Easing job stress may ward off depression

NEW YORK (Reuters Health)April 27, 2009 – Reducing on-the-job stress and strain may lower the risk of depression, new research shows.

 Over a 10-year period, workers who initially reported having high-strain jobs but then later reported perceiving their jobs as being less stressful were at the same risk of major depression as their peers who worked at low-strain jobs for the entire time, Dr. JianLi Wang of the University of Calgary in Alberta and colleagues found.

 “These results indicated that interventions targeted to reducing job strain may significantly reduce the risk of depression,” they noted in a report in the American Journal of Epidemiology.

 In a given 30-day period, 4.4 percent of US workers have major depression, the researchers point out, and work stress, also known as job strain, has been linked to depression risk.

 To investigate how changes in job strain over time might influence people’s likelihood of becoming depressed, the researchers looked at 4,866 people participating in the Canadian National Population Health Survey. All had reported on their job strain status in 1994-1995 and again in 2000-2001.

 The researchers divided study participants into four groups: people with low job strain at both time points; people with high job strain at both points; people with low job strain at the first time point and high job strain at the second; and people who initially had high job strain and then reported low job strain.

 Among people with consistently high job strain, 8 percent had an episode of major depression during the study period, compared to 4 percent of those who had low job strain at both time points. For people whose jobs got less stressful, the risk of major depression was 4.4 percent, compared to 6.9 percent for people whose jobs became more stressful.

 Within the group of people with high job strain at both time points, the researchers found, only those who rated their health as good or excellent at the beginning of the study were at greater risk of major depression; those who rated their health as poor to fair weren’t at increased risk. “These participants may have accepted the reality of having poor health and of exposure to various risk factors for health,” Wang and colleagues suggest.

 Because how people see their job’s stressfulness can change frequently, the researchers call for future studies to measure job strain in shorter time increments to better understand how workplace stress relates to depression.

My 2 Cents:  This article really points to my job situation; a high stress job that landed me on a journey of major depression and short term disability.  It has taken me almost a year to recover, but I’m back and coping – but working at a snail’s pace compared to years before.

Lithium And The Brain: New Light On Bipolar Treatment Drugs

ScienceDaily (Apr. 27, 2009)Lithium has been established for more than 50 years as one of the most effective treatments for bipolar mood disorder. However, scientists have never been entirely sure exactly how it operates in the human brain.

Now, new research from Cardiff University scientists suggests a mechanism for how Lithium works, opening the door for potentially more effective treatments.

Laboratory tests on cells have shown that Lithium affects a molecule called PIP3 that is important in controlling brain cell signalling. Lithium suppresses the production of inositol, a simple sugar from which PIP3 is made.

Lithium inhibits inositol monophosphatase (IMPase) an enzyme required for making inositol. Importantly, this research shows that increasing the amount of IMPase causes higher levels of PIP3. This can then be reduced by lithium treatment.

High levels of IMPA2, a gene for a variant of IMPase, has previously been linked to bipolar mood disorder. This new result suggests that Lithium could counteract the changes in IMPA2.

Professor Adrian Harwood of Cardiff School of Biosciences, who led the research, said: “We still cannot say definitively how Lithium can help stabilise bipolar disorder. However, our research does suggest a possible pathway for its operation. By better understanding Lithium, we can learn about the genetics of bipolar disorder and develop more potent and selective drugs.

“Further, altered PIP3 signalling is linked to other disorders, including epilepsy and autism, so this well established drug could be used to treat other conditions. Research into Lithium could become very important over the next few years.”

Lithium is currently under clinical trial for the treatment of neurogenerative disorder amyotrophic lateral sclerosis (ALS).

The research, funded by the Wellcome Trust, is published in the journal Disease Models and Mechanisms.

How Cigarettes Calm You Down

ScienceDaily (Apr. 25, 2009) — The calming neurological effects of nicotine have been demonstrated in a group of non-smokers during anger provocation. Researchers writing in BioMed Central’s open access journal Behavioral and Brain Functions suggest that nicotine may alter the activity of brain areas that are involved in the inhibition of negative emotions such as anger.

Jean Gehricke led a team of researchers from the University of California who studied the effect of nicotine patches on the subjects’ tendency to retaliate in response to anger provocation. The subjects played a computer game and could see a video screen of another player who they believed to be their opponent, although, in fact, they were playing alone. After each round, the victor could give his opponent a burst of unpleasant noise – at a duration and volume set by the winner. In some of the subjects, nicotine was associated with a reduced tendency to retaliate, even after provocation by the ‘opponent’.

