Prediction of Oral Intake at Discharge with Early Assessment of Swallowing Function within 24 h after Admission: A Retrospective Cohort Study. Dysphagia 2024:10.1007/s00455-024-10699-x. [PMID: 38558178 DOI: 10.1007/s00455-024-10699-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 03/18/2024] [Indexed: 04/04/2024]
Abstract
Dysphagia is one of the most common symptoms of stroke and can lead to other complications such as pneumonia, dehydration, and malnutrition. This retrospective cohort study evaluated the predictive value of a comprehensive swallowing assessment tool, the Mann Assessment of Swallowing Ability (MASA), in the acute phase of stroke for oral intake status at discharge. Among 1,133 consecutive patients with acute stroke, 512 patients whose swallowing function was assessed using the MASA within 24 h of admission were included. Data including demographic information, stroke severity, MASA, Oral Health Assessment Tool, body mass index, and serum albumin level were collected. Predictive factors for oral intake were analyzed using a multiple logistic regression model, and the receiver operating characteristic (ROC) curve analysis was used to determine the cutoff values of the MASA score for determining oral intake at discharge. Oral intake at discharge was established in 69.1% of the cohort (354/512). The multiple logistic regression analysis identified a higher MASA score, younger age, and higher serum albumin level as significant predictors of oral intake at discharge. The cutoff value of the MASA score for oral intake was 136.5 points, with an area under the ROC curve of 0.87. These findings suggest that the MASA is a valid tool for predicting oral intake in patients with dysphagia during the acute phase of stroke.

Use of deep learning to segment bolus during videofluoroscopic swallow studies. Biomed Phys Eng Express 2023; 10:015005. [PMID: 37948874 DOI: 10.1088/2057-1976/ad0bb3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 11/10/2023] [Indexed: 11/12/2023]
Abstract
Anatomical segmentations generated using artificial intelligence (AI) have the potential to significantly improve video fluoroscopic swallow study (VFS) analysis. AI segments allow for various metrics to be determined without additional time constraints streamlining and creating new opportunities for analysis. While the opportunity is vast, it is important to understand the challenges and limitations of the underlying AI task. This work evaluates a bolus segmentation network. The first swallow of thin or liquid bolus from 80 unique patients were manually contoured from bolus first seen in the oral cavity to end of swallow motion. The data was split into a 75/25 training and validation set and a 4-fold cross validation was done. A U-Net architecture along with variations were tested with the dice coefficient as the loss function and overall performance metric. The average validation set resulted in a dice coefficient of 0.67. Additional analysis to characterize the variability of images and performance on sub intervals was conducted indicating high variability among the processes required for training the network. It was found that bolus in the oral cavity consistently degrades performance due to misclassification of teeth and unimportant residue. The dice coefficients dependence on structure size can have substantial effects on the reported value. This work shows the efficacy of bolus segmentation and identifies key areas that are detriments to the performance of the network.

Screening for silent aspiration in hyperacute stroke: A feasibility study of clinical swallowing examination and cough reflex testing. INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2023; 58:1657-1667. [PMID: 37158000 DOI: 10.1111/1460-6984.12893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 03/31/2023] [Indexed: 05/10/2023]
Abstract
BACKGROUND Silent aspiration (SA) is common post-stroke and associated with increased risk of pneumonia, length of stay and healthcare costs. Clinical swallow examinations (CSEs) are unreliable measures of SA. There is no consensus on the clinical components that best detect SA. Cough reflex testing (CRT) is an alternative/adjunct whose SA detection accuracy also lacks consensus. AIMS To investigate the feasibility of CSE versus CRT against gold standard flexible endoscopic evaluation of swallowing (FEES) for SA identification and to estimate its prevalence in a hyperacute stroke setting. METHODS & PROCEDURES A single-arm preliminary, prospective, feasibility study of patients less than 72 h post-stroke, over a 31-day period on a hyperacute stroke unit: the Royal Victoria Infirmary, Newcastle-upon-Tyne, UK. Ethical approval for the study was obtained. The study tested the feasibility and acceptability of introducing CRT and developing a standardized CSE. Consent/assent was obtained for all participants. Patients unfit for study were excluded. OUTCOMES & RESULTS A total of 62% of patients less than 72 h post-stroke (n = 61) were eligible. A total of 75% of those approached (n = 30) consented. A total of 23 patients completed all tests. The principal barrier was anxiety regarding FEES. Mean test time for CRT = 6 min; CSE = 8 min; FEES = 17 min. Patients rated CRT and FEES on average as moderately uncomfortable. A total of 30% (n = 7) of participants who received FEES presented with SA. CONCLUSIONS & IMPLICATIONS CRT, CSE and FEES are feasible in 58% of hyperacute stroke patients in this setting. FEES anxiety is the main recruitment barrier and is not always well tolerated. Results support further work to establish optimum methods and differential sensitivity/specificity of CRT and CSE in hyperacute stroke for SA identification. WHAT THIS PAPER ADDS What is already known on this subject SA significantly increases the risk of pneumonia in the early days post-stroke. CSEs are unreliable for identification of SA risk in this population. CRT is gaining popularity as a potential tool to identify stroke patients at risk of SA, though there are questions regarding the efficacy of the clinical protocol currently being used in the UK. What this study adds to existing knowledge This study demonstrates that it is practical and feasible to carry out a larger scale study in this setting to compare CSE and CRT including a consideration of an approach combining both methods for clinical identification of SA versus FEES. Preliminary findings suggest that CSE may have higher levels of sensitivity than CRT for SA identification. What are the potential or actual clinical implications of this work? The results of this study suggest that further work is needed to establish the optimum methods and differential sensitivity/specificity of clinical tools for SA detection in hyperacute stroke.

Distinctive Gut Microbiota Alteration Is Associated with Poststroke Functional Recovery: Results from a Prospective Cohort Study. Neural Plast 2021; 2021:1469339. [PMID: 34917142 PMCID: PMC8670901 DOI: 10.1155/2021/1469339] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 11/10/2021] [Indexed: 12/14/2022] Open
Abstract
Objectives Functional prognosis is potentially correlated with gut microbiota alterations following the dysregulation of the gut-microbiota-brain axis after stroke. This study was designed to explore the poststroke alterations of gut microbiota and potential correlations between gut microbiota and global functions. Methods A total of thirty-eight patients with stroke and thirty-five healthy demographics-matched controls were recruited. Their fecal DNAs were extracted, and the V3-V4 regions of the conserved bacterial 16S RNA were amplified and sequenced on the Illumina MiSeq platform. Microbial composition, diversity indices, and species cooccurrence were compared between groups. Random forest and receiver operating characteristic analysis were used to identify potential diagnostic biomarkers. Relationships between discriminant bacteria and poststroke functional outcomes were estimated. Results Higher alpha diversity of gut microbiota was observed in poststroke patients as compared to the healthy controls (p < 0.05). Beta diversity showed that microbiota composition in the poststroke group was significantly different from that in the control group. Relative abundance of nine genera increased significantly in poststroke patients, while 82 genera significantly decreased (p < 0.05). The accuracy, specificity, and susceptibility of the optimal model consisted of the top 10 discriminant species were 93%, 100%, and 86%, respectively. Subgroup analysis showed that bacterial taxa abundant between subacute and chronic stroke patients were overall different (p < 0.05). The modified Rankin scale (mRS) (r = −0.370, p < 0.05), Fugl-Meyer assessment (FMA) score (r = 0.364, p < 0.05), water swallow test (WST) (r = 0.340, p < 0.05), and Barthel index (BI) (r = 0.349, p < 0.05) were significantly associated with alterations of distinctive gut microbiota. Conclusions The gut microbiota in patients with stroke was significantly changed in terms of richness and composition. Significant associations were detected between alterations of distinctive gut microbiota and global functional prognosis. It would facilitate novel treatment target selection in the context of stroke while the causal relationships between distinctive gut microbiota alterations and functional variations need to be further verified with well-designed studies.

