Environmental and psychopathological predictors of clinical high-risk of psychosis in adolescence.

OBJECTIVES: Clinical high-risk psychosis (CHRp) samples can be heterogeneous, consisting essentially of people with not only psychotic-like experiences but also nonspecific symptoms that may reflect common mental disorders such as depression, anxiety, or substance abuse pathologies. Few studies have attempted to analyze and understand psychosis risk in relation to both environmental (ER) and psychopathological risk (PsR) factors. This study aimed to determine the clinical risk of psychosis in adolescents. METHODS: A representative sample of 1824 Spanish adolescents from the general population was evaluated using different scales to thoroughly examine the possible interaction of CHRp with various ER and PsR factors. Partial correlations were calculated to assess the relationships between the variables. A series of hierarchical linear regression models were then used to obtain a CHRp predictor model. RESULTS: The CHRp predictor model indicated that PsR was the most significant determining factor, explaining 22% of the total associated variance of CHRp. However, the ER factor also emerged as a significant predictor of high-risk psychosis (accounting for 9% of the variance). CONCLUSIONS: A predictive model for CHRp in adolescents was found, in which common psychological problems were presented as more determinant risk factors than ER disruptors. Furthermore, certain transdiagnostic processes, such as psychological inflexibility, may play a central role in the development of mental health problems, including psychosis. Specifying the mechanisms underlying the emergence of CHRp in adolescence is the key to optimizing the focus of preventive therapeutic interventions in these early stages.

Close-Space Sublimation as a Scalable Method for Perovskite Solar Cells.

Vacuum techniques for perovskite photovoltaics (PV) are promising for their scalability but are rarely studied with techniques readily adaptable for industry. In this work, we study the use of close-space sublimation (CSS) for making perovskite solar cells, a technique that has seen widespread use in industry, including in PV, and benefits from high material-transfer and low working pressures. A pressed pellet of formamidinium iodide (FAI) can be used multiple times as an organic source, without needing replacement. Using CSS at a rough vacuum (10 mbar), efficient cesium formamidinium lead iodide perovskite based solar cells are obtained reaching a maximum photoconversion efficiency (PCE) of 18.7%. They maintain their performance for >650 h when thermally stressed at 85 °C in a nitrogen environment. To explain the initial rise in PCE upon heating, we used drift-diffusion simulations and identified a reduction in bulk trap density as the primary factor.

Estatus nosológico de la acumulación compulsiva: ¿subtipo de trastorno obsesivo-compulsivo o entidad clínica independiente? / Nosological status of compulsive hoarding: obsessive-compulsive disorder subtype or independent clinical entity

En el presente estudio teórico se revisan los principales hallazgos e investigaciones respecto al estatus nosológico de la acumulación compulsiva. En concreto, se exponen las evidencias empíricas disponibles para poder determinar su independencia o no del trastorno obsesivo compulsivo (TOC), patología mental donde tradicionalmente ha sido incluida como un subtipo o dimensión más de la misma. En relación a esta cuestión, los resultados recogidos en la literatura científica sostienen que las personas con acumulación compulsiva, a diferencias de "otros" sujetos con TOC, presentan características distintivas en diversos criterios externos, a saber: variables sociodemográficas, personalidad premórbida, grado de insight, factores genéticos y neuroanatómicos, correlatos neuropsicológicos, curso y nivel de disfuncionalidad y, por último, respuesta al tratamiento. Dichas conclusiones son discutidas valorando la propuesta de creación de una nueva entidad clínica denominada "trastorno por acumulación"

This theoretical study reviews the main research and findings on the nosological status of compulsive hoarding. Specifically, it describes available empirical evidence in order to determine their independence or inclusion within the obsessive-compulsive disorder (OCD), a mental disorder in which it has traditionally been included as one more subtype or dimension. Regarding this issue, the results found in the scientific literature show that persons with compulsive hoarding have distinct characteristics indifferent external criteria like sociodemographic variables, premorbid personality, degree of insight, neuroanatomical and genetic factors, neuropsychological profile, clinical course, levels of dysfunctionality and finally, treatment outcome. These conclusions are discussed and the proposal for the creation of a new clinical entity called "hoarding disorder" is evaluated

Surveillance of hospitalized and outpatient cases of pertussis in Catalonia from 2003 to 2009.

