Searching for HI around MHONGOOSE galaxies via spectral stacking

INDEXACION SCOPUSThe observed star formation rates of galaxies in the Local Universe suggests that they are replenishing their gas reservoir across cosmic time. Cosmological simulations predict that this accretion of fresh gas can occur in a hot or a cold mode, yet the existence of low column density (∼1017 cm−2) neutral atomic hydrogen (Hi) tracing the cold mode has not been unambiguously confirmed by observations. We present the application of unconstrained spectral stacking to attempt to detect the emission from this Hi in the circumgalactic medium (CGM) and intergalactic medium (IGM) of six nearby star-forming galaxies from the MHONGOOSE sample for which full-depth observations are available. Our stacking procedure consists of a standard spectral stacking algorithm coupled with a one-dimensional spectral line finder designed to extract a reliable signal close to the noise level. In agreement with previous studies, we find that the amount of signal detected outside the Hi disk is much smaller than implied by simulations. Furthermore, the column density limit that we achieve via stacking (∼1017 cm−2) suggests that direct detection of the neutral CGM and IGM component might be challenging in the future, even with the next generation of radio telescopes. © The Authors 2025

A Systematic Review of Anatomical Variations of the Inferior Thyroid Artery: Clinical and Surgical Considerations

Indexación: Web of Science.Background/Objectives: The inferior thyroid artery (ITA) is an essential component of the thyroid gland's vasculature, with significant clinical and surgical implications due to its anatomical variability. This systematic review aimed to describe the prevalence of ITA anatomical variants and their association with clinical conditions or surgical implications. Methods: A comprehensive search was conducted in MEDLINE, Web of Science, Google Scholar, CINAHL, Scopus, and EMBASE on 20 November 2025. Eligibility criteria included studies reporting on the presence of ITA variants and their correlation with pathologies. Two authors independently screened the literature, extracted data, and assessed methodological quality using the AQUA and JBI tools. Results: Of the 2647 articles identified, 19 studies involving 1118 subjects/cadavers were included. Variations in ITA origin, absence, and additional arteries were reported, with the most common variant being direct origin from the subclavian artery. Clinically, these variations were associated with increased risk of intraoperative hemorrhage, potential nerve damage, and challenges in preoperative planning, particularly during thyroidectomy and other neck procedures. Conclusions: Understanding the anatomical diversity of the ITA is crucial for reducing surgical risks and improving patient outcomes. The review highlighted the need for more standardized research protocols and comprehensive data reporting to enhance the quality of evidence in this domain. Preoperative imaging and thorough anatomical assessments tailored to individual patient profiles, considering ethnic and gender-related differences, are essential for safe surgical interventions in the thyroid region.https://www-webofscience-com.recursosbiblioteca.unab.cl/wos/woscc/full-record/WOS:00154990120000

Relationship Between the Use of Screens and the Motor Development of Children from 8 to 10 Years of Age

Indexación Scopus.Background: The considerable increase in screen exposure causes negative effects on the motor development of boys and girls, which results in a decrease in the level of physical activity and an increase in sedentary behaviors. In Chile, this problem has been widely addressed in adolescence; however, it is necessary to address it in childhood and early adolescence with a preventive approach. Objectives: To know the relationship between the use of screens and motor development in children. Methods: The sample was composed of 206 boys and girls (girls = 126 and boys = 80). The ages of the students ranged from 8 to 10 years old with a mean in months of 89.6 ± 7.54. The Gross Motor Development-2 was applied to identify motor development, screen time was measured using the Questionnaire to measure physical activity and sedentary behavior. Results: Girls have a greater weekly time than females in the use of consoles (p = 0.004). Girls and boys who are in the very poor, poor, and low average levels of motor development have more time in front of TV, PC, consoles, and total time with screens. There is an inverse relationship between the level of motor development and weekly screen time (r = −0.252). Conclusions: Screen exposure has a negative effect on the motor development of boys and girls. Although there is compliance with World Health Organization recommendations for screen exposure, the motor development of the participants is mostly very poor, poor, and low average.https://www.mdpi.com/2227-9067/12/5/58

Consensus statement on standardizing CGM evaluation metrics in Latin America: an expert approach

