BPA ‘reduces effect of cancer drugs’

BPA interferes with chemotherapy, scientists sayAnother health risk connected to bisphenol A (BPA) has been uncovered and described in the most recent issue of Environmental Health Perspectives.

According to researchers from the University of Cincinnati, BPA can reduce the effectiveness of chemotherapy treatments.

Dr. Nira Ben-Jonathan and colleagues exposed human breast cancer cells to BPA at levels that reflect those typically found in a person’s bloodstream.

They discovered that the chemical helped protect the cancer cells from dying when confronted by chemotherapy medications.

BPA has been in the spotlight in recent months due to a growing body of research that has linked it to health problems ranging from problems with sexual development in babies to heart problems in adults.

Canada recently became the first country to ban the chemical from being used in the manufacture of baby bottles.

According to the University of Cincinnati researchers, understanding BPA’s health risks helps increase their understanding of chemotherapy resistance.

"These data provide considerable support to the accumulating evidence that BPA is hazardous to human health," the authors wrote.

Scientists modify tomato to fight cancer

Scientists have developed a purple cancer-fighting tomatoScience has taken its efforts at developing genetically modified foods one step further, creating a type of tomato that is hoped to help combat cancer.

The purple tomatoes were created by British researchers by incorporating genes from the snapdragon flower, a plant that contains an antioxidant called anthocyanin.

Anthocyanin is already naturally found in blackberries, cranberries and chokeberries, but scientists sought a way to make it easier to incorporate into the diet.

After developing the tomato, the team fed it to rats that had been engineered to develop cancer and compared the effects to mice that ate a normal diet.

The animals that ate purple tomatoes lived around 182 days on average, compared with the 142-day lifespan of the control group.

Although the health benefits of the new tomato may be welcomed by some, others have raised concerns about the safety of eating so-called Frankenfoods created in a laboratory rather than those which grow naturally without the intervention of science.

Last month, the FDA released guidelines on how it plans to regulate genetically modified meats. Some experts were surprised that these foods would not necessarily have to be labeled as such.

Arizona to vote on freedom of choice in healthcare

Healthcare choice is on Arizona's ballotThe freedom of Arizonans to make decisions about their own healthcare without consulting with the state is at stake on the November ballot.

In an editorial written for the Washington Post, George Will describes the situation as a decision that would either "arrest or accelerate the nation’s slide into statism."

Proposition 101 is a measure that aims to add language to Arizona’s constitution that prohibits any law from being passed that would interfere with residents’ right to choose, pay for or opt out of any healthcare system or plan.

According to Will, this measure would guarantee more flexibility for Arizonans and protect their civil liberties from third-party infringement.

"Proposition 101 would protect Arizonans not only against abridgements of their liberties by their state government, but also perhaps against comparable actions by the federal government," Will writes.

He explains that the proposition recognizes the valuable role of the market in being able to allocate resources better than the state and federal government.

Writing in favor of Proposition 101, Phoenix doctor Anthony K. Hedley raises concerns that state-controlled healthcare could mean that Americans have to wait longer to receive important life-saving procedures.

Did the bailout increase market volatility?

The stock market was unsettled after the bailoutPresident Bush and Congress may have attempted to quell the volatility of the stock market by approving the $700 billion bank bailout, but some experts are suggesting the move has had the opposite effect.

A report on Newsmax raises concerns about how the rescue package and related measures have affected issues of value and risk.

"Now that deposits are guaranteed, basically I as an investor have no incentive to hold equities, so I sell them and put my money in bank deposits," financial author Marc Faber explained to CNBC, according to the news provider.

He claimed that government interventions have made it "impossible to forecast market movements."

And Chris Whalen of Institutional Risk Analytics suggested in a recent newsletter that the bailout has led to a situation in which price and value are no longer linked and investors have lost confidence.

"No wonder the entire stock market is having an extended nervous breakdown," he added.

Meanwhile, ABC News reports that despite the current financial uncertainty on Wall Street and the bailout, many CEOs and senior-level executives will still receive higher-than-expected bonuses this year.

Is gold still a safe investment?

Should you still invest in gold?Gold is traditionally viewed as a safe investment in troubled economic times. However, the price has been falling lately – a trend which has left many experts confused.

