Grand Challenges in global eye health: a global prioritisation process using Delphi method

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 challenge

Studies On The Adaptation Of Bambara Groundnut [Vigna Subterranea (L.) Verdc] In Owerri Southeastern Nigeria

ABSTRACT: Field experiment was conducted on the adaptability of bambara groundnut in humid rain forest tropical zones with six local accesssions in a Randomized Complete Block Design with three replications. Data was collected on the yield and yield attributes, and analysed with analysis of variance (ANOVA) and means separated by least significant difference (LSD p=0.05). Correlation studies were carried out to determine the relationship between yield and yield attributes. Results of analysis of variance showed significant differences in plant height, canopy diameter and petiole length, and no significant differences in number of stem and dry matter weight (biomass) among accessions. Correlation analysis between yield attributes and fresh pod weight indicated positive correlation in all cases. However, plant height and number of stems had a near perfect positive correlation signifying that the higher the height of the plant the greater the yield. The performance ranking of the accessions showed that AC01had the best overall performance while AC-05 had the least
