Flow-Through Flaps as a Robust Method for Advanced Free Flap Reconstruction in the Head and Neck: A Multi-Institutional Experience.

Background: Flow-through flaps (FTFs) are an advanced technique in which a free flap is anastomosed to the pedicle of another free flap to reconstruct extensive head and neck defects when recipient vessels are scarce.

Methods: A multi-institutional cohort of FTFs used for head and neck reconstruction were reviewed. For comparison, FTF outcomes were compared to free flaps that required vein grafts (VG) to reach distant recipient vessels.

Benchmarking and performance evaluation of a novel deformable image registration software for radiotherapy CT images.

Purpose: We evaluated and benchmarked a novel deformable image registration (DIR) software functionality (DirOne, Cosylab d.d., Ljubljana, Slovenia) by comparing it to two commercial systems, MIM and VelocityAI, following AAPM task group 132 (TG-132) guidelines.

Effect of cosolvents on the phase separation of polyelectrolyte complexes.

Evidence is shown that cosolvent mixtures control the coacervation of mixtures of oppositely charged polyelectrolytes. Binary and ternary solvent mixtures lead to non-monotonic solubility as a function of the average dielectric constants of the solvent mixtures. These data are rationalized by considering both electrostatic-driven phase separation and solvophobic-driven phase separation using group contribution effects on solubility parameters.

Predicting compatibilized polymer blend toughness.

Polymer blends can yield superior materials by merging the unique properties of their components. However, these mixtures often phase separate, leading to brittleness. While compatibilizers can toughen these blends, their vast design space makes optimization difficult.

Adjuvant Human Papillomavirus Vaccination in Recurrent Respiratory Papilloma Patients Older than 45.

Objectives: The primary objective was to examine the intersurgical interval (ISI) of recurrent respiratory papillomatosis (RRP) in patients older than 45 years before and after a Gardasil vaccination series.

Methods: We conducted a retrospective chart review of adult patients >45 years of age diagnosed with RRP from 2012 to 2022. Patients were excluded if they did not receive at least two doses of the Gardasil vaccine series or if they underwent two or fewer surgeries during the study period.
