As the author stated in the conclusion, presbyphagia should be considered an etiology of oropharyngeal dysphagia (OD). However, significant methodological flaws were found, including selecting only one person to screen and analyze articles in the systematic review, not using any keywords or MeSH terms in the search, not presenting a search strategy, limiting the search term to \"presbyphagia\", and omitting details about screening, inclusion, and exclusion criteria. The operational definitions describe that aging inherently causes swallowing impairment. However, they disregard age-related changes without significant functional impact, as found by a previous study, reviewed in the current research, but analyzed inconsistently by the author. This recent study showed that presbyphagia is the opposite of OD, framing both the \"negative\" aspects of swallowing and the \"compensatory positives\" as natural consequences of aging, consistent with the World Health Organization's concept of intrinsic capacity. This perspective positions aging as an adaptive process-not a disease or cause of disease-, although it may increase vulnerability due to cumulative factors. Since OD is a symptom, attributing it to aging frames aging itself as a disease, contradicting current geriatrics and gerontology paradigms.</p>","PeriodicalId":11508,"journal":{"name":"Dysphagia","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143763428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Retention, training, and HEP accuracy were tracked at biweekly visits and during HEP for participants with access to a biofeedback device. Associations with tongue strength outcomes, participant factors, biofeedback, and intensity dosing were analyzed. Exercise accuracy measures did not contribute to tongue strength outcomes at the end of 8 weeks. Increased training accuracy (less practice required to achieve competency) was associated with higher participant confidence and better adherence to the HEP. The presence of biofeedback was associated with reduced adherence but better retention accuracy, while maximal intensity was associated with improvements in all accuracy measures compared to submaximal intensity exercise. These findings in typically aging participants suggest the need for tailored approaches in swallowing-related exercise programs, given the effects of biofeedback and exercise intensity on motor learning and exercise retention.

Neither the PAS nor the Pooling score differed significantly between the three different boluses. Aspiration was never observed during swallowing any bolus with particles.

Despite valuable information obtained from these boluses, it remains common practice to use a single bolus (e.g., the worst score) to describe the degree of dysfunction. Researchers also often collapse continuous or ordinal swallowing measures into categories, potentially exacerbating information loss. These practices may adversely affect statistical power to detect and estimate smaller, yet potentially meaningful, treatment effects. This study sought to examine the impact of aggregating and categorizing penetration-aspiration scale (PAS) scores on statistical power and effect size estimates. We used a Monte Carlo approach to simulate three hypothetical within-subject treatment studies in Parkinson's disease and head and neck cancer across a range of data characteristics (e.g., sample size, number of bolus trials, variability). Different statistical models (aggregated or multilevel) as well as various PAS reduction approaches (i.e., types of categorizations) were performed to examine their impact on power and the accuracy of effect size estimates. Across all scenarios, multilevel models demonstrated higher statistical power to detect group-level longitudinal change and more accurate estimates compared to aggregated (worst score) models. Categorizing PAS scores also reduced power and biased effect size estimates compared to an ordinal approach, though this depended on the type of categorization and baseline PAS distribution. Multilevel models should be considered as a more robust approach for the statistical analysis of multiple boluses administered in standardized swallowing protocols due to its high sensitivity and accuracy to compare group-level changes in swallowing function. Importantly, this finding appears to be consistent across patient populations with distinct pathophysiology (i.e., PD and HNC) and patterns of airway invasion. The decision to categorize a continuous or ordinal outcome should be grounded in the clinical or research question with recognition that scale reduction may negatively affect the quality of statistical inferences in certain scenarios.</p>","PeriodicalId":11508,"journal":{"name":"Dysphagia","volume":" ","pages":"388-398"},"PeriodicalIF":2.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141995496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-two SLPs from 5 sites participated in a blinded longitudinal DIGEST rating study. Raters were provided a standardized training set of MBS (n = 19).

Seventy-five percent of raters (24/32) demonstrated reliability ≥ 0.61 in the substantial to almost perfect range prior to training.
