Ätiologie und Management der Gicht [The etiology and management of gout].

Gout is an inflammatory arthritis caused by monosodium urate (MSU) crystal deposits in and around the joint. The formation of urinary calculi can also occur in gout, but are less common than arthritis. Gout usually presents with recurrent episodes of joint inflammation, which over time lead to tophus formation and joint destruction. In the last decade, significant advances have been made regarding not only the epidemiology and genetics of gout and hyperuricemia but also the mechanisms of inflammation and treatment of gout. In addition, knowledge concerning the key role of interleukin 1 (IL-1) has provided new therapeutic perspectives. However, the current management of gout is often suboptimal, with many Patienten either not receiving adequate treatment or being unable to tolerate existing treatments. New therapeutic agents provide interesting new options for Patienten with difficult-to-treat gouty arthritis.The English full-text version of this is available at SpringerLink (under "Supplemental").

Mynodbcsv: Lightweight Zero-Config Database Solution for Handling Very Large CSV Files.

Volumes of data used in science and industry are growing rapidly. When researchers face the challenge of analyzing them, their format is often the first obstacle. Lack of standardized ways of exploring different data layouts requires an effort each time to solve the problem from scratch. Possibility to access data in a rich, uniform manner, e.g. using Structured Query Language (SQL) would offer expressiveness and user-friendliness. Comma-separated values (CSV) are one of the most common data storage formats. Despite its simplicity, with growing file size handling it becomes non-trivial. Importing CSVs into existing databases is time-consuming and troublesome, or even impossible if its horizontal dimension reaches thousands of columns. Most databases are optimized for handling large number of rows rather than columns, therefore, performance for datasets with non-typical layouts is often unacceptable. Other challenges include schema creation, updates and repeated data imports. To address the above-mentioned problems, I present a system for accessing very large CSV-based datasets by means of SQL. It's characterized by: "no copy" approach - data stay mostly in the CSV files; "zero configuration" - no need to specify database schema; written in C++, with boost [1], SQLite [2] and Qt [3], doesn't require installation and has very small size; query rewriting, dynamic creation of indices for appropriate columns and static data retrieval directly from CSV files ensure efficient plan execution; effortless support for millions of columns; due to per-value typing, using mixed text/numbers data is easy; very simple network protocol provides efficient interface for MATLAB and reduces implementation time for other languages. The software is available as freeware along with educational videos on its website [4]. It doesn't need any prerequisites to run, as all of the libraries are included in the distribution package. I test it against existing database solutions using a battery of benchmarks and discuss the results.

Building the future: the Brazilian university library in 2010

Information technology will affect academic activities as well as the nature of the high education sector. This sector besides the need to assimilate these technologies will need to attend the requisites of market globalization and, as consequence, all theses changes will be reflected in the university library. Prospectives impacts will affect the structure (emphasis in user services, outsourcing of several services), in the financing aspect (growing of consortia in order to reduce costs), in services (electronic reference, support to long distance education programs, intelligent agents) and in the clientele (attending the great demand por high education which implies a diversity of people).

The PEDRO (Pocketable Electronic Devices in Radiation Oncology) project: how clinical practice is changing among young radiation oncologists.

Purpose. To evaluate the impact of mobile devices and apps on the daily clinical activity of young radiation oncologists. Methods. A web-based questionnaire was sent to 382 young (≤40 years) members of the Italian Association of Radiation Oncology (AIRO). The 14 items investigated the diffusion of mobile devices (smartphones and/or tablets), their impact on daily clinical activity, and possible differences perceived by the participants over time. Results. A total of 158 questionnaires were available for statistical evaluation (response rate 41%). Up to 75% of respondents declared they used an electronic device during their clinical activity. Conversely, 82% considered the impact of smartphones/tables on daily practice low to moderate. Daily device use increased significantly from 2009 to 2012, with high daily use rates rising from 5% to 39.9%. Fulfillment of professional needs was declared by less than 42% of respondents and compliance with app indications by 32%. Almost all physicians desired in 2012 a comprehensive website concerning a variety of apps covering radiation oncologists' needs. Conclusions. Mobile devices are widely used by young Italian radiation oncologists in their daily clinical practice, while the indications so obtained are not always followed. Nevertheless, it would be important to verify the consistency of information found within apps, in order to avoid potential errors that might be detrimental to patients.

Working in a digital world: new leadership practices for the development of a digital library workforce

Digital library developments are part of a global move in many sectors of society toward virtual work and electronic services made possible by the advances in information technology. This environment requires new attitudes and skills in the workforce and therefore leaders who understand the global changes underlying the new information economy and how to lead and develop such a workforce. This article explores ways to develop human resources and stimulate creativity to capitalize on the immense potential of digital libraries to educate and empower social change. There is a shortage of technically skilled workers and even more so of innovators. Retention and recruitment is one of the greatest obstacles to developing digital library services and information products.

