New tuberculosis test scoops top prize at Medical Futures competition

08.11.2005


An inexpensive and rapid test for tuberculosis (TB) which could be used in developing countries has won first place in the Best Innovation to Improve Global Healthcare category of the Medical Futures Innovation Awards. It also scooped the overall prize at the awards ceremony held last week in London.



The test, known as MODS (Microscopic Observation Drug Susceptible Assay) is able to confirm the presence of TB from sputum samples in one week on average, taking one third to one quarter of the time of a standard TB test. At the same time, the new test is able to spot if the TB is drug resistant which is five to ten times faster than existing tests. The test costs $2 to perform compared with around $30 to $40 for a standard test.

Dr David Moore, from Imperial College London, and the winner of the Award said: “This test can be carried out using cheap and readily available tools and requires relatively little training or expertise. This is particularly important in developing countries which may not have the infrastructure we take for granted in the developed world.”


Each year around 8 million new cases of TB are diagnosed, and 1.7 million people die from TB, often as a result of delayed diagnosis and through not being able to spot if the TB is drug resistant.

Working with colleagues from Peru’s National TB Programme, the Universidad Peruana Cayetano Heredia, AB PRISMA, and John Hopkins Bloomberg School of Public Health, the team realised many TB patients were dying unnecessarily largely due to an inability to cheaply and quickly diagnose TB. They have now completed proof of principle studies, evaluated the test in large-scale field trials, and are now looking at strategies for implementation and roll-out to optimize impact and cost-effectiveness.

Professor Jon Friedland, from Imperial College London, who helped develop the test, added: “TB is a major cause of mortality in the developing world, and eradicating it has been made difficult through a lack of inexpensive diagnosis equipment which can be deployed quickly and easily. The MODS test provides a simple solution to this, and I am very pleased that this has been acknowledged by winning this very prestigious award.”

Professor Stephen Smith, Principal of the Faculty of Medicine at Imperial College London said: “David and Jon’s work is an excellent example of how organisations such as Imperial can really help make a difference. The development of a low cost practical solution which can be rolled out in countries with a limited infrastructure could make an enormous difference in eradicating TB.”

The work was funded by the Wellcome Trust.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
