    Los riesgos en la actualidad son una parte fundamental que toda institución debe evaluar, por lo cual surge la presente investigación como respuesta a la necesidad de implementar un “Modelo de Gestión de Riesgo crediticio para el mejoramiento de la Administración de los Microcréditos de la Cooperativa ACOACAC de R.L” El objetivo de este estudio es el de facilitar la comprensión y aplicación de un diseño de gestión de riesgo de crédito a través de análisis de los estados financieros, proporcionando así una herramienta práctica y sencilla que permita a la cooperativa implementar procedimientos adecuados para identificar, medir, controlar, mitigar, monitorear y comunicar los riesgos de los Microcréditos asociados con la cooperativa , los cuales al ser ejecutados correctamente ayudarán a encontrar soluciones reales y prácticas. Con los resultados obtenidos por medio de la encuesta, la entrevista y la observación se lograron determinar que la Cooperativa ACOACAC de R.L no cuenta con los conocimientos necesarios para implementar un modelo de gestión de riesgo crediticio, y que para llevarlo a cabo se requiere establecer políticas y procedimientos adecuados a las actividades que se realizan. Es por ello que se establecen los elementos con los que cuenta la Cooperativa así como los que requiere y necesita tener ya que con ello se valorará el riesgo, los procedimientos para la implementación de dicho modelo a la hora de promover un microcrédito. Además de ello se determinará el impacto y la probabilidad en el cual un riesgo pueda tener incidencia negativa o positiva dentro de la cooperativa y con ello poder clasificar el tipo de riesgos y así poder identificarlo y medirlo. Así mismo se elaborará una matriz de riesgo o mapa de calor el cual mostrará el riesgo más vulnerable y con ello poder establecer diferentes estrategias entre ellos, los límites de otorgamiento, consideración de garantías, monitoreo y gestiones que se pueden implementar para la recuperación de los microcréditos así como la implementación de políticas. La Cooperativa ACOACAC de R.L tiene como actividad económica principal la captación y colocación de fondos en diferentes tipos de crédito a la población a fin de contribuir con el mejoramiento económico así como la satisfacción de necesidades crediticias. Es por ello que se cuenta con los siguientes elementos: a) Misión Somos una Asociación Cooperativa, de solidó prestigio dedicada a la prestación de servicios financieros de ahorro y crédito de forma inmediata, transparente y oportuna, mediante la amabilidad, responsabilidad y experiencia del personal; con la finalidad de impulsar el desarrollo económico y social de sus asociados (as) en toda la Zona Oriental. b) Visión Ser una Asociación Cooperativa, de expansión sólida en toda la Zona Oriental, en la prestación de servicios diversificados; ahorro, crédito, remesas familiares y servicios de pago de energía eléctrica, etc. Mediante la eficiencia y eficacia del personal operativo y administrativo. c) Estructura Organizativa La Cooperativa ACOACAC de R.L no cuenta con una estructura organizativa, en la cual se requiera un ordenamiento jerárquico que especifique la función que cada uno debe ejecuta

    Background: The contribution of the virus to the pathogenesis of severe COVID-19 is still unclear. We aimed to evaluate associations between viral RNA load in plasma and host response, complications, and deaths in critically ill patients with COVID-19. Methods: We did a prospective cohort study across 23 hospitals in Spain. We included patients aged 18 years or older with laboratory-confirmed SARS-CoV-2 infection who were admitted to an intensive care unit between March 16, 2020, and Feb 27, 2021. RNA of the SARS-CoV-2 nucleocapsid region 1 (N1) was quantified in plasma samples collected from patients in the first 48 h following admission, using digital PCR. Patients were grouped on the basis of N1 quantity: VIR-N1-Zero ([removed]2747 N1 copies per mL). The primary outcome was all-cause death within 90 days after admission. We evaluated odds ratios (ORs) for the primary outcome between groups using a logistic regression analysis. Findings: 1068 patients met the inclusion criteria, of whom 117 had insufficient plasma samples and 115 had key information missing. 836 patients were included in the analysis, of whom 403 (48%) were in the VIR-N1-Low group, 283 (34%) were in the VIR-N1-Storm group, and 150 (18%) were in the VIR-N1-Zero group. Overall, patients in the VIR-N1-Storm group had the most severe disease: 266 (94%) of 283 patients received invasive mechanical ventilation (IMV), 116 (41%) developed acute kidney injury, 180 (65%) had secondary infections, and 148 (52%) died within 90 days. Patients in the VIR-N1-Zero group had the least severe disease: 81 (54%) of 150 received IMV, 34 (23%) developed acute kidney injury, 47 (32%) had secondary infections, and 26 (17%) died within 90 days (OR for death 0·30, 95% CI 0·16–0·55; p<0·0001, compared with the VIR-N1-Storm group). 106 (26%) of 403 patients in the VIR-N1-Low group died within 90 days (OR for death 0·39, 95% CI 0·26–0·57; p[removed]11 página

    Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

    Background Acute respiratory distress syndrome (ARDS) can be classified into sub-phenotypes according to different inflammatory/clinical status. Prognostic enrichment was achieved by grouping patients into hypoinflammatory or hyperinflammatory sub-phenotypes, even though the time of analysis may change the classification according to treatment response or disease evolution. We aimed to evaluate when patients can be clustered in more than 1 group, and how they may change the clustering of patients using data of baseline or day 3, and the prognosis of patients according to their evolution by changing or not the cluster.Methods Multicenter, observational prospective, and retrospective study of patients admitted due to ARDS related to COVID-19 infection in Spain. Patients were grouped according to a clustering mixed-type data algorithm (k-prototypes) using continuous and categorical readily available variables at baseline and day 3.Results Of 6205 patients, 3743 (60%) were included in the study. According to silhouette analysis, patients were grouped in two clusters. At baseline, 1402 (37%) patients were included in cluster 1 and 2341(63%) in cluster 2. On day 3, 1557(42%) patients were included in cluster 1 and 2086 (57%) in cluster 2. The patients included in cluster 2 were older and more frequently hypertensive and had a higher prevalence of shock, organ dysfunction, inflammatory biomarkers, and worst respiratory indexes at both time points. The 90-day mortality was higher in cluster 2 at both clustering processes (43.8% [n = 1025] versus 27.3% [n = 383] at baseline, and 49% [n = 1023] versus 20.6% [n = 321] on day 3). Four hundred and fifty-eight (33%) patients clustered in the first group were clustered in the second group on day 3. In contrast, 638 (27%) patients clustered in the second group were clustered in the first group on day 3.Conclusions During the first days, patients can be clustered into two groups and the process of clustering patients may change as they continue to evolve. This means that despite a vast majority of patients remaining in the same cluster, a minority reaching 33% of patients analyzed may be re-categorized into different clusters based on their progress. Such changes can significantly impact their prognosis

    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
