Abstract Background A review of the literature was carried out to study dust and sandstorm (DSS) in terms of its ecosystem processes and relationship to other dryland disasters in Northeast Asia. Drylands are ecosystems that include grasslands, semi-deserts, and deserts, and these types of ecosystems are vulnerable due to their low primary productivity that depends on a small amount of precipitation. Results Drought, dust, desertification, and winter livestock disasters (called dzud) are unique natural disasters that affect the region. These disasters are related in that they share major causes, such as dryness and low vegetation cover that combine with other conditions, wind, cold waves, livestock, and land-surface energy, to dramatically impact the ecosystem. Conclusions The literature review in this study illustrates the macroscopic context of the spatial and temporal patterns of DSS according to geography, climate, and vegetation growth in the drylands of Northeast Asia. The effects of ocean climates and human activities were discussed to infer a possible teleconnection effect of DSS and its relations to desertification and dzud.

AbstractReports of incidental pneumomediastinum in infants secondary to inflicted trauma are limited. A retrospective review of infants with pneumomediastinum and history of inflicted trauma was performed. A comprehensive literature review was performed. Three infants presented with pneumomediastinum associated with inflicted trauma. Mean age was 4.6 weeks. All patients underwent diagnostic studies, as well as a standardized evaluation for nonaccidental trauma. All patients with pneumomediastinum were resolved at follow-up. Review of the literature identified other cases with similar presentations with related oropharyngeal injuries. Spontaneous pneumomediastinum in previously healthy infants may be associated with inflicted injuries. Clinicians should be aware of the possibility of an oropharyngeal perforation related to this presentation.

A review of the literature on the stages of the formation of temporary and permanent occlusion has been performed. This stages play an important role not only for the full development of the maxillofacial apparatus, temporomandibular joint, but also the whole organism. The role of early tooth extraction in the formation of the physiological state of the dentoalveolar system is considered. The conclusion is drawn about the need for a deeper study of this problem in the structure of general dental morbidity.

Pneumoconiosis, or occupational lung disease, is one of the world’s most prevalent work-related diseases. Silicosis, a type of pneumoconiosis, is caused by inhaling respirable crystalline silica (RCS) dust. Although silicosis can be fatal, it is completely preventable. Hundreds of thousands of workers globally are at risk of being exposed to RCS at the workplace from various activities in many industries. Currently, in Australia and internationally, there are a range of methods used for the respiratory surveillance of workers exposed to RCS. These methods include health and exposure questionnaires, spirometry, chest X-rays, and HRCT. However, these methods predominantly do not detect the disease until it has significantly progressed. For this reason, there is a growing body of research investigating early detection methods for silicosis, particularly biomarkers. This literature review summarises the research to date on early detection methods for silicosis and makes recommendations for future work in this area. Findings from this review conclude that there is a critical need for an early detection method for silicosis, however, further laboratory- and field-based research is required.

Objective: Continuous improvement is vital to ensuring quality in sonography education. The aim of this literature review was to compile and summarize the current literature on accreditation, credentialing, and quality improvement initiatives in sonography education. Materials & Methods: Four sonography-specific journals and six health science/academic databases were searched using the terms education, sonography, ultrasound, accreditation, credential, and quality. The search was limited to findings in the English language, from 2000 to 2020. Results: The search uncovered only 19 articles on this topic in sonography education. The vast majority of papers focused on quality improvement initiatives, while just a few concentrated on accreditation or credentialing. Conclusion: Much of the contemporary sonography educational literature focuses on clinical, lab, or didactic quality improvement initiatives. Overall, it is clear that more research is needed in the field of sonography education. This review provides examples of quality initiative research in other allied health fields that can be useful guides for future sonography educational research.

Abstract Slope and lowland sediment systems throughout southern Africa are dominated by the presence of colluvium with interbedded palaeosols and hardground duricrusts. These sediments correspond to phases of land surface instability and stability, respectively, during the late Quaternary. This study examines the stratigraphy and environmental interpretation of slope sediment records from specific sites in southern Africa for the period of marine isotope stages (MIS) 6 to 1 (~191 ka to present), informed by theoretical ideas of the dynamics of slope systems including sediment supply and accommodation space. Based on this analysis, phases of land surface instability and stability for the period MIS 6 to 1 are identified. The spatial and temporal patterns of land surface conditions are not a simple reflection of climate forcing, but rather reflect the workings of slope systems in response to climate in addition to the role of geologic, edaphic and ecological factors that operate within catchment-scale sediment systems. Considering these systems dynamics can yield a better understanding of the usefulness and limitations of slope sediment stratigraphies.

Background/Context This is the first published systematic literature review with an exclusive focus on Title IX scholarship. This article aims to offer a holistic view of the existing knowledge base in this field presented in peer-reviewed scholarly publications. Purpose This review of the literature identifies key trends in this body of research and highlights strengths, as well as gaps and oversights, that future research should address. Research Design This descriptive literature review systematically collected 169 peer-reviewed articles to identify the conceptual boundaries of the field and the current gaps. Data Collection and Analysis Authors applied Booth, Sutton, and Papaioannou's SALSA approach (Search, AppraisaL, Synthesis, and Analysis) to this systematic review to identify and analyze the 169 articles included in the study. We applied an intersectional feminist lens and Queer of Color critique to the analysis of the included articles. Findings/Results Peer-reviewed scholarly publications on Title IX (169) have generally focused on analyses of legal decisions (93) and studies of athletics (75), with little attention to other aspects of the law. Most studies lacked intersectional analyses of how “sex discrimination” has been understood in K–12 and higher education contexts, which leaves experiences of students of color, transgender students, and LGBQ students missing from most of the scholarship in this field. Conclusions/Recommendations This review of the literature is intended to help scholars interested in issues of sex discrimination and gender equity in educational institutions in the United States have a clear overview of scholarship that already exists related to Title IX in order to ask more focused and critical questions about its impacts and implementation. More research is needed to understand the ways in which educational institutions interpret and apply their responsibilities under this law—particularly through the lenses of intersectional feminism and Queer of Color critique. Contemporary issues, including campus sexual assault, and the negative experiences documented about gay, lesbian, bisexual, and transgender students in schools underline the importance of staying current with Title IX, and the current body of literature indicates scant attention to collecting and analyzing data about this law's application in practice and implications for diverse groups of people.
