Article Synopsis
  • The study investigates the fractional exhaled nitric oxide (FeNO) levels in a healthy population to better understand normal ranges and their influencing factors.
  • FeNO levels were measured in 2,251 participants aged 6-82 years, revealing median values that increase with age and vary based on gender, height, and eosinophil counts.
  • The findings establish reference ranges for FeNO that can aid in clinical asthma diagnosis and management.

Background: Oscillometry devices allow quantification of respiratory function at tidal breathing but device-specific reference equations are scarce: the present study aims to create sex-specific oscillometric reference values for children and adolescents using the Resmon PRO FULL device.

Methods: Healthy participants (n=981) aged 6 to 17 years of the Austrian LEAD general population cohort were included. Subjects had normal weight (body mass index ≤99th percentile) and normal lung volumes (total lung capacity (TLC) ≥ lower limit of normal).

In patients with airflow obstruction, the levels of biomarkers of Type-2 (T2) inflammation serve to predict the effectiveness of inhaled corticosteroid and biological therapies. Elevated biomarkers of T2 inflammation, including fractional exhaled nitric oxide (FeNO, ≥20 ppb) and blood eosinophil counts (BEC, ≥300 cells/µL), were investigated in a population-based cohort of the Austrian LEAD study. A total of 4976 individuals (aged 18-82 years) were categorised into four groups based on their FeNO and BEC levels: normal with FeNO < 20 ppb and BEC < 300 cells/µL (n = 2634); FeNO ≥ 20 ppb only (n = 1623); BEC ≥ 300 cells/µL only (n = 340); and FeNO ≥ 20 ppb and BEC ≥ 300 cells/µL (n = 379).

Article Synopsis
  • The research focuses on the Higgs mode in a strongly interacting Fermi gas transitioning from a fermionic to a bosonic superfluid.
  • By adjusting the interaction strength of the gas, the researchers excite the Higgs mode and measure its resonance frequency and line width based on different interaction strengths and temperatures.
  • They discover that at low temperatures, the resonance frequency aligns with a theoretical model, and both frequency and line width remain relatively stable with temperature, contrary to theoretical expectations but in line with another recent study.

Pulsatile hemodynamics have been shown to be independent predictors of cardiovascular events. The aim of the current study was to describe four pulsatile hemodynamic markers in a large, well-established, population-based cohort and to provide reference equations for sex- and age-based standardization of these measurements. 6828 adult participants from the Austrian LEAD (Lung, hEart, sociAl, boDy) cohort study, who were free from overt cardiovascular disease, non-diabetic based on blood test results, and had no history of pharmacological treatment for hypertension, dyslipidemia, and diabetes, comprised the "reference population".
