Effects of Thickening Agents on the Mucociliary Transport Function: Comparison by the Type of Thickening Agents and the Viscosity of Thickened Water.

Thickening agents effectively prevent liquid aspiration, but their impact on the ease of discharging aspirated liquids from the trachea remains unclear due to alterations in the physical properties of liquids. This study clarifies the effects of thickening agents, comprising various raw materials, on mucociliary transport function, focusing on the viscosities of thickened waters. The subjects were 23 healthy adults.

The impact of different medical complications on the feasibility of removing the feeding tube from infants with dysphagia.

Purpose: This study examined whether certain medical complications influence the feasibility of tube removal.

Methods: 42 subjects with dysphagia who were under the age of 2.5 years were nourished entirely through feeding tubes.

Comparison of Saccharin Time in Nursing Home Residents With and Without Pneumonia: A Preliminary Study.

Background/aim: Although mucociliary clearance is important for preventing pneumonia, its association with the onset of pneumonia is unclear. The aim of this study is to examine the association between saccharin test results as a potential measure of mucociliary clearance and history of pneumonia in nursing home residents.

Patients And Methods: Ninety elderly nursing home residents (elderly group) were selected, 35 of whom had a history of pneumonia.

The efficacy of nasal airway stent (Nastent) on obstructive sleep apnoea and prediction of treatment outcomes.

Background: Obstructive sleep apnoea (OSA) is characterised by recurrent episodes of partial or complete upper airway collapse during sleep and is highly prevalent in the general population. The nasopharyngeal airway stent (Nastent) is a specifically designed, preformed silicone tube that intends to maintain the upper airway patency during sleep and reduce snoring and sleep apnoea.

Objective(s): The purpose of this study was to determine the efficacy of Nastent treatment and examine predictors for Nastent treatment outcomes in patients with OSA.

Videoendoscopic evaluation of food bolus preparation: A comparison between normal adult dentates and older adult dentates.

Aim: Food bolus preparation plays an important role in swallowing food. The ability to carry out oral functions varies with age, and the same might be true of the ability to prepare food boluses. Previously developed methods for assessing food bolus preparation were not able to evaluate swallowed boluses; that is, the boluses were spat out before they were swallowed.
