Durante la cursada no presencial del primer cuatrimestre de 2020, las instancias de planificación y desarrollo de los trabajos que integran el taller se vieron modificadas. En esta ponencia, presentamos una revisión de las prácticas llevadas a cabo en la construcción de un espacio aúlico mediatizado. Es decir, ante las medidas de aislamiento, nuestro espacio de encuentro se extendió en redes (tales como Instagram, Facebook y la plataforma MIEL-UNLAM) no solo para la comunicación entre docentes y estudiantes sino como espacios para desarrollar el concepto, la imagen y la campaña de la marca persona del comunicador. Es necesario considerar que cada estudiante debió reconocer un perfil como profesional de la comunicación y adaptar su mensaje en distintas piezas gráficas para redes sociales. Para ello, sistematizamos encuestas a los estudiantes y presentamos fragmentos de interacciones en distintos espacios donde se promueve el intercambio creativo.

However, evidence guiding the duration of prophylactic treatment remains limited. OBJECTIVE To assess the effect of a 5-day regimen of postoperative, prophylactic, intravenous antibiotics compared with a 1-day regimen on the rate of surgical site infections within 1 year after surgery. DESIGN, SETTING, AND PARTICIPANTS This randomized clinical superiority trial was performed at 48 clinical sites in 12 countries from January 1, 2013, to October 29, 2019. The trial included patients with a primary bone tumor or a soft tissue sarcoma that had invaded the femur or tibia or oligometastatic bone disease of the femur or tibia with expected survival of at least 1 year who required surgical management by excision and endoprosthetic reconstruction. A total of 611 patients were enrolled, and 7 were excluded for ineligibility. INTERVENTIONS A 1-or 5-day regimen of postoperative prophylactic intravenous cephalosporin (cefazolin or cefuroxime) that began within 8 hours after skin closure and was administered every 8 hours thereafter. Those randomized to the 1-day regimen received identical saline doses every 8 hours for the remaining 4 days; patients, care providers, and outcomes assessors were blinded to treatment regimen. MAIN OUTCOMES AND MEASURES The primary outcome in this superiority trial was a surgical site infection (superficial incisional, deep incisional, or organ space) classified according to the criteria established by the Centers for Disease Control and Prevention within 1 year after surgery. Secondary outcomes included antibiotic-related complications, unplanned additional operations, oncologic and functional outcomes, and mortality. RESULTS Of the 604 patients included in the final analysis (mean [SD] age, 41.2 [21.9] years; 361 [59.8%] male; 114 [18.9%] Asian, 43 [7.1%] Black, 34 [5.6%] Hispanic, 15 [2.5%] Indigenous, 384 [63.8%] White, and 12 [2.0%] other), 293 were randomized to a 5-day regimen and 311 to a 1-day regimen. A surgical site infection occurred in 44 patients (15.0%) allocated to the 5-day regimen and in 52 patients (16.7%) allocated to the 1-day regimen (hazard ratio, 0.93; 95% CI, 0.62-1.40; P = .73). Antibiotic-related complications occurred in 15 patients (5.1%) in the 5-day regimen and in 5 patients (1.6%) allocated to the 1-day regimen (hazard ratio, 3.24; 95% CI, 1.17-8.98; P = .02). Other secondary outcomes did not differ significantly between treatment groups. CONCLUSIONS AND RELEVANCE This randomized clinical trial did not confirm the superiority of a 5-day regimen of postoperative intravenous antibiotics over a 1-day regimen in preventing surgical site infections after surgery for lower extremity bone tumors that required an endoprosthesis. The 5-day regimen group had significantly more antibiotic-related complications.

Desde el espacio reducido del barco, un satelite que permite la observacion sin contacto, el navegante describe los recortes costeros. El barco es un refugio. Es proteccion y resistencia. Quien camina, en cambio, se expone y sus representaciones permiten observar ciertos desplazamientos en la subjetividad del viajero.

