ABSTRACTDistance Education (DE) seems a way to meet the qualification requirements of contemporary societies, promoting lifelong learning anywhere. However, this mode of education often suffers from high dropout rates, notably caused by students’ isolation. The development of various communication tools offers spaces to interact and work together. To what extent do students take advantage of the proposed interaction devices to communicate and learn with others? Based on a systematic review of studies published over the last ten years addressing these types of devices established in Canada, our meta-analysis highlights that in general, students prefer to take advantage of the flexibility of DE and work alone. Thus, in most devices, there are not many students communicating. However, we will see that, when it is not only about socializing but also reflecting on a practice, interactions are much more frequent.RESUMENLa formación a distancia (FAD) parece una manera de responder a las exigencias de cualificación de las socie-dades modernas favoreciendo el aprendizaje en todo momento de la vida y en cualquier lugar. Sin embargo, este modo de formación sufre a menudo de importantes tasas de abandono causadas en parte por el aislamiento de los estudiantes. El desarrollo de diferentes herramientas de comunicación permite ofrecer a los estudiantes a distancia espacios para interactuar y trabajar juntos. ¿En qué medida los estudiantes aprovechan los dispositi-vos de interacción propuestos para comunicarse y aprender con los demás? Basado en una revisión sistemática de los estudios publicados durante los diez últimos años sobre estos tipos de dispositivos establecidos en Cana-dá, nuestro meta-análisis pone en relieve que, de manera general, los estudiantes prefieren aprovechar la flexi-bilidad de la FAD y trabajar solos. Así, en la mayoría de los dispositivos no son muchos los que comunican. Sin embargo, veremos que, cuando no se trata solamente de socializar sino también de reflexionar sobre una prácti-ca, las interacciones se multiplican. Podremos así cuestionar esos resultados a la luz de la teoría de investiga-ción.

Objective: Ketamine is a potential rapid-acting treatment for depression. Studies have suggested that the side effects are minimal and temporary, but the psychotic symptom side effects have yet to be fully examined. This study investigated whether ketamine infusion in the treatment of mood disorders is associated with increases in positive symptoms and whether these symptom effects endure over time. Methods: A systematic review and meta-analysis of studies of ketamine in the treatment of depression. Embase and Medline databases were searched for studies including (a) participants with major affective disorders, (b) 0.4 or 0.5 mg intravenously administered ketamine, (c) measurement of positive symptoms using BPRS+, and (d) a within-subject repeated-measures design with participants serving as their own baseline. Results: Seventeen studies met the inclusion criteria, comprising 458 participants. The meta-analyses examined symptom change occurring within the first 4 h, after 1 day, and after 3 days. Results showed significant BPRS+ increases within the first 30–60 min in 72% of studies, followed by a return to baseline levels. Conclusion: Peak symptom change occurred within the first hour post infusion. There are limited data to determine if ketamine is safe in the longer term, but there were no indications that psychotic symptoms re-occurred after the first hour and in the days following administration.

IntroductionTelehealth interventions have the potential of improving exacerbation and health outcomes for individuals with chronic obstructive pulmonary disease (COPD), by delivering care in between clinical visits. However, the precise impact on avoiding exacerbation and reducing the incidence of hospital readmissions remains inconclusive. This lack of knowledge on the effectiveness of telehealth for COPD care might be due to non-adherence or partial adherence to intervention programmes and/or the withdrawal of participants over the course of previous studies.ObjectivesTo conduct a systematic review of trials of telehealth interventions (including randomised control trials (RCT), crossover and pre-post studies) to: (1) estimate the acceptance, adherence and dropout rates; (2) identify the reasons for dropout from telehealth interventions among individuals with COPD; (3) evaluate the impact of trial-related, sociodemographic and intervention-related factors on the acceptance, adherence and dropout rates and (4) estimate the extent to which the acceptance, adherence and dropout rates impact outcomes in comparison with usual monitoring.Methods and analysisA systematic literature review of four databases from earliest records to November 2018 will be carried out using CINAHL, Medline (Ovid), Cochrane Library and Embase. Randomised and non-randomised control studies will be included, in addition to crossover and pre-studies post-studies comparing telehealth with standard monitoring among individuals with COPD only. Two independent reviewers will screen all relevant abstracts and full-text studies to determine eligibility, assess the risk of bias and extract the data using structured forms. If the included studies are sufficiently homogenous in terms of interventions, populations and objectives, a meta-analysis will be performed.Ethics and disseminationEthical considerations are not required for this research.Trial registration numberCRD42017078541.

Theoretical models of irony comprehension pose different hypotheses about the time-course of resolving ironic interpretation of an utterance, and propose several context-, phrase- and reader-related factors that influence the ease or difficulty of processing irony. In recent years, these factors have been examined using eye tracking, which allows a detailed analysis of time-course of reading processes. In this paper, we present a meta-analysis of the eye tracking studies on irony, and then present a systematic review of the factors that have been shown to influence the time-course of irony processing. The review will point to future directions in how eye tracking could best be applied to further develop the current theoretical views.
