Analysis of Patients' Dietary Status/Restrictions Following Instrumental Swallow Evaluations in Skilled Nursing Facilities.

Many residents in Skilled Nursing Facilities (SNFs) present with dysphagia and receive altered diets or liquids to minimize the risk of complications. Limited access to timely instrumental evaluations of swallow may impede the best management of these dysphagic residents. De-identified FEES reports completed by a mobile FEES company during a single month, January 2019, were reviewed.

Scoring the Penetration-Aspiration Scale (PAS) in Two Conditions: A Reliability Study.

A widely applied metric for identifying airway invasion events is the Penetration-Aspiration Scale (PAS). PAS scores are often included as primary outcome measures in clinical interventional studies, applied to characterize airway protection in a particular disease, used to establish a normal referent for control group comparisons without dysphagia, and as determinants or predictors of clinical outcomes. Despite the widespread use of the PAS, there is variability in scoring condition.

Respiratory-swallow coordination and swallowing impairment in head and neck cancer.

Background: The aim of the study was to determine the link between frequency of optimal respiratory-swallow coordination, swallowing impairment, and airway invasion in head and neck cancer (HNC) patients.

Method: A cross-sectional study of a heterogeneous group of HNC patients (49), precancer (N = 30) or postcancer treatment (N = 29), participated in a single Modified Barium Swallow Study (MBSS) with synchronized respiratory data.

Results: Spearman correlation coefficients revealed significant negative correlations between optimal respiratory-swallow phase pattern and objective measures of swallowing impairment: penetration-aspiration scale max, pharyngeal total, and oral total scores with Spearman correlation coefficients of -0.

Respiratory-Swallow Training Methods: Accuracy of Automated Detection of Swallow Onset, Respiratory Phase, Lung Volume at Swallow Onset, and Real-Time Performance Feedback Tested in Healthy Adults.

Background Preliminary studies have shown that respiratory-swallow training (RST) is a successful treatment for oropharyngeal head and neck cancer patients with refractory dysphagia. Refining the RST protocol with automated analysis software to provide real-time performance feedback has the potential to improve accessibility, reproducibility, and translation to diverse clinical settings. Method An automated software program for data acquisition and analysis developed to detect swallows, determine respiratory phase, calculate lung volume at the onset of the swallow, and provide real-time performance feedback was tested for feasibility in a small cohort of healthy adults.

Respiratory Phase and Lung Volume Patterns During Swallowing in Healthy Adults: A Systematic Review and Meta-Analysis.

Purpose The coordination of respiration with swallowing is critical for facilitation of airway protection and the efficiency of movements that propel ingested material through the upper aerodigestive tract. Confirmation of a predominant pattern in healthy adults provides a platform for comparison to aberrant patterns observed in the population with swallowing impairment (dysphagia). Method A comprehensive search of published research in MEDLINE via PubMed 1946-2018, Embase 1947-2018, and Proquest Dissertations & Theses Global 1861-2018 was completed.

Oropharyngeal swallow physiology and swallowing-related quality of life in underweight patients with concomitant advanced chronic obstructive pulmonary disease.

Background: Swallowing impairment (dysphagia) has been associated with COPD and may contribute to exacerbations of this chronic and progressive disease. Further, risk of mortality increases with concomitant presence of cachexia in the COPD population. The purpose of this prospective study was to depict oropharyngeal swallowing physiology in underweight patients with stable but advanced-stage COPD.
