Lapband Versus SAGB for Morbid Obesity. Long-Term Results of a Prospective Randomized Trial

Background: Gastric banding is currently one of the most performed procedures for morbid obesity. Results are related in part to the surgical technique and the quality of follow-up. Several bands are currently on the market, and it may bethat the type of band also plays a role in long-term results. The aim of this prospective randomized study was to compare the long-term results of the Lapband and the SAGB.Patients and methods: In three institutions with a common bariatric surgeon, consecutive patients undergoing laparoscopic gastric banding for morbid obesity were randomized to receive either a Lapband or a SAGB. The Lapband was placed using the perigastric and the SAGB with the pars flaccida technique. All data were collected prospectively. The median duration of follow-up was 131 months (103-147). Patients who lost their band were excluded from analysis as of band removal.Results: 180 patients were included between December 1998 and June 2002, 90 in each group. Except for age, which was lower in SAGB patients, the pre-operative characteristics were similar in the two patient groups. Early band-related morbidity was higher in the SAGB group (6,6 vs 0 %, p=0,03). Patients with a Lapband lost weight quicker than those with SAGB (EBMIL 50,8 vs 39,8 after 12 months, p<0,001), but the two weight loss curves joined after 24 months, and no difference could be observed later on up to 12 years after surgery (EBMIL 53,7 vs 58,1 % after 10 years, P=0,68). Long-term complications developed in 91 patients (50,5 %). Severe complications leading to band removal±conversion to another procedure developed in 30 and 40 patients in the Lapband and SAGB group respectively (33,3 vs 44,4 %, p=0,16).Conclusions: This prospective randomized study shows no significant difference in the long-term results of gastric banding between the Lapband and the SAGB. Both bands were associated with significant long-term complication and band removal/conversion rates. Patients who retain their band have acceptable long-term weight loss. It is likely that the concept of gastric banding rather than the device itself plays the most important role in longterm results.

Growing up with bilateral hippocampal atrophy: from childhood to teenage.

The respective roles of the medial temporal lobe (MTL) structures in memory are controversial. Some authors put forward a modular account according to which episodic memory and recollection-based processes are crucially dependent on the hippocampal formation whereas semantic acquisition and familiarity-based processes rely on the adjacent parahippocampal gyri. Others defend a unitary view. We report the case of VJ, a boy with developmental amnesia of most likely perinatal onset diagnosed at the age of 8. Magnetic resonance imaging (MRI), including quantitative volumetric measurements of the hippocampal formation and of the entorhinal, perirhinal, and temporopolar cortices, showed severe, bilateral atrophy of the hippocampal formation, fornix and mammillary bodies; by contrast, the perirhinal cortex was within normal range and the entorhinal and temporopolar cortex remained within two standard deviations (SDs) from controls' mean. We examined the development of his semantic knowledge from childhood to teenage as well as his recognition and cued recall memory abilities. On tasks tapping semantic memory, VJ increased his raw scores across years at the same rate as children from large standardisation samples, except for one task; he achieved average performance, consistent with his socio-educational background. He performed within normal range on 74% of recognition tests and achieved average to above average scores on 42% of them despite very severe impairment on 82% of episodic recall tasks. Both faces and landscapes-scenes gave rise to above average scores when tested with coloured stimuli. Cued recall, although impaired, was largely superior to free recall. This case supports a modular account of the MTL with episodic, but not semantic memory depending on the hippocampal formation. Furthermore, the overall pattern of findings is consistent with evidence from both brain-damaged and neuroimaging studies indicating that recollection requires intact hippocampal formation and familiarity relies, at least partly, on the adjacent temporal lobe cortex.

Mitochondrial tRNA(Leu(UUR)) mutation m.3302A > G presenting as childhood-onset severe myopathy: threshold determination through segregation study.

