Video summarization by group scoring

In this paper a new model for user-centered video summarization is presented. Involvement of more than one expert in generating the final video summary should be regarded as the main use case for this algorithm. This approach consists of three major steps. First, the video frames are scored by a group of operators. Next, these assigned scores are averaged to produce a singular value for each frame and lastly, the highest scored video frames alongside the corresponding audio and textual contents are extracted to be inserted into the summary. The effectiveness of this approach has been evaluated by comparing the video summaries generated by this system against the results from a number of automatic summarization tools that use different modalities for abstraction

Neutron imaging and tomography with MCPs

A neutron imaging detector based on neutron-sensitive microchannel plates (MCPs) was constructed and tested at beamlines of thermal and cold neutrons. The MCPs are made of a glass mixture containing B-10 and natural Gd, which makes the bulk of the MCP an efficient neutron converter. Contrary to the neutron sensitive scintillator screens normally used in neutron imaging, spatial resolution is not traded off with detection efficiency. While the best neutron imaging scintillators have a detection efficiency around a percent, a detection efficiency of around 50% for thermal neutrons and 70% for cold neutrons has been demonstrated with these MCPs earlier. Our tests show a performance similar to conventional neutron imaging detectors, apart from the orders of magnitude better sensitivity. We demonstrate a spatial resolution better than 150 um. The sensitivity of this detector allows fast tomography and neutron video recording, and will make smaller reactor sites and even portable sources suitable for neutron imaging.Comment: Submitted to the proceedings of the 19th International Workshop on Radiation Imaging Detectors (iWoRiD) 2-6 July 2017, Krakow, Polan

Abordagem Triangular e Processo Criativo

The article aims to explore the contribution of Ana Mae Barbosa's Triangular Approach (2008) to the development of creativity, as well as to demonstrate the importance of image reading with emphasis on the creative process to assist in the construction of authorial poetics. The work will reflect on sensations and metaphors as an image reading strategy based on the work of Yêdamaria (1932-2016) and the Campana brothers (1953-,1961). The theoretical framework has authors such as: Barbosa (1998, 2008), Paulo Freire (1996, 2011); Duarte Júnior (2010), and Lakoff and Jonson (2002). The work infers that the Triangular Approach significantly contributes to the creative process.El artículo tiene como objetivo explorar la contribución del Enfoque Triangular de Ana Mae Barbosa (2008) al desarrollo de la creatividad, así como demostrar la importancia de la lectura de imágenes con énfasis en el proceso creativo para ayudar en la construcción de la poética del autor.

Laparoscopic surgery in morbidly obese patients with endometrial cancer

Introduction: surgery in morbidly obese patients as a treatment for gynecologic cancer is a challenge for surgeons and anesthesiologists, since it is associated with the processes of increasing intraoperative and postoperative complications. Objective: to describe the main results gained with the use of laparoscopic surgery in patients with morbid obesity and endometrial adenocarcinoma treated at the Instituto Nacional de Oncología y Radiobiología (INOR) of Havana, Cuba, from January 2019 to March 2020. Method: a descriptive, observational, cross-sectional study was carried out in 22 patients, with body mass index more than 40 kg/m2 and diagnosis of endometrial adenocarcinoma, who underwent laparoscopic surgery. The primary data was obtained from the medical records, which were used to create a database in a Microsoft Excel spreadsheet to synthesize all the information. Results: the predominant age group was between 61 and 70 years old. Endometrial adenocarcinoma was the most frequent cancer (77.27%). The degree of differentiation was well differentiated, infiltrating less than 50 % of the myometrium. The predominant surgical staging was IA (72.72%). Transoperative bleeding was 78.9 ± 5.7 ml (range between 10 and 200 ml), mean operative time was 82 min (range 75-132 min), and hospital stay was less than 24 hours (90.90%). Surgical conversion was performed in 4.54% of cases. Conclusions: morbidly obese patients may benefit from the laparoscopic approach for the treatment and laparoscopic surgical staging of endometrial carcinoma, which decreases morbidity and hospital stay

Intensidade da intradermorreação de Montenegro e tempo de evolução da lesão como preditores de falha na resposta terapêutica da leishmaniose cutânea

