The Occurrence Rate of Swallowing Disorders After Stroke Patients in Asia: A PRISMA-Compliant Systematic Review and Meta-Analysis.

BACKGROUND: Swallowing disorders (dysphagia) is common in stroke patients. However, the epidemiology of post-stroke dysphagia (PSD) is poorly described. We herein synthesize the data of eligible studies on occurrence rate of dysphagia in Asian populations with stroke. METHODS: We searched the electronic databases (PubMed, Embase and Web of Science) to collect the studies on the prevalence of PSD. We used the Newcastle-Ottawa Scale (NOS) to estimate the quality of studies. The pooled dysphagia occurrence rate was obtained in Asian stroke patients. RESULTS: 40 studies (including 43 observations) from 2318 initial references were selected in the synthetic analysis. The pooled occurrence rate of dysphagia in post-stroke patients was 36.3% (95% CI, 33.3%-39.3%). Meta-regression analysis showed that the "country" and "developing level" may influence the pooled occurrence rate of PSD. CONCLUSION: Dysphagia is common in Asian post-stroke patients. Our meta-analysis may raise concern about evaluating and managing dysphagia in stroke patients.

The Relationship Between Culture, Quality of Life, and Stigma in Hispanic New Mexicans With Dysphagia: A Preliminary Investigation Using Quantitative and Qualitative Analysis.

Purpose The purpose of this investigation was to (a) identify the relationship between level of acculturation, and quality of life (QOL) and stigma and (b) explore the QOL experiences for Hispanic New Mexicans with dysphagia. Method This study includes 7 New Mexicans who self-identified as Hispanic. This prospective investigation was completed in 2 phases. In the quantitative phase, all participants completed the (a) the SWAL-QOL ( McHorney et al., 2000 ), (b) the Neuro-QoL Stigma subtest ( Gershon et al., 2012 ), and (c) the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II; Cuellar, Arnold, & Maldonado, 1995 ). In the qualitative phase, 3 participants were selected from the quantitative phase to complete the qualitative phase. These participants were selected to allow for distribution across levels of acculturation, and each of them participated in interviews designed to explore QOL experiences. Interviews were analyzed to identify themes. The occurrence of themes is discussed as a function of level of acculturation. Results There is no clear relationship between acculturation and QOL. A strong nonsignificant correlation was observed between acculturation and stigma. QOL experiences, as identified from the interviews, were classified into 2 broad categories: emotional experiences (stigma, distrust, fear, frustration, religion, and impact) and swallow safety (symptoms, treatment, triggers, and compensatory strategies). Conclusions Level of acculturation did not relate to measures of mental health or fatigue. Yet, both quantitative and qualitative analyses support a relationship between level of acculturation, and symptom reporting and religion, as well as patient perception of stigma.

Systematic review: Eosinophilic esophagitis in Asian countries.

AIM: To investigate the prevalence and the clinical characteristics of Asian patients with eosinophilic esophagitis. METHODS: We conducted a systematic search of the PubMed and Web of Science databases for original studies, case series, and individual case reports of eosinophilic esophagitis in Asian countries published from January 1980 to January 2015. We found 66 and 80 articles in the PubMed and Web of Science databases, respectively; 24 duplicate articles were removed. After excluding animal studies, articles not written in English, and meeting abstracts, 25 articles containing 217 patients were selected for analysis. RESULTS: Sample size-weighted mean values were determined for all pooled prevalence data and clinical characteristics. The mean age of the adult patients with eosinophilic esophagitis was approximately 50 years, and 73% of these patients were male. They frequently presented with allergic diseases including bronchial asthma, allergic rhinitis, food allergy, and atopic dermatitis. Bronchial asthma was the most frequent comorbid allergic disease, occurring in 24% of patients with eosinophilic esophagitis. Dysphagia was the primary symptom reported; 44% of the patients complained of dysphagia. Although laboratory blood tests are not adequately sensitive for an accurate diagnosis of eosinophilic esophagitis, endoscopic examinations revealed abnormal findings typical of this disease, including longitudinal furrows and concentric rings, in 82% of the cases. One-third of the cases responded to proton pump inhibitor administration. CONCLUSION: The characteristics of eosinophilic esophagitis in Asian patients were similar to those reported in Western patients, indicating that this disease displays a similar pathogenesis between Western and Asian patients.

Validation and Cultural Adaptation of the Arabic Version of the Eating Assessment Tool (EAT-10).

