Oropharyngeal Swallowing Dynamic Findings in People with Asthma.

Airflow obstruction in people with asthma, similar to COPD, may interfere with swallowing, increasing the risk of food or liquid entrance into the lower airways, and favoring the uncontrolled disease. To describe the complaints and findings of the oropharyngeal swallowing mechanisms in patients with mild and severe asthma, a cross-sectional study was performed. A total of 135 participants with asthma were studied, of whom 97 had severe asthma and 38 had mild asthma. All subjects answered a questionnaire with demographic information, disease exacerbations, Asthma Control Questionnaire 6 (ACQ6-Juniper 1999), GastroEsophageal Reflux Disease Symptoms Questionnaire (GERD-SQ-Fornari et al. 2004), and Eating Assessment Tool 10 (EAT-10-Gonçalves et al., 2013). The oral and pharyngeal swallowing assessment occurred via videofluoroscopic swallowing evaluation. The age range of the participants was from 19 to 80 years, with a predominance of females (78.6%). Uncontrolled asthma was observed in 50 (52%) of the patients with severe asthma and in 11 (29%) of the patients with mild asthma (ACQ6 > 1.5). The GERD-SQ and EAT-10 scores were similar in both groups. In the bivariate analysis, the group with severe asthma presented with more changes when compared to the group with mild asthma in the following events: atypical lingual movement during the swallowing of liquid in the volumes of 5 ml (p = 0.003) and 10 ml (p = 0.001), and solid (p = 0.009); oral transit time increased in swallowing of liquid in the volumes of 5 ml (p = 0.003) and 20 ml (p = 0.026); beginning of the pharyngeal swallowing phase below the mandibular ramus (p = 0.003); pharyngeal residue (p = 0.017) of solid consistency; laryngeal penetration of 5 ml (p = 0.050) and 20 ml (p = 0.032) of liquid; increased transition time between the oral and pharyngeal swallowing phases (p = 0.035) and increased pharyngeal transit time (p = 0.045) of solid consistency. Tracheal aspiration was observed only in the group with severe asthma. After the multivariate analysis, atypical tongue movement maintained a statistically significant difference between the two groups. Oropharyngeal swallowing alternations were frequent in the studied sample and more markedly present in patients with severe asthma. Multivariate regression revealed atypical lingual movement, which was greater in patients with severe asthma. The clinical significance of these findings should be further investigated.

Biopsychosocial factors associated with the frailty and pre-frailty among older adults.

Frailty is a multidimensional geriatric syndrome associated with specific biopsychosocial factors in each population. This was a cross-sectional observational study designed to determine the biopsychosocial factors associated with frailty and pre-frailty in older adults in a community in Salvador, Brazil. The stages of frailty were collected in 413 older adults: 34.9% frail, 54.5% pre-frail, 10.6% robust. In the multinomial regression model, age (p = .018), functionality for instrumental activities of daily living (p = .026), risk for falls (p = .006), family functionality (p = .031) and the physical domain of quality of life (p = .004) had an independent association with frailty. Risk for falls (p = .004), family functionality (p = .004) and the environment domain of quality of life (p = .037) were independently associated with pre-frailty. The findings provide support to interventions in a way that contributes to prevention or reversal of frailty.

Quality of life and swallowing questionnaire for individuals with Parkinson's disease: development and validation.

BACKGROUND: Individuals with Parkinson's disease (PD) may exhibit some degree of change in swallowing dynamics during the course of the disease. These changes can affect their physical, functional and emotional quality of life. AIMS: To develop a quality of life and swallowing questionnaire for individuals with PD. METHODS & PROCEDURES: The first version of the questionnaire comprised 29 items taken from the accounts of 50 patients treated over a 2-month period at Sarah Hospital in Salvador, Bahia, Brazil. A committee of 10 experts in the field analyzed the content and reduced the questionnaire to 28 questions. The questionnaire was then administered to 140 PD patients and 47 healthy individuals. A factor analysis of the items guided the drafting of the final questionnaire, which consisted of 19 items grouped into four factors, encompassing physical, functional and emotional aspects. A test-retest assessment was conducted with 44 individuals with PD. OUTCOMES & RESULTS: The internal consistency, estimated by the mean of Cronbach's alpha coefficient, varied between 0.71 (domain 3) and 0.94 (domain 1) in the test and between 0.69 (domain 3) and 0.95 (domain 1) in the retest. The correlation coefficient in the test/retest comparison was high and significant, demonstrating that the measurement was stable. A significant difference was observed between the PD group and the comparison group. CONCLUSIONS & IMPLICATIONS: The questionnaire developed is a valid, statistically appropriate and clinically effective self-administered instrument for individuals with PD.

