Do frail elderly people affect the nursing workload in intensive care units?

Objective: Compare the nursing workload according to the condition of frailty in elderly people in an intensive care unit (ICU).

Method: A cross-sectional study whose sample included patients aged ≥60 years who were hospitalized for ≥24 hours in the ICU of a university hospital in São Paulo, Brazil. The Tilburg Frailty Indicator (TFI) was used to identify frailty in elderly people and the Nursing Activities Score (NAS) was used to measure the nursing workload.

Neuroanatomical and physiological evidence that the retrotrapezoid nucleus/parafacial region regulates expiration in adult rats.

The rostroventrolateral medulla contains two functional neuronal populations: (1) the parafacial respiratory group (pFRG) neurons and (2) the chemosensitive retrotrapezoid nucleus (RTN) neurons. Using anatomical and physiological techniques, we investigated the role of the RTN/pFRG in CO2-induced active expiration (AE) in urethane-anesthetized rats. Anterograde tracing using biotinylated dextran amine (BDA) revealed dense neuronal projections emanating from the RTN/pFRG to the caudal ventral respiratory group (cVRG), 60% of which contained vesicular glutamate transporter-2.
