Appearance concerns related to depression in patients with rheumatic disease
Patients with rheumatic disease can experience physical deformities, especially of the hands and feet in the case of rheumatoid arthritis (RA), or skin rashes and lesions and hand deformity in the case of systemic lupus erthyematosus. Few studies on body image concerns have been conducted, but research shows that women with lupus and RA have poorer body image than healthy women. A new study published in the March 2007 issue of Arthritis Care & Research examined the relationship between physical appearance concerns and psychological distress (depression and anxiety) in patients with RA and lupus.
Complications following hip replacement more common in obese patients, especially women
Obese patients tend to have a higher prevalence of total hip replacements due to a higher incidence of hip osteoarthritis. This is of particular concern in light of the trend in rising rates of obesity in developed countries. A new study published in the March 2007 issue of Arthritis Care & Research (http://www.interscience.wiley.com/journal/arthritiscare) evaluated the effects of obesity on complications and outcomes following total hip replacements and investigated whether the results differed in obese women and men. more

Eating ice cream may help women to conceive, but low-fat dairy foods may increase infertility risk
Drinking whole fat milk and eating ice cream appears to be better for women trying to become pregnant than a diet consisting of low-fat dairy products such as skimmed milk and yoghurt, according to new research published in Europe's leading reproductive medicine journal, Human Reproduction, today (28 February). more

Brain works more chaotically than previously thought; Information is not only transferred at synapses
The brain appears to process information more chaotically than has long been assumed. This is demonstrated by a new study conducted by scientists at the University of Bonn. The passing on of information from neuron to neuron does not, they show, occur exclusively at the synapses, i.e. the junctions between the nerve cell extensions. Rather, it seems that the neurons release their chemical messengers along the entire length of these extensions and, in this way, excite the neighbouring cells. The findings of the study are of huge significance since they explode fundamental notions about the way our brain works. more
