Departamento de Ciencias Ecológicas, Facultad de Ciencias, Universidad de Chile, Las Palmeras 3425, Ñuñoa, Santiago 7800003, Chile.

Clarifying the taxonomic status and distribution of endangered species is crucial to their conservation. In this study, we contrasted different lines of evidence (morphology, mtDNA, and nucDNA: microsatellites and SNP) to clarify the taxonomic status of endangered water frog species and unidentified populations that inhabit the Salt Puna in Chile. We studied population differentiation and species divergence by performing morphometric, population genetic and species delimitation analyses.

is the causative agent of atypical vibriosis in salmonids cultured in Chile. While extensive research provides insights into through phenotypic, antigenic, and genetic typing, as well as various virulence mechanisms, proteomic characterization remains largely unexplored. This study aimed to advance the proteomic knowledge of Chilean Vo-LM-18 and its OMVs, which have known virulence.

Urban parks and cemeteries constitute hot spots of bird diversity in urban areas. However, the seasonal dynamics of their bird communities have been scarcely explored at large scales. This study aims to analyze the drivers of urban bird assemblage seasonality in urban parks and cemeteries comparing assemblages during breeding and non-breeding seasons in the Neotropical Region.

Objectives: To explore whether the mean lumbar acceleration is a feasible tool for determining minimum eligibility criteria to compete in cerebral palsy football, differentiating between new sports classes, and to assess the effect of foot contacts on balance evaluation and class distinction.

Design: Cross-sectional study.

Methods: A total of 146 male cerebral palsy footballers classified into FT1 (n=34), FT2 (n=87), and FT3 (n=25), alongside 12 non-impaired athletes as a control group, participated.

Purpose: To compare voiding parameters in women with and without increased postvoid residual (PVR) volume, to correlate these parameters with PVR volume and PVR percentage, and to describe their ability to predict an increased PVR volume.

Methods: Retrospective cross-sectional study of urodynamics data prospectively acquired from consecutive symptomatic women over a 5-year period. Patients with spinal cord disorders and with abdominal straining during voiding (abdominal pressure ≥10 cm H2O over baseline at maximum flow rate [Qmax]) were excluded.

Introduction: Patient-centered communication is an essential skill in nursing, particularly in the care of older adult patients. However, generation Z nursing students, who primarily communicate through digital platforms, face unique challenges in adapting to traditional face-to-face communication with older adults. As a result, there is a need for teaching methods that align with this generation's learning style to enhance their communication skills.

Stigma and discrimination-based narratives have been associated with adverse health outcomes. Migrants and refugees face multiple barriers to accessing healthcare, influenced by stigma and discrimination-based narratives against them. We conducted a scoping review of scientific and grey literature (n = 61) to discuss available evidence in Latin America and the Caribbean (LAC) concerning communication and narrative speeches related to international migration and its implications for population health, particularly when associated with stigma and discrimination against migrants and refugees.

Objective: The aim of this scoping review is to map the concept of resilience and its measurement along with co-occurring theoretical constructs within nursing research using the COVID-19 pandemic as a critical date range for the current evidence.

Introduction: Resilience has a wide variety of definitions in research literature and is often measured through its co-occurring theoretical constructs. Nurse resilience is a key element in interventions targeting nurse well-being and has been tied to burnout and mental health.

Heterozygous pathogenic variants in MBD5 (MIM*611472) and CCM2 (MIM*607929) cause autosomal dominant intellectual developmental disorder 1 (MIM#156200) and cerebral cavernous malformations-2 (MIM#603284), respectively. Both conditions may present with seizures, epilepsy, and status epilepticus. However, super-refractory status epilepticus, defined as seizures lasting more than 24 h, has not been described in either condition.

Effective targeting of somatic cancer mutations to enhance the efficacy of cancer immunotherapy requires an individualized approach. Autogene cevumeran is a uridine messenger RNA lipoplex-based individualized neoantigen-specific immunotherapy designed from tumor-specific somatic mutation data obtained from tumor tissue of each individual patient to stimulate T cell responses against up to 20 neoantigens. This ongoing phase 1 study evaluated autogene cevumeran as monotherapy (n = 30) and in combination with atezolizumab (n = 183) in pretreated patients with advanced solid tumors.

Introduction: therapeutic equivalence has been established in the effectiveness of peripheral nerve blocks in the management of pain in the postoperative period of anterior cruciate ligament reconstruction. However, it is unknown whether this effect is modulated by the anesthesiologist's experience. The objective was to describe the effectiveness of peripheral nerve blocks during the first 24 hours of the postoperative period, considering patient characteristics and the anesthesiologist's experience.

Effects of two training workshops upon university students' learning of critical thinking.

PLoS One

January 2025

Basic psychology, psychobiology and methodology of behavioral sciences, University of Salamanca, Salamanca, Spain.

We evaluated the effect of two workshops on learning about critical thinking amongst first- year university students. 66 Chilean pedagogy students participated, all female, with ages ranging between 18 and 37 years. Two experimental groups were organized, one with direct teaching (n = 22) and another one with semi-directed teaching (n = 19), plus a control group (n = 25).

Advancing Parkinson's diagnosis: seed amplification assay for α-synuclein detection in minimally invasive samples.

Mol Cell Biochem

January 2025

Neurodegenerative Diseases Laboratory, Center for Biomedicine, Universidad Mayor, Avenida Alemania 0281, 4780000, Temuco, La Araucanía, Chile.

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by tremor, rigidity, and bradykinesia, beginning with early loss of dopaminergic neurons in the ventrolateral substantia nigra and advancing to broader neurodegeneration in the midbrain. The clinical heterogeneity of PD and the lack of specific diagnostic tests present significant challenges, highlighting the need for reliable biomarkers for early diagnosis. Alpha-synuclein (α-Syn), a protein aggregating into Lewy bodies and neurites in PD patients, has emerged as a key biomarker due to its central role in PD pathophysiology and potential to reflect pathological processes.

Facultad de Medicina, Universidad del Desarrollo, Santiago, Chile.

Throughout the 20th century, radiographs and fluoroscopies became essential elements to complete clinical evaluation. Images of the most relevant cases, together with their clinical records, were stored in the radiological collections of the hospitals. Over time, the need for physical space due to the emergence of new equipment, together with the digitization of radiographs and their digital storage, put an end to the collections, many of which were lost in a corner of modern X-ray services.

[Parenteral nutrition in neonatology and pediatrics: physicochemical stability, risks and precautions. Narrative review].

Andes Pediatr

October 2024

Departamento de Gastroenterología y Nutrición Pediátrica, Facultad de Medicina, Pontificia Universidad Católica de Chile, Santiago, Chile.

Parenteral nutrition is a high-risk therapy due to some of its components and the exceptional inclusion of drugs. It can contain more than 50 nutrients, with different characteristics of osmolarity, ionic charge, and pH, which can affect its physicochemical stability. In addition, environmental conditions such as light, temperature, and oxygen must be considered.
