Background: Autonomy is a central concept in both bioethics and rehabilitation. Bioethics has emphasized autonomy as self-governance and its application in treatment decision-making. In addition to discussing decisional autonomy, rehabilitation also focuses on autonomy as functional independence. In practice, responding to patients with diminished autonomy is an important component of rehabilitation care, but also gives rise to tensions and challenges. Our objective was to better understand the complex and distinctive ways that autonomy is understood and upheld in the context of rehabilitation care by reviewing how autonomy is discussed in the rehabilitation literature. Methods: We conducted a scoping review addressing issues of autonomy in the context of mental and physical rehabilitation. Our process followed three sequential steps. We extracted and analyzed bibliometric information. We then examined how autonomy was defined and conceptualized. Finally, we examined how the articles discussed the roles of rehabilitation health professionals in responding to patient autonomy. Findings: The articles include 16 empirical reports, 17 case studies and 30 theoretical papers. The most common conceptual accounts of autonomy drew upon principlism, rights-based and legal analyses, and relational/social approaches. We identified four broad approaches for responding to patient autonomy: supporting, promoting, respecting and advocating. Conclusion: This review helps clarify some of the ambiguities and conceptual distinctions underlying discussions and practices related to autonomy in rehabilitation. It also draws attention to a wide range of activities that health professionals can undertake with the goal of supporting, promoting, respecting and advocating for patient autonomy in rehabilitation care., Contexte: L’autonomie est un concept central tant en bioéthique qu’en réadaptation. La bioéthique a mis l’accent sur l’autonomie en tant qu’auto-gouvernance et sur son application dans la prise de décision en matière de traitement. En plus de discuter de l’autonomie décisionnelle, la réadaptation met aussi l’accent sur l’autonomie en tant qu’indépendance fonctionnelle. Dans la pratique, la prise en charge des patients en perte d’autonomie est une composante importante des soins de réadaptation, mais elle engendre aussi des tensions et des défis. Notre objectif était de mieux comprendre les façons complexes et distinctes dont l’autonomie est comprise et maintenue dans le contexte des soins de réadaptation en examinant comment l’autonomie est abordée dans la littérature sur la réadaptation. Méthodes: Nous avons effectué une étude de la portée des questions d’autonomie dans le contexte de la réadaptation mentale et physique. Notre processus s’est déroulé en trois étapes séquentielles. Nous avons extrait et analysé des informations bibliométriques. Nous avons ensuite examiné comment l’autonomie était définie et conceptualisée. Enfin, nous avons examiné la façon dont les articles traitaient du rôle des professionnels de la santé en réadaptation dans l’autonomie des patients. Résultats: Les articles comprennent 16 rapports empiriques, 17 études de cas et 30 articles théoriques. Les récits conceptuels les plus courants sur l’autonomie s’appuyaient sur le principisme, les analyses fondées sur les droits et les analyses juridiques et les approches relationnelles/sociales. Nous avons identifié quatre grandes approches pour répondre à l’autonomie du patient : le soutien, la promotion, le respect et la promotion. Conclusion: Cet examen aide à clarifier certaines des ambigüités et des distinctions conceptuelles qui sous-tendent les discussions et les pratiques liées à l’autonomie en réadaptation. Il attire également l’attention sur un large éventail d’activités que les professionnels de la santé peuvent entreprendre dans le but de soutenir, de promouvoir, de respecter et de promouvoir l’autonomie des patients dans les soins de réadaptation.

