Authors: Zinchuk Mykola , Shevchuk Mykhailo , Zin’chuk Petro
Published: December 2019

Question of local inconsistencies of real soil cover versus theoretical data was raised in article. One of the reasons of inconsistencies is ignoring the problem of regional peculiarities of soil differences. The situation regarding the approaches to modern classification of soils in Ukraine, near abroad, as well as at the international level was analyzed. The active development of the classification of the models in the Eastern European countries was identified. The attention is focused on the future development of parametric approaches to classification of soils of Ukraine. Methodology of regional harmonization of soil cover of the Volhyn region by authentication of predominant soil types in the modern classification and International reference base for soil resources was proposed. Periodic monitoring of state of classification areas of soils for regional harmonization of criteria for the diagnosis of soil differences, the activation of the local soil science cells for assessment of the compliance levels of scientific developments in the classification and improvement of the normative base for soil resources of Ukraine was recommended to carry out. Key words: soils, genetic classifications, parametric classifications, taxons, soil forming processes, KRAH, KPAH.

Published: December 2019

Background: Chronic Kidney Disease (CKD) is a progressive and irreversible kidney damage or dysfunction caused by the body's failure to maintain metabolism, fluid and electrolyte balance. Most of the CKD in Indonesia is diagnosed an advanced and late stage, so dialysis is necessary to solve this problem. The most common complaints of hemodialysis patients are muscle weakness. Patients with muscle weakness are due to reduced activity, muscle atrophy, muscle myopathy, neuropathy or a combination of them. One way that can be done as muscle strengthening to support and protect the internal organs and tissues is to do physical exercise. Physical exercises include flexibility exercises, strengthening exercises, and cardiovascular exercises. The exercise was done by giving video education to the patient for 60-90 minutes and 2 sets at the time of hemodialysis. Video is one of the educational media so that patients easily understand and imitate the steps of physical exercise.

Objective: To know effectiveness of patient education with video to hemodialysis patient knowledge about physical activity exercise.

Methods: This study used quasi experimental method with one-group design pre-post test design.

Results: This research is a non parametric statistic test with Wilcoxon test method and got the result of 0.000 (p<0,05).

Conclusions: Video education can improve the knowledge of patients with chronic renal failure who run hemodialysis.

Avances en el estudio de biodeterioro asociado a presencia de líquenes en materiales arqueológicos líticos. La Primavera (Santa Cruz, Argentina).
Authors: Magnin Lucia Angelica , Lynch Virginia , Gracía Renato
Published: December 2019

Con el objetivo de indagar acerca del biodeterioro causado por líquenes creciendo sobre materiales arqueológicos líticos, en este trabajo preliminar se analizaron diferentes artefactos procedentes de la localidad La Primavera. La metodología de análisis incluye técnicas de observación de bajos y altos aumentos y análisis de EDAX. Se identifican los líquenes presentes y se observan las superficies de estos artefactos que constituyen soportes para su crecimiento. Se observó y analizó la diversidad de especies presentes y se reconocieron cuatro tipos de bioalteraciones asociadas (microperforaciones, desagregación superficial de la roca, microfracturaciones internas y microfracturaciones superficiales). Entre los morfotipos identificados, el que al parecer causa mayores daños es el crustoso endolítico, seguido del folioso. Estas bioalteraciones dificultan la observación de los caracteres tecnológicos principales, así como estudios específicos acerca de la funcionalidad del instrumental lítico, lo que produce pérdida de información. Conocer más detalladamente cómo estas bioalteraciones afectan a estos materiales es relevante para las interpretaciones arqueológicas. Por lo tanto, este trabajo es una importante contribución al estudio de biodeterioro sobre artefactos líticos que hasta el momento no ha sido objeto de investigaciones específicas

Authors: Salgado Salomón María Eugenia , Barroetaveña Carolina , Pildain María Belen , Kuhar Francisco , Rajchenberg Mario
Published: December 2019

