Hopelessness key component of mood disorder

Hopelessness key component of mood disorder
Theres depression, and then theres double depression.

Sound bad" It is, as per Thomas Joiner, Florida State University Distinguished Research Professor and the Bright-Burton Professor of Psychology, who has identified hopelessness as a distinguishing feature of double depression in a new paper reported in the Journal of Affective Disorders. The finding could help therapists diagnose and treat the mood disorder.

Double depression occurs when an individual who suffers from dysthymia, a persistent case of mild depression marked by low energy, falls into a major depressive state. It is not a new concept, but psychology experts know little about the characteristics that distinguish double depression from dysthymia or major depression alone, as per Joiner.

Its clinically important because it is under-recognized and harder to treat than either dysthymia or major depression by themselves, Joiner said. The hopelessness result is significant, and it suggests that therapists should particularly focus on this feature early and often in the therapy of double-depressed patients.

Joiner, along with FSU doctoral student Kathryn Gordon, Joan Cook from the Veterans Affairs Medical Center in Philadelphia and Michel Herson from Pacific University in Oregon, studied the psychological assessments of 54 adults who entered a community-based psychiatric outpatient facility for non-psychotic adults ages 55 and older. Questionnaires were given to patients before starting therapy to measure depression, hopelessness, anxiety and their sense of control over their own lives.........

Massachusetts General Hospital (MGH) surgeons have performed the first total hip replacement using a joint socket lined with a novel material invented at the MGH. An advance over first-generation highly crosslinked polyethylene, which was also developed at MGH and significantly reduced a serious complication of early hip implants, the new material may be applied in replacements for a wider variety of joints in a more diverse group of patients.

We think this material could be used for any joint in the body and in any implant design, even those demanding higher flexion and more mobility, says Orhun Muratoglu, PhD, co-director of the Harris Orthopdics Biomechanics and Biomaterials Laboratory (OBBL) at MGH, who developed the new material in collaboration with researchers at the Cambridge Polymer Group.

Total replacements for hips and other joints were developed in the late 1960s, but it soon became apparent that hip implants could start loosening about 5 years after surgery and would eventually fail completely. A team led by William Harris, MD, DSc, now director emeritus of the MGH OBBL, investigated this complication and observed that long-term friction of the implants head against the polyethylene-lined joint socket would break off small particles of polyethylene. The bodys immune system reacted against these foreign particles, eventually destroying adjacent bone tissue and causing the implant to loosen a condition called periprosthetic osteolysis.........

Unintended Pregnancy Predicts Feelings That Parenting Is A Burden

Unintended Pregnancy Predicts Feelings That Parenting Is A Burden
The relationship between a mother and her infant is believed by a number of to be the foundation of healthy childhood development, but scientists at the University of Missouri-Columbia have found pregnancy acceptance to be the first step in forming the mother/child bond.

Analyzing data collected from the national evaluation of the Early Head Start program, Jean Ispa, professor and co-chair of the Department of Human Development and Family Studies in the College of Human Environmental Science (HES), and her colleagues, found associations between how accepting mothers were of being pregnant and their toddlers' security of attachment. In the study, 173 young, low-income black mothers, who either were pregnant or had delivered within the past 11 months, were questioned regarding their feelings about pregnancy. When children were about a year old, their attachment security to their mothers was assessed.

"The relation between mothers' pregnancy acceptance and toddler attachment security is noteworthy because if attachment problems continue into the later years, the child could have self-esteem problems, difficulty learning and a harder time forming relationships," Ispa said.

The scientists also observed that mothers who were not accepting of their pregnancies had a greater tendency to later feel that parenting is burdensome. These findings suggest a need for policies that support reproductive education, as per Ispa. In addition, pregnant women who struggle to accept motherhood may benefit from policies that encourage social service professionals to screen for low acceptance of pregnancy and provide extra support to women who are not happy to be pregnant.........