According to Gehricke, “Participants who showed nicotine-induced changes in anger task performance also showed changes in brain metabolism. Nicotine-induced reductions in length of retaliation were associated with changes in brain metabolism in response to nicotine in brain areas responsible for orienting, planning and processing of emotional stimuli”.

The authors say that their findings support the idea that people of an angry disposition are more susceptible to nicotine’s effects, and are therefore more likely to become addicted to cigarettes. They conclude, “Novel behavioral treatments that affect the cortical and limbic brain areas, like anger management training, may aid smoking cessation efforts in anger provoking situations that increase withdrawal and tobacco cravings”.

Herbal Remedy: Teens & Cannabis

Herbal Remedy: Teens Often Use Cannabis For Relief, Not Recreation, Study Finds

ScienceDaily (Apr. 24, 2009) — When legal therapies let them down, some teens turn to cannabis. A new study, published in BioMed Central’s open access journal Substance Abuse, Treatment, Prevention and Policy suggests that around a third of teens who smoke cannabis on a regular basis use it as a medication, rather than as a means of getting high.

Joan Bottorff worked with a team of researchers from the University of British Columbia, funded by the Canadian Institutes of Health Research, to conduct in-depth interviews with 63 cannabis-using adolescents. Of these, 20 claimed that they used cannabis to relieve or manage health problems. Bottorff said, “Marijuana is perceived by some teens to be the only available alternative for those experiencing difficult health problems when legitimate medical treatments have failed or when they lack access to appropriate health care”.

The most common complaints recorded were emotional problems (including depression, anxiety and stress), sleep difficulties, problems with concentration and physical pain. The teens’ experiences with the medical system were uniformly negative. The authors said, “Youth who reported they had been prescribed drugs such as Ritalin, Prozac or sleeping pills, stopped using them because they did not like how these drugs made them feel or found them ineffective. For these kids, the purpose of smoking marijuana was not specifically about getting high or stoned”.

The authors emphasize that the unmet medical needs of these teens are of key importance in these findings. In contrast to the unpleasant side effects of prescribed medications and long, ineffective legal therapies, cannabis provided these adolescents with immediate relief for a variety of health concerns. Of course, cannabis isn’t completely harmless, but as one of the respondents noted, “It’s not good for you, but then again, neither is McDonald’s and a lot of other things”.

Pain Relievers Appear Ineffective In Preventing Alzheimer’s In The Very Elderly

ScienceDaily (Apr. 23, 2009) — A new study shows that nonsteroidal anti-inflammatory drugs (NSAIDs), such as the pain relievers ibuprofen and naproxen, do not prevent Alzheimer’s disease or other forms of dementia. Instead, the risk of developing dementia in the study’s very elderly population (most were over age 83 when they developed dementia) was 66 percent higher among heavy NSAID users than among people who used little or no NSAIDs, according to research published online in Neurology®, the medical journal of the American Academy of Neurology.

Researchers identified 2,736 members of Group Health, an integrated healthcare delivery system, who did not have dementia when they enrolled in the study at an average age of 75. The investigators then followed these people for 12 years to see if they developed Alzheimer’s or other forms of dementia. They checked Group Health pharmacy records for NSAIDs (tracking both prescriptions and over-the-counter use) and also asked participants about their use of NSAIDs.

Of the participants, 351 people had a history of using NSAIDs heavily at the study’s start, and another 107 became heavy NSAID users during the follow-up period. Heavy use was defined as having prescriptions for NSAIDs at least 68 percent of the time in two years.

Meditation Hopeful for Depression

Meditation Provides Hope For People With Depression

ScienceDaily (Apr. 23, 2009) — People with severe and recurrent depression could benefit from a new form of therapy that combines ancient forms of meditation with modern cognitive behaviour therapy, early-stage research by Oxford University psychologists suggests.

The results of a small-scale randomised trial of the approach, called mindfulness-based cognitive therapy (MBCT), in currently depressed patients are published in the journal Behaviour Research and Therapy.

28 people currently suffering from depression, having also had previous episodes of depression and thoughts of suicide, were randomly assigned into two groups. One received MBCT in addition to treatment as usual, while the other just received treatment as usual. Treatment with MBCT reduced the number of patients with major depression, while it remained the same in the other group.

Professor Mark Williams and colleagues in the Department of Psychiatry at the University of Oxford will follow up the promising preliminary evidence from this small-scale study. They hope to do follow up work with patients to reveal whether MBCT can also help reduce the risk of relapse. The Oxford team are currently carrying out a larger study that will compare MBCT with a group form of cognitive therapy to pinpoint which elements of meditation or talking therapies can help which people.

Professor Williams, who developed the treatment and led this study, said: ‘We are on the brink of discovering really important things about how people can learn to stay well after depression. Our aim is to help people to find long-term freedom from the daily battle with their moods.’

