Heading a soccer ball may affect cognitive performance

In tablet-based experiment, subconcussive head impacts in soccer affect players' performance of certain tasks

2013-02-28

(Press-News.org) Sports-related head injuries are a growing concern, and new research suggests that even less forceful actions like 'heading' a soccer ball may cause changes in performance on certain cognitive tasks, according to a paper published February 27 in the open access journal PLOS ONE by Anne Sereno and colleagues from the University of Texas Health Science Center at Houston.

The researchers tested the effects of non-injurious head-to-ball impacts on cognitive function using a tablet-based app. They found that high school female soccer players were significantly slower than non-players on a task that required pointing away from a target on the screen, but showed no difference in performance when pointing to the on-screen visual target.

According to the study, tasks that involve pointing away from a target require specific voluntary responses, whereas moving toward a target is a more reflexive response. Based on their observations, the authors conclude that sub-concussive blows to the head may cause changes specifically linked to certain cognitive functions. The authors say that the app used in their research may be a quick and effective way to screen for and track cognitive changes in athletes. They add that a tablet-based application for such quick screens may also have broader applications in the clinic or the field.

Wii-playing surgeons may improve performance on laparoscopic procedures

2013-02-28

Laparoscopic surgeons may improve certain aspects of surgical performance by regularly playing on a Nintendo® Wii, according to research published February 27 in the open access journal PLOS ONE by Gregorio Patrizi and colleagues from the University of Rome, Italy. Considering the technical skills required to perform laparascopic procedures, several studies aim to evaluate and improve training for surgeons outside the operating room. Previous studies have assessed the effect of playing video games on hand-eye coordination and spatial attention. In the current research, ...

Children with autism show increased positive social behaviors when animals are present

2013-02-28

The presence of an animal can significantly increase positive social behaviors in children with autism spectrum disorders (ASD), according to research published February 20 in the open access journal PLOS ONE by Marguerite E O'Haire and colleagues from the University of Queensland, Australia. The authors compared how 5-13 year old children with ASD interacted with adults and typically-developing peers in the presence of two guinea pigs compared to toys. They found that in the presence of animals, children with ASD demonstrated more social behaviors like talking, looking ...

Nut-cracking monkeys use shapes to strategize their use of tools

VIDEO: This video shows two episodes in which a bearded capuchin monkey places and strikes a nut with the Stop meridian marked with a black line or a black-hatched line, and... Click here for more information. Bearded capuchin monkeys deliberately place palm nuts in a stable position on a surface before trying to crack them open, revealing their capacity to use tactile information to improve tool use. The results are published February 27 in the open access journal PLOS ...

Ectopic eyes function without connection to brain

2013-02-28

MEDFORD/SOMERVILLE, Mass. (February 27, 2013) – For the first time, scientists have shown that transplanted eyes located far outside the head in a vertebrate animal model can confer vision without a direct neural connection to the brain. Biologists at Tufts University School of Arts and Sciences used a frog model to shed new light – literally – on one of the major questions in regenerative medicine, bioengineering, and sensory augmentation research. "One of the big challenges is to understand how the brain and body adapt to large changes in organization," says Douglas ...

Infusion of stem cells and specially generated T-cells from same donor improves leukemia survival

2013-02-28

SEATTLE – In a significant advance for harnessing the immune system to treat leukemias, researchers at Fred Hutchinson Cancer Research Center for the first time have successfully infused large numbers of donor T-cells specific for a key anti-leukemic antigen to prolong survival in high-risk and relapsed leukemia patients after stem cell transplantation. Both the stem cells for transplant and the T-cells came from the same matched donors. Reporting results of a pilot clinical trial in the Feb. 27 issue of the journal Science Translational Medicine, researchers describe ...

Risk of heart attack death may increase after adult sibling's death

2013-02-28

Your risk of dying from a heart attack may increase after your adult sibling dies, according to new research in the Journal of the American Heart Association. "Death of a family member is so stressful that the resulting coping responses could lead to a heart attack," said Mikael Rostila, Ph.D., lead author of the study and associate professor at Stockholm University/Karolinska Institutet in Stockholm, Sweden. "But our results suggest that this association between the loss of a sibling and having a heart attack is more likely to occur some years after bereavement." The ...

Researchers look to breath to identify stress

2013-02-28

The perennial stress-buster – a deep breath – could become stress-detector, claims a team of researchers from the UK. According to a new pilot study, published today, 28 February, in IOP Publishing's Journal of Breath Research, there are six markers in the breath that could be candidates for use as indicators of stress. The researchers hope that findings such as these could lead to a quick, simple and non-invasive test for measuring stress; however, the study, which involved just 22 subjects, would need to be scaled-up to include more people, over a wider range of ...

Modified protein could become first effective treatment for vitiligo

2013-02-28

MAYWOOD, Il. – Loyola University Chicago Stritch School of Medicine researchers have developed a genetically modified protein that dramatically reverses the skin disorder vitiligo in mice, and has similar effects on immune responses in human skin tissue samples. The modified protein is potentially the first effective treatment for vitiligo, which causes unsightly white patches on the face, hands and other parts of the body. Loyola University Chicago has submitted a patent application for the protein, and researchers are seeking regulatory approval and funding for a ...

Spinal cancer: Guidelines for diagnosis unsupported in patients with lower back pain

2013-02-28

A new systematic review published in The Cochrane Library has raised doubts as to the effectiveness of "red flag" indicators at both identifying and excluding cancer in patients with lower back pain. The authors of the review concluded that most individual red flags were poor at diagnosing spinal malignancies and call for further studies focused on combinations of red flags. Lower back pain is a common complaint, often with no obvious cause. In around 1-5% of patients with lower back pain, the condition results from a more serious underlying problem, such as a tumour. ...

Screening decisions are better informed when risk information is personalized

2013-02-28

Patients' ability to make genuinely informed choices about undergoing disease screening increases when the risk information that they receive is related to their own personal risk, rather than average risks, according to the results of a Cochrane systematic review. The authors reviewed data from studies, largely on cancer screens, in which patients were provided with personalised risk estimates. The benefits of screening are not clear-cut. For example, screening can help detect cancer early, leading to successful treatment, but it can also lead to unnecessary treatment ...
