    Association Between Subglottic Pressure and Pulmonary Function in Individuals With Parkinson's Disease
    (2020) Castillo, Adrian; Castillo, Javiera; Reyes, Alvaro
    Introduction. In individuals with Parkinson's disease (PD), pulmonary complication such as weakness and rigidity of respiratory muscles and reduced cough airflow may be associated with reduced voice production due to limited pulmonary capacity and reduced airflow needed to vibrate the vocal folds. It is not clear, however, which pulmonary function parameter is determinant in the association with peak subglottic pressure (SGP). Therefore, the purpose of this study was to determine the association between peak SGP and pulmonary function parameters in individuals with PD.

    Factors that limit adherence to diet and quality of life in Chilean celiac patients during COVID-19.
    (2021) Parada, Alejandra; Espino E, Alberto; Reyes, Alvaro; Santibanez, Helga
    Background. Coronavirus disease (COVID-19) is highly contagious and dynamic confinement measures have shown to significantly reduce the number of infections, however, they can alter the availability of food, affecting adherence to a gluten-free diet (GFD) and quality of life (QoL) in celiac disease (CD). The objective of this study was to evaluate the limiting factors, adherence to a gluten-free diet and quality of life in people with celiac disease in a COVID-19 pandemic period. Methods. On-line surveys were applied regarding adherence to the GFD, CV, and factors that have generated difficulty in carrying out a GFD in this setting. Results. 216 surveys of celiac patients over 15 years of age were analyzed, of which 91% were women with an average age of 36 + 10.7 years and with 5.8 + 6.0 years of the disease. 56.48% had excellent adherence to the GFD and 43.52% had a good QoL. The high cost of gluten-free foods was the question with the highest response percentage, associated with regular and poor adherence to the GFD (p-value = 0.001) and with poor QoL (p-value = 0.023). Conclusion. In a COVID-19 pandemic period, the cost of food is associated with regular and poor adherence to the GFD and with poor QoL. Arch Latinoam Nutr 2021; 71(1): 54-60.

    The Effects of Respiratory Muscle Training on Phonatory Measures in Individuals with Parkinson's Disease
    (2020) Reyes, Alvaro; Castillo, Adrian; Castillo, Javiera; Cornejo, Isabel; Cruickshank, Travis
    Introduction. In individuals with Parkinson's disease (PD), respiratory muscle weakness and rigid-ity, bradykinesia of abdominal muscles and stiffness of the chest wall, affect the respiratory component of voice intensity due to reduced pulmonary capacity and airflow needed to vibrate the vocal folds. It may be possible to improve voice production by strengthening respiratory muscles. The purpose of this study was to evaluate the effects of inspiratory and expiratory muscle training on voice production outcomes in individuals with PD.
