Swine Flu Update

Cliff Notes for “Swine flu: One Killer virus, three key questions.”

swine flu virusBy Ilene

Brendan Maher and Declan Butler, authors of a recently published Nature article “Swine flu: One killer virus, three key questions,” set out to answer three questions about the H1N1 virus. Here’s what they found. 

How does it kill?

Sherif Zaki, head of the infectious-disease pathology branch at the Centers for Disease Control, discusses his team’s observations from their pathological studies.    

1.  The H1N1 virus penetrates deep into the alveoli (the terminal air sacs in the lungs). In contrast, the seasonal flu viruses tend to infect cells higher in the upper airways. This deep penetration is reminiscent of the action of the H5N1 avian flu virus. Zaki commented: “[H1N1] is like avian flu on steroids.”  Why might this be?

Zaki says that his observations fit well with recent research looking at the mechanism of infection. A group led by Mikhail Matrosovich at Philipps University Marburg in Germany and Ten Feizi at Imperial College London studied sialyl glycans, glycoproteins that the flu virus binds to in order to gain entry to human cells. Although seasonal strains of H1N1 bind mostly to versions of the glycoproteins known as α2-6, the researchers found that the new pandemic H1N1 can also bind to a version called α2-3, which is found in greater proportion in the lower respiratory tract.

2.  In patients who have died, co-infection was common with H1N1.  Zaki’s group observed infection with bacteria such as Staph aureus or Streptococcus pneumoniae in about a third of the fatal swine-flu cases. However, in the remaining two thirds of fatal cases, the virus was lethal alone.  The damage seen in the lungs is characterized as ‘diffuse alveolar damage,’ reflecting a very difficult to treat state of respiratory distress syndrome. According to Zaki’s research, about 90% of the fatal cases had some underlying medical condition.

Zaki expects the number of flu cases to increase as the flu season “ramps up.”

How does H1N1 spread?

Brendan Maher visited Peter Palese’s laboratory at Mount Sinai School of Medicine where testing for how the viruses spread is being carried out. Researchers John Steel and Anice Lowen compared the transmissibility of H1N1 to that of seasonal flu using a guinea pig model. Their data indicate that the H1N1 virus transmits as efficiently as seasonal flu viruses, which is consistent with real-world data showing…

Double-Edged Sword: Swine Flu and Vaccines

By guest author Terry Doherty and Ilene, your editor

Double-Edged Sword: Swine Flu and Vaccines

There’s plenty that is unknown about the swine flu and the swine flu vaccine.  If searches on the internet are any indication, deciding whether or not to be vaccinated may be a tough, emotionally charged decision for many people.  So how – without having the background to write a swine flu grant proposal, conduct the research, and get the thing published in the New England Journal of Medicine – do we decide whether or not to get a swine flu shot?  

One way is to attempt to evaluate and weigh the risks of the vaccine against the risks of the flu.  That is how I approach the subject, but it’s easier said than done.  As is often the case with medical interventions, the risks are not fully known. And even if we could carefully assess the risks, our underlying assumptions may be wrong.  Percent risks are averages collected by studying large populations.  We may not be one of the statistical average.  Then there are the gaps in the available data, and own biases and belief systems.  Our view of the world affects our analysis and often we are not even aware of how large of an effect those biases may play.   

In Vaccine War: Autism, Flu and Science, TIME, Maia Szalavitz discusses how emotion and biases play a large part in our risk-benefit assessments:

Just in time for the national roll-out of the new H1N1 flu vaccine, Wired Magazine and the Atlantic have weighed in on the ongoing vaccine war: Wired has a profile of Paul Offit, a vaccine researcher and pediatrician who has consistently spoken out in favor of vaccination and pointed to the lack of evidence linking vaccines and autism; the Atlantic checks in with a piece questioning the science suggesting that flu vaccines and antiviral drugs prevent people from dying.

Both articles have elicited heated debate all over the Web: Amy Wallace, who wrote Wired’s piece, excerpted below, has received vitriolic criticism and attacks from vaccine opponents, setting records for page views…

This debate over vaccination doesn’t seem likely to end any time soon. For critics, vaccines…

With leaked trades in their personal accounts already costing two Fed presidents their jobs, and a third - vice chair Richard Clarida - currently on the ropes amid speculation he will soon follow, a few weeks ago we joked that if forces within the Fed want to get rid of all the hawks, they should just leak Esther George - the Fed's last remaining uberhawk - trading record.

Price and Volume Swing Analysis on Bitcoin and Silver

Courtesy of Read the Ticker

Many take guidance from news, pundits or advisors. Well sometimes the swings of price and volume are a better measure of what happens next.

The big boys do not accumulate or distribute in single 1 second trade, they build positions over weeks, months and years. They use price swings in the market to build or reduce positions, and you can see their intent by studying swings of price and volume and applying Tim Ord logic as written in his book called 'The Secret Science of Price and Volume: Techniques for Spotting Market Trends, Hot Sectors, and the Best Stocks'.

Tim Ord is a follower of Richard Wyckoff logic, his book has added to the studies of Richard Wyckoff, Richard Ney and Bob Evans.

Ethereum's Turn To Outshine Bitcoin Is Coming, UBS Says

Courtesy of ZeroHedge View original post here.

After a stellar start to the year, which saw its price soar to an all time high above $4,100, trouncing virtually all of its crypto peers, Ethereum has stagnated in recent weeks, with its place in the spotlight taken by bitcoin whose impressive outperformance has been the result of now confirmed speculation that a bitcoin futures ETF is coming. It also meant that what has traditionally been a close correlation between the two largest cryptos has broken in favor of the larger peer; it would also suggest that ethereum is trading about $1000 cheap vs bitcoin.

Crude Oil Cleared For Blast Off On This Dual Breakout?

Courtesy of Chris Kimble

Is Crude Oil about to blast off and hit much higher prices? It might be worth being aware of what could be taking place this month in this important commodity!

Crude Oil has created lower highs over the past 13-years, since peaking back in 2008, along line (1).

It created a “Double Top at (2), then it proceeded to decline more than 60% in four months.

The countertrend rally in Crude Oil has it attempting to break above its 13-year falling resistance as well as its double top at (3).

A successful breakout at (3) would suggest Crude Oil is about to mo...

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
