Trayectoria en las obras de Jorge Pinzón

Pinzón Malagón, Jorge Humberto

Este manuscrito sintetiza la trayectoria compositiva de Jorge Humberto Pinzón Malagón, cuyo proceso formativo se inicia en la Escuela Superior de Música de Tunja y se consolida en el Conservatorio Chaikovsky de Moscú, contexto que moldea su método y lenguaje creativos. La producción se organiza en dos etapas: (i) los c...

Descubrimiento incidental de gran secuestro pulmonar en un paciente pediátrico

Vargas-Echeverría, Carlos · Echeverría-Consuegra, Rafael

Neoadjuvant chemotherapy in cervical cancer: a narrative review

Nathalia Mora-Soto · David Viveros-Carreño · Carolina Morante-Caicedo · William Piñeros · y 2 más

Cervical cancer continues to be a major global health challenge, particularly in resource-limited settings. Neoadjuvant chemotherapy has been proposed as a strategy to improve oncologic and reproductive outcomes in selected patients, offering an alternative or complement to standard treatments. This narrative review su...

Biological Information as Conformally Invariant Topological Data: A Cyclic Cosmology Solution to Initial Condition Fine-Tuning in Prebiotic Chemistry

Javier, Burgos-Salcedo

The origin of life's rapid emergence (~109 years) and universal biochemical features (homochirality, conserved metabolic pathways) present a fundamental puzzle: random chemical search in configuration space predicts timescales exceeding 10123 years, rendering biogenesis impossible within cosmic history. We present a co...

Terapias dirigidas en amiloidosis cardíaca por transtiretina: una revisión del contexto clínico contemporáneo

Costabel, Juan P. · Suárez, Lucas L. · Escalante-Seyffert, M. Cecilia · de León, Juan D. López-Ponce · y 2 más

Transthyretin cardiac amyloidosis is a recently recognized disease, still significantly underdiagnosed. It is characterized by infiltration of amyloid proteins resulting from the destabilization of the transthyretin protein produced in the liver. There are two predominant presentations, the hereditary form and the wild...

Evaluating Topical Antifibrinolytics in Cardiac Surgery: A Systematic Review, Meta-Analysis, and Trial Sequential Analysis

Juan Sebastian Montoya-Beltran · Laura Ramirez-Herrera · Jorge Leandro Pinilla · Andres Herazo-Cubillos · y 2 más

Lysine analog antifibrinolytics (LAAF) like tranexamic acid (TXA) and aminocaproic acid (EACA) reduce intraoperative blood loss, especially in cardiac surgery where bleeding risks are high. These LAAFs inhibit fibrinolysis and have been proven to decrease bleeding and transfusion volume. In cardiac surgery, frequent tr...

Extreme cardiac MRI analysis under respiratory motion: Results of the CMRxMotion challenge

Wang, Kang · Qin, Chen · Shi, Zhang · Wang, Haoran · y 45 más

Deep learning models have achieved state-of-the-art performance in automated Cardiac Magnetic Resonance (CMR) analysis. However, the efficacy of these models is highly dependent on the availability of high-quality, artifact-free images. In clinical practice, CMR acquisitions are frequently degraded by respiratory motio...

Experimental evidence of ciliate dispersal and successional patterns via endozoochory in temporary aquatic systems

Cochak, Crislaine · Green, Andy · Sanchez, Marta · Pineda, Alfonso · y 2 más

Temporary aquatic ecosystems in Mediterranean regions rely on passive dispersal to maintain connectivity among isolated habitats. In Doñana National Park, Spain, aquatic birds enhance this connectivity by dispersing microbial propagules via endozoochory. We tested whether ciliate dispersal through bird feces facilitate...

Health system barriers to early detection and timely treatment of breast cancer: A scoping review

Jorge A. Ramos-Castaneda · Deyanira A. Joven-Gonzalez · Olga Y. Cardozo-Vasquez · Viviana Perez-Becerra

In 2022, breast cancer (BC) had a global mortality rate of 12.7 per 100,000 and 13.2 per 100,000 in Latin America. In Colombia, BC ranked among the leading cancers in terms of incidence and mortality. Delayed diagnosis and treatment worsen prognosis and increase both morbidity and mortality. This review aimed to descri...
