Resuscitation characteristics and outcomes in suspected drug overdose-related out-of-hospital cardiac arrest

by Rogue Medic in Rogue Medic

This study is interesting for several reasons.

In a system that claims excellence, the most consistent way to identify the study group is by documentation of a protocol violation - but it is not intended as a study of protocol violations.

This may hint at some benefit from epinephrine (Adrenaline in Commonwealth countries), but that would require some study and we just don't study epinephrine. We only make excuses for not studying epinephrine.

The atropine results suggest that the ........ Read more »

Parental Age and the Rise of Autism Spectrum Disorder

by Alexis Delanoir in How to Paint Your Panda

It has been documented that there has been a rise in Autism Spectrum Disorder (ASD) in the United States, and that a large cause of this is due to redefinition of the disorder in the Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-V) and an increased familiarization among psychiatrists and psychologists; but there is an unexplained portion of the increase. Studies have shown that parental age, namely maternal age can confer a higher risk for ASD. With the rise of paren........ Read more »

UCSF Scientist Discovers Key to Immune System Aging

by beredim in Stem Cells Freak

Emmanuelle Passegué, PhDThere's a good reason people over the age of sixty are not donor candidates for bone marrow transplantation. The immune system ages and weakens with time, making the elderly prone to life-threatening infection and other maladies, and a UC San Francisco research team now has discovered a reason why."We have found the cellular mechanism responsible for the inability of blood-forming cells to maintain blood production over time in an old organism, and have identifi........

THE HETEROGENEITY OF CANCER AND DNA AS A PROGNOSTIC MARKER: THE TRUTH IS IN OUR BLOOD

by Amy Swanston in Antisense Science

Tumours are incredibly heterogeneic- that is that they have different properties including morphology (how they look), metabolism (the processes they use to generate energy), proliferation (how fast they grow, divide and replicate themselves) and potential to metastasise (where a tumour moves to another part of the body). But why is this so?

Many people are under the assumption that a cancer will arise from a single mutation in the DNA, but this is not actually the case. For a cancer to dev........ Read more »

Psychologists investigate a major, ignored reason for our lack of sleep - bedtime procrastination

by BPS Research Digest in BPS Research Digest

Short term, lack of sleep scrambles our mental functioning. Long term, the health consequences can be dire. What's stopping us from getting enough?For many, adequate sleep is elusive because of sleep disorders, including varieties of insomnia. For others there are practical challenges - baby care or night shifts, for example. A new study focuses on another major, yet strangely overlooked, reason - bedtime procrastination. You want to go to bed early. You know you need to get to bed. And yet you ........ Read more »

Restricted and repetitive behaviours disappeared? More optimal outcome and autism

by Paul Whiteley in Questioning Answers

Today I'm bringing to your attention the paper by Eva Troyb and colleagues [1] and the quite dramatic assertion: "Reports of current behavior indicated that RRB's [restricted and repetitive behaviors] had almost totally disappeared in the OO [optimal outcomes] group". RRBs just in case you might not know include quite an array of behaviours, some of which might not be considered 'disabling' such as the presence of certain circumscribed interests. Others, such as an insistence........ Read more »

Scientifically known as Cotylorhiza tuberculata, it is one of the two jellyfish species that resemble a fried egg. The other one is Phacellophora camtschatica. Not surprisingly, it also goes by the same name.They may look tasty, but you probably don't want to have one for breakfast! However, you can have a lot of fun with C. tuberculata. This jellyfish has a ........ Read more »

The Evidence from Skull Measurements

by teofilo in Gambler's House

So far in this series of posts on “tracing the connections” between ancient Pueblo sites like Chaco Canyon and modern Pueblos, I’ve discussed evidence from linguistics and folklore, but of course if the issue is determining which modern groups are physically descended from which ancient ones it’s hard to beat evidence from actual physical remains.
