzing the data available in the literature, the authors demonstrate the association of prior AСI with the higher rates of progressive vascular cognitive impairments. A correlation is shown between prior AСI and an increased risk for further development of ischemic stroke accompanied by its clinical symptoms, which leads to disability. It is suggested that it is advisable to implement measures for secondary cardiovascular disease prevention, including the administration of antiaggregatory and antihypertensive agents, in patients with AСI.

    Blood donor screening for hepatitis C virus (HCV) antibodies is now routine. Most blood transfusion services recommend that seropositive donors are referred for further investigation. Southern European studies suggest that many asymptomatic seropositive donors have clinically significant liver disease. Seropositive donors in areas of high prevalence may not, however, be representative of British donors. We have prospectively examined the prevalence and severity of HCV infection in a British volunteer blood donor population. During a 14 month period, only 0.35% (999/287,332) of all donors in the West Midlands were anti-HCV (screening assay) positive. Only 5% (52/999) of these were confirmed true seropositive. Nearly 80% (41/52) of seropositive donors were referred to the Queen Elizabeth Hospital Liver Unit for further investigation. Most underwent complete investigation, including liver biopsy. Forty of forty-one donors had biochemical, histological, or virological evidence of persistent viral infection. Histological changes were generally mild and none was cirrhotic. Covertly infected patients had less severe disease than those with an overt risk factor for HCV exposure. In the British Midlands, the prevalence of blood donor seropositivity is low. In contrast with seropositive Southern European donors, the British donor is more likely to belong to an at-risk group for parenteral exposure and is less likely to have severe histological changes. This study highlights the importance of developing locally relevant guidelines for the counselling and investigation of anti-HCV-positive blood donors. PMID:7493294

  5. Use of spirometry in detecting airway obstruction in asymptomatic smokers

    International Nuclear Information System (INIS)

    Objectives: To detect spirometric abnormalities in asymptomatic smokers in relation to duration of smoking. Study Design: Cross sectional study. Place and Duration of Study: The study was carried out at PNS Shifa from Oct 2006 to June 2007. Subjects and Methods: Hundred individuals were included in this study who fulfilled the required criteria. Spirometry was done after briefing the patient about the procedure. Smokers were divided into two groups. Group I (5 to 9 pack years) and group II (= 10 pack years). All relevant information were recorded on Performa (Annex-A). The data was analyzed through SPSS-10, in terms of Mean +- SD (Standard Deviation) for numeric response variables and independent sample T test was applied to compare significance of proportion for numeric response variables at p < 0.05. Categorical variables were compared by applying Chi-square test at p < 0.05 level of significance. Results: Significant statistical difference was found between the mean age in the two groups with p-value of 0.011. This may be due to the longer duration of smoking history in Group II. Strong association was found between number of cigarette smoked and the pattern of airway obstruction as significant statistical difference of airway obstruction and early airflow limitation was found between the two groups of smokers at p value of 0.004. Conclusion: There is strong association between duration of smoking and development of airway obstruction even before the smoker become symptomatic. (author)

    Full Text Available Objective To understand the process by which an obese woman decides to have bariatric surgery. Method A qualitative survey with a social phenomenology approach, carried out in 2012, with 12 women, using the phenomenological interview. Results A woman bases the decision to have the surgery on: the inappropriateness of her eating habits; a physical appearance that is incompatible with an appearance that is standardized by society; the social prejudice that she has to live with; the limitations imposed by obesity; and her lack of success with previous attempts to lose weight. Outcomes that she hopes for from the decision to have the surgery include: restoring her health; achieving social inclusion; and entering the labor market. Conclusion This study allows one to reflect that prescriptive actions do not give a satisfactory response to a complexity of the subjective questions involved in the decision to have surgery for obesity. For this, what is called for is a program of work based on an interdisciplinary approach, and training that gives value to the bio-psycho-social aspects involved in a decision in favor of surgical treatment.

    Bariatric (weight loss) surgery is the gold standard treatment for severe obesity. Concern exists that patients are regaining weight in the longer term. Success and cost-effectiveness of surgery are threatened due to the re-emergence of related conditions such as diabetes. This exploratory qualitative study investigates patients' expectations and experiences of weight regain (WR) 2 years or more after Roux-en-Y gastric bypass (RYGB). Ten participants (two men and eight women) who experienced WR were interviewed between 2 and 6 years following surgery. Findings highlight that participants reacted to initial weight loss as passive spectators and were unprepared for subsequent WR. Their tolerability of WR reduced as the amount of regain increased, suggesting a 'line of tolerance' for WR. WR was influenced by a new vulnerability arising from weight loss over time, and participants struggled to manage their own weight actively as surgical effects waned. They considered self-management skills, and carer and professional support to be limited at the time when WR was most likely to occur. Degrees of tolerability are noted in individuals regaining weight after RYGB. More studies are needed to further understand these problems. Pre- and post-operative support and teaching patients self-management skills may be helpful to minimize WR. PMID:27273813

    Full Text Available Background. Maternal obesity, excess weight gain and overnutrition during pregnancy increase risks of obesity, type 2 diabetes mellitus, and cardiovascular disease in the offspring. Maternal biliopancreatic diversion is an effective treatment for severe obesity and is beneficial for offspring born after maternal surgery (AMS. These offspring exhibit lower severe obesity prevalence and improved cardiometabolic risk factors including inflammatory marker compared to siblings born before maternal surgery (BMS. Objective. To assess relationships between maternal bariatric surgery and the methylation/expression of genes involved in the immune and inflammatory pathways. Methods. A differential gene methylation analysis was conducted in a sibling cohort of 25 BMS and 25 AMS offspring from 20 mothers. Following differential gene expression analysis (23 BMS and 23 AMS, pathway analysis was conducted. Correlations between gene methylation/expression and circulating inflammatory markers were computed. Results. Five immune and inflammatory pathways with significant overrepresentation of both differential gene methylation and expression were identified. In the IL-8 pathway, gene methylation correlated with both gene expression and plasma C-reactive protein levels. Conclusion. These results suggest that improvements in cardiometabolic risk markers in AMS compared to BMS offspring may be mediated through differential methylation of genes involved in immune and inflammatory pathways.

    Full Text Available Obesity is an important nutritional deviation that is exponentially increasing in Brazil and in the world, becoming a public health problem. The World Health Organization verified in 2005 that 1.6 billion people above 15 years old were overweight and 400 million were obese. Among children, 20 million were overweight. Amongst the different treatments for the obesity the bariatric surgery has been used very often nowadays, for being effective against weight excess and associated co-morbidities, both for the adult and youngster populations. The surgical techniques are divided in restrictive, disabsorptive and mixed procedures. Each technique promotes digestive and absorptive distinct alterations, needing, therefore, an exclusive multidisciplinary educational program, directed both to pre and postsurgery periods, emphasizing the habits of physical activity and the necessity to adhere to the restricted dietary recommendations. The surgeries promote a severe reduction in the consumption, which induces to the ingestion of diets that are hypocaloric and deficient in micronutrients, with consequent nutritional complications.

Clinical treatment modalities for this disease are limited and ineffective when it comes to morbidly obese patients (body mass index – the weight in kilograms divided by height in meters squared – surpasses 40 kg/m2. Therefore, the alternative, surgical treatment, is the best option for these patients, namely gastric restrictive procedures or an intestinal bypass culminating in a malabsorptive syndrome. In the past 20 years, there has been a 70% increase in the number of bariatric procedures all over the world. The main pharmacokinetic consequence observed in the postoperative period of these individuals is a higher or lower absorption of orally administered drugs.Keywords: anatomophysiological alterations, pharmacokinetic, obesity

    In this study, we unravel a molecular imaging marker correlated with the known reduction of cardiovascular events (most commonly related to vulnerable plaques) in morbidly obese patients after bariatric surgery (BaS).We prospectively imaged 10 morbidly obese subjects with F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography before and 1 year after BaS. F-FDG uptake-which is enhanced in inflamed, atherosclerotic vessels and in metabolically active adipose tissues-was quantified in the carotids, pericardial adipose tissue (PAT), visceral adipose tissue (VAT), as well as brown adipose tissue (BAT). The degree of carotid inflammation was compared to lean and overweight controls.Carotid inflammation significantly declined leading to an F-FDG uptake comparable to the 2 control groups. Metabolic activity significantly decreased in PAT and VAT and increased in BAT.BaS leads to a normalization of carotid artery inflammation and a beneficial impact on the metabolic activity in PAT, VAT, and BAT that is related to the metabolic syndrome observed in this patient group.

