Prevalence of Oropharyngeal Dysphagia and Its Value as a Prognostic Factor in Community-Acquired Pneumonia: A Prospective Case-Control Study.

Although oropharyngeal dysphagia (OD) is a common finding in patients with community-acquired pneumonia (CAP), specific recommendations are not provided in the current clinical guidelines. To estimate the prevalence of OD and its associated factors among patients hospitalized for CAP and to assess one-year outcomes according to the presence or absence of OD. We studied 226 patients hospitalized for CAP and 226 patients hospitalized for respiratory conditions other than CAP. We screened the risk of OD using the Eating Assessment Tool-10 (EAT-10), followed by the volume-viscosity swallow test (V-VST). A total of 122 (53.9%) patients with CAP had confirmed OD compared with 44 (19.4%) patients without CAP. Patients with CAP and OD were older (p < 0.001; 1.02-1.07) and had less familial/institutional support (p = 0.036; 0.12-0.91) compared to patients with CAP and no OD. OD was more prevalent as the CURB-65 score increased (p < 0.001). Patients with OD spent more time in the hospital (14.5 vs. 11.0 days; p = 0.038) and required more visits to the emergency room (ER). Twenty (16.4%) patients with CAP and OD died after discharge vs. one (0.8%) patient with CAP and no OD (p < 0.001; CI = 2.24-42.60). The prevalence of OD in hospitalized patients with CAP is higher than in patients hospitalized for other respiratory diagnoses. Advanced age, lower familial/institutional support, and increased CAP severity are associated with OD. Patients with CAP and OD are more frequent ER visitors after discharge and have a higher mortality. In patients with CAP and OD, aspiration pneumonia is likely underestimated.

Nutritional Status, Dietary Intake, Quality of Life, and Dysphagia in Women With Fibromyalgia.

Fibromyalgia syndrome (FMS) is an idiopathic chronic disease characterized by widespread musculoskeletal pain, hyperalgesia, and allodynia that has been recently associated with risk of dysphagia. We aimed to analyze the association between nutritional status, micro- and macronutrient intake, and quality of life (QoL) in a cohort of women with FMS and risk of dysphagia compared to women with FMS without risk of dysphagia. A cross-sectional study was conducted in 46 women with FMS. Risk of dysphagia was assessed by the Eating Assessment Tool (EAT-10) and the Volume-Viscosity Swallow Test (V-VST). The Food Frequency Questionnaire and the Swallowing Quality of Life Questionnaire were used to assess dietary intake and QoL, respectively. Thirty women with FMS were at risk for dysphagia (65.21%), assessed by the EAT-10. Based on the V-VST, the frequency of risk of dysphagia was 63.04%. Significant differences in body mass index (BMI) were found between women at risk for dysphagia and those without risk. Women at risk for dysphagia had significantly lower overall QoL scores than those women without risk. No significant differences were found for dietary intake and dysphagia risk. Women with FMS at risk for dysphagia have significantly lower BMI values and worse QoL than women without dysphagia risk, supporting the importance of assessing dysphagia in clinical practice in persons with FMS.

Abstract WMP34: Impact of Complete Oral Feeding Resumption on Nutrition and Hydration in the Rehabilitation Inpatient With Stroke

