Younger people, men and those without children more likely to drop out of HIV care in South Africa

2014-02-21
(Press-News.org) Analysis carried out by an academic at Royal Holloway, University of London has revealed that younger people, men and those without children are more likely to stop attending clinics for HIV treatment in South Africa.

Dr Michael Evangeli, from the Department of Psychology at Royal Holloway, worked alongside colleagues at the University of Southampton and the University of KwaZulu Natal, South Africa. The academics used data collected in a study, which is published in the journal PLOS ONE, that followed the progress of 380 HIV positive people eligible for HIV treatment in a rural part of South Africa over a four year period and looked at what was associated with whether they dropped out of care.

Dr Evangeli, lead author of the study, said: "There is a pressing need to engage young people, and men, in long-term care. Medication for HIV is only given to those who are most unwell and they need to attend clinics regularly. Failing to attend is a problem for both the health of these individuals and for the health of others whom they may put at risk of HIV infection."

South Africa has the largest HIV positive population in the world – around six million people. One in five adults in South Africa are HIV positive.

"We need to improve our understanding of retention in care in future studies. Ultimately strategies must be put in place to help people remain in care and get the treatment they so desperately need to help slow down the spread of HIV and save as many lives as possible," added Dr Evangeli.

CNIO team explains lower cancer incidence rate in patients with central nervous system disesase

CNIO team explains lower cancer incidence rate in patients with central nervous system disesase
2014-02-21
Epidemiological studies demonstrate that diseases of the central nervous system such as Alzheimer, Parkinson and schizophrenia protect against cancer. The most remarkable example is Alzheimer's disease, which can reduce the risk of suffering from cancer by up to 50%. Various theories have been put forward in an attempt to explain this relationship between diseases at a first glance seem to be so different from the pharmacological, genetic and environmental perspectives. However, the available results were not consistent enough to confirm these models. Alfonso Valencia, ...

NASA researcher finds planet-sized space weather explosions at Venus

NASA researcher finds planet-sized space weather explosions at Venus
2014-02-21
Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, can be so large at Venus that they're bigger than the entire planet and they can happen multiple times a day. "Not only are they gigantic," said Glyn Collinson, a space scientist at NASA's Goddard Space Flight Center in Greenbelt, Md. "But as Venus doesn't have a magnetic field to protect itself, the hot flow anomalies happen right on top of the planet. ...

New apps may help detect seizures, treat strokes

2014-02-20
PHILADELPHIA – Two new smart phone applications may help people detect epileptic seizures and get better stroke treatment, according to two studies released today that will be presented at the American Academy of Neurology's 66th Annual Meeting in Philadelphia, April 26 to May 3, 2014. In the first study, an epilepsy app was designed to help non-doctors determine if a person is having an epileptic seizure. "It can often be difficult to determine whether someone is having an epileptic seizure," said study author Victor Patterson, MD, a neurologist from Belfast, UK. ...

Western University primatologist teams with international group to save lemurs

2014-02-20
Lemurs, the most endangered mammal group on Earth, represent more than 20 per cent of the world's primates. Native only to Madagascar, more than 90 percent of the species are threatened with extinction. A Western University primatologist has teamed with 18 lemur conservationists and researchers, many of whom are from Madagascar or have been working there for decades, to devise an action plan to save Madagascar's 101 lemur species. The action plan contains strategies for 30 different priority sites for lemur conservation and aims to help raise funds for individual projects. ...

Vibration energy the secret to self-powered electronics

2014-02-20
MADISON — A multi-university team of engineers has developed what could be a promising solution for charging smartphone batteries on the go — without the need for an electrical cord. Incorporated directly into a cell phone housing, the team's nanogenerator could harvest and convert vibration energy from a surface, such as the passenger seat of a moving vehicle, into power for the phone. "We believe this development could be a new solution for creating self-charged personal electronics," says Xudong Wang, an assistant professor of materials science and engineering at the ...

Study in mice raises question: Could PTSD involve immune response to stress?

2014-02-20
COLUMBUS, Ohio – Chronic stress that produces inflammation and anxiety in mice appears to prime their immune systems for a prolonged fight, causing the animals to have an excessive reaction to a single acute stressor weeks later, new research suggests. After the mice recovered from the effects of chronic stress, a single stressful event 24 days later quickly returned them to a chronically stressed state in biological and behavioral terms. Mice that had not experienced the chronic stress were unaffected by the single acute stressor. The study further showed that immune ...

Nanoscale pillars could radically improve conversion of heat to electricity

Nanoscale pillars could radically improve conversion of heat to electricity
2014-02-20
University of Colorado Boulder scientists have found a creative way to radically improve thermoelectric materials, a finding that could one day lead to the development of improved solar panels, more energy-efficient cooling equipment, and even the creation of new devices that could turn the vast amounts of heat wasted at power plants into more electricity. The technique—building an array of tiny pillars on top of a sheet of thermoelectric material—represents an entirely new way of attacking a century-old problem, said Mahmoud Hussein, an assistant professor of aerospace ...

Developing countries face 'leading medical scourge of developed countries'

2014-02-20
(Garrison, NY) Chronic illness, already a major and expensive problem in developed countries, is rapidly increasing in developing countries, adding to the longstanding burden caused by high rates of infectious diseases. However, poor countries will not be able to afford the costly medical technologies that wealthy countries use to treat chronic conditions, including heart disease, stroke, cancer, pulmonary disease, and diabetes, writes Daniel Callahan, cofounder of The Hastings Center. Callahan examines this trend and concludes that it calls for a new, more economically ...

Long-term daily multivitamin supplement use decreases cataract risk in men

2014-02-20
SAN FRANCISCO – Feb. 20, 2014 – Long-term daily multivitamin supplement use may lower cataract risk in men, according to a study of nearly 15,000 male physicians published this month in Ophthalmology, the journal of the American Academy of Ophthalmology. Past observational studies have indicated a relationship between nutritional supplement use and eye health. However, randomized trial data on the effects of long-term multivitamin supplement use and risk of eye diseases are limited and, in some cases, non-existent. To address this, researchers based at Brigham and Women's ...

Extreme weather decides distribution of insects

Extreme weather decides distribution of insects
2014-02-20
As climate change is progressing, the temperature of our planet increases. This is particularly important for the large group of animals that are cold-blooded (ectothermic), including insects. Their body temperature is ultimately determined by the ambient temperature, and the same therefore applies to the speed and efficiency of their vital biological processes. But is it changes in average temperature or frequency of extreme temperature conditions that have the greatest impact on species distribution? This was the questions that a group of Danish and Australian researchers ...
