Abstract
Background
Vitamin D deficiency (serum 25(OH)D<50nmol/l) is common in Ireland, particularly amongst older adults, hospital inpatients and nursing home residents. Vitamin D deficiency is associated with increased risk of acute viral respiratory infection and community acquired pneumonia, with several molecular mechanisms proposed to explain this association. Vitamin D supplementation has also been shown to reduce the risk of respiratory infection.
Vitamin D and Covid-19
Correction of vitamin D deficiency is thought to suppress CD26, a putative adhesion molecule for Covid-19 host cell invasion. Vitamin D may also attenuate interferon gamma (IFNγ) and interleukin-6 (IL-6) inflammatory responses, both potent predictors of poorer outcome in critically-ill ventilated patients including those with Covid-19.
Vitamin D Requirements
Irish adults require 25-30μg/d of vitamin D3, an intake not achievable by diet alone, to reliably maintain serum 25(OH)D levels >50nmol/l. Supplementation with doses up to 100μg/d has been shown to be safe for adults, and many agencies and expert …

Infant Feeding Practices In China And Ireland - Ireland Chinese Mother, Qianling Zhou, Katherine Younger, John Kearney
Articles
Introduction: Migration to another country may induce changes in infant feeding practices especially where such practices differ considerably between the two countries. This study was undertaken to compare the infant feeding practices between Chinese mothers who gave birth in Ireland (CMI) with immigrant Chinese mothers who gave birth in China (CMC), and to examine the factors that influence these practices. Methods: A cross-sectional self-administrated survey was conducted among a convenience sample of 322 Chinese mothers living in Ireland. Data were obtained from mailed questionnaires. Infant feeding practices between CMC and CMI were compared by Chi-square or independent sample t-test. Binary …
