Cross-cultural adaptation and validation of the Spanish version of the Oswestry disability index for Mexican population.

PURPOSE: This study aimed to adapt a Spanish translation of the Oswestry Disability Index (ODI) into a cross-cultural version for the Mexican population. The objectives were to verify the validity and reliability of the adapted ODI and to compare pain perception between patients with and without obesity. MATERIAL AND METHODS: We included 102 patients with low back pain from two neurosurgery departments in Mexico. The ODI questionnaire was translated and culturally adapted. Validity and construct were evaluated using exploratory factor analysis, and the external convergent validity was assessed by correlating ODI scores with pain intensity, age, and obesity. Test-retest reliability was calculated using the intraclass correlation coefficient, and confirmatory analysis was employed to validate the factorial structure. RESULTS: Patients with obesity were older and had higher pain scores than patients without obesity. The exploratory analysis of the ODI in Mexican Spanish showed good reliability (Cronbach's alpha of 0.923) and validity (factorial loading range, 0.681 - 0.818). The confirmatory analysis showed almost null or very low discrepancy between the proposed model and the real data. CONCLUSIONS: A Spanish translation of ODI was cross-culturally adapted for the Mexican population. The Mexican version of the ODI showed good reliability and validity in Mexican culture.

The Oswestry Disability Index (ODI) is a widely used tool to measure physical disability in daily activities due to low back pain.A Spanish-language version has not been culturally adapted and validated for Mexican habits and lifestyle.This study describes the process of the Spanish ODI translation and cultural adaptation, showing it is a reliable and valid tool for assessing disability in patients with low back pain, with a good factorial structure.

Nutrition, Healthcare Benefits and Phytochemical Properties of Cassava (Manihot esculenta) Leaves Sourced from Three Countries (Reunion, Guinea, and Costa Rica).

(1) Background: Manihot esculenta, cassava, is an essential food crop for human consumption in many parts of the world. Besides the wide use of its roots, cassava leaves have been used locally as green vegetables and for medicinal purposes. However, nutritional health data regarding cassava leaves is limited, therefore we investigated its composition and associated potential bioactivity interest for human health. (2) Methods: Cassava leaf bioactivity investigations focused on antioxidant properties (free radical scavenging) in association with immunomodulatory activities on inflammatory murine macrophages to measure the impact of cassava extract on the production of pro-inflammatory cytokines such as Interleukin-6, Tumor Necrosis Factor alpha, Monocyte Chemoattractant Protein-1, Prostaglandin-E2 and mediators such as nitric oxide. (3) Results: Antioxidant and immunomodulatory bioactivities were significant, with a concentration-dependent inhibition of cytokines production by inflammatory macrophages; (4) Conclusions: Taken together, our results tend to suggest that Manihot esculenta leaves might be underrated regarding the potential nutrition-health interest of this vegetal matrix for both human nutrition and prophylaxis of metabolic disease with underlying low grade inflammation status.

Antioxidative and Immunomodulatory Potential of the Endemic French Guiana Wild Cocoa "Guiana".

Guiana is a little-known and endemic variety of cocoa (Theobroma cacao L.), native to French Guiana. No data were available regarding its chemical composition and biological properties; therefore, a study was necessary, using Forastero as a reference. To exemplify biological activities of the cacao species, cocoa extracts were evaluated by antioxidant (DPPH, FRAP, ORAC) and anti-inflammatory assays. Our results showed that raw Guiana presented equivalent DPPH and FRAP activities, but a 1.3-fold higher antioxidant activity (1097 ± 111.8 µM ET/g DM) than Forastero (838.5 ± 67.8 µM ET/g DM) in ORAC assay. Furthermore, the impact of fermentation (under four conditions: unfermented, two days, four days and six days of fermentation) on Guiana cocoa beans composition and health properties was also studied. Indeed, fermentation, a key step necessary to obtain the taste and color of chocolate, is generally known to alter bean composition and modulate its health benefits. At six days, the fermentation process led to a nearly 25% lower antioxidative capacity in various assays. Moreover, in inflammation-induced macrophage assays, Guiana and Forastero unfermented extracts induced a 112% stimulation in TNF-α production, and a 56.8% inhibition of IL-6 production. Fermentation altered the cocoa composition by diminishing bioactive compounds, which could be responsible for these biological activities. Indeed, after six days of fermentation, compounds decreased from 614.1 ± 39.3 to 332.3 ± 29 mg/100 g DM for epicatechin, from 254.1 ± 14.8 to 129.5 ± 20.7 mg/100 g DM for procyanidin B2 and from 178.4 ± 23.5 to 81.7 ± 2.9 mg/100 g DM for procyanidin C1. The similar composition and the equivalent or higher antioxidant activity of Guiana leads us to propose it as an alternative to Forastero.
