Active shooter training increases comfort level of emergency responders

2014-07-10
(Press-News.org) (Boston) – Emergency Medical Service (EMS) responders felt better prepared to respond to an active shooter incident after receiving focused tactical training according to a new study in the journal Prehospital and Disaster Medicine. This is the first study to specifically examine the EMS provider comfort level with respect to entering a scene where a shooter has not yet been neutralized or working with law enforcement personnel during that response.

Incidents such as the Columbine High School shooting, the Virginia Tech campus shooting, the 2009 Fort Hood shooting, the movie theater shooting in Aurora, Colorado, and more recently, the Sandy Hook elementary school shooting remind us of the relative frequency of these events compared to most other mass casualty incidents for which EMS trains and prepares.

For this study, EMS providers responded to an anonymous survey both before and after a four-hour training session on joint EMS/police active shooter rescue team response. Survey questions focused on individual provider comfort level when responding to active shooter incidents compared to conventional HAZMAT incidents; comfort with providing medical care in an active shooter environment; perception of EMS provider role in an active shooter incident; and the appropriate timing of EMS response at the scene.

The survey results showed that more participants felt adequately trained to respond to an active shooter incident after focused training (87 percent) compared to before the training (36 percent) regardless of a providers prior tactical experience. Additionally, more EMS providers felt more comfortable working jointly on rescue operations with law enforcement personnel in response to an active shooter incident after training participation (93 percent) compared to before the training (61 percent).

According to the researchers, despite rapid deployment of law enforcement to neutralize an active shooter, it is not uncommon for a significant amount of time to pass before law enforcement has rendered the scene "safe." "Unfortunately this unintentionally prolongs the time before victims can receive life-saving care on the scene, as well as at a definitive care facility," explained lead author Jerrilyn Jones, MD, a clinical instructor of emergency medicine at Boston University School of Medicine and EMS Fellow at Boston EMS. "Our study showed that after receiving appropriate training, EMS providers felt better equipped to work on joint rescue operations even if an active shooter was still present," added Jones, who also is an emergency room physician at Boston Medical Center.

The researchers recommend further studies be undertaken to determine the significance of such training as well as the mortality impact on patient outcomes.

Scorpions are master architects, according to new research from Ben-Gurion University
2014-07-10
BEER-SHEVA, Israel – Ben-Gurion University of the Negev scientists have discovered that scorpions create a platform in their burrows where they warm up before the evening hunt. As ectothermic animals, scorpions rely on energy from the environment to regulate their internal temperature. The researchers believe that this platform provides a safe, warm spot for the scorpions to increase their body temperature before they leave their hiding places to forage at night. After trapping the wild large-clawed scorpions (Scorpio maurus palmatus) in Israel's Negev desert the ...

NASA-NOAA Suomi NPP satellite sees power within newborn Tropical Depression 09W

NASA-NOAA Suomi NPP satellite sees power within newborn Tropical Depression 09W
2014-07-10
As the Northwestern Pacific is bidding goodbye to Tropical Cyclone Neoguri, another tropical depression has formed. NASA-NOAA's Suomi NPP satellite passed over Tropical Depression 09W (TD09W) and captured infrared data on the storm indicating some powerful thunderstorms within. Because TD09W is close to land areas, watches are already in effect. On July 10, a tropical storm watch is in force for Guam, Rota, Tinian and Saipan. Tropical depression 09W was formerly known as low pressure System 92W. VIIRS instrument aboard NASA-NOAA's Suomi NPP satellite taken July 10 at ...

Scripps Florida scientists shed new light on nerve cell growth

Scripps Florida scientists shed new light on nerve cell growth
2014-07-10
JUPITER, FL, July 10, 2014 – Amidst the astounding complexity of the billions of nerve cells and trillions of synaptic connections in the brain, how do nerve cells decide how far to grow or how many connections to build? How do they coordinate these events within the developing brain? In a new study, scientists from the Florida campus of The Scripps Research Institute (TSRI) have shed new light on these complex processes, showing that a particular protein plays a far more sophisticated role in neuron development than previously thought. The study, published in the journal ...

