BACKGROUND
Physical exertion during exercise often leads to increased oxidative stress and inflammatory responses, significantly affecting physical performance. Current strategies to mitigate these effects are limited by their effectiveness and potential side effects. Molecular hydrogen (H₂) has gained attention for its antioxidant and anti-inflammatory properties. Studies have suggested that H supplementation contributes to antioxidant potential and anti-fatigue during exercise, but the variance in the observations and study protocols is presented across those studies.
OBJECTIVE
This systematic review and meta-analysis aimed to comprehensively characterize the effects of H₂ supplementation on physical performance (i.e., endurance, muscular strength, and explosive power), providing knowledge that can inform strategies using H for enhancing physical performance.
METHODS
We conducted a literature search of six databases (PubMed, Web of Science, Medline, Sport-Discus, Embase, and PsycINFO) according to the PRISMA guidelines. The data were extracted from the included studies and converted into the standardized mean difference (SMD). After that, we performed random-effects meta-analyses and used the statistic to evaluate heterogeneity. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to assess the quality of the evidence obtained from this meta-analysis.
RESULTS
In total, 27 publications consisting of 597 participants were included. The search finally included aerobic endurance, anaerobic endurance, muscular strength, lower limb explosive power, rating of perceived exertion (RPE), blood lactate (BLA), and average heart rate (HR) in the effect size (ES) synthesis. The ES of H on aerobic endurance, including V̇O (SMD = 0.09, = 0.394; = 0%) and aerobic endurance exercise (SMD = 0.04, = 0.687; = 0%), were not significant and trivial; the ES of H on 30 s maximal anaerobic endurance (SMD = 0.19, = 0.239; = 0%) was not significant and trivial; the ES of H on muscular strength (SMD = 0.19, = 0.265; = 0%) was not significant and trivial; but the ES of H on lower limb explosive power (SMD = 0.30, = 0.018; = 0%) was significant and small. In addition, H reduces RPE (SMD = -0.37, = 0.009; = 58.0%) and BLA (SMD = -0.37, = 0.001; = 22.0%) during exercise, but not HR (SMD = -0.27, = 0.094; = 0%).
CONCLUSION
These findings suggest that H supplementation is favorable in healthy adults to improve lower limb explosive power, alleviate fatigue, and boost BLA clearance, but may not be effectively improving aerobic and anaerobic endurance and muscular strength. Future studies with more rigorous designs are thus needed to examine and confirm the effects of H on these important functionalities in humans.

INTRODUCTION
This study analyzes the existing academic literature to identify the effects of artificial intelligence (AI) on human resource (HR) activities, highlighting both opportunities and associated challenges, and on the roles of employees, line managers, and HR professionals, collectively referred to as the HR triad.
METHODS
We employed the scoping review method to capture and synthesize relevant academic literature in the AI-human resource management (HRM) field, examining 27 years of research (43 peer-reviewed articles are included).
RESULTS
Based on the results, we propose an integrative framework that outlines the five primary effects of AI on HR activities: task automation, optimized HR data use, augmentation of human capabilities, work context redesign, and transformation of the social and relational aspects of work. We also detail the opportunities and challenges associated with each of these effects and the changes in the roles of the HR triad.
DISCUSSION
This research contributes to the ongoing debate on AI-augmented HRM by discussing the theoretical contributions and managerial implications of our findings, along with avenues for future research. By considering the most recent studies on the topic, this scoping review sheds light on the effects of AI on the roles of the HR triad, enabling these key stakeholders to better prepare for this technological change. The findings can inform future academic research, organizations using or considering the application of AI in HRM, and policymakers. This is particularly timely, given the growing adoption of AI in HRM activities.