La presencia de especies de Tomentella ha sido reportada abundantemente en bosques templados, tropicales y regiones circumpolares. Las especies del género Tomentella forman típicamente ectomicorrizas (EM) aunque también micorrizas orquioides, ericoides, monotroides y arbutoides. La descripción y caracterización de los morfotipos EM constituyen una herramienta muy útil en trabajos ecológicos. En este trabajo se presentan descripciones morfo-anatómicas de 4 EM de Tomentella asociadas a Nothofagus pumilio, N. dombeyi, N. antarctica, Lophozonia alpina y L. procera, identificadas molecularmente a nivel específico. La morfología y el tipo de exploración de las 4 EM fueron consistentes con lo reportado previamente para el género. Estas EM no presentaron especificidad por un único hospedante de Nothofagaceae. Nuestros resultados demuestran que el estudio morfo-anatómico de los morfotipos EM constituye una herramienta insustituible para la cuantificación y el análisis de la diversidad funcional de la comunidad EM.

Authors: Toledo Carolina Verónica , Barroetaveña Carolina
Published: December 2019

Los bosques de Nothofagus spp. de la Patagonia Argentina albergan hongos con características organolépticas y nutricionales que las tornan atractivas para su consumo y plausibles de ser cultivadas sobre diferentes sustratos orgánicos. Se evaluaron los parámetros óptimos de crecimiento vegetativo de 7 especies de hongos silvestres comestibles potencialmente cultivables que pueden ser encontrados en estos bosques (Aleurodiscus vitellinus, Fistulina antarctica, F. endoxantha, Grifola gargal, Lepista nuda, Lycoperdon perlatum y Macrolepiota afín procera). Se obtuvieron 5 cepas de cada especie y se realizaron tres ensayos: 1) determinación de la temperatura óptima de crecimiento, 2) evaluación del crecimiento en diferentes medios de cultivo y caracterización miceliar de las cepas, y 3) evaluación del crecimiento de los micelios en granos. La temperatura óptima de crecimiento fue en general de 25 °C, aunque con rangos variables. El medio de cultivo más rápidamente colonizado fue el agar con papa y dextrosa. Lepista nuda y A. vitellinus mostraron las mayores tasas de crecimiento miceliar promedio tanto en medios como en granos. Las cepas de A. vitellinus, F. endoxantha y L. perlatum mostraron mayor heterogeneidad en la tasa de crecimiento en placas, mientras que las cepas de F. antarctica, G. gargal y M. afín procera mostraron comportamientos homogéneos.

Authors: Mangone Franco M , Catania Myriam Del V. , Albornoz Patricia L.
Published: December 2019

La familia Myrtaceae es una de las más numerosas en Argentina. En la provincia de Tucumán habitan 11 especies nativas, de las cuales Blepharocalyx salicifolius (Kunth) O. Berg, Eugenia uniflora L. y Myrcianthes pungens (O.Berg) D. Legrand presentan importancia medicinal, alimenticia y forestal. La información sobre las especies fúngicas y las modificaciones histológicas foliares que ellos producen es escasa. Por lo tanto, el objetivo de la presente investigación fue identificar las especies de hongos en hojas de las tres especies arbóreas y describir las modificaciones anatómicas causadas por la presencia de los mismos. Se trabajó con material fresco al que se aplicó técnicas y tinciones convencionales para su estudio. Se identificaron 12 especies fúngicas, 10 de ellas se citan por primera vez para la Argentina, en los tres hospedantes arbóreos estudiados. Puccinia psidii y Alternaria sp. se encontraron con mayor frecuencia. Los tejidos foliares más afectados fueron el parénquima esponjoso y el parénquima en empalizada. La lesión más significativa en la lámina foliar se observó en E. uniflora, producida por Microsphaerospis arundinis. Las especies fúngicas identificadas amplían el conocimiento de la diversidad de hongos asociados a hojas en especies arbóreas nativas de la provincia de Tucumán.

