Could you be almost depressed?

Consider whether the following questions describe you or someone you love:

Are having trouble enjoying things in life that used to be fun?

Do you find that you are constantly irritable and overreacting to petty incidents? Are you are regularly finding excuses to avoid spending time with friends or family?

Does it seem like you’re “just going through the motions” and barely getting through the day? Do you feel overstressed and believe there is no way you can ever catch up with what you have to do?

If any of these questions rings true, you may be almost depressed. And you are not alone. Research suggests that as many as 12 million people in the United States may be suffering from low-grade depression symptoms that are not severe enough to warrant clinical treatment.

Almost depression is not a mental disorder. It is a state of low mood that can leave you exhausted and de-energized, keeping you from savoring life and working at your peak performance level. It is a gray area of mood problems that lies on a continuum between the ups and downs of normal mood, and full-blown major depression.

(You may wonder how you can tell if your mood symptoms put you in the almost depressed range, or if they are serious enough to be considered major depression. If you are thinking about death or suicide, have lost a significant amount of weight because of appetite changes, or have feelings of hopelessness or extreme guilt, or if you believe your symptoms may be severe enough possibly to warrant a diagnosis of major depression, please contact a mental health professional.)

At Harvard Medical School, we have been investigating the effects that almost depression and other subclinical conditions can have on an individual’s quality of life. People who are almost depressed report a number of issues, including lower job satisfaction, lower satisfaction with their marriage and other personal relationships, more anxiety issues, less control over their lives and lower overall well-being than people who do not fall into the almost depressed range.

In fact, on some of these measures, people who are almost depressed report feeling worse off than people who actually fall into the clinically depressed range. Clearly, even though almost depression does not rise to the level of a diagnosable mental disorder, it is nevertheless associated with a substantial amount of distress and suffering.

There is also another more serious problem: Research indicates about 75% of cases of low-grade depression will devolve into full-blown major depression if they are not recognized and arrested.

Major depression is a deadly disorder. People who are depressed have four times the risk of heart disease and almost six times the risk of dying after a cardiac event than people who are not depressed.

People who are depressed also have between nine and 16 times the risk for suicide than people who are not depressed.

It is therefore vitally important to recognize the symptoms of almost depression in yourself and your loved ones, and to take steps to reduce the suffering it causes.

There are a number of things you can do to combat almost depression that have been shown to be effective in randomized clinical trials (the gold standard of treatment testing). Here is a list of some these “evidence-based” steps:

Make sure you are getting enough exercise. The minimum amount for treating depression is 30 minutes of continuous aerobic exercise (70% to 85% of maximum heart rate) plus a 10-minute warm-up and cool-down period three times a week.

Integrate activities you have found pleasurable in the past into your weekly calendar. Even if you feel that you no longer enjoy them, such activities will increase the activation of the pleasure centers in your brain. As your symptoms resolve, you will regain pleasurable feelings.

Use creative outlets to express your negative feelings. You don’t need experience or talent to express yourself creatively, so paint, write or play music. Expressive creative work reduces depressive symptoms.

Manage your stress level. Stress has negative effects on both the brain and the body and can be a major source of depressive symptoms.

Challenge the way you think. Our moods are dependent not upon what happens to us in our lives, but in how we interpret what happens. Changing your interpretation has been shown to reduce depressive symptoms.

Increase your level of mindfulness. Mindfulness training and practice is an effective way to keep depression at bay.

Reduce the power you give to your “inner critic.” Often the negative and critical things we say to ourselves lead to feelings of depression and powerlessness.

Increase your social support circle. Having a strong social support system is a known protective factor against depression.

Improve your self-care. Poor nutrition and poor sleep habits can augment feelings of depression. In some cases, specific nutritional supplements can work wonders.

The steps that work for you will be dependent upon your specific signs and symptoms, the severity of your symptoms and your personality. If one step doesn’t work, do not give up.

There are many pathways to wellness, and with patience you will find the way that works for you.

