Lineage 2 West Nile virus (WNV) strains have been implicated in severe encephalitis outbreaks in humans and equines residing in Europe. WNV molecular characterization is important for the development of diagnostic assays, as well as for obtaining molecular information, which is necessary for epidemiological investigations of virus transmission in areas at risk. For whole genome sequencing of lineage 2 WNV strains, directly from biological specimens, a PCR-based NGS protocol was developed. The method was applied in WNV-positive specimens obtained from animal, human and mosquito hosts in Greece. The results of its application indicate that, even in cases of low virus titers, the developed PCR-based NGS approach is able to provide whole genome sequences of lineage 2 WNV strains.

Purpose: Molecular classification of endometrial cancer (EC) has emerged as a key approach to individualize therapy and define prognostic outcomes. This study aimed to implement the traditional ProMisE classification in a Brazilian population, compared with a molecular setting of ProMisE biomarkers, and evaluate its impact on patients' prognosis.
Patient And Methods: A prospective cohort of 114 patients with primary EC treated at Barretos Cancer Hospital (BCH) between October 2020 and December 2022 was conducted.

Measurable residual disease (MRD) testing in patients with acute myelogenous leukemia (AML) represents a heterogenous assessment process designed to quantify leukemia-specific biomarkers that are not ascertainable by routine pathologic evaluation. The most common tools used to assess MRD are multiparameter flow cytometry (MPFC), and polymerase chain reaction (PCR) based tools, including quantitative or digital droplet PCR (qPCR, ddPCR), or next-generation sequencing (NGS) technologies. Collectively, MRD assessments have become an important clinical tool in the management of patients with AML.

Severe pneumonia remains the leading infectious cause of death worldwide. The time-consuming nature and suboptimal sensitivity of sputum cultures hamper prompt pathogen detection for tailored treatments. Advanced techniques such as polymerase chain reaction (PCR) and next-generation sequencing (NGS) offer rapid genetic pathogen detection and identification of antimicrobial resistance (AMR) genes.

Next-generation sequencing (NGS) library construction often requires high-quality DNA extraction, precise adjustment of DNA concentration, and restriction enzyme digestion to reduce genome complexity, which results in increased time and cost in sample preparation and processing. To address these challenges, a PCR-based method for rapid NGS library preparation, named dpMIG-seq, has been developed and proven effective for high-throughput genotyping. However, the application of dpMIG-seq has been limited to diploid and polyploid species with disomic inheritance.

Minimal residual disease (MRD) diagnostics is of high clinical relevance in patients with indolent B-cell non-Hodgkin lymphomas (B-NHL), B-cell chronic lymphocytic leukemia (CLL), and multiple myeloma and serves as a surrogate parameter to evaluate treatment effectiveness and long-term prognosis. Real-time quantitative PCR (RQ-PCR) targeting circulating lymphoma cells is still the gold standard for MRD detection in indolent B-NHL and currently the most sensitive and the most broadly applied method in follicular lymphoma (FL) and mantle cell lymphoma (MCL). Alternatively, droplet digital PCR (ddPCR) can be used for MRD monitoring in multiple myeloma, mantle cell lymphoma, CLL, and FL with comparable sensitivity, accuracy, and reproducibility.
