Interpretation of Sydney Swallow Questionnaire results using the oropharyngeal dysphagia risk matrix.

Oropharyngeal dysphagia (OD) commonly occurs in neuromuscular diseases (NMD). Appropriate management involves early detection, clinical evaluation, and tailored follow-up to minimize complications. Various assessment tools exist, including the Sydney Swallow Questionnaire (SSQ), a patient-reported outcome measure for assessing OD severity in adult patients. This paper proposes utilizing an innovative risk matrix (OD-Risk-Matrix) to enhance SSQ interpretation. This matrix categorizes OD risk for each SSQ question, offering valuable assistance to clinicians. This study analyzes SSQ results from a cohort of individuals with NMD (n = 57). Patients filled in the SSQ during outpatient visits at our neuromuscular center. Subsequently, SSQ scores were grouped by NMD conditions and interpreted using the OD-Risk-Matrix categorizing each question's risk as low, moderate, or high. This matrix is based on the SSQ results by categorizing the risk of OD for each question, as well as the likelihood of occurrence of OD. In light of the OD-Risk-Matrix, the interpretation of SSQ scores revealed various risk categories associated with each question, while also highlighting distinct OD characteristics and discrepancies among the different NMDs. In conclusion, the OD-Risk-Matrix offers a framework for interpreting the SSQ, revealing variations in the risks of OD among different questions in patients with NMD. This novel approach could be a valuable tool in SSQ interpretation to identify specific fields of OD and could lead to a tailored management plan, prioritizing interventions aimed at reducing the risk of aspiration, ensuring proper nutrition, and enhancing swallowing safety and efficiency.

Adaptation and Validation of the Sydney Swallow Questionnaire into Kannada (KSSQ).

Self-rating questionnaires are necessary to quantify the impairment and the impact of impairment on the quality of life, provided that these questionnaires are delivered in the patient's native language. There are no questionnaires to assess the symptom severity of oropharyngeal dysphagia in Kannada-speaking individuals. The Sydney Swallow Questionnaire (SSQ) is one such explicit tool to assess the symptoms of dysphagia, especially among patients with oropharyngeal dysphagia. The SSQ is a simple and easy-to-understand questionnaire. Therefore, the present study aimed to adapt and validate the SSQ in Kannada. English version of the SSQ was translated to Kannada and was administered to two groups of native Kannada-speaking participants - Group 1 included 53 participants (66.49 + 12.65 years) diagnosed with oropharyngeal dysphagia, and Group 2 included 53 age and gender-matched native Kannada speakers with normal swallowing ability with no history and symptoms of swallowing disorders. Cronbach's alpha was used to assess the test-retest reliability. Internal consistency was assessed using the split-half correlation. The concurrent validity of the Kannada version of SSQ (KSSQ) was measured by determining the correlation between the total scores of KSSQ and the Kannada version of Dysphagia Handicap Index (DHI). The discriminant validity was assessed by comparing the KSSQ scores between the participants of both groups. The results indicated that the KSSQ had excellent test-retest reliability, strong internal consistency, and good concurrent and discriminant validity. Therefore, it was inferred that the KSSQ is a valid and reliable tool for assessing the symptoms of dysphagia, especially among Kannada-speaking patients with oropharyngeal dysphagia.

Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios as Predictors of Dysphagia Severity and Quality of Life in Nasopharyngeal Cancer Patients after Intensity Modulated Radiotherapy (IMRT).

Background: Patients treated with definitive radiotherapy for nasopharyngeal carcinoma (NPC) develop severe dysphagia, affecting their quality of life. Traditional prognosis biomarkers are insufficient, leading to a search for new predictors like neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Methods: We retrospectively enrolled 44 NPC patients who underwent definitive radiotherapy between 2010 and 2018. EQUATOR and STROBE network guidelines were adopted. Pre-treatment evaluations were conducted, and post-treatment oropharyngeal dysphagia was assessed using the Sydney Swallow Questionnaire (SSQ) and FEES, then assigning a Dysphagia Outcome and Severity Scale (DOSS) level. Patients were divided based on NLR and PLR cut-offs, comparing subjective dysphagia (SSQ) scores and DOSS results at baseline and after a 5-year follow-up. Multiple linear regression was used for analysis. Results: At baseline, the mean NLR was 2.52 ± 1.10, and the PLR was 208.40 ± 94.35. Multivariate analysis indicated NLR and PLR as significant predictors of DOSS outcomes (p < 0.001). Conclusions: Baseline inflammation markers, such as NLR and PLR, may be used to predict dysphagia severity in NPC patients undergoing definitive radiotherapy. These markers could help identify patients at higher risk for severe dysphagia and implement tailored therapeutic and rehabilitative strategies to improve their quality of life. Further studies with larger cohorts are needed to confirm these findings and explore additional prognostic factors for dysphagia outcomes in NPC patients.

