University of Minnesota president has prostate cancer
Bob Bruininks said the disease was caught early and wrote on his website that his condition is highly treatable with an excellent prognosis for recovery. The National Cancer Institute counts more than 180,000 US diagnoses and about 25,000 deaths a year.

Genetic Variant Linked to Deadly Prostate Cancer
Wake Forest researchers compared 4,849 men with aggressive prostate cancer to 12,205 with slow-growing disease and found the variant rs4054823 carried a 25 percent higher risk of aggressive disease. Coauthor Jianfeng Xu says a predictive panel test may be possible.

Despite Decline of H1N1, Pandemic May Not be Over
GlaxoSmithKline will keep shipping swine flu vaccine even as H1N1 wanes. The CDC estimates 80 million Americans have been infected since March 2009, yet 90% of the most vulnerable are unimmunized, and European experts warn that declining pandemic viruses can mutate.
Disease
Obstructive sleep apnea may worsen diabetes
University of Chicago researchers studied 60 type 2 diabetes patients and found severe obstructive sleep apnea went with poor blood sugar control: mild, moderate and severe apnea came with HbA1C increases of 49, 93 and 269 percent. Which condition drives the other is unclear.

Multistate Outbreak of Human Salmonella Typhimurium Infections
A CDC investigation traced 85 Salmonella Typhimurium infections across 31 states to African dwarf frogs; 63% of cases reported frog exposure versus 3% of controls. Matching isolates turned up in aquariums in four case-patients' homes.

CDC swine flu update: 52nd week
CDC's January 8 update recorded four more pediatric swine flu deaths in the week ending January 2, up from two, for 188 since August 30. Influenza activity decreased slightly, yet the agency released a letter signed by more than 30 provider groups promoting H1N1 vaccination.

Alternative Explanation for Why People Get Fat
Gary Taubes argues people do not get fat because they overeat but overeat because their fat tissue is accumulating fat. He blames dietary carbohydrates, especially fructose, which supply glycerol-3-phosphate and raise insulin so that fat stays locked in.

Breakthrough Diagnosis Tool Uncovers What’s REALLY Causing Your Health Problems
An overview of Autonomic Response Testing, a biofeedback-enhanced exam developed by Dietrich Klinghardt that reads changes in muscle tone. It sets out the four steps, from stressing the body electromagnetically, psychologically, structurally or biochemically to interpreting the response.

Fewer children die from swine flu in December
The CDC reported two pediatric deaths from 2009 H1N1 during the week of Dec 20 to 26, a small number next to earlier weeks, bringing the total to 183 since Aug 30. Doctor visits rose slightly, hospitalizations held steady, and HHS secretary Kathleen Sebelius urged Americans to get vaccinated.
Disease
Homocysteine may be only a biomarker for diseases
High homocysteine has been tied to stroke, Alzheimer's, Parkinson's, epilepsy, MS and ALS, but lowering it with vitamin therapy does not prevent vascular disease, suggesting it may be only a biomarker. Italian researchers did report that normalizing levels helped patients with cognitive impairment.

Rush Limbaugh treated for chest pain
Rush Limbaugh, 58, was admitted to Queen's Medical Center in Honolulu with chest pain and released after doctors found no evidence of heart disease. The piece lists cardiac, digestive, musculoskeletal and respiratory causes of chest pain.

Diabetes genes linked to lipid metabolism
Helmholtz Zentrum Munchen researchers measured 163 metabolic products in blood from 1,800 KORA participants and identified variants in nine genes tied to disturbances in lipid metabolism, including MTNR1B and GCKR, already linked to diabetes. They may serve as early biomarkers.
Disease
Disinfectants may promote growth of superbugs
Irish researchers report in Microbiology that Pseudomonas aeruginosa cultures exposed to rising doses of a disinfectant adapted to survive both the disinfectant and the antibiotic ciprofloxacin, pumping antimicrobials out of their cells and mutating toward resistance.

New Hampshire woman suffers anthrax
New Hampshire health officials say a resident is in critical condition with what is probably gastrointestinal anthrax, the state’s first case since 1957. The source remains unidentified; one report suspects African drums used at a university drum circle.

Teresa Heinz undergoes surgery for breast cancer
Heinz, 71, had lumpectomies on both breasts at Massachusetts General in early October and starts radiotherapy in January 2010. She has not decided on chemotherapy, weighing her age and the side effects against doctors' claim it would lift her survival odds to 99 percent.

Fat hormone linked to both cancer and Alzheimer's
Catherine Roe's Neurology study found people with cancer less likely to have Alzheimer's and vice versa. The piece points to hormones as a link: a JAMA study following 2,000 people for 12 years found Alzheimer's in 25% of those with the lowest leptin levels versus 6% of those with the highest.
Disease
Alzheimer's linked to cancer
In the Cardiovascular Health Study of 3,000 people aged 65 and older, those with Alzheimer's at the start had a 69% lower risk of hospitalization for cancer, and among white participants who already had cancer the risk of Alzheimer's was 43% lower.