Objective: Oral feeding resumption after feeding tube placement is an important therapeutic goal for stroke patients with dysphagia. Available information on nutrition and hydration status in stroke is limited after changing intake from commercial formula for tube feeding to dysphagia diet for oral. The aim is to explore the impact on nutrition and hydration after complete oral feeding. Methods: A total of 134 stroke patients who recovered from tube feeding to complete oral feeding were enrolled in rehabilitation hospital from Jan. 2020 to Jul. 2023. The swallow function was detected by the modified Volume-viscosity Swallow Test (V-VST). If a patient completed every viscosity more than 5 mL, feeding tube would be removed. We assessed the nutritional status of stroke patients and provided strategies of dysphagia diet for patients’ food and fluid intakes. Thickeners were used to prevent the risk of aspiration. Serum biochemical measures were obtained for nutrition (prealbumin) and hydration status (BUN/Cr ratio) at admission, before removing feeding tube and within the first week following oral feeding resumption. Results: 48.51% patients could regain oral intake within 14 days from admission. Compared to admission and tube feeding phase, the level of prealbumin (mg/L) after oral feeding was significantly higher. (19.26±5.32. vs 22.57±5.03; P&lt;0.001) (20.68±5.10 v 22.57±5.03; P=0.003). Based on prealbumin 20 mg/dL, 58.21 % of patients demonstrated poor nutrition at admission and 34.33 % after oral feeding resumption. BUN/Cr &gt; 20:1 identified deficient hydration in 53.72 % of patients in tube feeding phase and 46.27 % of patients after oral intake. Differences in nutrition and hydration status were attributed to complete oral feeding resumption. Conclusion: Clinical practice of complete oral feeding resumption including evaluating swallow function of varying viscosities, dietary and fluid recommendations could achieve better nutrition and hydration status.

Convergent and discriminant validity of the Minimal Eating Observation Form – version II: a cross-sectional study

BackgroundThe Minimal Eating Observation Form – Version II (MEOF-II) is a brief and easy to use screening tool for eating difficulties, that is psychometrically robust. The aim of this study was to explore convergent (measuring similar constructs) and discriminant (measuring somewhat different constructs) validity of the MEOF-II to other validated dysphagia specific, activity and participation related instruments.MethodsIn this cross-sectional study, participants (n = 100, mean age 72, n = 42 women), diagnosed with either chronic pulmonary disease, Parkinson´s disease, Multiple Sclerosis, or stroke were recruited from rehabilitation centres. Patient-reported outcomes and clinical-rated assessments, capturing eating ability in general and swallowing in specific, included: The Dysphagia Handicap Index (DHI), the 4-question test (4QT), the Minimal Eating Observation Form – II, the Volume – Viscosity Swallow Test (V-VST), Flexible Endoscopic Evaluation of Swallowing (FEES) documented according to the Penetration-Aspiration Scale (PAS). Type of oral intake was documented using the Functional Oral Intake Scale (FOIS). Activities in daily living was assessed with Barthel index (BI). Spearman’s correlation coefficient was used to analyze associations. The MEOF-II total score was hypothesised to have moderate correlations (r ≥ 0.3) with the other assessments, besides with PAS and FOIS (weak correlations, r < 0.3).ResultsIn total 78 participants had any type of eating difficulties (MEOF-II), 69 reported dysphagia (4QT), 62 had dysphagia according to V-VST, 29 showed evidence of penetration/aspiration (PAS), and 31 participants had decreased oral intake ability (FOIS). The MEOF-II total score had moderate correlations with DHI, BI, 4QT, V-VST volume, and weak correlations with V-VST dysphagia and viscosity, PAS, and FOIS. Comparing a prior hypothesised correlation strengths against empirical findings showed that 83% of the hypothesised correlations were correct.ConclusionsThe MEOF-II is a holistic and objective screening tool that can indicate the need for further assessment and corresponds well with the persons’ subjective experiences. MEOF-II does not specifically assess the risk for penetration/aspiration.

Exploring the Feasibility of a Comprehensive Screening for Voice and Swallowing Function in Post-Extubation Patients: A Pilot Study

Objectives. This pilot study aimed to identify and test a battery of time-efficient and cost-effective voice and swallowing screening tools for post-extubated patients in Chile. Methods. A panel of four experts selected and rated voice and swallowing screening tools. Seven measures were selected: smoothed cepstral peak prominence (CPPS) and maximum phonation time (MPT) for voice assessment, Volume-Viscosity Swallow Test (V-VST) for swallowing, voluntary and reflex peak cough flow for cough assessment, Eating Assessment Tool-10 (EAT-10), and Vocal Symptom Scale (VoiSS) for patient-reported outcomes. These tools were applied to four post-extubation patients within 48-72 hours post-hospital discharge, alongside the assessment of 17 matched controls. Results. Post-extubation patients showed significantly shorter MPT, lower CPPS values, increased V-VST dysphagia signs, reduced voluntary peak cough flow, and more pronounced symptoms on both the VoiSS and EAT-10 compared to controls. Limitations. The study had a modest sample size and relied solely on clinical screening tools.Value. This pilot study suggests a feasible and cost-effective approach to voice and swallowing screening for post-extubation patients, valuable in resource-constrained settings.Conclusion. While these accessible tools are not gold-standard assessments, they offer valuable insights and can guide future research. This study underscores the potential of selected tools in facilitating early detection of voice and swallowing disorders in post-extubation patients.

