Risk Factors for Post-Traumatic Stress Disorder after Childbirth: A Systematic Review
Background: Post-traumatic stress disorder (PTSD) after birth has generated a growing
interest in recent years. Although some risk factors associated with PTSD have been studied, information
is still scarce to date on risk factors associated with PTSD. This systematic review aims to
identify risk factors associated with the diagnosis of PTSD after childbirth. Methods: We searched on
PubMed,Web of Science and SCOPUS databases, from inception to May 2022. Quality assessment
of the articles was performed using the Newcastle-Ottawa Quality Assessment (“NOQAS”) scale.
This systematic review was performed according to the PRISMA guidelines. Inclusion criteria were
women with age 18 years; articles in English or Spanish; articles focused on physical, social, psychological,
medical-obstetric, and environmental risk factors. Results: A total of n = 17,675 women
were included among the studies in this systematic review. The main risk factors associated with
PTSD after birth were obstetric interventions and obstetric violence such as emergency caesarean
section or a non-compliant birth plan, a previous mental illness, having suffered from of a traumatic
event or depression and/or anxiety, and having poor social support throughout pregnancy and/or
during birth. Conclusions: Obstetric interventions, obstetric violence, experiencing a traumatic event
or depression and/or anxiety, and a previous mental illness are factors associated with the diagnosis
of PTSD after birth. Protective factors are multiparity, adherence to the mother’s birth plan and
skin-to-skin contact.Junta de Andalucia RH-0069-202
Catalizador a base de cerio para la eliminación de formaldehído
La presente investigación contribuye al estudio de la degradación de formaldehído, mediante la reacción de Oxidación Húmeda Catalítica (CWO), utilizando catalizadores de óxidos mixtos de cerio, cobre y cobalto soportados en alfa y gama alúmina comercial, con un alto contenido de Ce en relación a los otros dos metales, con el fin de aumentar la eficiencia en la eliminación del contaminante mediante la oxidación total del formaldehído, dadas las propiedades redox que presenta el Ce. En este trabajo se verificó una mayor degradación del contaminante con el aumento tanto de la temperatura de reacción, como de la presión del agente oxidante.This research contributes to the study of formaldehyde degradation, by means of the Catalytic Wet Oxidation (CWO) reaction, using mixed oxides catalysts of cerium, copper and cobalt supported in alpha and gamma alumina commercial both catalysts, with a high Ce content in in relation to the other two metals, in order to increase the efficiency in the elimination of the contaminant by means of the total oxidation of formaldehyde, given the redox properties that Ce presents. In this work a greater degradation of the contaminant was verified after the increase of both the reaction temperature, as of the oxidizing agent pressure
Síntesis de hidroxiapatita con hierro
La síntesis de hidroxiapatita (HAp), con sus diversas estructuras, morfologías y texturas, ha estimulado un gran interés en la investigación académica e industrial para numerosas aplicaciones de catálisis heterogénea. En los últimos treinta años, se han desarrollado varias rutas para sintetizar polvos de HAp. Ante la búsqueda de nuevos catalizadores que resulten más eficientes para ciertas reacciones que buscan la mineralización de contaminantes orgánicos presentes en agua, el presente trabajo de investigación pretende contribuir con el desarrollo de catalizadores a base de hidroxiapatita con hierro, cuidando de manera muy particular la tasa de goteo al incorporar la fuente de fosforo usando el método de síntesis húmeda. Los resultados muestran que la incorporación de hierro no modifica la estructura cristalina de la hidroxiapatita por lo que sus propiedades fisicoquímicas se verían favorecidas tras la incorporación del hierro.The synthesis of hydroxyapatite (HAp), with its diverse structures, morphologies and textures, has stimulated a great interest in academic and industrial research for numerous applications of heterogeneous catalysis. In the last thirty years, several synthetic routes have been developed to produce HAp powders. In the search for new catalysts that are more efficient for certain reactions that seek the mineralization of organic contaminants present in water, this research aims to contribute to the development of catalysts based on hydroxyapatite with iron, paying particular attention to the rate of drippings by incorporating the phosphorus source using the wet synthesis method. The results show that the incorporation of iron does not modify the crystalline structure of hydroxyapatite, so its physicochemical properties would be favored after iron incorporation
