Première phase d’un programme de recherche sur l’utilisation de vasopresseurs en traumatologie : étude observationnelle et revue systématique

Résumé : Les réanimateurs ont recours à des interventions à la fois médicales et chirurgicales en contexte de choc traumatique. Le rôle des vasopresseurs dans cette prise en charge est controversé. Alors que les lignes directrices américaines considèrent que les vasopresseurs sont contre-indiqués, certains experts européens en encouragent l’utilisation pour diminuer le recours aux liquides intraveineux. Avant d’élaborer un essai clinique, il importe de comprendre la pratique actuelle à laquelle se comparera une intervention expérimentale, ainsi que de connaître le niveau d’incertitude dans la littérature entourant la question de recherche. Le Chapitre 2 de ce travail présente une étude observationnelle effectuée dans un centre régional de traumatologie québécois. Cette étude documente les pratiques de réanimation adoptées par les équipes de traumatologie en 2013, particulièrement le recours aux liquides intraveineux et aux vasopresseurs. Les résultats démontrent que les vasopresseurs ont été utilisés chez plus de 40% des patients, particulièrement les victimes de traumatismes crâniens (RC 10.2, IC 95% 2.7-38.5). De plus, les vasopresseurs ont été administrés dans les phases précoces de la réanimation, soit avant l’administration d’un volume important de liquides. Le Chapitre 3 présente une revue systématique portant sur l’utilisation précoce de vasopresseurs en traumatologie. Les bases de données MEDLINE, EMBASE, CENTRAL et ClinicalTrials.gov ont été interrogées, ainsi que les abrégés présentés dans les conférences majeures en traumatologie depuis 2005. La sélection des études et l’extraction des données ont été effectuées en duplicata. Aucune donnée interprétable n’a pu être extraite des études observationnelles et le seul essai clinique identifié n’avait pas une puissance suffisante (RR de mortalité avec vasopresseurs 1.24, IC 95 % 0.64-2.43). Cette synthèse met en lumière l’incertitude scientifique sur le rôle des vasopresseurs en traumatologie. Les vasopresseurs ont des bénéfices potentiels importants, puisqu’ils permettent entre autres de supporter étroitement l’hémodynamie des patients. En revanche, ils présentent aussi un fort potentiel de dangerosité. Ils sont utilisés fréquemment, malgré l’absence de données sur leurs risques et bénéfices. Ces trouvailles établissent clairement la pertinence clinique et le bien-fondé éthique d’un essai clinique sur le rôle des vasopresseurs dans la prise en charge précoce des victimes de traumatismes.

A systematic review of the cost-effectiveness of targeted therapies for metastatic non-small cell lung cancer (NSCLC)

Background: Non-small cell lung cancer (NSCLC) imposes a substantial burden on patients, health care systems and society due to increasing incidence and poor survival rates. In recent years, advances in the treatment of metastatic NSCLC have resulted from the introduction of targeted therapies. However, the application of these new agents increases treatment costs considerably. The objective of this article is to review the economic evidence of targeted therapies in metastatic NSCLC. Methods: A systematic literature review was conducted to identify cost-effectiveness (CE) as well as cost-utility studies. Medline, Embase, SciSearch, Cochrane, and 9 other databases were searched from 2000 through April 2013 (including update) for full-text publications. The quality of the studies was assessed via the validated Quality of Health Economic Studies (QHES) instrument. Results: Nineteen studies (including update) involving the MoAb bevacizumab and the Tyrosine-kinase inhibitors erlotinib and gefitinib met all inclusion criteria. The majority of studies analyzed the CE of first-line maintenance and second-line treatment with erlotinib. Five studies dealt with bevacizumab in first-line regimes. Gefitinib and pharmacogenomic profiling were each covered by only two studies. Furthermore, the available evidence was of only fair quality. Conclusion: First-line maintenance treatment with erlotinib compared to Best Supportive Care (BSC) can be considered cost-effective. In comparison to docetaxel, erlotinib is likely to be cost-effective in subsequent treatment regimens as well. The insights for bevacizumab are miscellaneous. There are findings that gefitinib is cost-effective in first- and second-line treatment, however, based on only two studies. The role of pharmacogenomic testing needs to be evaluated. Therefore, future research should improve the available evidence and consider pharmacogenomic profiling as specified by the European Medicines Agency. Upcoming agents like crizotinib and afatinib need to be analyzed as well. © Lange et al.