U.S. spends $9 billion on child mental illness

WASHINGTON (Reuters) – April 22, 2009 – Trchild-mental illnesseating depression and other mental disorders in U.S. children cost $8.9 billion in 2006, making mental illness the most expensive condition to treat in childhood, U.S. government researchers reported on Wednesday.

An estimated 4.6 million children were treated for mental disorders in 2006 at an average cost of $1,931 per child, the Agency for Healthcare Research and Quality reported.

 But more children were treated for asthma than any other disease or injury, the AHRQ found. It said nearly 13 million children were treated for asthma in 2006 at an average cost of $621 for a total of $8 billion.

 Fractures, sprains, burns, and other physical injuries from accidents or violence sent 7 million children to doctors or clinics at a cost of $658 per child or $6.1 billion, the survey found.

My Sweet Emma

Emma with her pink winter coat waiting for her walk

What do you do when your dog of age 16 passes away?  Do you get another one right away?  Is that taking the memory away from the other dog?  What to do.  My little toy poodle, Casey died in November 2008 of old age – it was a truly distressing time.  I was adamant with my husband “no more dogs”, and then thought, there could be a dog out there waiting to be adopted.  Here’s my story:

Emma and I met for the first time on December 09, 2008.  I was to meet her at her foster mum’s home, for she had been living there for the last 1 ½ months. 

Emma scurried to door to greet my mom and I, then rapidly ran back to her doggie bed.  She was ever so adorable, yet looked ever so frightened also.  But what was I to expect, I knew there could be problems – Emma was rescued from a Puppy Mill.

I shed tears while hearing of Emma’s past, or what they knew of it.  The rescue organization said that when she arrived she like a “block of salt”.  No movement/no expression.  Just sat there.  Also she was termed a “dump dog”.   The dogs unable to breed due to age are gathered up, taken to the “garbage dump” and shot.  Some dogs escape, and my little Emma was one of them. 

These unfortunate dogs from puppy mills didn’t ask to be born.  Into a life of living in undersized cages for all of their lives and bred every time they come into heat from six months of age, twice a year until they are too old and of no use.

It’s a life of freezing in winter and surviving from the heat of summer.  Never a toy,  a tender touch, a friendly voice,  soft bed or treat.  Just behind bars all day; in a prison.

I adopted Emma with no question, but still in the back of my mind thinking “am I taking on too much?”  But no, my mind was made up to adopt a dog and not go through a breeder, plus this was my mission, to give her a permanent home instead of a prison where she survived for her whole 6 years.  I wanted her to experience a soft bed, toys, her own dog dish, someone speaking lovingly to her, and running in an off-leash dog park.

It’s been almost 6 months, and Emma is the sweetest, funniest dog you could meet.  I love this dog to bits.  She loves shoes, doesn’t chew them, for that matter never chews anything, but gathers 4 or 5 of my shoes and carries them to the couch.   When I arrive home from work, Emma’s at the door with the tail wagging and the shoes are on the couch!   She was also very well house-trained, as she infrequently does her business on the floor.  When she was new to my home, she would cower when I came near, but she is now pretty much attached to me, following me and loves to snuggle up against me while watching TV.  Only problem:  Doesn’t care much for my hubby, a little growl here and there.  We heard that men operated the mills and that’s probably why they don’t favor males.  We will have to give it some time.

I love my little doggie.  They said she was a “Schnoodle”  (Schnauzer + Poodle), but I think she is more , a bit Schnauzer + Terrier.  Maybe just a Heinz 57.  She weighs almost 16 lbs.

The foster families that these mill dogs go to before adoption do a fantastic job.

FYI:   99.9% of puppies in pet stores come from PUPPY MILLS and there is always a danger that these puppies have health problems.

Death Certificates Incomplete for Suicide Victims

FRIDAY, April 17 (HealthDay News) — About half of those who commit suicide have been diagnosed with a mental disorder.

But fewer than 10 percent of their death certificates list mental disorder as a contributing factor, a new study shows.

 Incomplete death certificates make it more difficult for health-care policymakers to create prevention strategies, said lead researcher Ian Rockett, a professor of epidemiology and associate chairman of the West Virginia University Department of Community Medicine.

“Death certificates are vital to an understanding of suicide, because they provide frontline data in terms of suicide surveillance,” Rockett said. “We need detailed and accurate information to help get our high suicide rates down. … We can’t track this when reporting is casual, sloppy or nonexistent.”

 The study was published in the online British medical journal BMC Psychiatry.

Suicide is the 11th leading cause of death in the United States, according to the National Institute of Mental Heath. Estimates are that 25 people attempt suicide for every one who carries out the act. Suicide outranks homicide as a cause of death.

