The evolution of primary hyperparathyroidism publications and global productivity from past to present: A bibliometric analysis during 1980 to 2022.

The aim of this study was to perform a descriptive analysis of scientific articles about primary hyperparathyroidism (PHPT) using bibliometric approaches. By analyzing the links between the various research components (authors, journals, institutions, countries) of the academic outputs, it was aimed to summarize the intellectual structure of PHPT, identify recent research trends, and determine the global productivity. Three thousand nine hundred fifty-four articles on PHPT published between 1980 and 2022 were pulled from the Web of Science database and analyzed using bibliometric approaches. Bibliometric network visualization maps were used to identify trending topics, citation analysis, and international collaborations. Spearman correlation coefficient was used for correlation analysis. The 3 most prolific authors are Bilezikian JP. (n = 87), Silverberg SJ. (n = 72) and Akerstrom G. (n = 57). The top 3 most productive institutions were Columbia University (n = 133), Udice French Research Universities (n = 127) and Uppsala University (n = 98). The top 3 most productive journals were Surgery (n = 216), Journal of Clinical Endocrinology and Metabolism (n = 201) and World Journal of Surgery (n = 148). The top 3 contributing countries to the PHPT literature were United States of America (n = 1062, 26.8%), Italy (346, 8.7%) and United Kingdom (274, 6.9%). The most studied topics from past to present are parathyroidectomy, hypercalcemia, parathyroid hormone/adenoma/glands, calcium/calcimimetics, scintigraphy/sestamibi, bone mineral density, ultrasound, vitamin D, osteoporosis, minimally invasive parathyroidectomy, brown tumor, nephrocalcinosis/nephrolithiasis, multiple endocrine neoplasia type 1, normocalcemia, pregnancy, imaging/preoperative imaging, parathyroid cancer/carcinoma, asymptomatic primary hyperparathyroidism, and cinacalcet. The trending topics in recent years were normocalcemic primary hyperparathyroidism, trabecular bone score, children, CDC73, microwave ablation, radiofrequency ablation, denosumab, cinacalcet, preoperative imaging, imaging, diagnosis, CT, PET, PET/CT, 4D/CT, SPECT/CT, F-18-fluorocholine, quality of life, fractures, and metabolic syndrome. We can say that there will be an increasing research trend on PHPT in the coming years. In addition to the Western countries such as the United States and European countries with large economies, Japan and Turkey were also identified as leading countries in the development of the PHPT literature. This study provides significant information about the intellectual structure and global productivity of PHPT to clinicians and other researchers interested on PHPT.
