Watching and Waiting

While the numbers of new cases of swine flu have been declining in many regions, including the United States, it is too early to know whether or not there will be subsequent waves of disease.

"Based on my experience with new diseases and the lessons learned from past pandemics, I think we should remain cautious and observe the evolution of the pandemic over the next six to 12 months before declaring victory," World Health Organization Director General Margaret Chan tells Swiss newspaper Le Temps. (World Health Official Says Swine Flu Still a Threat)

Although the WHO is remaining "cautious," changes in the virus’s genome that increase its virulence and resistance to Tamiflu are becoming more common.  Dr. Henry Niman, expert in flu virus evolution, believes another wave of illnesses will occur in early 2010.  In addition, he believes resistance to Tamiflu will become "fixed," similarly to how this genetic change evolved in the seasonal H1N1 virus.  (See Flu Update: Tamiflu resistance and Ukraine update, and Efficacy of Roche’s Flu Drug Tamiflu In Doubt, by David Phillips.)

WHO: H1N1 swine flu pandemic will stick around for another year

The World Health Organization warned government health authorities to remain vigilant on the H1N1 swine flu pandemic, saying the virus could mutate before vaccines can help it dissipate.

The World Health Organization is confident that the H1N1 swine flu pandemic will be under control in a year’s time – however, WHO officials warned global governments to remain vigilant for any mutations in the troublesome bug.

Dr. Niman believes this wave will be more severe than the previous two--but not due to random mutations. Rather, this will result from the process of recombination. Due to recombination, increasingly greater transmission of aggressive variants (D225G, D225E and D225N) and Tamiflu-resistant viruses will occur.

Flu Update: Tamiflu resistance and Ukraine update

Roche’s Tamiflu and the Swine Flu 

By Ilene  

Illustration protection kit against Swine flu (Flu A H1N1) with Tamiflu - France

Part I: Tamiflu resistance
Part 2: Flu virus changes/Ukraine/update  

Tamiflu (oseltamivir) has been a big seller this year, with global sales soaring 362% to $1.93 billion in the first nine months. Driven by the threats of a swine flu pandemic, governments have been stockpiling the drug to the tune of $1.32 billion. (See Efficacy of Roche’s Flu Drug Tamiflu In Doubt, David Phillips): 

According to David Phillips:

Allegations have surfaced that Swiss drug maker Roche has misled governments and physicians alike on the efficacy of its popular drug Tamiflu in preventing complications, such as hospitalization from pneumonia or death, in otherwise healthy people afflicted with the flu — seasonal or the H1N1 (swine flu) version. If the company is unconvincing in refuting such claims, more than its reputation could be sullied.

Leveraging global concerns over avian and swine flu, Roche has seamlessly raised awareness of the purported need to treat the complications associated with the seasonal flu too. The company has successfully challenged conventional wisdom — that “rest and aspirin” be the preferred treatment option for seasonal flu — with marketing campaigns that resonate with reassuring efficacy claims for Tamiflu (oseltamivir)… [See Tamiflu media updates].

A scarcity of published data in the medical literature motivated the nonprofit research group Cochrane Collaboration to investigate — and verify — Tamiflu’s alleged efficacy claims, particularly on the drug’s effect on the risk of hospital admission and complications in otherwise healthy people with influenza. The Cochrane review and a linked investigation undertaken jointly by the British Medical Journal and the local Channel 4 News cast doubt on the efficacy and safety of Tamiflu — and also raises disturbing questions on the drug’s promotional and marketing activities condoned by regulators on both sides of the Atlantic.

Investigators disclosed that an often cited meta-analysis used as evidentiary support was based entirely on ten trials funded by Roche, only two of which were published in peer reviewed journals. The Cochrane reviewers could find no independently funded trials of Tamiflu for healthy adults. Troubling, too, former employees of the medical communcations company hired by Roche were alleged to have ghost written some of the manuscripts….

Swine Flu Virus: Changes and Consequences

Swine Flu Virus: Changes and Consequences 

By Ilene with guest expert Dr. Henry Niman

Russia and Ukraine take measures to combat swine flu

Background

Dr. Henry Niman heads the research company Recombinomics Inc. Recombinomics has a small group of researchers who analyze the sequence data from viral samples isolated from patients diagnosed with swine flu. Its website is a terrific place to find the newest information available. 

Dr. Niman has kindly been answering my questions regarding the H1N1 virus, its evolution, and the implications regarding the spread of disease. Because the terminology may be unfamiliar, a brief introduction may be helpful towards better understanding both the H1N1 virus and the swine flu disease.

Recombination

Flu viruses, including the H1N1 varieties, are known for quickly changing genetically. Recombination is the driver of rapid molecular evolution, a process whereby small bits of genetic information pass between viruses so a virus may quickly acquire a genetic variation that has previously evolved and already exists in the viral reservoir (the pool of viruses circulating in a population). Unlike sporadic mutations, recombination reflects the acquisition of genetic material that has withstood the Darwinian test of time. Compared to sporadic mutation, recombination is a quicker, non-random mechanism for genetic change.

Changes in the H1N1 viral genome are natural. The viral reservoir consists of wild-type viruses (the predominant viruses) and low levels of variants carrying a variety of different sequences called “polymorphisms.” While recombination is not the currently favored theory regarding how flu viruses evolve, Dr. Niman believes it is the correct theory. The theory of recombination as a mechanism for genetic change has led to accurate predictions about how the flu virus would evolve as infection rates increase. As the size of the viral reservoir continues to expand, viruses with genetic differences, “polymorphisms,” become more evident.

