Interdisciplinary European guidelines on surgery of severe obesity

W 2005 roku, dzięki wspólnemu wysiłkowi głównych europejskich towarzystw naukowych aktywnych na polu leczenia otyłości został powołany zespół ekspertów nazwany Bariatryczno-Naukową Grupą Badawczą (BSCG). Towarzystwami, które stworzyły ten zespół i oddelegowały swoich przedstawicieli do prac w opracowaniu wytycznych były: Międzynarodowe Towarzystwo Chirurgicznego Leczenia Otyłości (IFSO), Oddział Europejski Międzynarodowego Towarzystwa Chirurgicznego Leczenia Otyłości (IFSO-EC), Europejskie Towarzystwo Badań nad Otyłością (EASO), Europejska Grupa ds. Otyłości u Dzieci (ECOG) (razem z Międzynarodową Grupą Zwalczania Otyłości). Bariatryczno-Naukowa Grupa Badawcza składała się z władz reprezentujących powyższe towarzystwa (czterech czynnych przewodniczących, dwóch byłych, jeden honorowy, dwóch dyrektorów wykonawczych), a także najwybitniejszych ekspertów w tej dziedzinie. Skład BSCG pozwolił na całościowe objęcie zagadnienia leczenia otyłości olbrzymiej z uwzględnieniem różnorodności geograficznej i etnicznej Europy. Członkowie BSCG odbyli wiele spotkań poświęconych stworzeniu wytycznych, które odzwierciedlałyby współczesną wiedzę i doświadczenie w zakresie leczenia otyłości olbrzymiej.In 2005, for the first time in European history, an extraordinary expert panel named BSCG (Bariatric Scientific Collaborative Group), was appointed through joint effort of the major European scientific societies which are active in the field of obesity management. Societies that constituted this panel were: IFSO - International Federation for the Surgery of Obesity, IFSO-EC - International Federation for the Surgery of Obesity - European Chapter, EASO - European Association for Study of Obesity, ECOG - European Childhood Obesity Group, together with the IOTF (International Obesity Task Force) which was represented during the completion process by its representative. The BSCG was composed not only of the top officers representing the respective scientific societies (four acting presidents, two past presidents, one honorary president, two executive directors), but was balanced with the presence of many other key opinion leaders in the field of obesity. The BSCG composition allowed the coverage of key disciplines in comprehensive obesity management, as well as reflecting European geographical and ethnic diversity. This joint BSCG expert panel convened several meetings which were entirely focused on guidelines creation, during the past 2 years. There was a specific effort to develop clinical guidelines, which will reflect current knowledge, expertise and evidence based data on morbid obesity treatment

BariSurg trial: Sleeve gastrectomy versus Roux-en-Y gastric bypass in obese patients with BMI 35–60 kg/m2 – a multi-centre randomized patient and observer blind non-inferiority trial

Background: Roux-en-Ygastric bypass (RYGB) and sleeve gastrectomy (SG) rank among the most frequently applied bariatric procedures worldwide due to their positive risk/benefit correlation. A systematic review revealed a similar excess weight loss (EWL) 2 years postoperatively between SG and RYGB. However, there is a lack of randomized controlled multi-centre trials comparing SG and RYGB, not only concerning EWL, but also in terms of remission of obesity-related co-morbidities, gastroesophageal reflux disease (GERD) and quality of life (QoL) in the mid- and long-term. Methods: The BariSurg trial was designed as a multi-centre, randomized controlled patient and observer blind trial. The trial protocol was approved by the corresponding ethics committees of the centres. To demonstrate EWL non-inferiority of SG compared to RYGB, power calculation was performed according to a non-inferiority study design. Morbidity, mortality, remission of obesity-related co-morbidities, GERD course and QoL are major secondary endpoints. 248 patients between 18 and 70 years, with a body mass index (BMI) between 35–60 kg/m2 and indication for bariatric surgery according to the most recent German S3-guidelines will be randomized. The primary and secondary endpoints will be assessed prior to surgery and afterwards at discharge and at the time points 3–6, 12, 24, 36, 48 and 60 months postoperatively. Discussion: With its five year follow-up, the BariSurg-trial will provide further evidence based data concerning the impact of SG and RYGB on EWL, remission of obesity-related co-morbidities, the course of GERD and QoL. Trial registration: The trial protocol has been registered in the German Clinical Trials Register DRKS0000476

The History and Prehistory of Natural-Language Semantics

Contemporary natural-language semantics began with the assumption that the meaning of a sentence could be modeled by a single truth condition, or by an entity with a truth-condition. But with the recent explosion of dynamic semantics and pragmatics and of work on non- truth-conditional dimensions of linguistic meaning, we are now in the midst of a shift away from a truth-condition-centric view and toward the idea that a sentence’s meaning must be spelled out in terms of its various roles in conversation. This communicative turn in semantics raises historical questions: Why was truth-conditional semantics dominant in the first place, and why were the phenomena now driving the communicative turn initially ignored or misunderstood by truth-conditional semanticists? I offer a historical answer to both questions. The history of natural-language semantics—springing from the work of Donald Davidson and Richard Montague—began with a methodological toolkit that Frege, Tarski, Carnap, and others had created to better understand artificial languages. For them, the study of linguistic meaning was subservient to other explanatory goals in logic, philosophy, and the foundations of mathematics, and this subservience was reflected in the fact that they idealized away from all aspects of meaning that get in the way of a one-to-one correspondence between sentences and truth-conditions. The truth-conditional beginnings of natural- language semantics are best explained by the fact that, upon turning their attention to the empirical study of natural language, Davidson and Montague adopted the methodological toolkit assembled by Frege, Tarski, and Carnap and, along with it, their idealization away from non-truth-conditional semantic phenomena. But this pivot in explana- tory priorities toward natural language itself rendered the adoption of the truth-conditional idealization inappropriate. Lifting the truth-conditional idealization has forced semanticists to upend the conception of linguistic meaning that was originally embodied in their methodology

Proximal (classic) gastric bypass

The intention of this procedure is a restriction of the size of the stomach by cutting it proximally and the creation of malabsorption by dividing the small intestine into an alimentary (Roux limb) and a biliopancreatic segment (Fig. 3.1). Both goals (restriction and malabsorption) are reached in one operation; it is therefore referred to as “combined procedure.”SCOPUS: ch.binfo:eu-repo/semantics/publishe