BACKGROUND AND OBJECTIVES: The Eating Assessment Tool (EAT-10) is a 10-item self-administered questionnaire. It is a noninvasive tool to measure patients' perception of their swallowing problems. The purposes of the present study were to develop an Arabic version of the EAT-10 and to evaluate its validity, consistency, and reliability in the Arabic-speaking population with oropharyngeal dysphagia. SETTING AND DESIGN: This was a prospective study carried out at the Communication and Swallowing Disorders Unit, King Saud University, Riyadh, Saudi Arabia. SUBJECTS AND METHODS: The Arabic EAT-10 was administered to 138 patients with oropharyngeal dysphagia and 83 control subjects. Internal consistency and test-retest reliability were evaluated. Content and clinical validity were studied, and the EAT-10 results were compared across patients and control groups. RESULTS: The Arabic EAT-10 showed excellent internal consistency (Cronbach's α = 0.92). Also, good test-retest reliability was found for the total scores of the Arabic EAT-10 (intraclass correlation = 0.73). There was a significant difference in Arabic EAT-10 scores between the oropharyngeal dysphagia group and the control group (p < 0.001). CONCLUSION: This study demonstrated that the Arabic EAT-10 is a valid tool that can be used for screening of dysphagia-related problems in an Arabic-speaking population.

Pharyngeal transit adaptation to bolus volume and consistency in Chagas' disease / Adaptação do trânsito faríngeo ao volume e consistência do bolo deglutido na doença de Chagas

Background: Esophageal Chagas' disease causes a longer pharyngeal bolus clearance, which may be an adaptation to the impairment of esophageal bolus transit. This adaptation should be present when we change volume or consistency of the swallowed bolus. Methods: By the videofluoroscopic method, the correlation was calculated between bolus volumes of 5 and 10mL, and consistencies liquid and paste on pharyngeal clearance duration and hyoid movement duration using the Pearson correlation coefficient (r). It was evaluated 17 patients with Chagas' disease and 15 normal volunteers. Results: In both groups, there was no correlation between the pharyngeal clearance duration and the hyoid movement duration. In pharyngeal clearance there was a positive correlation between the volumes of 5 and 10mL and between liquid and paste boluses in patients with Chagas' disease, but not in controls. In hyoid movement duration the correlation between the volumes of 5 and 10mL was positive and significant in Chagas' disease patients for liquid and paste bolus, and only for paste in controls. Conclusion: Patients with Chagas' disease have a positive correlation of bolus flow through the pharynx related to change in bolus volume and bolus consistency, which suggested that they have a more important control of pharyngeal flow related to bolus volume and consistency than normal volunteers...

Justificativa: Envolvimento do esôfago pela doença de Chagas provoca aumento na duração da depuração da faringe, o que pode ser uma adaptação consequente ao comprometimento do trânsito do bolo pelo esôfago. Esta adaptação deve estar presente quando variamos o volume e consistência do bolo deglutido. Métodos: Foi realizada, com o método videofluoroscópico, avaliação da duração da depuração faríngea e da duração do movimento do osso hióide com a deglutição de bolos de 5 e 10mL, e consistências líquida e pastosa em 17 pacientes com doença de Chagas e 15 voluntários saudáveis. Foi calculada a correla­ção entre os resultados por meio do coeficiente de correlação de Pearson (r). Resultados: Em pacientes com doença de Chagas e voluntários, não houve correlação entre a duração da depuração da faringe e da duração do movimento do hióide. Em pacientes com doença de Chagas, na depuração da faringe, houve correlação positiva entre os volumes de 5 e 10mL e entre bolos líquido e pastoso, o que não foi observado nos voluntários. Na duração do movimento do hióide a correlação entre os volumes de 5 e 10mL foi positiva e significativa em pacientes com doença de Chagas para bolo líquido e pastoso, e apenas para pastoso nos voluntários. Conclusão: Pacientes com doença de Chagas têm correlação positiva do fluxo pela faringe relacionada com a alteração no volume e consistência do bolo, o que sugere um maior controle do fluxo pela faringe do que o observado em voluntários normais...

Maximizing health literacy and client recall in a developing context: speech-language therapist and client perspectives.

BACKGROUND: In the field of speech-language therapy, limited research has been conducted with regards to health literacy and client recall. However, speech-language therapists frequently provide a considerable amount of information for clients to understand, apply and review in order to manage their (or their child's) health. AIMS: This study aimed to investigate (1) issues around clients' health literacy and recall of information; and (2) how these issues can be overcome in speech-language therapy in a developing context. METHOD & PROCEDURES: An exploratory study was undertaken with specific focus on speech-language therapists and their clients who had previously received treatment for dysphagia, voice disorders (including laryngectomies), and cleft lip and/or palate management. They were recruited at public tertiary hospitals and primary healthcare clinics in Cape Town, South Africa. Data were gathered through focus group discussions and qualitatively analysed using a content-driven immersion/crystallization style. OUTCOMES & RESULTS: Five themes and 13 subthemes were identified. Speech-language therapists currently use mostly low-technology strategies to manage issues of health literacy and client recall, and frequently view poor outcomes as being related to clients themselves and a lack of compliance. CONCLUSIONS & IMPLICATIONS: An understanding of context, intercultural health literacy and client-provider concordance are important factors that should inform the clinical practice of speech-language therapy. There is a need to develop effective strategies for information provision and review post-consultation. Speech-language therapists have an important mediating role in cross-cultural communication.

