Abstract
PURPOSE Oropharyngeal dysphagia (OD) is one of the possible outcomes in patients hospitalized with COVID-19 and also in the population hospitalized for the treatment of cardiovascular disease. Thus, knowing the predictive risk factors for OD may help with referral and early intervention. This study aimed to verify the association of different factors with OD in hospitalized individuals with cardiovascular disease and COVID-19. METHODS Cross-sectional clinical study approved by the Research Ethics Committee (4,521,771). Clinical evaluation of swallowing was carried out in 72 adult patients with cardiovascular disease and COVID-19 hospitalized from April to September 2020. Individuals under 18 years of age and without previous cardiovascular disease were excluded. The presence of general clinical and/or neurological complications, pronation, stay in the intensive care unit (ICU), orotracheal intubation (OTI), tracheostomy tube, oxygen support and age were considered as predictive risk factors for oropharyngeal dysphagia. Fisher's exact test, Mann Whitney test and logistic regression model were used for analysis. RESULTS General clinical complications (p=0.001), pronation (p=0.003), ICU stay (p=0.043), in addition to the need for oxygen supplementation (p=0.023) and age (p= 0 .037) were statistically significant factors associated. The pronation (0.013) and age (0.038) were independently associated with dysphagia. OTI (p=0.208), tracheostomy (p=0.707) and the presence of previous cerebrovascular accidents (p=0.493) were not statistically significant. CONCLUSION In this study, age and prone position were factors independently associated with oropharyngeal dysphagia, complications such as the need for oxygen supplementation, in addition to the need for ICU admission, were also associated factors in the population.

Abstract
Background Dysphagia is commonly evaluated using videofluoroscopy (VFS). As its ratings are usually subjective normal-abnormal ratings, objective measurements have been developed. We compared the inter-rater reliability of the usual VFS ratings to the objective measurement VFS ratings and evaluated their clinical relevance. Methods Two blinded raters analyzed the subjective normal-abnormal ratings of 77 patients' VFS. Two other blinded raters analyzed the objective measurements of pharyngeal aerated area with bolus held in the oral cavity (PAhold), the pharyngeal area of residual bolus during swallowing (PAmax), the pharyngeal constriction ratio (PCR), the maximum pharyngoesophageal segment opening (PESmax), pharyngoesophageal segment opening duration (POD), airway closure duration (ACD), and total pharyngeal transit time (TPT). We evaluated the inter-rater agreement in the subjective ratings and the objective measurements. Clinical utility analysis compared the measurements with the VFS findings of pharyngeal phase abnormality, penetration/aspiration, and cricopharyngeal relaxation. Results In the pharyngeal findings, the subjective analysis inter-rater agreement was mainly moderate to strong. The strongest agreements were on the pharyngeal residues and penetration/aspiration findings. The objective measurements had fair to good inter-rater agreement. Clinical utility analysis found statistically significant connections between TPT and pharyngeal phase abnormality, normal PCR and lack of penetration/aspiration, and normal PESmax and normal cricopharyngeal relaxation. Conclusions The subjective analysis had moderate to strong inter-rater agreement in the pharyngeal VFS findings, especially concerning pharyngeal residues and penetration/aspiration detection, reflecting the efficacy and safety of swallowing. The objective measurements had fair to good inter-observer reproducibility and could thus improve the reliability of VFS diagnostics. Level of evidence 4.

