Nouvelles directives assécurologiques pour la prise en charge de la chirurgie bariatrique: conséquences pratiques [New guidelines for bariatric surgery care: practical implications].

From the 1st of January 2011, new conditions have been validated in which surgery for weight loss is borne by the basic insurance. These are very significant changes compared to the old criteria. Indeed, on one hand, patients with BMI > or = 35 kg/m2 may, without age limit and in the absence of comorbidities benefit from surgery without prior request to the medical council health insurance company concerned. On the other hand, the notion of a minimum casuistry is for the first time introduced in centers performing this type of intervention. In addition, certified centers are required to follow standard procedures for the patients' teaching and follow up.

A theoretical and practical study on linear reforms of dual taxes

We extend the linear reforms introduced by Pf¨ahler (1984) to the case of dual taxes. We study the relative effect that linear dual tax cuts have on the inequality of income distribution -a symmetrical study can be made for dual linear tax hikes-. We also introduce measures of the degree of progressivity for dual taxes and show that they can be connected to the Lorenz dominance criterion. Additionally, we study the tax liability elasticity of each of the reforms proposed. Finally, by means of a microsimulation model and a considerably large data set of taxpayers drawn from 2004 Spanish Income Tax Return population, 1) we compare different yield-equivalent tax cuts applied to the Spanish dual income tax and 2) we investigate how much income redistribution the dual tax reform (Act ‘35/2006’) introduced with respect to the previous tax.

Native-like, long synthetic peptides as components of sub-unit vaccines: practical and theoretical considerations for their use in humans.

Vaccines have been used as a successful tool in medicine by way of controlling many major diseases. In spite of this, vaccines today represent only a handful of all infectious diseases. Therefore, there is a pressing demand for improvements of existing vaccines with particular reference to higher efficacy and undisputed safety profiles. To this effect, as an alternative to available vaccine technologies, there has been a drive to develop vaccine candidate polypeptides by chemical synthesis. In our laboratory, we have recently developed a technology to manufacture long synthetic peptides of up to 130 residues, which are correctly folded and biologically active. This paper discusses the advantages of the molecularly defined, long synthetic peptide approach in the context of vaccine design, development and use in human vaccination.

Clinical review: practical recommendations on the management of perioperative heart failure in cardiac surgery.

Acute cardiovascular dysfunction occurs perioperatively in more than 20% of cardiosurgical patients, yet current acute heart failure (HF) classification is not applicable to this period. Indicators of major perioperative risk include unstable coronary syndromes, decompensated HF, significant arrhythmias and valvular disease. Clinical risk factors include history of heart disease, compensated HF, cerebrovascular disease, presence of diabetes mellitus, renal insufficiency and high-risk surgery. EuroSCORE reliably predicts perioperative cardiovascular alteration in patients aged less than 80 years. Preoperative B-type natriuretic peptide level is an additional risk stratification factor. Aggressively preserving heart function during cardiosurgery is a major goal. Volatile anaesthetics and levosimendan seem to be promising cardioprotective agents, but large trials are still needed to assess the best cardioprotective agent(s) and optimal protocol(s). The aim of monitoring is early detection and assessment of mechanisms of perioperative cardiovascular dysfunction. Ideally, volume status should be assessed by 'dynamic' measurement of haemodynamic parameters. Assess heart function first by echocardiography, then using a pulmonary artery catheter (especially in right heart dysfunction). If volaemia and heart function are in the normal range, cardiovascular dysfunction is very likely related to vascular dysfunction. In treating myocardial dysfunction, consider the following options, either alone or in combination: low-to-moderate doses of dobutamine and epinephrine, milrinone or levosimendan. In vasoplegia-induced hypotension, use norepinephrine to maintain adequate perfusion pressure. Exclude hypovolaemia in patients under vasopressors, through repeated volume assessments. Optimal perioperative use of inotropes/vasopressors in cardiosurgery remains controversial, and further large multinational studies are needed. Cardiosurgical perioperative classification of cardiac impairment should be based on time of occurrence (precardiotomy, failure to wean, postcardiotomy) and haemodynamic severity of the patient's condition (crash and burn, deteriorating fast, stable but inotrope dependent). In heart dysfunction with suspected coronary hypoperfusion, an intra-aortic balloon pump is highly recommended. A ventricular assist device should be considered before end organ dysfunction becomes evident. Extra-corporeal membrane oxygenation is an elegant solution as a bridge to recovery and/or decision making. This paper offers practical recommendations for management of perioperative HF in cardiosurgery based on European experts' opinion. It also emphasizes the need for large surveys and studies to assess the optimal way to manage perioperative HF in cardiac surgery.

Propositions pratiques d'utilisation des ultrasons quantitatifs osseux dans le management de l'ostéoporose [Practical proposals for the use of quantitative bone ultrasound in the management of osteoporosis]

As an emerging alternative to DXA, there is a growing interest in the use of quantitative ultrasound (QUS) measurements for the non invasive assessment of fracture risk in the management of osteoporosis. While the potential of QUS in the management of osteoporosis have been highly recognized by the scientific community and granted by the majority of the international bone disease organizations, it becomes important to develop strategies how to use ultrasound clinically. Our paper is highlighting Swiss operational clinical propositions for 2 QUS devices sold in Switzerland, on how to use the QUS in the management of osteoporosis.

Creació de recursos digitals per a la innovació docent en Geologia Estructural i Tectònica

El projecte ha estat dedicat a l’elaboració d’una sèrie de recursos didàctics en format digital per a l’ensenyament de les matèries de Geologia Estructural i Tectònica en titulacions universitàries relacionades amb les Ciències de la Terra. L’objectiu és la millora de la formació i del rendiment dels estudiants mitjançant l’elaboració d’activitats de suport no presencials que fomentin l’autoaprenentatge i l’autoregulació per part de l’estudiant. Les activitats intenten aprofitar les noves eines informàtiques disponibles i fomentar l’accés mitjançant la xarxa. El material que s’elabora en el marc del projecte consisteix en: 1) un fons documental d’imatges relacionades amb la Geologia Estructural i la Tectònica amb explicació, disponibles en xarxa i accessibles per motors específics de cerca, 2) un conjunt d’exercicis i casos pràctics, alguns d’ells resolts, i 3) sortides de camp virtuals d’una regió geològica que permeten proposar activitats prèvies a una pràctica presencial de camp o desenvolupar la pràctica a nivell completament autònom. Per aconseguir aquests objectius, les tasques realitzades són: la compilació i digitalització de la base d'imatges d'exemples naturals d'estructures geològiques de deformació de que disposàvem, junt amb la redacció de material explicatiu (text i figures), la selecció d'un conjunt d'exercicis de la disciplina, i la preparació de dades de camp per a la realització de les sortides virtuals. Paral•lelament, aquest material s'ha estat processant per a la seva disposició en xarxa com un recurs lliure y obert, accessible en una website i domini específics (plataforma REDITEC).
