Rationale: Virus-induced wheezing episodes in infancy often precede the development of
asthma. Whether infections with specific viral pathogens confer differential future asthma risk …

BACKGROUND: The contribution of viral respiratory infections during infancy to the development
of subsequent wheezing and/or allergic diseases in early childhood is not established. …

Rationale: Aeroallergen sensitization and virus-induced wheezing are risk factors for asthma
development during early childhood, but the temporal developmental sequence between …

Rationale: Human rhinoviruses (HRVs) consist of approximately 160 types that cause a wide
range of clinical outcomes, including asymptomatic infections, common colds, and severe …

Background Detection of either viral or bacterial pathogens is associated with wheezing in
children; however, the influence of both bacteria and viruses on illness symptoms has not …

Background Early life rhinovirus (RV) wheezing illnesses and aeroallergen sensitization
increase the risk of asthma at school age. Whether these remain risk factors for the persistence …

BACKGROUND: Exacerbations of childhood asthma and rhinovirus infections both peak
during the spring and fall, suggesting that viral infections are major contributors to seasonal …

Purpose: To prospectively compare apparent diffusion coefficient (ADC) measurements
derived from diffusion-weighted hyperpolarized helium 3 ( 3 He) magnetic resonance (MR) …

Rationale: Aerosol generation with modes of oxygen therapy such as high-flow nasal cannula
and noninvasive positive-pressure ventilation is a concern for healthcare workers during …

Background Prediction of subsequent school-age asthma during the preschool years has
proven challenging. Objective To confirm in a post hoc analysis the predictive ability of the …
