Plastia sustitutiva del LCA con tendones de la pata de ganso cuadruples

Se han estudiado retrospectivamente 44 casos de pacientes a los que se les realizó por vía artrocóspica una plastia sustitutiva intraticular de reconstrucción del LCA, con tendones de Semitendinoso y Recto Interno antólogos, en 4 fascículos. La edad media de los pacientes fue de 25 años. Los resultados a corto plazo (2 años) obtenidos con KT-1000 a 30 Ib han sido excelente-bueno en 40 casos y aceptable en 4 casos. Cuatro casos referían sensación de inestabilidad. Los test de Lachman y Pívot-Shift fueron positivos en 3 casos. Con el test de Lysholm se obtuvo resultado excelente-bueno en 36 casos, regular en 6 y malo en 2 casos. Este tipo de plastia presenta una baja morbilidad de la zona dadora del injerto, comparativamente con la plastia HTH patelar antóloga, y sin alteración del aparato extensor.A retrospective study of 44 patients, who underwent an arthroscopically assisted ACL (anterior cruciata ligament) reconstruction with quadrupled semitendinosus/gracilis tendon autografts was performed. The mean age was 25 years. Short term outcomes of knee stability (2 years follow-up) with KT-1000 arthrometer at 30 pounds were excellent or good in 40 cases and acceptable in 4. Pain or joint swelling were not found. Instability complaints were found in 4 cases. Lachman and Pivot-shift were found positive in 3 cases. Lysholm questionnaire scores were excellent or good in 36 cases, fair in 6 cases and per in two cases, the donor site morbidity associated with hamstring harvest seems to be minimal compared with bonepatellar tendon-bone autograft without impairment of the extensor mechanism

Tratamiento de las fracturas complejas de fémur mediante enclavado intramedular encerrojado de Brooker-Wills

Se realiza un estudio retrospectivo de 19 pacientes con fracturas complejas de fé- mur tratados mediante el clavo bloqueado de Brooker-Wills. La causa más frecuente de dichas fracturas fueron los accidentes de tráfico. Hubo lesiones asociadas en el 63% de los casos. El tiempo medio de seguimiento fue de 27 meses. Nuestros resultados han sido evaluados mediante los criteros de Thorensen, obteniendo un 84% de resultados favorables. Hubo problemas técnicos intraoperatorios en 8 pacientes, la mayoría debidos a la penetración de la cortical femoral distal por una de las aletas. Todas las fracturas consolidaron. La mayor ventaja de este clavo la encontramos en la sencillez del bloqueo distal, lo cual supone una menor exposición a la radiación y un acortamiento del tiempo quirúrgico.A retrospective study of 19 patients with complex fermoral fractures treated with the Brooker-Wills interlocking intramedullary nail is reported. The traffic-accident was the most common cause of these fractures. Associated injuries were found in 63% of cases. The mean time follow-up period was 27 months. Results were assessed according to Thorensen's criteria. We found excellent or good results in 84% of these patients. There were intraoperative technical problems without clinical complications in 8 patients, most of them due to distal femoral cortex penetration with the pins. Union occurred in all fractures. The greatest advantage of this nail comes from the easy insertion of distal pins, providings less exposition to radiation and a shorter operative tim

Basketball game-related statistics that discriminate between teams season-long success

The aim of the present study was to identify the game-related statistics that discriminate between season-long successful and unsuccessful basketball teams participating in the Spanish Basketball League (LEB1). The sample included all 145 average records per season from the 870 games played between the 2000-2001 and the 2005-2006 regular seasons. The following game-related statistics were gathered from the official box scores of the Spanish Basketball Federation: 2- and 3-point field-goal attempts (both successful and unsuccessful), free-throws (both successful and unsuccessful), defensive and offensive rebounds, assists, steals, turnovers, blocks (both made and received), and fouls (both committed and received). To control for season variability, all results were normalized to minutes played each season and then converted to z-scores. The results allowed discrimination between best and worst teams' performances through the following game-related statistics: assists (SC=0.47), steals (SC=0.34), and blocks (SC=0.30). The function obtained correctly classified 82.4% of the cases. In conclusion, season-long performance may be supported by players' and teams' passing skills and defensive preparation

New solar axion search in CAST with 4^4He filling

The CERN Axion Solar Telescope (CAST) searches for $a\to\gamma$ conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward the Sun. Two parallel magnet bores can be filled with helium of adjustable pressure to match the X-ray refractive mass $m_\gamma$ to the axion search mass $m_a$. After the vacuum phase (2003--2004), which is optimal for $m_a\lesssim0.02$ eV, we used $^4$He in 2005--2007 to cover the mass range of 0.02--0.39 eV and $^3$He in 2009--2011 to scan from 0.39--1.17 eV. After improving the detectors and shielding, we returned to $^4$He in 2012 to investigate a narrow $m_a$ range around 0.2 eV ("candidate setting" of our earlier search) and 0.39--0.42 eV, the upper axion mass range reachable with $^4$He, to "cross the axion line" for the KSVZ model. We have improved the limit on the axion-photon coupling to $g_{a\gamma}< 1.47\times10^{-10} {\rm GeV}^{-1}$ (95% C.L.), depending on the pressure settings. Since 2013, we have returned to vacuum and aim for a significant increase in sensitivity.Comment: CAST Collaboration 6 pages 3 figure