In the context of long waiting time to access rehabilitation services, a large majority of settings use referral prioritization to help manage waiting lists. Prioritization practices vary greatly between settings and there is little consensus on how best to prioritize referrals. This paper describes the prioritization processes for physiotherapy services in Québec and its potential implications in terms of equity in access to services. This is a secondary analysis of a survey of outpatient physiotherapy departments (n=98; proportion of participation was 99%) conducted in 2015 across publicly funded hospitals in Québec. In many settings, persons with acute orthopaedic conditions were prioritized while chronic conditions were given a lower priority. There were 72 different combinations of prioritization criteria used in outpatient physiotherapy departments. Variability was also observed in the type of personnel involved in the prioritization process, the number of priority levels used to rank the referrals and the source of information used to prioritize referrals. These results highlight potential issues regarding equity in access to physiotherapy services: the prioritization of persons with acute conditions to the detriment of those with chronic conditions, the lack of consensus on a fair prioritization process and the importance to adequately assess patients’ needs for treatment. Further research and interventions on prioritization criteria and processes are needed to ensure equitable access to physiotherapy services, especially in the public sector., Dans le contexte actuel de longs délais d’attente pour accéder aux services de réadaptation, la grande majorité des établissements utilisent la priorisation des demandes de référence pour aider à gérer les listes d’attente. Les pratiques de priorisation varient grandement d’un milieu à l’autre et il y a peu de consensus sur la meilleure façon de prioriser les demandes de référence. Cet article décrit les processus de priorisation de services en physiothérapie au Québec et leurs implications potentielles en termes d’équité dans l’accès aux services. Il s’agit d’une analyse secondaire d’une enquête menée en 2015 auprès des cliniques externes en physiothérapie (n=98; la proportion de participation était de 99 %) dans les hôpitaux publics du Québec. Dans de nombreux milieux, les personnes ayant une condition orthopédique aigüe étaient priorisées, tandis que les conditions chroniques recevaient une priorité moindre. Nous avons comptabilisé 72 combinaisons différentes de critères de priorisation utilisées dans les cliniques externes de physiothérapie. Nous avons également observé une variabilité dans le type de personnel impliqué dans le processus de priorisation, le nombre de niveaux de priorité utilisés pour classer les demandes de référence et la source d’information utilisée pour établir la priorisation. Ces résultats mettent en lumière des enjeux potentiels concernant l’équité dans l’accès aux services de physiothérapie : la priorisation des personnes atteintes de conditions aigües au détriment de celles atteintes de conditions chroniques, l’absence de consensus sur un processus de priorisation équitable et la nécessité d’évaluer adéquatement les besoins de traitement des patients. De futures recherches et interventions sur les critères et les processus de priorisation sont nécessaires pour assurer un accès équitable aux services de physiothérapie, en particulier dans le secteur public.

Health care services provided by workers’ compensation systems aim to facilitate recovery for injured workers. However, some features of these systems pose barriers to high quality care and challenge health care professionals in their everyday work. We used interpretive description methodology to explore ethical tensions experienced by physical therapists caring for patients with musculoskeletal injuries compensated by Workers’ Compensation Boards. We conducted in-depth interviews with 40 physical therapists and leaders in the physical therapy and workers’ compensation fields from three Canadian provinces and analyzed transcripts using concurrent and constant comparative techniques. Through our analysis, we developed inductive themes reflecting significant challenges experienced by participants in upholding three core professional values: equity, competence, and autonomy. These challenges illustrate multiple facets of physical therapists’ struggles to uphold moral commitments and preserve their sense of professional integrity while providing care to injured workers within a complex health service system.

International audience; Estrogen production by the human villous trophoblast is dependent on the biosynthetic enzyme aromatase (CYP19; CYP19A1) and is crucial for successful placental development and pregnancy outcome. Using villous cytotrophoblast cells (vCTs) freshly isolated from normal term placenta, we characterized the promoter-specific expression of CYP19A1 mRNA (derived from promoters I.1, I.4, I.8 or total transcript) and aromatase activity during villous trophoblast syncytialization. CYP19A1 mRNA levels and aromatase activity in vCTs reached a maximum after about 48 h of culture. The cAMP inducer forskolin (10 μM) and protein kinase C stimulant phorbol myristate acetate (1 μM) increased CYP19A1 mRNA levels by 1.8- and 1.6-fold, respectively, as well as inducing aromatase catalytic activity. Dexamethasone (100 nM) and vascular endothelial growth factor (5 ng/mL) decreased CYP19A1 mRNA levels, while having no effect on aromatase activity. Our results emphasize the importance of not solely studying CYP19A1 regulation and function at the mRNA level but also considering posttranslational mechanisms that alter the final catalytic activity of aromatase.

