Macular pigment (MP) is comprised of the carotenoids lutein (L), zeaxanthin (Z), and meso-zeaxanthin (MZ), which selectively accumulate at the macula (central retina) of the eye and are neuroprotective. These carotenoids are also present in the brain, and evidence suggests a close correlation between retinal and brain concentrations. We investigated the(More)
BACKGROUND Age-related macular degeneration (AMD) remains the most common cause of visual loss among subjects over 50 years of age in the developed world. The Irish Longitudinal study on Ageing (TILDA) is a population-based study of subjects aged 50 years or older, designed to investigate factors that influence ageing, and has enabled this investigation of(More)
This article discusses the contribution that international comparisons of the health and well-being of older people make. The comparability of the "HRS family" of studies that have been modeled on the U.S. Health and Retirement Study (HRS) is discussed. The Irish Longitudinal Study of Ageing (TILDA) is introduced, and the comparability of TILDA data with(More)
CONTEXT Declarative memory largely depends upon normal functioning temporal lobes (hippocampal complex) and prefrontal cortex. Animal studies suggest abnormal hippocampal function in hypothyroidism. OBJECTIVE The aim of the study was to assess declarative memory in overt and subclinical (SCH) hypothyroid patients before and after l-T(4) (LT4) replacement(More)
General equilibrium models of international fluctuations which assume complete asset markets predict that consumption will be highly correlated across countries, while the data display correlations which are rather low. It is common to characterize this empirical regularity by noting that cross-country consumption correlations tend to be lower than(More)
A review of 34, 201 multigravid deliveries found 47 patients who had severe pre-eclampsia after previous normotensive, non-albuminuric pregnancies. In 13 of these patients the affected pregnancy was apparently by a new father compared with 3 matched controls (P less than 0.01). This evidence supports the idea of a paternal immunogenetic factor in(More)
BACKGROUND Data is lacking on the association of interpersonal stressors and social isolation with mental disorders and the mediating role of loneliness. Thus, we examined this association prospectively using community-based data. METHODS Data on 6105 adults aged ≥50 years from the Irish Longitudinal Study on Ageing (TILDA) was analyzed. Mental health(More)
This paper explores the influence of international risk sharing on aggregate growth for a country that trades with the rest of the world. Learning by doing supports long-run growth as it generates sector-specific increases in productivity proportional to labor’s allocation across sectors. The paper shows that trade permits specialization in production which(More)
