Manometría de alta resolución con impedancia para el estudio de la motilidad faríngea y del esfínter esofágico superior: claves para su utilización en el estudio de la fisiopatología de la disfagia orofaríngea / High-resolution manometry with impedance for the study of pharyngeal motility and the upper esophageal sphincter: Keys for its use in the study of the pathophysiology of oropharyngeal dysphagia

La disfagia orofaríngea (DO) es una enfermedad con una alta prevalencia en diferentes fenotipos de pacientes. La manometría de alta resolución faringoesofágica (MARFE) con impedancia (MARFE-I) se ha convertido en los últimos años en una técnica fundamental para el mejor entendimiento de la fisiopatología de las disfunciones de la faringe y del esfínter esofágico superior (EES) en pacientes con DO. Diversos grupos de expertos han propuesto una metodología para la práctica de la MARFE-I y para la estandarización de las diferentes métricas para el estudio de las disfunciones de la motilidad faríngea y del EES basadas en el la cuantificación de 3fenómenos principales: la relajación del EES, la resistencia al flujo a través del EES y la propulsión del bolo a través de la faringe hacia el esófago. De acuerdo a las alteraciones de estas métricas, se proponen 3patrones de disfunción que permiten un abordaje terapéutico específico: a) restricción al flujo del EES con propulsión faríngea normal; b) restricción al flujo del EES con propulsión faríngea inefectiva, y c) contracción faríngea inefectiva con normal relajación del EES. Presentamos una revisión práctica de la metodología y la métrica que emplean los principales grupos de trabajo junto con la descripción de los principales patrones de disfunción de acuerdo con nuestra experiencia para poner de relevancia la utilidad de la MARFE-I en el estudio de la fisiopatología y selección de un tratamiento específico en pacientes con DO.

Oropharyngeal dysphagia (OD) is a pathology with a high prevalence in different patient phenotypes. High-resolution pharyngoesophageal manometry (HRPM) with impedance (HRPM-I) has become in recent years a fundamental technique for better understanding the pathophysiology of pharynx and upper oesophageal sphincter (UES) dysfunctions in patients with OD. Various groups of experts have proposed a methodology for the practice of the HRPM-I and for the standardization of the different metrics for the study of pharyngeal motility and UES dysfunctions based on the quantification of 3main phenomena: relaxation of the UES, resistance to flow through the UES and propulsion of the bolo through the pharynx into the oesophagus. According to the alterations of these metrics, 3patterns of dysfunction are proposed that allow a specific therapeutic approach: (a) UES flow restriction with normal pharyngeal propulsión; (b) UES flow restriction with ineffective pharyngeal propulsion, and (c) ineffective pharyngeal contraction with normal relaxation of the UES. We present a practical review of the methodology and metrics used by the main working groups together with the description of the main patterns of dysfunction according to our experience to highlight the usefulness of the HRPM-I in the study of the pathophysiology and selection of a specific treatment in patients with OD.

Dysphagia and Lung Disease in Children With Spinal Muscular Atrophy Treated With Disease-Modifying Agents.

OBJECTIVES: Disease-modifying agents (DMAs) for the treatment of spinal muscular atrophy (SMA) have evolved the SMA phenotype with improved survival. Ongoing oropharyngeal dysphagia and respiratory complications are reported. The extent of dysphagia and respiratory morbidity in this population, since DMAs' introduction, has not been well described. METHODS: A whole-population study involved all children with treated SMA types 1-3 in our facility. Videofluoroscopic swallow studies (type 1 alone), chest CT scans, and clinical data were collected. RESULTS: Thirty-six children were included (n = 9 type 1, n = 14 type 2, and n = 13 type 3; age range 0.3-15.4 years). Abnormal swallowing characteristics were demonstrated in all children with type 1 (n = 8; 100%). Bronchiectasis was found on chest CT: 3 of 9 (33.3%), 2 of 14 (14.3%), and 2 of 13 (15.4%) of type 1, 2, and 3, respectively. Atelectasis, mucus plugging, bronchial wall thickening, and parenchymal changes were common. DISCUSSION: Swallow impairments were universal in children with type 1. Bronchiectasis was common in all pediatric SMA types, with a prevalence of 1 in 5. Routine monitoring and management of dysphagia/recurrent respiratory infection should be implemented for improvement in lung health.

