Therapeutic decision-making in appendiceal abscess: Results of the 2025 Italian Society of Research in Surgery/Italian Society of Emergency and Trauma Surgery consensus conference

Roberto Cirocchi · Matteo Matteucci · Antonia Rizzuto · Giovanni Alemanno · y 54 más

The management of appendiceal abscess remains a challenging area in emergency surgery because of heterogeneity in anatomic presentation, inflammatory severity, and patient physiologic reserve. The absence of standardized pathologic definitions, imaging-based grading systems, and clear escalation criteria has contribute...

The coalescent of a sample from a linear-fractional branching process

Natalia Cardona-Tobón · Sandra Palau

In this article, we focus on Bienaymé-Galton-Watson processes with linear-fractional offspring distributions. At a fixed generation, we consider a sample of the individuals alive, drawn in two different ways: either through Bernoulli sampling, where each individual is selected independently with a given probability, or...

Chikungunya Virus Infection of Monocytes Generates a Persistent Macrophage Reservoir That Promotes IFN-π/IL-27–STAT1- and NF-κB–Driven Chronic Arthritis

Juan Felipe Valdés-López · Y.S Tamayo-Molina · Lady Johana Hernández-Sarmiento · Silvio Urcuqui-Inchima

Chikungunya virus (CHIKV) infection causes acute febrile illness that frequently progresses to chronic arthralgia. Although monocytes are CHIKV targets, whether viral exposure drives their differentiation into macrophages to sustain persistent inflammation remains incompletely understood. To address this, we integrated...

Afrontamiento ante la muerte de pacientes pediátricos en enfermeras de tres instituciones de salud en Cartagena, Colombia

Luis Alfonso Sierra Leguia · Margareth Esther Arzuza Rojano · María Camila Mejía Fuentes · Isabel Cristina Negrete Parra

El objetivo de la investigación busca identificar el nivel de afrontamiento ante la muerte de pacientes pediátricos en enfermeras en Cartagena.

Compositional and Metabolomic Characterization of Major On-Farm Side Streams and Derived Products of Industrial Fine-Flavor Cocoa Processing

Daniela Burgos-Toro · Ana M. León-Inga · María J. Chica · José M. Guillamón · y 2 más

Abstract The fine-flavor cocoa agro-industrial chain generates on-farm side streams with distinct origins and processing histories, yet their compositional diversity remains insufficiently characterized under industrial conditions. Here, we performed an integrated compositional and metabolomic characterization of cocoa...

High-grade gliomas where resources define survival: a systematic review and meta-analysis of outcomes, surgical access, and molecular diagnostic gaps in low- and middle-income countries

Carlos Castillo Rangel · Gervith Reyes Soto · Edinson David Berrio Perea · José De Jesús Gutiérrez-Baños · y 11 más

Background High-grade gliomas remain among the most aggressive tumors in neuro-oncology. Although prognosis is strongly influenced by tumor biology, survival in low- and middle-income countries is also shaped by health-system factors, including delayed diagnosis, limited surgical infrastructure, incomplete adjuvant the...

Electromagnetic Transmission Zeros Filtering Using an Inhomogeneous Photonic Loop

Abdelouahid Ezzarfi · Mimoun El-Aouni · Youssef Ben-Ali · Francis Segovia-Chaves · y 2 más

In this work, we focus on the interface response theory based on Green's function in order to examine the propagation of electromagnetic waves through a symmetrical loop composed of different optical materials. Numerical results show the emergence of transmission very/large zeros modes (TZs) at specific reduced frequen...

Influence of the pelvic bone and gluteal zone over the stress state at the interaction between the prosthetic socket and residual limb for people with transfemoral amputation

Juan Atehortua · Fanny Valencia · Juan Ramírez

The rehabilitation process for people with lower limb amputation represents a substantial socioeconomic, psychological, and functional challenge. Finite element analysis (FEA) has been increasingly used to investigate residual limb–socket interaction; however, the extent to which additional proximal anatomy, beyond the...
