Développement d'une échelle interdisciplinaire bilingue évaluant l'auto-efficacité à participer à l'aide médicale à mourir

Medical Assistance in Dying (MAiD) is a complex process involving the person seeking care and their relatives. MAiD involves physical, psychosocial and spiritual needs, and consequently the involvement of an interdisciplinary team is beneficial. Therefore, updating the knowledge and skills of healthcare and social services professionals is critical. An interdisciplinary team from Laval University (Quebec, Canada) has developed a continuous training program for all health care and social services professionals who could be involved in the care of persons who request MAiD and their loved ones. It is crucial to assess whether the objectives of the continuous training program are being met, especially since this new training addresses several complex issues (legal, ethical, and clinical). Bandura's self-efficacy theory has been widely used to develop scales for assessing the impact of training programs and identifying knowledge gaps. Bandura's theory states that feeling secure in one's self-efficacy leads to self-determined motivation. Although there are various scales intended to measure self-efficacy in palliative care, none include self-efficacy for participating in the process surrounding MAiD. As a result, we aim to create a bilingual (English-French) interdisciplinary scale to assess self-efficacy for participating in the process surrounding MAiD. The scale will allow decision-makers and researchers to identify current knowledge gaps. It will also be useful for assessing the impact of current and future training programs addressing this end-of-life practice. In this work in progress, we briefly introduce the training program and the future steps in the development and validation of the scale.L'aide médicale à mourir (AMM) est un processus complexe impliquant la personne qui demande le soin et ses proches. L'AMM implique des besoins physiques, psychosociaux et spirituels. Par conséquent, l'implication d'une équipe interdisciplinaire est bénéfique et la mise à niveau des connaissances et des compétences des professionnel.es est essentielle. Une équipe interdisciplinaire de l'Université Laval (Québec, Canada) a développé un programme de formation continue destiné aux professionnelles de la santé et des services sociaux susceptible d'être impliqué es dans ls soins et services des personnes qui demandent l’AMM et de leurs proches. Il est crucial d'évaluer si les objectifs du programme de formation continue sont atteints, d'autant plus que cette nouvelle formation aborde plusieurs questions complexes (juridiques, éthiques et cliniques). La théorie du sentiment d'auto efficacité de Bandura a été largement utilisée pour développer des échelles permettant d'évaluer l'impact des programmes de formation et d'identifier les lacunes en matière de connaissances. Cette théorie stipule que le fait de se sentir sûre de son efficacité personnelle conduit à une motivation intrinsèque à accomplir le comportement visé. Bien qu'il existe plusieurs échelles destinées à mesurer l'auto-efficacité dans le domaine des soins palliatifs, aucune n'inclut l'auto-efficacité pour la participation au processus entourant l’AMM. Par conséquent, nous développons une échelle interdisciplinaire bilingue (anglais-français) pour évaluer l'auto-efficacité à participer au processus entourant l’AMM. L'échelle permettra aux décideuses, décideurs et aux chercheuses et chercheurs d'identifier les lacunes actuelles en matière de connaissances. Elle sera également utile pour évaluer l'impact des programmes de formation actuels et futurs portant sur cette pratique de fin de vie. Dans cet article, nous présentons brièvement le programme de formation et les étapes futures du développement et de la validation de l'échelle

Gene profiling of cell cycle progression through S-phase reveals sequential expression of genes required for DNA replication and nucleosome assembly

The ordered expression of genes after growth factor stimulation in G(1) supportsthe onset of DNA replication. To characterize regulatory events during S-phase when cell cycle progression has become growth factor independent, we have profiled the expression of over 7,000 human genes using GeneChip DNA microarray analysis. HeLa cells were synchronized at the beginning of S-phase by thymidine/aphidicolin block, and RNA populations were analyzed throughout the S and G(2) phases. Expression of genes involved in DNA replication is maximal during early S-phase, whereas histone mRNAs peak at mid S-phase. Genes related to cell proliferation, including those encoding cyclins, oncoproteins, growth factors, proteins involved in signal transduction, and DNA repair proteins, follow distinct temporal patterns of expression that are functionally linked to initiation of DNA replication and progression through S-phase. The timing of expression for many genes in tumor-derived HeLa cells is highly conserved when compared with normal cells. In contrast, a number of genes show growth phenotype-related expression patterns that may directly reflect loss of stringent growth control in tumor cells. Our data reveal there is a core subset of cell growth-related genes that is fundamental to cycling cells irrespective of cell growth phenotype

A modern nihilism

Presents the author's evolving views of the best current positions on certain core philosophical and psychological problems as they developed over time. These positions together suggest a skeptical or nihilist perspective modified by evolutionary psychology and contemporary philosophy that embraces our desire to live as best we can and the relative and psychological reality of values, free will and other phenomena while recognizing limitations on their foundations and our understanding. The below makes no claims to originality for most of the ideas expressed, drawing on a range of mostly unreferenced texts that will be familiar to philosophers and psychologists working in this area

Relevailles et collaborations intersectorielles : synthèse de l'atelier stratégique de mobilisation des connaissances

