(1) SUBSTANTIAL NUMBERS OF SCHOOLCHILDREN
IN SCOTLAND CARRY WEAPONS

(Association between illegal drugs and weapon carrying in
young people in Scotland: schools' survey)
http://bmj.com/cgi/content/full/320/7240/982

Substantial numbers of schoolchildren in Scotland carry
weapons, finds a schools survey published in this week's
BMJ. Weapon carrying was strongly linked to the use of
illegal drugs, the survey showed.

To investigate whether there was a link between illegal drugs
and weapon carrying, McKeganey and Norrie, of the Centre
for Drug Misuse Research and the Robertson Centre for
Biostatistics, at the University of Glasgow, surveyed over
3000 students from 20 schools across Scotland. The students
were aged from 11 to 16 years old.

Over a third of the boys and one in 12 of the girls surveyed
said that they had carried a weapon; almost four out of ten 13
to 15 year old boys reported having done so. Boys who took
illegal drugs were over three times as likely, and girls over five
times as likely, to carry weapons as their non-drug taking
peers. The more drugs that were used, the greater was the
link with weapon carrying. Almost all the boys who took five
or more different drugs reported carrying weapons,
compared with around one in two who took one drug. Types
of weapon carried included flick and Stanley knives,
machetes, razors, baseball bats, and hammers.

(2) PERSONAL DRUG PROFILES BASED ON GENETIC
MAKE-UP ALREADY IN USE

(Pharmacogenetics)
http://bmj.com/cgi/content/full/320/7240/987

In this week's BMJ, Wolf from the ICRF Pharmacology Unit
at Ninewells Hospital, Dundee, and Smith from the Imperial
College School of Medicine, review the rapid progress of
pharmacogenetics - the prescription of drugs according to an
individual's genetically determined response to them.

The authors discuss how pharmacogenetic testing will
substantially cut hospital treatment for adverse drug reactions,
currently thought to account for one in every 15 admissions.
Although not widespread in the UK, pharmacogenetic testing
is being used in some teaching hospitals and academic centres
and has been used in Scandinavia for some time. At the
moment, it is most widely used to help tailor drugs and doses
for the treatment of psychiatric illness, but is also being
developed for cancer treatments.

The ability to predict genetic variability in drug response has
been facilitated by non-invasive DNA tests which require
only a small sample of tissue, such as blood from a finger
prick or cells from a mouth wash, together with a better
understanding of the way in which drugs work, say the
authors. Although they caution that we are some way off from
a DNA chip that General Practitioners could use to identify a
total drug sensitivity profile for each patient,
pharmacogenetics should enable the design of new drugs that
are safer and more effective for particular groups of people.
"One day it may be considered unethical not to carry out
such tests routinely to avoid exposing individuals to doses of
drugs that could be harmful to them," they conclude.

(3) THREAT OF WIDESPREAD JOB LOSSES
SIGNIFICANTLY INCREASES ILL HEALTH AMONG
EMPLOYEES

(Factors underlying the effect of organisational downsizing on
health of employees: longitudinal cohort study)
http://bmj.com/cgi/content/full/320/7240/971

The threat of widespread job losses as a result of
"downsizing" significantly increases ill health among
employees, finds a study in this week's BMJ. It is not only
job insecurity that adversely affects an employee's health, but
also the increased demands and lessened sense of control
that downsizing creates, shows the research by Kivimäki and
colleagues from the University of Helsinki and University
College Medical School, London.

The research team investigated links between downsizing,
changes related to work and other aspects of life as well as
medically certified sick leave in 764 Finnish municipal
workers. The employees were studied over a period of five
years up to 1995, before, after, and during downsizing..

They found that downsizing was associated with negative
changes in work, impaired emotional support from a partner,
and increased tendency to smoke. Sick leave was twice as
likely among workers who had undergone major, rather than
minor, downsizing. The greatest proportion of the relationship
between downsizing and sick leave was explained by
increased physical demands, job insecurity, and less control
over deployment of skills and decision making.

(4) ETHNICITY DOES NOT AFFECT PRESCRIPTION OF
PAINKILLERS

(Ethnicity and prescription of analgesia in an accident and
emergency department: cross sectional study)
http://bmj.com/cgi/content/full/320/7240/980

Ethnic background has no bearing on the prescription of pain
relief, finds a study in this week's BMJ. Previous research
has indicated that white patients may receive more pain killers
than patients from other ethnic groups.

Yate and colleagues from St Bartholomew's and The Royal
London Hospital reviewed the prescription notes for white
and Bangladeshi patients with fractures of the arms or legs
who had come to the Accident and Emergency Department
at the hospital. The study took in treatment patterns for 307
patients over a period of 12 months. Three-quarters of the
patients were white; 14 per cent were Bangladeshi. The
authors found that there was no difference in the amount of
pain relief prescribed, with 81 per cent of Bangladeshi
patients and just over 78 per cent of white patients being
given analgesics.