Bulbar muscle impairment in patients with late onset Pompe disease: Insight from the French Pompe registry.

Late onset Pompe disease (LOPD) is a rare neuromuscular disorder caused by a deficit in acid alpha-glucosidase. Macroglossia and swallowing disorders have already been reported, but no study has focused yet on its frequency and functional impact on patients' daily life. We reviewed 100 adult LOPD patients followed in 17 hospitals in France included in the French national Pompe disease registry. The Swallowing Quality of Life Questionnaire and the Sydney Swallow Questionnaire were completed by patients, and a specialist carried out a medical examination focused on swallowing and assigned a Salassa score to each patient. Respiratory and motor functions were also recorded. Subgroup analysis compared patients with and without swallowing difficulties based on Salassa score. Thirty-two percent of patients presented with swallowing difficulties, often mild but sometimes severe enough to require percutaneous endoscopic gastrostomy (1%). Daily dysphagia was reported for 20% of our patients and aspirations for 18%; 9.5% were unable to eat away from home. Macroglossia was described in 18% of our patients, and 11% had lingual atrophy. Only 15% of patients presenting with swallowing disorders were followed by a speech therapist. Swallowing difficulties were significantly associated with macroglossia (p = 0.015), longer duration of illness (p = 0.032), and a lower body mass index (p = 0.047). Swallowing difficulties in LOPD are common and have significant functional impact. Increased awareness by physicians of these symptoms with systematic examination of the tongue and questions about swallowing can lead to appropriate multidisciplinary care with a speech therapist and dietitian if needed.

Relationship Between Subjective Questionnaires and Videofluoroscopy of Dysphagia Evaluation: A Systematic Review and Meta-Analysis.

Early detection of dysphagia is important for preventing aspiration pneumonia. Although videofluoroscopy is currently the primary diagnostic tool for dysphagia, access to this tool may be limited because of radiation exposure risk, high cost, and other factors. In this study, a meta-analysis was used to determine the strength of the correlation between dysphagia detection outcomes obtained using subjective questionnaires and videofluoroscopy. The PubMed and Embase databases were searched for original articles up to December 2022. Studies published in English that used cross-sectional designs to assess the correlation between subjective questionnaires and videofluoroscopy were considered eligible for inclusion. The search terms used included "dysphagia," "questionnaire," and "videofluoroscopy." Two reviewers critically appraised and extracted the correlation coefficient r values. In addition, a random-effects meta-analysis was conducted. The Q statistic was used to assess the heterogeneity among the included studies. Publication bias was checked using the funnel plot and Egger's tests. Multilevel analysis was used to determine sensitivity to consider within-study correlations. In addition, subgroup analyses were conducted based on type of questionnaire, head and neck cancer, and English-speaking regions. The meta-analysis included five studies and 856 patients using the Eating Assessment Tool-10 and one study and 27 patients using the Sydney Swallow Questionnaire. The results of the random-effects meta-analysis showed a moderate relationship between the subjective questionnaires and videofluoroscopy ( r = .35, 95% CI [0.20, 0.48]). Similar results were also obtained using multilevel analysis ( r = .34, 95% CI [0.25, 0.42]). No publication bias was found for any of the studies ( p = .88). In the subgroup analyses, a moderate relationship between Eating Assessment Tool-10 and videofluoroscopy ( r = .31, 95% CI [0.19, 0.42]) and an ultrahigh relationship between Sydney Swallow Questionnaire and video-fluoroscopy ( r = .74, 95% CI [0.50, 0.87]) were found. Furthermore, moderate associations were observed within each head and neck cancer and English-speaking regions subgroup. However, no significant differences were found between these two subgroups. These results indicate the subjective questionnaires considered in this study share a moderate relationship with videofluoroscopy. Subjective questionnaires may be used as an auxiliary tool by nurses and homecare givers for the early assessment of dysphagia risk in patients.

