“…Second, this was a single-center study. Third, it was necessary to design the study so as to reduce the dropout rate by performing bedside screening tests to determine whether oral feeding was possible before conducting VFSS tests [1819]. Altered vocal production after swallowing has been considered as a leading indicator of inefficient oral feeding, as stasis of food in the laryngeal-pharyngeal cavity during swallowing is commonly observed in patients with dysphagia [18].…”

ObjectiveTo investigate the feasibility of the use of the oropharyngeal airway (OPA) during intermittent oroesophageal tube (IOET) feeding.MethodsTen patients, who were evaluated using the videofluoroscopic swallowing study (VFSS), were enrolled. One patient withdrew from the study during the study period. Tube insertion time with and without OPA use was recorded in the same patients in a random order during the VFSS. Patients who could safely undergo IOET feeding were then randomly allocated to 2 groups (OPA and non-OPA). Satisfaction Questionnaire with Gastrostomy Feeding (SAGA-8) scores and pneumonia incidence were assessed on the 3rd and 10th day after the VFSS. Non-parametric analysis was used for statistical analyses.ResultsThe IOET insertion time was significantly shorter in the OPA group than in the non-OPA group (17.72±5.79 vs. 25.41±10.41 seconds; p=0.017). Complications were not significantly different between the 2 groups (p=0.054). Furthermore, although there were no significant differences in the SAGA-8 scores (25.50±2.38 vs. 21.40±3.13; p=0.066), which reflect the patient/caregiver satisfaction and the ease of tube insertion, patients in the OPA group tended to be more satisfied with the feeding procedure.ConclusionAlthough the small size of the study cohort is a limitation of our study, the use of the OPA appears to be beneficial during IOET feeding in patients with dysphagia.

“…On the other hand, speech–language pathologists widely use the perceptual evaluation of voice quality during clinical swallow examinations because it gives valuable clues regarding swallowing malfunctioning [ 16 , 17 ]. Even though speech production and swallowing are strongly linked at anatomical and physiological levels [ 18 , 19 , 20 ], few studies have addressed this association. Although significant statistical differences have been found between features extracted from speech in healthy individuals and dysphagic patients [ 21 ], the results have not yet been standardized.…”

The swallowing process involves complex muscle coordination mechanisms. When alterations in such mechanisms are produced by neurological conditions or diseases, a swallowing disorder known as dysphagia occurs. The instrumental evaluation of dysphagia is currently performed by invasive and experience-dependent techniques. Otherwise, non-invasive magnetic methods have proven to be suitable for various biomedical applications and might also be applicable for an objective swallowing assessment. In this pilot study, we performed a novel approach for deglutition evaluation based on active magnetic motion sensing with permanent magnet cantilever actuators. During the intake of liquids with different consistency, we recorded magnetic signals of relative movements between a stationary sensor and a body-worn actuator on the cricoid cartilage. Our results indicate the detection capability of swallowing-related movements in terms of a characteristic pattern. Consequently, the proposed technique offers the potential for dysphagia screening and biofeedback-based therapies.

“…[6] Fortunately, there is emerging evidence that early detection of dysphagia reduces not only pulmonary complications but also the duration of hospital stay and overall healthcare cost for acute stroke patients. [7,8] Patients' awareness of their disabilities, including dysphagia after stroke, represents an important aspect of functional recovery. Patients with poor awareness experienced more complications of dysphagia.…”

Background: The assessment of time-trend morbidity and mortality in acute stroke is critical to clinical policy decisions and resource allocation. Objectives: To determine the prevalence of dysphagia in acute stroke and the impact of dysphagia on short term stroke outcome (30 days post-stroke). Methods: This was a prospective longitudinal study. Bedside screening for dysphagia modified Rankin score (MRS) and Barthel Index (BI) were performed on acute stroke patients on day 1, day 7, day 14 and day 30 after stroke to determine the frequency of dysphagia. Patients with dysphagia were then compared with age- and gender-matched controls (stroke patients without dysphagia) in terms of stroke characteristics and 30-day outcome. Results: Of the recruited 200 patients, 99 (49.5%) had dysphagia. Patients with intracerebral haemorrhagic stroke had a significantly higher prevalence of dysphagia (64% vs 36%; p<0.001). At baseline, dysphagic patients had more severe (Mean NHISS score, 22.81 Vs 8.92; p=0.01) and subcortical strokes (57.1% vs 42.9%, p = 0.015). At 30 days after stroke, the mean MRS was significantly higher in the dysphagic stroke patients (3.8±1.02) compared to those without dysphagia (2.5±1.3), (p = 0.001)]. Case fatality was higher among the dysphagic (79.8% vs 15.84%; p = 0.001) and the mean survival time was lower (12.21 days) among the dysphagic group (p = 0.001) Conclusion: Severe stroke, subcortical stroke and haemorrhagic stroke types were significantly associated with dysphagia at baseline. Dysphagia adversely influenced 30-days morbidity and case fatality in this cohort of acute stroke patients.
