Abstract: Objectives. To explore the coping strategies used following a lower limb amputation and their relationship to adjustment in the hospital, rehabilitation, and home setting. Method. Sixteen individuals who had a lower limb amputation due to vascular disease completed questionnaires, including the Ways of Coping Questionnaire (WCQ), during hospitalization (T1), at the end of rehabilitation (T2), and 2-3 months after discharge from rehabilitation (T3). A subsample ( ) also participated in three semistructured interviews analyzed using the approach of Miles and Huberman. Results. Self-controlling was the coping strategy used most, followed by seeking social support and positive reappraisal. Three additional coping strategies not found in the WCQ were identified in the qualitative data: noticing progress, learning new things, and using humor. Confrontive coping (T1) and escape-avoidance (T1, T2, and T3) were related to adjustment problems while positive reappraisal (T1 and T3), seeking social support (T1 and T3), and planful problem solving (T3) were associated with positive adjustment. Conclusion. Coping strategies used to deal with the amputation seem to vary across settings, thus signifying the complexity of the coping process following a lower limb amputation due to vascular disease. 1. Introduction Following a lower limb amputation, many individuals face stressful situations such as phantom pain [1], loss of functional independence [2], and body image issues [3]. The coping abilities of individuals who had an amputation are greatly utilized and some may be overwhelmed by the task at hand. In fact, 15 to 42% of them develop depressive symptoms [4–9]. When facing a stressful situation, people react by using coping strategies, that is, they engage in multiple behavioral and cognitive efforts to regain or maintain their well-being [10]. Adjustment is the result of using various coping strategies to deal with the different stressful aspects of a situation, in this case, an amputation. Coping strategies targeting emotions caused by a stressful event (emotion-focused strategies) have been found to be related to psychosocial and functional adjustment following a lower limb amputation. A study by Hill et al. [11] revealed that the combination of three coping strategies, namely, catastrophizing, increase in behavioral activities and hoping/praying, accounted for a statistically significant proportion of functional ( ; ) and psychosocial ( ; ) adjustmentproblems even after controlling for demographic and amputation-related variables. Catastrophizing alone was a

Abstract: We recently developed a new hindlimb immobilization procedure that induces significant skeletal muscle atrophy and used it to show that an inflammatory process characterized by the up-regulation of TNFα, a known activator of the canonical NFκB pathway, is associated with the atrophy. Here, we used this model to investigate the effect of in vivo proteasome inhibition on the muscle integrity by histological approach. TNFα, IL-1, IL-6, MuRF-1 and Atrogin/MAFbx mRNA level were determined by qPCR. Also, a functional measurement of locomotors activity was performed to determine if the treatment can shorten the rehabilitation period following immobilization.In the present study, we showed that the proteasome inhibitor MG132 significantly inhibited IκBα degradation thus preventing NFκB activation in vitro. MG132 preserved muscle and myofiber cross-sectional area by downregulating the muscle-specific ubiquitin ligases atrogin-1/MAFbx and MuRF-1 mRNA in vivo. This effect resulted in a diminished rehabilitation period.These finding demonstrate that proteasome inhibitors show potential for the development of pharmacological therapies to prevent muscle atrophy and thus favor muscle rehabilitation.Skeletal muscle atrophy may be caused by prolonged immobilization, which has a significant impact on the duration and intensity of rehabilitation [1]. It is characterized by increased muscle fatigability associated with changes in muscle fiber size, reduced muscle protein synthesis [2], and enhanced muscle protein ubiquitination and degradation [3,4]. The pro-inflammatory cytokine TNFα has been reported to be involved in the process of muscle wasting by causing myofibrillar protein degradation via the ubiquitin proteasome pathway [5]. By activating transcription factor NFκB, TNFα plays a central role in regulating muscle protein catabolism in vitro and in vivo [6-8]. Mourkioti et al. have shown that muscle genetically depleted of NFκB exhibits increased strength, diminished protein degr

BMC Health Services Research , 2008, DOI: 10.1186/1472-6963-8-177
Abstract: The qualitative design chosen is a fourth generation evaluation combined with case studies. A home care team of a health and social services center situated in the Eastern Townships (Québec, Canada) will be involved at every step in the study. A sample will be formed of 15 health care professionals and 30 of their home care clients and caregiver. Semi-structured interviews, observations of home care interventions and socio-demographic questionnaires will be used to collect the data. Nine instruments used by the team in prior studies will be adapted and reviewed. A personal log will document the observers' perspectives in order to foster objectivity and the focus on the intervention. The in-depth qualitative analysis of the data will illustrate profiles of enabling interventions and individual empowerment.The ongoing process to transform the health care and social services network creates a growing need to examine intervention practices of health care professionals working with clients receiving home care services. This study will provide the opportunity to examine how the intervention process plays out in real-life situations and how health care professionals, clients and caregivers experience it. The intervention process and individual empowerment examined in this study will enhance the growing body of knowledge about empowerment.This study is part of a process to transform health care practices with the aim of strengthening empowerment of clients with chronic health problems. To achieve this objective, an in-depth analysis of home care interventions will be undertaken using an evolving model of empowerment interventions (enabling interventions). The intervention indicators were derived from the findings of previous studies [1-6].This study is concept-oriented and empirical in nature and will help to further refine interventions supporting empowerment. It is in line with the reform of the Québec health care system that calls for a transition of services from health
As rela??es entre saber e poder em testes psicodiagnósticos a partir de M. Foucault

DELTA: Documenta??o de Estudos em Lingüística Teórica e Aplicada , 2005, DOI: 10.1590/S0102-44502005000200003
Abstract: in this article my main objective is to approach some questions related to the tests used in psychodiagnostics processes of children who are considered as having learning difficulties. having the book discipline and punish (1975/1986) by foucault as theoretical basis, i intend to investigate the hypothesis that the child is considered ill or abnormal due to the factors related to imposed norms and not to organic aspects and/or neurological pathology. my interest is to analyse the signs that allow us to point out the written language conception of tests. this language is expected and privileged, however it may not be the language that the child uses and experiences every day.
Etiology and immunology of infectious bronchitis virus
Caron, LF;
Revista Brasileira de Ciência Avícola , 2010, DOI: 10.1590/S1516-635X2010000200007
Abstract: infectious bronchitis virus (ibv) of chickens is currently one of the main diseases associated with respiratory syndrome in domestic poultry, as well as with losses related to egg production. the etiological agent is a coronavirus, which presents structural differences in the field, mainly in the s1 spike protein. the immune response against this virus is complicated by the few similarities among serotypes. environmental and management factors, as well as the high mutation rate of the virus, render it difficult to control the disease and compromise the efficacy of the available vaccines. bird immune system capacity to respond to challenges depend on the integrity of the mucosae, as an innate compartment, and on the generation of humoral and cell-mediated adaptive responses, and may affect the health status of breeding stocks in the medium run. vaccination of day-old chicks in the hatchery on aims at eliciting immune responses, particularly cell-mediated responses that are essential when birds are first challenged. humoral response (igy and iga) are also important for virus clearance in subsequent challenges. the presence of antibodies against the s1 spike protein in 3- to 4-week-old birds is important both in broilers and for immunological memory in layers and breeders.
