Decompressive hemicraniectomy following malignant middle cerebral artery infarctions:a mixed methods exploration of carer experience and level of burden

Purpose: This study explores the experiences and sense of burden of family carers of survivors of malignant middle cerebral artery infarctions who had undergone decompressive hemicraniectomy. To date, there have been no studies examining carer outcomes among this unique population. This study, taken alongside an already published study of survivor outcomes, provides a more holistic picture with regard to sequelae within the sample. Method: Six family carers completed the Sense of Competence Questionnaire and the Hospital Anxiety and Depression Scale. These results were compared with existing normative data. Carers also consented to a semi-structured interview. Interview data were examined using thematic content analysis. Consistent with the mixed methods design, quantitative and qualitative findings were integrated for further analysis. Results: While carers experienced many losses, their overall sense of burden was not outside 'Average' limits, nor did they experience clinically significant symptoms of depression. All carers identified methods of coping with the demands of caregiving. These included intrapersonal, interpersonal and practical strategies. All carers apart from one were able to identify areas of post-traumatic growth. Conclusion: Carers will benefit from information, support and care. In addition, problem solving skills are essential in managing the myriad difficulties that arise in the aftermath of stroke. [Box: see text].

Localised gamma irradiation and experimental intraocular proliferation

A controlled study was undertaken to assess the effect of gamma irradiation on post-traumatic intraocular cellular proliferation. A standard perforating injury in the posterior segment of the rabbit eye was used to induce intraocular cellular proliferation and vitreo-retinal membrane formation. The site of injury was irradiated with an ophthalmic Cobalt60 applicator which provided a continuous source of gamma rays. Non-irradiated eyes developed traction retinal detachments associated with post-traumatic vitreo-retinal membranes. Irradiated eyes developed attenuated membranes or atrophic retinal scars, with the retina remaining attached. The membranes in non-irradiated eyes were highly cellular with abundant collagen, while irradiated membranes had fewer cells within a sparse collagen matrix. The episcleral fibroblasts, on autoradiographic studies appeared to be the main source of the cells that formed the proliferating tissue in both non-irradiated and irradiated eyes. In irradiated eyes both the inflammatory response and division of fibroblasts were delayed and reduced.