Ethics education is the cornerstone of professional practice, fostering knowledge and respect for core ethical values among healthcare professionals. Ethics is also a subject well-suited for interprofessional education and collaboration. However, there are few initiatives to gather experiences and share resources among ethics educators in rehabilitation. We thus undertook a knowledge exchange project to 1) share knowledge about ethics training across Canadian occupational and physical therapy programs, and 2) build a community of educators dedicated to improving ethics education. The objectives of this paper are to describe this interprofessional knowledge exchange project involving ethics educators (with a diversity of professional and disciplinary backgrounds) from Canadian occupational and physical therapy programs as well as analyze its outcomes based on participants’ experiences/perceptions. Two knowledge exchange strategies were employed: an interactive one-day workshop and a wiki platform. An immediate post-workshop questionnaire evaluated the degree to which participants’ expectations were met. Structured telephone interviews nine to ten months after the workshop collected participants’ perceptions on whether (and if so, how) the project influenced their teaching or led to further interprofessional collaborations. Open-ended questions from the post-workshop questionnaires and individual interviews were analyzed using qualitative methods. Of 40 ethics educators contacted, 23 participated in the workshop and 17 in the follow-up interview. Only 6 participants logged into the wiki from its launch to the end of data collection. Five themes emerged from the qualitative analysis: 1) belonging and networking; 2) sharing and collaborating; 3) changing (or not) ways of teaching ethics; 4) sustaining the network; and 5) envisioning the future of ethics education. The project attained many of its goals, despite encountering some challenges. While the wiki platform proved to be of limited benefit in advancing the project goals, the interactive format and collaborative nature of the one-day workshop were described as rewarding and effective in bringing together occupational therapy and physical therapy educators to meet, network, and share knowledge.

In vitro functional analyses of cells are widely used to investigate the molecular mechanisms involved in preeclampsia. Common cellular functions studied include adhesion, apoptosis, proliferation, migration, and invasion. At present, most researchers will use endpoint experimental assays that only allow the determination of cell function at a single time point, with the need to repeat the experiment for an alternate time point. Here, we describe an electrical impedance-based tool that allows real-time monitoring of cells, which enables the efficient assessment of multiple time points over the duration of a single experiment.

Estrogens are produced in large amounts during pregnancy, as a result of a tightly regulated cooperation between the maternal and fetal adrenal cortex, which produce androgen precursors, and the placental villous trophoblast, which transforms these precursors into estrogens. These estrogens play an important role in proper placental function, in adaptation of the mother to pregnancy, as well as in adequate fetal development. Disruption of estrogen production is associated with poor pregnancy outcomes and fetal malformation or altered fetal programming. Pregnant women may be exposed to endocrine disruptors from environmental sources or medications, and it is crucial to study the effects of such compounds on feto-placental steroidogenesis. The H295R/BeWo co-culture model offers the opportunity to study these interactions, by making it possible to evaluate the effects of chemical exposures on androgen and estrogen biosynthesis, as well as on various other aspects of feto-placental communication.

In the past, several researchers in the field of physiotherapy have asserted that physiotherapy clinicians rarely use ethical knowledge to solve ethical issues raised by their practice. Does this assertion still hold true? Do the theoretical frameworks used by researchers and clinicians allow them to analyze thoroughly the ethical issues they encounter in their everyday practice? In our quest for answers, we conducted a literature review and analyzed the ethical theoretical frameworks used by physiotherapy researchers and clinicians to discuss the ethical issues raised by private physiotherapy practice. Our final analysis corpus consisted of thirty-nine texts. Our main finding is that researchers and clinicians in physiotherapy rarely use ethical knowledge to analyze the ethical issues raised in their practice and that gaps exist in the theoretical frameworks currently used to analyze these issues. Consequently, we developed, for ethical analysis, a four-part prism which we have called the Quadripartite Ethical Tool (QET). This tool can be incorporated into existing theoretical frameworks to enable professionals to integrate ethical knowledge into their ethical analyses. The innovative particularity of the QET is that it encompasses three ethical theories (utilitarism, deontologism, and virtue ethics) and axiological ontology (professional values) and also draws on both deductive and inductive approaches. It is our hope that this new tool will help researchers and clinicians integrate ethical knowledge into their analysis of ethical issues and contribute to fostering ethical analyses that are grounded in relevant philosophical and axiological foundations.

