Switching from tenofovir disoproxil fumarate to tenofovir alafenamide in antiretroviral regimens for virologically suppressed adults with HIV-1 infection: a randomised, active-controlled, multicentre, open-label, phase 3, non-inferiority study.

BACKGROUND: Antiretroviral regimens containing tenofovir disoproxil fumarate have been associated with renal toxicity and reduced bone mineral density. Tenofovir alafenamide is a novel tenofovir prodrug that reduces tenofovir plasma concentrations by 90%, thereby decreasing off-target side-effects. We aimed to assess whether efficacy, safety, and tolerability were non-inferior in patients switched to a regimen containing tenofovir alafenamide versus in those remaining on one containing tenofovir disoproxil fumarate. METHODS: In this randomised, actively controlled, multicentre, open-label, non-inferiority trial, we recruited HIV-1-infected adults from Gilead clinical studies at 168 sites in 19 countries. Patients were virologically suppressed (HIV-1 RNA <50 copies per mL) with an estimated glomerular filtration rate of 50 mL per min or greater, and were taking one of four tenofovir disoproxil fumarate-containing regimens for at least 96 weeks before enrolment. With use of a third-party computer-generated sequence, patients were randomly assigned (2:1) to receive a once-a-day single-tablet containing elvitegravir 150 mg, cobicistat 150 mg, emtricitabine 200 mg, and tenofovir alafenamide 10 mg (tenofovir alafenamide group) or to carry on taking one of four previous tenofovir disoproxil fumarate-containing regimens (tenofovir disoproxil fumarate group) for 96 weeks. Randomisation was stratified by previous treatment regimen in blocks of six. Patients and treating physicians were not masked to the assigned study regimen; outcome assessors were masked until database lock. The primary endpoint was the proportion of patients who received at least one dose of study drug who had undetectable viral load (HIV-1 RNA <50 copies per mL) at week 48. The non-inferiority margin was 12%. This study was registered with ClinicalTrials.gov, number NCT01815736. FINDINGS: Between April 12, 2013 and April 3, 2014, we enrolled 1443 patients. 959 patients were randomly assigned to the tenofovir alafenamide group and 477 to the tenofovir disoproxil fumarate group. Viral suppression at week 48 was noted in 932 (97%) patients assigned to the tenofovir alafenamide group and in 444 (93%) assigned to the tenofovir disoproxil fumarate group (adjusted difference 4·1%, 95% CI 1·6-6·7), with virological failure noted in ten and six patients, respectively. The number of adverse events was similar between the two groups, but study drug-related adverse events were more common in the tenofovir alafenamide group (204 patients [21%] vs 76 [16%]). Hip and spine bone mineral density and glomerular filtration were each significantly improved in patients in the tenofovir alafenamide group compared with those in the tenofovir disoproxil fumarate group. INTERPRETATION: Switching to a tenofovir alafenamide-containing regimen from one containing tenofovir disoproxil fumarate was non-inferior for maintenance of viral suppression and led to improved bone mineral density and renal function. Longer term follow-up is needed to better understand the clinical impact of these changes. FUNDING: Gilead Sciences.

Mind the Gap. Do Proportional Electoral Systems Foster a More Equal Representation of Women and Men, Poor and Rich ?

Female gender and low income are two markers for groups that have been historically disadvantaged within most societies. The study explores two research questions related to their political representation: 1) Are parties ideologically biased towards the ideological preferences of male and rich citizens? 2) Does the proportionality of the electoral system moderate the degree of underrepresentation of women and poor citizens in the party system? A multilevel analysis of survey data from 24 parliamentary democracies indicates that there is some bias against those with low income and, at a much smaller rate, women. This has systemic consequences for the quality of representation, as the preferences of the complementary groups differ. The proportionality of the electoral system influences the degree of underrepresentation: specifically, larger district magnitudes help closing the considerable gap between rich and poor.

Montrer « l'exorcisme » de Sarah Palin sur le web : enquête(s) sur la portée politique d'images religieuses

En septembre 2008, une vidéo est diffusée sur internet montrant Sarah Palin, alors candidate à la vice-présidence des États-Unis, en train de recevoir « une protection contre la sorcellerie » lors d'une célébration religieuse. La séquence est aussitôt reprise par les médias du monde entier qui s'interrogent et enquêtent sur les rapports entre ces images et l'engagement politique de la républicaine. Cet article suit la circulation de la vidéo au travers de différentes scènes de visibilité, allant des médias généralistes au site internet de l'Église où elle a été tournée, en passant par un blog qui a attiré l'attention publique sur ces images. L'enquête met au jour comment ce film a été compris dans ces différents contextes, et montre les effets de ce travail d'interprétation en 2011, suite à l'avènement du Tea Party et à l'horizon de la prochaine échéance présidentielle. La vidéo qui, en 2008, apparaissait dans les médias généralistes comme une illustration de la « bigoterie » de Palin a contribué à figurer, en 2011, une menace « théocratique » pour la démocratie américaine.

