Mixed Reality versus Mass or Self-directed Training for Adolescents’ Basic Life Support Instruction: A Prospective, Randomized Pilot Study
Full text linkBackground:
There is limited information about adolescents' Basic-Life-Support (BLS) training.
Objectives:
In this study, adolescents' BLS training proficiency and knowledge retention of the Mixed Reality (MR), Mass-Training (MT), and Self-Directed Learning (SDL) methods were prospectively compared, following the training-outcomes levels-model classification.
Methods:
First-year secondary-school students were randomized into the MR, MT, and SDL groups, and after baseline evaluation, at T0, they received congruent BLS theoretical and Cardiopulmonary-Resuscitation (CPR) training. Knowledge, skills retention, and trainees' training-activity self-evaluation were evaluated utilizing ten (knowledge) and five-items (self-evaluation) questionnaires, a BLS-sequence checklist, and chest compressions recording mannequin one and three months after T0. We used the Kruskal-Wallis test for median comparison.
Results:
At all times, the MR group knowledge answers' median (≥6/10) was significantly higher (p<0.05) than groups MT and SDL (≤6/10), with no significant differences between the latter. The MR CPR skills and BLS checklist acquisition and retention were significantly superior (p<0.05) to the other groups; the SDL group showed limited results. Hands position and chest recoil showed excellent outcomes in all groups and at all times. At all times, trainees positively evaluated the BLS-training importance. Pre-training low self-confidence in BLS practice improved over time, yet not significantly, in group MT. The trainees' majority (62%) preferred the MR method.
Conclusion:
In an adolescent cohort, MR methods' BLS/CPR knowledge and skills acquisition and retention were comparable, if not better, than the MT method and superior to the SDL one. Future multicenter randomized and controlled studies with larger sample sizes and more limited instructor-to-participant ratios are warranted to generalize findings
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Nurses’ perspectives on providing analgesia in the Italian prehospital emergency setting: A phenomenological study
No full textBackground: Effective pain management is a fundamental aspect of prehospital emergency care. However, numerous barriers, including inconsistent protocols, limited pharmacological options, and documentation gaps, hinder optimal pain relief. Emergency medical services (EMS) nurses play a crucial role in assessing and managing pain, yet their perspectives on prehospital analgesia remain underexplored. Objective: This study aims to explore the experiences and perceptions of Italian EMS nurses regarding prehospital pain management, identifying key challenges and potential improvements. Methods: A qualitative study was conducted using an interpretative phenomenological approach. Semi-structured interviews were performed with 14 EMS nurses from various Italian regions. Data was analyzed through thematic analysis, identifying recurring themes related to pain assessment, treatment, and documentation. Results: Five main themes emerged: (1) variability in analgesia protocols and pharmacological options, (2) inconsistent pain assessment and documentation, (3) challenges in pain management related to specific patient populations or environmental and logistical factors, (4) nurses' personal experiences shaping their approach to pain management, and (5) interprofessional collaboration challenges. While nurses emphasized the importance of systematic pain evaluation, barriers such as legal restrictions, inconsistent protocols, and limited pharmacological options were frequently reported. Conclusion: Prehospital pain management by EMS nurses in Italy faces significant challenges. Expanding protocol-approved pharmacological options, improving documentation practices, and enhancing training for pain management in vulnerable populations could improve care. A standardized, evidence-based national framework is needed to optimize pain relief and ensure equitable patient outcomes
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Long-term intrathecal morphine influence on major compounds of the endocrine system in elderly population
No full textBackground: The influence of long-term opioid administration on hormonal levels is not well characterized in the literature. We previously showed that intrathecal opioid therapy significantly influences the homeostasis of immune and endocrine systems. Other authors confirmed that exogenous and endogenous opioids induce this effect. They have a cytokine-like behavior and may function as neurotransmitters, neuromodulators or hormones, as concerning their synthesis, storage and release.Aims: To assess the effects of morphine long-term intrathecal administration on serum levels of Gonadal. Thyroidal and Adrenal axis hormones in an elderly population affected by chronic pain; to assess the correlation between hormone levels and morphine dosage. Methods: Patients suffering from chronic non-cancer pain with or without intrathecal drug delivery system were studied and hormonal levels were monitored, using an immunoradiometric assay kit.Results: The long-term administration of intrathecal morphine influenced part of the endocrine system, in particular, there was a reduction of FSH and LH and an increment of GH serum levels; this effect was morphine dose dependent.Conclusion: Long-term intrathecal opioid administration influenced FSH, LH and GH serum levels. Data on this issue are inadequately described in the literature. The finding of endocrine effects of opioid therapy, nonetheless, cannot be ignored, as it may have clinical relevance in both elderly and young population. We believe that during long intrathecal pain treatments with morphine, clinicians should be aware of both immediate and later opioids side effects, and in particular, they should monitor immune and endocrine changes.

koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