Accuracy of the volume-viscosity swallow test for clinical screening of dysphagia in post COVID-19 patients

Up to 30% of patients hospitalized for COVID-19 had oropharyngeal dysphagia, particularly those in the ICU. Many cases remained underdiagnosed due to difficulties in conducting instrumental evaluations during the pandemic. Consequently, screening tests were mandatory during this period. To evaluate the accuracy of the volume-viscosity swallow test (V-VST), compared to gold standard videofluoroscopy, for screening dysphagia in a post-COVID cohort of patients. We conducted a prospective single-center study involving 58 post-COVID adult patients with no previous history of dysphagia. Blinded raters performed the index V-VST upon admission and a standardized videofluoroscopy (VFSS, the reference test) within 72h of patient intake. Oropharyngeal residue was considered a sign of impaired efficacy. Cough, decreased oxygen saturation, and voice changes were noted as signs of impaired safety. Accuracy, sensitivity, specificity, positive, and negative predictive values, and likelihood ratios were calculated for V-VST results and compared to the gold standard. Patients (aged 59.98 (SD11.53) years) spent a mean of 46.98 (SD 28.43) days in ICU, 33.76 (SD34.88) days with tracheostomy, and 19.46 (SD13.26) days in the NeuroRehabilitation Unit. The V-VST showed the following properties, compared to VFSS: sensitivity 55.6%, specificity 62.9%, positive predictive value 44.5%, negative predictive value 37.1%, and accuracy 61.5%. The V-VST showed mild accuracy, sensitivity, and specificity, compared to VFSS. Therefore, it should not be used as a stand-alone test for screening dysphagia in patients with a history of COVID.

Swallowing evaluation in patients who underwent Partial CO2 LASER Epiglottectomy for Sleep Apnea treatment

ObjectiveTo evaluate swallowing in patients who underwent CO2 LASER Partial Epiglottectomy (CO2-LPE) for Obstructive Sleep Apnea Syndrome and to assess the risk of aspiration with this technique. Material & MethodsChart review of adult patients who underwent CO2-LPE between 2016 and 2020, in a secondary care hospital. Patients underwent surgery for OSAS, in accordance to Drug Induced Sleep Endoscopy findings and an objective swallowing evaluation was done at least 6 months after surgery. Eating Assessment Tool (EAT-10) questionnaire was applied and Volume-Viscosity Swallow Test (V-VST) and Fiberoptic Endoscopic Evaluation of Swallowing (FEES) were performed. Dysphagia was classified according to Dysphagia Outcome Severity Scale (DOSS). ResultsEight patients were included in the study. The mean time between surgery and the swallowing evaluation was 50 (±13,2) months. Only 3 patients presented ≥ 3 points on EAT-10 questionnaire. Two patients presented signs of decreased efficacy of swallowing (piecemeal deglutition) but none had a decrease in safety, according to V-VST. Although 50% of the patients presented some pharyngeal residue on FEES, it was classified as trace to mild in most of the cases. No evidence of penetration or aspiration was identified (DOSS ≥ 6 in all patients). ConclusionThe CO2-LPE is a potential treatment for OSAS patients with epiglottic collapse and no evidence of swallowing safety compromise was found.

Influence of handgrip strength on pharyngeal transit time in individuals with chronic obstructive pulmonary disease.

