Clinical Trial Summary

The purpose of this research study is to figure out if there are physical factors such as cognition level, nutrition status, walking speed, and handgrip strength that are associated with the development of swallowing problems. Investigators want to better understand how swallowing problems develop in older adults with and without frailty. Identifying factors that contribute to swallowing problems, can develop therapies in the future to improve swallowing outcomes for older adults. This study will be done at the University of Wisconsin-Madison (UW-Madison). A total of about 69 people will participate in this study.

Description:

This study has 3 specific aims: Aim 1 will determine the presence and severity of dysphagia in a cohort of older adults based on clinical frailty phenotype; Aim 2 will examine the effects of frailty status on physiological measures of swallowing in older adults; and Aim 3 will characterize relationships among specific functional frailty domains and dysphagia status in older adults. This proposed research will provide a new understanding of the factors that underlie and contribute to dysphagia across clinical frailty phenotypes. Equipped with this knowledge, future treatment and management approaches can be developed to proactively identify dysphagia risk factors in pre-frail and frail individuals so dysphagia can be prevented or adequately addressed. This work is highly significant due to the large and increasing population of aging people who often suffer from debilitating swallowing impairments and may benefit from optimized treatments that can be developed using knowledge gained from this study. Per approved protocol amendment on 3/39/2022, saliva samples will be collected to explore the composition and structure of oral microbiota via 16S rRNA gene analysis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Summary Composition of buccal, mucosal, and tongue dorsum microbial communities	The composition and structure of the oral microbiota will then be determined via 16S rRNA gene analysis.	2 weeks
Primary	Score on Modified Barium Swallow Impairment Profile (MBSImP)	Dysphagia presence and severity will be examined using the validated Modified Barium Swallow Impairment Profile (MBSImP). Under MBSImP, swallows are assessed via 17 physiologic components pertaining to the oral and pharyngeal phases of swallowing. These individual components are scored from '0' to '5' with higher scores representing greater (worse) impairment within each component. The MBSImP yields total composite scores for the oral and pharyngeal domains as well as an overall impression score which is the worst score across all 17 components.	2 weeks

Secondary	Pharyngeal constriction ratio (PCR)	The 'Pharyngeal Constriction Ratio' (PCR), a pixel-based measure made on lateral view videofluoroscopy swallow study (VFSS) frames. The PCR is calculated by tracing the unobliterated area of the pharynx (including the bolus) at the point of maximum constriction during the swallow and then dividing that area by a corresponding area measure when the pharynx is at rest.	2 weeks
Secondary	Masticatory efficiency evaluated by Test of Masticating and Swallowing Solids (TOMASS)	The Test of Masticating and Swallowing Solids (TOMASS) was developed as a quantitative assessment of solid bolus ingestion. Participants will be instructed to eat a single portion of a cracker "as quickly as is comfortably possible and when you have finished, say your name out loud". Two independent raters will observe a lateral view of the face and count masticatory cycles by observing jaw movements. Timing of the entire task will be recorded using a stopwatch. Longer mastication times/more masticatory cycles required to eat the cracker are a worse outcomes.	2 weeks
Secondary	Number of participants assessed as pass/fail the three ounce water swallow test	Participants will be recorded as "passing" the three ounce water swallow test if they drank the water uninterrupted without coughing, choking, or without presence of a wet/gurgly voice during or immediately after drinking. If a participant stops drinking before finishing the three ounces, has coughing, choking or a wet/gurgly voice during or immediately after drinking, they will be recorded as "failing" this screen.	2 weeks
Secondary	Pharyngeal Pressure Outcome: Integral pressure (mmHg*time)	Integral pressure will be measured in velopharynx, tongue base, hypopharynx. Maximum pressure = the maximum amount of pressure generated at each of these corresponding sensors during the exam.; Duration = the amount of time pressure is generated at each sensor during the trials.; Integral pressure= a summary measure of maximum pressure x time.	2 weeks

Peaks and valleys in each task repetition are amplitude- and time-normalized and aligned with each other. An inbuilt algorithm within the MATLAB program then calculate standard deviations (SDs) across these peak and valley segments at successive 2% intervals, across 50 values per task repetition. The CSTI is then defined as the sum of these SDs with higher CSTI values representing greater pattern variability across the three MAIP trials. Mean CSTI was used in data analysis.	Day 0
