Early diagnosis and risk stratification of aortic stenosis using artificial intelligence applied to echocardiography: scoping review

Gabriel Eduardo Malagón Tarqui · Juanita Valencia García · Erwin Hernando Hernández Rincón

Aortic stenosis (AS) is the most common acquired valvular heart disease worldwide, accounting for 43% of valvular diseases. It is estimated that 40-50% of patients with severe symptomatic AS do not receive intervention, resulting in a mortality rate of over 90%. Transthoracic echocardiography remains the gold standard...

From early adversity to juvenile delinquency: The mediating role of marijuana use, PTSD symptoms and inhibitory control in adolescent males

Edgar Gerardo Alejo Castillo · Jorge Mauricio Cuartas Arias

Early adverse experiences (EAE) have been linked to posttraumatic stress symptoms (PTSS), externalising behaviour problems (EBP), and juvenile delinquency (JD). This study examined whether PTSS, inhibitory control deficit (ICD), and problematic marijuana use (PMU) operate as parallel mediators between EAE and these out...

Machine learning models for early detection of urinary tract infections in kidney transplant patients

Alejandro Camargo-Salamanca · Liceth Viviana Castañeda-Silva · Carlos Puentes-Morales · Alejandro Duitama-Leal · y 7 más

Renal transplantation is the preferred treatment for end-stage chronic kidney disease but requires lifelong immunosuppression, increasing the risk of infections such as urinary tract infection (UTI). UTI in kidney transplant recipients can lead to serious complications, including acute kidney injury, reduced graft surv...

Macrolitter accumulation in tidal marsh wrack deposits in a large estuary

Garcés Ordóñez, Ostin · Canals Artigas, Miquel · Noyce, Genevieve · Rovai, André · y 2 más

Wrack refers to debris deposited along the upper intertidal zone by waves and tides. In the past, wrack consisted mainly of natural debris, but modern wrack includes anthropogenic macrolitter (AML). When AML is abundant, wracks become pollution hotspots that threaten ecosystem functioning. Here, we assess AML abundance...

FIGO / IGCS statement on the efficacy of topical treatments for high‐risk human papillomavirus in preventing CIN 3+ lesions

René Pareja · Fernando Heredia · Emmanuel Sánchez-Díaz · Mauricio A. Cuello · y 18 más

Abstract Cervical cancer is caused by persistent high‐risk human papillomavirus (HR‐HPV) infection and remains a major global health burden despite available preventive strategies. Most HR‐HPV infections and associated low‐grade squamous intraepithelial lesions (LSIL) regress spontaneously, yet increasing commercial pr...

Acute Myocardial Infarction Secondary to Idiopathic Ascending Aortic Thrombus

Nathalia Melo-González · Ana Lucía Madrid-Marín · Orlando Castaño-Cifuentes · Martín Elías Arrieta-Mendoza

Ascending aortic thrombus causing acute myocardial infarction through coronary ostial occlusion is exceptional, with only 74 cases reported globally, and may mimic acute aortic dissection on imaging.A 48-year-old man with no prior history presented with ST-elevation myocardial infarction. Coronary angiography showed ne...

Syndromic surveillance in slaughterhouses: A scoping review

Mayra A. Quiroga-Robayo · Fernanda C Dórea · Nathalia M. Correa-Valencia

Syndromic surveillance in slaughterhouses represents a valuable approach for early disease detection and large-scale animal health monitoring. Despite its increasing application, the evidence base remains fragmented, and important methodological and terminological inconsistencies persist. This scoping review seeks to p...

Las competencias motrices básicas constituyen un componente esencial del desarrollo motor infantil y representan la base para la participación en actividades físicas, deportivas y de la vida cotidiana. Su evaluación durante la edad escolar permite identificar fortalezas y dificultades motrices, favoreciendo la planific...

On Γ-embeddings and partial actions on function spaces

Luis A. Martínez-Sánchez · Héctor Pinedo · José L. Vilca-Rodríguez

This paper deals with the extension of partial actions of topological groups on topological spaces. Within this framework, we introduce a class of topological embeddings defined via the inverse semigroup of homeomorphisms between open subsets of a topological space. We describe several embeddings of this type, referred...