Resume Diverses tensions emergent de l’interaction entre la physiotherapie et les agents payeurs au Quebec. Par exemple, la profession de physiotherapeute est ebranlee par plusieurs cas de fraudes et de multiplication de traitements non requis impliquant les agents payeurs. Ces pratiques frauduleuses entachent la confiance du public et consequemment le statut de professionnel des physiotherapeutes. Afin de bien comprendre les tensions actuelles, il est essentiel de situer celles-ci dans un contexte sociohistorique. Pour ce faire, une analyse thematique d’articles mediatiques canadiens a ete utilisee. Cette analyse permet une exploration des divers enjeux ethiques inherents a la tension entre les cliniques de physiotherapie et les agents payeurs. Elle permet egalement de mettre en lumiere trois facteurs sociohistoriques contributifs distincts. D’abord le contexte social d’insatisfaction des physiotherapeutes suite a la renegociation de leur contrat avec les agents payeurs semble etre un facteur ayant contribue a l’emergence des problemes rencontres. Le deuxieme facteur est l’injustice ressentie par les patients quant a l’accessibilite au systeme de soins. Finalement, le dernier facteur concerne la stigmatisation des individus indemnises par un agent payeur parapublic, surtout lorsque ces individus souffrent de maladies chroniques associees a un accident de travail. La comprehension de ces facteurs sociaux et ethiques est une premiere etape visant l’attenuation de ces tensions. Elle permettra egalement d’appuyer de futurs travaux explorant l’organisation des soins lies aux agents payeurs parapublics visant a enrayer les pratiques frauduleuses en physiotherapie.

Serotonin reuptake inhibitors (SRIs) are currently the main molecules prescribed to pregnant women that suffer from depression. Placental cells are exposed to SRIs via maternal blood, and we have previously shown that SRIs alter feto-placental steroidogenesis in an in vitro co-culture model. More specifically, serotonin (5-HT) regulates the estrogen biosynthetic enzyme aromatase (cytochrome P450 19; CYP19), which is disrupted by fluoxetine and its active metabolite norfluoxetine in BeWo choriocarcinoma cells. Based on molecular simulations, the present study illustrates that the SRIs fluoxetine, norfluoxetine, paroxetine, sertraline, citalopram and venlafaxine exhibit binding affinity for the active-site pocket of CYP19, suggesting potential competitive inhibition. Using BeWo cells and primary villous trophoblast cells isolated from normal term placentas, we compared the effects of the SRIs on CYP19 activity. We observed that paroxetine and sertraline induce aromatase activity in BeWo cells, while venlafaxine, fluoxetine, paroxetine and sertraline decrease aromatase activity in primary villous trophoblast. The effects of the paroxetine and sertraline in primary villous trophoblasts were observed at the lower doses tested. We also showed that 5-HT and the 5-HT(2A) receptor agonist 2,5-dimethoxy-4-iodoamphetamine (DOI) induced CYP19 activity. An increase in phosphorylation of serine and tyrosine and a decrease in threonine phosphorylation of CYP19 was also associated with DOI treatment. Our results contribute to better understanding how 5-HT and SRIs interact with CYP19 and may affect estrogen production. Moreover, this study suggests that alteration of placental 5-HT levels due to depression and/or SRI treatment during pregnancy may be associated with disruption of placental estrogen production.

Asthma is a complex trait, often associated with atopy. The genetic contribution has been evidenced by familial occurrence. Genome-wide association studies allowed for associating numerous genes with asthma, as well as identifying new loci that have a minor contribution to its phenotype. Considering the role of environmental exposure on asthma development, an increasing amount of literature has been published on epigenetic modifications associated with this pathology and especially on DNA methylation, in an attempt to better understand its missing heritability. These studies have been conducted in different tissues, but mainly in blood or its peripheral mononuclear cells. However, there is growing evidence that epigenetic changes that occur in one cell type cannot be directly translated into another one. In this review, we compare alterations in DNA methylation from different cells of the immune system and of the respiratory tract. The cell types in which data are obtained influences the global status of alteration of DNA methylation in asthmatic individuals compared to control (an increased or a decreased DNA methylation). Given that several genes were cell-type-specific, there is a great need for comparative studies on DNA methylation from different cells, but from the same individuals in order to better understand the role of epigenetics in asthma pathophysiology.

International audience; The effects of fluoxetine, one of the most prescribed selective serotonin-reuptake inhibitors (SSRIs) during pregnancy, and its active metabolite norfluoxetine were studied on placental aromatase (CYP19) and feto-placental steroidogenesis. Fluoxetine did not alter estrogen secretion in co-culture of fetal-like adrenocortical (H295R) and trophoblast-like (BeWo) cells used as a model of the feto-placental unit, although it induced CYP19 activity, apparently mediated by the serotonin (5-HT)2A receptor/PKC signaling pathway. Norfluoxetine decreased estrogen secretion in the feto-placental co-culture and competitively inhibited catalytic CYP19 activity in BeWo cells. Decreased serotonin transporter (SERT) activity in the co-culture was comparable to 17β-estradiol treatment of BeWo cells. This work shows that the complex interaction of fluoxetine and norfluoxetine with placental estrogen production, involves 5-HT-dependent and -independent mechanisms. Considering the crucial role of estrogens during pregnancy, our results raise concern about the impact of SSRI treatment on placental function and fetal health.

