Actos, A Diabetes Drug May Help Prevent Heart Attack

Not only as a diabetes drug that works by addressing the body's insulin resistance, a new study has found that the diabetes drug pioglitazone (Actos)may also help reduce the risk of recurring stroke and heart attack, which are a major cause of disability and death worldwide.

Insulin resistance is known to raise stroke and heart attack risks. Pioglitazone, which helps improve insulin sensitivity, was found to reduce incidence of these cardiovascular events

For the new study published in the New England Journal of Medicine, researchers recruited nearly 4,000 people who were not diagnosed with diabetes but were insulin-resistant for five years to receive either pioglitazone or placebo.

Of those who received the placebo, 11.8 percent had either a stroke or heart attack. These incidences were lower at 9 percent in those who received the drug.

The occurrence of diabetes was also lower in those who took pioglitazone. About 4 percent of those who took the medication developed diabetes while 7 percent of the placebo patients developed the condition.

"We found that pioglitazone, a therapy directed at improving insulin sensitivity, can prevent cardiovascular events among patients who have insulin resistance along with cerebrovascular disease," the researchers conclude in their study. "Administration of pioglitazone in 100 patients similar to those in our trial for about five years could prevent three patients from having a stroke or myocardial infarction."

Scientists have long known that insulin resistance, which happens when the body's cells do not respond normally to insulin, increases risk for stroke and heart attack and the new study shows the benefits associated with using drugs for insulin resistance in preventing these incidences.

"After years of controversy, pioglitazone is now proven to have cardiovascular benefits," says Dr. Silvio Inzucchi, from Yale University. "It's exciting to think that metabolic therapy may now be poised to take its place beside aspirin and cholesterol- and blood pressure-lowering therapies for preventing stroke in non-diabetic patients."


The study also found risks associated with taking the medication. The drug, for instance, was found to increase risk of bone fracture that requires either hospitalization or surgery. Weight gain and edema were also observed in patients who took the drug.

Despite the unwanted effects, the researchers say that the study identified pioglitazone as a new option for preventive health.

Nigerian army Claims the Second Rescue of Chibok Girl

A second schoolgirl that was seized in the Nigerian town of Chibok has been found, the army says. But a spokesman for the Chibok girls' parents has cast doubt on the claims, saying that the girl's name is not on the families' list of those missing. An army spokesman said Serah Luka was among a group of 97 women and children rescued by troops in the north-east. Islamist militant group Boko Haram has abducted thousands of other girls in recent years, rights groups estimate. This comes two days after the rescue of the first Chibok girl, Amina Ali Nkeki. The army has previously given misleading statements about the rescue of the Chibok girls - in its initial statement after Ms Nkeki was found, it used a wrong name. In all, 218 girls remain missing after their abduction by the Boko Haram Islamist group from Chibok secondary school in north-eastern Nigeria in 2014. Ms Nkeki told a Chibok community leader that six of the kidnapped girls had died, but...

Hong Kong Lunar New Year Celebrations Erupt in Violence as Police Clear Food Stalls

Hong Kong's Lunar New Year celebrations have descended into chaos as police leared illegal food stalls set up on a busy junction for Lunar New Year celebrations, leaving dozens injured or arrested. Riot police used batons and pepper spray and fired warning shots into the air early on Tuesday after authorities tried to move illegal street vendors from a district in the city. Protesters hurled bricks at police as scuffles broke out, while other demonstrators set fire to rubbish bins in the streets of Mong Kok, a gritty neighbourhood across the harbour from the heart of the Asian financial centre. A police statement said that three men aged 27 to 35 were arrested for assaulting a police officer and obstructing police, while another three police officers received hospital treatment. Broadcaster RTHK said later that 24 people had been arrested. The scuffles broke out after police moved in to clear "hawkers", or illegal vendors who sell local delicacies, trinkets and ...
