Body composition evaluated by body mass index and bioelectrical impedance vector analysis in women with rheumatoid arthritis.

Background: Rheumatoid arthritis (RA) is a complex inflammatory disease that modifies body composition. Although body mass index (BMI) is one of the clinical nutrition tools widely used to assess indirectly nutritional status, it is not able to identify these body alterations. Bioelectrical Vector Analysis (BIVA) is an alternative method to assess hydration and body cell mass of patients with wasting conditions.

Total Hip Arthroplasty Outcomes: An 18-Year Experience in a Single Center: Is Systemic Lupus Erythematosus a Potential Risk Factor for Adverse Outcomes?

Background: In patients with systemic lupus erythematosus (SLE), persistent joint activity and treatment with glucocorticoids are associated with musculoskeletal complications. About 30% of these patients become candidates for surgical treatment. The aim of this study was to evaluate postoperative outcomes after total hip arthroplasty (THA) in SLE patients.
