Purpose The association between autoimmune diseases and keratoconus (KC) has been proposed based on previous retrospective studies and case reports. The aim of our study is to investigate whether KC is associated with autoimmune thyroid disease. Methods. A comparative study was conducted on 131 adult subjects from September 2015 to May 2017 at Jordan University Hospital, Amman, Jordan. Subjects were classified into 2 groups: subjects with autoimmune thyroid disease, including Graves' disease and Hashimoto's thyroiditis (n = 68), and a healthy group for comparison (n = 63). Subjects with any other conditions known to be associated with KC were excluded. The diagnosis of KC was based on clinical and corneal topographic findings utilizing the Oculus-Pentacam machine. In addition, TSH and total T4 levels as well as thyroid peroxidase antibodies were measured in all study participants. Antithyroglobulin antibodies, thyroid stimulating immunoglobulin, thyroid ultrasound, and thyroid uptake and scan were also selectively performed in some participants. Results This study included a total of 131 participants (101 females and 30 males), including patients and controls. In the multivariate analysis, autoimmune disease was not significantly associated with keratoconus (OR = 1.1; 95% confidence interval: 0.3, 3.8; p value = 0.353) after adjusting for age and gender. Conclusion This study did not show a statistically significant association between autoimmune thyroid disease and KC.

Background:: The recent report of The World Health Organization on diabetes has stressed on the burden of diabetes on low/middle income countries. Recent studies advocated the importance of funding more research on diabetes and insulin in these countries. Recently, the European Research Council advocated the importance of gold Open Access (OA) publishing, where the funded research should be immediately accessible. In this study, we aim to assess funding for insulin research, where we will compare the OA status between funded and unfunded research. Methods:: We used Scopus database to assess insulin research published from January 1st, 1999 to December 31st, 2018. Our bibliometric analysis consisted of three main sections: analysis of all publications on insulin, analysis of funded insulin publications, and analysis of unfunded insulin publications. Results:: We found a total of 388,202 publications, of which only 83,180 (21.4%) were funded. USA produced around 30.1% of the total publications, and the National Institute of Health (NIH) was the major funder with 18.6% of all publications. Of the funded publications, 29,143 (35%) were OA publications, compared to 97,347 (31.9%) of the unfunded publications. We didn’t find a significant difference in OA status between funded and unfunded research. Conclusion:: In concordance with the European Research Council’s decision to support gold OA publishing model, we found that only 35% of the funded and 31.9% of the unfunded insulin research were OA. Although the funded research is increasing in China, most of it is produced in high income countries. This highlights the importance of allocating more funds to low/middle income countries.
