Facilitating effective group collaboration is a major challenge in contemporary educational and professional contexts, and digital environments may support this goal by structuring collaborative processes through explicit instructions. The present experimental study examined the effects of collaboration instructions based on constructive controversy principles on group collaboration. These instructions were delivered via a digital environment during an initial training task. Both immediate effects on the training task and delayed effects on a subsequent transfer task were assessed. Measures included group performance (synergy), perceptions of group processes (epistemic and relational conflict regulation), perceived social skills, and communication behaviors. Results indicated that the collaboration instructions positively affected conflict regulation processes and group synergy during the training task only. In addition, perceived social skills and communication behaviors increased from the training task to the transfer task, but only for groups that received the instructions. Overall, these findings suggest that providing structured collaboration instructions through a digital environment can enhance group collaboration and, to a lesser extent, support the development of social skills and communication behaviors across tasks.

Améliorer la qualité de vie des patients pendant et après leur maladie est devenu un objectif majeur dans le domaine de la cancérologie. Le but de cette étude était d’analyser l’impact de séances de gestion de stress sur l’amélioration de la qualité de vie à la sortie de patients opérés d’un cancer colorectal. Les patients opérés d’un cancer colorectal ont été randomisés entre un groupe n’ayant pas de séance de gestion de stress et un groupe ayant bénéficié de séances de stress en périopératoire au sein d’un programme de réhabilitation améliorée après chirurgie (RAAC). Les critères ont été évalués à partir de questionnaires avant, pendant, et à la sortie d’hospitalisation. Le bien-être, le score de fatigue, la qualité de vie ont été évalués respectivement par l’échelle de mesure des manifestations du bien-être psychologique (EMMBEP), par l’inventaire multidimensionnel de la fatigue (MFI), l’échelle Functional Assessment of Cancer Therapy-Colorectal (FACT-C). La douleur et le sommeil ont été évalués l’aide d’une échelle visuelle analogique. L’efficacité des séances de gestion de stress a été évaluée à la sortie, et la satisfaction des patients a été évaluée à 1 mois. La durée d’hospitalisation et les complications ont été comparées entre les 2 groupes. Un total de 150 patients ont été inclus dans l’étude dont 74 dans le groupe contrôle et 76 dans le groupe expérimental. Quatre patients ont été exclus car non opérés. Les résultats ne montrent pas de différence significative entre les deux groupes sur le plan démographique. Les séances de gestion de stress n’avaient pas amélioré la qualité de vie des patients à la sortie. Le bien-être préopératoire était inversement corrélé au score de fatigue MFI ( p < 0,001). La durée d’hospitalisation et les complications postopératoires n’étaient pas influencées par les séances de gestion de stress. Les séances de gestion du stress en périopératoire d’un cancer colorectal n’ont pas permis de montrer un impact positif sur la qualité de vie à la sortie d’hospitalisation. De plus, la durée d’hospitalisation ou le taux de complications postopératoires n’ont pas été influencés par les séances de gestion de stress. Improving patients’ quality of life during and after their illness has become a major objective in the field of oncology. The aim of this study was to analyze the impact of stress management sessions on improving quality of life upon discharge in patients undergoing colorectal cancer surgery. Patients undergoing colorectal cancer surgery were randomized between a group that received perioperative stress management sessions as part of an enhanced rehabilitation after surgery (ERAS) program and a group that did not. Outcomes were assessed using questionnaires before, during, and at discharge from hospitalization. Well-being, fatigue score, and quality of life were assessed using the Manifestations of Psychological Well-Being Scale (EMMBEP), the Multidimensional Fatigue Inventory (MFI), and the FACT-C scale (Functional Assessment of Cancer Therapy-Colorectal), respectively. Pain and sleep were assessed using a visual analog scale. The effectiveness of stress management sessions was evaluated at discharge, and patient satisfaction was assessed at one month. Length of hospital stay and complications were compared between the two groups. Of a total of 150 patients who were randomized in the study, four patients were excluded because they did not undergo surgery, leaving 74 in the control group and 76 in the experimental group. The results showed no statistically significant difference between the two groups in terms of demographics. Stress management sessions did not improve patients’ quality of life at discharge. Preoperative well-being was inversely correlated with the MFI fatigue score ( P < 0.001). Length of hospital stay and postoperative complications were not influenced by stress management sessions. Perioperative stress management sessions for colorectal cancer did not demonstrate a positive impact on quality of life at hospital discharge, and neither length of hospital stay nor post-operative complication rates were influenced by stress management sessions.

ABSTRACT The serotonin 5-HT 7 receptor (5-HT 7 R), a member of the rhodopsin-like family of G protein-coupled receptors (GPCRs) is highly expressed in the central nervous system (CNS) and represents a promising target for treating CNS disorders such as sleep disturbances, migraine, neuropsychiatric conditions, and neuropathic pain. Owing to its therapeutic potential, extensive efforts have focused on developing selective 5-HT 7 R ligands. In the last decades, biased signalling has emerged as a key concept in GPCR pharmacology as biased ligands can stabilize specific active states of the receptor and trigger selective activation of downstream signaling pathways. In this context, we recently identified two biased 5-HT 7 R ligands, Serodolin and MOA51, from different chemical series. Here, we aimed to compare the pharmacological and safety profiles of these ligands and to assess their effect on pain-related behaviors and spinal neuroinflammation. In inflammatory pain models (acid acetic writhing, formalin and CFA tests), both serodolin and MOA51 effectively attenuated pain responses to a similar extend. Furthermore, in neuropathic pain models, spinal nerve injury (SNI) and Cuff model, both ligands reversed mechanical allodynia. Interestingly, unlike pregabalin, a clinically used reference drug, neither Serodolin nor MOA51 induced apparent tolerance after 10 consecutive days of administration. Treatment with these 5-HT 7 R ligands also reduced spinal microglial and attenuated neuronal hyperactivity in the spinal cord. Altogether these findings highlight the potential of 5-HT 7 R-biased ligands as promising analgesic candidates capable of modulating neuroinflammatory processes and mitigating both inflammatory and neuropathic pain.