The concept of low glycemic index and glycemic load foods as panacea for type 2 diabetes mellitus; prospects, challenges and solutions.

Background: This article examines the concepts of low glycemic indices (GIs) and glycemic load (GL) foods as key drivers in the dietary management of type 2 diabetes as well as their shortcomings. The controversies arising from the analysis of glycemic index (GI) and GL of foods such as their reproducibility as well as their relevance to the dietary management of type 2 diabetes are also discussed. Methods: Search was conducted in relevant electronic databases such as: Pubmed, Google Scholar, HINARI, the Cochrane library, Popline, LILACS, CINAHL, EMBASE, etc to identify the current status of knowledge regarding the controversies surrounding management of diabetes with low GI and GL foods. Conclusion: This article suggests that in view of discrepancies that surround the results of GI versus GL of foods, any assay on the GI and GL of a food with the aim of recommending the food for the dietary management of type 2 diabetes, could be balanced with glycated hemoglobin assays before they are adopted as useful antidiabetic foods.

Interventions for dysphagia in acute stroke (Review)

Background It is unclear how dysphagic patients should be fed and treated after acute stroke. Objectives The objective of this review was to assess the effect of different management strategies for dysphagic stroke patients, in particular how and when to feed, whether to supplement nutritional intake, and how and whether to treat dysphagia. Search strategy We searched the Cochrane Stroke Group trials register, Medline, Embase, ISI, and existing review articles.We contacted researchers in the field and equipment manufacturers. Date of the most recent searches: March 1999. Selection criteria Unconfounded truly or quasi randomised controlled trials in dysphagic patients with acute/subacute (within 3 months) stroke. Data collection and analysis Three reviewers independently applied the trial inclusion criteria. Two reviewers assessed trial quality and extracted the data. Main results Percutaneous endoscopic gastrostomy (PEG) versus nasogastric tube (NGT) feeding: two trials (49 patients) suggest that PEG reduces end-of-trial case fatality (Peto Odds Ratio, OR 0.28, 95% CI 0.09 to 0.89) and treatment failures (OR 0.10, 95% CI 0.02 to 0.52), and improves nutritional status, assessed as weight (Weighted Men Difference, WMD +4.1 kg, 95% CI -4.3 to +12.5), mid-arm circumference (WMD +2.2 cm, 95% CI -0.5 to +4.9) or serum albumin (WMD + 7.0 g/l, 95% CI +4.9 to +9.1) as compared with NGT feeding; two larger studies are ongoing. Timing of feeding: no completed trials; one large study is ongoing. Swallowing therapy for dysphagia: two trials (85 patients) suggest that formal swallowing therapy does not significantly reduce end-of-trial dysphagia rates (OR 0.55, 95%CI 0.18 to 1.66). Drug therapy for dysphagia: one trial (17 patients); nifedipine did not alter end-of-trial case fatality or the frequency of dysphagia. Nutritional supplementation: one trial (42 patients) found a non-significant trend to a lower case fatality, and significantly increased energy and protein intake; one large trial is ongoing and data is awaited from two other studies. Fluid supplementation: one trial (20 patients) found that supplementation did not alter the time to resolution of dysphagia. Authors’ conclusions Too few studies have been performed, and these have involved too few patients. PEG feeding may improve outcome and nutrition as compared with NGT feeding. Further research is required to assess how and when patients are fed, and the effect of swallowing or drug therapy on dysphagia.

Relationship between IL-10 gene -819C/T polymorphism and the risk of inflammatory bowel disease: a meta-analysis.

Background: The -819C/T polymorphism in interleukin 10 (IL-10) gene has been reported to be associated with inflammatory bowel disease (IBD) ,but the previous results are conflicting. Materials and Methods: The present study aimed at investigating the association between this polymorphism and risk of IBD using a meta-analysis.PubMed,Web of Science,EMBASE,google scholar and China National Knowledge Infrastructure (CNKI) databases were systematically searched to identify relevant publications from their inception to April 2016.Pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using fixed- or random-effects models. Results: A total of 7 case-control studies containing 1890 patients and 2929 controls were enrolled into this meta-analysis, and our results showed no association between IL-10 gene -819C/T polymorphism and IBD risk(TT vs. CC:OR=0.81,95%CI 0.64- 1.04;CT vs. CC:OR=0.92,95%CI 0.81-1.05; Dominant model: OR=0.90,95%CI 0.80-1.02; Recessive model: OR=0.84,95%CI 0.66-1.06). In a subgroup analysis by nationality, the -819C/T polymorphism was not associated with IBD in both Asians and Caucasians. In the subgroup analysis stratified by IBD type, significant association was found in Crohn’s disease(CD)(CT vs. CC:OR=0.68,95%CI 0.48-0.97). Conclusion: In summary, the present meta-analysis suggests that the IL-10 gene -819C/T polymorphism may be associated with CD risk.

