Factors associated with intensive care professionals' ability to identify patient–ventilator asynchronies: A systematic review and meta-analysis

Andrés Mauricio, Enriquez-Popayan · Henry Mauricio, Parada-Gereda · José Julian, Bernal-Sanchez

Patient-ventilator asynchrony is common in critically ill patients receiving mechanical ventilation, and timely recognition is essential for safe ventilatory management. However, factors associated with intensive care professionals' ability to identify these events have not been systematically synthesized.To identify a...

Listeria monocytogenes Bacteriophages from Colombia Reveal Putative New Phage Species with Biocontrol Potential

Laura Henao · Laura Morales · Santiago Hernández-Villamizar · Sebastián Chinchilla · y 3 más

In this study, we isolated and characterized novel bacteriophages targeting L. monocytogenes from food-processing environments in Colombia and evaluated their potential as biocontrol agents. Eighteen phages were isolated and initially characterized based on host range and efficiency of plating (EOP), from which, based...

Connecting the missing links: Systematics of the eastern South American species of Josa Keyserling, 1891 (Araneae, Anyphaenidae, Amaurobioidinae)

MARTINEZ, LEONEL · Santos, Adalberto · Cabra-García, Jimmy · Ramirez, Martin

A recent revision of the ghost spider genus Josa Keyserling, 1891 recognized 94 species, with Josa gounellei (Simon, 1897) as the only species recorded from eastern South America. Here, we describe two new species based on specimens of both sexes: Josa minima sp. nov., from Argentina, Brazil, and Paraguay, and Josa pla...

Sodium reduction in cooked meat products without compromising microbiological safety: A predictive microbiology framework for food safety assessment

Juan David, Velasquez-Florez · Catalina, Quevedo-Ospina · Leon F, Toro-Navarro

Sodium plays a critical role in the microbiological stability of cooked meat products, yet regulatory and consumer pressure to reduce sodium intake creates formulation challenges where safety margins are poorly defined. This study quantified the effect of sodium concentration (196-980 mg/100 g), pH, and water activity...

Extended red cell antigen frequencies in a Southwestern Colombian donor population: Implications for phenotype-matched transfusion strategies

Lina Sofia, Castillo · Victor Hugo, Dueñas Rivera · Marcela, Quintero Santacruz

The complex history of genetic admixture in Latin American populations creates unique erythrocyte antigen profiles. This study aimed to determine the extended red blood cell (RBC) antigen frequencies in a blood donor population from Southwestern Colombia, a region with significant African ancestral heritage, to support...

Mitochondrial DNA in lung cancer: From biology to clinical implications

José Lucio-Lozada · Diddier Prada · Luiza Beato-González · Fred R. Hirsch · y 3 más

Mitochondrial DNA (mtDNA) is emerging as a relevant component of the molecular landscape in non-small cell lung cancer (NSCLC). Due to its inherent vulnerability to environmental carcinogens, the mitochondrial genome accumulates alterations-such as D-loop variants and Electron Transport Chain variants- increasingly ide...

Female sex is independently associated with poor health-related quality of life in patients with coronary heart disease across 14 countries: the INTERASPIRE study

Ski, Chantal F. · Thompson, David R. · Jennings, Catriona S. · Kotseva, Kornelia · y 34 más

Optimizing health-related quality of life (HRQoL) is a goal of preventive and therapeutic cardiovascular care worldwide, yet sex disparities in HRQoL remain insufficiently explored at a population level. The objective of this study was to examine sex differences in HRQoL in relation to secondary prevention in patients...

Sotos syndrome: Report of a new pathogenic variant inthe NSD1 gene in an adolescent

Nicolle D, Becerra Páez · Dubán S, Hernández Rodríguez · Leidy A, Forero Cisneros · Gustavo A, Contreras García · y 1 más

Sotos syndrome is a genetic disorder characterized by distinctive facial features, intellectual disability, and excessive growth. It is associated with pathogenic variants in the NSD1 gene, most of which are de novo.We present the case of an 11-year-old girl with overgrowth (height more than 2 standard deviations above...

Mosquito-host blood-meal networks reveal potential arboviral bridge pathways in Colombian Caribbean mangroves

Richard Hoyos-López · Nelson Fernández · Juan Carlos Gallego-Gómez

Mosquito-host feeding networks shape the ecological routes through which arboviruses may move from enzootic cycles toward human-exposure compartments, yet these networks remain largely uncharacterized in Colombian Caribbean mangroves. We analyzed blood-fed female mosquitoes collected in La Balsa, San Bernardo del Vient...
