Paediatricians' expectations and perspectives regarding genetic testing for children with developmental disorders.

AIM: To investigate paediatricians' expectations and perspectives of genetic testing for children with developmental disorders. METHODS: Paediatricians working in a developmental clinic were surveyed each time they ordered a chromosomal microarray (CMA) for a child with developmental disorders. Clinical charts were reviewed. Results were analysed using mixed methodology. RESULTS: Ninety-seven % (73/76) of surveys were completed. Paediatricians reported that 36% of parents had difficulties understanding genetic testing and that 40% seemed anxious. The majority expected testing to have positive impacts on children/families. The themes raised were (i) clarifying the diagnosis (56%), (ii) understanding the aetiology of the condition (55%), (iii) enabling prenatal diagnosis/counselling (43%), (iv) improving medical care for the child (15%) and (v) decreasing parental guilt/anxiety (8%). Less than half anticipated negative impacts; 74% expected that the most helpful result for their patient would be an abnormal result explaining the disorder. Among the 73 children for whom CMA was ordered, 81% got tested: 66% of the results were normal, 19% were abnormal and contributed to explain the condition and 12% were abnormal but of unknown significance. CONCLUSION: Paediatricians generally expect many positive and less negative impacts of genetic testing for children with developmental disorders. Parental perspectives are needed.

Paediatricians underuse recommended genetic tests in children with global developmental delay.

OBJECTIVES: To assess paediatricians' use of genetic testing for children with global developmental delay (GDD). STUDY DESIGN: We developed and piloted a questionnaire assessing the use of genetic tests in children with GDD and awareness of relevant guidelines. All practicing Quebec paediatricians were contacted. Paediatricians who did not evaluate children with GDD in their practice were excluded. Descriptive and statistical analyses were performed with SPSS. RESULTS: Of the 651 paediatricians, 225 answered (34.5%) and 141 were eligible. Only 31.9% were familiar with at least one guideline about genetic tests for the investigation of children with GDD, but 93.6% had ordered genetic testing for children with GDD (Fragile X testing [92.9%], karyotype [87.2%] and chromosomal microarray [63.8%]). Based on vignettes, 20.6% of participants would order genetic tests for isolated GDD and 95.0% for GDD with dysmorphic features and microcephaly. Only 56.7% ordered Fragile X testing for a girl with GDD and a known family history of Fragile X syndrome. Use of tests for isolated GDD was increased in presence of maternal pregnancy, compared with absence of pregnancy (44.7% and 27.7%, respectively). More participants would order genetic tests for a child with GDD and fetal exposure to alcohol (69.5%) than isolated GDD (20.6%). CONCLUSIONS: Even though paediatricians often order genetic testing for children with GDD, practices and knowledge regarding testing are not optimal. As new and more complex genetic tests are developed, up-to-date training about the use of genetic tests for children with GDD needs to be integrated into paediatrics residency programs and continuous medical education.

Partnering with parents to disclose Klinefelter syndrome to their child.

UNLABELLED: In paediatrics, a diagnosis of Klinefelter syndrome can occur after prenatal testing or because of symptoms such as learning difficulties or incomplete puberty. After the diagnosis, parents have to decide when and how to speak about this condition to their child. Parents and healthcare professionals (HCPs) may have different perceptions related to disclosure of this diagnosis. Due to the absence of clear guidelines, parents and HCPs may feel uncomfortable discussing the condition and may hide the truth in a prolonged fashion. CONCLUSION: For patients with a prenatal diagnosis, we recommend a gradual and personalised disclosure process starting between the ages of 5 and 13 years. For older patients, a personalised approach should also be the goal. Various communication strategies and recommendations regarding disclosure of Klinefelter syndrome are proposed.

Caudal-related homeobox (Cdx) protein-dependent integration of canonical Wnt signaling on paired-box 3 (Pax3) neural crest enhancer.