Development and validation of an electronic version of Sydney Swallow Questionnaire.

Accurate assessment of patient-reported oropharyngeal dysphagia (OPD) is essential to guide appropriate management and evaluate response. The Sydney Swallow Questionnaire (SSQ) is a paper-based 17-item inventory developed and validated to objectively detect risk of OPD. An easy-to-use electronic version with digital output has significant potential in streamlining patient assessment. This study aims to develop and validate an electronic version of the SSQ (eSSQ) against the original paper version. The English-based paper SSQ was adapted on the online REDcap (Research Electronic Data Capture) platform to be accessible on computer and mobile devices. Patients with OPD and asymptomatic controls completed both electronic and paper versions in randomized order. Patients with stable symptoms then repeated the eSSQ after ≥14 days for test-retest reliability. Paper-based and eSSQs were also collected from an independent cohort for external validation. Agreement of total scores between both versions and eSSQ test-retest reliability were calculated using two-way mixed-effects intra-class correlation coefficient (ICC). 47 dysphagic patients, 32 controls, and 31 patients from an external validation cohort were recruited. The most common underlying etiology was head and neck cancer. Mean eSSQ total score was 789 in dysphagic patients, and 68 in controls. eSSQ had excellent agreement with paper SSQ in total scores among all participants, with ICC 0.97 (95% CI [0.93, 0.98]) in controls, 0.97 (95% CI [0.94, 0.98]) in dysphagic patients and 0.96 (95% CI [0.92, 0.98]) in validation cohort. Test-retest reliability was also excellent (ICC 0.96, 95% CI [0.90, 0.98]). The newly developed eSSQ shows excellent agreement with the paper version and test-retest reliability. Future applications of its use may allow for more efficient and accessible patient assessment.

Risdiplam improves subjective swallowing quality in non-ambulatory adult patients with 5q-spinal muscular atrophy despite advanced motor impairment

Background5q-associated spinal muscular atrophy (SMA) is characterized by the progressive loss of motor neurons with consecutive weakness and atrophy of the limb, respiratory, and bulbar muscles. While trunk and limb motor function improve or stabilize in adults with SMA under nusinersen and risdiplam treatment, the efficacy on bulbar function in this age group of patients remains uncertain. However, it is important to assess bulbar dysfunction, which frequently occurs in the disease course and is associated with increased morbidity and mortality.MethodsBulbar function was evaluated prospectively in 25 non-ambulatory adults with type 2 and 3 SMA before and 4 and 12 months after risdiplam treatment initiation using the Sydney Swallow Questionnaire (SSQ) and the bulbar subscore of the Amyotrophic Lateral Sclerosis Functional Rating Scale Revised (b-ALSFRS-R). Extremity function was assessed using the Hammersmith Functional Motor Scale Expanded (HFMSE) and Revised Upper Limb Module (RULM).ResultsSubjective swallowing quality, measured with the SSQ, improved after 12 months of therapy with risdiplam. For the b-ALSFRS-R, a non-significant trend towards improvement was observed. The RULM score improved after 12 months of risdiplam therapy, but not the HFMSE score. HFMSE and RULM scores did not correlate with the SSQ but the b-ALSFRS-R score at baseline.ConclusionsThe improvement in subjective swallowing quality under risdiplam treatment, despite an advanced disease stage with severe motor deficits, strengthens the importance of a standardized bulbar assessment in addition to established motor scores. This may reveal relevant treatment effects and help individualize treatment decisions in the future.

Development of a Dutch Version of the Sydney Swallow Questionnaire: Assessing Oropharyngeal Dysphagia Severity in Dutch-Speaking Populations.

