Stress Influences Our Moral Behaviour

All of us are stressed, every now and then. Acute stress can have a profound impact on the human body and mind: both physical and psychological stressors affect the autonomic nervous system and the hypothalamic–pituitary–adrenal axis, leading to changes in cardiovascular and neuroendocrine measures. Stress also is shown to affect cognitive functions like memory and attention. Just recently, however, research discovered that acute stress also can influence our moral behaviour.

Ethical Enhancement

Scientists in America have found a way to reduce crime amongst some high risk groups by 30-40%. It involves a simulation of crime scenes where the victim is a hologram representing the potential criminal in question, followed by discussion with a trained therapist. The experience causes the subject to feel greater empathy and reduces violent crime. We should introduce this therapy now, as a matter of priority.

There is no such therapy, sadly. But there is something which promises the same effects in some groups. Ritalin. A Swedish study found that taking ADHD medication significantly reduced the criminality rate amongst those with ADHD: by 32% in men, and 41% in women. ADHD has itself been associated with an increase in criminality.

Some people will argue that this is a therapy for ADHD, not an enhancement. But ADHD is not a disease like cancer – it is likely a variant of normal functioning involving lower levels of impulse control and attention.

Ritalin, Adderall, Modafenil are all taken by thousands of professionals and students to enhance performance, in a similar way to caffeine. The film Limitless was loosely based on modafenil (in fact, Modafenil doesn’t appear to have such a dangerous side effect profile as is portrayed in the film, though there are as yet no long term studies of normal people). Ongoing research into Alzheimers disease and other impairments will lead to other drugs which enhance normal cognition.

The Ethics of Private Payment for Health Care: The Example of Vaccination

30  July. This blog is an extended version of the post ‘Vaccines: All or Nothing’ (posted 29 July). 

A vaccine which would protect children from Meningitis B has been rejected by the Joint Committee on Vaccination and Immunisation (JCVI) as not cost effective, despite the fact the cost is not yet known.

The Department of Health’s director of immunization explained:

“This is a very difficult situation where we have a new vaccine against meningitis B but we lack important evidence. We need to know how well it will protect, how long it will protect and if it will stop the bacteria from spreading from person to person.

“We need to work with the scientific community and the manufacturer to find ways to resolve these uncertainties so that we can come to a clear answer.”

A call for more research is a standard answer to many dilemmas in healthcare, though perhaps one which is easy to ignore. As far as we know there are no current plans to ensure that this research takes place but the vaccine has already been found to be safe, and according to the BBC, “tests have suggested the vaccine is effective against 73% of the different strains of the disease”.

Resource allocation is an inevitable part of any health care system, and perhaps especially so in the NHS. Whilst we would like to provide all available treatments, prioritizing according to effectiveness and cost is necessary, though the exact method of calculating this (currently Quality Adjusted Life Years, or QALYs) is of course under intense debate and scrutiny.

In the meantime, children continue to suffer avoidable, lifelong disability due to infection with Meningitis B. I argue with Lach de Crespigny in a forthcoming paper on homebirth that actions (or failures to act) taken today which cause harm in the future are as wrong as if that harm were realized today. The plight of these children and adolescents should not be ignored.

Put simply, if you could prevent a child from getting brain damage, now or in the future, at little cost to you, you ought to perform that act.

One possible way forward would be to allow parents to pay for the vaccination of their child, at whatever price the company sets, just as holiday vaccinations can be provided by the NHS at a cost to the patient. Vaccinated children could be monitored and their data recorded. Not only would this generate the data that would establish how high up funding agendas this vaccine should be, but some individual children would be prevented from suffering this deadly and debilitating disease. To increase take up, the company would be under market pressure to keep the price as low as possible.

Three person IVF

It was announced yesterday that the government is moving towards allowing so-called three person IVF for the creation of embryos free of mitochondrial disease.

The mitochondria are tiny organelles in the body of the cell, concerned with important energy functions, and which contain a small amount of DNA. They are present in the egg, but not in the sperm, and are passed down the female line, more or less unchanged, from mothers to all her offspring, and then from daughters to grandchildren and so on. In some cases, women can suffer from various mitochondrial disorders, which they are at risk of then passing on to their children. These disorders may be relatively mild, but in perhaps 5 – 10 cases a year in the UK, babies will be born with very serious disease.

There are a couple of ways of doing the new procedures, but basically the new proposed techniques take the egg of an affected woman and remove the nuclear DNA (the vast majority of our DNA which goes to shape our basic features). A donated egg is also taken, its nuclear DNA removed, leaving behind the healthy mitochondrial DNA. The nuclear DNA of the affected woman is then transplanted into the body of the healthy egg, resulting in an egg which has the DNA of the affected woman, minus the tiny fraction of mitochondrial DNA concerned with cell energy functions.

The Department of Health has backed this procedure after the HFEA conducted public consultations earlier this year; the HFEA reported broad public support for the techniques.  The Chief Medical Officer is now urging the drafting of regulations to allow the procedure to be approved by Parliament as soon as possible. There are hopes that the first patients could be treated as soon as 2014.

Mitochondrial disease can be really severe and lead to great suffering and early death. So why would there be any doubts about the use of such techniques?

Are cyborgs the future of humanity?

Yesterday’s Observer features two pieces about human enhancement in the prospect of the FutureFest festival in London in September (see here and here). The articles mention Bertolt Meyer, a Swiss man born without a left hand who was recently fitted with a state-of-the-art bionic one (which he controls from his iPhone), and include quotes from well-know authors associated with the topic of human enhancement, such as Nick Bostrom and Andy Miah.

The Cultural Cost of Placebo

A recent poll says that nearly all General Practitioners in the UK have given placebos to at least one of their patients. The story can be seen here: http://www.bbc.co.uk/news/health-21834440   Everyone loves placebos. If you are a scientist, placebo shows an incredible feat of the human body, and interesting interactions between our psychology and the biology… Read More »The Cultural Cost of Placebo

The Way Forward: Mapping Brains and Finding Direction

According to a recent report in the New York Times, the United States government will soon announce plans to fund the Brain Activity Map. Modelled on the highly successful Human Genome Project, the Brain Activity Map is an effort to identify functional networks of neurons, possibly leading to a full understanding of how mental processes… Read More »The Way Forward: Mapping Brains and Finding Direction

Too long in gestating: an overdue inquiry into the Abortion Act

Whatever your view of abortion, there are too many abortions, and too many of them are too late. Even abortion’s fiercest advocates don’t pretend that it’s a Good Thing – just the lesser of two evils.

In 2010 there were 189,574 abortions in England and Wales – an 8% increase in a decade. The tightly policed regime envisaged in 1967, when the Act became law, hasn’t existed for ages, if indeed it ever did. There is abortion on demand, whatever the statute book says.

1967 was a long time ago. There have been many medical advances and societal changes since then. It’s time to take stock of the Act.

That’s what a recently announced cross-party commission, to be chaired by Fiona Bruce MP, will do.

It will focus, rightly, on two issues: medical advances and attitudes to discrimination.Read More »Too long in gestating: an overdue inquiry into the Abortion Act

Do we want “genetically modified children”? Yes, of course!

The agency that regulates fertility treatment and embryo research in the UK, the Human Fertilisation and Embryology Authority (HFEA), has asked for public views on two possible new forms of fertility treatment that promise to prevent the transmission of mitochondrial diseases to children. These diseases can be extremely severe, leading to (among other things) diabetes, deafness, progressive blindness, seizures, dementia, muscular dystrophy, and death.
