Mapping the Scientific Structure of Medical and Laboratory Equipment Patents in USPTO database between 1984 and 2014
Maryam Emami, Nosrat Riahinia, Faramarz Soheili,
Volume 12, Issue 6 (Feb & Mar 2019)
Abstract
Background and Aim: The purpose of this study was to analyze the co-occurrence of the terms of medical and laboratory equipment patents in the United States Patent and Trademark Office between 1984 and 2014.
Materials and Methods: This research was an applied study using scientometrics and co-word analyses. The statistical population of the present study included all patents of medical and laboratory equipment registered in the United States Patent and Trademark Office database between 1984 and 2014. As a result, a total of 13424 patents were retrieved.
Results: The results revealed that in terms of frequency, the keyword "Menstrual Fluid" and in terms of co-occurrence, two keywords (Menstrual Fluid and Magnetic Resonance Image Apparatus) were the most frequent ones in medical and laboratory equipment studies. The results of hierarchical clustering with "Ward's method" led to the formation of eight clusters in this area including the following: General Equipment, Rehabilitation Equipment, Dental Equipment, Therapeutic Equipment, Emergency Equipment, Laboratory Equipment, Diagnostic Equipment, and Medical Consumables.
Conclusion: The analysis of the co-occurrence of words revealed the scientific structure of medical and laboratory equipment well. Accordingly, the scientific issues were extracted and the relationship between them was discovered. The maps of co-word analysis showed several changes, sustainability of concepts, and terms related to this field of science.

Scientometric Study of SMA International Research Outputs
Somayeh Ghavidel, Nosrat Riahinia, Samira Daniali,
Volume 13, Issue 6 (Feb & Mar 2020)
Abstract
Background & Aim: studying scientific outputs by using scientific indices is a useful tool for understanding scientific research. The purpose of this study is to visualize the international research outputs of the SMA subject Area.
Materials & Method: This study is an applied one with an analytical approach and using scientometric indices. The population present in this study includes 4217 WOS records all in the SMA area from 1946 until the end of 2018. The MeSH have been used to identify keywords and Ravar PreMap software for words’ homogenization, VOSviewer, HistCite, and Excel used also.
Conclusion: Ninety-one countries involved in scientific production outputs of this subject area, were among the most influential countries in scientific collaboration. The USA has most of its collaborations with other countries. Of the 946 essential journals identified, HUMAN MOLECULAR GENETICS SMA has got the highest number of citations. Articles in SMA Subject Area with the total number of 6097 keywords have got the 1st rank, of which the “Spinal Muscular Atrophy” has got the highest frequency and the core subject among the nine influential countries. The total number of articles in this area is 8505. Worthy of mentioning, Iran with 58% of the total scientific output ranked nine on the list.
Results: The upward trend of SMA scientific research trend indicates the increasing importance of this area in the world. Due to the the international growth of research in this area and the importance of the participation of international research, researchers in our country should pay more attention to scientific cooperation.

Identifying the Health Information Needs of the Elderly in Public Libraries: A Systematic Review
Faezeh Sadat Bahrololoumi Tabatabai, Nosrat Riahinia, Davoud Haseli, Fatemeh Pazouki,
Volume 19, Issue 2 (7-2025)
Abstract
Background and Aim: With the increasing elderly population and their specific needs, access to health information in public libraries has become increasingly important. Public libraries can play a crucial role in providing reliable health information and enhancing health literacy among the elderly. This study aimed to identify the health information needs of the elderly in public libraries based on global experiences.
Materials and Methods: This study was conducted as a systematic review using the Kitchenham and Charters framework. Relevant articles were retrieved from three major citation databases—PubMed, Scopus, and Web of Science—covering the period from 2010 to 2024. Relevant keywords were used for searches, and reference lists and citations of the retrieved documents were examined to ensure comprehensive coverage. Inclusion criteria consisted of research articles related to the health information needs of the elderly in public libraries. Ultimately, 40 English-language articles were selected and analyzed. The extracted data were coded and categorized qualitatively.
Results: The findings indicated that the health information needs of the elderly in public libraries could be classified into four main categories: (1) Information Needs, including access to diverse health information resources, primary health information, public health and prevention information, and self-care and personal empowerment resources; (2) Educational Needs, encompassing information literacy, health information literacy, and educational events; (3) Social and Cultural Needs, including cultural and recreational activities, social and communication needs, social participation, and reducing social exclusion; and (4) Library Services and Facilities, comprising appropriate physical spaces, assistive reading technologies, and mobile and remote library services.
Conclusion: With the growing elderly population, public libraries face a critical responsibility in promoting the health and well-being of this demographic. The findings of this study reveal that the health information needs of the elderly extend beyond mere access to resources; they encompass educational, social-cultural, and library service dimensions. Therefore, it is essential to move beyond traditional information dissemination approaches and adopt a comprehensive, multilayered, and participatory framework—one that positions libraries as active institutions in enhancing public health among the elderly.
