Summary
Supplementing PubMed with Embase enhances health science literature searches, increasing publication coverage by 6.8% and study coverage by 5.5%. However, coverage benefits vary significantly across specialties and over time.
Area of Science:
- Health Sciences
- Medical Informatics
- Bibliometrics
Background:
- PubMed is a primary resource for health science literature searches.
- PubMed's coverage is uneven across different research specialties.
- Embase is recognized as a valuable supplement to PubMed for health sciences.
Purpose of the Study:
- To analyze the coverage of Embase as a supplement to PubMed.
- To determine if searching Embase can compensate for low retrieval rates in PubMed.
Main Methods:
- Analysis of publications and studies from Cochrane reviews (2012-2016).
- Examination of coverage in Embase for items not indexed in PubMed.
- Two units of analysis: study and publication.
Main Results:
- Supplementing PubMed with Embase increased publication coverage by 6.8% (to 77.7%) and study coverage by 5.5% (to 88.0%).
- Coverage gains varied substantially across different Cochrane review groups and over time.
- Embase indexed 25,119 publications and 9,420 studies not found in PubMed.
Conclusions:
- Embase significantly enhances literature retrieval when used alongside PubMed.
- The benefit of supplementing PubMed with Embase varies, necessitating careful consideration of specific research areas and timeframes.
- Predicting the exact benefit of Embase supplementation requires acknowledging temporal and specialty-specific variations.

01:16Bioequivalence: Overview
1.4K
Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...

16.4K
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...

01:30Methods of Documentation VII: EMR
1.2K
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

01:28Cryo-electron Microscopy
4.0K
Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...

01:09Bioequivalence of Drugs: Drugs with Multiple Indications
69
The concept of therapeutic equivalence (TE) in drugs with multiple indications is complex. A generic drug may be therapeutically equivalent to a brand-name product for one specific indication, but this doesn't necessarily mean it's equivalent for all other indications. Evidence of TE in one patient group and bioequivalence shown in healthy volunteers can support—but not confirm—TE for other indications. However, definitive proof requires individual clinical studies for each...

01:13Bioavailability: Overview
3.7K
Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...
