Objectives: Chronic rhinosinusitis (CRS) is prevalent in the Cystic Fibrosis (CF) population. CRS exacerbations in CF are thought to contribute to pulmonary exacerbations. Literature regarding the impact of endoscopic sinus surgery (ESS) is inconclusive. This study examines rates of lung function decline and pulmonary exacerbation in CF patients who have undergone ESS.
Design: Retrospective review of medical records.
Setting: Academic Hospital.
Participants: 40 adult CF patients.
Main Outcome Measures: Rate of lung function decline (% predicted Forced Expiratory Volume in 1 second [ppFEV ]), number of pulmonary exacerbations (IV/oral antibiotic therapy ± hospital admission) and total number days hospitalised 2-year postoperatively was collected. CRS patients undergoing ESS were matched to those without ESS by gender, age, and F508del genotype.
Results: Forty patients (mean age 37.4, 60% male) were reviewed. No significant difference was found between the surgical group and controls in baseline ppFEV (72.5% vs. 72.7%, P = .98), 2-year preoperative number of pulmonary exacerbations (3.05 vs. 1.65, P = .10), or Lund-Mackay scores (12.25 vs. 11.55, P = .71). No significant difference was found in 1-year (70.5% vs. 72.8%, P = .84) or 2-year (70.4% vs. 72.6% P = .80) postoperative ppFEV and 2-year postoperative pulmonary exacerbations (1.7 vs. 1.45, P = .87). A significant increase was identified in total number days hospitalised postoperatively (4.85, P = .02). In the surgical group, no significant difference was identified between preoperative and postoperative ppFEV , 1 year (-2.51%, P = .32) and 2 years after ESS (-3.10%, P = .51), postoperative rate of pulmonary exacerbations (-1.28, P = .11), or in total number days hospitalised (3.74, P = .14).
Conclusions: In this study, ESS does not appear to significantly improve ppFEV or decrease the number of pulmonary exacerbations postoperatively.

Background/objectives: Understanding the dynamic changes in nutritional status of patients with non-Hodgkin's lymphoma (NHL) during chemotherapy is crucial, as it significantly impacts chemotherapy-related toxicity and survival outcomes.
Subjects/methods: This multi-center study included newly diagnosed NHL patients. Nutritional status and chemotherapy-related toxic effects were assessed over the first five chemotherapy sessions, with follow-ups conducted every 3 months.

Chronic obstructive pulmonary disease (COPD) exacerbations frequently cause patient consultations in both out- and inpatient settings. Recent data suggest that only 40-60% of exacerbations are of bacterial origin and mandate antibiotic treatment. However, a reliable tool to justify prescribing antibiotics for COPD exacerbation is still lacking.

Although alveolar hyperoxia exacerbates lung injury, clinical studies have failed to demonstrate the beneficial effects of lowering the fraction of inspired oxygen (FO) in patients with acute respiratory distress syndrome (ARDS). Atelectasis, which is commonly observed in ARDS, not only leads to hypoxemia but also contributes to lung injury through hypoxia-induced alveolar tissue inflammation. Therefore, it is possible that excessively low FO may enhance hypoxia-induced inflammation in atelectasis, and raising FO to an appropriate level may be a reasonable strategy for its mitigation.

Introduction: Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder among children with attention deficit hyperactivity disorder (ADHD). This study aims to determine the prevalence of OSA in children with ADHD, compare the differences in clinical characteristics between children with ADHD-OSA and those without OSA (ADHD-nonOSA), and to identify the correlation between OSA and ADHD in children.
Methods: This cross-sectional descriptive study was conducted on 524 children with ADHD, aged 6-12 years, at the Vietnam National Children's Hospital from October 2022 to September 2023.

Chronic obstructive pulmonary disease (COPD) is a leading cause of death worldwide and greatly reduces the quality of life. Utilizing remote monitoring has been shown to improve quality of life and reduce exacerbations, but remains an ongoing area of research. We introduce a novel method for estimating changes in ease of breathing for COPD patients, using obstructed breathing data collected via wearables.
