(1) MEN WITH PROSTATE CANCER WANT
SCREENING DESPITE DOUBTS OVER
EFFECTIVENESS OF TREATMENT

Most men with prostate cancer strongly advocate routine
testing for prostate specific antigen (PSA), despite
evidence that aggressive screening and treatment does not
reduce deaths, according to two studies in this week's
BMJ.

In the first study, researchers at the University of Oxford
interviewed 52 men with suspected or confirmed prostate
cancer.

All but four men were keen to see others, including their
own friends and sons, have a PSA test. Their reasons
included the belief that early diagnosis would reduce
death, improve quality of life, and save the NHS money.
The four men who opposed screening knew that treatment
had not been proved effective and accepted that this was
a deterrent to screening.

Screening for prostate cancer has serious disadvantages,
say the authors. As such, general practitioners in the UK
have been advised to ensure that men who have a PSA
test are making an informed choice. Policy makers,
politicians, and doctors need to understand why people
want wider access to PSA testing so that they can find
better ways of communicating information about risk, they
conclude.

In the second study, researchers in the United States
compared the Seattle-Puget Sound region, where
intensive screening and treatment for prostate cancer were
adopted early, and Connecticut, where adoption was
slower.

During 1987-90, men in Seattle were five times as likely
to undergo PSA testing and twice as likely to undergo
biopsy. Rates of radical surgery and radiotherapy were
also substantially higher. However, over 11 years of
follow up, prostate cancer death rates were similar in the
two areas.

Longer follow up may be necessary to fully assess the
outcome of this natural experiment, say the authors.
Meanwhile, ongoing trials assessing the effectiveness of
screening and treatment for prostate cancer should be
supported.

(2) NEW APPROACH TO INSULIN TREATMENT
IMPROVES PATIENTS' LIVES

(Training in flexible, intensive insulin management to enable
dietary freedom in people with type 1 diabetes: dose
adjustment for normal eating (DAFNE) randomised
controlled trial)
http://bmj.com/cgi/content/full/325/7367/746

Training patients with diabetes to adjust their insulin doses
to match their food choices, improves diabetes control
and quality of life, finds a study in this week's BMJ.

This approach has been developed in Germany, but has
not been widely adopted elsewhere. Patients in the UK
often have impaired quality of life and a high risk of
diabetic complications. Researchers in Sheffield, London
and North Tyneside set out to test this approach in the
UK with the dose adjustment for normal eating (DAFNE)
trial.

They identified 169 adults with type 1 diabetes attending
hospital clinics in Sheffield, Northumbria, and London.
Patients either attended a five day training course, or
continued to receive usual care for six months as controls
and then attend a course.

The course trained patients to adjust their insulin doses to
match their food choices, rather than being expected to
sacrifice dietary preferences to fit in with prescribed insulin
doses. Participants in DAFNE had improved glycaemic
control and, despite intensified insulin treatment, reported
greater satisfaction with treatment, general wellbeing, and
quality of life.

The personal importance of these improvements are
illustrated by patient's comments. One said, "I now feel
able to travel abroad without worry about not eating or
eating on time." Another said, "I have found my whole
lifestyle and outlook on life has improved."

Skills training enables patients to fit diabetes into their lives
rather than their lives into diabetes, and can be applied
successfully across different healthcare systems, say the
authors. This approach has the potential to enable more
people to adopt intensive insulin treatment and is worthy
of further investigation, they conclude.

(3) SMALL BABIES ARE MORE LIKELY TO BE
STRESSED ADULTS

(Association between psychological symptoms in adults
and growth in early life: longitudinal follow up study)
http://bmj.com/cgi/content/full/325/7367/749

Small size at birth and slow growth in early childhood are
associated with higher levels of psychological distress in
adults, finds a study in this week's BMJ.

Cheung and colleagues studied the psychological health of
over 9,000 British adults born in 1958 until age 42 years.
Birth weight and growth in childhood was measured and
factors such as father's social class and maternal smoking
were accounted for.

They found that people who had a higher birth weight and
a faster weight gain from birth to 7 years old had a lower
level of psychological distress into middle age.

Previous studies could only demonstrate such a relation up
to the age of 26 years, they conclude.

(4) SHOULD WE HELP TO CREATE DISABLED
BABIES?

(Deaf lesbians, "designer disability," and the future of
medicine)
http://bmj.com/cgi/content/full/325/7367/771

Should genetic tests be offered to couples seeking to have
a child to allow them to select for disability? Many would
see deliberately creating disabled babies as the most
perverse manifestation of creating designer babies but, in
this week's BMJ, Julian Savulescu argues that there may
be good reasons for acceding to such requests.

We offer genetic tests to couples to allow them to select
the child ? from the possible children they could have ?
with the best opportunity of having the best life. But how
should we decide what constitutes "the best life
prospects?"

Each couple makes its own decision about whether or not
to have a child with Down's syndrome. "But my value
judgement should not be imposed on couples who must
bear and rear the child. Nor should the value judgement of
doctors, politicians, or the state be imposed directly or
indirectly (through the denial of services) on them," he
says.

There are good reasons to engage people in dialogue
about their decisions, to try to persuade them with
arguments, but in the end we should respect their
decisions about their own lives.

Reproduction should be about having children who have
the best prospects, but we must give individual couples
the freedom to act on their own value judgement of what
constitutes a life of prospect. That includes the freedom to
do what others disapprove of or judge wrong, provided
the exercise of freedom does not harm others, he writes.

As rational people, we should all form our own ideas
about what is the best life. But to know what is the good
life and impose this on others is at best overconfidence ?
at worst, arrogance, he concludes.
