Introduction The knee in Parkinson’s disease (PD) patients is a problematic joint due to pain, stiffness and gait instability. The aim of this study is to evaluate the functional outcome and degree of pain relief achieved after total knee arthroplasty (TKA) in PD patients. Materials and methods This is a retrospective review of 26 PD patients (32 knees) with osteoarthritis who underwent a TKA between 1994 and 2013. Comorbidities, anesthetic procedures and complications were recorded. Patient functional status was assessed with the Knee Society Function Score (KFS) and the Knee Society Score (KSS). PD stage was classified with the Hoehn and Yahr Scale. Results The mean follow-up was 3.5 years (range 2–9). The mean age was 71 years (range 61–83) with a mean time since PD diagnosis of 11.8 years (range 4–24). PD severity on the Hoehn and Yahr Scale was 1.5 points before surgery and 2 points postoperatively. Pain on the visual analogic scale improved from 8 points preoperatively to 5 points at 1-year follow-up; function improved from 32 (range 20–45) to 71 (range 50–81) and from 34 (range 28–52) to 59 (range 25–76) on the KSS and KFS, respectively. The mean postoperative hospital stay was 9.8 days (range 5–21). Confusion and flexion contracture were the most frequent perioperative complications. Conclusion TKA successfully provided pain relief in PD patients. However, the functional outcome is related to disease progression and, therefore, variable. Perioperative complications are difficult to avoid and manage.

· Between 1989–2013, 69 Andean Condors (Vultur gryphus) were reintroduced in eight sites in the Andes of Colombia. Due to the lack of monitoring programs, little is known about the ecology and biology of these reintroduced populations. We present the first observations on a reintroduced breeding pair. For 36 months, we examined the breeding behavior of a pair of condors in a nest cave in the central Andes of Colombia. In June 2013, we observed a chick of about 6–7 months of age in the nest cave. The most remarkable outcomes of these observations are (1) that females spend more time guarding the chick whereas (2) males focus on guarding the nest cave. While the chick was in the nest cave (80 h of observations), the female was present in the vicinity of the nest cave and attended the chick for a longer time period than the male. However, in the absence of a chick or eggs (880 h of observations), the male was observed more often in the vicinity of the nest cave than the female. Nevertheless, we found no significant differences in vigilance patterns between the sexes. Intraspecific interactions of the Andean Condor with other raptors in the area were recorded during the observation period of this study. We make some predictions on the timing of reproduction of condors based on this reintroduced pair in Colombia and compare them with those reported elsewhere. Tracking released populations of condors is essential to ensure the positive impact of reintroduction efforts. Resumen · Comportamiento reproductivo de una pareja reintroducida de Cóndor Andino (Vultur gryphus) en la cordillera Central de Colombia Entre 1989–2013, 69 individuos de Cóndor Andino (Vultur gryphus) fueron liberados en ocho núcleos de repoblación en la región andina de Colombia. Debido a la falta de seguimiento de estas liberaciones, se conoce poco sobre la biología y ecología de la especie en esos núcleos de repoblación. Presentamos la primera información de seguimiento del comportamiento reproductivo de una pareja en los núcleos de repoblación. Por un periodo de 36 meses examinamos el comportamiento reproductivo de esa pareja en un nido encontrado en la cordillera Central de Colombia. En junio de 2013 registramos la presencia de un polluelo de aproximadamente seis a siete meses de edad en el nido. Mientras el polluelo estuvo en el nido (80 h de observación), la hembra permaneció dentro de la vecindad e interactuó por más tiempo con el polluelo en comparación con el macho. En ausencia de polluelo o postura (880 h de observación), el macho permaneció dentro del territorio por un mayor número de horas en comparación con la hembra, aunque estas diferencias no fueron estadísticamente significativas. Registramos interacciones interespecíficas directas entre el Cóndor Andino y rapaces que ingresaron a su área de anidación. El seguimiento de las poblaciones de cóndor liberadas es clave para garantizar el impacto positivo de los esfuerzos de reintroducción como herramienta para la conservación.

473 TÉCNICAS DENDROGEOMORFOLÓGICAS APLICADAS A LA CALIBRACIÓN DE MODELOS HIDRÁULICOS

RESUMEN La calibración de los modelos hidráulicos es un proceso complejo cuando existe escasez de datos de calados históricos, pero imprescindible para que los resultados del modelo sean verosímiles. Los datos procedentes del aná-lisis dendrogeomorfológico en árboles de la ribera del río Alberche a su paso por Navaluenga (Ávila), han permitido calibrar los parámetros de rugosidad de un modelo hidráulico bidimensional que se empleará para el análisis del riesgo por inundaciones en el núcleo urbano de este municipio. Palabras clave: Dendrogeomorfología, calibración, modelo hidráulico, ru-gosidad, Ávila. ABSTRACT The calibration of hydraulic models is a complex process when historical flood stages are not available, but essential to the model results were plau-sible. Data from dendrogeomorphological analysis of trees located on the banks of the Alberche river as it passes through Navaluenga village (Ávila) have enabled successfully calibrate roughness parameters of a two-dimen-sional hydraulic model that will be used for flood risk.

... Consequently, a reintroduction program was implemented between 1989 and 2013 and 71 individuals were released at eight repopulation sites (Sáenz-Jiménez, 2020). However, to date only one successful reproduction of the released condors was reported in Los Nevados Natural Park (Restrepo-Cardona et al., 2018). At present, little is known about the ecological requirements and survival of reintroduced individuals and the threats they may face, hindering the development of effective technical and financial strategies for their long-term conservation in the country. ...

... Patients with PD often have knee OA. The knee joint poses difficulties for PD patients in the advanced stages of the disease, causing pain, stiffness, and instability that may require TKA [93]. However, associated orthopedic conditions, such as a high risk of falls and fractures, rigidity, and poor bone quality in PD patients, can make THA challenging for arthroplasty surgeons [53,72]. ...
