This is where a third suicide bomber blew himself up targeting a Police Checkpoint in western baghdad. Theyre still washing down the streets. This is a residentialne neighborhood, and there is a sense that nowhere in the capital is safe. Especially as this is a sunni neighborhood, some of whom are loyal to isis. It made no difference to residents here that the intended target appears to have been Iraq Security forces. Police officer mohammed amids, told us, i saw bodies on the ground. And i tried to help, but they all died. [ gunfire ] iraqi forces have been fightingis isis for more than two yearsca with help from american air strikes. And while isis has been forced to retreat in recent months, todays events show the militants can still strike with lethal force in the heart of the capital. Weve seen in the past, scott, that when isis suffers significant losses on the battlefield, they launchr at spectacular attacks in baghdad. Its not the only reason the city is on edge.

It suggested a possible link between high levels of folic acid in pregnant women and andr increased risk of their children developing an autism spectrum disorder. Well, our dr. Jon lapook has been looking into this and is with us now with a dose of reality. Gn jon, pregnant women are told to take folic acid. Reporter right. And that stays exactly the same. Theres no doubt that women who have too little intake of folic acid during pregnancy have an increased risk of having kids with severe neurological problems, birth defects. So that recommendation from the government, which is to take 400 to 800 micrograms of folic acid a day during pregnancy stays exactly the same. Nobody is questioning that. Pelley so what do you make of this study . Reporter well, this study, normally we would not cover a story that was this preliminary. Its an abstract, meaning it hasnt yet been even submitted for publication to a journal. It has not been reviewed yet by the scientific community. There are some numbers in there that give me pause. E for example, the rate of autism that they report is about five times what the c. D. C. Reports. And that makes me wonder, are they overdiagnosing autism . That said, what it showed was that women who have very high levels of folic acid, which is folate, or b12 soon after delivery had kids who went on top develop autism at a higher rate than normal. T now, this does not mean thath taking too much b12 or folate causes autism. This is an association. Th there needs to be a lot more study. The bottom line here is the recommendation stays exactly the same. We do not want women toad misinterpret this headline. They should still be takingti folic acid supplementation. During pregnancy. Pelley so despite the headlines weve seen today, thisst study is extremely preliminary and doesnt change the advice take folic acid when pregnant . Reporter yes. Re t and, of course, always check with your doctor during t pregnancy or any other time when youre taking any kind of supplementation or medication. Pelley jon lapook with the straight story.
