Background: Emergency department utilization has increased tremendously over the past years, which is accompanied by an increased necessity for emergency medicine research to support clinical practice. Important sources of evidence are systematic reviews (SRs) and meta-analyses (MAs), but these can only be informative provided their quality is sufficiently high, which can only be assessed if reporting is adequate. The purpose of this study was to assess the quality of reporting of SRs and MAs in emergency medicine using the PRISMA statement. Methods: The top five emergency medicine related journals were selected using the 5-year impact factor of the ISI Web of Knowledge of 2015. All SRs and MAs published in these journals between 2015 and 2016 were extracted and assessed independently by two reviewers on compliance with each item of the PRISMA statement. Results: The included reviews (n = 112) reported a mean of 18 ± 4 items of the PRISMA statement adequately. Reviews mentioning PRISMA adherence did not show better reporting than review without mention of adherence (mean 18.6 (SE 0.4) vs. mean 17.8 (SE 0.5); p = 0.214). Reviews published in journals recommending or requiring adherence to a reporting guideline showed better quality of reporting than journals without such instructions (mean 19.2 (SE 0.4) vs. mean 17.2 (SE 0.5); p = 0.001). Conclusion: There is room for improvement of the quality of reporting of SRs and MAs within the emergency medicine literature. Therefore, authors should use a reporting guideline such as the PRISMA statement. Active journal implementation, by requiring PRISMA endorsement, enhances quality of reporting.

Blended learning environments (BLEs) have become an indispensable part of higher education and an essential part of course delivery. Although teachers need to be active agents in facilitating students’ self-regulation and interaction, little is known to what extent such support is provided. This study investigated the use of self-regulation strategies (SRS) and interactional methods of teachers and students in BLEs. In a cross-sectional design, 171 teachers and 331 students completed a questionnaire on the use of SRS and the application of human and non-human interactional methods. Results showed that, on average, teachers and students pay little attention to SRS and do not or hardly use interactional methods. Results also showed that experienced and inexperienced teachers did not differ in their attention to SRS, although a significant difference was found between teachers with and without online teaching experience. Teachers with more online teaching experience pay more specific attention to metacognitive and management strategies. A positive relationship was also found between the extent to which teachers use both human and non-human interactional methods and the extent to which they pay attention to SRS in the online component of BLEs. Finally, there was a positive relationship between the extent to which students utilize both human and non-human interactional methods and the extent to which they apply SRS. Outcomes of this research provide insight into the design of BLEs and emphasize the importance of teachers' attention to students’ SRS and the use of interactional methods.

The continuous increase of accident and incident reports has indicated the potential of drones to threaten public safety. The published regulatory framework for small drones is not visibly based on a comprehensive hazard analysis. Also, a variety in the constraints imposed by different regulatory frameworks across the globe might impede market growth and render small-drone operations even more complicated since light drones might be easily transferred and operated in various regions with diverse restrictions. In our study we applied the Systems-Theoretic Process Analysis (STPA) method to small-drone operations and we generated a first set of Safety Requirements (SR) for the authority, manufacturer, end-user and automation levels. Under the scope of this paper, we reviewed 56 drone regulations published by different authorities, and performed (1) a gap analysis against the 57 SRs derived by STPA for the authority level, and (2) Intra-Class Correlations in order to examine the extent of their harmonization. The results suggest that the regulations studied satisfy 5.3% to 66.7% of the SRs, and they are moderately similar. The harmonization is even lower when considering the range of values of various SRs addressed by the authorities. The findings from the drones’ case show that regulators might not similarly and completely address hazards introduced by new technology; such a condition might affect safety and impede the distribution and use of products in the international market. A timely and harmonized standardization based on a systematic hazard analysis seems crucial for tackling the challenges stemmed from technological advancements, especially the ones available to the public.

