RESUMO

Antecedentes y Objetivo. El impacto psicológico de la hospitalización en los pacientes ingresados en larga estancia es variable y se muestra en respuesta al estrés y en el desempeño del rol de enfermo del paciente hospitalizado. El objetivo de esta investigación fue detectar las principales alteraciones psicológicas que sufren estos pacientes, y diseñar un protocolo para su manejo. Material y Método. Empleamos instrumentos como el Inventario de ansiedad, el Inventario de depresión rasgo-estado y el Cuestionario de estrategias de afrontamiento Sandin y Chorot. Realizamos un estudio descriptivo, guiado por el paradigma empírico analítico, corte cuantitativo, diseño no experimental, con una población total de 50 pacientes y una muestra de 15, muestreo no probabilístico, de tipo intencional, teniendo en cuenta los criterios de inclusión y exclusión propios de la investigación. Resultados. Entre los aspectos más relevantes encontrados marcados estados depresivos, ansiedad rasgo, baja expresión emocional abierta, y alta reevaluación positiva, que es de vital importancia, para el manejo de estos pacientes con larga estancia hospitalaria. Conclusiones. Según los datos de nuestro estudio, la larga estancia hospitalaria se relaciona generalmente con el desprendimiento del individuo de su medio natural, que puede generarle estados de tristeza, ansiedad y desencadenar efectos negativos como la baja expresión emocional. Estas características pueden servir de guía a los profesionales de la salud, por lo que presentamos un diseño de protocolo de manejo efectivo que ayude al paciente a afrontar mejor las dificultades que se le presentan en el ámbito hospitalario (AU)


Background and Objectives. The psychological impact of hospitalization on patients admitted for a long period is variable and it´s shown as an answer to stress and on how ill the hospitalized patient is. The objective of this investigation was to determine the main psychological disturbances and to design a protocol to know how to handle long-stay patients at the hospital. Patients and Method. In this investigation were applied tools such as the Anxiety inventory, Characteristic-status depression inventory and Sandin &Chorot strategies of confrontation test. We conduct a descriptive type study, guided by the annalistic empiric paradigm, quantity cut, non-experimental design, with a population of 50 patients and a sample of 15, non-probabilistic sample, intentional type, inclusion and exclusion criteria from the investigation were taken into account. Results. Among the most relevant aspects found, were discovered prominent depressive status, anxiety, low opened emotional expression, high positive reevaluation, which is very relevant to handle all long-stay patients at the hospital. Conclusions. Long-stay hospitalization is normally connected to the individual´s detachment of its natural environment, which can generate on patient states of sadness, anxiety and to trigger negative effects such as low emotional expression. These characteristics can be useful as a guide for health professionals, and we so, we design a model of more effective protocol, which would help the patient to face, in a better way, all the difficulties presented in the hospital field (AU)

RESUMO

The degradation of sedimentary particulate organic carbon (POC) is a key carbon cycle process that fuels the deep subseafloor biosphere. The reactivity of POC is expected to decrease with increasing sediment age, severely restricting the energy available to microorganisms. Conversely, increasing temperatures during burial have been proposed to stimulate POC degradation, possibly supplying significant energy to the deep biosphere. To test the importance of temperature, we assembled POC measurements in two global sets of drill sites where sediments underwent either relatively low or high temperatures during burial, which should have resulted in different rates of POC degradation. For ages 5-10 Ma, the decrease of the average POC content with burial is clearly more pronounced in the sites with high temperature histories. Our results support the hypothesis that temperature is one of the fundamental controls on the rate of POC degradation within deeply buried marine sediments.

RESUMO

Virus dissociation and inactivation by high pressure have been extensively studied in recent decades. Pressure-induced dissociation of viral particles involves a reduction in the Gibbs free energy of dissociation and a negative change in volume. In this work, we investigated the combined effect of high pressure and temperature on the dissociation of tobacco mosaic virus (TMV). We assumed the presence of two states of TMV with different tendencies to dissociate. Thus one form presents a low tendency (L) and the other a high tendency (H) to dissociate. Based on the model described here, the L-H transition was favored by an increase in pressure and a decrease in temperature. The volume change of dissociation was pressure- and temperature-dependent, with a highly negative value of -80 mL/mol being recorded at 0 °C and atmospheric pressure. The entropy and enthalpy of dissociation were very temperature- and pressure-dependent, with values of entropy of 450 to -1300 kJ/mol and values of enthalpy of 5.5 × 10(4) to 2.4 × 10(4) kJ/mol. The dissociation of TMV was enthalpy-driven at all temperatures and pressures investigated. Based on these findings, we conclude that the model presented allows accurate predictions of viral dissociation behavior in different experimental conditions.
