The survival grip-how cell adhesion promotes tumor maintenance within the microenvironment.

Cell adhesion is warranted by proteins that are crucial for the maintenance of tissue integrity and homeostasis. Most of these proteins behave as receptors to link adhesion to the control of cell survival and their expression or regulation are often altered in cancers. B-cell malignancies do not evade this principle as they are sustained in relapsed niches by interacting with the microenvironment that includes cells and their secreted factors.

Methicillin-Resistant Staphylococcus aureus Nasal Screening With Polymerase Chain Reaction for Early De-escalation of Empiric Vancomycin in the Treatment of Suspected/Confirmed Respiratory Infection in Critically Ill Patients.

Background: Vancomycin empirically for methicillin-resistant Staphylococcus aureus (MRSA) pneumonia coverage often is prolonged. With high negative predictive value for MRSA pneumonia, we evaluated the efficacy of MRSA nasal screening with polymerase chain reaction for early de-escalation of empiric vancomycin for treatment of respiratory infections in patients admitted to the intensive care units.

Study Question: The impact of MRSA nasal screening on early de-escalation of vancomycin for respiratory infections.

Apomorphine for prolonged disorders of consciousness: a multimodal open-label study.

Background: Apomorphine is a dopaminergic candidate therapy to improve recovery in patients with prolonged disorders of consciousness (PDoC). Behavioural improvements were previously described in non-controlled case series, but its efficacy and neural mechanisms remain largely unknown. This open-label controlled study using multimodal outcome measures investigates the action of apomorphine in severely brain-injured patients.

Exploring Lysophosphatidylcholine as a Biomarker in Ischemic Stroke: The Plasma-Brain Disjunction.

Lipids and their bioactive metabolites, notably lysophosphatidylcholine (LPC), are increasingly important in ischemic stroke research. Reduced plasma LPC levels have been linked to stroke occurrence and poor outcomes, positioning LPC as a potential prognostic or diagnostic marker. Nonetheless, the connection between plasma LPC levels and stroke severity remains unclear.
