(Press-News.org) INDIANAPOLIS -- Millions of children worldwide live on the streets. A review and analysis of 50 studies on substance abuse by street children in 22 resource-constrained countries has found lifetime substance use to be both common and high, posing serious threats to their health as well as for their chances for reintegration into society.
"The most important conclusion to draw from this large number of studies is not only is substance abuse by street children highly prevalent in low-income countries; it is largely ignored," said Paula Braitstein, Ph.D., associate research professor of medicine at Indiana University School of Medicine and a Regenstrief Institute affiliated scientist. "These children are often malnourished, have significant health problems and lack education. This poses a massive public health problem, in terms of their future need for health care as well as potential for future productivity and/or re-integration back into society for countries with limited resources."
In the review, published online on July 12 by the journal Addiction, investigators led by Dr. Braitstein highlight the magnitude of the problem in resource-constrained countries, the causes and health consequences of drug use among street children, and areas where new research is needed. The work was supported in part by the Eunice Kennedy Shriver National Institute of Child Health and Human Development [R01HD060478].
The authors found that the most commonly used drugs among street children in low-income countries, as in middle-income countries, are inhalants such as glue, acetone, gasoline and paint thinner, followed by tobacco, alcohol and marijuana. Street children likely gravitate toward inhalants because they're cheap and legal, and therefore easy to get, according to Dr. Braitstein, who also holds appointments at Moi University and the University of Toronto.
Inhalants have been linked to cognitive and neurological impairment and psychological and physical dependence, developments that may make it harder for street children to reintegrate into society. Inhalants are also linked to sudden death from cardiac arrhythmia and other causes.
The prevalence of drug use among the millions of street children varies widely among countries, from 14 percent in Nigeria to 81 percent in India to an astronomical 92 percent in Honduras and Brazil. The most common reasons street children give for using drugs are peer pressure, escapism, pleasure, curiosity, and increasing courage and strength for life on the streets.
"As a result of this review, we learned that we don't really know enough about what causes street children to start and stop using drugs. We also found that many studies of street children focus on boys, so we have even less information about girls' drug use," Dr. Braitstein said. "Although we know that some street children exchange sex for drugs or have sex while under the influence of drugs, little else is known about the link between drug use and risky sex behavior. There are several critical gaps in our knowledge that we need to fill."

Health-care system factors may have less influence on kidney-related racial disparities
2013-07-12
Among kidney disease patients receiving pre-dialysis care in a universal healthcare system, black patients experienced a faster progression to kidney failure than whites.
The faster decline in kidney function among black compared with white patients was predominantly present in patients with diabetes and in patients with more advanced kidney dysfunction.
Findings may help explain why blacks are more prone to develop kidney failure than whites.

Novel drug acts in unique way to protect against kidney injury
2013-07-12
A novel drug called Bendavia can help prevent acute kidney injury in animal models and is currently being studied in clinical trials for kidney disease.
Bendavia acts by protecting a unique compound called cardiolipin, which is only found in mitochondria and is essential for keeping cells alive and functioning.
Acute kidney injury has more than doubled since 2000, causing nearly 39,000 deaths in 2009.
Washington, DC (July 11, 2013) — New research reveals the mechanism by which an experimental drug can protect the kidneys from sudden damage, called acute kidney injury ...
The brain processes complex stimuli more cumulatively than we thought
2013-07-12
A new study reveals that the representation of complex features in the brain may begin earlier—and play out in a more cumulative manner—than previously thought.
The finding represents a new view of how the brain creates internal representations of the visual world. "We are excited to see if this novel view will dominate the wider consensus" said senior author Dr. Miyashita, who is also Professor of Physiology at the University of Tokyo's School of Medicine, "and also about the potential impact of our new computational principle on a wide range of views on human cognitive ...
Geothermal power facility induces earthquakes, study finds
2013-07-12
An analysis of earthquakes in the area around the Salton Sea Geothermal Field in southern California has found a strong correlation between seismic activity and operations for production of geothermal power, which involve pumping water into and out of an underground reservoir.
"We show that the earthquake rate in the Salton Sea tracks a combination of the volume of fluid removed from the ground for power generation and the volume of wastewater injected," said Emily Brodsky, a geophysicist at the University of California, Santa Cruz, and lead author of the study, published ...

HIV used to cure 2 genetic diseases: The idea of an Italian scientist proves successful
2013-07-12
The AIDS virus can be used to treat two severe hereditary diseases. After an Italian scientist's "stroke of genius" in 1996, and after years of promising results in the laboratory, double official recognition by one of the most important international scientific journals has now arrived. And six children from all over the world, after three years of treatment, are well and show significant benefits. The announcement was made in two studies published today in Science* by researchers at the San Raffaele Telethon Institute for Gene Therapy (TIGET) in Milan, led by Luigi Naldini, ...
'Taste sensor' genes in female butterflies vital to species' survival, UCI study finds
2013-07-12
Irvine, Calif. — Giving the phrase "Mother knows best" a whole new meaning, UC Irvine researchers have identified unique genes in female butterflies that enable them to select the best host plant for their larvae – and avoid deadly ones.
Biologist Adriana Briscoe and colleagues found that females of the Heliconius species express gustatory, or taste, receptor genes when choosing a host on which to lay their eggs. Many plants defend themselves by producing toxic chemicals, so it's vital to their larvae's survival that the butterflies pick the right kind. Heliconius females ...
Distant quakes trigger tremors at US waste-injection sites, says study
2013-07-12
Large earthquakes from distant parts of the globe are setting off tremors around waste-fluid injection wells in the central United States, says a new study. Furthermore, such triggering of minor quakes by distant events could be precursors to larger events at sites where pressure from waste injection has pushed faults close to failure, say researchers.
Among the sites covered: a set of injection wells near Prague, Okla., where the study says a huge earthquake in Chile on Feb. 27, 2010 triggered a mid-size quake less than a day later, followed by months of smaller tremors. ...
Researchers estimate over 2 million deaths annually from air pollution
2013-07-12
Over two million deaths occur each year as a direct result of human-caused outdoor air pollution, a new study has found.
In addition, while it has been suggested that a changing climate can exacerbate the effects of air pollution and increase death rates, the study shows that this has a minimal effect and only accounts for a small proportion of current deaths related to air pollution.
The study, which has been published today, 12 July, in IOP Publishing's journal Environmental Research Letters, estimates that around 470,000 people die each year because of human-caused ...
Grazing slugs hinder grassland restoration
2013-07-12
Selective grazing by slugs may prevent key grassland species from taking hold and hampers efforts to restore our hay meadows, new research has shown.
Work by scientists at Newcastle University, UK, has looked at the impact slugs have on grassland biodiversity and how this might inform future restoration work.
Although renowned for their ability to chew through a gardener's prize petunias or strawberry patch, still relatively little is known about the effect these munching molluscs have on large scale grassland conservation projects.
But for the first time this latest ...
