Researchers highlight shoulder and elbow injury possibility in youth players
Speed, height, and pitching for multiple teams increases risk
2015-03-28
(Press-News.org) Las Vegas, NV - Pitching speed, player's height, and pitching for multiple teams may correlate with a history of shoulder and elbow injuries, according to new research released today at the American Orthopaedic Society for Sports Medicine's (AOSSM) Specialty Day.
"Our findings indicate that a 10 inch increase in height is associated with a 20% increase in likelihood of a history of injury, a 10 mile per hour increase in velocity is associated with a 12% increase likelihood of a history of injury, and playing for more than one team is associated with a 22% increase in the likelihood of a history of injury. Using these three factors alone allowed accurate prediction of 77% of injury histories," said lead author, Peter N. Chalmers, MD from Rush University Medical Center in Chicago, where the study took place.
Chalmers, and his co-authors Terrance Sgroi DPT, Andrew Riff MD, Matthew Lesniak DPT, Eli Sayegh BS, Nikhil Verma MD, Brian Cole MD MBA, and Anthony Romeo MD, evaluated 420 youth and adolescent pitchers in pre-season training using two-camera, high-definition, high-speed video analysis. The players' pitching and injury history were also collected. Thirty-one percent had a history of a previous injury and 30% had current pitching-related pain. Shoulder and elbow pain and injury are common in youth baseball players and significant research has been done to evaluate causes. This study is one of the few to evaluate breaking pitches as a risk factor for injury, although breaking pitchers did not correlate with injury history once the authors had accounted for pitch velocity.
"Pitch velocity was the single strongest correlate with a history of shoulder and elbow injury.," said Chalmers. "The current USA Baseball, Little League America, and Major League Baseball recommendations lead to youth and adolescent pitchers throwing a lower number of pitches at a high velocity, but this strategy may not decrease the "peak" stresses experienced by the elbow and thus may not decrease the risk of injury. Further study is needed."

A study published today in the journal Science found that government biofuel policies rely on reductions in food consumption to generate greenhouse gas savings.
Shrinking the amount of food that people and livestock eat decreases the amount of carbon dioxide that they breathe out or excrete as waste. The reduction in food available for consumption, rather than any inherent fuel efficiency, drives the decline in carbon dioxide emissions in government models, the researchers found.
"Without reduced food consumption, each of the models would estimate that biofuels generate ...

HOUSTON - (March 27, 2015) - Saudi Arabia's role in global energy markets is changing, according to a new paper from an energy expert at Rice University's Baker Institute for Public Policy. The researcher found that the kingdom is reshaping itself as a supplier of refined petroleum products while moving beyond its long-held role as a simple exporter of crude oil.
"A Refined Approach: Saudi Arabia Moves Beyond Crude" examines the growth of Saudi refining, the country's increased domestic demand for crude oil and the geopolitical effects of this development. The paper was ...

In the world of bird fashion, the guys seem to have all the fun: brighter feathers, sharper accessories, more pizzazz.
Researchers going back to Charles Darwin have focused on the contrast between the sexes, attributing the males' brighter colors to their need to attract mates.
A group of researchers at University of Wisconsin-Milwaukee took a different approach, testing a hypothesis that evolution has actually resulted in similarities among the sexes as much as differences.
Looking at nearly 1,000 species of birds, they found that while males often have brighter ...

TAMPA, Fla. - Moffitt Cancer Center researchers are using integrative approaches to study cancer by combining mathematical and computational modeling with experimental and clinical data. The use of integrative approaches enables scientists to study and model cancer progression in a manner that conventional experimental systems are unable to do.
Alexander Anderson, Ph.D., chair of the Department of Integrated Mathematical Oncology (IMO) and Mark Robertson-Tessi, an applied research scientist in IMO, recently published a commentary on an integrative approach used to study ...

The promising new material molybdenum disulfide (MoS2) has an inherent issue that's steeped in irony. The material's greatest asset--its monolayer thickness--is also its biggest challenge.
Monolayer MoS2's ultra-thin structure is strong, lightweight, and flexible, making it a good candidate for many applications, such as high-performance, flexible electronics. Such a thin semiconducting material, however, has very little interaction with light, limiting the material's use in light emitting and absorbing applications.
"The problem with these materials is that they are ...

Scientists working at the National Institute of Standards and Technology (NIST) and the National Institutes of Health (NIH) have devised and demonstrated a new, shape-shifting probe, about one-hundredth as wide as a human hair, which is capable of sensitive, high-resolution remote biological sensing that is not possible with current technology. If eventually put into widespread use, the design could have a major impact on research in medicine, chemistry, biology and engineering. Ultimately, it might be used in clinical diagnostics.
To date, most efforts to image highly ...

March 27, 2015 - For people with low vision who need bioptic telescopic glasses to drive, previous driving experience and the need for more training hours are the main factors affecting performance on driver's license road tests, according to a study in the April issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
After driving experience is taken into account, visual factors have no significant effect on road test scores in drivers using bioptic devices, report Bradley E. Dougherty, ...

Cold snaps like the ones that hit the eastern United States in the past winters are not a consequence of climate change. Scientists at ETH Zurich and the California Institute of Technology have shown that global warming actually tends to reduce temperature variability.
Repeated cold snaps led to temperatures far below freezing across the eastern United States in the past two winters. Parts of the Niagara Falls froze, and ice floes formed on Lake Michigan. Such low temperatures had become rare in recent years. Pictures of icy, snow-covered cities made their way around ...

University of Notre Dame applied mathematician Mark Alber and environmental biotechnologist Robert Nerenberg have developed a new computational model that effectively simulates the mechanical behavior of biofilms. Their model may lead to new strategies for studying a range of issues from blood clots to waste treatment systems.
"Blood clotting is a leading cause of death in the United States at this point," said Alber, who is The Vincent J. Duncan Family Professor of Applied Mathematics in the College of Science and an adjunct professor of medicine at the Indiana University ...

TEMPE, Ariz. (March 27, 2015) - As more people move to different regions of the country it will require planners to use as many tools as they can to develop urban areas that satisfy population demands and not over burden the environment.
A new study from Arizona State University (ASU) details some of the dynamics at play as one region of the country, the Central Valley of California, braces for substantial population growth and all it entails. The study, based on computer simulations using the ASU Advanced Computing Center, of rural to urban land conversion shows that ...
