    El presente estudio analiza las variables que explican el desempeño del equipo de fútbol de un país dentro de ciertas copas del mundo. Las variables se clasifican en tres grupos: macroeconómicas, demográficas y cultural-deportivas. Encontramos que tanto las variables macroeconómicas y demográficas no son significativas para explicar el rendimiento de una Nación, pero la que llamamos variable cultural-deportiva sí es una variable relevante para el estudio de eficiencia de un equipo de futbol.El resultado contrasta con estudios previos, los que no consideran la medición del rendimiento de cada participante con nuestra técnica. El ranking del equipo participante se evalúa mediante la técnica de Data Envelopment Analysis (DEA, por sus siglas en Inglés) para obtener las puntuaciones de eficiencia basadas en la idea de la maximización de puntos dados los intentos de anotar por tiros de esquina, fuera del área, y en el arco. Este estudio es relevante para evaluar el rendimiento en el fútbol como una función de variables de control social como ser anfitrión o afiliado a una federación

    Energy prices and competitiveness in Latin American emerging economies

    This paper presents an evaluation of the impact of international oil prices on the competitiveness of three emergent economies in Latin America. We use the methodology of input-output tables for: Peru, Chile and Colombia. Recent outstanding macroeconomic performance of these three emergent countries caused an increase in their demand for energy, which deepened their trade deficit of oil. The effects of high petroleum prices are divided into (a) the impact on costs of new energy prices and (b) the impact on competitiveness. The main conclusion is that energy inputs today constitute the most important cost for industries in Peru, Chile, and Colombia. We recommend some policies for energy efficiency that are consistent with the competitiveness of these three emerging market economies

    The following paper analyses the sustainability of the Peruvian “Pay as You Go System” which is provided by the Government. In Peru, the “Pay as you Go System” coexists with Private Pension Funds or “Fully Funded Pension”. Sometimes both systems compete with each other with advantages and disadvantages between them. We found that “Pay as You Go System” cannot be sustainable over a long period of time. In addition, based on a comparative analysis of advantages and disadvantages, we propose some recommendations to make Private Pension Funds (Fully Funded Pension) the best alternative to Pay as You Go System.Este trabajo analiza la sostenibilidad del sistema pensional colectivo implementado por el gobierno peruano. En Perú, este sistema coexiste con el de fondos privados de pensiones o fondo individual. En algunos casos, estos dos sistemas compiten entre sí, con sus ventajas y desventajas entre ambos sistemas. Según nuestros hallazgos, el sistema pensional de reparto colectivo de pensiones no es sostenible en un largo plazo. Asimismo, sobre la base de un análisis comparativo de las ventajas y desventajas entre ambos sistemas, se formulan algunas recomendaciones para que los fondos privados de pensión (Sistema Individual) se conviertan en la mejor alternativa al sistema pen­sional colectivo

    Ongrowing European fish species with feeds formulated with a by-product derived from cereal processing

    Trabajo presentado en el congreso Aquaculture Europe 2023: Balanced Diversity in Aquaculture Development celebrado en Viena (Austria) entre el 18 y el 21 de septiembre de 2023.The cereal industry generates large amounts of residual by-products with high potential as feed ingredient for aquafeeds. Such raw materials could help to substitute protein and lipids from less sustainable sources such as soy concentrate, wheat flour or oils and reduce the competitiveness between the production of aquafeeds and the use of food for human consumption. In this study, one of these by-products, corn gluten feed, has been tested in dose-response experiments as ingredients in on-growing feeds for two European species (greater amberjack, Seriola dumerili; gilthead seabream, Sparus aurata). The final aim was to examine to what extent this more-sustainable and low-cost product can be used as alternate ingredient for fish feeds.Project SUSTAINFEED, EIT Food 21168, Co-funded by the European Union

    Metabolic and Functional Profile of Premenopausal Women With Metabolic Syndrome After Training With Elastics as Compared to Free Weights

    Get PDF
    The aim of this study was to compare the effects of a strength training program (STP) using free weights (FW) versus elastic tubing (ET) in 62 premenopausal, sedentary women diagnosed with metabolic syndrome (MS). Participants were randomly assigned to the FW or ET experimental group (EG) or a control group whose members remained sedentary. Members of each EG followed their assigned STP for 12 weeks, and biomarkers (BMs) related to MS and motor function (MF) parameters were evaluated. Both EGs showed a significant reduction in C-reactive protein level and a positive trend in the other BMs. Almost all MF parameters increased significantly in both EGs. No positive changes were found in the CG. These results indicate that the implementation of an STP, with either FW or ET, improves both metabolic health and MF and should be considered part of the basic approach to health care in women

    Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

    The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

    Time to Switch to Second-line Antiretroviral Therapy in Children With Human Immunodeficiency Virus in Europe and Thailand.

    Background: Data on durability of first-line antiretroviral therapy (ART) in children with human immunodeficiency virus (HIV) are limited. We assessed time to switch to second-line therapy in 16 European countries and Thailand. Methods: Children aged <18 years initiating combination ART (≥2 nucleoside reverse transcriptase inhibitors [NRTIs] plus nonnucleoside reverse transcriptase inhibitor [NNRTI] or boosted protease inhibitor [PI]) were included. Switch to second-line was defined as (i) change across drug class (PI to NNRTI or vice versa) or within PI class plus change of ≥1 NRTI; (ii) change from single to dual PI; or (iii) addition of a new drug class. Cumulative incidence of switch was calculated with death and loss to follow-up as competing risks. Results: Of 3668 children included, median age at ART initiation was 6.1 (interquartile range (IQR), 1.7-10.5) years. Initial regimens were 32% PI based, 34% nevirapine (NVP) based, and 33% efavirenz based. Median duration of follow-up was 5.4 (IQR, 2.9-8.3) years. Cumulative incidence of switch at 5 years was 21% (95% confidence interval, 20%-23%), with significant regional variations. Median time to switch was 30 (IQR, 16-58) months; two-thirds of switches were related to treatment failure. In multivariable analysis, older age, severe immunosuppression and higher viral load (VL) at ART start, and NVP-based initial regimens were associated with increased risk of switch. Conclusions: One in 5 children switched to a second-line regimen by 5 years of ART, with two-thirds failure related. Advanced HIV, older age, and NVP-based regimens were associated with increased risk of switch

    Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
