The Predictive Value of a Modified Frailty Index on Perioperative Morbidity and Mortality Following Otologic Surgery.

Objectives: Recently, determinants of frailty have become an increasingly recognized perioperative risk stratification tool. This study examines the predictive value of a 5-factor modified frailty index (mFI-5) on perioperative morbidity and mortality in patients undergoing otologic surgery, with a subgroup analysis based on surgery site.

Study Design: Cross-sectional analysis.

Subjective and Objective Taste Change After Stapes Surgery Systematic Review and Meta-Analysis.

Introduction: Iatrogenic injury to the chorda tympani (CT) is a well recognized, although potentially underestimated, consequence of stapes surgery. This study aims to review the currently available literature to determine the incidence and prognosis of taste disturbances in these patients.

Data Sources: PubMed, Embase, and Cochrane Library databases.

Imputation of Below Detection Limit Missing Data in Chemical Mixture Analysis with Bayesian Group Index Regression.

There is growing scientific interest in identifying the multitude of chemical exposures related to human diseases through mixture analysis. In this paper, we address the issue of below detection limit (BDL) missing data in mixture analysis using Bayesian group index regression by treating both regression effects and missing BDL observations as parameters in a model estimated through a Markov chain Monte Carlo algorithm that we refer to as pseudo-Gibbs imputation. We compare this with other Bayesian imputation methods found in the literature (Multiple Imputation by Chained Equations and Sequential Full Bayes imputation) as well as with a non-Bayesian single-imputation method.

Childhood waist growth curves and adult diabetes.

Our primary objectives are to empirically identify distinct childhood groups based on trajectories of waist circumference (WC) and waist circumference index measurements, and then to estimate associations between these groups and adult diabetes incidence, as well as other outcomes, including blood pressure, body size, body composition, and hemoglobin levels. Childhood WC and height measurements as well as various adult measurements are taken from participants in the Fels Longitudinal Study. Childhood groups are identified using group-based trajectory modeling.

Social Media and Academic Impact: Do Early Tweets Correlate with Future Citations?

Objective: This study aims to determine whether social media platforms (SMPs) can influence article impact as measured by citations.

Methods: This is a cross-sectional study that analyzed articles published in the top ten otolaryngology journals by the Eigenfactor score in January 2015. Total accumulated twitter mentions and citations were recorded in 2021.

Bayesian Group Index Regression for Modeling Chemical Mixtures and Cancer Risk.

There has been a growing interest in the literature on multiple environmental risk factors for diseases and an increasing emphasis on assessing multiple environmental exposures simultaneously in epidemiologic studies of cancer. One method used to analyze exposure to multiple chemical exposures is weighted quantile sum (WQS) regression. While WQS regression has been demonstrated to have good sensitivity and specificity when identifying important exposures, it has limitations including a two-step model fitting process that decreases power and model stability and a requirement that all exposures in the weighted index have associations in the same direction with the outcome, which is not realistic when chemicals in different classes have different directions and magnitude of association with a health outcome.

Assessment of Grouped Weighted Quantile Sum Regression for Modeling Chemical Mixtures and Cancer Risk.

Individuals are exposed to a large number of diverse environmental chemicals simultaneously and the evaluation of multiple chemical exposures is important for identifying cancer risk factors. The measurement of a large number of chemicals (the exposome) in epidemiologic studies is allowing for a more comprehensive assessment of cancer risk factors than was done in earlier studies that focused on only a few chemicals. Empirical evidence from epidemiologic studies shows that chemicals from different chemical classes have different magnitudes and directions of association with cancers.

Relationship between pain-related comorbidities and quality of life in patients with symptoms of chronic rhinosinusitis.

Introduction: Facial pain is a common manifestation of sinonasal disease but may be due to a variety of other conditions. Misattribution of pain to chronic rhinosinusitis may result in worse quality of life in populations both with and without objective evidence of sinonasal disease. The purpose of this study was to determine if there is an association between pain-related comorbidities and worse chronic rhinosinusitis specific quality of life in patients with and without objective evidence of sinonasal inflammation.