Mitochondrial tRNA(Leu(UUR)) mutation m.3302A > G is associated with respiratory chain complex I deficiency and has been described as a rare cause of mostly adult-onset slowly progressive myopathy. Five families with 11 patients have been described so far; 5 of them died young due to cardiorespiratory failure. Here, we report on a segregation study in a family with an index patient who already presented at the age of 18 months with proximal muscular hypotonia, abnormal fatigability, and lactic acidosis. This early-onset myopathy was rapidly progressive. At 8 years, the patient is wheel-chair bound, requires nocturnal assisted ventilation, and suffers from recurrent respiratory infections. Severe complex I deficiency and nearly homoplasmy for m.3302A > G were found in muscle. We collected blood, hair, buccal swabs and muscle biopsies from asymptomatic adults in this pedigree and determined heteroplasmy levels in these tissues as well as OXPHOS activities in muscle. All participating asymptomatic adults had normal OXPHOS activities. In contrast to earlier reports, we found surprisingly little variation of heteroplasmy levels in different tissues of the same individual. Up to 45% mutation load in muscle and up to 38% mutation load in other tissues were found in non-affected adults. The phenotypic spectrum of tRNA(Leu(UUR)) m.3302A > G mutation seems to be wider than previously described. A threshold of more than 45% heteroplasmy in muscle seems to be necessary to alter complex I activity leading to clinical manifestation. The presented data may be helpful for prognostic considerations and counseling in affected families.

Parent-child agreement and prevalence estimates of diagnoses in childhood: direct interview versus family history method.

Diagnostic information on children is typically elicited from both children and their parents. The aims of the present paper were to: (1) compare prevalence estimates according to maternal reports, paternal reports and direct interviews of children [major depressive disorder (MDD), anxiety and attention-deficit and disruptive behavioural disorders]; (2) assess mother-child, father-child and inter-parental agreement for these disorders; (3) determine the association between several child, parent and familial characteristics and the degree of diagnostic agreement or the likelihood of parental reporting; (4) determine the predictive validity of diagnostic information provided by parents and children. Analyses were based on 235 mother-offspring, 189 father-offspring and 128 mother-father pairs. Diagnostic assessment included the Kiddie-schedule for Affective Disorders and Schizophrenia (K-SADS) (offspring) and the Diagnostic Interview for Genetic Studies (DIGS) (parents and offspring at follow-up) interviews. Parental reports were collected using the Family History - Research Diagnostic Criteria (FH-RDC). Analyses revealed: (1) prevalence estimates for internalizing disorders were generally lower according to parental information than according to the K-SADS; (2) mother-child and father-child agreement was poor and within similar ranges; (3) parents with a history of MDD or attention deficit hyperactivity disorder (ADHD) reported these disorders in their children more frequently; (4) in a sub-sample followed-up into adulthood, diagnoses of MDD, separation anxiety and conduct disorder at baseline concurred with the corresponding lifetime diagnosis at age 19 according to the child rather than according to the parents. In conclusion, our findings support large discrepancies of diagnostic information provided by parents and children with generally lower reporting of internalizing disorders by parents, and differential reporting of depression and ADHD by parental disease status. Follow-up data also supports the validity of information provided by adolescent offspring.

No Role for Cerebrospinal Fluid Myelin Basic Protein Levels in Patients Treated for Childhood Acute Lymphoblastic Leukemia.

INTRODUCTION: Central nervous system prophylaxis of childhood acute lymphoblastic leukemia has dropped rates of relapses but has been associated with neurotoxicity and imaging abnormalities. Predictors of neurotoxicity are lacking, because of inconsistency between clinical symptoms and imaging. Some have suggested that cerebrospinal fluid myelin basic protein (MBP) levels to be of potential interest. A retrospective analysis of MBP levels in correlation with clinical and radiologic data is presented. MATERIALS AND METHODS: MBP levels obtained at the time of intrathecals, charts, and neuroradiology reports were retrospectively analyzed. Academic achievement data were obtained from phone contacts with patients and families. RESULTS: We retrieved 1248 dosages of MBP in 83 patients, 381 neurologic examinations in 34 patients and 69 neuroradiologic investigations in 27 patients. Fifty-two patients had abnormal MBP levels. Radiologic anomalies were present in 47% of those investigated, 14% of them having school difficulties. Proportions of patients with school difficulties in the groups with abnormal MBP levels but no radiologic anomalies or with no radiologic investigations were 0% and 3%, respectively, which was lower than in the group of patients with normal MBP levels (100%, 22%, and 5%, respectively). DISCUSSION: Notwithstanding the retrospective character of our study, we conclude that there is limited usefulness of systematic dosage of MBP as indicator of treatment-induced neurotoxicity in acute lymphoblastic leukemia patients.

