Background: Despite the relevance of mobile technologies and social media (MTSM) for adolescents, their association with depressive disorders in this population remains unclear. While there are previous reviews that have identified the use of MTSM as a risk factor for developing depression, other reviews have indicated their possible preventive effect. Objective: The aim of this review was to synthesize the current evidence on the association between MTSM use and the development or prevention of depressive disorders in adolescents. Methods: An umbrella review was conducted using information published up to June 2019 from PubMed/MEDLINE, PsycINFO, Web of Science, and The Cochrane Library. Systematic reviews focusing on the adolescent population (up to 20 years old) and depression and its potential relationship with MTSM use were included. Screening of titles, abstracts, and full texts was performed. After selecting the reviews and given the heterogeneity of the outcome variables and exposures, a narrative synthesis of the results was carried out. Results: The search retrieved 338 documents, from which 7 systematic reviews (3 meta-analyses) were selected for data extraction. There were 11-70 studies and 5582-46,015 participants included in the 7 reviews. All reviews included quantitative research, and 2 reviews also included qualitative studies. A statistically significant association between social media and developing depressive symptoms was reported in 2 reviews, while 5 reviews reported mixed results. Conclusions: Excessive social comparison and personal involvement when using MTSM could be associated with the development of depressive symptomatology. Nevertheless, MTSM might promote social support and even become a point of assistance for people with depression. Due to the mixed results, prospective research could be valuable for providing stronger evidence.

The effectiveness and safety of shoulder arthroplasties in the general context of a Spanish patient population remains unclear. The aim of this study was to ascertain both the effectiveness and safety of primary shoulder arthroplasties and the prosthesis types used in Spain. A systematic review of all the available literature evaluating the effectiveness and safety of primary shoulder arthroplasties in Spain was performed. A narrative synthesis was performed, and evidence tables were created in four dimensions: study design, arthroplasty characteristics, safety, and effectiveness. Orthopaedic Data Evaluation Panel (ODEP) scores were used to evaluate prosthesis types. Twenty-one studies were selected that included a total of 1293 arthroplasties. The most common indication was fractures, while the prosthesis most frequently used was the Delta Xtend (ODEP 10A). The most common complication was scapular notching. Prosthesis revision rate was approximately 6% for follow-ups between 12 and 79 months. In addition, significant improvements were observed in the Constant–Murley test score after the intervention. Currently in Spain, shoulder arthroplasty can be considered a safe and effective procedure with functional recovery and pain reduction for eligible patients with humeral fracture, rotator cuff arthropathy, fracture sequelae and malunion of the proximal humerus, and degenerative disease. Future longitudinal research and population-based studies could serve to confirm these results and identify points of improvement.

Introduction: The Agency for Health Quality and Assessment of Catalonia (AQuAS) is developing an evaluation tool for mobile health (mHealth) solutions to be used by health technology assessment (HTA) agencies and evaluation experts. In order to have a practical and comprehensive tool taking into account the particularities and challenges of mobile interventions, we considered the views and opinions of key stakeholders. The objective was to present the final selection of general aspects (dimensions) to be assessed in the evaluation, as well as the specific items (criteria) to be included in each of these topics, as a result of different co-design approaches with health professionals, developers, hospital managers, HTA agencies and patients.Methods: A list of criteria used for health apps evaluation were drawn from a literature review. The initial list included eighty-nine criteria items grouped in nine domains. Those criteria and domains were discussed during four focus groups (FG). The importance of the criteria that were not considered as mandatory were later rated through a Delphi online sub-study, in a scale from one to six points, taking as consensus value when median value (median 6, Interquartile range, 0–1) was reached.Results: FG reduced domains and criteria from nine to seven and from eighty-nine to thirty-three, respectively. Most mandatory criteria were related with security, user experience, and clinical effectiveness. Fifty-seven individuals (53.7% of 106 invited to participate) were registered in the online platform (50.1% women, 68.4% 35–64years old and 42.1% from HTA agencies). From fifty non-mandatory criteria under consensus, ten criteria reached consensus (most from solution's content and health problem covered domains) concluding with a 43/7 criteria/domain tool.Conclusions: Insights from main stakeholders on the content of the tool for mHealth assessment were considered through the FG and Delphi technique. The dimensions of security and privacy, clinical effectiveness, solutions’ content, technological aspects, users’ experience and costs were considered mandatory. The dimension related to the impact on the organization was appraised as a secondary domain for evaluation. A workshop with AQuAS research team and HTA external researchers will help to define: the assessment methods (type of instrument, dichotomous responses and/or Likert scales) for the evaluation and the format and dimension's weights of the final design of the tool.

UNSTRUCTURED Understanding how mental health and addictions care is organized and how data are collected is essential for population-based research using administrative records. Catalonia (Spain) has a universal healthcare system and a consolidated mental health and addictions network. This viewpoint provides an overview of service delivery and the real-world data infrastructure supporting health research. We describe the organization of care following a stepped model, including primary care, specialized outpatient and inpatient services, emergency pathways, and support programs. We then map the main population-based registries and digital health platforms, assessing their scope, linkage capabilities, and limitations. Catalonia benefits from universal coverage, integrated policies, and extensive routine data collection across care settings. However, challenges remain, including incomplete interoperability, limited clinical granularity, and unvalidated diagnoses in primary care registries. This viewpoint serves as a reference framework for researchers working with administrative mental health data in Catalonia.