Optogenetic stimulation of pre-Bötzinger complex reveals novel circuit interactions in swallowing-breathing coordination.

The coordination of swallowing with breathing, in particular inspiration, is essential for homeostasis in most organisms. While much has been learned about the neuronal network critical for inspiration in mammals, the pre-Bötzinger complex (preBötC), little is known about how this network interacts with swallowing. Here we activate within the preBötC excitatory neurons (defined as Vglut2 and Sst neurons) and inhibitory neurons (defined as Vgat neurons) and inhibit and activate neurons defined by the transcription factor Dbx1 to gain an understanding of the coordination between the preBötC and swallow behavior. We found that stimulating inhibitory preBötC neurons did not mimic the premature shutdown of inspiratory activity caused by water swallows, suggesting that swallow-induced suppression of inspiratory activity is not directly mediated by the inhibitory neurons in the preBötC. By contrast, stimulation of preBötC Dbx1 neurons delayed laryngeal closure of the swallow sequence. Inhibition of Dbx1 neurons increased laryngeal closure duration and stimulation of Sst neurons pushed swallow occurrence to later in the respiratory cycle, suggesting that excitatory neurons from the preBötC connect to the laryngeal motoneurons and contribute to the timing of swallowing. Interestingly, the delayed swallow sequence was also caused by chronic intermittent hypoxia (CIH), a model for sleep apnea, which is 1) known to destabilize inspiratory activity and 2) associated with dysphagia. This delay was not present when inhibiting Dbx1 neurons. We propose that a stable preBötC is essential for normal swallow pattern generation and disruption may contribute to the dysphagia seen in obstructive sleep apnea.

Growth in infants, children and adolescents with unilateral and bilateral cerebral palsy.

To compare growth patterns during infancy, childhood and adolescence in children with unilateral and bilateral cerebral palsy (CP) phenotype and to assess the association with gross motor impairment, dysphagia and gestational age. We retrospectively studied 389 children with CP from a single center population in Munich, Germany. 1536 measurements of height and weight were tabulated and z-scored from 6 to 180 months of age. Generalized linear mixed model were used to examine the association between growth, GMFCS, dysphagia and gestational age by CP phenotype. Children with unilateral CP tend to grow similarly to their typically developed peers. In the main effect model, bilateral CP phenotype was significantly associated with decreased mean z-scores for height (ß [95% CI] - 0.953 [- 1.145, - 0.761], p < 0.001), weight (- 0.999 [- 1.176, - 0.807], p < 0.001) and BMI (ß [95% CI] - 0.437 [- 0.799, - 0.075]), compared with unilateral CP phenotype. This association remained significant in the interaction models. The height-for-age z-scores, weight-for-age decreased z-scores and BMI-for-age z-scores of children with bilateral CP and GMFCS III-V or dysphagia decreased more significantly than those of children with unilateral CP. Preterm birth was not significantly associated with decreased growth in height, weight and BMI. Reduced growth in children with bilateral CP was strongly associated with moderate to severe impairment in gross motor function (GMFCS III-V) and dysphagia.

A simplified method for evaluating swallowing ability and estimating malnutrition risk: A pilot study in older adults.

