NIST releases draft report on South Carolina furniture fire study
Major factors contributing to a rapid spread of fire at the Sofa Super Store in Charleston, S.C., on June 18, 2007, included large open spaces with furniture providing high fuel loads, the inward rush of air following the breaking of windows, and a lack of sprinklers, according to a draft report released October 28, 2010, for public comment by the National Institute of Standards and Technology (NIST). The fire trapped and killed nine firefighters, the most firefighter fatalities in a single event since 9/11.

Medicine & Health news
Patients receiving dialysis are at a heightened risk for sudden cardiac death
Approximately 500,000 Americans require dialysis to treat kidney disease; of that population nearly half of the deaths that occur are caused by cardiovascular disease. Dialysis patients are at elevated risk for sudden cardiac death, but physicians are unclear why these deaths occur because little research has been done to examine how to best manage heart disease in this high-risk population.
Women with high job strain have 40 percent increased risk of heart disease
Women who report having high job strain have a 40 percent increased risk of cardiovascular disease, including heart attacks and the need for procedures to open blocked arteries, compared to those with low job strain, according to research presented at the American Heart Association's Scientific Sessions 2010.
Spike in dengue has Brazil on alert for epidemic
(AP) -- Health officials say Brazil is at risk of an even deadlier outbreak of dengue fever as the South American nation enters its long, wet summer, when standing water turns into breeding ponds for the mosquitoes that spread the disease.
Doctors brace for possible big Medicare pay cuts
(AP) -- Breast cancer surgeon Kathryn Wagner has posted a warning in her waiting room about a different sort of risk to patients' health: She'll stop taking new Medicare cases if Congress allows looming cuts in doctors' pay to go through.
Study suggests physicians wait longer for brain recovery after hypothermia Rx in cardiac arrest
Heart experts at Johns Hopkins say that physicians might be drawing conclusions too soon about irreversible brain damage in patients surviving cardiac arrest whose bodies were for a day initially chilled into a calming coma.
Synchronizing a failing heart
November 14, 2010 – One of the largest, most extensive worldwide investigations into heart failure, led by the University of Ottawa Heart Institute (UOHI), conclusively proves that a new therapeutic implant synchronizes and strengthens a fading heart beat while reducing risk of death by 24% compared to the current treatment.
Poor sleep quality increases inflammation, study finds
People who sleep poorly or do not get enough sleep have higher levels of inflammation, a risk factor for heart disease and stroke, researchers have found.
Having first-degree relative with atrial fibrillation linked with increased risk
An examination of the heritability of atrial fibrillation (AF) among more than 4,000 participants in the Framingham Heart Study finds the occurrence of AF in first-degree relatives was associated with AF risk after adjustment for established AF risk factors and AF-related genetic variants, according to a study that will appear in the November 24 issue of JAMA. The study is being released early online because it will be presented at the American Heart Association's annual meeting.
Study: Hospital CPR quality is worse at night
CPR quality is worse during in-hospital cardiac arrests occurring overnight than those that happen during the day, according to a new University of Pennsylvania School of Medicine study that will be presented at the American Heart Association's annual Scientific Sessions on November 14. The researchers found that chest compression rates varied more at night - often dipping well below the rate per minute that's necessary to properly circulate blood - than during resuscitation efforts during the day, and rescuers paused for longer when switching between chest compressions and defibrillator shocks at night.
Vitamin D deficit doubles risk of stroke in whites, but not in blacks
Low levels of vitamin D, the essential nutrient obtained from milk, fortified cereals and exposure to sunlight, doubles the risk of stroke in whites, but not in blacks, according to a new report by researchers at Johns Hopkins.
Less salt in teenagers' diet may improve heart health in adulthood
Eating smaller amounts of salt each day as a teenager could reduce high blood pressure, heart disease and stroke in adulthood, according to research presented at the American Heart Association's Scientific Sessions 2010.
fMRI predicts outcome to talk therapy in children with an anxiety disorder
A brain scan with functional MRI (fMRI) is enough to predict which patients with pediatric anxiety disorder will respond to "talk therapy," and so may not need to use psychiatric medication, say neuroscientists from Georgetown University Medical Center.
Death of spouse, child may cause higher heart rate, other dangers
The death of a spouse or child can cause elevated heart rate and other potentially harmful heart rhythm changes among the recently bereaved, according to research presented at the American Heart Association's Scientific Sessions 2010.
Sleep makes your memories stronger
As humans, we spend about a third of our lives asleep. So there must be a point to it, right? Scientists have found that sleep helps consolidate memories, fixing them in the brain so we can retrieve them later. Now, new research is showing that sleep also seems to reorganize memories, picking out the emotional details and reconfiguring the memories to help you produce new and creative ideas, according to the authors of an article in Current Directions in Psychological Science, a journal of the Association for Psychological Science.
Studies: Drug, device help treat heart failure
(AP) -- Millions of people with mild or moderate heart failure got good news Sunday, with studies showing a Pfizer drug and a device from Medtronic can boost survival and cut trips to the hospital by patients having trouble breathing.
DNA sequence variations linked to electrical signal conduction in the heart
Scientists studying genetic data from nearly 50,000 people have uncovered several DNA sequence variations associated with the electrical impulses that make the heart beat. The findings, reported in Nature Genetics, may pave the way for a greater understanding of the mechanisms for abnormal heart rhythms and sudden cardiac death.
Research uncovers extensive natural recovery after spinal cord injury
A study led by researchers in the Department of Neurosciences at the University of California, San Diego School of Medicine shows unexpected and extensive natural recovery after spinal cord injury in primates. The findings, to be published November 14 in the advance online edition of Nature Neuroscience, may one day lead to the development of new treatments for patients with spinal cord injuries.

Cilantro ingredient can remove foul odor of 'chitlins'
With chitlins about to make their annual appearance on Thanksgiving, Christmas, and New Year's Day menus, scientists have good news for millions of people who love that delicacy of down-home southern cooking, but hate the smell. They are reporting the first identification of an ingredient in cilantro that quashes the notoriously foul odor of chitlins — a smell known to drive people from the house when chitlins are cooking. Their report appears in ACS' Journal of Agricultural and Food Chemistry.

Embryonic stem cell culturing grows from art to science