Review
Youth exposure to violence increases the risk of poor mental and physical health outcomes lasting into adulthood. Traumatic stress is an outcome of particular concern as the physiological stress response impacts the developing brain. Recently, youth exposure to police violence has been conceptualized as an adverse childhood experience that may impact traumatic stress. To examine this possibility, we conducted a systematic review, drawing upon five databases to gather the existing quantitative and qualitative peer-reviewed research on exposure to police violence and traumatic stress in youth. Searches yielded 27 relevant articles utilizing various study designs: thirteen quantitative, thirteen qualitative, and one mixed method. Twenty-six of the 27 studies found evidence of a relationship between police violence exposure and traumatic stress in youth. Police violence was associated with youth traumatic stress across three types of exposures: direct, vicarious, and anticipated. Studies also explored differential impacts by race and gender. The review revealed current gaps in the literature, such as a lack of data on select sociodemographic groups (e.g., rural youth, LGBTQ+ youth) and potential protective factors (e.g., resilience and school connectedness). In line with the findings, we put forth a research agenda as well as policy and practice recommendations to improve police interactions with youth and mental health services for youth who have been exposed to police violence. Recommendations include improving systematic data collection to track all types of police violence exposure, creating spaces for positive police interactions with youth, and training mental health practitioners to support youth exposed to police violence.

Review
BACKGROUND
Online video sharing platforms like YouTube (Google LLC, San Bruno, CA, USA) have become a substantial source of health information. We sought to conduct a systematic review of studies assessing the overall quality of perioperative anesthesia videos on YouTube.
METHODS
We searched Embase, MEDLINE, and Ovid for articles published from database inception to 1 May 2023. We included primary studies evaluating YouTube videos as a source of information regarding perioperative anesthesia. We excluded studies not published in English and studies assessing acute or chronic pain. Studies were screened and data were extracted in duplicate by two reviewers. We appraised the quality of studies according to the social media framework published in the literature. We used descriptive statistics to report the results using mean, standard deviation, range, and n/total N (%).
RESULTS
Among 8,908 citations, we identified 14 studies that examined 796 videos with 59.7 hr of content and 47.5 million views. Among the 14 studies that evaluated the video content quality, 17 different quality assessment tools were used, only three of which were externally validated (Global Quality Score, modified DISCERN score, and JAMA score). Per global assessment rating of video quality, 11/13 (85%) studies concluded the overall video quality as poor.
CONCLUSIONS
Overall, the educational content quality of YouTube videos evaluated in the literature accessible as an educational resource regarding perioperative anesthesia was poor. While these videos are in demand, their impact on patient and trainee education remains unclear. A standardized methodology for evaluating online videos is merited to improve future reporting. A peer-reviewed approach to online open-access videos is needed to support patient and trainee education in anesthesia.

Review
Literature surrounding miscarriage is broad in scope, yet narrative constructions following miscarriage are significantly under-researched. Few studies have sought to understand sense-making processes following miscarriage, including how and why people story their experience. Consequently, the complexities and nuances of these processes have not been adequately explored. This review aimed to gain insight into what is already known about how people story their experience of miscarriage, as well as research gaps and limitations. A systematic literature review of qualitative literature was conducted across four databases to identify relevant research related to miscarriage narratives and sense-making. Eligibility criteria was applied to a staged screening process to identify the highest quality, peer-reviewed research. Ten studies were included in the review and presented as a narrative synthesis. The literature was divided into five collective themes: women's perspectives, male partner's perspectives, couples' perspectives, healthcare professional's perspectives, and cultural perspectives. The literature review summarises existing knowledge about narrative processes in relation to miscarriage, as well as highlighting research gaps, clinical implications, and directions for future research. When working with those who have experienced involuntary child loss and infertility, there is a need for professionals to have appropriate training to support the provision of compassionate, individualised care and decision-making. The role of language requires consideration as there is a need to address over-medicalised systems of knowledge, and it is important that there is understanding regarding the need for expression, and the various ways that individuals might express their feelings and loss.