The oropharyngeal dysphagia (OD) poses substantial health risks and affects quality of life. Patient-reported outcome measures (PROMs) are gaining prominence for their crucial role in early detection and adapting rehabilitation and management decisions. This highlights the need for culturally pertinent versions in different languages, especially when addressing conditions like OD. This study aimed to translate, culturally adapt, and assess the test-retest reliability of the Sydney Swallow Questionnaire (SSQ), a PROM designed to detect the risk of OD, for Dutch-speaking populations. The SSQ was translated and adapted based on Beaton's guidelines. Validity and test-retest reliability were assessed in 100 healthy participants, with a subset of 30 participants assessed over a 15-day interval. Intra-class correlation coefficient (ICC) values were calculated to determine test-retest reliability. The SSQ-Dutch was well received and well understood, with a median total score of 65.5/1700. Notably, 95% of participants scored below the established dysphagia risk cut-off, consistent with previous validations. The 15-day interval ICC for the SSQ-Dutch total scores was 0.82 (CI 95%: 0.66-0.91), indicating good reliability. While most questions had moderate-to-good reliability, five showed slightly lower ICC. The SSQ-Dutch emerges as a validated and reliable tool for assessing OD risk in Dutch-speaking individuals. Future studies should evaluate its efficacy in symptomatic populations and consider cultural variations in Dutch-speaking regions. The online version contains supplementary material available at 10.1007/s12070-024-04484-3.

Patient-reported outcome measures for assessing health-related quality of life in patients with voice and swallowing disorders

Standardized and validated patient surveys in the form of questionnaires are becoming increasingly important in otorhinolaryngology. Subjective symptoms and functional limitations but also health-related quality of life are assessed with so-called patient-reported outcome measures (PROMs). Besides patient history and objective findings, these questionnaires can be applied as another important source for ensuring the quality of patient-centered care. In German-speaking countries there are now several PROMs that specifically ask for the patient perspective on voice and swallowing disorders. For patients with voice disorders the following questionnaires based on the Voice Handicap Index (VHI), which are also used internationally, are mainly applied: VHI-30, VHI-12i, and VHI-9i. In the field of oropharyngeal dysphagia, the German versions of the Eating Assessment Tool-10 (EAT-10), des Sydney Swallow Questionnaire SSQ‑G, the Swallowing Quality of Life Questionnaire (SWAL-QoL), and the MD Anderson Dysphagia Inventory (MDADI) are currently mostly used.

Diagnostic utility of different dysphagia screening tools to detect dysphagia in individuals with amyotrophic lateral sclerosis.

Dysphagia is a common and serious clinical symptom of amyotrophic lateral sclerosis (ALS). The study aimed to evaluate the diagnostic utility of four dysphagia screening tools in ALS, including the ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscale, water-swallowing test (WST), Eating Assessment Tool-10 (EAT-10) and Sydney Swallow Questionnaire (SSQ). A total of 68 individuals from First Hospital, Shanxi medical university, were recruited in the study. The ALSFRS-R, WST, EAT-10, SSQ and the gold standard video fluoroscopic swallowing study (VFSS) were performed. The Penetration Aspiration Scale (PAS) during VFSS was assessed to identify unsafe swallowing (PAS ≥ 3) and aspiration (PAS ≥ 6). Receiver operator characteristic curve (ROC) analyses were performed to evaluate the accuracy of the 4 tools. Youden index was used to determine the ideal cut-off value for each tool. Of the patients, 20.59% (14/68) presented unsafety swallowing and 16.18% (11/68) had aspiration. The four tools could effectively identify patients with unsafe swallowing and aspiration. The EAT-10 had the maximum AUC (0.873 and 0.963, respectively) among the tools in the diagnosis of unsafe swallowing and aspiration. To detect unsafe swallowing and aspiration, an EAT-10 score of 6 (sensitivity: 78.6%, specificity: 87.0%) and an EAT-10 score of 8 (sensitivity: 90.9%, specificity: 91.2%), were the most appropriate cut-off points, respectively. The ALSFRS-R bulbar subscale, WST, EAT-10, and SSQ could effectively identify unsafe swallowing and aspiration in patients with ALS. Of the four tools, the EAT-10 was relatively accurate, safe, and convenient. Further studies including more patients should be conducted to verify the conclusions.

Effect of chemotherapy and radiation therapy on the swallowing of patients with head and neck cancer.

