Evidence based medicine information, extracted from Medline.
MEVB is a specific collection of evidence based medicine
material compiled using the National Library of Medicine's
search strategy on this subject. The material is extracted
from Medline, so all the usual DataStar features are available,
including the online thesaurus, 'explosions', subheadings and quick
subheadings, and clinical queries.
Documents appear with the same status as those in Medline -
'Medline' or complete, fully indexed documents; 'Publisher',
'In-Process' and 'In-Data-Review' documents -
the latest few weeks of the literature, before they have been
fully indexed for Medline; and 'PubMed-not-Medline' records -
those which are considered to fall out of the scope of Medline's
selection criteria. As in Medline, only fully indexed documents
are included in MEVB Alerts; if you need alerts run against any
type of in-process document, set them up in MEIP.
Use MEVB to answer a wide variety of questions including:
- are there any meta-analyses of measles vaccine administration?
- what is the evidence of estrogen replacement therapy for
osteoporosis?
- are there any reviews of Wernicke encephalopathy after obesity
surgery?

AB - Abstract
There have been few recent studies demonstrating a
definitive association between the transmission of airborne
infections and the ventilation of buildings. The severe
acute respiratory syndrome (SARS) epidemic in 2003 and
current concerns about the risk of an avian influenza (H5N1)
pandemic, have made a review of this area timely. We
searched the major literature databases between 1960 and
2005, and then screened titles and abstracts, and finally
selected 40 original studies based on a set of criteria. We
established a review panel comprising medical and
engineering experts in the fields of microbiology, medicine,
epidemiology, indoor air quality, building ventilation, etc.
Most panel members had experience with research into the
2003 SARS epidemic. The panel systematically assessed 40
original studies through both individual assessment and a 2-
day face-to-face consensus meeting. Ten of 40 studies
reviewed were considered to be conclusive with regard to the
association between building ventilation and the
transmission of airborne infection. There is strong and
sufficient evidence to demonstrate the association between...

All MEVB documents are displayed and searched exactly as in
Medline. Each document has MeSH headings describing the subject
content of the article. The following notes on their use may be
useful.
Descriptors: Medical Subject Main Headings
(MeSH Terms)
The DE paragraph contains descriptors from the Medline Thesaurus,
which consists of about 24,000 controlled Medical Subject
Headings (MeSH). MeSH is available online (..MESH, ..THES, ..TREE,
..EXPL) and in the MVOC database.
Use the MeSH descriptors to produce the most accurate search
results.
The descriptor terms are double-posted. For example, GENES.DE.
will retrieve not only articles indexed to GENES, but also those
on GENES-BACTERIAL, GENES-FUNGAL, GENES-VIRAL etc.
If you wish to restrict your search to the single MeSH term
GENES, qualify to .W.
1_: GENES.DE.
2_: 1.W.
Use the online MeSH to check search terms:
3_: ..MESH GENES
THES GENES$
R1 # GENES
R2 GENES-ABL
R3 2 GENES-APC
R4 2 GENES-ARAC
R5 ART-TRS-GENES -->
R6 # GENES-BACTERIAL
R7 BACTERIAL-STRUCTURAL-GENES -->
GENES-STRUCTURAL-BA+
(...)
then select appropriate R number.
Use hyphens or the ADJ and WITH operators, and qualify to .DE.
when searching multi-word MeSH terms:
4_: GENES-BACTERIAL
5_: GENES ADJ BACTERIAL.DE.
Major emphasis descriptors are displayed with an asterisk (*).
Qualify MeSH terms to .MJ. when you want them to be the major
descriptors, or .MN. for minor descriptors:
6_: GENES-BACTERIAL.MJ.
7_: BREAST-IMPLANTS.MN.
Use the hash mark (#) to explode MeSH terms, i.e. to retrieve all
terms in the hierarchy, for example:
8_: GENES#
Or use the online MeSH and select terms with the hash (#) mark:
9_: ..MESH GENES
THES GENES$
R1 # GENES '65
R2 GENES-ABL '91
R3 2 GENES-APC '93
R4 2 GENES-ARAC '88
R5 ART-TRS-GENES --> GENES-REV '90
R6 # GENES-BACTERIAL '82
(...)
10_: R1#
MeSH Subheadings:
An additional strength of the Medline indexing system is the use
of Subheadings which put the MeSH Main Heading into a more specific
context.
The Subheadings appear in the DE paragraph after the Main
Heading, as a two-letter abbreviation and full word(s):
DE BONE-DENSITY/*DE (drug effects);
CROHN-DISEASE/CO (complications);
DENTAL-CARE-FOR-DISABLED/*;
DENTAL-IMPLANTATION-ENDOSSEOUS/*CT (contraindications);
GLUCOCORTICOIDS/*AE (adverse effects);
HUMAN;
OSTEONECROSIS/CI (chemically induced);
OSTEOPOROSIS/CI (chemically induced);
PERIODONTIUM/DE (drug effects);
SUBSTANCE-DEPENDENCE/CO (complications).
The subheadings must be searched as abbreviations:
11_: GLUCOCORTICOIDS WITH AE
To check which Subheadings are available for the Main Headings,
use the online MeSH and the command ..D SH (..DISPLAY SUBHEADING):
12_: ..MESH GLUCOCORTICOID
THES GLUCOCORTICOID$
R1 GLUCOCORTICOID-ANALOGS -->
R2 2 RECEPTORS-GLUCOCORTICOID
R3 # GLUCOCORTICOIDS
R4 # GLUCOCORTICOIDS-SYNTHETIC
R5 # 4 GLUCOCORTICOIDS-TOPICAL