Ukraine Outbreak

The outbreak in Ukraine was initially described in many media reports as a new lung-blackening “mystery disease,” leading to many false and misleading Internet stories. According to Dr. Niman, it was clear from the start that H1N1 was killing an unusually high number of previously healthy young adults… (See Flu News: D225G Follow-up)

Dr. Niman wrote a number of commentaries on the rising death toll and the need to make the sequences public. He predicted the deaths would be associated with a receptor binding domain change in the wild-type H1N1 virus (the predominant virus) to…

Flu News: D225G Follow-up

By Ilene with guest expert Dr. Henry Niman

Swine Flu Precautions Continue For International Travellers

Dr. Henry Niman heads the research company Recombinomics Inc. Recombinomics has a small group of researchers who analyze the sequence data from viral samples isolated from patients diagnosed with swine flu.

I spoke with Dr. Niman last week about the evolution of the H1N1 virus as it circulates through the world’s population. These changes are natural—and Dr. Niman’s research on the subject allowed him to predict how the virus would change as infection rates increase and time goes on. The outbreak in Ukraine was initially described in many media reports as a new lung-blackening "mystery disease," leading to many false and misleading Internet stories. According to Dr. Niman, it was clear from the start that H1N1 was killing an unusually high number of previously healthy young adults. 

H1N1 infection seemed to cause more severe illness in Ukraine, and Ukraine officials asked the WHO for assistance. The WHO interfaced with Ukraine labs in Kiev and sent groups into western Ukraine to survey the problem and gather information. As part of the investigation, the WHO sent samples to Mill Hill in London, one of several regional centers that performs genetic analysis for the WHO.

Subsequently, the WHO issued several non-informative reports but held the sequences at Mill Hill for analysis. Dr. Niman wrote a number of commentaries on the rising death toll and the need to make the sequences public. He predicted the deaths would be associated with a receptor binding domain change in the wild-type H1N1 virus (the predominant virus) to a variant form, characterized by the D225G genetic marker. Wild-type H1N1 has a D at position 225 of the viral protein Hemagglutinin (HA), and is referred to as D225. The variant protein, D225G, has a genetic change causing a change in position 225 of the protein. "D" is the symbol for the aspartic acid which is present at position 225 of the wild-type protein. Glycine, symbol G, replaces aspartic acid in D225G variants. Hemagglutinin is one of two surface proteins projecting out from the surface of the virus. The function of the HA protein is to bind viral particles to susceptible cells in the host animal.

Flu News: What is the significance of D225G?

Swine Flu News: What is the significance of D225G?

By Ilene

Dr. Henry L. NimanWith the current rush of news about the swine flu virus morphing into more aggressive lung-shredding and tamiflu-resistant mutants, there is some confusion as to why these changes are being seen in people in "hotspots" around the world, with no clear connection to each other. Officials at the WHO and CDC suggest that the same mutations are arising spontaneously in multiple locations but this doesn’t quite make sense.  To better understand how changes in the swine flu virus may be occurring, I contacted Dr. Henry L. Niman, founder and president of Recombinomics.  Dr. Niman has been an active researcher in the evolution of flu virus.  His latest thoughts on the ongoing progression of the flu pandemic may be found at his website, Recombinomics.   

For a little background, the D222G mutation or D225G mutation (same mutation, different numbering system) was found in three cases in Norway ("Norway" mutation), and in other countries, including Brazil, China, Japan, Mexico, Ukraine, the United States, and more recently Hong Kong. The change in a single nucleotide results in an amino acid change in the virus’s receptor binding protein. This has the effect of allowing the virus to bind receptors in the lung tissue, rather than the more usual binding to cells in the upper airways. Theoretically, this may confer greater virulence to the virus, potentially leading to more severe disease as the infection invades deeper in the respiratory tract. This change was also seen in the 1918 flu pandemic, in some (but not all) cases. 

Recombinomics

The name of Dr. Niman’s company "Recombinomics" is taken from the word "recombine" or "recombination" – the driver of rapid molecular evolution and the emergence of infectious agents. Recombination* is a mechanism whereby small bits of genetic information pass between viruses so that a virus may quickly acquire a genetic change that evolved previously over the years in other viruses. Recombination is similar to reassortment, but with less genetic material being exchanged. 

Sporadic mutations do not usually lead to successful adaptive changes – often they have no effect or prove to be non-adaptive, with the mutation failing to be further replicated.  In contrast, recombination allows viruses to quickly alter their characteristics by acquiring genetic material that already exists in the viral reservoir (i.e., the pool of viruses circulating in a population). This…

Aussie Dollar About To Send Bullish Message To Precious Metals?

Courtesy of Chris Kimble.

The Australian Dollar and its ETF (NYSEARCA: FXA) have traded sideways for much of the past 4 years (see blue shaded area on chart above).

And since the Aussie Dollar and precious metals are highly correlated, this hasn’t helped gold and silver.

But this setup may be changing soon as a big test comes into play for the AU$.

It is currently testing falling resistance on a bullish falling wedge pattern.

If it succeeds in breaking out at (1), it will send metals and commodities a short-term bullish message. Stay tuned!

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...
