Researchers establish link between cold climates, poor housing and high blood pressure

21.08.2002


People living in the north and west of Britain in poor quality housing are at a significantly greater risk of high blood pressure than those living in warmer climates, and better quality housing, say scientists today.



The research, published recently in the International Journal of Epidemiology, shows how scientists from Imperial College London, the University of Edinburgh and University College London identified an `inverse housing law` in Britain, whereby people in colder climates such as the north and the west were on average a third more likely to live in poorer quality housing than those in the south and the east.

The researchers discovered a link between the `inverse housing law`, and the risk of high blood pressure. Those who lived in colder climates, in poor quality housing, could be up to 45 per cent more likely to develop high blood pressure.


Dr David Blane, from Imperial College London at Charing Cross Hospital, says: "This research has shown that there is a serious problem with a significant proportion of the housing stock in Britain. Those living in the worst climates are often also in the poorest quality housing. Many of the houses in the north and west of Britain, have been identified as being of poor quality.

"The findings of this study show how long term exposure to an adverse environment, can have a serious impact on health. The widespread existence of poor quality housing, unable to fully protect against the Britain`s climate, has been shown to have a significant impact on health. It is not possible to alter Britain`s climate, but an investment in housing may provide considerable health benefits."

High blood pressure is defined in an adult as a blood pressure greater than or equal to 140 mm Hg systolic pressure or greater than or equal to 90 mm Hg diastolic pressure. If untreated, high blood pressure increases the risk of coronary heart attack and stroke.

Im Focus: The fastest light-driven current source

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.

Graphene is up to the job

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