Pre-exploded Subheadings:
MEDLINE has some pre-exploded subheadings which allow fast
retrieval of some important subheading groups:
QT - Quick therapy. Contains the subheadings TH (therapy), DT
(drug therapy), RT (radiotherapy), DH (diet therapy) and SU
(surgery).
QD - Quick diagnosis. Contains the subheadings DI (diagnosis), RA
(radiology), RI (radionuclide imaging) and US
(ultra-sonography).
QX - Quick toxicology. Contains the subheadings AE (adverse
effects), PO (poisoning), TO (toxicology) and CT
(contra-indications).
14_: INTESTINAL-NEOPLASMS# WITH QT
This gives the same result as, but is faster than:
15_: INTESTINAL-NEOPLASMS# WITH (TH DT SU RT DH)
Some new quick-subheading groups were introduced in 2003. The
full list is as follows:
QA - Quick anatomy (AH BS CY PA UL EM AB IR)
QB - Quick embryology (EM AB)
QC - Quick chemistry (CH AG AA AI CS)
QD - Quick diagnosis (DI PA RA RI US)
QE - Quick etiology (ET CI CO SC CN EM GE IM MI VI PS TM)
QG - Quick surgery (SU TR)
QI - Quick microbiology (MI VI)
QL - Quick complications (CO SC)
QM - Quick metabolism (ME BI BL CF DF EN PK UR)
QN - Quick analysis (AN BL CF IP UR)
QO - Quick organization (OG EC LJ MA ST SD TD UT)
QP - Quick pharmacology (PD AD AE PO TO AG AI CT DU PK)
QS - Quick statistics (SN EP EH MO SD UT)
QT - Quick therapy (TH DH DT NU PC RT RH SU TR)
QU - Quick therapeutic use (TU AD AE CT PO)
QW - Quick epidemiology (EP EH MO)
QX - Quick toxicology (PO TO AE CT)
QY - Quick physiology (PH GE GD IM ME BI BL CF DF EN PK UR PP
SE)
QZ - Quick cytology (CY PA UL)
Quick-Search:
Quick-Search is a fast and easy method of retrieving Subheadings
linked to MeSH terms and pre-exploded Subheadings. The
Subheadings can only be Quick-Searched as abbreviations. Precede
your search with QS:
16_: QS CORONARY-DISEASE# WITH (PP CI DT)
17_: QS ARRHYTHMIA WITH QD
Quick-Search also works very well in combination with the online
MESH and TREE, which saves time and typing:
20_: ..MESH ARRHYTH
THES ARRHYTH$
R1 # ARRHYTHMIA
R2 # ANTI-ARRHYTHMIA-AGENTS
R3 ARRHYTHMIA-SINUS
22_: ..TREE R1
T1 # CARDIOVASCULAR-DISEASES
T2 # HEART-DISEASES
T3 # ARRHYTHMIA
T4 ATRIAL-FIBRILLATION
T5 ATRIAL-FLUTTER
T6 BRADYCARDIA
T7 EXTRASYSTOLE
T8 HEART-BLOCK
T9 ADAMS-STOKES-SYNDROME
(...)
23_: QS (R1 R3 T4 T5) WITH (PP CI DT)
Search statements containing Quick-Search may be saved in Alerts
and for later re-execution.
..RANK and ..MAP are available in the AU, SO, DE and RN
paragraphs.