Incomplete death certificates were the most common among blacks and Hispanics, the study found.

 Researchers analyzed data from more than 140,000 death certificates listing suicide from 1999 to 2003 that were released by the National Center for Health Statistics.

 They found blacks and Hispanics are much less likely to have depression or other health problems recorded on their death certificates. The gap is largest among males, with white males twice as likely as their minority counterparts to have health problems at the time of their death listed.

Addiction Drug May Help Ease Fibromyalgia

FRIDAY, April 17 (HealthDay News) — Low doses of an inexpensive drug called naltrexone — already used for years to treat drug addiction — helped reduce pain and fatigue in women with the painful disorder fibromyalgia, a new study has found.

“Physicians have been using this off-label for a while,” said study co-author Jarred Younger, an instructor in anesthesia and pain medicine at Stanford University School of Medicine. The findings were published online April 17 in the journal Pain Medicine.

 Fibromyalgia is a chronic ailment, marked by musculoskeletal pain and sensitivity to being touched. Some experts say it may affect up to 4 percent of the population.

 Three prescription drugs are also on the market to treat fibromyalgia, Younger said. But, he added, “the three drugs don’t solve the problem for everyone. Some don’t respond to any of these drugs.”

 Younger said he got the idea to study naltrexone after hearing that some other doctors had success with it and after hearing from some members of fibromyalgia support groups that it had worked for them.

 While the results of the small study look promising, Younger said it’s too early to recommend the drug until more research is in.

 In the study, he gave all 10 women a handheld computer and told them to enter daily reports of pain and other symptoms, describing them all on a scale of not bad to worst. The women were taken off their current fibromyalgia medication, then began to take placebo for two weeks (although they did not know it was placebo). Next they took naltrexone for 8 weeks. They then went through a two-week ”washout” period.

 The researchers then evaluated their symptoms. “The drug reduced symptoms by 30 percent compared to placebo,” Younger said. It was a statistically significant difference, he said.

 That was an overall result, and the drug worked better for some than others. “Six out of the 10 were strong respondents, with at least a 50 percent reduction in symptoms,” Younger said. It didn’t work for all 10 women, he said, and some did not respond at all.

Naltrexone also seemed to ease certain symptoms more than others. “The drug helped daily pain — the higher levels of pain, fatigue and stress,” Younger said.

 One symptom that did not typically improve was “fibro fog,” the foggy thinking associated with the disorder, sleep quality, headaches, gastrointestinal problems and sadness.

Exactly how the drug works is not known for sure, Younger said. One possibility is that naltrexone quiets down a hyperactive immune system, he said.

 Younger is continuing the research, and if the good results seen here bear out, naltrexone may be a good alternative for some patients. “It’s a small dose, and we saw very few side effects,” he said. The most typical was vivid dreaming.

Naltrexone has another point in its favor: cost. Doses of the drug, which must be gotten from special “compounding” pharmacies, total about $40 a month, Younger said.

 Another expert called the study “fascinating.”

 “I was pleased to see that they had such a nice response to the therapy,” said Dr. Patrick Wood, a family medicine physician with a specialty practice in fibromyalgia in Renton, Wash. He serves as medical adviser for the National Fibromyalgia Association.

 The study was small, he said, but scientifically sound. If more research is promising, naltrexone may eventually be a competitor to higher-priced fibromyalgia drugs now on the market, Wood said.

Antidepressants underused in the elderly: study

pills4

NEW YORK (Reuters Health) – April 16, 2009 – The results of a postmortem toxicology study indicate that elderly people who commit suicide usually do not have antidepressant medications in their systems at the time of death.

 Antidepressants were found in less than 1 in 4 victims overall, and in even fewer of those in the oldest age group, 85 years and older.

 “Assuming that many of the suicide victims had clinically treatable depression, these findings implicate problems in the delivery of specific antidepressant pharmacologic treatment to the ‘old-old’,” Dr. Robert C. Abrams, from Weill Cornell Medical College, New York, and colleagues conclude in a report in the Journal of Clinical Psychiatry.

 Their findings are based on a study of 255 suicide victims from New York City who were at least 65 years of age at the time of their death between 2001 and 2004.

 Toxicology results available for 162 victims revealed the presence of antidepressant medication in only about 23 percent of cases.

 By age group, rates of antidepressant detection were 22.0 percent in subjects 65 to 74 years of age, 26.8 percent in those 75 to 84 years, and just 16.7 percent in those 85 years and older.

 There was some evidence that many had been using anti-anxiety drugs, hypnotics and painkillers in lieu of antidepressants.
