In Heracles Mainomenos, by Euripides, the hero is submited to the ultimate test: win himself, accepting stay alive after committing an irremediable error. The dramatic action has dual motivation, human and divine. The human conflict requires resilience of families and friends of Heracles and the opposition of Lico is a key element to the action. In the subsequent clash between Heracles and the goddess Hera, victory lies with the deity, motivating the disaster, but confirms the heroics of Heracles, that resists the urge to annihilation after the murder of children. His friend, King Theseus, provides him the support needed to dissuade him from his purpose of annihilation and strengthens him for endurance. The valuation of philia is an important element in shaping the sense of this euripidean text.

En la pieza Heracles Furioso, de Eurípides, el héroe se somete a la prueba definitiva: vencerse a sí mismo, aceptar seguir con vida después de cometer un error irremediable. La acción dramática tiene doble motivación, humana y divina. El conflicto humano requiere capacidad de resistencia de la familia y amigos de Heracles y la oposición de Lico es un elemento clave para la acción. En el enfrentamiento posterior entre Heracles y la diosa Hera, la victoria corresponde a la deidad, motivando a la catástrofe, pero se confirma la heroicidad de Heracles, que se resiste a la tentación de aniquilación tras el asesinato de sus niños. Su amigo, el rey Teseo, le proporciona el apoyo necesario para disuadirle de su propósito de aniquilamiento y fortalece al héroe decaído para la resistencia. La valoración de philia es un elemento importante en la constitución de la significación del texto de Eurípides

STUDY DESIGN: The inflammatory responses of primary human intervertebral disc (IVD) cells to tumor necrosis factor α (TNF-α) and an antagonist were evaluated in vitro. OBJECTIVE: To investigate an ability for soluble TNF receptor type II (sTNFRII) to antagonize TNF-α-induced inflammatory events in primary human IVD cells in vitro. SUMMARY OF BACKGROUND DATA: TNF-α is a known mediator of inflammation and pain associated with radiculopathy and IVD degeneration. sTNFRs and their analogues are of interest for the clinical treatment of these IVD pathologies, although information on the effects of sTNFR on human IVD cells remains unknown. METHODS: IVD cells were isolated from surgical tissues procured from 15 patients and cultured with or without 1.4 nmol/L TNF-α (25 ng/mL). Treatment groups were coincubated with varying doses of sTNFRII (12.5-100 nmol/L). Nitric oxide (NO), prostaglandin E₂ (PGE₂), and interleukin-6 (IL6) levels in media were quantified to characterize the inflammatory phenotype of the IVD cells. RESULTS: Across all patients, TNF-α induced large, statistically significant increases in NO, PGE₂, and IL6 secretion from IVD cells compared with controls (60-, 112-, and 4-fold increases, respectively; P < 0.0001). Coincubation of TNF-α with nanomolar doses of sTNFRII significantly attenuated the secretion of NO and PGE₂ in a dose-dependent manner, whereas IL6 levels were unchanged. Mean IC₅₀ values for NO and PGE₂ were found to be 35.1 and 20.5 nmol/L, respectively. CONCLUSION: Nanomolar concentrations of sTNFRII were able to significantly attenuate the effects of TNF-α on primary human IVD cells in vitro. These results suggest this sTNFR to be a potent TNF antagonist with potential to attenuate inflammation in IVD pathology.

Chemoprevention agents are an emerging new scientific area that holds out the promise of delaying or avoiding a number of common cancers. These new agents face significant scientific, regulatory, and economic barriers, however, which have limited investment in their research and development (R&D). These barriers include above-average clinical trial scales, lengthy time frames between discovery and Food and Drug Administration approval, liability risks (because they are given to healthy individuals), and a growing funding gap for early-stage candidates. The longer time frames and risks associated with chemoprevention also cause exclusivity time on core patents to be limited or subject to significant uncertainties. We conclude that chemoprevention uniquely challenges the structure of incentives embodied in the economic, regulatory, and patent policies for the biopharmaceutical industry. Many of these policy issues are illustrated by the recently Food and Drug Administration-approved preventive agents Gardasil and raloxifene. Our recommendations to increase R&D investment in chemoprevention agents include (a) increased data exclusivity times on new biological and chemical drugs to compensate for longer gestation periods and increasing R&D costs; chemoprevention is at the far end of the distribution in this regard; (b) policies such as early-stage research grants and clinical development tax credits targeted specifically to chemoprevention agents (these are policies that have been very successful in increasing R&D investment for orphan drugs); and (c) a no-fault liability insurance program like that currently in place for children's vaccines.

