RESUMEN

AIM: To reveal the characteristics and the oral function of institutionalized frail older adults and the factors contributing to frailty. METHODS: This multicenter, cross-sectional study included 214 patients. A questionnaire was administered to registered dietitians from these institutions. Sex, age, height, weight, grip strength, calf circumference, level of care need, FRAIL-NH, MNA® -SF, dysphagia, food form and water thickening, number of medications, major diseases, comorbidities, independence in daily living of older people with dementia, use of medication with dry mouth, nutritional care issues (malnutrition-related problems) by multiple occupations in Nutrition and Eating Swallowing Screening, Assessment and Monitoring, and nine oral-related items were evaluated. RESULTS: One hundred six patients (49.5%) were classified as frail, 75% of the patients were women, and the mean BMI was 19.7 kg/m2. Older adults with frailty were characterized by high care needs, malnutrition, multiple comorbidities, multiple medications, eating and swallowing disorders, the requirement of feeding assistance, and the need to adjust the shape of meals and fluids. The multivariable OR (95%CI) for "choking and residue problems" was 1.81 (1.20-2.73), while that for "dietary concentration problems" was 4.28 (2.10-8.74). CONCLUSION: Caregivers must maintain posture and provide meal assistance. Professionals in various occupations must adjust the proper food form and medication content. Meal times must be examined in consideration of the times at which drugs will be most effective. Oral care must be provided, and an environment must be created to help the subject concentrate. Focusing on problems of choking, residue, and concentration on meals is expected to improve frailty, aspiration pneumonia, and the prognosis of institutionalized older adults.

RESUMEN

OBJECTIVE: This study aimed to evaluate the effects of early swallowing rehabilitation on safe oral feeding in dysphagia patients following traumatic brain injury. METHODS: Sixty-nine patients were divided into intervention and control groups, with the intervention group receiving swallowing rehabilitation therapy. The severity of swallowing disorders, cognitive function, and level of consciousness were assessed using the Mann Assessment of Swallowing Ability (MASA), Rancho Los Amigos (RLA), and Glasgow Coma Scale (GCS) before and after the intervention. Additionally, data on ventilator use duration and hospital stay length were collected. RESULT: The intervention group exhibited a significant improvement in MASA scores (68.58) compared to the control group (38.10). No significant differences were observed in GCS and RLA scores post-intervention, indicating similar levels of consciousness and cognitive function between groups. While the duration of ventilator use was comparable, the intervention group achieved safe oral swallowing 12.12 days earlier than the control group. DISCUSSION: The findings demonstrate that early swallowing rehabilitation significantly enhances recovery dysphagia post-brain injury, as evidenced by improved MASA scores and earlier achievement of safe oral feeding, despite no notable changes in cognition or consciousness. This underscores the importance of implementing early rehabilitation strategies in clinical practice.

RESUMEN

OBJECTIVE: To identify internal structure validity evidence of a dysphagia screening questionnaire for caregivers of older adults with Alzheimer's disease dementia and/or vascular dementia. METHODS: The 24-question Dysphagia Screening in Older Adults with Dementia - Caregiver Questionnaire (RaDID-QC) was administered by interviewing 170 caregivers of older people with dementia, selected by convenience at the Outpatient Reference Center for Older People. Exploratory Factor Analysis (EFA) was used to assess the internal structure validity of the questionnaire, and Cronbach's alpha was used to analyze reliability. Questions with factor loadings lower than 0.45 in magnitude were removed from the final questionnaire. Multivariate multiple linear regression was used to assess the percentage of variance explained by the remaining questions. RESULTS: Kayser-Meyer-Olkin (KMO) and Bartlett's tests suggested that the questionnaire was adequate for EFA. Principal Component Analysis (PCA) suggested that 12 components captured at least 75 % of the total variance. The corresponding 12-factor EFA model showed a statistically significant fit, and 15 out of the 24 questions had factor loadings greater than 0.45. Cronbach's alpha was 0.74 for the 15 questions, which explained 71 % of the total variance in the complete dataset. The questionnaire has adequate internal structure validity and good reliability. Based on EFA, RaDID-QC decreased from 24 to 15 questions. Other internal validity and reliability parameters will be obtained by administering the questionnaire to larger target populations. CONCLUSION: The RaDID-QC applied to caregivers of older adults with dementia due to Alzheimer's disease and/or vascular dementia produced valid and reliable responses to screen dysphagia signs and symptoms.

