Article Synopsis
  • * A study was conducted with 38 fusion-positive NSCLC samples, comparing NGS with FISH and RT-PCR, revealing that while NGS identified all cases, some fusions were missed by FISH and RT-PCR, highlighting limitations in these lesser methods.
  • * The findings suggest that understanding the strengths and weaknesses of different testing techniques is crucial for improving clinical protocols, reinforcing the need for NGS as the primary approach to ensure accurate fusion detection

This study delves into the biomolecular mechanisms underlying the antitumoral efficacy of a hybrid nanosystem, comprised of a silver core@shell (Ag@MSNs) functionalized with transferrin (Tf). Employing a SILAC proteomics strategy, we identified over 150 de-regulated proteins following exposure to the nanosystem. These proteins play pivotal roles in diverse cellular processes, including mitochondrial fission, calcium homeostasis, endoplasmic reticulum (ER) stress, oxidative stress response, migration, invasion, protein synthesis, RNA maturation, chemoresistance, and cellular proliferation.

Association between neutrophil to lymphocyte ratio and inflammatory biomarkers in patients with a first episode of psychosis.

J Psychiatr Res

April 2024

Centro de Investigación Biomédica en Red de Salud Mental, Instituto de Salud Carlos III (CIBERSAM), Spain; Departamento de Farmacología y Toxicología, Facultad de Medicina, Univ. Complutense de Madrid, Instituto de Investigación Sanitaria Hospital 12 de Octubre (i+12), IUIN, Madrid, Spain.

Neutrophil to lymphocyte ratio (NLR) has been proposed as an emerging marker of the immune system alterations in psychotic disorders. However, it is not entirely clear whether NLR elevation is a characteristic of the psychotic disorder itself, which inflammatory pathways activation is detecting, or which possible confounding variables could alter its interpretation. We aimed to analyze the relationship of NLR values with a panel of inflammatory and oxidative/nitrosative stress biomarkers and main potential confounding factors in a well-characterized cohort of 97 patients with a first episode of psychosis (FEP) and 77 matched healthy controls (HC).

Exploring the degradation behaviour of biomaterials in a complex in vitro physiological environment can assist in predicting their performance in vivo, yet this aspect remains largely unexplored. In this study, the in vitro degradation over 12 weeks of porous poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) bone scaffolds in human osteoblast (hOB) culture was investigated. The objective was to evaluate how the presence of cells influenced both the degradation behaviour and mechanical stability of these scaffolds.

Myelodysplastic neoplasms (MDS) are a heterogeneous group of hematological stem cell disorders characterized by dysplasia, cytopenias, and increased risk of acute leukemia. As prognosis differs widely between patients, and treatment options vary from observation to allogeneic stem cell transplantation, accurate and precise disease risk prognostication is critical for decision making. With this aim, we retrieved registry data from MDS patients from 90 Spanish institutions.

Article Synopsis
  • A study conducted from 2017-2020 at five cardiac intensive care units (C-ICUs) found that influenza was detected in 5.5% of patients admitted during flu season, highlighting the potential for underdiagnosis.
  • Patients with influenza often had conditions like heart failure and required mechanical ventilation, with higher instances of myocarditis and pericarditis compared to those without influenza.
  • Despite a significant vaccination uptake (43% of patients), the findings suggest that routine screening for influenza is necessary at C-ICU admissions during influenza epidemics.
