Summary Background We undertook a Grand Challenges in Global Eye Health prioritisation exercise to identify the key issues that must be addressed to improve eye health in the context of an ageing population, to eliminate persistent inequities in health-care access, and to mitigate widespread resource limitations. Methods Drawing on methods used in previous Grand Challenges studies, we used a multi-step recruitment strategy to assemble a diverse panel of individuals from a range of disciplines relevant to global eye health from all regions globally to participate in a three-round, online, Delphi-like, prioritisation process to nominate and rank challenges in global eye health. Through this process, we developed both global and regional priority lists. Findings Between Sept 1 and Dec 12, 2019, 470 individuals complete round 1 of the process, of whom 336 completed all three rounds (round 2 between Feb 26 and March 18, 2020, and round 3 between April 2 and April 25, 2020) 156 (46%) of 336 were women, 180 (54%) were men. The proportion of participants who worked in each region ranged from 104 (31%) in sub-Saharan Africa to 21 (6%) in central Europe, eastern Europe, and in central Asia. Of 85 unique challenges identified after round 1, 16 challenges were prioritised at the global level; six focused on detection and treatment of conditions (cataract, refractive error, glaucoma, diabetic retinopathy, services for children and screening for early detection), two focused on addressing shortages in human resource capacity, five on other health service and policy factors (including strengthening policies, integration, health information systems, and budget allocation), and three on improving access to care and promoting equity. Interpretation This list of Grand Challenges serves as a starting point for immediate action by funders to guide investment in research and innovation in eye health. It challenges researchers, clinicians, and policy makers to build collaborations to address specific challenges.

Free Fatty acid is an end-product of hepatic metabolism of fructose. Most of past studies have demonstrated significant relationship between gestational high fat diet and metabolic and physiology outcomes in offspring. However, there is a scarce of data extended to the effects of high fructose diet-fed dams on juveniles' progeny. Therefore, the present experiment was designed to examine the later effects of maternal high fructose diet intake during pregnancy and lactation on juvenile offspring rats emotional behaviors and memory abilities. We tested whether methyl donors supplemented to that high fructose diet could reverse the adverse effects. We found at two months of age, anxiety-like behavior and depression-like behavior were elevated in off springs of mother fed to high fructose diet and a sex difference effect with males were more affected than females. In addition, behavioral outcomes indicated that the high fructose diet also impaired spatial working and recognition memories in the Y-maze and object recognition test respectively. Blood glucose intolerance increased significantly in juvenile males rats of dams fed with high fructose diet when compared to females. However, a supplementation of the maternal diet with methyl donors attenuated all these changes. Our study suggested a controlled fructose diet supplemented to methyl donors during critical period of brain developing (in utero and pre-weaning stage), otherwise that could induced irreversible detrimental effects on offspring behavior and cognitive health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
