Cross-cultural adaptation and metric analysis of the Adult Difficult Intravenous Access Scale for use in Brazil.

Objective: to cross-culturally adapt and analyze the metric properties of the Adult Difficult Intravenous Access Scale into Brazilian Portuguese.

Method: methodological study carried out in two stages: 1) Translation of the scale from the original version in English to Brazilian Portuguese, including an assessment by a committee of nine judges, back-translation and semantic analysis; 2) Analysis of metric properties with 130 adults admitted to a hemodynamics unit in which difficult peripheral venipunctures occurred. Participants were followed up to check for the occurrence of difficult peripheral venipunctures.

Sports experience, affects and life satisfaction in Portuguese athletes with disabilities.

This study aims to validate the Portuguese version of the Satisfaction with Life Scale (Cronbach's alpha = 0.82) and the Positive and Negative Affect Scale (Cronbach's alpha = 0.86 for positive affect and 0.

Muscle tissue oxygenation in individuals with peripheral arterial disease of different walking abilities: An exploratory study.

Background: Blood flow restriction caused by peripheral arterial disease (PAD) is reflected in reduced walking capacity. The peripheral mechanisms that may affect the walking capacity of individuals with PAD are not yet fully understood. This study aimed to 1) compare tissue oxygenation and muscle metabolism of individuals with PAD with different walking capacities and 2) evaluate which variables have the greatest potential to explain the variability in distance walked between performance levels.

Sustained swimming and improvements in anti-oxidative stress responses in matrinxa (Brycon amazonicus) exposed to environmental nitrite.

Nitrite is usual in water of intensive rearing systems. Considering its oxidative harmful potential, it was selected to challenge matrinxa Brycon amazonicus reared in sustained swimming (SS) (with flowing water adjusted to speed at 1.0 BL seg (long-duration aerobic metabolic characteristic) and evaluate any beneficial effect of such rearing system to enhance the fish potential to cope with this oxidant stressor in fish farmings.
