El artículo trata de establecer la ruta del grabado mexicano en los años 80 y 90 del siglo XX debido a la búsqueda y experimentación de lenguajes artísticos. En ese sentido, se exploran las ...relaciones y los vínculos del grabado con otras disciplinas visuales como la litografía, la serigrafía así como los temas en común que estas vertientes gráficas han abordado a lo largo del siglo XX. De igual manera, conforme se fue avanzando en la innovación de técnicas y el uso de nuevos materiales se abrió para los creadores pictóricos en particular y artistas plásticos en general, un nuevo horizonte de posibilidades creativas. El aspecto de la innovación pareció un camino natural para los artistas que al verse rodeados de máquinas, procesos y tecnologías poco estudiadas en el arte podían ser usadas para proponer imágenes distintas y originales.
We investigated if imaging and pathology features could help to identify a high axillary tumor burden (ATB) in breast cancer patients, in order to individualize decisions on axillary lymph node (ALN) ...dissection (ALND).
We retrospectively analyzed patients primarily treated with surgery in our unit between 2011 and 2014. We divided the patients in two groups: low ATB (LATB) if ≤ 2 ALN were infiltrated and high ATB (HATB) if > 2 ALN were infiltrated.
Data of 105 patients was included in the study. Axillary ultrasound (AUS) features associated with HATB were any sign of ALN infiltration (76 vs 24%, P = 0.027) and > 2 suspicious ALNs (73% vs 27%, P = 0.018); however, when AUS revealed ≤ 2 suspicious ALNs, 39% of these patients had HATB. Any sign of ALN infiltration on magnetic resonance imaging was associated with HATB (48% vs 52%, P = 0.031). Positive preoperative ALN cytology or biopsy was associated with HATB (53% vs 47%, P = 0.008), while p53 positivity (80% vs 20%) and high histological grade (68% vs. 32%) correlated with LATB (P = 0.05 and P = 0.02, respectively). In multivariate analysis, only positive preoperative ALN cytology or biopsy was associated with HATB (P = 0.038).
AUS was useful for detecting HATB but was not as effective in patients with LATB. Proving axillary infiltration with AUS-directed cytology or biopsy is the most effective method to predict HATB.
Background
The aim of our study was to establish which clinical, radiologic and pathologic factors could predict the risk of under- and overestimation of the breast ductal carcinoma in situ (DCIS) ...size when preoperatively measuring the maximum mammographic extent of microcalcifications (MEM).
Methods
We made a retrospective review of patients with a DCIS treated in our Breast Unit between May 2005 and May 2012. Clinical, pathologic and radiologic data were evaluated as possible predictive factors for over- or underestimation of DCIS size when measuring MEM.
Results
We obtained precise measurements of MEM in 82 patients (84 DCIS lesions). Maximum MEM measurement correctly estimated maximum pathology size in 57 lesions (68.7 %). Patients with a correctly estimated DCIS, with an underestimated DCIS and with an overestimated DCIS significantly differed in DCIS ER expression (
p
= 0.022) and in maximum MEM measurement (
p
= 0.000). Constructing two ROC curves, we found that a maximum MEM measurement ≥25 mm and ER expression ≥90 % were both discrimination points for overestimation and ER ≤ 45 % was a discrimination point for underestimation. Using these cutoff points, we defined four groups of patients with different risks of over- and underestimation.
Conclusions
Risk of over- or underestimation of DCIS size through MEM measurement depends on DCIS ER expression and MEM itself. Identifying which patients are at a significant risk of over- or underestimation could help the breast surgeon when discussing the surgical options with the patient.
Narración de la gestación y desarrollo del mural colectivo en torno a la historia de la computación en México. Dicho mural fue realizado en 1988 por estudiantes de la entonces Escuela Nacional de ...Artes Plásticas en una superficie de 170 m2 dentro de las instalaciones de la actual Dirección General de Cómputo y de Tecnologías de la Información y Comunicación (dgtic) de la Universidad Nacional Autónoma de México. En él se representan elementos trascendentales en la historia del hombre y de la ciencia. La pintura se divide de manera general en cuatro grandes ejes: el encuentro de dos culturas; la aparición de las primeras tecnologías en el mundo; el desarrollo de la computación y la presencia de las máquinas en la vida del ser humano.
