A Henry Ford Hospital study found that simulation training improved the critical decision-making skills of medical residents performing actual resuscitations in the Emergency Department.
Researchers say the residents performed better in four key skill areas after receiving the simulation training: leadership, problem solving, situational awareness and communication. Their overall performance also sharpened.
While many studies have shown the benefits of simulation training for honing the skill level of medical professionals, Henry Ford

Respiratory movement during radiotherapy makes it difficult to hit the right treatment target and this in turn can lead to an under-dose of radiation to the tumour, or a potentially toxic over-dose to the surrounding healthy tissue. Getting this right is a real challenge for the radiotherapist, but new techniques are helping to deliver the correct dose to the right place.

A new electronic medical record tool that tallies patients’ previous radiation exposure from CT scans helps reduce potentially unnecessary use of the tests among emergency room patients with abdominal pain, according to a study from researchers at the Perelman School of Medicine at the University of Pennsylvania. The new study shows that when the tool is in use, patients are 10 percent less likely to undergo a CT scan, without increasing the number of patients who are admitted to the hospital.
Abdominal pain is the most common reason why people seek care in emergency rooms in the United States, accounting for 10 million visits each year. But the symptoms may be caused by myriad problems, from those that can be fixed with a single dose of an over-the-counter drug to those that could prove life-threatening within hours: from a bout of GI distress to an ectopic pregnancy; from constipation to an appendix about to burst; from a hernia to signs of a chronic condition like Crohn’s disease.
This complex diagnostic face-off plays a huge role in why emergency physicians tend to lean heavily on tests like CT scans, even though they expose patients to radiation and there are few clear guidelines on which patients should get them. Since the mid-1990s, the use of CT scans to diagnose ER patients has surged, increasing ten-fold. Today, 14 percent of all emergency room patients get scanned

A team from the Institute of Photonic Sciences (ICFO) has developed a technique to measure internal cell temperatures without altering their metabolism. This finding could be useful when distinguishing healthy cells from cancerous ones, as well as learning more about cellular processes.
Temperature controls many of the cell’s life processes, such as splitting and metabolism. A European research team led by the Institute of Photonic Sciences (ICFO), which has the Severo Ochoa mark of excellence, has published a non-invasive method that offers quicker, more precise data from measuring intracellular heat from green fluorescent proteins (GFP).
‘A unique characteristic of our method is that it does not alter any cellular process’ Romain Quidant, ICFO researcher and study co-ordinator, explains to SINC. Unlike other techniques, this method does not stress or alter the behaviour of the cell as it does not need to be inserted into any molecules or any other synthetic nano-object that is sensitive to the internal temperature.
One of the most promising outcomes is a better understanding of cellular processes, such as those involved in metastasis. Furthermore, the possibility of obtaining information about intracellular temperature could be used to ‘differentiate normal cells from cancerous ones in a quick, non-invasive manner’ Sebastian Thompson Parga, ICFO researcher and co-author of the project.
From intracellular temperature, we can deduce how the energy used by the body in the uncontrolled spreading of cancer cells flows.
In this interdisciplinary study, biology uses physical measurements of energy transmission to study processes such as gene expression, metabolism and cell splitting.
The technique used is known by the name of ‘fluorescence polarisation anisotropy’ (FPA) as it allows the difference in polarisation between light that fluorescent molecules receive, and that which they emit later, to be measured. In the words of Quidant, ‘this difference in polarisation (anisotropy) is directly connected to the rotating of the GFP molecules and therefore with temperature’.
The authors of the study ensure that biologists will be able to implement this technique in experimental set-ups and obtain the cell temperature as another observable detail. In 2008, when Osamu Shimomura, Martin Chalfie and Roger Y. Tsien won the Nobel Chemistry Prize for discovering and developing GFP, they resolved many complications in biomedical research.