OBJECTIVES: The aim of this pilot study was to develop a Thai-version of a simple swallowing questionnaire, called the T-SSQ, and to evaluate the association between malnutrition risk and swallowing ability, determined objectively by tongue strength and subjectively by the T-SSQ. Sensitivity analysis was also performed to determine which swallowing indices better estimate malnutrition in older adults. METHODS: This cross-sectional study comprised two phases: Phase I, development and cross-cultural translation of the T-SSQ; and Phase II, application of the T-SSQ in 60 older adults. In Phase I, content and face validity of the T-SSQ was evaluated by 10 experts and 15 older adults. In Phase II, the convergent validity of the T-SSQ was evaluated by determining its association with objective tongue strength. Nutritional status was evaluated using the Thai-version of the Mini-Nutritional Assessment. Covariates included sociodemographic characteristics, and oral and health-related status. Adjusting for covariates, the associations between the two swallowing indices and malnutrition risk were determined using multivariable regression analyses. A cut-off value for low tongue strength was determined using a receiver operating characteristic (ROC) curve, and sensitivity analysis between the swallowing indices and malnutrition risk was performed. RESULTS: The T-SSQ comprised 4-items of common signs and symptoms of a swallowing problem. Its content and face validity were verified. Older adults were considered as having a swallowing problem when at least one item was reported. Convergent validity of the subjective index was shown by significantly different tongue strength values between the participants with and without a swallowing problem (p for independent t-test = 0.014). Based on the highest area under the ROC curve, an 18-kPa cut-off value was chosen to classify low tongue strength. Having a swallowing problem and low tongue strength was significantly associated with malnutrition risk. The positive predictive value of the subjective swallowing index was 1.8-fold higher than objective tongue strength. CONCLUSIONS: Self-reported swallowing problems determined by the T-SSQ can be used as a subjective index for evaluating swallowing ability in older adults. Subjective swallowing problems and objective tongue strength were associated with malnutrition risk. However, the T-SSQ estimated malnutrition risk better than the objective index.

Swallowing kinematic analysis might be helpful in predicting aspiration and pyriform sinus stasis.

Aspiration due to dysphagia can lead to aspiration, which negatively impacts a patient's overall prognosis. Clinically, videofluoroscopic swallow study (VFSS) is considered the gold-standard instrument to determine physiological impairments of swallowing. According to previously published literature, kinematic analyses of VFSS might provide further information regarding aspiration detection. In this study, 449 files of VFSS studies from 232 patients were divided into three groups: normal, aspiration, and pyriform sinus stasis. Kinematic analyses and between-group comparison were conducted. Significant between-group differences were noted among parameters of anterior hyoid displacement, maximal hyoid displacement, and average velocity of hyoid movement. No significant difference was detected in superior hyoid displacement. Furthermore, receiver-operating characteristic (ROC) analyses of anterior hyoid displacement, velocity of anterior hyoid displacement, and average velocity of maximal hyoid displacement showed acceptable predictability for detecting aspiration. Using 33.0 mm/s as a cutoff value of average velocity of maximal hyoid displacement, the sensitivity of detecting the presence of aspiration was near 90%. The investigators therefore propose that the average velocity of maximal hyoid displacement may serve as a potential screening tool to detect aspiration.

Gastrointestinal Dysfunction in Parkinson's Disease.

There has been exponential growth in the awareness and understanding of gastrointestinal (GI) dysfunction in Parkinson's disease (PD) over the past 3 decades. The clinical features of GI dysfunction in PD have been clearly identified and innovative research has demonstrated the presence of pathology within the enteric nervous system (ENS) in individuals with PD, leading to suggestions that the GI system may be ground zero for the genesis and the portal of entry of PD pathology, which then ascends via the vagus nerve to the central nervous system (CNS). This theory, as well as the more recent recognition of the association of PD with dysbiosis within the gut microbiota, has been the object of intense study and scrutiny. Since most PD medications are absorbed through the GI system, the need for better understanding of changes within the GI tract that may potentially affect the pattern of response to medications has become evident. In this review, current knowledge of the pathophysiology of changes within the GI tract and the gut microbiome of individuals with PD, including changes that occur with progression of the disease, will be addressed. We focus on common clinical GI problems in PD that can arise from different segments of the GI tract. Relevant diagnostic evaluations and treatment options for each of these problems will be reviewed.