Ethical practice is an essential competency for occupational and physical therapists. However, rehabilitation educators have few points of reference for choosing appropriate pedagogical and evaluation methods related to ethics. The objectives of this study were to: (1) identify priority content to cover in ethics teaching in occupational therapy (OT) and physical therapy (PT) programmes and (2) explore useful and innovative teaching and evaluation methods.Data for this qualitative descriptive study were collected during a 1-d knowledge exchange workshop focused on ethics teaching in rehabilitation.Twenty-three educators from 11 OT and 11 PT Canadian programmes participated in the workshop. They highlighted the importance of teaching foundational theoretical/philosophical approaches and grounding this teaching in concrete examples drawn from rehabilitation practice. A wide range of teaching methods was identified, such as videos, blogs, game-based simulations and role-play. For evaluation, participants used written assignments, exams, objective structured clinical examinations and reflective journals. The inclusion of opportunities for student self-evaluation was viewed as important.The CREW Day provided ethics educators the opportunity to share knowledge and begin creating a community of practice. This space for dialogue could be expanded to international rehabilitation ethics educators, to facilitate a broader network for sharing of tacit and experiential knowledge. Implications for Rehabilitation According to the study participants, rehabilitation ethics education should include learning about foundational knowledge related to ethical theory; be grounded in examples and cases drawn from clinical rehabilitation practice; and contribute to building professional competencies such as self-knowledge and critical thinking in students. Regardless of the methods used by occupational therapy (OT) and physical therapy (PT) educators for teaching and evaluation, the value of creating spaces that support open discussion for students (e.g. protected discussion time in class, peer-discussions with the help of a facilitator, use of a web discussion forum) was consistently identified as an important facet. Educators from OT and PT programmes should work with various professionals involved in OT and PT student training across the curricula (e.g. clinical preceptors, other educators) to extend discussions of how ethics can be better integrated into the curriculum outside of sessions specifically focused on ethics. The CREW Day workshop was the first opportunity for Canadian rehabilitation ethics educators to meet and discuss their approaches to teaching and evaluating ethics for OT and PT students. Including international rehabilitation ethics educators in this dialogue could positively expand on this initial dialogue by facilitating the sharing of tacit and experiential knowledge amongst a larger and more diverse group of ethics educators.

The purpose of this study was to examine current approaches and challenges to teaching ethics in entry-level Canadian physiotherapy (PT) and occupational therapy (OT) programs.Educators responsible for teaching ethics in the 28 Canadian PT and OT programs (n = 55) completed an online survey.The quantity of ethics teaching is highly variable, ranging from 5 to 65 h. Diverse obstacles to ethics teaching were reported, relating to the organization and structure of academic programs, student issues and the topic of ethics itself. Specific challenges included time constraints, large class sizes, a lack of pedagogical tools adapted to teaching this complex subject, a perceived lack of student interest for the subject and a preference for topics related to clinical skills. Of note, 65% of ethics educators who participated in the survey did not have any specialized training in ethics.Significant cross-program variation in the number of hours dedicated to ethics and the diversity of pedagogical methods used suggests that there is little consensus about how best to teach ethics. Further research on ethics pedagogy in PT and OT programs (i.e. teaching and evaluation approaches and effectiveness of current ethics teaching) would support the implementation of more evidence-based ethics education. Implications for Rehabilitation Ethics educators in Canadian PT and OT programs are experimenting with diverse educational approaches to teach ethical reasoning and decision-making to students, including lectures, problem-based learning, directed readings, videos, conceptual maps and clinical elective debriefing, but no particular method has been shown to be more effective for developing ethical decision-making/reasoning. Thus, research on the effectiveness of current methods is needed to support ethics educators and programs to implement evidence-based ethics education training. In our survey, 65% of ethics educators did not have any specialized training in ethics. Ensuring that educators are well equipped to support the development of necessary theoretical and applied competencies can be promoted by initiatives including the creation of tailored ethics teaching and evaluation tools, and by establishing communities of practice among ethics educators. This survey identified heterogeneity in ethics teaching content, format and duration, and location within the curriculum. In order to be able to assess more precisely the place accorded to ethics teaching in PT and OT programs, careful mapping of ethics content inside and across rehabilitation programs is needed - both in Canada and internationally. These initiatives would help advance understanding of ethics teaching practices in rehabilitation.