Videofluoroscopic Predictors of Penetration-Aspiration in Parkinson's Disease Patients.

Parkinson's disease (PD) patients show a high prevalence of swallowing disorders and tracheal aspiration of food. The videofluoroscopic study of swallowing (VFSS) allows clinicians to visualize the visuoperceptual and temporal parameters associated with swallowing disorders in an attempt to predict aspiration risk. However, this subject remains understudied in PD populations. Our aim was to identify the predictors of penetration-aspiration in PD patients using the VFSS. Consecutive patients were evaluated using VFSS with different consistencies and volumes of food. A speech-language pathologist measured the type of intra-oral bolus organization, loss of bolus control, bolus location at the initiation of the pharyngeal swallow, the presence of multiple swallows, piecemeal deglutition, bolus residue in the pharyngeal recesses and temporal measures. Scores ≥3 on the penetration-aspiration scale (PAS) indicated the occurrence of penetration-aspiration. Using logistic marginal regression, we found that residue in the vallecula, residue in the upper esophageal sphincter and piecemeal deglutition were associated with penetration-aspiration (odds ratio (OR) = 4.09, 2.87 and 3.83; P = 0.0040, 0.0071 and 0.0009, respectively). Penetration/aspiration occurred only with fluids (both of thin and thick consistency), and no significant differences were observed between fluid types or food volumes. The mechanisms underlying dysphagia and penetration/aspiration in PD patients and indications for further studies are discussed.

Swallowing disorders in Parkinson's disease: impact of lingual pumping.

BACKGROUND: Lingual pumping (LP) is a repetitive, involuntary, anteroposterior movement of the tongue on the soft palate that is executed prior to transferring the food bolus to the pharynx, but we also observed LP when multiple swallows were taken. LP may be associated with rigidity and bradykinesia in patients with Parkinson's disease (PD). This phenomenon tends to be more prevalent in dysphagic PD patients, and its impact on swallowing dynamics remains poorly understood. OBJECTIVE: To evaluate how LP interferes with the oral and pharyngeal phases of the swallowing of foods of different consistencies and volumes. METHODS: We used videofluoroscopy to study the swallowing of 69 PD patients performing 10 swallows of barium mixed with foods of different consistencies and volumes. RESULTS: LP was associated with the unstable intra-oral organization of the bolus, the loss of bolus control, the pharyngeal retention of food and food entering the airway. This abnormal movement was also associated with a shorter oral transit time and was found to be more prevalent with food of thicker consistencies. CONCLUSIONS: LP is associated with swallowing incoordination and with food entering the airway. Preventive measures to minimise the pulmonary or nutritional consequences of this behaviour are necessary.

Wet voice as a sign of penetration/aspiration in Parkinson's disease: does testing material matter?

Wet voice is a perceptual vocal quality that is commonly used as an indicator of penetration and/or aspiration in clinical swallowing assessments and bedside screening tests. Our aim was to describe the clinimetric characteristics of this clinical sign using various fluid materials and one solid food in the Parkinson's disease (PD) population. Consecutive PD individuals were submitted for simultaneous fiberoptic endoscopic evaluation of swallowing (FEES) and voice recording. Speech therapists rated the presence or absence of wetness and other voice abnormalities. Two binary endpoints of FEES were selected for comparison with an index test: low penetration (LP) and low penetration and/or aspiration (LP/ASP). The accuracy of wet voice changed according to the testing material in PD patients. Overall, the specificity of this indicator was better than its sensitivity, and the wafer cookie and yogurt drink yielded the best indices. Our data show that wet voice is clearly indicative of LP or LP/ASP in PD patients in case of positive test. However, in the case of a negative result, the wet voice test should be repeated or combined with other clinical tests to include or exclude the risk of LP or LP/ASP.

Alterations in deglutition in children with congenital Zika virus syndrome.

