    Background: Patients with rheumatoid arthritis are recognized as being at risk for osteoporosis as a result of the disease process as well as the medication used to treat it. This study was conducted to consider the use of calcaneal scanning with quantitative ultrasound—contact ultrasound bone analysis (CUBA)—to diagnose osteoporosis in patients with rheumatoid arthritis.Methods: Forty-six patients (11 men and 35 women) with established rheumatoid arthritis underwent dual-energy x-ray absorptiometry (DEXA) of the nondominant wrist andCUBA of the nondominant heel. Sensitivity, specificity, and positive and negative predictive values were used to determine the correlation between osteoporosis as diagnosedby the CUBA heel scan compared with the DEXA wrist scan given that DEXA is widely seen as the gold standard for the diagnosis of osteoporosis.Results: The CUBA heel scan revealed a sensitivity of 90% and a specificity of 44% for a diagnosis of osteoporosis compared with DEXA. The positive predictive value of theCUBA scan was 31%, and the negative predictive value was 94%. Therefore, if normal bone density is found using CUBA, there is 94% certainty this is correct. However, if osteoporosis is diagnosed using CUBA, there is only 31% certainty this is correct. In such instances a secondary scan using a different method (eg, DEXA) would be required. Future work should consider the effect of minor alterations to the equipment or scanning protocol, because this may improve diagnosis.Conclusions: The CUBA unit could be used as a primary screening device. Given the cost and accessibility issues associated with DEXA, quantitative ultrasound may have arole in screening for osteoporosis in the primary-care setting to determine the most appropriate routes of referral for patients requiring further investigations. <br/

    “Dancing the Orishas: Exporting a Constructed Form of Popular Culture from Havana to Arcata” The staged sacred and social dances of the Afro-Cuban community were chosen to represent the new “revolutionary identity” of Cuba. Maya J. Berry writes about this phenomenon in her essay, “From ‘Ritual’ to ‘Repertory’: Dancing to the Time of the Nation” in the Afro-Hispanic Review. This paper builds on that work. First, it defines a bodily archives a performed identity. Constructed by the Conjunto Folklorico Nacional de Cuba (CFN), Compania Raices Profundas, Cutumba and Ballet Folklorico Afro-Cubano, this archives created the revolutionary identity. Through these dance companies\u27 methods of “folklorization,” a “classical-folkore” repertory and training was created. Second, this paper seeks to understand the ways this “classical-folklore” has been exported from Cuba and influenced the Diaspora dance movement in the United States. An example of its export takes place in the “Explorations in Afro-Cuban Drum and Dance” workshop which takes place in Arcata, California perpetuates the classical Afro-Cuban training outside of Cuba and is central to this study of Popular dance
