Vital statistics: not vital enough

29.10.2007
The need for reliable national statistics for births, deaths, and causes of death has never been greater – but countries and developmental partners have not recognised this as a priority. These are the conclusions of Dr Prasanta Mahapatra, Institute of Health Systems, Hyderabad, India, and colleagues – authors of this second paper in the Who Counts? Series in The Lancet.

The authors look at sources of this data worldwide, and say that few developing countries have been able to improve their civil registration and vital statistics systems in the past 50 years. They say: “International efforts to improve comparability of vital statistics seem to be effective, and there is reasonable progress in collection and publication of data. However, worldwide efforts to improve data have been limited to sporadic and short-term measures.”

On cause of death data sent to WHO, for example, countries providing the highest quality (90-100% complete) include, not surprisingly, developed countries like the UK, USA, and Iceland, and also several Latin American countries such as Venezuela and Chile. Those providing no data at all include many African countries, North Korea, Andorra and East Timor in a total of 68 countries. The authors say two points from the data stand out: “First, the absence of data reported to WHO from sub-Saharan African countries and second, the mixed quality cause-of-death reporting from Europe, Asia, and Latin America. In particular, not all developed countries seem to have high quality data.”

They add: “Our collective inability to make or sustain improvements in vital statistics is due to two principal failures; first, national governments have not made civil registration systems a priority, and second, development partners do not yet recognise such systems as crucially important in the development infrastructure.”

Whilst over the last half century, the world has become healthier despite the absence of vital statistics, the authors propose: “Surely that development would have been widespread and much more equitable if people had access to intelligence about regional and local differences in disease burden?”

They conclude: “Sustainable civil registration systems that yield reliable information about the state of a population’s health should be a key development goal for all countries. It is unacceptable for us to be as ignorant about the state of a nation’s health in 50 years time as we are today.”

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