To investigate the relationship between Handgrip Strength (HGS), dysphagia classification, nutritional aspects, and Pharyngeal Transit Time (PTT) in subjects with Chronic Obstructive Pulmonary Disease (COPD). Study based on the analysis of secondary data from a database. The sample comprised 15 COPD patients of both sexes and a mean age of 65.7 years. We collected information on HGS, videofluoroscopic swallowing study, Volume-Viscosity Swallow Test (V-VST), and Body Mass Index (BMI). We applied correlation, effect size, and logistic regression tests at the 5% significance level. Most individuals had severe COPD (66.7%), mean dominant HGS of 28.2, and non-dominant HGS of 25.3. Five subjects were malnourished, five were well-nourished, and five were obese. Most of them had normal swallowing (40%), normal V-VST results (60%), and PTT of 0.89 s (liquid) and 0.81 s (pudding-thick). There was no significant correlation between the swallowing classification and the other variables. We obtained a significant correlation (p = 0.015), though weak (r = -0.611), between non-dominant HGS and PTT. Regarding the binary logistic regression, HGS variables and HGS asymmetry were not enough to be considered a risk to clinically abnormal swallowing (V-VST). Subjects with COPD in this study had a longer PTT than reported in the literature for normal subjects and a weak correlation between PTT and non-dominant HGS. The variables related to muscle condition were not considered predictors for abnormal swallowing.

A Clinical Prediction Model Based on Post Large Artery Atherosclerosis Infarction Pneumonia.

Stroke-associated pneumonia (SAP) has been found as a common complication in acute ischemic stroke (AIS) patients. Large artery atherosclerosis (LAA) infarct is a major subtype of AIS. This study aimed to build a clinical prediction model for SAP of LAA type AIS patients. This study included 295 patients with LAA type AIS. Univariate analyses and logistic regression analyses were conducted to determine the independent predictors for the modeling purpose. Nomogram used receiver operating characteristics to assess the accuracy of the model, and the calibration plots were employed to assess the fitting degree between the model and the practical scenario. One hundred and five patients were employed for the external validation to test the stability of the model. From the univariate analysis, patients' ages, neutrophil-to-lymphocyte ratios, National Institute of Health Stroke scale (NIHSS) scores, red blood cell, sex, history of coronary artery disease, stroke location and volume-viscosity swallow test showed statistical difference in the development group for the occurrence of SAP. By incorporating the factors above into a multivariate logistic regression analysis, patients' ages, neutrophil-to-lymphocyte ratios, NIHSS, and volume-viscosity swallow test emerged as the independent risk factors of the development of SAP. The nomogram based on the mentioned 4 variables above achieved a receiver operating characteristic of 0.951 and a validation group of 0.946. The proposed nomogram is capable of predicting predict the occurrence of SAP in LAA type AIS patients, and it may identify high-risk patients in time and present information for in-depth treatment.

The Therapeutic Effect of Swallow Training with a Xanthan Gum-Based Thickener in Addition to Classical Dysphagia Therapy in Chinese Patients with Post-Stroke Oropharyngeal Dysphagia: A Randomized Controlled Study.

In patients with post-stroke oropharyngeal dysphagia (PSOD), classical dysphagia therapy (CDT) continues to provide unsatisfactory outcomes and makes it challenging for them to remove the nasal feeding tube. Increasing bolus viscosity helps prevent aspiration in PSOD. However, conventional starch thickeners enhance post-digestion residue. This study aims to evaluate the efficacy of swallow training with xanthan gum-based thickener (XGT) (Softia G, NUTRI Co., Ltd., Yokkaichi, Japan) additional to CDT in Chinese PSOD patients with a nasogastric tube when compared to CDT alone. Patients with PSOD who had a nasogastric tube were randomly assigned to either the experimental group (E-group) or the control group (C-group) in this randomized controlled, single-blind, parallel-group study. Both groups received CDT for 4 weeks. The E-group cases received additional swallow training with a Softia G-prepared hydrogel training material. The Functional Oral Intake Scale (FOIS) and modified volume-viscosity swallow test (M-VVST) for swallowing safety and efficacy according to adjusted Chinese dietary habits were administered before and after treatment. Post-training, both groups' nasogastric tube removal rates were calculated. One hundred sixty-seven participants (E-group: 82 and C-group: 85) completed the study. The E-group's median score of FOIS improved significantly than the C-group after training (median = 5 vs. 3, P < 0.001). The incidence of coughing, voice changes, oxygen desaturation of 3% or more, pharyngeal residue and piecemeal deglutition in the E-group was significantly lower than that in the C-group (P < 0.05). The E-group had 100% nasogastric tube removal, while the C-group had 28.24% (P < 0.001). Swallow training with XGT Softia G in addition to CDT can promote swallowing safety and efficacy in Chinese patients with PSOD more effectively than CDT alone.

