Stress during pregnancy linked with schizophrenia in children

Researchers from the University of Manchester have concluded that women who go through extreme stress during the first three months of pregnancy are more likely to give birth to babies who will have schizophrenia later on in life. The findings were published in the February issue of Archives of General Psychiatry, Science Blog reports. Ali Khashan and his colleagues used data from a staggering 1.38 million Danish births occurring between 1973 and 1995. Women were linked to close family members using a national registry, and the same registry was used to determine if any of these relatives died or received a diagnosis of cancer, heart attack or stroke during each mother’s pregnancy. Their children were followed from the 10th birthday through June 30, 2005 or until they died, moved out of the country, or developed schizophrenia. The risk of schizophrenia and related disorders was approximately 67 percent greater among the offspring of women who were exposed to the death of a relative during the first trimester. However, death of a relative up to six months before or any other time during pregnancy was not related to risk for schizophrenia in the child, nor was exposure to serious illness in a relative. The association between a family death and risk of schizophrenia appeared to be significant only for individuals without a family history (parents, grandparents or siblings) of mental illness. The authors pointed out that chemicals released by the mother’s brain in response to stress may have affect the fetus’ developing brain. These effects may be strongest in early pregnancy, at a time when protective barriers between the mother and fetus are not yet fully constructed. A previous study had suggested that anxiety in general during pregnancy affects child behaviour. Schizophrenia (pronounced 'skit-suh-free-nee-uh') is a medical condition associated with abnormal brain structure and function and is long believed to begin during early stages of brain development. The term itself was coined by Eugen Bleuler in 1908, and comes from the Greek roots schizein ('to split') and phrēn, phren- ('mind').

How to get rid of the Blogger navbar

There's hardly a Blogger user to be found who hasn't been irked by the navbar. True, it’s not entirely useless – it lets you quickly log on to Blogger and provides a quick customization link. But by just being there the navbar brings a generic look to your blog, which is enough to make readers not take it seriously. On top of that, the navbar allows any Blogger user to flag your blog! (Which, assuming you’re one of the good guys, puts you at the mercy of the goodwill of your diverse readership.)Therefore it’s imperative that you hide your Blogger navbar, or at least know how to. In case you’re wondering, the Blogger Terms of Service doesn’t say anything about the navbar, so you’re good to go.Hiding the Blogger navbar1. Sign in to your Blogger account.

Miscellaneous security software (part 1)

This is part 9 in my Optimizing Broadband|Windows|Firefox series and part 1 of my reviews of miscellaneous security software. Covers anti-spyware, anti-adware, registry cleaners, junk file cleaners, and install monitors.The following aren't really reviews, but should provide you with everything you need to know.

Anti-spyware and anti-adware reviews
Most antivirus applications today come with built-in anti-spywares, so unless you're suspicious something is wrong with your PC you don't need to worry. However, it would be a good idea to install a third-party anti-spyware and anti-adware once in a while to make sure everything's under control. The chief anti-spyware and anti-adware brands are Windows Defender (from Microsoft), Ad-Aware 2007 Free (Lavasoft), AVG Anti-Spyware Free Edition (Grisoft) and Spybot S&D (Safer Networking). Note that I haven't mentioned any paid software, such as the popular Spy Sweeper (Webroot Software). It hardly makes any sense to spend m…
