In pandemic, parents who get reminders more likely to get kids vaccinated Posted: 18 Nov 2013 04:32 PM PST A new study found that the state immunization registry -- the public health database that tracks vaccinations -- can be an effective tool to encourage influenza vaccinations during a pandemic.

Renal stenting does not improve outcomes for renal artery stenosis patients Posted: 18 Nov 2013 04:32 PM PST According to the findings from an American national research trial, people who suffer from a narrowing of the arteries that lead to the kidneys, or renal artery stenosis, do not experience better outcomes when renal stenting is used. Instead, a comprehensive regimen of drug and medical therapies works just as well.

Statin use not linked to a decline in cognitive function Posted: 18 Nov 2013 04:32 PM PST Based on the largest comprehensive systematic review to date, researchers concluded that available evidence does not support an association between statins and memory loss or dementia.

The big male nose: Why men's noses are bigger than women's Posted: 18 Nov 2013 01:00 PM PST Why are men's noses bigger than women's? The answer, according to a new study lies in our physiology. Men's noses are about 10 percent larger than female noses, on average, because males have more lean muscle mass, which requires more oxygen for muscle tissue growth and maintenance. It also explains why we have smaller noses than our ancestors.

Promiscuous mouse moms bear sexier sons Posted: 18 Nov 2013 12:29 PM PST Biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young. They attract more females by making more urinary pheromones, but smelling sexier shortens their lives.

Consistent bed, wake time linked to healthier weight Posted: 18 Nov 2013 10:30 AM PST Prior research has shown not getting enough sleep can impact your weight, but new research finds the consistency of your bed time and wake time can also influence body fat.

Low-fat fish oil changes cancer tissue in prostate cancer, study shows Posted: 18 Nov 2013 10:30 AM PST Men with prostate cancer who ate a low-fat diet and took fish oil supplements had lower levels of pro-inflammatory substances in their blood and a lower cell cycle progression score, a measure used to predict cancer recurrence, than men who ate a typical Western diet, researchers found.

Preventing antibiotic resistance in hospital textiles Posted: 18 Nov 2013 07:24 AM PST "Antibiotic resistance threatens a return to the pre-antibiotic era". The World Health Organization uses this strong expression when referring to a phenomenon that is rapidly spreading: the increasing resistance of microorganisms to antimicrobial medicines, such as antibiotics. WHO estimates indicate that the excess mortality due to resistant bacterial hospital infections exceeds 25,000 every year, in Europe.

Structure of key part of deadly nipah virus captured Posted: 18 Nov 2013 06:15 AM PST Researchers have solved the structure of a key protein in the Nipah virus, which could pave the way for the development of a much-needed antiviral drug.

Study reveals potential breakthrough in hearing technology Posted: 18 Nov 2013 06:14 AM PST Computer engineers and hearing scientists have made a potential breakthrough in solving a 50-year-old problem in hearing technology: how to help the hearing-impaired understand speech in the midst of background noise.

Long-term oral contraceptive users twice as likely to have serious eye disease Posted: 18 Nov 2013 06:14 AM PST Research has found that women who have taken oral contraceptives for three or more years are twice as likely to suffer from glaucoma, one of the leading causes of blindness which affects nearly 60 million worldwide. The researchers caution gynecologists and ophthalmologists to be aware of the fact that oral contraceptives might play a role in glaucomatous diseases, and inform patients to have their eyes screened for glaucoma if they also have other risk factors.

Depression in pregnancy: New study shows preferences for therapy over medication Posted: 18 Nov 2013 06:14 AM PST Women with depression in the perinatal period experience a high degree of conflict in deciding whether and how to treat their depression, but strongly prefer treatments other than antidepressant medications, reports a study.

With board games, it's how children count that counts Posted: 18 Nov 2013 05:12 AM PST Researchers have examined whether playing board games can help children improve math skills. It turns out the method children use to count as they move their tokens on a board game is directly linked to their gains in numeracy. The new study suggests parents and teachers need to direct children's attention to the numbers on the board game in order to realize math gains.

Influence of pro-smoking media messages lasts 7 days, study finds Posted: 18 Nov 2013 05:12 AM PST A first-of-its-kind study finds that an exposure to a single pro-smoking media message increases college-aged students' risk of using tobacco for seven days. The project is the first to attempt to quantify the persistence that cigarette advertising and other pro-smoking media messages have on consumers and has implications for policies that limit tobacco advertising and other efforts aimed at curbing youth tobacco use.

Untreated HIV carriers transmit resistant viruses Posted: 18 Nov 2013 05:09 AM PST Human-Immunodeficiency Viruses that resist AIDS medicines are primarily transmitted by people who are not actually undergoing treatment. In order to prevent a spread of the resistant viruses increased efforts in prevention and early diagnosis of new infections are needed, as concluded by the Swiss HIV Cohort Study.

Human error most common cause of birth asphyxia: Poor fetal monitoring in 50% of cases, Norwegian study shows Posted: 18 Nov 2013 05:09 AM PST Human error is the most common cause of infant asphyxiation at birth, new research shows. Inadequate fetal monitoring, lack of clinical skills, and failure to obtain senior medical staff assistance are most often cited in Norwegian compensation claims following birth asphyxia.

Comparing outcomes of device for chest compressions vs manual CPR Posted: 17 Nov 2013 12:57 PM PST Researchers assessed whether cardiopulmonary resuscitation (CPR) in which chest compressions are delivered with a mechanical device would result in superior 4-hour survival in patients with out-of-hospital cardiac arrest compared to CPR with manual chest compression.

Rate of aortic valve replacement for elderly patients increased; outcomes improved Posted: 17 Nov 2013 12:57 PM PST Researchers have assessed procedure rates and outcomes of surgical aortic valve replacement among 82,755,924 Medicare fee-for-service beneficiaries between 1999 and 2011.

Researchers develop formula to more accurately calculate 'bad' cholesterol Posted: 17 Nov 2013 12:54 PM PST Researchers have developed a more accurate way to calculate low-density lipoprotein (LDL) cholesterol, the so-called "bad" form of blood fat that can lead to hardening of the arteries and increase the risk of heart attack and stroke. If confirmed and adopted by medical laboratories that routinely calculate blood cholesterol for patients, the researchers say their formula would give patients and their doctors a much more accurate assessment of LDL cholesterol.

Novel gene variant discovered in severe childhood asthma Posted: 17 Nov 2013 12:54 PM PST An international scientific team has discovered a gene associated with a high risk of severe childhood asthma. The specific gene variant may be an actual cause of this form of asthma, a leading cause of hospitalization in young children.
