and we re faced with life-threatening infections we often turn to alternative sometimes unproven methods.

We are susceptible to bacterial infection whenever our skin is punctured which happens quite a lot during hospital treatment.

and was in fact worse for diabetic dialysis patients. Getting something like honey to the market as a food product is pretty straightforward

But alternative or oenatural medicines can be put straight to market provided they don t do any harm

A commercial version of oeantibiotic honey Medihoney has actually been evaluated clinically for the treatment of ulcers.

and widely available and while it cannot be used for systemic infections (for pneumonia for instance or bacteremia) it has been used for open wounds.

It can kill many types of bacteria and is thought also to provide a barrier to moisture.

The Lancet paper looked closely at how a naturally-derived honey preparation compares against a clinically-approved antibiotic a drug called Bactroban that s used to kill bacteria found in and around wounds.

The main culprit Staph aureus lives on our skin and can cause infection around catheters used during treatment of dialysis-related infections.

A total of 371 trial participants undergoing dialysis received either standard antibiotic therapy to prevent infection

The study found no significant differences in infection rates or deaths from infection between most people given the antibiotic

or people given honey. But for people with diabetes which is associated often with kidney disease the honey actually increased the risk of infection.

This is important because diabetes is the leading cause of kidney failure so any therapy should work with normal and diabetic kidney dialysis patients.

The reasons for the diabetes-kidney failure link are understood not completely but diabetics often have both high blood glucose levels and high blood pressure both

of which can cause kidney damage. There s also a hormone system called the renin-angiotensin system that regulates blood pressure

and fluid balance involving the kidney which is unbalanced in diabetics. While honey therapy was worse than antibiotics for diabetics the authors found the most important factor for preventing infection in all patients was how well the catheter was inserted and fixed.

There was no placebo control possible in the trial (where no treatment is given) as these infections are sometimes fatal.

We can conclude that honey therapy instead of antibiotics at least does no harm for many dialysis patients but also that it s not good for diabetics.

And because diabetes and kidney disease are linked commonly and 9%of the patients treated with either therapy still died the bottom line is still that we need better therapies for bacterial infection whether natural or man-made.

#How Deadly H7n9 Flu Could Jump from Birds to Mammals Chinese researchers have found new clues to the origins of the deadly H7n9 flu virus

and also found a new flu virus lurking in birds that could potentially infect mammals.

The new research shows that the deadly H7n9 flu virus which emerged in China in March likely originated in migratory birds was passed to domestic ducks

As the researchers studied the H7n9 flu they found a previously unknown virus called H7n7.

In laboratory tests this H7n7 virus infected ferrets which are used often a model for human flu transmission.

Flu viruses are named for their proteins the H in the name comes from hemagglutinin and the N from neuraminidase.

Both the H7n9 virus and the H7h7 virus belong to the H7 family of viruses. 6 Flu Vaccine Myths There are probably other viruses like H7n7 that are circulating in the poultry populations in China said study

researcher Yi Guan of the Joint Influenza Research Centre in Hong kong. China has about 65 percent of the world's domestic ducks

Many flu viruses Guan noted don't cause people any problems. They spread through poultry populations

But H7-type flu viruses persist and oftenâ evolve into new forms. Vincent Racaniello professor of microbiology and immunology at Columbia University in New york said this kind of surveillance study is important in finding new viruses and understanding them better.

Guan said the most surprising thing the team found was just how widespread flu viruses are.

Influenza viruses often change as they are transmitted between individuals and species; as H7n9 made its way from migratory to domestic birds it exchanged genes with other types of flu.

That's what gave it the ability infect people the researchers said. A key development for the virus was altering its proteins so it could bind to the cells in the upper respiratory tracts of chickens.

Many varieties of flu live in the birds'intestines but they aren't spread through the air.

and a 2012 study found these measures reduced the spread of influenza. Racaniello emphasized that

while the number of deaths due to H7n9 may make the virus seem particularly worrisome it's important to remember that not all cases of infection are reported.

The people who died might have other health problems he said. Guan said his team plans to study how H7n9 kills

#It's Time To Worry About the New Chinese Bird flu: Op-Ed Jeff Nesbitâ was the director of public affairs for two prominent federal science agencies

It's time for the world's public health officials to pay very close attention to the new bird flu outbreak in China first detected in March.