The role of the Sapienza GLObal Bedside Evaluation of Swallowing after Stroke (GLOBE-3S) in the prevention of stroke-associated pneumonia (SAP). Neurol Sci 2021; 43:1167-1176. [PMID: 34269936 PMCID: PMC8789723 DOI: 10.1007/s10072-021-05449-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 06/28/2021] [Indexed: 11/13/2022]
Abstract
Background and purpose Stroke-associated pneumonia (SAP) affects 10 to 38% of patients in the acute phase of stroke. Stroke patients diagnosed with dysphagia have an 11-fold higher risk of developing SAP. Thus, identifying dysphagic patients through a highly accurate screening tool might be crucial in reducing the incidence of SAP. We present a case–control study designed to evaluate efficacy in reducing the risk of SAP between two swallowing screening tools, the classic water swallow test (WST) and a recently validated tool such as the GLOBE-3S (the Sapienza GLObal Bedside Evaluation of Swallowing after Stroke), which is a highly sensitive swallowing screening tool particularly accurate in detecting silent aspiration as well. Methods We analyzed the occurrence of dysphagia in 100 acute stroke patients distributed in two groups: half were screened with WST and the other half with GLOBE-3S. Results Dysphagia was diagnosed in 28 patients. The main result is that, among patients who passed the dysphagia screenings, none of those screened with the GLOBE-3S method developed pneumonia compared to 31.82% in the WST group. Discriminant function analysis (DFA) showed that NIH Stroke Scale (NIHSS) score and the dysphagia screening method (i.e., GLOBE-3S vs. WST) were the two main factors in the SAP’s predicting model and the only significant ones per se. Conclusions The new GLOBE-3S screening test can reduce the risk of SAP compared to WST.

Swallowing Assessment in Parkinson's Disease: Patient and Investigator Reported Outcome Measures are not Aligned. Dysphagia 2020; 36:864-874. [PMID: 33130951 PMCID: PMC8464560 DOI: 10.1007/s00455-020-10201-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Accepted: 10/19/2020] [Indexed: 10/31/2022]
Abstract
This study determines the relationship between patient and investigator reported outcome measures (PROMs versus IROMs) on oropharyngeal dysphagia (OD) in Parkinson's disease (PD). The PROMs used are the MD Anderson Dysphagia Inventory (MDADI) and the Dysphagia Severity Scale (DSS). The IROMs used are fiberoptic endoscopic evaluation of swallowing (FEES) and videofluoroscopy of swallowing (VFS). Ninety dysphagic PD patients were included. Multilayer perceptron (MLP) neural network analysis was used to investigate the relationship between PROMs and IROMs on OD in PD. MLP neural network analysis showed a moderate agreement between PROMs and IROMs, with an area under the curve between 0.6 and 0.7. Two-step cluster analysis revealed several clusters of patients with similar scores on FEES and/or VFS variables, but with significant different scores on MDADI and DSS variables. This study highlights that there are PD patients with similar FEES and/or VFS findings that cannot be lumped together under the same pathophysiological umbrella due to their differences in PROMs. Since the exact origin of these differences is not fully understood, it seems appropriate for the time being to take into account the different dimensions of OD during the swallowing assessment so that they can be included in a patient-tailored treatment plan.

Development of an Accurate Bedside Swallowing Evaluation Decision Tree Algorithm for Detecting Aspiration in Acute Respiratory Failure Survivors. Chest 2020; 158:1923-1933. [PMID: 32721404 DOI: 10.1016/j.chest.2020.07.051] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Revised: 07/06/2020] [Accepted: 07/12/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND The bedside swallowing evaluation (BSE) is an assessment of swallowing function and airway safety during swallowing. After extubation, the BSE often is used to identify the risk of aspiration in acute respiratory failure (ARF) survivors. RESEARCH QUESTION We conducted a multicenter prospective study of ARF survivors to determine the accuracy of the BSE and to develop a decision tree algorithm to identify aspiration risk. STUDY DESIGN AND METHODS Patients extubated after ≥ 48 hours of mechanical ventilation were eligible. Study procedures included the BSE followed by a gold standard evaluation, the flexible endoscopic evaluation of swallowing (FEES). RESULTS Overall, 213 patients were included in the final analysis. Median time from extubation to BSE was 25 hours (interquartile range, 21-45 hours). The FEES was completed 1 hour after the BSE (interquartile range, 0.5-2 hours). A total of 33% (70/213; 95% CI, 26.6%-39.2%) of patients aspirated on at least one FEES bolus consistency test. Thin liquids were the most commonly aspirated consistency: 27% (54/197; 95% CI, 21%-34%). The BSE detected any aspiration with an accuracy of 52% (95% CI, 45%-58%), a sensitivity of 83% (95% CI, 74%-92%), and negative predictive value (NPV) of 81% (95% CI, 72%-91%). Using recursive partitioning analyses, a five-variable BSE-based decision tree algorithm was developed that improved the detection of aspiration with an accuracy of 81% (95% CI, 75%-87%), sensitivity of 95% (95% CI, 90%-98%), and NPV of 97% (95% CI, 95%-99%). INTERPRETATION The BSE demonstrates variable accuracy to identify patients at high risk for aspiration. Our decision tree algorithm may enhance the BSE and may be used to identify patients at high risk for aspiration, yet requires further validation.

