Development of LactaPedia: A lactation glossary for science and medicine

During the last decade, there have been several publications highlighting the need for consistent terminology in breastfeeding research. Standard terms and definitions are essential for the comparison and interpretation of scientific studies that, in turn, support evidence‐based education, consistency of health care, and breastfeeding policy. Inconsistent advice is commonly reported by mothers to contribute to early weaning. A standard language is the fundamental starting point required for the provision of consistent advice. LactaPedia ( www.lactapedia.com ) is a comprehensive lactation glossary of over 500 terms and definitions created during the development of LactaMap ( www.lactamap.com ), an online lactation care support system. This paper describes the development of LactaPedia, a website that is accessible free of charge to anyone with access to the Internet. Multiple methodological frameworks were incorporated in LactaPedia's development in order to meet the needs of a glossary to support both consistent health care and scientific research. The resulting LactaPedia methodology is a six‐stage process that was developed inductively and includes framework to guide vetting and extension of its content using public feedback via discussion forums. The discussion forums support ongoing usability and refinement of the glossary. The development of LactaPedia provides a fundamental first step towards improving breastfeeding outcomes that are currently well below World Health Organisation recommendations globally.     

Sleep Questionnaire Versus Sleep Diary: Which Measure Is Better?

One questionnaire about a typical week's sleep is more convenient than asking individuals to complete daily sleep diaries. Yet, most clinical evaluations and much sleep and insomnia research rely upon self monitoring via daily sleep diaries. These are often problematic to administer and can be reactive. Therefore, we investigated comparability of two measurement modalities (self monitoring and questionnaire) in a sample of 156 community dwelling older adults, both good and poor sleepers. Results indicate significant and high correlations between corresponding scores on a retrospective sleep questionnaire and on 7 days of self monitoring on a daily sleep diary, thereby suggesting that the two measurement modalities are tapping the same domains. There were, however, significant differences between means on several variables, but there was no systematic pattern to the differences. These findings illustrate the need to tailor measurement modality—retrospective or ongoing—to the setting and the purpose of the evaluation.     

Barriers to the expression of sexuality in the older person: the role of the health professional

Sexuality is an important contributing factor to quality of life and sense of well-being. All adults have the right to express their sexuality, regardless of their age. Research indicates, however, that older people frequently experience barriers to the expression of their sexuality. Many of these barriers are influenced by the health professionals and services that care for them. This paper will outline these barriers and identify strategies that the healthcare professional can implement to help improve practice in this area.     

Localization of CGRP Receptor Components, CGRP, and Receptor Binding Sites in Human and Rhesus Cerebellar Cortex

The cerebellum is classically considered to be mainly involved in motor processing, but studies have suggested several other functions, including pain processing. Calcitonin-gene-related peptide (CGRP) is a neuropeptide involved in migraine pathology, where there is elevated release of CGRP during migraine attacks and CGRP receptor antagonists have antimigraine efficacy. In the present study, we examined CGRP and CGRP receptor binding sites and protein expression in primate cerebellar cortex. Additionally, mRNA expression of the CGRP receptor components, calcitonin receptor-like receptor (CLR) and receptor activity modifying protein 1 (RAMP1), was examined. In addition, expression of procalcitonin was studied. We observed high [³H]MK-3207 (CGRP receptor antagonist) binding densities in the molecular layer of rhesus cerebellar cortex; however, due to the limit of resolution of the autoradiographic image the exact cellular localization could not be determined. Similarly, [¹²⁵I]CGRP binding was observed in the molecular layer and Purkinje cell layer of human cerebellum. CLR and RAMP1 mRNA was expressed within the Purkinje cell layer and some expression was found in the molecular layer. Immunofluorescence revealed expression of CGRP, CLR, and RAMP1 in the Purkinje cells and in cells in the molecular layer. Procalcitonin was found in the same localization. Recent research in the biology of cerebellum indicates that it may have a role in nociception. For the first time we have identified CGRP and CGRP receptor binding sites together with CGRP receptor expression through protein and mRNA localization in primate cerebellar cortex. These results point toward a functional role of CGRP in cerebellum. Further efforts are needed to evaluate this.