RESUMEN

Introduction: The increasing incidence of stroke globally has led to dysphagia becoming one of the most common complications in stroke patients, with significant impacts on patient outcomes. Accurate early screening for dysphagia is crucial to avoid complications and improve patient quality of life. Methods: Included studies involved stroke-diagnosed patients assessed for dysphagia using bedside screening tools. Data was sourced from Embase, PubMed, Web of Science, Scopus, and CINAHL, including publications up to 10 December 2023. The study employed both fixed-effect and random-effects models to analyze sensitivity, specificity, positive predictive value (PPV), and Negative Predictive Value (NPV), each with 95% confidence intervals. The random-effects model was particularly utilized due to observed heterogeneity in study data. Results: From 6,979 records, 21 studies met the inclusion criteria, involving 3,314 participants from 10 countries. The analysis included six assessment tools: GUSS, MASA, V-VST, BSST, WST, and DNTA, compared against gold-standard methods VFSS and FEES. GUSS, MASA, and V-VST showed the highest reliability, with sensitivity and specificity rates of 92% and 85% for GUSS, 89% and 83% for MASA, respectively. Heterogeneity among studies was minimal, and publication bias was low, enhancing the credibility of the findings. Conclusion: Our network meta-analysis underscores the effectiveness of GUSS, MASA, and V-VST in dysphagia screening for stroke patients, with high sensitivity and specificity making them suitable for diverse clinical settings. BSST and WST, with lower diagnostic accuracy, require more selective use. Future research should integrate patient-specific outcomes and standardize methodologies to enhance dysphagia screening tools, ultimately improving patient care and reducing complications.

RESUMEN

The global population is aging at an unprecedented rate, resulting in a growing and vulnerable elderly population in need of efficient comprehensive healthcare services that include long-term care and skilled nursing facilities. In this context, severe aspiration pneumonia, a condition that carries substantial morbidity, mortality, and financial burden, especially among elderly patients requiring admission to the intensive care unit, has attracted greater concern. Aspiration pneumonia is defined as a pulmonary infection related to aspiration or dysphagia in etiology. Prior episodes of coughing on food or liquid intake, a history of relevant underlying conditions, abnormalities on videofluoroscopy or water swallowing, and gravity-dependent shadow distribution on chest imaging are among the clues that suggest aspiration. Patients with aspiration pneumonia tend to be elderly, frail, and suffering from more comorbidities than those without this condition. Here, we comprehensively address the epidemiology, clinical characteristics, diagnosis, treatment, prevention, and prognosis of severe aspiration community-acquired pneumonia in the elderly to optimize care of this high-risk demographic, enhance outcomes, and minimize the healthcare costs associated with this illness. Emphasizing preventive measures and effective management strategies is vital in ensuring the well-being of our aging population.

RESUMEN

This study aims to develop and validate the content and response processes of a questionnaire intended for caregivers to screen for dysphagia in Brazilian older adults with dementia due to Alzheimer's disease and/or vascular dementia. The instrument items were developed in Brazilian Portuguese language based on the theoretical framework. A committee of speech-language-hearing therapists analyzed the relevance, objectivity, clarity, and understandability of the items with the Delphi method. The content validity index cutoff agreement score for experts' answers to validate each item in the questionnaire was 0.78; in the intraclass correlation coefficient, it was 0.75 for all items. For response process validity evidence, the questionnaire was applied to 30 caregivers of older adults with dementia, who judged the clarity and understandability of the items. Each item was validated when understood by at least 95% of participants. The first version of the instrument had 29 items. After two expert assessments, the last version had 24 items. The intraclass correlation coefficient was 0.85. Only one item needed semantic adjustments in the pre-test. The dysphagia screening instrument applied to caregivers of older adults with dementia was developed with adequate content and response process validity evidence, enabling adjustments in its construct. Future studies will analyze the remaining evidence of validity and reliability.

