[Behavioral activation and depression: a contextual treatment approach]. / Activation comportementale et dépression : une approche de traitement contextuelle.

Depression is a widespread psychological disorder that affects approximately one in five North American. Typical reactions to depression include inactivity, isolation, and rumination. Several treatments and psychological interventions have emerged to address this problematic. Cognitive behavioural therapies have received increasingly large amounts of empirical support. A sub-component of cognitive behavioural therapy, behavioural activation, has been shown to in itself effectively treat symptoms of depression. This intervention involves efforts to re-activate the depressed client by having them engage in pleasant, gratifying, leisure, social, or physical activities, thereby counteracting the tendency to be inactive and to isolate oneself. Clients are guided through the process of establishing a list of potentially rewarding social, leisure, mastery-oriented or physical activities, to then establish a gradual hierarchy of objectives to be accomplished over the span of several weeks. Concrete action plans are devised, and solutions to potential obstacles are elaborated. The client is the asked to execute the targeted objective and to record their mood prior to and following the activity. Behavioural activation effectively reverses the downward spiral to depression. Interestingly, studies show that behavioural activation has a positive effect on cognitive activities. It has been shown to reduce rumination and favour cognitive restructuring, without requiring cognitively-based interventions. The advantage of this treatment is therefore that it is simpler to administer in comparison to full-packaged cognitive behavioural therapies, it requires a lesser number of sessions and can be disseminated in a low-intensity format. This article begins by summarizing the origins of the behavioural model of depression, which serves as a basis to the understanding of behavioural activation. This is followed by a detailed explanation of the different phases involved in a behavioural activation intervention. Empirical support for behavioural activation is then presented in regards to depression as well as comorbid physical and psychological health problems. The results of meta-analyses and randomized controlled trials are presented. Behavioural activation is then discussed within the framework of third-wave therapies, discussing the potential role of mindfulness in behavioural activation objectives. Specifically, it is suggested that mindfulness, although not necessarily directly addressed in behavioural activation interventions, is an integral part of this intervention as clients are asked to record their mood and activities and to become cognizant of the relationship between their symptoms of depression and the participation in activities that provide positive reinforcement. This favours self-awareness and allows clients to realize the impact of their actions on their physical and psychological states. In engaging in self-observation and self-recording, and in participating in a variety of tasks and activities, clients are indirectly encouraged to focus on the here and now rather that to succumb to the depressive tendency that is to ruminate. Suggestions are made as to how therapists can include mindfulness-based activities in the behavioural activation hierarchy. It is hypothesized that, due to the calming effect of mindfulness practices on the nervous system, incorporating mindfulness-based activities-such as yoga, tai chi, Qi Gong, or meditation-could for some people enhance the efficacy of behavioural activation interventions and foster a greater sense of well-being. The article concludes by discussing issues that should be addressed in future research. It is suggested that future studies on behavioural activation explore the impacts of incorporating mindfulness-based activities in the behavioural activation hierarchy in comparison to a traditional hierarchy limited to the accomplishment of gratifying or mastery-oriented tasks, social outings, leisure activities and physical activity.

Understanding the challenges related to breastfeeding education and barriers to curricular change: a systems perspective for transforming health professions education.

Objectives: A majority of women and families wish that their babies be breastfed. However, too many still receive insufficient or inappropriate initial care from health professionals (HPs) who have limited breastfeeding (BF) competencies. We investigated barriers and potential solutions to improve the undergraduate training programs for various HPs. Methods: Focus groups were carried out in three universities in Quebec and one in Ontario (Canada), with 30 faculty and program directors from medicine, midwifery, nursing, nutrition, and pharmacy. Discussions were subjected to thematic content analysis, before being validated in a strategic planning workshop with 48 participants from the same disciplines, plus dentistry and chiropractic. Findings: Substantive improvements of undergraduate training programs for BF could be obtained by addressing challenges related to the insufficient, or lack of, (i) interactions among various HPs, (ii) opportunities for practical learning, (iii) specific standards to guide course content, (iv) real-life experience with counselling, and (v) understanding of the influence of attitudes on professional practice. Several potential solutions were proposed and validated. The re-interpretation of the results in light of various literature led to an emerging framework that takes a systems perspective for enhancing the education of HPs on BF. Conclusions: To improve the education of HPs so as to enable them to provide relevant support for future mothers, mothers and their families, solutions need to be carried out to address challenges in the health system, the education system as well as regarding the curricular change process.

