Long-term outcomes of the global tuberculosis and COVID-19 co-infection cohort

Background: Longitudinal cohort data of patients with tuberculosis (TB) and coronavirus disease 2019 (COVID-19) are lacking. In our global study, we describe long-term outcomes of patients affected by TB and COVID-19. Methods: We collected data from 174 centres in 31 countries on all patients affected by COVID-19 and TB between 1 March 2020 and 30 September 2022. Patients were followed-up until cure, death or end of cohort time. All patients had TB and COVID-19; for analysis purposes, deaths were attributed to TB, COVID-19 or both. Survival analysis was performed using Cox proportional risk-regression models, and the log-rank test was used to compare survival and mortality attributed to TB, COVID-19 or both. Results: Overall, 788 patients with COVID-19 and TB (active or sequelae) were recruited from 31 countries, and 10.8% (n=85) died during the observation period. Survival was significantly lower among patients whose death was attributed to TB and COVID-19 versus those dying because of either TB or COVID-19 alone (p<0.001). Significant adjusted risk factors for TB mortality were higher age (hazard ratio (HR) 1.05, 95% CI 1.03-1.07), HIV infection (HR 2.29, 95% CI 1.02-5.16) and invasive ventilation (HR 4.28, 95% CI 2.34-7.83). For COVID-19 mortality, the adjusted risks were higher age (HR 1.03, 95% CI 1.02-1.04), male sex (HR 2.21, 95% CI 1.24-3.91), oxygen requirement (HR 7.93, 95% CI 3.44-18.26) and invasive ventilation (HR 2.19, 95% CI 1.36-3.53). Conclusions: In our global cohort, death was the outcome in >10% of patients with TB and COVID-19. A range of demographic and clinical predictors are associated with adverse outcomes

Política, desarrollo y ciudadanía. Etapa II (PODECI II) 16H276

El Proyecto PODECI II plantea su continuidad como una propuesta de investigación básica y aplicada encaminada a producir conocimiento teórico y metodológico sobre: 1. el funcionamiento del sistema sociopolítico de la Provincia de Misiones, particularmente sobre los modos de hacer política y la dinámica que asumen las disputas por el poder en el nivel local, tanto en los períodos electorales como inter-electorales; 2. los procesos socio demográficos que están en la base de la estructuración territorial y la segregación de los espacios urbanos y 3. temáticas sociales acuciantes como el desarrollo humano sustentable, la salud o el trabajo. Asimismo, desde el PODECI II se acompañará en las etapas de formulación, ejecución y evaluación, experiencias concretas de desarrollo local en distintos municipios apuntando a transferir capacidades mediante la adopción de técnicas participativas; así como, reflexionar críticamente sobre esas experiencias, con el propósito de aportar a la producción de conocimiento. Adicionalmente es prioridad del Programa formar recursos humanos en el nivel de grado y postgrado capacitados para desempeñarse, tanto en el ámbito académico, como en el diseño e implementación de programas de desarrollo local imbuidos de los principios de la economía social, el asociativismo y la búsqueda de una mayor equidad social

Hemolytic-uremic syndrome in Chile: clinical features, evolution and prognostic factors

Background: Hemolytic-uremic syndrome (HUS) is characterized by acute renal failure, microangiopathic hemolytic anemia and thrombocytopenia. Aim: To describe the characteristics of patients with the diagnosis of HUS in Chile, and to identify the most reliable early predictors of morbidity and mortality. Material and methods: The clinical records of patients with HUS aged less than 15 years, attended between January 1990 and December 2003 in 15 hospitals, were reviewed. Demographic, clinical, biochemical, hematological parameters, morbidity and mortality were analyzed. Results: A cohort of 587 patients aged 2 to 8 years, 48% males, was analyzed. Ninety two percent had diarrhea. At the moment of diagnosis, anuria was observed in 39% of the patients, hypertension in 45% and seizures in 17%. Forty two percent required renal replacement therapy (RRT) and peritoneal dialysis was used in the majority of cases (78%). The most frequently isolated etiological agent was Escherichia coli. Mortality rate was 2.9% in the acute phase of the disease and there was a positive correlation between mortality and anuria, seizures, white blood cell count (WCC) >20.000/mm3 and requirements of renal replacement therapy (p <0.05). Twelve percent of patients evolved to chronic renal failure and the risk factors during the acute phase were the need for renal replacement therapy, anuria, WCC >20.000/mm3, seizures and hypertension. Conclusions: The present study emphasizes important clinical and epidemiological aspects of HUS in a Chilean pediatric population

Movimientos sociales en America Latina : perspectivas, tendencias y casos

Este libro aporta tres cuestiones importantes: primero, explora la riqueza y variedad de los movimientos sociales en América Latina; segundo, ilustra la amplia gama de enfoques y perspectivas que existe entre los estudiosos actuales de la protesta latinoamericana; tercero, muestra que el continente tiene su especificidad propia en el estudio de los movimientos sociales, en diálogo con la academia norteamericana y la europea. Sin lugar a dudas, la presente antología resultará de especial interés a todos los pensadores y pensadoras con una visión crítica de la política, la historia y los movimientos sociales latinoamericanos.
