Hunger 'links asthma and obesity'

Tuesday, 17 July 2007

Researchers say they may have worked out why the obese are more prone to asthma than those of normal weight.

The link between the two conditions is well-established, but the relationship is ill-understood.

Now scientists at King's College London say they have pinned down a protein which contributes to inflammation of the lungs as well as increasing hunger.

The study in the Proceedings of the National Academy of Sciences said further research was now needed.

Mechanism mystery


Red tide noxious for asthmatics

Jan 10, 2007

SARASOTA, FL, United States (UPI) -- The 'red tide' algae bloom off Florida`s coast can exacerbate symptoms in asthma sufferers on nearby beaches, researchers say.

The blooms, which concentrate on Florida`s shorelines one a year, produce airborne toxins called brevetoxins, said The toxins get into the air after leaking into the water from ruptured algal cells.


How Acid Reflux Can Worsen Your Asthma

Asthma is a chronic lung condition that is characterized by difficulty in breathing, wheezing, and mucus accumulation. People with asthma have extra sensitive or hyper-responsive airways. During an asthma attack, the airways become irritated and react by narrowing and constricting, causing increased resistance to airflow, and obstructing the flow of the air passages to and from the lungs.


Carpets in workplace linked to adult asthma risk

NEW YORK (Reuters Health) - Being exposed to certain types of surface materials at work appears to increase adults' risk of developing asthma, a new study shows.

"These findings underline the need to consider the health aspects of materials used in floor, wall, and other indoor surfaces," Dr. Jouni J. K. Jaakkola of the University of Helsinki in Finland and colleagues conclude in the American Journal of Epidemiology.


A Study Links Trucks’ Exhaust to Bronx Schoolchildren’s Asthma


Published: October 29, 2006

In New York City, air pollution levels have typically been monitored by inanimate objects, at more than a dozen locations around town. But in the South Bronx, from 2002 to 2005, air pollution monitors went mobile. They went to the playground, to the gritty sidewalks, even to the movies.


HK's bad air linked to childhood asthma

Thu Sep 21, 2006

HONG KONG (Reuters) - Hong Kong's bad air may be responsible for a significant jump in children being admitted to hospital for asthma, a six-year study has found.

The study, published in the June issue of the medical journal Clinical and Experimental Allergy that is soon to be distributed, is certain to heighten concerns over the city's worsening air pollution.

Companies in Hong Kong have blamed the territory's air pollution for driving away some expatriates and making it more difficult to recruit foreign workers in recent years.


Important Antioxidants for Asthma Relief

Free radicals play a big role in inducing bronchoconstriction and elevating mucus secretion in asthmatic. For this reason, it is a good idea if you have asthma to build up your use of antioxidants. Two antioxidants that are necessary for reducing asthmatic conditions are selenium and Glutathione.

The other important antioxidants and minerals for asthma are vitamin C, vitamin E, magnesium, B12, B6, quercetin


Asthma tied to sleep apnea in women

Fri Sep 1, 2006

By David Douglas

NEW YORK (Reuters Health) - Asthma appears to almost double the risk of symptoms of obstructive sleep apnea in young mothers, Ohio-based researchers report.

"In a large population-based cohort of young women, we found that women with asthma are twice as likely to have symptoms of obstructive sleep apnea as compared to women without asthma," lead investigator Dr. Maninder Kalra told Reuters Health.
