Metabolomic in severe traumatic brain injury: exploring primary, secondary injuries, diagnosis, and severity.

Crit Care

January 2025

Department of Critical Care Medicine, Cumming School of Medicine, Health Research Innovation Center (HRIC), University of Calgary, Room 4C64, 3280 Hospital Drive N.W., Calgary, AB, T2N 4Z6, Canada.

Background: Traumatic brain injury (TBI) is a major public health concern worldwide, contributing to high rates of injury-related death and disability. Severe traumatic brain injury (sTBI), although it accounts for only 10% of all TBI cases, results in a mortality rate of 30-40% and a significant burden of disability in those that survive. This study explored the potential of metabolomics in the diagnosis of sTBI and explored the potential of metabolomics to examine probable primary and secondary brain injury in sTBI.

Background: Chronic obstructive pulmonary disease (COPD) and asthma are the two most prevalent chronic respiratory diseases, significantly impacting public health. Utilizing clinical questionnaires to identify and differentiate patients with COPD and asthma for further diagnostic procedures has emerged as an effective strategy to address this issue. We developed a new diagnostic tool, the COPD-Asthma Differentiation Questionnaire (CAD-Q), to differentiate between COPD and asthma in adults.

Call to action for Clinicians in the South-East Asian Regions on Primary Prevention of Diabetes in people with Prediabetes- A Consensus statement.

Diabetes Res Clin Pract

January 2025

Department of Cardiovascular and Metabolic Diseases, Istituto Ricerca Cura Carattere Scientifico Multimedica, Sesto, San Giovanni (MI), Italy.

Primary prevention of diabetes still remains as an unmet challenge in a real world setting. While, translational programmes have been successful in the developed nations, the prevailing social and economic inequities in the low and middle income countries, fail to integrate diabetes prevention into their public health systems. The resulting exponential increase in the prevalence of diabetes and the cost of treatment has put primary prevention in the back seat.

Environmental characteristics drastically shape the host-parasite associations under natural conditions. This is the case of parasites such as avian haemosporidians which naturally infect birds and are transmitted by insect vectors. Landscape characteristics are known to determine the epidemiology of transmission of these parasites in the wild, but the strength of these factors may differ at different spatial scales.

Two Co(II) mixed-ligand metal-organic frameworks (MOFs) based on 2-methylimidazole and trimesate were synthesised at room temperature. The structure and properties of the two MOFs, named material Deutsches Elektronen Synchrotron-1 and -2 (mDESY-1 and mDESY-2), were verified by single crystal X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD), SQUID magnetic susceptibility and N adsorption. The structural analysis indicates that mDESY-1 is a 3D ionic framework with 2-methyl-1-imidazol-3-ium counterions residing in its pores, while mDESY-2 is a 2D neutral framework isostructural to ITH-1, with water as a co-crystallising solvent.

Chemical and Enzymatic Mechanosynthesis of Organocatalytic Peptide Materials Based on Proline and Phenylalanine.

ChemSusChem

January 2025

Universidad de Antioquia Facultad de Ciencias Exactas y Naturales, Instituto de Química, Calle 70 No 52-21, Medellín, NA, Medellín, COLOMBIA.

In recent years, mechanosynthesis of peptides through either chemical or enzymatic routes has been accomplished. In part, this advancement has been driven due to the organocatalytic properties of peptide-based biomaterials. In this work, we report the merging of chemical and enzymatic protocols under mechanochemical conditions to synthesize peptide materials based on L-proline and L-phenylalanine.

Atmospheric corrosion of carbon and galvanized steel under high rainfall conditions.

Heliyon

January 2025

Grupo de Investigación en Energías Renovables y Meteorología-GIERMET, Universidad Tecnológica del Chocó, Cra 22 No 18b -10, Quibdó, Colombia.

The corrosion rates of carbon steel and galvanized steel according to the ISO 9223 standard, the effect of pollutant contamination and atmospheric aggressiveness under high rainfall conditions in the Chocó department were studied. Carbon and galvanized steel samples, chloride, and sulfur collectors were exposed in three atmospheric stations in three strategic positions covering the Colombian Pacific: Quibdó, Andagoya and Bahía Solano, for different exposure periods (up to 18 months). The structural-micro characterization of corrosion products was evaluated via X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy SEM-EDS.

Marijuana poisoning in canines is still considered a taboo topic. Poisoning in pets is becoming increasingly common, in many cases resulting in severe clinical signs, such as ataxia, urinary incontinence, mydriasis, depression, and hyperesthesia. Colombia does not have any reliable test for the diagnosis of exposure to cannabis in animals, and it is not an obligation to report this kind of poisoning to the authorities.

Due to complex interactions, changes in any one area of food systems are likely to impact-and possibly depend on-changes in other areas. Here we present the first annual monitoring update of the indicator framework proposed by the Food Systems Countdown Initiative, with new qualitative analysis elucidating interactions across indicators. Since 2000, we find that 20 of 42 indicators with time series have been trending in a desirable direction, indicating modest positive change.

Variational graph autoencoder for reconstructed transcriptomic data associated with NLRP3 mediated pyroptosis in periodontitis.

Sci Rep

January 2025

Department of Basic Sciences, Faculty of Dentistry, Universidad de Antioquia U de A, Medellín, 050010, Colombia.

The NLRP3 inflammasome, regulated by TLR4, plays a pivotal role in periodontitis by mediating inflammatory cytokine release and bone loss induced by Porphyromonas gingivalis. Periodontal disease creates a hypoxic environment, favoring anaerobic bacteria survival and exacerbating inflammation. The NLRP3 inflammasome triggers pyroptosis, a programmed cell death that amplifies inflammation and tissue damage.

Introduction: Systemic lupus erythematosus (SLE) predominantly affects women, especially during their reproductive years, leading to increased risks during pregnancy. Latina women develop SLE at a younger age, which increases their susceptibility to pregnancy complications such as pre-eclampsia, preterm birth and fetal growth restriction.

Objective: The purpose of this study is to systematically review maternal and fetal outcomes in pregnant Latina women with SLE and to perform a meta-analysis to assess specific risks associated with the disease.

Estimating realized relatedness in free-ranging macaques by inferring identity-by-descent segments.

Proc Natl Acad Sci U S A

January 2025

Department of Primate Behavioral Ecology, Institute of Biology, Leipzig University, Leipzig 04103, Germany.

Biological relatedness is a key consideration in studies of behavior, population structure, and trait evolution. Except for parent-offspring dyads, pedigrees capture relatedness imperfectly. The number and length of identical-by-descent DNA segments (IBD) yield the most precise relatedness estimates.