Indexación Scopus.Background: Latin America has no accepted performance standards for continuous glucose monitoring (CGM) technology evaluation. This has resulted in the emergence of various CGM devices in the market that do not meet strict quality, accuracy, reliability or safety standards. CGM systems are crucial for managing diabetes, as they provide frequent glucose measurements and help detect hypoglycemia or hyperglycemia episodes or even predict these events. Ensuring the reliability and accuracy of CGM devices is essential for patient safety. This consensus statement aims to establish a consensus-driven framework of expert recommendations regarding the metrics that should be evaluated to achieve high standards in CGM devices. Materials and methods: A modified Delphi methodology was employed, engaging endocrinologists, pediatric endocrinologists and diabetologists from Latin America. Experts participated in multiple rounds of surveys and discussions to reach consensus on key characteristics measures, including accuracy thresholds, clinical validation protocols, and post-market surveillance requirements. Quantitative and qualitative data were analyzed to ensure robust recommendations. Results: The expert panel identified major gaps in existing CGM regulations and established 12 key recommendations and one checklist to align Latin American standards with international best practices. These included the implementation of minimum accuracy thresholds, the adoption of standardized clinical validation protocols, and the enforcement of post-market surveillance measures. The panel also emphasized the importance of patient education, healthcare provider involvement in decision-making, and accessibility to enhance CGM adoption and usability. We underscore the necessity of these measures to improve patient outcomes, patient safety, and regulatory consistency in the region, while also enhancing CGM reliability and accuracy. Conclusion: This consensus statement highlights the urgent need for a standardized metrics to evaluate CGM devices in Latin America. Implementing standardized accuracy requirements, rigorous validation protocols, and enhanced patient education will ensure device reliability, improve clinical outcomes, and foster a more equitable healthcare landscape for diabetes management in the region.https://link.springer.com/article/10.1186/s13098-025-01851-0?utm_source=getftr&utm_medium=getftr&utm_campaign=getftr_pilot&getft_integrator=scopu

Indexación: Scopus.This study examines job satisfaction among mobile digital platform workers in Chile, addressing the gap in understanding the interplay between autonomy, social support, and technology in the platform economy. It explores how these factors shape job satisfaction through the following research question: How do autonomy, social support, and technological factors influence job satisfaction in the platform economy? Using a quantitative methodology, 398 platform workers from three Chilean regions participated in a survey, with data analyzed via logistic regression models to evaluate the impact of sociodemographic and psychological variables. The findings highlight that autonomy and social support significantly enhance job satisfaction, while technological usability and transformation are pivotal for positive work experiences. The study concludes that fostering worker autonomy, robust support systems, and user-friendly technologies is critical for improving job satisfaction in the gig economy. These insights contribute to the academic literature and inform strategies for policymakers and platform operators, emphasizing the need for tailored approaches to enhance worker well-being and organizational outcomes. © 2025 by the authorshttps://www.mdpi.com/2071-1050/17/2/53

SNX5 promotes antigen presentation in B cells by dual regulation of actin and lysosomal dynamics

Indexación: Scopus.B cells rapidly adapt their endocytic pathway to promote the uptake and processing of extracellular antigens recognized through the B-cell receptor (BCR). The mechanisms coupling changes in endomembrane trafficking to the capacity of B cells to screen for antigens within lymphoid tissues remain unaddressed. We investigated the role of SNX5, a member of the sorting nexin family, which interacts with endocytic membranes to regulate vesicular trafficking and macropinocytosis. Our results show that in steady state, B cells form SNX5-rich protrusions at the plasma membrane, which dissipate upon interaction with soluble antigens, whereas B cells activated with immobilized antigens accumulate SNX5 at the immune synapse where it regulates actin-dependent spreading responses. B cells silenced for SNX5 exhibit enlarged lysosomes, which are not recruited to the synaptic membrane, decreasing their capacity to extract immobilized antigens. Overall, our findings reveal that SNX5 is critical for actin-dependent plasma membrane remodeling in B cells in-volved in antigen screening and immune synapse formation, as well as endolysosomal trafficking required to promote antigen extraction and presentation. © 2024 Cabrera-Reyes et alhttps://www.life-science-alliance.org/content/8/1/e20240291

The barriers perceived by Chilean athletes with disability at different social ecological levels

Indexación: Scopus.People with disabilities face various barriers that hinder or prevent access to physical activity, impacting their quality of health and life. This study aimed to examine the barriers to physical activity experienced by Chilean athletes with disability. The sample consisted of 35 Chilean athletes with disability. The participants answered the Physical Activity Questionnaire for People with Mobility Impairments (BPAQ-MI) to assess perceptions of social ecological subdivided into four levels. Sex, the type of sport practice, the region where live, the type of disability, and the physical disability were considered. The organizational level was the main barrier according to the ecological level, with the lack of adaptation of outdoor spaces and the lack of information or inclusive advertising in the sports center being the main barriers identified. An effect of the type of disability on the social ecological barriers was observed, with differences between the non-wheelchair user and wheelchair user groups. The organizational and community context were the main perceived barriers. Thus, it is considered relevant to generate actions for specific interventions in order to promote the practice of physical activity and reduce the main barriers identified in the different contexts within the community. © The Author(s) 2025.https://www.nature.com/articles/s41598-025-04211-0Funding text This study has been partially supported by the funding for research groups (GR21149) granted by the Government of Extremadura (Employment and infrastructure office\u2014Consejer\u00EDa de Empleo e Infraestructuras), with the contribution of the European Union through the European Regional Development Fund (ERDF) by the Optimisation of Training and Sports Performance Research Group (GOERD) of the Faculty of Sports Sciences of the University of Extremadura.