Smokers who see more ads for smoking-cessation products

Smokers who see more ads for smoking-cessation products
The more magazine ads smokers see for the nicotine patch and other quit-smoking aids, the more likely they are to try to quit smoking and be successful -- even without buying the products, finds a new Cornell study.

"We believe that the reason may be that important 'spillover effects' from advertising may be occurring, which has important implications for advertising for a wide range of health products," said Alan Mathios, professor of policy analysis and management at Cornell and a co-author of the study, published in an upcoming issue of the Journal of Political Economy and winner of best conference paper at the 2007 American Marketing Association's Public Policy and Marketing Conference, May 31-June 2, in Washington, D.C.

Mathios noted that the results of this study may also apply to other types of pharmaceutical advertising. For example, when patients discuss with their physicians an advertised drug that lowers cholesterol, physicians will often recommend such health behavior changes as diet and exercise, creating a positive spillover effect from the advertising.

Using databases on the consumer behavior and magazine-reading habits of 28,303 current or former smokers and advertising data in 26 consumer magazines, Mathios and three Cornell colleagues explored the impact of advertising of smoking-cessation products on quitting decisions.........

How Diet And Exercise Enhance Longevity

How Diet And Exercise Enhance Longevity
The traditional prescriptions for a healthy lifesensible diet, exercise and weight controlextend life by reducing signaling through a specific pathway in the brain, as per Howard Hughes Medical Institute scientists who discovered the connection while studying long-lived mice.

They said their findings underscore the importance of maintaining a healthy lifestyle and may also offer promising research directions for understanding and treating diabetes and Alzheimers disease.

Howard Hughes Medical Institute investigator Morris F. White and colleagues published their findings in the July 20, 2007, issue of the journal Science. Akiko Taguchi and Lynn Wartschow in Whites laboratory in the Division of Endocrinology at Childrens Hospital Boston and Harvard Medical School were co-authors of the research article.

In their experiments, the scientists sought to understand the role of the insulin-like signaling pathway in extending lifespan. This pathway governs growth and metabolic processes in cells throughout the body. The pathway is activated when insulin and insulin-like growth factor-1 switch on proteins inside the cell called insulin receptor substrates (Irs).

Other scientists had shown that reducing the activity of the pathway in roundworms and fruitflies extends lifespan. Despite those tantalizing clues, White said, The idea that insulin reduces lifespan is difficult to reconcile with decades of clinical practice and scientific investigation to treat diabetes.........

Why Placebo Effect Varies From Person To Person

Why Placebo Effect Varies From Person To Person
Why do some people experience a placebo effect that makes them feel better when they receive a sham therapy they believe to be real while other people dont respond at all to the same thing, or even feel worse".

A new study from the University of Michigan Health System may help explain why.

Using two different types of brain scans, U-M scientists have observed that the extent to which a person responds to a placebo therapy is closely associated with how active a certain area of their brain becomes when theyre anticipating something beneficial.

Specifically, the research finds strong links between an individuals response to a placebo painkiller, and the activity of the neurotransmitter known as dopamine in the area of the brain known as the nucleus accumbens. Thats a small region at the center of the brain thats involved in our ability to experience pleasure and reward, and even to become addicted to the high caused by illicit drugs.

The new research, reported in the July 19 issue of the journal Neuron, builds on research previously published by the same U-M team in 2005. That study was the first to show that just thinking a placebo medicine will relieve pain is enough to prompt the brain to release its own natural painkillers, called endorphins, and that this corresponds with a reduction in how much pain a person feels.........

The end of barroom brawls

The end of barroom brawls
The link between alcohol and aggression is well known. Whats not so clear is just why drunks get belligerent. What is it about the brain-on-alcohol that makes fighting seem like a good idea" And do all intoxicated people get more aggressive" Or does it depend on the circumstances".

University of Kentucky psychology expert Peter Giancola and his student Michelle Corman decided to explore these questions in the laboratory. One theory about alcohol and aggression is that drinking impairs the part of the brain involved in allocating our limited mental resourcesspecifically attention and working memory. When we can only focus on a fraction of whats going on around us, the theory holds, drunks narrow their social vision, concentrating myopically on provocative cues and ignoring things that might have a calming or inhibiting effect.

