2008-2009 Influenza Season Week 35 ending September 5, 2009
CDC surveillance for the week ending September 5, 2009: 20.5% of specimens tested positive for influenza, 97% of subtyped A viruses were 2009 H1N1, one pediatric death was reported, and eleven states plus Guam saw widespread activity.
Drug
Vivus Set to Apply for FDA Approval for Qnexa
Vivus plans to seek FDA approval for Qnexa, a combination of phentermine and Topamax. Across two late-stage trials of 1,267 and 2,487 patients, those on the drug lost about 9% of body weight, nearly double the 5% the FDA requires, and lowered blood lipids and blood sugar.

Suicide: A National Concern
Marking World Suicide Prevention Day, the piece opens with “Janie,” a Midwestern high school sophomore whose therapist called her mildly depressed months before she killed herself. Her mother says Janie knew how to answer questions so she would not be hospitalized.
Disease
Why do People Die from the Flu?
Influenza is blamed for about 36,000 U.S. deaths a year, more than 90 percent of them elderly. The piece explains the virus itself is not fatal: deaths usually follow secondary bacterial or viral pneumonia in people with weakened immunity, often as the patient seems to be recovering.

Scientists recycle fat into "liquid gold"
Stanford researchers turned fat removed by liposuction into induced pluripotent stem cells. They say the fat cells reprogram more efficiently and are ready right away, where skin cells need three weeks in culture, and they avoid mouse feeder cells and cross-species contamination.

Why Mammography is NOT an Effective Breast Cancer Screen
Dr. Len Saputo reviews the limits of mammography, clinical breast exams, ultrasound, MRI and PET scans, then makes the case for breast thermography. Early infrared scanners produced misdiagnoses, but he says modern versions rest on research covering more than 300,000 women.
Drug
Another Shocking Warning About Swine Flu Vaccine
German lung specialist Wolfgang Wodarg warned that the H1N1 vaccine's nutrient solution uses cancerous animal cells, raising fears about injecting them. Mercola adds that a BMJ study found more than half of public hospital doctors and nurses would refuse the vaccine.
Government
CDC recommendations for use of antiviral drugs in flu treatment and prevention
CDC's updated interim guidance for the 2009-2010 season recommends oseltamivir or zanamivir for everyone hospitalized with suspected or confirmed influenza, and generally for people at higher risk of complications, including children under 5 and adults 65 and older.
Drug
Fish-Killing Toxin Could Kill Cancer Cells
ARS and NOAA researchers report in Toxicon that euglenophycin, the algal toxin blamed for killing more than 21,000 striped bass at a North Carolina fish farm in 2002, resembles a fire ant venom alkaloid known to inhibit tumours and may have cancer-killing properties.
Disease
Cognition Negatively Affected by High Blood Pressure
The Maine-Syracuse Longitudinal Study, running over 20 years in adults aged 18 to 83, ties higher blood pressure to worse cognition: every 10-point rise in diastolic pressure came with 7 percent greater risk of mental impairment. NIH plans a larger trial into why.
Disease
Retrovirus potential risk factor for prostate cancer
Utah and Columbia researchers found DNA from the retrovirus XMRV in 27 percent of more than 200 prostate cancers, against 6 percent of non-cancerous tissue, with viral proteins almost exclusively in malignant cells. If the link proves causal, tests and vaccines might follow.

September: National Addiction and Recovery Month
Marking the twentieth National Addiction and Recovery Month, this piece offers advice for the early days of sobriety: start slowly with a few non-negotiable habits, treat addiction as an illness that needs care rather than a choice, and rebuild order in neglected parts of life.

U.S Prepares for Flu Hospitalizations
The CDC says it is preparing for 1.8 million flu hospitalizations and as many as 90,000 deaths in the coming months, with swine flu cases already surging in August. For Aug. 23-29 hospitalizations rose to 9,079, and H1N1 made up 97 percent of reported flu cases.
Disease
Largest ever Alzheimer’s gene study unveils dementia mysteries
A genome-wide study of 16,000 people, published in Nature Genetics, links two genes, CLU and PICALM, to common Alzheimer's disease, while French researchers found a third. They are the first such genes identified since APOE4 in 1993.

Yoga Study Proves Efficacy for Chronic Pain Sufferers
In a West Virginia University study, 43 chronic back pain sufferers took 90-minute yoga classes for 24 weeks while 47 received standard care. The yoga group reported less functional disability, less pain and fewer depressive symptoms, and many cut their pain medication.
Miscellaneous
New bills may give you medical freedom
Citing supplement company Daniel Chapter One, this piece urges readers to press Congress to pass three Ron Paul bills: the Freedom of Health Speech Act, the Health Freedom Act and the Congressional Responsibility and Accountability Act. One would end FDA prior restraint of nutrient-disease claims.
Drug
Why You Should Get Off Prescription Acid-Reducing Drugs ASAP
In a study of healthy volunteers who had never had heartburn, more than 40 percent developed heartburn, acid regurgitation or dyspepsia in the weeks after eight weeks of proton pump inhibitors were stopped, a rebound in acid secretion that can lead to dependence on the drugs.
