Vegetables, nuts can beat the blues

To reach the conclusion, Almudena Sánchez-Villegas, University of Las Palmas de Gran Canaria, Pamplona, Spain, and colleagues studied 10,094 healthy Spanish participants who completed an initial questionnaire between 1999 and 2005.

Participants reported their dietary intake on a food frequency questionnaire, and the researchers calculated their adherence to the Mediterranean diet based on nine components (high ratio of monounsaturated fatty acids to saturated fatty acids; moderate intake of alcohol and dairy products; low intake of meat; and high intake of legumes, fruit and nuts, cereals, vegetables and fish).

After a median of 4.4 years of follow-up, 480 new cases of depression were identified, including 156 in men and 324 in women. Individuals who followed the Mediterranean diet most closely had a greater than 30 per cent reduction in the risk of depression than whose who had the lowest Mediterranean diet scores.

Noise-induced hearing loss
Men, especially those who are married, are at an increased risk than women of developing noise-induced hearing loss, says a new study. The study, which analysed the audiometric testing data from 5,290 people between the ages of 20 and 69 years indicates that more than 13 per cent of subjects suffer from NIHL. The strongest association was of gender, where men are 2.5 times more likely to develop NIHL than women.

Pregnancy and asthma medication
Women who shun asthma medications during pregnancy face increased risk of transmitting the condition to their offspring, reveals a new study. The research team from the Universite de Montreal, the Hopital du Sacre-Cœur de Montreal and Sainte-Justine University Hospital Research Centre has revealed that 32.6 per cent of children born to mothers who neglected to treat their asthma during pregnancy developed the respiratory illnessin later life.

“Uncontrolled maternal asthma during pregnancy could trigger a transient yet important reaction in the fetus that affects lung development and could subsequently increase the likelihood of a baby developing asthma in later childhood,” said lead author Dr Lucie Blais.
“We found that failing to control maternal asthma during pregnancy clearly has an impact on asthma in offspring — a consequence that is independent of other contributing factors,” she added.

Air pollution linked to appendicitis
Air pollution may trigger appendicitis in adults, says a new study. The study, conducted by researchers at the University of Calgary, University of Toronto and Health Canada, looked at 5,191 adults admitted to hospital in Calgary, Alberta, Canada. Fifty-two per cent of admissions occurred between April and September, the warmest months of the year in Canada during which people are more likely to be outside.

Using Environment Canada’s air pollution data for Calgary, the researchers determined the levels of ozone, nitrogen dioxide and other air-borne pollutants along with temperature. They found correlations between high levels of ozone and nitrogen dioxide and the incidence of appendicitis between age groups and genders.