You don’t have to be almost depressed. You can take charge of your symptoms and make your way out of the gray shadows and into the full light of good mental health.

How Sweden’s New Text Message Plan Is Saving Cardiac Arrest Victims

By
October 28th, 2013

Trained volunteers receive notifications in order to shave crucial minutes off emergency response times.

By using text messages, the city of Stockholm, Sweden is getting emergency responders to cardiac arrest victims faster.

Here’s how it works. Volunteers who are trained in CPR are added to a network called SMSlivräddare, (or SMSLifesaver). When a resident dials 112 (the equivalent of 911 in the states), a text message is sent to all CPR volunteers who are within 500 meters of the person needing emergency care. This way, a volunteer may get to the patient faster than an ambulance.

The likelihood of survival from cardiac arrest drops 10% for every minute it takes first responders to arrive. CPR administered by bystanders has been found to significantly increase the likelihood of survival, but not everyone feels comfortable doing it, or even knows how.

SMSlifesavers is run by Stockholm South General Hospital and the Karolinska Institute and currently has 9,600 registered volunteers. According to Quartz, there are about 200,000 Swedes who have undergone CPR training and could participate.

SMSlifesavers’ spokesperson, Dr. Mårten Rosenqvist, told Quartz that traditional ambulance services have trouble reaching cardiac arrest victims in teh Stockholm area due to lack of vehicles, traffic and other patient duties.

New Definition of “Full-Term” Pregnancy Presents Other Problems

By

By @ProfEmilyOsterOct. 22, 2013

Big news for women who are 38 weeks pregnant: you are no longer considered “full term.” The American College of Obstetricians and Gynecologists (ACOG) announced today that they would introduce a new classification system for the end of pregnancy.  Previously women who were 37 to 41 weeks pregnant were all considered “Full Term” and women 42+ weeks “Post-term”.  The new classification system calls for four groups:  “Early Term” (37-38 weeks), “Full Term” (39-40 weeks), “Late Term” (41 weeks) and “Post-term” (42+weeks).

I know, that’s a lot of terms. But the big change here is to separate out the 37 to 38 week period and acknowledge that, for most babies, this isn’t the ideal time to be born. Evidence has been piling up that babies born in this period do worse than babies born at 39 or 40 weeks. One very recent paper shows babies at 37 to 38 weeks are more likely than those born later to need time in the NICU, mechanical ventilation and IV fluids. But as induction and scheduled C-sections have become more common, the share of babies born at 37 or 38 weeks has risen from 17% in 1983 to 27% in 2009. Many of these deliveries are elective and driven, at least in part, by the perception by women (or their doctors) that things are ready to go at 37 weeks. The push to reduce these early-term deliveries has been going on for years.

This change in wording could make a big difference in practice. Early term births are expensive because of their added complications and by explicitly distinguishing them it makes it easier for insurers to refuse to cover elective births in this period. The problem, however, with having a strict guideline like this is that sometimes people start to treat it the cutoff itself as meaningful.

It is worth reflecting back on why this change is even necessary.  The idea that 37 weeks is “full term” is intended to be descriptive.  As pregnancy moves forward, the baby becomes more developed.  Among the last organs to develop are the lungs, and usually this happens by 37 weeks, so calling 37 weeks “full term” is simply an acknowledgement of this. But women, and their doctors, can start to think that when you move from 36 weeks 7 days pregnant to 37 weeks 0 days pregnant there is a magic switch which means your baby is ready.  This is obviously not the case.

This is illustrative of a broader issue, in medicine and elsewhere, with any kind of sharp rule-like cutoff.  In one example, researchers have shown that as a result of drawing the cutoff for very low birth weight at 1500 grams, babies born right below 1500 grams of weight actually have better outcomes than those right above, because they are given extra treatment.  Again, there is nothing biologically special about 1500 versus 1499.  The cutoff is descriptive, and when it’s treated as a rule, odd things happen. The same issues come up in finance, closer to my own field, when looking at lenders who used sharp cutoffs in credit scores in deciding who to lend to.  There is nothing special about a credit score of 620 compared to 619, and when you treat it like there is, you can get into trouble.