The processbased NZ-DNDC model was modified to better simulate soil pH changes and ammonia (NH 3) emissions following urine application using data collected from a New Zealand field trial. After modification, simulated 30-day NH 3 emissions decreased from 506 to 117 kg N ha-1 compared to measured emissions of 78 ± 3 kg N ha-1 (mean ± standard error) and the Nash-Sutcliffe Efficiency (NSE) for daily NH 3 emissions increased from-7.11 to ?0.97 for the parameterisation dataset. However, modified model correctly estimated the cumulative emissions for the first 7 days. Using the same parameterisation on an independent dataset from a nearby site gave cumulative 18-day NH 3 emissions of 84 kg N ha-1 compared to the measured 48 ± 2 kg N ha-1 (mean ± standard error). However, the NSE for daily NH 3 emissions was-0.71, indicating site specific parameterisation might be needed. The sensitivity of NH 3 emissions to ±5 and ±10% errors in 4 model parameters was tested. The sensitivities ranged from-0.36 to ?0.71. The highest sensitivity was to the rate of NH 3 transfer from the soil solution to the atmosphere and the lowest sensitivity was to the rate of urea hydrolysis.

Bright noted that sunlight or light from a candle was able to shine through the head of a patient who suffered from hydrocephalus, a disorder characterized by excess cerebrospinal fluid in and around the brain. The ability of light to transilluminate tissues was later noted by Curling in 1843 in conjunction with problems of the scrotum, and by Cutler in 1929 in relation to breast lesions. The year 1977 represented another pivotal point for the field of optical biomedical diagnostics. It was then that Frans Jobsis demonstrated the deep transillumination of mammalian tissues using near-infrared (NIR) light, including the chest of a dog and an adult human head from temple to temple. Furthermore, by combining the penetrating properties of NIR light with spectroscopy, he demonstrated the diagnostic value of NIR light for the assessment of hemoglobin oxygen saturation and the cytochrome a-a3 redox state. Given the cellular metabolic information afforded by NIR spectroscopy, coupled with its deeply penetrating and noninvasive properties and the intrinsic low cost of optical technology, it is apparent that this new biomedical tool holds great promise for diagnosing a variety of pathologies. One fundamental limitation of the use of NIRS for diagnostic purposes is the problem of localizing the origin of the signals. One can easily demonstrate the extent of this limitation with simple experiments, which most of us have done at one time or another. For example, in a darkened room, take a bright penlight or a red laser pointer and place it under your thumb. As you activate the light source, you will readily observe your fingernail and the surrounding tissue glowing with deep red light, confirming the ability of red/NIR radiation to transilluminate thick mammalian tissue. A typical pattern of light emerging from the finger is shown in Fig. 6.1. What is notably missing from this light pattern is imaging information about the internal structure of the thumb. There is no evidence, for example, that the bone in the finger is casting a shadow. To the unaided eye, the inside of the thumb appears to be filled with a homogeneous medium.

In 2014, an interdisciplinary project started with the participation of several professionals of medical and social sciences. This case study provides an account of the research process from the social science perspective. Specifically, it is focused on the methodological approach that we used for building our data collection technique. Because in the broader study we had to establish the credibility and reliability criteria of our intervention, we designed an in-depth interview following these four evaluative criteria: credibility, capacity for change and transfer, operational safety, and capability of the method to be corroborated and confirmed. This method of autoevaluation of qualitative research can be applied to any topic abiding by social or naturalistic scientists.

PI3K/Akt pathway is deregulated in almost 50% of breast carcinomas, and is associated to therapy resistance. Currently, there are increasing clinical trials that combine endocrine treatments with PI3K/Akt inhibitors to delay tumor resistance and to avoid tumor progression. However, these inhibitors do not distinguish between the isoform specific function of Akt1, Akt2 and Akt3. Several evidences in different models of cancer show that Akt1 and Akt2 are expressed in different stages of cancer progression, with Akt1 involved in tumor proliferation during the first steps of the carcinogenic process, and Akt2 involved in the invasive phenotype. The aim of this work was to study Akt1 and Akt2 isoforms, focusing on their particular role in cell migration and...