A Systematic and Universal Artificial Intelligence Screening Method for Oropharyngeal Dysphagia: Improving Diagnosis Through Risk Management.

Oropharyngeal dysphagia (OD) is underdiagnosed and current screening is costly. We aimed: (a) to develop an expert system (ES) based on machine learning that calculates the risk of OD from the electronic health records (EHR) of all hospitalized older patients during admission, and (b) to implement the ES in a general hospital. In an observational, retrospective study, EHR and swallowing assessment using the volume-viscosity swallow test for OD were captured over 24months in patients > 70yr admitted to Mataró Hospital. We studied the predictive power for OD of 25,000 variables. ES was obtained using feature selection, the final prediction model was built with non-linear methods (Random Forest). The database included 2809 older patients (mean age 82.47 ± 9.33yr), severely dependent (Barthel Index 47.68 ± 31.90), with multiple readmissions (4.06 ± 7.52); 75.76% had OD. The psychometrics of the ES built with a non-linear model were: Area under the ROC Curve of 0.840; sensitivity 0.940; specificity, 0.416; Positive Predictive Value 0.834; Negative Predictive Value 0.690; positive likelihood ratio (LH), 1.61 and negative LH, 0.146. The ES screens in 6s all patients admitted to a 419-bed hospital, identifies patients at greater risk of OD, and shows the risk for OD in the clinician's workstation. It is currently in use at our institution. Our ES provides accurate, systematic and universal screening for OD in real time during hospital admission of older patients, allowing the most appropriate diagnostic and therapeutic strategies to be selected for each patient.

Utility of the modified Volume-Viscosity Swallow Test for bedside screening of dysphagia in critically ill patients

Aspiration and dysphagia are frequent in critically ill patients, and evidence of the validity of bedside screening tests is lacking. This study evaluated the modified Volume-Viscosity Swallow Test (mV-VST) as a screening tool for aspiration and dysphagia in intensive care unit patients. An observational, prospective longitudinal cohort single-center study included patients older than 18 years old, on mechanical ventilation for at least 48h, conscious and cooperative. Patients had been admitted in intensive care between March 2016 and August 2019at a university hospital in Spain. Data from the mV-VST and the flexible endoscopic evaluation of swallowing (FEES) test in extubated and tracheostomized patients were collected; the ROC curve was obtained for each group, and the sensitivity (Se), specificity (Sp), positive (pPV) and negative (nPV) predictive values of mV-VST were calculated and compared with the FEES results. We calculated percentages and 95% confidence intervals (CI) for qualitative variables and means or medians for quantitative variables according to the Shapiro-Wilk test. A univariate analysis identified dysphagia risk factors in each group. The study included 87 patients: 44 extubated and 43 tracheostomized with similar age, body mass index, Sequential Organ Failure Assessment, Charlson comorbidity index, type and reason for admission. Aspiration with FEES was significantly higher in extubated patients than in tracheostomized patients, 43.2% vs. 23.2%, respectively, p=0.04. With the mV-VST, aspiration was detected in 54.5% of extubated patients and in 39.5% of tracheostomized patients. In the extubated group, the Se of mV-VST to detect aspiration was 89.5%, Sp was 72%, and nPV was 90%. In the tracheostomized group, Se was 100%, Sp was 78.8%, and nPV was 100%. The ROC curve showed that mV-VST similarly identifies aspiration in extubated and tracheostomized patients. Dysphagia and aspiration are frequent amongst patients in intensive care after mechanical ventilation. The mV-VST is a valid screening tool to detect aspiration and dysphagia in extubated and tracheostomized patients.

Effect of Chin Tuck against Resistance Exercise in Citizens with Oropharyngeal Dysphagia-A Randomised Controlled Study.

