Adaptación a los nuevos Grados de las metodologías docentes empleadas en una asignatura de Estadística Económico-Empresarial

Durante el presente curso 2009/2010 la Universidad Pablo de Olavide (UPO), de Sevilla, ha puesto en marcha el nuevo mapa de titulaciones adaptado al Espacio Europeo de Educación Superior (EEES), el cual está compuesto por 16 grados y 6 dobles grados. Hasta llegar a este punto la UPO trabajó duro durante más de 6 años en la adaptación de su docencia al nuevo marco establecido por dicho EEES. Con tal objetivo, se puso en marcha en la Facultad de Empresariales, entre otras, una Experiencia Piloto de implantación del sistema de créditos europeos pretendiendo, fundamentalmente, renovar la metodología docente, incrementar la calidad de la docencia y de hacerla más cercana al alumno, siempre atendiendo a los planes de estudio actualmente vigentes. En el presente trabajo mostramos la adaptación que se realizó en la asignatura de Estadística e Introducción a la Econometría de la extinta Licenciatura en Administración y Dirección de Empresas en el marco de la Experiencia Piloto y los cambios que se acometieron posteriormente para su implantación en el nuevo Grado en Administración y Dirección de Empresas bajo el nombre: Estadística Empresarial I. Haremos hincapié en aquellos aspectos más destacados relativos al nuevo sistema de evaluación basado en evaluación continua.Artículo revisado por pare

Characteristics and outcomes of multisystem inflammatory syndrome in children: A multicenter, retrospective, observational cohort study in Mexico

IntroductionMultisystem inflammatory syndrome in children associated with coronavirus disease 2019 (MIS-C), a novel hyperinflammatory condition secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is associated with severe outcomes such as coronary artery aneurysm and death.MethodsThis multicenter, retrospective, observational cohort study including eight centers in Mexico, aimed to describe the clinical characteristics and outcomes of patients with MIS-C. Patient data were evaluated using latent class analysis (LCA) to categorize patients into three phenotypes: toxic shock syndrome-like (TSSL)-MIS-C, Kawasaki disease-like (KDL)-MIS-C, and nonspecific MIS-C (NS-MIS-C). Risk factors for adverse outcomes were estimated using multilevel mixed-effects logistic regression.ResultsThe study included 239 patients with MIS-C, including 61 (26%), 70 (29%), and 108 (45%) patients in the TSSL-MIS-C, KDL-MIS-C, and NS-MIS-C groups, respectively. Fifty-four percent of the patients were admitted to the intensive care unit, and 42%, 78%, and 41% received intravenous immunoglobulin, systemic glucocorticoids, and anticoagulants, respectively. Coronary artery dilatation and aneurysms were found in 5.7% and 13.2% of the patients in whom coronary artery diameter was measured, respectively. Any cause in-hospital mortality was 5.4%. Hospitalization after ten days of symptoms was associated with coronary artery abnormalities (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.2–2.0). Age ≥10 years (OR: 5.6, 95% CI: 1.4–2.04), severe underlying condition (OR: 9.3, 95% CI: 2.8–31.0), platelet count <150,000 /mm3 (OR: 4.2, 95% CI: 1.2–14.7), international normalized ratio >1.2 (OR: 3.8, 95% CI: 1.05–13.9), and serum ferritin concentration >1,500 mg/dl at admission (OR: 52, 95% CI: 5.9–463) were risk factors for death.DiscussionMortality in patients with MIS-C was higher than reported in other series, probably because of a high rate of cases with serious underlying diseases

Prediction of long-term outcomes of HIV-infected patients developing non-AIDS events using a multistate approach

Outcomes of people living with HIV (PLWH) developing non-AIDS events (NAEs) remain poorly defined. We aimed to classify NAEs according to severity, and to describe clinical outcomes and prognostic factors after NAE occurrence using data from CoRIS, a large Spanish HIV cohort from 2004 to 2013. Prospective multicenter cohort study. Using a multistate approach we estimated 3 transition probabilities: from alive and NAE-free to alive and NAE-experienced ("NAE development"); from alive and NAE-experienced to death ("Death after NAE"); and from alive and NAE-free to death ("Death without NAE"). We analyzed the effect of different covariates, including demographic, immunologic and virologic data, on death or NAE development, based on estimates of hazard ratios (HR). We focused on the transition "Death after NAE". 8,789 PLWH were followed-up until death, cohort censoring or loss to follow-up. 792 first incident NAEs occurred in 9.01% PLWH (incidence rate 28.76; 95% confidence interval [CI], 26.80-30.84, per 1000 patient-years). 112 (14.14%) NAE-experienced PLWH and 240 (2.73%) NAE-free PLWH died. Adjusted HR for the transition "Death after NAE" was 12.1 (95%CI, 4.90-29.89). There was a graded increase in the adjusted HRs for mortality according to NAE severity category: HR (95%CI), 4.02 (2.45-6.57) for intermediate-severity; and 9.85 (5.45-17.81) for serious NAEs compared to low-severity NAEs. Male sex (HR 2.04; 95% CI, 1.11-3.84), ag
