Linear Mixed-Effects Models in chemistry: A tutorial.

A common goal in chemistry is to study the relationship between a measured signal and the variability of certain factors. To this end, researchers often use Design of Experiment to decide which experiments to conduct and (Multiple) Linear Regression, and/or Analysis of Variance to analyze the collected data. Among the assumptions to the very foundation of this strategy, all the experiments are independent, conditional on the settings of the factors.

Optimizing Wound Care after Surgery of the Head and Neck: A Review of Dressing Materials.

Wound healing is a complex biological process subject to complications that might jeopardize the patient's postoperative care. Appropriately approaching surgical wounds after head and neck surgery positively influences the quality and speed of wound healing and increases patient comfort. A large variety of dressing materials currently exist that allow the care of different types of wounds.

Surgical site complications of isolated salvage neck dissection post-radiotherapy and post-chemoradiotherapy - A cohort analysis (1997-2017).

Introduction: This study aims to quantify surgical site complications (SSC) after isolated salvage neck dissection (ND) compared with primary ND.

Patients And Methods: Between 1997 and 2017 in the Netherlands Cancer Institute - Antoni van Leeuwenhoek, a total of 323 isolated NDs were performed in 308 patients: primary ND (n = 144), post-radiotherapy (RT) ND (n = 53) and post-chemoradiotherapy (CRT) ND (n = 126). Patient, tumor and therapy characteristics were recorded.

Functional and Aesthetic Outcomes of Septal Reconstructions: Results of a Prospective Longitudinal Outcome Study.

In order to correct severe septal deformities, complete septal reconstruction is often required to achieve the desired functional and aesthetic results. Several different techniques have been described. Systematic evaluation of the long-term results is crucial to assess and improve the quality of these surgical techniques.

Clinical Benefits of the Utrecht Questionnaire for Aesthetic Outcome Assessment in Rhinoplasty: An Update.

Presently, there is no consensus on which patient-reported outcome measurement (PROM) instrument is best suited to assess the aesthetic outcomes of rhinoplasty. In this regard, at least seven different validated PROMs are available from the literature, each one with advantages and disadvantages.In this article, we review the development, validation, international translation, and clinical application of the Utrecht Questionnaire (UQ).
