Curbing college drinking problems

Curbing college drinking problems
Parental monitoring can reduce high-school drinking and, as a result, have a protective effect on students drinking at college, says research published this week in the online open access journal Substance Abuse Treatment, Prevention, and Policy.

The findings strengthen the idea that certain parental practices throughout high school and perhaps college could be used to curb high-risk drinking in older adolescents. Underage drinking is associated with many negative outcomes in this group, including suicide, high-risk sexual activity and an increased chance of alcohol dependence.

Scientists from the Center for Substance Abuse Research at the University of Maryland College Park, Maryland, USA interviewed over 1,200 students for the research, which forms part of the College Life Study. This is an ongoing, longitudinal, prospective investigation of health-risk behaviors in college students, including alcohol and other drug use.

The team assessed parental monitoring and student alcohol consumption (in drinks per day) in high school using surveys in the summer before the students attended a large public university in the mid-Atlantic. Students were followed up with a personal interview in their first college year to assess their alcohol consumption over the past year.........

Torrefacto-roasted coffee has higher antioxidant properties

Torrefacto-roasted coffee has higher antioxidant properties
Torrefacto-roasted coffee has higher antioxidant properties than natural roast, as per the dissertation defended by a biologist of the University of Navarra, Isabel Lopez Galilea. She has emphasized in her study that the addition of sugar during the roasting process increases the development of compounds with high antioxidant activity.

The researcher of Department of Food Sciences, Physiology and Toxicology of the University of Navarra analyzed eleven varieties of commercial coffee for her study, which was entitled "The Influence of Torrefacto Roasting on the Principal Components of Coffee and its Antioxidant and Pro-oxidant Capacity".

As this scientist of the School of Sciences emphasized, numerous studies have shown the benefits of this drink. In particular, it is considered to be one of the best sources for antioxidants in the diet; these substances help to protect us against free radicals, which are a cause of premature aging and certain diseases. Coffee has an antioxidant capacity which is ten times higher than other drinks, such as red wine and tea.

The antioxidant capacity varies as per the preparation method

In order to carry out this research, Isabel Lopez analyzed the coffee consumption habits of the inhabitants of Navarra, via 300 surveys. The results showed that Navarrans consume an average of 125 ml of coffee per day, with consumption slightly higher among women. In addition, they primarily consume ground coffee resulting from a mixture of natural roast and torrefacto-roast coffees, and the coffee is generally prepared with Italian or mocha coffee makers, followed by the filter, espresso and pump methods.........

Moderate alcohol consumption can lower cardiac risk

Moderate alcohol consumption can lower cardiac risk
Prior studies have pointed out the benefits of moderate alcohol consumption as a factor in lowering cardiovascular risk. In a study conducted by the Department of Family Medicine at the Medical University of South Carolina and reported in the March 2008 issue of The American Journal of Medicine, scientists observed that middle-aged non-drinkers who began consuming moderate amounts of alcohol saw an immediate benefit of lower cardiac disease morbidity with no change in mortality after four years.

Studying 7,697 people between 45 and 64 who were non-drinkers and who were participating in the Atherosclerosis Risk in Communities (ARIC) study over a 10 year period, the authors observed that 6% began moderate alcohol consumption (1 drink per day or fewer for women and 2 drinks per day or fewer for men) during the follow-up period. After 4 years of follow-up, new moderate drinkers had a 38% lower chance of developing cardiovascular disease than did their non-drinking counterparts. Even after adjusting for physical activity, Body Mass Index, demographic and cardiac risk factors, this difference persisted.

The study also identified a subset of new drinkers who consumed only wine. When comparing non-drinkers to wine-only drinkers, drinkers of other types of alcohol, and heavy drinkers, the wine-only drinkers had the most significant reduction in cardiovascular events. Drinkers of other types of alcohol also had an advantage over non-drinkers, but the difference did not reach statistical significance.........

Chemistry of Mother-daughter conflict

Chemistry of Mother-daughter conflict
A combination of negative mother-daughter relationships and low blood levels of serotonin, an important brain chemical for mood stability, may be lethal for adolescent girls, leaving them vulnerable to engage in self-harming behaviors such as cutting themselves.

New University of Washington research indicates that these two factors in combination account for 64 percent of the difference among adolescents, primarily girls, who engage in self-harming behaviors and those who do not.

