Objective: To conduct a point prevalence survey (PPS) of antibiotic use in the main pediatric tertiary-level hospital in Panama City to establish antibiotic prevalence and identify key areas for addressing antimicrobial resistance.
Methods: This point prevalence survey (PPS) conducted in a tertiary-level hospital in Panama followed the Pan American Health Organization's adaptation of the methodology proposed by the World Health Organization for PPSs on antibiotic use. Information obtained included patients' demographic characteristics, antimicrobial prescriptions, indication for antimicrobial use, and prescription's adherence to guidelines.
Article Synopsis
- Liquid-liquid phase separation in the cell nucleus plays a key role in gene regulation, chromatin organization, and DNA repair processes.
- The study utilized lipid-interacting RNA sequencing (LIPRNAseq) and confocal microscopy to explore the interaction of phosphatidylinositol 4,5 bisphosphate (PIP2) with specific RNA, identifying a PIP2-binding RNA motif and its colocalization with long non-coding RNA HANR in the perinucleolar compartment.
- The findings suggest a link between PIP2, lncHANR, and oncogenic super-enhancers, indicating their potential as prognostic markers for cancer and highlighting the importance of understanding lipid metabolism and RNA interactions for future cancer treatment strategies.
Additive Manufacturing (AM) has revolutionized the production of complex three-dimensional (3D) structures; however, the efficient and precise fabrication of thin profiles remains a challenge. This study explores the application of femtosecond-laser-based additive manufacturing techniques for the production of thin profiles with micron-scale features, reaching profile thicknesses below 100 µm. The study investigates the effects of scanning strategy, with optimized processing parameters, on the fabrication of thin profiles; wall thickness measurements were carried out using various technologies to analyse the influence of each on the resulting values.

McGill-R-Thy1-APP transgenic (Tg) rat and 5xFAD Tg mouse models that represent earlier or later disease stages were employed. The animals were exposed to a control diet (CD) or an HFD based on corn oil, from young (rats) or adult (mice) ages for 24 or 10 weeks, respectively.

- The study conducted the first genome-wide association study (GWAS) on sporadic Alzheimer's disease (AD) using a sample from Argentina and Chile, involving 539 patients and 854 controls.
- Combining their findings with data from the European Alzheimer and Dementia Biobank (EADB), researchers identified apolipoprotein E ε4 as a significant genetic risk factor and discovered four new loci linked to AD.
- The research highlights the shared genetic factors affecting AD risk across different populations, while also noting that a genetic risk score (GRS) showed diminishing effectiveness with increasing Native American ancestry.
