Week 46 Sets Record H1N1 US Pediatric Fatalities
Recombinomics Commentary 17:13
November 28, 2009
There were 35 influenza associated pediatric deaths reported week 46: NH (1), MA (1), RI (2), PA (2), MN (1), MO (1), NC (2), FL (3), TN (1), TX (2), CO (1), NM (8), WA (1), CA (1), IL (3), IN (1), KY (1), NY (1), SC (2)
The above description of the 35 fatal pediatric deaths in week 46 in the US will be published on Monday. The 35 ties that daily record set two weeks ago, and the new entries raise the 2009/2010 season total to 178, which is a new record. The 138 last week represented the highest tally since adolescent fatalities became mandatory, when 142 died in 2003/2004. 178 is a new all time high, but it will be broken each week until there is a break, which may not happen in 2010.
Abstract Background: The novel A/H1N1 influenza virus, which recently emerged in North America is most closely related to North American H1N1/N2 swine viruses. Until the beginning of 2009, North American swine H1N1/N2 viruses have only sporadically infected humans as dead-end hosts. In 2009 the A/H1N1 virus acquired the capacity to spread efficiently by human to human transmission. The novel A/H1N1 influenza virus has struck thousands of people in more than 70 countries and killed more than 140, representing a public health emergency of international concern. Here we have studied properties of hemagglutinin of A/H1N1 which may modulate virus/ receptor interaction. Results: Analyses by ISM bioinformatics platform of the HA1 protein of North American swine H1N1/N2 viruses and the new A/H1N1 showed that both groups of viruses differed in conserved characteristics that reflect a distinct propensity of these viruses to undergo a specific interaction with swine or human host proteins or receptors. Swine H1N1/N2 viruses that sporadically infected humans featured both the swine and the human interaction pattern. Substitutions F71S, T128S, E302K, M314L in HA1 of swine H1N1 viruses from North America are identified as critical for the human interaction pattern of A/H1N1 and residues D94, D196 and D274 are predicted to be "hotspots" for polymorphisms which could increase infectivity of A/H1N1 virus. At least one of these residues has already emerged in the A/H1N1 isolates from Spain, Italy and USA. The domain 286- 326 was identified to be involved in virus/receptor interaction. Conclusion: Our results (i) contribute to better understanding of the origin of the novel A/H1N1 influenza virus, (ii) provide a tool for monitoring its molecular evolution (iii) predicts hotspots associated with enhanced infectivity in humans and (iv) identify therapeutic and diagnostic targets for prevention and treatment of A/H1N1 infection.

Abstract
Gulf War illness (GWI) affects a significant percentage of veterans of the 1991 conflict, but its origin remains unknown. Associated with some cases of GWI are increased incidences of amyotrophic lateral sclerosis and other neurological disorders. Whereas many environmental factors have been linked to GWI, the role of the anthrax vaccine has come under increasing scrutiny. Among the vaccine’s potentially toxic components are the adjuvants aluminum hydroxide and squalene. To examine whether these compounds might contribute to neuronal deficits associated with GWI, an animal model for examining the potential neurological impact of aluminum hydroxide, squalene, or aluminum hydroxide combined with squalene was developed. Young, male colony CD-1
mice were injected with the adjuvants at doses equivalent to those given to US military service personnel. All mice were subjected to a battery of motor and cognitive-behavioral tests over a 6-mo period postinjections. Following sacrifice, central nervous system tissues were examined using immunohistochemistry for evidence of inflammation and cell death. Behavioral testing showed motor deficits in the aluminum treatment group that expressed as a progressive decrease in strength measured by the wire-mesh hang test (final deficit at 24 wk; about 50%). Significant cognitive deficits in water-maze learning were observed in the combined aluminum and squalene group (4.3 errors per trial) compared with the controls (0.2 errors per trial) after 20 wk. Apoptotic neurons were identified in aluminum-injected animals that showed significantly increased activated
caspase-3 labeling in lumbar spinal cord (255%) and primary motor cortex (192%) compared with the controls. Aluminum-treated groups also showed significant motor neuron loss (35%) and increased numbers of astrocytes (350%) in the lumbar spinal cord. The findings suggest a possible role for the aluminum adjuvant in some neurological features associated with GWI and possibly an additional role for the combination of adjuvants. doi: 10.1385/NMM:9:1:83