One of the earliest events in neural crest development takes place at the neural plate border and consists in the induction of Pax3 expression by posteriorizing Wnt·ß-catenin signaling. The molecular mechanism of this regulation is not well understood, but several observations suggest a role for posteriorizing Cdx transcription factors (Cdx1/2/4) in this process. Cdx genes are known as integrators of posteriorizing signals from Wnt, retinoic acid, and FGF pathways. In this work, we report that Wnt-mediated regulation of murine Pax3 expression is indirect and involves Cdx proteins as intermediates. We show that Pax3 transcripts co-localize with Cdx proteins in the posterior neurectoderm and that neural Pax3 expression is reduced in Cdx1-null embryos. Using Wnt3a-treated P19 cells and neural crest-derived Neuro2a cells, we demonstrate that Pax3 expression is induced by the Wnt-Cdx pathway. Co-transfection analyses, electrophoretic mobility shift assays, chromatin immunoprecipitation, and transgenic studies further indicate that Cdx proteins operate via direct binding to an evolutionarily conserved neural crest enhancer of the Pax3 proximal promoter. Taken together, these results suggest a novel neural function for Cdx proteins within the gene regulatory network controlling neural crest development.

Inhibition of glycogen synthase kinase-3 activity triggers an apoptotic response in pancreatic cancer cells through JNK-dependent mechanisms.

Recent evidences suggest that the activity of glycogen synthase kinase-3 (GSK3) contributes to the tumorigenic potential of pancreatic cancer cells through modulation of cell proliferation and survival. However, further investigations are needed to identify GSK3-dependent mechanisms involved in the control of pancreatic cancer cell proliferation and survival. This study was undertaken to provide further support for a role of GSK3 in pancreatic cancer cell growth as well as to identify new cellular and molecular mechanisms involved. Herein, we demonstrate that prolonged inhibition of GSK3 triggers an apoptotic response only in human pancreatic cancer cells but not in human non-transformed pancreatic epithelial cells. We show that prolonged inhibition of GSK3 activity increases Bim messenger RNA and protein expressions. Moreover, we provide evidence that activation of the c-jun N-terminal kinase (JNK) pathway is necessary for the GSK3 inhibition-mediated increase in Bim expression and apoptotic response. Finally, we demonstrate that concomitant inhibition of GSK3 potentiates the death ligand-induced apoptotic response in pancreatic cancer cells but not in non-transformed pancreatic epithelial cells and that this effect also requires JNK activity. Considering that different approaches leading to stimulation of death receptor signaling are under clinical trials for treatment of unresectable or metastatic pancreatic cancer, inhibition of GSK3 could represent an attractive new avenue to improve their effectiveness.

Fano resonances in the midinfrared spectra of single-walled carbon nanotubes.

This work revisits the physics giving rise to the carbon nanotube phonon bands in the midinfrared. Our measurements of doped and undoped samples of single-walled carbon nanotubes in Fourier transform infrared spectroscopy show that the phonon bands exhibit an asymmetric line shape and that their effective cross section is enhanced upon doping. We relate these observations to electron-phonon coupling or, more specifically, to a Fano resonance phenomenon. We note that the dopant-induced intraband (not interband) continuum couples strongly to the phonon modes, and that defects created on the sidewall are scattering centers that increase the spectral amplitude of the resonance.

Swimming away or clamming up: the use of phasic and tonic adductor muscles during escape responses varies with shell morphology in scallops.

The simple locomotor system of scallops facilitates the study of muscle use during locomotion. We compared five species of scallops with different shell morphologies to see whether shell morphology and muscle use change in parallel or whether muscle use can compensate for morphological constraints. Force recordings during escape responses revealed that the use of tonic and phasic contractions varied markedly among species. The active species, Amusium balloti, Placopecten magellanicus and Pecten fumatus, made more phasic contractions than the more sedentary species, Mimachlamys asperrima and Crassadoma gigantea. Tonic contractions varied considerably among these species, with the two more sedentary species often starting their response to the predator with a tonic contraction and the more active species using shorter tonic contractions between series of phasic contractions. Placopecten magellanicus made extensive use of short tonic contractions. Pecten fumatus mounted an intense series of phasic contractions at the start of its response, perhaps to overcome the constraints of its unfavourable shell morphology. Valve closure by the more sedentary species suggests that their shell morphology protects them against predation, whereas swimming by the more active species relies upon intense phasic contractions together with favourable shell characteristics.

Training family physicians and residents in family medicine in shared decision making to improve clinical decisions regarding the use of antibiotics for acute respiratory infections: protocol for a clustered randomized controlled trial.

