Laparoscopic Roux-en-Y gastric bypass in patients over the age of 60 years

The prevalence of obesity is increasing even in older patients. Bariatric surgery is often considered more risky in this group, and not necessarily associated with the same benefits as in younger patients. In France, guidelines recommend to assess indication for surgery based on comorbidities and physiological age.

Psychosocial Quality-of-Life, Lifestyle and Adiposity: A Longitudinal Study in Pre-schoolers (Ballabeina Study).

PURPOSE: In obesity prevention, understanding psychosocial influences in early life is pivotal. Reviews reported contradictory results and a lack of longitudinal studies focusing on underlying lifestyle factors. This study tested whether psychosocial Quality-Of-Life (QOL) was associated with pre-schoolers' lifestyle and adiposity changes over one school year and whether lifestyle moderated the latter. It was hypothesised that QOL might not impact adiposity in everybody but that this might depend on preceding lifestyle. METHOD: Longitudinal data from 291 Swiss pre-schoolers (initially 3.9-6.3 years) was available. The following measures were used in longitudinal regressions: psychosocial QOL by PedsQL, adiposity (BMI z-score, waist, fat%), diet (food frequency), sedentary time and accelerometer-based activity. RESULTS: Concerning lifestyle, low psychosocial QOL was only related to unfavourable changes in diet (less fruit β = 0.21 and more fat intake β = -0.28) and lower physical activity (β = 0.21). Longitudinal QOL-adiposity relations appeared only after moderation by lifestyle factors (beta-range 0.13-0.67). Low psychosocial QOL was associated with increased adiposity in children with an unhealthy diet intake or high sedentary time. By contrast, low psychosocial QOL was associated with decreasing adiposity in high fruit consumers or more physically active pre-schoolers. CONCLUSION: Results emphasise the need for testing moderation in the QOL-adiposity relation. An unhealthy diet can be a vulnerability factor and high physical activity a protective factor in QOL-related adiposity. Consequently, QOL and lifestyle should be targeted concurrently in multi-factorial obesity prevention. The environment should be an 'activity encouraging, healthy food zone' that minimises opportunities for stress-induced eating. In addition, appropriate stress coping skills should be acquired.

Estudi de prevalença de sobrepès i obesitat en la població adolescent de Girona

L’obesitat infantil, és un dels problemes de salut pública més greus del segle XXI, on la prevalença ha augmentat de manera alarmant a nivell mundial. Aquesta es defineix com una malaltia crònica i multifactorial, que sol iniciar-se en la infantesa i a l’adolescència. L’objectiu principal d’aquest estudi és conèixer la prevalença de sobrepès i obesitat en la població adolescent de Girona, i relacionar amb aquesta, els hàbits alimentaris, els hàbits d’activitat física, l’entitat de l’institut-escola, hores de son i nivell màxim d’estudis dels progenitors. Material i mètodes: Estudi descriptiu, observacional i transversal sobre una mostra de la població adolescent de Girona de 14 a 16 anys (n=185), els quals se’ls va administrar un qüestionari on es van recollir les variables relacionades amb l’estudi. L’obesitat i el sobrepès es van definir com valors de l’índex de massa corporal iguals o superiors als valors dels percentils 97 i 85, respectivament, de les taules de referencia de la OMS de 2007. Resultats: La prevalença de sobrepès i d’obesitat en la població adolescent de Girona és del 20% i del 3,78%, respectivament. El sobrepès i l’obesitat (23,78%) ha afectat més al sexe masculí (27,7%) respecte el femení (19,8%). S’ha establert relació significativa entre la prevalença de sobrepès i obesitat amb el nivell màxim d’estudis dels progenitors. Hi ha més prevalença de sobrepès i obesitat a l’institut públic en vers el privat amb un 26,7% respecte el 18,5%. Conclusions: Segons la bibliografia consultada, la població adolescent de Girona presenta més elevada la prevalença de sobrepès però no pel que fa la prevalença d’obesitat

