Identifying Patterns of FEES-Derived Swallowing Trajectories Using Group-Based Trajectory Model
Abstract The present study delineates and visualizes swallowing trajectories along seven swallow trials in dysphagic patients using group-based trajectory modeling (GBTM). This model facilitates the recognition of swallowing functional categories, estimates their frequency of occurrence, and enhances the understanding of swallowing dynamics. Two hundred and five dysphagic patients underwent a standardized FEES examination protocol. Five ordinal variables were blindly assessed for each swallow by two observers independently. GBTM analysis was conducted to find and characterize trajectories of FEES responses. For mo...

Swallowing Tablets and Capsules Increases the Risk of Penetration and Aspiration in Patients with Stroke-Induced Dysphagia
Abstract We evaluated the prevalence of difficulties swallowing solid dosage forms in patients with stroke-induced dysphagia and whether swallowing tablets/capsules increases their risk of penetration and aspiration. Concurrently, we explored whether routinely performed assessment tests help identify patients at risk. Using video endoscopy, we evaluated how 52 patients swallowed four different placebos (round, oval, and oblong tablets and a capsule) with texture-modified water (TMW, pudding consistency) and milk and rated their swallowing performance according to the Penetration Aspiration Scale (PAS). Additionall...

The Effect of Bolus Consistency on Hyoid Velocity in Healthy Swallowing
Abstract The aim of this study was to determine whether measures of hyoid velocity increase when swallowing liquids of thicker consistency at a constant volume. A gender-balanced sample of 20 healthy young participants (mean age 31.5) each swallowed 3 boluses of 5 ml volume in 3 consistencies (ultrathin, thin, and nectar-thick barium). Using frame-by-frame tracking of hyoid position, we identified the onset and peak of the hyoid movement and derived measures of velocity (i.e., distance in anatomically normalized units, i.e., % of the C2-4 vertebral distance, divided by duration in ms) for the X, Y, and XY mov...

Rotigotine Transdermal Patch Improves Swallowing in Dysphagic Patients with Parkinson’s Disease
Abstract Abnormal swallowing, dysphagia, is a potentially fatal symptom in Parkinson’s disease (PD) and is characterized by frequent silent aspiration, an unrecognized risk of suffocation and aspiration pneumonia. Several studies have reported that the injection of apomorphine, a dopamine agonist, alleviated dysphagia in some patients with PD. The effects of other antiparkinson medications against dysphagia remain controversial. Rotigotine is another dopamine agonist with non-oral administration, i.e., a transdermal patch. Its noninvasiveness seems to render this medicine even more suitable than apomorphine ...

Penetration–Aspiration: Is Their Detection in FEES ® Reliable Without Video Recording?
Abstract Penetration–aspiration is known as the main finding in deglutition-disordered patients with implications for diagnostics and therapeutic management. Reliable detection of penetration–aspiration is given with fiberoptic endoscopic evaluation of swallowing (FEES®) as one of the gold standards in instrumental swallowing evaluation. The advice to implement video recording in FEES® to assure quality in identifying penetration–aspiration is often ignored, especially in bed-side settings. Thus, the aim of this study was to compare reliability and validity in detecting penetration–...

Electromagnetic Sensor-Guided Enteral Access Systems: A Literature Review
Abstract Enteral feeding is the nutritional support of choice for acutely ill patients with functional gastrointestinal tracts who are unable to swallow. Several benefits including reduced mortality and length of hospital stay have been associated with early initiation of enteral feeding. However, misplacement of conventional nasoenteric tubes is relatively common and can result in complications including pneumothorax. In addition, the need to confirm the position by X-ray can delay the start of using the tube. Eliminating these delays can help patients start feeding, and minimise the adverse impact on initiating ...
