Predictive Value of Cough Frequency in Addition to Aspiration Risk for Increased Risk of Pneumonia in Dysphagic Stroke Survivors: A Clinical Pilot Study

Background: Post-stroke dysphagia leads to increased risk of aspiration and subsequent higher risk of pneumonia. It is important to not only diagnose post-stroke dysphagia early but also to evaluate the protective mechanism that counteracts aspiration, i.e., primarily cough. The aim of this study was to investigate the predictive value of cough frequency in addition to aspiration risk for pneumonia outcome. Methods: This was a single-center prospective observational study. Patients with first-ever strokes underwent clinical swallowing evaluation, fibreoptic endoscopic evaluation of swallowing (FEES), and overnight cough recording using LEOSound® (Löwenstein Medical GmbH & Co. KG, Bad Ems, Germany ). Penetration–Aspiration Scale (PAS) ratings and cough frequency measurements were correlated with incidence of pneumonia at discharge. Results: 11 women (37%) and 19 men (63%), mean age 70.3 years (SD ± 10.6), with ischemic stroke and dysphagia were enrolled. Correlation analysis showed statistically significant relationships between pneumonia and PAS (r = 0.521; p < 0.05), hourly cough frequency (r = 0,441; p < 0.05), and categories of cough severity (r = 0.428 p < 0.05), respectively. Logistic regression showed significant predictive effects of PAS (b = 0.687; p = 0.014) and cough frequency (b = 0.239; p = 0.041) for pneumonia outcome. Conclusion: Cough frequency in addition to aspiration risk was an independent predictor of pneumonia in dysphagic stroke survivors.

Reassessment of Poststroke Dysphagia in Rehabilitation Facility Results in Reduction in Diet Restrictions

Background: Dysphagia assessment in postacute stroke patients can decrease the incidence of complications like malnutrition, dehydration, and aspiration pneumonia. It also helps to avoid unnecessary diet restrictions. The aim of this study is to verify if regular reassessment of dysphagia would change the diet management of postacute stroke patients in rehabilitation settings. Methods: This single-center retrospective study included 63 patients referred to an inpatient neurological rehabilitation center between 2018–2019. A standardized clinical swallowing evaluation and Fiberoptic Endoscopic Evaluation of Swallowing (FEES) were performed. Diet level according to Functional Oral Intake Scale (FOIS) was evaluated. As the primary endpoint, the FOIS values based on diagnostic procedures were assessed at hospital discharge, rehabilitation admission, and after FEES. Results: 19 women (30%) and 44 men (70%), with a mean age of 75 y (SD ± 10.08), were enrolled. The intergroup ANOVA revealed significant differences (p < 0.001) between dietary prescriptions in an acute care setting and following clinical and endoscopic reassessment in the rehabilitation center. Diet recommendations changed in 41 of 63 (65%) enrolled patients (p < 0.001). Conclusion: Instrumental diagnostic by FEES during the early convalescence period of stroke patients leads to clinically relevant changes to diet restrictions and lower rates of pneumonia. Our findings underline the need for regular and qualitative dysphagia diagnostics in stroke patients participating in neurological rehabilitation.

White Paper by the European Society for Swallowing Disorders: Screening and Non-instrumental Assessment for Dysphagia in Adults

This White Paper by the European Society for Swallowing Disorders (ESSD) reports on the current state of screening and non-instrumental assessment for dysphagia in adults. An overview is provided on the measures that are available, and how to select screening tools and assessments. Emphasis is placed on different types of screening, patient-reported measures, assessment of anatomy and physiology of the swallowing act, and clinical swallowing evaluation. Many screening and non-instrumental assessments are available for evaluating dysphagia in adults; however, their use may not be warranted due to poor diagnostic performance or lacking robust psychometric properties. This white paper provides recommendations on how to select best evidence-based screening tools and non-instrumental assessments for use in clinical practice targeting different constructs, target populations and respondents, based on criteria for diagnostic performance, psychometric properties (reliability, validity, and responsiveness), and feasibility. In addition, gaps in research that need to be addressed in future studies are discussed. The following recommendations are made: (1) discontinue the use of non-validated dysphagia screening tools and assessments; (2) implement screening using tools that have optimal diagnostic performance in selected populations that are at risk of dysphagia, such as stroke patients, frail older persons, patients with progressive neurological diseases, persons with cerebral palsy, and patients with head and neck cancer; (3) implement measures that demonstrate robust psychometric properties; and (4) provide quality training in dysphagia screening and assessment to all clinicians involved in the care and management of persons with dysphagia.