Racial disparities in the development of dysphagia after stroke: further evidence from the Medicare database.

OBJECTIVE: To describe the relationship between minority race/ethnicity and dysphagia after stroke in a national sample. Unlike the multiple studies that have examined racial disparities in stroke incidence, risk factors, outcomes, and quality of care, the influence of race or ethnicity on dysphagia after stroke has been understudied. We hypothesized that the odds of dysphagia would be higher for Asians compared with Caucasians in the United States given the results of a previous study in the U.S. DESIGN: Observational study. SETTING: Conducted using the U.S. National Medicare Medical Provider Analysis and Review Data. PARTICIPANTS: Medicare beneficiaries admitted in 2007 with a stroke diagnosis. INTERVENTION: We selected 382,959 cases with cerebrovascular disease codes with self-identified race/ethnicity of Caucasian, African American, Asian, Hispanic, Native American, or other/unknown. Cases had a diagnosis of cerebrovascular disease, defined as International Classification of Disease, Ninth Revision codes 430 to 438.9. Self-reported race/ethnicity was recorded in the following categories: Caucasian, African American, Asian, Hispanic, Native American, and other/unknown. MAIN OUTCOME MEASURE: Dysphagia after stroke as coded in the data. RESULTS: The adjusted odds ratio (OR) for poststroke dysphagia was higher for Asians and other minority groups compared with Caucasians (Asian: OR, 1.73; 95% confidence interval [CI], 1.60-1.88; Hispanic: OR, 1.50; 95% CI, 1.39-1.63; African American: OR, 1.42; 95% CI, 1.37-1.47; unknown/other: OR, 1.27; 95% CI, 1.16-1.38; Native American; OR, 1.44; 95% CI, 1.22-1.69). CONCLUSIONS: Our findings confirm previous research suggesting an association between Asian race and dysphagia after stroke while adding evidence for increased odds in other racial/ethnic minority groups.

Racial disparities in the development of dysphagia after stroke: analysis of the California (MIRCal) and New York (SPARCS) inpatient databases.

OBJECTIVES: To determine whether the proportion of patients with stroke experiencing dysphagia differs among racial groups and whether this relation can be explained by stroke type or severity. DESIGN: Case-control study using California's Medical Information Reporting and New York's Statewide Planning and Research Cooperative System databases for 2002. Cases had primary diagnosis of cerebrovascular disease (International Classification of Disease, 9th Revision [ICD-9] codes 430-438.9, excluding transient [435-435.9] and late-effects [438-438.9]), and self-identified race was white, black, or Asian. Two comparison groups were selected: (1) Parkinson's disease (ICD-9 codes 332-332.1) and (2) oral cancer (ICD-9 codes 141-149). SETTING: Inpatient admissions in the respective states. PARTICIPANTS: Cases with primary diagnosis of cerebrovascular disease whose self-identified race was white, black, or Asian. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Dysphagia, defined by ICD-9 codes 787.2 (dysphagia), 507.0 (aspiration pneumonia), or presence of a feeding tube in the absence of a diagnosis of coma (Current Procedural Terminology codes 432.46 or 437.50 without ICD-9 code 780.01). RESULTS: In the stroke group, the adjusted odds ratio (OR) with 95% confidence interval (CI) for dysphagia was significantly higher for Asians than whites in New York (OR=1.64; 95% CI, 1.50-1.79) and California (OR=1.69; 95% CI, 1.34-2.13). The adjusted OR was slightly but significantly higher for blacks than whites in New York (OR=1.15; 95% CI, 1.03-1.28), but not in California (OR=1.08; 95% CI, 0.97-1.19). No statistically significant differences among racial groups were found in patients with Parkinson's disease or oral cancer. Other factors strongly associated with dysphagia included hemiplegia (OR=2.19; 95% CI, 2.07-2.32) and aphasia (OR=1.97; 95% CI, 1.83-2.11). CONCLUSIONS: Asians were more likely to have dysphagia after stroke. This association was statistically significant after adjusting for age, sex, stroke severity indicators, comorbidities, and stroke type.
