Urban slum conditions are a source of leptospirosis
A study conducted in an urban slum setting in Salvador, Brazil has found that open sewers, accumulations of refuse, and inadequate floodwater drainage are acting as sources for transmission of the disease leptospirosis. The study is published in this week's PLoS Neglected Tropical Diseases. view more (2008-04-23)
Learning from copper
Video conferencing is on the rise. But the diverse options for the transmission of images and sound may be confusing. Thanks to SDSL, the project "digital classroom at the sickbed" shows how maximum performance is obtained using the existing copper wire infrastructure. Whatever the OECD Program for International Students Assessment might say,... view more... (2002-03-05)
People are unlikely to withdraw consent for genetic research
People are unlikely to withdraw consent for genetic research even when samples were taken many years ago, research in this week's BMJ suggests. In 1990 1583 randomly selected people in Sweden donated blood to a World Health Organisation project researching cardiovascular disorders and diabetes. Eleven years later, doctors sought their consent for... view more... (2002-09-18)
Researchers find natural section favors parasite fitness over host health
Why do parasites harm their hosts? Classic evolutionary theory predicts that parasites become more virulent because they must transmit themselves between hosts, yet scientists have found little data to support this idea, until now. view more (2008-05-13)
Researchers identify key step bird flu virus takes to spread readily in humans
Since it first appeared in Hong Kong in 1997, the H5N1 avian flu virus has been slowly evolving into a pathogen better equipped to infect humans. The final form of the virus, biomedical researchers fear, will be a highly pathogenic strain of influenza that spreads easily among humans. view more (2007-10-05)
Predictive genetic tests range from highly useful to potentially harmful
Predictive genetic testing has the potential to save lives through targeted surveillance and preventive measures, but a paper in this week's BMJ reports that most genetic tests carry a degree of uncertainty, which limits their usefulness and, in some cases, can even be harmful to patients. For some diseases, predictive genetic testing is highly... view more... (2001-04-24)
Insects and disease - international symposium and national meeting
The Royal Entomological Society, in association with the Entomological Society of the Netherlands and the International Union of Forest Research Organisations, is holding its bi-annual symposium at the University of Aberdeen on 10-12 September 2001. The theme of "Insects and disease" will bring together hundreds of entomologists from... view more... (2001-08-13)
Most UK citizens susceptible to hepatitis B infection
The failure of the UK to introduce universal hepatitis B immunisation means that most UK citizens are susceptible to infection, warns an infectious diseases expert in this week's BMJ. view more (2007-11-12)
Controlling schistosomiasis: buffalo or snails?
A parasitic infection common in China and Southeast Asia could be effectively reduced by controlling snail populations, according to research published in PLoS Medicine. view more (2008-01-22)
Patients at greater risk if mother has coronary heart disease
If your mother has coronary heart disease (CHD), you may want to make an extra effort to combat your personal risk. view more (2006-04-28)
Press release ANRS, INSERM, AFSSAPS
Adverse events that were unknown so far, have recently been observed in France in children who had been exposed to antiretroviral drugs (nucleosidic inhibitors of the reverse transcriptase) during intra uterine life and postnatally to prevent mother to child transmission of HIV. The children suffer from mitochondrial dysfunctions. The mitochondry... view more... (1999-06-25)
Sugar identified as key to malaria parasite invasion
Researchers at the Johns Hopkins Malaria Research Institute (JHMRI) have identified a sugar in mosquitoes that allows the malaria-causing parasite, Plasmodium falciparum, to attach itself to the mosquito's gut. view more (2007-09-11)
International study investigates early biology of HIV infection
In July 2005, the race to find a vaccine that would stem the worldwide rate of 13,000 new cases of HIV infection each day moved from competition among research institutions to a strategy of cooperation. view more (2006-05-02)
Not enough is known about treating malaria in pregnancy, researchers say
Few studies compare the effects of different drug regimes in pregnant women, and many of the best studies were conducted in Southeast Asia, where malaria transmission rates are low, says researcher Lois Orton of the University of York in England. view more (2005-07-20)
Blood transfusion-transmitted infections: A global perspective
Thanks to the many blood-safety interventions introduced since 1984, the overall risk for most transfusion-transmitted infections has become exceedingly small. view more (2006-09-28)
Primary care practitioners need to become genetically literate
Increasing availability of DNA based tests and demand by patients for genetic information and advice mean that primary care practitioners will need to become genetically literate. A paper in this week's BMJ discusses the implications of genetic advances for primary care. Currently, the most important elements for primary care are prediction of... view more... (2001-04-24)
Success comes at a cost, even for phages
As many a mother may tell you, expending the energy necessary to raise a clutch of kids can shave years off one's life. Trade-offs between reproductive success and survival have been demonstrated for a wide variety of organisms, in keeping with life history theory. view more (2006-06-13)
Can the tonsils influence oral HIV transmission?
Current research demonstrates that the tonsils may possess the necessary factors to act as a transmission site for the spread of HIV. view more (2007-07-26)
War between the sexes influences evolution in some species, say scientists
Competition and conflict between males and females start inside the egg in some species, say scientists. view more (2006-04-07)
Agricultural antibiotic use contributes to 'super-bugs' in humans
Doctors have become increasingly concerned by the problem of "super-bugs"-bacteria that have become resistant to standard antibiotics. It is well known that a high rate of antibiotic prescribing in hospitals contributes to the emergence of drug resistant bacteria. view more (2005-07-05)