BackgroundEndometriosis is a chronic disease that affects 1 in 10 women worldwide. The disease affects patients’ daily life at physical, psychological, and social levels. In recent years, the management of this disease has evolved, thanks in particular to the emergence of digital technologies and associated interventions. However, despite their growing use, there seems to be no systematic review of their development, design, and efficacy.ObjectiveA systematic review was conducted with the aim of characterizing the development process, design, and effectiveness of interventions using a digital tool for endometriosis.MethodsA total of 7 databases (MEDLINE, APA PsycArticles, Academic Search Premier, Psychology and Behavioral Sciences Collection, APA PsycInfo, SocINDEX, and SPORTDiscus) were searched to identify relevant articles published between 2010 and 2024. The articles selected were analyzed using a methodological framework specific to the development of digital health interventions (Design and Evaluation of Digital Health Interventions [DEDHI]), consisting of 4 phases: preparation (phase 1, specific to application development), optimization (phase 2, dedicated to identifying the best intervention configurations), evaluation (phase 3, aiming to confirm the effectiveness of the intervention), and implementation (phase 4, implementing and updating the intervention on a large scale).ResultsA selection of 10 articles was made from the 381 studies retrieved from the databases. Among these 10 studies, 6 distinct digital health interventions were identified. The interventions based on digital devices produced physical and psychological benefits. Analysis using the DEDHI framework showed (1) a disparity in the responses to the different phases (ie, 9/10, 90% of studies responding to phase 1; 3/10, 30% to phase 2; 4/10, 40% to phase 3; and 2/10, 20% to phase 4) and (2) a variability in the completion of the evaluation criteria ranging from 10% (1/10) to 80% (8/10) in phase 1, 0% (0/13) to 77% (10/13) in phase 2, 0% (0/10) to 80% (8/10) in phase 3, and finally 0% (0/13) to 77% (10/13) in phase 4. The objectives of these digital interventions were to support pain management (5/6, 83%), to provide information about the disease and strategies for managing it (4/6, 67%), and to provide psychosocial support (2/6, 33%).ConclusionsThis systematic review highlights an emerging literature, limited regarding the use of digital technology in the management of endometriosis, and heterogeneous concerning the methodologies used. This variability limits the generalizability of the results and requires a nuanced interpretation of the available data. However, the results of this review have demonstrated the value of digital technology–based interventions to support endometriosis, while highlighting the importance of a methodological framework to structure their development to optimize patient support.

Crises in the operating room, often resulting from human factors, endangers patient safety. Simulation-based training to develop non-technical skills shows promise in managing these crises. This review examines the simulation techniques, targeted healthcare professionals, non-technical skills, crisis scenarios, and evaluation metrics used in operating room crisis management training. Systematic review. MEDLINE, APA PsycInfo and Web of Science databases were searched for peer-reviewed articles published between January 2004 and March 2024. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The review protocol has been registered on the Open Science Framework (OSF) (https://osf.io/7bsc8). The inclusion criteria were as follows: (1) The study population comprised healthcare and medical professionals or students; (2) the intervention involved a simulated learning or training experience; (3) the outcomes focused on non-technical skills or crew resource management; (4) the training setting was the operating room (simulated or real); and (5) the learning scenarios depicted a crisis or an adverse event. This systematic review identified 29 eligible articles. The findings highlight the predominance of high-fidelity simulations, primarily targeting medical staff rather than nurses or other healthcare professionals. Training focused on communication, teamwork, situation awareness, problem solving, and decision making, with scenarios mostly addressing patient deterioration. Assessments reached up to Kirkpatrick's Level 3, demonstrating a positive training impact through learners' reactions and learning metrics rather than behavior and organizational results. Despite their effectiveness, current training practices exhibit limitations. Incorporating nurses and other paramedical staff in interprofessional training, as well as emphasizing team-related scenarios and evaluating behavioral changes in practice, could enhance training effectiveness. This has implications for interprofessional healthcare education and skills transfer to real-world settings, ultimately improving patient safety.

Abstract BackgroundPrevious research has demonstrated that quizzing can improve self‐regulation processes and learning performances. However, it remains unclear whether quizzes in multimedia material bring similar benefits, and whether interindividual differences such as working memory capacity (WMC) modulate quizzing effects.AimsThis study aimed to examine the effects of embedded quizzes (multiple quizzes within the learning sequence) with feedback during a multimedia learning sequence on self‐regulated processing (monitoring and control) and learning performances on repeated (material already tested) and new (untested) questions, and possible WMC moderation on performances.Sample and MethodsParticipants were 59 students who learned a multimedia neuroscience course module in either a no‐quiz or embedded quizzes condition. With regard to self‐regulated processing, control was assessed with eye‐tracking measures (fixation durations and transitions between texts and illustrations), and monitoring by comparing self‐reported judgements of learning with actual performances (calibration). At the end, students' WMC was measured, and learning performances were assessed with repeated and new questions.ResultsQuizzing improved learning performances on repeated and new questions, and enhanced monitoring (better calibration). Students with low WMC benefited more from quizzing for new questions than those with high WMC. However, contrary to our hypothesis, the embedded quizzes group allocated less time to the learning than the no‐quiz group.ConclusionsEmbedded quizzes are relevant tools to help students recalibrate their monitoring process and foster more effective self‐regulated learning. Results confirm that the use of quizzes can be recommended to improve the learning of multimedia material, especially among students with low WMC.
