Home- versus mobile clinic-based HIV testing and counseling in rural Africa

2014-12-16
(Press-News.org) Home- and community-based HIV testing and counselling services can achieve high participation uptake in rural Africa but reach different populations within a community and should be provided depending on the groups that are being targeted, according to new research published in this week's PLOS Medicine by Niklaus Labhardt from the Swiss Tropical and Public Health Institute, and colleagues from SolidarMed, a Swiss non-governmental Organization for Health in Africa.

Annually, about 2.3 million people become newly infected with HIV, the virus that causes AIDS. A key step in receiving treatment for HIV and reducing further transmission of the virus is receiving HIV testing and counselling, but in countries where HIV is prevalent, such as many parts of rural Africa, access to these services can be limited by resources or because people fear stigmatization and discrimination. One option to improve HIV testing and counselling coverage is to provide this service to individuals in a community setting as part of a campaign that provides multiple health services (for example, family planning, TB screening and blood-pressure measurement) instead of relying on individuals visiting health facilities to be tested. However, the evidence base for how to deliver these services to test different populations is poor.

In a cluster randomized controlled trial in rural Lesotho the authors tested two different community approaches for delivering the same HIV testing and counselling services; in one individuals were offered the services in their homes, and in another services were offered at a mobile clinic that was set up at a community gathering. The study included 2563 participants and the authors found that uptake of HIV testing and counselling was higher for those offered home-based services compared to services at the mobile clinic (92.5% and 86.7%, respectively). By analysing this outcome by age the authors noted that there was a large difference in uptake among children END

The sense of smell uses fast dynamics to encode odors

Neuroscientists from the John B. Pierce Laboratory and Yale School of Medicine have discovered that mice can detect minute differences in the temporal dynamics of the olfactory system, according to research that will be published on December 16 in the open access journal PLOS Biology. The research team used light in genetically-engineered mice to precisely control the activity of neurons in the olfactory bulbs in mice performing a discrimination task. This approach to controlling neural activity, called optogenetics, allows for much more precise control over the activity ...

Introverts could shape extroverted co-workers' career success, OSU study shows

2014-12-16
CORVALLIS, Ore. - Introverted employees are more likely to give low evaluations of job performance to extroverted co-workers, giving introverts a powerful role in workplaces that rely on peer-to-peer evaluation tools for awarding raises, bonuses or promotions, new research shows. Introverts consistently rated extroverted co-workers as worse performers, and were less likely to give them credit for work performed or endorse them for advancement opportunities, according to two studies from researchers at Oregon State University, the University of Florida and University ...

This news release is available in German. This news release is available in German. Seeing - recognising - acting. These three words describe how a sensory input can lead to a targeted movement. However, very little is known about how and where the brain converts external inputs into behavioural responses. Now, scientists at the Max Planck Institute of Neurobiology in Martinsried have been able to shed light on important neural circuitry involved in the prey capture behaviour exhibited by young zebrafish. The findings show that neurons in the retina of the ...

Stay complex, my friends
2014-12-16
EAST LANSING, Mich. - The KISS concept ¬- keep it simple, stupid - may work for many situations. However, when it comes to evolution, complexity appears to be key for prosperity and propagating future generations. Research led by Michigan State University's BEACON Center for the Study of Evolution in Action shows that organisms sometimes have to use increasingly complex defenses to continue evading parasites' attacks and live longer than their simpler cousins. The results, published in the current issue of PLOS Biology, show how the virus-resistant hosts live better, ...

Bacterial 'bunches' linked to some colorectal cancers

2014-12-16
Researchers from Johns Hopkins have found that dense mats of interacting bacteria, called biofilms, were present in the majority of cancers and polyps, particularly those on the right side of the colon. The presence of these bacterial bunches, they say, may represent an increased risk for colon cancer and could form the basis of new diagnostic tests. Like tooth plaque and slime on pond stones, bacterial biofilms may coat the mucus layer of cells lining the colon, causing inflammation and some noncancerous bowel diseases. The bacteria "invade the layer of mucus that protects ...

US children are safer, better-educated, and fatter

2014-12-16
DURHAM, N.C. -- American children are generally safer and better-educated than they have been in 20 years, a new report from Duke University finds. Stubborn problems remain, including high rates of child poverty and a still-raging obesity epidemic, the 2014 National Child and Youth Well-Being Index Report notes. But "compared to 20 years ago, U.S. children are doing pretty well," said the report's lead author, Kenneth Land, the John Franklin Crowell Professor of Sociology at Duke. The report is based on the Duke Child Well-Being Index, a comprehensive measure of ...

Glacier beds can get slipperier at higher sliding speeds

Glacier beds can get slipperier at higher sliding speeds
2014-12-16
AMES, Iowa - As a glacier's sliding speed increases, the bed beneath the glacier can grow slipperier, according to laboratory experiments conducted by Iowa State University glaciologists. They say including this effect in efforts to calculate future increases in glacier speeds could improve predictions of ice volume lost to the oceans and the rate of sea-level rise. The glaciologists - Lucas Zoet, a postdoctoral research associate, and Neal Iverson, a professor of geological and atmospheric sciences - describe the results of their experiments in the Journal of Glaciology. ...

When pursuing goals, people give more weight to progress than setbacks

2014-12-16
New Year's resolution-makers should beware of skewed perceptions. People tend to believe good behaviors are more beneficial in reaching goals than bad behaviors are in obstructing goals, according to a University of Colorado Boulder-led study. A dieter, for instance, might think refraining from eating ice cream helps his weight-management goal more than eating ice cream hurts it, overestimating movement toward versus away from his target. "Basically what our research shows is that people tend to accentuate the positive and downplay the negative when considering how ...
