Science meets life and death in Venice

In Venice during this weekend, a major international organisation was launched: the

Hippocrates Society for Poetry and Medicine. This launch marks the 5^th year of the hugely successful Hippocrates initiative, which has attracted interest from 55 countries in its major awards and symposia.

Within the increasingly administered and technical world of medicine, patients often find it difficult to engage with prevention and treatment of common and serious medical problems.

Poetry provides a huge opportunity for patients to gain insight into their illness, as well as to help health professionals to understand better the concerns of their patients. 

Applications are welcome from anywhere in the world to join the Hippocrates Society for Poetry and Medicine from health professionals and patients, from poets and academics, and others who are interested in our aims.

Chemical genomics, bioactive molecules and alternative reading frame proteins: clues to sudden cardiac death

The cardiac drug flecainide was developed to prevent and treat serious ventricular tachycardia arrhythmias - very rapid heart rates which, if unchecked, can be lethal. However, in clinical trials, flecainide and its sister molecular encainide were reported to more than double the risk of sudden cardiac death.

Joint work by researchers in Chemistry and Medicine at the University of Warwick, and at the Biotech Company SEEK, is now allowing insight into how cardiac death risk might be increased by these drugs. The methods involve persuading viruses to provide a read-out on their surface of proteins related to human diseases.

In experiments just published in the Royal Society of Chemistry journal Chem Comm, we show that proteins from the heart may be read abnormally - through slippage in the letters of the genetic code for heart muscle components - these are called alternative reading frame proteins, a bit like a very simple old cipher.

Furthermore, flecainide is able to interact with a particular abnormally read protein. Previous research has linked this type of abnormality to serious side-effects of a drug used to treat the developing world parasitic infection Schistosomiasis.

There are two obvious implications of our new work. Testing for these abnormal proteins could be a new way to identify people and their family members who should be protected from risk of serious cardiac problems - for example by avoiding triggers of heart arrhythmias and by considering implantable defibrillators.

And by understanding how flecainide interacts with the abnormal protein, there may be clues to new treatments to interfere with the part of protein linked to cardiac problems.

Adverse effects of drugs can be very serious. When chosing a medicine, prescribers need to be aware of the balance of risks and benefits, and to chose the right drug for the right patient and the right disease, at the right time and for the right duration - long enough but not too long.

However our work shows an unexpected consequence of adverse effects of a drug: providing clues to new causes for disease and new ideas for treatments.

Cutting nerves in the neck to treat high blood pressure?

According to an experimental study published in Nature Communications, severing key nerves in the

neck may provide a new option for lowering high blood pressure.

Considering new approaches to treating high blood pressure (hypertension) is crucial. High blood pressure is a very common and important cause of disease and death resulting from problems with the heart, and with the blood vessels in the body and brain.

Treatment to lower high blood pressure is supposed to continue for decades. However, even by 12 months after the starting treatment, around 50% of patients are not taking their tablets regularly, if at all.

Leprosy, from old Spittals to modern times

The Berwick-on-Tweed leper hospital (Spittal) is said to have been established in 1234, at what is now called Spittal Beach. This coincides with the middle of the peak of reported leprosy in Great Britain as being 12th and 13th centuries. London eventually had 10 hospitals for lepers on main routes out of the city. The last recorded case of leprosy in London was said to be in 1559. St Bartholomew was associated with lepers in medieval times, with associations between leper hospitals and churches named after the saint both in Berwick and near London. The name leprosy is derived from the Greek word for scales (lepra), the disease discussed by Hippocrates, with evidence that it was known in Ancient Egypt at least 6000 years ago.

What was like to be leper in medieval times? Lepers lost their rights under common law, including property rights. They were excluded from places where people gathered. They had to carry a bell to warn others of their presence. They were isolated, typically sent away to remote hospitals with chapels, as lepers were expected to follow Christian rule. Hospitals were usually run by religious orders. The reportedly well-funded Berwick hospital was later by Royal Charter of James 1 of Scotland in the charge of the King's Chaplain, Thomas Lauder.

RC St Clemens, ex Benedictine Cloisters, Bad Iburg

Squints or hagioscopes allowed people with leprosy and other infectious diseases to view the sacraments from outside a church of without coming into contact with the healthy members of the congregation.

Historically people with leprosy were recognized because of resulting deformities and were shunned because of fear of contagion. Untreated, leprosy could progress, causing serious disease and deformity to nerves, skin, nerves, limbs and face, including flattening of the nose due to destruction of underlying cartilage, and associated changes in the quality of speech.

A stone tower was erected at the Spittal in Berwick in 1369 as look-out point and protection from raids over the nearby border by the Scots. The buildings were demolished and nothing above ground remains.

Red staining of organism that causes leprosy

We now know that the disease is caused by a bacterium similar to the one that causes tuberculosis: the leprosy version - mycobacterium leprae - discovered by Paul Hansen, leading to the eponymous name Hansen's disease for leprosy. There is a wide spectrum of clinical features of leprosy. The main route of spread to susceptible people considered to be by nasal droplets (from coughing and sneezing). Risk of acquiring the infection appears linked to causes of impaired cell-mediated immunity, prolonged exposure to infected patients, and to malnutrition. Although infants may develop the disease, the incubation period may be as long as 30 years.

