Scope

AIDSLINE (AIDS Information Online), produced by the U.S. National Library of Medicine, is a collection of bibliographic citations focusing on research, clinical aspects, and health policy issues related to AIDS (Acquired Immune Deficiency Syndrome). This database includes articles from over 3,000 journals published worldwide, as well as government reports, letters, technical reports, meeting abstracts and papers, monographs, special publications, theses, books, and audiovisual materials. Information in the AIDSLINE database is derived from the the following sources: MEDLINE, Health Planning and Administration, meeting abstracts from the International Conferences on AIDS, the Symposia on Non-human Primate Models of AIDS, and AIDS-related abstracts from the Annual Meetings of the American Society of Microbiology.

Searching the AIDSLINE fields

The following alphabetical list provides the two letter label, the relevant alias, and at least one example for all searchable AIDSLINE fields:

             gmhc.af.

All Fields (AF) is an alias for all of the fields which occur in
the source documents, including value-added fields such as Subject
Headings.  The only thing excluded from an All Fields search are
fields such as "floating subheading" or "heading word" which are
created by the loading process and do not actually appear in the
record.

or Smith J.

first initial.  If you are unsure of the spelling of the last name
(macdonald or mcdonald), enter one version and then scroll through the
list of names to find the other.

             et.fs.
             di.fs.

Subheadings are qualifiers added to MeSH subject headings to refine
their meaning.  Terms such as "etiology" or "therapy", when combined
with a MeSH heading, give a very precise idea of what an article covers.

The Floating Subheadings (FS) field contains the 2-letter codes,
such as "po" for poisoning.  The fully spelled out subheadings for any
particular MeSH heading can be viewed using the pull-down menu
TOOLS/Subheadings.

They often, but not always, conform to standardized human gene
nomenclature.  Ignore super or sub-scripts in entry of a gene symbol:

narrower terms from the top of a hierarchy.  In order to retrieve a
term and all of its narrower terms, a subject heading must be
"exploded", that is, the subject heading and all narrower terms are
"OR'd" together. OVID pre-explodes highly-posted broader terms with
their narrower terms during loading.  These pre-exploded MeSH Headings
appear in the XM field.

subheading.  This means that all the grouped subheadings can be
retrieved together by searching on the "pre-exploded" version of the
broad subheading.

The 2-letter codes for the pre-exploded subheadings appear in the
Exploded Subheadings (XS) field.

Abstract
OBJECTIVES: Different approaches to prevent mother-to-child transmission of HIV are being evaluated in developing countries. The first trials using a short regimen of zidovudine have been successful in Thailand, Cote d'Ivoire and Burkina Faso. International and local strategies are now being considered. The Ghent International Working Group on Mother-to-Child Transmission of HIV developed public health policy options to integrate these interventions into basic and maternal and child health (MCH) services. METHODS: The following tasks were undertaken: a critical review of randomized trials; an international pooled analysis of late postnatal transmission of HIV through breastfeeding; a review of the cost-effectiveness and cost-benefit of antiretroviral prophylaxis; a feasibility assessment of preventive strategies, including a postal survey on HIV voluntary counselling and testing (VCT) of pregnant women; the identification of requirements and research priorities for prenatal, obstetric and paediatric care. These projects provided the background for a three-day workshop in Ghent, Belgium, in November 1997. Conclusions were further refined, based on 1998 research findings. RESULTS: A summary of relevant evidence and ten public health recommendations are reported. VCT for pregnant women, a short regimen of zidovudine together with alternatives to breastfeeding currently represent the best option to reduce vertical transmission in most developing countries. The primary goal of the integrated package supporting these interventions is to alleviate overall maternal and infant morbidity and mortality. CONCLUSION: Prevention of mother-to-child transmission of HIV should now be considered for integration into basic health and MCH services of selected countries, with the involvement of governments and donor agencies.
