[Lower limb ischemia in giant cell arteritis. Report of one case].
Giant cell arteritis is more common in women older than 60 years, is associated with systemic inflammation symptoms and mainly involves the aortic arch and cranial arteries, specially the temporal artery. Symptomatic lower extremity arterial stenosis or occlusion is uncommon and can lead to limb loss. We report a 73-year-old woman presenting with a one-month history of lower extremity intermittent claudication of sudden onset. ⋯ Steroidal treatment was started, and a temporal artery biopsy was performed confirming giant cell arteritis. Six weeks after steroid therapy the patient had a complete remission of symptoms. A serologic exacerbation was subsequently treated with a humanized monoclonal antibody against the interleukin-6 receptor Tocilizumab, obtaining long time remission.

[Prevalence of cholelithiasis and gallbladder cancer among Aymara individuals].
The prevalence of cholelithiasis and gallbladder cancer may be different across ethnic groups. ⋯ There is a 42% prevalence of cholelithiasis and no gallbladder cancer in this sample of Aymara population.

The assessment of frailty among older people could help to reduce its social and health burden. ⋯ The prevalence of frailty increased markedly with age. It is important to implement prevention strategies to allow an early identification of high-risk individuals.

[The general self-efficacy scale (GSES): Reevaluation of its reliability and validity evidence in Chile].
Self-efficacy is a psychological variable closely related to healthy behaviors. One of the most widely used instruments to measure this variable is the general self-efficacy scale (GSES). In Chile, the only psychometric study of this scale has important analytical limitations. ⋯ The GSES is an adequate scale to measure general self-efficacy in the Chilean population and allows unbiased comparisons based on sex or age.

[Equations to estimate body composition using bioelectrical impedance in Chilean adults].
Equations for the evaluation of fat-free mass (FFM) and fat mass (FM) with Bioelectrical impedance analysis (BIA) were formulated in Caucasian populations. International recommendations suggest that population-specific equations should be formulated. ⋯ Both equations behave similarly and have biases, although less with Schifferli. Statistically correcting for biases, the new adjusted equations provide clinically valid estimates of FFM and FM. Equations should not only be population-specific, but also device-specific.