A study of acoustic characteristics of voluntary expiratory sounds produced before and immediately after swallowing.

To evaluate the expiratory sounds produced during swallowing recorded simultaneously with videofluorographic examination of swallowing (VF) using fast Fourier transform (FFT), and to examine the relationship between dysphagia and its acoustic characteristics. A total of 348 samples of expiratory sounds were collected from 61 patients with dysphagia whose expiratory sounds were recorded during VF. The VF results were evaluated by one dentist and categorized into three groups: safe group (SG), penetration group (PG), and aspiration group (AG). The duration and maximum amplitude of expiratory sounds produced were measured as the domain characteristics on the time waveform of these sounds and compared among the groups. Time window-length appropriate for FFT and acoustic discriminate values (AD values) of SG, PG, and AG were also investigated. The groups were analyzed using analysis of variance and Scheffé's multiple comparison method. The maximum amplitude of SG was significantly smaller than those of PG and AG. The mean duration in SG (2.05 s) was significantly longer than those in PG (0.84 s) and AG (0.96 s). The AD value in SG was significantly lower than those in PG and AG. AD value detects penetration or aspiration, and can be useful in screening for dysphagia.

Dysphagia limit in children with cerebral palsy aged 4 to 12 years.

AIM: To assess the dysphagia limit in children with cerebral palsy (CP) according to Eating and Drinking Ability Classification System (EDACS) level, sex, and age compared to typically developing children. METHOD: Seventy-seven children with CP (54 males, 23 females; mean age 7y 6mo, SD 2y 2mo, age range 4-12y) were assessed with the Maximum Volume Water Swallow Test. Median dysphagia limit in the CP group was compared with data of typically developing children. RESULTS: The dysphagia limit of children with CP differed significantly (p<0.001) from typically developing children. The latter showed a threefold higher median dysphagia limit (22mL) compared to children with CP in EDACS level I (7mL). The higher the EDACS level, the lower the dysphagia limit in children with CP. EDACS level explained 55% of the variance in the dysphagia limit of the CP group. INTERPRETATION: Where children with CP in EDACS levels IV and V showed that their capacity met the level of their performance, children in EDACS level I had the ability to perform a maximum capacity task, but still had a threefold lower median dysphagia limit than typically developing children. Establishment of the dysphagia limit should be part of general swallowing assessment in children with CP.

Aesthesiometer-Based Testing for Laryngopharyngeal Hyposensitivity.

OBJECTIVES/HYPOTHESIS: To develop a method for threshold estimation of the laryngeal adductor reflex (LAR) response using Cheung-Bearelly monofilaments. STUDY DESIGN: Cross-sectional. METHODS: Twenty-two healthy adults (12 men, 10 women) were tested for LAR response outcome using 30 mm 5-0 and 4-0 nylon monofilaments. Tactile stimuli were delivered to the aryepiglottic (AE) fold and medial pyriform sinus (MPS). Dichotomous classifier features and performance (area under the curve (AUC)), the LAR response outcome agreement and disagreement matrix, and test-retest reliability were examined. From those data, a test protocol that would minimize patient burden to estimate the LAR triggering threshold was formulated. RESULTS: Classifier performance of 5-0 monofilament stimulation of the AE fold (sensitivity = 0.63, specificity = 0.63, PPV = 0.74, NPV = 0.25) and MPS (sensitivity = 0.45, specificity = 0.77, PPV = 0.74, NPV = 0.23,) was slightly below that of 4-0 monofilament stimulation of the AE fold (sensitivity = 0.82, specificity = 0.50, PPV = 0.82, NPV = 0.50) and MPS (sensitivity = 0.84, specificity = 0.64, PPV = 0.90, NPV = 0.56), based on AUC. LAR response outcome agreement for 5-0 and 4-0 stimulations was high (93%) for 5-0 positive response, but low (29%) for 5-0 negative response. Aesthesiometer test-retest reliability for LAR response outcome was excellent (Cronbach's alpha = 0.97). CONCLUSIONS: Threshold estimation of the LAR response may be operationalized by adopting a decision tree protocol. For negative LAR response to initial 5-0 monofilament stimulation and positive response to subsequent 4-0 monofilament stimulation, the higher threshold is confirmed. Positive LAR response to 5-0 or 4-0 monofilament stimulation is expected in over 90% of asymptomatic adults. Negative LAR response to 4-0 monofilament stimulation identifies patients at risk for laryngopharyngeal hyposensitivity. LEVEL OF EVIDENCE: 3b Laryngoscope, 132:163-168, 2022.