    AIM: To compare the performance of different types of abdominal drains used in bariatric surgery. METHODS: A vertical banded Roux-en-Y gastric bypass was performed in 33 morbidly obese patients. Drainage of the peritoneal cavity was performed in each case using three different types of drain selected in a randomized manner: a latex tubular drain, a Watterman tubulolaminar drain, and a silicone channeled drain. Drain permeability, contamination of the drained fluid, ease of handling, and patient discomfort were evaluated postoperatively over a period of 7 d. RESULTS: The patients with the silicone channeled drain had larger volumes of drainage compared to patients with tubular and tubulolaminar drains between the third and seventh postoperative days. In addition, a lower incidence of discomfort and of contamination with bacteria of a more pathogenic profile was observed in the patients with the silicone channeled drain.CONCLUSION: The silicone channeled drain was more comfortable and had less chance of occlusion, which is important in the detection of delayed dehiscence.

    Leishmania infantum is the etiologic agent of zoonotic visceral leishmaniasis (VL) in countries in the Mediterranean basin, where dogs are the domestic reservoirs and represent important elements in the transmission of the disease. Since the major focal areas of human VL exhibit a high prevalence of seropositive dogs, the control of canine VL could reduce the infection rate in humans. Efforts toward this have focused on the improvement of diagnostic tools, as well as on vaccine development. The identification of parasite antigens including suitable major histocompatibility complex (MHC) class I- and/or II-restricted epitopes is very important since disease protection is characterized by strong and long-lasting CD8+ T and CD4+ Th1 cell-dominated immunity. In the present study, total protein extract from late-log phase L. infantum promastigotes was analyzed by two-dimensional western blots and probed with sera from asymptomatic and symptomatic dogs. A total of 42 protein spots were found to differentially react with IgG from asymptomatic dogs, while 17 of these identified by Coommasie stain were extracted and analyzed. Of these, 21 proteins were identified by mass spectrometry; they were mainly involved in metabolism and stress responses. An in silico analysis predicted that the chaperonin HSP60, dihydrolipoamide dehydrogenase, enolase, cyclophilin 2, cyclophilin 40, and one hypothetical protein contain promiscuous MHCI and/or MHCII epitopes. Our results suggest that the combination of immunoproteomics and bioinformatics analyses is a promising method for the identification of novel candidate antigens for vaccine development or with potential use in the development of sensitive diagnostic tests.

    Objective. To determine the postoperative appearance of the plantar fascia on MR imaging after a fasciotomy has been performed, and to compare the postsurgical appearance of the fascia after an open and endoscopic procedure.< rate at head-abs-p1.lf>Design and patients. Fifteen asymptomatic volunteers (12 women, 3 men; age range 22-49 years, mean age 33 years) with prior fasciotomies for treatment of longstanding plantar fasciitis were studied. Fourteen volunteers had a unilateral release and one volunteer had bilateral releases, allowing for assessment of 16 ankles. Eight fasciotomies were performed through an open incision and eight were performed endoscopically. The average time between surgery and imaging was 24 months (range 11-46 months). The site of surgery was established from the operative reports. Proton density (PD)-weighted and T2-weighted images in three orthogonal planes were obtained on a 1.5-T magnet. In eight studies, T1-weighted sagittal and STIR sagittal images were included. The fascia in each ankle was assessed for morphology and signal intensity. Perifascial soft tissues and bone marrow were assessed for edema. Preoperative MR studies were available in five volunteers.< rate at head-abs-p1.lf>Results. There was no apparent difference in the postoperative appearance of the ankle after an open or endoscopic procedure except for scar formation in the subcutaneous fat which was common after an open procedure (P<0.05). Three ankles had a gap in the fascia (one open, two endoscopic). The plantar fascia measured a mean of 7.0 mm (range 5-10 mm) at the fasciotomy, and 8.3 mm (range 6-12 mm) at the enthesis. At the fasciotomy, 11 of 13 ankles had an indistinct deep contour and 9 of 13 had an indistinct superficial contour. At the enthesis, 13 of 16 ankles had an indistinct deep contour and 6 of 16 had an indistinct superficial contour. Compared with preoperative MR studies there was an average reduction in the fascial thickness at the enthesis of 14

    Various factors including severe obesity or increases in intra-abdominal pressure during laparoscopy can lead to inaccuracies in end-tidal carbon dioxide (PETCO2) monitoring. The current study prospectively compares ET and transcutaneous (TC) CO2 monitoring in severely obese adolescents and young adults during laparoscopic-assisted bariatric surgery. Carbon dioxide was measured with both ET and TC devices during insufflation and laparoscopic bariatric surgery. The differences between each measure (PETCO2 and TC-CO2) and the PaCO2 were compared using a non-paired t test, Fisher's exact test, and a Bland-Altman analysis. The study cohort included 25 adolescents with a mean body mass index of 50.2 kg/m2 undergoing laparoscopic bariatric surgery. There was no difference in the absolute difference between the TC-CO2 and PaCO2 (3.2±3.0 mmHg) and the absolute difference between the PETCO2 and PaCO2 (3.7±2.5 mmHg). The bias and precision were 0.3 and 4.3 mmHg for TC monitoring versus PaCO2 and 3.2 and 3.2 mmHg for ET monitoring versus PaCO2. In the young severely obese population both TC and PETCO2 monitoring can be used to effectively estimate PaCO2. The correlation of PaCO2 to TC-CO2 is good, and similar to the correlation of PaCO2 to PETCO2. In this population, both of these non-invasive measures of PaCO2 can be used to monitor ventilation and minimize arterial blood gas sampling.

    Full Text Available Background/Aim: Earlier reports from Saudi Arabia have shown high prevalence of Helicobacter pylori infection. However, recent studies have documented a reduction in the infection prevalence. No prior study has assessed the prevalence in morbidly obese Saudi patients. We aimed to study the prevalence of H. pylori infection in a group morbidly obese Saudi patients referred for endoscopy prior to bariatric surgery. Materials and Methods: We retrospectively reviewed the medical records of all patients who were referred for upper endoscopy prior to bariatric surgery from June 2006 to September 2008. All data were recorded including patient′s demographics, comorbid conditions, endoscopic and histological findings. Results: There were 62 patients included, 20 males and 42 females. The mean age was 34 years (range 18 - 51 with a mean BMI of 55 Kg/m 2 (range 35 -92. H. pylori were present in 53 patients (85.5% with chronic active gastritis. All patients with positive H. pylori had chronic gastritis of variable severity. Intestinal metaplasia was present in 5%. The prevalence of H. pylori infection was similar in patients with and without co-morbid conditions. Main endoscopic findings were gastritis in 67.7%, hiatus hernia in 13%, and gastric erosions in 13%. No patient had duodenal or gastric ulcer. Conclusions: There is a high prevalence of H. pylori infection in morbidly obese Saudi patients undergoing bariatric surgery being referred for upper GI endoscopy. Further prospective studies are needed to evaluate the clinical implication and benefit of eradication treatment of infection in these patients.

    Full Text Available Background. Sexual abuse may be associated with poorer weight loss outcomes following bariatric treatment. Identifying predictors of abuse would enable focused screening and may increase weight management success. Methods. We analyzed data from 500 consecutively recruited obese subjects from a population-based, regional bariatric program. The prevalence of self-reported sexual abuse was ascertained using a single interview question. Health status was measured using a visual analogue scale (VAS. Multivariable logistic regression was performed to identify sexual abuse predictors. Results. The mean age was 43.7 y (SD 9.6, 441 (88.2% were females, 458 (91.8% were white, and the mean body mass index (BMI was 47.9 kg/m2 (SD 8.1.

    Some authors claim that occlusal appliances can enhance athletic performance. Therefore, this study investigated the influence of dental occlusion on knee muscle strength performance. Twelve healthy female subjects (mean age, 24.1 ± 3.1 years) without temporomandibular joint dysfunction participated in this study. Isokinetic quadriceps and hamstring strength were assessed in relation to 3 randomized jaw conditions: mouth closed in maximum intercuspidation without splint, mouth closed on a balanced splint which optimized contact over the dental arch, mouth closed on a piece of resin of 1 mm which created an imbalanced occlusion. Tests were performed at 60 and 240°·s in concentric and 30°·s in eccentric exertions. Concentric performances did not show any significant difference between the 3 jaw conditions (p > 0.05). In contrast, in the eccentric trials related to quadriceps performance, significant differences (p ≤ 0.05) were observed between the resin condition and the 2 other modalities (without splint or with a balanced splint). The imbalanced occlusion created by the resin component corresponded to an average decrease of 9% in eccentric peak torque. The eccentric hamstring peak torques also showed a significant difference (p ≤ 0.05) between measurements with splint and with resin (7% decrease when occlusion was imbalanced). In conclusion, among asymptomatic females, artificial imbalanced occlusion induces immediate and significant alteration of knee eccentric muscle performances. Therefore, occlusion examination should be undertaken on a regular and frequent basis for high-level athletes. Moreover, for athletes using mouthguards, muscular performance assessments should be planned with and without the dental protection.