RESUMEN

INTRODUCTION/AIMS: Objective and practical biomarkers to determine the need for gastrostomy in patients with amyotrophic lateral sclerosis (ALS) are lacking. Tongue pressure (TP) is a promising biomarker because it is associated with bulbar dysfunction. The aims of this study were to evaluate the association of TP with the need for gastrostomy, and to determine its optimal cut-off value. METHODS: This prospective observational study included participants with ALS taking nutrition orally. TP was evaluated using the Iowa Oral Performance Instrument. Need for gastrostomy as determined by a multidisciplinary team during a 12-month follow up period was recorded. Associations between TP and need for gastrostomy placement were performed. ROC curve analysis determined the optimal cut-off value of TP to predict gastrostomy. RESULTS: Of 208 screened participants, 119 were included. Gastrostomy was indicated in 45% (53), in a 12-month follow up period. TP of ≤20 kPA was a strong predictor of gastrostomy indication (OR 11.8, CI 95% [4.61, 34.7], p < .001). The association persisted even after adjustment for weight loss, pneumonia, prolonged feeding duration, Revised ALS Functional Rating Scale score, and American Speech-Language-Hearing Association scale score (OR 4.51, CI 95% [1.50, 14.9], p = .009). By receiver operating characteristic curve analysis, 20 kPA represented the optimal cut-off value (sensitivity 0.75, specificity 0.89). DISCUSSION: TP is a strong independent predictor of gastrostomy indication in the subsequent 12 months in patients with ALS, with good sensitivity and specificity at a cutoff value of ≤20 kPA, suggesting that it may be a promising biomarker in clinical practice.

RESUMEN

OBJECTIVES: To investigate the relationship between malnutrition and potential contributing factors such as poor oral health, dysphagia and mortality among older people in short-term care. METHODS: This cross-sectional study is a part of the multidisciplinary multicentre project SOFIA (Swallowing function, Oral health and Food Intake in old Age), which includes older people (≥65 years) in 36 short-term care units in five regions of Sweden. Nutritional status was measured with version II of the Minimal Eating Observation and Nutrition Form (MEONF-II), oral health with the Revised Oral Assessment Guide (ROAG), dysphagia with a water swallow test, and the mortality rate was followed for 1 year. Data were analysed using descriptive analysis and logistic regression models to calculate odds ratios for the association between malnutrition and these factors. RESULTS: Among the 391 participants, the median age was 84 years and 53.3% were women. Mortality rate was 25.1% within 1 year in the total group, and was higher among malnourished participants than among their well-nourished counterparts. Severe dysphagia (OR: 6.51, 95% CI: 2.40-17.68), poor oral health (OR: 5.73, 95% CI: 2.33-14.09) and female gender (OR: 2.2, 95% CI: 1.24-3.93) were independently associated with malnutrition. CONCLUSION: Mortality rate was higher among malnourished people than those who were well nourished. Severe dysphagia, poor oral health and female gender was predictors of malnutrition among older people in short-term care. These health risks should be given more attention in short-term care with early identification.

RESUMEN

PURPOSE: The aim of this systematic review was to assess the role of hyperbaric oxygen therapy  (HBOT) in patients with dysphagia after radiation therapy for head and neck cancer. METHOD: A systematic search was conducted in the electronic databases Ovid MEDLINE, Ovid Embase, and Cochrane Central Register of Controlled Trials for relevant studies until March 14, 2023. No restriction on language or publication date. The criteria for inclusion: patients with HNC who had received both radiation therapy and HBOT as 1) a preventive treatment against swallowing difficulties, 2) to preserve swallowing function, or 3) to promote swallowing difficulties. RESULTS: We identified 1396 records. After removal of 31 duplicates, 1365 records were accessible for title and abstract screening. This yielded 53 studies for full text assessment. Six studies met the eligibility criteria and were included for qualitative analysis. CONCLUSION: Evidence of HBOT benefits in patients with dysphagia after radiation therapy for head and neck cancer is inconsistent. Well-designed studies using validated outcome measures and long-term follow-up are warranted.

