Large families and animals keep allergies at bay

Cohort study of sibling effect, infectious diseases, and risk of atopic dermatitis during first 18 months of life BMJ Online First



Having siblings, keeping a pet, or living on a farm helps protect infants against the development of atopic (allergic) diseases, but early infections increase the risk, according to new research from Denmark. This study will be available on bmj.com on Friday 30 May 2004.

Researchers conducted four separate interviews with over 24,000 pregnant women (twice during their pregnancy and again when their child was 6 and 18 months old).


Information on atopic dermatitis and infections before 6 months of age were recorded. Data on factors associated with exposure to microbes, such as number of siblings, pet keeping, living on a farm, and attending day care, were also collected.

The risk of atopic dermatitis increased with each infectious disease before 6 months of age. This contrasts with the common belief that infectious diseases early in life may protect against the development of allergic diseases.

However, the risk of atopic dermatitis decreased with each additional exposure to three or more siblings, day care, pet ownership, and farm residence. This protective effect remained after adjusting for number of infectious diseases, suggesting that it is established independently and very early in life, say the authors.

These findings support the importance of microbial exposure for preventing atopic dermatitis, but challenge the hypothesis that infectious diseases in infancy protect against its development, they conclude.

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