Validity of a dysphagia screening test following resection for head and neck cancer. Ir J Med Sci 2020; 190:67-77. [PMID: 32607911 DOI: 10.1007/s11845-020-02286-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Accepted: 06/18/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND The aim of this study was to evaluate the validity of a dysphagia screening test (DST) in patients who have undergone resection for head and neck cancer (HNC). In addition, we examined whether or not combined effects of DSTs improve the detection accuracy of penetration/aspiration. METHODS Thirty-six HNC patients were participated. The DST consisted of the repetitive saliva swallowing test (RSST), the water swallowing test (WST), the modified water swallowing test (MWST), the food test (FT), and tongue pressure. A videofluoroscopic swallowing study was conducted, and the penetration-aspiration scale was used for scoring. For statistical analyses, we used the receiver operating characteristic (ROC) analysis. Furthermore, the accuracy of the determination of penetration/aspiration was evaluated by combining two or three DSTs. RESULTS The penetration/aspiration could be predicted with moderate accuracy based on MWST and FT. The area under the ROC curve (AUC) values of the MWST and FT were 0.76 (p = 0.03) and 0.80 (p = 0.050), and the sensitivity/specificity was 0.9/0.61 (MWST) and 0.8/0.8 (FT), respectively. As a result of combining 2 or 3 DSTs, the combination of "MWST and FT" was the most accurate, with an AUC of 0.87 (p = 0.02). The combination of three tests had lower accuracy than the combination of two tests. CONCLUSION Based on our results, it is recommended that MWST or FT be used when only one type of DST is performed. In addition, the combination of two DSTs may detect aspiration patients more accurately than one alone.

Abstract
BACKGROUND Older people affected by severe osteoarthritis could need to undergo total joint replacement, with a consequent hospitalization and rehabilitation. In this postacute phase, they might suffer from other symptoms, including dysphagia, defined as a dysfunction of the digestive system, characterized by an objective difficulty or a sensation of difficulty in swallowing. It is considered as a very challenging problem in older people and early detection is fundamental for a prompt and effective management. However, up to date, there is a lack of data on dysphagia risk screening in orthopedic rehabilitation inpatients. AIM The aim of this study was to evaluate dysphagia risk through Eating Assessment Tool (EAT-10) in older people undergoing rehabilitation after total hip or knee arthroplasty. DESIGN Cross-sectional study. SETTING Rehabilitation Unit. POPULATION All consecutive patients undergone total hip or knee arthroplasty, aged ≥65 years, referring to Orthopedics Rehabilitation Unit "Mons. Luigi Novarese" Hospital, Moncrivello, Italy, for a 24-month period (from 1st January 2018 to 31st December 2019). We excluded patients with: 1) diagnosis of neurological diseases; 2) pharyngeal or esophageal cancer; 3) maxillofacial cancer; 4) tracheotomy. METHODS Dysphagia risk was assessed through EAT-10. The cohort was divided into two groups, according to water swallowing test (WST), in order to evaluate differences in terms of different EAT-10 scores. Furthermore, based on pathological WST, we have stratified study participants by the American Speech-Language-Hearing Association (ASHA)'s National Outcomes Measurement System (NOMS) swallowing scale in order to evaluate differences in terms of the different EAT-10 scores. RESULTS We included 534 participants (180 men, 357 women), mean aged 74.8±5.6 years. Thirty-one patients (5.8%) had pathological WST and 34 (6.4%) reported EAT-10 ≥3. There were significant differences (P<0.001) between groups (pathological WST vs. normal WST) in terms of all EAT-10 total scores. EAT-10 reported a high specificity (96.8% if ≥3 and 98.4% if ≥4), but a low sensitivity (58.1% if ≥3 and 54.8% if ≥4). CONCLUSIONS EAT-10 might be considered as useful screening tools for dysphagia in older people, considering the high specificity of EAT-10≥4. CLINICAL REHABILITATION IMPACT Screening dysphagia risk should be recommended also in patients undergoing rehabilitation in order to set up an early diagnosis and management.

Abstract
Zusammenfassung
Hintergrund
Die oropharyngeale Dysphagie ist bei geriatrischen Patienten weit verbreitet und fast immer multikausal bedingt. Sie führt zu schwerwiegenden Komplikationen und wird oft unzureichend detektiert. Alle bekannten und etablierten Screeningmaßnahmen fokussieren sich auf Patienten mit neurologischer Grunderkrankung, insbesondere nach Schlaganfall.
Material und Methoden
In der Arbeitsgruppe „Dysphagie“ der Deutschen Gesellschaft für Geriatrie (DGG), in der Ärzte, Logopäden und Schlucktherapeuten zusammengeschlossenen sind, erfolgte eine selektive Literaturrecherche zum Dysphagiescreening. Basierend auf Ergebnissen der Literaturrecherche und eigenen Erfahrungen wurde durch eine Konsensgruppe ein neues Screeninginstrument für geriatrische Patienten entwickelt und konsentiert.
Ergebnisse
Das Screeninginstrument zur Erfassung einer oropharyngealen Dysphagie bei geriatrischen Patienten gliedert sich in 3 Teile: 1. Vigilanz und Sitzposition, 2. Speichelschluck, Zungenbeweglichkeit und Hustenstoß sowie 3. Wasserschlucktest. Das Screeninginstrument kann durch geschultes medizinisches Personal angewendet werden und ist einfach in den Arbeitsalltag zu integrieren.
Diskussion
Das neu entwickelte Screeninginstrument ist speziell für die Anwendung bei geriatrischen Patienten vorgesehen. Es hat Vorteile gegenüber bisher empfohlenen Screeningtests. Bisherige Erfahrungen zeigen eine gute Praktikabilität und Akzeptanz im geriatrischen Team. Weitere Studien müssen die Validität des Instruments prüfen.

