Aim: To determine the effect of long-term tobramycin (TOB) inhalation therapy on recurrent pneumonia among ventilator-dependent children with profound neurological disabilities.
Methods: TOB inhalation was performed in eight series of trials in seven ventilator-dependent children who had intratracheal Pseudomonas aeruginosa and suffered from recurrent pneumonia. Their age at the initiation of therapy was 68 ± 50 months (mean ± standard deviation), whereas the duration of treatment was 30 ± 22 months. The participants were followed after the termination of therapy for a period of 38 ± 32 months.
Results: The annual rate of pneumonia was 5.6 episodes per year (n = 8) preceding the initiation of inhalation, which decreased to 3.7 (n = 8), 1.6 (n = 5), and 0.67 (n = 3) in the periods of 0-12, 12-24, and 24-36 months after initiation, respectively. The rates were 1.0 (n = 6), 0.6 (n = 5), and 1.4 (n = 5) in the periods of 0-12, 12-24, and 24-36 months after the termination of therapy.
Interpretation: Extended TOB inhalation therapy was effective in decreasing the morbidity of pneumonia in ventilator-dependent children with severe motor and intellectual disabilities.

Introduction: The increasing prevalence of electronic nicotine delivery systems and alcohol drinking has led to increases in nicotine and alcohol co-use. However, the impact of ENDs on brain activity and binge drinking behavior is not fully understood.
Aims And Methods: We subjected female and male C57BL/6J mice to a voluntary drinking and electronic nicotine vapor exposure paradigm.

Introduction: Adolescent usage of electronic cigarettes has increased globally. Inconsistent, or absent, labelling of nicotine and other ingredients requires chemical analysis to accurately determine the chemical composition of these products.
Methods: Electronic cigarettes confiscated from public and private high school students (N=598) were provided for analysis from three regions in New South Wales, Australia.

Objectives: This study aimed to evaluate the efficacy of inhaled cationic antibiotics, including tobramycin (TOB) and colistin (CST), using an in vitro alginate bead model that simulates Pseudomonas aeruginosa lung biofilms.
Methods: Bioluminescent P. aeruginosa were encapsulated within alginate beads and dispersed in either Mueller-Hinton broth (MHB) or artificial sputum medium (ASM).