Authors: Vitali Maira S.
Published: December 2019

Debido a la gran importancia medicinal y alimentaria que tienen las hojas en especies de Smallanthus, como por ejemplo el mundialmente conocido “yacón” (Smallanthus sonchifolius), y que hasta el momento solo se han estudiado cuatro especies de las 23 que componen el género, se analizó aquí la anatomía foliar de todas las especies de Smallanthus. Se presenta también, una tabla de usos y nombres vulgares de las especies de las que se obtuvo tal información. Se realiza una descripción general de la anatomía foliar, incluyendo el pecíolo. Se identificaron tres tipos de tricomas: uno eglandular del tipo cónico simple y dos glandulares (biseriado capitado y biseriado vesiculado subtipo beta). Las especies de Smallanthus no mostraron diferencias en la anatomía de la lámina y del pecíolo. Se contabilizaron los canales secretores, de tipo esquizógeno, en casi todas las especies y se observó una tendencia al aumento del número de canales en las especies más australes.

Published: December 2019

La diversidad de polen atmosférico colectado mensualmente durante dos años (2011-2013) en trampas Tauber en tres sitios del Parque Nacional El Palmar (provincia de Entre Ríos) es usada para caracterizar la vegetación. El sitio 1 es un área mixta compuesta por pastizales, palmares y humedales. El sitio 2 es un área de pastizales y el sitio 3 un palmar denso. Se identificaron 71 tipos polínicos comprendidos en 43 familias procedentes de fuentes locales, regionales y extraregionales. Dieciséis tipos resultaron abundantes con más de 1% del Annual Pollen Influx en al menos dos muestras. Diferentes factores relacionados con los cambios cuali-cuatitativos de los taxa en el intervalo de estudio son considerados. Por lo tanto, la composición florística de cada sitio en comparación con sus asociaciones polínicas reveló que el sitio 2 se caracteriza por una alta abundancia de Asteraeceae-Asteroideae, con un aumento en el valor de Vernonia (Asteraceae Cichoroidea) y Lamiaceae durante el segundo año. Por otro lado, una composición palinológica similar (Asteraeceae-Asteroideae, Myrtaceae, Blepharocalyx salicifolius, Poaceae) se encuentra en los sitios 1 y 3, con tasas de variación entre ambos años. El sitio 3 se diferencia de los otros dos por el registro de Butia yatay en baja frecuencia en porcentajes similares en ambos años, en tanto que Adiantopsis chlorophylla y Microgramma mortoniana aumentaron durante el segundo año.

Authors: Medina Ricardo Daniel , Schaller Silvia Cristina , Dolce Natalia Raquel , Mroginski Luis Amado
Published: December 2019

En la bibliografía se citan numerosos trabajos de propagación in vitro de mandioca, sin embargo sólo se ha establecido la eficiencia de la multiplicación para un número muy restringido de cultivares y/o subcultivos durante la micropropagación. El objetivo de este trabajo fue evaluar la multiplicación in vitro de 20 cultivares de mandioca de interés económico para el Nordeste Argentino (6 subcultivos totales realizados cada 30 días). Para ello, se cultivaron segmentos uninodales en medio basal de Murashige y Skoog (1962) más 0,01 mg/L de ácido 1-naftalenacético, 0,01 mg/L de 6-bencilaminopurina y 0,1 mg/L de ácido giberélico. Todos los cultivares evaluados regeneraron plantas durante los 6 subcultivos. Independientemente del subcultivo, el número promedio de nudos regenerados por explante varió significativamente con el cultivar (P?0,0001), rondando valores de 2 a 5 nudos por planta. El número promedio de nudos acumulados fue significativamente distinto dependiendo del cultivar, alcanzando valores de 46 a 16.568 nudos totales por plantas (P?0,0001). Los resultados demuestran variabilidad debida al genotipo, distinguiéndose 3 grupos de cultivares en relación a su capacidad de propagación y crecimiento en longitud. La determinación de la tasa de multiplicación de distintos cultivares de mandioca es fundamental para la optimización de la micropropagación.

