Short-term Oral Nitrite Administration Decreases Arterial Stiffness in Both Trained and Sedentary Wistar Rats.

Background: Nitric Oxide (NO) plays an important role in blood pressure (BP) regulation, acting directly on peripheral vascular resistance through vasodilation. Physical training (via eNOS/NO) and intake of nitrite have been considered major stimuli to increase NO.

Objective: We examined the effects of oral nitrite administration and aerobic exercise training on BP and arterial stiffness in Wistar rats.

Lesson in understanding parents' perspective: perception of quality of care and COVID-19-related fears among users of paediatric health services over the COVID-19 pandemic in 11 facilities in Italy.

Background: The COVID-19 pandemic had an important psychological impact on children and their families. This study aims to explore paediatric health services users' perceptions of quality of care (QOC) and COVID-19-related fears, and their evolution over time in relation to COVID-19 pandemic.

Methods: In a multicentre cross-sectional study involving 11 public hospitals providing paediatric care across the Italian territory, we collected data from services users through a validated questionnaire.

Synergistic activity of an RNA polymerase PA-PB1 interaction inhibitor with oseltamivir against human and avian influenza viruses in cell culture and in ovo.

In search of novel therapeutic options to treat influenza virus (IV) infections, we previously identified a series of inhibitors that act by disrupting the interactions between the PA and PB1 subunits of the viral RNA polymerase. These compounds showed broad-spectrum antiviral activity against human influenza A and B viruses and a high barrier to the induction of drug resistance in vitro. In this short communication, we investigated the effects of combinations of the PA-PB1 interaction inhibitor 54 with oseltamivir carboxylate (OSC), zanamivir (ZA), favipiravir (FPV), and baloxavir marboxil (BXM) on the inhibition of influenza A and B virus replication in vitro.

Continuous Infusion of Dexmedetomidine for Maintenance of Sedation in an Aggressive Adolescent with Autism Spectrum Disorder in the Emergency Department.

Background: The treatment of aggressive behavior and agitation in pediatric patients with autism spectrum disorder (ASD) in the emergency department is topical and challenging.

Case Presentation: We described an adolescent with autism spectrum disorder treated ten times in the pediatric emergency department for severe episodes of aggressiveness and agitation. After resolving the acute phase of these behavioural crises, sedation was maintained with a continuous infusion of dexmedetomidine to prevent the resurgence of agitation and to organize discharge properly, considering the family's needs.
