Abstract
The ideal texture of pureed diets to prevent aspiration pneumonia remains unclear. The aim of this study was to evaluate the effectiveness of a pureed diet with either a gelling agent or a xanthan gum-based thickener to prevent pharyngeal residues in patients with dysphagia. We retrospectively analyzed a randomized, crossover trial of pureed rice with either a gelling agent or a xanthan gum-based thickener in patients with dysphagia. The enrolled patients were classified into mild and moderate-to-severe dysphagia groups. The primary outcome measure was degree of need for cyclic ingestion using test jelly for pharyngeal residuals (cyclic ingestion score). The secondary outcome was the patient's sense of material remaining in the throat following swallowing. Sixty-two patients (58% men; mean age 83 ± 9 years) with dysphagia were included. They were classified into mild dysphagia (n = 26) and moderate-to-severe dysphagia (n = 36) groups. In the moderate-to-severe dysphagia group, pharyngeal residuals were significantly less likely with pureed diets using a gelling agent than with those using a xanthan gum-based thickener, with respective median cyclic ingestion scores (range) of 1 (0-4) vs. 2.5 (0-4) (p = 0.001). There was no significant difference in pharyngeal residuals between the pureed diets in the mild dysphagia group. The multivariate analysis identified gelling agent as an important factor significantly associated with less pharyngeal residual after swallowing of pureed diet in patients with moderate-to-severe dysphagia. Pureed diets thickened by a gelling agent decrease pharyngeal residues in patients with moderate-to-severe dysphagia and may reduce risk of aspiration pneumonia.

Dysphagia 2024:10.1007/s00455-024-10674-6.

Abstract
Texture modification in the form of gels or jellies is used for patients with dysphagia. For over 20 years, our group has been using gelatin jellies, a type of gel, as a starting diet for patients with dysphagia. Gelatin jellies are served in a small-sliced form and swallowed whole. In sliced jelly whole swallowing (SJWS), sliced gelatin jelly (SGJ) passes through the pharynx in one lump without collapsing. This study aimed to examine the usefulness of SJWS. We analyzed the images of videofluoroscopic swallowing studies performed using the normalized residue ratio scale (NRRSv: vallecula, NRRSp: pyriform sinus), the penetration-aspiration scale (PAS), and pharyngeal transit time (PTT) in 50 patients with dysphagia and compared the results in a prospective study. SJWS had significantly less residue in both NRRSv and NRRSp than in moderately thickened liquid swallowing. No significant differences in PAS scores were found between SGJ and moderately thickened liquid. Additionally, no significant differences in PTT scores were noted between the two. This study demonstrated the usefulness of SJWS in improving swallowing safety in patients with dysphagia. Further studies are needed to evaluate the reproducibility of the test, the comparison of SGJ with other thickened liquids, and the safety of SJWS for different diseases.

Uno I, Kubo T. Risk Factors for Aspiration Pneumonia among Elderly Patients in a Community-Based Integrated Care Unit: A Retrospective Cohort Study. Geriatrics (Basel) 2021; 6:geriatrics6040113. [PMID: 34940338 PMCID: PMC8702067 DOI: 10.3390/geriatrics6040113] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Revised: 11/18/2021] [Accepted: 11/26/2021] [Indexed: 01/12/2023] Open
Abstract
We aimed to clarify the physical factors associated with the incidence of aspiration pneumonia in a community-based integrated care unit. This retrospective cohort study included 412 patients aged 65 years or older admitted to a community-based integrated care unit. A new diagnosis of aspiration pneumonia made by the attending physician based on physical examination, imaging findings, and blood test data after 48 h of admission was considered as an incidence of aspiration pneumonia. Basic patient information, activities of daily living, swallowing function, nutritional status, cognitive function, oral health-related factors, and energy intake were retrospectively investigated. We classified the patients into a pneumonia group and a non-pneumonia group, and examined the factors associated with the development of aspiration pneumonia. The mean age was 86.9 ± 8.1 years, and the pneumonia group comprised 49 participants. Comparison between the groups showed significant differences in oral environment, denture use, cognitive functional independence measure, and discharge to home. In multivariate logistic regression analysis, oral environment (odds ratio (OR) = 0.229, 95% confidence interval (CI): 0.070–0.753, p = 0.015) and use of dentures (OR = 0.360, 95% CI: 0.172–0.754, p = 0.007) were independently associated with aspiration pneumonia. Oral care and the use of dentures may be effective in preventing aspiration pneumonia.
