Women's lung cancer risk not tied to childbirths (Reuters)

NEW YORK (Reuters Health) ? A woman's lung cancer risk doesn't appear to be linked to the number of children she has, although some scientists had thought hormonal changes during pregnancy might protect against the disease.

That's according to a new report that sums up 16 previous studies on the topic, which researchers have explored to get a better understanding of lung cancer and possible treatments.

If lung cancer in women were tied to hormones the same way some breast cancers are, for instance, similar drugs might be effective against both diseases, said Jessica K. Paulus, who worked on the analysis.

So far, however, studies haven't agreed on whether or not pregnancies -- and by extension hormones -- play a role in lung cancer.

That was also clear from the new work, said Paulus, of Tufts University in Medford, Massachusetts.

"If you look at the component studies, they are all over the map," she told Reuters Health, adding that she and her colleagues had hoped to be able to explain that variation.

"We came up relatively empty-handed," Paulus said. "It makes it difficult to interpret our findings."

Lung cancer is the leading cause of cancer deaths in the U.S., according to the American Cancer Society.

The disease is rare in younger adults, but becomes more common as people grow old. Overall, the risk of getting lung cancer is about one in 13 for men and one in 16 for women. But these overall numbers include smokers, whose risk is many times higher than that of non-smokers.

"Both active smoking and exposure to second-hand smoking are some of the strongest risk factors for lung cancer," said Paulus. "Quitting smoking and quitting soon is associated with reducing your risk of lung cancer."

Despite the new findings, Paulus added that a link between childbirths and lung cancer still can't be ruled out. She said she hopes a more in-depth analysis of the existing evidence -- including detailed data on each woman -- might help close the issue.

PFT: Vikes hope Peterson back for Week1

Raheem MorrisAP

Raheem Morris? ?Youngry? defense is officially the worst in the league. No group has given up more points.

Tampa has lost nine straight games. They have lost the last four games by an average of 23 points-per-game.

Morris is clearly feeling the heat, and it?s starting to show up in his press conferences. He was asked Monday why he should be retained.

?I will never fire myself,? Morris said via Rick Stroud of the St. Petersburg Times. ?We go out, man, and you don?t go from being a Coach of the Year candidate to being the worst coach in the league to get fired within a year. It?s about us. It?s a little bit of everything.?

My wife happens to be sitting next to me. She doesn?t know a lot of about football, but she read that statement from Morris:

?I?d fire him just for that quote. It?s immature,? she said.

Whether Morris stays or not, he?s going to have to look in the mirror of how he handled his team?s struggles publicly and privately. There has been a lot of excuse-making instead of taking responsibility. His team collapsed when things went wrong, rather than responding to adversity. The Bucs need to examine the underlying reasons for that collapse.

Morris wants to stay the course.

?I believe in my guys. I believe in the system. I believe in the program. I believe in what we do and everybody in this building, so it?s a buying-in factor. Either you buy any or you don?t. And we want to building this thing young and we want to develop a team that goes out and wins ? and wins consistently.?

Bucs ownership has three options. They can fire Morris, bring Morris back as a ?lame duck? coach, or extend Morris? contract.

The young coach has started to publicly make the case for staying by pointing out how young this team is.

?We made a collective agreement to go young when we took over this program,? Morris said. ?That?s something we wanted to do. In order to upgrade in certain positions, sometimes you got to get worse before you get better.?

Facebook agrees to changes for those in Europe

Facebook has agreed to make several changes to its services to improve transparency and better protect the personal data of its millions of users outside of the U.S., following an in-depth audit of its international headquarters that was released Wednesday.

The social media company, based in Palo Alto, California, agreed to changes including asking European users if they wanted to partake in its Facial Recognition, reworking its policies of retaining and deleting private data, and reducing the amount of information collected about people who are not logged into Facebook, the company said in response to the report of the Irish Data Protection Commissioner.

Facebook's international headquarters are based in Dublin, Ireland, a member of the European Union. This means the company is required to comply with European data privacy laws, which are more stringent than those that apply in the United States, particularly regarding how long data can be retained.

"Facebook has committed to either implement, or to consider, other 'best practice' improvements recommended by the data protection commissioner," the company said following the announcement of the report. "Meeting these commitments will require intense work over the next six months."

The company has agreed to present its results in a follow-up to the report in July.

Facebook has been scrutinized for its privacy practices in the U.S., too. In November, the company agreed to submit to government audits of its privacy practices every other year for the next two decades as part of a settlement with the Federal Trade Commission. The FTC's complaint had alleged that the company exposed details about users' lives without getting their consent, as legally required.

It is standard for Ireland's data protection commissioner to audit any high-tech companies in the country to ensure that their practices are in keeping with the European law, and make recommendations to help them to meet those standards, should they fall short.

"It is not the object of the audit, to decide whether there is a breach of law," Billy Hawkes, the data protection commissioner, told reporters. "It is to help an organization achieve full compliance with law, put their compliance into best practice.

Facebook has repeatedly come under fire in Europe for a raft of complaints ranging from accusations that it sells personal data to advertisers ? a charge that the Irish authority said its findings did not uphold ? its Friend Finder application and "archiving" of data that users have deleted.