Psychometric Validation of the Spanish OSAKA Questionnaire: A Cross-Sectional Study Among Colombian Dental Professionals

Indexación: Web of Science.Objectives: To evaluate the psychometric properties of the Spanish version of the obstructive sleep apnea knowledge and attitudes (OSAKA) questionnaire among dental professionals in Colombia. Methods: A cross-sectional study was conducted in Manizales, Colombia, between January and June 2024. A total of 120 dental professionals, including general dentists, specialists, residents, and academic clinicians, were selected through stratified random sampling. Participants completed the Spanish-adapted OSAKA questionnaire and a structured sociodemographic survey. Internal consistency was assessed using Cronbach's alpha (alpha) and McDonald's Omega (Omega). Construct validity was examined through exploratory factor analysis (EFA), with Kaiser Meyer Olkin (KMO) values and Bartlett's test. Results: The knowledge subscale (18 items) showed good reliability (alpha = 0.83; Omega = 0.83), while the attitude subscale (5 items) showed near-acceptable reliability (alpha = 0.68; Omega = 0.59). KMO values were 0.79 for knowledge and 0.57 for attitudes; Bartlett's test was significant in both cases (p 1 explained 61.66% of the variance for knowledge, and two components explained 79.49% for attitudes. Significant differences in attitude scores were found among professional groups (p <= 0.001, eta(2) = 0.13), with specialists scoring highest (X = 17.66) and general dentists lowest (X = 14.62). Knowledge scores did not significantly differ between groups (p = 0.47). Conclusions: The Spanish OSAKA questionnaire is a valid and reliable tool to assess knowledge and attitudes toward obstructive sleep apnea in Colombian dental professionals. Its use may support improved education, screening, and interdisciplinary collaboration in dental settings.https://www-webofscience-com.recursosbiblioteca.unab.cl/wos/woscc/full-record/WOS:00153679830000

A Multi-wavelength Characterization of the 2023 Outburst of MAXI J1807+132: Manifestations of Disk Instability and Jet Emission

Indexación: Web of Science.Several phenomenological aspects of low-luminosity neutron star transients, such as atolls, remain poorly understood. One such source, MAXI J1807+132, entered its latest outburst in 2023 July. To thoroughly characterize this outburst, we conducted an extensive observational campaign spanning radio to X-ray wavelengths. Here we present the results of this campaign, which covered the period from before the outburst to the return to quiescence. We detected a delay between the X-ray and optical rise times, which is consistent with the predictions of the disk instability model with a truncated disk. The color evolution and optical/X-ray correlations, along with infrared and radio detections, support the presence of jet synchrotron emission during the gradual decay phase following the peak. We also report for the first time in an X-ray binary a near-orthogonal rotation of the optical polarization just before a small flare, after which the jet is thought to be quenched. The main outburst is followed by several high-amplitude, rapid reflares in the optical, ultraviolet, and X-ray bands, the origin of which remains difficult to constrain.https://www-webofscience-com.recursosbiblioteca.unab.cl/wos/woscc/full-record/WOS:00153349750000

MINCE: III. Detailed chemical analysis of the UVES sample

Indexación: Scopus.Context. The Measuring at Intermediate Metallicity Neutron-Capture Elements (MINCE) project aims to provide high-quality neutron-capture abundances measurements for several hundred stars at an intermediate metallicity of -2.5 < [Fe/H] < -1.5. This project will shed light on the origin of the neutron-capture elements and the chemical enrichment of the Milky Way. Aims. The goal of this work is to chemically characterize the second sample of the MINCE project and compare the abundances with the galactic chemical evolution model at our disposal. Methods. We performed a standard abundance analysis based on one-dimensional (1D) local thermodynamic equilibrium (LTE) model atmospheres based on high-resolution and high-signal-to-noise-ratio (S/N) spectra from Ultraviolet and Visual Echelle Spectrograph (UVES). Results. We provide the kinematic classification (i.e., thin disk, thick disk, thin-to-thick disk, halo, Gaia Sausage Enceladus, Sequoia) of 99 stars and the atmospheric parameters for almost all stars. We derived the abundances for light elements (from Na to Zn) and neutron-capture elements (Rb, Sr, Y, Zr, Ba, La, Ce, Pr, Nd, Sm, and Eu) for a subsample of 32 stars in the metallicity range of -2.5 < [Fe/H] < -1.00. In the subsample of 32 stars, we identified eight active stars exhibiting (inverse) P-Cygni profile and one Li-rich star, CD 28-11039. We find a general agreement between the chemical abundances and the stochastic model computed for the chemical evolution of the Milky Way halo for elements Mg, Ca, Si, Ti, Sc, Mn, Co, Ni, Zn, Rb, Sr, Y, Zr, Ba, La, and Eu. Conclusions. The MINCE project has already significantly increased the number of neutron-capture elements measurements in the intermediate metallicity range. The results from this sample are in perfect agreement with the previous MINCE sample. The good agreement between the chemical abundances and the chemical evolution model of the Galaxy supports the nucleosynthetic processes adopted to describe the origin of the n-capture elements. © The Authors 2025.https://www.aanda.org/articles/aa/full_html/2025/03/aa52964-24/aa52964-24.htmlFunding text 1 Support for the author F.L. is provided by CONICYT- 118 PFCHA/Doctorado Nacional a\u00F1o 2020-folio 21200677.