Voting advice applications : impact on voting decisions in the 2011 Swiss national elections

In most democracies voting Advice Applications (VAAs) advising citizens which candidate or party they should vote for become more and more popular. It is therefore crucial to know more about the functioning and the effects of such tools. After some general remarks about the spread of these tools and their possible effects gathered so far in various studies, this paper presents the latest results from a research conducted in the course of the 2011 Swiss national elections. They confirm that VAAs can lead to better informed voters and are likely to have a positive impact on electoral turnout. Additionally it can be shown that the Swiss VAA smartvote made voters change their voting intention and that they voted for a different party. This was particularly advantageous for the Green Liberal Party. At the moment, only a minority of voters rely on the voting recommendation by smartvote. This might change dramatically with the introduction of e-voting. Once people can vote electronically, there are hardly any possibilities to prevent voters from transferring their selection of candidates based on the recommendation given by a VAA into the official electronic ballot paper. If this is possible, e-voting will become more popular than postal voting.

Managing the crises : how did local governments react to the financial crisis in 2008 and what explains the differences ? The case of Swiss municipalities

Swiss municipalities are, to a large extent, responsible for their financial resources. Since these resources primarily depend on income and property taxes from individuals and enterprises, municipality budgets are likely to be directly affected by the current crisis in the financial sector and the economy. This article investigates how municipalities perceived this threat and how they reacted to it. In a nationwide survey conducted at the end of 2009 in all 2596 Swiss municipalities, we asked local secretaries which measures had been launched in order to cope with expected losses in tax income and a possible increase in welfare spending. Did the municipalities rely on Keynesian measures increasing public spending and accepting greater deficits, or did they try to avoid further deficits by using austerity measures and a withdrawal of planned investments? Our results show that only a few municipalities - mainly the bigger ones - expected to be greatly affected by the crisis. Their reactions, however, did not reveal any clear patterns that theory would lead one to expect. Preferences for austerity measures and deficit spending become visible but many municipalities took measures from both theories. The strongest explanatory factors for determining how/why municipalities react are: the municipality's level of affectedness followed by whether or not the municipality belongs to the French-speaking part of the country. Size also has an impact, whereas the strength of the Social Democrat party is negligible. Explaining what kind of measures municipalities are likely to take is more difficult. However, the more a municipality is affected, the more likely it is to stick to austerity measures.

A feasability study of the analysis of the economic outcomes of specialized nutrition in obesity and weight management in Switzerland

The increasing prevalence of obesity and its associated complications requires specialized care to improve outcomes and control health care costs. Obesity is associated with numerous serious and costly medical problems requiring specialized care in managing health. The economic burden of obesity includes increased inpatient and outpatient medical expenditures as well as employer-related issues of absenteeism and associate costs. The objectives of this study are: - To describe the health consequences and the economic burden of obesity, - To review the existing treatment - To argue in favor of a specialized nutritional intervention that has shown to improve health and reduce obesity related health care costs. Therefore, expose the possibility of introducing the specialized nutrition in Switzerland and the feasibility of this project considering the medical trends and reimbursement system in Switzerland The benefits and outcomes for the patients will be the significant weight loss which reduces the severity and risk factors for complications and the improved health and quality of life. Weight loss will be a combination of a diet, exercise and behavioral interventions which are the basic recommendations for obesity treatment in addition to the specialized nutritional support. By nutritional support, we mean products that are intended to provide nutritional support in the dietary management of people with specific diseases and conditions when adequate intake of regular foods is compromised. These products are called, Food for special medical purposes FSMP. They are not intended to treat, cure, prevent, mitigate or have a direct impact on disease in a manner similar to drugs or other medical treatments and should be used under medical supervision. They also provide a low cost alternative to surgery. From a health care system perspective, the specialized nutrition will drive its advantage by reducing the utilization of medical services for obesity associated complications like medication, physician's consultations and surgical interventions arriving to a cost effective care for the hospitals, the health care organizations and the third party payers which are the health insurances.
