Improved classification of rheumatoid arthritis with a score including anti‑acetylated ornithine antibodies
The presence of rheumatoid factor (RF) or anti-cyclic citrullinated peptide (anti-CCP) autoantibodies contributes to the current rheumatoid arthritis (RA) classification criteria. These criteria involve stratification on antibody levels, which limits reproducibility, and underperform in the RA patients
without RF and anti-CCP. Here, we have explored if two anti-acetylated peptide antibodies (AAPA),
anti-acetylated lysine (AcLys) and anti-acetylated ornithine (AcOrn), could improve the performance
of the current criteria. The analysis was done in 1062 prospectively-followed early arthritis (EA)
patients. The anti-AcOrn were more informative than the anti-AcLys, the conventional RA antibodies
and the anti-carbamylated protein antibodies. The anti-AcOrn produced a classification that did not
require antibody levels and showed improved specificity (77.6% vs. 72.6%, p = 0.003) and accuracy
(79.0% vs. 75.8%, p = 0.002) over the current criteria. These improvements were obtained with a
scoring system that values concordance between anti-AcOrn, RF and anti-CCP. No significant gain was
obtained in sensitivity (80.2% vs. 78.8%, p = 0.25) or in improving the classification of the RA patients
lacking RF and anti-CCP, although the anti-AcOrn ranked first among the analysed new antibodies.
Therefore, the anti-AcOrn antibodies could contribute to the improvement of RA classification criteria by exploiting antibody concordance.This work was supported by the Instituto de Salud Carlos III (Spain) through grants

Automatic tree detection and attribute characterization using portable terrestrial lidar
Currently, the implementation of portable laser scanners (PLS) in forest inventories is being studied, since they allow for significantly reduced field-work time and costs when compared to the traditional inventory methods and other LiDAR systems. However, it has been shown that their operability and efficiency are dependent upon the species assessed, and therefore, there is a need for more research assessing different types of stands and species. Additionally, a few studies have been conducted in Eucalyptus stands, one of the tree genus that is most commonly planted around the world. In this study, a PLS system was tested in a Eucalyptus globulus stand to obtain different metrics of individual trees. An automatic methodology to obtain inventory data (individual tree positions, DBH, diameter at different heights, and height of individual trees) was developed using public domain software. The results were compared to results obtained with a static terrestrial laser scanner (TLS). The methodology was able to identify 100% of the trees present in the stand in both the PLS and TLS point clouds. For the PLS point cloud, the RMSE of the DBH obtained was 0.0716, and for the TLS point cloud, it was 0.176. The RMSE for height for the PLS point cloud was 3.415 m, while for the PLS point cloud, it was 10.712 m. This study demonstrates the applicability of PLS systems for the estimation of the metrics of individual trees in adult Eucalyptus globulus stands.Agencia Estatal de Investigación | Ref.

Relación entre la desigualdad económica y desigualdad en el uso del agua
En este trabajo se estudia la posible relación entre la desigualdad económica y la desigualdad en el uso del agua mundial. De la misma manera, se estudian los diferentes indicadores existentes para la medición de la desigualdad, además de poner en práctica dos de ellos. Hemos evaluado la desigualdad de dichas variables para un periodo global(1971-2020) y dos subperiodos. Asimismo, hemos evaluado dicha desigualdad entre las regiones del mundo. <br /
Fever of Unknown Origin: Don’t Forget Kala-Azar Even in Europe
We present the case of a 70-year-old male patient with fever of unknown origin after a long period of convalescence from a previous
admission to a chronic care hospital. During the admission, multiple combinations of antibiotic and antifungal treatments were prescribed,
but with persistent fever and, eventually, neutropenia (200 lymphocytes, 0 neutrophils). Given the suspicion of infection at bone marrow
level, a biopsy was performed as was serology of Leishmania, both diagnostic determinations. Treatment with amphotericin B liposomal
resulted in a good outcome
Influence of the Water Vapour Permeability of Airtight Sheets on the Behaviour of Facade
The air-tightness of the thermal envelope of buildings is one of the measures to reduce their
energy demands in order to achieve global warming reduction targets. To this end, airtight sheets
with different water vapour permeability characteristics are used. The different products studied are
highly dispersed in terms of equivalent air thickness values, leading to confusion. After the analysis
carried out, it is concluded that all airtight sheets are vapour barriers. To clarify whether or not
these sheets are necessary as vapour barriers, a condensation analysis was carried out on 13 different
facades for 3 climate zones with severe winters as defined in Spanish regulations. The results reveal
that interstitial condensation occurs in only 7 of the 39 case studies, with the traditional facades
of brickwork with render causing the greatest problems if the appropriate products are not used.
