Nurses As 'Soft Targets' Of Drug Company Promotion
Nurses As 'Soft Targets' Of Drug Company Promotion
Nursing education fails to prepare graduates to deal with the pharmaceutical industry's promotional tactics, and many nurses appear to accept promotional materials uncritically, according to an analysis of the nursing literature recently published.
Report Links Health Insurance Status With Cancer Care
An article in the January issue of CA: A Cancer Journal for Clinicians explores the impact health insurance status has on cancer screening, diagnosis, and survival rates.
Knee Brace Generates Electricity From Walking
A new energy-capturing knee brace can generate enough electricity from walking to operate a portable GPS locator, a cell phone, a motorized prosthetic joint or an implanted neurotransmitter. The researcher, who called the device "a cocktail-napkin idea," says knee joints are uniquely suited for this endeavor.
Natural Secretion Marks Difference Between Mole And Melanoma
One might call it a tale of two melanocytes. Given the same genetic mutation, why does one melanocyte shut down growth and become a relatively benign mole, while another rages out of control and develops into deadly melanoma? In trying to tease out the answer to this simple question, researchers have uncovered a protein that stops the growth of melanoma, a cancer that develops from pigment-producing cells in the skin called melanocytes. If this natural anti-cancer agent can be produced and delivered to tumors, it might serve as a targeted chemotherapy for metastatic melanoma, a condition which is "basically untreatable" today.
Teenage Fathers Are More Likely To Have Babies Affected By Birth Problems Than Fathers Over 40
Teenage fathers are at increased risk of having babies born with birth problems ranging from pre-term delivery or low birth weight, through to death in or near to the time of delivery, according to new research in Human Reproduction journal. In contrast, the study also found that fathers aged 40 and over were not at increased risk of having babies affected by these problems. Previous studies have shown that younger men can have lower sperm counts, semen volume, total numbers of spermatozoa and percentage of motile sperm. Immature sperm may be associated with adverse birth outcomes, possibly as a result of the abnormal formation of the placenta in the uterus.
Third Cousins Have Greatest Number Of Offspring, Data From Iceland Shows
Scientists have established a substantial and consistent positive correlation between the kinship of couples and the number of children and grandchildren they have. The study, which analyzes more than 200 years of deCODE's comprehensive genalogical data on the population of Iceland, shows that couples related at the level of third cousins have the greatest number of offspring. These new findings suggest that the recent and dramatic demographic shift experienced in Iceland -- from a rural society to a highly urbanized one -- may serve to slow population growth, as individuals are exposed to a much broader range of distantly related potential mates.
