Bracing Adult Scoliosis: From Immobilization to Correction of Adult Scoliosis

Unlike adolescent idiopathic scoliosis, bracing was used in adults less and was used more as a way of reducing pain. There is little publication of adult scoliosis series in the literature. The use of very high-rigidity and high-precision CAD/CAM technologies currently makes it possible to create corrective braces for the adult. The digital CAD/CAM cast in three blocks allows for precise correction at the pelvic, lumbar, and thoracic levels. This chapter presents the results of a series of 62 consecutive adult scoliotic patients treated with a corrective asymmetric detorsion brace of very high rigidity made in 2014–2016. Tolerance and angular correction results will be compared to those of 158 patients treated with the former bivalve polyethylene overlapping immobilization brace mainly used for lumbar scoliosis. The new Lyon adult ARTbrace is a detorsion brace adapted to all the curvatures which controls the sagittal plane. Despite a resistance four times greater than that of polyethylene of the same thickness, the tolerance of the Europlex’O is excellent as it is a “shock absorber,” and the anterior opening facilitates the use for very old people. Consequently, the aim of this chapter is to consider if it is possible to envisage for some patients an alternative to surgery, thanks to the new technologies of bracing

Young planets (<1 Gyr) offer an opportunity to probe the critical early stages of this evolution, where planets evolve the fastest. However, most of the known young planets orbit prohibitively faint stars. We present the discovery of two planets transiting HD 63433 (TOI 1726, TIC 130181866), a young Sun-like (M∗=0.99±0.03) star. Through kinematics, lithium abundance, and rotation, we confirm that HD 63433 is a member of the Ursa Major moving group (τ=414±23 Myr). Based on the TESS light curve and updated stellar parameters, we estimate the planet radii are 2.15±0.10R⊕ and 2.67±0.12R⊕, the orbital periods are 7.11 and 20.55 days, and the orbital eccentricities are lower than about 0.2. Using HARPS-N velocities, we measure the Rossiter-McLaughlin signal of the inner planet, demonstrating that the orbit is prograde. Since the host star is bright (V=6.9), both planets are amenable to transmission spectroscopy, radial velocity measurements of their masses, and more precise determination of the stellar obliquity. This system is therefore poised to play an important role in our understanding of planetary system evolution in the first billion years after formation.PostprintPeer reviewe

Dry Eye in Systemic Sclerosis Patients: Novel Methods to Monitor Disease Activity

Background: In systemic sclerosis (SSc) patients, dry eye syndrome (DES) is the most frequent ocular feature. The aim of this study was to investigate ocular DES-related SSc patients and to establish any correlation with the severity of the disease. Methods: Retrospectively, data from 60 patients with SSc underwent ophthalmic examination, where non-invasive film tear break-up time (NIF-TBUT), tear film lipid layer thickness (LLT), anesthetic-free Schirmer test I, tear osmolarity measurement (TearLab System), and modified Rodnan skin score (mRSS) data were collected. The visual analog scale (VAS) and Symptom Assessment in Dry Eye (SANDE) methods were utilized. The results were correlated with mRSS and the duration of SSc. Results: Severe DES occurred in 84% of cases, and was more severe in women. The eyelids were involved in 86.6%, secondary to meibomian gland disease (MGD). A direct correlation was found between the tear osmolarity (mean 328.51 &plusmn; 23.8 SD) and skin score (mRSS) (r = 0.79; p &lt; 0.01). Significantly reduced NIF-TBUT, LLT, and Schirmer test I values were observed in the case of severe skin involvement. Conclusions: SSc patients show lipid tear dysfunction related to the severity and duration of the disease due to inflammation and the subsequent atrophy of the meibomian glands

Elementos escenciales para programación: Algoritmos y Estructuras de Datos

Este libro está principalmente dirigido a estudiantes universitarios que se inician en las carreras de Ingeniería. Son los que deben interiorizarse en el manejo de ciertos recursos propios de la disciplina sin orientarse a ningún lenguaje en particular. La finalidad de este enfoque es ampliarles la perspectiva para que en su vida profesional no sólo puedan implementar programas en los lenguajes clásicos de programación sino que también sean capaces de manejar las nuevas herramientas de software que, en muchos casos, permiten optimizar su rendimiento mediante el desarrollo de macroinstrucciones especiales.Es así que en la elaboración del libro hemos decidido tratar los conceptos de manera no muy extensa y, en la forma más sencilla posible. No sólo para que se constituya en un soporte de los contenidos a desarrollar por los docentes sino para que les permita a los estudiantes reflexionar sobre la forma de llegar a un algoritmo como solución a un problema.A los fines didácticos, representamos los algoritmos en algunos casos con pseudocódigo y en otros, con diagrama de flujo o con ambos tipos de representacionesFil: Gagliano, María Gracia.
