Over Half Of People With Rheumatoid Arthritis Have Periodontitis
Over half (56%) of people with rheumatoid arthritis (RA) also have periodontitis (a chronic inflammatory disease of the gum and surrounding ligaments and bones that hold the teeth in place), displaying fewer teeth than healthy matched controls, high prevalence of oral sites presenting dental plaque and advanced attachment loss (the extent of periodontal support that has been destroyed around a tooth) (chi square p

Antiretrovirals Can Be Used To Prevent Spread Of HIV/AIDS, Model Shows
In addition to acting as life-saving therapy to people living with HIV/AIDS, WHO researchers say antiretrovirals (ARVs) may also be able to prevent the spread of HIV, Health-e/allAfrica.com reports. Reuben Granich, of the WHO, used a model to estimate the use of ARVs for the prevention of HIV transmission, and presented his findings to delegates gathered at the 5th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention meeting in Cape Town, South Africa (Thom, 7/20).

Changing Perceptions About Student Drinking Reduces Alcohol Misuse

Giving students personalised feedback on their drinking behaviour and how it compares to social norms might help to reduce alcohol misuse, according to a Cochrane Systematic Review. A large body of social science research has established that students tend to overestimate the amount of alcohol that their peers consume. This overestimation causes many to have misguided views about whether their own behaviour is normal and may contribute to the 1.8 million alcohol related deaths every year. Social norms interventions that provide feedback about own and peer drinking behaviours may help to address these misconceptions. Researchers analysed data from 22 trials that together included 7,275 college and university students, mostly studying in the US. They found that students who were provided with personalised feedback via the internet or individual face-to-face sessions drank less often and indulged in less binge drinking than those in control groups. Web-based feedback also resulted in significant reductions in blood alcohol content and alcohol related problems. Group counselling and mailed feedback were not found to be effective compared to control interventions, although the researchers say further studies comparing the different ways of providing social normative feedback are required. "We can"t make direct comparisons between the different interventions, but based on a small number of studies web-based interventions would certainly seem to be a cost-effective option for reducing alcohol misuse," said lead researcher Maria Teresa Moreira, from the School of Health and Social Care at Oxford Brookes University in the UK. "We know that social norms have a powerful impact on thought and behaviour, so changing people"s perceptions about what is normal can really help. Most of the effects lasted for a few months, but some lasted over a year, particularly for the web-based feedback," added Moreira. Jennifer Beal Wiley-Blackwell
