Videofluoroscopic Validation of a Translational Murine Model of Presbyphagia
This study provides novel evidence that otherwise healthy aging B6 mice indeed develop age-related changes in swallow function resembling presbyphagia in humans. Specifically, aging B6 mice have a generally slow swallow that spans all stages of swallowing: oral, pharyngeal, and esophageal. The next step is to build upon this foundational work by exploring the responsible mechanisms of presbyphagia in B6 mice. (Source: Dysphagia)

‘Food Sticking in My Throat’: Videofluoroscopic Evaluation of a Common Symptom
Abstract Prevalence of the symptom of food ‘sticking’ during swallowing has been reported to range from 5 to 50 %, depending on the assessment setting. However, limited objective evidence has emerged to clarify factors that contribute to this symptom. Three hundred and fifteen patient records from an outpatient dysphagia clinic were reviewed to identify patients with symptoms of ‘food sticking in the throat.’ Corresponding videofluoroscopic swallowing studies for patients with this complaint were reviewed for the following variables: accuracy of symptom localization, identification and...

Age-Related Changes in Pharyngeal Lumen Size: A Retrospective MRI Analysis
Abstract Age-related loss of muscle bulk and strength (sarcopenia) is often cited as a potential mechanism underlying age-related changes in swallowing. Our goal was to explore this phenomenon in the pharynx, specifically, by measuring pharyngeal wall thickness and pharyngeal lumen area in a sample of young versus older women. MRI scans of the neck were retrospectively reviewed from 60 women equally stratified into three age groups (20s, 60s, 70+). Four de-identified slices were extracted per scan for randomized, blinded analysis: one mid-sagittal and three axial slices were selected at the anterior inferior borde...

The Effect of Prophylactic Percutaneous Endoscopic Gastrostomy (PEG) Tube Placement on Swallowing and Swallow-Related Outcomes in Patients Undergoing Radiotherapy for Head and Neck Cancer: A Systematic Review
Abstract Patients undergoing radiotherapy for head and neck cancer (HNC) often experience malnutrition and dehydration during treatment. As a result, some centres place PEG tubes prophylactically (pPEG) to prevent these negative consequences. However, recent research has suggested that pPEG use may negatively affect swallowing physiology, function and/or quality of life, especially in the long term. The purpose of this study was to systematically review the literature on pPEG use in HNC patients undergoing radiotherapy and to determine its impact on swallowing-related outcomes. The following electronic databases w...

Neural Network Pattern Recognition of Lingual–Palatal Pressure for Automated Detection of Swallow
We describe a novel device and method for real-time measurement of lingual–palatal pressure and automatic identification of the oral transfer phase of deglutition. Clinical measurement of the oral transport phase of swallowing is a complicated process requiring either placement of obstructive sensors or sitting within a fluoroscope or articulograph for recording. Existing detection algorithms distinguish oral events with EMG, sound, and pressure signals from the head and neck, but are imprecise and frequently result in false detection. We placed seven pressure sensors on a molded mouthpiece fitting over the upper tee...

Swallowing Problems at the End of the Palliative Phase: Incidence and Severity in 164 Unsedated Patients
This study suggests that incidence of swallowing problems at the end of the palliative phase is high and that these difficulties may not only result in discomfort for patients, but also can raise concern for caregivers. More information and education on management of swallowing problems in palliative settings might be needed for both relatives and nursing staff. However, the data also suggest that any intervention should be proportional to the level of distress caused by the intervention. (Source: Dysphagia)

Afferent Nerve Ending Density in the Human Laryngeal Mucosa: Potential Implications on Endoscopic Evaluation of Laryngeal Sensitivity
Abstract Laryngeal sensitivity is crucial for maintaining safe swallowing, thus avoiding silent aspiration. The sensitivity test, carried out by fiberoptic endoscopic examination of swallowing, plays an important role in the assessment of dysphagic patients. The ventricular folds appear to be more sensitive than the epiglottis during the sensitivity test. Therefore, this study aimed to investigate the mechanical sensitivity of the supraglottic larynx. In seven healthy adults undergoing microlaryngoscopy to remove vocal cord polyps, we excised mucosal samples from the epiglottis and ventricular folds. We measured a...

Safety and Efficacy of Oral Feeding in Infants with BPD on Nasal CPAP
Abstract Safety and efficacy of oral feeding was examined in infants with bronchopulmonary dysplasia (BPD) on nasal continuous positive airway pressure (NCPAP). We hypothesized that repetitive oral feeding enhances aero-digestive outcomes and reduces resource utilization. Data from infants with BPD (37–42 weeks post menstrual age) that were orally fed while on NCPAP (n = 26) were compared with those that were exclusively gavage fed on NCPAP (n = 27). Subject assignment was random and physician practice based. Specifically, we compared the differences in aero-digestive milestones, res...

The Influence of Food Texture and Liquid Consistency Modification on Swallowing Physiology and Function: A Systematic Review
Abstract Texture modification has become one of the most common forms of intervention for dysphagia, and is widely considered important for promoting safe and efficient swallowing. However, to date, there is no single convention with respect to the terminology used to describe levels of liquid thickening or food texture modification for clinical use. As a first step toward building a common taxonomy, a systematic review was undertaken to identify empirical evidence describing the impact of liquid consistency and food texture on swallowing behavior. A multi-engine search yielded 10,147 non-duplicate articles, which...

The Normative Range for and Age and Gender Effects on the Sydney Swallow Questionnaire (SSQ)
Abstract The Sydney Swallow Questionnaire (SSQ) is a validated measure of the symptomatic severity of oral–pharyngeal dysphagia. Up until now no normative ranges have been established for the questionnaire. This is a limitation in its utility as it makes it difficult to use the tool to identify the prevalence and burden of oral–pharyngeal dysphagia in the general population or within patient populations. The study’s aim was to derive the normative range of dysphagia scores for the SSQ and to determine whether, in nondysphagic individuals, there are any age or gender effects on these scores. The ...

Abstract Yawning is a stereotyped motor behavior characterized by deep inhalation and associated dilation of the respiratory tract, pronounced jaw opening, and facial grimacing. The frequency of spontaneous yawning varies over the diurnal cycle, peaking after waking and before sleep. Yawning can also be elicited by seeing or hearing another yawn, or by thinking about yawning, a phenomenon known as “contagious yawning”. Yawning is mediated by a distributed network of brainstem and supratentorial brain regions, the components of which are shared with other airway behaviors including respiration, swallowi...