BACKGROUND: To explore ways to reduce the overuse of antibiotics for acute respiratory infections (ARIs), we conducted a pilot clustered randomized controlled trial (RCT) to evaluate DECISION+, a training program in shared decision making (SDM) for family physicians (FPs). This pilot project demonstrated the feasibility of conducting a large clustered RCT and showed that DECISION+ reduced the proportion of patients who decided to use antibiotics immediately after consulting their physician. Consequently, the objective of this study is to evaluate, in patients consulting for ARIs, if exposure of physicians to a modified version of DECISION+, DECISION+2, would reduce the proportion of patients who decide to use antibiotics immediately after consulting their physician. METHODS/DESIGN: The study is a multi-center, two-arm, parallel clustered RCT. The 12 family practice teaching units (FPTUs) in the network of the Department of Family Medicine and Emergency Medicine of Université Laval will be randomized to a DECISION+2 intervention group (experimental group) or to a no-intervention control group. These FPTUs will recruit patients consulting family physicians and residents in family medicine enrolled in the study. There will be two data collection periods: pre-intervention (baseline) including 175 patients with ARIs in each study arm, and post-intervention including 175 patients with ARIs in each study arm (total n = 700). The primary outcome will be the proportion of patients reporting a decision to use antibiotics immediately after consulting their physician. Secondary outcome measures include: 1) physicians and patients' decisional conflict; 2) the agreement between the parties' decisional conflict scores; and 3) perception of patients and physicians that SDM occurred. Also in patients, at 2 weeks follow-up, adherence to the decision, consultation for the same reason, decisional regret, and quality of life will be assessed. Finally, in both patients and physicians, intention to engage in SDM in future clinical encounters will be assessed. Intention-to-treat analyses will be applied and account for the nested design of the trial will be taken into consideration. DISCUSSION: DECISION+2 has the potential to reduce antibiotics use for ARIs by priming physicians and patients to share decisional process and empowering patients to make informed, value-based decisions.

A large ribonucleoprotein particle induced by cytoplasmic PrP shares striking similarities with the chromatoid body, an RNA granule predicted to function in posttranscriptional gene regulation.

The observation that PrP is present in the cytosol of some neurons and non-neuronal cells and that the N-terminal signal peptide is slightly inefficient has brought speculations concerning a possible function of the protein in the cytosol. Here, we show that cells expressing a cytosolic form of PrP termed cyPrP display a large juxtanuclear cytoplasmic RNA organelle. Although cyPrP spontaneously forms aggresomes, we used several mutants to demonstrate that the assembly of this RNA organelle is independent from cyPrP aggregation. Components of the organelle fall into three classes: mRNAs; proteins, including the RNAseIII family polymerase Dicer, the decapping enzyme Dcp1a, the DEAD-box RNA helicase DDX6, and the small nuclear ribonucleoprotein-associated proteins SmB/B'/N; and non-coding RNAs, including rRNA 5S, tRNAs, U1 small nuclear RNA, and microRNAs. This composition is similar to RNA granules or chromatoid bodies from germ cells, or planarian stem cells and neurons, which are large ribonucleoprotein complexes predicted to function in RNA processing and posttranscriptional gene regulation. The domain of PrP encompassing residues 30 to 49 is essential for the formation of the RNA particle. Our findings confirm the intriguing relation between PrP and RNA in cells, and underscore an unexpected function for cytosolic PrP: assembling a large RNA processing center which we have termed PrP-RNP for PrP-induced ribonucleoprotein particle.

Differentiation of the pattern of cognitive impairment between depressed and non-depressed patients with dementia living in long-term care facilities.

OBJECTIVE: The principal objective of this study is to examine the cognitive profile of patients with dementia plus (D+ group) and without (D- group) concomitant depression. METHOD: The D+ (N = 61) and D- (N = 89) patients were recruited in long-term care facilities. The depression status of the participants was determined using the Cornell Scale for Depression in Dementia. Cognitive functioning was assessed using the Hierarchic Dementia Scale (HDS). RESULTS: The analyses first indicated that on the total HDS score, patients of the D+ group exhibited more severe cognitive impairment compared to those of the D- group. Further analyses revealed that the difference between groups pertained to perception, attention/memory, calculation, and language functions. Moreover, secondary analyses revealed that the cognitive deficits of the D+ group were associated with behavioral (agitation and retardation, in particular), but not with mood-related, symptoms of depression. Interestingly, ideational symptoms of depression (suicide and self-depreciation, in particular) were positively correlated with cognitive impairment. CONCLUSION: These findings add to those of previous studies showing that D+ and D- patients differ not only regarding the presence or absence of depressive symptoms, but also regarding cognitive manifestations. This study thus reinforces the need to detect and treat accurately depression in dementia.