Published: December 2019

El crecimiento y la arquitectura de las especies leñosas que habitan los bosques inciden en la dinámica de estas comunidades. El objetivo principal de este estudio fue mejorar la comprensión de la dinámica de los cipresales patagónicos a partir del análisis del crecimiento longitudinal y de la arquitectura de las especies leñosas más abundantes en esas comunidades, las nativas: Aristotelia chilensis, Berberis microphylla, Lomatia hirsuta, Maytenus boaria, Myoschilos oblongum y Schinus patagonicus; y las exóticas: Juniperus communis, Prunus avium, Pseudotsuga menziesii y Rosa rubiginosa. El crecimiento longitudinal del eje principal no se relacionó necesariamente con el aumento en altura de las plantas durante el período de estudio (2012-14). Se registraron decrecimientos en altura en todas las especies excepto en P. menziesii y P. avium, exóticas para Patagonia. La mayoría de los individuos presentaron notables desviaciones de su eje principal de la vertical, las que se correlacionaron negativamente con la longitud del brote distal y con la variación en altura de las plantas. Se agruparon las especies en cuatro grupos funcionales, de acuerdo a su arquitectura y crecimiento. La invasión de los cipresales por parte de especies exóticas como P. menziesii y P. avium, asociadas a grupos funcionales distintos a los de las especies nativas más frecuentes, podría impactar significativamente en la dinámica de esas comunidades promoviendo el reemplazo de las especies nativas por las exóticas dominantes.
Diferencias en el hábito de crecimiento como variable explicativa de la influencia climática en Prosopis flexuosa en el Desierto del Monte Central (Argentina).
Authors: Piraino Sergio , Roig Juñent Fidel Alejandro
Published: December 2019

Los métodos dendroclimatológicos representan una de las herramientas más valiosas para analizar la influencia del clima sobre la dinámica del incremento radial y la morfología de las plantas leñosas. En el Desierto del Monte Central, Prosopis flexuosa DC (algarrobo dulce), crece como árbol uni-fustal pero también como multi-fustal. Investigaciones anteriores han evidenciado la utilidad del ancho de anillo de esta especie como registro de eventos climáticos. Sin embargo, estas investigaciones han diferido metodológicamente, considerando o descartando los individuos multi-fustales. Este trabajo analizó si la variabilidad en el hábito de crecimiento expresa diferencias en la señal dendroclimática del algarrobo dulce. Dos cronologías de ancho de anillos, una derivada de individuos uni-fustales (UF) y otra de multi-fustales (MF) presentes en un mismo ambiente ecológico fueron desarrolladas. Se observó que hay una mayor sensibilidad de la cronología MF respecto de la UF en relación a la incidencia en el crecimiento de eventos climáticos extremos y del clima en general en el largo plazo. Esto sugiere que los individuos multi-fustales constituyen una buena representación de la variabilidad del clima local. Debido a la gran extensión territorial de especie, otros estudios que abarquen la extensión geográfica de P. flexuosa son deseables para profundizar los resultados logrados.

En las hojas de caldén, Prosopis caldenia (Fabaceae), una especie aún no descripta de Rhopalomyia (Diptera: Cecidomyiidae) desarrolla agallas. Los objetivos de este estudio fueron describir exomorfológicamente la agalla inducida en los folíolos de la hoja de P. caldenia, diferenciar los estadios de desarrollo de la agalla y describir las modificaciones inducidas en los tejidos foliares agallados. Se colectaron hojas normales y con agallas entre febrero 2014 y noviembre 2015 en un fragmento de bosque de caldén ubicado en el área periurbana de Santa Rosa, La Pampa, Argentina. La morfología externa de la agalla se examinó mediante disección bajo microscopio estereoscópico. El examen de los tejidos foliares se realizó mediante preparados microscópicos temporarios y permanentes de cortes a mano alzada y con micrótomo respectivamente. La agalla está formada por la coalescencia parcial de dos folíolos contiguos acoplados generando una agalla bivalva con simetría bilateral, unicameral y conteniendo una larva del inductor. En la agalla se desarrolla un tejido nutritivo continuo que tapiza la superficie interna de la cámara larval y tejidos con función protectora y de sostén formados por células epidérmicas y parenquimáticas modificadas en esclereidas. La epidermis foliar es el tejido que experimenta los cambios más variados y profundos.

