Bringing medical testing to remote locales - American Chemical Society podcast
Date: Jan-30-2014The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series features a small, paper-based device that can monitor or detect disease with no electricity or expensive lab analyses required.Based on a report by Scott T. Phillips, Ph.D., in the ACS journal Analytical Chemistry, the new podcast is available without charge at iTunes and from here.Phillips explains that people living in places with limited resources often don't have the means to purchase and operate conventional medical tests.
The importance of parenting as African American boys transition from preschool to kindergarten
Date: Jan-30-2014A new study from UNC's Frank Porter Graham Child Development Institute (FPG) has found that parenting affects the academic and social performance of African American boys as they move from preschool to kindergarten."The transition to kindergarten can be challenging for many children due to new expectations, social interactions, and physiological changes," said Iheoma Iruka, FPG's associate director of research and the study's lead author. "Transitions may be even more arduous for African American boys, given the many challenges they are likely to face compared to their peers.
Aspirin still overprescribed for stroke prevention in atrial fibrillation despite potential for dangerous side effects
Date: Jan-30-2014Aspirin is still overprescribed for stroke prevention in atrial fibrillation (AF) despite the potential for dangerous side effects, according to research just published.Professor Gregory Y.H. Lip, lead author of the European Society of Cardiology (ESC) study, said: "The perception that aspirin is a safe and effective drug for preventing strokes in AF needs to be dispelled.
Limited success for malaria screening in schools
Date: Jan-30-2014School-based intermittent screening and treatment programs for malaria may be unsuccessful in low to moderate transmission areasA school-based intermittent screening and treatment program for malaria in rural coastal Kenya had no benefits on the health and education of school children, according to a study by international researchers published in this week's PLOS Medicine.The study, led by Katherine Halliday and Simon Brooker from the London School of Hygiene & Tropical Medicine, included over 5000 children from 101 government schools.
Premature birth is associated with increased risk of asthma and wheezing disorders
Date: Jan-30-2014Children who are born preterm have an increased risk developing asthma and wheezing disorders during childhood according to new research published in PLOS Medicine.The research by Jasper Been, from the Maastricht University Medical Centre (Netherlands) and The University of Edinburgh (UK), and colleagues at Harvard Medical School (US) is a systematic review and meta-analysis of 30 unique studies that collectively involved approximately 1.5 million children.
First ever genome-wide association study of combined phenotype may allow for improved identification of variants associated with asthma-with-hay fever
Date: Jan-30-201423andMe, the leading personal genetics company, has participated in the first ever genome-wide association study of the combined asthma-with-hay fever phenotype. Led by researchers at the QIMR Berghofer Medical Research Institute, the study identified 11 independent genetic markers associated with the development of asthma-with-hay fever, including two associations reaching a level of significance with allergic disease for the first time. Through these findings, 23andMe aims to substantially improve the ability to detect genetic risk factors shared between both diseases.
A silk coat for diamonds makes sleek new imaging and drug delivery tool
Date: Jan-30-2014Silk and diamonds aren't just for ties and jewelry anymore. They're ingredients for a new kind of tiny glowing particle that could provide doctors and researchers with a novel technique for biological imaging and drug delivery.The new particles, just tens of nanometers across, are made of diamond and covered in silk. They can be injected into living cells, and because they glow when illuminated with certain kinds of light, biologists can use them to peer inside cells and untangle the molecular circuitry that governs cellular behavior, or to study how cells react to a new drug.
Gossip and ostracism may have hidden group benefits
Date: Jan-30-2014Conventional wisdom holds that gossip and social exclusion are always malicious, undermining trust and morale in groups. But sharing this kind of "reputational information" could have benefits for society, according to a new study published in Psychological Science, a journal of the Association for Psychological Science.Robb Willer, an associate professor of sociology at Stanford University, explored the nature of gossip and ostracism in collaboration with co-authors Matthew Feinberg, a postdoctoral researcher at Stanford, and Michael Schultz from the University of California-Berkeley.
Inflammatory marker TSPO could form the basis of the first noninvasive test for heart inflammation
Date: Jan-30-2014A biomarker widely used to diagnose brain injury has shown early promise for assessing the severity of heart inflammation, or myocarditis, find researchers at Columbia University's Mailman School of Public Health, Johns Hopkins, and the Mayo Clinic.The study is published online in the January issue of the Journal of Cardiovascular Translational Research.At present, there is no noninvasive method to confirm diagnosis of myocarditis, which can progress to heart failure and death. The current standard of biopsy is risky and often misses the disease.
