Objectives: To develop proof-of-concept algorithms using alternative approaches to capture provider sentiment in ICU notes.

Design: Retrospective observational cohort study.

Setting: The Multiparameter Intelligent Monitoring of Intensive Care III (MIMIC-III) and the University of California, San Francisco (UCSF) deidentified notes databases.

Objectives/hypothesis: To quantify the degree of color match achieved during microvascular facial reconstruction, and to describe a novel technique for improving reconstructive skin color match. We hypothesize that split-thickness skin grafts (STSG) placed atop de-epithelialized free tissue produces better facial skin color match than free tissue with intact epithelium.

Study Design: Cross sectional photographic study of reconstructed facial skin color match.

Introduction: Patient-reported outcome measures (PROM) on quality of life (QOL) for early-stage floor of mouth carcinoma (FOM-CA) undergoing surgical resection and split-thickness skin graft (STSG) reconstruction have not been established. We have performed a cross-sectional QOL analysis of such patients to define functional postoperative outcomes.

Methods: Patients with pathologic stage T1/T2 FOM-CA who underwent resection and STSG reconstruction at a tertiary academic cancer center reported outcomes with the University of Washington QOL (v4) questionnaire after at least 6 months since surgery.

Objective/hypothesis: For patients undergoing microvascular free tissue transfer (MFTT), we evaluated risk factors and financial implications of operating room (OR) take-back procedures.

Study Design: Retrospective review at a tertiary care center.

Methods: Patients who underwent MFTT for head and neck reconstruction from 2011 to 2018 were identified.

Objective: For human papilloma virus-associated oropharynx squamous cell carcinoma (HPV+ OPSCC), we evaluated the distribution of neck-level lymph node (LN) metastasis, based on postsurgical histopathology, and the incidence of and risk factors for occult LN metastases, as these patterns need clarification for this newer cancer subset.

Study Design: Retrospective cohort study.

Setting: National Cancer Database (NCDB).

Facial nerve paralysis is an unfortunate, yet relatively common sequela in the treatment of head and neck cancer. Static options for reanimation of the paralyzed midface and oral commissure offer limited quality-of-life improvement and may stretch over time. Reinnervation offers a prolonged recovery and may not be possible among patients with advanced cancer or in salvage situations.

Objectives/hypothesis: For early-stage oral tongue carcinoma and carcinoma in situ (ESOTCCIS), we evaluated patient-reported quality-of-life (QOL) outcomes following resection with primary closure (R-PC).

Study Design: Retrospective review at an academic cancer center.

Methods: Thirty-nine ESOTCCIS patients (Tis, T1, T2) who underwent R-PC without radiation completed the University of Washington Quality of Life Questionnaire Version 4 (UW-QOL) at least 6 months since R-PC (mean = 2.

Aesthetically pleasing and functionally stable total maxillectomy reconstruction is among the greatest of challenges within head and neck surgery. Maintaining presurgical midface projection, contour, and cheek volume requires high-fidelity restorative control incorporating the provision of stable osseous support to prevent the relatively commonplace complications of lower lid and globe malposition. To determine the difference in position of the reconstructed infraorbital rim compared with the contralateral normal side, and its effect on globe position, lower eyelid position, orbital volume, and soft tissue contour.

Objective: Survival outcomes for human papillomavirus-associated oropharynx squamous cell carcinoma (HPV + OPSCC) treated with surgery alone are unclear. To increase understanding, we assessed overall survival (OS) outcomes using the national cancer database (NCDB).

Methods: We conducted a retrospective analysis of OS of 736 NCDB HPV + OPSCC patients who underwent surgery alone from 2010 to 2014 using univariate and multivariate analyses and the Kaplan-Meir method.

This paper describes the information retrieval step in Casama (Contextualized Semantic Maps), a project that summarizes and contextualizes current research papers on driver mutations in non-small cell lung cancer. Casama׳s representation of lung cancer studies aims to capture elements that will assist an end-user in retrieving studies and, importantly, judging their strength. This paper focuses on two types of study metadata: study objective and study design.