Objectifs: La majorité des femmes et des familles souhaitent que leur bébé soit allaité. Toutefois, plusieurs ne reçoivent pas un soutien adéquat de la part de professionnels de la santé (PS) qui ont des compétences limitées en allaitement. Nous avons étudié les barrières et les solutions potentielles en vue de rehausser la formation initiale de divers PS. Méthodes: Des groupes de discussion ont été organisés dans trois universités du Québec et une en Ontario (Canada) avec 30 directeurs de programmes et membres du corps professoral en médecine, pratique sage-femme, sciences infirmières, nutrition et pharmacie. Les discussions ont fait l'objet d'une analyse de contenu thématique laquelle fut ensuite validée dans un atelier de planification stratégique avec 48 participants des mêmes disciplines auxquelles se sont ajoutées dentisterie et chiropratique. Résultats: Des améliorations substantielles des compétences en allaitement dans les programmes de formation initiale pourraient être obtenues en travaillant sur les défis associés à l'insuffisance, ou à l'absence de, (i) interactions entre les divers PS, (ii) opportunités d'apprentissages pratiques, (iii) normes spécifiques pour guider les contenus de cours, (iv) expériences réelles avec le counseling, et (v) compréhension de l'influence des attitudes sur la pratique professionnelle. La ré-interprétation des résultats à la lumière de la littérature a fait émerger un cadre conceptuel avec une perspective systémique pour guider le rehaussement de la formation en allaitement des divers PS. Conclusions: Afin d'améliorer la formation des PS pour qu'ils/elles puissent fournir un soutien pertinent aux futures mères, aux mères et à leurs familles, des solutions visant à la fois les défis dans le système de santé, dans le système d'éducation et dans le processus de changement curriculaire doivent être mises en œuvre.

Kinesiophobia and physical therapy-related pain in musculoskeletal pain: A national multicenter cohort study on patients and their general physicians.

INTRODUCTION: Physical therapy (PT) represents a major approach in musculoskeletal (MSK) pain. This study aimed to assess kinesiophobia, its impact and management, in patients with MSK pain treated by PT. METHODS: A national multicenter, prospective study was conducted in France in patients with MSK pain referred to PT. Kinesiophobia was scored with the Tampa Scale of Kinesiophobia (TSK). Pain, satisfaction, analgesic intake and acceptability were assessed at the initial visit, at the 5th PT session, and at the end of PT. RESULTS: A total of 700 consecutive outpatients with MSK pain, 54.5% female, referred to PT were recruited by 186 GPs: 501 had significant levels of kinesiophobia (TSK score>40). Patients with kinesiophobia were significantly older, with less physical activity, more pain and less acceptability. Patients from GPs presenting with kinesiophobia had both higher pain and kinesiophobia levels. After 5 PT sessions, global satisfaction was significantly higher in patients without kinesiophobia. A significant increase of PT satisfaction was observed in patients who had been given preventive analgesics before PT sessions, in 25.6% of patients. Independent predictors for specific management of PT-induced pain were: patient's kinesiophobia (OR=2.02 [1.07-3.82]), current analgesics treatment (OR=2.05 [1.16-3.63]), GP with postgraduate course on pain (OR=2.65 [1.29-5.43]), GP's independent practice (OR=1.88 [1.01-3.48]). CONCLUSION: Kinesiophobia is frequent in patients with MSK pain, is associated to GPs' kinesiophobia and decreases satisfaction of physical therapy. Preventive analgesic treatment before PT sessions improves patients' satisfaction and should be proposed to improve MSK pain management.

Electronic sorting and recovery of single live cells from microlitre sized samples.

Sorting and recovering specific live cells from samples containing less than a few thousand cells have become major hurdles in rare cell exploration such as stem cell research, cell therapy and cell based diagnostics. We describe here a new technology based on a microelectronic chip integrating an array of over 100,000 independent electrodes and sensors which allow individual and parallel single cell manipulation of up to 10,000 cells while maintaining viability and proliferation capabilities. Manipulation is carried out using dynamic dielectrophoretic traps controlled by an electronic interface. We also demonstrate the capabilities of the chip by sorting and recovering individual live fluorescent cells from an unlabeled population.

Microtubule self-organisation by reaction-diffusion processes in miniature cell-sized containers and phospholipid vesicles.

Under appropriate conditions, in vitro microtubule preparations self-organise over macroscopic distances by a process of reaction and diffusion. To investigate whether such self-organisation can also occur in objects as small as a cell or an embryo we carried out experiments in miniature containers of cellular dimension. When assembled under self-organising conditions in wells of 120-500 microm, microtubules developed organised structures. Self-organisation is strongly affected by shape, being highly favoured by elongated forms. In wells of more complex shape, geometrical factors may either oppose or strengthen one another and so inhibit or reinforce self-organisation. Microtubules were also assembled within phospholipid vesicles of 2-5 microm diameter. Under self-organising conditions, we observed large shape changes from spheroids to long tubes (50-100 microm) and intertwined coils. We conclude that self-organisation of microtubules by reaction-diffusion processes can occur in containers of cellular dimensions and is capable of strongly deforming the cellular membrane.