Background: Workflow and preparation for holding multidisciplinary cancer case reviews (i.e., Tumor Boards) is time-consuming and cumbersome. Use of a software platform might improve this process. ...This pilot study assessed the impact of a new software platform on tumor board preparation workflow and user satisfaction compared to current methods. Materials and Methods: Using current methods and the NAVIFY Tumor Board Solution, this study assessed the number of tasks and time to prepare tumor board cases. Participants completed online surveys assessing ease of use and satisfaction with current and new platforms. Results: A total of 41 sessions included two surgeons, two oncologists, two pathologists, and two radiologists preparing tumor board cases with 734 tasks were recorded. Overall, there was no difference in the number of tasks using either preparation method (341 current, 393 NAVIFY Tumor Board solution). There was a significant difference in overall preparation time as a function of specialty (F = 71.74, P < 0.0001), with oncologists, radiologists, and surgeons having reduced times with NAVIFY Tumor Board solution compared to the current platform and pathologists having equivalent times. There was a significant difference (F = 38.98, P < 0.0001) for times as a function of task category. Review of clinical course data and other preparation tasks decreased significantly, but pathology and radiology review did not differ significantly. The new platform received higher ratings than the current methods on all survey questions regarding the ease of use and satisfaction. Conclusions: The study supported the hypothesis that the new software platform can improve Tumor Board preparation. Further study is needed to assess the impact of this platform in different hospitals, different data storage systems, with different observers, and different types of Tumor board cases as well as its impact on the quality of the tumor board discussion.
: Background and objectives: Patients with follicular lymphoma (FL) in advanced stages are currently deemed incurable with standard treatments. However, FL is considered to be eradicable in the ...small group of patients presenting with localized disease. The objective of this study was to analyze the clinical features and the outcome of a series of patients with FL in early stages with a long follow‐up.Patients and methods: A total of 48 patients (25m/23f; median age: 50 yr) diagnosed consecutively with FL in Ann Arbor stage I (25 cases) or II (23) at a single institution with a median follow‐up of 9.5 yr were included in the study. Main biological and clinical characteristics at diagnosis, including Follicular Lymphoma International Prognostic Index (FLIPI) were analyzed; treatment and response were assessed and analyzed for prognosis.Results: The histologic subtypes were: FL type I, 20 cases (42%); type II, 24 (50%); type III, three (6%); and unclassifiable, one (2%). Distribution according to FLIPI was: low risk (36 cases) and intermediate risk (five cases). Treatment mainly consisted of combination chemotherapy (CHOP in 34 cases) plus involved‐field radiotherapy in 26 cases. Forty patients (89%) achieved a complete response (CR), three (7%) a partial response, and two (4%) were non‐responders; the remaining three patients did not receive therapy. No initial variable predicted CR achievement. About 57% of the patients in CR eventually relapsed with a relapse risk of 46% at 10 yr. Intermediate‐risk FLIPI predicted failure‐free survival. Histologic transformation was observed in six patients with a 10‐yr risk of transformation of 13%. Twelve patients died during follow‐up, in two cases as a result of unrelated causes. Overall survival (OS) at 10 yr was 79%. The FLIPI was the sole variable predicting OS.Conclusions: Although the majority of patients with localized FL achieve CR, the risk of relapse is high. The FLIPI is of prognostic value in these patients.
La hipótesis de esta investigación, ha partido de la idea de que la muerte se presenta de manera universal, siendo el único destino común de todo ser viviente. Si bien la muerte ha sido estudiada ...desde distintos enfoques, su inclusión implícita o explícita a través de la imagen en impresos, grabados y estampas es el motivo principal de este trabajo. La muerte por lo tanto representa una respuesta a los imaginarios simbólicos pudiendo ser estudiada en el marco de las Bellas Artes.
El objetivo general se ha construido a partir de cuatro secciones que corresponden a tiempos históricos y percepciones distintas de a muerte y que se encuentran al mismo interrelacionadas: la prehispánica, la colonial, la surgida de la independencia, la moderna y contemporánea. Estos temas se abordan mediante apartados o sub/capítulos que son acompañados de imágenes gráficas que tienen la intención de ilustrar y de reforzar el texto indicándose al final de la investigación su procedencia respectiva.
