It takes 2 to infect

Two so-called invasion proteins are crucial for infection. Each binds a specific receptor on the surface of human cells, which stimulates the host cell to take up the pathogen. Normally, these receptor molecules exert a different function, for example the regulation of cell growth and wound healing. The group's results have now been published in the current issue of the "Journal of Molecular Biology". more  

Hospital noise initiative reduces average peak decibel levels by 20 percent

Patients often complain that getting a good night's sleep or a bit of peace and quiet in hospital can be difficult. But a study published in the December issue of the Journal of Clinical Nursing has shown that adopting some simple measures can reduce peak noise levels on hospital wards by just under 20 per cent. more

Panel of multiple sclerosis experts provides best practice treatment recommendations for Tysabri

Best-practice recommendations for the selection and management of patients with multiple sclerosis (MS) who may benefit from, or are receiving treatment with TYSABRI® (natalizumab) were published today in a supplement to the medical journal Multiple Sclerosis. The panel provided recommendations focusing on appropriate patient selection and patient management. The recommendations, which recognize the significant efficacy of TYSABRI and the need to adequately treat patients who exhibit continued disease activity, are based on U.S. prescribing information and the panel's vast clinical experience in treating MS patients with TYSABRI. Recommendations not only take into account the need to adequately treat patients who exhibit continued disease activity, but also the need to weigh the treatment's benefit with potential risks. more  

Smart phones allow quick diagnosis of acute appendicitis

Radiologists can accurately diagnose acute appendicitis from a remote location with the use of a handheld device or mobile phone equipped with special software, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). more

Elastography reduces unnecessary breast biopsies  

Elastography is an effective, convenient technique that, when added to breast ultrasound, helps distinguish cancerous breast lesions from benign results, according to an ongoing study presented today at the annual meeting of the Radiological Society of North America (RSNA). more

Unindicated CT series result in unnecessary radiation exposure for patients  

A large proportion of patients who undergo abdominal/pelvic computed tomography (CT) receive unindicated and unnecessary additional image acquisition resulting in excess, avoidable radiation exposure, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). more

Patients say 'no thanks' to risky medical treatments

A recent study suggests that increasing patient responsibility for making medical decisions may decrease their willingness to accept risky treatment options. Details of this proof-of-concept study appear in the December issue of Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology. more
