Ovid MEDLINE® covers the international literature on biomedicine, including the allied health fields and the biological and physical sciences, humanities, and information science as they relate to medicine and health care. Information is indexed from approximately 5,600 journals published world-wide. Records start in the early 1800's and go all the way to our daily updates.
Ovid MEDLINE® is produced by the National Library of Medicine.
Non MEDLINE Status Records
The Ovid MEDLINE® database contains records with the following possible status besides MEDLINE: Publisher, In-Data-Review, In-Process and PubMed-not-MEDLINE records from NLM.
The Publisher records have recently been added to PubMed via electronic submission from a publisher, and are soon to proceed to the next stage, In-Process. This tag is also on citations received before late 2003 if they are from journals not indexed for MEDLINE, or from a journal that was accepted for MEDLINE after the citations' publication date. These citations bibliographic data have not been reviewed.
The In-Data-Review records have been submitted to NLM electronically by the publisher, and the journal title, date of publication and volume/issue (source data) are being checked.
The In-Process records are undergoing a citation level review; i.e., the author names, article title, and pagination are being checked.
The PubMed-not-MEDLINE records have undergone quality review but are not assigned MeSH headings because the cited item is not in scope for MEDLINE either by topic or by date of publication, or is from a non-MEDLINE journal. These records are constantly changing. PubMed-not-MEDLINE records will not be added to the Medline database.
Ovid receives records from NLM on a daily basis, however we are dependent upon NLM's update schedule.

zzt404xd09 tipranavir.rn.
The RN field can contain the following:
- The unique 10-digit Unique Ingredient Identifiers (UNIIs) assigned by the Food and Drug Administration (FDA) Substance Registration System (SRS)
- The 5- to 9-digit Chemical Abstracts Service (CAS) for Registry Numbers
- The number EC derived from Enzyme Nomenclature to designate a particular enzyme
To find UNII number 8R78F6L9VO (Sumatriptan) search for: 8R78F6L9VO Sumatriptan.rn. or: 8R78F6L9VO*.rn.
To find CAS number 54-16-0 (Hydroxyindoleacetic Acid)), search for: 54-16-0 Hydroxyindoleacetic Acid.rn.
To find EC number (EC 1-14-14-1 (Aryl Hydrocarbon Hydroxylases)), search for: ec-1-14-14-1 aryl hydrocarbon hydroxylases.rn.
A zero (0) is a valid value when an actual number cannot be located or is not yet available. E.g. search for: 0 Pulmonary Surfactants.rn
Note: NLM has not added Chemical Abstracts Service (CAS) registry numbers to MeSH since 1998, therefore only registry numbers that were previously available are displayed in the MEDLINE record.

The Secondary Source AN (SA) index contains the unique identifiers of outside resources discussed in MEDLINE articles. The display will include the Secondary Source ID (SI) and the unique identifier separated by a forward slash (GENBANK/S78411). If you wish to search all works from a particular databank use the Secondary Source ID (SI) index: refseq.si.
aim.sb.
The Journal Subset (SB) field identifies the subset for MEDLINE records from certain journal lists or records on specialized topics. Some of these values are found on extremely small numbers of records. Citations may contain more than one occurrence of this field. The value is true at the time the record was created. If the status of a journal changes, the value on the record does not change.
Subset field codes and values are as follows. If you want to see a complete definition of each code please visit. https://www.nlm.nih.gov/bsd/licensee/elements_descriptions.html#citationsubset

summer.se.
The Season (SE) field contains the month or season that the citation article was published.
The field usually consists of a three-character alphabetic abbreviation of the month or season.
hierarchy social.sh.
randomized controlled trial.sh.
The MeSH Subject Headings (SH) field contains the Medical Subject Headings used by indexers at the National Library of Medicine (NLM) to describe the content of an article. NLM's MeSH terms are organized in a hierarchy, or "tree" structure.
MeSH headings are entered into the index as phrases and should be searched as they appear in the NLM MeSH books or in our Tree display.
clinicaltrials.si.
The Secondary Source ID (SI) identifies secondary source databanks with unique identifiers of outside resources discussed in MEDLINE articles. The field is composed of the source acronym: GENBANK.
The Secondary Source ID (SI) formerly known as the Molecular Sequence (MS) field was added to Ovid MEDLINE(R) in 1988.

