Optimizing the Translational Value of Mouse Models of ALS for Dysphagia Therapeutic Discovery
AbstractThe goal of this study was to compare dysphagia phenotypes in low and high copy number (LCN and HCN) transgenicsuperoxide dismutase 1 (SOD1) mouse models of ALS to accelerate the discovery of novel and effective treatments for dysphagia and early amyotrophic lateral sclerosis (ALS) diagnosis. Clinicopathological features of dysphagia were characterized in individual transgenic mice and age-matched controls utilizing videofluoroscopy in conjunction with postmortem assays of the tongue and hypoglossal nucleus. Quantitative PCR accurately differentiated HCN-SOD1 and LCN-SOD1 mice and nontransgenic controls. All HCN-SO...

Reduced Coordination of Hyolaryngeal Elevation and Bolus Movement in a Pig Model of Preterm Infant Swallowing
In this study, we tested the hypotheses that (1) swallows could beidentified equally well from video of external hyolaryngeal movement and bolus movement in videofluoroscopy, and that (2) the two measures would be tightlytemporally linked in both term and preterm infant pigs. We recorded 222 swallows in simultaneous and precisely synchronized high-speed videofluoroscopy and high-speed camera films of 4 preterm and 3 term infant pigs drinking milk from a bottle. In term pigs, the two measures consistently identified the same swallows in each image stream. However, in preterm pigs there was a high rate of false positives (~ ...

Turkish Version of the Mastication Observation and Evaluation (MOE) Instrument: A Reliability and Validity Study in Children
This study aimed to translate the MOE into Turkish and to test its reliability and validity in children with cerebral palsy (CP). A total of 53 children with CP and 27 typical children were included in the study. The MOE was translated from Dutch into Turkish by using the forward, backward, forward translation method. The internal consistency, intra- and inter-observer reliability, criterion, and discriminant validity of the Turkish version of the MOE (T-MOE) were investigated. Internal consistency was excellent with a Cronbach ’s alpha value of 0.98. The Intraclass correlation coefficient ranged from 0.89 to 0.97 fo...

AbstractThe goal of this study was to further characterize respiratory patterns in total laryngectomees with attention to respiratory-swallow pattern as it relates to presence/absence of tracheoesophageal puncture (TEP) and bolus consistency. It was hypothesized that participants with TEP would exhibit respiratory-swallow patterns that were significantly different than those without TEP and that bolus consistency (thin or solid) would modulate respiratory-swallow pattern. Data were collected from 12 adults (8 male), aged 46 –67 years (mean 57) status post total laryngectomy (1–30 years; average 6 ...

Quality of Life in Treating Persistent Neurogenic Dysphagia with Cricopharyngeal Myotomy
This study analyzed whether quality of life (QoL) is improved after coblation-assisted endoscopic cricopharyngeal myotomy (CAECPM) for patients with persistent neurological dysphagia who meet the criteria by using the Chinese version of the Swallow Quality-of-Life Questionnaire (CSWAL-QOL). 22 patients with dysphagia for more than 6  months after stroke or lateral skull base surgery were screened. All patients exhibited a poor response to conservative treatment such as swallowing rehabilitation. Videofluoroscopic swallowing studies (VFSS) showed a restricted cricopharyngeal opening.

Hypopharyngeal Diverticulum: Toward a Unified Understanding of Its Etiopathogenesis
We report using laser endoscopy to divide the inter-diverticular septum followed by transmucosal cricopharyngeus myotomy. Presentation of a rare, bilobed diverticulum emphasizes the importance of the midline prevertebral raphe in anchoring the pharyngeal constrictor muscl es with respect to the CPM. This lends support to the hypothesis that the etiopathogenesis of ZD is multifactorial while guiding us to a unified understanding of ZD. (Source: Dysphagia)

AbstractA standard for assessing swallowing function after open partial horizontal laryngectomy (OPHL) is still not established. The variability in the measures used to investigate swallowing functional outcomes after OPHL limits the communication among clinicians and the possibility to compare and combine results from different studies.

Objective Assessment of Postoperative Swallowing Difficulty Through Ultrasound in Patients Undergoing Thyroidectomy
AbstractSwallowing discomfort is a common postoperative complaint in patients undergoing thyroidectomy. Contraction of the strap muscles might cause resistance to elevation of the laryngotracheal unit, and downward movement of the laryngotracheal unit may lead to swallowing discomfort. However, few studies have evaluated the mechanism related to limited laryngotracheal elevation after thyroidectomy. We aimed to objectively verify the presence of postoperative impaired laryngotracheal elevation through ultrasound evaluation in patients undergoing thyroidectomy and evaluate its relationship with limitation of laryngotracheal...

Predictors of Residue and Airway Invasion in Parkinson ’s Disease
This study comprehensively examined the pathophysiology underlying dysphagia in people with early to mid-stage PD. The results of the present study indicate that disease severity alone does not predict swallowing changes in PD, and therefore may not be the best factor to identify risk for dysphagia in PD. However, the swallowing kinematics most predictive of residue and the presence of airway invasion were identified. These findings may help to guide the selection of more effective therapy approaches for im proving swallowing safety and efficiency in people with early to mid-stage PD. (Source: Dysphagia)

This study has identified that a large number of tools are currently being used in HNC research to measure swallowing outcomes. The sheer number of tools available to explore dysphagia post HNC highlights the lack of a uniform approach to outcome measurement which limits the potential to compare and combine research studies in order to strengthen treatment evidence. There is a need to develop an international consensus for a core outcome set of swallowing related measures, that capture the holistic impact of dysphagia, for HNC. (Source: Dysphagia)

The Effects of Electrical Stimulation Pulse Duration on Lingual Palatal Pressure Measures During Swallowing in Healthy Older Adults
AbstractLimited research in swallowing physiology has suggested that the most common existing transcutaneous electrical stimulation (TES) protocol (VitalStim) may not penetrate to layers of tissue to affect deep swallowing muscles. TES amplitude is the primary parameter that determines the depth of electrical current penetration (DECP). Preliminary work suggests that replacing a long-pulse duration with a short-pulse duration can increase maximum amplitude tolerance (MAT) within subjects ’ comfort level. Increasing MAT may indicate a higher DECP. The current study evaluates this premise in reference to the effects of...