Does leprosy still exist? The World Health Organization  records official data on leprosy from up to 120 national programmes in Member States, results published in  the WHO's Weekly Epidemiological Record. From this data, the WHO estimates that one person in 10,000 is affected by the disease (prevalence). New case detection is estimated to have decreased from around 760,000 in 2002 to around 200,000 in 2011 . With early combination drug treatment before deformity (usually for 6-12 months), outcome of the disease is much improved. However, patients with treated leprosy may still be ostracised, especially in rural communities, even if patients are known to have been treated,  because of ignorance about the low risk of disease transmission and about the success of treatment: people are considered no longer infectious after around one week of treatment and it is estimated that over 10 million people estimate cured of leprosy in past 2 decades.

Sharpening memory and cocoa - how interested should you be?

Farzaneh Sorond and colleagues from Harvard and the Mass. General Hospital have attracted worldwide interest in their study published in the US journal Neurology "Neurovascular coupling, cerebral white matter integrity, and response to cocoa in older people". 

Listen to interview on the story on BBC local radio
 
The theme of the interest - from the LA Times to the Belfast Telegraph - is that cocoa "not only soothes the soul, but might also sharpen the mind'.

Fruit of the theobroma cocoa tree: Corti et al. Circulation 2009 

Why even think that it might? The authors drew on two background concepts:
- Earlier research using sophisticated brain imaging had reported that cocoa intake is associated with an increase in blood flow to the brain; and brain blood flow is linked to intellectual capacity.
- And cocoa contains flavonols, bioactive chemicals present in many foods associated with measures of healthy cardiovascular health, including increasing blood flow to the gray matter of the brain.
The question asked by the researchers was whether previous interest in chocolate containing products and better brain function might be explained by flavonol effects. 
To address this they carried out a study in which the design was high quality with regard to a possible effect of flavonols on 2 measures - brain blood flow and a test they used to assess memory.
What did they find? No difference in the effects of flavonol-rich vs low in flavonol cocoas as 2 cups per night for 30 days.
However, they reported a significant improvement in blood flow and in the intellectual function test by 30 days.
Should we all now start drinking large amounts of cocoa? Not yet based in this interesting but small study. To consider my question in a different way, key points arising from this work are:
- does cocoa sharpen the mind?
- does it protect from dementia?
- does it help people with dementia?
With these points in mind:
- the study was small - only 60 participants included and only 18 of these were noted to have improvements with regular cocoa
- the study was only for 30 days - more work would be needed to show whether these apparent benefits would be sustained
- the study was performed in older people - average age 73, who already had risk factors for cardiovascular disease - not safe to generalise study findings to other age groups and to people without cardiovascular risk factors.
- the 70% of volunteers who had normal blood flow and managed the test well at baseline should no improvement with cocoa
- the study was designed to test an effect of flavonols. However there was no time control for the effect of cocoa - e.g. vs other hot drinks. The authors cannot therefore rule out a time effect on their results e.g. people not managing the test well at the start doing better simply through  the initial practice
- the tests of brain function were 'Trailing Making Tests' ie involved a timed 'joining the dots' test. It would be important to confirm that more real world aspects of brain function were also improved
- no patients with dementia were included - further studies would be needed to show whether patients with dementia would also benefit and that any benefits were helpful for activities of daily living 
Thus results of the study could be explained as an artefact of the study design - ie not be due to the cocoa. At best they only applied to people with identified cardiovascular factors who also already had impaired brain blood flow and difficulty in performing the type of mental activity tests used by the researchers. 
And the concern about large amounts of cocoa is the associated increase in dietary sugar and fat intake of typical Western milky cocoa drinks. Neither are good for cardiovascular health, as they increase risk of overweight, high cholesterol, diabetes and high blood pressure. To compensate for those risks, the researchers under the strict conditions of the study made sure their volunteers made appropriate adjustments in other parts of the diet to balance sugar and fat intake over the month. In real world use, even if cocoa were confirmed to be helpful for the brain, it would be very important that people increasing their cocoa intake were very careful to avoid these unintended consequences of increased cocoa intake. Of note the researchers were not studying cocoa with added cream and marshmallows - not good for the circulation.
What about different sources of chocolate in cocoa? Not addressed by the researchers - except that they appeared to show at least that any benefits were not related to the types of flavonol they studied.
And how about eating chocolate instead? Again - not studied by the researchers. And in previous observational research on chocolate, there was an apparent benefit on heart disease protection from very small amounts (chocolate 1-3 times per month) with larger amounts reported to be harmful for the heart.
As a final thought, one of the reported uses by ancient Aztecs and Incas of chocolate drinks was as sedatives in religious rituals. Another explanation for the study findings is that calming effects of cocoa ('soothing the soul') reduced anxiety during the tests as a contribution to the observed improvements in brain blood flow and test performance with the drinks.