PURPOSE: To characterize swallowing in children with congenital Zika virus syndrome in comparison to typical children. METHODS: This cross-sectional study enrolled 45 children diagnosed with congenital Zika virus syndrome and 45 others with typical development. Swallowing was evaluated through clinical feeding evaluations Protocolo de Avaliação Clínica da Disfagia Pediátrica and using acoustic swallowing parameters (Doppler sonar). RESULTS: The mean age of children with congenital Zika virus syndrome was 26.69 ± 4.46 months and the mean head circumference was 29.20 ± 1.98 cm. Moderate/severe oropharyngeal dysphagia was found in 32(71.1%) of the children with congenital Zika virus syndrome. Significant differences were found between the groups on clinical evaluation: Children with congenital Zika virus syndrome presented insufficient lip closure 42(93.3%) and altered tonus of the tongue 35(77.8%) and cheeks 34(75.6%). In the children in the comparison group, only 6(13.3%) presented insufficient lip closure and 1(2.2%) had inadequate tongue posture. Changes during swallowing with liquid and spoonable food were not observed in the comparison group. When liquid/food was offered, affected children presented difficulties in sipping movements 14(77.8%) and lip/spoon contact 35(75%). The presence of residual food in the oral cavity after swallowing 38(86.4%) and clinical signs indicative of laryngotracheal penetration/aspiration, such as coughing, gagging and/or labored breathing, were also notable. No differences were found between the groups with regard to the acoustic parameters evaluated instrumentally. CONCLUSION: Children with congenital Zika virus syndrome present alterations in the oral phase of swallowing, as well as clinical signs indicative of pharyngeal phase impairment.

Silent saliva aspiration in Parkinson's disease.

BACKGROUND: Silent laryngeal penetration and silent aspiration (SLP/SA) are common manifestations in Parkinson's disease (PD) patients and are frequently associated with dysphagia. However, little is known about saliva aspiration in this population. OBJECTIVE: We investigated the frequency and characteristics of saliva SLP/SA in PD patients with daily drooling (Group A) and in individuals without PD or daily drooling (Group B). METHOD: Both groups were evaluated by fiberoptic endoscopic evaluation of swallowing (FEES) after dyeing the oral cavity with blue dye. The oropharynx was assessed for the presence of the stasis of saliva, and sensitivity was tested by direct tactile stimuli. RESULTS: PD patients (n = 28) and controls (n = 18) were evaluated. We observed silent aspiration of saliva in 10.7% and silent laryngeal penetration of saliva near the vocal folds in 28.6% of Group A; however, none of these events was observed in Group B. Sensitivity in the epiglottis and posterior wall of the hypopharynx was decreased in 89.2% of Group A and in 33.3% of Group B, whereas in the aryepiglottic folds and interarytenoid area, a decrease in sensitivity was observed in 92.8% and in 44.4% of Groups A and B, respectively. CONCLUSION: Silent aspiration and laryngeal penetration of saliva are common features in PD patients with daily drooling. The presence of hypoesthesia of the laryngeal structures and the lack of protective reflexes in such patients may play a major role in the mechanisms of SLP/SA.

Oral motor disorder and feeding difficulty during the introduction of complementary feeding in preterm infants. / Disfunção motora oral e dificuldade alimentar durante a alimentação complementar em crianças nascidas pré-termo.

PURPOSE: To investigate the association between oral-motor disorder and feeding difficulty during the process of introducing complementary feeding in preterm infants. METHODS: This is a cross-sectional, observational, and quantitative study. Preterm infants who had already begun complementary feeding and were up to 24 months corrected gestational age, were followed up at an outpatient clinic for high-risk newborns. The feeding difficulty was assessed using the mother's perception of the presence of defensive behaviors in their child. The measurement of the oral motor skills performance was obtained through the application of an adaptation of the Clinical evaluation protocol of pediatric dysphagia (PAD-PED). RESULTS: The sample consisted of 62 dyads of children with a mean corrected gestational age (CGA) of 13.5 months. Complementary feeding was introduced at the sixth month CGA by almost half of the mothers and most of them reported some sort of difficulty with this activity. Extreme prematurity revealed an association with defensive feeding behavior (p = 0.005), as well as with the initial introduction of food with liquid consistency (p = 0.001), the extended period of time using enteral tube feeding (p = 0.044), the continuous positive airway pressure (CPAP) (p = 0.013) and parenteral nutrition (p = 0.039). CONCLUSION: There was no significant association between oral motor disorder and feeding difficulty.