Opportunity to shape the prevention and management of obesity

Cooperation and Working Together (CAWT), the cross border health and social care partnership has been working with the Departments of Health to progress a three year cross border obesity prevention and management project aimed at families. They have been successful in securing funding from the EU INTERREG IVA programme. A planning workshop focussing on this will be held on Friday 26 June 2009.

Obesity Weighting up the Evidence: All-Island Multisectoral Conference on Obesity

The World Health Organization reports that overweight and obesity have reached epidemic proportions globally and estimates that approximately 1.6 billion adults and at least 20 million children under the age of five are overweight or obese. It is accepted that being overweight or obese increases the risk of health conditions such as heart disease, stroke, diabetes and some cancers and has significant impacts on a wide range of other factors including education, employment and emotional wellbeing. This conference aimed to present a multisectoral audience with the latest developments in overweight and obesity prevention and management. This presentation was given by Dr. Kevin Balanda, Institute of Public Health in Ireland. The Institute of Public Health in Ireland (IPH) is leading the development of an All-Ireland obesity observatory The obesity observatory development is being undertaken in collaboration with: - HRB Centre for Health and Diet Research ﾖ UCC /UCD - Centre of Excellence for Public Health (NI) - QUB Projected outcomes: Adequate sample size Data to be sought and recorded Usefulness of a database in influencing policy Value to clinicians in management of obesity

IPH response to DHSSPS obesity prevention framework consultation 'A Fitter Future for All'

Preventing obesity is a key priority for the Department of Health, Social Services and Public Safety (DHSSPS) in Northern Ireland. In support of this, the DHSSPS has led the development of a cross-Departmental, crosssectoral Obesity Prevention Framework for Northern Ireland 2011-2021, entitled A Fitter Future For All, which seeks to reduce the prevalence of overweight and obesity throughout  Northern Ireland. The Framework focuses action on three main pillars: food & nutrition; physical activity; and data and research, and within the context of three life course stages: Early Years; Children and Young People; and Adults. This approach is consistent with the responses being undertaken by a number of countries, following the Foresight Report.

Obesity markers and estimated 10-year fatal cardiovascular risk in Switzerland.

BACKGROUND AND AIM: There is an ongoing debate on which obesity marker better predicts cardiovascular disease (CVD). In this study, the relationships between obesity markers and high (>5%) 10-year risk of fatal CVD were assessed. METHODS AND RESULTS: A cross-sectional study was conducted including 3047 women and 2689 men aged 35-75years. Body fat percentage was assessed by tetrapolar bioimpedance. CVD risk was assessed using the SCORE risk function and gender- and age-specific cut points for body fat were derived. The diagnostic accuracy of each obesity marker was evaluated through receiver operating characteristics (ROC) analysis. In men, body fat presented a higher correlation (r=0.31) with 10-year CVD risk than waist/hip ratio (WHR, r=0.22), waist (r=0.22) or BMI (r=0.19); the corresponding values in women were 0.18, 0.15, 0.11 and 0.05, respectively (all p<0.05). In both genders, body fat showed the highest area under the ROC curve (AUC): in men, the AUC (95% confidence interval) were 76.0 (73.8-78.2), 67.3 (64.6-69.9), 65.8 (63.1-68.5) and 60.6 (57.9-63.5) for body fat, WHR, waist and BMI, respectively. In women, the corresponding values were 72.3 (69.2-75.3), 66.6 (63.1-70.2), 64.1 (60.6-67.6) and 58.8 (55.2-62.4). The use of the body fat percentage criterion enabled the capture of three times more subjects with high CVD risk than the BMI criterion, and almost twice as much as the WHR criterion. CONCLUSION: Obesity defined by body fat percentage is more related with 10-year risk of fatal CVD than obesity markers based on WHR, waist or BMI.