Oropharyngeal dysphagia (OD) impacts the safety and efficacy of the swallowing function. The aim was to uncover the effect of chin tuck against resistance (CTAR) exercises compared to standard care in relation to the swallowing function in citizens with OD. Ninety-two citizens (46% male, median age 78 years (IQR 71, 84)) with OD confirmed by the Volume-Viscosity Swallow Test and/or Minimal Eating Observation Form version II were randomised to standard care with the addition of CTAR daily for six weeks or standard care only. The participants were included from seven Danish municipalities from March 2019 to October 2020. A nonsignificant effect on dysphagia of CTAR training combined with standard care versus standard care alone was documented. Both CTAR training combined with standard care and standard care alone had a significant effect on the swallowing function in citizens with OD, with the best effect in the group receiving CTAR training combined with standard care. A significant effect compared to baseline was observed in all participants (p = 0.03) after 12 weeks. Participants in both groups had a significant reduction in problems with manipulating food in the mouth (p = 0.005), swallowing (p = 0.005), and chewing (p = 0.03) but an increased appetite (p = 0.01). The reported quality of life scored with DHI-DK was significantly improved in both groups.

Swallowing function after acute ischemic stroke: Development and validation of a novel clinical prognostic model.

BackgroundPredicting the duration of dysphagia after acute ischemic stroke (AIS) is important for clinical treatment decisions.ObjectiveThe purpose of this study is to assess the swallowing function of AIS patients and to develop and validate a prognostic model for the need for nasogastric tube (NGT) in these patients.Materials and methodsWe included 554 AIS patients during 2018–2019 as the development group and had 186 AIS patients as the external validation group. The primary end point of the study was the retention of NGT in patients 1 week after admission (Functional Oral Intake Scale ≤ 4). Swallowing function and stroke-associated pneumonia (SAP) at 1 month post-onset were also the objectives of this study. The volume-viscosity swallow test (V-VST) was used to assess the patient’s impaired swallowing function. The Predictive model was built by logistic regression.ResultsOverall, a total of 104 patients required indwelling NGT at 1 week of AIS onset in development group. The final prognostic model includes 5 variables: age (OR: 1.085, 95%CI: 1.049–1.123), neutrophil-to-lymphocyte ratio (NLR) (OR: 1.332, 95%CI: 1.090–1.626), NIHSS (OR: 1.092, 95%CI: 1.025–1.164), history of drinking (OR: 2.532, 95%CI: 1.452–4.417) and stroke location (Subtentorial vs. Supratentorial, OR: 1.954, 95%CI: 1.088–3.509). The prediction model had an AUC of 0.810, while the external validation group was 0.794.ConclusionIn stroke patients, it is very important to decide early whether to indwell a NGT. The nomogram will support decision making for NGT insertion and help these patients recover from their condition.

Sarcopenic Dysphagia Is Associated With Mortality in Institutionalized Older Adults.

To estimate mortality associated with sarcopenic dysphagia. A 3-year follow-up cohort. Ninety-five nursing home residents were evaluated to determine the baseline presence or absence of oropharyngeal dysphagia and followed up for 3years. The primary outcome was the risk of death. Dysphagia was assessed using a volume-viscosity swallow test. We used an algorithm to determine sarcopenic dysphagia based on grip strength, walking speed, calf circumference, and exclusion of neurologic or structural causes of dysphagia. We constructed 3 subgroups: without dysphagia, nonsarcopenic dysphagia, and sarcopenic dysphagia. Cox proportional regression analyses were used to predict the risk of death. Thirty-five percent of participants had no dysphagia, 20% nonsarcopenic dysphagia, and 45% sarcopenic dysphagia. Sarcopenic dysphagia was independently associated with a higher risk of death [hazard ratio (HR) 2.44, 95% CI 1.02-5.80, P= .043] than without dysphagia. In addition, a higher Charlson Comorbidity Index score was associated with a higher risk of death (HR 1.33, 95% CI 1.01-1.75, P= .040). This study shows that sarcopenic dysphagia was associated with increased mortality among institutionalized older adults. These deaths could be potentially preventable.

