Early pregnancy in spring linked to child's susceptibility to food allergies

Season of first trimester of pregnancy predicts sensitisation to food allergens in childhood: A population based cohort study from Finland

2010-10-20
(Press-News.org) A child's likelihood of developing food allergies can be traced back to the season during which s/he completes their first three months of life in the womb, suggests research published online in the Journal of Epidemiology and Community Health.

The Finnish researchers base their findings on just under 6000 children, all of whom were born between 2001 and 2006 and lived in one area of Finland.

Out of the total, just under 1000 were tested for sensitisation to food allergens between the ages of 0 and 4 years, with the likelihood of a positive test result rising sharply during the first year of life.

Up to the age of 4, the incidence of an allergic response to certain foods varied according to season of birth, ranging from 5% for children born in June/July to 9.5% for those born in October/November.

Around one in 10 (11%) children, whose 11th week of development in the womb had occurred during April or May were sensitised to food allergens. This compared with a rate of 6% among children who reached that stage of fetal development in December/January.

Readings of ambient pollen for the years in question showed that levels of birch and alder pollen peaked during April and May.

When narrowed down to specific allergens, the results indicated that a child whose first three months of fetal development ended in April or May was three times more likely to be sensitised to milk and eggs than those who reached this stage of development in November or December.

Research already indicates that children born in autumn or winter are more prone to eczema and wheeze, and that they have higher levels of circulating antibodies to allergens than children born in spring or summer, say the authors.

This might be because the fetus begins to produce antibodies to allergens at around the 11th week of development, and antibodies to specific allergens by around 24 weeks, they suggest.

An allergic type response is thought to be necessary for the pregnancy to continue, and in some cases this persists after birth. But the timing of the development of sensitisation has been the subject of heated debate.

Low testosterone linked to heightened risk of early death

2010-10-20
Low testosterone levels seem to be linked to a heightened risk of premature death from heart disease and all causes, suggests research published online in Heart. The finding refutes received wisdom that the hormone is a risk factor for cardiovascular disease. The researchers base their findings on 930 men, all of whom had coronary artery heart disease, and had been referred to a specialist heart centre between 2000 and 2002. Their heart health was then tracked for around 7 years. On referral, low testosterone was relatively common. One in four of the men was classified ...

SHIP protein identified as a B-cell tumor suppressor

SHIP protein identified as a B-cell tumor suppressor
2010-10-20
LA JOLLA, Calif., October 18, 2010 – Lymphoma is a cancer of the immune system. White blood cells divide again and again, spreading abnormally throughout the body. Lymphomas can arise from two types of white blood cells, T cells or B cells, which divide uncontrollably when the molecular mechanisms that keep them in check go awry. A new study led by Robert Rickert, Ph.D., professor and director of the Inflammatory Diseases Program at Sanford-Burnham Medical Research Institute (Sanford-Burnham), explores the roles of two enzymes, called SHIP and PTEN, in B cell growth and ...

Professional sports persons should drink more water

Professional sports persons should drink more water
2010-10-20
Top sports persons must always perform to their maximum capacity, making them the most vulnerable to the effects of dehydration. Now, a new study conducted by researchers from the Universidad de Castilla la Mancha (UCLM) reveals that 91% of professional basketball, volleyball, handball and football players are dehydrated when they begin their training sessions. "Dehydration negatively affects sporting performance, even when the level of dehydration is low (such as a 2% loss of body weight through perspiration)", UCLM researcher and author of the article Ricardo Mora-Rodríguez ...

2010-10-20
Two world experts in micro molluscs, Anselmo Peñas and Emilio Rolán, have made an unprecedented description in a scientific publication of a combined total of 209 snail species. Commissioned by the National Museum of Natural History in Paris, the study was unveiled in September in the French capital, and it covers the most new species from a single genus of any study to date. "Never have so many species from a single genus, nor even from a single family, been described in one single study", Anselmo Peñas, lead author of the collaborative monograph between the National ...

Study reveals how sex hormones influence right heart function

2010-10-20
In the largest human study to date on the topic, researchers have uncovered evidence of the possible influence of human sex hormones on the structure and function of the right ventricle (RV) of the heart. The researchers found that in women receiving hormone therapy, higher estrogen levels were associated with higher RV ejection fraction and lower RV end-systolic volume — both measures of the RV's blood-pumping efficiency — but not in women who were not on hormone therapy, nor in men. Conversely, higher testosterone levels were associated with greater RV mass and larger ...

Air pollution exposure increases risk of severe COPD

2010-10-20
Long term exposure to low-level air pollution may increase the risk of severe chronic obstructive pulmonary disease (COPD), according to researcher s in Denmark. While acute exposure of several days to high level air pollution was known to be a risk factor for exacerbation in pre-existing COPD, until now there had been no studies linking long-term air pollution exposure to the development or progression of the disease. The research was published online ahead of the print edition of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine. "Our ...

Adiponectin shows potential in blocking obesity-related carcinogenesis

2010-10-20
A research team from Emory University School of Medicine investigated the role between adiponectin and leptin in obesity-related carcinogenesis. Their findings, published in the November issue of Hepatology, suggest that the protein hormone adiponectin has potential for inhibiting the oncogenic actions of leptin, namely in hepatocellular carcinoma (HCC), and could offer a promising therapy for the disease. Obesity is on the rise and is associated with increased risk and progression of a number of cancers including colon, prostate, breast, and liver cancers. The World ...

Visceral adiposity index directly correlated to viral load in genotype 1 chronic hepatitis C

2010-10-20
Researchers at the University of Palermo in Italy provide the evidence that a higher visceral adiposity index score—a new index of adipose dysfunction—has a direct correlation with viral load and is independently associated with both steatosis and necroinflammatory activity in patients with genotype 1 chronic hepatitis C (G1 CHC). Details of this study are available in the November issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD). According to public health surveillance data gathered ...

Experts discuss S-equol data at ninth international symposium on role of soy

Washington, DC (Oct. 19, 2010) The latest research into the health effects and safety of a soy-based compound called S-equol was described in talks and presentations by experts at a special session on Tuesday, Oct. 19 during the Ninth International Symposium on the Role of Soy in Health Promotion and Chronic Disease Prevention and Treatment, held Oct. 16 to 19 in Washington, D.C. S-equol is a compound resulting -- when certain bacteria are present in the digestive track -- from the natural metabolism, or conversion, of daidzein, an isoflavone found in whole soybeans. ...

Experiments find bias in way analysts view firms led by black grads of prestigious universities

2010-10-20
Analysts examining a firm and the qualifications of its top management team discount the educational background of African American managers who graduated from prestigious universities while accepting the qualifications of white managers with the same college credentials, according to two experiments reported in the current issue of Organization Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS®). "We found that possessing high educational prestige was less beneficial for firms led by African Americans than for firms with ...