FFQ para el estudio del consumo de cacao (portugués)

Cocoa has been highlighted as a food with potential benefits to human health due to it being animportant source of polyphenols. However, few studies show the contribution of cocoa andchocolate products in polyphenol intake. The aim of this work was to develop and validate afood frequency questionnaire (FFQ) evaluating the intake of food products containing cocoa (CFFQ).A sample of university students was recruited to complete the 90-item questionnaire inSpain and therefore in Spanish (http://diposit.ub.edu/dspace/handle/2445/60475) and in Portugalin a Portuguese version, which is the present document. The developed FFQ questionnaire canbe considered as a valid option for assessing the consumption frequency of cocoa- andchocolate-derived products, thereby allowing the evaluation of cocoa polyphenol intake infurther studies.

Banda gástrica ajustável laparoscópica: alternativa técnica

In these paper we are presenting a technical alternative to laparoscopic adjustable gastric banding. From January 1999 to April 2000, 60 patients with mean body mass index (BMI) of 40,7 kg/m2 underwent laparoscopic adjustable gastric banding. The new technique is performed in two steps. In the first step, an isolation instrument (laparoscopic finger) is inserted through the lesser sac, next to the junction of diaphragmatic crura, including the lesser omentum in order to pull the band catheter. The second step separates the lesser omentum from the right side of the stomach.There was no mortality and the morbidity was 11,6% (1 slippage of the band and 6 trocar port seroma). The new technique was performed in all patients with no conversion to open procedure. We didn't have respiratory complications. This technical alternative is safe and easily performed, helping to prevent transoperative perforations.

Complicação da banda gástrica ajustável videolaparoscópica para tratamento da obesidade mórbida: extrusão da banda

Various options for surgical treatment of morbid obesity have been developed with varying results: vertical banded gastroplasty with intestinal by-pass, disabsorptive surgeries and laparoscopic adjustable gastric banding. Although all of them have been effective in weight loss, lower rates of early and late postoperative complications have been described in some procedures. Laparoscopic adjustable silicone gastric banding (LASGB) has a similar principle as vertical banded gastroplasty and it is a minimally invasive procedure, with low systemic and operative problems, but not free of them. We report two rare cases of this complications of LASGB.

Câncer gástrico após gastroplastia para obesidade mórbida

We report a case of patient in whom a gastric remnant cancer developed about five years after a gastric bypass for morbid obesity. We review the literature on gastric cancer after gastroplasty. Access of gastric remnant after gastroplasty (Fobi-Capella) prevents evaluation and treatment of its disorders.

Mecanismos cirúrgicos de controle do diabetes mellitus tipo 2 após cirurgia bariátrica

Type 2 diabetes mellitus is an epidemic health problem. Approximately, 90% of diabetic patients are overweight or are obese. The current increase in the prevalence of obesity has been associated with an increase in the prevalence of type 2 diabetes. Bariatric surgery is the most effective treatment for morbid obese patients in terms of controlling weight and co-morbidities. Sustained normal plasma concentration of glucose has been reported in most diabetic morbid obese patients, which has been managed surgically. Available data show a significant alteration in the production of some gastrointestinal hormones, which might explain the improvement of glucose metabolism following these procedures. Diabetic patient improvements following some bariatric surgeries seems to be an independent factor unrelated to the amount of weight loss. The authors reviewed data published on the effects of bariatric surgery in diabetic patient improvements and the possible mechanisms responsible for this control.

Colangiopancreatografia endoscópica retrógrada transgástrica laparoscópica após cirurgia bariátrica

Access to the gastric remnant and duodenum is lost after Roux-en-Y gastric bypasses for morbid obesity. Laparoscopic transgastric endoscopic retrograde cholangiopancreatography has recently been described to manage biliary problems in such cases. We describe the first brazilian case of management of choledocholithiasis after a Roux-en-Y gastric bypass using this approach.