This behavior suggests that the credit crunch may be forcing investors’ hands. Mark Hansen of commodities research firm CPM Group told Fox News that people have been making a "mad dash for cash," which has included selling their more valuable assets such as gold.

In a research report released Thursday, the World Gold Council agreed with this sentiment, explaining that funds have been forced to sell precious metals to meet margin calls.

"The fact that gold did not head higher during the current leg of the crisis seems to reflect a combination of the rise in the dollar, deleveraging of commodity positions, sales to meet margin calls and the unwinding of the long gold, short dollar trade," the report states.

Meanwhile, some experts have argued that it is actually a good time to buy gold, because it is a good investment during times of inflation.

Gold Stock Analyst newsletter’s John Doody told the news provider that the recent bank bailout will help prevent deflation and create a good environment for gold investment.

The commodity recently fell to below $700 for the first time in more than a year.

Study: Unsuspecting patients prescribed placebos

Is your doctor giving a real drug or a placebo?The majority of American doctors responding to a new survey said they see no ethical problem with the practice of prescribing placebos to patients without their knowledge.

In this study, published in the British Medical Journal, a placebo is defined as a treatment not specifically aimed at helping a particular condition.

Around half of the internists and rheumatologists surveyed said that they have prescribed placebos several times a month. Only 5 percent of respondents said they specifically told their patients it was a placebo.

Painkillers, vitamins, antibiotics, sedatives, saline injections and sugar pills were the most common placebos prescribed – in that order.

"It’s a disturbing finding. There is an element of deception here which is contrary to the principle of informed consent," co-author Franklin G. Miller of the U.S. National Institutes of Health told the Associated Press.

The authors suggest that doctors may reason that prescribing a placebo – which may potentially provide benefits – is preferable to not doing anything. These drugs also help raise a patient’s expectations for improvement, also known as "the placebo effect."

Placebos are often used in medical trials so that researchers can compare their effects with those of active medications.

Greenspan admits surprise, dismay at market crisis

Greenspan said he was shocked by the credit crisisFormer chairman of the Federal Reserve Alan Greenspan told Congress on Thursday that he was shocked that self-regulation in the financial markets had not functioned the way he anticipated.

At one time, Greenspan – who left the Fed in 2006 after running it for nearly 20 years – was praised for enacting policies that helped stoke the property boom seen earlier this decade.

However, more recently some people have been laying part of the blame for the credit crisis on the chairman’s opposition to regulating the financial markets.

"I made a mistake in presuming that the self-interests of organizations, specifically banks and others, were such as that they were best capable of protecting their own shareholders and their equity in the firms," Greenspan told the House Committee of Government Oversight and Reform.

However, he explained that his decisions not to regulate risky practices such as credit default swaps was based on a philosophy that had previously worked "exceptionally well."

Other financial leaders testifying before Congress included Christopher Cox, chairman of the Securities and Exchange Commission.

Chertoff defends no-fly list

The no-fly list has often been controversialDirector of Homeland Security Michael Chertoff has challenged claims made by civil liberties groups about the number of people not allowed to fly on U.S. airlines.

Instead of the figure of 1 million which has been quoted by the American Civil Liberties Union, the actual number barred from flying totals only 2,500, with 90 percent of these non-U.S. citizens, he said.

In addition, there are around 16,000 people whose names are on a selectee list, which means they may be inspected but not prohibited from boarding a plane.

However, some have raised concerns about the incidents of mistaken identity, in which an innocent member of the public shares a name or other identification with someone on the list.

Some names may even be on the list as the result of an error. Earlier this year, a court of appeals in San Francisco ruled that passengers can bring cases regarding their status on the no-fly list to a judge and jury for consideration.

It made its decision after a Malaysian student at Stanford University was detained and handcuffed at an airport in 2005, the San Francisco Chronicle reports.

Dim forecast for U.S. recovery

The economy may not pick up until mid-2009Investors who have been hoping that the U.S. economy will be given a clean bill of health in the near future may want to think again.

New predictions from the International Monetary Fund provide a gloomy picture for the next six months, suggesting that most countries in the western hemisphere will face near-zero or negative growth until mid-2009.