The sensitivity and specificity of the modified volume-viscosity swallow test for dysphagia screening among neurological patients.

Oropharyngeal dysphagia (OD) is a highly prevalent condition after stroke and other neurological diseases. The volume-viscosity swallow test (V-VST) is a screening tool for OD. Considering that the recommendations of volume and thickeners in the original V-VST limited the popularization and application of the test in the Chinese population, we provide the modified V-VST to detect OD among neurological patients. In addition, the accuracy of the modified V-VST to screen OD needs to be verified. We included 101 patients with neurological diseases. OD was evaluated by a modified V-VST and a videofluoroscopy swallowing study (VFSS) using 3 volumes (i.e., 3, 5, and 10 ml) and 4 viscosities (i.e., water, mildly thick, moderately thick, and extremely thick). In this study, to compare with the original V-VST results, a volume of 20 ml was also included. The discriminating ability of modified V-VST in detecting OD was assessed by the sensitivity and specificity values of clinical signs of impaired efficiency (impaired labial seal, piecemeal deglutition, and residue) and impaired safety of swallowing (cough, voice changes, and oxygen desaturation ≥3%) in comparison to the results of VFSS. The modified V-VST showed 96.6% sensitivity and 83.3% specificity for OD, 85.2% sensitivity and 70% specificity for impaired safety, and 90.9% sensitivity and 76.9% specificity for impaired efficacy. Our study suggests that the modified V-VST offers a high discriminating ability in detecting OD among neurological patients.

Effect of Ingestion Training Guided by Volume-viscosity Swallow Test on Post-Stroke Dysphagia

<bold>Objective</bold> To observe the effect of ingestion training guided by volume-viscosity swallow test (V-VST) on swallowing functions and quality of life of patients with dysphagia after stroke. <bold>Methods</bold> A total of 150 patients with dysphagia after stroke who were treated in the Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University from January 2019 to December 2020, were recruited and randomly divided into control group and observation group, with 75 cases in each group. The control group received traditional rehabilitation training, such as conventional therapy, cold stimulation training, mouthwash and so on, 15 minutes a time, twice a day, six days a week, lasting for eight weeks. The observation group received ingestion training guided by the V-VST in addition to the traditional rehabilitation training methods of the control group, 10 minutes a time, three times a day, six days a week, lasting for eight weeks. Before and after treatment, video fluoroscopy swallowing study (VFSS) was used to evaluate the swallowing functions; surface electromyography analysis system was used to detect surface electromyography (sEMG) and swallowing duration; upper arm and calf circumferences were measured and nutritional risk screening 2002 (NRS 2002) was used to evaluate the nutritional status of patients; the swallowing-quality of life (SWAL-QOL) scale was used to evaluate the quality of life; Rosenbek aspiration classification standard was used to evaluate the degree of aspiration. <bold>Results</bold> 1) VFSS score: compared with those before treatment, the swallowing function scores in the pharyngeal and oral stages after treatment significantly increased in both groups (<italic>P</italic>&lt;0.05). Compared with the control group, the swallowing function scores of the observation group in the pharyngeal and oral stages were significantly higher after treatment (<italic>P</italic>&lt;0.05). 2) Swallowing duration and maximum amplitude of laryngeal muscle by sEMG: compared with those before treatment, the swallowing duration of laryngeal muscle measured by sEMG was significantly shortened and the maximum amplitude significantly increased in both groups (<italic>P</italic>&lt;0.05). Compared with the control group, swallowing duration of laryngeal muscle by sEMG of the observation group was significantly shorter and the maximum amplitude was significantly higher after treatment (<italic>P</italic>&lt;0.05). 3) Hyoid laryngeal complex mobility: compared with those before treatment, the distances of hyoid bone forward displacement and upward displacement of both groups significantly increased after treatment (<italic>P</italic>&lt;0.05). Compared with the control group, the distances of the hyoid bone forward displacement and upward displacement of the observation group was significantly higher after treatment (<italic>P</italic>&lt;0.05). 4) Nutritional status: compared with those before treatment, the upper arm and calf circumferences of both groups increased significantly after treatment, and the NRS 2002 score decreased significantly (<italic>P</italic>&lt;0.05). Compared with the control group, the upper arm and calf circumferences of the observation group were significantly greater after treatment, and the NRS 2002 score was significantly lower (<italic>P</italic>&lt;0.05). 5) Quality of life: compared with those before treatment, the SWAL-QOL scores of both groups increased significantly after treatment (<italic>P</italic>&lt;0.05). Compared with the control group, the SWAL-QOL score of the observation group was significantly higher after treatment (<italic>P</italic>&lt;0.05). 6) Degree of aspiration: compared with the control group, the degree of aspiration of the observation group was lower after treatment (<italic>P</italic>&lt;0.05). <bold>Conclusion</bold> Ingestion training guided by V-VST can improve the swallowing function of patients with dysphagia after stroke, reduce the degree of aspiration, and improve the nutritional status and quality of life.

