Singapore led study has shown that Hepatitis B Virus Infection (HBV) exposure increases the immune system maturation of infants, which may give a better survival advantage to counteract bacterial infection during early life. These findings radically modify the way that HBV vertical infection of neonates (mother-to-child) is portrayed, and present a paradigm shift in the [...]

Results from the first phase 1 trial of an Ebola vaccine based on the current (2014) strain of the virus are today published in The Lancet. Until now, all tested Ebola virus vaccines have been based on the virus strain from the Zaire outbreak in 1976. The results suggest that the new vaccine is safe, [...]

Researchers Solve Science Behind Scalp Cooling And The Reasons For Hair Loss In Cancer Treatment

The lowered temperature of the scalp could result in greatly reduced blood flow to the area, so that less of the drug finds its way to the hair follicles. It is also possible that cooling reduces the level of drug uptake in the region of the hair cells, or that the same effect is produced by a lowering of the metabolism.

Hair loss is one of the most distressing side-effects of cancer treatment and can even deter some patients from undergoing life-saving chemotherapy. But researchers at the University of Huddersfield are establishing the scientific basis for a rapidly-advancing scalp cooling technology that can ensure hair retention in a vast number of cases. There is also an [...]

Experience Saves Lives: Study Of Advanced Life-Support Reveals Big Differences In Adult Survival Rates

An advanced form of life support that takes over for the failing hearts and lungs of critically ill patients saves lives. But for adults, the odds of surviving depend on which hospital provides the life-supporting treatment – with the best odds at ones that use the technique dozens of times a year, a new study [...]

Less Futile End-Of-Life Care Observed Where Palliative Care Knowledge Is Greater

When nursing directors know more about palliative care, nursing home patients have less likelihood of experiencing disruptive end-of-life efforts such as feeding tubes.

When a nursing home patient is dying, aggressive interventions such as inserting a feeding tube or sending the patient to the emergency room can futilely exacerbate, rather than relieve, their distress. Palliative care focuses nursing home resources on providing comfort at the end of life, but nursing directors vary widely in their knowledge of it. [...]
