Although adolescent sports-related deaths are rare, they are commonly caused by cardiovascular problems, such as commotio cardis--cardiac arrest caused by being hit in the chest with an object, such as a baseball or softball, usually traveling 30 to 50 miles per hour. The frequency of this problem is not known, but the survival rate is low among reported cases. However, the survival rate may be increased when cardiopulmonary resuscitation (CPR) is performed and an automated external defibrillator (AED) is used within three minutes of impact. An article in the December issue of The Journal of Pediatrics examines one report of how CPR training and the use of an AED can increase the survival rate for adolescents experiencing commotio cardis on the playing field.
Dr. Neal Thomas and colleagues from Penn State Childrens Hospital, Penn State College of Medicine, Penn State Milton S. Hershey Medical Center, and Minneapolis Heart Institute Foundation reported a healthy 13-year-old boy who suffered cardiac arrest after being hit in the chest by a pitch while at bat in a baseball game. The coaching staff immediately began administering CPR, and 6-8 minutes later the paramedics arrived and used an AED. The boy was taken to the emergency room and was awake, talking, and following commands within one hour of his arrival; he was discharged from the hospital after three days.
Since 62% of cases of commotio cardis have been reported to occur during competitive sporting events, Dr. Thomas points out that "more effective first-responder therapy is needed." Timeliness, training, and equipment are all important aspects of delivering effective treatment. Although the average cost of an AED is $2,500, survival rates for commotio cardis may increase to 25% if resuscitative measures are taken within three minutes of impact; delayed efforts or CPR-only can reduce the survival rate to 3%. Chest protector equipment can reduce the risk of commotio cardis, but 28% of cases of commotio cardis occurred in spite of this protection. Dr. Thomas suggests that "communities and school districts reexamine the need for accessible AEDs and CPR-trained coaches at organized sporting events for children."

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