Contribución de los Acidos Grasos Omega-3 para la Memoria y la Función Cognitiva

Una disminución de la función cognitiva y de la memoria se considera que es una consecuencia normal del envejecimiento. Los ácidos grasos omega-3 poliinsaturados son cada vez más propuestos como suplementos dietéticos con la capacidad de reducir el riesgo de deterioro cognitivo, incluyendo la enfermedad de Alzheimer (EA). Objetivo: Estudiar el efecto de los omega-3 en el deterioro cognitivo a través de la revisión de estudios recientes de observación, intervención y experimentales. Métodos: Se realizó una búsqueda en PubMed, Medline, Cochrane y Embase para los estudios epidemiológicos y clínicos en la literatura internacional que utilizan combinaciones de las siguientes palabras clave: "la enfermedad de Alzheimer", "deterioro cognitivo leve", "función cognitiva", "factores dietéticos", "ácidos grasos omega-3", "EPA y DHA". Conclusiones: Los estudios han demostrado el papel protector de los ácidos grasos omega-3 en el deterioro cognitivo leve, demencia y en el riesgo y la progresión de la enfermedad de Alzheimer en los adultos mayores. Se necesitan más estudios para comprender el mecanismo de acción de los ácidos grasos omega-3 sobre la cognición. Las dosis, la composición de cápsulas de EPA y DHA y el tiempo de suplementación deben ser explorados.

The Effectiveness of Community-Based Nutrition Education on the Nutrition Status of Under-five Children in Developing Countries. A Systematic Review

Aim This systematic review aimed at examining the best available evidence on the effectiveness of community-based nutrition education in improving the nutrition status of under five children in developing countries. Methods A systematic search of the literature was conducted utilising the following data bases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, Medline, and Web of Knowledge. 9 studies were identified for the critical appraisal process. The Joanna Briggs Institute (JBI) critical appraisal check-list for experimental studies was utilised and two reviewers conducted the appraisal process independently. 7 studies were included for this review and data was extracted using the JBI data extraction form for experimental studies. The extracted data was heterogeneous as such narrative synthesis was conducted. Results The nutritional status of children in all studies improved and this was evidenced by increases in weight, height, mid upper arm circumference and reduced morbidity. Key messages about education were age at introduction of complementary foods, nutrition value on different types of feeds found locally and frequency of feeding the children. However, there were varied Results regarding the effects of the intervention on the nutrition status of children. This was attributed by differences in implementers’ characteristics, different intervention strategy and intensity, difference in age of the children at enrolment, pre-existing children’s growth and nutritional status and follow-up periods. In addition to home visiting, conducting group meetings of care givers and community leaders, providing education twice a week and use of cooking demonstrations have shown that they produce highly significant findings. Conclusion The evidence from the identified studies suggests that community- based nutrition education improves the nutrition status of under-five children in developing countries.

Granulocyte-colony stimulating factor in experimental stroke and its effects on infarct size and functional outcome: a systematic review

Background Granulocyte-colony stimulating factor (G-CSF) shows promise as a treatment for stroke. This systematic review assesses G-CSF in experimental ischaemic stroke. Methods Relevant studies were identified with searches of Medline, Embase and PubMed. Data were extracted on stroke lesion size, neurological outcome and quality, and analysed using Cochrane Review Manager using random effects models; results are expressed as standardised mean difference (SMD) and odds ratio (OR). Results Data were included from 19 publications incorporating 666 animals. G-CSF reduced lesion size significantly in transient (SMD -1.63, p<0.00001) but not permanent (SMD -1.56, p=0.11) focal models of ischaemia. Lesion size was reduced at all doses and with treatment commenced within 4 hours of transient ischaemia. Neurological deficit (SMD -1.37, p=0.0004) and limb placement (SMD -1.88, p=0.003) improved with G-CSF; however, locomotor activity (>4 weeks post ischaemia) was not (SMD 0.76, p=0.35). Death (OR 0.27, p<0.0001) was reduced with G-CSF. Median study quality was 4 (range 0-7/8); Egger’s test suggested significant publication bias (p=0.001). Conclusions G-CSF significantly reduced lesion size in transient but not permanent models of ischaemic stroke. Motor impairment and death were also reduced. Further studies assessing dose-response, administration time, length of ischaemia and long-term functional recovery are needed.

