Optimizing the NGS-based discrimination of multiple lung cancers from the perspective of evolution.

Next-generation sequencing (NGS) offers a promising approach for differentiating multiple primary lung cancers (MPLC) from intrapulmonary metastasis (IPM), though panel selection and clonal interpretation remain challenging. Whole-exome sequencing (WES) data from 80 lung cancer samples were utilized to simulate MPLC and IPM, with various sequenced panels constructed through gene subsampling. Two clonal interpretation approaches primarily applied in clinical practice, MoleA (based on shared mutation comparison) and MoleB (based on probability calculation), were subsequently evaluated.

Harnessing the tumor microenvironment: targeted cancer therapies through modulation of epithelial-mesenchymal transition.

The tumor microenvironment (TME) is integral to cancer progression, impacting metastasis and treatment response. It consists of diverse cell types, extracellular matrix components, and signaling molecules that interact to promote tumor growth and therapeutic resistance. Elucidating the intricate interactions between cancer cells and the TME is crucial in understanding cancer progression and therapeutic challenges.

Quantitative IgG response to SARS-CoV-2 membrane protein in infected individuals strongly correlates with lung injury.

The clinical manifestations of SARS-CoV-2 infection may range from asymptomatic or minor conditions to severe and life-threatening outcomes. The respiratory system is a principal target of the virus and in the majority of cases of severe disease, an acute form of pneumonia develops. Despite concerted global efforts to elucidate the pathogenic mechanisms of COVID-19, the progression of the infection leading to pulmonary damage remains poorly understood.

[Experience of a Rapid Diagnostic and Short Stay Unit implemented in Argentina].

Introduction: Rapid diagnostic units (RDUs) represent an alternative to conventional hospitalization diagnosis, enabling outpatient care for patients with suspected potentially severe disease. The first year of operation of a Rapid Diagnostic and Short Stay Unit (RDSSU) is described.

Materials And Methods: Retrospective study involving 696 patients, documenting 739 events defined as each patient's entry into the RDU for specific reasons.