IPH gives evidence to NI Assembly Health Committee Inquiry into Obesity

IPH Chief Executive, Dr Jane Wilde gave evidence to the Northern Ireland Assembly Health Committee inquiry into obesity. Dr Wilde recommended the following: Supporting the Department of Health’s strategic approach based on an understanding of the nature and complexity of obesity. Urgent and short term action to coordinate current activities and ensure focus on the most vulnerable. Exploring new forms and incentives to promote cross departmental work. Setting intermediate outcomes and targets Building stronger links between research, policy and practice, for example asking the Health Committee to set up a round table of researchers and policy makers Working systematically and transparently to identify key areas for cooperation with UK, Ireland and Europe Drawing from IPH work and other research, Dr Wilde briefed the Health Committee on the extent and impact of obesity, reasons for rising levels of obesity and the need for a stronger strategic response. She highlighted the importance of cross government action, the responsibilities of those beyond the health sector and the need for stronger evidence-informed policy and practice.

A Tobacco-Free Future - An all-island report on tobacco, inequalities and childhood 2013

A Tobacco-Free Future - An all-island report on tobacco, inequalities and childhood 2013 reveals declines in smoking rates among both children and pregnant women over the past decade, both North and South of the border. This report published by the Institute of Public Health in Ireland (IPH) and the TobaccoFree Research Institute Ireland (TFRI), shows that while tobacco control measures are being successful, disadvantaged children are at particular risk of tobacco-related harms.

Closeness in relationships as a mediator between sexual abuse in childhood or adolescence and psychopathological outcome in adulthood.

The risk of adverse psychological outcomes in adult victims of childhood and adolescent sexual abuse (CSA) has been documented; however, research on possible mediating variables is still required, namely with a clinical perspective. The attachment literature suggests that secure interpersonal relationships may represent such a variable. Twenty-eight women who had experienced episodes of CSA, and 16 control women, were interviewed using Bremner's Early Trauma Inventory and the DSM-IV Global Assessment of Functioning; they also responded to Collins' Relationship Scales Questionnaire, evaluating adult attachment representations in terms of Closeness, Dependence and Anxiety. Subjects with an experience of severe abuse reported significantly more interpersonal distance in relationships (low index of Closeness) than other subjects. The index of psychopathological functioning was correlated with both the severity of abuse and attachment (low index of Closeness). Regression analysis on the sample of abused women revealed that attachment predicted psychopathology when abuse was controlled for, whereas abuse did not predict psychopathology when attachment was controlled for. Therefore, preserving a capacity for closeness with attachment figures in adulthood appears to mediate the consequences of CSA on subsequent psychopathological outcome.

Framework for Preventing and Addressing Overweight and Obesity in Northern Ireland 2012-2022: A Fitter Future for All (PDF 1MB)

A Framework for Preventing and Addressing Overweight and Obesity in NI 2012-2022 This Framework aims to “empower the population of Northern Ireland to make healthy choices, reduce the risk of overweight and obesity related diseases and improve health and wellbeing, by creating an environment that supports and promotes a physically active lifestyle and a healthy diet”. In addition, the following overarching targets have been set: Adults • To reduce the level of obesity by 4% and overweight and obesity by 3% by 2022. Children • A 3% reduction of obesity and 2% reduction of overweight and obesity by 2022åÊThe target is in two parts; the proportion that are obese and the proportion that are overweight and obese. Prevention is typically taken forward through action to address two main areas – improving diet and nutrition, and increasing participation in physical activity. Acknowledging this, two overarching objectives for the Framework have been set: to increase the percentage of people eating a healthy, nutritionally balanced diet; and to increase the percentage of the population meeting the CMO guidelines on physical activity.
