The relationship of serum 25-hydroxyvitamin D concentration with clinical variables in patients with oropharyngeal dysphagia.

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.

Relationships between high comorbidity index and nutritional parameters in patients with Oropharyngeal Dysphagia.

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.

Relationship between oropharyngeal dysphagia, nutritional status, antioxidant vitamins and the inflammatory response in adults and elderly: A cross-sectional study.

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).

Factors associated with malnutrition in adolescent and adult patients with cystic fibrosis.

Objective: To determine the prevalence of malnutrition in patients attending an adult cystic fibrosis (CF) program and to investigate the associations of malnutrition with the clinical characteristics of those patients.

Methods: This was a cross-sectional study involving patients with clinically stable CF patients (16 years of age or older). The patients underwent clinical assessment, nutritional assessments, pulmonary function tests, and pancreatic function assessment.
