Anomalies immunitaires chez les enfants exposés au VIH mais non infectés

La thérapie antirétrovirale prévient la transmission mère-enfant du VIH dans plus de 98% des cas lorsqu’administrée pendant la grossesse, le travail et au nouveau-né. L’accessibilité à la thérapie antirétrovirale dans près de 70% des 1,5 millions cas de grossesses VIH+ dans le monde mène à la naissance de plus d’un million d’enfants exposés non infectés chaque année. Le nombre d’enfants exposés non infectés est à la hausse ainsi que les préoccupations concernant leur santé. En effet, plusieurs groupes ont signalé une augmentation de la morbidité et de la mortalité chez les enfants exposés non infectés. L’analyse des données rétrospectives de 705 enfants exposés non infectés de la cohorte mère-enfant du CMIS a révélé qu’à 2 mois d’âge, les enfants nés de mères ayant une charge virale supérieure à 1,000 copies d’ARN / ml avaient une fréquence de lymphocytes B significativement plus élevés par rapport aux enfants exposés non infectés nés de mères ayant une charge virale indétectable. L’objectif de cette étude est de caractériser ces anomalies. Les lymphocytes, provenant du sang de cordon ombilical et de sang veineux obtenu à 6 et 12 mois d’âge, ont été phénotypés par cytométrie en flux à l’aide des marqueurs CD3 / CD10 / CD14 / CD16 / CD19 / CD20 / CD21 / CD27 / IgM pour les lymphocytes B et CD4 / CD8 / CD3 / CCR7 / CD45RA pour les lymphocytes T. De plus, afin d’étudier les capacités fonctionnelles des lymphocytes B CD19+, la réponse antigène-spécifique au vaccin antitétanique a été mesurée par marquage avec des tétramères fluorescents de fragment C du toxoïde tétanique. Nos travaux ont mis en évidence des différences statistiquement significatives entre les enfants exposés non-infectés (ENI) nés de mères avec une charge virale détectable comparativement à ceux nés de mères avec une charge virale indétectable. À la naissance, les enfants ENI nés de mères avec une charge virale détectable avaient significativement moins de lymphocytes B totaux, plus de lymphocytes B mémoires classiques, activés, plasmablastes et lymphocytes T CD8+ mémoires centrales. À 6 mois, ils avaient significativement plus de lymphocytes B naïfs et significativement moins de lymphocytes T CD8+ effecteurs mémoires. À 12 mois d’âge, ils avaient significativement plus de lymphocytes B et T CD8+ totaux; significativement moins de lymphocytes T CD4+ totaux et leurs lymphocytes T affichaient un profil significativement plus activé (plus de cellules mémoires). L’analyse de la réponse antigène-spécifique a révélé une fréquence plus élevé de lymphocytes B mémoires IgM+ suggérant que les enfants nés de mères avec une virémie détectable ont plus de mal à établir une mémoire immunitaire efficace face au vaccin antitétanique. Nos données suggèrent qu’il y a exposition durant le premier trimestre de grossesse à la virémie maternelle et que cette exposition impacte le système immunitaire en développement du fœtus. Les mécanismes sous-jacents causant ces anomalies doivent encore être élucidés et l’épuisement du compartiment T à la naissance et à 6 mois reste à être investigué. Dans un pays industrialisé où l’accès aux soins est facilité, ces anomalies ont des conséquences modérées mais dans des pays à faible et moyen revenu, les conséquences peuvent être beaucoup plus tragiques voir fatales.

Providing health information to the general public: a survey of current practices in academic health sciences libraries*

A questionnaire was mailed to 148 publicly and privately supported academic health sciences libraries affiliated with Association of American Medical Colleges (AAMC)–accredited medical schools in the United States and Canada to determine level of access and services provided to the general public. For purposes of this study, “general public” was defined as nonaffiliated students or health care professionals, attorneys and other nonhealth-related professionals, patients from affiliated or other hospitals or clinics, and general consumers. One hundred five (71%) libraries responded. Results showed 98% of publicly supported libraries and 88% of privately supported libraries provided access to some or all of the general public. Publicly supported libraries saw greater numbers of public patrons, often provided more services, and were more likely to circulate materials from their collections than were privately supported libraries. A significant number of academic health sciences libraries housed a collection of consumer-oriented materials and many provided some level of document delivery service, usually for a fee. Most allowed the public to use some or all library computers. Results of this study indicated that academic health sciences libraries played a significant role in serving the information-seeking public and suggested a need to develop written policies or guidelines covering the services that will be provided to minimize the impact of this service on primary clientele.

Evidence-Based Practice in PubMed: Are Shared Filters Useful to Health Sciences Academic Users?

