Background: Neuropathic pain can be overlooked in cancer patients. The advent of screening tools can help in recognizing it. However, little is known about their relative diagnostic performance and factors that affect it. This study evaluated the prevalence of neuropathic pain using several diagnostic strategies in cancer patients undergoing chemotherapy. Methods: Patients attending the Oncology Unit of the investigators' site to continue their chemotherapy schedule were systematically screened for this cross-sectional study. Before starting chemotherapy drugs, pain specialists made a clinical diagnosis of neuropathic pain (either disease related, treatment related or comorbid) and medical oncologists administered three validated screening tools. Their relative diagnostic performance and the impact of some pain features on it were analysed using multivariate statistical methods. Results: From a total of 358 patients, 194 (54.2%) suffered from pain and 73 (20.4%) had a clinical diagnosis of pure neuropathic or mixed pain. Among the screening tools, the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) was more specific (93.4%), although less sensitive (68.1%) than the Douleur Neuropathique in 4 Questions (DN4) (sensitivity: 87.5%, specificity: 88.4%). Interestingly, the specificities of these two instruments did not differ in patients with mild pain, while the DN4 remained to be more sensitive than the LANSS regardless of pain severity. Conclusions: Neuropathic pain is common in cancer patients undergoing chemotherapy. The DN4 might be of great help for the early detection of patients at risk because of incipient chemotherapy-related neuropathies and the LANSS to rule out neuropathic pain in patients with complex pain conditions.

El presente artículo busca identificar los estilos de aprendizaje que se observan en los estudiantes de la etnia wayuu, de las universidades públicas del departamento de la Guajira, Colombia. En el contexto metodológico, el estudio se caracteriza como descriptivo con enfoque cuantitativo. La muestra estuvo constituida por 210 estudiantes seleccionados mediante un muestreo intencional, de las instituciones: Universidad de la Guajira (Uniguajira) y Universidad Nacional Abierta y a Distancia (UNAD). Los resultados demuestran que los estilos de aprendizaje predominantes, son: activo, reflexivo y pragmático; y en menor proporción, se hace presente el estilo teórico. Se concluye que los estilos de aprendizaje no resultan excluyentes entre sí, ya que puede producirse una combinación o alternancia de estos, con el fin de lograr el aprendizaje de alto valor en diferentes momentos, contextos o circunstancias.
