How Safe is Bariatric Surgery?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

According to some reports, bariatric surgery is now the second most common abdominal surgical procedure performed in the US.
However, despite the well-documented beneficial outcomes, critics continue to question the safety of this treatment option for severe obesity. There is also oft-cited concern about the quality of treatment provided across centres.
These questions were now addressed in [...]... Read more »

Snapshots of magnetic fields

by Joerg Heber in All That Matters

In the absence of GPS, a compass is the best option to find your way around. However, although the earth’s magnetic field is a great way to find your own position, doing the reverse, measuring magnetic fields with a high accuracy — on an atomic scale — remains a challenge. Sure, there are electron microscopes, which are [...]... Read more »

A surprising connection between the munchies and obesity

by Becky in It Takes 30

I’m not normally a fan of research that claims to prove that weight gain is anything other than a result of eating too many, and burning too few, calories; it seems too much like wishful thinking.  But I have to say that the story around gut microbiota being involved in obesity has been getting interesting.  [...]...

Coloured hearing in Williams syndrome

by Kevin Mitchell in Wiring the Brain

The idea that our genes can affect many of the traits that define us as individuals, including our personality, intelligence, talents and interests is one that some people find hard to accept. That this is the case is very clearly and dramatically demonstrated, however, by a number of genetic conditions, which have characteristic profiles of psychological traits. Genetic effects include influences on perception, sometimes quite profound, and other times remarkably selective. A recent study su........ Read more »

Paucis Verbis card: TIMI risk score

by Michelle Lin in Academic Life In Emergency Medicine

How do you risk-stratify undifferentiated chest pain patients in the Emergency Department? There are a multitude of causes for chest pain. We are always taught to think of the 5 big life-threats: ACS, PE, aortic dissection, tension pneumothorax, and pericardial tamponade.So how do YOU risk-stratify your patients for unstable angina (UA) and non-ST elevation myocardial infarction (NSTEMI)? STEMI's are usually obvious. UA and NSTEMIs -- not so much.Fortunately a 2000 JAMA article and a followup Ac........ Read more »

Chosen genes of the Chosen People

Last spring two very thorough papers came out which surveyed the genetic landscape of the Jewish people (my posts, Genetics & the Jews it’s still complicated, Genetics & the Jews).

Feeling clean makes us harsher moral judges

by BPS Research Digest in BPS Research Digest

As the dirt and germs are wiped away, we're left feeling not just bodily but also morally cleansed - a kind of metaphorical virtuosity that leads us to judge others more harshly. That's according to Chen-Bo Zhong's team, who invited 58 undergrads to a lab filled with spotless new equipment. Half the students were asked to clean their hands with an antiseptic wipe so as not to soil the shiny surfaces. Afterwards all the students rated the morality of six societal issues including pornography and ........ Read more »

Effect of climate change on human morbidity and mortality and sea levels

by Sarah Stephen in An ecological oratorio

Climate change has been resulting in quite a many detrimental manifestations which tend to have a domino effect: fluctuations in temperature and precipitation (resulting in climate variability), as well as extreme manifestations such as drought, storms, rise in sea levels, and frequent severe weather events.Consider the research by Grinsted et al (2009) who used a ‘physically plausible four parameter linear response equation’ to relate nearly 2,000 years of global temperatures and sea level.........

Lose the ears, but keep the neurons

by Zen Faulkes in NeuroDojo

Bigger. Better.

When thinking about the evolution of nervous systems, there is sometimes a tendency to think of a sort of manifest destiny of nervous systems. It’s part of a larger tendency to see everything in evolution as part of a “march of progress,” but somehow, I think there’s a greater tendency to think about neural evolution as a tale of ever increasing complexity.

Examples of simplification are nice examples of exceptions. Vestigial organs have always been seen as powerful exa........ Read more »

Tadpole Ripples

by Journal Watch Online in Journal Watch Online

Tadpoles can leave ripples in a stream – even when they are gone. With a deadly fungus causing catastrophic declines in tropical frogs, many streams are losing their tadpoles. The loss of the wrigglers can subtly but significantly reorder stream ecosystems, find researchers who are studying the ecological aftermath in Panama.
The chytrid fungus has […] Read More »... Read more »

Future Imagining And Episodic Memory

by Maria P. in noustuff

Neuroimaging and lesion studies suggest that imagining the future (i.e. envision future personal experiences) is strongly connected with retrospective memory (i.e. remembering past experiences). Two recent papers published on Neuropsychologia investigated the relationship of retrospective memory and future imagining, as well as their common neural correlates. Kwan, Carson, Addis, and Rosenbaum (2010) report the case [...]... Read more »
