La influencia del consumo de pornografía en la construcción de la sexualidad masculina de jóvenes chilenos.

Este trabajo está orientado a conocer la influencia que ejerce la pornografía en la construcción de la sexualidad de hombres jóvenes consumidores de la ciudad de Temuco, Chile. De acuerdo con la literatura la pornografía es vista de forma mayoritaria por jóvenes varones que van desde los 12 años hasta su adultez. Esta situación influye en la socialización de los varones y en su concepción de la sexualidad que resulta ser problemática como consecuencia de este consumo. Para esto se realizó una investigación de carácter cualitativo en la cual se aplicaron diez entrevistas semiestructuradas a jóvenes consumidores de 21 a 26 años y a dos expertos (en educación y en sexualidad). Los resultados apuntan a la existencia una fuerte influencia de la pornografía en la sexualidad de los jóvenes. No limitada solo a la sexualidad, sino que además a la concepción propia de la masculinidad y su rol en las relaciones afectivos-sexuales. Finalmente, los resultados evidencian que los jóvenes reflexionan sobre los elementos negativos que han debido afrontar dadas las sustanciales diferencias que tiene la ficción con la realidad en el consumo de pornografía

Integration of space-holder technique and spark plasma sintering. An innovative approach for crafting radially graded porosity implants

Bone resorption and possible fracture of host tissue are some consequences resulting from the mismatch between the Young's Modulus of the constituent materials of implants and bone that compromises the reliability of implants for replacing damaged bone tissue. The use of functional graded porous materials presents an interesting approach that could help decrease the Young's modulus while simultaneously mimicking highly hierarchical porosity of the bone structure. However, these structures are more difficult to fabricate than those with homogenous porosity. The design and distribution of this porosity in the implant must ensure the biomechanical and biofunctional balance of the bone tissue it is intended to replace. In this study, Ti radially graded structures were successfully fabricated using Spark Plasma Sintering combined with Space Holder Technique. The effects of temperature on porosity and mechanical properties were thoroughly examined. The results indicated that this processing route allows to achieve good control of porosity, close to the amount of added spacer. Yield stress of 181 MPa and an elastic modulus of 56 GPa were obtained for samples sintered at 800 °C for 5 min under a pressure of 6.3 MPa. These mechanical properties make the structure a viable candidate for replacing human long bones

Different outcomes for transplant-eligible newly diagnosed multiple myeloma patients in Latin America according to the public versus private management: a GELAMM study

The aim of this study was to describe clinical and survival characteristics of transplant-eligible multiple myeloma (MM) patients in Latin America (LA), with a special focus on differences between public and private healthcare facilities. We included 1293 patients diagnosed between 2010 and 2018. A great disparity in outcomes and survival between both groups was observed. Late diagnosis and low access to adequate frontline therapy and ASCT in public institutions probably explain these differences. Patients treated with novel drug induction protocols, followed by autologous stem cell transplantation (ASCT) and maintenance, have similar overall survival compared to that published internationally