Técnicas de epiduroscopia en el tratamiento del dolor lumbar: una revisión sistemática de la literatura

Objetivo: El dolor lumbar es una de las patologías más complejas en términos de costo-efectividad de los tratamientos. En este estudio evaluamos la utilidad de la epiduroscopia en el manejo de dolor lumbar, y su beneficio en comparación con las técnicas percutáneas tradicionales. Materiales y métodos: Se realizó una búsqueda de manera sistemática en las bases de datos PubMed, EMBASE, Cochrane y MedLine para artículos publicados entre enero de 1990 y diciembre de 2013. Se incluyeron estudios clínicos descriptivos y experimentos clínicos aleatorizados, excluyéndose estudios no clínicos, opiniones de expertos, etc. Resultados: Se obtuvieron 353 artículos en las 4 bases de datos, de los cuales sólo 78 pasaron el corte según criterios de exclusión e inclusión. Posteriormente se realizó un análisis crítico de los artículos según parámetros estandarizados. De los 78 artículos evaluados, se incluyeron 24 en la revisión final, 14 estudios evaluaron lisis de adherencias e inyección de esteroides, 3 estudios evaluaron la efectividad de la inyección epidural dirigida por epiduroscopia, mientras que los 7 restantes evaluaron otras intervenciones. Conclusiones: La epiduroscopia es una tecnología útil en el tratamiento del dolor lumbar con diferencias significativas en los resultados a largo plazo en ciertos pacientes. Esta tecnología es más útil en pacientes con antecedente quirúrgico con síntomas persistentes que en pacientes que no han sido intervenidos. De igual manera, cuando el dolor es de características radiculares, los resultados a largo plazo son más favorables que cuando se trata de dolor axial o inespecífico.

Los pediatras en la prevención de enfermedades bucales

Introducción: las patologías orales en los niños, como la caries, gingivitis y las maloclusiones constituyen un problema de salud pública mundial, y parecen corresponder sólo a los odontólogos pediatras, pero cabe resaltar que la prevención es uno de los temas en que los médicos pediatras deben contribuir. Objetivo: determinar la importancia sobre la participación del pediatra en la prevención de enfermedades orales y plantear un programa de atención en la intercepción y detección en el transcurso de su revisión habitual. Materiales y métodos: revisión de la literatura a través de artículos indexados en Cochrane, Medline, Lilacs, EMBASE, Amedeo y SciELO, enfatizando los últimos cinco años, en los idiomas: francés, italiano, portugués, inglés y español. Conclusiones: la mayoría de los pediatras no elaboran revisiones preventivas en relación a las patologías orales. El pediatra con los conocimientos básicos y las estrategias de derivación oportunas, puede intervenir en la detección y en la prevención de las patologías orales e intercepción de futuras maloclusiones, a la par del odontopediatra, evitando que las enfermedades bucales generen daño. De esta manera se contribuye al mejoramiento de la salud general de la población infantil.

El diseño de preguntas clínicas en la práctica basada en la evidencia: modelos de formulación

Objetivo: Identificar estructuras estandarizadas para la formulación de preguntas clínicas en el marco de la práctica basada en la evidencia. Método: Se realizó una revisión de la literatura. La búsqueda bibliográfica se efectuó en las bases de datos MEDLINE, CINAHL, EMBASE y LILACS, y en el buscador académico Google Scholar. Se efectuaron estrategias de búsqueda sensibles y acordes a cada base de datos. Límites de búsqueda: intervalo de tiempo (enero de 1995 a abril de 2015), idioma (artículos en inglés). Se usaron palabras clave libres y descriptores del Medical Subject Headings (MeSH) pertinentes: evidence based practice, question, formulation, well-built question, framework. Resultados: Se encontraron 10 manuscritos que aportaron el diseño original de estructuras para la formulación de preguntas clínicas en el ámbito de la práctica basada en la evidencia. El modelo PICO es la estructura más conocida y comúnmente utilizada en investigación cuantitativa y de él derivan los modelos PICOT, PICOTT, PICOS, PIPOH, PECORD, PESICO. En el campo de la gestión sanitaria la estructura ECLIPSE se erige para formulación de preguntas relacionadas con la gestión. Por último, para la búsqueda de evidencias cualitativas se han configurado los modelos SPICE y SPIDER adecuando sus componentes al fenómeno cualitativo. Conclusiones: Estos modelos estandarizadas se comportan como un instrumento idóneo para guiar la estrategia de búsqueda y delimitar el área de interés. Dada la gran variedad de piezas que integran las estructuras, su conocimiento exhaustivo acrecienta sus usos potenciales. Estas estructuras no deben ser consideradas como una guía rígida a la que ceñirse ineludiblemente.

