New study charts the fate of chemicals affecting health, environment

New study charts the fate of chemicals affecting health, environment

Looking forward in science often requires looking back, evaluating trends to extrapolate future outcomes. A classic case is Moore’s Law, which predicts that the density of components on an integrated circuit will double every 24 months. Continue reading

New mechanism that can lead to blindness discovered

New mechanism that can lead to blindness discovered

An important scientific breakthrough by a team of IRCM researchers led by Michel Cayouette, PhD, is being published by The Journal of Neuroscience . The Montréal scientists discovered that a protein found in the retina plays an essential role in the function and survival of light-sensing cells that are required for vision. These findings could have a significant impact on our understanding of retinal degenerative diseases that cause blindness Continue reading

Tumor registry data find acadiana colon cancer rates among America’s highest

Tumor registry data find acadiana colon cancer rates among America’s highest

A special study using data from LSU Health New Orleans School of Public Health’s Louisiana Tumor Registry has found that colorectal cancer incidence rates in the Louisiana Acadian parishes are among the highest in the United States. This study appears to be the first to identify a high rate of cancer in a large, regional, US founder population, raising the possibility of a genetic predisposition. Continue reading

A special study using data from LSU Health New Orleans School of Public Health’s Louisiana Tumor Registry has found that colorectal cancer incidence rates in the Louisiana Acadian parishes are among the highest in the United States. This study appears to be the first to identify a high rate of cancer in a large, regional, US founder population, raising the possibility of a genetic predisposition. Alternatively, an unidentified, robust environmental risk factor may be present. Continue reading

French studies measure benefits of  colorectal cancer screening

French studies measure benefits of colorectal cancer screening

The introduction of biennial colorectal cancer screening in a region of France increased the rate of diagnosis of high risk pre-cancerous adenomas (sometimes called polyps) by 89%, researchers have reported at the ESMO 2014 Congress in Madrid. Dr Vanessa Cottet from INSERM Unité 866 in Dijon, France, and colleagues studied the region of Côte-d’Or, where a registry has been collecting data on adenomas since 1976. Continue reading

Realizing the promise of education: An effective early intervention program for substance exposed babies and toddlers

Realizing the promise of education: An effective early intervention program for substance exposed babies and toddlers

Two decades after its initiation, the University of Miami (UM) Linda Ray Intervention Program for substance-exposed babies and toddlers demonstrates long-term success. The program is designed to help children from birth to three years of age who are developmentally delayed, prenatally exposed to drugs and often with the additional risk of maltreatment, ultimately achieve their developmental milestones and be ready to enter kindergarten ready to learn. The program started in 1993 as an innovative partnership between the UM Linda Ray Intervention Center (LRIC), Miami-Dade Public Schools, Early Steps, Children’s Medical Services, and the Florida Diagnostic and Learning Resources System (FDLRS) and has since expanded to partner with the Juvenile Court in Miami.

Slight alterations in microRNA sequences hold more information than previously thought

Slight alterations in microRNA sequences hold more information than previously thought

Researchers have encountered variants or isoforms in microRNAs (miRNAs) before, but assumed that these variants were accidental byproducts. A recent study, published in the journal Oncotarget this month, shows that certain so called isomiRs have abundances that depend on geographic subpopulations and gender and that the most prevalent variant of a given miRNA may not be the one typically listed in the public databases Continue reading

Study warns swift action needed to curb exponential climb in Ebola outbreak

Study warns swift action needed to curb exponential climb in Ebola outbreak

Unless Ebola control measures in west Africa are enhanced quickly, experts from the WHO and Imperial College, London, predict numbers will continue to climb exponentially, and more than 20,000 people will have been infected by early November, according to a new article in the New England Journal of Medicine released 6 months after WHO was first notified of the outbreak in west Africa. In the article, public health epidemiologists and statisticians reviewed data since the beginning of the outbreak in December 2013 to determine the scale of the epidemic, better understand the spread of the disease, and what it will take to reverse the trend of infections Continue reading