And, once the U.S. does begin to get back on its feet, the IMF said that recovery will happen more slowly than in previous downturns because of the "exceptional nature of the asset price adjustments taking place."

Other countries in the region are also set to face challenges, the group predicted.

"The outlook points to a major downturn for the global economy, with growth falling to its slowest pace since the 2001-02 recession," the report states.

However, the IMF suggested that the coordinated efforts taken by governments around the globe would eventually lead to a successful recovery for the global economy.

Meanwhile, in related news, CNN Money reported on Wednesday that although there some signs of a credit thaw have been observed, investors continue to behave warily due to warnings about a long recession.

Does anesthesia cause developmental problems?

Questions about anesthesia and behavioral problemsParents may be careful to protect their children from a number of threats to their health, including toxic chemicals and potentially harmful medications.

Now, new research raises questions about the effect of general anesthesia on a child’s developing brain.

Findings reported at the American Society of Anesthesiologists annual meeting reveal that children who were exposed to anesthesia could double their risk of being diagnosed with a behavior or developmental disorder.

Scientists analyzed data from 625 children who had been given anesthesia for a hernia operation and compared it with a sample of 5,000 kids who had not had anesthesia. All participants were covered by the New York State Medicaid program.

They found that 4.8 of the children exposed to anesthesia had later been diagnosed with a developmental or behavioral disorder, compared with 1.5 percent of the control group.

Researcher Dr. Lena Sun told Reuters Health that although the results are provocative, more investigation needs to be done.

"This study basically suggests that we really need to do a more rigorous study to look at this question," she said.

Around 2 million children in the U.S. have been diagnosed with the behavioral problem ADHD, according to the National Institute of Medical Health.

Spending on Medicaid could outpace economic growth

Medicaid spending is set to riseThe amount of money spent on Medicaid could place significant stress on federal and state budgets over the next decade, according to forecasts from the U.S. Department and Health and Human Services.

In fact, spending is expected to rise by an average of 7.9 percent each year over the next 10 years, a rate of growth which is larger than that of the overall economy, the report indicates.

Medicaid is a joint state and federal program that provides insurance for low-income households. It cost approximately $333.2 billion to fund in 2007, with the federal government paying 57 percent of that cost.

HHS predicts that the total cost could reach $647 billion by 2017, with enrollment in the program expected to hit 55.1 million by that year.

"This report should serve as an urgent reminder that the current path of Medicaid spending is unsustainable for both federal and state governments," commented HHS secretary Mike Leavitt.

He urged action to make sure the program remains "fiscally sound."

Last month, a Kaiser Family Foundation and Health Research & Education Trust report found that U.S. health insurance premiums rose by an average of 5 percent last year.

Ron Paul: Government should leave the economy alone

Paul is calling for a significant tax cutThe U.S. government is mistaken if it thinks that it can help the American people by interfering with the free market, according to Texas Representative Ron Paul.

He told CNN’s American Morning program that the bailout will lead to inflation and will end up doing "no good whatsoever" for the country’s economic situation.

In addition, he criticized the idea that creating new money and encouraging spending provide the keys to boosting the economy.

Paul characterized these measures as typifying the "arrogant" belief of politicians and bureaucrats that they can regulate the free market.

Instead, the congressman from Texas called for a "drastic" tax cut that would allow Americans to "keep the money they earn."

When questioned about the future of the country, Paul replied that he finds weaknesses in the economic policies of both John McCain and Barack Obama.

However, when asked to differentiate, he said that the Republican’s healthcare plan offers "a better approach" but that the Democrat’s ideas about withdrawing from Iraq will save the U.S. billions of dollars.

Paul’s comments come as chairman of the Federal Reserve Ben Bernanke has suggested that another economic stimulus package is needed to help heal the ailing economy.

BPA baby bottles banned in Canada

In Canada, BPA is not permitted in baby bottlesThe U.S. Food and Drug Administration may have decided that the chemical bisphenol A (BPA) is safe, but the Canadian government has made it clear it thinks otherwise.

Canada has become the first country in the world to take action against BPA in baby bottles.

The chemical – which is also used in plastic packaging – has been linked to a number of health problems in various studies, but some experts do not find the evidence to be strong enough to support a ban.