BackgroundTo reduce homelessness, it is important to gain a better understanding of the differences between homeless people who remain in institutions and those who gain and can sustain independent housing. This longitudinal study explores differences in housing transitions and differences in changes in health and self-determination between formerly homeless people still living in institutions 2.5 years later and those now living in independent housing in the Netherlands.MethodsThis study mapped the housing transitions of 263 participants from when they entered the social relief system (SRS) to 2.5 years later when they were in independent housing or institutions. These individuals were compared at the 2.5-year mark in terms of gender, age and retrospectively in terms of duration of homelessness. They were also compared with regard to changes in psychological distress, perceived health, substance use and self-determination.ResultsTwo and a half years after entering the SRS, 81% of participants were independently housed and 19% still lived in institutions. People in institutions had a longer lifetime duration of homelessness, were more often men, and their number of days of alcohol use had decreased significantly more, whereas independently housed people had shown a significant increase in their sense of autonomy and relatedness.ConclusionFormerly homeless people living in independent housing and in institutions show few health-related differences 2.5 years after entering the SRS, but changes in autonomy and relatedness are distinctly more prevalent, after the same period of time, in those who are independently housed.

Evidence-based research (EBR) is the systematic and transparent use of prior research to inform a new study so that it answers questions that matter in a valid, efficient, and accessible manner. This study surveyed experts about existing (e.g., citation analysis) and new methods for monitoring EBR and collected ideas about implementing these methods. We conducted a cross-sectional study via an online survey between November 2022 and March 2023. Participants were experts from the fields of evidence synthesis and research methodology in health research. Open-ended questions were coded by recurring themes; descriptive statistics were used for quantitative questions. Ideas proposed in this study for monitoring the implementation of EBR can be used to refine methods and define responsibility but should be further explored in terms of feasibility and acceptability. Different methods may be needed to determine if the use of EBR is improving over time.

In psychiatric care professionals perceive some patients as 'difficult', especially patients with long-term non-psychotic disorders. For these patients few evidence-based treatments exist. An intervention program, Interpersonal Community Psychiatric Treatment (ICPT), was developed by the authors. It was evaluated with the aim to increase effective behaviours by both patients and community psychiatric nurses (CPNs).

a b s t r a c t: Objective: To study the impact of target volume changes in brain metastases during fractionated stereotactic radiosurgery (fSRS) and identify patients that benefit from MRI guidance. Material and methods: For 15 patients (18 lesions) receiving fSRS only (fSRSonly) and 19 patients (20 lesions) receiving fSRS postoperatively (fSRSpostop), a treatment planning MRI (MR0) and repeated MRI during treatment (MR1) were acquired. The impact of target volume changes on the target coverage was analyzed by evaluating the planned dose distribution (based on MR0) on the planning target volume (PTV) during treatment as defined on MR1. The predictive value of target volume changes before treatment (using the diagnostic MRI (MRD)) was studied to identify patients that experienced the largest changes during treatment. Results: Target volume changes during fSRS did result in large declines of the PTV dose coverage up to 34.8% (median = 3.2%) for fSRSonly patients. For fSRSpostop the variation and declines were smaller (median PTV dose coverage change = 0.5% (4.5% to 1.9%)). Target volumes changes did also impact the minimum dose in the PTV (fSRSonly; 2.7 Gy (16.5 to 2.3 Gy), fSRSpostop; 0.4 Gy (4.2 to 2.5 Gy)). Changes in target volume before treatment (i.e. seen between the MRD and MR0) predicted which patients experienced the largest dose coverage declines during treatment. Conclusion: Target volume changes in brain metastases during fSRS can result in worsening of the target dose coverage. Patients benefiting the most from a repeated MRI during treatment could be identified before treatment.

The evolution of emerging technologies that use Radio Frequency Electromagnetic Field (RF-EMF) has increased the interest of the scientific community and society regarding the possible adverse effects on human health and the environment. This article provides NextGEM’s vision to assure safety for EU citizens when employing existing and future EMF-based telecommunication technologies. This is accomplished by generating relevant knowledge that ascertains appropriate prevention and control/actuation actions regarding RF-EMF exposure in residential, public, and occupational settings. Fulfilling this vision, NextGEM commits to the need for a healthy living and working environment under safe RF-EMF exposure conditions that can be trusted by people and be in line with the regulations and laws developed by public authorities. NextGEM provides a framework for generating health-relevant scientific knowledge and data on new scenarios of exposure to RF-EMF in multiple frequency bands and developing and validating tools for evidence-based risk assessment. Finally, NextGEM’s Innovation and Knowledge Hub (NIKH) will offer a standardized way for European regulatory authorities and the scientific community to store and assess project outcomes and provide access to findable, accessible, interoperable, and reusable (FAIR) data.