Authors: Yañez Agustina , Ponce Mónica
Published: December 2019

Se realiza un análisis morfológico de la familia de helechos Lindsaeaceae en la Argentina, y se actualizan los datos de su distribución. A partir de la rectificación de información previa debida a citas no corroboradas y erróneas determinaciones se confirma la presencia de un único taxón en el país: Lindsaea quadrangularis subsp. terminalis. Se provee una descripción morfológica detallada, consideraciones sobre el hábitat, notas relevantes, ilustraciones, fotografías y un mapa de distribución de la especie en el área de estudio. Se elabora una clave para identificar las especies del género Lindsaea para la Argentina y áreas limítrofes de Brasil.
Identificación de Leguminosae-Caesalpinioideae arbustivas-arbóreas y lianas de la selva Paranaense (Misiones, Argentina) utilizando caracteres vegetativos.
Authors: Kostlin Marcelo R.
Published: December 2019

En este trabajo se estudia la diversidad de caracteres morfológicos vegetativos de taxones nativos de la familia Leguminosae-Caesalpinioideae (en su sentido tradicional) de la Provincia de Misiones, Argentina, a fin de facilitar la identificación de géneros, especies, subespecies y variedades en ausencia de sus flores y frutos. Se estudiaron ejemplares de herbario de las 15 especies, subespecies y variedades de Caesalpinioideae arbustivas-arbóreas y lianas pertenecientes a 10 géneros presentes en Misiones. Los caracteres analizados fueron hábito, filotaxis, tallo, hojas, estípulas, glándulas y nectarios extraflorales, tipo de venación, pubescencia y yemas. Como resultado se presenta una clave para la identificación de todos los taxones estudiados y descripciones de sus caracteres vegetativos. A su vez se discute la variabilidad observada en los caracteres vegetativos, así como observaciones sobre distribución, hábitat y fenología. Además, se proporciona una clave vegetativa de subfamilias de Leguminosae arbustivas-arbóreas y lianas presentes en la selva Paranaense de Misiones para facilitar la identificación de las Caesalpinioideae. En resumen, estas claves serán cruciales para una identificación precisa de la subfamilia de Caesalpinioideae y sus especies, en las estaciones en que sus flores y frutos están ausentes.

Authors: Aldoghachi Asraa Faris , Cheah Pike-See , Ibrahim Normala , Lye Munn Sann , Ling King-Hwa
Published: November 2019

Major depressive disorder (MDD) is a serious mental illness with a multifactorial aetiology that was shown to influence behaviour and affect cognition. Previous research has favoured the involvement of dopamine in the aetiology of the disorder, and since one of the critical regulators of the dopamine levels and activity in the brain is DAT1, the present study investigated the association of a single nucleotide polymorphism in the DAT1 gene (rs40184) and MDD in the Malaysian population. A total of 300 cases and 300 matched controls were recruited from four Klang valley hospitals and were screened for DAT1 rs40184 using high resolution melting assays. The allele and genotype frequencies were analysed by using Chi-square. Hardy Weinberg equilibrium for the distribution of alleles and genotypes was tested by using Chi-square. Determination of the association between rs40184 and MDD was achieved by conditional logistic regression using SPSS. In the present study, no significant association was obtained between DAT1 and MDD in the Malaysian population.
Administration and Management in Institutions of Higher Education in the Kingdom SHS (Based on the Example of Universities in Belgrade and Zagreb)
Authors: Bajagić Dušan
Published: December 2019