ETDs, NDLTD, and open access: a 5S perspective

Worldwide initiatives toward digital library (DL) support for electronic theses and dissertations (ETDs), facilitated by the work of the Networked Digital Library of Theses and Dissertations (NDLTD), are a key part of the move toward open access. When all graduate students learn to use openly available ETDs, and have experience with authoring and submission in connection with their own research results, it will be easy for them to continue these efforts through other contributions to open access. When all universities support ETD activities, they will be key participants in institutional repositories and open access, and will have engaged in discussion and infrastructure development supportive of further open access activities. Understanding of open access also can be facilitated through modeling of all of these efforts using the 5S framework, considering the key aspects of DL development: Societies, Scenarios, Spaces, Structures, and Streams.

Ètica a través de la literatura. La reflexió moral a través del text literari.

La tradició que relaciona l"Ètica amb la Literatura remunta als textos grecs més clàssics on els herois, ben dibuixats per l"autor, presentaven el perfil de l"ideal a seguir per tal que generacions d"homes i dones s"hi emmirallessin tot tractant d"imitar en les seves vides, si no les gestes, les actituds i les virtuts que els herois llegendaris encarnaven. Només cal parar esment en el pes que en la vida d"Alexandre el Gran tingué la presentació que Homer fa d"Aquileu, un heroi que preferí la glòria immortal a un envelliment plàcid a la vora del foc.

Reproducibility of Fatmax and Fat Oxidation Rates during Exercise in Recreationally Trained Males.

Aerobic exercise training performed at the intensity eliciting maximal fat oxidation (Fatmax) has been shown to improve the metabolic profile of obese patients. However, limited information is available on the reproducibility of Fatmax and related physiological measures. The aim of this study was to assess the intra-individual variability of: a) Fatmax measurements determined using three different data analysis approaches and b) fat and carbohydrate oxidation rates at rest and at each stage of an individualized graded test. Fifteen healthy males [body mass index 23.1±0.6 kg/m2, maximal oxygen consumption ([Formula: see text]) 52.0±2.0 ml/kg/min] completed a maximal test and two identical submaximal incremental tests on ergocycle (30-min rest followed by 5-min stages with increments of 7.5% of the maximal power output). Fat and carbohydrate oxidation rates were determined using indirect calorimetry. Fatmax was determined with three approaches: the sine model (SIN), measured values (MV) and 3rd polynomial curve (P3). Intra-individual coefficients of variation (CVs) and limits of agreement were calculated. CV for Fatmax determined with SIN was 16.4% and tended to be lower than with P3 and MV (18.6% and 20.8%, respectively). Limits of agreement for Fatmax were -2±27% of [Formula: see text] with SIN, -4±32 with P3 and -4±28 with MV. CVs of oxygen uptake, carbon dioxide production and respiratory exchange rate were <10% at rest and <5% during exercise. Conversely, CVs of fat oxidation rates (20% at rest and 24-49% during exercise) and carbohydrate oxidation rates (33.5% at rest, 8.5-12.9% during exercise) were higher. The intra-individual variability of Fatmax and fat oxidation rates was high (CV>15%), regardless of the data analysis approach employed. Further research on the determinants of the variability of Fatmax and fat oxidation rates is required.

Consultors i lingüistes: quan el producte de l'empresa és un text

En la societat de la informació, comunicar el coneixement expert s'ha convertit en un producte comercial de primera magnitud. Les empreses de consultoria proporcionen la informació que altres empreses i organitzacions necessiten a l'hora de prendre decisions estratègiques. En aquest context, els informes de consultoria s'erigeixen com un nou gènere textual de gran rellevància que, no obstant això, els lingüistes encara no han atès adequadament. Els experts en llenguatge han de ser capaços de subministrar als consultors les eines i els recursos adequats perquè els documents que elaborin siguin eficaços. Només d¿aquesta manera és possible l'optimització d'aquest tipus de textos.

La llengua i la literatura catalanes en els llibres de text de l'època franquista

L'objectiu d'aquest article és fer conéixer els resultats d'un estudi sobre la visió que els llibres de text de I'época franquista donaven de la llengua i la literatura catalanes. S'han estudiat molts aspectes de la política educativa del régim franquista i de l'acció repressora contra la llengua i la cultura catalanes; en aquests estudis, pero, no s'ha utilitzat gaire una font importantíssima per a conéixer la ideologia que s'intentava de transmetre a través del sistema escolar: els llibres de text. És per aixo que m'ha semblat oportú de realitzar una analisi deis llibres de text de literatura per veure fins a quin punt aquests llibres reflectien la política anihiladora de la llengua i de la cultura catalanes empresa pel régim franquista.

Alguns aspectes formals de la traducció llatina de l'Alcorà de Robert de Ketton (ca. 1141-1143) i la seva relació amb el text original àrab

En el marc de la història de la transmissió escrita de l'Alcorà (al-Qur'an), l'article fa referència a l'evolució de la forma i l'estructura del text en relació amb l'oralitat del missatge original, a l'existència de diferents tradicions textuals en el si de la comunitat islàmica i al seu reflex en les traduccions. L'atenció se centra, sobretot, en la primera traducció sencera coneguda de l'Alcorà al llatí, realitzada per Robert de Ketton (ca. 1141-1143) a la Vall de l'Ebre, i se'n destaca el valor documental com a testimoni contemporani d'una tradició magribina i andalusina de tractament del text.