Abstract
INTRODUCTION Dysphagia is a common and critical consequence of acquired brain injury (ABI) and can cause severe complications. Dysphagia rehabilitation is transforming from mainly compensatory strategies to the retraining of swallowing function using principles from neuroscience. However, there are no studies that map interventions available to retrain swallowing function in patients with moderate-to-severe ABI. OBJECTIVE To systematically map the accessible research literature to answer the research question: Which non-surgical, non-pharmacological interventions are used in the treatment of dysphagia in patients with moderate and severe ABI in the acute and subacute phase? DESIGN: Scoping review based on the methodology of Arksey and O'Malley and methodological advancement by Levac et al. DATA SOURCES: MEDLINE, Embase, Cochrane Library, CINAHL, PsycINFO, Web of Science, OTseeker, speechBITE and PEDro were searched up until 14 March 2021. ELIGIBILITY CRITERIA All studies reporting rehabilitative interventions within 6 months of injury for patients with moderate-to-severe ABI and dysphagia were included. DATA EXTRACTION AND SYNTHESIS Data was extracted by two independent reviewers and studies were categorised based on treatment modality. RESULTS A total of 21 396 records were retrieved, and a final of 26 studies were included. Interventions were categorised into cortical or non-cortical stimulation of the swallowing network. Cortical stimulation interventions were repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation. Non-cortical were complex swallowing interventions, neuromuscular electrical stimulation, pharyngeal electrical stimulation (PES), sensory stimulation, strengthening exercises and respiratory muscle training. CONCLUSION This scoping review provides an overview of rehabilitative dysphagia interventions for patients with moderate and severe ABI, predominantly due to stroke, in the acute and subacute phase. Positive tendencies towards beneficial effects were found for rTMS, complex swallowing interventions, PES and cervical strengthening. Future studies could benefit from clear reporting of patient diagnosis and disease severity, the use of more standardised treatment protocols or algorithms and fewer but standardised outcome measures to enable comparison of effects across studies and interventions.

Abstract
Identification of prognostic factors for swallowing recovery in patients with post-stroke dysphagia is crucial for determining therapeutic strategies. We aimed at exploring hyoid kinematic features of poor swallowing prognosis in patients with post-stroke dysphagia. Of 122 patients who experienced dysphagia following ischemic stroke, 18 with poor prognosis, and 18 age- and sex-matched patients with good prognosis were selected and retrospectively reviewed. Positional data of the hyoid bone during swallowing were obtained from the initial videofluoroscopic swallowing study after stroke onset. Normalized hyoid profiles of displacement/velocity and direction angle were analyzed using functional regression analysis, and maximal or mean values were compared between the good and poor prognosis patient groups. Kinematic analysis showed that maximal horizontal displacement (P = 0.031) and velocity (P = 0.034) in forward hyoid motions were significantly reduced in patients with poor prognosis compared to those with good prognosis. Mean direction angle for the initial swallowing phase was significantly lower in patients with poor prognosis than in those with good prognosis (P = 0.0498). Our study revealed that reduced horizontal forward and altered initial backward motions of the hyoid bone during swallowing can be novel kinematic features indicating poor swallowing prognosis in patients with post-stroke dysphagia.

Abstract
Background and Purpose- The aim of this study was to explore clinical and radiological prognostic factors for long-term swallowing recovery in patients with poststroke dysphagia and to develop and validate a prognostic model using a machine learning algorithm. Methods- Consecutive patients (N=137) with acute ischemic stroke referred for swallowing examinations were retrospectively reviewed. Dysphagia was monitored in the 6 months poststroke period and then analyzed using the Kaplan-Meier method and Cox regression model for clinical and radiological factors. Bayesian network models were developed using potential prognostic factors to classify patients into those with good (no need for tube feeding or diet modification for 6 months) and poor (tube feeding or diet modification for 6 months) recovery of swallowing function. Results- Twenty-four (17.5%) patients showed persistent dysphagia for the first 6 months with a mean duration of 65.6 days. The time duration of poststroke dysphagia significantly differed by tube feeding status, clinical dysphagia scale, sex, severe white matter hyperintensities, and bilateral lesions at the corona radiata, basal ganglia, or internal capsule (CR/BG/IC). Among these factors, tube feeding status (P<0.001), bilateral lesions at CR/BG/IC (P=0.001), and clinical dysphagia scale (P=0.042) were significant prognostic factors in a multivariate analysis using Cox regression models. The tree-augmented network classifier, based on 10 factors (sex, lesions at CR, BG/IC, and insula, laterality, anterolateral territory of the brain stem, bilateral lesions at CR/BG/IC, severe white matter hyperintensities, clinical dysphagia scale, and tube feeding status), performed better than other benchmarking classifiers developed in this study. Conclusions- Initial dysphagia severity and bilateral lesions at CR/BG/IC are revealed to be significant prognostic factors for 6-month swallowing recovery. The prediction of 6-month swallowing recovery was feasible based on clinical and radiological factors using the Bayesian network model. We emphasize the importance of bilateral subcortical lesions as prognostic factors that can be utilized to develop prediction models for long-term swallowing recovery.

