EMBASE: Excerpta Medica
EMBASE Drugs and Pharmacology
EMBASE Psychiatry


The EMBASE family consists of three separate databases: (1) EMBASE: Excerpta Medica Database, and its subsets, (2) EMBASE Drugs and Pharmacology, and (3) EMBASE Psychiatry.


EMBASE: Excerpta Medica

Scope

EMBASE, the Excerpta Medica database, produced by Elsevier Science, is a major biomedical and pharmaceutical database indexing over 3,500 international journals in the following fields: drug research, pharmacology, pharmaceutics, toxicology, clinical and experimental human medicine, health policy and management, public health, occupational health, environmental health, drug dependence and abuse, psychiatry, forensic medicine, and biomedical engineering/instrumentation. There is selective coverage for nursing, dentistry, veterinary medicine, psychology, and alternative medicine. EMBASE is one of the most widely used biomedical and pharmaceutical databases because of its currency and in-depth indexing. Frequent updates allow access to the latest medical and pharmacological trends. Approximately 375,000 records are added yearly.

EMBASE Psychiatry

Scope

EMBASE Psychiatry is a bibliographic database with abstracts, covering all aspects of psychology, psychiatry, and addiction disorders, including disorder and patient characteristics, diagnoses, and treatments. Examples of covered topics include hospitalization, sexual behavior, suicide, mental deficiency, insurance, treatment efficacy, drug therapy, behavioral interventions, psychotherapy, patient compliance, and drug abuse. This database consists of 10-year rolling coverage, updated quarterly. Over 25,000 new records are added per year. Approximately 3,500 biomedical journals from 70 countries are screened for relevent information. In addition, all records from the top psychiatry journals are selected. EMBASE Psychiatry includes many important journals from Europe and Asia which are not found in other biomedical databases. Normal psychology, experimental psychology, and neurophysiology of mental processes are not included unless there is some relevance to a psychiatric disorder. The print counterpart of this database is the Excerpta Medica Abstract Journal on Psychiatry.

pre-1991 searching of these concepts.

EMTAGS are searched by their numerical code, as listed in the back of
the printed EMTREE Thesaurus, Vol 1.  The codes can be searched with or

Abstract
  One of the characteristics of non-insulin-dependent diabetes mellitus
  (NIDDM) is the presence of insulin resistance. Most NIDDM patients
  have a normal sequence of the insulin receptor, indicating that, if
  insulin-receptor mutations contribute to the development of NIDDM,
  they will be present only in a minor fraction of the NIDDM population.
  The goal of the present study was to examine whether insulin-receptor
  mutations contribute to the development of NIDDM. We examined 161
  individuals with NIDDM and 538 healthy controls from the
  population-based Rotterdam study for the presence of mutations in the
  insulin-receptor gene by SSCP. A heterozygous mutation changing
  valine-985 into methionine was detected in 5.6% of diabetic subjects
  and in 1.3% of individuals with normal oral glucose tolerance test.
  Adjusted for age, gender, and body-mass index, this revealed a
  relative risk for diabetes of 4.49 (95% confidence interval
  1.59-12.25) for Met-985 carriers. When the total study group was
  analyzed, the prevalence of the mutation increased with increasing
  serum glucose levels (test for trend P < .005). We conclude that the
  Met-985 insulin-receptor variant associates with hyperglycemia and
  represents a risk factor for NIDDM.

Abstract
  Objective: To study the information pregnant women recalled about the
  option of having an ultrasound examination performed during the second
  trimester and the fact that malformations can be detected and to see
  if this caused apprehension in a low-risk population. Methods:
  Standardized semistructured interviews with 100 (50 nullipara and 50
  parous) women immediately after they had a second trimester ultrasound
  examination performed. Results: Very few women felt that the verbal
  information given at the antenatal clinic fully clarified the
  intentions of an ultrasound examination whereas the majority thought
  that the written information received before the ultrasound was
  satisfactory. Less than half of the women recalled that they had been
  given professional information about the possibility that
  malformations could be detected, and a third could not recall having
  been given this information from any source. Sixty-two women thought
  that an ultrasound examination was a compulsory part of their
  antenatal care. Over two-thirds of the women were very or slightly
  apprehensive about adverse findings before the examination was
  performed. Nearly all women were satisfied with the information given
  during and after the examination and felt better afterward.
  Conclusion: These women were not informed satisfactorily about the
  aims and options of a second trimester ultrasound examination. It is
  important to give complete information and to make sure it is
  understood by the women in order to preserve their autonomy.