On the link between periodontitis and atherosclerosis

2014-07-10
Chronic oral infection with the periodontal disease pathogen, Porphyromonas gingivalis, not only causes local inflammation of the gums leading to tooth loss but also is associated with an increased risk of atherosclerosis. A study published on July 10th in PLOS Pathogens now reveals how the pathogen evades the immune system to induce inflammation beyond the oral cavity. Like other gram-negative bacteria, P. gingivalis has an outer layer that consists of sugars and lipids. The mammalian immune system has evolved to recognize parts of this bacterial coating, which then ...

New research finds ocean's most abundant organisms have clear daily cycles

2014-07-10
Imagine the open ocean as a microbial megacity, teeming with life too small to be seen. In every drop of water, hundreds of types of bacteria can be found. Now scientists have discovered that communities of these ocean microbes have their own daily cycles—not unlike the residents of a bustling city who tend to wake up, commute, work, and eat at the same times. What's more, it's not all about the sun. Light-loving photoautotrophs—bacteria that need solar energy to help them photosynthesize food from inorganic substances—have been known to sun themselves on a regular schedule. ...

Window of opportunity against HIV comes from 'fitness bottleneck'

2014-07-10
New research on HIV transmission shows that viral fitness is an important basis of a "genetic bottleneck" imposed every time a new person is infected. The findings define a window of opportunity for drugs or vaccines to prevent or limit infection. HIV represents evolution on overdrive. Every infected individual contains a swarm of viruses that exhibit variability in their RNA sequence, and new mutations are constantly appearing. Yet nearly every time someone new is infected, this diverse population of viruses gets squeezed down to just one individual. The genetic bottleneck ...

Study points to potential new target for antibiotics against E. coli, other bugs

2014-07-10
COLUMBUS, Ohio – Scientists have identified a protein that is essential to the survival of E. coli bacteria, and consider the protein a potential new target for antibiotics. In the study, the researchers confirmed that this protein, called MurJ, flips a fatty molecule from one side of a bacterial cell membrane to the other. If that molecule isn't flipped, the cell cannot construct a critical layer that keeps pressurized contents of the cell contained. If those contents aren't contained, the cell bursts. E. coli is part of the gram-negative family of bacteria, characterized ...

Cultured CTCs reveal genetic profile, potential drug susceptibility of breast cancer cells

2014-07-10
Circulating tumor cells captured with a microchip-based device developed at the Massachusetts General Hospital (MGH) Center for Engineering in Medicine and the MGH Cancer Center can be cultured to establish cell lines for genetic analysis and drug testing. In the July 11 issue of Science, an MGH research team reports that the cultured cells accurately reflect a tumor's genetic mutation over time and changing susceptibility to therapeutic drugs. "We now can culture cells from the blood that represent those present in metastatic deposits, which allows testing for drug ...

Inherited 'memory' of environmental impact on health may be limited

2014-07-10
When a pregnant mother is undernourished, her child is at a greater than average risk of developing obesity and type 2 diabetes, in part due to so-called 'epigenetic' effects. A new study in mice demonstrates that this 'memory' of nutrition during pregnancy can be passed through sperm of male offspring to the next generation, increasing risk of disease for her grandchildren as well. In other words, to adapt an old maxim, 'you are what your grandmother ate'. The study also raises questions over how epigenetic effects are passed down from one generation to the next – and ...

Researchers harness a powerful new source of up-to-date information on economic activity

2014-07-10
ANN ARBOR--- Researchers at the University of Michigan, University of California Berkeley, and Arizona State University have developed a new data infrastructure for measuring economic activity. The infrastructure uses aggregated and de-identified data on transactions and account balances from Check, a mobile payments app, to produce accurate and comprehensive measures of consumers' spending and income on a daily basis. In a paper appearing in the July 11 issue of Science, economists Michael Gelman, Shachar Kariv, Matthew Shapiro, Dan Silverman, and Steven Tadelis ...