Abstract
The subcortex is an important region in terms of swallowing function that passes fibers from the swallowing center to the cortex. However, studies on the relationship between the hemorrhage size and characteristics of dysphagia were lacking. In the present study, the relationship between subcortical hemorrhage size and characteristics of dysphagia was assessed in patients with subcortical hemorrhage. This study recruited retrospectively 49 subcortical hemorrhage patients with dysphagia. The hemorrhage size was measured and the clinical dysphagia scale (CDS) was used to evaluate the severity of dysphagia. The relationship between CDS score and hemorrhage size was analyzed. Subjects were divided into 2 groups according to average hemorrhage size of the subjects. The CDS scores of the 2 groups were compared and the relationship between each CDS item and hemorrhage size was analyzed. A significant positive correlation was observed between hemorrhage size and total CDS score. Also, a significant correlation was observed when patients over 70 years of age were excluded. The total CDS score in the large hemorrhage group was significantly higher than the CDS score in the small hemorrhage group. The CDS items including tracheostomy, lip sealing, tongue protrusion, laryngeal elevation, and reflex coughing were significantly correlated with hemorrhage size. In this study, the hemorrhage size in patients with subcortical hemorrhage correlated with the severity of dysphagia. In addition, the hemorrhage size was correlated with specific CDS items. These findings should be considered when treating subcortical hemorrhage patients with dysphagia in a clinical setting.

Abstract
OBJECTIVES To investigate the characteristics of oropharyngeal dysphagia in adults with dyskinetic cerebral palsy (DCP) and cervical dystonia (CD). DESIGN Exploratory observational cross-sectional study. SETTING University hospital. PARTICIPANTS Seventeen patients with DCP (8 men, 9 women; age, 45.7±6.3y) enrolled in a randomized controlled trial on the effects of botulinum toxin injection on CD. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Baseline clinical assessments and videofluoroscopic swallowing studies (VFSSs) were conducted. VFSS findings were evaluated using the videofluoroscopic dysphagia scale (VDS) and the penetration-aspiration scale (PAS). The Gross Motor Function Classification System (GMFCS) and Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) scores were also assessed. Relationships between outcomes were evaluated using Spearman's rank correlation. RESULTS The clinical assessment revealed abnormalities in chewing (n=10, 58.8%), tongue movement (n=10, 58.8%), and laryngeal elevation (n=8, 47.1%). The most common abnormality on the VDS was inadequate mastication (n=13, 76.5%), followed by premature bolus loss, vallecular residue, and penetration/aspiration (all: n=10, 58.8%). A maximum PAS score of 8 was observed in 8 of 17 patients (47.1%). Total and pharyngeal VDS scores were significantly correlated with TWSTRS scores (ρ=0.543, P=.024 and ρ=0.539, P=.026, respectively); the VDS oral score did not correlate with the TWSTRS score (ρ=0.446, P=.073). There was no significant correlation between VDS score and GMFCS level (ρ=0.212, P=.414). CONCLUSIONS This preliminary observational study presents the characteristics of oropharyngeal dysphagia in adults with DCP and CD. Pharyngeal stage difficulties were negatively correlated with severity of CD, but not with GMFCS level. Screening for dysphagia may be recommended in adults with DCP and severe CD.

Abstract
The videofluoroscopic dysphagia scale (VDS) was developed as an objective predictor of the prognosis of dysphagia after stroke. We evaluated the clinical validity of the VDS for various diseases. We reviewed the medical records of 1,995 dysphagic patients (1,222 men and 773 women) who underwent videofluoroscopic studies in Seoul National University Hospital from April 2002 through December 2009. Their American Speech–Language–Hearing Association’s National Outcome Measurement System (ASHA NOMS) swallowing scale, clinical dysphagia scale (CDS), and VDS scores were evaluated on the basis of the clinical and/or videofluoroscopic findings by the consensus of two physiatrists. The correlations between the VDS and the other scales were calculated. The VDS displayed significant correlations with the ASHA NOMS swallowing scale and the CDS in every disease group (p < 0.001 in all groups, including central and peripheral nervous system disorders), and these correlations were more apparent for spinal cord injury, peripheral nerve system disorders, and neurodegenerative diseases (correlation coefficients between the VDS and the ASHA NOMS swallowing scale: −0.603, −0.602, and −0.567, respectively). This study demonstrated that the VDS is applicable to dysphagic patients with numerous etiologies that cause dysphagia