The Status (ST) field contains the status of the citation.
In-Data-Review records have passed the first step in quality control and will either be reissued as In-process records or go directly to PubMed-not-MEDLINE as the final record status.
In-Process records are electronically submitted and have gone through the second citation-level review.
Medline records have passed all steps in quality control and have been indexed.
Publisher - Citations recently added to PubMed via electronic submission from a publisher, and are soon to proceed to the next stage, PubMed - in process. This tag is also on citations received before late 2003 if they are from journals not indexed for MEDLINE, or from a journal that was accepted for MEDLINE after the citations' publication date. These citations bibliographic data have not been reviewed.
PubMed-not-MEDLINE records have gone through the second citation-level review, but are from non-Medline journals or precede the date a journal was selected for MEDLINE indexing but are now being submitted for inclusion.
recessive.sy.
The Synonyms (SY) field contains a synonymous name for generic drug names that are not actual trade names.
zou.tc.
The Title Comment (TC) field pertains to and contains citations to associated journal publications, e.g., comments, errata, retractions, or cited references. These data enable links between the record at hand and its associated citations.
This field begins with the indication of comment or correction type (see Comments (CM) fields for a full list of types) and then displays the Journal Abbreviation (JA), Date of Publication (DP), Volume (VO), Issue/Part (IP) and Page (PG).
zzf51.ti.
The title sometimes includes notes, in brackets, about the article, such as an indication that it is a letter, editorial, or comment.
heart.tw.
The Text Word (TW) index in Ovid MEDLINE(R) includes Title (TI) and Abstract (AB).
In order to perform a free-text search in all of the relevant fields that contain text words appropriate for a subject search, you are advised to use the multi-purpose field (MP), e.g. heart.mp.
10339538.ui.
9990101.ui.
The Unique Identifier (UI) field contains the PMID (PubMed identifier or PubMed unique identifier) that is the unique number assigned to each PubMed record.
PMIDs do not change over time or during processing and are never reused.
20170127.up.

2016 04 20.vd.
NLM does not expect many journals will publish versions, thus the incidence of versioned citations will be small.
"5".vi.
suppl.vo.

whales.xm.
tu.xs.
pd.xs.
The Exploded Subheadings (XS) field displays the two-letter codes for the pre-exploded subheadings.
Sometimes multiple MeSH Subheadings can be logically grouped together. Such related groups of subheadings are "pre-exploded" under one broad subheading. This means that all the grouped subheadings can be retrieved together by searching on the "pre-exploded" version of the broad subheading. These pre-exploded MeSH Headings are displayed in the MeSH Subject Headings (SH) field. Their complete list can be found in https://www.nlm.nih.gov/mesh/subhierarchy.html. The CAPITAL two letter codes in the left column are the Exploded Subheadings. Terms under the exploded subheading are also searched when you use the exploded subheading.
For example, the Ovid search: an.xs retrieves any records that contain the subheadings, Analysis, Blood, Cerebrospinal Fluid, Isolation and Purification or Urine.
2016.yr.
Advanced Searching
You can use the NOT operator in both unqualified searches and searches applied to a specific field.
ADJ1 Next to each other, in any order
ADJ2 Next to each other, in any order, up to 1 word in between
ADJ3 Next to each other, in any order, up to 2 words in between
ADJ99 Next to each other, in any order, up to 98 words in between
For example, the search physician adj5 relationship retrieves records that contain the words physician and relationship with a maximum of four words in between in either direction. This particular search retrieves records containing such phrases as physician patient relationship, patient physician relationship, or relationship between cancer patient and physician.
Please note Ovid�s order of operation handles terms within parentheses first. Therefore it is recommended to apply the ADJn operator in one-on-one operations to avoid missing out on results. E.g. stroke adj4 (blood pressure or high blood pressure) could potentially miss out on some combinations of stroke with high blood pressure. The optimum way to execute this on Ovid is: (stroke adj4 blood pressure) OR (stroke adj4 high blood pressure).
The frequency operator cannot be applied to multiple fields (e.g. .ti,ab.) or fields that are composed out of other fields such as the Source field (.so.).
"go/no-go"
"Single trial-based prediction of a go/no-go decision in monkey superior colliculus"
"3".vo
"Nature Clinical Practice Cardiovascular Medicine. 3(12):689-92, 2006 Dec."
Quotation marks can be used to retrieve records that contain literal strings, when the string includes special characters, such as a forward slash (/).
Quotation marks can also be used to retrieve records that contain numbers that may otherwise be confused for earlier searches. In the example, a search for 3.vo would limit the string from your third search in your search history to the volume field. By including the number in quotation marks, the search will retrieve documents with a 3 in the volume number.
Stopwords
Therefore a search: at risk for diabetes.ti will also find: at risk of diabetes. The distance of one word in between is kept, but the stopword "for" is ignored.
Limits
Limit
limit 1 to adult
limit 1 to middle aged
A limit to Animals restricts retrieval to documents which are primarily about animal subjects. It will retain articles about both human and animal subjects. Consider also the Limit to Animal Type, which will allow you to select from a list of common experimental research animals.
limit 1 to rabbits
Limiting to Clinical Queries will restrict retrieval clinically sound studies. There are nine categories provided, and the emphasis may be Sensitive (i.e., most relevant articles but probably some less relevant ones), Specific (i.e., mostly relevant articles but probably omitting a few), or Optimized (i.e., the combination of terms that optimizes the trade-off between sensitivity and specificity).
These filters, based on the work of R. Brian Haynes MD, PhD et al. of the Health Information Research Unit (HIRU) at McMaster University, are intended for clinicians. A detailed explanation of the strategies behind these limits can be found at http://hiru.mcmaster.ca/hiru/HIRU_Hedges_MEDLINE_Strategies.aspx.
This is a good way to limit your retrieval to journals more commonly found in hospital and medical library collections.
A limit to Humans restricts retrieval to articles which are about human subjects. If you limit by Age Group you do not need to use this limit.

