Resumen tomado de la publicaciónPara entender por qué niños y adolescentes ostentan cada día mayor relieve en sus familias, se propone analizar las modalidades interactivas que se establecen en su seno. Se indican dos tipos de núcleos familiares, el hiperprotector, en el que los padres se ponen en lugar de los hijos para compensar su supuesta fragilidad; y el modelo democrático-permisivo, en el que padres e hijos son amigos, desapareciendo la autoridad. Uno y otro modelo determinan también el tipo de relación que la familia establece con su entorno, y en particular con la escuela.CataluñaMadrid (Comunidad Autónoma).

Climate induced effects on livestock population and productivity in the mediterranean area

The ability of livestock to breed, grow, and lactate to their maximal genetic potential, and their capacity to maintain health is affected by climatic features. Climate affects animals both indirectly and directly. Indirect effects include those that climate exerts on grassland and crops, and on water availability. Additionally, climate may also affect survival of pathogens and/or their vectors, which may cause risks for health in animal and human populations. Analysis of meteorological and entomological data indicate that climate has favored invasion of Culicoides imicola into new regions of the Mediterranean basin where it was previously absent. The meteorological complex has not been studied precisely to determine the optimal combination for normal physiological functions and behavioral actions, health, welfare, and maximal performance of livestock. An index for measurements of environmental warmth and its direct effects in livestock is the Temperature Humidity Index (THI). The THI combines values of temperature and humidity an~ has been widely used as a bioclimatic indicator of thermal stress in livestock. Studies carried out within the CIRCE project permitted to characterize the Mediterranean basin in terms of THI and to establish its strong heterogeneity even if most of the area is at risk of heat stress for farm animals during summer. The same studies also indicated that the area will be also subjected to warming and extreme climate events, which may aggravate the consequences of hot weather in livestock. Comprehensive frameworks need to be developed to identify and target adaptation options that are appropriate for specific contexts. (Résumé d'auteur

Extracorporeal membrane oxygenation for severe acute respiratory distress syndrome associated with COVID-19: a retrospective cohort study

International audienceBackgroundPatients with COVID-19 who develop severe acute respiratory distress syndrome (ARDS) can have symptoms that rapidly evolve to profound hypoxaemia and death. The efficacy of extracorporeal membrane oxygenation (ECMO) for patients with severe ARDS in the context of COVID-19 is unclear. We aimed to establish the clinical characteristics and outcomes of patients with respiratory failure and COVID-19 treated with ECMO.MethodsThis retrospective cohort study was done in the Paris–Sorbonne University Hospital Network, comprising five intensive care units (ICUs) and included patients who received ECMO for COVID-19 associated ARDS. Patient demographics and daily pre-ECMO and on-ECMO data and outcomes were collected. Possible outcomes over time were categorised into four different states (states 1–4): on ECMO, in the ICU and weaned off ECMO, alive and out of ICU, or death. Daily probabilities of occupation in each state and of transitions between these states until day 90 post-ECMO onset were estimated with use of a multi-state Cox model stratified for each possible transition. Follow-up was right-censored on July 10, 2020.FindingsFrom March 8 to May 2, 2020, 492 patients with COVID-19 were treated in our ICUs. Complete day-60 follow-up was available for 83 patients (median age 49 [IQR 41–56] years and 61 [73%] men) who received ECMO. Pre-ECMO, 78 (94%) patients had been prone-positioned; their median driving pressure was 18 (IQR 16–21) cm H2O and PaO2/FiO2 was 60 (54–68) mm Hg. At 60 days post-ECMO initiation, the estimated probabilities of occupation in each state were 6% (95% CI 3–14) for state 1, 18% (11–28) for state 2, 45% (35–56) for state 3, and 31% (22–42) for state 4. 35 (42%) patients had major bleeding and four (5%) had a haemorrhagic stroke. 30 patients died.InterpretationThe estimated 60-day survival of ECMO-rescued patients with COVID-19 was similar to that of studies published in the past 2 years on ECMO for severe ARDS. If another COVID-19 outbreak occurs, ECMO should be considered for patients developing refractory respiratory failure despite optimised care
