Summary:
New research shows that pregnant women who smoke as well as having asthma are greatly increasing the risk of complications for themselves and their unborn children.

New research from the University of Adelaide has shown for the first time that pregnant women who smoke as well as having asthma are greatly increasing the risk of complications for themselves and their unborn children.

In the first study of its kind in the world, researchers from the University's Robinson Institute compared data from more than 170,000 Australian women over 10 years.

The results have been published online ahead of print in the European Respiratory Journal.

Lead author Dr Nicolette Hodyl says: "We know that being pregnant and having asthma poses risks to both the mother and the baby. We know that smoking poses risks to both the mother and the baby. But now we also know that the combination of these conditions represents a very dangerous situation.

"Asthma and smoking are separately linked during pregnancy to increased risk of bleeding from the birth canal before labor, urinary tract infections, premature rupture of membranes, low birth weight and preterm birth (less than 37 weeks of pregnancy).

"The combination of asthma and smoking greatly increases the risk of these complications during pregnancy."

Dr Hodyl says 5.8% of pregnant women who were not asthmatic and non-smokers experienced a preterm birth. "For asthmatic women, the preterm birth rate increased to 6.5%. Among smoking women, 9.4% experienced preterm birth. And for asthmatic women who also smoked, the rate of preterm birth jumped to 12.7%, which is more than double the normal rate.

"This is an alarming statistic. We hope that pregnant women begin to understand the seriousness of this situation to their health and the health of their child," she says.

Dr Hodyl says the research also uncovered another worrying statistic: about a quarter of pregnant women with asthma are smokers.

"While the rates of smoking have been decreasing in recent years, it is very concerning to us that many pregnant women with asthma are also smoking," she says.

"Quitting smoking during pregnancy is very difficult, and therefore pregnant women need as much support as possible from family, friends and health professionals. Our results show that even a reduction in the number of cigarettes women smoke per day can lead to some improvement to the risks to their child. However, the potential for poor health outcomes for both the mother and child should not be underestimated."

This research has been funded by the National Health and Medical Research Council (NHMRC).

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
