Physical inactivity is a major global health concern, contributing to the rising non-communicable disease burden. Elucidating barriers and facilitators influencing participation is critical to promoting activity. This study aimed to synthesize the literature and analyze the extent of research on determinants of physical activity engagement. Scoping review methodology guided the synthesis of 272 publications on factors influencing physical activity. Bibliometric analysis examined publication trends, productivity, influential studies, content themes, and collaboration networks. Results: Since 2010, the United States has led a significant increase in research output. Highly cited articles identified physiological limitations and psychosocial determinants as key barriers and facilitators. Extensive focus was seen in clinical medicine and exercise science journals. Analysis revealed predominant attention to psychosocial factors, physiological responses, and applications in respiratory disease. Gaps remain regarding policy and environmental factors. Conclusion: This review showed major advances in elucidating determinants while revealing the remaining needs to curb the pandemic of inactivity globally. Expanding international collaboration, contemporary theoretical models, and tailored mixed-methods approaches could promote progress through greater global participation. Addressing knowledge gaps across populations and disciplines should be a priority. • Rapid growth in physical activity research, but needs more global diversity. • U.S. dominates this research, wider global perspectives could provide deeper insights. • Past studies focused on physiology and psychosocial factors, but contemporary approaches could strengthen evidence. • Top journals are in exercise/clinical fields, publishing in public health could increase reach. • Research concentrated on psychosocial, physiology, respiratory - more work needed on policy and environment.

Background: Over 800 pesticides are registered for use in the United States. Human studies indicate concern that some pesticides currently in use in large quantities may also pose a carcinogenic hazard. Our objective is to identify candidates for future hazard evaluations among pesticides used in high volumes in the United States and also classified as potential carcinogens by U.S. Environmental Protection Agency (USEPA). We also identify data gaps where further research is needed.Methods: We used a systematic, two-tiered review approach to prioritize pesticides. First, we identified currently registered pesticides classified by USEPA as "possible", "suggestive", or "likely" human carcinogens. Among these, we selected pesticides USEPA has listed as commonly used by volume in at least one sector (agriculture, home and garden, or industry, commercial, and/or government), and those without a published hazard evaluation in the past 5 years. Second, we searched primary literature databases for peer-reviewed human cancer studies reporting pesticide-specific data published since the last USEPA carcinogenicity evaluation for each pesticide, and created evidence maps of the number of studies meeting our criteria for each identified pesticide. No evaluation of study results or risk-of-bias assessments were conducted.Results: We identified 18 pesticides meeting our selection criteria, 16 pesticides had information from human cancer studies published after their initial carcinogenicity review. Of these, eight pesticides had at least three studies for one or more cancer sites: carbaryl, dichloropropene, dimethoate, mancozeb, metolachlor, pendimethalin, permethrin, and trifluralin. A major limitation in the literature revealed a shortage of studies reporting risk estimates for individual pesticides, rather pesticides were grouped by chemical class.Conclusions: Our scoping report provides a map of the existing literature on real-world exposures and human cancer that has accumulated on pesticides classified as potential carcinogens by USEPA and used in high volumes. We also illustrate that several pesticides which are "data-rich" may warrant updated authoritative hazard evaluations. Our two-tiered approach and utilization of evidence mapping can be used to inform future decision-making to update cancer hazard evaluations. [ABSTRACT FROM AUTHOR]

Focusing on environmental review practice in state departments of transportation in the US, the study examines the practices and effects of stakeholder involvement in scoping processes conducted under the National Environmental Policy Act (NEPA). Based on a survey of environmental review staff in 46 of the 50 states, the study finds variation in approaches used by states and relatively high levels of perceived effectiveness. The findings include a number of internal and external factors that contribute to effectiveness and highlight the impacts of participation on the content and outcomes of scoping processes.

Disasters have many deleterious effects and are becoming more frequent. From a health-care perspective, disasters may cause periods of stress for hospitals and health-care systems. Telemedicine is a rapidly growing technology that has been used to improve access to health-care during disasters. Telemedicine applied in disasters is referred to as disaster telemedicine. Our objective was to conduct a scoping literature review on current use of disaster telemedicine to develop recommendations addressing the most common barriers to implementation of a telemedicine system for regional disaster health response in the United States. Publications on telemedicine in disasters were collected from online databases. This included both publications in English and those translated into English. Predesigned inclusion/exclusion criteria and a PRISMA flow diagram were applied. The PRISMA flow diagram was used on the basis that it would help streamline the available literature. Literature that met the criteria was scored by 2 reviewers who rated relevance to commonly identified disaster telemedicine implementation barriers, as well as how disaster telemedicine systems were implemented. We also identified other frequently mentioned themes and briefly summarized recommendations for those topics. Literature scoring resulted in the following topics: telemedicine usage (42 publications), system design and operating models (43 publications), as well as difficulties with credentialing (5 publications), licensure (6 publications), liability (4 publications), reimbursement (5 publications), and technology (24 publications). Recommendations from each category were qualitatively summarized.
