According to a study conducted by the Consumer Reports on the effect of caramel colouring used in soft drinks, the daily consumption of fizzy drinks is more dangerous than we thought.

The chemical process that takes place with the manufacturing of caramel colouring produces a carcinogen that could be raising the risk of cancer, suggests an analyst.

The laboratory tests on 11 different soft drinks revealed that one can a day could be enough to expose a consumer to potentially cancer-causing levels of the chemical 4-MeI, which is short for 4-methylimidazole. Surprisingly however, the levels of 4-MeI varied in samples of the same type of fizzy drinks. Tyler Smith, the lead author of the Johns Hopkins study, the team that led the Consumer Reports researchers, said that “For example, in diet drinks, certain samples had higher or more variable levels of the compound, while other samples had very low concentrations”.

Experts believe that a simple breath test could help doctors detect and diagnose Parkinson’s disease.

The test looks for a unique signature of chemicals in exhaled breath.
Small studies in volunteers have begun and early findings suggest the test can identify those with the debilitating brain condition.
Larger trials are now planned to see if it could truly be a useful test, particularly for picking up Parkinson’s in its earliest stages.
Currently, no test can conclusively show that a person has Parkinson’s.

Instead, doctors reach a diagnosis based on a person’s symptoms and test results – such as brain scans to rule out other diseases.
At this stage, Parkinson’s may already be fairly advanced.
Identifying it earlier would be beneficial because it would mean treatment could be given sooner.

Parkinson’s disease is a progressive condition where there is gradual loss of nerve cells from the brain.

And it is thought that this degradation leaves a chemical footprint in the body that could potentially be used in diagnostic tests.

Scientists have been exploring different ways of finding such biomarkers, including looking in blood, spinal fluid, and exhaled breath.

The breath test looks for traces of volatile organic compounds or VOCs in the air we exhale.

In a small trial in Israel with 57 people, some with Parkinson’s and some without, the test could identify the individuals with Parkinson’s by looking for distinctive patterns of VOCs.

It also appeared to distinguish between different sub-types of the disease based on the presence and quantity of different VOCs.

The charity Parkinson’s UK and experts at the University of Cambridge were intrigued by these early findings and are now setting out to do a bigger study involving 200 volunteers from England.

Dr Simon Stott, who is part of this UK team and will be working alongside the scientists from the Israel Institute of Technology, in Haifa, said: “We would like to find biomarkers that can identify patients early.

“A breath test would be really appealing because it’s non-invasive, non-painful and can be done in seconds.

“While it wouldn’t replace what doctors already do, it could be a useful diagnostic tool to help them.”

The biggest hope is that there may be molecules in the breath of people with Parkinson’s which throw up new options for drug targets.

The researchers say they have many years of work ahead of them before they will know if the test can be used in clinics.

Frequent eye movements in babies could be a clue to whether they will develop an autism spectrum disorder, a Medical Research Council study suggests.

Using eye-tracking technology, researchers measured 100 six-month-old babies looking at a static image.

Those later diagnosed with ASD moved their eyes around more often, which could be a cause of learning problems.

Women with type 1 diabetes face a greater risk of dying from a range of diseases compared with men with the same condition, research suggests.

This is particularly the case when it comes to heart disease, Australian scientists report.

They say their findings could have “profound implications” for how women with the condition are treated.

Charities warn that the study highlights a failure of care that needs to be changed urgently.

Type 1 diabetes is a disorder that often appears in childhood. Patients’ pancreases are unable to produce the insulin needed to convert sugar and other foods into energy.

Compared with the general population, people with type 1 diabetes have a shorter life expectancy. But researchers say it hasn’t been clear until now whether this affects men and women equally.

To investigate this, scientists from the University of Queensland analysed data from more than 26 studies involving some 200,000 people with the disease.

Overall, they found women had a 40% increased risk of deaths from all causes.

They faced a greater risk of stroke than men and were also more likely to die from kidney disease.

No-one is entirely sure what lies behind these trends.

Simon O’Neill, of Diabetes UK said there had been evidence to suggest changes to girls’ bodies during puberty could make it more difficult for them to get their diabetes under control.

He added: “We need the NHS to urgently improve diabetes care so that all people are offered care that is tailored to their individual needs and so are able to manage their condition effectively and reduce their risk of devastating complications and early death.

“With the right care and support in place there is no reason why people with type 1 diabetes – both men and women – can’t live long, healthy lives.”

Sarah Johnson, from type 1 diabetes charity JDRF, said: “I’m angry. These findings show that type 1 diabetes care is failing and these failings should be addressed urgently for everyone with the condition – not just women.”

Prof Rachel Huxley, lead researcher on the project, said in a statement: “The marked difference between the sexes for vascular-related disease is likely to have profound clinical implications for how women with type 1 diabetes are treated and managed throughout their lives.”

The study appears in the journal Lancet Diabetes and Endocrinology.

The media in Saudi Arabia has caused confusion among expats this week as it had reported that the deadline for registration of health insurance and biometrics was to be extended three months, until April this year.

The Passport Office has strongly refuted these claims and assured expats that, contrary to the media reports, the deadline for registration has not been extended, and that it has now passed. The deadline for registering biometrics in Saudi Arabia was the 21st January this year.

It has now become mandatory for all male and female expats, and their dependents over the age of fifteen, to have their biometrics registered with the Passport Office of Saudi Arabia. Residency permits (iqamas) are issued to those expatriates who live in Saudi Arabia on an employment visa. These will now not be issued or renewed without proof of health insurance and biometrics, without an iqama, entry and exit will be denied to expats. Once fingerprints have been recorded on the Automated Central System (ACS), they do not need to be recorded again, although they will be checked upon exit and entry to the country and upon renewal of the iqama, which is only valid for one to two years.

It must be noted by expats living in the country that they are liable to face a considerable fine if they have not already registered their biometrics, and their exit visas will not be granted until this has been done. Information on where to go to register can be found on the passport control website.
