Respiratory physiological changes post initiation of neurally adjusted ventilatory assist in preterm infants with evolving or established bronchopulmonary dysplasia.

To assess respiratory changes after neurally adjusted ventilatory assist (NAVA) initiation in preterm infants with evolving or established bronchopulmonary dysplasia (BPD). Premature infants born less than 32 weeks gestation with evolving or established BPD initiated on invasive or non-invasive (NIV) NAVA were included. Respiratory data: PCO and SpO₂/FiO₂ (S/F) ratio before and at 4, 24, 48 h post-NAVA initiation were collected.

Unlabelled: Post-acute sequelae of COVID-19 involves several organs, but its basis remains poorly understood. Some infected cells in mice survive the acute infection and persist for extended periods in the respiratory tract but not in other tissues. Here, we describe two experimental models of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection to assess the effect of viral virulence on previously infected cells.

Helicase is a nucleic acid motor that catalyses the unwinding of double-stranded (ds) RNA and DNA via ATP hydrolysis. Helicases can act either as a nucleic acid motor that unwinds its ds substrates or as a chaperone that alters the stability of its substrates, but the two activities have not yet been reported to act simultaneously. Here, we used single-molecule techniques to unravel the synergistic coordination of helicase and chaperone activities, and found that the severe acute respiratory syndrome coronavirus helicase (nsp13) is capable of two modes of action: (i) binding of nsp13 in tandem with the fork junction of the substrate mechanically unwinds the substrate by an ATP-driven synchronous power stroke; and (ii) free nsp13, which is not bound to the substrate but complexed with ADP in solution, destabilizes the substrate through collisions between transient binding and unbinding events with unprecedented melting capability.

Objective: This study aimed to assess the safety and efficacy of tissue Plasminogen Activator (tPA) in patients with COVID-19-induced severe Acute Respiratory Distress Syndrome (ARDS).
Methods: The intervention group consisted of eligible patients with severe ARDS due to COVID-19 admitted to the Intensive Care Unit (ICU) of a university hospital. We selected the control group from admitted patients treated in the same ICU within the same period.

Kawasaki disease (KD) is an acute vasculitis mainly seen in children, with a specific risk for coronary artery involvement. Atypical symptoms can sometimes result in missed diagnoses, delaying necessary treatment and increasing the chances of serious cardiovascular complications. We report a case of a six-month-old previously healthy girl who had not been vaccinated.
