Risk Factors of Muscle Wasting in Women with Rheumatoid Arthritis: Relevance of the Persistent Failure of Conventional Combination Therapy.

Background: Muscle wasting, also known as myopenia, is frequent in rheumatoid arthritis (RA). To date, it is still unknown if the failure of pharmacologic therapies increases the risk of myopenia in RA. Objective: To identify if treatment failure with conventional synthetic DMARDs (csDMARDs) constitutes an independent risk factor of muscle wasting in women with RA.

Serum irisin concentrations and osteoporotic vertebral fractures in women with rheumatoid arthritis: A cross-sectional study.

Irisin stimulates osteoblast differentiation increasing bone mass a decreasing in irisin levels might contribute to osteoporotic fractures in inflammatory diseases. To date, there is controverted whether irisin levels are associated with osteoporotic fractures in rheumatoid arthritis (RA). Therefore, we evaluate the association of serum irisin with osteoporotic Vertebral Fractures (VFs) in women with RA.

Description of Normative Spine TBS Data for Men and Women in Mexican Population.

Trabecular Bone Score (TBS) has proven its usefulness to improve areal Bone Mineral Density in diagnosing fracture risk and bone status evaluation. For it to be better interpreted, local reference values are recommended to account for population differences and, if possible, both in women and men, the former being scarcer. Using TBS, we reanalyzed data obtained from the Mexican population included in the Latin American Vertebral Osteoporosis Study and the Mexican Vertebral Study in men that included a random probability sample of 408 women and 414 men aged 50 and older without fractures.

Impact of osteoporosis-associated vertebral fractures on health-related quality of life in the Mexican population.

Objective: To measure the impact on the health-related quality of life (HRQoL) of a sample of Mexicans with vertebral fractures.

Material And Methods: One hundred fifteen subjects with vertebral fractures were interviewed and compared with 135 subjects similar in age without the fracture. Subjects were men and women > 50 years of age with osteoporosis confirmed by bone mineral densitometry and with at least 1 vertebral fracture verified by vertebral morphometry and Xrays.

The prevalence of vertebral fractures in San Juan, Puerto Rico: a population-based study among females aged 50 years and over.

Objective: The participation of Puerto Rico in the Latin American Vertebral Osteoporosis Study (LAVOS) has allowed us to study the magnitude of the problem of osteoporosis in the female population residing in San Juan. The objective of LAVOS was to estimate the prevalence of vertebral fractures in Latin American women using a random sample of females selected from cities across five Latin American countries.

Methods: A probability cluster design was employed to select a random sample of households in San Juan, Puerto Rico, in order to interview 400 females aged 50 years and over.

Fracture risk assessment in Latin America: is Frax an adaptable instrument for the region?

Osteoporosis is a generalized disease of bone that increases fracture risk. Multiple factors influence this risk, besides low bone mass. To decrease osteoporotic fractures, those patients who require preventive management should be readily identified.
