Viral load of SARS-CoV-2 across patients and compared to other respiratory viruses.
RT-PCRs to detect SARS-CoV-2 RNA is key to manage the COVID-19 pandemic. We analyzed SARS-CoV-2 viral loads from 22'323 RT-PCR results according to samples types, gender, age, and health units. Viral load did not show any difference across age and appears to be a poor predictor of disease outcome. SARS-CoV-2 viral load showed similar high viral loads than the one observed for RSV and influenza B. The importance of viral load to predict contagiousness and to assess disease progression is discussed
Changing Climate for Quality Assured Regional Qualifications in the Pacific: An innovative collaboration (EU-PacTVET & EQAP)
The Pacific region embraces 22 countries and territories. With more than 7,500 islands over 30 million square kilometres, their combined land mass accounts for only two per cent of this area. Climate change and disasters threaten Pacific economies, livelihoods and cultures, and impact a range of sectors, including natural resources, agriculture, food security, education, public health and infrastructure. The Pacific leaders have continued to reaffirm the ongoing urgency of addressing the challenges posed by, and the impacts of, climate change as a regional priority.1 At the Forty-Sixth Pacific Islands Forum held in September 2015 the leaders of the Pacific small island states reiterated their concerns that climate change remains the single greatest threat to the livelihood, security and well-being of the people of the Pacific. Pacific Island Countries (PICs) recognise a commitment to sustainable development is a national responsibility but also realize that this cannot be achieved without a regional approach. The European Union Pacific Technical, Vocational Education and Training in Sustainable Energy (SE) and Climate Change Adaptation (CCA) Project (EU PacTVET) aims to develop a quality assured regional qualification and accreditation process. This paper reflects discussions, views and validations from members of government agencies, private industry, training providers, non-government organisations, community groups, donors, and industry associations surrounding a regional accreditation strategy
Professionalizing the “resilience” sector in the Pacific Islands Region: Formal education for capacity building
Increasingly practitioners and policy makers working across the globe are recognising the importance of bringing together disaster risk management (DRM) and climate change adaptation (CCA). This broader Pacific understanding of climate change as a slow-acting disaster has been adopted by the European Union Pacific Technical Vocational Education and Training on Sustainable Energy and Climate Change Adaptation Project (EU PacTVET) project in introducing innovative initiatives to address wide ranging needs.
A key barrier to improving national resilience to disaster risk and climate change impacts has been identified as a lack of capacity and expertise at all levels resulting from the absence of sustainable accredited and quality assured formal training programmes in the DRM and CCA sectors.
A key issue is providing an accreditation and quality assurance mechanism for formal training shared across the region through the national delivery of regionally quality assured qualifications in Resilience (CCA and DRM).
TVET training modules and tools developed under the EU PacTVET project will be reviewed by industry and the scientific community through the Pacific Regional Federation of Resilience Practitioners. This professional association alongside the development of regional qualifications is ground breaking and providing global leadership and will ensure the sustainability of the project’s outcomes
Informer, consulter, concerter, codécider pour aménager : Dispositifs de partage des informations et des connaissances pour les processus d'aménagement concerté (DPICPAC) : rapport final
Ce projet applique une approche interdisciplinaire afin de tester l'hypothèse générale et communément admise que la disponibilité et la pertinence de l'information sont cruciaux pour le succès des processus d'aménagement du territoire participatifs (ou collaboratifs) qui impliquent plusieurs groupes d'acteurs, y compris fonctionnaires, des professionnels, des représentants des propriétaires fonciers et du grand public. Cette hypothèse est fondée sur le point de vue "instrumental" que lorsque l'information appropriée est disponible au moment opportun dans le processus de planification, alors il favorisera la réussite de ce processus. Une deuxième hypothèse fondée sur les principes de la «gouvernance» attribue une importance primordiale aux motivations de tous les acteurs et institutions représentés dans le processus de planification. Une troisième hypothèse que la négociation d'un ensemble de règles concernant les rôles et les responsabilités des acteurs et des institutions ainsi que la disponibilité de données appropriées, de statistiques et d'informations sont nécessaires pour une planification collaborative réussie. Cette recherche comprend des études de cas dans la région de langue française de la Suisse (Genève et Lausanne) dans le but d'analyser et d'expliquer comment et pourquoi les statistiques et les informations disponibles peuvent ou non être utilisés efficacement dans les processus décisionnels. La recherche propose un ensemble de lignes directrices pour l'application efficace de ces types de processus dans le futur
PrivateRide: A Privacy-Enhanced Ride-Hailing Service
In the past few years, we have witnessed a rise in the popularity of ride-hailing services (RHSs), an on-line marketplace that enables accredited drivers to use their own cars to drive ride-hailing users. Unlike other transportation services, RHSs raise significant privacy concerns, as providers are able to track the precise mobility patterns of millions of riders worldwide. We present the first survey and analysis of the privacy threats in RHSs. Our analysis exposes high-risk privacy threats that do not occur in conventional taxi services. Therefore, we pro- pose PrivateRide, a privacy-enhancing and practical solu- tion that offers anonymity and location privacy for riders, and protects drivers’ information from harvesting attacks. PrivateRide lowers the high-risk privacy threats in RHSs to a level that is at least as low as that of many taxi services. Using real data-sets from Uber and taxi rides, we show that PrivateRide significantly enhances riders’ privacy, while preserving tangible accuracy in ride matching and fare calculation, with only negligible effects on convenience. Moreover, by using our Android implementation for experimental evaluations, we show that PrivateRide’s overhead during ride setup is negligible. In short, we enable privacy- conscious riders to achieve levels of privacy that are not possible in current RHSs and even in some conventional taxi services, thereby offering a potential business differentiator
Tumour biology, metastatic sites and taxanes sensitivity as determinants of eribulin mesylate efficacy in breast cancer: results from the ERIBEX retrospective, international, multicenter study.