Efficacy of a cognitive training programme for mild cognitive impairment: results of a randomised controlled study.

This study aimed to determine the efficacy of cognitive training in a 10-week randomised controlled study involving 22 individuals presenting with mild cognitive impairment of the amnestic type (MCI-A). Participants in the experimental group (n = 11) learned face-name associations using a paradigm combining errorless (EL) learning and spaced retrieval (SR) whereas participants in the control group (n = 11) were trained using an errorful (EF) learning paradigm. Psycho-educational sessions on memory were also provided to all participants. After neuropsychological screening and baseline evaluations, the cognitive training took place in 6 sessions over a 3-week period. The post-training and follow-up evaluations, at one and four weeks respectively, were performed by research assistants blind to the participant's study group. The results showed that regardless of the training condition, all participants improved their capacity to learn face-name associations. A significant amelioration was also observed in participant satisfaction regarding their memory functioning and in the frequency with which the participants used strategies to support memory functions in daily life. The absence of difference between groups on all variables might be partly explained by the high variability of scores within the experimental group. Other studies are needed in order to verify the efficacy of EL learning and SR over EF in MCI-A.

Impact of a meaning-centered intervention on job satisfaction and on quality of life among palliative care nurses.

OBJECTIVE: Palliative care (PC) nurses experience several recurrent organizational, professional, and individual challenges. To address existential and emotional demands, the meaning-centered intervention was recently developed. The intervention applied didactic and process-oriented strategies, including guided reflections, experiential exercises, and education based on themes of Viktor Frankl's logotherapy. The objective of this study was to test its efficiency to improve job satisfaction and quality of life in PC nurses from three regional districts in Quebec Province, Canada. METHODS: A randomized waiting-list group design was conducted, intervention group (n=56) versus waiting-list group (n=53). Job satisfaction, perception of benefits of working in PC, and spiritual and emotional quality of life were measured at pre-, posttest, and 3-month follow-up. RESULTS: The PC nurses in the experimental group reported more perceived benefits of working in PC after the intervention and at follow-up. Spiritual and emotional quality of life remained, however, unaffected by the intervention. CONCLUSIONS: To explain null findings, theoretical and methodological challenges, related to existential interventions, such as choice of outcomes, and selection bias (participants recruited were healthy workers) are discussed. Future directions and strategies to deal with those issues are proposed.

Diagnostic and Therapeutic Misconception: Parental Expectations and Perspectives Regarding Genetic Testing for Developmental Disorders.

Parents' understanding/expectations regarding genetic testing for children with developmental disorders were explored. Within a month of testing, interviews were conducted with 57 parents. Many (74%) could not recall the nature of testing. Parents expected genetic testing to have positive impacts for the child (93%) and the family (98%), mainly to find the etiology and/or an intervention. Many parents (40%) reported not knowing their child's clinical diagnosis. They expected genetic testing would establish the diagnosis. Parents anticipated potential negative impacts of testing for children (78%) and families (87%), mainly finding another illness or not finding potential interventions. Abnormal results explaining the disorder were found in 9% of children. In summary, genetic results for developmental disorders are unlikely to meet parental expectations.

Pain Catastrophizing Scale for Francophone Adolescents: a preliminary validation.

BACKGROUND: In adults, it is well known that high levels of pain catastrophizing are related to increased pain and disability as well as to heightened anxiety and depression. However, due to the lack of a measure of pain catastrophizing adapted for francophone adolescents, little is known about the role of catastrophizing in this population. OBJECTIVES: To adapt the French version of the Pain Catastrophizing Scale (PCS) and to examine the psychometric properties and factorial structure of the PCS for Francophone Adolescents (PCS-Ado). METHODS: The French version of the PCS was modified by a group of experts. The format of the questions was modified to be appropriate for adolescents aged between 12 and 18 years. To assess the psychometric properties of the PCS-Ado, 345 adolescents completed the PCS-Ado and questionnaires measuring depression, anxiety and intensity of pain. Twelve to 16 weeks later, participants completed the questionnaires again to examine the test-retest reliability of the PCS-Ado. RESULTS: Results revealed a three-factor solution similar to the original PCS. In addition, results revealed that PCS-Ado had good internal consistency (PCS-Ado total: 0.85; rumination: 0.72; magnification: 0.66; helplessness: 0.74), and high test-retest reliability (r=0.73). Finally, significant correlations among catastrophizing, depression, anxiety and pain intensity support the construct validity of the PCS-Ado. CONCLUSIONS: The results suggest that the PCS-Ado is valid and reliable with francophone adolescents. Further research is required to assess the validity of the PCS-Ado in clinical settings.

