Dysphagia not only leads to physical complications but also exerts a negative emotional impact, resulting in a decline in quality of life. The purpose of the study was to investigate the association between dysphagia and depressive symptoms at the population level while accounting for various demographics and health conditions. This study was a cross-sectional design using the 2022 National Health Interview Survey. The study subjects were American adults who completed the survey questionnaires about depressive symptoms, swallowing problems, and health conditions. Regression models and three different propensity score matching approaches were utilized to estimate associations between dysphagia and depressive symptom. Data analyzed in the study showed that among 25,651 U.S. adults, 1,664 (6.48%) reported dysphagia. Among patients with dysphagia, 976 (58.65%) were women, and the average age was 55.48 years. The differences in demographics and health conditions between individuals with and without dysphagia were balanced by three propensity score matching approaches (p >.05). After adjustments using population-weighted multivariable logistic regression, the inverse probability of treatment weighting (IPTW) with both normalized weights, IPTW with stabilized weights, and Greedy algorithms with 1:1 matching method, the risks of having depressive symptom in those with dysphagia were significantly higher than those without dysphagia (odds ratios ranged from 1.763 to 2.402, p <.0001). The study supports that dysphagia and depressive symptoms frequently co-occur in U.S. adults, highlighting the need for comprehensive care that addresses both physical and mental health aspects of swallowing impairments.</p>","PeriodicalId":11508,"journal":{"name":"Dysphagia","volume":" ","pages":"728-736"},"PeriodicalIF":3.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142521368","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}

Nasal airflow and sound signals were recorded using a nasal cannula-type flow sensor and contact microphone, which were synchronized with videofluoroscopic swallowing studies (VFSS). For healthy controls, only nasal airflow and sound signals recordings were conducted. A 5 ml thickened liquid was utilized during these assessments. The penetration-aspiration scale (PAS) score was determined through VFSS. Various parameters, including swallowing apnoea duration (SAD), swallowing duration (SD), swallowing latency duration (SLD), number of swallows (NS), and RSC patterns, were analysed to assess RSC. A total of 37 patients with PSD following IS-comprising 25 non-aspirators and 12 aspirators-and 31 age-matched healthy controls were included. The PSD patient group exhibited a shorter SAD (p = 0.016), a longer SD (p = 0.000), and fewer NS (p = 0.000) compared to the healthy control group. Among the PSD patients, those who aspirated exhibited a notably shorter SAD (p = 0.018) and longer SD (p = 0.028) compared to non-aspirators. The prevalence of the swallow-inspiration pattern was higher in PSD patients (p = 0.006), particularly among those who aspirated (p = 0.010). Logistic regression analysis and the area under the receiver operating characteristic curve (AUC) indicated that both SAD (AUC = 0.825, p = 0.002) and SD (AUC = 0.757, p = 0.020) were significant predictors of aspiration.

Additionally, this study attempted to differentiate the personal abilities of individuals with dysphagia and hierarchize item difficulties using the ICF-based Item Response Theory (IRT) modeling approach. This cross-sectional study enrolled a cohort of 150 patients with dysphagia (105 male and 45 female) from a tertiary hospital in China. Participants were assigned to evaluate the 114-item ICF dysphagia questionnaire. To further assess their swallowing capabilities, eating patterns, quality of life, and nutritional status, participants underwent a battery of five additional scales. The ICF qualifiers underwent data shaping including dichotomization and missing value imputation, Mokken scale analysis (MSA) for checking unidimensionality, local independence, monotonicity, and invariant item ordering (IIO), and parametric IRT modeling for identifying an optimal model from the 1-parametric logistic model (1PLM), 2PLM, 3PLM, and 4PLM. Finally, we tested the robustness of the optimal model via Monte Carlo simulation and illustrated the usefulness of the model by its person-item map. The 1PLM emerged as the optimal model with a total of 50 ICF items (12 'd-Activities and Participation', 33 'b-Body Functions', and 5 'e-environmental' items). The final scale presented strong reliability with Cronbach's Alpha = 0.967.

The findings also demonstrated measurement equivalence of the final model for individuals with different genders or across various age groups. The utilization of the person-item map can effectively compare the difficulty levels of items with the abilities of patients, thereby facilitating the delivery of tailored care and precise rehabilitation strategies that match the individual competency of those suffering from dysphagia.

A retrospective single institution cohort study was performed on patients diagnosed with functional EGJOO on high-resolution manometry (HRM). Clinical, demographic, endoscopic and imaging parameters were recorded. Univariate and multivariate analyses were performed to identify factors associated with reduced likelihood of symptom resolution.

The study included two groups; 'Group I (N = 90)' who had a neurological disorder and their parents, and 'Group II (N = 60)' who were typically developing children without any feeding and swallowing problems and their parents. Limited literature review, clinical experience, and parental interviews have been used in creating the item pool. A panel of 7 experts assessed the content validity in two Delphi rounds. Cronbach's α measured the internal consistency of each item. The test-retest reliability was determined using the FF-PR scores given by the parents in Group I one week apart. Confirmatory factor analysis was used to measure the construct validity. The Nordic Orofacial Screening Test (NOT-S), Dysphagia Disorder Survey (DDS), and the Turkish version of the Feeding-Swallowing Impact Survey (T-FS-IS) were used for the criterion validity of the FF-PR. The discriminant validity of the FF-PR was determined by comparing the FF-PR scores of the groups and using the receiver-operating characteristic (ROC) curve. The content validity index was 0.92. The Cronbach's α was found to be high (test: 0.966, retest: 0.969).

One mechanism that might explain these physiological differences is the structure of the nipple an infant is feeding on. Breasts in most mammals are ducted soft-tissue structures that require suction to be generated for milk to be released, whereas bottle nipples are hollow and allow milk to be acquired by compression of the nipple. We used a validated animal model (pigs) to test how being raised on a novel ducted nipple impacted feeding physiology and performance compared to infants raised on a standard (cisternic) nipple. At the end of infancy, we fed both groups with both nipple types and used high-speed videofluoroscopy synchronized with intraoral pressure measurements to evaluate feeding function. Nipple type did not have a profound impact on sucking or swallowing rates. However, when feeding on a ducted nipple, infant pigs raised on a ducted nipple generated more suction, consumed milk at a faster rate, swallowed larger boluses of milk, and had decreased likelihood of penetration and aspiration than those raised on a cisternic nipple.