This is especially the case in German-speaking nations, where laws protecting individual privacy and the use of personal information are even more far-reaching than those covering the European Union, where Facebook has run up against several complaints from local data protection authorities.

A group of Austrian students calling themselves Europe vs. Facebook also took up the crusade, filing a series of 22 complaints directly with the Irish authorities in what they said was an attempt to force Facebook to follow the rule of the law.

"We are thrilled," said Max Schrems, 24, who speaks for the group. "It is far more than what has previously been achieved in Europe. There are a lot of things that they have to change, far more than what they have had to change before."

Barbara Ortutay in New York contributed to this report.

Prawns bring new life to flooded Bangladesh fields (Reuters)

PUTIA VILLAGE, Bangladesh (AlertNet) ? For six months of the year, Bangladeshi rice farmer Raj Mia and his wife suffered as the annual monsoon rains flooded their fields, leaving them unable to feed their five children.

"For months, we had to find some other way to make money, like manual labor or breeding cheap fish like tilapia," said Raj, 48, standing by his submerged farm in the mud-and-thatch village of Putia, 60 km east of Bangladeshi capital, Dhaka.

"It was a struggle as we didn't earn much."

Raj, like millions, lives on the flood plains of Bangladesh, a region increasingly battered by climate change-produced cyclones and rains which inundate swathes of farmland, perpetuating poverty for millions.

But now, Raj has new hope from an unlikely source: prawns.

Last year, he and other farmers in the Comilla district began breeding the crustaceans, along with the usual fish, in their flooded fields, boosting their incomes almost six-fold and learning business skills to help them sell in markets.

"We earned 80,000 taka ($1,038) this year," says Fatuma Begum, Raj's wife. "It's changed our lives ... we have been able to send our children to school."

An initiative introduced by the Center for Community Development Assistance (CCDA), a microfinance charity, has spread across the district. Some 250 families now live off freshwater prawn culture half the year, and cultivate rice when the water levels recede on the same land for the other half.

"By providing people with small loans and necessary training, our project introduces high value fish like prawns to local farmers and helps them use their land more effectively," said CCDA Executive Director M.A. Samad, adding that the pilot scheme is now being replicated by authorities in other flood-prone areas.

"This will develop business entrepreneurs, improve livelihoods and help lift many of these flood-hit communities out of poverty."

FLOOD DEVASTATION

Bangladesh is one of the most flood-prone countries in the world. It is the drainage basin for rivers that start in the snowy Himalayan mountains of India, Tibet, Nepal and Bhutan, including the massive Ganges and Brahmaputra, and criss-crossed by some 250 other rivers.

A few, such as the Meghna, swell to up to 8 km (5 miles) wide during the monsoon season, from June to September.

As a result, most of Bangladesh is a flood plain -- good arable land often at high risk of being submerged.

With 70 percent of the nation's 160 million people dependent on the land, and climate change threatening more extreme weather, it faces an upward struggle to improve food security.

Experts say microfinance, such as the prawn farming scheme funded by the United Nations' International Fund for Agricultural Development (IFAD), may be a key source of help.

"Smallholder farmers are the backbone of the rural economy -- but they are bearing the brunt of climate change... The current speed and intensity of climate change are outpacing their capacity to adapt," said Thomas Rath, IFAD's Bangladesh program manager.

Rath said access to financial services in rural areas allows the poor to manage household cash flows, start new agricultural activities and set up small businesses, resulting in higher earnings and reducing the impact of climate change.

Projects like the one in Comilla bring microfinance to life.

Fishermen cast vast nets from rickety wooden boats in the middle of the lake-like flooded fields surrounding dusty village roads, pulling in a plentiful catch of prawns and other fish. The prawns fetch around 1,500 taka ($19) per kg and are sold domestically.

Villagers point to the visible improvement in their lives which they attribute to the prawn farming, such as the construction of toilets and more children in school.

But the loans, around 50,000 taka ($650) to start such businesses, are not cheap. They carry an interest rate of 26 percent -- up to three times higher than a personal loan from banks, and prompting criticism from social activists.

Lenders like the CCDA argue that high interest rates are justified, citing the costs of making and collecting door-to-door payments in remote rural areas on millions of tiny loans. It is still the best option for rural poor, they add.

Borrowers acknowledge the high rates, but also know their lives are better.

"Now I work too and sell the prawns in the market," said Fatuma, gazing out onto her flooded fields. "We've managed to build a better house as a result of the money we've earned."

US volunteers in North Korea to build homes (AP)

PYONGYANG, North Korea ? A group of Americans is in North Korea to kick off a project to build 50 homes for families working at a tree farm outside Pyongyang.

Six volunteers affiliated with the Fuller Center for Housing arrived Tuesday. Their trip comes at a time of improving relations between the U.S. and North Korea.

The 50-unit project will house the families of workers at a tree nursery in Osan-ri.

Participants with the nonprofit Fuller Center say they'll be working side by side with North Koreans to build the homes.

They're aiming to finish three homes this week, and other volunteers are expected to arrive in coming months to help complete the project.

In Americus, Georgia, Fuller Center President David Snell called the project a "true mission of peace."

The United States and North Korea fought on opposite sides of the Korean War and do not have diplomatic relations. Diplomats from the two countries recently held talks about resuming six-nation nuclear disarmament talks.
