Genomics-based timely detection of dengue virus type I genotypes I and V in Uruguay.

Heliyon

November 2024

Laboratorio de Virus Emergentes/reemergentes. Unidad de Virología, Departamento de Laboratorios de Salud Pública, Portugal.

This study details a genomics-based approach for the early detection of mosquito-borne pathogens, marked by Uruguay's first ever complete genomic sequencing of Dengue Virus type I genotypes I and V. This pioneering effort has facilitated the prompt identification of these genotypes within the country, enabling Uruguayan public health authorities to develop timely and effective response strategies. Further integrated into this approach is a climate-driven suitability measure, closely associated with Dengue case reports and indicative of the local climate's role in the virus's transmission in the country within the changing climate context.

DMEK Surgical Strategy in Aphakic and Vitrectomized Eyes.

Eur J Ophthalmol

January 2025

Cornea and Refractive Surgery Unit, Instituto de Microcirugía Ocular (IMO), Barcelona, 08035, Spain.

Article Synopsis
  • After 15 years of DMEK experience, the technique has shown high success rates but still struggles with certain eye conditions like aphakia and eyes that have had vitrectomy.
  • A new method involves injecting an air bubble under the Descemet membrane graft to help unroll it more efficiently during surgery.
  • This approach has been found to decrease surgical time while ensuring successful attachment of the graft, offering a promising option for complex DMEK cases.

Human asthenozoospermia: Update on genetic causes, patient management, and clinical strategies.

Andrology

January 2025

Institute for Advanced Biosciences, INSERM U 1209, CNRS UMR 5309, Université Grenoble Alpes, Team "Physiopathology and Pathophysiology of Sperm Cells", Grenoble, France.

Background: In mammals, sperm fertilization potential relies on efficient progression within the female genital tract to reach and fertilize the oocyte. This fundamental property is supported by the flagellum, an evolutionarily conserved organelle, which contains dynein motor proteins that provide the mechanical force for sperm propulsion and motility. Primary motility of the sperm cells is acquired during their transit through the epididymis and hyperactivated motility is acquired throughout the journey in the female genital tract by a process called capacitation.

The repurposing of statins as neuroprotective agents and/or anti-brain tumor drugs is limited by challenges in brain bioavailability and systemic off-target effects. Therefore, improved and targeted delivery of statins to the brain is necessary. This study aimed to develop a high-strength liquid formulation of the poorly soluble prodrug simvastatin for intranasal administration, as a strategy to achieve high brain concentrations of the prodrug and/or its active form, tenivastatin.

This study aimed to investigate the moderating effect of frailty on the relationship between cognition and symptoms of depression in individuals aged ≥65 and to explore differences between four European regions (West, North, South, and East). A cross-sectional analysis was conducted with 29,094 participants (16,365 women) from 27 countries, aged ≥65 years, who responded to wave 8 of the SHARE project. The variables analysed were depression (12-item EURO-D scale), frailty, and a general cognition index (CogId).

Equine endometrosis is a major cause of infertility in mares and is characterized by degenerative, functional and fibrotic changes in the endometrium with increased collagen (COL) deposition. Transforming growth factor (TGF)-β1 is one of the major pro-fibrotic factors involved in the excessive deposition of extracellular matrix (ECM) components in the equine endometrium. It has been demonstrated that ovarian steroids, specifically 17β-estradiol (E2) and progesterone (P4), not only regulate the cyclicity of the estrous cycle, but also have been implicated as anti- or pro-fibrotic factors.

Association between lifestyle risk factors and mortality in the Mexico City prospective study.

Sci Rep

January 2025

Escuela de Ciencias de la Actividad Física, el Deporte y la Salud, Universidad de Santiago de Chile (USACH), Santiago, Chile.

Unhealthy lifestyles risk factors, such as smoking, alcohol consumption, physical inactivity, poor diet, and obesity, have been associated with a higher risk of all-cause and cause-specific mortality. However, composite score of these unhealthy behaviours has not been considered, particularly in Latin American populations. Herein, we examined the association of lifestyle risk factors score with all-cause and cause-specific mortality in Mexican adults.

For the protozoan parasite Leishmania, completion of its life cycle requires sequential adaptation of cellular physiology and nutrient scavenging mechanisms to the different environments of a sand fly alimentary tract and the acidic mammalian host cell phagolysosome. Transmembrane transporters are the gatekeepers of intracellular environments, controlling the flux of solutes and ions across membranes. To discover which transporters are vital for survival as intracellular amastigote forms, we carried out a systematic loss-of-function screen of the L.

The nucleus accumbens (NAc) is a key brain region for motivated behaviors, yet how distinct neuronal populations encode appetitive or aversive stimuli remains undetermined. Using microendoscopic calcium imaging in mice, we tracked NAc shell D1- or D2-medium spiny neurons' (MSNs) activity during exposure to stimuli of opposing valence and associative learning. Despite drift in individual neurons' coding, both D1- and D2-population activity was sufficient to discriminate opposing valence unconditioned stimuli, but not predictive cues.

Wall teichoic acids (WTAs) from the major Gram-positive foodborne pathogen Listeria monocytogenes are peptidoglycan-associated glycopolymers decorated by monosaccharides that, while not essential for bacterial growth, are required for bacterial virulence and resistance to antimicrobials. Here we report the structure and function of a bacterial WTAs rhamnosyltransferase, RmlT, strictly required for L. monocytogenes WTAs rhamnosylation.

[Medication Reconciliation in Primary Care: Practices, Knowledge and Attitudes in the Lisbon and Tagus Valley Health Region].

Acta Med Port

January 2025

Laboratório de Farmacologia Clínica e Terapêutica. Faculdade de Medicina. Universidade de Lisboa. Lisboa; Instituto de Medicina Molecular João Lobo Antunes. Lisboa. Portugal.

Introduction: Despite the importance of medication reconciliation for the continuity of care, there is currently no information on the practices, knowledge, and attitudes of Portuguese family doctors on this subject. This study aimed to characterize the formal medication reconciliation procedures in the Lisbon and Tagus Valley Health Region, as well as the perception of family doctors in this region about what they know, how they think and how they practice medication reconciliation.

Methods: We conducted an observational, cross-sectional and descriptive study, using two observation units: primary health care units (study 1) and family doctors (study 2) in the Lisbon and Tagus Valley Health Region.

Article Synopsis
  • The Portuguese clinical guidelines recommend 24 hours of hospital monitoring for patients with traumatic brain injuries, even when initial CT scans are normal, despite evidence suggesting this may be unnecessary and potentially harmful.
  • A study analyzed the costs and outcomes of this practice, comparing data from 440 patients admitted in 2022, where only 0.5% developed new intracranial lesions during a 24-hour observation period and one patient (0.2%) died from unrelated causes.
  • The current monitoring protocol cost €163,157, significantly more than the hypothetical scenario of discharging patients after an initial normal CT scan, which would have cost €29,480, highlighting a difference of €133,677.