The worry, of course, to return to the babies, is that what is happening here is we are replacing one rule with another. The new guidelines fix one issue, but could lead doctors (in theory) to be too cautious about delivery in 37 or 38 weeks when medically warranted. It could also lead them to be too gung-ho about delivery as soon as you hit 39 weeks. The best case would be if women and their doctors took these terms as they are intended— as descriptive guidelines, not rules—and got better about letting nature take its course unless there is a medical reason not to.  If that happens, this truly will be a major change, and not just for the women at 38 weeks.

Deep-Voiced Men Make Bad Mates: Study

By

Men with deeper voices have an advantage in attracting women, but mostly if they’re looking for a fling, new research suggests.

Researchers at at McMaster University in Ontario, Canada have previously reported on the link between the depth of a guy’s voice and his attractiveness to women. They also figured that guys with lower voices, and hence probably more testosterone, were more likely to cheat (they were right). What they couldn’t work out was why women preferred the men who were probably going to be cads. So they went back to the audiotape.

In the new study — which may also provide some insight into why Isaac Hayes songs are forever a popular choice for the boudoir — researchers had women listen to men’s voices and asked them first if they thought the speaker was a faithful sort of guy. Then they were asked if they fancied the owner of the voice for a long or short-term relationship. The deep-voiced men were chosen more often for short term relationships, but mostly by certain sorts of women—those who had already expressed a belief that a bass voice often led to fishy behavior.

“Differences in the strength of women’s preferences were accounted for by whether or not they thought the voices belonged to a cheater,” says Jillian O’Connor, a postdoctoral fellow in the Department of Psychology, Neuroscience and Behaviour at McMaster, who was this study’s (and the prior one’s)  lead author. “Women who thought that men with lower pitched voices were cheaters liked them for short-term flings.”  The scientists defined “short-term relationship” more towards the one-night-stand than the May to December fling.

The women who didn’t associate a deep pitch with infidelity tended to prefer those guys for long term relationships. The authors surmised that some women have come to adaptively understand that more macho guys are more likely to cheat — and have thus learned to avoid macho-sounding guys for serious life partnering.

For deep-voiced males, fear not. The study was pretty small, just 87 women, and it didn’t use actual tones. The voices the women heard came from the same guy with his pitch digitally deepened or heightened. Which means the findings probably aren’t conclusive enough to cross off any baritones from anybody’s list of eligible bachelors, even if biology were destiny.

Study: Predicting Whether a Partner Will Cheat Could Be Gender-Specific

The lure for a deep voice for females may have something to do with the woman’s biology too. “Some of my other research has found that women who have more attractive faces have stronger preferences for lower pitched men’s voices,” says O’Connor. “But that was not examined in this study.” Looks like men are not the only ones who respond to siren songs.

Study: Breast Milk Sold Online Can Get Your Baby Sick

By

Donated or sold breast milk contains bacteria and sometimes salmonella

A small marketplace for breast milk has sprouted online, but a study published Monday confirms what health professionals suspected: Internet breast milk is often tainted.

The study, published in Journal of Pediatrics, found that breast milk donated or sold on two popular websites was often contaminated with high levels of bacteria that could make a child sick, including salmonella. Sixty-four percent of the samples were contaminated with staph, 36 percent with strep and almost 74 percent had so much bacteria that they would have failed the Human Milk Banking Association’s criteria, the Associated Press reports.

Recent research has found that breast milk protects infants from infections, so doctors have been encouraging new mothers to breast-feed rather than use formula. But not all women can do so — couples who have adopted, mothers who have mastectomies and women who simply cannot produce enough milk are forced to rely on donated or purchased breast milk.

Some turn to breast milk banks, where the Human Milk Banking Association screens donors. But banks prioritize premature infants with medical complications, and do not hold enough milk for healthy infants whose mothers simply cannot lactate.

In 2011, there were more than 13,000 postings on the four leading milk-sharing sites, the AP reports.
