Efficacy and safety of hyperbaric oxygen therapy monitored by fluorescein angiography in patients with retinal artery occlusion
CONCLUSION: In RAO patients monitored by FA until spontaneous revascularisation of the central retinal artery, HBOT was effective and safe.PMID:37722767 | DOI:10.1136/bjo-2023-323972

Deep learning detection of diabetic retinopathy in Scotland's diabetic eye screening programme
CONCLUSION: A deep learning-based system for DR grading was evaluated in QA data and images from 11 years in 50% of people attending a national DR screening programme. The system could reduce the manual grading workload at the same sensitivity compared with the current automated grading system.PMID:37704266 | DOI:10.1136/bjo-2023-323395

Vitamin A biomarkers were associated with AGP and CRP over the course of a human norovirus challenge infection
Br J Nutr. 2023 Sep 11:1-19. doi: 10.1017/S0007114523002076. Online ahead of print.ABSTRACTRetinol binding protein (RBP) is used as a proxy for retinol in population-based assessments of vitamin A deficiency (VAD) for cost-effectiveness and feasibility. When the cutoff of <0.7 mol/L for retinol is applied to RBP to define VAD, an equivalence of the two biomarkers is assumed. Evidence suggests that the relationship between retinol and RBP is not 1:1, particularly in populations with a high burden of infection or inflammation. The goal of this analysis was to longitudinally evaluate the retinol:RBP ratio over one month of...

Comparison of test performance of two commonly used multiplex assays to measure micronutrient and inflammatory markers in serum: results from a survey among pregnant women in South Africa
Br J Nutr. 2023 Aug 10:1-22. doi: 10.1017/S0007114523001782. Online ahead of print.ABSTRACTThe combined sandwich-ELISA (s-ELISA; VitMin Lab, Germany) and the Quansys Q-Plex™ Human Micronutrient Array (7-Plex) are multiplex serum assays that are used to assess population micronutrient status in low-income countries. We aimed to compare the agreement of five analytes, α-1-acid glycoprotein (AGP), C-reactive protein (CRP), ferritin, retinol binding protein 4 (RBP4), and soluble transferrin receptor (sTfR) as measured by the 7-Plex and the s-ELISA. Serum samples were collected between March 2016 and December 2017. Pregnant ...

Feasibility and acceptance of artificial intelligence-based diabetic retinopathy screening in Rwanda
CONCLUSION: DR screening using AI led to accurate referrals from diabetes clinics in Rwanda and high rates of participant satisfaction, suggesting AI screening for DR is practical and acceptable.PMID:37541766 | DOI:10.1136/bjo-2022-322683
