Violent video games associated with increased aggression in children

2014-03-25
(Press-News.org) Bottom Line: Habitually playing violent video games appears to increase aggression in children, regardless of parental involvement and other factors.

Author: Douglas A. Gentile, Ph.D., of Iowa State University, Ames, and colleagues.

Background: More than 90 percent of American youths play video games, and many of these games depict violence, which is often portrayed as fun, justified and without negative consequences.

How the Study Was Conducted: The authors tracked children and adolescents in Singapore over three years on self-reported measures of gaming habits, aggressive behavior, aggressive cognition (AC, such as aggressive fantasies, beliefs about aggression, and attaching motives of hostility to ambiguous provocations) and empathy. The researchers also examined the effects of age, sex, parental monitoring and other traits.

Results: Among 3,034 children, a habit of playing violent video games was associated with long-term, self-reported aggressive behavior through increases in AC, regardless of parental involvement, age, sex and initial aggressiveness. Empathy did not appear to mediate the effects of playing violent video games on aggression. However, the authors suggest more investigation is needed before concluding the effects are entirely the result of changes in AC.

Discussion: "Because of the large number of youths and adults who play violent video games, improving our understanding of the effects is a significant research goal that has important implications for theory, public health and intervention strategies designed to reduce negative effects or to enhance potential positive effects." INFORMATION: Editor's Note: This work was supported by grants from the Ministry of Education and the Media Development Authority of Singapore.

E-cigarettes not associated with more smokers quitting, reduced consumption

2014-03-25
Bottom Line: The use of electronic cigarettes (e-cigarettes) by smokers is not associated with greater rates of quitting cigarettes or reduced cigarette consumption after one year. Author: Rachel A. Grana, Ph.D., M.P.H., and colleagues from the University California, San Francisco. Background: E-cigarettes are promoted as smoking cessation tools, but studies of their effectiveness have been unconvincing. How the Study Was Conducted: The authors analyzed self-reported data from 949 smokers (88 of the smokers used e-cigarettes at baseline) to determine if e-cigarettes ...

Natalizumab treatment in patients with MS associated with JC virus infection

2014-03-25
Treatment with natalizumab in patients with multiple sclerosis (MS) appears linked with JC virus (JCV) infection, which can lead to a rare and often fatal demyelinating disease of the central nervous system called progressive multifocal leukoencephalopathy (PML) that destroys the myelin that protects nerve cells. The movement of cells with JC virus into the blood stream may provide researchers with a possible reason why patients with MS develop PML Since natalizumab was reintroduced as a biologic therapy for MS in 2006, more than 440 cases of PML have been reported. ...

Researchers issue state-of-the-state on genetic-based testing and treatment for breast cancer

2014-03-25
(Lebanon, NH, 03/24/2014)- Dartmouth researchers at its Norris Cotton Cancer Center have compiled a review of the role that information gathered through genetic testing plays in the diagnosis and treatment of breast cancer. The paper entitled "Personalized Therapy for Breast Cancer" was accepted on March 17, 2014, for publication in Clinical Genetics. The paper discusses targeted therapies, new biomarkers, and the quality of commercially available testing methods. Genomic testing is changing the way breast cancer is diagnosed and treated. By examining a woman's genes ...

Excess weight at 1 year postpartum increases moms' risk for diabetes, heart problems

2014-03-25
TORONTO – 'Watch out for weight gain within a year of giving birth to prevent new risk of diabetes and cardiovascular disease.' That advice for women comes from a study published today in the journal Diabetes Care. While it has long been believed that not losing 'baby weight' for several years after pregnancy carries long-term risks of diabetes and heart disease the research team at Mount Sinai Hospital, Toronto, aimed to test this theory by tracking risk factors and weight in the first 12 months after giving birth. The team led by clinician-researcher Dr. Ravi ...

New drug raises potential for cancer treatment revolution

New drug raises potential for cancer treatment revolution
2014-03-25
A revolution in cancer treatment could soon be underway following a breakthrough that may lead to a dramatic improvement in cancer survival rates. A new study at the University of Warwick, published today in the journal Angewandte Chemie International Edition, has developed a new drug that can manipulate the body's natural signalling and energy systems, allowing the body to attack and shut down cancerous cells. Called ZL105, the drug is a compound based on the precious metal iridium. The study has found ZL105 could potentially replace currently used anticancer drugs, ...

Can virtual reality-based therapy help veterans overcome posttraumatic stress disorder?

Can virtual reality-based therapy help veterans overcome posttraumatic stress disorder?
2014-03-25
New Rochelle, NY, March 25, 2014—Posttraumatic stress disorder (PTSD) is common among military veterans and together with the often-related anxiety, depression, and psychological and emotional impairment can dramatically affect quality of life. A type of virtual reality (VR) treatment called Graded Exposure Therapy (GET) can improve PTSD symptoms and may also have a positive impact on these associated disorders, as described in an article in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is ...

Electronic medication alerts designed with provider in mind reduce prescribing errors

Electronic medication alerts designed with provider in mind reduce prescribing errors
2014-03-25
INDIANAPOLIS -- Changing how medication alerts are presented in electronic medical records resulted in safer prescribing, increased efficiency and reduced workload for health care providers who placed drug orders in a study published online in the Journal of the American Medical Informatics Association. "The VA electronic medical record system is one of the most widely used and respected EMR systems in the country," said Alissa L. Russ, Ph.D., a human factors engineer who led the study. "This EMR is used by providers at over 150 VA hospitals. We are looking at ways to ...

Pesticides make the life of earthworms miserable

Pesticides make the life of earthworms miserable
2014-03-25
Pesticides have a direct impact on the physiology and behaviour of earthworms, a Danish/French research team reports after having studied earthworms that were exposed to pesticides over generations. "We see that the worms have developed methods to detoxify themselves, so that they can live in soil sprayed with fungicide. They spend a lot of energy on detoxifying, and that comes with a cost: The worms do not reach the same size as other worms, and we see that there are fewer of them in sprayed soil. An explanation could be that they are less successful at reproducing, ...

RI Hospital: Number of patients admitted with antibiotic-resistant infections is rising

2014-03-25
PROVIDENCE, R.I. – The emergence of community-acquired infections, such as urinary tract infections (UTI), due to strains resistant to common antibiotics are on the rise, according to Rhode Island Hospital researchers. The study is published online in the journal Antimicrobial Resistance and Infection Control. "Over the last several years, we've seen an increase in the number of bacteria -- many of which are forms of E. coli -- that are resistant to commonly administered antibiotics," said Leonard Mermel, D.O., medical director of the department of epidemiology and infection ...

Twenty-five percent of breast cancer survivors report financial decline due to treatment

Twenty-five percent of breast cancer survivors report financial decline due to treatment
2014-03-25
ANN ARBOR, Mich. — Four years after being treated for breast cancer, a quarter of survivors say they are worse off financially, at least partly because of their treatment, according to a new study led by University of Michigan Comprehensive Cancer Center researchers. In addition, 12 percent reported that they still have medical debt from their treatment. Financial decline varied significantly by race, with Spanish-speaking Latinas most likely to be impacted. Debt was reported more frequently in English-speaking Latinas and Blacks, the study found. Results appear in ...
