- In this paper, we describe recent architectural and technological advances of the end to end optical network architecture proposed by the DISCUS project (the DIStributed Core for unlimited bandwidth supply for all Users and Services). The two main targets of DISCUS are the principle of equivalence in the access and the reduction of optical-to-electronic conversions in the metro-core network. Technological advances and techno-economic evaluation of Long-Reach Passive Optical Networks (LR-PON), as well as the optimal metro-core node architecture and the required network control plane framework are reported. Network infrastructure sharing challenges are also discussed.

- Objectives To develop evidence-based European League Against Rheumatism (EULAR) recommendations for vaccination in patients with autoimmune inflammatory rheumatic diseases (AIIRD). Methods A EULAR task force was composed of experts representing 11 European countries, consisting of eight rheumatologists, four clinical immunologists, one rheumatologist/clinical immunologist, one infectious disease physician, one nephrologist, one paediatrician/rheumatologist and one clinical epidemiologist. Key questions were formulated and the eligible spectrum of AIIRD, immunosuppressive drugs and vaccines were defined in order to perform a systematic literature review. A search was made of Medline from 1966 to October 2009 as well as abstracts from the EULAR meetings of 2008 and 2009 and the American College of Rheumatology (ACR) meetings of 2007 and 2008. Evidence was graded in categories I-IV, the strength of recommendations was graded in categories A-D and Delphi voting was applied to determine the level of agreement between the experts of the task force. Results Eight key questions and 13 recommendations addressing vaccination in patients with AIIRD were formulated. The strength of each recommendation was determined. Delphi voting revealed a very high level of agreement with the recommendations among the experts of the task force. Finally, a research agenda was proposed. Conclusion Recommendations for vaccination in patients with AIIRD based on the currently available evidence and expert opinion were formulated. More research is needed, particularly regarding the incidence of vaccine-preventable infectious diseases and the safety of vaccination in patients with AIIRD.

Forskningsöversikt (refereegranskat)abstract
- Objectives: To present the systematic literature review (SLR), which formed the basis for the European League Against Rheumatism (EULAR) evidence-based recommendations for vaccination in adult patients with autoimmune inflammatory rheumatic diseases (AIIRD). Methods: AIIRD, vaccines and immunomodulating drugs, as well as eight key questions were defined by the multidisciplinary expert committee commissioned by EULAR for developing the recommendations. A SLR was performed using MedLine through October 2009 and including data from meta-analyses, systematic reviews, randomized trials, and observational studies, excluding case series with participants. Articles in English and regarding patients years of age, were eligible. Results: Several vaccine-preventable infections (VPI) occur more often in AIIRD-patients and most vaccines are efficacious in AIIRD-patients, even when treated with immunomodulating agents, except rituximab. There does not appear to be an increase in vaccination-related harms in vaccinated patients with AIIRD in comparison with unvaccinated patients with AIIRD. However, these studies are underpowered and therefore not conclusive. Conclusion: Based on the current evidence from the literature, recommendations for vaccination in patients with AIIRD were made. However, more research is needed in particular regarding incidence of VPI, harms of vaccination and the influence of (new and established) immunomodulating agents on vaccination efficacy.

- CTB-MPR is a fusion protein between the B subunit of cholera toxin (CTB) andthe membrane-proximal region of gp41 (MPR), the transmembrane envelopeprotein ofHuman immunodeficiency virus 1(HIV-1), and has previously beenshown to induce the production of anti-HIV-1 antibodies with antiviralfunctions. To further improve the design of this candidate vaccine, X-raycrystallography experiments were performed to obtain structural informationabout this fusion protein. Several variants of CTB-MPR were designed,constructed and recombinantly expressed inEscherichia coli. The first variantcontained a flexible GPGP linker between CTB and MPR, and yielded crystalsthat diffracted to a resolution of 2.3 A ̊, but only the CTB region was detectedin the electron-density map. A second variant, in which the CTB was directlyattached to MPR, was shown to destabilize pentamer formation. A thirdconstruct containing a polyalanine linker between CTB and MPR proved tostabilize the pentameric form of the protein during purification. The purificationprocedure was shown to produce a homogeneously pure and monodispersesample for crystallization. Initial crystallization experiments led to pseudo-crystals which were ordered in only two dimensions and were disordered inthe third dimension. Nanocrystals obtained using the same precipitant showedpromising X-ray diffraction to 5 A ̊resolution in femtosecond nanocrystallo-graphy experiments at the Linac Coherent Light Source at the SLAC NationalAccelerator Laboratory. The results demonstrate the utility of femtosecondX-ray crystallography to enable structural analysis based on nano/microcrystalsof a protein for which no macroscopic crystals ordered in three dimensions havebeen observed before.

DISCUS : An End-to-End Solution for Ubiquitous Broadband Optical Access

- Fiber to the premises has promised to increase the capacity in telecommunications access networks for well over 30 years. While it is widely recognized that optical-fiber-based access networks will be a necessity in the shortto medium-term future, its large upfront cost and regulatory issues are pushing many operators to further postpone its deployment, while installing intermediate unambitious solutions such as fiber to the cabinet. Such high investment cost of both network access and core capacity upgrade often derives from poor planning strategies that do not consider the necessity to adequately modify the network architecture to fully exploit the cost benefit that a fiber-centric solution can bring. DISCUS is a European Framework 7 Integrated Project that, building on optical-centric solutions such as long-reach passive optical access and flat optical core, aims to deliver a cost-effective architecture for ubiquitous broadband services. DISCUS analyzes, designs, and demonstrates end-to-end architectures and technologies capable of saving cost and energy by reducing the number of electronic terminations in the network and sharing the deployment costs among a larger number of users compared to current fiber access systems. This article describes the network architecture and the supporting technologies behind DISCUS, giving an overview of the concepts and methodologies that will be used to deliver our end-to-end network solution.
