Adapting the revised prenatal coping inventory (NuPCI) for use in a Spanish population

Objective: To adapt the Revised Prenatal Coping Inventory (NuPCI) for the evaluation of prenatal stress coping strategies utilised by Spanish women. Methods: A cross-sectional study was performed to evaluate the psychometric properties of NuPCI adapted for a Spanish population. Two hundred and sixty one puerperium women completed the NuPCI at the time of discharge after childbirth. Instrument construct validity was evaluated using subscale item correlations. Internal consistency was assessed using Cronbach’s a test. Results: Items from each subscale (Preparation, Avoidance and Spiritual – Positive Coping) were significantly correlated with the global result (p¿¿0.7). The most frequently used coping strategy was Preparation and the least used was Avoidance. Utilisation of the coping strategies with Preparation decreased with increasing parity (p¿=¿.002) and greater prenatal stress was associated with increased use of the Avoidance coping strategy (p¿<¿.001). Conclusions: The NuPCI adapted for Spanish women demonstrates good psychometric properties for evaluating the three types of prenatal stress coping strategies: Preparation, Avoidance and Spiritual – Positive Coping. Results were similar to those presented by the instrument in its English language version

Biopsychosocial factors related to the length of hospital stay in older people

This study aimed to know what variables influence increased length of hospital stay. A descriptive, cross-sectional study was conducted through an integrated geriatric assessment of 81 people over 65 years of age, admitted to a tertiary acute care hospital. Data were collected through the Pfeiffer Scale, Barthel Index, Goldberg Questionnaire, Family APGAR and Gijón Scale. The length of hospital stay increased in people over 80 years, people living alone or in a retirement home, patients with great physical dependence and those with a risk or problem of social exclusion. The most influential variable for longer hospitalization was cognitive impairment (pEste estudio tuvo como objetivo conocer qué variables influyen en el aumento de la duración de la estancia hospitalaria. Se trata de un estudio descriptivo transversal en el que se realizó una Valoración Geriátrica Integral a 81 personas mayores de 65 años de edad que ingresaron en un hospital de agudos de tercer nivel. Para ello, los datos fueron recogidos por medio de la Escala de Pfeiffer, el Índice de Barthel, el Cuestionario de Goldberg, el APGAR familiar y la Escala de Gijón. Se observó un aumento de la duración de la estancia hospitalaria entre los mayores de 80 años, las personas que vivían solas o en una residencia geriátrica, los pacientes que presentaban gran dependencia física y también, entre quienes tenían un riesgo o problema de exclusión social. La variable que más influyó en la mayor duración de la hospitalización fue el deterioro cognitivo (pEste estudo teve como objetivo conhecer quais as variáveis que influenciam o aumento do tempo de internação hospitalar. Trata-se de estudo descritivo e transversal, conduzido mediante ampla avaliação geriátrica de 81 pessoas com mais de 65 anos, internadas em hospital terciário de cuidados agudos. Os dados foram coletados através da Escala Pfeiffer, Índice de Barthel, Questionário de Goldberg, Apgar da Família e Escala de Gijón. Observou-se aumento no tempo de internação entre pessoas com mais de 80 anos, pessoas que vivem sozinhas ou em lar de idosos, pacientes que tinham grande dependência física, e entre aqueles com algum risco ou problema de exclusão social. A variável mais influente, para a maior duração da hospitalização, foi a deterioração cognitiva (p<0,05), em comparaç��o à maior colaboração do paciente sem essa condição ou ao seu desejo de superar a fase aguda da patologia que levou à internação hospitalar

Evolutionary and pulsational properties of white dwarf stars

Abridged. White dwarf stars are the final evolutionary stage of the vast majority of stars, including our Sun. The study of white dwarfs has potential applications to different fields of astrophysics. In particular, they can be used as independent reliable cosmic clocks, and can also provide valuable information about the fundamental parameters of a wide variety of stellar populations, like our Galaxy and open and globular clusters. In addition, the high densities and temperatures characterizing white dwarfs allow to use these stars as cosmic laboratories for studying physical processes under extreme conditions that cannot be achieved in terrestrial laboratories. They can be used to constrain fundamental properties of elementary particles such as axions and neutrinos, and to study problems related to the variation of fundamental constants. In this work, we review the essentials of the physics of white dwarf stars. Special emphasis is placed on the physical processes that lead to the formation of white dwarfs as well as on the different energy sources and processes responsible for chemical abundance changes that occur along their evolution. Moreover, in the course of their lives, white dwarfs cross different pulsational instability strips. The existence of these instability strips provides astronomers with an unique opportunity to peer into their internal structure that would otherwise remain hidden from observers. We will show that this allows to measure with unprecedented precision the stellar masses and to infer their envelope thicknesses, to probe the core chemical stratification, and to detect rotation rates and magnetic fields. Consequently, in this work, we also review the pulsational properties of white dwarfs and the most recent applications of white dwarf asteroseismology.Comment: 85 pages, 28 figures.

Compreendendo o sofrimento humano frente à doença: manifestações, contexto e estratégias

The aim of this study is to understand the suffering of a patient with an illness, by using a secondary research method, that is, a qualitative meta-study. The primary data source of the meta-study includes “biographical reports”. This project is based on a case study, in which the first-hand experiences of a patient with an illness were collected. The findings of the reports were compiled using the Archivos de la Memoria collection of the Index Foundation (Granada, Spain) and journals specialized in editing these materials. A selection of 20 biographical reports was targeted. The results of the meta-study show that suffering is a multidimensional process within a framework of ambiguous feelings. The suffering involves family and social network participation. Patients develop a range of strategies to overcome the illness. One of the effects is the fear of illness relapse or worsening.El propósito de este trabajo es comprender la experiencia del padecimiento ante la enfermedad mediante la utilización de un método de investigación secundaria, un meta estudio cualitativo. La fuente de datos primarios ha sido el relato biográfico, un diseño basado en el estudio de caso que recoge la experiencia en primera persona, en este caso, ante la enfermedad; la localización de relatos se ha hecho a través del fondo Archivos de la Memoria de la Fundación Index y de revistas especializadas en la edición de estos materiales. Se seleccionaron 20 relatos biográficos. Los resultados del meta estudio muestran que el padecimiento es un proceso multidimensional, caracterizado por la ambigüedad de sentimientos. Es un fenómeno que comparte la familia y la red social. Las personas enfermas desarrollan diferentes estrategias de afrontamiento y es manifiesto el miedo a la recaída o el empeoramiento
