Tratamiento de las fracturas acetabulares mediante artroplastia de cadera primaria

1. Introducción y objetivos: El tratamiento de las fracturas acetabulares constituye siempre un desafío para el cirujano ortopédico, siendo muy frecuentes los fracasos que obligan a una artroplastia total de cadera (ATC) secundaria, suponiendo un especial problema en el paciente de edad avanzada. Una buena alternativa puede ser la artroplastia total de cadera en la fase aguda de la fractura. El objetivo de este estudio es exponer los resultados de los pacientes que fueron tratados mediante esta técnica en nuestro servicio. 2. Material y métodos: Se trata de un estudio retrospectivo en el que se revisaron un total de 11 pacientes tratados mediante artroplastia de cadera con vástago cementado, cotilo cementado sobre anillo de Burch Schneider y autoinjerto en el fondo de cotilo obtenido de la cabeza resecada. Un paciente falleció en el postoperatorio inmediato quedando un total de 10 pacientes (7 varones), con una edad media de 66,6 años (47-83). El mecanismo lesional fue de alta energía en 4 casos, y de baja energía en los 6 restantes. Se recogieron: datos demográficos, quirúrgicos, complicaciones y resultados funcionales y radiológicos. 3. Resultados: El tiempo de demora quirúrgica fue de 21,1 días (11-36), ya que la bibliografía demuestra que demorando la cirugía disminuye el sangrado, y el tiempo medio de hospitalización de 39,5 días (24-87). Durante el postoperatorio inmediato hubo dos pacientes que presentaron una infección aguda, y uno con afectación motora del ciático poplíteo externo (CPE). El tiempo de seguimiento medio fue de 23,4 meses (6-36). El Harris Hip Score final fue de 82 puntos de media y el Merle D’Aubigné score de 15/18. En 5 pacientes aparecieron calcificaciones heterotópicas sin repercusión funcional, y no hubo signos de aflojamiento en ninguno de ellos. 4. Conclusiones: Clásicamente los pacientes con fractura de acetábulo han sido tratados de forma conservadora con pobres resultados, por lo que se han intentado buscar nuevas alternativas. El tratamiento de elección actualmente, suele ser la osteosíntesis, sin embargo, los resultados funcionales a largo plazo no son muy prometedores, con una alta tasa de reconversión a ATC tardía, que no está exenta de complicaciones. Consideramos la ATC en fase aguda con un anillo de Burch Schneider e injerto óseo una alternativa segura para las fracturas acetabulares desplazadas, con una baja mortalidad y unos buenos resultados funcionales. Nuestros resultados son comparables con otros estudios en la literatura. <br /

Effective Disclosure in the Fast-Fashion Industry: from Sustainability Reporting to Action

[Abstract]: This work, set in the context of the apparel industry, proposes an action-oriented disclosure tool to help solve the sustainability challenges of complex fast-fashion supply chains (SCs). In a search for effective disclosure, it focusses on actions towards sustainability instead of the measurements and indicators of its impacts. We applied qualitative and quantitative content analysis to the sustainability reporting of the world’s two largest fast-fashion companies in three phases. First, we searched for the challenges that the organisations report they are currently facing. Second, we introduced the United Nations’ Sustainable Development Goals (SDGs) framework to overcome the voluntary reporting drawback of ‘choosing what to disclose’, and revealed orphan issues. This broadened the scope from internal corporate challenges to issues impacting the ecosystems in which companies operate. Third, we analysed the reported sustainability actions and decomposed them into topics, instruments, and actors. The results showed that fast-fashion reporting has a broadly developed analysis base, but lacks action orientation. This has led us to propose the ‘Fast-Fashion Sustainability Scorecard’ as a universal disclosure framework that shifts the focus from (i) reporting towards action; (ii) financial performance towards sustainable value creation; and (iii) corporate boundaries towards value creation for the broader SC ecosystem

ARTROPLASTIA TOTAL DE CADERA CON VÁSTAGO CORTO. ESTUDIO A CORTO PLAZO.

La artroplastia total de cadera conlleva el recambio total de la articulación de la cadera por componentes mecánicos. En sus inicios se planteaba como último recurso en pacientes con artrosis avanzada. Sin embargo, sus buenos resultados, la evolución en la técnica quirúrgica y la evolución de los componentes, hace que cada vez se implanten más artroplastias de cadera en población joven con una vida activa. En base a esto, se empezaron a implantar los vástagos cortos en artroplastia total de cadera en pacientes jóvenes. La ventaja principal es que los vástagos cortos requieren de una menor resección ósea, lo que facilita su recambio si surgiera la necesidad, ya que las prótesis de cadera tienen una duración limitada. El objetivo de este estudio es exponer los resultados de los pacientes intervenidos de artroplastia total de cadera con vástago corto en el Hospital Clínico Universitario Lozano Blesa. <br /

La gestión del ciclo del agua a través de una investigaciónacción participada. El caso de las Hortes de Baix