Swimming performance, metabolic rates, and their correlates in the Iceland scallop Chlamys islandica.

The dramatic escape response of some scallops is modified by reproductive investment and by acclimation temperature. Despite considerable knowledge of the physiology of the escape response, functional links between escape response performance, organismal rates of oxygen uptake, and tissue metabolic capacities are little known. We measured oxygen consumption rates (standard, maximal, and aerobic scope), escape behavior (initial and repeat performance), tissue mass, condition index, protein content, and tissue metabolic capacities in the Iceland scallop Chlamys islandica to examine links between these parameters. Postexercise oxygen consumption rates were positively linked to contraction rate (repeat test) and to pyruvate kinase activity in the adductor muscle but negatively linked to digestive gland wet mass. Swimming behavior was mainly related to activity of glycolytic enzymes, and enzymatic activities were related to anatomic parameters. Scallop behavior and physiology change with size, both within our samples and on a larger scale. Small scallops showed more intense swimming activity and had higher arginine kinase activities but lower glycolytic enzyme activities in their adductor muscle than larger scallops. This corresponds to the ontogenetic change in susceptibility to predation and in habitat use observed in C. islandica.

Development of the Adolescent Cancer Suffering Scale.

BACKGROUND: While mortality due to pediatric cancer has decreased, suffering has increased due to complex and lengthy treatments. Cancer in adolescence has repercussions on personal and physical development. Although suffering can impede recovery, there is no validated scale in French or English to measure suffering in adolescents with cancer. OBJECTIVE: To develop an objective scale to measure suffering in adolescents with cancer. METHODS: A methodological design for instrument development was used. Following a MEDLINE search, semistructured interviews were conducted with adolescents 12 to 19 years of age who had undergone four to six weeks of cancer treatment, and with a multidisciplinary cohort of health care professionals. Adolescents with advanced terminal cancer or cognitive impairment were excluded. Enrollment proceeded from the hematology-oncology department/clinic in Montreal, Quebec, from December 2011 to March 2012. Content validity was assessed by five health care professionals and four adolescents with cancer. RESULTS: Interviews with 19 adolescents and 16 health care professionals identified six realms of suffering: physical, psychological, spiritual, social, cognitive and global. Through iterative feedback, the Adolescent Cancer Suffering Scale (ACSS) was developed, comprising 41 questions on a four-point Likert scale and one open-ended question. Content validity was 0.98, and inter-rater agreement among professionals was 88% for relevance and 86% for clarity. Adolescents considered the scale to be representative of their suffering. CONCLUSIONS: The ACSS is the first questionnaire to measure suffering in adolescents with cancer. In future research, the questionnaire should be validated extensively and interventions developed. Once validated, the ACSS will contribute to promote a holistic approach to health with appropriate intervention or referral.

Scallops show that muscle metabolic capacities reflect locomotor style and morphology.

Although all scallops swim using their adductor muscle to close their valves, scallop species differ considerably in how they use their muscle during escape responses, in parallel with the striking interspecific differences in shell morphology. This provides an excellent opportunity to study links between muscle metabolic capacities and animal performance. We found that the capacity for anaerobic glycolysis and aerobic metabolism, as well as phosphoarginine levels in the phasic adductor muscle, differ with escape response strategy. Phosphoarginine contents were high in species that rely on phasic contractions (Amusium balloti, Placopecten magellanicus, and Pecten fumatus). Arginine kinase activities reflect reliance on rapid initial bursts of phasic contractions. Scallops that maintain their valves in a closed position for prolonged periods (P. fumatus, Mimachlamys asperrima, and Crassadoma gigantea) have high activities of enzymes of anaerobic glycolysis in their phasic adductor muscle. Myosin ATPase activity was lower in the nonswimming scallop, C. gigantea, than in swimming scallops. The different patterns and roles of swimming are reflected in interspecific differences in the biochemical attributes of the phasic adductor muscle. These patterns suggest coevolution of muscle metabolic capacities, patterns of adductor muscle use, and shell morphology in scallops.

