Mapping current trends and hotspots in myasthenia gravis from 2003 to 2022: a bibliometric analysis

IntroductionResearch on myasthenia gravis (MG) has undergone rapid development in recent years. This article aimed to elucidate the characteristics of MG publications over the past 20 years and analyze emerging trends using bibliometric methods.MethodsInformation on MG articles was obtained from the Web of Science Core Collection and stored in Excel for quantitative analyses. Bibliometric analyses were performed using CiteSpace and VOSviewer to visualize publications according to countries/regions, institutions, journals, and authors.ResultsA total of 3,610 publications were included in the analysis. The USA had the highest number of publications (NP) and H-index. Among the institutions, the University of Oxford had the highest NP, followed by the University of Toronto and Duke University. Close cooperation was observed among countries and institutions. The most productive author was Renato Mantegazza, followed by Jan J. Verschuuren, and Amelia Evoli. Muscle & Nerve published the most articles on MG, followed by the Journal of Neuroimmunology and Neuromuscular Disorders. The keyword with the highest strength is “neuromuscular transmission,” followed by “safety” and “rituximab.” Co-citation analysis includes 103 publications cited at least 65 times, categorized into four clusters. Additionally, 123 keywords cited more than 40 times were analyzed and divided into five clusters.ConclusionThis bibliometric analysis shows the framework of research over the past 20 years by mapping the scholarly contributions of various countries or regions, institutions, journals, and authors in MG. The analysis also explores future trends and prospective directions, emphasizing individualized treatment based on subtypes, novel immunotherapeutic approaches, and thymectomy

Analysis of Indoor Thermal and Humidity Environment of Radiant Cooling Coupled with Attached Jet System

The radiant cooling combined with attached jet air supply system is a temperature and humidity independent control system. Radiant cooling panels are used to bear the indoor sensible heat load, and the attached jet air supply is used to bear the indoor humidity load. Numerical simulation method is used to study the changes of indoor relative humidity and dehumidification efficiency of radiant cooling panels installed on ceiling and wall, as well as the advantages and disadvantages of all three systems taking into consideration the radiant cooling coupled with wall attached jet air supply with deflectors in terms of comfort. The results show that the attached jet has good adhesion to the cooling panel and will not leads to condensation; the dehumidification efficiency of wall attached jet is relatively poor; at the height of 0.1m, the thermal comfort of wall radiant cooling system is the best; at the height of 0.7m, the wall radiant cooling system with deflector is the best; in the working range of 1.1 ∼ 2.4m, the wall radiant cooling system is better than the ceiling radiant cooling system with or without deflector

Analysis of Indoor Particle Diffusion in Attached Jet Air Supply System

With the change of the installation position of the radiant panel, the indoor air distribution formed by the attached jet air supply will also change, which will affect the diffusion distribution of indoor particulate matter. Through numerical simulation, the influence of indoor air distribution formed by attached jet air supply on the diffusion distribution of aerosol particles released by human body is studied. It is found that within 0 ~ 300s, 97.2% ~ 98.5% of the aerosol particles of human body jet are captured by the wall, and only a small part of fine particles exists in the air in the form of suspended solids. The final particle concentration of wall attached air supply is the lowest, and the effect of roof attached air supply is in the middle. The indoor particle concentration of wall attached air supply with deflector is higher than that of other forms at the same time in 0 ~ 300s
