RESUMO
INTRODUCTION: Low back pain (LBP) is the leading cause of years lived with disability worldwide. Higher levels of catastrophizing were found in patients with LBP and this variable is associated with self-reported disability. The Pain Catastrophizing Scale (PCS) is a self-report questionnaire that assesses catastrophizing in the presence of pain. Currently, an Argentine version of the PCS is not available. OBJECTIVE: To translate and cross-culturally adapt the PCS into Argentine Spanish and test the psychometric properties of the new version with chronic LBP patients. STUDY DESIGN: Study of diagnostic accuracy/assessment scale. METHODS: The study was carried out in three consecutive phases following the COSMIN guidelines: translation, cross-cultural adaptation and validation. We included Argentine residents over 18 years with chronic LBP. We used the PCS and the Global rating of change (GROC) to assess the psychometric properties. RESULTS: No difficulties were present in the translation processes and the PCS-Arg was developed. The alfa Cronbach coefficient was 0.89. The standard error of measurement and the minimal detectable change were 5.4 and 15.1 points, respectively. In the explanatory factorial analysis 3 components were identified. For the construct validity, the correlation between the PCS-Arg and disability and pain were r = 0.35 and rho = 0.04, respectively. The mean PCS score was 29.9. The lowest and highest scores were 3 and 52 points, therefore, no roof or ceiling effects of the total score were observed. CONCLUSION: The PCS-Arg is a viable, reliable and valid tool for the assessment of catastrophizing in patients with chronic LBP.

RESUMEN Objetivo: Describir las características demográficas y la proporción de sujetos sometidos a cirugía cardiovascular (CCV), que requieren ventilación mecánica prolongada (VMP) y analizar los factores asociados al desarrollo de dicha entidad. Materiales y método: Serie de casos. Se incluyeron sujetos mayores de 18 años que requirieron una CCV a través de esternotomía, entre julio de 2017 y noviembre de 2018. Se excluyeron sujetos con datos faltantes y se eliminaron quienes fallecieron durante la cirugía. Se llevó a cabo un análisis de regresión logística para determinar las variables predictoras de la ocurrencia de VMP. Resultados: De 70 sujetos analizados, 17,1% requirió VMP, cuya mortalidad fue de 41,7%. En el análisis univariado la obesidad, días de internación, tiempo de cirugía, necesidad de circulación extracorpórea (CEC), desarrollo de complicaciones posoperatorias (POP) y puntaje del score Sequential Organ Failure Assessment (SOFA) en el posquirúrgico inmediato, se asociaron significativamente a VMP. Conclusión: La proporción de sujetos con requerimiento de VMP fue superior a lo reportado en la literatura. El tiempo de cirugía, el SOFA en el POP inmediato, obesidad, necesidad de CEC, días de internación y desarrollo de complicaciones POP se asociaron con VMP.
ABSTRACT Objective: To describe the demographic characteristics and proportion of postoperative cardiovascular subjects who require prolonged mechanical ventilation (PMV) and to analyze associated factors. Materials and method: A case series study was conducted on subjects over 18 years of age who required cardiac surgery via median sternotomy between July 2017 and November 2018. Subjects with missing data were excluded, and subjects who died during surgery were eliminated. A logistic regression analysis was performed to identify predicting factors associated with PMV. Results: Of the 70 subjects analyzed, 17.1% required PMV, with a mortality of 41.7%. In the univariate analysis, obesity, length of hospital stay, duration of surgery, need of extracorporeal circulation, postoperative complications, and sequential organ failure assessment (SOFA) scores in the immediate postoperative period were significantly associated with PMV. Conclusion: The proportion of subjects requiring PMV was higher than the reported in the literature. The duration of surgery, obesity, need of extracorporeal circulation, length of hospital stay, postoperative complications, and SOFA scores in the immediate postoperative period were associated with PMV.
RESUMO
RESUMEN Objetivo: Determinar la prevalencia de estudios complementarios (EC) en sujetos con afecciones de columna que acuden al Servicio de Kinesiología de un hospital público de la Ciudad Autónoma de Buenos Aires. Como objetivos secundarios, nos planteamos calcular costos directos producto de los EC en sujetos con dolor lumbar (DL), dolor cervical (DC) y prevalencia de banderas rojas en DL. Materiales y método: Estudio transversal. Se incluyeron sujetos con afección de columna vertebral, mayores de 18 años y que firmaron el consentimiento informado. Resultados: La prevalencia de EC para la población general fue de 83%. El 87,5% de los sujetos con DL presentó al menos una bandera roja. El costo total de los EC fue de $210133 (US$3431) y el costo promedio por sujeto fue de $1129 (US$18) en la población general. Conclusión: La prevalencia de EC de los sujetos con afecciones de columna fue del 83%, lo que generó un costo promedio de $1129 (US$18) por sujeto. Al evaluar la presencia de banderas rojas, el 87,5% de los sujetos con DL presentó al menos una.
ABSTRACT Objective: The primary objective was to determine the prevalence of imaging in subjects with spine conditions admitted to the physical therapy unit of a public hospital in the Autonomous City of Buenos Aires. The secondary objective was to estimate the direct imaging-related costs in subjects with low-back pain (LBP), neck pain (NP), and prevalence of red flags in LBP. Materials and method: A cross-sectional study was conducted on >18-year-old subjects with spine conditions who signed a written informed consent. Results: Prevalence of imaging was 83%. Prevalence of red flags was 87.5% in LBP subjects. The total cost of imaging reached US$3431, and the average cost per subject was US$18. Conclusion: Prevalence of imaging in subjects with spine conditions was 83%, resulting in an average cost of US$18 per subject. In patients with LBP 87,5% presented at least one red flag.
