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

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.

Love actually: Is relationship status associated with dark triad personality traits and attitudes towards love?

Romantic love plays a central role in the lives of individuals and influences decisions about lasting relationships such as marriage or cohabitation. To understand the dynamics of intimate relationships, both personality traits and attitudes toward love styles need to be explored. This cross-sectional study aimed to examine the possible differences between married/cohabiting and single individuals in terms of Dark Triad personality traits and attitudes towards love styles, and to investigate which of these factors can significantly predict participants' relationship status.

Paradoxical improvement in exercise tolerance and peak VO2 consumption after treatment with ivabradine and beta-blockers in a patient with mild dilated cardiomyopathy and inappropriate sinus tachycardia-a case report.

Background: Left bundle branch block (LBBB) is a rare conduction disorder in athletes associated with ventricular dyssynchrony, which can lead to left ventricular systolic dysfunction and exercise intolerance. Inappropriate sinus tachycardia (IST) is characterized by an excessive heart rate (HR) that is not related to physiological needs, often resulting in reduced exercise capacity. Managing these conditions in athletes can be challenging, as standard treatments like beta-blockers and ivabradine, while effective in controlling HR, are described to be associated with a reduction in maximal exercise performance.

A multi-omics approach to unravel the interaction between heat and drought stress in the holobiont.

The impact of combined heat and drought stress was investigated in and compared to individual stresses to reveal additive effects and interactions. A combination of plant metabolomics and root and rhizosphere bacterial metabarcoding were used to unravel effects at the plant holobiont level. Hierarchical cluster analysis of metabolomics signatures pointed out two main clusters, one including heat and combined heat and drought, and the second cluster that included the control and drought treatments.

Nonintubated video-assisted thoracic surgery: myth or reality?

Purpose Of Review: This review discusses nonintubated video-assisted thoracic surgery (NIVATS) by presenting its physiological, technical aspects and recent clinical data from the literature.

Recent Findings: In the last two decades, NIVATS has gained traction as an alternative to traditional intubated thoracic surgery, offering potential benefits in terms of reduced complications, faster recovery times, and improved patient satisfaction. Several approaches to this technique have been described in the literature, mainly divided into the awake patient technique (awake-NIVATS) and the asleep patient technique (asleep-NIVATS).

Metformin radiosensitizes OSCC in 2D and 3D models: possible involvement of CAF-1.

Objective: This study investigated metformin as a sensitizer for radiotherapy in oral squamous cell carcinoma (OSCC) to reduce the radiation intensity. It evaluated the drug's effect on Chromatin Assembly Factor-1 (CAF-1) expression, whose high levels correlate with worse prognosis of this cancer.

Methods: The effects of metformin, alone and with radiotherapy, were evaluated on CAL27 (HPV-) and SCC154 (HPV+) OSCC cells.

A Digital Workflow for Automated Assessment of Tumor-Infiltrating Lymphocytes in Oral Squamous Cell Carcinoma Using QuPath and a StarDist-Based Model.

The search for reliable prognostic markers in oral squamous cell carcinoma (OSCC) remains a critical need. Tumor-infiltrating lymphocytes (TILs), particularly T lymphocytes, play a pivotal role in the immune response against tumors and are strongly correlated with favorable prognoses. Computational pathology has proven highly effective for histopathological image analysis, automating tasks such as cell detection, classification, and segmentation.

A machine learning approach to predict HPV positivity of oropharyngeal squamous cell carcinoma.

HPV status is an important prognostic factor in oropharyngeal squamous cell carcinoma (OPSCC), with HPV-positive tumors associated with better overall survival. To determine HPV status, we rely on the immunohistochemical investigation for expression of the P16 protein, which must be associated with molecular investigation for the presence of viral DNA. We aim to define a criterion based on image analysis and machine learning to predict HPV status from hematoxylin/eosin stain.