Dans une optique de responsabilité populationnelle, les organismes communautaires Famille (OCF) sont appelés à travailler davantage en partenariat avec les établissements de santé et de services sociaux (ÉSSS). Certains OCF offrent un service de relevailles qui consiste à offrir un soutien postnatal à domicile qui s’adapte aux besoins de chaque famille, afin d’écouter, d’encourager, d’informer et de soutenir l’organisation du quotidien. L’utilisation et les impacts de ce service demeurent largement méconnus, de même que les collaborations entourant sa mise en œuvre à même les réseaux locaux de services des ÉSSS. Entre 2013 et 2016, nous avons mené un projet de recherche collaboratif qui visait à évaluer les services de relevailles offerts par quatre OCF et les collaborations intersectorielles qu’ils partagent avec les ÉSSS en vue de consolider les services de santé et de soutien en période postnatale. Afin de présenter les résultats issus de cette étude et d’en maximiser les retombées, différents acteurs clés ont été conviés à participer à l’atelier stratégique de mobilisation des connaissances « Relevailles et collaborations intersectorielles », tenu le 4 mai 2016 à l’Université Laval. Le but de cet atelier était d’encourager les acteurs clés à se positionner par rapport à des pistes d’action visant la consolidation des services de soutien postnatal et les collaborations intersectorielles entourant l’offre de relevailles. À partir d’une présentation des principaux résultats de l’étude et de quelques pistes de consolidation préalablement sélectionnées par le Comité de suivi formé de différents utilisateurs de connaissances, les participants étaient appelés à se prononcer sur les pistes d’action à prioriser, en discutant des stratégies à préconiser pour en permettre la mise en œuvre

Development of a bilingual interdisciplinary scale assessing self-efficacy for participating in Medical Assistance in Dying

Medical Assistance in Dying (MAiD) is a complex process involving the person seeking care and their relatives. MAiD involves physical, psychosocial and spiritual needs, and consequently the involvement of an interdisciplinary team is beneficial. Therefore, updating the knowledge and skills of healthcare and social services professionals is critical. An interdisciplinary team from Laval University (Quebec, Canada) has developed a continuous training program for all health care and social services professionals who could be involved in the care of persons who request MAiD and their loved ones. It is crucial to assess whether the objectives of the continuous training program are being met, especially since this new training addresses several complex issues (legal, ethical, and clinical). Bandura's self-efficacy theory has been widely used to develop scales for assessing the impact of training programs and identifying knowledge gaps. Bandura's theory states that feeling secure in one's self-efficacy leads to self-determined motivation. Although there are various scales intended to measure self-efficacy in palliative care, none include self-efficacy for participating in the process surrounding MAiD. As a result, we aim to create a bilingual (English-French) interdisciplinary scale to assess self-efficacy for participating in the process surrounding MAiD. The scale will allow decision-makers and researchers to identify current knowledge gaps. It will also be useful for assessing the impact of current and future training programs addressing this end-of-life practice. In this work in progress, we briefly introduce the training program and the future steps in the development and validation of the scale

Disruption of AP1S1, Causing a Novel Neurocutaneous Syndrome, Perturbs Development of the Skin and Spinal Cord

Adaptor protein (AP) complexes regulate clathrin-coated vesicle assembly, protein cargo sorting, and vesicular trafficking between organelles in eukaryotic cells. Because disruption of the various subunits of the AP complexes is embryonic lethal in the majority of cases, characterization of their function in vivo is still lacking. Here, we describe the first mutation in the human AP1S1 gene, encoding the small subunit σ1A of the AP-1 complex. This founder splice mutation, which leads to a premature stop codon, was found in four families with a unique syndrome characterized by mental retardation, enteropathy, deafness, peripheral neuropathy, ichthyosis, and keratodermia (MEDNIK). To validate the pathogenic effect of the mutation, we knocked down Ap1s1 expression in zebrafish using selective antisens morpholino oligonucleotides (AMO). The knockdown phenotype consisted of perturbation in skin formation, reduced pigmentation, and severe motility deficits due to impaired neural network development. Both neural and skin defects were rescued by co-injection of AMO with wild-type (WT) human AP1S1 mRNA, but not by co-injecting the truncated form of AP1S1, consistent with a loss-of-function effect of this mutation. Together, these results confirm AP1S1 as the gene responsible for MEDNIK syndrome and demonstrate a critical role of AP1S1 in development of the skin and spinal cord

Conditional Immortalization of Human B Cells by CD40 Ligation

It is generally assumed that human differentiated cells have a limited life-span and proliferation capacity in vivo, and that genetic modifications are a prerequisite for their immortalization in vitro. Here we readdress this issue, studying the long-term proliferation potential of human B cells. It was shown earlier that human B cells from peripheral blood of healthy donors can be efficiently induced to proliferate for up to ten weeks in vitro by stimulating their receptor CD40 in the presence of interleukin-4. When we applied the same stimuli under conditions of modified cell number and culture size, we were surprised to find that our treatment induced B cells to proliferate throughout an observation period of presently up to 1650 days, representing more than 370 population doublings, which suggested that these B cells were immortalized in vitro. Long-term CD40-stimulated B cell cultures could be established from most healthy adult human donors. These B cells had a constant phenotype, were free from Epstein-Barr virus, and remained dependent on CD40 ligation. They had constitutive telomerase activity and stabilized telomere length. Moreover, they were susceptible to activation by Toll-like receptor 9 ligands, and could be used to expand antigen-specific cytotoxic T cells in vitro. Our results indicate that human somatic cells can evade senescence and be conditionally immortalized by external stimulation only, without a requirement for genetic manipulation or oncoviral infection. Conditionally immortalized human B cells are a new tool for immunotherapy and studies of B cell oncogenesis, activation, and function