The Quality of Life in Citizens with Oropharyngeal Dysphagia—A Cross-Sectional Study

Dysphagia is a risk factor that impaires an individual’s experience of mealtimes. Few studies contribute to the knowledge on the health-related quality of life (HRQoL) of citizens with oropharyngeal dysphagia (OD) living independently. The aim of this study involves evaluating the HRQoL in citizens living independently and suffering from OD. This cross-sectional study was performed in seven municipalities in Denmark between March 2019 and December 2020. The 90 citizens included (54% female, mean age 76.6 years (SD 0.8)) were ≥18 years, as well as diagnosed with OD using the volume-viscosity swallow test and Minimal Eating Observation Form version II. The Dysphagia Handicap Index-DK, Barthel 20, and European Quality of Life-5 Dimensions were fulfilled. Of the participating citizens, 66% of them needed additional time to eat, 64% coughed while eating, and 58% coughed while drinking. Additionally, 60% reported having a dry mouth, 62% needed to drink to succeed with swallowing foods, and 57% had to swallow multiple times. About one-third felt embarrassed when eating with others. They could not enjoy eating in the same manner as they had previously, and/or felt handicapped or limited. OD was shown to have had a high impact on the QoL in citizens with OD living independently. Focus is needed on xerostomia, as well as on the psychological aspects pertainings to mealtimes for citizens with OD.

Implementing Dysphagia Screening and Assessment in an Intermediate and Long-Stay Hospital: A Hospital-Based Quality Improvement Project

Dysphagia can occur due to a wide range of medical conditions including acute or progressive neurological disorders, trauma or surgery, with secondary effects such as dehydration and malnutrition causing an increase in morbidity and mortality rates. Dysphagia screening and assessment of swallowing function by a multidisciplinary care team is essential to identify, diagnose and manage patients with dysphagia. A cross-sectional study of dysphagia screening and assessment was performed from the 1st to the 15th of April 2022 on patients hospitalised in an intermediate and long-stay hospital in Cartagena in the southeast of Spain. The Eating Assessment Tool-10 (EAT-10) questionnaire was used as a direct-scoring screening test for dysphagia together with the standardised Volume-Viscosity Swallow Test (V-VST) in all patients with an EAT-10 score ≥ 3 points. After confirming dysphagia, different dietary and pharmaceutical interventions were performed. The following data were collected from the medical record program EKON®: age, gender, primary diagnosis, diet and texture and the use of thickener for liquids. A total of 86 patients were included in the study with a mean age of 80.0 ± 12.0 years. The mean EAT-10 score was 2.5 ± 1.7 points with 36 patients (43.9%) testing positive for being at risk of presenting dysphagia. Of these patients at risk, the V-VST detected dysphagia and the necessity of a nectar consistency in 24 patients, a honey consistency in 3 patients and a pudding consistency in 2 patients. Only 10 of the patients with dysphagia were using thickener prior to the screening and the assessment. Dietary and pharmaceutical interventions were made in the other 19 patients with dysphagia. Dysphagia screening in intermediate and long-stay hospitals is not common practice even though there is a high prevalence and important clinical repercussions. Implementing dysphagia screening and assessment protocols will improve quality of care in these patients.
