Dysphagia最新文献

Dysphagia affects up to 70% of older adults living in residential long-term care settings (RLTCS) and may lead to serious complications if not identified and adequately managed. However, there is a dearth of clinical guidelines tailored to older adults at risk of dysphagia in RLTCS. An online survey consisting of 40 questions was conducted to identify dysphagia screening practices, referral patterns and interventions implemented by nurses in cases of suspected dysphagia, to quantify the number of residents with dysphagia, episodes of aspiration pneumonia in the previous year, and use of modified texture diets and fluids and explore differences between groups of RLTCS. The survey was developed using Qualtrics XM Platform and circulated via email, with one response per RLTCS sought. Data were analysed using RStudio. Of the 429 RLTCS contacted, 45 completed and returned the survey, a 10.5% response rate. Dysphagia screening practices, referral patterns, and dysphagia management interventions varied across participating RLTCS. All participants reported that they observe for signs and symptoms of dysphagia at mealtimes to identify residents at-risk of dysphagia. Ninety six percent of RLTCS reported referring residents with suspected dysphagia to speech and language therapy dysphagia services. A diagnosis of dysphagia was reported in 35.3% of residents. All participating RLTCS reported providing modified texture diets and fluids if residents had suspected dysphagia. The implementation of standardised and validated dysphagia screening protocols in RLTCS in the Republic of Ireland may be useful in supporting the identification of at-risk residents.

Clinicians should consider disorders of masticatory muscle including lateral pterygoid muscle as a differential diagnosis in patients presenting with dysphagia and trismus after tooth extraction.

Swallowing is an essential process to maintain homeostasis in the human body. With aging, changes occur in both central and peripheral structures, giving rise to presbyphagia, involving morphological and functional alterations in swallowing. However, there is a lack of consensus on the definition of presbyphagia and its relationship with dysphagia. The primary objective of this research is to analyze the proposed definitions for the term "presbyphagia" in specialized literature and, secondarily, to assess how these definitions can influence the diagnosis of oropharyngeal dysphagia (OD). A systematic review was conducted to analyze the proposed definitions of presbyphagia and their impact on dysphagia diagnosis. Three main approaches to the definitions of presbyphagia were identified: (1) presbyphagia as an alteration in the swallowing process in healthy older adults, (2) presbyphagia as a swallowing disorder compensated by the physiological potential of healthy older adults, and (3) presbyphagia as a synonym for dysphagia. This study addresses the need for a clear definition of presbyphagia in older adults. It is concluded that presbyphagia should be understood as the etiology of OD rather than a compensated disorder or a synonym. This has significant implications for the diagnosis and treatment of swallowing disorders in the aging population. Given the ongoing nature of scientific discussion in this field, further research is required.

Insufficient suprahyoid muscle strength with poor opening of the upper esophageal sphincter can cause dysphagia. This study investigated whether an exercise of the suprahyoid muscle, named forehead exercise for suprahyoid muscles (FESM, "Enge-Odeko-Taiso" in Japanese), improves the geniohyoid muscle area and intensity using ultrasonography. Sixty-four participants (15 men and 49 women, 82.8 ± 6.0 years) living independently with no symptoms of swallowing difficulties were enrolled. The participants were divided into the FESM and the control group. The FESM is an isometric exercise involving repetitions of looking into the navel as if the chin is pulled back with little neck motion using a hand pushed against the forehead for resistance. This exercise is performed five times in 10 courses a day (total 50 times) for 8 weeks. Participants in the control group did not conduct any exercises. Body mass index, hand grip strength, gait speed, calf circumference, Mini Nutritional Assessment short-form, eating assessment tool, repetitive saliva swallowing test (RSST), and Food Intake LEVEL Scale scores were examined. The ultrasonographic geniohyoid muscle area, intensity, and RSST were investigated before and after the program. In the FESM group, the geniohyoid muscle area increased from 2.24 to 2.52 cm² (P < 0.05), intensity decreased from 34.6 to 32.0 (P < 0.05), and the median RSST increased from 5 to 6 (P < 0.05) significantly. Conversely, no significant differences were observed in the control group. The FESM was effective to increase the area and decrease the intensity of the geniohyoid muscle and may improve swallowing function.

Trismus commonly arises after surgery for head and neck cancer (HNC) and its severity is potentiated by postoperative radiotherapy. While the benefit of trismus rehabilitation after surgery and radiotherapy is well established, the evidence during radiotherapy is less clear. This may be due to poor adherence to trismus exercises secondary to acute mucositis. This study assessed the feasibility of using a novel trismus device during adjuvant radiotherapy for HNC in patients with acute postoperative trismus. Prospective single-arm cohort feasibility study. Eligible patients had undergone surgery with curative intent for HNC, planned for adjuvant radiotherapy, and were suitable for trismus rehabilitation. Participants completed a 10-week exercise program using a novel jaw stretching device. Study outcomes were adherence, maximal incisal opening (MIO), and trismus-related function and quality of life scores, assessed at baseline, 10 weeks, and 6 months after commencing exercises. Nine patients diagnosed with trismus after primary surgery were recruited. The mean increase in MIO at 10 weeks was 7.8 mm (range -4 to 15 mm, p = 0.03), and at 6 months was 10.6 mm (range 1-26 mm, p = 0.03). Significant improvements were observed in trismus-related quality of life (Gothenburg Trismus Questionnaire; p = 0.04). Adherence to the exercises was 100% in week 1-2, 67% in weeks 3-6, and 100% at 10 weeks (1 month post radiation). This study demonstrates the feasibility of using a novel jaw stretching device during adjuvant radiotherapy. Further evaluation is warranted to assess the effectiveness of early intervention and prevention of trismus during HNC radiotherapy.Level of Evidence: IV.

