Empathetic solicitude attenuates the affective and sensory dimensions of CO-induced dyspnea: A randomized parallel arm experimental trial in healthy humans.

Dyspnea testifies to profound suffering in patients and its relief is a priority for caregivers. This can be achieved by correcting causative disorders ("etiopathogenic" approach) or targeting the dyspnea itself ("symptomatic" approach), as is done for pain. Empathetic solicitude from caregivers has an intrinsic analgesic effect, but its effects on dyspnea have not been formally documented.

"In their own words": delineating the contours of dyspnea invisibility in patients with advanced chronic obstructive pulmonary disease from quantitative discourse analysis.

Background: Dyspnea conveys an upsetting or distressing experience of breathing awareness. It heavily weighs on chronic respiratory disease patients, particularly when it persists despite maximal treatment of causative abnormalities. The physical, psychological and social impacts of persistent dyspnea are ill-appreciated by others.

Short-term cognitive loading deteriorates breathing pattern and gas exchange in adult patients with congenital central hypoventilation syndrome.

Question: Human mutations result in life-threatening sleep-related hypoventilation (congenital central hypoventilation syndrome, CCHS). Most patients retain ventilatory activity when awake through a respiratory-related cortical network. We hypothesised that this need to mobilise cortical resources to breathe would lead to breathing-cognition interferences during cognitive loading.
