Using liminality to understand mothers’ experiences of long-term breastfeeding: ‘Betwixt and between’, and ‘matter out of place’

© 2015, © The Author(s) 2015. Breastmilk is widely considered as the optimum nutrition source for babies and an important factor in both improving public health and reducing health inequalities. Current international/national policy supports long-term breastfeeding. UK breastfeeding initiation rates are high but rapidly decline, and the numbers breastfeeding in the second year and beyond are unknown. This study used the concept of liminality to explore the experiences of a group of women breastfeeding long-term in the United Kingdom, building on Mahon-Daly and Andrews. Over 80 breastfeeding women were included within the study, which used micro-ethnographic methods (participant observation in breastfeeding support groups, face-to-face interviews and online asynchronous interviews via email). Findings about women’s experiences are congruent with the existing literature, although it is mostly dated and from outside the United Kingdom. Liminality was found to be useful in providing insight into women’s experiences of long-term breastfeeding in relation to both time and place. Understanding women’s experience of breastfeeding beyond current usual norms can be used to inform work with breastfeeding mothers and to encourage more women to breastfeed for longer

Non-Steroidal Anti-Inflammatory Drugs and Cognitive Function: Are Prostaglandins at the Heart of Cognitive Impairment in Dementia and Delirium ?

Studies of non-steroidal anti-inflammatory drugs (NSAIDs) in rheumatoid arthritis imply that inflammation is important in the development of Alzheimer’s disease (AD). However, these drugs have not alleviated the symptoms of AD in those who have already developed dementia. This suggests that the primary mediator targeted by these drugs, PGE2, is not actively suppressing memory function in AD. Amyloid-β oligomers appear to be important for the mild cognitive changes seen in AD transgenic mice, yet amyloid immunotherapy has also proven unsuccessful in clinical trials. Collectively, these findings indicate that NSAIDs may target a prodromal process in mice that has already passed in those diagnosed with AD, and that synaptic and neuronal loss are key determinants of cognitive dysfunction in AD. While the role of inflammation has not yet become clear, inflammatory processes definitely have a negative impact on cognitive function during episodes of delirium during dementia. Delirium is an acute and profound impairment of cognitive function frequently occurring in aged and demented patients exposed to systemic inflammatory insults, which is now recognised to contribute to long-term cognitive decline. Recent work in animal models is beginning to shed light on the interactions between systemic inflammation and CNS pathology in these acute exacerbations of dementia. This review will assess the role of prostaglandin synthesis in the memory impairments observed in dementia and delirium and will examine the relative contribution of amyloid, synaptic and neuronal loss. We will also discuss how understanding the role of inflammatory mediators in delirious episodes will have major implications for ameliorating the rate of decline in the demented population
