Background: Clinical research on the rotator cuff tendon is increasing, and new approaches are being applied to rotator cuff disease. Considering the integration of research resources and research trends, it is necessary to conduct an analysis of recent research on the topic. Purpose: To identity the research trends, influential journals, key researchers, and core countries of rotator cuff tendon research between 2000 and 2019. Study Design: Cross-sectional study. Methods: All the literature related to rotator cuff tendon research was retrieved from the Web of Science Core Collection on January 7, 2020. Qualitative and quantitative analyses were processed based on Web of Science and CiteSpace. Results: A total of 4131 studies, which included 3830 articles and 301 reviews, were obtained. There was an upward trend of studies on the topic, with small fluctuations in the past 2 decades. The United States had the most studies, and the number of studies from other countries increased over the study period. Most of the funding sources came from the United States. Articles in the Journal of Shoulder and Elbow Surgery had the most citations for rotator cuff research. Frontier topics, such as arthroscopic repair, mesenchymal stem cell, and “platelet-rich plasma, were identified. The number of citations in 2018 ( r = 0.280; P = .005) and 2019 ( r = 0.307; P = .002) had a weak positive correlation with publication date, indicating that the more recently published articles had a higher number of citations. Conclusion: Valuable information on rotator cuff research based on bibliometric analysis was identified. Arthroscopic repair, mesenchymal stem cell, and platelet-rich plasma might be the research frontiers in this field, and researchers should focus on these topics in future studies.

A ghost is wandering around the web: it is called open access, a proposal to modify the circulation system of scientific information which has landed on the sacred soil of scientific literature. The circulation system of scientific magazines has recently started faltering, not because this instrument is no longer a guarantee of quality, but rather for economic reasons. In countries such as Great Britain, as shown in the following chart, the past twenty years have seen a dramatic increase in subscription fees, exceeding by far the prices of other publishing products and the average inflation rate. The same trend applies to the United States.

Sensing Technology

Phytoplankton blooms have caused many serious public safety incidents and eco-environmental problems worldwide and became a focus issue for research. Accurate and rapid monitoring of phytoplankton blooms is critical for forecasting, treating, and management. With the advantages of large spatial coverage and high temporal resolution, remote sensing has been widely used to monitor phytoplankton blooms. Numerous advances have been made in the remote sensing of phytoplankton blooms, biomass, and phenology over the past several decades. To fully understand the development history, research hotspots, and future trends of remote-sensing technology in the study of phytoplankton blooms, we conducted a comprehensive review to systematically analyze the research trends in the remote sensing of phytoplankton blooms through bibliometrics. Our findings showed that research on the use of remote-sensing technology in this field increased substantially in the past 30 years. “Oceanography,” “Environmental Sciences,” and “Remote Sensing” are the most popular subject categories. Remote Sensing of Environment, Journal of Geophysical Research: Oceans, and International Journal of Remote Sensing were the journals with the most published articles. The results of the analysis of international influence and cooperation showed that the United States had the greatest influence in this field and that the cooperation between China and the United States was the closest. The Chinese Academy of Sciences published the largest number of papers, reaching 542 articles. Keyword and topic analysis results showed that “phytoplankton,” “chlorophyll,” and “ocean” were the most frequently occurring keywords, while “eutrophication management and monitoring,” “climate change,” “lakes,” and “remote-sensing algorithms” were the most popular research topics in recent years. Researchers are now paying increasing attention to the phenological response of phytoplankton under the conditions of climate change and the application of new remote-sensing methods. With the development of new remote-sensing technology and the expansion of phytoplankton research, future research should focus on (1) accurate observation of phytoplankton blooms; (2) the traits of phytoplankton blooms; and (3) the drivers, early warning, and management of phytoplankton blooms. In addition, we discuss the future challenges and opportunities in the use of remote sensing in phytoplankton blooms. Our review will promote a deeper and wider understanding of the field.

Because of the advantages of nanoparticles (NPs) in a variety of industrial, biomedical, and consumer applications, they are intentionally (such as in medicine) or unintentionally (environment exposure) introduced into the human body. However, to date, the detrimental effects of NPs are still unclear, especially in reproductive and developmental toxicity. In this study, we researched 266 articles related to the reproductive and developmental toxicity of NPs from 2006 to December 2016 based on the database of the Web of Science. According to the bibliometric analysis, we found that China and the United States were the leading countries in this field and the major research trends might focus on the pathogenesis of NPs, such as oxidative stress, inflammation, and DNA damage. By this analysis, we provide new insights into the research trends and characteristics of the field.

