Shoulder pain: a randomised trial shows that "subacromial decompression" surgery may be no more effective than placebo.

Arthroscopic subacromial decompression for subacromial shoulder pain (CSAW): a multicentre, pragmatic, parallel group, placebo-controlled, three-group, randomised surgical trial

Beard, David JAhrens, Philip et al.
The Lancet

Summary


Background

Arthroscopic sub-acromial decompression (decompressing the sub-acromial space by removing bone spurs and soft tissue arthroscopically) is a common surgery for subacromial shoulder pain, but its effectiveness is uncertain. We did a study to assess its effectiveness and to investigate the mechanism for surgical decompression.







Interpretation

Surgical groups had better outcomes for shoulder pain and function compared with no treatment but this difference was not clinically important. Additionally, surgical decompression appeared to offer no extra benefit over arthroscopy only. The difference between the surgical groups and no treatment might be the result of, for instance, a placebo effect or postoperative physiotherapy. The findings question the value of this operation for these indications, and this should be communicated to patients during the shared treatment decision-making process.

Raw milk cheese linked to two listeria deaths in Northeast US

http://www.bbc.com/news/world-us-canada-39229635


Two people have died and four more have fallen ill following an outbreak of listeria linked to recalled cheese in several eastern US states.
Officials say it was probably caused by a soft raw milk cheese called Ouleout from Vulto Creamery in New York state.
The cheese was stocked by a Whole Foods shop in Fairfield, Connecticut, and may also have been available in specialised cheese shops.
The creamery recalled several soft cheeses on Tuesday.
Six cases of listeria have been recorded in Connecticut and Vermont, where the deaths occurred, as well as in New York and Florida.

Scientists Say the Clock of Aging May Be Reversible

Scientists Say the Clock of Aging May Be Reversible

Scientists reveal that they have used a technique, now 10-years old, that had been shown to reset cells to stem cell state to rejuvenate aged cells. Original research using this technique had led to disastrous consequences with some test animals dying due to cells loosing their identity (stem cells can become any cell in the body) and others due to cancer (cancer is essentially rapid, runaway cell growth). 

Since those disastrous tests scientists have realized that cells don't use the full suite of steps in becoming stems cells but rather use a subset to prime cells for regrowth (and rejuvenation) without loosing their identity.

At the Salk Institute in La Jolla, Calif., scientists are trying to get time to run backward.

Biological time, that is. In the first attempt to reverse aging by reprogramming the genome, they have rejuvenated the organs of mice and lengthened their life spans by 30 percent. ...

How to Become a ‘Superager’

How to Become a ‘Superager’

For people who have mentally age well, their brains show thicker regions in specific areas relative to those suffering from classic aging signs. But - drop notions of this being the outer regions of the brain which are classically presented as the region of higher function. This "triune brain" frame is incorrect and has been for awhile within brain research. Rather, it is in the more inner regions where the brain works to bridge the analytical with the emotional that are shown to be enhanced. In the end the researchers do not know what it is that leads to this outcome but nonetheless they have recommendations. They state that people should work those regions of the brain through strenuous work. Be that analytical, physical or emotional work. The researchers say pushing oneself into those areas that are challenging and difficult (to a point) are what leads to benefit. In other words - don't take the easy path. (Is this our underlying puritan meme coming out? Or an actual benefit... ?)

From the New York Times by LISA FELDMAN BARRETT DEC. 31, 2016
Think about the people in your life who are 65 or older. Some of them are experiencing the usual mental difficulties of old age, like forgetfulness or a dwindling attention span. Yet others somehow manage to remain mentally sharp. My father-in-law, a retired doctor, is 83 and he still edits books and runs several medical websites.

Why do some older people remain mentally nimble while others decline? “Superagers” (a term coined by the neurologist Marsel Mesulam) are those whose memory and attention isn’t merely above average for their age, but is actually on par with healthy, active 25-year-olds. My colleagues and I at Massachusetts General Hospital recently studied superagers to understand what made them tick.

Taking Fish Oil During Pregnancy Is Found to Lower Child’s Asthma Risk

Taking Fish Oil During Pregnancy Is Found to Lower Child’s Asthma Risk

Women who took fish oil during the last three months of pregnancy significantly lowered the risk that their children would develop asthma, a study in Denmark has found.
Among children whose mothers took fish-oil capsules, 16.9 percent had asthma by age 3, compared with 23.7 percent whose mothers were given placebos. The difference, nearly 7 percentage points, translates to a risk reduction of about 31 percent.
But in the study released on Wednesday, the researchers say they are not ready to recommend that pregnant women routinely take fish oil. Although the study found no adverse effects in the mothers or babies, the doses were high, 2.4 grams per day — 15 to 20 times what most Americans consume from foods.

A Return to Health (Points)




Yes - it is true that I have been crazy busy for the past six years first entering a new career that had a ton of travel and then building that career with ever increasing travel while also (at least trying) to maintain connection with family. Overall I think largely successful. But my interest in health is still here as is my interest in science and the scientific method. So I think it is time to revive the Health Points blog. I will attempt to post regularly (though I always get a little intimidated about writing) with a post per fortnight being the goal. There - done it. I've made a goal.

I have to admit that one of the reasons I want to return to this is my desire to write more. Somehow in my field of expertise (integration of physical and social sciences to promote sustainable development) I find writing to be more challenging. This is because of the level of importance I put on it. This blog, though valuable to me, is safer for me to post to since I make no claims to be a health expert. This fo course does not mean that I cannot learn, research and otherwise connect the dots. Seriously - there is not that big a divide between "everyday people" and many "experts". It is simply a matter of who is tracking what - this is good to remember. 

Goals by the way are the number one way to promote behavior change in oneself (or anyone - as long as they "own" the goal). Though the latest craze among the "in the know" set talk about how we humans do not possess "free will" (see SciAm or io9) this belief (though rooted in research) emerges only from an understanding of a small window in the choice-behavior cycle. In short - since our neurons fire before we take an action, even our seemingly random "choice" was predetermined (by our brain). But we do have a way to retrain our brains (called making new habits) and with that it is my claim that we regain "free will" and can regain control of our lives.

So quit those cigarettes, quit eating those chocolate chip cookies every day (yes, that one is directed at me) and get out and walk, run, or otherwise have fun. Set the goals, perhaps fail to make them sometimes (perhaps inevitable?), love yourself anyway, and keep moving forward. You will make change - that is assured.

In addition to writing more I hope to update the look and feel of the site. Please at any time - feel free to add a comment or otherwise contact me if you like or don't like what you read or have suggestions on topics you'd like me to research, cover or direct you to.

Thanks all and happy health goal setting to us all