The relation between aspiration and oropharyngeal components of swallowing in Amyotrophic Lateral Sclerosis (ALS)

The aim of this study is to examine the relation between aspiration and oral and pharyngeal components of swallowing in patients with ALS. 19 participants diagnosed with ALS followed in outpatient clinic at HC-Unicamp, the patients were underwent to a clinical swallowing evaluation (indirect and direct) and modified barium swallowing evaluation. Results: 63.2% of the participants showed aspiration. Oral escape in the interlabial region with no progression to the anterior lip, slow/weak movement during bolus transport and decreased the wave of the pharyngeal contraction were observed. And also, the results showed positive and moderate correlation between the presence of aspiration and pharyngeal wave pharyngeal function instead of oral phase.

A Prospective Biopsychosocial Investigation Into Head and Neck Cancer Caregiving

Purpose: Head and neck cancer (HNC) patients suffer from significant morbidity, which may introduce challenging care demands and subsequent stress-induced mind–body interactions for informal caregivers. This prospective study evaluated patient and caregiver predictors of diurnal cortisol rhythm among HNC caregivers during radiation treatment. Method: Patient–caregiver dyads completed measures at radiation treatment start (T1; n = 32) and 5 weeks into treatment (T2; n = 29). Measures included the Functional Assessment of Cancer Therapy–Head and Neck, the Caregiver Quality of Life (QOL) Index–Cancer, the Caregiver Reaction Assessment, the Medical Outcomes Social Support Survey, and the Eating Assessment tool. Patients also received a clinical swallowing evaluation using the Functional Assessment of Oral Intake Scale. Caregiver cortisol concentrations were assessed from salivary samples at T1 and T2. Results: Caregiver cortisol slope became significantly flatter during radiation treatment. Greater caregiver schedule burden was associated with a flatter cortisol slope (β = .35, p = .05) in caregivers at T1. Lower patient functional QOL (β = −.41, p = .05) and lower overall caregiver QOL at T1 (β = −.39, p = .04) were each separately associated with a flatter cortisol slope in caregivers over treatment. Conclusions: Results suggest the presence of a mind–body interaction in HNC caregivers. Dysregulation in diurnal cortisol rhythm in caregivers was significantly associated with increased caregiver schedule burden and lower patient and caregiver QOL. Targeted interventions developed for HNC caregivers may help to prevent negative health outcomes associated with dysregulated cortisol.

Comparing Simultaneous Clinical Swallow Evaluations and Fiberoptic Endoscopic Evaluations of Swallowing: Findings and Consequences

Introduction: Simultaneous blinded comparisons between the results of a clinical swallowing evaluation (CSE) and fiberoptic endoscopic evaluation of swallowing (FEES) were performed. Methods: Raters were two groups of speech-language pathologists (SLPs) with expertise in dysphagia. One group analyzed the FEES video alone and the other group analyzed the CSE video alone. No consistent agreement was found between the CSE and FEES raters regarding pharyngeal and laryngeal anatomy and physiology, bolus flow characteristics, and oral diet recommendations. Results: There was also no consensus on the need for instrumental testing. Watching the CSE video alone prevented expert SLPs who use a CSE from determining pharyngeal and laryngeal anatomy and physiology, bolus flow characteristics, silent aspiration, and making informed diet recommendations and intervention strategies. Watching the FEES video alone allowed expert SLPs who use FEES to determine pharyngeal and laryngeal anatomy and physiology and bolus flow characteristics and make evidence-based oral diet recommendations. Discussion: A CSE does not have good clinical utility for determining pharyngeal dysphagia. The consequences of these results will be discussed.
