Adolescent alcohol abuse disrupts transitions into early adulthood

Adolescent alcohol abuse disrupts transitions into early adulthood

Prior research has shown strong associations between adolescent alcohol abuse and adverse outcomes in early adulthood. A first-of-its-kind study of linkages between adolescent alcohol abuse and adverse adult outcomes has examined the influence of differences in familial background and shared genetics on this association; findings are consistent with a causal relationship between adolescent drinking and subsequent alcohol-related adult problems that cannot be fully explained by shared genetic and environmental liabilities. Results will be published in the August 2014 online-only issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View Continue reading

Anti-tank missile detector joins fight against malaria

Anti-tank missile detector joins fight against malaria

State-of-the-art military hardware could soon fight malaria, one of the most deadly diseases on the planet. Researchers at Monash University and the University of Melbourne have used an anti-tank Javelin missile detector, more commonly used in warfare to detect the enemy, in a new test to rapidly identify malaria parasites in blood. Scientists say the novel idea, published in the journal Analyst , could set a new gold standard for malaria testing Continue reading

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells Continue reading

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells. The nanoparticle is coated with a special protein, which looks for specific signals given off by tumours, and when it finds a tumour it begins to interact with the cancerous cells. Continue reading

3D printed anatomy to mark a new era for medical training

The creators of a unique kit containing anatomical body parts produced by 3D printing say it will revolutionize medical education and training, especially in countries where cadaver use is problematical. Continue reading

Smell and eye tests show potential to detect Alzheimer’s early

Smell and eye tests show potential to detect Alzheimer’s early

A decreased ability to identify odors might indicate the development of cognitive impairment and Alzheimer’s disease, while examinations of the eye could indicate the build-up of beta-amyloid, a protein associated with Alzheimer’s, in the brain, according to the results of four research trials reported today at the Alzheimer’s Association International Conference® 2014 (AAIC® 2014) in Copenhagen. In two of the studies, the decreased ability to identify odors was significantly associated with loss of brain cell function and progression to Alzheimer’s disease. In two other studies, the level of beta-amyloid detected in the eye (a) was significantly correlated with the burden of beta-amyloid in the brain and (b) allowed researchers to accurately identify the people with Alzheimer’s in the studies.

Neighborhoods with healthy food options less likely to have overweight kids

Neighborhoods with healthy food options less likely to have overweight kids

Children with a greater number of healthy food outlets near their homes had a reduced likelihood of being overweight or obese, finds an Australian study published in American Journal of Health Promotion . Children who had access to at least one healthy food outlet within 800 meters (about half a mile) of their home had a 38 percent decreased risk of being overweight or obese compared to those who did not Continue reading

Insulin pumps result in better blood sugar control than multiple daily injections in people with type 2 diabetes

Insulin pumps result in better blood sugar control than multiple daily injections in people with type 2 diabetes

Type 2 diabetes is usually controlled by diet and medication, but most people with advanced disease also end up needing insulin therapy to achieve control of their blood sugar. Continue reading

Noninvasive advanced image analysis could lead to better patient care

Noninvasive advanced image analysis could lead to better patient care

Lung cancer patients could receive more precise treatment, and their progress could be better tracked, using a new high-tech method of non-invasive medical imaging analysis, according to a study published by the journal PLOS ONE . Genetic changes increasingly are recognized as driving cancer development. But obtaining evidence of these changes usually requires a biopsy, which can be problematic for sensitive regions of the body such as the lungs. Continue reading
