Dysfunctional psychological responses among Intensive Care Unit nurses: a systematic review of the literature

AbstractOBJECTIVETo systematically review evidence on dysfunctional psychological responses of Intensive Care Units nurses (ICUNs), with focus on anxiety and depressive symptoms and related factors.METHODA literature search was performed in CINAHL, PubMed and Scopus databases, from 1999 to present, along with a critical appraisal and synthesis of all relevant data. The following key words, separately and in combination, were used: "mental status" "depressive symptoms" "anxiety" "ICU nurses" "PTSD" "burnout" "compassion fatigue" "psychological distress".RESULTSThirteen quantitative studies in English and Greek were included. The results suggested increased psychological burden in ICUNs compared to other nursing specialties, as well as to the general population.CONCLUSIONSStudies investigating psychological responses of ICUNs are limited, internationally. Future longitudinal and intervention studies will contribute to a better understanding of the phenomenon.

La chaîne des secours: le modèle vaudois [An efficient example of a Swiss pre-hospital chain of survival: the state of Vaud model].

The state of Vaud model of the pre-hospital chain of survival is an example of an efficient way to deal with pre-hospital emergencies. It revolves around a centrally located dispatch center managing emergencies according to specific key words, allowing dispatchers to send out resources among which we find general practitioners, ambulances, physician staffed fast response cars or physician staffed helicopters and specific equipment. The Vaud pre-hospital chain of survival has been tailored according to geographical, demographical and political necessities. It undergoes constant reassessment and needs continuous adaptations to the ever changing demographics and epidemiology of pre-hospital medicine.

Impactos Decorrentes da Expansão da Cidade de Assomada, Município de Santa Catarina – Cabo Verde

Esta dissertação tem por finalidade evidenciar os “Impactos Decorrentes da Expansão da Cidade de Assomada”. Propõe-se ainda, analisar a relação urbanorural no município de Santa Catarina, Cabo Verde. Essa análise incidiu sobre os dados da sua ocupação, que remonta à 2ª metade do século XIX, no decurso da crise e decadência da primeira cidade de Cabo Verde (Ribeira Grande, atual Cidade- Velha) e às conjunturas regionais e nacionais que condicionaram sua trajetória, bem como, os principais agentes intervenientes na transformação do espaço urbano de Assomada (Estado, proprietários de terra e comerciantes), sobretudo, no período que decorre de 1961 a 2003. A pesquisa empreendida demonstra que a “ruralidade” é um dos aspectos fundamentais de Santa Catarina, abrangendo 21,3% da população rural do território nacional e 37,9% da ilha de Santiago. Do ponto de vista urbanístico, o mapeamento da evolução da cidade de Assomada, referente à área ocupada pelas edificações nesse lapso de tempo, permite-nos perceber um crescimento bastante acelerado desse espaço urbano, sobretudo, a partir dos anos 90. Dois aspectos importantes se encontram na base dessa transformação: a Independência Nacional ocorrida em 1975 e a Emigração. Com a Independência, o país passou a beneficiar de amplos programas de cooperação internacional o que veio a reforçar a sua importância econômica e política, visualizada através de projetos industrializantes, infra-estruturas e equipamentos de diversas naturezas. Esses investimentos foram por sua vez reforçados por aportes dos emigrantes, que passaram a ser um dos parceiros fundamentais no desenvolvimento de Santa Catarina, através de iniciativas privadas e empresariais, como a construção de residências e constituição de empresas. A análise do indicador uso e ocupação do solo urbano permitiu-nos identificar alguns impactos ambientais causados, sobretudo, pela falta de instrumentos de gestão urbanística, ausência de cadastro municipal e uma deficiente fiscalização dos órgãos administrativos.

Estudi sobre la qualitat de vida de les persones amb demència ateses a la Unitat d'avaluació de deteriorament cognitiu de l'Hospital de la Santa Creu