Abstract
BACKGROUND Cough both protects and clears the airway. Cough has three phases: breathing in (inspiration), closure of the glottis, and a forced expiratory effort. Chronic cough has a negative, far-reaching impact on quality of life. Few effective medical treatments for individuals with unexplained (idiopathic/refractory) chronic cough (UCC) are known. For this group, current guidelines advocate the use of gabapentin. Speech and language therapy (SLT) has been considered as a non-pharmacological option for managing UCC without the risks and side effects associated with pharmacological agents, and this review considers the evidence from randomised controlled trials (RCTs) evaluating the effectiveness of SLT in this context. OBJECTIVES To evaluate the effectiveness of speech and language therapy for treatment of people with unexplained (idiopathic/refractory) chronic cough. SEARCH METHODS We searched the Cochrane Airways Trials Register, CENTRAL, MEDLINE, Embase, CINAHL, trials registries, and reference lists of included studies. Our most recent search was 8 February 2019. SELECTION CRITERIA We included RCTs in which participants had a diagnosis of UCC having undergone a full diagnostic workup to exclude an underlying cause, as per published guidelines or local protocols, and where the intervention included speech and language therapy techniques for UCC. DATA COLLECTION AND ANALYSIS Two review authors independently screened the titles and abstracts of 94 records. Two clinical trials, represented in 10 study reports, met our predefined inclusion criteria. Two review authors independently assessed risk of bias for each study and extracted outcome data. We analysed dichotomous data as odds ratios (ORs), and continuous data as mean differences (MDs) or geometric mean differences. We used standard methods recommended by Cochrane. Our primary outcomes were health-related quality of life (HRQoL) and serious adverse events (SAEs). MAIN RESULTS We found two studies involving 162 adults that met our inclusion criteria. Neither of the two studies included children. The duration of treatment and length of sessions varied between studies from four sessions delivered weekly, to four sessions over two months. Similarly, length of sessions varied slightly from one 60-minute session and three 45-minute sessions to four 30-minute sessions. The control interventions were healthy lifestyle advice in both studies.One study contributed HRQoL data, using the Leicester Cough Questionnaire (LCQ), and we judged the quality of the evidence to be low using the GRADE approach. Data were reported as between-group difference from baseline to four weeks (MD 1.53, 95% confidence interval (CI) 0.21 to 2.85; participants = 71), revealing a statistically significant benefit for people receiving a physiotherapy and speech and language therapy intervention (PSALTI) versus control. However, the difference between PSALTI and control was not observed between week four and three months. The same study provided information on SAEs, and there were no SAEs in either the PSALTI or control arms. Using the GRADE approach we judged the quality of evidence for this outcome to be low.Data were also available for our prespecified secondary outcomes. In each case data were provided by only one study, therefore there were no opportunities for aggregation; we judged the quality of this evidence to be low for each outcome. A significant difference favouring therapy was demonstrated for: objective cough counts (ratio for mean coughs per hour on treatment was 59% (95% CI 37% to 95%) relative to control; participants = 71); symptom score (MD 9.80, 95% CI 4.50 to 15.10; participants = 87); and clinical improvement as defined by trialists (OR 48.13, 95% CI 13.53 to 171.25; participants = 87). There was no significant difference between therapy and control regarding subjective measures of cough (MD on visual analogue scale of cough severity: -9.72, 95% CI -20.80 to 1.36; participants = 71) and cough reflex sensitivity (capsaicin concentration to induce five coughs: 1.11 (95% CI 0.80 to 1.54; participants = 49) times higher on treatment than on control). One study reported data on adverse events, and there were no adverse events reported in either the therapy or control arms of the study. AUTHORS' CONCLUSIONS The paucity of data in this review highlights the need for more controlled trial data examining the efficacy of SLT interventions in the management of UCC. Although a large number of studies were found in the initial search as per protocol, we could include only two studies in the review. In addition, this review highlights that endpoints vary between published studies.The improvements in HRQoL (LCQ) and reduction in 24-hour cough frequency seen with the PSALTI intervention were statistically significant but short-lived, with the between-group difference lasting up to four weeks only. Further studies are required to replicate these findings and to investigate the effects of SLT interventions over time. It is clear that SLT interventions vary between studies. Further research is needed to understand which aspects of SLT interventions are most effective in reducing cough (both objective cough frequency and subjective measures of cough) and improving HRQoL. We consider these endpoints to be clinically important. It is also important for future studies to report information on adverse events.Because of the paucity of data, we can draw no robust conclusions regarding the efficacy of SLT interventions for improving outcomes in unexplained chronic cough. Our review identifies the need for further high-quality research, with comparable endpoints to inform robust conclusions.

Abstract
BACKGROUND AND PURPOSE Dysphagia occurs in up to 50% of all patients with acute stroke. There is debate regarding which is the most effective screening tool in identifying aspiration in patients with acute stroke. We assessed the accuracy of the Sapienza Global Bedside Evaluation of Swallowing after Stroke (GLOBE-3S), which combines the Toronto Bedside Swallowing Screening Test (TOR-BSST©) with oxygen desaturation and laryngeal elevation measurement during swallowing. METHODS We prospectively enrolled consecutive patients with stroke within 72 h of symptom onset. All patients with stroke firstly underwent a standard neurological examination, then the GLOBE-3S evaluation and finally the fiberoptic endoscopic evaluation of swallowing (FEES). Two different assessors, a neurologist and a speech pathologist, blind to both the clinical data and each other's evaluation, administered the GLOBE-3S and FEES examination. We assessed the accuracy of the GLOBE-3S in detecting post-stroke swallow impairment with aspiration using the FEES as the standard. RESULTS We enrolled 50 patients with acute stroke, 28 of whom (56%) had swallowing impairment with aspiration at FEES evaluation. A total of 33 patients (66%) failed the GLOBE-3S evaluation. The GLOBE-3S reached a sensitivity of 100% and a specificity of 77.3% (negative predictive value, 100%; positive likelihood ratio, 4.34). The median time required for the GLOBE-3S to be performed was 297 s. CONCLUSIONS GLOBE-3S is quick to perform at the bedside and can accurately identify aspiration in patients with acute stroke. By including the measurement of laryngeal elevation and monitoring of oxygen desaturation, it could represent a highly sensitive instrument to avoid the misdiagnosis of silent aspirators.

The Easy Dysphagia Symptom Questionnaire (EDSQ): a new dysphagia screening questionnaire for the older adults. Eur Geriatr Med 2018; 10:47-52. [PMID: 32720279 DOI: 10.1007/s41999-018-0133-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Accepted: 11/13/2018] [Indexed: 12/13/2022]
Abstract
PURPOSE The early detection of dysphagia, a common clinical issue among older adults, is important. However, healthcare professionals sometimes experience difficulties in applying the current screening tools to older adults. Therefore, we developed the Easy Dysphagia Symptom Questionnaire (EDSQ), a simplified tool for the older adults, and investigated its reliability and validity. METHODS The 12-item "yes/no" EDSQ assesses dysphagia symptoms, with a total score being the sum of all "yes" responses. Each item was determined by consensus of three physiatrists after reviewing the previous dysphagia questionnaires. Participants were aged 65 years or older who either complained of or were suspected by a physician of facing swallowing disturbance. They completed the EDSQ, modified water swallow test (MWST), and videofluoroscopic swallowing study. The EDSQ's internal consistency was assessed. Correlations between the EDSQ total score and the MWST, American Speech-Language-Hearing Association's National Outcome Measurement System (ASHA NOMS) swallowing scale, and videofluoroscopic dysphagia scale (VDS) were analyzed. RESULTS The sample comprised 51 participants (29 male, 56.9%; mean age 76.7 ± 6.6 years). Mean EDSQ total score was 4.33 ± 3.03 (range 0-12). Regarding the EDSQ's reliability, the Cronbach's α coefficient was 0.785. The EDSQ total score correlated with the MWST (r = - 0.468, p = 0.001), ASHA NOMS swallowing scale (r = - 0.635, p < 0.001), and VDS (r = 0.449, p = 0.001). The receiver-operating characteristic analysis revealed an optimal cut-off score of ≥ 5, with a sensitivity of 90.9% and a specificity of 67.5%. CONCLUSIONS The EDSQ showed acceptable reliability and validity, indicating its applicability to older adults as a simple screening tool for safe swallowing.

