Background & Aims: The relationship between vitamin D and oropharyngeal dysphagia (OD) is still poorly understood. The aim of this study was to evaluate 25-hydroxyvitamin D [25(OH)D] concentration in patients with OD and to verify its association to nutritional status, functional independence measure (FIM), time of clinical signs (TCS) and OD severity. This is a cross-sectional study conducted with outpatients. Body mass index (BMI), FIM, TCS, causes of OD, comorbidities, penetration-aspiration scale (PAS) and severity scale were evaluated., Methods: A multiple linear regression and effect size were performed to evaluate the association between serum 25(OH)D concentration and independent variables., Results: Forty-eight participants were included, with a mean age of 60.1 ± 15.3 years. The mean of the 25(OH)D concentration was 26.10 ± 12.0 ng/mL. The prevalence of hypovitaminosis D (<30 ng/mL) was 73%. In the multiple linear regression analysis (adjusted for sex, age, BMI, dietary intake and solar radiation), 25(OH)D concentration was significantly related with the TCS (p = 0.01, f 2  = 0.48). Patients with hypovitaminosis D had a moderate effect (p = 0.08, δ = 0.36) for a lower FIM score., Conclusions: These findings indicate that serum 25(OH)D concentration may be related to the TCS and the functional capacity of patients with OD., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2020 European Society for Clinical Nutrition and Metabolism.

Background & Aim: Oropharyngeal dysphagia (OD) can lead to a deficiency of antioxidant micronutrients. The aim of the present study was to investigate the relation between OD and nutritional status, antioxidant vitamins (β-carotene, vitamin E and C) and serum markers of the inflammatory response [C-reactive protein, myeloperoxidase (MPO), nitric oxide metabolites (NOx), tumor necrosis factor-α, interleukin (IL)-1β and IL-6] in adults and elderly., Methods: A cross-sectional study was conducted with 69 individuals: 22 in the control group (CG) and 47 in the OD group (ODG). The ODG was subdivided into ODG-mild = normal oral feeding (OF, n = 14), ODG-moderate (OF-modified, n = 22) and ODG-severe (OF-suspended, n = 11). Associations were investigated using multiple linear regression., Results: The body mass index (BMI) was higher in the ODG compared to the CG (p = 0.008), independently of sex, age, energy intake (EI) and score on the Functional Independence Measure. BMI was significantly lower in the ODG-severe compared to the ODG-mild (p = 0.012). OD was associated with lower concentrations of β-carotene (p < 0.001) and vitamin C (p < 0.001), independently of sex, age and EI, and higher concentrations of MPO (p = 0.008) and NOx (p = 0.011), independently of sex, age and the presence of comorbidities., Conclusion: Adults and elderly with OD have lower levels of antioxidant vitamins (β-carotene and vitamin C) and a high inflammatory response (MPO and NOx). The evaluation of antioxidant vitamins could be incorporated in nutritional status assessment in this population., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2020 European Society for Clinical Nutrition and Metabolism.

Background & Aims: Oropharyngeal dysphagia (OD) and comorbidities can exert an influence on nutritional status and contribute to mortality. The aim of the present study was to examine relationships between high Charlson Comorbidity Index (CCI) scores and OD outcomes, including OD severity, feeding route, nutritional status and one-year mortality rate in adults and elderly individuals., Methods: A longitudinal study, whose the final sample comprised 110 patients with OD and 75 of whom were evaluated for one-year mortality outcome. Swallowing (videofluoroscopy), nutritional status [body mass index (BMI)], CCI, type of feeding route, medications and hospitalization were evaluated. Multinomial logistic regression was performed to calculate the unadjusted and adjusted odds ratios (OR) and 95% confidence intervals (95%CI)., Results: Overall sample of the study were adults and elders with a median age (years) of 61.3 [interquartile range (IQR): 58.4-64.2]. The median CCI was 2.3 (IQR: 2.1-2.6) and the mortality rate was 10.8%. Hospitalization was significantly associated with underweight (p = 0.013) and number of medications (p = 0.023). After adjustment, sex/age and nº-Medications/Hospitalization (nº-M/H), CCI ≥3 was associated with nasogastric tube feeding (OR 4.57, 95%CI 1.59-13.1 and OR 3.39, 95%CI 1.21-9.51 respectively) and swallowing performance (OR 0.73, 95%CI 0.59-0.90 and OR 0.74, 95%CI 0.61-0.90 respectively)., Conclusions: A high CCI was associated with OD severity and feeding route, but not with nutritional status or mortality., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2020 European Society for Clinical Nutrition and Metabolism.