RESUMEN

INTRODUCTION: Acquired swallowing impairment is a major public health issue that often leads to increased morbidity and slower recovery. Speech and language therapists (SLTs) have taken the lead in the assessment and treatment of dysphagia, which is reflected in guidelines where early intervention is recommended. This is in addition to the central role that SLTs play in the management of acquired communication impairments since research indicates that patients with communication difficulties benefit from early and intensive therapy by SLTs. This increasing demand for SLTs is expected to cause conflicting pressures in their workload and, therefore, beneficial to consider workforce planning. The aim of this study was to examine real-world data in the UK to investigate this issue regarding changes in referral patterns of patients with dysphagia and/or communication disorders to SLTs over time, to assist with workforce planning. METHODS: We interrogated the Royal College of Speech and Language Therapists Online Outcome Tool, a national database, in this retrospective cohort study. We included patients evaluated between 2018 and 2022. We performed a subgroup analysis of patients aged ≥40 years who had a primary medical diagnosis of stroke. Data on age, primary diagnosis, time on caseload, primary Therapeutic Outcome Measure (TOM) scale and initial TOM score on impairment were examined. RESULTS: From the database of 44,444 referrals to speech and language therapy, 5,254 referrals were included in the stroke and overall subgroup analyses. Referrals were 55.1% male, with a median age of 71 years. More than half (56.1%) of these referrals were for dysphagia. Referrals decreased during the COVID-19 pandemic but began to recover from 2021 onwards. The time on the SLT caseload has increased over the years from a median of 14 days (interquartile range [IQR] 0-56) in 2018 to 20 days (IQR: 3-81) in 2022. While there were more referrals to SLT services for assessment and management of dysphagia than for communication in the overall population, in the stroke subgroup, referrals for communication disorders outnumbered referrals for dysphagia from 2020 onwards. Additionally, the severity of impairment on referral increased over the years. CONCLUSION: Real-world data indicates that referrals to SLT services are changing over time to include more complex and severely impaired patients, with a demand for both swallowing and communication disorders. These findings should inform staff allocation and remodelling of education/training for SLTs to better meet clinical and public health needs. The retrospective nature of this study limits the strength and generalisability of these data, and this topic warrants further investigation.

RESUMEN

INTRODUCTION: It is important for the endoscopic thyroid surgeon to understand the pros and cons of trans-oral endoscopic thyroidectomy-vestibular approach (TOETVA) vis-à-vis, open conventional thyroidectomy (OTx) so he/she can help patients in making informed choices regarding the type of procedure to opt for. Swallowing related quality of life (SWAL-QoL) has not been compared between the two approaches. Using a rigorous qualitative methodology and validated reliable tool, this study set out to compare the swallowing related quality of life in patients undergoing TOETVA versus OTx. METHODS: Prospective study at 3 time points in patients planned for hemithyroidectomy (Preoperative, 1 week and 12 weeks). Data were collected on patients at a tertiary teaching institute in India. Participants ranged from age 18-60 years with a diagnosis of benign euthyroid nodule undergoing hemithyroidectomy. Exclusion criteria were-(1) pre-existing vocal cord abnormalities, (2) undergoing surgery for recurrent nodules, and (3) any neuro-muscular disease affecting swallowing ability. Main outcome measure was comparison of swallowing related quality of life domain scores between patients undergoing hemithyroidectomy via either endoscopic trans-oral or open approach. RESULTS: Of the 82 included patients, 40 underwent TOETVA and 42 OTx. Both the groups were comparable in terms of demographic and clinicopathological profile. The mean preoperative SWAL-QOL scores were comparable in all domains. Mean SWAL-QoL scores for all domains on postoperative day 7 were significantly better in TOETVA group with domains burden, eating desire, mental health and communication having medium effect sizes. Physical symptom domain was better in the OTx group but had a small effect size. The difference in SWAL-QoL domains between the two groups persisted for 3 months also. CONCLUSION: Swallowing related quality of life after trans-oral endoscopic thyroidectomy compared to conventional open surgery has not been reported in the literature. Our findings suggest that trans-oral endoscopic thyroidectomy results in significant superior swallowing related quality of life in the majority of domains.