Reduced masticatory function predicts gastroesophageal reflux disease and esophageal dysphagia in patients referred for upper endoscopy: A cross-sectional study.

BACKGROUND: The role of mastication on gastroesophageal reflux disease (GERD) is unknown. AIMS: To assess whether reduced masticatory function predicts GERD and esophageal dysphagia in patients investigated with upper endoscopy. METHODS: In this cross-sectional study, 179 adult patients referred for elective upper gastrointestinal endoscopy agreed to participate. Before endoscopy, an expert dentist performed an oral examination and scored chewing function in three levels (normal, regular, and reduced). Patients replied questionnaires for assessment of GERD (heartburn, regurgitation, and dysphagia), xerostomia, and mastication (normal, regular, and reduced). Poor chewing was defined when either oral examination or mastication questionnaire rated the chewing function as reduced. Associations of mastication with GERD and dysphagia were estimated using Poisson regression. RESULTS: Eleven patients were excluded. Among 168 analyzed (aging 49.8 ± 15.5 years; 58.9% women), 46 had reduced masticatory function (27.4%), and 122 had regular/normal mastication (72.6%). Reduced mastication was associated with GERD [PR = 1.38 (95%CI 1.12 - 1.70)], adjusting for age, and with esophageal dysphagia [PR = 2.03 (95%CI 1.02 - 4.04)], adjusting for age and xerostomia. CONCLUSIONS: In outpatients referred for upper gastrointestinal endoscopy, reduced masticatory function defined by an expert dentist may be a risk factor for GERD and esophageal dysphagia.

Associação entre o número de deglutições, resíduo faríngeo e broncoaspiração na esclerose múltipla / Association between the number of swallowing, pharyngeal residue and bronchopulmonary aspiration in multiple sclerosis

RESUMO Objetivo verificar a associação entre o número de deglutições e presença de resíduo faríngeo e broncoaspiração em pessoas com esclerose múltipla. Métodos estudo transversal observacional de exames de videofluoroscopia de 231 deglutições de indivíduos com esclerose múltipla. Três fonoaudiólogas avaliaram as deglutições de IDDSI 1 (International Dysphagia Diet Standardisation Initiative) (5 ml e 10 ml) e IDDSI 4 (8 ml) quanto à presença de resíduo faríngeo e de penetração/aspiração. Deglutições que não apresentaram resíduo faríngeo foram classificadas como deglutições sem resíduos faríngeos (DSR) e as que apresentaram, como deglutições com resíduos faríngeos (DCR), sendo estas últimas subdivididas em resíduos faríngeos em todas as ofertas ou eventuais (DCR1 e DCR2). O número de deglutições foi analisado por um avaliador cego e comparado com os dados demográficos e clínicos. Resultados das 231 deglutições, 73 (31,6%) apresentaram resíduos faríngeos. O número médio de deglutições foi semelhante nas deglutições sem e com resíduos faríngeos em cada consistência e volume e nas variáveis idade, gênero, tipo de esclerose múltipla e incapacidade funcional. Houve associação entre a média do número de deglutições e a ausência de penetração/aspiração, quando comparada às deglutições sem e com resíduos faríngeos, nas DCR2 e em indivíduos acima de 50 anos. Ao analisar intragrupo, observou-se associação nas DCR, sendo maior na ausência de penetração/aspiração e nas DCR2. Conclusão não houve correlação entre o número de deglutições e a presença de resíduos em recessos faríngeos na esclerose múltipla. Todavia, o número de deglutições foi maior quando houve resíduo e ausência de disfagia e de penetração/aspiração, em indivíduos mais velhos.