To put it bluntly there are now some seriously dangerous developments occurring around the new disease outbreak in China that infectious disease specialists

 the first reported case of the new bird flu strain outside China; the fact that any potential vaccine tests in animals (not humans) may be up to six weeks out;

Bird-flu Update: Possible Cases of Human-to-Human Transmission Investigated The situation remains complex and difficult

When we look at influenza viruses this is an unusually dangerous virus for humans Keiji Fukuda the World health organization's assistant director-general for health security said Wednesday at a briefing.

Chinese officials nd public health officials around the world ad hoped that this potentially virulent and deadly bird flu strain (H7n9) could be contained inside China

days after returning to Taiwan according to Taiwan's Central Epidemic Command Center nd the fact that Chinese officials are publicly saying that at least some of the existing cases may have involved human-to-human transmission this new bird flu strain could spread nd fast.

New Bird flu Virus: 6 Things You Should Know None of this is good. Right now 18 percent of the cases in China have ended in deaths.

While this is still less deadly than the previous avian flu outbreak in China six years ago he H5n1 bird flu virus eventually killed more than 300 people after spreading from China to other countries in 2006 he death rate for this new Chinese bird flu

epidemic is more than triple the mortality rate of tuberculosis in China today. Despite widespread fears among public health officials that the earlier bird flu strain years ago might become a human-to-human pandemic that didn't occur.

Nearly all reported cases of the earlier bird flu strain while deadly seemed to jump from poultry to humans who were handling them or in contact with them.

For this reason despite dozens of outbreaks it was easier to contain the spread. But if this new bird flu strain does in fact become capable of human-to-human transmission

and it takes awhile for a suitable vaccine to be developed then international public health officials are going to start sweating.

One flu-virology expert John Oxford from Queen Mary University told Reuters this week that the emergence of this completely new strain of bird flu infections in humans was very very unsettling.

This new strain is in fact a mixture of three different types of bird flu variants and seems to have been quietly spreading in chickens without anyone knowing about it he said.

Public health officials in general have been worried about bird flu viruses for years. Research several years ago showed that the virus could be transmitted from an expectant mother to a fetus

New Rules on Mutant Bird flu Research Stir Debate What's more it could reignite fears about the possibility of deadly global pandemics.

A decade ago several well-known virologists and public-health experts warned in published papers that the world was at risk for pandemics that could kill tens of millions of people or even more without adequate infectious disease monitoring and medical research.

The 2006 Chinese bird flu outbreak came on the heels of those global pandemic warnings. The good news is that China is more transparent about disease epidemics now than it was a decade ago

and that the number of reported cases with the new bird-flu strain has jumped not dramatically so far.

And China learned a lot about how to limit the spread of bird flu after the last outbreaks simply by closing down poultry markets that appear to be likely starting points.

But the fact that the new H7n9 strain has moved now outside China nd that Chinese officials are taking a close look at human-to-human transmission possibilities hould send up more than a few red flags.

Just because the previous bird flu outbreak in China didn't spread quickly and prove as deadly as some had feared does not mean that this new outbreak will follow a similar course.

If the suspicions of human-to-human transmission potential is confirmed that alone makes the threat of a pandemic (as opposed to a series of local outbreaks that can be contained with efforts to close down poultry markets or the sale of infected birds) more likely.

In the case of a pandemic a vaccine would need to be developed and distributed quickly.

The price tag for treatment is enough to give you a heart attack AHA predicts that over the next 20 years the cost of cardiovascular medical care will triple from $273 billion in 2010 to $818 billion in 2030.

The good news is there is a relatively straightforward way Americans can avoid heart-related diseases prevent more than 127000 deaths a year

These individuals are the adult children of the original participants in the Framingham Heart Study a long-running Massachusetts-based study designed to pinpoint the factors linked to the development of heart attack and stroke.

and women for 12 years the researchers found that 43 hip fractures had occurred. Because the number of hip fractures in the group was so small the researchers were unable to draw firm conclusions about dairy consumption

and hip fracture risk from their data and they suggest more research is needed. However the findings did show that a higher intake of cream was associated with lower bone mineral density in the hip but not in the spine.

Foods in this group included ice cream sour cream cream cheese and cream. Â Cream is definitely different from the rest of the dairy products said lead author Shivani Sahni an assistant scientist at the institute.