OBJECTIU: determinar la qualitat de vida de les persones amb demència ateses en una unitat avaluadora de deteriorament cognitiu. MÈTODE: estudi descriptiu transversal amb una mostra consecutiva no probabilística, formada per 42 persones amb demència tipus Alzheimer lleu o moderada i els seus cuidadors. La Qualitat de Vida (QV) es va avaluar amb el qüestionari QoL-AD (Quality of Life Alzheimer’s Disease) en les versions per al pacient (QoL-ADp) i per al cuidador (QoL-ADc). RESULTATS: la mitjana de puntuació del QoL-ADp va ser de 35,38 punts (DE = 5,24) i del QoL-Adc, de 30,60 (DE 5,33). La diferència entre aquests resultats és significativa (p&0,001). Els pacients amb simptomatologia depressiva i els seus cuidadors van puntuar significativament més baix el QoL-AD (p&0,001). En les freqüències per ítems del QoL-ADp s’observa que: més del 75% van valorar com a bona/excel·lent les condicions de vida, família, matrimoni/relació estreta, vida social, situació financera i vida en general; el 61% valoraren bona/excel·lent la capacitat per realitzar tasques a casa; prop del 50% pensava que l’estat d’ànim, l’energia, la salut física, la capacitat per fer coses per diversió i la visió de si mateixos era dolenta/regular, i el 85,7% opinava que la seva memòria era dolenta/regular. CONCLUSIONS: els resultats obtinguts en el QoL-AD no difereixen dels obtinguts en altres investigacions. Suggereixen que les intervencions que genera l’avaluació de la QV en la pràctica clínica inclouen aspectes centrats pròpiament en la malaltia i aspectes vinculats amb les relacions socials.

A press database on natural risks and its application in the study of floods in Northeastern Spain

The aim of this work is to introduce a systematic press database on natural hazards and climate change in Catalonia (NE of Spain) and to analyze its potential application to social-impact studies. For this reason, a review of the concepts of risk, hazard, vulnerability and social perception is also included. This database has been built for the period 1982¿2007 and contains all the news related with those issues published by the oldest still-active newspaper in Catalonia. Some parameters are registered for each article and for each event, including criteria that enable us to determine the importance accorded to it by the newspaper, and a compilation of information about it. This ACCESS data base allows each article to be classified on the basis of the seven defined topics and key words, as well as summary information about the format and structuring of the new itself, the social impact of the event and data about the magnitude or intensity of the event. The coverage given to this type of news has been assessed because of its influence on construction of the social perception of natural risk and climate change, and as a potential source of information about them. The treatment accorded by the press to different risks is also considered. More than 14 000 press articles have been classified. Results show that the largest number of news items for the period 1982¿2007 relates to forest fires and droughts, followed by floods and heavy rainfalls, although floods are the major risk in the region of study. Two flood events recorded in 2002 have been analyzed in order to show an example of the role of the press information as indicator of risk perception.

Changes in chromosomal polymorphism and global warming: The case of Drosophila subobscura from Apatin (Serbia)

Abstract In this study, chromosomal inversion polymorphism data for a natural population of Drosophila subobscura from a swampy region near the town of Apatin (Serbia) were compared with data for the same population collected approximately 15 years earlier. The pattern of chromosomal inversion polymorphism changed over time. There were significant increases in the frequency of characteristic southern latitude ("warm" adapted) chromosomal arrangements and significant decreases in the frequency of characteristic northern latitude ("cold" adapted) chromosomal arrangements in the O and U chromosomes. The chromosomal arrangements O3+4 and O3+4+22 (derived from the O3+4 arrangement)showed significant increases in 2008 and 2009 with regard to the 1994 sample. There was also a significant increase (~50%) in the U1+2 arrangement, while U1+8+2 (a typical southern arrangement) was detected for the first time. Since the Apatin swampy population ofD. subobscura has existed for a long time in a stable habitat with high humidity that has not been changed by man our results indicate that natural selection has produced chromosomal changes in response to the increase in temperature that has occurred in the Balkan Peninsula of central southeastern European. Key words: chromosomal inversions, Drosophila subobscura, global warming, karyotypes.

Statistical properties of new neutrality tests against population growth.

A number of statistical tests for detecting population growth are described. We compared the statistical power of these tests with that of others available in the literature. The tests evaluated fall into three categories: those tests based on the distribution of the mutation frequencies, on the haplotype distribution, and on the mismatch distribution. We found that, for an extensive variety of cases, the most powerful tests for detecting population growth are Fu"s FS test and the newly developed R2 test. The behavior of the R2 test is superior for small sample sizes, whereas FS is better for large sample sizes. We also show that some popular statistics based on the mismatch distribution are very conservative. Key words: population growth, population expansion, coalescent simulations, neutrality tests

Spontaneous mirror symmetry breaking in the limited enantioselective autocatalysis model: abyssal hydrotermal vents as scenario for the emergence of chirality in prebiotic chemistry

