NCT07417657
Respiratory syncytial virus (RSV) is a leading cause of severe lower respiratory tract infection in young children, and a substantial proportion of severe cases occur in previously healthy infants. The gut-lung axis suggests that gut microbiome composition may modulate respiratory immune responses. This prospective observational study in Vietnam will compare gut microbiome profiles and systemic immune cytokine responses between infants with severe RSV infection and those with mild RSV infection, aiming to identify microbiome-immune signatures associated with disease severity.

Fasting in intensive care is mainly studied in mechanically ventilated patients or those in the weaning phase. Recent research challenge the common assumption of fasting and suggests that continuing enteral nutrition before extubation may be beneficial. Fasting is also practiced before procedures (e.g., tracheostomy, endoscopy) or surgeries, based on anesthetic guidelines. Yet, no data address fasting in non-intubated ICU patients with acute respiratory failure, despite frequent caloric deficits and inadequate nutritional intake. Aspiration risk often justifies fasting, but studies indicate that swallowing reflexes remain intact in patients receiving high-flow nasal oxygen or non-invasive ventilation. Moreover, although intubation carries a 2-5.9% aspiration risk, rapid sequence induction mitigates this, questioning the necessity of preventive fasting. Despite its prevalence, this practice lacks scientific validation and guideline support. Patient discomfort is also significant. Hunger and thirst are major sources of distress, and evidence from anesthesiology suggests that allowing fluid intake pre-anesthesia reduces discomfort. Extrapolating these findings to ICU patients could improve well-being. In conclusion, fasting in ICU patients may contribute to discomfort, dehydration, and malnutrition, while its protective benefits remain uncertain. We hypothesize that maintaining oral intake does not increase the risk of intubation or aspiration-related complications.
