Epitope-focused immunogens targeting the hepatitis C virus glycoproteins induce broadly neutralizing antibodies.

Hepatitis C virus (HCV) infection causes ~290,000 annual human deaths despite the highly effective antiviral treatment available. Several viral immune evasion mechanisms have hampered the development of an effective vaccine against HCV, among them the remarkable conformational flexibility within neutralization epitopes in the HCV antigens. Here, we report the design of epitope-focused immunogens displaying two distinct HCV cross-neutralization epitopes.

Air pollution exposure and head and neck cancer incidence.

To investigate air pollution's effect in the form of PM (particulate matter measuring less than 2.5 microns) on head and neck aerodigestive cancer incidence, an epidemiological cohort analysis was performed using data from the Surveillance Epidemiology and End Results national cancer database from the years 2002-2012. The relationship between US county mean PM levels and head and neck cancer (HNC) incidence rates were examined using a linear mixed model.

A Process Evaluation Approach to Central Line-Associated Bloodstream Infection Reduction in a Neonatal Population.

Objective: To reduce the rate of central line-associated bloodstream infections (CLABSI) in the M Health Fairview Neonatal Intensive Care Unit (NICU) from 2.15 infections per 1,000 central line days to less than one per 1,000 line days using process evaluation.

Methods: An interdisciplinary team used process mapping and Failure Modes and Effects Analysis (FMEA) to identify root causes and improvement opportunities in central line maintenance.

The Prognostication of Surgically Resected Head and Neck Squamous Cell Carcinoma Using Pre-Therapy Neutrophil and Lymphocyte Counts.

Background: Hematological markers, such as neutrophils (ANC), lymphocyte (ALC), and neutrophil-lymphocyte ratio (NLR), may serve as indicators of systemic inflammation and immune response in head and neck squamous cell carcinoma (HNSCC). However, their prognostic significance across HNSCC subtypes remains to be fully elucidated.

Methods: We conducted a secondary analysis of a randomized clinical trial involving patients with surgically resected HNSCC with either positive margins or extranodal extension.

Environmentally Controlled Microfluidic System Enabling Immune Cell Flow and Activation in an Endothelialised Skin-On-Chip.

Integration of reconstructed human skin (RhS) into organ-on-chip (OoC) platforms addresses current limitations imposed by static culturing. This innovation, however, is not without challenges. Microfluidic devices, while powerful, often encounter usability, robustness, and gas bubble issues that hinder large-scale high-throughput setups.