Does vicarious traumatisation affect oncology nurses?:A literature review

It is widely documented that nurses experience work-related stress [Quine, L., 1998. Effects of stress in an NHS trust: a study. Nursing Standard 13 (3), 36-41; Charnley, E., 1999. Occupational stress in the newly qualified staff nurse. Nursing Standard 13 (29), 32-37; McGrath, A., Reid, N., Boore, J., 2003. Occupational stress in nursing. International Journal of Nursing Studies 40, 555-565; McVicar, A., 2003. Workplace stress in nursing: a literature review. Journal of Advanced Nursing 44 (6), 633-642; Bruneau, B., Ellison, G., 2004. Palliative care stress in a UK community hospital: evaluation of a stress-reduction programme. International Journal of Palliative Nursing 10 (6), 296-304; Jenkins, R., Elliott, P., 2004. Stressors, burnout and social support: nurses in acute mental health settings. Journal of Advanced Nursing 48 (6), 622-631], with cancer nursing being identified as a particularly stressful occupation [Hinds, P.S., Sanders, C.B., Srivastava, D.K., Hickey, S., Jayawardene, D., Milligan, M., Olsen, M.S., Puckett, P., Quargnenti, A., Randall, E.A., Tyc, V., 1998. Testing the stress-response sequence model in paediatric oncology nursing. Journal of Advanced Nursing 28 (5), 1146-1157; Barnard, D., Street, A., Love, A.W., 2006. Relationships between stressors, work supports and burnout among cancer nurses. Cancer Nursing 29 (4), 338-345]. Terminologies used to capture this stress are burnout [Pines, A.M., and Aronson, E., 1988. Career Burnout: Causes and Cures. Free Press, New York], compassion stress [Figley, C.R., 1995. Compassion Fatigue. Brunner/Mazel, New York], emotional contagion [Miller, K.I., Stiff, J.B., Ellis, B.H., 1988. Communication and empathy as precursors to burnout among human service workers. Communication Monographs 55 (9), 336-341] or simply the cost of caring (Figley, 1995). However, in the mental health field such as psychology and counselling, there is terminology used to captivate this impact, vicarious traumatisation. Vicarious traumatisation is a process through which the therapist's inner experience is negatively transformed through empathic engagement with client's traumatic material [Pearlman, L.A., Saakvitne, K.W., 1995a. Treating therapists with vicarious traumatization and secondary traumatic stress disorders. In: Figley, C.R. (Ed.), Compassion Fatigue: Coping with Secondary Traumatic Stress Disorder in Those Who Treat the Traumatized. Brunner/Mazel, New York, pp. 150-177]. Trauma not only affects individuals who are primarily present, but also those with whom they discuss their experience. If an individual has been traumatised as a result of a cancer diagnosis and shares this impact with oncology nurses, there could be a risk of vicarious traumatisation in this population. However, although Thompson [2003. Vicarious traumatisation: do we adequately support traumatised staff? The Journal of Cognitive Rehabilitation 24-25] suggests that vicarious traumatisation is a broad term used for workers from any profession, it has not yet been empirically determined if oncology nurses experience vicarious traumatisation. This purpose of this paper is to introduce the concept of vicarious traumatisation and argue that it should be explored in oncology nursing. The review will highlight that empirical research in vicarious traumatisation is largely limited to the mental health professions, with a strong recommendation for the need to empirically determine whether this concept exists in oncology nursing.

Resilience and Burnout in Child protection social work: Individual and organisational themes from a systematic literature review

Child protection social work is acknowledged as a very stressful occupation, with high turnover and poor retention of staff being a major concern. This paper highlights themes that emerged from findings of sixty-five articles that were included as part of a systematic literature review. The review focused on the evaluation of research findings, which considered individual and organisational factors associated with resilience or burnout in child protection social work staff. The results identified a range of individual and organisational themes for staff in child protection social work. Nine themes were identified in total. These are categorised under ‘Individual’ and ‘Organisational’ themes. Themes categorised as individual included personal history of maltreatment, training and preparation for child welfare, coping, secondary traumatic stress, compassion fatigue and compassion satisfaction. Those classified as organisational included workload, social support and supervision, organisational culture and climate, organisational and professional commitment, and job satisfaction or dissatisfaction. The range of factors is discussed with recommendations and areas for future research are highlighted.