OBJETIVO: Investigar a associação entre a disfunção motora oral e a dificuldade alimentar durante o processo de introdução de alimentação complementar em crianças nascidas pré-termo. MÉTODO: Trata-se de um estudo transversal, observacional e quantitativo. Nele, foram incluídos prematuros em acompanhamento em um ambulatório de seguimento de recém-nascidos de alto risco, que já tinham iniciado a alimentação complementar e possuíam até 24 meses de idade gestacional corrigida. A dificuldade alimentar foi investigada mediante a percepção da mãe quanto à presença de comportamentos defensivos do filho. A medida do desempenho das habilidades motoras orais foi obtida a partir da aplicação de uma adaptação do Protocolo de Avaliação Clínica da Disfagia Pediátrica (PAD-PED). RESULTADOS: A amostra foi composta por 62 díades de crianças com média de 13,5 meses de idade gestacional corrigida (IGC). A alimentação complementar foi introduzida no sexto mês de IGC por quase metade das mães, e a maioria delas informou algum tipo de dificuldade nessa introdução. A prematuridade extrema revelou associação com o comportamento alimentar defensivo (p=0,005), assim como a introdução inicial de alimentos na consistência liquidificada (p=0,001), o tempo prolongado de uso de sonda enteral (p=0,044), a pressão positiva em vias aéreas (CPAP) (p=0,013) e a nutrição parenteral (p=0,039). CONCLUSÃO: Não foi encontrada uma associação significativa entre a disfunção motora oral e a dificuldade alimentar.

Effect of levodopa on cochlear mechanics and efferent auditory system of Parkinson's disease individuals. / Efeito da levodopa na mecânica coclear e no sistema auditivo eferente de indivíduos com doença de Parkinson.

PURPOSE: To evaluate the effect of levodopa on cochlear dynamics and on the medial olivocochlear efferent pathway of idiopathic Parkinson's disease (PD) individuals. METHODS: Individuals with and without PD, followed at a University Hospital, were submitted to Distortion Product Otoacoustic Emissions (DPOAE) and DPOAE Inhibitory Effect (OAEIE) in the presence of contralateral noise. Correlation measures between DPOAE and OAEIE results with Hoehn&Yahr (H&Y) stage, daily dose of levodopa and PD diagnosis period were established. Furthermore, electroacoustic measures were compared between individuals without and those with PD, stratified by dose of levodopa daily administered. RESULTS: Weak negative correlation between DPOAE amplitude and daily dose of levodopa was found, as well positive correlations between EIEOA with daily dose of levodopa and time of PD diagnosis, respectively. Higher DPOAE amplitude was found in individuals with PD using daily doses of levodopa ≤ 600 milligrams when compared to individuals without PD and those with PD using higher doses. EIEOA was lower in individuals using doses ≤ 600 milligrams, when compared to the other groups. CONCLUSION: Daily doses of levodopa up to 600 mg / day increase the cochlear mechanical-transducer responses in 2 and 3 kHz frequencies, while the action of olivocochlear efferent systems is reduced in this region.

OBJETIVO: Analisar o efeito da levodopa na dinâmica coclear, bem como na via eferente olivococlear medial de indivíduos com doença de Parkinson idiopática (DP). MÉTODO: Indivíduos com e sem DP, acompanhados em um hospital universitário, realizaram a pesquisa das emissões otoacústicas por produto de distorção (EOAPD) e do efeito inibitório das EOAPD (EIEOA) na presença de ruído contralateral. Foram estabelecidas as medidas de correlação entre os resultados das EOAPD e do EIEOA com estágio Hoehn&Yahr (H&Y), dose diária de levodopa e tempo de diagnóstico da DP. Além disso, as medidas eletroacústicas foram comparadas entre os indivíduos sem DP e com DP, estratificados de acordo com a dose de levodopa administrada diariamente. RESULTADOS: Foi identificada correlação fraca e negativa entre a amplitude das EOAPD com a dose diária de levodopa e correlações positivas, de força moderada e fraca, entre o EIEOA com a dose diária de levodopa e o tempo de diagnóstico da DP, respectivamente. A amplitude das EOAPD foi maior nos indivíduos com DP em uso de levodopa ≤ 600 miligramas quando comparada à de indivíduos sem DP e com DP, em uso de dose superior. Já o EIEOA foi menor nos indivíduos em uso de doses ≤ 600 miligramas, quando comparado aos demais grupos. CONCLUSÃO: Doses diárias de levodopa iguais ou inferiores a 600 mg/dia aumentam as respostas mecanotransdutoras cocleares nas frequências de 2 e 3 kHz, enquanto que a ação dos sistemas eferentes olivococleares é reduzida nesta região.