Capacidad de adsorción de un material híbrido en la remoción del ion fluoruro
La contaminación de agua de consumo humano por fluoruros se ha convertido en un problema de salud pública en las últimas décadas, debido a que la ingesta continua de agua contaminada con altas concentraciones de fluoruros ocasiona fluorosis esquelética y dental, las cuales son enfermedades irreversibles y afectan principalmente a niños en etapas de crecimiento. En este trabajo, con el fin de contribuir a la solución de este problema, se preparó un material híbrido constituido por una zeolita natural acondicionada con hierro e hidroxiapatita, y para determinar la capacidad de adsorción del material adsorbente se realizaron isotermas de adsorción y se determinó la cinética de adsorción. El material presentó un buen ajuste tanto al modelo de Freundlich como al de Langmuir y una excelente capacidad de adsorción de 73.53 mg F¯/g. El estudio cinético demostró un ajuste al modelo de Pseudo-segundo orden, el cual indica que el proceso de adsorción se lleva a cabo mediante el mecanismo de quimisorción.The contamination of water for human consumption by fluorides has become a public health problem in recent decades, because the continuous intake of water contaminated with high concentrations of fluorides causes skeletal and dental fluorosis, which are irreversible diseases and affect mainly to children in stages of growth. In this work, in order to contribute to solving this problem, a hybrid material consisting of a natural zeolite conditioned with iron and hydroxyapatite was prepared, and to determine the adsorption capacity of the adsorbent material, adsorption isotherms were carried out and determined adsorption kinetics. The material presented a good fit to both the Freundlich and Langmuir models and an excellent adsorption capacity of 73.53 mg F¯/g. The kinetic study demonstrated a fit to the Pseudo-second order model, which indicates that the adsorption process is carried out through the chemisorption mechanism
¿Qué queda de mí?
Este libro es una reclamación a quienes hemos sido, somos o seremos docentes. A quienes no hemos respetado a las personas que se han puesto junto a nosotros y nosotras, confiando su bien más preciado: la libertad. Estas páginas denuncian cada vez que convertimos una visión en la visión, una emoción en la emoción, un saber en el saber, un comportamiento en el comportamiento. Es un grito contra la imposición, la normalización, la neutralización y la universalización de una perspectiva particular. Una pugna contra cada proceso que no se ha conectado con las vidas de los aprendices.

The EUropean Network of National Schizophrenia Networks Studying Gene–Environment Interactions (EU-GEI): Incidence and First-Episode Case–Control Programme
Funder: FP7 Ideas: European Research Council; doi: http://dx.doi.org/10.13039/100011199; Grant(s): HEALTH-F2-2010-241909Abstract: Purpose: The EUropean Network of National Schizophrenia Networks Studying Gene–Environment Interactions (EU-GEI) study contains an unparalleled wealth of comprehensive data that allows for testing hypotheses about (1) variations in incidence within and between countries, including by urbanicity and minority ethnic groups; and (2) the role of multiple environmental and genetic risk factors, and their interactions, in the development of psychotic disorders. Methods: Between 2010 and 2015, we identified 2774 incident cases of psychotic disorders during 12.9 million person-years at risk, across 17 sites in 6 countries (UK, The Netherlands, France, Spain, Italy, and Brazil). Of the 2774 incident cases, 1130 cases were assessed in detail and form the case sample for case–control analyses. Across all sites, 1497 controls were recruited and assessed. We collected data on an extensive range of exposures and outcomes, including demographic, clinical (e.g. premorbid adjustment), social (e.g. childhood and adult adversity, cannabis use, migration, discrimination), cognitive (e.g. IQ, facial affect processing, attributional biases), and biological (DNA via blood sample/cheek swab). We describe the methodology of the study and some descriptive results, including representativeness of the cohort. Conclusions: This resource constitutes the largest and most extensive incidence and case–control study of psychosis ever conducted