Girls who engage in self harm are at high risk for attempting suicide, and some of them are dying, said Theodore Beauchaine, a UW associate professor of psychology and co-author of a new study. There is no better predictor of suicide than prior suicide attempts.

The paper, co-authored by Sheila Crowell, one of his doctoral students, appears in the current issue of the Journal of Consulting and Clinical Psychology.

Beauchaine said the relationship between the level of mother-daughter conflict and self-harming behavior was not strong. There was a stronger relationship between serotonin levels and self-harming behavior. But when both factors were considered together, the relationship to self-harming behaviors was very strong.

Most people think in terms of biology or environment rather than biology and environment working together, he said. Having a low level of serotonin is a biological vulnerability for self-harming behavior and that vulnerability increases remarkably when it is paired with maternal conflict.........

Excessive drinking among the elderly

Excessive drinking among the elderly
One out of ten older adults on Medicare reports drinking more alcohol than is recommended, as per a new study from Brandeis University.

Even though alcohol problems are more prevalent in younger people, a substantial proportion of elderly adults are consuming alcohol in amounts that exceed recommended guidelines, said co-author of study Elizabeth Merrick, senior scientist at Brandeis Universitys Heller School for Social Policy and Management. The study sheds light on a complex problem that has received scant attention and is often missed by health care and other providers, she said.

Reported in the Journal of the American Geriatrics Society, the study reviewed data about 12,413 Medicare beneficiaries aged 65 or older. Merrick and her colleagues observed that 9 percent engaged in unhealthy drinkingconsuming more than thirty drinks per month, or drinking four or more drinks on any day in a typical month. The study, based on a 2003 Medicare survey, also reported that two-thirds of beneficiaries do not drink, while one-quarter drink within the recommended guidelines.

As per the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the American Geriatrics Society, risky drinking among those 65 years and older occurs when a person consumes more than seven drinks per week or more than three drinks on a single day. OOther guidelines suggest that the single-occasion drink limit should be no more than two drinks, and that women should drink even lower overall amounts than men.........

Costly placebo works better than cheap one

Costly placebo works better than cheap one
A 10-cent pill doesn't kill pain as well as a $2.50 pill, even when they are identical placebos, as per a provocative study by Dan Ariely, a behavioral economist at Duke University.

"Physicians want to think it's the medicine and not their enthusiasm about a particular drug that makes a drug more therapeutically effective, but now we really have to worry about the nuances of interaction between patients and physicians," said Ariely, whose findings appear as a letter in the March 5 edition of the Journal of the American Medical Association.

Ariely and a team of collaborators at the Massachusetts Institute of Technology used a standard protocol for administering light electric shock to participants wrists to measure their subjective rating of pain. The 82 study subjects were tested before getting the placebo and after. Half the participants were given a brochure describing the pill as a newly-approved pain-killer which cost $2.50 per dose and half were given a brochure describing it as marked down to 10 cents, without saying why.

In the full-price group, 85 percent of subjects experienced a reduction in pain after taking the placebo. In the low-price group, 61 percent said the pain was less.

The finding, from a relatively small and simplified experiment, points to a host of larger questions, Ariely said.........

Study uncovers cause of flu epidemics

Study uncovers cause of flu epidemics
The exchange of genetic material between two closely related strains of the influenza A virus may have caused the 1947 and 1951 human flu epidemics, as per biologists. The findings could help explain why some strains cause major pandemics and others lead to seasonal epidemics.

Until now, it was believed that while reassortment when human influenza viruses swap genes with influenza viruses that infect birds causes severe pandemics, such as the Spanish flu of 1918, the Asian flu of 1957, and the Hong Kong flu of 1968, while viral mutation leads to regular influenza epidemics. But it has been a mystery why there are sometimes very severe epidemics like the ones in 1947 and 1951 that look and act like pandemics, even though no human-bird viral reassortment event occurred.

There was a total vaccine failure in 1947. Scientists initially thought there was a problem in manufacturing the vaccine, but they later realized that the virus had undergone a tremendous evolutionary change, said Martha Nelson, lead author and a graduate student in Penn States Department of Biology. We now believe that the 1947 virus did not just mutate a lot, but that this unusual virus was made through a reassortment event involving two human viruses.

