Peanut in household dust linked to peanut allergies, especially for children with eczema
2014-11-19
(Press-News.org) Exposure to peanut proteins in household dust may be a trigger of peanut allergy, according to a study published today in the Journal of Allergy and Clinical Immunology.
The study was conducted in 359 children aged 3-15 months taking part in the NIH-sponsored Consortium for Food Allergy Research (CoFAR) study. These children were at high risk of developing a peanut allergy based on having likely milk or egg allergy or eczema. The study found that the risk of having strong positive allergy tests to peanut increased with increasingly higher amounts of peanut found in living room dust.
"The relationship was especially strong among children with more severe atopic dermatitis (eczema), suggesting that exposure to peanut in the environment through an impaired skin barrier could be a risk," said Hugh Sampson, MD, Professor of Pediatrics, Dean for Translational Biomedical Sciences at the Icahn School of Medicine, Director of the Jaffe Food Allergy Institute at The Mount Sinai Hospital, and the Principal Investigator for the CoFAR.
Scott H. Sicherer, MD, a lead investigator for the study and the Elliot and Roslyn Jaffe Professor of Pediatrics at the Icahn School of Medicine at Mount Sinai, noted that it is too early to make recommendations based on these results and that more research is needed. "We need to see if early interventions, such as earlier food consumption, improving the damaged skin barrier, or reducing household exposure will counter the development of the allergy."

The study was performed in collaboration with 4 other sites in the United States and with researchers at King's College in London.

UCLA biochemists have created the largest-ever protein that self-assembles into a molecular "cage." The research could lead to synthetic vaccines that protect people from the flu, HIV and other diseases.
At a size hundreds of times smaller than a human cell, it also could lead to new methods of delivering pharmaceuticals inside of cells, or to the creation of new nanoscale materials.
The protein assembly, which is shaped like a cube, was constructed from 24 copies of a protein designed in the laboratory of Todd Yeates, a UCLA professor of chemistry and biochemistry. ...

A new treatment for Marfan syndrome, a rare genetic disease that can lead to heart problems, works as well as the currently recommended medical therapy, beta blockers, according to an article in the New England Journal of Medicine.
Angela Sharkey, M.D., professor of pediatrics at Saint Louis University, and a study author, said researchers found losartan, which had been more effective in an animal model of Marfan syndrome, was equally effective to a high dose of the beta blocker atenolol.
"While there may be certain patients who respond better to one drug or another, ...

Researchers from the University of Melbourne found unlike other laser treatments, this new faster laser did not result in damage to the retina, the sensitive light detecting tissue at the back of the eye.
Associate Professor Erica Fletcher from the Department of Anatomy and Neuroscience said this was the first report detailing how this new laser treatment may improve eye health in those with AMD. In the early stages, the disease is characterised by the presence of small fatty deposits called drusen and thickening in a membrane at the back of the eye.

Barcelona, Spain: A new drug that targets not only common cancer-causing genetic mutations in patients with non-small cell lung cancer (NSCLC), but also a form of the mutation that causes resistance to treatment, has shown promising results in patients in a phase I/II clinical trial. The research will be presented today (Friday) at the 26th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Spain.
Approximately 10-15% of Caucasian and 30-35% of Asian patients with NSCLC have a mutation in the epidermal growth factor receptor (EGFR), which ...

If it's help a woman needs, maybe she should wear high heels. That's the message from Nicolas Guéguen of the Université de Bretagne-Sud in France, after he observed how helpful men are towards women in high heels versus those wearing flat, sensible shoes. The study, published in Springer's journal Archives of Sexual Behavior, is the first ever to investigate how the height of a woman's shoe heel influences how men behave towards her.
Research across various cultures has shown at length how important physical features, such as body size and the style and color ...

Approximately 40 percent of the earth's surface is covered by drylands in which average annual precipitation is lower than evaporation. The changes projected to unfold in these areas in the course of climate change are alarming. Greater variations in annual and seasonal precipitation will lead to more frequent droughts and, presumably, longer drought periods. This means that drylands are among those areas most severely affected by climate change.
Research has thus far not adequately addressed the question of how strongly annual plant growth in pasture landscapes - hence ...

Time ravages mountains, as it does people. Sharp features soften, and bodies grow shorter and rounder. But under the right conditions, some mountains refuse to age. In a new study, scientists explain why the ice-covered Gamburtsev Mountains in the middle of Antarctica looks as young as they do.
The Gamburtsevs were discovered in the 1950s, but remained unexplored until scientists flew ice-penetrating instruments over the mountains 60 years later. As this ancient hidden landscape came into focus, scientists were stunned to see the saw-toothed and towering crags of much ...

Researchers from China, the Philippines and LSTM have today published a new systematic review of reminder systems to improve patient adherence to tuberculosis (TB) treatment. Reminder systems include prompts in advance of a forthcoming appointment to help ensure the patients attend, and also actions when people miss an appointment, such as phoning them or arranging a home visit. This review is the latest in a suite of reviews produced by authors from the Cochrane Infectious Diseases Group, hosted at LSTM, evaluating interventions to improve adherence to TB treatment. Effective ...

Washington, D.C. - November 19, 2014 - Lumosity is presenting new research today at the 2014 Society for Neuroscience conference on how lifestyle factors such as sleep, mood and time of day impact cognitive gameplay performance. The study, titled "Estimating sleep, mood and time of day effects in a large database of human cognitive performance," analyzed over 60 million data points from 61,407 participants and found that memory, speed, and flexibility tasks peaked in the morning, while crystallized knowledge tasks such as arithmetic and verbal fluency peaked in the afternoon. ...

An international team of scientists, coordinated by a researcher from the U. of Granada, has found that seed dormancy (a property that prevents germination under non-favourable conditions) was a feature already present in the first seeds, 360 million years ago.
Seed dormancy is a phenomenon that has intrigued naturalists for decades, since it conditions the dynamics of natural vegetation and agricultural cycles. There are several types of dormancy, and some of them are modulated by environmental conditions in more subtle ways than others.