SUMMARY
A single intradermal injection of the adjuvant-oil squalene induces T cell mediated arthritis in DA rats. The chain of events leading from nonspecific provocation of the immune system to arthritis is largely unknown. Previous studies have demonstrated that lymph node (LN) cells are of pathogenic importance, i.e. cells from LNs draining the injection site can transfer arthritis to naïve DA rats. Recently we have demonstrated cellular uptake of adjuvant oil in draining lymph nodes but also that nondraining
LNs become hyperplastic and harbour arthritogenic cells. Here, we aimed to determine from which time-point prior to arthritis onset arthritogenic cells appear in draining inguinal and nondraining axillary/ brachial LNs, respectively. We demonstrated that the ability to transfer arthritis was strongly dependent on the time-point after adjuvant-injection with clear-cut differences between draining and nondraining LN cells. Cells harvested at day 5 postinjection (p.i) were not able to transfer arthritis, while at day 8 p.i, a first wave of arthritogenic cells appeared in draining LNs. The ability to transfer arthritis was associated with a pro-inflammatory cytokine profile as indicated by the IL-1
b and IFN g expression in cells from draining LNs. Subsequently, at day 11 p.i., just before arthritis onset, arthritogenic cells appeared also in nondraining LNs. These results shed new light on the induction of arthritic diseases, implicating a two-step mechanism for the development of pathogenic cells. Firstly, a pro-inflammatory burst in responding lymphoid organs leading to a local pool of arthritogenic cells and, secondly, a transmission of arthritogenecity to other LNs and precipitation of disease in peripheral joints.

H1N1 deaths increase as mutations combine - vaccine & antiviral resistant, lung hemorrhaging virus

H1N1 Mutation Resists Swine Flu Vaccine in France
The World Health Organization has reported that global deaths from the H1N1 virus have increased by 1000 in the past week. At the same time, the H1N1 virus is mutating, with each mutation causing different effects in patients, and combining in some cases. The national medical laboratory in Britain reported that the H1N1 vaccine would probably not be effective against the variant of the swine flu virus found in the Ukraine flu outbreak. This variant, in which the virus uses D225G as a receptor binding domain, causes bleeding in the lungs. Another H1N1 mutation results in the resistance to treatment with antiviral medication.
Swine flu vaccine won't prevent infection with deadly H1N1 mutated virus
The same mutation that results in acute respiratory damage, due to the location of the viral infection, has been called a "low reactor" to the vaccine. This means that the vaccine will not provide an immune response for that strain of virus adequate to prevent infection.
Lung hemorrhaging caused by swine flu
Lung hemorrhaging is being caused by a swine flu mutation that has been reported in China, Norway, France, and the Ukraine as having a receptor binding domain of D225G. In the United States, there has been a report of fatalities in patients with hemorrhaged lungs, but the mutation has not been confirmed.
Tamiflu-resistant H1N1 mutation
A strain of H1N1 that is resistant to Tamiflu, an antiviral medication, has been found worldwide. Clusters occurred in North Carolina and Wales. One case of H1N1 found in France with the D225G designation was also resistant to Tamiflu.
Swine flu mutation combinations
To date, the H1N1 mutations in the Ukraine have included bleeding in the lungs and resistance to the vaccine, and a case in France included bleeding in the lungs and resistance to antiviral treatment. The common factor appears to be the severe symptom caused by D225G.

Clearly there is no topic discipline left on ATS. The rules concerning proper attribution of external content sources seem to have vanished as well....

Keep hitting the ALERT option. Truly off topic posts will be addressed by the mods.
Hang in there.

Popularity has it's drawbacks.
Spin the wheel and pick a thread.
I personally like the one about Mexico and the H8N5.

There is a dedicated thread for discussion of alternative pathogens here.
No one is trying to deny anyone's right to participate, they're merely asking that off topic posts be taken to the proper threads.

Purpose built by who and for what reason?
Even before you recommended people use that idiotic thread I had my suspicions that you had started it. I'm certainly not going to co-operate in keeping a purpose-built strawman alive.

Lets see if I'm understanding this right. A person that has received a swine flu shot is given the live virus. They are around somebody that has the swine flu that person can develope a mutated type of the swine flu possibly a more lethal type. They would have known this because one Doctor wrote about this. Maybe not all mutated strains of the virus infect people this way. Now what is that new seasonal flu shot going to do since that one is going on the market or has been out there?