Objective: To determine the effect of Chemotherapy and Radiation Therapy on the swallowing of Patients with Head and Neck Cancer. Study Design: Cross Sectional study. Setting: Jinnah Hospital Lahore. Period: August 2020 to April 2021. Material &amp; Methods: It was performed on forty-nine adults of age range 19-58 years in having head and neck cancer and Glasgow coma scale score above 10. and purposive sampling technique was used. Patients who have received 50-70 Gy dosage and have completed at least 10 fractions of radiation therapy treatment or received 500-1000 Mg dosage and have completed at least 2 cycles of oral chemotherapy treatment were included. Sydney Swallow Questionnaire consisting of 17 questions, each with a 100mm long visual analogue scale for marking response except question 12, was filled by all participants and their responses were recorded. After 2 months of initial recordings same patients were asked to fill the same questionnaire. During therapy and post therapy results were recorded and paired sample T test was done on the data by using SPSS. Results: The results of SSQ shows 10.20% had scores depicting no swallowing difficulty. 40.82% scored 235-500 on SSQ scale showing mild symptoms of dysphagia, 30.61% show moderate swallowing impairment, 16.33% had moderately severe and 2.04% claimed severe dysphagia before the chemo and radio therapy. It represented that after chemo-radiation treatment, 4.06% had normal swallowing, 12.24% had mild issues, 24.49% had moderate, 32.65% patients claimed moderately severe dysphagia and 26.53% have severe dysphagia. Conclusion: Severity of swallowing difficulty was increased after the Chemotherapy and Radiation therapy.

Pharyngeal tongue base augmentation for dysphagia therapy: A prospective case series in patients post head and neck cancer treatment.

Dysphagia post head and neck cancer (HNC) multimodality treatment is attributed to reduced pharyngeal strength. We hypothesized that pharyngeal tongue base augmentation for dysphagia (PAD therapy) would increase pharyngeal pressures during swallowing thereby improving swallow symptoms. Adults with moderate-severe dysphagia post-HNC treatment had PAD therapy using a temporary filler (hyaluronic acid [HA]), with follow-up long-lasting lipofilling. Swallowing preprocedure and postprocedure was assessed with the Sydney Swallow Questionnaire (SSQ), High-Resolution Pharyngeal Manometry (HRPM), and Videofluoroscopic Swallowing Study (VFSS). Statistical comparison utilized paired tests. Six participants (all male; median age 64 years [IQR 56, 71]) underwent PAD therapy at a median of 47 [IQR 8, 95] months post-treatment. SSQ scores reduced from baseline (mean 1069 [95%CI 703, 1434]) to post-HA (mean 579 [76, 1081], p > 0.05), and post-lipofilling (491 [95%CI 913, 789], p=0.003, n=4). Individual participants demonstrated reduced Swallow Risk Index, Bolus Presence Time, and increased Upper Esophageal Sphincter opening, but mesopharyngeal contractile pressures were unchanged. VFSS measures of aspiration, residue, and severity were unchanged. Novel PAD therapy is safe and improves dysphagia symptoms. Biomechanical swallowing changes are suggestive of more efficacious bolus propulsion with conservative filler volume, but this was unable to resolve residue or aspiration measures.

Survivorship profile and post-treatment quality of life of oral cancer survivors in comparison with caregivers: An analysis of a real-world cohort of a developing country.

e18036 Background: Oral cavity cancer is the second most common cancer in India; India bears the most burden of oral cancer in the world. The most effective way to study the effectiveness of treatments is in clinical trials, but the quality of life (QOL) and post-treatment effects of those treatments are seldom studied in real-world settings. Methods: All oral cancer survivors treated with curative intent at our institute from September 2019 to January 2021, who were disease-free for a minimum of six months following treatment, were included in this study. The QOL of these cancer survivors was compared with that of their caregivers using the WHOQOL BREF questionnaire. The complete survivorship profile was evaluated using a Constant shoulder score for shoulder dysfunction, clinical oral dryness score (CODS) for xerostomia, Sydney Swallow Questionnaire (SSQ) for swallowing dysfunction, Patterson scale for lymphedema, Comprehensive Score for financial Toxicity (COST)‐Functional Assessment of Chronic Illness Therapy (FACIT) questionnaire for financial toxicity, Depression, Anxiety and Stress Scale - 21 Items (DASS-21) for psychological wellbeing. Results: A total of seventy-nine survivors were included. The median age was 49 years. Though both survivors and caregivers had similar QOL scores in the physical and environmental domains, survivors had poor scores in the social (M = 58.7,SD = 21.9) and psychological domains (M = 60.4,SD = 15.6). The T stage (p = 0.06), surgery (p = 0.008), and trismus (p = 0.03) were significant factors affecting swallowing. Those patients who had undergone selective neck dissection had better shoulder scores compared to those who had modified radical neck dissection (p = 0.006). 75% of people had xerostomia and 10.9% had severe xerostomia. Internal lymphedema was seen in 30.4% of people. Depression and anxiety were recorded in 46 (58.2%) and 33 (41.8%) patients respectively. Employment status (p = 0.04) and treatment modality (p = 0.05) were significant factors affecting financial toxicity. Conclusions: Oral cancer survivors had a poor psychosocial QOL compared to their caregivers. Treatment-related functional sequelae had a significant negative impact on quality of life across all domains. Clinical trial information: CTRI/2020/07/026848.

