Digital Interventions for Emotion Regulation in Children and Early Adolescents: Systematic Review and Meta-analysis.

BACKGROUND: Difficulties in emotion regulation are common in adolescence and are associated with poor social and mental health outcomes. However, psychological therapies that promote adaptive emotion regulation may be inaccessible and unattractive to youth. Digital interventions may help address this need. OBJECTIVE: The aim of this systematic review and meta-analysis was to synthesize evidence on the efficacy, feasibility, and acceptability of emotion regulation digital interventions in children and early adolescents aged 8 to 14 years. METHODS: Systematic searches of Web of Science, MEDLINE, PsycINFO, EMBASE, Education Resources Information Centre, ACM Digital Library, and IEEE Xplore up to July 2020 identified 39 studies, of which 11 (28%) were included in the meta-analyses (n=2476 participants). A bespoke tool was used to assess risk of bias. RESULTS: The studies evaluated digital games (27/39, 69%), biofeedback (4/39, 10%), virtual or augmented reality (4/39, 10%), and program or multimedia (4/39, 10%) digital interventions in samples classified as diagnosed, at risk, healthy, and universal. The most consistent evidence came from digital games, which reduced negative emotional experience with a small significant effect, largely in youth at risk of anxiety (Hedges g=-0.19, 95% CI -0.34 to -0.04). In general, digital interventions tended to improve emotion regulation, but this effect was not significant (Hedges g=0.19, 95% CI -0.16 to 0.54). CONCLUSIONS: Most feasibility issues were identified in diagnosed youth, and acceptability was generally high across intervention types and samples. Although there is cause to be optimistic about digital interventions supporting the difficulties that youth experience in emotion regulation, the predominance of early-stage development studies highlights the need for more work in this area.

Toward an Integrated Model of Supportive Peer Relationships in Early Adolescence: A Systematic Review and Exploratory Meta-Analysis.

Supportive peer relationships (SPR) are crucial for mental and physical health. Early adolescence is an especially important period in which peer influence and school environment strongly shape psychological development and maturation of core social-emotional regulatory functions. Yet, there is no integrated evidence based model of SPR in this age group to inform future research and practice. The current meta-analysis synthetizes evidence from 364 studies into an integrated model of potential determinants of SPR in early adolescence. The model encompasses links with 93 variables referring to individual (identity, skills/strengths, affect/well-being, and behavior/health) and environmental (peer group, school, family, community, and internet/technology) potential influences on SPR based on cross-sectional correlational data. Findings suggest the central importance of identity and social-emotional skills in SPR. School environment stands out as a compelling setting for future prevention programs. Finally, we underscore an alarming gap of research on the influence of the virtual and online environment on youth's social realm given its unquestionable importance as a globally expanding social interaction setting. Hence, we propose an integrated model that can serve as organizational framework, which may ultimately lead to the adoption of a more structured and integrated approach to understanding peer relationship processes in youth and contribute to overcoming marked fragmentation in the field.

Health Technology Assessment of Carbon-ion Beam Radiotherapy: A Systematic Review of Clinical Effectiveness and Safety for 54 Oncological Indications in 12 Tumour Regions.

BACKGROUND/AIM: Due to the unique physical dose distribution of carbon-ion radiotherapy (CIRT), CIRT can be regarded as a novel tumour irradiation technique - potentially advantageous for various tumour types. Yet it is unclear in how far, superiority or inferiority can be claimed when comparing CIRT to standard irradiation. This study aimed to assess the scientific evidence regarding the effectiveness and safety of CIRT. MATERIALS AND METHODS: A systematic literature review was performed using the European Network for Health Technology Assessment (EUnetHTA) Core Model® for rapid relative effectiveness assessment. The literature search for clinical outcome studies on CIRT was performed using four databases [Cochrane (Central), Centre for Research and Dissemination (CRD), Embase and OVID MEDLINE]. The Cochrane Risk of Bias Tool (for randomised controlled trials) and the Institute of Health Economics (IHE-18) Checklist (for observational studies) were used to assess the risk of bias of the included studies. The evidence synthesis was restricted to 54 oncological indications in 12 broad tumour regions and studies with a low or moderate risk of bias, published between 2005 and 2017. RESULTS: Twenty-seven studies were eligible for the qualitative synthesis of the evidence regarding the effectiveness and safety of CIRT: One randomised controlled trial that primarily focused on the feasibility of CIRT, three case-control studies, three before- and after- studies with a focus on quality of life, and 20 further studies of case series. Overall, insufficient scientific evidence was found for superiority or inferiority of CIRT when compared to standard irradiation for 13/54 oncologicaI indications in 7/12 tumour regions (skull base tumours, brain cancer, cancer in the ear-nose-throat region, bone and soft-tissue tumours, lung cancer, prostate cancer, gastrointestinal tumours). No scientific evidence was found for the remaining 41/54 oncological indications. CONCLUSION: CIRT is undoubtedly, theoretically, a promising cancer treatment. To date, however, it lacks randomised controlled trials assessing the long-term effectiveness and harms associated with the use of CIRT. CIRT must be considered as an experimental treatment due to the lack of high-quality clinical research.

Changes in midgut and brain proteins in Morimus funereus larvae depending on nutritive substrate.

The response of Morimus funereus larvae to total starvation and refeeding with qualitatively different nutritive substrates (artificial diets supplemented with yeast as a source of B complex vitamins or with a digestibility reducer-tannic acid) was examined in this paper. Refeeding resulted in a compensatory increase of larval growth. Feeding and refeeding with qualitatively different nutritive substrates affected both quality and quantity of midgut and brain proteins. The observed differences suggest the possible switching of enzyme isoforms in M. funereus midgut and changes in synthesis/secretion of neurohormones, depending on food presence and its nutritional value.

The effect of temperature on midgut and brain protein profiles in Morimus funereus larvae (Coleoptera: Cerambycidae).

The 7-days shift of M. funereus larvae, from nature to a constant temperature of 23 degrees C led to changes in midgut and brain protein quality and quantity. The changes in midgut protein profiles are characterized by an intensified protein band Mr of 29 kD, the absence of protein Mr of 22 kD and less intense bands Mr of 8.5-2.5 kD. Electrophoretic patterns of brain proteins showed less intense Mr of 66-2.5 kD protein bands.