The method of quantitative and qualitative analysis of primary documents (laws and by-laws) made it possible to study the administration and nature of the management of institutions of higher education under the jurisdiction of the Ministry of Education. This is the University of Belgrade (BU), as well as the University (ZU) and the high schools in Zagreb. The findings of the survey confirmed that, in the context of the pluralism of legal systems that remained in the Kingdom SHS (KSHS), these two centers of higher education, each of which had special autonomous rights, were different administrative systems. BU as a whole was formed and developed in the period before WWI. At the same time, in the KSHS more attention was paid to the creation and development of individual faculties. So, BU took the form of an autonomous, integrated and self-sufficient administrative system, which independently chose its own authorities and carried out all the tasks before it. ZU consisting of three faculties had been developing for half a century in Austria-Hungary. In accordance with the territorial and political autonomy of the region, Croatia and Slavonia ZU embodied the model of territorial-functional administrative system. It was governed by the political power – the land government / regional administration, as well as the ban / regional governor. Their interrelated and interdependent authorities covered most of the cases and tasks that accompanied the work of the memory and higher schools. Within the framework of the KSHS, in just over six years, ZU, which grew out as a result of the opening of three new faculties and three higher schools, became an autonomous system of management.
Pedido de ajuda em vítimas de violência no namoro: Revisão sistemática
Authors: Pinheiro Inês , Caridade Sónia Maria Martins
Published: December 2019

Objetivo: Este estudo tem como objetivo sistematizar o conhecimento produzido sobre o pedido de ajuda em adolescentes e jovens adultos que experienciaram violência no namoro, através da identificação e análise dos estudos empíricos realizados neste âmbito. Métodos: Para tal adotámos os procedimentos para a realização de uma revisão sistemática dos estudos centrados nos comportamentos de pedido de ajuda em vítimas de violência no namoro. Resultados: Foram identificados 18 estudos com enfoque nos comportamentos de pedido de ajuda por parte dos/as adolescentes e jovens adultos vítimas de violência no namoro. A grande maioria dos estudos constatou que as vítimas revelam uma preferência pelo recurso a fontes de revelação informais, privilegiando os pares. As vítimas de sexo feminino surgiram como as que demonstraram uma maior tendência para a revelação do abuso íntimo, surgindo ainda como as expectadoras que prestam mais suporte e apoio às vítimas. Foram, ainda, identificadas múltiplas barreiras à revelação da experiência abusiva por parte dos/as participantes (e.g., legitimação da violência, medo de perder o/a parceiro/a, vergonha e autossuficiência para resolver a situação). Conclusões: Consideramos que a investigação neste domínio deverá procurar incluir outras amostras, estudos de continuidade, beneficiando de uma maior uniformização no tipo de instrumentos usados para efetuar a recolha de dados.

Authors: Mendes José , Sousa Mónica , Leite Vânia Margarida , Bettencourt da Silva Belchior Nuno Miguel , Pires Medeiros Maria Teresa
Published: December 2019

Objetivos: O sono ao demonstrar-se fundamental para o desenvolvimento do indivíduo, despertando o interesse em investigar qualidade do sono em estudantes do ensino superior. Assim, pretendeu-se com o presente estudo, caracterizar as componentes da qualidade subjetiva do sono e sonolência excessiva diurna numa amostra de estudantes do ensino superior. Método: Aplicaram-se as versões portuguesas do Índice da qualidade do sono (PSQI-PT) e da Escala de Sonolência excessiva diurna (ESS), em 257 estudantes do ensino superior distribuídos por sete instituições de ensino superior. Resultados: A maioria dos participantes revelou subjetivamente uma má qualidade do sono e referiu dormir mais de sete horas durante a semana, sendo este número maior durante o fim de semana. A perceção da Latência do Sono e da Disfunção Durante o Dia diferiu em função do sexo dos participantes. Os trabalhadores-estudantes mostraram percecionar uma fraca Qualidade Subjetiva do Sono e uma menor Duração do Sono. Encontrou-se uma correlação baixa com significância estatística entre o PSQI-PT e a ESS. Apesar da maioria dos participantes da amostra percecionar uma má qualidade do sono, também a maioria revelou uma eficiência subjetiva do sono superior a 85,0%. Conclusões: Verificou-se que os participantes em estudo avaliaram subjetivamente a qualidade do sono como sendo pobre. Estudos futuros devem explorar possíveis programas de prevenção (i.e., alimentação, TIC, exercício físico) que melhorem a qualidade subjetiva do sono.
Desfiguramento facial em contexto pediátrico: Revisão integrativa da literatura
Authors: Mendes José , Alcaidinho Durval , Alcaidinho Maura , Silva Sara
Published: December 2019