In these cases, airtight sheets with water vapour barrier characteristics must be applied on the interior
face of the insulating material. In all other cases (32), the airtight sheets must be permeable to water
vapour if it is looked for a more breathable wall to water vapour and a better control of the interior
humidity conditions
Dispensacion de anticonceptivos hormonales orales
El 80% de las mujeres españolas en edad fértil utilizan métodos anticonceptivos. Los anticonceptivos orales hormonales son los que obtienen mayor grado de satisfacción entre las usuarias siendo el segundo método utilizado.
Método
Estudio observacional descriptivo en 7 farmacias de la Comunidad de Madrid. Durante seis meses (enero-junio de 2009) se realizó una entrevista en el mostrador a las usuarias de métodos anticonceptivos hormonales orales para conocer qué tipo de paciente los demanda, si existen factores de riesgo que desaconsejen su utilización y el cumplimiento de la legislación vigente en cuanto a dispensación. Los datos se registraron y se evaluaron posteriormente.
Resultados
Existe un alto número de usuarias (39,3%) que creen que estos medicamentos pueden ser adquiridos sin receta médica en las farmacias comunitarias, por lo que habrá que realizar más educación sanitaria al respecto
Challenges of the general system of social security and health: Prospective for social development in the Atlantic Coast of Colombia
Introducción: Concepción interdisciplinaria de la gestión del sistema de salud en el contexto latinoamericano, de acuerdo con lo establecido por la Organización Mundial de la Salud/ Organización Panamericana de la Salud. El artículo propone una estrategia prospectiva de desarrollo social en la Costa Atlántica de Colombia, para afianzar el funcionamiento, desde lo preventivo y asistencial, del Sistema General de Seguridad Social y Salud colombiano.
Objetivo: Definir, desde una visión prospectiva para el desarrollo social colectivo, los retos del Sistema General de Seguridad Social y Salud colombiano.
Método: Estudio exploratorio, fundamentado en el análisis teórico conceptual que permite derivar el sistema de relaciones de las categorías: gerencia del sistema de salud y desarrollo social colectivo. Se aplica la prospectiva estratégica, mediante el componente empíricoanalítico, a través del cual se visualizan escenarios futuros que direccionen el desarrollo del sistema de salud a partir de la interacción entre sus actores representativos.
Resultados: Se determinaron debilidades relacionadas con la gestión integral del Sistema General de Seguridad Social y Salud colombiano, específicamente en la Costa Atlántica. En esta región del país el escaso uso de técnicas prospectivas debilita la estrategia gerencial y minimiza la posibilidad de asumir retos y prever incertidumbres en uno de los sistemas que, a través de la efectividad de servicios de salud y calidad de vida, supone un indicador de desarrollo social colectivo.
Conclusiones: Necesidad de visionar retos y escenarios para modelar la gestión del Sistema General de Seguridad Social y Salud en la Costa Atlántica de Colombia para afianzar la equidad, la inclusión y la calidad de vida e incrementar los estándares de gestión de la salud en colectivos y comunidades vulneradas.Introduction: There is an interdisciplinary basis conceived for the management of the
health system in the Latin American context, in accordance with the provisions of
WHO/PAHO and that is linked with related disciplines, such as management and
education. This article proposes a prospective strategy of social development in the
Atlantic Coast of Colombia to consolidate its functioning from the preventive and
welfare perspectives in the Colombian's General System of Social Security and Health
(SGSSS, by its acronym in Spanish).
Objective: To define the challenges of the SGSSS from a prospective point of view for
the collective social development.
Method: An exploratory study, based on the conceptual, theoretical analysis to derive
the relations´ system of the following categories: management of the health system,
and collective social development. Strategic prospective is used by the empiricalanalytical component to visualize future scenarios of probable occurrence that address
the development of the health system from the interaction between its representative
actors.
Results: The weaknesses identified were related to the comprehensive management of
the Colombian SGSSS, specifically on the Atlantic Coast, where the limited use of
prospective techniques weakens the management strategy and minimizes the possibility
of assuming challenges and anticipating uncertainties in one of the systems that
through the effectiveness of health services and quality of life warrants responding to
collective social development.
Conclusions: There is a need to view challenges and scenarios for modeling the
management of the SGSSS on the Atlantic Coast of Colombia to strengthen the equity,
inclusion and quality of life, and to increase the standards of health management in
vulnerable groups and communities