China has undergone dramatic economic and social reforms during last 30 years, leading to a notably higher level of living standards and health care access for Chinese citizens. However, China's cataract surgical rate of 780 cases/y per million population trails Asian neighbors with lower income levels such as India and Vietnam. Eye care providers and patients encounter many barriers in gaining access to one another.Hands-on training programs conducted by international nongovernmental organizations and the government have helped to increase the number of qualified cataract surgeons in rural area, but establishing a residency training system that produces ophthalmologists capable of performing independent surgery is the only sustainable way to meet the increasing demand for surgery from an aging population. The New Rural Cooperative Medical System has successfully reduced the financial burden of cataract surgery for the rural population; however, reimbursement for outpatient treatment of leading eye diseases is needed.Community outreach screening combined with education is essential in rural areas' increased demand for surgery. Methods to optimize the yield from such screening must still be devised and proven, however. Improvements in the hospital administration and management structure are also needed to improve the efficiency of China's rural hospitals in delivering high-quality, low-cost cataract surgical services.

STUDY DESIGN: Concurrent validity between postural indices obtained from digital photographs (two-dimensional [2D]), surface topography imaging (three-dimensional [3D]), and radiographs. OBJECTIVE: To assess the validity of a quantitative clinical postural assessment tool of the trunk based on photographs (2D) as compared to a surface topography system (3D) as well as indices calculated from radiographs. SUMMARY OF BACKGROUND DATA: To monitor progression of scoliosis or change in posture over time in young persons with idiopathic scoliosis (IS), noninvasive and nonionizing methods are recommended. In a clinical setting, posture can be quite easily assessed by calculating key postural indices from photographs. METHODS: Quantitative postural indices of 70 subjects aged 10 to 20 years old with IS (Cobb angle, 15 degrees -60 degrees) were measured from photographs and from 3D trunk surface images taken in the standing position. Shoulder, scapula, trunk list, pelvis, scoliosis, and waist angles indices were calculated with specially designed software. Frontal and sagittal Cobb angles and trunk list were also calculated on radiographs. The Pearson correlation coefficients (r) was used to estimate concurrent validity of the 2D clinical postural tool of the trunk with indices extracted from the 3D system and with those obtained from radiographs. RESULTS: The correlation between 2D and 3D indices was good to excellent for shoulder, pelvis, trunk list, and thoracic scoliosis (0.81>r<0.97; P<0.01) but fair to moderate for thoracic kyphosis, lumbar lordosis, and thoracolumbar or lumbar scoliosis (0.30>r<0.56; P<0.05). The correlation between 2D and radiograph spinal indices was fair to good (-0.33 to -0.80 with Cobb angles and 0.76 for trunk list; P<0.05). CONCLUSION: This tool will facilitate clinical practice by monitoring trunk posture among persons with IS. Further, it may contribute to a reduction in the use of radiographs to monitor scoliosis progression.

