Comparative study of patients knowledge on osteoarthritis treatment options to ACR guidelines

Portuguese population is growing older, according to national data in 2011 the aging index was 129. The number of elderly population is higher than the younger; average life expectancy is 79,2 years (1). Because knee Osteoarthritis increases with age, and according to WHO 80% of these subjects will have some degree of impairment and 25% will not be able to do their daily living activities (2), OA has a big impact on the sustainability of both health and social care as populations grow older. Our goal was to compare current guidelines of managing knee OA, to the degree of information each patient has about their treatment options.info:eu-repo/semantics/publishedVersio

Polymers Confined between Two Parallel Plane Walls

Single three dimensional polymers confined to a slab, i.e. to the region between two parallel plane walls, are studied by Monte Carlo simulations. They are described by $N$-step walks on a simple cubic lattice confined to the region $1 \le z \le D$. The simulations cover both regions $D > R_F$ (where $R_F \sim N^\nu$ is the Flory radius, with $\nu \approx 0.587$), as well as the cross-over region in between. Chain lengths are up to $N=80,000$, slab widths up to D=120. In order to test the analysis program and to check for finite size corrections, we actually studied three different models: (a) Ordinary random walks (mimicking $\Theta$-polymers); (b) Self-avoiding walks (SAW); and (c) Domb-Joyce walks with the self-repulsion tuned to the point where finite size corrections for free (unrestricted) chains are minimal. For the simulations we employ the pruned-enriched-Rosenbluth method (PERM) with Markovian anticipation. In addition to the partition sum (which gives us a direct estimate of the forces exerted onto the walls), we measure the density profiles of monomers and of end points transverse to the slab, and the radial extent of the chain parallel to the walls. All scaling laws and some of the universal amplitude ratios are compared to theoretical predictions.Comment: 8 pages, 14 figures include

Boost the Impact of Continuous Formal Verification in Industry

Software model checking has experienced significant progress in the last two decades, however, one of its major bottlenecks for practical applications remains its scalability and adaptability. Here, we describe an approach to integrate software model checking techniques into the DevOps culture by exploiting practices such as continuous integration and regression tests. In particular, our proposed approach looks at the modifications to the software system since its last verification, and submits them to a continuous formal verification process, guided by a set of regression test cases. Our vision is to focus on the developer in order to integrate formal verification techniques into the developer workflow by using their main software development methodologies and tools.Comment: 7 page

Airway involvement in interstitial lung disease

PURPOSE OF REVIEW: After briefly discussing several ways to approach airway involvement in interstitial lung diseases - by diagnostic methodologies used to assess it, considering different topographical involvement, related to its presence in the diffuse lung diseases with higher prevalence, or from a causal point of view - the author describes in more detail, taking into account recent literature, new proposed entities combining airways (at different levels) and interstitial damage, like airway-centered interstitial fibrosis and acute fibrinous organizing pneumonia. RECENT FINDINGS: These proposed patterns are being discussed, as possible autonomic interstitial lung disease disorders, and also from the perspective of its relationship with the main differential diagnosis, within known interstitial pictures. SUMMARY: Thus, airway-centered interstitial fibrosis and acute fibrinous organizing pneumonia may widen the spectrum of the yet described long list of interstitial lung diseases, and its diagnosis may be considered, under specific circumstances, when there is airway involvement associated with interstitial damage