Abstract
Objective To develop a quantitative and organ-specific practical test for the diagnosis and treatment of dysphagia based on assessment of stroke patients. Methods An initial test composed of 24 items was designed to evaluate the function of the organs involved in swallowing. The grading system of the initial test was based on the analysis of 50 normal adults. The initial test was performed in 52 stroke patients with clinical symptoms of dysphagia. Aspiration was measured via a videofluoroscopic swallowing study (VFSS). The odds ratio was obtained to evaluate the correlation between each item in the initial test and the VFSS. A polychotomous linear logistic model was used to select the final test items. Results Eighteen of 24 initial items were selected as significant for the final tests. These 18 showed high initial validity and reliability. The Spearman correlation coefficient for the total score of the test and functional dysphagia scale was 0.96 (p<0.001), indicating a statistically significant positive correlation. Conclusion This study was carried out to design a quantitative and organ-specific test that assesses the causes of dysphagia in stroke patients; therefore, this test is considered very useful and highly applicable to the diagnosis and treatment of dysphagia.

Abstract
Dysphagia is an important issue in the prognosis of Parkinson's disease (PD). Although several studies have reported that oropharyngeal dysphagia may be associated with cognitive dysfunction, the exact relationship between cortical function and swallowing function in PD patients is unclear. Therefore, we investigated the association between an electrophysiological marker of central cholinergic function, which reflected cognitive function, and swallowing function, as measured by videofluoroscopic studies (VFSS). We enrolled 29 early PD patients. Using the Swallowing Disturbance Questionnaire (SDQ), we divided the enrolled patients into two groups: PD with dysphagia and PD without dysphagia. The videofluoroscopic dysphagia scale (VDS) was applied to explore the nature of the dysphagia. To assess central cholinergic dysfunction, short latency afferent inhibition (SAI) was evaluated. We analyzed the relationship between central cholinergic dysfunction and oropharyngeal dysphagia and investigated the characteristics of the dysphagia. The SAI values were significantly different between the two groups. The comparison of each VFSS component between the PD with dysphagia group and the PD without dysphagia group showed statistical significance for most of the oral phase components and for a single pharyngeal phase component. The total score on the VDS was higher in the PD with dysphagia group than in the PD without dysphagia group. The Mini-Mental State Examination and SAI values showed significant correlations with the total score of the oral phase components. According to binary logistic regression analysis, SAI value independently contributed to the presence of dysphagia in PD patients. Our findings suggest that cholinergic dysfunction is associated with dysphagia in early PD and that an abnormal SAI value is a good biomarker for predicting the risk of dysphagia in PD patients.

Abstract
OBJECTIVES/HYPOTHESIS The aim of this study was to quantitatively investigate spatiotemporal movement abnormalities during the pharyngeal phase of swallowing in individuals with Parkinson's disease (PD) and to investigate relationships between disease and dysphagia severities. STUDY DESIGN Retrospective study. METHODS We performed two-dimensional motion analysis of the hyoid bone, epiglottis, and vocal folds using videofluoroscopic images from 33 PD patients and 33 age-matched, healthy controls. The outcome measures were spatial and temporal movement variables during swallowing. Additionally, three subgroups of patients were compared based on the Hoehn and Yahr scale to identify the relationship between disease and dysphagia severities. RESULTS Individuals with PD showed a reduced anterior hyoid bone displacement after normalization for each individual. The maximal angle of the epiglottic rotation was smaller in PD patients. The time to maximal displacement of the hyoid bone, epiglottis, and vocal folds were significantly delayed in PD patients (P = 0.001, 0.002, and < 0.001, respectively); the mean velocities of the hyoid bone and epiglottic movements were also reduced in PD patients (P < 0.001 and < 0.001, respectively). The velocity curves of the hyoid bone revealed more peaks in individuals with PD, representing incoordination during swallowing. Clinical disease severity was related to level of diet and supervision but not with dysphagia severity. CONCLUSION This study shows that oropharyngeal bradykinesia, incoordination, reduced anterior hyoid bone movement, and decreased epiglottic rotation angle during swallowing are the most noticeable findings in individuals with PD. LEVEL OF EVIDENCE N/A.