ABSTRACT Purpose To verify the association between the number of swallows and the presence of pharyngeal residue and bronchoaspiration in people with Multiple Sclerosis. Methods An observational cross-sectional study of videofluoroscopic examinations of 231 swallows from individuals with Multiple Sclerosis. Three speech therapists evaluated IDDSI 1 (International Dysphagia Diet Standardisation Initiative) (5ml and 10ml) and IDDSI 4 (8ml) deglutitions for pharyngeal residue and penetration/ aspiration. Swallows with no pharyngeal residue were classified as swallows without pharyngeal residue (SWTR) and those with pharyngeal residue (SWR), the latter subdivided into pharyngeal residue in all or occasional offerings (SWR1 e SWR2). The number of swallows was analyzed by a blind evaluator and compared with demographic and clinical data. Results Of the 231 swallows, 73 (31.6%) showed pharyngeal residues. The mean number of swallows was similar in the deglutitions with and without pharyngeal residues in each consistency and volume and in the variables age, gender, type of Multiple Sclerosis and functional disability. There was an association between the mean number of swallows and the absence of penetration/aspiration when comparing deglutitions with and without pharyngeal residues, in SWR2 and in individuals over 50 years of age. When analyzing intragroup, an association was observed in SWR, being higher in the absence of penetration/aspiration and in SWR2. Conclusion There was no correlation between the number of swallows and the presence of residues in pharyngeal recesses in multiple sclerosis. However, the number of swallows was higher when there was residue and absence of dysphagia and penetration/aspiration, and in older individuals.

Deglución post extubación de pacientes críticos con y sin diagnóstico de COVID-19 durante la pandemia / Post extubation swallowing in critical patients with and without COVID-19 during the pandemic

Estudios previos han caracterizado la disfagia en pacientes críticos hospitalizados que requieren intubación y ventilación mecánica invasiva. A raíz de la pandemia COVID-19 es necesario conocer las características deglutorias de pacientes diagnosticados con la enfermedad para su manejo. El objetivo de este estudio es analizar las características deglutorias de pacientes críticos extubados con y sin diagnóstico de COVID-19. Se llevó a cabo un estudio de cohorte retrospectivo con una muestra a conveniencia de 43 sujetos mayores de 15 años, ingresados al Hospital San Juan de Dios (Santiago, Chile) entre el 01 de junio y el 31 de agosto de 2020, intubados con o sin diagnóstico de COVID-19. Del total de sujetos, 22 padecieron de COVID-19 quienes estuvieron significativamente más días intubados que aquellos sin la patología (p=0,002). Inmediatamente posterior a la extubación orotraqueal, más del 90% de la muestra presentó disfagia. No hubo diferencia significativa en el nivel FILS ni asociación significativa en el grado de severidad de la disfagia entre sujetos con y sin COVID-19. Tampoco hubo diferencia significativa en el nivel FILS entre los grupos a los 10 días post-extubación. El nivel FILS a los 10 días aumentó significativamente en aquellos sujetos con COVID-19 (p=0,016) y sin COVID-19 (p=0,004). En la muestra, el nivel FILS y grado de severidad de la disfagia de los pacientes con y sin COVID-19 no mostraron diferencias estadísticas, siendo alto el porcentaje de disfagia en ambos grupos, lo que se podría asociar a la intubación orotraqueal y al tubo orotraqueal. Es necesaria la incorporación del fonoaudiólogo dentro de los equipos de Unidades de Pacientes Críticos para el manejo de los pacientes con COVID-19 y disfagia. Además, se recomienda continuar con más estudios en el área.