    Intradialytic hypotension (IDH) remains an important cause of morbidity and mortality in chronic hemodialysis (HD) patients and can be ameliorated by cool temperature HD. The baroreflex arc is under autonomic control and is essential in the short-term regulation of blood pressure (BP). This study aimed to investigate if the baroreflex sensitivity (BRS) response to HD differed between standard and cool-temperature dialysate. Ten patients (mean age 67+/-2 years) prone to IDH were recruited into a randomized, crossover study to compare BRS variation at dialysate temperatures of 37 degrees C (HD(37)) and 35 degrees C (HD(35)). Each patient underwent continuous beat-to-beat BP monitoring during a dialysis session of HD(37) and HD(35). During HD(37) 2 patients developed symptomatic IDH, as opposed to 1 with HD(35). However, asymptomatic IDH occurred with a frequency of 0.4 episodes per session with HD(35) and 6.2 episodes per session during HD(37) (odds ratio15.5; 95%CI 5.6-14.2). Although absolute BRS measurements did not differ between the 2 modalities, BRS variability increased during HD(35). Our study has demonstrated that in IDH-prone patients, cool HD resulted in a reduction in heart rate and a greater reduction in cardiac output and stroke volume. Mean arterial pressure was maintained through a significantly greater increase in total peripheral resistance. Furthermore, although absolute BRS values during HD were not significantly altered by a reduction in dialysate temperature, there was a greater percentage increase in BRS values during cool HD. Understanding the varied causes of, and categorizing impaired hemodynamic responses to HD will enable further individualization of HD prescriptions according to patient need.

    Purpose Interest in using T1 as a potential MRI biomarker of chronic obstructive pulmonary disease (COPD) has recently increased. Since tobacco smoking is the major risk factor for development of COPD, the aim for this study was to examine whether tobacco smoking, pack-years (PY), influenced T1 of the lung parenchyma in asymptomatic current smokers. Materials and Methods Lung T1 measurements from 35 subjects, 23 never smokers and 12 current smokers were retrospectively analyzed from an institutional review board approved study. All 35 subjects underwent pulmonary function test (PFT) measurements and lung T1, with similar T1 measurement protocols. A backward linear model of T1 as a function of FEV1, FVC, weight, height, age and PY was tested. Results A significant correlation between lung T1 and PY was found with a negative slope of -3.2 ms/year (95% confidence interval [CI] [-5.8, -0.6], p = 0.02), when adjusted for age and height. Lung T1 shortens with ageing among all subjects, -4.0 ms/year (95%CI [-6.3, -1.7], p = 0.001), and among the never smokers, -3.7 ms/year (95%CI [-6.0, -1.3], p = 0.003). Conclusions A correlation between lung T1 and PY when adjusted for both age and height was found, and T1 of the lung shortens with ageing. Accordingly, PY and age can be significant confounding factors when T1 is used as a biomarker in lung MRI studies that must be taken into account to detect underlying patterns of disease.

    Background. Cotrimoxazole preventive therapy (CPT) is recommended for all human immunodeficiency virus (HIV)–exposed infants to avoid opportunistic infections. Cotrimoxazole has antimalarial effects and appears to reduce clinical malaria infections, but the impact on asymptomatic malaria infections is unknown. Methods. We conducted an observational cohort study using data and dried blood spots (DBSs) from the Breastfeeding, Antiretrovirals and Nutrition study to evaluate the impact of CPT on malaria infection during peak malaria season in Lilongwe, Malawi. We compared malaria incidence 1 year before and after CPT implementation (292 and 682 CPT-unexposed and CPT-exposed infants, respectively), including only infants who remained HIV negative by 36 weeks of age. Malaria was defined as clinical, asymptomatic (using DBSs at 12, 24, and 36 weeks), or a composite outcome of clinical or asymptomatic. Linear and binomial regression with generalized estimating equations were used to estimate the association between CPT and malaria. Differences in characteristics of parasitemias and drug resistance polymorphisms by CPT status were also assessed in the asymptomatic infections. Results. CPT was associated with a 70% (95% confidence interval, 53%–81%) relative reduction in the risk of asymptomatic infection between 6 and 36 weeks of age. CPT appeared to provide temporary protection against clinical malaria and more sustained protection against asymptomatic infections, with no difference in parasitemia characteristics. Conclusions. CPT appears to reduce overall malaria infections, with more prolonged impacts on asymptomatic infections. Asymptomatic infections are potentially important reservoirs for malaria transmission. Therefore, CPT prophylaxis may have important individual and public health benefits. PMID:25900173

    Full Text Available Background & objectives: In malaria endemic areas, continuous exposure to Plasmodium parasites leads to asymptomatic carriers that provide a reservoir, contributing to the persistence of malaria transmission. Thus, a study of the degree of prevalence of asymptomatic parasitaemias will help in assessing the level of reservoir of infection. Methods: All the consented participants without any signs and symptoms, suggestive of malaria were interviewed and thick blood smears were made to detect malaria parasites. The children presenting with malaria or any other severe illness, and those declining to give consent were excluded from the study. Results: A total of 118 (59.6% children out of 198 apparently healthy children were positive for malaria parasites while 80 (40.4% children were negative for malaria parasites. Prevalence of asymptomatic malaria was higher in males 75 (63.6% compared to females 43 (36.4%, but the difference was not statistically significant. Incidence of asymptomatic malaria was highest with 76.1% in the children aged 6– 10 yr. There was statistically significant association of the use of bednet on prevalence of asymptomatic malaria. Interpretation & conclusion: High prevalence of asymptomatic malaria detected in this study is a big challenge and can be a threat to the present malaria control programme. Thus, it should be considered in assessing and reorganising more effective malaria elimination strategies to achieve the desired goal of malaria control.

    Full Text Available Stroke remains an exceedingly incident and prevalent public health burden across the globe, with an estimated 16 million new strokes per annum and prevalence over 60 million, and extracranial internal carotid artery atherosclerotic disease is an important risk factor for stroke. Randomized trials of surgical treatment were conducted (North American Symptomatic Carotid Endarterectomy Trial, European Carotid Surgery Trial and demonstrated efficacy of carotid endarterectomy for secondary prevention of stroke in patients with cerebrovascular events (e.g. ipsilateral stroke, transient ischemic attack, and/or amaurosis fugax attributable to a diseased artery with 50–99% stenosis. Therapeutic clarity, however, proved elusive with asymptomatic carotid artery disease. Asymptomatic Carotid Atherosclerosis Study (ACAS, Asymptomatic Carotid Surgery Trial, and Veterans Affairs Cooperative Study (VACS suggested only modest benefit from surgical intervention for primary stroke prevention and the best medical therapy at the time of these trials is not comparable to modern medical therapy. ACT-1, Asymptomatic Carotid Surgery Trial-2, Stent-Protected Angioplasty in asymptomatic Carotid artery stenosis versus Endarterectomy Trial-2, European Carotid Surgery Trial-2, Carotid Revascularization Endarterectomy Versus Stenting Trial-2 are trials that are recent, ongoing, or in development that include diverse populations across Europe and North America, complementary trial designs, and a collaborative spirit that should provide clinicians with evidence that informs best clinical practice for asymptomatic carotid artery disease.

    Malaria remains a major public health problem in the Democratic Republic of Congo (DRC) with 14 million cases reported by the WHO Malaria Report in 2014. Asymptomatic malaria cases are known to be prevalent in endemic areas and are generally untreated, resulting in a significant source of gametocytes that may serve as reservoir of disease transmission. Considering that microscopy certainly underestimates the prevalence of Plasmodium infections within asymptomatic carriers and that PCR assays are currently recognized as the most sensitive methods for Plasmodium identification, this study was conducted to weigh the asymptomatic carriage in DRC by a molecular method. Six provinces were randomly selected for blood collection in which 80 to 100 individuals were included in the study. Five hundred and eighty blood samples were collected and molecular diagnosis was performed. Globally, almost half of the samples collected from asymptomatic individuals (280/580; 48.2%) had Plasmodium infections and the most species identified was P. falciparum alone in combination with P. malariae. The high prevalence reported here should interpellate the bodies involved in malaria control in DR Congo to take into account asymptomatic carriers in actions taken and consider asymptomatic malaria as a major hurdle for malaria elimination.