Abstract
BACKGROUND AND PURPOSE The presence of dysphagia and aspiration in stroke patients is associated with increased mortality and morbidity. Early recognition and management of these two conditions via reliable, minimally invasive bedside procedures before complications arise remains challenging in everyday clinical practice. This study reviews the available bedside screening tools for detecting swallowing status and aspiration risk in acute stroke by qualitatively observing reference population study design, clinical flexibility, reliability and applicability to acute-care settings. METHODS The primary search was conducted using the PubMed, Embase, and Cochrane Library databases. The search was limited to papers on humans written in English and published from 1991 to 2016. Eligibility criteria included the consecutive enrollment of acute-stroke inpatients and the development of a protocol for screening aspiration risk during oral feeding in this population. RESULTS Of the 652 sources identified, 75 articles were reviewed in full however, only 12 fulfilled the selection criteria. Notable deficiencies in most of the bedside screening protocols included poor methodological designs and inadequate predictive values for aspiration risk which render clinicians to be more conservative in making dietary recommendations. CONCLUSIONS The literature is dense with screening methods for assessing the presence of dysphagia but with low predictive value for aspiration risk after acute stroke. A standard, practical, and cost-effective screening tool that can be applied at the bedside and interpreted by a wide range of hospital personnel remains to be developed. This need is highlighted in settings where neither trained personnel in evaluating dysphagia nor clinical instrumentation procedures are available.

Abstract
BACKGROUND Early detection of dysphagia is critical to reducing hospital complications and length of stay in patients with various types of strokes. The aim of this study was to develop and evaluate the DePaul Hospital Swallow Screener (DHSS) tool to assess for dysphagia in patients with stroke. METHODS This prospective observational study investigated patients admitted to a comprehensive stroke center. The DHSS is composed of a questionnaire containing 8 nonswallow items and a water swallow test. All patients admitted under a standard stroke protocol are screened by the nursing staff using the DHSS and then objectively evaluated by a speech-language pathologist using the Mann Assessment of Swallowing Ability (MASA). Validity measures and reliability through Cohen's κ-coefficient with associated 95% confidence intervals were calculated. RESULTS A total of 224 patients completed the DHSS and had at least 1 MASA score. The overall Content Validity Index score for the DHSS was .92. Compared with the MASA dysphagia cutoff value, the DHSS had a specificity of 93% and a sensitivity of 69%, and compared with the MASA aspiration risk cutoff value, the DHSS had a specificity of 90% and a sensitivity of 70%. Stratified analysis for those with any documented stroke (ischemic or hemorrhagic) compared with those admitted with transient ischemic attack or no stroke yielded similar sensitivity and specificity in both dysphagia and aspiration risk. CONCLUSION The DHSS is a valid and reliable swallow screening tool with moderate agreement, high specificity, and reliable predictive values when compared with the MASA.

Abstract
PURPOSE OF REVIEW The article reviews recent literature supporting the use of cough reflex testing (CRT), and outlines a service evaluation of CRT conducted with postsurgical head and neck cancer patients. There is a growing evidence base to support the use of CRT in dysphagia management to establish laryngeal sensation and screen for silent aspiration; however, there is a lack of evidence relating to using CRT within the head and neck population. RECENT FINDINGS Over a 3-month period, inpatients on an ear, nose and throat/maxillofacial ward underwent CRT as part of their clinical swallow evaluation. Data from these patients were collected, including their diagnoses, CRT findings, and subsequent management. The evaluation was limited by difficulties in maintaining a supply of citric acid, accessing medics to prescribe the citric acid, and staffing levels, as administration of the CRT initially required two members of staff to be present. SUMMARY The service evaluation findings, alongside current evidence examining noncancer mortality rates, suggests identification of silent aspiration is important in this population. CRT was useful to rationalize instrumental assessments and was easily incorporated into the swallowing evaluation. More evidence is needed to support the use of CRT within the head and neck population.

Abstract
OBJECTIVES To compare the videofluoroscopic findings of patients with suspected oropharyngeal dysphagia with the results of a clinical screening protocol. METHODS A retrospective observational cohort study was conducted on all consecutive patients with suspected oropharyngeal dysphagia between March 2015 and February 2016 who were assigned to receive a videofluoroscopic assessment of swallowing. All patients were first submitted to videofluoroscopy and then to the clinical assessment of swallowing. The clinical assessment was performed within the first 24 hours after videofluoroscopy. The videofluoroscopy results were analyzed regarding penetration/aspiration using an 8-point multidimensional perceptual scale. The accuracy of the clinical protocol was analyzed using the sensitivity, specificity, likelihood ratios and predictive values. RESULTS The selected sample consisted of 50 patients. The clinical protocol presented a sensitivity of 50% and specificity of 95%, with an accuracy of 88%. "Cough" and "wet-hoarse" vocal quality after/during swallowing were clinical indicators that appeared to correctly identify the presence of penetration/aspiration risk. CONCLUSION The clinical protocol used in the present study is a simple, rapid and reliable clinical assessment. Despite the absence of a completely satisfactory result, especially in terms of the sensitivity and positive predictive values, we suggest that lower rates of pneumonia can be achieved using a formal dysphagia screening method.

Abstract
Within the context of screening tests, it is important to avoid misconceptions about sensitivity, specificity, and predictive values. In this article, therefore, foundations are first established concerning these metrics along with the first of several aspects of pliability that should be recognized in relation to those metrics. Clarification is then provided about the definitions of sensitivity, specificity, and predictive values and why researchers and clinicians can misunderstand and misrepresent them. Arguments are made that sensitivity and specificity should usually be applied only in the context of describing a screening test’s attributes relative to a reference standard; that predictive values are more appropriate and informative in actual screening contexts, but that sensitivity and specificity can be used for screening decisions about individual people if they are extremely high; that predictive values need not always be high and might be used to advantage by adjusting the sensitivity and specificity of screening tests; that, in screening contexts, researchers should provide information about all four metrics and how they were derived; and that, where necessary, consumers of health research should have the skills to interpret those metrics effectively for maximum benefit to clients and the healthcare system.

Abstract
Background Dysphagia is a frequent and dangerous complication of acute stroke. Apart from a well-timed oropharyngeal muscular contraction pattern, sensory feedback is of utmost importance for safe and efficient swallowing. In the present study, we therefore analyzed the relation between pharyngolaryngeal sensory deficits and post-stroke dysphagia (PSD) severity in a cohort of acute stroke patients with middle cerebral artery (MCA) infarction. Methods Eighty-four first-ever MCA stroke patients (41 left, 43 right) were included in this trial. In all patients, fiberoptic endoscopic evaluation of swallowing (FEES) was performed according to a standardized protocol within 96 h after stroke onset. PSD was classified according to the 6-point fiberoptic endoscopic dysphagia severity scale. Pharyngolaryngeal sensation was semi-quantitatively evaluated by a FEES-based touch technique. Results PSD severity was closely related to the pharyngolaryngeal sensory deficit. With regards to lateralization of the sensory deficit, there was a slight but significant preponderance of sensory loss contralateral to the side of stroke. Apart from that, right hemispheric stroke patients were found to present with a more severe PSD. Conclusions This study provides evidence that an intact sensory feedback is of utmost importance to perform nonimpaired swallowing and highlights the key role of disturbed pharyngeal and laryngeal afferents in the pathophysiology of PSD.