Previous research have described the deglutition disorders in critical hospitalised patients who required intubation and mechanical ventilation. In the pandemic context, it is mandatory to study both level and grade of dysphagia in patients suffering from COVID-19. The aim of this study is to analyse the deglutition features of extubated critical patients with and without COVID-19. A retrospective cohort study was performed, considering a convenience sample of 43 patients from 15 years old hospitalised at 'Hospital San Juan de Dios' between June 1st and August 31th 2020, who were intubated, with and without the diagnosis of COVID-19. 22of out 43 patients were diagnosed with COVID-19 who were intubated for significantly more days in comparison with those without COVID-19 (p=.002). After the intratracheal extubation, 90% of the sample was diagnosed with dysphagia. There was no significant difference in the FILS score nor significant association in dysphagia severity between patients with and without COVID-19. After 10 days post extubation, there was no significant difference in the FILS score between both groups. The FILS score increased significantly in the COVID-19 (p=.016) and non-COVID-19 (p=.004) patients after 10 days post extubation. Post extubation, there are no statistical differences in the FILS score and dysphagia severity in critical ill patients with and without COVID-19, with a high percentage of dysphagia in both groups which could be associated with intratracheal intubation and endotracheal tubes. The incorporation of speech and language therapists in Critical Care Units is mandatory. Furthermore, it is recommended to perform extra research in the area.

RESUMO Objetivo verificar as evidências disponíveis sobre o efeito dos exercícios vocais no tratamento da disfagia. Estratégia de pesquisa foi realizado levantamento bibliográfico nas bases de dados PubMed, LILACS, SciELO e MEDLINE, sem restrições quanto ao período de publicação. Critérios de seleção artigos originais, estudos de caso e/ou revisões de literatura publicados nos idiomas português e/ou inglês, disponíveis eletronicamente na íntegra e que abordassem o tratamento clínico com exercícios vocais em adultos e idosos com disfagia. Foram excluídas publicações repetidas nas bases de dados, com população de crianças, com indivíduos que não apresentassem o diagnóstico de disfagia, com exercícios vocais sem especificação, com exercícios exclusivos de deglutição, artigos e/ou resumos sem possibilidade de acesso pelas plataformas institucionais e estudos com modelo animal. Resultados foram encontrados 2.356 artigos, dos quais, após aplicados os critérios de elegibilidade, foram selecionados 8 para a amostra final. Para avaliar os efeitos dos exercícios vocais, os estudos utilizaram avaliação clínica, videofluoroscopia, videoendoscopia e eletromiografia. Quanto aos efeitos dos exercícios vocais na deglutição, observou-se que as técnicas de som plosivo, empuxo, trato vocal semiocluído, som basal, modulação vocal, sobrearticulação, o método Lee Silverman Voice Treatment® e o uso de exercícios de treino de força muscular expiratória apresentaram efeitos positivos na reabilitação da disfagia. Conclusão os estudos com treino de força muscular expiratória, o método Lee Silverman e os exercícios vocais tradicionais demonstraram efeitos positivos no tratamento da disfagia. No entanto, ainda não foi possível comprovar o nível de evidências de todos os estudos.

ABSTRACT Purpose To verify the available evidence on the effect of vocal exercises on the treatment of dysphagia. Research strategy A bibliographic survey was carried out in the PubMed, LILACS, SciELO and MEDLINE databases, with no restrictions on the publication period. Selection criteria Original articles, case studies and/or literature reviews published in Portuguese and/or English, available electronically in full and addressing clinical treatment with vocal exercises in adults and elderly with dysphagia. Publications repeated by the databases, with a population of children, individuals who did not present the diagnosis of dysphagia, with vocal exercises without specification, with exclusive swallowing exercises, articles and/or abstracts without the possibility of access by institutional platforms, and studies with animal model were excluded. Results A total of 2,356 articles were found, of which, after the eligibility criteria were applied, 08 were selected for the final sample. To evaluate the effects of vocal exercises, the studies used clinical evaluation, videofluoroscopy, videoendoscopy and electromyography. Regarding the effects of vocal exercises on swallowing, it was observed that the techniques of plosive sound, buoyancy, semi-occluded vocal tract, basal sound, vocal modulation, overarticulation, the Lee Silverman Voice Treatment method® and the use of expiratory muscle strength training exercises showed positive effects in the rehabilitation of dysphagia. Conclusion It was observed that studies with expiratory muscle strength training (EMST), Lee Silverman method (LSVT®) and traditional vocal exercises demonstrated positive effects in the treatment of dysphagia. However, it has not yet been possible to prove the level of evidence in all studies.