RESUMEN

Background/Objectives: The Dysphagia Handicap Index (DHI) is commonly used in oropharyngeal dysphagia (OD) research as a self-report measure of functional health status and health-related quality of life. The DHI was developed and validated using classic test theory. The aim of this study was to use item response theory (Rasch analysis) to evaluate the psychometric properties of the DHI. Methods: Prospective, consecutive patient data were collected at dysphagia or otorhinolaryngology clinics. The sample included 256 adults (53.1% male; mean age 65.2) at risk of OD. The measure's response scale, person and item fit characteristics, differential item functioning, and dimensionality were evaluated. Results: The rating scale was ordered but showed a potential gap in the rating category labels for the overall measure. The overall person (0.91) and item (0.97) reliability was excellent. The overall measure reliably separated persons into at least three distinct groups (person separation index = 3.23) based on swallowing abilities, but the subscales showed inadequate separation. All infit mean squares were in the acceptable range except for the underfitting for item 22 (F). More misfitting was evident in the Z-Standard statistics. Differential item functioning results indicated good performance at an item level for the overall measure; however, contrary to expectation, an OD diagnosis presented only with marginal DIF. The dimensionality of the DHI showed two dimensions in contrast to the three dimensions suggested by the original authors. Conclusions: The DHI failed to reproduce the original three subscales. Caution is needed using the DHI subscales; only the DHI total score should be used. A redevelopment of the DHI is needed; however, given the complexities involved in addressing these issues, the development of a new measure that ensures good content validity may be preferred.

RESUMEN

Pediatric swallowing disorders are common yet often overlooked neuro-muscular system diseases that significantly impact the quality of life and development of affected children. This study aims to explore the effect of combined application of oral rehabilitation training and neuromuscular electrical stimulation on improving pediatric swallowing disorders. Children meeting the inclusion criteria for swallowing disorders were divided into control and experimental groups based on different intervention protocols. The experimental group received combined oral rehabilitation training and neuromuscular electrical stimulation, while the control group received only oral rehabilitation training. Results showed that the intervention was more effective in the experimental group, with shorter recovery time for normal swallowing function and improved nutritional status and quality of life. This study provides scientific evidence for clinical treatment of pediatric swallowing disorders. In conclusion, the combined application of oral rehabilitation training and neuromuscular electrical stimulation effectively improves pediatric swallowing disorders, with superior efficacy compared to single treatment methods. Further research is needed to elucidate the mechanism of action and optimize treatment protocols to enhance the therapeutic outcomes and prognosis of pediatric swallowing disorders.

