Thirty-one observers (five radiologists, five radiology residents, and 21 nonradiologists) examined low-contrast images of 13 polyvinylchloride cylinders. Image density ranged from 1.91 to 2.05 OD units with a background density of 2.09 OD units. The experiment tested visual performance under various clinically relevant lighting conditions by asking the(More)
INTRODUCTION Retinal nerve fiber layer (RNFL) thinning, assessed by optical coherence tomography (OCT), has recently been reported in various dementias. METHODS We conducted a systematic review and meta-analysis to investigate the diagnostic utility of RNFL thickness measurement using OCT in dementia (including Alzheimer's disease [AD] and mild cognitive(More)
PURPOSE To assess the suitability of retinal images held in the UK Biobank--the largest retinal data repository in a prospective population-based cohort--for computer assisted vascular morphometry, generating measures that are commonly investigated as candidate biomarkers of systemic disease. METHODS Non-mydriatic fundus images from both eyes of 2,690(More)
This study investigates whether individualized, anticipatory temperament guidance could benefit the parent-child relationship and improve children's mental health over time. Parents of preschoolers in a health management organization completed a temperament questionnaire, received written parenting information tailored to their child's temperament, and were(More)
INTRODUCTION The ease of imaging the retinal vasculature, and the evolving evidence suggesting this microvascular bed might reflect the cerebral microvasculature, presents an opportunity to investigate cerebrovascular disease and the contribution of microvascular disease to dementia with fundus camera imaging. METHODS A systematic review and meta-analysis(More)
BACKGROUND. Chronic kidney disease (CKD) is strongly associated with cardiovascular disease and there is an established association between vasculopathy affecting the kidney and eye. Optical coherence tomography (OCT) is a novel, rapid method for high-definition imaging of the retina and choroid. Its use in patients at high cardiovascular disease risk(More)

IASI data has been extensively assimilated in Numerical Weather Prediction (NWP) systems, with significant positive forecast impact. NWP systems have also been used to monitor and further investigate the data, contributing to a detailed characterisation of the performance of the instrument. Here we present a specific analysis that points to a very small(More)
