Swallowing outcome to speech therapy intervention in resistant hypertensive patients with obstructive sleep apnea

Relationship between Quality of Life and Swallowing in Hypertensive Individuals with Obstructive Sleep Apnea

INTRODUCTION

Obstructive sleep apnea (OSA) is closely associated with resistant hypertension (RHTN). Individuals with OSA may have sensory and muscular alterations in pharyngolaryngeal structures, potentially resulting in oropharyngeal dysphagia.

OBJECTIVE

One objective of this study was to assess and compare the quality of life (QoL) and swallowing ability of resistant hypertensive patients with and without OSA. Another objective was to evaluate the relationship between QoL and changes in swallowing in patients with RHTN and OSA.

METHODS

This work was an analytical observational study with a cross-sectional design that included resistant hypertensive patients who were undergoing polysomnography (the gold standard exam for the diagnosis of OSA), fiberoptic endoscopic evaluation of swallowing (FEES), dysphagia risk assessment (Eating Assessment Tool - EAT-10) and QoL assessment in swallowing (Swal-Qol).

RESULTS

Of the 65 participants, 13 (20%) did not have OSA, 13 (20%) had mild OSA, 18 (27.7%) had moderate OSA, and 21 (32.2%) had severe OSA. Compared with those without OSA, patients with OSA had lower swallowing QoL scores ("burden", "symptoms", and "mental health"). Furthermore, pre premature leakage, onset of the pharyngeal phase in the pyriform sinus, laryngeal penetration, pharyngeal residue and oropharyngeal dysphagia were more prevalent among patients with OSA.

CONCLUSION

Resistant hypertensive patients with OSA have a greater prevalence of changes in swallowing and worse Swal-QoL scores than those without OSA, although such changes were not shown in the EAT-10. In addition, Swal-Qol is related to swallowing safety impairments among these individuals.

Effectiveness of Outpatient Treatment in Ear, Nose, and Throat Clinics for Dysphagia and the Role of Questionnaires

Background While most research on dysphagia treatment has focused on inpatients, less attention has been given to outpatient settings, particularly in ear, nose, and throat (ENT) clinics. Additionally, while questionnaires are commonly used as screening tools in dysphagia management, their correlation with outcomes such as pneumonia incidence or sustained oral intake is rarely discussed. This study aimed to evaluate the effectiveness of outpatient treatment in ENT clinics for dysphagia, including improvement in subjective symptoms, and to assess the role of the questionnaire. Methodology In total, 59 patients (38 males and 21 females) aged 53-93 years (mean age = 79 years) attended the outpatient swallowing clinic. All participants retained sufficient ability in activities of daily living to independently visit the hospital and could orally ingest food, and none required tube feeding. Subjective symptoms were evaluated using the questionnaire. Swallowing assessments were conducted by an otolaryngologist and via swallowing endoscopy. A speech-language pathologist led the swallowing rehabilitation, which included encouraging family involvement and home practice. Results The most frequent issue reported was munching during meals. Of the 59 patients, 22 underwent continuous outpatient rehabilitation. Of these, 17 (77%) showed improvement; 11 had improvement in both subjective symptoms and fiberoptic endoscopic evaluation of swallowing (FEES) scores, five in subjective symptoms only, and one in FEES scores only. Five patients showed no change/worsening conditions. Conclusions The questionnaire proved useful as a screening tool but fell short in terms of prognosis estimation. The findings suggest that information from the questionnaire should be used to gauge treatment effectiveness, noting that some cases showed improvement in subjective symptoms alone.

Outpatient Treatment of Mild Dysphagia in Ear-Nose-and-Throat Clinics

OBJECTIVE

Many reports on inpatient dysphagia rehabilitation in acute and convalescent rehabilitation hospitals exist, but there are a few reports on outpatient treatments. Otolaryngologists still take a trial-and-error approach when treating dysphagia. Here, we explore the effectiveness and limitations of outpatient treatment in ear-nose-and-throat (ENT) clinics.

METHODS

Sixty-four patients (41 males and 23 females) aged 27-101 years (mean 78 years) visited an outpatient clinic specialising in feeding and swallowing conditions (the Fukuyo ENT Clinic). All were able to perform the activities of daily living (ADL) to the extent that outpatient visits were possible; no home visits were made. The weekly outpatient day was staffed by an otolaryngologist and a speech-language-hearing therapist (SLHT). All patients were subjected to fibreoptic endoscopic evaluation of swallowing (FEES), followed by appropriate training as revealed by the examinations.

RESULTS

Salivary retention in the glottis valley and piriform sinuses improved (both p < 0.05) in 30 patients who underwent repeat FEES; we compared the initial and final figures. In 14 cases in whom maximal tongue pressure (TP) was measured, this was higher at the final than at the first examination (p < 0.01).

CONCLUSION

Outpatient treatment at ENT clinics for patients who are able to maintain their ADLs to the extent that they are able to walk to a hospital is an option for the treatment of age-related dysphagia. For severe cases, however, house calls and collaboration with the home and nursing care sector will be necessary and should be considered in the future.