For example, in the U.S., the FDA has said that BPA is safe for human use. Earlier this year, spokesperson Laura Tarantino said the FDA was not "recommending any change in habits" in regard to the chemical.

After declaring BPA a toxic chemical on Saturday, Canada said it is working on draft regulations to limit its importation and sale.

Some U.S. states have said they are considering similar bans, with surgeon generals from Delaware, Connecticut and New Jersey calling on the government to act to protect children’s health.

Bernanke calls for further stimulus

The Fed is seeking a new stimulus packageIt was several months ago that President Bush signed a $170 billion stimulus package that he said could help prevent the U.S. from slipping into recession – now, there is talk of introducing another, similar measure.

Speaking before Congress, Ben Bernanke, chairman of the Federal Reserve, suggested that a second government stimulus package could provide a boost to the economy, as consumers cut back on spending.

September retail figures fell by 1.2 percent, which caused stocks to plummet and many financial experts to suggest that the country will definitely enter a recession period.

"With the economy likely to be weak for several quarters and with some risk of a protracted slowdown, consideration of a fiscal package by the Congress at this juncture seems appropriate," Bernanke said, explaining the reasoning behind his suggestion to the House Budget Committee.

He added that any plan should be designed so that it would "limit longer-term effects" on the government’s budget deficit.

Congressional Democrats have been calling for an economic stimulus package for weeks, but have not yet received White House support for the plan.ADNFCR-1961-ID-18836593-ADNFCR

Pittsburgh GPS case prompts privacy concerns

Does GPS surveillance violate privacy? A court case that is currently in the federal courts in Pittsburgh could help set a precedent for how law enforcement officials handle global positioning system data.

The issue centers on whether or not police officers should be required to demonstrate probable cause and obtain search warrants before they track suspects using GPS, the Pittsburgh Tribune-Review reports.

Federal prosecutors and law enforcement officials are seeking permission to obtain information on a suspect’s location using data stored by their cell phone – either in real time or via historic records.

They say that electronic surveillance is less expensive and more effective than following someone in a vehicle.

However, some privacy advocates have raised concerns about the possibility that this technology violates the Fourth Amendment to the U.S. Constitution, which protects against unreasonable searches and seizures.

Some of the legal questions about the use of GPS concern whether or not a person has a reasonable expectation of privacy when their vehicle is driving on a public road.

"The government and police say they are trying to keep people safe, but our rights do come into question. It’s a balancing act," civil rights attorney Sam Cordes told the news provider.

Developed by the U.S. Department of Defense, GPS uses satellites and monitoring stations to provide 3D location information, along with the time.

Social security boost for retirees

Social security is rising by 5.8%Retirees who have been fretting over the state of the stock market and their nest egg have a bit of good news to look forward to – social security benefits are rising by 5.8 percent in 2009.

According to the Social Security Administration, this increase – the largest since 1982 – will mean an average of $63 extra in a retiree’s monthly check.

This year’s jump is a marked departure from the cost of living increases of the past decade, which are tied to inflation. However, recent rises in costs such as food and fuel seem to have pushed the decision.

However, some suggest that despite the increase many seniors will still struggle to maintain their standard of living – or even make ends meet.

"Right now many senior citizens are feeling depressed because things seem out of control," California State economics professor Sung Won Sohn told the Associated Press.

If anything, many people are feeling uncertain about their financial future. The Congressional Budget Office recently estimated that Americans lost a total of $2 trillion from their retirement accounts over the past 15 months, due to fluctuations in the stock market.

New state laws aim to protect customer privacy

Businesses in some states will be required to encrypt dataA new law that took effect in Nevada this month aims to help protect data gathered by businesses about their customers, the Wall Street Journal reports.

The legislation states that companies are required to encrypt any personal information, including names and credit card details, that is transmitted electronically.

Firms may help protect themselves and their customers by purchasing email encryption software. Those that flout the law would be liable for unlimited civil penalties.

Other states, including Michigan and Washington, are mulling similar laws. Meanwhile, from January, Massachusetts businesses will be obligated to encrypt sensitive data about residents that is stored on portable devices, such as laptops.

Privacy lawyers in Massachusetts told the news provider that the legislation potentially paves the way for people to file civil lawsuits against firms in the case of a data breach.

