Chronic tendinitis versus tendinosis in podiatric pathology. Cytological and histological update

Gran parte de las lesiones que se depositan en nuestro pie se encuentran en la estructura tendinosa por lo que consideramos de interés actualizar los conocimientos sobre esta y sus tejidos. A continuación realizaremos un trabajo de revisión con el fin de actualizar conceptos sobre las lesiones tendinosas que nos podrán ayudar a conocer y mejorar el diagnostico etiológico así como la actividad terapéutica que desarrollamos en nuestra actividad clínica.Largely about injuries that appears in our feet, we can find into the tendinous structure, so its really necessary to refresh the knowledge about tendon structure an tissues. Below, we´ll do a review so we can get the new ideas about injuries tendon so it helps us to improve our aetiology diagnosis and treatments that we do in our clinical activity

ERK5 signalling pathway is a novel target of sorafenib: Implication in EGF biology

© 2021 The Authors.Sorafenib is a multikinase inhibitor widely used in cancer therapy with an antitumour effect related to biological processes as proliferation, migration or invasion, among others. Initially designed as a Raf inhibitor, Sorafenib was later shown to also block key molecules in tumour progression such as VEGFR and PDGFR. In addition, sorafenib has been connected with key signalling pathways in cancer such as EGFR/EGF. However, no definitive clue about the molecular mechanism linking sorafenib and EGF signalling pathway has been established so far. Our data in HeLa, U2OS, A549 and HEK293T cells, based on in silico, chemical and genetic approaches demonstrate that the MEK5/ERK5 signalling pathway is a novel target of sorafenib. In addition, our data show how sorafenib is able to block MEK5-dependent phosphorylation of ERK5 in the Ser218/Tyr220, affecting the transcriptional activation associated with ERK5. Moreover, we demonstrate that some of the effects of this kinase inhibitor onto EGF biological responses, such as progression through cell cycle or migration, are mediated through the effect exerted onto ERK5 signalling pathway. Therefore, our observations describe a novel target of sorafenib, the ERK5 signalling pathway, and establish new mechanistic insights for the antitumour effect of this multikinase inhibitor.This work was supported by grants from Fundación Leticia Castillejo Castillo, Ministerio de Ciencia, Innovación y Universidades (MCIU), Agencia Estatal de Investigación (AEI) and Fondo Europeo de Desarrollo Regional (FEDER) (RTI2018-094093-B-I00) to RSP and MJRH.

Mirroring Opposition Threats

Hugo Chávez and his Bolivarian Movement came to power in 1999 promising to refound the Venezuelan state and restructure the polity in ways that would build “popular power” through the promotion of grassroots participation, organization, and mobilization. Once in office, the Bolivarian forces launched a series of initiatives to sponsor organization and mobilization among supporters, which ranged widely in their functions and strategic purpose. State-mobilized organizations can be seen as operating in three different arenas of politics: the local governance arena; the electoral arena; and the protest arena. From an ideological standpoint, the Bolivarian Movement was oriented toward sponsoring organizations that could operate in the first of these arenas, helping realize Chávez’s vision of constructing a “protagonistic democracy” by establishing vehicles for citizen participation in local governance. In the terminology of this volume, these activities are best seen as a form of “infrastructural mobilization,” working to solidify political support and achieve the government’s longer-term aims

Seguimiento de las guías españolas para el manejo del asma por el médico de atención primaria: un estudio observacional ambispectivo

Objetivo Evaluar el grado de seguimiento de las recomendaciones de las versiones de la Guía española para el manejo del asma (GEMA 2009 y 2015) y su repercusión en el control de la enfermedad. Material y métodos Estudio observacional y ambispectivo realizado entre septiembre del 2015 y abril del 2016, en el que participaron 314 médicos de atención primaria y 2.864 pacientes. Resultados Utilizando datos retrospectivos, 81 de los 314 médicos (25, 8% [IC del 95%, 21, 3 a 30, 9]) comunicaron seguir las recomendaciones de la GEMA 2009. Al inicio del estudio, 88 de los 314 médicos (28, 0% [IC del 95%, 23, 4 a 33, 2]) seguían las recomendaciones de la GEMA 2015. El tener un asma mal controlada (OR 0, 19, IC del 95%, 0, 13 a 0, 28) y presentar un asma persistente grave al inicio del estudio (OR 0, 20, IC del 95%, 0, 12 a 0, 34) se asociaron negativamente con tener un asma bien controlada al final del seguimiento. Por el contrario, el seguimiento de las recomendaciones de la GEMA 2015 se asoció de manera positiva con una mayor posibilidad de que el paciente tuviera un asma bien controlada al final del periodo de seguimiento (OR 1, 70, IC del 95%, 1, 40 a 2, 06). Conclusiones El escaso seguimiento de las guías clínicas para el manejo del asma constituye un problema común entre los médicos de atención primaria. Un seguimiento de estas guías se asocia con un control mejor del asma. Existe la necesidad de actuaciones que puedan mejorar el seguimiento por parte de los médicos de atención primaria de las guías para el manejo del asma. Objective: To assess the degree of compliance with the recommendations of the 2009 and 2015 versions of the Spanish guidelines for managing asthma (Guía Española para el Manejo del Asma [GEMA]) and the effect of this compliance on controlling the disease. Material and methods: We conducted an observational ambispective study between September 2015 and April 2016 in which 314 primary care physicians and 2864 patients participated. Results: Using retrospective data, we found that 81 of the 314 physicians (25.8%; 95% CI 21.3–30.9) stated that they complied with the GEMA2009 recommendations. At the start of the study, 88 of the 314 physicians (28.0%; 95% CI 23.4–33.2) complied with the GEMA2015 recommendations. Poorly controlled asthma (OR, 0.19; 95% CI 0.13–0.28) and persistent severe asthma at the start of the study (OR, 0.20; 95% CI 0.12–0.34) were negatively associated with having well-controlled asthma by the end of the follow-up. In contrast, compliance with the GEMA2015 recommendations was positively associated with a greater likelihood that the patient would have well-controlled asthma by the end of the follow-up (OR, 1.70; 95% CI 1.40–2.06). Conclusions: Low compliance with the clinical guidelines for managing asthma is a common problem among primary care physicians. Compliance with these guidelines is associated with better asthma control. Actions need to be taken to improve primary care physician compliance with the asthma management guidelines

Arconada expone su visión sobrelo que considera la confrontación mundial sobre el agua entrelos intereses trasnacionales orientados a la mercantilización de eserecurso y los movimientos que luchan por declararlo bien público yderecho humano fundamental para la humanidad

Seis años después: mesas técnicas y consejos comunitarios de aguas (Aportes para un balance de la experiencia desarrollada)

El autor define las Mesas Técnicas de Agua como la respuesta organizada de la comunidad a cualquier problema o carencia en lo que al servicio de agua potable y saneamiento se refiere y explica que los Consejos Comunitarios de Aguas son la reunión que agrupa a las comunidades que comparten un determinado sistema hidráulico. Impulsados por el gobierno de Chávez desde el primer año de la administración, estos instrumentos de participación comunitaria ya llevan seis años en funcionamiento y el artículo tiene como propósito narrar la experiencia acumulada, señalando los logros y los desaciertos de su implementación
