Parenting of mothers of children in early childhood during the COVID-19 pandemic: qualitative research.

Objectives: to understand practices of mothers of children in early childhood who live in contexts of poverty in the face of the COVID-19 pandemic.

Methods: an exploratory, descriptive and qualitative study. Participants were selected in the community context, composing an intentional sample to be collected through semi-structured online interviews.

The influence of lung function and muscular strength on the functional capacity of chronic obstructive pulmonary disease patients.

Aim: To determine which variable (forced expiratory volume in 1 second (FEV1), partial pressure of oxygen in arterial blood (PaO2), nocturnal hypoxaemia and muscular strength of femoral quadriceps) can predict the distance walked in the six-minute walk test (6MWT) by COPD patients.

Methods: A cross-sectional and observational study of thirty patients referred to a pulmonary rehabilitation programme at a university hospital. Lung function was evaluated by spirometry, arterial blood gas analysis and nocturnal oximetry.