Purpose: Physiotherapy in private practice differs from physiotherapy practised in a public setting in several ways, the most evident of which is the for-profit nature of private physiotherapy clinics; these differences can generate distinct and challenging ethical issues. The objectives of this article are to identify ethical issues encountered by physiotherapists in private practice settings and to identify potential solutions and recommendations to address these issues. Method: After a literature search of eight databases, 39 studies addressing ethical issues in a private practice context were analyzed. Results: A total of 25 ethical issues emerging from the included studies were classified into three main categories: (1) business and economic issues (e.g., conflicts of interests, inequity in a managed care context, lack of time affecting quality of care); (2) professional issues (e.g., professional autonomy, clinical judgment, treatment effectiveness, professional conduct); and (3) patients' rights and welfare issues (e.g., confidentiality, power asymmetries, paternalism vs. patient autonomy, informed consent). Recommendations as to how physiotherapists could better manage these issues were then identified and categorized. Conclusions: The physiotherapy community should reflect on the challenges raised by private practice so that professionals can be supported—through education, research, and good governance—in providing the best possible care for their patients.

Background: Experimental tools for studying the complex steroidogenic interactions that occur between placenta and fetus during human pregnancy are extremely limited. Objectives: We aimed to develop a co-culture model to study steroidogenesis by the human fetoplacental unit and its disruption by exposure to environmental contaminants. Methods: We cultured BeWo human choriocarcinoma cells, representing the villous cytotrophoblast, and H295R human adrenocortical carcinoma cells, representing the fetal unit, in a carefully adapted co-culture medium. We placed H295R cells in 24-well plates and BeWo cells on transwell inserts with or without pesticide treatment (atrazine or prochloraz) and assessed CYP19 activity and hormonal production after 24 hr of co-culture. Results: The co-culture exhibited the steroidogenic profile of the fetoplacental unit, allowing a synergistic production of estradiol and estriol (but not of estrone) of 133.3 ± 11.3 pg/mL and 440.8 ± 44.0 pg/mL, respectively. Atrazine and prochloraz had cell-type specific effects on CYP19 activity and estrogen production in co-culture. Atrazine induced CYP19 activity and estrogen production in H295R cells only, but did not affect overall estrogen production in co-culture, whereas prochloraz inhibited CYP19 activity exclusively in BeWo cells and reduced estrogen production in co-culture by almost 90%. In contrast, prochloraz did not affect estradiol or estrone production in BeWo cells in monoculture. These differential effects underline the relevance of our co-culture approach to model fetoplacental steroidogenesis. Conclusions: The co-culture of H295R and BeWo cells creates a unique in vitro model to reproduce the steroidogenic cooperation between fetus and placenta during pregnancy and can be used to study the endocrine-disrupting effects of environmental chemicals.

Context: There is growing recognition of the importance of knowledge translation activities in physical therapy to ensure that research findings are integrated in clinical practice, and increasing numbers of knowledge translation interventions are being conducted. Although various frameworks have been developed to guide and facilitate the process of translating knowledge into practice, these tools have been infrequently used in physical therapy knowledge translation studies to date. Problem and recommendation: Knowledge translation in physical therapy implicates multiple stakeholders and environments, and involves numerous steps. In light of this complexity, the use of explicit conceptual frameworks by clinicians and researchers conducting knowledge translation interventions is associated with a range of potential benefits. In this article, we argue that such frameworks are important resources to promote the uptake of new evidence in physical therapy practice settings. We identify four key benefits associated with the use of conceptual frameworks in designing and implementing knowledge translation interventions. We also consider limits related to their use. We then evaluate a sample of five conceptual frameworks and consider how they address common barriers to knowledge translation in physical therapy. The goal of this analysis is to provide guidance to physical therapists seeking to identify a framework to support the design and implementation of a knowledge translation intervention. Finally, we illustrate the use of a conceptual framework through a case example. Conclusion: Increased use of conceptual frameworks can have a positive impact on the field of knowledge translation in physical therapy and support the development and implementation of robust and effective knowledge translation interventions that help span the research-practice gap.

