Mathematical modelling of cytokine-mediated inflammation in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory disease preferentially affecting the joints and leading, if untreated, to progressive joint damage and disability. Cytokines, a group of small inducible proteins, which act as intercellular messengers, are key regulators of the inflammation that characterizes RA. They can be classified into pro-inflammatory and anti-inflammatory groups.

Excess non-spine fractures in women over 50 years with celiac disease: a cross-sectional, questionnaire-based study.

The association of celiac disease with fracture is controversial. Recent studies may have underestimated the impact by studying patients with low fracture risk. Since postmenopausal women are at greatest risk of fracture, we have investigated non-spine fracture occurrence in women > or =50 years with celiac disease.