Objectives In April 2010, the Université de Montréal’s Health Sciences Library has implemented shared filters in its institutional PubMed account. Most of these filters are designed to highlight resources for evidence-based practice, such as Clinical Queries, Systematic Reviews and Evidence-based Synopsis. We now want to measure how those filters are perceived and used by our users. Methods For one month, data was gathered through an online questionnaire proposed to users of Université de Montréal’s PubMed account. A print version was also distributed to participants in information literacy workshops given by the health sciences librarians. Respondents were restricted to users affiliated to Université de Montréal’s faculties of Medicine, Dentistry, Veterinary Sciences, Nursing and Pharmacy. Basic user information such as year/program of study or department affiliation was also collected. The questionnaire allowed users to identify the filters they use, assess the relevance of filters, and also suggest new ones. Results Survey results showed that the shared filters of Université de Montreal’s PubMed account were found useful by the majority of respondents. Filters allowing rapid access to secondary resources ranked among the most relevant (Reviews, Systematic Reviews, Cochrane Database of Systematic Reviews, Practice Guidelines and Clinical Evidence). For Clinical Study Queries, Randomized Controlled Trial (Therapy/Narrow) was considered the most useful. Some new shared filters have been suggested by respondents. Finally, 18% of the respondents indicated that they did not quite understand the relevance of filters. Conclusion Based on the survey results, shared filters considered most useful will be kept, some will be enhanced and others removed so that suggested ones could be added. The fact that some respondents did not understand well the relevance of filters could potentially be addressed through our PubMed workshops, online library guides or by renaming some filters in a more meaningful way.

Access to oral care --- A systematic review of a continuing public health issue among older adults

Oral health is essential for the general well being of the individual and collectively for the health of the population. Oral health can be maintained by routine dental care and visits to dental professionals, but accessing professional dental care may be a continuing difficulty in vulnerable older adult population. Many older adults are not frequent users of dental care, though oral health is crucial to their well-being and overall health. Access to care is the timely use of personal health services to achieve the best possible health outcomes. ^ Objectives: The aims of this review are to (i) to analyze and elucidate the relationship between socio-economic disparities in gender, ethnicity, poverty status, education and the continuing public issue of access to oral care, (ii) to identify the underlying causes through which these factors can affect access to oral care. This review will provide a knowledgeable basis for development of interventions to provide adequate access to oral care in older adults and implementing policies to ensure access to oral care; through highlighting the various socio economic factors that affect access to oral care among older adults. ^ Methods: This paper used a purposeful review of literature on socioeconomic disparities in access to oral care among older adults. The references considered in this review included all the relevant articles, surveys and reports published in English language, since the year 1985 to 2010, in the United States. The articles selected were scrutinized for relevancy to the topic of access to oral care and which included discussions of the effects of gender, ethnicity, poverty status, educational status in accessing oral care. ^ Results: Evidence confirmed the continuing disparity in access to oral care among older adults. The possible links identified were gender inequality, ethnic differences, income levels and educational differences affecting access to oral care. The underlying causes linking these factors with access to oral care were established. ^ Conclusion: The analysis of the literature review findings supported the prevalence of disparities in gender, ethnicity, income and education with its possible links affecting access to oral care. The underlying causes helped to understand the reasons behind this growing issue of inaccessible oral care. Further research is needed to develop policies and target dental public health efforts towards specific problem areas ensuring equitable access to oral services and consequently, improve the health of older adults.^

InGen of creative production in the health sciences: A workbook companion to innovation generation

InGen of Creative Production in the Health Sciences is a compendium of innovative thinking exercises for individuals and groups, derived from an eclectic array of practical guides for professionals in a variety of fields. Segmented into five subcategories across twenty two chapters, the effort seeks to make techniques for increasing innovative problem solving more accessible to a diverse audience of problem solvers. The chapters of Roberta Ness. Innovation Generation (2012, Oxford University Press) provide the themes for each of the chapters in the workbook. It is intended that those who read Ness. Innovation Generation will benefit from practicing the constructs of innovative thinking exemplified in each exercise.^ The methods used to gather data, in this case mostly innovative thinking exercises, included literature reviews of existing innovative thinking tools, classroom materials, and theory-driven exploration of exercises to fill in gaps in extant materials. Specifically, Google.com and Amazon.com searches were conducted using the terms “innovation,” “innovative,” “innovator,” “creative,” “novelty,” “thinking,” together with some variance of “book,” “workbook,” and “exercise.” The results were sorted thematically to show correspondence with the themes in Ness (2012) and compared to suggested best practices of 50 years of scientific research on innovative thinking. Where themes were suggested by Ness (2012) and peer-reviewed research on innovation but unavailable in published innovation thinking workbooks, new exercises were developed. The five type subcategories into which these results were organized are: individual direct, individual indirect, group direct, group indirect and probing question. It is anticipated that the five type subcategories and spectrum of themes will equip problem solvers in a variety of capacities.^