Study Design. Reliability study. Objectives. To assess between-acquisition reliability of new multilevel trunk cross sections measurements, in order to define what is a real change when comparing 2 trunk surface acquisitions of a same patient, before and after surgery or throughout the clinical monitoring. Summary of Background Data. Several cross-sectional surface measurements have been proposed in the literature for noninvasive assessment of trunk deformity in patients with adolescent idiopathic scoliosis (AIS). However, only the maximum values along the trunk are evaluated and used for monitoring progression and assessing treatment outcome. Methods. Back surface rotation (BSR), trunk rotation (TR), and coronal and sagittal trunk deviation are computed on 300 cross sections of the trunk. Each set of 300 measures is represented as a single functional data, using a set of basis functions. To evaluate between-acquisition variability at all trunk levels, a test-retest reliability study is conducted on 35 patients with AIS. A functional correlation analysis is also carried out to evaluate any redundancy between the measurements. Results. Each set of 300 measures was successfully described using only 10 basis functions. The test-retest reliability of the functional measurements is good to very good all over the trunk, except above the shoulders level. The typical errors of measurement are between 1.20° and 2.2° for the rotational measures and between 2 and 6 mm for deviation measures. There is a very strong correlation between BSR and TR all over the trunk, a moderate correlation between coronal trunk deviation and both BSR and TR, and no correlation between sagittal trunk deviation and any other measurement. Conclusion. This novel representation of trunk surface measurements allows for a global assessment of trunk surface deformity. Multilevel trunk measurements provide a broader perspective of the trunk deformity and allow a reliable multilevel monitoring during clinical follow-up of patients with AIS and a reliable assessment of the esthetic outcome after surgery.

La incidencia de la tosferina ha mostrado un incremento en los últimos años; afectando predominantemente a los niños menores de 1 año, adolescentes y adultos. En el 2005 el Comité Asesor de Prácticas en Inmunización (ACIP) recomendó administrar una dosis de refuerzo de la vacuna acelular antipertussis a los adolescentes. Esta estrategia ha sido adoptada por distintos países. Sin embargo hasta el momento no existe una revisión sistemática que evalúe la efectividad de esta medida de prevención primaria. Métodos: Revisión sistemática de la literatura de artículos acerca de la efectividad de la vacuna acelular antipertussis como dosis de refuerzo en adolescentes. Resultados: La búsqueda inicial arrojó un total de 121 resultados, de los cuales solo 4 cumplieron los criterios de selección. Se evaluó en éstos, la inmunogenicidad generada contra tétanos y difteria por la vacuna Tdap vs Td con resultados significativos y similares. Además se documentó la respuesta inmunológica protectora generada por la Tdap contra tosferina. En cuanto a la reactogenicidad, en general fue baja. Discusión: La vacuna Tdap genera inmunogenicidad similar a la Td contra tétanos y difteria. Además proporciona adecuada protección contra la tosferina como dosis de refuerzo en los adolescentes. Conclusión: La evidencia disponible sugiere que se puede recomendar la vacuna Tdap como dosis de refuerzo en adolescentes entre los 10 y los 18 años de edad por su baja reactogenicidad y adecuada inmunogenicidad contra tétanos, difteria y B. Pertussis.

Este artículo trata de mostrar de qué manera la obra de Hannah Arendt se ha convertido en un espacio teórico obligado e ineludible en el ámbito de la teoría y la filosofía política. Intenta revisar y volver a poner en consideración conceptos arendtianos, como los de libertad, política, philía, y presentarlos como una alternativa frente al derrotero apocalíptico de la historia, que se nos presenta como inevitable. Arendt fue crítica incansable del lamentable estado de la ciencia política contemporánea, por no haber sido capaz de distinguir entre conceptos como poder, autoridad o fuerza, conceptos que se han entendido como sinónimos que hacen referencia, de manera equivocada, a las relaciones de mando-obediencia. Arendt les otorga su sello propio y con ello intenta evitar la confusión que se ha generado en torno a ellos. De esta manera, define su propio matiz sobre lo político, oponiéndose radicalmente a la concepción canónica de la política como “espacio de aparición” que emana allí donde un grupo plural de seres libres e iguales comparten palabras y acciones.-----This article intends to show how Hannah Arendt’s work has become a compulsory and unavoidable theoretical forum in the realm of the political theory and philosophy. It intends to review and restate Arendtian concepts such as freedom, politics and philia, and present them as an alternative to the apocalyptic course of history that faces us as unavoidable. Arendt was a tireless judge of the pitiful state of contemporary political science because it could not differentiate concepts such as power, authority or strength, which have been understood as synonyms that wrongfully refer to a command-obedience relationship. Arendt marks them with her own seal trying to avoid the confusion that has been created around them. In this way, she defines politics in her very own way, radically opposing the canonical notion of politics as a “world of appearances” that arises where a plural group of free equal human beings shares words and actions.