Mean Cost

Objectives: Despite limited clinical data, many orthopedic practices offer orthobiologic injections. Such injections are not covered by insurance, and thus patients pay out of pocket for these treatments. The purpose of this study was to assess the variability in costs for platelet rich plasma (PRP) and stem cell (SC) injections across practices and evaluate for variables that influence pricing. Methods: A list of 1,345 orthopedic sports medicine practices across the United States was compiled. Calls were made inquiring into the availability of PRP or SC knee injections and associated costs. In addition to pricing, practice type (academic or private), number of providers, and population and income demographics were recorded. Univariate statistical analyses were used to identify differences in availability and cost between variables. Results: Of the contacted offices, 268 (20.2%) offered both treatments, 550 (41.5%) offered only PRP injections, 20 (1.5%) offered only stem cell injections, and 487 (36.2%) did not offer either treatment. The mean (± SD) cost of a PRP injection was $707 ± $388 (range, $175 to $4,973), and the mean cost of a SC injection was $2,728 ± $1,584 (range, $300 to $12,000). Practices offering PRP and SC injections tended to be larger (for PRP - 11.6 physicians per practice vs. 8.1, P<0.001; for SC - 12.3 vs. 9.7, P=0.006). In addition, practices that offered PRP injections were located in areas with higher mean income ($67,500 vs. $64,300, P=0.047). Variables associated with higher cost of PRP injection included city population (P<0.001) and mean income of residents (P<0.001). Conclusion: While the majority of sports medicine practices across the United States offer some type of orthobiologic injection, there exists significant variability in the cost of these injections. The cost for PRP injections is higher in practices located in highly populated areas and in areas with greater mean incomes.

Publication Patterns

The authors in this article first identify the extent to which research articles published in three American Speech-Language-Hearing Association (ASHA) journals included participants, age birth to 18 years, from international backgrounds (i.e., residence outside of the United States), and go on to describe associated publication patterns over the past 12 years. These patterns then provide a context for examining variation in the conceptualization of ethnicity on an international scale. Further, the authors examine terminology and categories used by 11 countries where research participants resided. Each country uses a unique classification system. Thus, it can be expected that descriptions of the ethnic characteristics of international participants involved in research published in ASHA journal articles will widely vary.

Abstract. Background: In recent years, the rate of death by suicide has been increasing disproportionately among females and young adults in the United States. Presumably this trend has been mirrored by the proportion of individuals with suicidal ideation who attempted suicide. Aim: We aimed to investigate whether the proportion of individuals in the United States with suicidal ideation who attempted suicide differed by age and/or sex, and whether this proportion has increased over time. Method: Individual-level data from the National Survey on Drug Use and Health (NSDUH), 2008–2017, were used to estimate the year-, age category-, and sex-specific proportion of individuals with past-year suicidal ideation who attempted suicide. We then determined whether this proportion differed by age category, sex, and across years using random-effects meta-regression. Overall, age category- and sex-specific proportions across survey years were estimated using random-effects meta-analyses. Results: Although the proportion was found to be significantly higher among females and those aged 18–25 years, it had not significantly increased over the past 10 years. Limitations: Data were self-reported and restricted to past-year suicidal ideation and suicide attempts. Conclusion: The increase in the death by suicide rate in the United States over the past 10 years was not mirrored by the proportion of individuals with past-year suicidal ideation who attempted suicide during this period.

Japan and the United States, the world’s largest economies for most of the past half century, have very different immigration policies. Japan is the G7 economy most closed to immigrants, while the United States is the large economy most open to immigrants. Both Japan and the United States are debating how immigrants are and can con-tribute to the competitiveness of their economies in the 21st centuries. The papers in this special issue review the employment of and impacts of immigrants in some of the key sectors of the Japanese and US economies, including agriculture, health care, science and engineering, and construction and manufacturing. For example, in Japanese agriculture migrant trainees are a fixed cost to farmers during the three years they are in Japan, while US farmers who hire mostly unauthorized migrants hire and lay off workers as needed, making labour a variable cost.