Commercial enzyme-linked immunosorbent assay versus polymerase chain reaction for the diagnosis of chronic Chagas disease: a systematic review and meta-analysis

Chronic Chagas disease diagnosis relies on laboratory tests due to its clinical characteristics. The aim of this research was to review commercial enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) diagnostic test performance. Performance of commercial ELISA or PCR for the diagnosis of chronic Chagas disease were systematically searched in PubMed, Scopus, Embase, ISI Web, and LILACS through the bibliography from 1980-2014 and by contact with the manufacturers. The risk of bias was assessed with QUADAS-2. Heterogeneity was estimated with the I2 statistic. Accuracies provided by the manufacturers usually overestimate the accuracy provided by academia. The risk of bias is high in most tests and in most QUADAS dimensions. Heterogeneity is high in either sensitivity, specificity, or both. The evidence regarding commercial ELISA and ELISA-rec sensitivity and specificity indicates that there is overestimation. The current recommendation to use two simultaneous serological tests can be supported by the risk of bias analysis and the amount of heterogeneity but not by the observed accuracies. The usefulness of PCR tests are debatable and health care providers should not order them on a routine basis. PCR may be used in selected cases due to its potential to detect seronegative subjects.

Alcohol consumption and lung cancer risk in never smokers

Objective: The main objective of this study is to analyse the role of alcohol consumption on lung cancer risk in people who have never smoked. Methods: We conducted a systematic review of the scientific literature following the PRISMA statement. We searched Medline, EMBASE and CINAHL using different combinations of MeSH terms and free text. We included cohort studies, pooled cohort studies and case-control studies comprising at least 25 anatomopathologically-confirmed diagnoses of lung cancer cases, a sample size larger than 100 individuals and more than five years of follow-up for cohort studies. We excluded studies that did not specifically report results for never smokers. We developed a quality score to assess the quality of the included papers and we ultimately included 14 investigations with a heterogeneous design and methodology. Results: Results for alcohol consumption and lung cancer risk in never smokers are inconclusive; however, several studies showed a dose-response pattern for total alcohol consumption and for spirits. Heterogeneous results were found for wine and beer. Conclusion: No clear effect is observed for alcohol consumption. Due to the limited evidence, no conclusion can be drawn for beer or wine consumption. There is little research available on the effect of alcohol on lung cancer risk for people who have never smoked, and more studies are urgently needed on this topic.

Does therapeutic writing help people with long-term conditions? Systematic review, realist synthesis and economic considerations