Jung SH, Kim J, Jeong H, Lee SU. Effect of the order of test diets on the accuracy and safety of swallowing studies. Ann Rehabil Med 2014; 38:304-9. [PMID: 25024952 PMCID: PMC4092169 DOI: 10.5535/arm.2014.38.3.304] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2014] [Accepted: 04/16/2014] [Indexed: 11/26/2022] Open
Abstract
Objective To assess whether the order of test diets influences the results of swallowing studies with regard to their accuracy and safety. Methods Subjects with suspected dysphagia underwent a videofluoroscopic swallowing study (VFSS) and/or a fiberoptic endoscopic evaluation of swallowing (FEES) and repeated the study on the same day or within a week. The order of test diets comprised of two different sets: trial 1 with the fluid first and trial 2 with the semi-solid food first. Main outcome measurements were the modified penetration-aspiration scale (mPAS) and the pharyngeal residue severity scale (PRSS) for the vallecula and the pyriform sinus. Results Sixty-six patients (44 men and 22 women, aged 65.0±15.0 years) were enrolled in this study. Forty-three subjects were evaluated with VFSS only and 23 with both VFSS and FEES. As a result of the swallowing studies, there was no significant difference in each chosen diet sequence regarding mPAS and PRSS. Furthermore, there was no difference regarding the duration of studies, rate of premature study termination, rate of abnormal findings in post-study chest X-ray, and rate of fever or pneumonia post-study. Conclusion The accuracy and safety of the swallowing studies do not rely on the order of test diets.

Abstract
INTRODUÇÃO: Instrumento eficiente para medição da disfagia, facilmente reprodutível e estatisticamente consistente, deveria fornecer dados mais consistentes sobre os resultados e acompanhamento de doenças com disfagia. As propostas existentes mostram ampla cobertura na avaliação do sintoma disfágico. OBJETIVOS: Analisar as escalas de disfagia disponíveis sugerindo as que permitem avaliação mais objetiva e estatisticamente consistente, e não apenas ferramenta de mensuração, e sugerir as que melhor quantificam o sintoma e úteis para seguimento dos pacientes. MÉTODO: Foram pesquisados os seguintes descritores no Pubmed: "disfagia", "escala", "index", "score". Dez artigos foram selecionados entre 1995 e 2012 com propostas de escalas para a disfagia. RESULTADOS: A maioria das escalas não atingiram os requisitos para serem classificadas como ferramenta completa na avaliação de qualquer disfagia. Muitas são específicas para uma única doença, e poucas com maior abrangência, não têm consistência estatística. Para disfagia orofaríngea (cervical), as escalas FOIS e ASHA são citadas com mais frequência. Na disfagia motora (cervical), a de Zaninotto e Youssef têm aplicabilidade prática, mas ambas necessitam de validação estatística. A de Zaninotto parece ser mais precisa por incluir mais variáveis (disfagia, dor no peito e azia). As escalas que cobrem as duas formas de disfagia (ASHA e DHI) são bem diferentes em seus objetivos. A DHI é escala publicada recentemente examina os dois tipos de disfagia e tem validação estatística bem estruturada. Importante passo no futuro seria testar essa nova proposta com amostra mais expressiva e representativa, provavelmente consagrando esse novo instrumento de avaliação. CONCLUSÃO: As escalas mais frequentes de disfagia relatadas nos últimos 17 anos têm propósito e estruturas diferentes. As escalas FOIS e ASHA são muitas vezes utilizadas para a avaliação da disfagia orofaringeana (região cervical), ambas focadas em terapia nutricional. Para a avaliação motora baixa, a escala de Zaninotto e Youssef tem aplicação prática, e a DHI parece representar a ferramenta mais promissora na avaliação global da disfagia.