The researchers tested this idea on a group of young Kentucky men. Some of the men drank three to four screwdrivers before the experiment, while others stayed sober. Then they had them all compete against another person in a somewhat stressful game that mandatory very quick responses. Every time they lost a round, they received a shock varying in intensity. Likewise, when they won a round they gave their opponent a shock. The idea was to see how alcohol affected the mens belligerence, as measured by the kinds of shocks they chose to hand out.........

Alcohol Related Visits To Emergency Care

Alcohol Related Visits To Emergency Care
Changes to the UK licensing laws have trebled the number of overnight visits to emergency care for alcohol related problems, reveals research in Emergency Medicine Journal.

The new licensing law, which allows alcohol to be available around the clock, took effect in November 2005.

The legislation was introduced in a bid to curb the amount of binge drinking and associated crime and disorder, and boost public safety.

The study findings are based on emergency care visits to one inner city London teaching hospital across two separate months, before and after the changes had been introduced.

Only those adults aged over 16, and who had been drinking before they came to the emergency department, were included in the audit.

The emergency care department at the hospital is one of the largest in the UK, and close to an array of licensed premises in central London.

The figures showed that in March 2005, before the licensing law changes, more than 10,000 visits were made to the department. In March 2006, there were 3% fewer visits.

But the number of overnight visits increased, and the proportion of those with alcohol related problems trebled.

In March 2005, there were over 2700 overnight visits to emergency care. But in March 2006, there were more than 3100 overnight visits, equivalent to a rise of 15% over the two months.........

Vitamin C offers little protection against colds

Vitamin C offers little protection against colds
Vitamin C containg food
Unless you run marathons, you probably wont get much protection from common colds by taking a daily supplemental dose of vitamin C, as per an updated review of 30 studies.

Conducted over several decades and including more than 11,000 people who took daily doses of at least 200 milligrams, the review also shows that vitamin C (ascorbic acid) does little to reduce the length or severity of a cold, as per the scientists at the Australian National University and the University of Helsinki.

However, they observed that people exposed to periods of high stress such as marathon runners, skiers and soldiers on sub-arctic exercises were 50 percent less likely to catch a cold if they took a daily dose of vitamin C.

For most people, the benefit of the popular remedy is so slight when it comes to colds that it is not worth the effort or expense, the authors say. It doesnt make sense to take vitamin C 365 days a year to lessen the chance of catching a cold, said co-author Harri Hemil, a professor in the Department of Public Health at University of Helsinki in Finland.

The review appears in the latest issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international organization that evaluates medical research. Systematic reviews draw evidence-based conclusions about medical practice after considering both the content and quality of existing medical trials on a topic.........

Ability to listen to 2 things

Ability to listen to 2 things
Your ability to listen to a phone message in one ear while a friend is talking into your other earand comprehend what both are sayingis an important communication skill thats heavily influenced by your genes, say scientists of the National Institute on Deafness and Other Communication Disorders (NIDCD), one of the National Institutes of Health. The finding, reported in the August 2007 issue of Human Genetics, may help scientists better understand a broad and complex group of disorderscalled auditory processing disorders (APDs)in which individuals with otherwise normal hearing ability have trouble making sense of the sounds around them.

Our auditory system doesnt end with our ears, says James F. Battey, Jr., M.D., Ph.D., director of the NIDCD. It also includes the part of our brain that helps us interpret the sounds we hear. This is the first study to show that people vary widely in their ability to process what they hear, and these differences are due largely to heredity.

The term auditory processing refers to functions performed primarily by the brain that help a listener interpret sounds. Among other things, auditory processing enables us to tell the direction a sound is coming from, the timing and sequence of a sound, and whether a sound is a voice we need to listen to or background noise we should ignore. Most people dont even realize they possess these skills, much less how adept they are at them. Auditory processing skills play a role in a childs language acquisition and learning abilities, eventhough the extent of that relationship is not well understood.........

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.
