Pilot Study to Evaluate a New Method for Endotracheal Administration of Surfactant in Neonatal Respiratory Distress Syndrome: Fiberscope Assisted Surfactant Therapy (FAST).

Introduction: Currently, INSURE (Intubation-Surfactant-Extubation) and LISA (Less Invasive Surfactant Administration) are two recommended techniques for surfactant delivery to newborns with respiratory distress syndrome. The aim of this study was to evaluate the feasibility, safety, tolerability of a new technique of surfactant administration in newborns without anesthesia or laryngoscopy: Fiberscope Assisted Surfactant Therapy (FAST).

Methods: This monocentric, prospective, nonrandomized, pilot feasibility study was conducted from January to December 2021.

How should we diagnose and treat blastic plasmacytoid dendritic cell neoplasm patients?

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive leukemia for which we developed a nationwide network to collect data from new cases diagnosed in France. In a retrospective, observational study of 86 patients (2000-2013), we described clinical and biological data focusing on morphologies and immunophenotype. We found expression of markers associated with plasmacytoid dendritic cell origin (HLA-DRhigh, CD303+, CD304+, and cTCL1+) plus CD4 and CD56 and frequent expression of isolated markers from the myeloid, B-, and T-lymphoid lineages, whereas specific markers (myeloperoxidase, CD14, cCD3, CD19, and cCD22) were not expressed.

Efficacy, safety, and biomarkers of single-agent bevacizumab therapy in patients with advanced hepatocellular carcinoma.

Objective: Hepatocellular carcinoma (HCC) is a highly vascularized tumor in which neoangiogenesis contributes to growth and metastasis. We assessed the safety, efficacy, and potential biomarkers of activity of bevacizumab in patients with advanced HCC.

Methods: In this phase II trial, eligible patients received bevacizumab, 5 mg/kg or 10 mg/kg every 2 weeks.

Quantification of circulating mature endothelial cells using a whole blood four-color flow cytometric assay.

Circulating endothelial cells (CEC) are currently proposed as a potential biomarker for measuring the impact of anti-angiogenic treatments in cancer. However, the lack of consensus on the appropriate method of CEC measurement has led to conflicting data in cancer patients. A validated assay adapted for evaluating the clinical utility of CEC in large cohorts of patients undergoing anti-angiogenic treatments is needed.