    Introducción: La obesidad morbida es una enfermedad que debe ser tratada de forma integral (i.e., multi/ interdisciplinar). Para esta condicion la cirugia bariatrica es efectiva y segura en el tratamiento, sin embargo, a mayor peso preoperatorio podria aumentar la morbimortalidad. Objetivo: El objetivo del estudio es determinar los efectos de un programa de tratamiento interdisciplinar sobre parametros metabolicos, antropometricos y la condicion fisica en candidatos a cirugia bariatrica. Material y métodos: Un hombre y nueve mujeres con un promedio de 42,5 anos de edad con obesidad morbida (n = 3) u obesidad y comorbilidades (diabetes mellitus tipo II, hipertension arterial, dislipidemia, resistencia a la insulina) (n=7) candidatos a cirugia bariatrica, fueron sometidos a ejercicio fisico, apoyo psicologico y educacion nutricional, tres veces por semana durante tres meses. Antes y 72 horas despues de la ultima sesion de intervencion se evaluo (en ayuno ≥12 horas): masa corporal, porcentaje de masa grasa, IMC, perimetro de cintura, condicion fisica, glicemia, colesterol total, colesterol HDL, colesterol LDL y trigliceridos. Resultados: Posterior a la intervencion la masa corporal (p=0,004), el IMC (p=0,002), el porcentaje de masa grasa (p=0,047) y la condicion fisica (p=0,000) presentaron cambios significativos. Las demas variables dependientes no presentaron cambios significativos, aunque tendieron a disminuir. Conclusiones: Una intervencion integral de frecuencia moderada y corta duracion (i.e., tres sesiones/semana durante tres meses) permitiria reducir significativamente el peso y la grasa corporal, ademas de mejorar considerablemente la condicion fisica en candidatos a cirugia bariatrica. Una mayor duracion y/o frecuencia de intervencion podria ser necesaria para modificar significativamente variables plasmaticas.

    Full Text Available Context Nonalcoholic fatty liver disease encompasses a spectrum of histopathological changes that range from simple steatosis to nonalcoholic steatohepatitis. Works suggest that iron (Fe deposits in the liver are involved in the physiopathology of nonalcoholic steatohepatitis. Objective The aim of this study was to determine the prevalence of simple steatosis and nonalcoholic steatohepatitis in patients with morbid obesity, subjected to bariatric surgery and to establish a correlation of the anatomopathological findings with the presence of liver fibrosis. Methods A total of 250 liver biopsies were conducted in the transoperation of the surgeries. Results Steatosis was present in 226 (90.4% of the samples, 76 (30.4% being classified as mild; 71 (28.4% as moderate and 79 (31.6% as intense. Nonalcoholic steatohepatitis was diagnosed in 176 (70.4% cases, where 120 (48.4% were mild; 50 (20% were moderate, and 6 (2.4% cases were intense. Fibrosis was referred to in 108 (43.2% biopsies, 95 of which (38% were mild; 2 (0.8% were moderate; 7 (2.8% were intense, and cirrhosis was diagnosed in 4 (1.6% cases. There was a correlation between the degree of steatosis and the level of inflammatory activity (rs = 0.460; P<0.001 and between the degree of this activity and the degree of fibrosis (rs = 0.583; P<0.001. Only 13 (5.2% samples showed Fe deposits. Conclusion There is a high prevalence of nonalcoholic steatohepatitis in these patients and a positive correlation of the degrees of nonalcoholic steatohepatitis with the intensity of fibrosis. The low prevalence of Fe deposits found makes it questionable that the presence of this ion has any participation in the physiopathogeny of nonalcoholic fatty liver disease.

    Obesity is associated with respiratory symptoms that are reported to improve with weight loss, but this is poorly reflected in spirometry, and few studies have measured respiratory mechanics with oscillometry. We investigated whether early changes in lung mechanics following weight loss are detectable with oscillometry. Furthermore, we investigated whether the changes in lung mechanics measured in the supine position following weight loss are associated with changes in sleep quality. Nineteen severely obese female subjects (mean body mass index, 47.2 ± 6.6 kg/m(2)) were evaluated using spirometry, oscillometry, plethysmography, and the Pittsburgh Sleep Quality Index before and 5 weeks after bariatric surgery. These tests were conducted in both the upright and the supine position, and pre- and postbronchodilation with 200 μg of salbutamol. Five weeks after surgery, weight loss of 11.5 ± 2.5 kg was not associated with changes in spirometry and plethysmography, with the exception of functional residual capacity. There were also no changes in upright respiratory system resistance (Rrs) or reactance following weight loss. Importantly, however, in the supine position, weight loss caused a substantial reduction in Rrs. In addition, sleep quality improved significantly and was highly correlated with the reduction in supine Rrs. Prior to weight loss, subjects did not respond to the bronchodilator when assessed in the upright position with either spirometry or oscillometry; however, with modest weight loss, bronchodilator responsiveness returned to the normal range. Improvements in lung mechanics occur very early after weight loss, mostly in the supine position, resulting in improved sleep quality. These improvements are detectable with oscillometry but not with spirometry.

    This study examined healthcare utilization and associated costs for a severely obese population before receiving bariatric surgery relative to an age- and sex-matched sample from the Australian general population. Severely obese subjects receiving laparoscopic adjustable gastric banding (LAGB) surgery in 2009 (n = 11,769) were identified. Utilization of medical services and pharmaceuticals in the 3.5 years before surgery were ascertained for each severely obese subject through linkage with Medicare, Australia's universal health insurance scheme. Equivalent data were retrieved for each subject from the matched general population sample (n = 140,000). Severely obese subjects utilized significantly more medical services annually compared to the general population (mean: 22.8 vs. 12.1/person, standardized incidence ratio (SIR): 1.89 (95% confidence interval (CI) 1.88-1.89)), translating to twofold higher mean annual costs (Australian $1,140 vs. $567/person). The greatest excess costs in the obese related to consultations with general practitioners, psychiatrists/psychologists and other specialists, investigations for obstructive sleep apnea, and in vitro fertilization. Severely obese subjects also utilized significantly more pharmaceutical prescriptions annually (mean: 11.4 vs. 5.3/person, SIR 2.18 (95% CI: 2.17-2.19)), translating to 2.2-fold higher mean annual costs ($595/person vs. $270/person). The greatest excess costs in the obese related to diabetes drugs, lipid-modifying agents, psychoanaleptics, acid-related disorder drugs, agents acting on the rennin-angiotensin system, immunosuppressants, and obstructive airway disease drugs. Overall, healthcare costs in the severely obese population were more than double those incurred by the general population. PMID:22627914

    Full Text Available ABSTRACTOBJECTIVE: To examine whether there are changes in the distance between the orotracheal tube and carina induced by orthostatic retractor placement or by pneumoperitoneum insufflation in obese patients undergoing gastroplasty.METHODS: 60 patients undergoing bariatric surgery by two techniques: open (G1 or videolaparoscopic (G2 gastroplasty were studied. After tracheal intubation, adequate ventilation of both hemitoraxes was confirmed by lung auscultation. The distance orotracheal tube-carina was estimated with the use of a fiber bronchoscope before and after installation of orthostatic retractors in G1 or before and after insufflation of pneumoperitoneum in patients in G2.RESULTS: G1 was composed of 22 and G2 of 38 patients. No cases of endobronchial intubation were detected in either group. The mean orotracheal tube-carina distance variation was estimated in -0.03 cm (95% CI 0.06 to -0.13 in the group of patients undergoing open gastroplasty and in -0.42 cm (95% CI -0.56 to -1.4 in the group of patients undergoing videolaparoscopic gastroplasty. The extremes of variation in each group were: 0.5 cm to -1.6 cm in patients undergoing open surgery and 0.1 cm to -2.2 cm in patients undergoing videolaparoscopic surgery.CONCLUSIONS: There was no significant change in orotracheal tube-CA distance after placement of orthostatic retractors in patients undergoing open gastroplasty. There was a reduction in orotracheal tube-CA distance after insufflation of pneumoperitoneum in patients undergoing videolaparoscopic gastroplasty. We recommend attention to lung auscultation and to signals of ventilation monitoring and reevaluation of orotracheal tube placement after peritoneal insufflation.

    AIM: To investigate the prevalence of advanced polyps in asymptomatic Chinese and to determine the risk of proximal advanced colonic polyps in subjects with and without polyps in the distal colon.METHODS: Data were collected prospectively during colonoscopic examinations performed in 5 973 subjects as part of health evaluation at our unit from December 1997 to December 2003. Polyps were considered advanced, if they were larger than 10 mm or were tubovillous, villous or malignant. Proximal colon was defined as the splenic flexure and more proximal portions of the colon.RESULTS: Colon polyps were detected in 971 (16.3%)subjects (613 males and 358 females) with their mean age being 56.6±10.7 years. Advanced polyps were noted in 199 (3.3%) individuals. Subjects were sub-classified according to the location of polyps into three groups: distal (569, 58.6%), proximal (284, 29.2%), and combined proximal and distal (118, 12.2%) groups. Subjects with advanced polyps in these three groups were 95 (9.8%),56 (5.8%), and 48 (4.9%) respectively. In the 48 subjects with advanced combined polyps, 13 advanced polyps were distributed at the distal colon, 17 at the proximal colon,and 18 at both. Eighteen colon cancers including 12 at sigmoid and 6 at ascending colon were confirmed by final pathology. The relative risk for advanced proximal polyp according to distal findings was 3.1 (95%CI: 1.3-7.4) for hyperplastic polyp, 2.7 (95%CI: 1.4-5.3) for tubular polyp and 13.5 (95%CI: 5.1-35.4) for advanced polyp as compared to that for no polyp. However, 56 (28.2%) of 199 subjects with advanced polyps had no index polyps at the distal colon and might go undetected under sigmoidoscopic screening.CONCLUSION: Although distal lesions can predict the risk of advanced proximal polyps, a substantial portion of Chinese with advanced proximal polyps is not associated with any distal sentinel lesions. These data have implications for screening policy of colon cancers in Taiwanese Chinese.