There is little evidence regarding the long-term prognosis of patients with aspiration pneumonia. This study aimed to investigate post-discharge survival time and prognostic factors in older patients hospitalized for aspiration pneumonia. This retrospective cohort study included patients aged ≥ 65 years hospitalized for aspiration pneumonia and discharged alive from a tertiary care hospital in Japan between April 2009 and September 2014. Candidate prognostic factors were patient's age, sex, body mass index (BMI), performance status, chronic conditions, CURB-65 score, serum albumin level, hematocrit concentration, nutritional pathway at discharge, and discharge location. Kaplan-Meier curves were determined and multivariable survival analysis using Cox regression model was performed to analyze the effect of each factor on mortality. In total, 209 patients were included in this study. The median age was 85 years, 58% of the patients were males, 33% had a performance status of 4 and 34% were discharged home. Among the patients, 65% received oral intake, 23% received tube feeding, and 21% received parenteral nutrition at discharge. During the follow-up period, 77% of the patients died, and the median post-discharge survival time was 369 days. Besides male sex and low BMI, tube feeding (adjusted hazard ratio (aHR) = 1.70, 95% confidence interval (CI) 1.11-2.59) and parenteral nutrition (aHR = 4.42, 95% CI 2.57-7.60) were strongly associated with mortality. Long-term prognosis of patients hospitalized for aspiration pneumonia was extremely poor. The nutritional pathway at discharge was a major prognostic factor. These results may be useful for future care and research.

Airway invasion is common in patients with Parkinson's disease (PD) and can cause serious complications. However, a PD-related dysphagic pattern has not been clearly elucidated. In this study, 53 patients with early to moderate PD were enrolled to undergo a videofluoroscopic study of swallowing evaluation (VFSS) and a battery of neuropsychological assessments. A set of VFSS variables (three visuoperceptual, nine temporal, and six spatial) were measured. The main effects of bolus viscosity and volume on airway invasion were calculated. Statistical analyses were performed to determine key kinematic factors of airway invasion for swallowing each bolus type. Airway invasion frequency was significantly higher for liquid boluses (liquid vs. pudding P < 0.001; liquid vs. honey P = 0.006). Laryngeal vestibule closure reaction time (LVCrt) was the key kinematic factor of airway invasion for 3 ml liquid swallow (P = 0.040), anterior displacement of hyoid bone was the key kinematic factor for both 5 ml and 10 ml liquid swallows (P = 0.010, 0.034, respectively). Male sex and advanced Hoehn and Yahr stage were significantly related to reduced anterior displacement of hyoid bone. These results reveal the dysphagic pattern related to PD, demonstrating that prolonged LVCrt and reduced anterior displacement of hyoid bone are two crucial kinematic factors contributing to airway invasion during the liquid swallow. In addition, hyoid bone dysfunction was correlated with disease severity and male sex. Our findings warrant further investigation of the pathophysiological mechanism of dysphagia in PD and would guide clinical intervention.

The aim of this study was to investigate the measures of displacement, time and velocity of hyoid bone movement in female thyroidectomy patients. Fifty-eight ultrasound videos of 29 women during swallowing were analyzed. The sample was divided into experimental group (EG), composed of 12 women following total or partial thyroidectomy; and control group (CG) of 17 healthy women. The kinematic measures of displacement, time and velocity of hyoid bone displacement were tracked during swallowing of 10 ml of liquid (water) and 10 ml of thickened liquid (honey) in both groups for comparisons. Additional analysis included bolus consistency effect and relationship with clinical characteristics. Ultrasound videos were analyzed according to a standardized protocol using ImageJ software. Displacement, time and velocity of hyoid movement during swallowing of 10 ml of liquid or thickened liquid were not statistically different between female thyroidectomy patients and healthy women. There is no bolus consistency effect on kinematic measures in both groups, but among thyroidectomy patients, velocity of hyoid bone movement is significantly faster in those with swallowing complaints.

Adequate tongue and lip strengths are needed for normal speech, chewing, and swallowing development. The aim was to evaluate the influence of sex and age on maximum anterior tongue strength (MTS) and maximum lip strength (MLS) in healthy Spanish adults to establish reference values that can be used in clinical practice.This cross-sectional study comprises 363 subjects (mean age 47.5 ± 20.7 years) distributed by sex (258 women and 105 men) and across three age groups: Young (18-39 years), middle-aged (40-59 years), and older adults (> 59 years). MTS and MLS were determined using the Iowa Oral Performance Instrument (IOPI). The mean MTS was 49.63 ± 13.81 kPa, regardless of sex, and decreased with age. The mean MLS was statistically higher for men (28.86 ± 10.88 kPa) than for women (23.37 ± 6.92 kPa, p = 0.001), regardless of age.This study provides the first reference values for the standardized measurement of MTS and MLS in a healthy adult Spanish-speaking population using the IOPI.