Effects of Peer- or Professional-Led Support in Enhancing Adherence to Wearable Monitoring Devices Among Community-Dwelling Older Adults: Systematic Review of Randomized Controlled Trials.
BACKGROUND
Despite the well-documented health benefits associated with wearable monitoring devices (WMDs), adherence among community-dwelling older adults remains low. By providing guidance on the purpose and benefits of using WMDs, facilitating goal-setting aligned with the device's features, promoting comprehension of the health data captured by the device, and assisting in overcoming technological challenges, peers and health care professionals can potentially enhance older adults' adherence to WMDs. However, the effectiveness of such support mechanisms in promoting adherence to WMDs among older adults remains poorly understood.
OBJECTIVE
The aims of this systematic review were to examine the effects of peer- or professional-led intervention programs designed to improve adherence to WMDs among community-dwelling older adults and to identify the intervention components that may positively influence the effects of the intervention.
METHODS
We conducted a comprehensive search across 7 electronic databases (Cochrane Central Register of Controlled Trials [CENTRAL], PubMed, EMBASE, PsycINFO, British Nursing Index, Web of Science, and CINAHL) to identify articles published between January 1, 2010, and June 26, 2023. We specifically targeted randomized controlled trials that examined the impact of peer- or professional-led interventions on enhancing adherence to WMDs among individuals aged 60 years and older residing in the community. Two independent reviewers extracted data from the included studies and assessed the potential risk of bias in accordance with the Cochrane Risk of Bias tool for randomized trials, version 2.
RESULTS
A total of 10,511 studies were identified through the database search. Eventually, we included 3 randomized controlled trials involving 154 community-dwelling older adults. The participants had a mean age of 65 years. Our review revealed that increasing awareness of being monitored and implementing the SystemCHANGE approach, a habit change tool focusing on personal goals and feedback, were effective strategies for enhancing adherence to WMDs among older adults. All of the included studies exhibited a low risk of bias.
CONCLUSIONS
By collaboratively designing specific goals related to WMDs with health care professionals, including nurses and physicians, older adults exhibited a higher likelihood of adhering to the prescribed use of WMDs. These goal-setting tools provided a framework for structure and motivation, facilitating the seamless integration of WMDs into their daily routines. Researchers should prioritize interventions that target awareness and goal-setting as effective approaches to enhance adherence to WMDs among older adults, thereby maximizing the realization of associated health benefits.

IMPORTANCE
Patient education materials (PEMs) can promote patient engagement, satisfaction, and treatment adherence. The American Medical Association recommends that PEMs be developed for a sixth-grade or lower reading level. Health literacy (HL) refers to an individual's ability to seek, understand, and use health information to make appropriate decisions regarding their health. Patients with suboptimal HL may not be able to understand or act on health information and are at risk for adverse health outcomes.
OBJECTIVE
To assess the readability of PEMs on head and neck cancer (HNC) and to evaluate HL among patients with HNC.
EVIDENCE REVIEW
A systematic review of the literature was performed by searching Cochrane, PubMed, and Scopus for peer-reviewed studies published from 1995 to 2024 using the keywords head and neck cancer, readability, health literacy, and related synonyms. Full-text studies in English that evaluated readability and/or HL measures were included. Readability assessments included the Flesch-Kincaid Grade Level (FKGL grade, 0-20, with higher grades indicating greater reading difficulty) and Flesch Reading Ease (FRE score, 1-100, with higher scores indicating easier readability), among others. Reviews, conference materials, opinion letters, and guidelines were excluded. Study quality was assessed using the Appraisal Tool for Cross-Sectional Studies.
FINDINGS
Of the 3235 studies identified, 17 studies assessing the readability of 1124 HNC PEMs produced by professional societies, hospitals, and others were included. The mean FKGL grade ranged from 8.8 to 14.8; none of the studies reported a mean FKGL of grade 6 or lower. Eight studies assessed HL and found inadequate HL prevalence ranging from 11.9% to 47.0%.
CONCLUSIONS AND RELEVANCE
These findings indicate that more than one-third of patients with HNC demonstrate inadequate HL, yet none of the PEMs assessed were developed for a sixth grade or lower reading level, as recommended by the American Medical Association. This incongruence highlights the need to address the readability of HNC PEMs to improve patient understanding of the disease and to mitigate potential barriers to shared decision-making for patients with HNC. It is crucial to acknowledge the responsibility of health care professionals to produce and promote more effective PEMs to dismantle the potentially preventable literacy barriers.