A terapia de grupo na doença oncológica

Existem milhões de sobreviventes de cancro da mama no mundo, em exponencial crescimento. Esta população pode apresentar preocupações relevantes acerca do futuro, depressão, ansiedade, sintomas pós-traumáticos, e comprometimento da qualidade de vida. As intervenções de grupo breves, estruturadas, especialmente as que incluem estratégias cognitivo-comportamentais, têm sido indicadas para esta população. O presente trabalho surge neste contexto, em que os estudos são escassos, especialmente em Portugal. Um conjunto de 5 estudos foi conduzido com o intuito de avaliar a eficácia de dois programas de intervenção de grupo breves e estruturadas de inspiração cognitivo-comportamental, um de tipo psicopedagógico e outro de terapia cognitivo-comportamental, em sobreviventes de cancro da mama. Nos primeiros dois estudos procedeu-se ao estudo das caraterísticas psicométricas de dois instrumentos de avaliação, o Questionário de Formas de Lidar com o Cancro (CCQ) e o Questionário de Saúde do Paciente (PHQ-9).Os dois estudos seguintes referem-se ao desenvolvimento dos programas de intervenção de grupo, acompanhados dos resultados preliminares. No último estudo avaliou-se a eficácia dos dois programas de intervenção na promoção do ajustamento psicossocial de 62 sobreviventes de cancro da mama, num estudo quasi-experimental, com pré e pós-testes e duas avaliações de seguimento (3 e 6 meses após a intervenção). Foram utilizados os seguintes instrumentos de avaliação: o CCQ; o PHQ-9; a Escala de Controlo Emocional (CEC); a Escala de Ansiedade e Depressão Hospitalar (EADH); o questionário de qualidade de vida da Organização Europeia de Investigação e Tratamento de Cancro com o módulo suplementar de cancro da mama (EORTC QLQ-C30 e BR-23); o Inventário Clínico de Autoconceito (ICAC); o Teste de Orientação de Vida - Revisto (TOV-R); o Perfil dos Estados de Humor (POMS); a Subescala de Crescimento Pessoal da Escala de Bem-Estar Psicológico (EBEP); a sub-escala de espiritualidade e o Inventário de estado-traço de ansiedade (STAI). Resultados: As sobreviventes que não tiveram intervenção apresentaram deterioração de dois domínios da qualidade de vida, a função cognitiva e a dor, para além de piores resultados na subescala de vigor. A deterioração dos domínios da qualidade de vida manteve-se aos 3 meses e extendeu-se aos sintomas da mama, o que não se verificou com o vigor. O grupo com intervenção psicoeducativa apresentou melhoria do autoconceito até aos 6 meses. Neste grupo também se observou um aumento do controlo emocional até aos 3 meses. O grupo de terapia cognitivo-comportamental apresentou aumento do estado de ansiedade e diminuição do funcionamento de papel no final da intervenção, diminuição do funcionamento emocional aos 3 meses e aumento na hostilidade e na confusão aos 6 meses. Ambos os grupos com intervenção apresentaram diminuição do traço de ansiedade aos 6 meses. Foram encontradas diversas correlações significativas destes efeitos com variáveis demográficas, clínicas e psicossociais. Conclusão: As intervenções de grupo breves, de inspiração cognitivo-comportamental, mostraram contribuir para a redução do traço de ansiedade a longo prazo e para a manutenção da função cognitiva, da dor, do vigor, e dos sintomas da mama nas sobreviventes. O programa psicopedagógico parece ser mais indicado para as sobreviventes, pelos efeitos no autoconceito, com maior extensão a longo prazo. São referidas implicações para a prática clínica e para a promoção da saúde mental desta população.

Les victimisations et les conséquences de la traite et l’esclavage négriers transatlantique selon les Afro-descendants

La traite et l’esclavage négriers transatlantique n’ont jamais été étudiés d’un point de vue criminologique. En fait, à part l’histoire, peu de disciplines des sciences sociales et humaines se sont intéressées aux évènements qui constituent la traite et l’esclavage négriers transatlantique. Toutefois, de récentes recherches commencent à se pencher sur les séquelles résultant des multiples victimisations (agressions physiques et psychologiques) subies par les Noirs durant la traite et l’esclavage négriers transatlantique. Nous postulons que la criminologie peut également contribuer à une meilleure compréhension de ces évènements. Ainsi, cette étude vise à sonder les perceptions des Afro-descendants sur les victimisations et les conséquences de la traite et de l’esclavage négriers transatlantique. L’analyse des entretiens réalisés démontrent clairement que la traite et l’esclavage négriers transatlantique n’appartiennent pas seulement au passé. Au contraire, la traite et l’esclavage négriers transatlantique restent présents dans les esprits et les cœurs. Ils sont surtout perçus comme une source de victimisations actuelles touchant la communauté africaine et antillaise tels que la faible confiance en soi, la faible estime de soi, la hiérarchie de la couleur, le racisme interne…Aussi, tous les répondants plaident pour au moins une forme de réparation (pécuniaire et monétaire, éthique ou politique, historique, éducative, psychologique, diplomatique) des conséquences de la traite et l’esclavage négriers transatlantique. Les entrevues mettent également en évidence une division dans les représentations basées sur la version (fonctionnaliste ou intentionnaliste) de cette histoire, ainsi que des différences de représentations selon le groupe ethnique d’appartenance (Africain ou Antillais).