The emergence of chirality in enantioselective autocatalysis for compounds unable to transform according to the Frank-like reaction network is discussed with respect to the controversial limited enantioselectivity (LES) model composed of coupled enantioselective and non-enantioselective autocatalyses. The LES model cannot lead to spontaneous mirror symmetry breaking (SMSB) either in closed systems with a homogeneous temperature distribution or in closed systems with a stationary non-uniform temperature distribution. However, simulations of chemical kinetics in a two-compartment model demonstrate that SMSB may occur if both autocatalytic reactions are spatially separated at different temperatures in different compartments but coupled under the action of a continuous internal flow. In such conditions, the system can evolve, for certain reaction and system parameters, toward a chiral stationary state; that is, the system is able to reach a bifurcation point leading to SMSB. Numerical simulations in which reasonable chemical parameters have been used suggest that an ade- quate scenario for such a SMSB would be that of abyssal hydrothermal vents, by virtue of the typical temper- ature gradients found there and the role of inorganic solids mediating chemical reactions in an enzyme-like role. Key Words: Homochirality Prebiotic chemistry.

High altitude Chironomidae (Diptera) of Serra da Estrela (Portugal): Additions to the Portuguese and Iberian Peninsula fauna

A Chironomidae (Diptera) fauna list for headwater streams of high altitude areas in Serra da Estrela (Portugal) is presented, doubling the previously established species richness for the region. The findings include 17 new records for Portugal, which represent an increase to 219 species for the Continental Portugal Chironomidae fauna. Two new records were detected for the Iberian Peninsula: one species (Tvetenia duodenaria), and one subgenusPsectrocladius (Mesopsectrocladius); and the presence of the genus Natarsia is confirmed. The last two occurrences correspond to monoespecific taxa of the Palearctic region. However, as taxonomic identification has been based on larval material, instead of pupae, pupal exuviae or imagoes, species level assignment is still uncertain. Key words: Diptera, Chironomidae, high mountain streams, Serra da Estrela, Portugal, Iberian Peninsula. RESUMEN Quironómidos (Diptera, Chironomidae) de alta montaña de la Sierra de Estrela (Portugal) y adiciones a la fauna de Portugal y la Península Ibérica Se presenta una lista de especies de Chironomidae (Diptera) recolectados en los ríos de cabecera de zonas de alta montaña en la Serra da Estrela (Portugal). Con esta aportación se duplica la riqueza de especies regional conocida hasta el momento y se eleva la fauna de quironómidos del Portugal continental a 219 especies. Se incluyen dos nuevas citas para la Península Ibérica, una especie (Tvetenia duodenaria) y un subgéneroPsectrocladius (Mesopsectrocladius), y se confirma la presencia del género Natarsia. En los dos últimos casos se trata de larvas de taxones hasta el momento monoespecíficos en la región paleárctica, pero al no haberse recolectado pupas o adultos no se puede asegurar la identificación específica.

Cianofícies i algues aerofítiques de substrats carbonatats.

Atmophytic Cyanophyta and Algae from limestone substrata. The walls of caves and tombs support an abundant colonization of light-dependent organisms. A total of 4 liverworts, 3 mosses, 7 lichens and 28 cyanophyta and algae are reported from 3 collecting sites. The development and specific composition of these organisms is related to microclimatic parameters. Opportunistic species present in soils are found on the mouth of hypogeal niches. Light attenuation allows the development of calcifying cyanophyta following a succesional pattern, each level having a different dominant species. Communities dominated by Scytonema julianum are replaced by Herpyzonema pulverulentum and, towards the less iluminated area, by Geitleria calcarea and Loriella sp. Key words: Caves, Light attenuation, Non vascular plants, Colonization, Calcifying cyanophyta, Scytonema julianum, Herpyzonema pulverulentum, Geitleria calcarea, Chlorophyta, Diatoms, Microclimatic gradient.

Ultrastructural study of the pit connections of Gelidiocolax Gardner (parasitic Rhodophyta)

A report on the ultrastructural observations of the pit connections in three species of Gelidiocolax (G. margarifoides (Martin and Pocock) Fan and Papenfus, G. christianae Feldmann and G. deformans Seoane-Carnba) has been carried out. As has been described in other species, electrondense elements and myelinic figures, possibly formed by the endoplasmic reticulum, were condensed in a mass. This mass became a diabolos-shaped structure before the cytoplasm had finished its division and the septum had reached its complete development. Myelinic figures were usually found in the core of well formed pit plugs, but such figures were apparently substituted by granular material during the ontogeny. Key words: Gelidiocolax ultrastructure, Pit connection, Pit connection ultrastructure, Pit connection Ontogeny.