RESUMEN

PURPOSE: Dysphagia is a prevalent symptom observed in acute stroke. Several bedside screening tests are employed for the early detection of dysphagia. Pulse oximetry emerges as a practical and supportive method to augment the existing techniques utilized during bedside swallowing assessments. Desaturation levels, as measured by pulse oximetry, are acknowledged as indicative of aspiration by certain screening tests. However, the predictive capability of pulse oximetry in determining aspiration remains a subject of controversy. The objective of this study was to compare aspiration and oxygen desaturation levels by time and aspiration severity in dysphagic patients compared to healthy controls. It also aimed to evaluate the accuracy of pulse oximetry by comparing it with VFSS findings in detecting aspiration in both liquid (IDDSI-0) and semi-solid (IDDSI-4) consistencies. MATERIALS AND METHODS: Eighty subjects (40 healthy and 40 acute stroke patients) participated. Patients suspected of dysphagia underwent videofluoroscopy as part of the stroke unit's routine procedure. Baseline SpO2 was measured before VFSS, and stabilized values were recorded. Sequential IDDSI-0 and IDDSI-4 barium tests were conducted with 5 ml boluses. Stabilized SPO2 values were recorded during swallowing and 3-min post-feeding. Patients with non-dysphagia received equal bolus monitoring. Changes in SPO2 during, before, and after swallowing were analyzed for each consistency in both groups. RESULTS: The study revealed a statistically significant difference in SPO2 between patients with dysphagia and controls for IDDSI-4 and IDSSI-0. In IDDSI-4, 20% of patients experienced SpO2 decrease compared to 2.5% in control group (p = 0.013). For IDDSI-0, 35% of patients showed SpO2 decrease, while none in the control group did (p = 0.0001). Aspiration rates were 2.5% in IDDSI-4 and 57.5% in IDDSI-0. In IDDSI-0, SpO2 decrease significantly correlated with aspiration (p = 0.0001). In IDDSI-4, 20.5% had SpO2 decrease without aspiration, and showing no significant difference (p = 0.613). Penetration-Aspiration Scale scores had no significant association with SpO2 decrease (p = 0.602). Pulse oximetry in IDDSI-4 had limited sensitivity (0%) and positive predictive value, (0%) while in IDDSI-0, it demonstrated acceptable sensitivity (60.9%) and specificity (100%) with good discrimination capability (AUC = 0.83). CONCLUSIONS: A decrease in SPO2 may indicate potential aspiration but is insufficient alone for detection. This study proposes pulse oximetry as a valuable complementary tool in assessing dysphagia but emphasizes that aspiration cannot be reliably predicted based solely on SpO2 decrease.

RESUMEN

OBJECTIVE: The purpose of this study is to examine vocal fatigue and impairment, gastroesophageal symptoms, dysphagia risk, and sleep-related quality of life in individuals with obstructive sleep apnea (OSA) who have been treated with continuous positive airway pressure (CPAP) compared to those who have not received treatment. METHODS: Fifty-four participants diagnosed with OSA completed an online research form. Of these, 29 were receiving CPAP treatment, while 25 were not undergoing treatment. The following instruments were used: Vocal Fatigue Index, Voice Handicap Index, Gastroesophageal symptoms, Eating Assessment Tool, and Quebec Sleep Questionnaire. RESULTS: The group that received CPAP treatment had significantly lower scores in the functional domain and total Voice Handicap Index. They also experienced fewer symptoms of regurgitation, reduced daytime sleepiness, fewer nocturnal symptoms, and better emotional and social interactions in their quality of life compared to the untreated group. There were no significant differences in voice fatigue and dysphagia risk between the groups. CONCLUSION: Individuals treated with CPAP experience reduced vocal impairment, fewer regurgitation symptoms, and improvement in the emotional and social interactions domains of their quality of life compared to individuals without treatment.

RESUMEN

Background: Oropharyngeal dysphagia (OD) significantly impacts older individuals and neurologically compromised patients, hindering safe ingestion of food and liquids. Despite its prevalence, OD remains underdiagnosed and undertreated, leading to severe complications such as malnutrition, dehydration, respiratory infections, and aspiration pneumonia (AP), and increases hospital readmissions. Objectives: This study analyzes the intricate relationship between OD and various clinical complications in older individuals and patients with neurological disorders. Methods: Utilizing retrospective analysis and narrative review, our work consolidates findings from prior studies on Hospital de Mataro's dysphagia patient cohort. Revisiting OD's intricate association with clinical complications, it presents data via odds ratios (OR), incidence ratios (IR), and hazard ratios (HR) from univariate and multivariate analyses. Results: Five studies (2001-2014) involving 3,328 patients were scrutinized. OD exhibited independent and significant associations with various complications among older patients. Older individuals with OD faced heightened 1-month (ODDS 3.28) and 1-year (OR 3.42) mortality risks post-pneumonia diagnosis. OD correlated with a 2.72-fold risk of malnutrition, 2.39-fold risk of lower respiratory tract infections, 1.82-fold pneumonia readmissions (IR), and 5.07-fold AP readmissions (IR). Post-stroke OD is linked to neurological impairment (OR 3.38) and respiratory (OR 9.54) and urinary infections (OR 7.77), alongside extended hospital stays (beta coefficient 2.11). Conclusion: Oropharyngeal dysphagia causes and significantly exacerbates diverse clinical complications in older and post-stroke patients, emphasizing the urgent need for proactive identification, comprehensive assessment, and tailored management. Acknowledging OD's broader implications in general medical practice is pivotal to improving patient outcomes and healthcare quality.

