Abstract Background The global incidence of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) is increasing, with increasing suicide reports. However, the bibliometric analysis of global research on PMS and PMDD is rare. We aimed to evaluate the global scientific output of research on PMS and PMDD and to explore their research hotspots and frontiers from 1945 to 2018 using a bibliometric analysis methodology.Methods Articles with research on PMS and PMDD between 1945 and 2018 were retrieved from the Web of Science Core Collection (WoSCC). We used the bibliometric method, CiteSpace V and VOSviewer to analyze publication years, journals, countries, institutions, authors, research hotspots, and trends. We plotted the reference co-citation network, and we used keywords to analyze the research hot spots and trends.Results We identified 2,833 publications on PMS and PMDD research from 1945 to 2018, and the annual publication number increased with time, with fluctuations. Psychoneuroendocrinology published the highest number of articles. The United States ranked the highest among the countries with the most publications, and the leading institute was UNIV PENN. Keyword and reference analysis indicated that the menstrual cycle, depression and ovarian hormones were the research hotspots, whereas prevalence, systematic review, anxiety and depression and young women were the research frontiers.Conclusions We depicted overall research on PMS and PMDD by a bibliometric analysis methodology. Prevalence and impact in young women , systematic review evaluations of risk factors, and the association of anxiety and depression with menstrual cycle phases are the latest research frontiers that will pioneer the direction of research in the next few years.

BACKGROUND Smartphones have become an integral part of our lives with their unprecedented popularity and diversification of applications. The continuous upgrading of information technology has also enabled smartphones to display great potential in the field of healthcare. OBJECTIVE This study aimed to clarify the future research direction of mHealth by analyzing its research trends and latest research hotspots. METHODS This study collected mHealth-related literature published between 2000 and 2020 from the Web of Science database. Descriptive statistics of the literature were computed using Excel software. The publication trends of mHealth research were determined by analyzing the annual number of publications in the literature and annual number of publications categorized based on different countries. Finally, this study used the VOSviewer tool to construct visualization network maps of country/region collaborations and author keyword co-occurrences, and overlay visualization maps of the average publication year of author keywords to analyze the hotspots and research trends in mHealth research. RESULTS In this study, 12,593 mHealth-related research articles published between 2000 and 2020 were collected. The results showed an exponential growth trend in the number of annual publications in mHealth literature. The United States remained the leading contributor to the literature in this area (5,294/12,593, 42%), well ahead of other countries/regions. Other countries/regions also showed a clear trend of annual increases in the number of publications in mHealth literature. Regarding cooperation between countries, the four countries with the largest number of publications, the United States, the United Kingdom, Canada, and Australia, were found to cooperate more closely. The rest of the countries/regions showed a clear geographical pattern of cooperation. The keyword co-occurrence analysis of the top 100 authors formed five clusters, namely: development of mHealth medical technology and its application in various diseases, use of mHealth technology to improve basic public health and health policy, mHealth self-health testing and management in daily life, adolescent use of mHealth, and mHealth in mental health. The research trends revealed a gradual shift in mHealth research from health policy and improving public healthcare to the development and social application of mHealth technologies. CONCLUSIONS To the best of our knowledge, the most current bibliometric analysis dates back to 2016. However, the number of mHealth researches published between 2017 and 2020 exceeds the previous total. Therefore, the results of this study shed light on the latest research hotspots and research trends in mHealth research. These findings provide a useful overview of the development of the field; they may also serve as a valuable reference and provide guidance for other researchers in the field.

Spinal stenosis is a common disease affecting the elderly that is present in a various forms. Its high incidence forces researchers to pay more attention and offer countermeasures. We used the Web of Science Core collection and PubMed database to obtain 5,606 scientific studies concerning spinal stenosis, and the number of publications maintained a roughly increasing trend from 108 in 2000 to 512 in 2018, only declining in 2011. Bibliometric analysis was conducted using the online analysis software CiteSpace and Bibliographic Item Co-Occurrence Matrix Builder (BICOMB). The United States maintains academic leadership in this field. The journal SPINE was the most authoritative, with 695 articles and an average of 12.73 citations. The exported major MeSH terms were further biclustered with gCLUTO according to co-word analysis to reveal research hotspots, including etiology, pathogenesis, clinical manifestation, conservative treatment, operative indication, internal implantation, and postoperative complications. After combination, the main topics focused on pathogenesis and surgical treatment. Narrowing causes flavum ligamentum hypertrophy, and posterior longitudinal ligament ossification is widely accepted. Additionally, minimally invasive surgery and internal implantation fixation are more valid in the clinic. Refining pathological classification and optimizing surgical methods and instrument properties will be important future research directions for spinal stenosis.