A case-control study was conducted to examine the association among the Montenegro skin test (MST), age of skin lesion and therapeutic response in patients with cutaneous leishmaniasis (CL) treated at Evandro Chagas National Institute of Infectious Diseases (INI), Oswaldo Cruz Foundation (FIOCRUZ), Rio de Janeiro, Brazil. For each treatment failure (case), two controls showing skin lesion healing following treatment, paired by sex and age, were randomly selected. All patients were treated with 5 mg Sb5+/kg/day of intramuscular meglumine antimoniate (Sb5+) for 30 successive days. Patients with CL were approximately five times more likely to fail when lesions were less than two months old at the first appointment. Patients with treatment failure showed less intense MST reactions than patients progressing to clinical cure. For each 10 mm of increase in MST response, there was a 26% reduction in the chance of treatment failure. An early treatment - defined as a treatment applied for skin lesions, which starts when they are less than two months old at the first appointment -, as well as a poor cellular immune response, reflected by lower reactivity in MST, were associated with treatment failure in cutaneous leishmaniasis.Conduzimos estudo caso-controle que verificou a associação entre a intradermorreação de Montenegro (IDRM), o tempo de evolução da lesão e a resposta terapêutica em pacientes com leishmaniose cutânea (LC) atendidos no Instituto de Infectologia Evandro Chagas (INI), Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, Brasil. Para cada caso com má resposta à terapêutica foram selecionados aleatoriamente dois controles que evoluíram com cicatrização das lesões após o tratamento, pareados por sexo e idade. Todos os pacientes realizaram tratamento com antimoniato de meglumina (Sb5+) IM, na dose de 5 mg Sb5+/kg/dia, continuamente, por 30 dias. Pacientes com LC apresentaram aproximadamente cinco vezes mais chance de falhar quando as lesões apresentavam menos de dois meses de evolução no primeiro dia de atendimento. Pacientes com falha terapêutica apresentaram reações de IDRM menos intensas que pacientes que evoluíram para a cura clínica. A cada 10 milímetros de aumento na resposta à IDRM, houve uma redução de 26% na chance de ocorrência de falha. O tratamento precoce, traduzido pelo tempo de evolução da lesão menor que dois meses no primeiro dia de atendimento, e resposta de imunidade celular deficiente, traduzida por IDRM menos intensa, demonstraram contribuir para a ocorrência de falha terapêutica na leishmaniose cutânea

Validación de la utilidad de los parámetros de deformación miocárdica para excluir el rechazo agudo tras el trasplante cardiaco: un estudio multicéntrico

Multicenter study[Abstract] Introduction and objectives: Two-dimensional speckle-tracking echocardiography has emerged as a promising alternative to endomyocardial biopsy to rule out acute cellular rejection after orthotopic heart transplantation (OHT) in single center studies. In an original cohort, 15.5% and 17% of cutoff points for left ventricular global longitudinal strain (LVGLS) and free-wall right ventricular longitudinal strain, respectively, achieved 100% negative predictive value to exclude moderate or severe acute cellular rejection (ACR ≥ 2R). Our objective was to demonstrate the usefulness of speckle-tracking and validate these cutoff points in an external cohort. Methods: A prospective, multicenter study that included patients who were monitored during their first year after OHT was conducted. Echocardiographic studies analyzed by local investigators were compared with simultaneous paired endomyocardial biopsies samples. Results: A total of 501 endomyocardial biopsy-echocardiographic studies were included in 99 patients. ACR≥2R was present in 7.4% of samples. LVGLS and free-wall right ventricular longitudinal strain were significantly reduced during ACR≥2R on univariate analysis. On multivariate analysis, LVGLS was independently associated with the presence of ACR≥2R. The original cutoff points demonstrated a negative predictive value of 94.3% to exclude ACR≥2R. Conclusions: This study maintained a strong negative predictive value to exclude ACR≥2R after OHT and LVGLS was independently associated with the presence of ACR≥2R. We propose the use of speckle-tracking, especially LVGLS, as part of the noninvasive diagnosis and management of ACR.[Resumen] Introducción y objetivos. Algunos estudios indican que los parámetros de strain por speckle-tracking pueden ser una alternativa no invasiva a la biopsia endomiocárdica para excluir el rechazo celular agudo (RCA) moderado o grave (≥ 2 R) tras el trasplante cardiaco (TxC). En una cohorte inicial, unos puntos de corte del 15,5% para el strain longitudinal global del ventrículo izquierdo (SLGVI) y el 17% para el strain de pared libre del ventrículo derecho mostraron un valor predictivo negativo del 100% para excluir RCA ≥ 2 R. Nuestro objetivo es analizar la utilidad del strain y validar estos puntos de corte en una cohorte multicéntrica prospectiva externa. Métodos. Estudio multicéntrico y prospectivo que incluyó a pacientes con seguimiento el primer año tras el TC. Se compararon los resultados de biopsias electivas con ecocardiogramas realizados el mismo día. Resultados. Se incluyó a 99 pacientes y 501 pares de biopsias-ecocardiogramas. El RCA ≥ 2 R en las biopsias fue del 7,4%. El SLGVI y el strain longitudinal de pared libre del ventrículo derecho fueron menores durante los RCA ≥ 2 R en el análisis univariante. En el análisis multivariante, el SLGVI se asoció de manera independiente con el RCA ≥ 2 R. Los puntos de corte originales mostraron un valor predictivo negativo del 94,3% el RCA ≥ 2 R. Conclusiones. Este estudio mantiene un alto valor predictivo negativo para excluir RCA ≥ 2 R tras el TxC y el SLGVI se asoció de manera independiente con el RCA ≥ 2 R. El strain y, principalmente, el SLGVI pueden ser de utilidad en el diagnóstico y el tratamiento no invasivo del RCA