Special Ovid Filters for MEDLINE
limit 2 to Children - focussed
You can use Special Ovid Filters to restrict retrieval to a pre-defined set of records, populated by a special Ovid search strategy for that topic. As the results sets for these filters are created with every database update, the results display quickly. Ovid filters are �AND� combined with the search line you are trying to limit, unless stated otherwise (e.g. humans only).
Each of the search hedges below are based on publicly available filters that have been reviewed, translated and improved by Ovid expert searchers. While these filters aren�t validated by Ovid, we provide the full transcript for each filter below and we have placed a reference for each filter where applicable. You may want to review the underlying terms and modify them as necessary. Ovid welcomes your suggestions to enhance the filters; to provide feedback and ideas for the Special Ovid Filters, please contact [email protected].

limit 1 to Veterinary Science
limit 1 to toxicology
Limiting to Subject Subsets will restrict retrieval to the specific subject chosen. These Subject Subset limits are based on the Subset limits in PubMed. If you choose this option you will be presented with an alphabetical list of Subject Subsets to choose from.
A limit to Structured Abstracts will restrict retrieval to citations with distinct labelled sections in the abstract (e.g., Introduction, Methods, Results, Discussion) for rapid comprehension.
Ovid MEDLINE also offers limits to Clinical Queries. These limits restrict retrieval to clinically sound studies. There are nine categories provided, and the emphasis may be Sensitive (as in most relevant articles but probably some less relevant ones), Specific (as in mostly relevant articles but probably omitting a few), or Optimized (as in the combination of terms that optimizes the trade-off between sensitivity and specificity). A detailed explanation of the strategies behind these limits can be found at http://hiru.mcmaster.ca/hiru/HIRU_Hedges_MEDLINE_Strategies.aspx.
The Clinical Queries are based on the work of R. Brian Haynes MD, PhD et al. of the Health Information Research Unit (HIRU) at McMaster University, are intended for clinicians.
Sentence syntax for the limits is as follows.
- limit 1 to "Therapy (sensitivity)"
- limit 1 to "Therapy (specificity)"
- limit 1 to "Therapy (optimized)"
A complete list of queries is available from within the Ovid interface.
Tools
The following Search Tools are available for this database. For specific information on using these tools, refer to the Ovid Online Help linked below.
- Tree
Note: Because MEDLINE includes Check Tags as limits, if you search for any of these terms in Advanced Search as an unqualified search, instead of showing the "map to subject heading" display, the search for that check tag will be excuted automatically. However on Ovid the only Check Tags that still exhibit this behaviour are "Male" and "Female". On customer request all other checktags will map to the MeSH Tree just like any other search term.
- Permuted Index
- Scope Notes
- Explode
- Subheadings
Note about Pharmacological Actions and MeSH tree for Ovid MEDLINE:
Unlike PubMed, Ovid MEDLINE only has 1 hierarchical tree. Therefore the Pharmacological Actions are included in the Ovid MEDLINE tree display as "[Drug Terms (Non MeSH)]". Secondly the "explode function" on Ovid automatically includes Pharmacological Actions when applicable.
Example: exp air pollutants/
- Includes all MeSH terms for Air Pollutants: Air Pollutants/, "Air Pollutants, Occupational"/, "Air Pollutants, Radioactive"/, "Greenhouse Gases"/
- Includes all Pharmacologic Actions MeSH terms: Gasoline/, Hydrogen Sulfide/, Particulate Matter/, Radon/, Sulfur Dioxide/, Vehicle Emissions
- Does not include the Supplementary Concept terms for Air Pollutants: 1,6-hexamethylene diisocyanate, 2-nitrofluoranthene, 2-nitrofluorene, bisphenol A, methyl tert-butyl ether, silicon nitride.

The purpose of this review is to summarize existing knowledge about the pathophysiology, diagnosis, and management of fungal sensitization in asthma and highlight unmet needs and target areas for future investigation. RECENT FINDINGS: Fungal sensitization may occur by a normal or aberrant immune response. Allergic sensitization to fungi is mediated by the adaptive immune response driven by TH2 cells and the innate immune response driven by the innate lymphoid cells group 2. Diagnosis of fungal sensitization can be made by either skin prick testing or measurement of fungal-specific serum IgE. Fungal sensitization in asthma has been associated with worse disease severity, including reduced lung function, increased risk of hospitalizations, and life-threatening asthma. A spectrum of disease related to fungal sensitization has been described in asthma including allergic bronchopulmonary mycosis and severe asthma with fungal sensitization (SAFS). The role of antifungals and targeted biologic therapy in asthma with fungal sensitization need further investigation. SUMMARY: There is increasing awareness of the contribution of fungal sensitization to asthma severity. However, there are no therapies with proven efficacy. Randomized clinical trials are needed to further investigate the role of biologics. ISSN Electronic: 1531-6971 ISSN Linking: 1070-5287 Digital Object Identifier: https://dx.doi.org/10.1097/MCP.0...
