Exposed by Cigarette Smoke When Pregnant Can Make Sudden Infant Death

Mothers who smoke or are often exposed to cigarette smoke exposure during pregnancy can cause the baby's blood pressure becomes abnormal. Abnormal blood pressure cause of sudden infant death.

The team of researchers from Sweden's Karolinksa Institute found exposure to cigarette smoke during pregnancy can cause the baby's blood pressure becomes abnormal even until the child grew up.

Abnormal blood pressure makes the heart to pump faster and harder. Studies have shown damage to the circulation may be a risk factor in sudden infant death syndrome (SIDS).

Dr Gary Cohen and his team analyzed 36 newborns, 17 of them born to mothers who smoked during pregnancy. When babies are frequently exposed to smoke are examined, suggesting an abnormality in heart rate and blood pressure. This situation worsened during the first year of life.

"Usually when someone is standing heart rate increases and blood vessels tighten. In infants of mothers who smoke, the problem occurs continuously from birth until the first 1 year and get worse from time to time," said Dr. Cohen, as quoted by BBC News , Wednesday (27/1/2010).

Dr. Cohen added for some time been aware of the cardiovascular effects in cases of sudden infant death. And this probably explains why this could happen. Exposed to smoke early in life to make blood pressure control mechanisms disrupted.

"His influence not only on your breathing babies, but also the control of blood pressure and heart rate," says Dr. Cohen.

"The results of this study is reasonable. Sudden infant deaths could be avoided by not let anyone smoke in the same room with the baby. In addition a third of sudden infant deaths could be avoided if the mother did not smoke during pregnancy," said Professor George Haycock, advisor of Foundation for the Study of Infant Deaths

Women Lose 90 Percent Egg When Age 30

London, Why do women aged 30 years and over is very difficult to get pregnant? Researchers have found the answer. Women lose 90 percent of eggs when entering the age of 30 years.

Women had been taking 90 percent of her eggs when she was 30 years old. Although still able to produce eggs at the age of 30 to 40 of the year, but the egg reserves continue to shrink rapidly.

Researchers said the body of choosing the best egg from its reserves. While female egg quality will get worse as you get older and the increasing difficulty in having a healthy baby.

Research carried out the University of St Andrews and Edinburgh University are the first of the decline in the number of ovarian reserve is so fast and hard seed fertilization menopause.

The results showed an average of 300 thousand women have eggs, but this number will decline rapidly than previously thought. At the age of only 30 years old female egg reserves 12 percent and 3 percent at age 40 years.

Dr Hamish Wallace in his writing the research tells us that this has been done to show the prospects of women's fertility rates.

"Our research shows that 95 percent of women at the age of 30 years had only a 12 percent maximum of ovarian reserve and at the age of 40 years, only three percent of the remaining," he said as quoted by the Telegraph, Thursday (28/1/2010).

Researchers say many women who think wrong by assuming they can still produce eggs and keep the level of fertility. However, this study showed a decrease in significant egg quickly.

Research conducted with 325 women using the data in the UK, U.S. and Europe of all ages to assess the potential of the egg cell reserves. Researchers then use these data to graph the average reduction potential of ovarian reserve throughout the life of women.

Dr. Wallace, who practiced at the Royal Edinburgh Hospital also said this research could help predict early menopausal women and egg freezing of ovarian cancer patients.

A study published in the journal Public Library of Science One also showed a big difference female egg cell. Some of the women there who have the egg up to 2 million eggs, but there also has at least 35,000 eggs. But the average woman has 300 thousand eggs.

This research is a warning to women not to late to plan a pregnancy. Because the fertility of women after the age of 30 years will fall drastically
