A bibliometric analysis of chronic subdural hematoma since the twenty-first century

Recurrent Pregnancy Loss: A Bibliometric Review

Background

The research combined different bibliometric techniques to analyze systematically recurrent pregnancy loss (RPL) documents from 1970 to 2023.

Methods

Overall, 1287 documents from the Web of Science database associated with recurrent pregnancy loss between 1970 and 2023 were identified for more than 300 journals. The data were analyzed with VOSviewer software.

Results

The trend of paying attention to the topic of RPL can be divided into three periods. The number of publications on RPL increased significantly after 2010. Most of the papers were published in Obstetrics and Gynecology and Reproductive Biology areas. Utilizing co-occurrence and co-citation analysis, our study found that the most influential documents mapped the knowledge structure, and projected future research directions. The co-occurrence analysis showed five clusters even though the co-citation analysis designates four.

Conclusion

RPL has increased in recent years exponentially and some areas were explained carefully, therefore these results could be used as a research agenda for the future direction by a range of interested beneficiaries.

Advances in acupuncture regulation on the autonomic nervous system from 2013 to 2022: A bibliometric analysis via citespace

OBJECTIVE

To understand research advances and frontiers of acupuncture regulation on the autonomic nervous system (ANS) over the past decade through a bibliometric analysis.

METHODS

Publications related to acupuncture regulation on the ANS were retrieved from the Web of Science Core Collection (WoSCC) database. CiteSpace software was used to analyze the datasets and generate knowledge maps.

RESULTS

A total of 445 relevant publications published between 2013 and 2022 were included in this bibliometric analysis. The number of annual publications fluctuated from 2013 to 2016 but increased gradually from 2016 to 2022. China produced the highest number of publications, while the USA established the most extensive cooperation relationships. China Academy of Chinese Medical Science was the most productive institution. Chen Jiande D.Z. was the most prolific author and Rong Peijing holds the most extensive cooperation network. Han Jisheng was the most co-cited author. Relevant research involved mechanism exploration and clinical efficacy research, and "anti-inflammatory effect" was the most active research topic, especially cholinergic anti-inflammatory mechanisms. The most cited references mainly focused on inflammation. Gastrointestinal and cardiovascular disorders were the most active medical conditions studied in this field.

CONCLUSIONS

Research related to acupuncture regulation on the ANS mainly focused on anti-inflammation, and regulating gastrointestinal and cardiovascular function over the past decade. However, the mechanisms of the autonomic effects of acupuncture need further investigation. High-quality clinical studies are required to determine the optimal parameters of acupuncture for clinical application.

Top 100 cited articles in the thromboangiitis obliterans: a bibliometric analysis and visualized study

OBJECTIVE

Thromboangiitis obliterans (TAO) is one of the most common types of peripheral arterial disease (PAD). This study aimed to explore the characteristics of the top 100 most cited articles in the TAO.

METHODS

A bibliometric analysis based on the Web of Science (WOS) database was performed. Literature was retrieved and ranked by the citations. Listed below are the top 100 citations, including original articles, reviews, full-length proceeding papers, and case reports that were included for analysis. The type of literature, research areas, and languages were recorded. The trends of citations including the total citations, an analysis of publication and citation numbers were conducted each year. We analyzed citations from highly cited countries, authors, institutions, and journals. Research hotspots were gathered by a visualized analysis of author keywords.

RESULTS

Most of the highly cited literature was original articles. A rising trend was observed in the number of citations per year. The peaks in the number of highly cited articles appeared in the year 1998 and 2006. The majority of the articles focused on the cardiovascular system and surgery. Journal of Vascular Surgery published most of the highly cited articles. The USA and Japan contributed nearly half the number of highly cited articles. Mayo Clinic and Nagoya University were highly cited institutions. Shionoya S and Olin JW were both the author with the largest number of citations and the most highly cited author in the reference. Articles that were highly cited most often addressed the following topics: "vasculitis", "autoimmune disease", and "critical limb ischemia". Keywords that were mostly used in recent years were "stem cell therapy", "progenitor therapy", and "immunoadsorption". The detection of bursts of author keywords showed the following: "permeability", "differentiation", and "critical limb ischemia" are recent keywords that have burst.

CONCLUSIONS

In this study, the highly cited contributors in the field of TAO research were identified. Most cited articles in the top 100 focused on the cardiovascular system and surgery. Treatment and pathophysiology including stem cell therapy, progenitor therapy, genetics, autoimmunity, and inflammation are the hotspots of TAO.

The Use of Adjuvant Dexamethasone in Chronic Subdural Hematoma After Surgery

OBJECTIVE

The use of oral anticoagulants in elderly patients is a predisposing factor in developing a subdural hematoma (SDH). The surgical option is often the standard approach but can be accompanied by complications. In this study, we hypothesized that dexamethasone administration after surgery would positively affect subdural change and subdural size in the second week.

MATERIALS AND METHODS

Within the scope of this prospective research, 66 individuals who underwent surgical intervention for chronic subdural hematoma (CSH) at the neurosurgery department either as an outpatient or under emergency circumstances have been enrolled in the study. During the examination, the patients were questioned about the traumatic incident, the localization of injury, and the utilization of anticoagulant and antiplatelet medications. The Glasgow Coma Scale (GCS) was administered to all patients to assess neurological deficits. Computed tomography (CT) was utilized to determine the characteristics of the hematoma.

RESULTS

A total of 66 patients, 22 (33.3%) using and 44 (66.6%) not using dexamethasone, were included in the study. Analysis of variance (ANOVA) indicated that a statistical difference was achieved in the second week after the operation (p<0.043). During the examination of subdural dimensions after the operation and in the second postoperative week, a difference was detected between the radiological membrane and subdural dimensions. A statistically significant correlation was found between anticoagulation and the type of hematoma (p<0.025).

CONCLUSION

Regarding the outcomes of this research, we can conclude that dexamethasone was not associated with any adverse events. Additionally, dexamethasone could leverage reoperation prevention for the elderly with various comorbidities.
