Exhaled Nitric Oxide and Sputum Eosinophils Are Complementary Tools for Diagnosing Occupational Asthma.

Background: Exposure-related changes in exhaled nitric oxide (FeNO) and sputum eosinophils have not been thoroughly compared in the investigation of occupational asthma.

Objective: This study aimed at comparing the accuracies of the changes in FeNO concentrations and sputum eosinophil counts in identifying asthmatic reactions induced by occupational agents during specific inhalation challenges (SICs).

Methods: This retrospective multicenter study included 321 subjects who completed an assessment of FeNO and sputum eosinophils before and 24 h after SICs with various occupational agents, of whom 156 showed a positive result.

Dynamic survival prediction of end-stage kidney disease using random survival forests for competing risk analysis.

Background And Hypothesis: A static predictive model relying solely on baseline clinicopathological data cannot capture the heterogeneity in predictor trajectories observed in the progression of chronic kidney disease (CKD). To address this, we developed and validated a dynamic survival prediction model using longitudinal clinicopathological data to predict end-stage kidney disease (ESKD), with death as a competing risk.

Methods: We trained a sequence of random survival forests using a landmarking approach and optimized the model with a pre-specified prediction horizon of 5 years.

The effects of plasma exchange and glucocorticoids on early kidney function among patients with ANCA-associated vasculitis in the PEXIVAS trial.

Therapeutic plasma exchange (PLEX) is an adjunctive treatment for patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis and kidney involvement. Little is known about the effect of PLEX on early changes in kidney function. This post-hoc analysis of the PEXIVAS trial investigated the effects of PLEX on changes in kidney function within 12 months.

Temporal Order and Developmental Context of Aggressive Attitude and Aggressive Behavior: Testing a Within-Person Reciprocal Effects Model.

Introduction: The purpose of this study was to determine whether the relationship between aggressive attitude and aggressive behavior is reciprocal or bidirectional in nature.

Method: A sample of 845 early adolescent youth (406 boys, 439 girls) between the ages of 10 and 13 (mean = 11.21) served as participants in this study.

Youth engagement in global conservation governance.

Youth are increasingly recognized for their important role in shaping environmental decisions surrounding conservation. Regrettably, youth who are crucial decision-makers are often excluded from environmental governance spaces due to structural barriers, both economic and political. As highlighted by recent environmental justice literature, this marginalization hinders their active participation in the decision-making process.