Reasons for non-intensification of treatment in people with type 2 diabetes receiving oral monotherapy: Outcomes from the prospective DIAttitude study.

OBJECTIVES: To describe the management of glucose-lowering agents in people with type 2 diabetes initially on oral monotherapy, cared for by French general practitioners, and to identify reasons underlying treatment non-intensification. METHODS: People with type 2 diabetes on oral monotherapy were recruited by general practitioners and followed-up over 12 months. Patient characteristics, HbA1c, and glucose-lowering treatments were recorded electronically. Management objectives and reasons for treatment non-intensification were solicited from the general practitioners. RESULTS: A total of 1212 patients were enrolled by 198 general practitioners; 937 patients (mean age 68 years) were treated with oral monotherapy, and 916 patients had at least two successive HbA1c values recorded. Of these, 390 patients (43%) had HbA1c≥6.5% on both occasions, and 164/390 (42%) had their treatment intensified. The 226 patients whose treatment was not intensified were older (69±11 years vs. 66±12 years, P=0.02) and had better glycaemic control at study inclusion (6.9%±0.6 vs. 7.3%±0.8, P<0.0001) than treatment intensified patients. Among uncontrolled patients, there were no differences in general practitioner treatment objectives at inclusion for treatment intensified and non-intensified patients; the main reason given by general practitioners for non-intensification was that the patient had an adequate HbA1c (66%). HbA1c did exceed the 6.5% target, but was less than 7.0% in 69% of cases. CONCLUSIONS: General practitioners showed a patient-centred approach to treatment, but clinical inertia was apparent for 31% of the uncontrolled patients.

Behavioural activation for depression: efficacy, effectiveness and dissemination.

BACKGROUND: Depression being a prevalent psychobiological disorder across the world, there is a need to identify effective, evidence-based treatments that are time and cost-effective in an effort to increase the population's accessibility to treatments. Low-intensity interventions, such as guided self-help treatments, hold promise for the dissemination of evidence-based treatments. Behavioural activation, a component of cognitive-behavioural therapy, is receiving increasing attention and empirical support as a stand-alone psychological treatment for depression. This article reviews behavioural activation's theoretical foundations and efficacy in light of determining its potential as a low-intensity intervention. METHOD: A systematic review of articles on low-intensity behavioural activation interventions for depression was conducted using the PsychInfo, Medline and Embase databases. Behavioural activation's potential for dissemination as a guided self-help treatment is discussed and future avenues of research are stressed. LIMITATIONS: Studies on the efficacy of behavioural activation as a guided self-help treatment are very limited to date and there are significant variations among existing studies. CONCLUSIONS: Based on the research literature, it can be concluded that behavioural activation could be a viable option as a low-intensity guided self-help psychological treatment for mild to moderate depression. Further research is required to better understand the optimal parameters and client-therapist characteristics of this form of low-intensity intervention.

From dispositional affect to academic goal attainment: the mediating role of coping.

The purpose of this research was to examine a mediation model in which coping was hypothesized to mediate the relationship between positive and negative dispositional affect and academic goal attainment. At Time 1, a sample of 217 undergraduate students completed measures of dispositional affect and set a personal academic goal. At Time 2, 4 weeks later, they completed a follow-up questionnaire assessing their coping strategies and degree of goal attainment. Results from structural equation modeling revealed that task-oriented coping significantly mediated the relationship between dispositional positive affect and goal attainment. Results also supported disengagement-oriented coping as a mediator in the relationship between dispositional negative affect and goal attainment. These findings highlight the role of coping as an important process in the relationship between dispositional affect and goal attainment.

BIOTEX--biosensing textiles for personalised healthcare management.

Textile-based sensors offer an unobtrusive method of continually monitoring physiological parameters during daily activities. Chemical analysis of body fluids, noninvasively, is a novel and exciting area of personalized wearable healthcare systems. BIOTEX was an EU-funded project that aimed to develop textile sensors to measure physiological parameters and the chemical composition of body fluids, with a particular interest in sweat. A wearable sensing system has been developed that integrates a textile-based fluid handling system for sample collection and transport with a number of sensors including sodium, conductivity, and pH sensors. Sensors for sweat rate, ECG, respiration, and blood oxygenation were also developed. For the first time, it has been possible to monitor a number of physiological parameters together with sweat composition in real time. This has been carried out via a network of wearable sensors distributed around the body of a subject user. This has huge implications for the field of sports and human performance and opens a whole new field of research in the clinical setting.
