Mesenchymal stem cells (MSCs) have shown significant potential in bone regeneration and regenerative medicine in recent years. With the advancement of tissue engineering, MSCs have been increasingly applied in bone repair and regeneration, and their clinical application potential has grown through interdisciplinary approaches involving biomaterials and genetic engineering. However, there is a lack of systematic reviews summarizing their applications in bone regeneration. To address this gap, we analyzed the latest research on MSCs for bone regeneration published from 2013 to 2023. Using the Web of Science Core Collection, we conducted a literature search in December 2024 and employed bibliometric tools like CiteSpace and VOSviewer for a comprehensive analysis of the key research trends. Our findings focus on the development of cell engineering, highlighting the advantages, limitations, and future prospects of MSC applications in bone regeneration. These insights aim to enhance understanding of MSC-based bone regeneration, inspire new research directions, and facilitate the clinical translation of MSC research.

Objective: Sciatic nerve injuries often lead to severe pain and motor dysfunction, causing serious impact on patients’ quality of life. Acupuncture, as one of the main therapies in traditional Chinese medicine, is gradually gaining attention in the field of nerve injury due to its potential role in pain relief and nerve repair. Bibliometric and scientific knowledge mapping methods were employed to analyze the current research status, hotspots, and development trends of acupuncture for sciatic nerve injury (SNI) over the past decade. Methods: A literature search was conducted on acupuncture for SNI from the China Knowledge (CNKI), Wanfang, Weipu (VIP), and Web of Science (WOS) databases, and CiteSpace V6.R6 software and VOSviewer1.6.20 software were employed to analyze and visualize keywords from the collaborative network, keyword co-occurrence, and keyword timeline, respectively. Keyword emergence was analyzed and visualization maps were drawn. Results: A total of 907 articles were included in the Chinese database, while 78 articles were included in the WOS database. The leading institutions of the literature in Chinese and English were the Liaoning University of Traditional Chinese Medicine and the Institute of Acupuncture and Moxibustion, respectively. Ma Tieming is the most influential person in the field. A keyword analysis of the Chinese and English literature revealed that Huanjiu and Huizhong points are commonly used and that acupuncture is often applied with drug therapy, physical therapy, and rehabilitation training, which can improve the treatment effect comprehensively. Additionally, the therapeutic mechanism of acupuncture mainly promotes nerve regeneration and repair through the modulation of cytokines and related signaling pathways. Electroacupuncture and neuropathic pain are cutting-edge research topics in this field. Based on the keyword emergence, it is predicted that future studies will continue to focus on acupuncture treatment, functional recovery after SNI, and spinal cord injury, which may become the research hotspots in this field. In addition, future studies could further delve into the selection and physiological mechanisms of acupuncture points and validate the effectiveness of this acupuncture and its integrative therapeutic strategies through a wider range of clinical practices. Conclusion: This study uses visualization software VOSviewer and CiteSpace to provide the current status and trends in SNI of acupuncture over the past decade and predicts potential research frontiers and hot directions.

Background: Optic atrophy (OA) is primarily caused by damage to the retinal pathway system, including widespread degeneration of retinal ganglion cells and axons, leading to visual impairment and blindness. Despite its clinical significance and diverse etiological factors, there is currently a lack of comprehensive bibliometric analyses exploring research trends and hotspots within this field. Method: This study retrieved relevant literature on OA published between 2003 and 2023 from the Web of Science Core Collection database. We conducted a bibliometric analysis using tools such as CiteSpace, VOSviewer, and SCImago Graphica to examine annual publication trends, co-occurrence patterns, collaborative networks among countries and institutions, and the evolution of research hotspots of OA. Results: A total of 5,274 publications were included in the bibliometric analysis, comprising 4,561 research articles and 713 review articles. The United States emerged as the leading country in OA research, followed by Germany and China. Over the past two decades, the primary research hotspots focused on “mitochondrial dysfunction,” “hereditary optic neuropathy,” “ocular hypertension” and “diagnostic techniques.” Future research trends are likely to revolve around “molecular mechanisms” and “therapeutic targets.” Conclusion: This bibliometric analysis provides an overview of research developments in OA over the past 20 years, highlighting the emphasis on the pathological basis of OA and advancements in diagnostic and therapeutic approaches. Future studies should continue to explore the molecular basis of mitochondrial dysfunction to identify potential gene therapy targets for treating OA.

Background: Failure mode and effect analysis (FMEA) is a valuable risk analysis tool aimed at predicting the potential failures of a system and preventing them from occurring. Since its initial use, it has also recently been applied to the healthcare setting, which has been made progressively more complex by technological developments and new challenges. Infection prevention and control (IPC) is an area that requires effective strategies. The aim of this study is to review the literature on the employment of FMEA in the healthcare environment, with special consideration for its application in the infectious disease setting. Methods: An extensive search was carried out in two international and public databases, PUBMED and EMBASE; we included all studies regarding the use of FMEA in hospital settings and human patient care processes. Results: A total of 163 studies published over the period from 2003 to 2023 were included for data extraction. These studies were analyzed regarding bibliometric data (publication year and country of origin), the healthcare issues to be addressed, the application fields, and the utilized FMEA methods. Among these, 13 studies were found that took an interest in infectious diseases. Conclusions: FMEA can be effectively used for healthcare risk assessment. Its implementation as a standard tool in healthcare settings, though demanding, may serve as an important tool for preventing the risk of biohazard incidents, epidemics, and environmental contamination, thereby improving safety for both patients and healthcare workers.

Programmed cell death-1 (PD-1) inhibitors and programmed cell death ligand 1 (PD-L1) inhibitors are considered effective alternatives for the primary treatment of recurrent metastatic cancers. However, they can induce various adverse events affecting multiple organ systems, potentially diminishing patients’ quality of life, and even leading to treatment interruptions. Adverse events related to PD-1/PD-L1 inhibitors differ from those associated with CTLA-4 inhibitors and are more commonly observed in the treatment of solid tumors. This study aimed to address the knowledge gap regarding adverse events related to PD-1/PD-L1 inhibitors. A visual bibliometric network was constructed using VOSviewer, CiteSpace, R software, and the Web of Science Core Collection (WoSCC) to quantitatively analyze this research field. Future research directions were also explored. The USA ranked first in publication count and total citations. Over time, publication types transitioned from case reports to clinical trials. Research on for nivolumab was the most prevalent. The spectrum of cancers treated by PD-1/PD-L1 inhibitors expanded beyond melanoma and lung cancer to include renal cell carcinoma, esophageal cancer, and others. Common adverse events included pneumonitis, myasthenia gravis, and vitiligo. There was a significant increase in multi-phase clinical trials and studies related to biomarkers. This study offers valuable insights for potential collaborators and institutions, highlighting trends in the study of adverse events related to PD-1/PD-L1 inhibitors. The management of these adverse events has become more refined and standardized. Biomarker research and multi-phase clinical trials are likely to be key areas of focus in future studies.