Validity and Reliability of the Turkish Version of the Sydney Swallow Questionnaire.

This study aimed to assess the validity and reliability of the Turkish version of the Sydney Swallow Questionnaire (SSQ-T) and calculate a cutoff value to help clinicians to suspect/predict oropharyngeal dysphagia (OPD). The original questionnaire was translated into Turkish by two bilingual English Turkish translators. The study included 170 Turkish adult subjects. Half of the participants were patients presenting with OPD, and half were healthy controls. Fiberoptic endoscopic evaluation of swallowing (FEES) was administered to all subjects. Patients were evaluated using the Turkish Penetration Aspiration Scale and the Yale Pharyngeal Residue Severity Rating Scale. Additionally, the final version of the SSQ-T questionnaire and the Turkish Eating Assessment Tool were administered to all subjects. Internal consistency was high on all questions (Cronbach's α = .974). Test-retest reliability was also high (intraclass correlation coefficient = .975, p < .001; 95% confidence interval [.948-.988]). The SSQ-T score range was 0-1,240 for all participants, 57-1,240 for the patients with OPD, and 0-152 for the healthy controls. The cutoff value was 174 with 85.96% sensitivity and 99.12% specificity. The SSQ-T was demonstrated to be a valid and reliable assessment to assess the self-perceived severity of OPD.

The Impact of Nasogastric Feeding Tube on Physiologic Swallow in Head and Neck Cancer Patients: A Multidisciplinary Clinical Trial

<h3>Purpose/Objective(s)</h3> Nasogastric feeding tubes (NGT) are ubiquitous within the head and neck (H&N) cancer patient population. NGT are often placed in post-surgical H&N cancer patients to allow for healing of suture lines in oral cavity and oropharyngeal free flap patients and are also used in transoral robotic surgery (TORS) patients. Despite their widespread use, the impact of NGT on the physiologic swallow of H&N cancer patients remains unknown. In the neurology literature, there is data demonstrating alterations in the functional swallow of elderly post-stroke patients with NGTs. This showed significant differences in pharyngeal transit time of an ingested barium bolus, with increased barium residue in the vallecula and pyriform sinus with the NGT in place, suggesting the NGT itself plays a role in altering physiologic swallow. The goals of the present study are twofold: 1: Determine the effects of an indwelling NGT on swallowing function in head and neck surgery patients. We hypothesize that the NGT will impair the physiologic swallow function resulting in a higher likelihood of laryngeal penetration and aspiration. 2: Determine the effect of an NGT on head and neck surgery patients perceived ability to swallow. We hypothesize that the presence of the NGT will negatively affect participants perception of their own ability to swallow. <h3>Materials/Methods</h3> This study was approved by our institutional review board (clinical trial VICC HN 2102). A multidisciplinary team involving H&N surgeons, speech language pathologists, and radiologists were critical in the development of this project. This is a crossover trial in which participants serve as their own control. Inclusion criteria include adult patients who underwent oral cavity or oropharyngeal cancer surgery including TORS and received an NGT as part of their standard of care. Exclusion criteria included altered mental status, need for long-term enteral feeding (i.e. NGT could not be safely removed to allow the patient to receive all nutrition via oral intake) and total or partial laryngectomy. Participants will complete two surveys about their subjective swallow, the Sydney Swallow Questionnaire and a 5-question supplemental survey utilizing a visual analog scale. They will undergo a video fluoroscopic swallow study (VFSS) with the NGT in place with thin and thick barium consistencies. The NGT is then removed and the two surveys and VFSS are repeated without the NGT in place. Objective measurements collected during the VFSS include oral, pharyngeal, and esophageal transit times and the penetration-aspiration scale scores. Ten of planned forty participants have been enrolled in the study. <h3>Results</h3> TBD <h3>Conclusion</h3> TBD

Swallowing biomechanics before and following multi-level upper airway surgery for obstructive sleep apnea.

