Because He Is The One

by Mark Lasbury in As Many Exceptions As Rules

Swatting a fly is hard. They always seem to know you’re coming, and even if you do surprise them, they often avoid your assassination attempts. New research is showing how they do it. A 2014 paper indicates that animals with faster metabolic rates actually process information and react quicker than larger animals. This, along with recent data showing how flies can jump away from a visual stimulus before taking flight and how they can coordinate a 0.03 second banking turn with incoming visu........ Read more »

How Stress Promotes Atherosclerosis

by Agnese Mariotti in United Academics

There is evidence that chronic stress increases the risk of atherosclerosis, but no mechanism linking the two phenomena has been demonstrated so far. Since stressful emotional states can affect the function of the immune system, Heidt and colleagues of the Massachusetts General Hospital hypothesized that stress increases the activity of inflammatory cells in the plaques facilitating their rupture, as you can read in their recently published article....

ADHD in DSM-5: what did you think would happen?

by Paul Whiteley in Questioning Answers

"Our results, combined with previous findings, suggest a 27% increase in the expected prevalence of ADHD [attention-deficit hyperactivity disorder] among young adults, comparing DSM-IV to DSM-5 criteria". So said the paper by Matte and colleagues [1] who as part of their study looked at "the prevalence of ADHD according to DSM-5 criteria".Europa @ Wikipedia The changes to the diagnosis of ADHD in DSM-5 can be seen here. The main difference between DSM-IV and DSM-5 diagnosis s........ Read more »

Dextrose 10% in the Treatment of Out-of-Hospital Hypoglycemia

by Rogue Medic in Rogue Medic

Is 50% dextrose as good as 10% dextrose for treating symptomatic hypoglycemia?

If the patient is disoriented, but becomes oriented before the full dose of dextrose is given, is it appropriate to continue to treat the patient as if the patient were still disoriented? If your protocols require you to keep giving dextrose, do the same protocols require you to keep giving opioids after the pain is relieved? Is there really any difference?

50% dextrose has problems.... Read more »

Hobby Lobby and the War on Race and Women

by Gabriel in Lunatic Laboratories

There is a war going on and it's not on foreign soil. This war is the fight for the status quo, a war where you are only worth your skin color, a war where you are only worth as much as your gender. This war is all around us, we see it everyday, yet we let it quietly pass us by. We do this because, in all actuality, we are losing this war. I don't blame you if you don't believe me, you shouldn't.[…]... Read more »

Family processes and trajectory in autism

by Paul Whiteley in Questioning Answers

The paper by Woodman and colleagues [1] looking at trajectory and autism in adolescents and adults is the source material for today's post (another micropost). Concluding that: "Overall, autism symptoms and maladaptive behaviors were observed to improve over the study period" of about 8 years, the authors also reported that "greater improvements were associated with higher levels of maternal praise (based on maternal speech samples) and higher quality mother-child relationships". If I remember c........ Read more »

We can Build it Better: The First Artificial Cell Network

by Gabriel in Lunatic Laboratories

How does the old saying go? Imitation, is the sincerest form of flattery? Well that is what we’ve been trying to do for a very long time, but mimicking the intricate networks and dynamic interactions that are inherent to living cells is difficult to achieve outside the cell. Unfortunately despite all our intelligence nature has had the upper hand on us for a long time. That has not changed… until now that is.[…]... Read more »

Guidelines for Treatment of Problem Gambling

by William Yates, M.D. in Brain Posts

Despite the prevalence and impact of problem gambling, few summaries or guidelines address treatment.Searching the guideline.gov website shows no recent additions to the guideline literature.A guideline was published by the Singapore Ministry of Health in 2011. This guideline is still relevant and highlights some of the key elements of a problem gambling treatment program.I will summarize some of these key elements from this source titled: "Management of gambling disorders".  In their summa........

A mosaic vaccine that could potentially protect from different ebola strains

Disclaimer: The mosaic vaccine paper discussed in this article is from my own group and overlaps with some of the research I do. I'm sure you've been following the latest news about the Ebola virus outbreak in Africa."The Ebola outbreak in West Africa is the world's deadliest to date and the World Health Organization has declared an international health emergency as more than 1,000 people have died of the virus in Guinea, Liberia, Sierra Leone and Nigeria this year."

The epidemiology of autism spectrum disorders

by Paul Whiteley in Questioning Answers

A very short post for readers to ponder based on the paper by Amanda Baxter and colleagues [1] who talked about the global epidemiology of the autism spectrum disorders (ASDs)."In 2010 there were an estimated 52 million cases of ASDs, equating to a prevalence of 7.6 per 1000 or one in 132 persons".Aside from emphasising the word 'estimated' (I highlighted that), be prepared to see the Baxter paper and that quote cited quite a bit in the peer-reviewed literature in times to come.----------[1........

In Defense of Eating Junk Food in Eating Disorder Treatment

by Shirley in Science of Eating Disorders


Should eating disorder patients be introduced to “junk food” or “hyper-palatable” foods during treatment? A few days ago, I stumbled across a blog post where Dr. Julie O’Toole, Founder and Director of the Kartini Clinic for Disordered Eating, argues against introducing “junk food” during ED treatment. The crux of the argument is that “hyperpalatable foods”—e.g., chips and Cheetos—are not real food and should never be forced or encouraged for anyone, regard........ Read more »

Psychotic experience following childhood neurodevelopmental diagnosis

by Paul Whiteley in Questioning Answers

The paper by Golam Khandaker and colleagues [1] suggesting a higher risk of psychotic episodes (PEs) in early adolescence among those with a diagnosed childhood neurodevelopmental disorder (ND) makes for some interesting reading. Detailing several diagnoses as falling under the banner of neurodevelopmental disorder (autism spectrum, dyslexia, dyspraxia, dysgraphia, dysorthographia, dyscalculia), researchers concluded that: "The risk of PEs was higher in those with, compared with those witho........

Dying To Make Us Laugh

by Mark E. Lasbury in The 'Scope

Robin William’s suicide was a tragic, but all too familiar happening amongst humorists of this period. New research is showing that comedians, performers in the arts, and even people with better senses of humor are prone to more health problems as adults. Depression , cardiovascular, pulmonary and stress related problem are not uncommon in comedians, and even children and adults that have better sense of humor are susceptible to obesity and cardiovascular disease.

The irony is that t........ Read more »

Getting High On Life

by Mark Lasbury in As Many Exceptions As Rules

Living organisms can survive and thrive in all kinds of rough environments. This would include the edges of space. There are bird species that can fly at almost 40,000 ft., as high as the highest clouds. New research is showing just how the bar headed goose is able to fly when the air is thin and the oxygen is scarce. But more impressive are the bacteria. They can actually live their whole lives in the air, dividing and growing nearly 25 miles (41 km) above the surface of the Earth. A study from........ Read more »

HIV Vaccine One Step Closer to Reality

by Gabriel in Lunatic Laboratories

The war on HIV, that tricky little guy has avoided every thing we could throw at it in a broad sense. Sure a few people here and there get lucky, but we have yet to actually make any sort of we're going to kick your ass headway [don't worry it's the technical term for it]. That is hopefully going to change with a new scientific discovery that has enormous implications for HIV vaccine development. Researchers have uncovered novel properties of special HIV antibodies that promise to........ Read more »