[EN] This experience aims to recover a space of historical irrigated gardens located in the metropolitan area of Barcelona, Spain. From understanding the traditional water management as cultural heritage, the project has a double goal: on the one hand, to promote sustainable urban design and, on the other hand, to boost a new community consciousness connected to the territory. Through several phases, the project solves a double environmental conflict linked to the irrigation system: on one side, the lack of enough water availability and, on the other side, the health risk due to the spill of urban polluted waters in the main irrigation canal of this space. Consequently, the main proposal is based on the gathering of thermal clean water surplus of spas and public washing places -that are not reused in the gardens presently- to provide enough quality water for the irrigation. By means of an action-research process it’s possible to recover the active ability of urban citizens as producer agents, as well as the quotidian practices related to water self-management as the imaginary of place identity, that is to say, the intangible heritage of the water management as a reference model towards the sustainability.[ES] Esta experiencia trata de recuperar un espacio de huertas de regadío históricas situadas en la región metropolitana de Barcelona. Partiendo de comprender la gestión tradicional del agua como patrimonio, el proyecto tiene un doble objetivo: por un lado, promueve el diseño urbano sostenible y, por el otro, favorece una nueva consciencia comunitaria sobre el territorio. Las distintas fases tienen la misión de resolver un doble conflicto ambiental relacionado con las aguas de riego: por un lado por la falta de disponibilidad de agua suficiente, y por el otro por el riesgo sanitario que suponen los vertidos contaminantes de aguas negras del centro urbano a la acequia principal de este espacio. Consecuentemente la principal propuesta se basa en la captación de las diversas fuentes de agua limpia termal sobrante de balnearios y lavaderos que no se reutilizan en las huertas actualmente y que permitirán un abastecimiento de agua de riego suficiente y de buena calidad. Mediante un proceso de investigación-acción es posible recuperar la capacidad activa del ciudadano urbano como agente productor, las prácticas cotidianas asociadas con la autogestión del agua como imaginario identitario del lugar, es decir, el patrimonio intangible de la gestión del agua como modelo de referencia hacia la sostenibilidad.Albareda Fernández, E.; Serra Permanyer, M.

Mortality increase after hip fracture in aged patients during the first 6 months of the covid-19 epidemic

Background: The COVID-19 pandemic modified hospital functioning, social mobility and assistance to the elderly. These factors may alter hip fracture evolution. Methods: Retrospective study of patients > 65 years suffering hip fracture fromthe 1st of March to the 31st of August of 2020, and compared with patients from the same period of 2019; 199 patients from 2019 (79.4%women) (mean age: 84.9 ± 7.72 years), and 203 patients from 2020 (69.5%women) (mean age: 85.37 ± 8.13 years). Extracapsular fractures were 57.3% in 2019, and 58.6% in 2020. Follow-up was made until death or 6 months after surgery. Results: In 2019, 44 patients (22.1%) died in the six postoperative months, and 61 patients (30%) in 2020 (OR 1.513; 95% CI 0.96–2.37; p = 0.199). There were no significant differences in mortality during postfracture hospitalization (11.1% in 2019; 11.82% in 2020) and in the first postoperative month (16.6% in 2019; 22.66% in 2020). Four patients died during hip fracture hospitalization over 8 patients presenting PCR+. In 30 patients SARS-CoV-2 infection was diagnosed during the six months after hip fracture in 13 patients thiswas the cause of death (21.3% of causes). Dementiawas associated with high mortality in patients with a SARS-CoV-2 diagnosis (6 out of 13 patients died with SARS-CoV-2 infection and dementia). Conclusions: An increase in the 6 postoperative months mortality in 2020 compared with the same period in 2019 was observed. An important cause of death was SARS-CoV-2 infection

Smart-working VS office work: how does personal exposure to different air pollutants change?

The COVID-19 pandemic is raging all over the world, with possible structural effects on the work: the smart-working (WFH -Working From Home) role is therefore emphasized by the fact that it could become a traditional way of working in many work sectors. Several scientific papers have recently analyzed the WFH phenomenon under different aspects, but scientific studies have not yet been conducted considering the differences between WFH and WFO (Working From Office), in terms of evaluation of personal exposure assessment to selected airborne pollutants. This study, therefore, aims to evaluate, using portable monitors, the differences in terms of personal exposure to selected airborne pollutants, during different working conditions (WFO vs WFH), over long periods of time (from days to weeks), extending the results to even longer periods (years), to adhere to the approach proposed by the concept of the exposome. The preliminary results of this study refer to three separate phases of the work (i) re-analyses of literature data via Monte Carlo simulation, and assessment of personal exposure to different air pollutants during different working conditions, during (ii) “long term” campaign and (iii) a “short term” monitoring campaign. During the two different measurement campaigns, portable instrumentation was used, because of the ability of these kinds of instruments to obtain data characterized by a high spatial and temperature resolution. The re-elaborations of the data obtained from the literature show how, under different conditions, the exposure concentrations to different PM fractions are statistically lower in WFH working conditions, compared to WFO conditions. These results are in contrast with the preliminary results obtained from exploratory monitoring (both for the “long term” and for the “short term” campaigns). The results obtained from these exploratory monitoring show that the WFH condition has a greater impact on the daily exposure of the monitored subjects, compared to the WFO condition

Differential roles of HypC and HupF proteins for hydrogenase synthesis in Rhizobium leguminosarum.

Some diazotrophic bacteria induce [NiFe] hydrogenases to recycle the hydrogen evolved by nitrogenase during the nitrogen fixation process. Biosynthesis of Rhizobium leguminosarum [FeNi] hydrogenase requires a number of accessory proteins (products of hup and hyp genes) that mediate the incorporation of Ni and Fe into the active site. Among them, HypC-paralog HupF and HupK are present in bacteria that synthesize hydrogenase in the presence of oxygen. Hydrogenase activity in mutant strains lacking either hupF or hypC genes was severely reduced, indicating that both proteins are essentials for biosynthesis of hydrogenase. Co-purification of StrepTag labelled variants of HupF and HypC by an affinity chromatography-based approach demonstrated interactions between HupL-HupF and HypC-HupK. Experiments carried out with strains induced for hydrogenase under 3% oxygen tensions indicated that HupF might provide additional stability to HupL under these condition