BACKGROUND: Our retrospective, international study aimed at evaluating the activity and safety of eribulin mesylate (EM) in pretreated metastatic breast cancer (MBC) in a routine clinical setting.
METHODS: Patients treated with EM for a locally advanced or MBC between March 2011 and January 2014 were included in the study. Clinical and biological assessment of toxicity was performed at each visit. Tumour response was assessed every 3 cycles of treatment. A database was created to collect clinical, pathological and treatment data.
RESULTS: Two hundred and fifty-eight patients were included in the study. Median age was 59 years old. Tumours were Hormone Receptor (HR)-positive (73.3 %) HER2-positive (10.2 %), and triple negative (TN, 22.5 %). 86.4 % of the patients presented with visceral metastases, mainly in the liver (67.4 %). Median previous metastatic chemotherapies number was 4 [1-9]. Previous treatments included anthracyclines and/or taxanes (100 %) and capecitabine (90.7 %). Median number of EM cycles was 5 [1-19]. The relative dose intensity was 0.917. At the time of analysis (median follow-up of 13.9 months), 42.3 % of the patients were still alive. The objective response rate was 25.2 % (95 %CI: 20-31) with a 36.1 % clinical benefit rate (CBR). Median time to progression (TTP) and overall survival were 3.97 (95 %CI: 3.25-4.3) and 11.2 (95 %CI: 9.3-12.1) months, respectively. One- and 2-year survival rates were 45.5 and 8.5 %, respectively. In multivariate analysis, HER2 positivity (HR = 0.29), the presence of lung metastases (HR = 2.49) and primary taxanes resistance (HR = 2.36) were the only three independent CBR predictive factors, while HR positivity (HR = 0.67), the presence of lung metastases (HR = 1.52) and primary taxanes resistance (HR = 1.50) were the only three TTP independent prognostic factors. Treatment was globally well tolerated. Most common grade 3-4 toxicities were neutropenia (20.9 %), peripheral neuropathy (3.9 %), anaemia (1.6 %), liver dysfunction (0.8 %) and thrombocytopenia (0.4 %). Thirteen patients (5 %) developed febrile neutropenia.
CONCLUSION: EM is an effective new option in heavily pretreated MBC, with a favourable efficacy/safety ratio in a clinical practice setting. Our results comfort the use of this new molecule and pledge for the evaluation of EM-trastuzumab combination in this setting. Tumour biology, primary taxanes sensitivity and metastatic sites could represent useful predictive and prognostic factors

Numerical simulation of fluid flow, solidification and defects in high pressure die casting (HPDC) process
The high pressure die casting process is extensively used to manufacture light metal parts with high productivity. A major drawback of the process is the relatively high variability in mechanical properties and poor repeatability between casting cycles, limiting the achievement of weight reduction through lighter design. Although it has been established that mechanical properties are adversely affected by casting defects, the origin of the relatively high randomness in the HPDC process is not well understood. Numerical simulation is a powerful and cost-effective tool to address this question, as it gives access to quantities that are difficult to obtain experimentally. A numerical simulation approach based on the finite element casting software ProCAST has been developed. The model was applied to the casting of aluminium tensile test samples, which were used to measure the tensile properties of the alloy. Simulation permitted the study of fluid flow, solidification and defect formation during each stage of the HPDC process: pouring, injection and cooling. Air entrapment and porosity distribution in the cast part were predicted. The results were compared with temperature measurements, porosity observations and solid distribution in the sleeve prior to injection. Although the results are still very preliminary, some trends could be established between the level of turbulence of the melt during injection and reduced elongation.This project is financially supported by EPSRC UK in the EPSRC Centre for Innovative Manufacturing in Liquid Metal Engineering (The EPSRC Centre — LiME)