Robots present an opportunity to enhance healthcare delivery. Rather than targeting complete automation and nurse replacement, collaborative robots, or "cobots", might be designed to allow nurses to focus on high-value caregiving. While many institutions are now investing in these platforms, there is little publicly available data on how cobots are being developed, implemented, and evaluated to determine if and how they support nursing practice in the real world. This systematic review investigates the current state of cobotic technologies designed to assist nurses in hospital settings, their intended applications, and impacts on nurses and patient care. A comprehensive database search identified 28 relevant peer-reviewed articles published since 2018 which involve real studies with robotic platforms in simulated or actual clinical contexts. Few cobots were explicitly designed to reduce nursing workload through administrative or logistical assistance. Most included studies were designed as patient-centered rather than nurse-centered, but included assistance for tasks like medication delivery, vital monitoring, and social interaction. Most applications emerged from India, with limited evidence from the United States despite commercial availability of nurse-assistive cobots. Robots ranged from proof-of-concept to commercially deployed systems. This review highlights the need for further published studies on cobotic development and evaluation. A larger body of evidence is needed to recognize current limitations and pragmatic opportunities to assist nurses and patients using state-of-the-art robotics. Human-centered design can assist in discovering the right opportunities for cobotic assistance. Committed research-practice partnerships and human-centered design are needed to guide the technical development of nurse-centered cobotic solutions.

Meta-Analysis
BACKGROUND
Psychotic disorders have long been considered neurodevelopmental disorders where excessive synaptic pruning and cortical volume loss are central to disease pathology. We conducted a systematic review of the literature to identify neuroimaging studies specifically examining synaptic density across the psychosis spectrum.
METHODS
PRISMA guidelines on reporting were followed. We systematically searched MEDLINE, Embase, APA PsycINFO, Web of Science and The Cochrane Library from inception to December 8, 2023, and included all original peer-reviewed articles or completed clinical neuroimaging studies of any modality measuring synaptic density in participants with a diagnosis of psychosis spectrum disorder as well as individuals with psychosis-risk states. The NIH quality assessment tool for observational cohort and cross-sectional studies was used for the risk of bias assessment.
RESULTS
Five studies (k = 5) met inclusion criteria, comprising n = 128 adults (psychotic disorder; n = 61 and healthy volunteers; n = 67 and specifically measuring synaptic density via positron emission tomography (PET) imaging of the synaptic vesicle glycoprotein 2 A (SV2A). Three studies were included in our primary meta-analysis sharing the same outcome measure of SV2A binding, volume of distribution (V). Regional SV2A V was reduced in psychotic disorder participants in comparison to healthy volunteers, including the occipital lobe (Mean Difference (MD)= -2.17; 95% CI: -3.36 to -0.98; P < 0.001 ), temporal lobe (MD: -2.03; 95% CI: -3.19 to -0.88; P < 0.001 ), parietal lobe (MD:-1.61; 95% CI: -2.85 to -0.37; P = 0.01), anterior cingulate cortex (MD= -1.47; 95% CI: -2.45 to -0.49; P = 0.003), frontal cortex (MD: -1.16; 95% CI: -2.18 to -0.15; P = 0.02), amygdala (MD: -1.36; 95% CI: -2.20 to -0.52, p = 0.002), thalamus (MD:-1.46; 95% CI:-2.46 to -0.46, p = 0.004) and hippocampus (MD= -0.96; 95% CI: -1.59 to -0.33; P = 0.003).
CONCLUSIONS
Preliminary studies provide in vivo evidence for reduced synaptic density in psychotic disorders. However, replication of findings in larger samples is required prior to definitive conclusions being drawn.
