A Significant Association of Malnutrition with Dysphagia in Acute Patients
AbstractDysphagia and malnutrition seem to be associated, but little research in detail has been reported. We aimed to clarify the association between dysphagia and malnutrition by adopting accurate diagnosis and mathematical evaluation of dysphagia using videofluorography and nutritional assessment calculated by a well-established nutritional risk index. We conducted a retrospective analysis of 165 enrolled patients who were admitted to our hospital for acute diseases and underwent videofluorography on suspicion of dysphagia in the year 2016. We diagnosed high-risk dysphagia in patients with 8-point penetration –asp...

Lesions Responsible for Delayed Oral Transit Time in Post-stroke Dysphagia
ConclusionDelayed oral phase in post-stroke patients was not negligible clinically. Patients ’ cognitive impairments affect the oral transit time. When adjusting it, we found a trend that the lesion responsible for delayed oral phase was located in the left frontal lobe, though the association did not reach significance. The delay might be related to praxis function. (Source: Dysphagia)

Patient Adherence to Dysphagia Recommendations: A Systematic Review
AbstractPatient adherence to treatment recommendations is an important issue for healthcare providers, in a multitude of specialties, and is critical when assessing the efficacy and effectiveness of a particular treatment approach. Patients who have swallowing impairment often require complex and specific interventions requiring altered daily patterns of behavior. Patients with dysphagia who do not follow recommendations or prescribed exercises may not receive maximum benefit of an intervention. Poor adherence also makes it more difficult to evaluate efficacy of a treatment both clinically and in experimental settings. Fur...

Effectiveness of a New Lead-Shielding Device and Additional Filter for Reducing Staff and Patient Radiation Exposure During Videofluoroscopic Swallowing Study Using a Human Phantom
AbstractInterventional radiology procedures often involve lengthy exposure to fluoroscopy-derived radiation. We therefore devised a videofluoroscopic swallowing study (VFSS) procedure using a human phantom that proved to protect the patient and physician by reducing the radiation dose. We evaluated a new lead-shielding device and separately attached additional filters (1.0-, 2.0-, and 3.0-mm Al filters and a 0.5-mm Cu filter) during VFSS to reduce the patient ’s entrance skin dose (ESD). A monitor attached to the human phantom’s neck measured the ESD. We also developed another lead shield (VFSS Shielding Box, 1...

LVC Timing in Infant Pig Swallowing and the Effect of Safe Swallowing
AbstractRecurrent laryngeal nerve (RLN) injury in neonates, a complication of head and neck surgeries, leads to increased aspiration risk and swallowing dysfunction. The severity of resulting sequelae range from morbidity, such as aspiration pneumonia, to mortality from infection and failure to thrive. The timing of airway protective events including laryngeal vestibule closure (LVC) is implicated in aspiration. We unilaterally transected the RLN in an infant pig model to observe changes in the timing of swallowing kinematics with lesion and aspiration. We recorded swallows using high-speed video-fluoroscopic swallow studi...

The Influence of Oropalatal Dimensions on the Measurement of Tongue Strength
AbstractTongue strength is routinely evaluated in clinical swallowing evaluations since lingual weakness is an established contributor to dysphagia. Tongue strength may be clinically quantified by the maximum isometric tongue pressure (MIP) generated by the tongue against the palate; however, wide ranges in normal performance remain to be fully explained. Although orthodontic theory has long suggested a relation between lingual function and oral cavity dimensions, little attention has been given to the potential influence of oral and palatal structure(s) on healthy variance in MIP generation.

AbstractThe 8-point Penetration-Aspiration Scale (PAS) was introduced to the field of dysphagia in 1996 and has become the standard method used by both clinicians and researchers to describe and measure the severity of airway invasion during swallowing. In this article, we review the properties of the scale and explore what has been learned over 20  years of use regarding the construct validity, ordinality, intervality, score distribution, and sensitivity of the PAS to change. We propose that a categorical revision of the PAS into four levels of increasing physiological severity would be appropriate. The article concl...