In Nevada, it has already been established that firms complying with the law that suffer a data breach would have caps placed on the amount of damages they are forced to pay in a suit.

Some large-scale data breaches have made the headlines over the past couple of years, including an incident in which the credit and debit card details of 45.6 million customers of retailer TJX were put at risk.

Buffett promotes buying U.S. stocks

Warren Buffett is greedy when others are fearfulInvestor Warren Buffett, one of the richest men in the world, has announced that he is buying American stocks.

A bear market provides a perfect opportunity to purchase stocks at a low price, the billionaire suggested in an opinion column in the New York Times.

The Berkshire Hathaway CEO described how he had moved his money from government bonds to U.S. stocks in an attempt to take advantage of market conditions.

He repeated his oft-quoted advice to investors: "Be fearful when others are greedy and be greedy when others are fearful."

Buffett explained that although we are in the midst of a frightening economic period, including rising unemployment and falling business activity, the situation will take a turn for the better.

"What is likely … is that the market will move higher, perhaps substantially so, well before either sentiment or the economy turns up," he wrote.

Savvy investors will not let this opportunity pass them by, he advised.

Buffett ranked number one on Forbes magazine’s 2008 World Billionaires list, with an estimated net worth of $62 billion.

Hospital admits tools not properly sterilized

Around 160 patients could be at risk of a staph infectionApproximately 160 patients may be at risk of developing a staph infection, following a North Carolina hospital’s admission that it had neglected to sterilize surgical instruments.

Although the tools were cleaned, disinfected, decontaminated and packaged, they were not sterilized, the Fayetteville Observer reports.

Medical officials say that the risk of infection is slight, as the instruments had already undergone all of the other steps of the cleaning process.

However, some patients who have been affected by the scare told the news provider they were unsettled by the news.

One woman who did not want to give her name said, "You are so vulnerable when you’re a surgery patient. You’re at their mercy. You have to believe that they are going to take good care of you."

Dr. Chuck Chima, physician advisor to infection control, said that the patients were at risk of a regular staph infection, but not the antibiotic-resistant MRSA.

According to MedicineNet.com, there are more than 30 different types of staph bacteria that can cause infections in humans, with the most common being staphylococcus aureus.

Civil liberties concerns about bank fingerprinting

Some people object to bank fingerprintingEach year, millions of foreign visitors to the U.S. are fingerprinted at the airport – but did you know that some banks may also require prints from American citizens?

Bank of America customer Pauline Pavlis told the Press of Atlantic City about her experience trying to cash a check at one of the bank’s branches.

Because she is not a customer, she was asked to give a thumbprint to prove her identity, a practice which Pavlis questioned.

"I feel like it’s infringing on my personal liberties. You hear all the time about misuse of personal information," she told the news provider.

Fingerprinting is a common requirement for noncustomers at larger banks, the article states. Five years ago, one of these people sued Bank of America because it would not cash his check without a print and a Maryland court of appeals sided with the bank.

Timothy Doherty of the New Jersey Bankers Association, said that banks have a right to give preferential treatment to customers and prevent identity fraud.

He added that "the issue of protecting identities outweighs the issue of people concerned about giving thumbprints."

The government began fingerprinting foreign visitors to the U.S. in 2004.

Experts uncertain about effects of drugs in drinking water

How do pharmaceuticals in drinking water affect our health?Questions about the effects of trace amounts of pharmaceuticals that are found in Americans’ drinking water continue to cause concern among both scientists and members of the public.

An ABC News report reveals that while some scientists claim the concentration of prescription medications in tap water is so low that it poses no risk, others are deeply concerned about the long-term effects of exposure.

"The concern is we don’t know what these chemicals do in the body over a lifetime of exposure," Dr. Brian Buckley, an environmental scientist at Rutgers University, told the news provider.

He acknowledged that the amount of contamination is very slight, but said that he would rather "be safe than sorry" in regard to consuming pharmaceuticals through the water supply.

Additionally, Buckley raised concerns about the possibility of "drug-drug interaction," which may not be apparent until a person has consumed tap water over a period of several years.

Earlier this year, an Associated Press investigation uncovered levels of pharmaceuticals present in the drinking water of 24 major metropolitan areas across the country.