Contexto e Objetivo: O desfiguramento facial revela-se um problema quando afeta a criança/adolescente e respetivos familiares. No entanto, apesar de o principal objetivo dos enfermeiros se focar qualidade dos cuidados de saúde, a maioria dos profissionais de saúde carece de competências no cuidado de crianças/jovens com desfiguramento facial. Desconhecidos estudos em Portugal, desenvolveu-se uma análise da literatura com o objetivo de apresentar resultados de investigação e contribuir com reflexões sobre a realização de futuros estudos da contribuição do enfermeiro perante o desfiguramento facial em crianças/jovens. Métodos: Com recurso à plataforma MeSH, validaram-se os descritores: Desfiguramento Facial; Enfermeiros; Emoções, Criança/adolescente e Pediatria; tendo-se procedido à realização de uma pesquisa individual nas bases de dados: CINAHL®; Medline; Nursing & Allied Health Collection; Cochrane Plus Collection; Cochrane Database of Systematic Reviews e MedicLatina, através dos operadores booleanos AND e NOT. Resultados: Num total de 92 publicações, considerando-se 22 duplicadas e 66 publicações não cumpriam os critérios de inclusão, considerando-se somente quatro publicações elegíveis. Discussão e Conclusões: As lesões na cabeça são consideradas as principais causas de mortalidade (trauma) e a Fissura do Lábio Palatino é o desfiguramento congénito mais comum. Contudo ambas afetam a qualidade de vida e a identidade da criança/jovem comprometendo o desenvolvimento biopsicossocial. Os enfermeiros, considerados como profissionais de primeira linha, deverão estar capacitados para aconselhar, apoiar, informar e colaborar com a equipa multidisciplinar, capacitando os pais de estratégias que permitam o acesso ao apoio emocional perante o desfiguramento facial e promovendo uma imagem corporal positiva como componente crítica do cuidar.
Efeitos da vergonha em sintomas depressivos em pessoas com e sem doença física crónica: Os papéis mediadores da autocompaixão e da ação comprometida
Authors: Veiga Daniela , Trindade Inês , Ferreira Cláudia
Published: December 2019

Objetivo: O presente estudo teve como objetivo testar o potencial efeito mediador da autocompaixão e da ação comprometida na relação entre vergonha e sintomatologia depressiva, em pessoas sem e com diagnóstico de doença física crónica. Adicionalmente, foram exploradas as diferenças em relação a essas variáveis entre os dois grupos. Métodos: A amostra foi constituída por 453 participantes (223 com e 230 sem diagnóstico de doença física crónica), os quais responderam numa plataforma online a um protocolo de medidas de autorrelato de vergonha, autocompaixão, ação comprometida e sintomas depressivos. Resultados: Os participantes com diagnóstico de doença crónica apresentaram níveis significativamente (p < 0,05) superiores de vergonha e sintomatologia depressiva, e níveis inferiores de ação comprometida, comparativamente aos participantes sem doença física crónica. Contudo, não foram encontradas diferenças significativas entre os dois grupos relativamente às competências autocompassivas. As análises de correlação revelaram que a vergonha se associa negativamente à autocompaixão e ação comprometida e positivamente á sintomatologia depressiva, tanto no grupo sem como no grupo com diagnóstico de doença física crónica. Os resultados da path analysis indicaram que sentimentos de vergonha têm um impacto significativo, explicando 41% da variância da sintomatologia depressiva, parcialmente via menores níveis de autocompaixão e de ação comprometida. Os resultados da análise multigrupos demonstraram que o modelo testado é plausível nos dois grupos em estudo. Conclusões: Este estudo parece fornecer importantes contributos para a compreensão do impacto protetor das competências autocompassivas e da adoção de ações comprometidas para a saúde mental, tanto para pessoas sem como com diagnóstico de doença física crónica. De facto, os resultados sugerem que estes processos de regulação emocional são importantes mecanismos mediadores da relação entre vergonha e sintomas depressivos. Finalmente, estes dados parecem suportar o desenvolvimento de abordagens mais eficazes para a promoção da saúde psicológica para pessoas sem e com doença crónica.