Abstract
This chapter describes the nutritional aspects of dysphagia management by starting with the definition of these two conditions (dysphagia and malnutrition) that share three main clinical characteristics: (a) their prevalence is very high, (b) they can lead to severe complications, and (c) they are frequently underrecognized and neglected conditions. From an anatomical standpoint, dysphagia can result from oropharyngeal and/or esophageal causes; from a pathophysiological perspective, dysphagia can be caused by organic or structural diseases (either benign or malignant) or diseases causing impaired physiology (mainly motility and/or perception disorders). This chapter gathers up-to-date information on the screening and diagnosis of oropharyngeal dysphagia, the consequences of dysphagia (aspiration pneumonia, malnutrition, and dehydration), and on the nutritional management of dysphagic patients. Concerning this last topic, this chapter reviews the rheological aspects of swallowing and dysphagia (including shear and elongational flows) and its influence on the characteristics of the enteral nutrition for dysphagia management (solid/semisolid foods and thickened liquids; ready-to-use oral nutritional supplements and thickening powders), with special focus on the real characteristics of the bolus after mixing with human saliva.

Abstract
OBJECTIVE The purpose of this study was to characterize the swallowing sound and identify the process of sound generation during swallowing in young healthy adults. METHODS Thirty-three healthy volunteers were enrolled and allocated into three experimental groups. In experiment 1, a microphone was attached to one of eight cervical sites in 20 subjects, participants swallowed 5 ml water, and the sound waveform was recorded. In experiment 2, 10 subjects swallowed either 0, 5, 10, or 15 ml water during audio recording. In addition, participants consumed the 5 ml bolus in two different cervical postures. In experiment 3, the sound waveform and videofluoroscopy were simultaneously recorded while the three participants consumed 5 ml iopamidol solution. The duration and peak intensity ratio of the waveform were analyzed in all experimental groups. RESULTS The acoustic analysis of the waveforms and videofluoroscopy suggested that the swallowing sound could be divided into three periods, each associated with a stage of the swallowing movement: the oral phase comprising posterior tongue and hyoid bone movement; the pharyngeal phase comprising larynx movement, hyoid bone elevation, epiglottis closure, and passage of the bolus through the esophagus orifice; and the repositioning phase comprising the return of the hyoid bone and larynx to their resting positions, and reopening of the epiglottis. CONCLUSION Acoustic analysis of swallowing sounds and videofluoroscopy suggests that the swallowing sound could be divided into three periods associated with each process of the swallowing movement: the oral phase comprising the posterior movement of the tongue and hyoid bone; the pharyngeal phase comprising the laryngeal movement, hyoid bone elevation, epiglottis closure, and the bolus passage to the esophagus orifice; and the repositioning phase comprising the repositioning of the hyoid bone and larynx, and reopening of the epiglottis.

Abstract
BACKGROUND Stroke is the leading cause of mortality and disability worldwide. Important sequels are frequent, including dysphagia and communication disorders. OBJECTIVE to determine the prevalence of dysphagia and communication disorders following stroke, and to identify if communication disorders can predict dysphagia. METHODS Thirty-one prospective and consecutive patients were admitted to the Otolaryngology-Dysphagia Outpatient Clinic with diagnosis of ischemic or hemorrhagic stroke. Stroke was confirmed by computed tomography or magnetic resonance imaging, and medical evaluation. All patients had a swallowing and communication evaluation. We compared patients with and without dysphagia, and established the co-occurrence among dysphagia and communication disorders. RESULTS Twenty-five patients presented dysphagia. Aphasia occurred in 32.3% of the patients; dysarthria in 45.2%. Dysphagia and aphasia co-occurred in 29% of the population; dysphagia and dysarthria in 45.2%; the three conditions co-occurred in 22.6%. Dysarthria was a predictor of dysphagia, and it was associated with the presence of oral stage problems. CONCLUSIONS A comprehensive evaluation of dysphagia, aphasia, and dysarthria are important to improve clinical outcome following stroke. The identification of dysarthria as a predictor of dysphagia can help identify risk for dysphagia in stroke and assist in the therapeutic process of swallowing problems.

Abstract
This position document has been developed by the Dysphagia Working Group, a committee of members from the European Society for Swallowing Disorders and the European Union Geriatric Medicine Society, and invited experts. It consists of 12 sections that cover all aspects of clinical management of oropharyngeal dysphagia (OD) related to geriatric medicine and discusses prevalence, quality of life, and legal and ethical issues, as well as health economics and social burden. OD constitutes impaired or uncomfortable transit of food or liquids from the oral cavity to the esophagus, and it is included in the World Health Organization's classification of diseases. It can cause severe complications such as malnutrition, dehydration, respiratory infections, aspiration pneumonia, and increased readmissions, institutionalization, and morbimortality. OD is a prevalent and serious problem among all phenotypes of older patients as oropharyngeal swallow response is impaired in older people and can cause aspiration. Despite its prevalence and severity, OD is still underdiagnosed and untreated in many medical centers. There are several validated clinical and instrumental methods (videofluoroscopy and fiberoptic endoscopic evaluation of swallowing) to diagnose OD, and treatment is mainly based on compensatory measures, although new treatments to stimulate the oropharyngeal swallow response are under research. OD matches the definition of a geriatric syndrome as it is highly prevalent among older people, is caused by multiple factors, is associated with several comorbidities and poor prognosis, and needs a multidimensional approach to be treated. OD should be given more importance and attention and thus be included in all standard screening protocols, treated, and regularly monitored to prevent its main complications. More research is needed to develop and standardize new treatments and management protocols for older patients with OD, which is a challenging mission for our societies.

Abstract
Communication and swallowing disorders are common after stroke. Targeted surveillance followed by prompt evaluation and treatment is of paramount importance. The overall goals of rehabilitation for impaired swallowing and communication and swallowing deficits may differ based on the specific deficits caused by the stroke but the main goal is always to improve the patient's everyday interpersonal interactions and optimize participation in society. Fortunately, therapeutic or compensatory interventions can decrease the effects that communication and swallowing deficits have on the quality of life of stroke survivors.

Abstract
AIM The aim of this study was to determine the diagnostic accuracy of the water swallow test for screening aspirations in stroke patients. BACKGROUND The water swallow test is a simple bedside screening tool for aspiration among stroke patients in nursing practice, but results from different studies have not been combined before. DESIGN A systematic review and meta-analysis was conducted to provide a synthetic and critical appraisal of the included studies. DATA SOURCES Electronic literature in MEDLINE, EMBASE, CINAHL and other sources were searched systemically in this study. Databases and registers were searched from inception up to 30 April 2015. REVIEW METHODS This systematic review was conducted using the recommendations from Cochrane Collaboration for Systematic Reviews of Diagnostic Test Accuracy. Bivariate random-effects models were used to estimate the diagnostic accuracy across those studies. The tool named Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) was used to evaluate the quality of the studies. RESULTS There were 770 stroke patients in the 11 studies for the meta-analysis. The water swallow test had sensitivities between 64-79% and specificities between 61-81%. Meta-regression analysis indicated that increasing water volume resulted in higher sensitivity but lower specificity of the water swallow test. CONCLUSIONS This systematic review showed that the water swallow test was a useful screening tool for aspiration among stroke patients. The test accuracy was related to the water volume and a 3-oz water swallow test was recommended for aspiration screening in stroke patients.