The recent introduction of master's level curricula for Occupational Therapy (OT) and Physiotherapy (PT) training programs in Canada raises both challenges and opportunities to address ethical issues during professional training. This study evaluated the inclusion of ethics content in course descriptions and course calendars in order to develop a preliminary understanding of how rehabilitation ethics is taught in Canadian universities.We reviewed the ethics content in the online curricula of 27 Canadian rehabilitation programs (OTPT). Courses addressing ethical issues were identified through keyword searches, and were then subjected to both quantitative and textual descriptive analyses.The mean proportion of credits allotted to courses that included ethics terminology was 5.9% (SD = 1.4) for OT and 6.5% (SD = 4.8) for PT (p = 0.69). The most common terms in the course descriptions were "ethics/ethical" followed by "legal", "professionalism", "deontology" and "regulatory". Textual analysis revealed eight course topics, the most frequent being: standards of practice, ethical decision-making, clinical courses and mediation/communication.With the growing recognition and status of OT and PT in the healthcare system, and corresponding shifts in how professionals are being trained, it is crucial to assess and reflect upon the place accorded to and manner of teaching ethics. Implications for Rehabilitation Ethics training in rehabilitation programs With the evolving recognition of OT and PT professions within the healthcare system, and corresponding shifts in how future professionals are trained, it is crucial to assess the place accorded to teaching ethics. In Canadian OT and PT programs, ethics content is most commonly included in broad courses related to standards of practice and not in specific ethics courses. Careful attention is needed to ensure that OT and PT students receive sufficient ethics training that is well aligned with their future practice context to support them to competently address the ethical issues that they will encounter in clinical practice. In addition, OT and PT professionals would benefit from the development of continuing education activities that target ethical issues relevant to their practice.

Les modalites electro-therapeutiques font partie integrante de l’arsenal d’intervention en physiotherapie/kinesitherapie. Ces modalites incluent les formes d’energie thermique (chaleur et cryotherapie), electrique (courants TENS, stimulation neuromusculaire, etc.), acoustique (ultrasons, ondes de choc radiales) et electromagnetique (LASER). Face a un patient presentant un probleme clinique, la selection de ces modalites se base evidemment sur le raisonnement clinique (RC) du therapeute. Le RC est un processus complexe d’analyse des donnees et de reflexion du therapeute menant a une prise de decision appropriee en fonction du contexte, en vue de la resolution d’un probleme de sante (Higgs 2000 et Nendaz et al. 2005). Dans le cas de la selection des modalites electro-therapeutiques, ce raisonnement est un processus complexe qui doit tenir compte a la fois du type de probleme, du stade d’evolution ainsi que des ressources disponibles. Par ailleurs, ce raisonnement se base sur les preuves scientifiques et l’experience clinique. Les preuves scientifiques supportent l’utilisation des modalites electro-therapeutiques comme adjuvants aux traitements physiotherapiques. Selon l’experience clinique d’experts, une premiere demarche de RC est la categorisation des problemes selon qu’ils soient principalement lies a la douleur, a l’inflammation, a des lesions tissulaires ou a la faiblesse. Les evidences corroborent les effets benefiques sur ces differentes problematiques. Cependant, ces effets varient en fonction de plusieurs facteurs, dont les parametres d’application des modalites. A l’issue de cette presentation, les participants seront capables d’identifier les modalites electro-therapeutiques adjuvantes les plus pertinentes pour des problemes frequemment traites en physiotherapie/kinesitherapie. La presentation proposee demontrera des outils visant a orienter le raisonnement clinique des participants dans la selection des modalites d’electrotherapie les plus pertinentes dans un cas donne. Ces outils seront bases sur les preuves scientifiques les plus recentes pour la selection et la priorisation des modalites physiques et electro-therapeutiques en readaptation ainsi que pour le choix des parametres a utiliser.

International audience; Up to 6.2% of pregnant women undergo antidepressant treatment with selective serotonin-reuptake inhibitors (SSRIs). SSRIs, which act on the serotonin transporter (SERT), have been associated with adverse effects on pregnancy. However, the action of one of the most prescribed SSRIs, fluoxetine, on the endocrine function of the feto-placental unit and placental serotonin transport has never been studied. Using a co-culture of BeWo (human trophoblast-like) and H295R (human fetal-like adrenocortical) cells, we studied the effects of fluoxetine and its active metabolite norfluoxetine on feto-placental estrogen biosynthesis and serotonin transport.