Moving towards public policy-ready science: philosophical insights on the social-ecological systems perspective for conservation science

The social-ecological systems (SES) perspective stems from the need to rethink the ways humans relate to the environment, given the evidence that conventional conservation and management approaches are often ineffective in dealing with complex socio-environmental problems. The SES approach conceives non-scientific and scientific knowledge as equally necessary in the process of management and public policy formation. Thus, the adoption of the SES approach must also serve to make better decisions about what kind of science and technology would be ‘public policy-ready’ (as well as also ‘policy-relevant’); that is, a science oriented and conceived to provide concrete solutions to societal needs and demands. Here we review and reinterpret the SES perspective as a real paradigm change for conservation science. Under the lenses of philosophy, we try to untangle some weak points of the SES approach in order to advance to a conservation science closer to the process of science-based public policy creation and to enhance the intertwining with other types of knowledge. In this sense, we discuss how co-production of knowledge and decision-making process under the SES perspective are a huge step forward towards fulfilling the need to bring increasingly closer the spheres of science and policy, narrowing its interface.Fil: Sala, Juan Emilio.

Molecular characterisation of protist parasites in human-habituated mountain gorillas (Gorilla beringei beringei), humans and livestock, from Bwindi impenetrable National Park, Uganda

Over 60 % of human emerging infectious diseases are zoonotic, and there is growing evidence of the zooanthroponotic transmission of diseases from humans to livestock and wildlife species, with major implications for public health, economics, and conservation. Zooanthroponoses are of relevance to critically endangered species; amongst these is the mountain gorilla (Gorilla beringei beringei) of Uganda. Here, we assess the occurrence of Cryptosporidium, Cyclospora, Giardia, and Entamoeba infecting mountain gorillas in the Bwindi Impenetrable National Park (BINP), Uganda, using molecular methods. We also assess the occurrence of these parasites in humans and livestock species living in overlapping/adjacent geographical regions

Metabolite and lipoprotein profiles reveal sex-related oxidative stress imbalance in de novo drug-naive Parkinson's disease patients

Parkinson’s disease (PD) is the neurological disorder showing the greatest rise in prevalence from 1990 to 2016. Despite clinical definition criteria and a tremendous effort to develop objective biomarkers, precise diagnosis of PD is still unavailable at early stage. In recent years, an increasing number of studies have used omic methods to unveil the molecular basis of PD, providing a detailed characterization of potentially pathological alterations in various biological specimens. Metabolomics could provide useful insights to deepen our knowledge of PD aetiopathogenesis, to identify signatures that distinguish groups of patients and uncover responsive biomarkers of PD that may be significant in early detection and in tracking the disease progression and drug treatment efficacy. The present work is the first large metabolomic study based on nuclear magnetic resonance (NMR) with an independent validation cohort aiming at the serum characterization of de novo drug-naive PD patients. Here, NMR is applied to sera from large training and independent validation cohorts of German subjects. Multivariate and univariate approaches are used to infer metabolic differences that characterize the metabolite and the lipoprotein profiles of newly diagnosed de novo drug-naive PD patients also in relation to the biological sex of the subjects in the study, evidencing a more pronounced fingerprint of the pathology in male patients. The presence of a validation cohort allowed us to confirm altered levels of acetone and cholesterol in male PD patients. By comparing the metabolites and lipoproteins levels among de novo drug-naive PD patients, age- and sex-matched healthy controls, and a group of advanced PD patients, we detected several descriptors of stronger oxidative stress

Recommendations for ophthalmologic practice during the easing of COVID-19 control measures

In the context of the COVID-19 pandemic, this paper provides recommendations for medical eye care during the easing of control measures after lockdown. The guidelines presented are based on a literature review and consensus among all Spanish Ophthalmology Societies regarding protection measures recommended for the ophthalmologic care of patients with or without confirmed COVID-19 in outpatient, inpatient, emergency and surgery settings. We recommend that all measures be adapted to the circumstances and availability of personal protective equipment at each centre and also highlight the need to periodically update recommendations as we may need to readopt more restrictive measures depending on the local epidemiology of the virus. These guidelines are designed to avoid the transmission of SARS-CoV-2 among both patients and healthcare staff as we gradually return to normal medical practice, to prevent postoperative complications and try to reduce possible deficiencies in the diagnosis, treatment and follow-up of the ophthalmic diseases. With this update (5th) the Spanish Society of Ophthalmology is placed as one of the major ophthalmology societies providing periodic and systematized recommendations for ophthalmic care during the COVID-19 pandemic

Measurement of the dijet invariant mass cross section in proton anti-proton collisions at sqrt{s} = 1.96 TeV

The inclusive dijet production double differential cross section as a function of the dijet invariant mass and of the largest absolute rapidity of the two jets with the largest transverse momentum in an event is measured in proton anti-proton collisions at sqrt{s} = 1.96 TeV using 0.7 fb^{-1} integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider. The measurement is performed in six rapidity regions up to a maximum rapidity of 2.4. Next-to-leading order perturbative QCD predictions are found to be in agreement with the data.Comment: Published in Phys. Lett. B, 693, (2010), 531-538, 8 pages, 2 figures, 6 table
