Spanish Researchers Find A New Analgesic More Potent Than Morphin

Researchers from the "Consejo Superior de Investigaciones Científicas" (CSIC) have found a synthetic derivative of morphine which, when administered in rats, shows an analgesic effect one hundred times more powerful and twice as durable than morphine, as well as having fewer side effects.

The finding, published in the Journal of Medicinal Chemistry, opens the door to design new and better analgesics for the treatment of chronic and severe pain.

"Although in the past 40 years many new compounds with analgesic capacity have been discovered, there has been no significant progress for the treatment of chronic pain," says researcher Gregory Valencia. "This is the first time that a sugar (mannoside) derivative of morphine shows more analgesic capacity than the original drug".

WHO Fears Genes Exchange Between H1N1 and H5N1 Avian Flu

As the Influenza A/H1N1 virus continue to spread worldwide at a fast pace, WHO experts express concerns about possible genetical interactions with other Influenza virus, particularly with the deadly H5N1 (Avian Flu).

Health Ministers from 193 countries of the World Health Organization are meeting in Geneva (Switzerland) to draw up plans to fight the epidemic.

"We have reasons to fear an interaction of the virus A (H1N1) with others, including the H5N1, the avian flu, with has a high mortality rate among birds, but little effect in humans. This interaction would result in a much more dangerous influenza A" declared today Margaret Chan, the director of the WHO.

An Epidemic Nobody Talks About

While the international community is focused on the H1N1 virus, West Africa is experiencing a meningitis epidemic that could be easily contained but has already killed 1,900 persons and infected more than 56,000.

Médecins sans Frontières (MSF) (aka Doctors without Borders) have launched one of the largest vaccination campaigns in history, in collaboration with the World Health Organization and Chad, Niger and Nigeria governments.

In order to prevent the epidemic to extend, 270 groups of MSF are on the "battle field", each group being able to vaccinate 1500 persons daily. A minimum of 7 million persons need to be vaccinated for the mass immunization campaign to be efficient.

Baconic Plague: Much Ado About Nothing?

In a press briefing on Friday 1 May in Stockholm, scientists at the European Center for Disease Prevention and Control (ECDC) estimated that 80% of the European population could be affected by the Influenza A/H1N1 virus (new "politically correct" name for the swine flu) but that in most cases, it would be only a "mild form of flu".

Only the eldery and patients with chronic diseases, who have a weaker immune system, would be at risk of developing a more serious illness, and so the Health Authorities had to focus on protecting these vulnerable people.

A mild form of flu? Does it mean just another type of seasonal flu among others? And in this case have WHO, the media and politics been over reacting and exaggerating the thread?

At the same time, Mexican authorities report that the situation is improving and have reduced the number of confirmed cases.

WHO Raises Swine Flu Pandemic Alert To Level 5

Seems that we have never been so close to an influenza pandemic since the Hong Kong Flu pandemic in 1968, as the World Health Organization raised the pandemic alert level to phase 5, just one level below phase 6 (declared pandemic).

WHO and other Health Authorities around the world were expecting that the next pandemic would come from a mutant strain of H5N1 (or other avian strains like H7N1 or H9N2)and laboratories were working on developing a vaccine against these candidates.

Debunking The Swine Flu Conspiracy Theory

Less than a week after the fist report of the deadly swine flu outbreak in Mexico, the Conspiracy Theory has gone viral too and is spreading over the Internet much faster than the H1N1 around the world.

The way the official Health Services communicate and how the information is then relayed in mainstream media do not help hindering the propagation of bioterrorism or biological warfare rumors.

Journalists are using complex medical or genetical terminology without enough explanation, while some of these informations can only be understood by virologists or physicians.

Confronted with such an overwhelming mass of contradictory messages, the natural tendancy is to adhere to the first story that seems coherent. And Conspiracy storytellers are masters in the art of building coherent fables.

Swine Flu: The WHO Warns About Possible Pandemic Risk

"It's a potential pandemic because it is infecting people." said Margaret Chan,the Director-General of the World Health Organization (WHO), about the unknown and strange flu that has killed at least 149 people in Mexico and may have infected up to a thousand.

The alarm is also coming from the U.S., where the virus has infected height people. The Center for Disease Control and Prevention (CDC) has warned that the spread of the virus appears to be out of control.

"Be prepared for the worst. The situation is very serious and we are very concerned, and we do not know if we can contain the spread of this virus" said the director of CDC's Public Health, Anne Schuchat.

WHO Raises Swine Flu Pandemic Alert Level

On Monday, the World Health Organisation (WHO) raised the level of influenza pandemic alert from phase 3 to phase 4 (on a scale of 6), indicating that efforts to contain the spread of the virus had failed.

Keiji Fukuda, Head of the WHO Global Influenza Programme, said that outbreaks in Mexico, the U.S. and Spain demonstrate that the H1N1 virus expansion can't be hindered but does not require to close the fronters or to restrict travels, but "it is considered prudent for people who are ill to delay international travel and for people developing symptoms following international travel to seek medical attention".

Epidemiological data demonstrate human-to-human transmission and the ability of the virus to cause community-level outbreaks.

Although not yet a pandemic, the situation has to be considered very seriously worlwide.

Swine Flu: No Reason To Panic

Although the risk for the swine flu outbreaks to spark a pandemic are real, there is no reason to panic.

For almost 10 years now, World Health Organization and Public Health services woldwide are getting prepared for an H5N1 (Avian Flu) pandemic and have strenghten their emergency procedures, including early identification of the strain, prophylaxis, vaccine production capacity and coordination of the different players.

The current strain of H1N1 Swine Flu virus seems to be able to spread from human to human, but it is much less fatal than the H5N1 Avian Flu, and measures already designed to contain H5N1 would be efficient to limit the effect of a Swine Flu pandemic.

The strain has been quickly identified, and industrial labs are ready to produce large quantity of vaccine on WHO request.

Alert: Deadly Flu Outbreak In Mexico City

"We are faced with a new influenza virus, whose symptoms are: fever over 39 degrees, cough, severe headache, muscle aches and joints, irritation of the eyes and nasal discharge" said Health Minister Jose Angel Cordova, on Thursday night.

While the authorities recognized investigating 16 "suspicious" deaths, the World Health Organization says that there are about 800 suspected cases of swine flu, with 57 deaths in the region of Mexico and similar reported cases in the San Luis Potosi region in the center of the country.