The MEK/ERK pathway promotes NOTCH signalling in pancreatic cancer cells.

Activation of the NOTCH receptors relies on their intracellular proteolysis by the gamma-secretase complex. This cleavage liberates the NOTCH intracellular domain (NIC) thereby allowing the translocation of NIC towards the nucleus to assemble into a transcriptional platform. Little information is available regarding the regulatory steps operating on NIC following its release from the transmembrane receptor up to its association with transcriptional partners. Interfering with these regulatory steps might potentially influences the nuclear outcome of NOTCH signalling. Herein, we exploited a reliable model to study the molecular events occurring subsequent to NOTCH1 cleavage. In pancreatic cancer cells, pulse of NOTCH1 activation led to increased expression of NOTCH target genes namely HES1 and c-MYC. We uncovered that, upon its release, the NOTCH1 intracellular domain, NIC1, undergoes a series of post-translational modifications that include phosphorylation. Most interestingly, we found that activation of the MEK/ERK pathway promotes HES1 expression. Inhibition of the gamma-secretase complex prevented the MEK/ERK-induced HES1 expression suggesting a NOTCH-dependent mechanism. Finally, higher levels of NIC1 were found associated with its transcriptional partners [CBF1, Su(H) and LAG-1] (CSL) and MASTERMIND-LIKE 1 (MAML1) upon MEK/ERK activation providing a potential mechanism whereby the MEK/ERK pathway promotes expression of NOTCH target genes. For the first time, our data exposed a signalling pathway, namely the MEK/ERK pathway that positively impacts on NOTCH nuclear outcome.

Attachment and pain outcomes in adolescents: the mediating role of pain catastrophizing and anxiety.

UNLABELLED: This study examined the relations between attachment styles and pain severity/depression in adolescents. Analyses examined whether anxiety and the 3 dimensions of pain catastrophizing mediated the associations between attachment styles, pain severity and depression. A total of 382 high-school students completed questionnaires assessing attachment styles, catastrophizing, depression, anxiety and, for those who reported pain during the last month, pain severity. Results revealed that secure attachment was associated with lower levels of pain severity, depression, pain catastrophizing and anxiety. Preoccupied and fearful attachment styles were associated with heightened pain severity, depression, pain catastrophizing and anxiety. Dismissing attachment style was only associated with high levels of depression and anxiety. Regression analyses revealed that anxiety and the helplessness dimension of pain catastrophizing mediated the relations between secure, preoccupied and fearful attachment styles and pain severity. Moreover, anxiety and the rumination dimension of pain catastrophizing mediated the relation between secure, preoccupied and fearful attachment styles and depression. These findings suggest that anxiety, pain catastrophizing and attachment styles are related processes but nevertheless make independent contributions to the prediction of pain severity and depression. In addition, these findings suggest that attachment styles and cognitive-affective factors might increase the risk of problematic outcomes in adolescents with pain conditions. Theoretical and clinical implications of these results are discussed. PERSPECTIVE: The results of this study revealed that anxiety and the helplessness dimension of pain catastrophizing mediated the relation between attachment and pain severity whereas anxiety and rumination mediated the relation between attachment and depression. Attachment style and cognitive-affective factors might increase vulnerability for problematic pain outcomes in adolescents.

Enhancing meaning in palliative care practice: a meaning-centered intervention to promote job satisfaction.

OBJECTIVES: This article introduces a new meaning-centered psycho-educational group intervention, called Enhancing meaning in palliative care nursing, designed to support nurses providing palliative care. This intervention aims at increasing job satisfaction and quality of life, as well as preventing burnout in this particular population. THEORETICAL FRAMEWORKS: Its format and content are founded on the meaning-centered psychotherapy approach developed for terminally ill cancer patients (Breitbart, 2001; Greenstein & Breitbart, 2000). Frankl's existential therapeutic approach, called logotherapy, serves as the underlying theoretical framework to this intervention. DEVELOPMENT: Following the presentation of the context and the development of the intervention, its content is described. CONCLUSION: A brief description of the ongoing randomized controlled trial testing the intervention is then provided. Finally, the way in which this intervention could contribute to nurses' quality of life and suggestions for future developments are briefly discussed.