Impacto de la edad del donante-receptor en la supervivencia al trasplante cardiaco. Subanálisis del Registro Español de Trasplante Cardiaco

[Abstract] Introduction and objectives. The age of heart transplant recipients and donors is progressively increasing. It is likely that not all donor-recipient age combinations have the same impact on mortality. The objective of this work was to compare survival in transplant recipients according to donor-recipient age combinations. Methods. We performed a retrospective analysis of transplants performed between 1 January 1993 and 31 December 2017 in the Spanish Heart Transplant Registry. Pediatric transplants, retransplants and combined transplants were excluded (6505 transplants included). Four groups were considered: a) donor < 50 years for recipient < 65 years; b) donor < 50 years for recipient ≥ 65 years; c) donor ≥ 50 years for recipient ≥ 65 years, and d) donor ≥ 50 years for recipient < 65 years. Results. The most frequent group was young donor for young recipient (73%). There were differences in the median survival between the groups (P < .001): a) younger-younger: 12.1 years, 95%CI, 11.5-12.6; b) younger-older: 9.1 years, 95%CI, 8.0-10.5; c) older-older: 7.5 years, 95%CI, 2.8-11.0; d) older-younger: 10.5 years, 95%CI, 9.6-12.1. On multivariate analysis, independent predictors of mortality were the age of the donor and the recipient (0.008 and 0.001, respectively). The worst combinations were older-older vs younger-younger (HR, 1.57; 95%CI, 1.22-2.01; P < .001) and younger-older vs younger-younger (HR, 1.33; 95%CI, 1.12-1.58; P = .001). Conclusions. Age (of the donor and recipient) is a relevant prognostic factor in heart transplant. The donor-recipient age combination has prognostic implications that should be identified when accepting an organ for transplant.[Resumen] Introducción y objetivos. La edad de receptores y donantes cardiacos se está incrementando progresivamente. Es probable que no todas las combinaciones tengan el mismo impacto en la mortalidad. El objetivo de este trabajo es comparar la supervivencia de los pacientes trasplantados según la combinación de edades de donante y receptor. Métodos. Análisis retrospectivo del Registro Español de Trasplante Cardiaco de los trasplantes realizados entre el 1 de enero de 1993 y el 31 de diciembre de 2017. Se excluyeron los pediátricos, los retrasplantes y los trasplantes combinados (se incluyeron 6.505 trasplantes). Se consideraron 4 grupos: a) donante menor de 50 años para receptor menor de 65 años; b) donante menor de 50 años para receptor de edad ≥ 65 años; c) donante de edad ≥ 50 años para receptor de 65 o más, y d) donante de edad ≥ 50 años para receptor menor de 65. Resultados. El grupo más frecuente fue el de donante joven para receptor joven (73%). Hubo diferencias en la mediana de supervivencia entre los grupos (p < 0,001): a) joven-joven: 12,1 años (IC95%, 11,5-12,6); b) joven-mayor: 9,1 años (IC95%, 8,0-10,5); c) mayor-mayor: 7,5 años (IC95%, 2,8-11,0), y d) mayor-joven: 10,5 años (IC95%, 9,6-12,1). En el análisis multivariante, las edades del donante y del receptor resultaron predictoras independientes de la mortalidad (0,008 y 0,001 respectivamente). Las peores combinaciones fueron mayor-mayor frente a joven-joven (HR = 1,57; IC95%, 1,22-2,01; p < 0,001) y joven-mayor frente a joven-joven (HR = 1,33; IC95%, 1,12-1,58; p = 0,001). Conclusiones. La edad (del donante y del receptor) es un factor pronóstico relevante en el trasplante cardiaco. La combinación de edades de donante y receptor posee implicaciones pronósticas que se debe conocer a la hora de aceptar un órgano para trasplante