Abstract
BACKGROUND Hospitalizations for aspiration pneumonia have doubled among older adults. Using a bedside water swallow test (WST) to screen for swallowing-related aspiration can be efficient and cost-effective for preventing additional comorbidities and mortality. We evaluated screening accuracy of bedside WSTs used to identify patients at risk for dysphagia-associated aspiration. METHODS Sixteen online databases, Google Scholar, and known content experts through May 2015 were searched. Only prospective studies with patients ≥ 18 years of age given WST screenings validated against nasoendoscopy or videofluoroscopy were included. Data extraction used dual masked extraction and quality assessment following Meta-analysis of Observational Studies in Epidemiology guidelines. RESULTS Airway response (eg, coughing/choking) with or without voice changes (eg, wet/gurgly voice quality) was used to identify aspiration during three different bedside WSTs. Pooled estimates for single sip volumes (1-5 mL) were 71% sensitive (95% CI, 63%-78%) and 90% specific (95% CI, 86%-93%). Consecutive sips of 90 to 100 mL trials were 91% sensitive (95% CI, 89%-93%) and 53% specific (95% CI, 51%-55%). Trials of progressively increasing volumes of water were 86% sensitive (95% CI, 76%-93%) and 65% specific (95% CI, 57%-73%). Airway response with voice change improved overall accuracy in identifying aspiration. CONCLUSIONS Currently used bedside WSTs offer sufficient, although not ideal, utility in screening for aspiration. Consecutive sips with large volumes in patients who did not present with overt airway responses or voice changes appropriately ruled out risk of aspiration. Small volumes with single sips appropriately ruled in aspiration when clinical signs were present. Combining these bedside approaches may offer improved screening accuracy, but further research is warranted.

Abstract
BACKGROUND AND OBJECTIVES The Eating Assessment Tool (EAT-10) is a 10-item self-administered questionnaire. It is a noninvasive tool to measure patients' perception of their swallowing problems. The purposes of the present study were to develop an Arabic version of the EAT-10 and to evaluate its validity, consistency, and reliability in the Arabic-speaking population with oropharyngeal dysphagia. SETTING AND DESIGN This was a prospective study carried out at the Communication and Swallowing Disorders Unit, King Saud University, Riyadh, Saudi Arabia. SUBJECTS AND METHODS The Arabic EAT-10 was administered to 138 patients with oropharyngeal dysphagia and 83 control subjects. Internal consistency and test-retest reliability were evaluated. Content and clinical validity were studied, and the EAT-10 results were compared across patients and control groups. RESULTS The Arabic EAT-10 showed excellent internal consistency (Cronbach's α = 0.92). Also, good test-retest reliability was found for the total scores of the Arabic EAT-10 (intraclass correlation = 0.73). There was a significant difference in Arabic EAT-10 scores between the oropharyngeal dysphagia group and the control group (p < 0.001). CONCLUSION This study demonstrated that the Arabic EAT-10 is a valid tool that can be used for screening of dysphagia-related problems in an Arabic-speaking population.

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
Swallowing disorders are frequent. The main concern is mortality due to aspiration-induced pneumonia and malnutrition. In addition, quality of life is severely affected. The demographic trend indicates an increase of dysphagia in the future. Neurodegenerative diseases, tumors of the digestive tract, and sequelae of tumor treatment in the head and neck region are the main pathologic entities. Predominantly ENT physicians and phoniatricians are asked for diagnostics and therapy, and will coordinate the interdisciplinary treatment according to the endoscopic findings. A differentiated approach in history, diagnostics, and symptom-oriented treatment is necessary for these mostly complex disorders. Integration of non-medical staff such as speech therapists, physiotherapists, and occupational therapists in planning and executing an effective therapy expands and completes the patient-oriented care. Conservative treatment by these therapists is an important pillar in the treatment. Parts of the specific diagnostics can be taken over in close cooperation. In particular, an interdisciplinary cooperation with the staff of intensive care medicine is essential. The diagnostic procedures of specific endoscopy as described in this position paper are part of the primary and fundamental tasks of ENT specialists and phoniatrists. Endoscopy is a medical service that is basically not delegable. Consequently, substitution of the physician is excluded.

Abstract
Resumo:OBJETIVO:identificar critérios clínicos utilizados por profissionais para liberação de alimentação via oral em pacientes hospitalizados que apresentam risco para disfagia.MÉTODOS:participaram do estudo 48 profissionais que atuam em dois hospitais gerais de uma cidade do interior do Paraná. Os dados foram coletados por meio da aplicação de um questionário.RESULTADOS:100% dos profissionais consideram o nível de consciência importante para a deglutição, apenas 52,2% vê a importância da presença de deglutição salivar antes que se inicie via oral. Destes, 95,8% elencam Acidente vascular cerebral e Traumatismo cranioencefálico como principais doenças relacionadas a disfagia, porém nenhum apontou a Doença Pulmonar Obstrutiva Crônica. Além disso, somente 47,9% reconhecem a importância da avaliação fonoaudiológica após extubação orotraqueal independente do motivo da intubação ou patologia de base. E, 45,8% considera necessária oclusão do orifício da traqueostomia no momento da oferta alimentar, mostrando que não fazem a relação entre fisiologia da deglutição e uso da traqueostomia. Sobre alimentar um paciente com cânula plástica e balonete insuflado, 52,1% dos profissionais consideram ser possível e 47,9% dizem que não. Observa-se que 77,1% dos profissionais considera que a retirada da traqueostomia melhora e facilita o processo de deglutição, sendo este um percentual estatisticamente significante.CONCLUSÃO:há um conhecimento regular dos profissionais sobre o manejo das disfagias em âmbito hospitalar. Verifica-se a necessidade de um programa de formação continuada a equipe para melhoria do atendimento de pacientes disfágicos.

Abstract
BACKGROUND The requirement for otorhinolaryngologists and phoniatricians to diagnose dysphagia and evaluate its extent is on the rise, particularly in light of demographic changes. The gold standards in confirmatory diagnostics are fiberoptic endoscopic evaluation of swallowing (FEES) and the videofluoroscopic swallowing examination (VFS). Standardized assessments, such as questionnaires or assessments involving probatory swallows are often applied as screening or supportive measures. This article aims to give a critical overview of the assessment tools frequently used in clinical routine. Test quality is assessed, particularly compared to FEES and VFS. METHODS A selective literature search using PubMed has been conducted. RESULTS On the basis of this lierature search, 48 assessment tools were identified. These can be classified into screening tools, instrument-based tools (implementation standards and evaluation protocols) and questionnaire-based assessment inventories. DISCUSSION In order to diagnose and evaluate dysphagia on the basis of assessment critieria, clinicians should be aware of indications for, as well as the advantages, disadvantages and test quality of the assessment tools. Considering the different assessment tools for anamnesis and probatory swallowing, rather low sensitivities and specificities for possible penetration and aspiration are evident. In cases where these symptoms of dysphagia are not evident and reliably assessable, confirmatory assessment via FEES or VFS is essential.