    Full Text Available BACKGROUND: Cardiac biomarkers are often elevated in dialysis patients showing the presence of left ventricular dysfunction. The aim of the study is to establish the plasma levels of high-sensitivity cardiac troponin T (hs TnT, precursor of B-natriuretic peptide (NT-proBNP and high sensitivity C-reactive protein (hs CRP and their relation to the presence of left ventricular hypertrophy (LVH in patients undergoing hemodialysis without signs of acute coronary syndrome or heart failure. MATERIAL AND METHODS: Were studied 48 patients - 26 men and 22 women. Pre and postdialysis levels of hs cTnT, NT-proBNP and hs CRP were measured at week interim procedure. Patients were divided in two groups according to the presence of echocardiographic evidence of LVH - gr A - 40 patients (with LVH, and gr B - 8 patients (without LVH. RESULTS: In the whole group of patients was found elevated predialysis levels of all three biomarkers with significant increase (p < 0.05 after dialysis with low-flux dialyzers. Predialysis values of NT-proBNP show moderate positive correlation with hs cTnT (r = 0.47 and weaker with hs CRP (r = 0.163. Such dependence is observed in postdialysis values of these biomarkers. There is a strong positive correlation between the pre and postdialysis levels: for hs cTnT (r = 0.966, for NT-proBNP (r = 0.918 and for hs CRP (r = 0.859. It was found a significant difference in the mean values of hs cTnT in gr. A and gr. B (0.07 ± 0.01 versus 0.03 ± 0.01 ng /mL, p < 0.05 and NT-proBNP (15,605.8 ± 2,072.5 versus 2,745.5 ± 533.55 pg /mL, p < 0.05. Not find a significant difference in hs CRP in both groups. CONCLUSIONS: The results indicate the relationship of the studied cardiac biomarkers with LVH in asymptomatic patients undergoing hemodialysis treatment.

    Introduction Wound complications in post-bariatric patients undergoing body-contouring surgery after massive weight loss are not uncommon and often, surgical debridement or conservative management is necessary. Honey is one of the most ancient remedies for wound care and it is also considered to possess debriding effects. Current research has demonstrated promising results showing that honey can improve wound granulation and epithelialization, reduce exudate and shorten healing times. Methods This case report has been reported in line with the CARE criteria. Presentation of case A 40 year-old female suffered wound infection and dehiscence after undergoing post-bariatric abdominoplasty. The patient was not interested in surgical revision and split skin grafting. Therefore, conservative wound treatment with topical Manuka honey was instituted resulting in significant clinical improvement and effective healing concurrently with good patient satisfaction. Discussion Surgical wound complications in post-bariatric patients undergoing abdominoplasty are common and often require surgical revision or conservative wound treatment. No previous publication has addressed outpatient treatment of post-bariatric abdominoplasty wound complications with medical grade honey. Conclusion Although more research is needed for definitive conclusions of honey’s efficacy, it is safe and as presented in our case, it may under certain circumstances reduce the need of surgical wound debridement and serve as a remedy for conservative treatment.

    减重手术是治疗肥胖症最有效并可明显减重的治疗选择之一.与腹腔镜下可调节胃束带术相比,腹腔镜下Roux-en-Y胃旁路术具有更多的获益及手术风险.减重手术后可出现多种胃肠激素水平的变化,能部分解释减重手术后的体重下降及糖尿病缓解机制.减重手术后的治疗管理应是多学科综合治疗,包括调整饮食结构、增加身体活动量、纠正行为和药物治疗.%Bariatric surgery is one of the most effective treatment options for obesity. Compared with laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery has demonstrated more benefits and surgical risks. Bariatric surgery can result in the decreases in multiple gastrointestinal hormone levels, which can partially explain the mechanisms behind weight loss and resolution of diabetes after bariatric surgery. The management after bariatric surgery should be multidisciplinary and comprehensive, including dietary adjustment, physical exercise, behavioral intervention, and drug therapy.

    Objective. US primary care physicians are inadequately educated on how to provide obesity treatment. We sought to assess physician training in obesity and to characterize the perceptions, beliefs, knowledge, and treatment patterns of primary care physicians. Methods. We administered a cross-sectional web-based survey from July to October 2014 to adult primary care physicians in practices affiliated with the Massachusetts General Hospital (MGH). We evaluated survey respondent demographics, personal health habits, obesity training, knowledge of bariatric surgery care, perceptions, attitudes, and beliefs regarding the etiology of obesity and treatment strategies. Results. Younger primary care physicians (age 20-39) were more likely to have received some obesity training than those aged 40-49 (OR: 0.08, 95% CI: 0.008-0.822) or those 50+ (OR: 0.03, 95% CI: 0.004-0.321). Physicians who were young, had obesity, or received obesity education in medical school or postgraduate training were more likely to answer bariatric surgery knowledge questions correctly. Conclusions. There is a need for educational programs to improve physician knowledge and competency in treating patients with obesity. Obesity is a complex chronic disease, and it is important for clinicians to be equipped with the knowledge of the multiple treatment modalities that may be considered to help their patients achieve a healthy weight.

    2015-11-01

    Physical activity (PA) and sedentary behaviours (SB-i.e. activities involving low-energy expenditure and a sitting/reclining posture) may each have significant implications for weight loss and other bariatric surgery outcomes. While early studies suggested that patients typically comply with clinical recommendations to adopt habitual PA, these data were based on retrospective questionnaires. Conversely, recent studies incorporating mobile health (mHealth) technologies (e.g. objective monitors), which assess PA and SB in real time and in the natural environment, show that most patients are inactive and highly sedentary pre-operatively and only make modest changes in these behaviours postoperatively. In addition to using mHealth technologies for obtaining accurate and detailed information on PA and SB, they are increasingly being employed to intervene on patients' PA and SB and/or evaluate intervention outcomes. Researchers and clinicians are encouraged to consider the benefits of using mHealth technology when studying and treating PA and SB in bariatric surgery patients.

    Genomic studies and high-throughput experiments often produce large lists of candidate genes among which only a small fraction are truly relevant to the disease, phenotype or biological process of interest. Gene prioritization tackles this problem by ranking candidate genes by profiling candidates across multiple genomic data sources and integrating this heterogeneous information into a global ranking. We describe an extended version of our gene prioritization method, Endeavour, now available for six species and integrating 75 data sources. The performance (Area Under the Curve) of Endeavour on cross-validation benchmarks using 'gold standard' gene sets varies from 88% (for human phenotypes) to 95% (for worm gene function). In addition, we have also validated our approach using a time-stamped benchmark derived from the Human Phenotype Ontology, which provides a setting close to prospective validation. With this benchmark, using 3854 novel gene-phenotype associations, we observe a performance of 82%. Altogether, our results indicate that this extended version of Endeavour efficiently prioritizes candidate genes. The Endeavour web server is freely available at https://endeavour.esat.kuleuven.be/.

    2012-01-01

    This paper presents newly discovered candidate cave entrances into Martian near-surface lava tubes, volcano-tectonic fracture systems, and pit craters and describes their characteristics and exploration possibilities. These candidates are all collapse features that occur either intermittently along laterally continuous trench-like depressions or in the floors of sheer-walled atypical pit craters. As viewed from orbit, locations of most candidates are visibly consistent with known terrestrial features such as tube-fed lava flows, volcano-tectonic fractures, and pit craters, each of which forms by mechanisms that can produce caves. Although we cannot determine subsurface extents of the Martian features discussed here, some may continue unimpeded for many kilometers if terrestrial examples are indeed analogous. The features presented here were identified in images acquired by the Mars Odyssey's Thermal Emission Imaging System visible-wavelength camera, and by the Mars Reconnaissance Orbiter's Context Camera. Select candidates have since been targeted by the High-Resolution Imaging Science Experiment. Martian caves are promising potential sites for future human habitation and astrobiology investigations; understanding their characteristics is critical for long-term mission planning and for developing the necessary exploration technologies.