Patients with Post-Covid-19 Syndrome are at risk of malnutrition and obesity: findings of outpatient follow-up / Pacientes com Síndrome Pós-Covid-19 apresentam risco de desnutrição e obesidade: achados de um ambulatório de seguimento

ABSTRACT Objective To evaluate the nutritional and functional status, swallowing disorders, and musculoskeletal manifestations of patients with Post-Covid-19 Syndrome, stratified by the Appendicular Skeletal Muscle Mass Index. Methods This is a cross-sectional study with patients diagnosed with Post-Covid-19 Syndrome after discharge from the intensive care unit of a university hospital. The evaluated outcomes were: nutritional status (Mini Nutritional Assessment, bioimpedance and anthropometry), swallowing disorders (Dysphagia Risk Evaluation Protocol), functional status (Post-Covid-19 Functional Status Scale), and musculoskeletal manifestations. According to the Appendicular Skeletal Muscle Mass Index, patients were stratified in terms of loss or not loss of muscle mass. Results Thirty-eight patients were included in the study, 20 stratified into the no loss of muscle mass group (17 females; 49.45±12.67 years) and 18 into the loss of muscle mass group (18 males; 61.89±12.49 years). Both groups were at risk of malnutrition (Mini Nutritional Assessment scores between 17-23.5 points; No Loss of Muscle Mass Group: 21.82±3.93; Loss of Muscle Mass Group: 23.33±3.41) and obesity (No Loss of Muscle Mass Group: 33.76±6.34; Loss of Muscle Mass Group: 30.23±3.66). The groups differed in terms of bioimpedance parameters (except fat mass) and age. However, there were no differences in swallowing alterations, functional status, and musculoskeletal manifestations. Conclusion Patients with Post-Covid-19 Syndrome, stratified according to the Appendicular Skeletal Muscle Mass Index, were at risk of malnutrition and obesity. The persistence of fatigue, weakness, myalgia and arthralgia at 6 months after hospital discharge is noteworthy. These findings emphasize the importance of comprehensive care for patients with Post-Covid-19 Syndrome.

Resultados Foram inseridos no estudo 38 pacientes, 20 no grupo sem perda de massa muscular (17 deles do sexo feminino; 49,45±12,67 anos) e 18 no grupo com perda de massa muscular (todos do sexo masculino; 61,89±12,49 anos). Os pacientes de ambos os grupos apresentaram risco de desnutrição (escores Mini Avaliação Nutricional entre 17-23.5 pontos; Grupo Sem Perda de Massa Muscular: 21,82±3,93; Grupo Com Perda de Massa Muscular: 23,33±3,41) e obesidade (Grupo Sem Perda de Massa Muscular: 33,76±6,34; Grupo Com Perda de Massa Muscular: 30,23±3,66). Os grupos diferiram quanto aos parâmetros da bioimpedância (exceto massa gorda) e idade. Entretanto, não foram observadas diferenças na deglutição, status funcional e manifestações musculoesqueléticas. Conclusão Os pacientes com Síndrome Pós-Covid-19, estratificados conforme o Índice de Massa Muscular Esquelética Apendicular, apresentaram risco de desnutrição e obesidade. Destaca-se a persistência de fadiga, fraqueza, mialgia e artralgia após seis meses da alta hospitalar. Esses achados ressaltam a importância do cuidado integral ao paciente com a Síndrome Pós-Covid-19.