Pertussis is a vaccine-preventable disease that generates a large number of cases and hospitalizations. In Catalonia, the vaccination schedule includes three doses of vaccine at 2, 4 and 6 mo and two booster doses at 18 mo and 4-6 y. In 2002, DTPw was replaced by DTPa. The aim of this study was to determine how the vaccination status affects pertussis hospitalizations. Cases were obtained from the epidemiological surveillance system of the Generalitat of Catalonia from 2003 to 2009. Hospitalization, immunization status and type of vaccine received in reported cases were analyzed. OR and 95% confidence intervals (CI) were calculated. To control the effect of age (< 6 mo and ≥ 6 mo) Mantel-Haenszel OR (ORMH) were calculated; statistical significance was established as p < 0.05. During the study period, 1538 cases were reported. Cases below vaccination age (< 2 mo) were excluded. A total of 265 cases were hospitalized: 137 (51.7%) had no vaccine administrated, 104 (39.2%) were correctly vaccinated according to age and 24 (9.1%) were poorly vaccinated. Correct vaccination protected against hospitalization (ORMH: 0.33; 95%CI: 0.23-0.47). Of hospitalized cases, 38 (14.3%) had received DTPw and 91 (34.2%) DTPa. Both vaccines were effective in avoiding hospitalization, and comparison showed no differences (ORMH: 0.73; 95%CI: 0.46-1.14). We highlight the importance of a correct follow-up immunization schedule in reducing the number of cases and hospitalizations.

Moxibustión en la malposición fetal / Moxibustion in fetal malposition

Introducción: La incidencia de la presentación fetal podálica en España es del 3,8%. La moxibustión es parte integral de la milenaria medicina tradicional china. La técnica consiste en la colocación de un palillo incandescente de Artemisia vulgaris a unos pocos centímetros del punto de acupuntura Zhiyin (punto 67 del meridiano de vejiga, ubicado en la base externa de la uña del quinto dedo del pie). Los objetivos son: 1. Conocer el porcentaje de fetos que han rotado a cefálica mediante la moxibustión en gestantes que presenten una malposición fetal a partir de las 32 semanas de embarazo; 2. Identificar las complicaciones materno-fetales en la aplicación de la técnica. Sujetos: Se estudiaron 18 gestantes de más de 32 semanas de embarazo. Material y métodos: Mediante un estudio descriptivo de intervención, analizamos el porcentaje de fetos que rotaron a presentación cefálica. Resultados: Quince gestantes (83,9%) realizaron el tratamiento adecuadamente y las 3 restantes (16,7%) lo realizaron de manera ocasional y terminaron con una cesárea electiva por nalgas. Conclusiones: Parece razonable concluir que el cumplimiento del tratamiento influye en el tipo de parto (χ2= 12,600; gl= 1; p= 0,000), aunque no modifica el Apgar del recién nacido. Esta técnica se presenta como una alternativa económica, segura, sencilla y práctica para la versión fetal de la presentación podálica (AU)

Introduction: The incidence of fetal breech presentation in Spain is of 3.8%. Moxibustion is an integral part of the ancient traditional Chinese medicine. The technique involves placing an incandescent stick of Artemisia vulgaris a few inches of the acupuncture point Zhiyin (point 67 of the bladder meridian, located at the outer base of the nail of the fifth toe). The objectives are: 1. To find out what percentage of fetuses have turned around to a cephalic presentation due to moxibustion in pregnant women displaying fetal malposition after the 32nd week of pregnancy; 2. To identify any materno-fetal complications associated with the use of the technique. Subjects: A total of eighteen pregnant women were studied with more than 32 weeks of gestation. Material and methods: Through a descriptive study with one group intervention, we analyzed the percentage of cephalic fetus that rotated with this therapy. Results: Fifteen pregnant women (83.9%) did the treatment properly; three pregnant women (16.7%) carried out the treatment on an occasional basis and ended with a caesarean section due to buttocks. Conclusions: It seems reasonable to say that compliance with the treatment influences the type of delivery (2= 12.600; gl= 1; p= 0.000), but does not modify the Apgar of the newborn. This technique is presented as an economic, safe, simple and practical alternative, for the fetal version of breech presentation (AU)

El plan de parto a debate. ¿Qué sabemos de él? / The birth plan. What do we know about it?

El objetivo de este artículo es buscar el nivel de evidencia actual del plan de parto mediante una revisión bibliográfica. Los planes de parto los presentan mujeres que demandan una atención de calidad. Sirven para exponer sus opiniones y deseos, y mejorar la comunicación con los profesionales. No siempre mejoran su satisfacción, pueden irritar a los profesionales y no siempre se basan en la mejor evidencia existente. El plan de parto es un documento útil para fomentar la participación de los padres en el nacimiento de sus hijos. Las matronas que atienden a las madres durante la gestación deben orientar a las parejas en la elaboración de los planes para que puedan construir expectativas realistas y flexibles, con el fin de alejar los miedos y favorecerla confianza en ellas mismas y su entorno (AU)

The aim of this paper is to seek current level of evidence birth planthrough a literature review. Delivery plans are presented by women who demand quality care. They serve to present their views and wishes and improve communication with professionals. Not always improve your satisfaction, can irritate the professionals and not always based on the best evidence available. The birth plan is a useful document to promote parental involvement in the birth of their children. Midwives provide care during the pregnancy, should guide their development so they can build expectations realistic and flexible in order to ward off fears by promoting confidence in themselves and their environment (AU)
