Publication patterns on neonatal surgery over 65 years

A bibliometric analysis of pediatric liver transplantation publications

Citation counts can identify landmark papers. The aim of this study was to identify and characterize the top-cited articles in the pediatric liver transplantation literature. A search strategy for the Scopus^® database was designed for pediatric liver transplantation publications from 1945 to 2014. The 50 top-cited articles were analyzed. Author co-citation analysis was performed using VOSviewer techniques. There were 2896 articles published between 1969 and 2015. The mean citation count of the top 50 cited articles was 166 (range 95-635). There were three case reports in this top-cited list. There were 15 collaborations in this top-cited list with nine being international. The top-cited publications originated in 12 countries, with the USA and the UK contributing 31 and seven articles, respectively. There were 14 authors with four or more publications in this list. There was a single author with nine publications in the top-cited list. These top-cited papers were found in 16 journals, with three journals collectively publishing over 50% of these publications. Pediatric liver transplantation research is an evolving entity. Surgical techniques and case reports are influential articles. Collaborations at a national and international level produce highly cited articles, which are found in influential journals.

Advanced neonatal medicine in China: a quantitative analysis of research productivity and impact factors

OBJECTIVES

To summarize academic productivity of neonatal medicine in China and explore its relationship with health care workforce and activities.

METHODS

We retrospectively extracted data from national key clinical subspecialty proposals, and used accessible databases as Science Citation Index (SCI), PubMed, and National Natural Science Foundation of China.

RESULTS

Between 2008 and 2010, 61 newborn units at the most advanced level in 31 cities from 28 of 31 provincial districts in mainland China were included. Fifty-two national or international projects and 111 provincial projects were conducted. A total of 171 articles were listed in the SCI database; 23 patents were registered. There were 83 oral presentations in international conferences abroad. One national and 40 provincial government awards were received. Health workforce indexes, such as physicians with MD&PhD degrees, were significantly related to academic productivity. National or international projects (β = .285, p <.001; 95% CI = 0.179, 0.391) and the number of newborn beds (β = .005, p = .016; 95% CI = 0.001, 0.008) were two underlying factors to determine government awards (adjusted R² =  .426). The 10 main cities for neonatal medicine research were also listed.

CONCLUSION

In this study, we established the baseline information on neonatal medicine research in China, which could provide information for further practice.