Is silent aspiration a risk factor for respiratory infection in Parkinson's disease patients?

OBJECTIVE: To assess if silent aspiration is a risk factor for respiratory infection in patients with Parkinson's disease (PD). METHOD: From February 2006 to June 2006, 19 PD patients with diurnal sialorrhea were evaluated by swallow videofluoroscopy (VF). Two patients moved away and contact with them was lost. The other patients were divided into two groups according to the presence or absence of penetration/aspiration and were followed up for 1 year. During this period, patients were assessed for airway infections, hospital admissions, weight loss, use of nasoenteral or gastric tube and to detect cases of death. RESULTS: Silent laryngeal penetration or silent aspiration (SLP/SA) was observed in four patients. During the follow up period, three of the four patients with SLP/SA developed respiratory infection, and one of the 13 patients who did not show SLP/SA had airway infection (RR=9.75, 95% CI: 1.36-69.65). Two patients with SLP/SA developed airway infection and died, and there were two deaths in the group who had not been diagnosed for SLP/SA, one due to cardiac arrest and the other related to pancreatic cancer. CONCLUSION: The results suggest that patients with Parkinson's disease with diurnal sialorrhea and SLP/SA have an increased risk of respiratory infections, which is the main cause of death in PD patients. The data support a greater emphasis on preventive interventions for silent aspirations and silent penetration to improve survival in patients with Parkinson's disease.

Is drooling secondary to a swallowing disorder in patients with Parkinson's disease?

Drooling is a common manifestation in Parkinson's disease (PD). It causes psychosocial difficulties and can result in aspiration and chest infection. Previous studies point to an association between swallowing problems and sialorrhea. The aim of this study was to determine if drooling is associated with dysphagia in PD patients. Sixteen PD patients with diurnal drooling were assessed using a modified barium swallowing with videofluoroscopy, and a drooling score. Changes in the oral stage of swallowing were seen in 100% of the patients; and in the pharyngeal stage, in 94% of the patients. The results showed a correlation between the drooling scale score and the level of dysphagia (-0.426; p<0.05). Patients with the worst dysphagia had the worst drooling.

Silent aspiration in Parkinson's disease patients with diurnal sialorrhea.

OBJECTIVE: We studied the frequency of silent laryngeal penetration or silent aspiration (SLP/SA) in Parkinson's disease (PD) patients with diurnal sialorrhea. PATIENTS AND METHODS: In 19 consecutive PD patients with diurnal sialorrhea, swallow was evaluated using the videofluoroscopy analysis. Data were analysed to determine the frequency of aspiration and its relationship with the severity of sialorrhea. RESULTS: All patients were classified in the Hoehn and Yahr stages between 2 and 5. SLP/SA was observed in 21% of patients and the score of sialorrhea in the group with SLP/SA was 8.0+/-0.81, while in the group with no SLP/SA was 6.46+/-1.06 (p=0.02). CONCLUSION: SLP/SA is a frequent morbidity in PD patients, its risk is higher in later stages of disease and in those patients with severe sialorrhea. However, prospective and controlled studies of follow up will be necessary to determine the prognosis and management in this group of patients.

Complementary feeding in infants born prematurely.