    2006-05-01

    The evolution of malaria in Brazil, its morbidity, the malaria control programs, and the new challenges for these programs in the light of the emergence of asymptomatic infection in the Amazon region of Brazil were reviewed. At least six Brazilian research groups have demonstrated that asymptomatic infection by Plasmodium is an important impediment to malaria control, among mineral prospectors in Mato Grosso and riverside communities in Rondônia and, in our group, in the middle and upper reaches of the Negro river, in the state of Amazonas. Likewise, other researchers have studied the problem among indigenous communities in the Colombian, Peruvian, and Venezuelan parts of the Amazon basin, adjacent to Brazil. The frequency of positive results from the polymerase chain reaction (PCR) among asymptomatic individuals has ranged from 20.4 to 49.5%, and the presence of Plasmodium in the thick blood smears, from 4.2 to 38.5%. Infection with Anopheles darlingi has also been demonstrated by xenodiagnosis among asymptomatic patients with positive PCR results. If a mean of 25% is taken for the asymptomatic infection caused by Plasmodium sp. in the Amazon region of Brazil, malaria control will be difficult to achieve in that region with the measures currently utilized for such control.

    Introduction. Asymptomatic malaria is prevalent in highly endemic areas of Africa and is new challenge for malaria prevention and control strategies. Objective. To determine the prevalence of asymptomatic malaria and associated risk factors among school children in Sanja Town, northwest Ethiopia. Methods. A cross-sectional study was conducted from February to March 2013, on 385 school children selected using stratified proportionate systematic sampling technique. Pretested questionnaire was used to collect sociodemographic data and associated risk factors. Giemsa-stained thin and thick blood films were examined for detection, identification, and quantification of malaria parasites. Data were entered and analyzed using SPSS 20.0 statistical software. Multivariate logistic regression was done for assessing associated risk factors and proportions for categorical variables were compared using chi-square test. P values less than 0.05 were taken as statistically significant. Results. The prevalence of asymptomatic malaria was 6.8% (n = 26). The majority of parasitemic study participants had low parasite density 65.5% (17/26). Level of grade, age, bed net usage, and frequent exposure to malaria infection were associated with risk of asymptomatic malaria. Conclusion. Asymptomatic malaria was low in this study area and is associated with level of grade, age, bed net usage, and frequent exposure to malaria infection. PMID:27355032

    To make normative width measurements of the ischiofemoral (IF) space in an asymptomatic population and to record soft tissue MRI signal variations within the IF space in order to determine whether such variations are associated with IF space dimensions. Normative width measurements of the IF space were prospectively made in 418 hips on 1.5 T MR images of 209 asymptomatic volunteers. Quantitative and qualitative assessments of the IF soft tissues including the quadratus femoris (QF) muscle were also made. The mean IF space width was 2.56 ± 0.75 cm (right, 2.60 ± 0.75 cm; left, 2.53 ± 0.75 cm). Soft tissue MRI signal abnormalities were present within the IF space in 19 (9.1 %) of 209 volunteers. Soft tissue abnormalities within the IF space included oedema (3/209, 1.4 %) of the QF and/or surrounding soft tissue, and only fatty infiltration (16/209, 7.7 %) of the QF. Bilateral IF spaces are asymmetrical in asymptomatic persons. There is ≥10 % of width difference between right and left IF spaces in approximately half of asymptomatic individuals. Fatty infiltration and oedema can be present at the IF space in a small portion of the asymptomatic population, who also have narrower IF spaces than those without soft tissue MRI signal abnormalities.

    To identify asymptomatic patients is the challenging task and the essential first step in diagnosis. Findings of dental panoramic radiographs include not only dental conditions but also radiographic signs that are suggestive of possible systemic diseases such as osteoporosis, arteriosclerosis, and maxillary sinusitis. Detection of such signs on panoramic radiographs has a potential to provide supplemental benefits for patients. However, it is not easy for general dental practitioners to pay careful attention to such signs. We addressed the development of a computer-aided detection (CAD) system that detects radiographic signs of pathology on panoramic images, and the design of the framework of new screening pathway by cooperation of dentists and our CAD system. The performance evaluation of our CAD system showed the sensitivity and specificity in the identification of osteoporotic patients were 92.6 % and 100 %, respectively, and those of the maxillary sinus abnormality were 89.6 % and 73.6 %, respectively. The detection rate of carotid artery calcifications that suggests the need for further medical evaluation was approximately 93.6 % with 4.4 false-positives per image. To validate the utility of the new screening pathway, preliminary clinical trials by using our CAD system were conducted. To date, 223 panoramic images were processed and 4 asymptomatic patients with suspected osteoporosis, 7 asymptomatic patients with suspected calcifications, and 40 asymptomatic patients with suspected maxillary sinusitis were detected in our initial trial. It was suggested that our new screening pathway could be useful to identify asymptomatic patients with systemic diseases.

    Temporal cortex abnormalities are common in patients with mesial temporal lobe epilepsy due to hippocampal sclerosis (MTLE+HS) and believed to be relevant to the underlying mechanisms. In the present study, we set out to determine the familiarity of temporal cortex morphologic alterations in a cohort of MTLE+HS patients and their asymptomatic siblings. A surface-based morphometry (SBM) method was applied to process MRI data acquired from 140 individuals (50 patients with unilateral MTLE+HS, 50 asymptomatic siblings of patients, and 40 healthy controls). Using a region-of-interest approach, alterations in temporal cortex morphology were determined in patients and their asymptomatic siblings by comparing with the controls. Alterations in temporal cortex morphology were identified in MTLE+HS patients ipsilaterally within the anterio-medial regions, including the entorhinal cortex, parahippocampal gyrus, and temporal pole. Subtle but similar pattern of morphology changes with a medium effect size were also noted in the asymptomatic siblings. These localized alterations were related to volume loss that appeared driven by shared contractions in cerebral cortex surface area. These findings indicate that temporal cortex morphologic alterations are common to patients and their asymptomatic siblings and suggest that such localized traits are possibly heritable.

We compared the prevalence of MRI-identified wrist abnormalities and wrist ROM between asymptomatic and symptomatic computer users. Methods MR images at 1.5 T of both wrists were obtained from 10 asymptomatic controls (8 F, 2 M and 14 computer users (10 F, 4 M with chronic wrist pain (10 bilateral; 4 right-side. Maximum wrist range of motion in flexion and radioulnar deviation was measured with an electrogoniometer. Results Extraosseous ganglia were identified in 66.6% of asymptomatic wrists and in 75% of symptomatic wrists. Intraosseous ganglia were identified in 45.8% of asymptomatic wrists and in 75% of symptomatic wrists, and were significantly (p p Conclusions This appears to be the first MRI study of wrist abnormalities in computer users. This study demonstrates that a variety of wrist abnormalities are common in computer users and that only intraosseous ganglia prevalence and size differed between asymptomatic and symptomatic wrists. Flexion was restricted in the dominant wrist of the symptomatic group, but the correlation between wrist flexion and intraosseous ganglion burden did not reach significance. Flexion restriction may be an indicator of increased joint loading, and identifying the cause may help to guide preventive and therapeutic interventions.

    Full Text Available Dengue virus infection is a common tropical disease which often occurs without being detected. These asymptomatic cases provide information in relation to the manifestation of immunological aspects. In this study, we developed an ELISA method to compare neutralizing effects of dengue prM and E antibodies between dengue patients and their asymptomatic household members. Recombinant D2 premembrane (prM was constructed, cloned, and tested for antigenicity. The recombinant protein was purified and tested with controls by using an indirect ELISA method. Positive dengue serum samples with their asymptomatic pair were then carried out onto the developed ELISA. In addition, commercially available recombinant envelope (E protein was used to develop an ELISA which was tested with the same set of serum samples in the prM ELISA. Asymptomatic individuals showed preexisting heterotypic neutralizing antibodies. The recombinant prM was antigenically reactive in the developed ELISA. Dengue patients had higher prM and E antibodies compared to their household members. Our study highlights the neutralizing antibodies levels with respect to dengue prM and E between dengue patients and asymptomatic individuals.

    Full Text Available Abstract Background Given that bariatric surgery (BS and lifestyle intervention (LI represent two vastly different approaches to treating severe obesity, there is growing interest in whether individuals who seek BS versus LI also differ on weight-related behaviors. In the present study, we compared BS- and LI-seekers on physical activity (PA and sedentary behaviors (SB, and examined between-group differences in health-related quality of life (HRQoL, while controlling for PA. Findings A sample of 34 LI-seekers were matched with 34 BS-seekers on gender, age, BMI, and PA monitor-daily wear time (age: 42.1±10.0 years; BMI: 45.6±6.5 kg/m2. PA and SB were assessed over a 7-day period via the SenseWear Armband (SWA. HRQoL was measured using the SF-36, with scores standardized to a population normal distribution (M=50, SD=10. Participants wore the SWA for 13.7±1.6 h/day.

BS-seeker group status was related to lower physical functioning (β=0.30, p=0.009, independent of gender, age, BMI, and daily PA. Conclusions Findings suggest that seeking BS versus LI is not related to patterns of PA or SB, and that lower subjective physical functioning is not associated with lower overall PA levels in BS-seekers.

