Statin Therapy: Rethinking Benefits and Risks
by William Yates, M.D. in Brain Posts
A recent 30-page manuscript provides an exhaustive review of the evidence for the efficacy and safety of statin therapy.The authors of this excellent review provide some context for the relative value of statins.The note that putting 10000 individuals with a history of a vascular event on a statin drug for 5 years would prevent 1,000 subsequent events. This is an example of secondary prevention--preventing another adverse outcome in those already experiencing an adverse event.But the statin drug........ Read more »

How to rebuild a brain
by gdw in FictionalFieldwork
After the stroke The human brain is complicated. Very complicated. And like any piece of complex machinery that relies on the smooth functioning of many components, it’s not immune to malfunction. When a part of the brain doesn’t get proper nutrition through a nice and smooth blood flow, things go awry and a stroke occurs. […]... Read more »

The PROCAMIO Trial – IV Procainamide vs IV Amiodarone for the Acute Treatment of Stable Wide Complex Tachycardia
by Rogue Medic in Rogue Medic
This is a very interesting trial that may surprise the many outspoken amiodarone advocates, but it should not surprise anyone who pays attention to research.
ALPS showed that we should stop giving amiodarone for unwitnessed shockable cardiac arrest. The lead researcher is still trying to spin amiodarone for witnessed shockable cardiac arrest, even though the results do not show improvement in the one outcome that matters – leaving the hospital with a brain that still works.[1],[2],[3]...

Does Flu Vaccination Reduce Dementia Risk?
by William Yates, M.D. in Brain Posts
In my daily review of neuroscience news I ran across an article flu vaccination and dementia risk in heart failure.This study was reported at the 3rd World Congress on Acute Heart Failure by Dr. Ju-Chi Liu from Taipei Medical University.So how might influenza vaccination be related to dementia risk? We do know acute influenza infection reaches the brain causing headache and increasing brain inflammation, at least temporarily. We also know brain inflammation may be involved in the mechanism........ Read more »

Quick Aspirin Use Reduces Stroke Risk in TIA
by William Yates, M.D. in Brain Posts
A free full-text commentary in the Lancet summarizes recent evidence of the benefit of aspirin in stroke prevention.This commentary focused on what is called secondary prevention. Secondary prevention is defined as prevention following events related to the disease in question.So secondary prevention in stroke would be reduction in stroke risk in those who have had a stroke or pre-stroke syndromes such as transient ischemic attacks (TIA).The key take-home message from the commentary by Graeme Ha........

Delirium and Aortic Valve Surgery Outcome
by William Yates, M.D. in Brain Posts
Delirium is an acute confusional state that is common in elderly hospitalized patients.I think of it light a sign of acute brain failure requiring aggressive attentional for detection and treatment of any reversible underlying causes.Delirium in elderly hospitalized patients is a marker for poor outcome in a variety of medical and surgical subjects.A recent study published by a Norwegian team found effects on outcome for delirium following surgical aortic valve replacement. The key findings from........ Read more »

Food to Restore a Heart
by Aurametrix team in Health Technologies
We know that diet, exercise and low-stress life will keep the heart healthy. But sometimes things happen that are beyond our control. Thanks to more coordinated, faster emergency response and improved treatment, heart attacks aren't as deadly as they used to be. But survivors still face a substantial risk of further cardiovascular events. How to restore after a heart attack and prevent another one? What to do besides obvious things such as taking medications, reducing stress, calories, avoidin........ Read more »

Dr. Kudenchuk is Misrepresenting ALPS as 'Significant'
by Rogue Medic in Rogue Medic
This study was very well done, but it was not designed to provide valid information about the effects of amiodarone or lidocaine on witnessed arrests or on EMS Witnessed arrests. Maybe the authors were overconfident.
In resuscitation research, we have abundant evidence that overconfidence is much more common than improvements in outcomes.... Read more »

What do you do when a patient wakes up during CPR?
by Rogue Medic in Rogue Medic
The return of consciousness without the return of a pulse is still rare, but may be more common with our increased focus on high quality chest compressions. There is still no evidence that interrupting chest compressions, for anything other than defibrillation, improves outcomes.
Is this due to the consistency of the machine? Maybe. Maybe not. We do not have enough evidence to draw that conclusion.
Is this growing population really growing? Maybe. Maybe not. We do not have enough evidence ........ Read more »

The secret pharmacological life of the humble avocado
by Rosin Cerate in Rosin Cerate
Guacamole, while delicious, is actually fairly destructive. This is thanks in part to a compound called persin, which is present in the fruit and leaves of the avocado tree (Persea americana). Persin is an acetogenin (a type of polyketide) made via the same biochemical pathways the avocado plant uses to make its delicious fatty acids. In fact, it closely resembles linoleic acid, an essential omega-6 fatty acid.Avocado fruits in their natural setting (Source)For some reason, persin is usuall........ Read more »

Heartbreaking drugs: A Valentine's Day special
by Rosin Cerate in Rosin Cerate
Let's talk about hearts and how they get broken. Literally, with drugs. When we swallow a pill, it's often to help address a problem we're experiencing with a particular body part. An aching head or a sore throat, for example. The pill breaks down in our guts and we absorb the drug into our bloodstream. It travels around our body and eventually ends up at the hurting locale where it works to fix the problem. Unfortunately, sometimes the drug will end up somewhere else and act there to cause an u........ Read more »

Religion linked to reduced levels of stress hormones in young American Blacks
Compared with Whites, Black Americans have high levels of an important stress hormone called cortisol circulating in their bloodstream. No-one really knows why this is, but the differences remain even after you take into account social and psychological factors. It seems likely that simply being black exposes you to a cumulative effect of increased lifetime [Read More...]... Read more »