Abstract
The aim of this study was to identify the correlation between the Mann Assessment of Swallowing Ability (MASA) and the Videofluoroscopic Dysphagia Scale (VDS) to investigate the applicability of the MASA as a follow-up test of swallowing function. Criterion validity was assessed for MASA results versus VDS scores of tests administered to 54 patients who had a stroke and dysphagia. A significant correlation was found between the MASA and the VDS (correlation coefficient = -0.509). In analyses of test-re-test reliability and inter-rater reliability of the scoring scale, intraclass correlation coefficients (2, 1) were high (0.98, 0.99). In conclusion, the results of the present study indicate that the MASA holds adequate clinical test-re-test and inter-rater reliabilities and criterion validity for measuring the swallowing abilities of Korean patients who had a stroke and dysphagia. The MASA could contribute to more systematic management of swallowing problems and efficient therapeutic service.

Abstract
We evaluated the reliability of ultrasound evaluation of hyoid-larynx approximation with positional change. Twenty healthy volunteers (10 men, 10 women) participated in this study. The distance between the hyoid bone and thyroid cartilage was measured by ultrasound in both the sitting and supine positions. Hyoid-larynx approximation was defined as the shortest distance between the lower tip of the hyoid bone and the upper end of the thyroid cartilage during swallowing. The transducer was placed in a longitudinal position above the midline of the larynx, which allowed visualization of the hyoid bone and thyroid cartilage. Patients were given 5 mL of water and swallowed. The measurement was repeated three times to enable averaging in each position. Using the mean distance at rest and the shortest distance during swallowing, we calculated relative laryngeal elevation. There was no significant difference in resting distance between the hyoid bone and thyroid cartilage with positional change or gender, with identical relative laryngeal elevation. However, there was a negative correlation between the resting and approximation distance and body mass index. In conclusion, ultrasound evaluation in healthy volunteers revealed no difference in hyoid-laryngeal approximation on swallowing in either the supine or sitting position. This finding is likely to be of value in the investigation of dysphagia.

Abstract
Dysphagia is associated with aspiration, pneumonia, and malnutrition, but remains challenging to identify at the bedside. A variety of exam protocols and maneuvers are commonly used, but the efficacy of these maneuvers is highly variable. We conducted a comprehensive search of 7 databases, including MEDLINE, Embase, and Scopus, from each database's earliest inception through June 9, 2014. Studies reporting diagnostic performance of a bedside examination maneuver compared to a reference gold standard (videofluoroscopic swallow study or flexible endoscopic evaluation of swallowing with sensory testing) were included for analysis. From each study, data were abstracted based on the type of diagnostic method and reference standard study population and inclusion/exclusion characteristics, design, and prediction of aspiration. The search strategy identified 38 articles meeting inclusion criteria. Overall, most bedside examinations lacked sufficient sensitivity to be used for screening purposes across all patient populations examined. Individual studies found dysphonia assessments, abnormal pharyngeal sensation assessments, dual axis accelerometry, and 1 description of water swallow testing to be sensitive tools, but none were reported as consistently sensitive. A preponderance of identified studies was in poststroke adults, limiting the generalizability of results. No bedside screening protocol has been shown to provide adequate predictive value for presence of aspiration. Several individual exam maneuvers demonstrated reasonable sensitivity, but reproducibility and consistency of these protocols was not established. More research is needed to design an optimal protocol for dysphagia detection.

Abstract
OBJECTIVE To assess the effect of adding acupuncture to standard swallowing training for patients with dysphagia after stroke. DESIGN Single-blind randomized controlled trial. SETTING Inpatient and outpatient clinics. SUBJECTS A total of 124 patients with dysphagia after stroke were randomly divided into two groups: acupuncture and control. INTERVENTIONS The acupuncture group received standard swallowing training and acupuncture treatment. In comparison, the control group only received standard swallowing training. Participants in both groups received six days of therapy per week for a four-week period. MAIN MEASURES The primary outcome measures included the Standardized Swallowing Assessment and the Dysphagia Outcome Severity Scale. The secondary outcome measures included the Modified Barthel Index and Swallowing-Related Quality of Life, which were assessed before and after the four-week therapy period. RESULTS A total of 120 dysphagic subjects completed the study (60 in acupuncture group and 60 in control group). Significant differences existed in the Standardized Swallowing Assessment, Dysphagia Outcome Severity Scale, Modified Barthel Index, and Swallowing-Related Quality of Life scores of each group after the treatment (P < 0.01). After the four-week treatment, the Standardized Swallowing Assessment (mean difference - 2.9; 95% confidence interval (CI) - 5.0 to - 0.81; P < 0.01), Dysphagia Outcome Severity Scale (mean difference 2.3; 95% CI 0.7 to 1.2; P < 0.01), Modified Barthel Index (mean difference 17.2; 95% CI 2.6 to 9.3; P < 0.05) and Swallowing-Related Quality of Life scores (mean difference 31.4; 95% CI 3.2 to 11.4; P < 0.01) showed more significant improvement in the acupuncture group than the control group. CONCLUSIONS Acupuncture combined with the standard swallowing training may be beneficial for dysphagic patients after stroke.

Abstract
This prospective, single-blinded study investigated the validity and reliability of cervical auscultation (CA) under two conditions; (1) CA-only, using isolated swallow-sound clips, and (2) CSE + CA, using extra clinical swallow examination (CSE) information such as patient case history, oromotor assessment, and the same swallow-sound clips as condition one. The two CA conditions were compared against a fibre-optic endoscopic evaluation of swallowing (FEES) reference test. Each CA condition consisted of 18 swallows samples compiled from 12 adult patients consecutively referred to the FEES clinic. Patients' swallow sounds were simultaneously recorded during FEES via a Littmann E3200 electronic stethoscope. These 18 swallow samples were sent to 13 experienced dysphagia clinicians recruited from the UK and Australia who were blinded to the FEES results. Samples were rated in terms of (1) if dysphagic, (2) if the patient was safe on consistency trialled, and (3) dysphagia severity. Sensitivity measures ranged from 83-95%, specificity measures from 50-92% across the conditions. Intra-rater agreement ranged from 69-97% total agreement. Inter-rater reliability for dysphagia severity showed substantial agreement (rs = 0.68 and 0.74). Results show good rater reliability for CA-trained speech-language pathologists. Sensitivity and specificity for both CA conditions in this study are comparable to and often better than other well-established CSE components.