PURPOSE: To investigate if there is difficulty in introducing complementary feeding in premature infants. METHODS: This is an exploratory, cross-sectional study performed in premature infants between six and twenty-four months of gestationally corrected age, using complementary feeding. Thirty-eight infants born prematurely were included. The feeding difficulties presented by the infants were investigated through an objective question followed by the application of a food behavior checklist for the last month. The children's clinical variables were investigated through a medical record review. An interview was conducted with those responsible for the child to identify the sociodemographic aspects and the type of breastfeeding before the corrected six months of age. RESULTS: Asked about the general perception, 50% of parents answered that their children did not present feeding difficulties in the last month. However, when a checklist was applied, 73.7% of the parents reported that their children had at least one defensive behavior at mealtime. Refusal to open their mouths (42.1%), food selectivity (28.9%), and feeding refusal (26.3%) were the most frequent defensive behaviors. The food refusal item (44.4%) had a greater association with formula feeding (p = 0.033). CONCLUSION: The present study showed an association between the type of breastfeeding and the difficulties in complementary feeding, especially in premature infants with formula feeding, presenting food refusal during meals. We found the presence of different types of defensive behaviors at mealtime in the majority of premature infants investigated.

Impact of levodopa treatment in the voice pattern of Parkinson's disease patients: a systematic review and meta-analysis.

PURPOSE: Investigate the association between levodopa therapy and vocal characteristics in Parkinson's disease patients. SEARCH STRATEGY: Studies published at MEDLINE, LILACS, and SciELO, from 1960 to December 2016. A systematic review and meta-analysis was performed using the following keywords: Parkinson's disease; levodopa; L-dopa; voice; speech disorders; dysphonia; dysarthria. After analyzing titles and abstracts, two independent reviewers selected all clinical trials that met the eligibility criteria and selected the articles and the data recorded in a previously standardized table. SELECTION CRITERIA: Trials published in English between 1960 and December 2016 individuals with clinical diagnosis of Parkinson's disease; use of levodopa therapy in stable doses; acoustic analysis combined or not with auditory-perceptual analysis to evaluate the vocal parameters under investigation. DATA ANALYSIS: The following vocal parameters were analyzed: fundamental frequency (F 0), jitter, and vocal intensity. Standardized mean differences (SMD) were calculated using the Comprehensive Meta-analysis V2 software. RESULTS: Nine articles met the eligibility criteria and were selected, with a total of 119 individuals. From these, six articles with 83 individuals were included in the meta-analysis. During the levodopa therapy "on" state, modifications in F 0 (SMD=0.39; 95% CI - 0.21-0.57) and jitter (SMD=0.23; 95% CI - 0.02-0.45) were observed. Vocal intensity was not affected (SMD=0.09; 95% CI - 0.22-0.39) by levodopa ingestion. Data of the included studies were controversial in the auditory-perceptual analysis of voice. CONCLUSION: Levodopa therapy modifies F0 and jitter. No changes in vocal intensity were observed in either the "on" or "off" states of levodopa therapy.

Does botulinum toxin decrease frequency and severity of sialorrhea in Parkinson's disease?

This study analysed if botulinum toxin type A (BTX-A) decreases drooling in 21 Parkinson's disease patients. BTX-A injections were given in the parotid glands. The severity of drooling decreased in 18 (86%) patients, while frequency was reduced in 8 (38%). In 11(52%) patients, the frequency of drooling remained constant, which may reflect more difficulties in swallowing, compared to the group that presented such improvement. Future trials assessing the level of swallowing dysfunction may be important to establish a prognosis for patients who keep the frequency of drooling in spite of decreased severity after BTX injection.

Extreme prematurity revealed an association with defensive feeding behavior (p = 0.005), as well as with the initial introduction of food with liquid consistency (p = 0.001), the extended period of time using enteral tube feeding (p = 0.044), the continuous positive airway pressure (CPAP) (p = 0.013) and parenteral nutrition (p = 0.039). Conclusion There was no significant association between oral motor disorder and feeding difficulty.

Delayed latencies of auditory evoked potential P300 are associated with the severity of Parkinson's disease in older patients.

UNLABELLED: Electrophysiological methods could provide important information about the neurophysiological status in Parkinson's disease (PD). OBJECTIVE: To investigate the prolonged auditory P300 latency in PD and its association with the disease clinical stage. METHOD: Clinical profiles of 44 patients were evaluated and those in initial and advanced stages of PD were identified. The frequency of altered latencies, median of latencies in each stage, and correlation between latencies and motor and non-motor clinical features were analyzed. Latencies were considered altered when they were more than two standard deviations from the mean of controls, per age group.