The effect of contemporary multi-level upper airway surgery for obstructive sleep apnea on swallowing is unclear. This study assessed the biomechanical swallowing function in participants with obstructive sleep apnea pre- and post-modified uvulopalatopharyngoplasty and coblation channeling of the tongue. In this prospective, longitudinal study, adults diagnosed with moderate-severe obstructive sleep apnea who underwent modified uvulopalatopharyngoplasty and coblation channeling of the tongue surgery had swallowing biomechanics assessed using high-resolution pharyngeal manometry and analyzed with swallowgateway.com. Symptomatic swallowing difficulty was evaluated using the Sydney Swallow Questionnaire (≥ 234). General linear mixed-model analysis was conducted to evaluate the difference pre- and post-modified uvulopalatopharyngoplasty and coblation channeling of the tongue. Data are presented as mean [95% confidence intervals]. High-resolution pharyngeal manometry assessments were conducted in 10 participants (7 men; median age 50 [interquartile range 36-65]) preoperatively and repeated postoperatively at 9 months [interquartile range 6-13]. Self-reported dysphagia was unchanged following surgery (Sydney Swallow Questionnaire =149 [53, 447] to 168 [54, 247]; P = .093). High-resolution pharyngeal manometry outcomes indicated reduced mesopharyngeal pressures (148 [135, 161] to 124 [112, 137] mm Hg s cm; P = .011), reduced hypopharyngeal pressures (113 [101, 125] to 93 [84, 102] mm Hg s cm; P = 0.011), and reduced upper esophageal sphincter relaxation pressure (5 [4, 6] to 2 [1,3] mm Hg; P = 0.001) but no change to velopharyngeal pressures (135 [123, 147] to 137 [117, 157] mm Hg s cm; P = .850) postsurgery. Modified uvulopalatopharyngoplasty may have less implications on the swallow mechanism than previously suspected. In contrast, the reduction in mesopharyngeal contractile pressures associated with coblation channeling of the tongue, although within normal limits, may affect bolus propulsion. Biomechanical alterations were insufficient to worsen self-reported swallowing function. Schar MS, Omari TI, Woods CW, etal.

Cricopharyngeal peroral endoscopic myotomy improves oropharyngeal dysphagia in patients with Parkinson's disease.

Background and study aims Oropharyngeal dysphagia (OPD) is prevalent in patients with Parkinson’s disease (PD). Upper esophageal sphincter (UES) dysfunction is an important pathophysiological factor for OPD in PD. The cricopharyngeus (CP) is the main component of UES. We assessed the preliminary efficacy of cricopharyngeal peroral endoscopic myotomy (C-POEM) as a treatment for dysphagia due to UES dysfunction in PD. Patients and methods Consecutive dysphagic PD patients with UES dysfunction underwent C-POEM. Swallow metrics derived using high-resolution pharyngeal impedance manometry (HRPIM) including raised UES integrated relaxation pressure (IRP), raised hypopharyngeal intrabolus pressure (IBP), reduced UES opening caliber and relaxation time defined UES dysfunction. Sydney Swallow Questionnaire (SSQ) and Swallowing Quality of Life Questionnaire (SWAL-QOL) at before and 1 month after C-POEM measured symptomatic improvement in swallow function. HRPIM was repeated at 1-month follow-up. Results C-POEM was performed without complications in all (n = 8) patients. At 1 month, there was an improvement in both the mean SSQ (from 621.5 to 341.8, mean difference –277.3, 95 %CI [–497.8, –56.7], P = 0.02) and SWAL-QOL (from 54.9 to 68.3, mean difference 9.1, 95 %CI [0.7, 17.5], P = 0.037) scores. Repeat HRPIM confirmed a decrease in both the mean UES IRP (13.7 mm Hg to 3.6 mm Hg, mean difference –10.1 mm Hg, 95 %CI [–16.3, –3.9], P = 0.007) and the mean hypopharyngeal IBP (23.5 mm Hg to 10.4 mm Hg, mean difference –11.3 mm Hg, 95 %CI [–17.2, –5.4], P = 0.003). Conclusions In dysphagic PD patients with UES dysfunction, C-POEM is feasible and enhances UES relaxation and reduces sphincteric resistance to flow during the swallow, thereby improving dysphagia symptoms.