RESUMEN

Eosinophilic esophagitis (EoE) is a chronic inflammatory condition of the esophagus that affects both children and adults. Symptoms in adults are mainly esophageal dysphagia, which ranges from mild symptoms to acute food bolus obstruction of the esophagus. Diagnosis is defined as symptoms of esophageal dysfunction and ≥ 15 eosinophils/high power field (HPF) in at least one of the biopsies taken from the esophagus. EoE appears to be increasing in both prevalence and incidence. The aim of this study was to investigate the prevalence, incidence, and presenting symptoms of patients with EoE within the catchment area of Northern Älvsborg County Hospital in Trollhättan. Patient records with the ICD code of EoE between 2012 and 2022 and pathology reports from esophageal biopsies from 2000-2022 were examined. Patients with symptoms of esophageal dysfunction and > 15 eosinophils/HPF were classified as having EoE. In total, 409 EoE patients (379 adults and 30 children) fulfilled the diagnostic criteria during the follow-up period. The overall prevalence was 113 cases/100 000 inhabitants (adults 127/100 000 and children 57/100 000) at 31 December 2022. The incidence was 7/100 000 and increased during the observation period. At diagnosis, 46% of the adults and 11% of the children had a history of acute bolus obstruction requiring hospitalization, while 51% of adults and 22% of children exhibited endoscopic findings of fibrosis. The prevalence of EoE is significantly higher than that generally reported in an area of southwest Sweden. The results indicate that the incidence is increasing; however, whether this is due to an actual increase or heightened awareness of EoE is inconclusive. Acute bolus obstruction is a common presenting symptom among EoE patients and is most likely an effect of late diagnosis.

RESUMEN

BACKGROUND: The Gugging Swallowing Screen (GUSS) is a bedside dysphagia screening tool that has been designed to determine the risk of aspiration in acute stroke patients. There is no evidence in the literature for the GUSS for the pediatric population. The present study aimed to determine the diagnostic accuracy of GUSS as a screening tool in the Greek language for children with dysphagia. METHODS: Eighty-Greek-Cypriot children aged 3-12 years who had dysphagia participated in this retrospective study. The translated into Greek GUSS was administered twice (pre- and post-therapy) to each patient throughout 24 sessions of dysphagia therapy. KEY RESULTS: The GUSS showed a high internal consistency (Cronbach's α = 0.826), good test-retest reliability (rs = 0.767), convergent validity compared to the Greek Pediatric Eating Assessment tool-10 (PEDI-EAT-10) total score (rs = -0.365), and inter-rater reliability (κ = 0.863). A total cutoff points equal to 13.00 was also calculated. Aspiration was identified by the GUSS with low sensitivity and high specificity (PPV 100%, NPV 57%, LR+ NA, LR- 0.79); dysphagia/penetration was identified with high sensitivity and low specificity (PPV 33%, NPV 100%, LR+ 0.102, LR- NA). CONCLUSIONS & INFERENCES: The pediatric version of GUSS has been found to be a valuable tool in identifying the risk of aspiration as that of adults. It proved to be used as a good screening guide for selecting and confirming the existence of dysphagia from instrumental assessments. This is the first study of the pediatric version of GUSS, and future studies on this topic are needed.