So we have observed that the bipolar way of looking at influenza evolution is incorrect, and that reassortment can be an important driver of epidemic influenza as well as pandemic influenza, said Nelson, whose teams findings are reported in the current issue of PLoS Pathogens. We have discovered that you can also have reassortment between viruses that are much more similar, that human viruses can reassort with each other and not just with bird viruses.........

Gene mutations linked to longer lifespans

Gene mutations linked to longer lifespans
Mutations in genes governing an important cell-signaling pathway influence human longevity, researchers at the Albert Einstein College of Medicine of Yeshiva University have found. Their research is described in the March 4 issue of the Proceedings of the National Academy of Sciences.

The report is the latest finding in the Einstein scientists ongoing search for genetic clues to longevity through their study that by now has recruited more than 450 Ashkenazi (Eastern European) Jews between the ages of 95 and 110. Descended from a small founder group, Ashkenazi Jews are more genetically uniform than other groups, making it easier to spot gene differences that are present. In 2003, this study resulted in the first two longevity genes ever identifiedfindings that have since been validated by other research.

The present study focused on genes involved in the action of insulin-like growth factor (IGF-I), a hormone that in humans is regulated by human growth hormone. Affecting virtually every cell type in the body, IGF-I is crucially important for childrens growth and continues contributing to tissue synthesis into adulthood. The IGF-I cell-signaling pathway is triggered when IGF-I molecules circulating in blood plasma latch onto receptors on the surface of cells, causing a signal to be sent to the cells nucleus that may, for example, tell that cell to divide.........

Women are Treated Less Frequently than Men with Statins

Women are Treated Less Frequently than Men with Statins
Women and men experience a similar prevalence of adverse drug reactions in the therapy of coronary artery disease; however, women are significantly less likely than their male counterparts to be treated with statins, aspirin, and beta-blockers as per a new study by scientists at Rush University Medical Center. The study is reported in the recent issue of the journal Gender Medicine.

"Developments in disease recognition and novel therapy strategies have led to a significant decline in overall cardiovascular death rate among men, but these dramatic improvements have not been observed in women," said Dr. Jonathan R. Enriquez, lead author of the study and resident internal medicine doctor at Rush. "This may be correlation to underutilization of medical therapies such as aspirin, ß-blockers, ACE inhibitors or statins".

In association with Dr. Annabelle Volgman and the Rush Heart Center for Women, the study involved 304 consecutive patients with coronary artery disease at the outpatient cardiology clinic at Rush. A retrospective observational analysis waccording toformed to determine the usage and adverse reactions reported from aspirin, ß-blockers, angiotensin-converting-enzyme (ACE) inhibitors or statins. Baseline clinical characteristics were also determined to identify the independent association of gender on usage of standard medical coronary artery disease therapys.........

Links Betweenarts Education And Cognitive Development

Links Betweenarts Education And Cognitive Development
Learning, Arts, and the Brain, a study three years in the making, is the result of research by cognitive neuroresearchers from seven leading universities across the United States. In the Dana Consortium study, released recently at a news conference at the Dana Foundation's Washington, DC headquarters, scientists grappled with a fundamental question: Are smart people drawn to the arts or does arts training make people smarter?

For the first time, coordinated, multi-university scientific research brings us closer to answering that question. Learning, Arts, and the Brain advances our understanding of the effects of music, dance, and drama education on other types of learning. Children motivated in the arts develop attention skills and strategies for memory retrieval that also apply to other subject areas.

The research was led by Dr. Michael S. Gazzaniga of the University of California at Santa Barbara. "A life-affirming dimension is opening up in neuroscience," said Dr. Gazzaniga, "to discover how the performance and appreciation of the arts enlarge cognitive capacities will be a long step forward in learning how better to learn and more enjoyably and productively to live. The consortium's new findings and conceptual advances have clarified what now needs to be done".........

Did you know?
Adolescents who suffer physical injuries are vulnerable to emotional distress in the months following their hospitalization, yet almost 40 percent of hospitalized adolescents interviewed for a new study had no source for the follow-up medical care that could diagnose and treat symptoms of post-traumatic stress. These young trauma survivors are at risk for high levels of post-traumatic stress and depressive symptoms, as well as high levels of alcohol use, according to research by researchers at the Harborview Injury Prevention and Research Center.