Les cytokines inflammatoires modulent la prolifération et la différenciation in vitro des cellules souches/progénitrices de la moelle épinière.

La moelle épinière (MÉ) est essentielle pour relier les informations motrices et sensorielles entre le cerveau et la périphérie. Malheureusement, elle peut facilement être endommagée suite à un traumatisme médullaire (TM) ou des pathologies comme la sclérose en plaques. Chez les vertébrés inférieurs, tels les amphibiens, la MÉ lésée se régénère via ses cellules souches endogènes, alors que celle des mammifères démontre une très faible habileté régénératrice post-traumatique. Des travaux récents ont démontré que la MÉ des mammifères contient des cellules souches neurales latentes correspondant aux cellules épendymaires du canal central. D’autres études ont prouvé qu’à la suite d’un TM, les cellules souches épendymaires (cSÉ) prolifèrent, migrent vers le site de la lésion et se différencient principalement en cellules gliales. Promouvoir la régénération de la MÉ endommagée via la modulation des cellules souches endogènes devient donc une voie thérapeutique intéressante. Isolant des cellules souches/progénitrices de la MÉ via la culture de neurosphères (NS), nos études in vitro, en présence de cytokines inflammatoires ou de milieu conditionné auxmacrophages, suggèrent que la réponse inflammatoire influence fortement la prolifération et la différentiation des cSÉ. Dans l’objectif de définir le programme génétique relié à l’activation des cSÉ de la MÉ, nous avons débuté l’élaboration d’un protocole d’isolement des cSÉ à l’aide d’un modèle de souris transgénique.

Estudio Costo-Efectividad de Lidocaína tópica como adyuvante a Pregabalina y Gabapentina en dolor neuropático periférico en una I.P.S de Bogotá 2011.

Introducción: el dolor neuropático es una patología de considerable prevalencia e impacto socio-económico en la población latinoamericana, la evidencia clínica sugiere que los ligandos de canales de calcio y el parche de Lidocaína pueden tratar exitosamente el dolor neuropático periférico y localizado. Metodología: se realizo una evaluación económica tipo costo-efectividad, observacional y retrospectiva con datos extraídos de las historias clínicas de pacientes atendidos en la clínica de dolor de la IPS. La variable primaria de efectividad fue la mejoría del dolor medida mediante escala visual análoga. Resultados: se estudiaron 94 pacientes tratados con: Gabapentina (G) 21, Pregabalina (P) 24, Gabapentina+ lidocaína (G/P) 24, Pregabalina + Lidocaína (P/L) 25, los costos asociados al tratamiento son los siguientes COP$114.070.835, COP$105.855.920, COP$88.717.481 COP$89.854.712 respectivamente, el número de pacientes con mejoría significativa de dolor fue: 8,10,9 y 21 pacientes respectivamente. El ICER de G/L con respecto a G fue: COP$ -25.353.354. El ICER de P/L con respecto a P fue: COP$ -1.454.655. Conclusiones: la adición del parche de lidocaína a la terapia regular con P/L represento una disminución de consumo de recursos en salud como uso de medicamentos co-analgésicos, analgésicos de rescate y fármacos para controlar reacciones adversas, de la misma forma que consultas a profesionales de la salud. Cada paciente manejado con P/L representa un ahorro de COP $1.454.655 al contrario si se manejase con el anticonvulsivante de manera exclusiva, en el caso de G/L este ahorro es de COP $ 25.353.354 frente a G sola.