Mortality rate after open Roux-in-Y gastric bypass: a 10-year follow-up

The prevalence of obesity has increased to epidemic status worldwide. Thousands of morbidly obese individuals undergo bariatric surgery for sustained weight loss; however, mid- and long-term outcomes of this surgery are still uncertain. Our objective was to estimate the 10-year mortality rate, and determine risk factors associated with death in young morbidly obese adults who underwent bariatric surgery. All patients who underwent open Roux-in-Y gastric bypass surgery between 2001 and 2010, covered by an insurance company, were analyzed to determine possible associations between risk factors present at the time of surgery and deaths related and unrelated to the surgery. Among the 4344 patients included in the study, 79% were female with a median age of 34.9 years and median body mass index (BMI) of 42 kg/m2. The 30-day and 10-year mortality rates were 0.55 and 3.34%, respectively, and 53.7% of deaths were related to early or late complications following bariatric surgery. Among these, 42.7% of the deaths were due to sepsis and 24.3% to cardiovascular complications. Male gender, age ≥50 years, BMI ≥50 kg/m2, and hypertension significantly increased the hazard for all deaths (P<0.001). Age ≥50 years, BMI ≥50 kg/m2, and surgeon inexperience elevated the hazard of death from causes related to surgery. Male gender and age ≥50 years were the factors associated with increased mortality from death not related to surgery. The overall risk of death after bariatric surgery was quite low, and half of the deaths were related to the surgery. Older patients and superobese patients were at greater risk of surgery-related deaths, as were patients operated on by less experienced surgeons.

Transition nutritionnelle et facteurs de risque de maladies cardiovasculaires au Bénin : étude dans la ville secondaire de Ouidah et sa périphérie rurale

Ce travail a été réalisé avec l'appui du Centre Collaborateur de l'OMS sur la Transition Nutritionnelle et le Développement (TRANSNUT) de l'Université de Montréal, en collaboration avec deux parténaires du Bénin: l'Institut de Sciences Biomédicales Appliquées (ISBA) de Cotonou et l'Institut Régional de Santé Publique de Ouidah.

Association entre l'insécurité alimentaire et les apports en nutriments chez les Premières Nations de la Colombie-Britannique

Cette étude a pour but de vérifier l’association entre l’insécurité alimentaire et les apports nutritionnels des Premières Nations vivant sur les réserves de la Colombie-Britannique, ainsi que la présence d’interactions de la nourriture traditionnelle dans la relation entre l’insécurité alimentaire et les apports nutritionnels. Un rappel de 24h et le questionnaire sur l’insécurité alimentaire du HFSSM adapté par Santé Canada provenant de la First Nations Food, Nutrition and Environment Study (FNFNES) ont servi pour les analyses statistiques chez 493 femmes et 356 hommes dans 21 communautés de Premières Nations de la Colombie-Britannique. Aucune association entre l’insécurité alimentaire et les apports nutritionnels totaux n’a été observée dans notre échantillon. Par contre, la nourriture traditionnelle interagissait dans la relation entre l’insécurité alimentaire et les apports nutritionnels pour plusieurs nutriments chez les hommes et chez les femmes. Chez les femmes, la qualité nutritionnelle pourrait jouer un rôle important dans la relation entre l’insécurité alimentaire et les apports nutritionnels. Chez les hommes, des différences dans les comportements alimentaires pourraient être associées au manque de nourriture traditionnelle chez ceux ayant manifesté une insécurité alimentaire grave. Enfin, les interactions de la nourriture traditionnelle dans la relation entre l’insécurité alimentaire et les apports nutritionnels laissent croire que les hommes et les femmes souffrant peu ou pas d’insécurité alimentaire ajoutent ce type d’alimentation à leurs apports quotidiens. À l’inverse, ceux et celles qui souffrent d’insécurité alimentaire grave utiliseraient la nourriture traditionnelle pour remplacer la nourriture commerciale.
