Prehospital Intravenous Fluid Administration is Associated With Higher Mortality in Trauma Patients – Part III

by Rogue Medic in Rogue Medic

In Part II, I explained the problems with the NTDB claiming that only 49.3% of trauma patients had IV starts documented. While that is a problem, looking at the data on the rest of the "top 5 procedures" makes the documentation failure even more obvious.... Read more »

Signals for Infection

by Lab Rat in Lab Rat

Neisseria meningitidis is a bacteria which lives in the throats of around 30% of the human population. In most cases it causes no problems at all and just exists as a normal part of the throat microbial flora. In some patients however it can start to colonise the bloodstream and brain, leading to cases of septicemia and meningitis which are highly dangerous and can be fatal.The invasion starts with individual bacteria, which adhere to the epithelial cells that cover the inside of the throat. Th........ Read more »

Hot off the press: Clinical practice guideline for ketamine in the ED

by Michelle Lin in Academic Life In Emergency Medicine

A 3 year old girl is brought into the ED with an abscess to her groin. Upon examination it is fluctuant and needs incision and drainage. Next door is a 5 year old boy, who fell off his bed and has an angulated radius fracture that needs to manage these patients? Local anesthesia? Hematoma block? Nothing (aka brutacaine)? What about ketamine, that seems popular these days. IV? IM? With or without atropine? So many decisions!Luckily you were surfing the internet one night a........ Read more »

How thinking for others can boost your creativity

by BPS Research Digest in BPS Research Digest

Distancing ourselves from a problem can help us reach the solution
The next time you're struggling to solve a creative problem, try solving it for someone else. According to Evan Polman and Kyle Emich, we're more capable of mental novelty when thinking on behalf of strangers than for ourselves. This is just the latest extension of research into construal level theory, an intriguing concept that suggests various aspects of psychological distance can affect our thinking style.

It's been shown, ........ Read more »

Moving through the matrix

by Becky in It Takes 30

Blood vessel formation is one of the wonderful adaptive processes in biology.  If a tissue is under-oxygenated, it sends out a cry for help and lo and behold, a new blood vessel forms.  This is great if the rescued tissue was under-oxygenated because it was cut off from its normal supply by a wound.  It’s [...]...

Cardiology: Jugular Venous Pressure (JVP)

by Science Exploiter in Science Exploits

If you ask anyone with a clinical background to explain bradycardia, you will get a very simple yet sufficient response: a heart rate below 60 beats per minute (bpm).  However, if you ask that same person to relate it to jugular venous pressure, more often than not you can expect to receive a blank stare.  Why?  Simple: very few actually understand venous pressure waves.  Jugular venous waveforms quantify the pressure within the venous system—which ultimately feeds into the........

When greenbelts fail

by Tim De Chant in Per Square Mile

Parks are often preservationists’ first line of defense against sprawl. To many, they’re a win-win arrangement—less rambling development and more open space. But the same qualities that make them attractive to planners—higher property values, more recreational opportunities, and pleasing aesthetics—also draws new residents, undermining their sprawl-fighting virtues. Greater London and the San Francisco Bay Area [...]... Read more »

Anti-carnivore alliances as community symbols

by DeLene Beeland in Wild Muse

When wolves and livestock, or pets, come into conflict with each other, people’s tolerance for wolves on the landscape tends to decrease. Part of the problem is the economic loss to the livestock producer, so some predator conservation organizations offer compensation payments for wolf-killed livestock as a tool to increase tolerance for wolves. Additional reasons [...]... Read more »

Farmer Joe Dictyostelium

by Moselio Schaechter in Small Things Considered

The practice of agriculture is not limited to humans: ants, termites, and snails all grow fungi, and who knows who else do something similar. But not many have claimed that such activities are to be found among simpler organisms. Now we have a report that slime molds have also gone down the road to agriculture. Dictyostelium discoideum, the best studied of the cellular slime molds, is a social amoeba that thrives by grazing on bacteria. Given ample bacterial food, these organisms grow as single ........