Comparison of Self-Report of Dysphagia Using the Eating Assessment Tool and the Sydney Swallowing Questionnaire in Community Dwelling Older Adults

Purpose Patient-reported outcomes (PROs) are an important feature in clinical evaluation of swallowing. The Eating Assessment Tool (EAT-10) and the Sydney Swallow Questionnaire (SSQ) are two validated dysphagia PROs commonly used in healthy older adult populations as screening tools for swallowing problems. The purpose of this study is to compare the consistency of the EAT-10 and SSQ scores for self-reported swallowing difficulties in a group of community-dwelling older adults (CDOA) completing both questionnaires. Method A total of 316 individuals over the age of 60 years completed the EAT-10, SSQ, and provided demographic data, including a self-report of any medical diagnoses. Participants were excluded if they had any diagnoses known to cause dysphagia. Questionnaire responses were analyzed for frequencies of responses across all participants. Results Seventy-five participants were identified as having dysphagia by the EAT-10 (23.7%), while 30 participants were identified by the SSQ (9.49%). When comparing the results of the two assessments, the scales agreed on 289 out of 316 participants (91%). There was a disagreement on the results in 27 of the 316 participants, with 26 of these self-reporting dysphagia symptoms on the EAT-10 but not on the SSQ. Conclusions Two commonly used dysphagia PROs resulted in different prevalence rates of self-reported dysphagia in a group of CDOA. CDOAs may need questionnaires specifically validated for them with special consideration for specific age-related risk factors, to ensure accurate early identification.

Assessment of Bulbar Function in Adult Patients with 5q-SMA Type 2 and 3 under Treatment with Nusinersen.

The antisense oligonucleotide nusinersen has been shown to improve trunk and limb motor function in patients with spinal muscular atrophy (SMA). Bulbar dysfunction, which is regularly present in SMA, is not captured by standard motor scores, and validated measurement instruments to assess it have not yet been established. Data on whether and how bulbar function changes under gene-based therapies in adult SMA patients are also unavailable. Here, we present data on the course of bulbar dysfunction assessed prospectively before nusinersen treatment initiation and 6 and 14 months later in 23 adult SMA patients using the Sydney Swallow Questionnaire (SSQ) and the bulbar subscore of the Amyotrophic Lateral Sclerosis Functional Rating Scale Revised (ALSFRS-R). While no improvement in bulbar scores was observed under treatment with nusinersen, the absence of a decline still implies a therapeutic effect of nusinersen on bulbar dysfunction. The results of this study aim to contribute to a standardized assessment of bulbar function in adult SMA patients, which may show therapeutic effects of gene-based therapies that are not evident from standard motor scores.

Cross-cultural adaptation of the SWAL-QOL and the Sydney Swallow Questionnaire (SSQ) into French-Canadian and preliminary assessment for their use in an oculopharyngeal muscular dystrophy (OPMD) population

Patient-reported outcomes (PRO) assessing dysphagia are an essential component of clinical trials to consider how patients feel and function in response to treatments. The selected PRO needs to be translated in several languages using a systematic process ensuring its validity and equivalence for use in multicenter clinical trials. The main objectives were to translate the SWAL-QOL and the Sydney Swallow Questionnaire (SSQ) into French Canadian (SWAL-QOL-FC and SSQ-FC) and to assess their appropriateness for patients with oculopharyngeal muscular dystrophy (OPMD).A forward- and back-translation process was followed including independent mother-tongue translators followed by committee review. Known-groups validity was assessed by comparing scores of OPMD French-Canadian participants (n = 21) known to differ in dysphagia severity according to the 80-ml drinking test score. A Mann-Whitney test was used to compare the mean scores. Cognitive interviews were conducted later on to ensure a posteriori cultural equivalence among French-Canadian participants (n = 28).Evidences of adequate known-groups validity was shown for the SSQ-FC. Only two domains out of 10 of the SWAL-QOL-FC (burden and eating duration) showed adequate known-groups validity. In addition, the difference in the mean composite score was not significant. Several conceptual equivalence issues were found in both questionnaires as a result of the cognitive interviews.This study provided evidence that the SSQ-FC presents better validity than the SWAL-QOL-FC in a small sample size of OPMD participants. The findings of the cognitive interviews suggest the need to develop an OPMD-specific questionnaire to capture better the whole spectrum of disease severity.