Background Writing therapy to improve physical or mental health can take many forms. The most researched model of therapeutic writing (TW) is unfacilitated, individual expressive writing (written emotional disclosure). Facilitated writing activities are less widely researched. Data sources Databases including: MEDLINE, EMBASE, PsychINFO, Linguistics and Language Behavior Abstracts, AMED, and CINHAL were searched from inception to March 2013. Review methods Four TW practitioners provided expert advice. Study procedures were conducted by one reviewer and checked by a second. Randomised controlled trials (RCTs) and non-randomised comparative studies were included. Quality was appraised using the Cochrane risk of bias tool. Unfacilitated and facilitated TW studies were analysed separately under ICD-10 chapter headings. Meta-analyses were performed where possible using Revman 5.2. Costs were estimated from an NHS perspective and three cost-consequence case studies were prepared. Realist synthesis followed RAMESES guidelines. Objectives To review the clinical and cost-effectiveness of TW for people with long-term health conditions (LTCs) compared to no writing, or other controls, reporting any relevant clinical outcomes. To conduct a realist synthesis to understand how TW might work, and for whom. Results From 14,658 unique citations, 284 full text papers were reviewed and 64 studies (58 RCTs) were included in the final effectiveness reviews. Five studies examined facilitated TW, these were extremely heterogeneous with unclear or high risk of bias, but suggested that facilitated TW interventions may be beneficial in individual LTCs. Unfacilitated expressive writing was examined in 59 studies of variable, or unreported, quality. Overall there was very little or no evidence of any benefit reported in the following conditions (number of studies): HIV (six); breast cancer (eight); gynaecological and genitourinary cancers (five); mental health (five); asthma (four); psoriasis (three); chronic pain (four). In inflammatory arthropathies (six) there was a reduction in disease severity (n= 191, standardised mean difference (SMD) - 0.61 [95% confidence intervals (95% CI) -0.96, -0.26]) in the short term on meta-analysis of four studies. For all other LTCs there was either no, or sparse, data with no, or inconsistent, evidence of benefit. Meta-analyses conducted across all the LTCs provided no evidence that unfacilitated EW had any effect on depression at short term (n= 1,563, SMD -0.06, 95% CI -0.29 to 0.17, substantial heterogeneity), or long term (n= 778, SMD-0.04 95% CI -0.18 to 0.10, little heterogeneity) follow up, or on anxiety, physiological or biomarker-based outcomes. One study reported costs, none reported cost-effectiveness, twelve reported resource use; meta-analysis suggested reduced medication use but no impact on health centre visits. Estimated costs of intervention were low, but there was insufficient evidence to judge cost-effectiveness. Realist review findings suggested that facilitated TW is a complex intervention and group interaction contributes to the perception of benefit. It was unclear from the available data who might benefit most from facilitated TW. Limitations Difficulties with developing realist review programme theory meant that mechanisms operating during TW remain obscure. Conclusions Overall there is little evidence to support the effectiveness or cost-effectiveness of unfacilitated expressive writing interventions in people with LTCs. Further research focussed on facilitated TW in people with LTCs could be informative.

Intervenções de enfermagem eficazes no apoio ao familiar cuidador de pessoa com demência não institucionalizada: Revisão sistemática

O aumento do número de pessoas com demência e dos custos associados aos cuidados de saúde, levam à crescente necessidade de providenciar apoio efetivo aos familiares cuidadores (FCs), no sentido de potenciar as capacidades destes e diminuir os riscos de morbilidade. Objetivo: A presente revisão sistemática da literatura (RSL) tem como objetivo identificar as intervenções de enfermagem eficazes no apoio ao FC de pessoa com demência, não institucionalizada. Método: Foi realizada uma pesquisa eletrónica de artigos, nas bases de dados CINAHL, MEDLINE, EMBASE, PsycINFO, The Cochrane Database of Systematic Reviews, The JBI Database of Systematic Reviews and Implementation Reports, e Repositório Científico de Acesso Aberto de Portugal, no intervalo de tempo de 2006 – 2014. Foram considerados estudos experimentais e quase-experimentais, RSL e meta-analises, publicados em português, inglês e espanhol. Resultados: No total 11 estudos foram incluídos na revisão, cinco estudos primários e seis estudos secundários. De entre os estudos primários, todas as intervenções implementadas foram de caráter psicoeducacional e mostraram-se, de um modo geral, mais eficazes na melhoria da perceção do FC quanto à sua competência no desempenho do papel. Os resultados mostraram-se inconclusivos acerca do benefício destas intervenções na diminuição da depressão, da sobrecarga e do stress do FC. Quanto aos estudos secundários, foram vários os tipos de intervenções estudados: intervenções implementadas através da internet; intervenções psicoeducacionais; intervenções de suporte/ aconselhamento; e multicomponentes. A maioria dos estudos avaliaram os resultados depressão/ sintomas depressivos, perceção de competência ou autoeficácia, sobrecarga e qualidade de vida. De uma forma geral, os resultados em que as intervenções de apoio aos cuidadores se mostraram mais eficazes foram a autoeficácia, a sobrecarga e a depressão/ sintomas depressivos. Conclusão: As intervenções psicoeducacionais, pelo impacto que têm e pelo potencial de desenvolvimento de competências no FC, apresentam-se como uma mais valia a longo prazo. A sobrecarga poderá surgir, mas será lícito questionarmos se o processo não será retardado. Importa assim, desenvolver estudos que possam mostrar estas relações.