    Reports of combined candidal and herpetic esophagitis in immunocompetent states are rare and sporadic. A 44-year-old previously healthy lady presented with a one week history of progressive dysphagia, odynophagia and fever. Esophagogastroduodenoscopy (EGD) showed extensive desquamation of the entire esophagus except for distal 4 cm. Histopathological examination revealed ulcerated and inflamed squamous epithelium with the margin of ulcer showing a few overhanging squamous cells with dense eosinophilic cytoplasm, multinucleated and faceted nuclei with glassy chromatin, and an occasional Cowdry type A intranuclear inclusion bodies. Few candidal spores were seen in the underlying stroma. Intravenous acyclovir, fluconazole and pantoprazole were initiated. Oral analgesics were given for pain relief. She was treated for a total of 14 days. She showed significant improvement and was tolerating oral intake after discharge. The patient was asymptomatic with no evidence of recurrence at a 2-month follow-up.

    @@ Paget's disease of bone is a deforming bone disease (osteitis deformans) characterized by increased bone remodeling,bone hypertrophy,and abnormal bone structure,leading to bone expansion,deformities,easy fractures,and occasionally,neoplastic transformation.It is the second most common bone disorder after osteoporosis.1 The disease is relatively rare in Asia but is common in Europe and North America,affecting approximately 2% of the population over 50 years,although lately,a decline in the prevalence has been reported.2 Paget's disease commonly affects people in or past their middle age and is slightly more common in men than in women.1 The exact cause of Paget's disease is not known.Environmental agents,particularly paramyxoviral infections (measles and canine distemper viruses) have been postulated as potential etiological factors.3 Recently,a strong genetic component has been described,with candidate loci suggested at 18q,5q35-QTER,and particularly,the squestosome 1/p62.2,3 The pathological process in Paget's disease consists of one or more areas of aggressive and relentless osteoclastic activity,coupled with deposition of structurally abnormal excessive bone and matrix tissues.1,4 Most of the cases involve only one (monostotic) or few bones,particularly skull,vertebrae,pelvis,femur,and tibia.

  16. A reservoir of drug-resistant pathogenic bacteria in asymptomatic hosts.

    Gabriel G Perron

    Full Text Available The population genetics of pathogenic bacteria has been intensively studied in order to understand the spread of disease and the evolution of virulence and drug resistance. However, much less attention has been paid to bacterial carriage populations, which inhabit hosts without producing disease. Since new virulent strains that cause disease can be recruited from the carriage population of bacteria, our understanding of infectious disease is seriously incomplete without knowledge on the population structure of pathogenic bacteria living in an asymptomatic host. We report the first extensive survey of the abundance and diversity of a human pathogen in asymptomatic animal hosts. We have found that asymptomatic swine from livestock productions frequently carry populations of Salmonella enterica with a broad range of drug-resistant strains and genetic diversity greatly exceeding that previously described. This study shows how agricultural practice and human intervention may lead and influence the evolution of a hidden reservoir of pathogens, with important implications for human health.

    Full Text Available Sub-Saharan Africa records each year about thirty-two million pregnant women living in areas of high transmission of Plasmodium falciparum causing malaria. The aim of this study was to carve out the prevalence of asymptomatic malaria among pregnant women and to emphasize its influence on haematological markers. The prevalence of Plasmodium falciparum asymptomatic infection among pregnant women was 30% and 24% with rapid detection test (RDT and microscopy, respectively. The prevalence of P. falciparum asymptomatic malaria was reduced among pregnant women using sulfadoxine-pyrimethamine's intermittent preventive treatment and 61% of them were anaemic. Anaemia was significantly more common in women infected with P. falciparum compared with the uninfected pregnant women. Most of the women had normal levels of homocysteine and low levels of folate, respectively. Therefore, the systematic diagnosis of malaria should be introduced to pregnant women as a part of the antenatal care.

    Trichomoniasis may be asymptomatic or symptomatic in both sexes. The outcome of infection depends on the virulence factors of T. vaginalis, but these factors remain unclear. Genetic variability of the isolates and the host's immune response are likely to be key factors in that respect. Symptomatic and asymptomatic males infected with T. vaginalis were compared regarding the differences in antibody subclasses response in the urethral samples. In symptomatic cases there was a significant elevation in IgM, IgG1 & IgG2b levels in urethral samples, and a little, non-significant rise in IgG2a levels. However, there were no statistically significant differences between levels of IgA, IgG3 & IgG4. The results showed that specific IgG1 & IgM and to a lesser extent IgG2 may be involved in established symptomatic trichomoniasis in men, compared to asymptomatic ones. PMID:18383797

    The enthalpic and entropic contributions to the binding affinity of drug candidates have been acknowledged to be important determinants of the quality of a drug molecule. These quantities, usually summarized in the thermodynamic signature, provide a rapid assessment of the forces that drive the binding of a ligand. Having access to the thermodynamic signature in the early stages of the drug discovery process will provide critical information towards the selection of the best drug candidates for development. In this paper, the Enthalpy Screen technique is presented. The enthalpy screen allows fast and accurate determination of the binding enthalpy for hundreds of ligands. As such, it appears to be ideally suited to aid in the ranking of the hundreds of hits that are usually identified after standard high throughput screening.

    Leishmania is a protozoan parasite and a causative agent of the various clinical forms of leishmaniasis. High cost, resistance and toxic side effects of traditional drugs entail identification and development of therapeutic alternatives. The sound understanding of parasite biology is key for identifying novel drug targets, that can induce the cell mediated immunity (mainly CD4+ and CD8+ IFN-gamma mediated responses) polarized towards a Th1 response. These aspects are important in designing a new vaccine along with the consideration of the candidates with respect to their ability to raise memory response in order to improve the vaccine performance. This review is an effort to identify molecules according to their homology with the host and their ability to be used as potent vaccine candidates.

    Full Text Available Background: Malaria infestation during pregnancy is mostly asymptomatic and untreated especially in unbooked pregnancies. It presents with almost all the fetal complications of overt malaria in pregnancy. The aim of this study was to determine the effect of asymptomatic malaria parasitaemia on the neonates of unbooked parturients delivered at term at the Federal Teaching Hospital, Abakaliki. Materials and Methods: This study was conducted in the labour ward complex of the Federal Teaching Hospital, Abakaliki from March to May 2012. Unbooked pregnant women who fulfilled the inclusion criteria and gave consent were consecutively recruited. Cord blood and placenta tissue were collected for haemoglobin concentration determination and histology, respectively. Birth weights were determined with an electronic weighing machine. Statistical Analysis was done with 2008 Epi Info™ software and level of significant was set at P-value <0.05. Results: A total of 250 unbooked parturients were recruited, of which 194 (77.6% had asymptomatic malaria parasitaemia while 227 (90.8% had placental parasitisation. The prevalence of low birth weight in the study was 16.4%. There was significant relationship between asymptomatic malaria parasitemia and birth weight (X [2] = 43.70, P-value < 0.001. There were no low-birth-weight deliveries among paturients without placental parasitemia. No neonate, however, had anaemia in the study. Conclusion: Asymptomatic malaria parasitemia and placental parasitisation by malaria parasites contribute to the outcome of the foetal birth weight. Asymptomatic malaria parasitaemia and placental parasitaemia did not result in a corresponding foetal anaemia on babies delivered.

    Background Pulmonary tuberculosis (PTB) among asymptomatic Chinese patients with HIV infection has not been investigated despite high tuberculosis burden in China. This study was aimed to evaluate the prevalence, risk factors and clinical outcomes of PTB among asymptomatic patients with HIV/AIDS in Guangxi to facilitate the development of diagnostic and treatment strategies.Methods All asymptomatic adult HIV-infected patients with CD4 <350 cells/μl who attended four HIV clinics in Guangxi between August 2006 and March 2008 were evaluated for active PTB with physical examination, chest X-ray (CXR),sputum smear and/or sputum liquid culture. Data were described using median (interquartile range, IQR) and frequencies.Univariate and multivariate Logistic regression analyses were performed to identify risk factors associated with PTB.Results Among 340 asymptomatic subjects, 15 (4%) were diagnosed with PTB, with 4 (27%) sputum smear positive and 8 (53%) sputum culture positive. CXR has higher diagnostic sensitivity (87%) than sputum smear (25%) and sputum culture (67%), but lower specificity (56%) compared with sputum smear (99%) and culture (100%). In univariate analysis,injection drug user, body mass index (BMI) <18 kg/m2, CD4 <50 cells/μl and presence of peripheral lymphadenopathy were associated with an increased risk of asymptomatic PTB, while in multivariate analysis only peripheral lymphadenopathy maintained statistical significance (OR=7.6, 95% CI 1.4-40). Patients with negative smear and minor or no abnormalities on CXR had longer interval between screening and TB treatment.Conclusions PTB was relatively common in this group of HIV+ asymptomatic Chinese patients. Diagnosis is challenging especially where sputum culture is unavailable. These findings suggest that an enhanced evaluation for PTB needs to be integrated with HIV care in China and transmission prevention in China to control at both households and health care facilities, especially for patients

