Smoking in pregnancy risks psychotic children

Mothers who smoke during pregnancy put their children at greater risk of developing psychotic symptoms as teenagers, British scientists said on Thursday.

Researchers from four British universities studied 6,356 12-year-olds and interviewed them for psychotic-like symptoms such as hallucinations or delusions. Around 19 percent had mothers who smoked during pregnancy.

Just over 11 percent, or 734 of the total group, had suspected or definite symptoms of psychosis.

Many previous studies have shown cigarettes can harm the fetuses of mothers who smoke while pregnant. The risks include causing babies to be born smaller and increasing the risk of sudden infant death syndrome or heart defects.

Stanley Zammit, a psychiatrist at Cardiff University’s School of Medicine who led the study, said the more the mothers smoked, the more likely their children were to have psychotic symptoms.

“We can estimate that about 20 percent of adolescents in this cohort would not have developed psychotic symptoms if their mothers had not smoked,” he said.

Despite countless studies flagging up the risks to babies, it is estimated that between 15 and 20 percent of women in Britain smoke during pregnancy.

The researchers also found drinking during pregnancy was associated with increased psychotic symptoms, but only in children whose mothers had drunk more than 21 units of alcohol a week in early pregnancy.

The reasons for the link between maternal smoking and psychotic symptoms are not clear, but Zammit and colleagues suggested that exposure to tobacco in the womb might affect a child’s impulsivity, attention or cognition.

They said more research was needed to investigate how exposure to tobacco in the womb affected children’s brains.

Only a few mothers in the study, which was published in the British Journal of Psychiatry, said they had smoked cannabis during pregnancy, and this was not found to have any significant link with psychotic symptoms.

Inhalers may raise risk of asthma in some children

Inhalers may raise risk of asthma in some children

Common asthma reliever drugs taken by millions of children around the world may increase the risk of asthma attacks in some patients with a particular genetic make-up, British scientists said on Tuesday.

The researchers found that salbutamol, a popular blue inhaler medicine also known as Ventolin, as well as salmeterol, an ingredient in GlaxoSmithKline’s Advair, are less effective in children with a specific gene variant and may in some cases make their asthma worse.

The scientists said their findings suggest that carrying out genetic tests on children before treatment could be a more cost-effective way of treating them.

“This is a global question that needs to be addressed,” said Somnath Mukhopadhyay of Brighton and Sussex Medical School.

Salbutamol is called albuterol in the United States and is very widely used, the researchers told a news conference.

U.S. drug regulators have cautioned in the past that asthma drugs like Advair and Serevent, also made by Glaxo, may actually increase asthma risk in some patients. Glaxo said in a statement it had carried out its own studies with Advair and Serevent and found no genetic variation response differences, although the 500 patients in its study were older than 12.

“Albuterol is one of the commonest drugs right across the world. It is used in the United States, in Africa, India…” said Mukhopadhyay. “It’s cheap, it’s popular, and it’s good stuff — when it works.”

Asthma affects more than 300 million people worldwide and is the most common children’s chronic illness. Symptoms include wheezing, shortness of breath, coughing and chest tightness.

How broccoli can protect your arteries

How broccoli can protect your arteries

It’s long been thought that broccoli is good for your heart, and now British scientists think they know why.

Researchers at Imperial College London have found evidence a chemical in broccoli and other green leafy vegetables could boost a natural defense mechanism that protects arteries from the clogging that can cause heart attacks.

In a study funded by the British Heart Foundation charity and conducted on mice, the researchers found that sulforaphane — a compound occurring naturally in broccoli and other brassicas — could “switch on” a protective protein which is inactive in parts of the arteries vulnerable to clogging.

“We know that vegetables are clearly good for you, but surprisingly the molecular mechanisms of why they are good for you have remained unknown for many years,” said Paul Evans of the National Heart and Lung Institute at Imperial College.

“This study provides a possible explanation for how green vegetable consumption can promote a healthy heart.”

Scientists already know that arteries don’t clog up in a uniform way, but that there are bends and branches of blood vessels — where blood flow is disrupted or slower — which are much more prone to the build-up of fatty plaques that cause heart disease.

Evans said his research found that in the more vulnerable areas, a normally protective protein known as Nrf2 is inactive.

“What our study showed was that sulforaphane can protect those regions by switching on the Nrf2,” he said.

The research, reported in the journal Arteriosclerosis Thrombosis and Vascular Biology, was conducted using purified sulforaphane, not broccoli. Researchers said the next step was to test the effect of the chemical as it is found in vegetables.

We now need to go and test this with broccoli smoothies, as it were, and compare that with the effect of purified sulforaphane,” Evans said, adding that if the vegetable form proved less effective, there could be an argument for taking sulforaphane in pill form.