Child abuse: underlying mechanisms

Exposure to traumatic stress during childhood, in the form of abuse or neglect, is related to an increased vulnerability resulting in the development of several pathologies, this relation has been confi rmed by epidemiological studies; however, the neural mechanisms underlying such abnormalities are still unknown. Most of the research done has focused on the effects in the infant, and only recently it has begun to focus on the neurobiological changes in the abusive parents. In this article, I review some of the studies using animal models of early adverse trauma and present some of the data on neural changes. Further studies of brain abnormalities in abusive parents are still needed.

Las adicciones a la luz del psicoanálisis, una revisión de literatura

El presente trabajo de grado es una revisión de la literatura que permite hacer un recorrido desde el psicoanálisis acerca de la compleja problemática de las adicciones. Para ello, se revisaron las bases de datos PepWeb, Ebsco, y Jstor, revisando las posiciones del psicoanálisis freudiano, lacaniano y otras corrientes psicoanalíticas respondiendo a las siguientes preguntas de investigación: (a) ¿Cómo se comprenden las adicciones desde un marco de referencia psicoanalítico? (b) ¿Cómo –desde la teoría freudiana y la teoría lacaniana - se aborda la comprensión de la adicción? (c) ¿Qué dice el psicoanálisis contemporáneo sobre ésta problemática? Se abordan temas como la concepción de una adicción desde la perspectiva de Freud y Lacan hasta psicoanalistas contemporáneos, el rol que juega el goce en la adicción y, finalmente, el complejo debate incipiente sobre la legalidad del tóxico. Se encontró que es un campo de constante publicación y es necesario que los clínicos y los psicoanalistas aborden este campo de estudio clínico permanentemente y sigan produciendo investigaciones sobre el fenómeno.

Reduced heart rate responding to trauma reliving in trauma survivors with PTSD: correlates and consequences

The authors investigated whether heart rate (HR) responses to voluntary recall of trauma memories (a) are related to posttraumatic stress disorder (PTSD), and (b) predict recovery 6 months later. Sixty-two assault survivors completed a recall task modeled on imaginal reliving in the initial weeks postassault. Possible cognitive modulators of HR responsivity were assessed; dissociation, rumination, trauma memory disorganization. Individuals with PTSD showed a reduced HR response to reliving compared to those without PTSD, but reported greater distress. Notably, higher HR response but not self-reported distress during reliving predicted greater symptom reduction at follow-up in participants with PTSD. Engagement in rumination was the only cognitive factor that predicted lower HR response. The data are in contrast to studies using trauma reminders to trigger memories, which have found greater physiological reactivity in PTSD. The authors' observations are consistent with models of PTSD that highlight differences between cued or stimulus-driven retrieval and intentional trauma recall, and with E B. Foa and M.J. Kozak (1986) hypothesis that full activation of trauma memories facilitates emotional processing.

Are empathy and compassion bad for the professional social worker?

Recent studies have shown that social workers and other professional helpers who work with traumatized individuals run a risk of developing compassion fatigue or secondary traumatic stress. Some researchers have hypothesized that helpers do this as a result of feeling too much empathy or too much compassion for their clients, thereby implying that empathy and compassion may be bad for the professional social worker. This paper investigates these hypotheses. Based on a review of current research about empathy and compassion it is argued that these states are not the causes of compassion fatigue. Hence, it is argued that empathy and compassion are not bad for the professional social worker in the sense that too much of one or the other will lead to compassion fatigue.

Resolution of a titanium implant fracture after a recurrent trauma

Post-traumatic complications occasionally lead to tooth loss as well as the need for future implants. However, rehabilitation with endosseous osseointegrated implants does not protect the patient from the risk of suffering a new trauma. Implant fracture and the damage of the hexagon are post-traumatic complications that guide the clinician to preparing a more intricate treatment plan. The authors present a clinical case of a recurrent trauma of maxillary implant fracture. The treatment plan was to remove the implants followed by autogenous bone grafting to correct the defect. Two titanium implants were replaced, followed by connective tissue graft after allowing complete the healing process of the bone graft to occur. In the postoperative period of 6 months, satisfactory results have been shown as regards soft and hard tissues wound healing.