    Full Text Available Abstract Background Extreme obesity affects nearly 8% of Canadians, and is debilitating, costly and ultimately lethal. Bariatric surgery is currently the most effective treatment available; is associated with reductions in morbidity/mortality, improvements in quality of life; and appears cost-effective. However, current demand for surgery in Canada outstrips capacity by at least 1000-fold, causing exponential increases in already protracted, multi-year wait-times. The objectives and hypotheses of this study were as follows: 1. To serially assess the clinical, economic and humanistic outcomes in patients wait-listed for bariatric care over a 2-year period. We hypothesize deterioration in these outcomes over time; 2. To determine the clinical effectiveness and changes in quality of life associated with modern bariatric procedures compared with medically treated and wait-listed controls over 2 years. We hypothesize that surgery will markedly reduce weight, decrease the need for unplanned medical care, and increase quality of life; 3. To conduct a 3-year (1 year retrospective and 2 year prospective economic assessment of bariatric surgery compared to medical and wait-listed controls from the societal, public payor, and health-care payor perspectives. We hypothesize that lower indirect, out of pocket and productivity costs will offset increased direct health-care costs resulting in lower total costs for bariatric surgery. Methods/design Population-based prospective cohort study of 500 consecutive, consenting adults, including 150 surgically treated patients, 200 medically treated patients and 150 wait-listed patients. Subjects will be enrolled from the Edmonton Weight Wise Regional Obesity Program (Edmonton, Alberta, Canada, with prospective bi-annual follow-up for 2 years. Mixed methods data collection, linking primary data to provincial administrative databases will be employed. Major outcomes include generic, obesity-specific and preference

    Full Text Available Abstract Background Increased investment and commitment to malaria prevention and treatment strategies across Africa has produced impressive reductions in the incidence of this disease. Nevertheless, it is clear that further interventions will be necessary to meet the international target of a reversal in the incidence of malaria by 2015. This article discusses the prospective role of an innovative malaria control strategy - the community-based treatment of asymptomatic carriers of Plasmodium falciparum, with artemisinin-based combination therapy (ACT. The potential of this intervention was considered by key scientists in the field at an Advisory Board meeting held in Basel, in April 2009. This article summarizes the discussions that took place among the participants. Presentation of the hypothesis Asymptomatic carriers do not seek treatment for their infection and, therefore, constitute a reservoir of parasites and thus a real public-health risk. The systematic identification and treatment of individuals with asymptomatic P. falciparum as part of a surveillance intervention strategy should reduce the parasite reservoir, and if this pool is greatly reduced, it will impact disease transmission. Testing the hypothesis This article considers the populations that could benefit from such a strategy and examines the ethical issues associated with the treatment of apparently healthy individuals, who represent a neglected public health risk. The potential for the treatment of asymptomatic carriers to impair the development of protective immunity, resulting in a 'rebound' and age escalation of malaria incidence, is also discussed. For policymakers to consider the treatment of asymptomatic carriers with ACT as a new tool in their malaria control programmes, it will be important to demonstrate that such a strategy can produce significant benefits, without having a negative impact on the efficacy of ACT and the health of the target population.

    Full Text Available Renal stones are a common affliction presenting in an acute setting. We report a case of asymptomatic renal stone in an elderly gentleman presenting initially as a discharging lumbar sinus managed by subcapsular nephrectomy and radical excision of the fistula tract. Nephrocutaneous fistula is most commonly associated with tuberculosis, xanthogranulomatous pyelonephritis, and rarely with complicated calyceal stones, and its occurrence with asymptomatic pelvic stones is rare. We present the points in favor of radical open surgery in the management of such patients.

    Benign prostatic hyperplasia (BPH) is a disease of unknown etiology that significantly affects the quality of life in aging men. Histologic BPH may present itself either as symptomatic or asymptomatic in nature. To elucidate the molecular differences underlying BPH, gene expression profiles from the prostate transition zone tissue have been analyzed by using microarrays. A set of 511 differentially expressed genes distinguished symptomatic and asymptomatic BPH. This genetic signature separates BPH from normal tissue but does not seem to change with age. These data could provide novel approaches for alleviating symptoms and hyperplasia in BPH.

    Background: Surgery has been the method most widely used to manage the extraction of gastric bands with inclusion as a late complication of bariatric surgery; however, surgical extraction entails morbidity and limits future surgical procedures. The development of endoscopic techniques has provided an important means of improving the treatment of this complication, enabling minimally invasive and safe procedures that have a high success rate. Methods: A retrospective analysis was conducted of patients who had laparoscopic gastric banding complicated by intragastric migration and were treated endoscopically. A technique already described for managing this complication was employed. An MTW Endoskopie Dormia basket for mechanical lithotripsy or a standard 0.0035-in guidewire was placed around the band, and an MTW Endoskopie emergency lithotripter was used to section it, after which the band was extracted with a standard polypectomy snare. Also analyzed were the initial symptoms of patients with this complication, the mean time from surgery to development of the event, the success rate of endoscopic treatment, and complications, Results: A total of 127 patients had undergone gastric banding surgery in our Bariatric Surgery Center; of these, 12 patients (9.4 %) developed a complication such as intragastric migration of the band. Weight gain and pain were the main symptoms in 11 patients (92 %), and the mean time to the development of symptoms was 51.3 months. A single endoscopic treatment was successful in 7 of 9 patients (78 %). Only 1 complication, involving ventilation during anesthesia, occurred; no other adverse events were recorded. Conclusions: The endoscopic extraction of bands with inclusion is feasible and can be performed easily and successfully. The procedure is available in all hospitals and has a low incidence of related complications, so that unnecessary surgical procedures can be avoided.

    Roux-en Y gastric bypass is a highly effective bariatric/metabolic surgical procedure that can induce robust weight loss and even remission of type 2 diabetes. One of the characteristic consequences of Roux-en Y gastric bypass is the expedited nutrient delivery to the distal small intestine, where L-cells are abundant and bile acid reabsorption occurs. To examine the role of the distal small intestine in isolation from other components of Roux-en Y gastric bypass, the ileal transposition (IT) surgery has been used in various rat models. IT relocates the distal ileal segment to the upper jejunum distal to the ligament of Treitz without any other alterations in the gastrointestinal anatomy. Therefore, IT exposes the distal ileal tissue to ingested nutrients after a meal faster than the normal condition. Although there is some inconsistency in the effect of IT according to different types of rat models and different types of surgical protocols, IT typically improved glucose tolerance, increased insulin sensitivity and induced weight loss, and the findings were more prominent in obese diabetic rats. Suggested mechanisms for the metabolic improvements after IT include increased L-cell secretion (e.g., glucagon-like peptides and peptide YY), altered bile acid metabolism, altered host-microbial interaction, attenuated metabolic endotoxemia and many others. Based on the effect of IT, we can conclude that the contribution of the distal small intestine to the metabolic benefits of bariatric/metabolic surgery is quite considerable. By unveiling the mechanism of action of IT, we might revolutionize the treatment for obesity and type 2 diabetes.

    In several studies reduced striatal dopamine D2/3 receptor (D2/3R) availability was reported in obese subjects compared to lean controls. Whether this is a reversible phenomenon remained uncertain. We previously determined the short-term effect of Roux-en-Y gastric bypass surgery (RYGB) on striatal D2/3R availability (using [(123)I]IBZM SPECT) in 20 morbidly obese women. Striatal D2/3R availability was lower compared to controls at baseline, and remained unaltered after 6 weeks, despite significant weight loss. To determine whether long-term bariatric surgery-induced weight loss normalizes striatal D2/3R binding, we repeated striatal D2/3R binding measurements at least 2 years after RYGB in 14 subjects of the original cohort. In addition, we assessed long-term changes in body composition, eating behavior and fasting plasma levels of leptin, ghrelin, insulin and glucose. Mean body mass index declined from 46±7kg/m(2) to 32±6kg/m(2), which was accompanied by a significant increase in striatal D2/3R availability (p=0.031). Striatal D2/3R availability remained significantly reduced compared to the age-matched controls (BMI 22±2kg/m(2); p=0.01). Changes in striatal D2/3R availability did not correlate with changes in body weight/fat, insulin sensitivity, ghrelin or leptin levels. Scores on eating behavior questionnaires improved and changes in the General Food Craving Questionnaire-State showed a borderline significant correlation with changes in striatal D2/3R availability. These findings show that striatal D2/3R availability increases after long-term bariatric-surgery induced weight loss, suggesting that reduced D2/3R availability in obesity is a reversible phenomenon.
